= Recommenders
#figure(image("figures/amazon-recommendations.jpeg", height:80%))
== Overview
- "You don't know what you don't know"
- News, music, videos
- Serendipity
- _Unplanned fortunate discovery_
- Drive users to return to a platform
- Social media, online shopping, music
- Filters the entire data set into a subset the user hopefully is interested in
#pagebreak()
== Approach: Collaborative Filtering
#grid(rows: (auto, 1fr), gutter: 10pt,
[
- Recommend things liked by other similar people
- Uses explicit (ratings) or implicit (purchase history) data
],
figure(image("figures/collaborative-filtering.png"))
)
#pagebreak()
== Example: Amazon Item-to-Item
#figure(image("figures/amazon-item-to-item.png", height: 80%))
== Problems
- *Cold Start* --- For new people, not enough data to make good recommendations
- *Scalability* --- High-dimensional data, with many people it's challenging to find similar people
- *Sparsity* --- Doesn't work well if most items have no rating or preference data
#pagebreak()
#grid(rows: (auto, 1fr), gutter: 30pt, [
== Approach: Content-Based Filtering
], [
#grid(columns: (1fr, 1fr),[
- Uses attributes of the items and user's preferences
- Tunes the model from results
- Some preferences are weighted as more important than others
], figure(image("figures/content-based-filtering.jpeg")))
])
#pagebreak()
== Example: Pandora Radio
#columns(2)[
#figure(image("figures/pandora.png", height: 87%))
- Attributes of songs from Music Genome Project
- Likes, dislikes, skips used to model user preferences
#figure(image("figures/pandora-why.png"))
]
#pagebreak()
== Problems
- Doesn't work well across categories
- Movie preferences don't clearly translate to news
- Can continue to recommend the same kind of thing
- Variety is desirable for many domains, like music
- Requires accurate and detailed item attributes
- Amazon sells tens of millions of different products
#pagebreak()
== Hybrid Approaches
Most real-life systems use a combination of collaborative, content-based, and custom filtering.
#figure(image("figures/netflix-hybrid.png", height: 61%))
== Example: Netflix
- Collaborative filtering: Recommends based on other people who liked similar shows
- Content-based filtering: Recommends based on genre, categories, actors, release year, etc.
- Custom filtering: Time of day you watch, what device, how long you watch
- Asked to choose titles you like at signup (cold start)
- Recent preferences given more weight
#pagebreak()
== Examples
- What are some examples of recommender systems in your daily life?
- How do these systems use collaborative or content-based filtering?
- Would that product be better or worse without a recommender system?
#pagebreak()
== Group Exercise
- Read the provided article: #link("https://tinyurl.com/aicase2023")
- Split into groups and discuss:
- What harmful outcomes can recommender systems affect on individuals? On societey?
- What responsibility should organizations that use recommender systems have to mitigate harm?
- How can society mitigate the possible harms?
- We'll talk about what each group discussed as a class

[out], [of], [sight], [mind],
[2], [2], [1], [1])
#pagebreak()
= Bag of Concepts
Apply a weight to each word, then sum them.
#table(columns: (1fr, 1fr, 1fr, 1fr, 1fr), align: center,
[like], [love], [hate], [return], [...],
[0.2], [0.6], [-0.2], [-0.1], [...])
`I like this product` #sym.arrow.r $0 + 0.2 + 0 + 0 = 0.2$
`I love this product` #sym.arrow.r $0 + 0.6 + 0 + 0 = 0.6$
Can you think of problems with this approach?

#section("React Context")
By default, react uses the same context over everything. This means that
everything will be stored in one, which is not very scalable. Instead, we can
use react contexts, which solve this issue by providing a way to selectively
store and use "contexts" aka storages.//typstfmt::off
```js
// object to store
const themes = {
light: {
foreground: "#000000",
background: "#eeeeee",
},
dark: {
foreground: "#ffffff",
background: "#222222",
},
};
// create context
const ThemeContext = React.createContext(themes.light);
function App() {
return (
<ThemeContext.Provider value={themes.dark}>
<Toolbar />
</ThemeContext.Provider>
);
}
function ThemedButton() {
// use context in another component
const theme = useContext(ThemeContext);
return (
<button style={{
background: theme.background,
color: theme.foreground }}>
{" "}I am styled by theme context!{" "}
</button>
);
}
```
//typstfmt::on
Problems with this design, the contexts are still global, meaning you now have multiple global contexts which everyone can change. This leads to rather unmaintainable code.
#section("Redux: Predictable State Container")
- makes server side rendering possible -> only a possibility
- not a dependency of react -> can be used without
- tree based -> each state is a node of the tree
- changes cause a new tree to be created -> like haskell lists -> immutability, no
side effects, but slower performance
Example:\
#align(

#subsection("Reducer")
Reducer always has a slice of states, this means that you can run the reducer on multiple states at once.\
- multiple reducers allowed
- reducer always works on a slice of states, can be the entire tree -> root
Reducer, 1 state, or multiple
- root reducer needed in order to create the entire tree //typstfmt::off
```js
// create an empty object at the start
function rootReducer(state = {}, action) {
return {
balance: balance(state.balance, action),
transactions: transactions(state.transactions, action)
}
}
```
//typstfmt::on
Can also be done like this:
//typstfmt::off
```js
const rootReducer = combineReducers({
balance,
transactions
})
```
//typstfmt::on
#subsection("Store")
- rerenders components
- invoked by actions
- handles reducers
//typstfmt::off
```js
// create store with root reducer
const store = createStore(rootReducer);
// listen to changes on state
store.subscribe(() => console.log(store.getState()));
```
//typstfmt::on
#text(teal)[Note, this causes react to rerender the page on each state update.]
#align(center, [#image("../../Screenshots/2023_10_12_03_18_06.png", width: 50%)])
#subsection("Redux Example")
//typstfmt::off
```js
import { createStore } from 'redux'
/**
* This is a reducer - a function that takes a current state value and an
* action object describing "what happened", and returns a new state value.
* A reducer's function signature is: (state, action) => newState
*
* The Redux state should contain only plain JS objects, arrays, and primitives.
* The root state value is usually an object. It's important that you should
* not mutate the state object, but return a new object if the state changes.
*
* You can use any conditional logic you want in a reducer. In this example,
* we use a switch statement, but it's not required.
*/
function counterReducer(state = { value: 0 }, action) {
switch (action.type) {
case 'counter/incremented':
return { value: state.value + 1 }
case 'counter/decremented':
return { value: state.value - 1 }
default:
return state
}
}
// Create a Redux store holding the state of your app.
// Its API is { subscribe, dispatch, getState }.
let store = createStore(counterReducer)
// You can use subscribe() to update the UI in response to state changes.
// Normally you'd use a view binding library (e.g. React Redux) rather than subscribe() directly.
// There may be additional use cases where it's helpful to subscribe as well.
store.subscribe(() => console.log(store.getState()))
// The only way to mutate the internal state is to dispatch an action.
// The actions can be serialized, logged or stored and later replayed.
store.dispatch({ type: 'counter/incremented' })
// {value: 1}
store.dispatch({ type: 'counter/incremented' })
// {value: 2}
store.dispatch({ type: 'counter/decremented' })
// {value: 1}
```
//typstfmt::on
#subsection("React-Redux")
- library to combine react and redux
- mapping of react props to redux states
- dispatch actions to redux store from react
- components need to rerender on change
- therefore have multiple stores etc, so that only select components rerender
#subsubsection("(Deprecated!) Get data from react to redux (Deprecated!)")
//typstfmt::off
```js
// only template
// mapStateToProps: (state) => props
const ConnectedDashboard = connect(mapStateToProps)(Dashboard)
// call mapstate, which is just a function -> maps dashboard components state to connectDashboard -> which are props
```
//typstfmt::on
#subsubsection("Redux-Toolkit")
- standard for redux-react
- easy integration of redux into react
- usage
- create reducers and actions via *createSlice*
- initialize stores via *configureStore*
- embed stores into react root-components via *Provider*
- Dispatch of actions via *useDispatch*
- Access to state of objects via *useSelector*
- AsyncThunk
- npx command to create a new redux-toolkit template:
//typstfmt::off
```sh
npx create-react-app hello-ost --template redux
```
//typstfmt::on
#subsubsubsection("createSlice")
#text(teal)[creates state objects, reduce-functions and actions in one step.]
//typstfmt::off
```js
const balanceSlice = createSlice({
name: "balance", // action name
initialState: { value: 0 },
reducers: {
transfer: (state, action) => { // name is transfer -> action/transfer
state.value += action.payload.amount; // payload.amount needs to be set when creating an action
},
},
});
export const {transfer} = balanceSlice.actions;
```
//typstfmt::on
#set text(teal)
- transfer reducer can now be used in components
- "balance/transfer" is the actiontype
- state is immutable -> we do not update the actual state, that will still be done according to redux -> create new tree
#set text(black)
#subsubsubsection("configureStore")
Initializes the redux store with reducers.\
Default initialization contains:\
- redux-thunk for async actions
- redux dev tools
//typstfmt::off
```js
import { configureStore } from "@reduxjs/toolkit";
import { balanceReducer } from "./redux/balanceSlice";
const store = configureStore({
reducer: { balance: balanceReducer}
});
export default store;
```
//typstfmt::on
different file:
//typstfmt::off
```js
import store from "./store";
// makes the store usable in this component and it's children
render(
<Provider store={store}>
<App />
</Provider>,
document.getElementById('root')
)
```
//typstfmt::on
#subsubsection("useDispatch")
Used to dispatch actions to the store. Store then runs reducer functions on the state.
```js
import { useDispatch } from "react-redux";
const dispatch = useDispatch()
// ...
// create a new action and push it to the store
// note according to the action defined in createSlice, the action needs the amount value
dispatch(transfer({ amount: 10 }))
```
#subsubsubsection("useSelector")
Used to get values of the state.
//typstfmt::off
```js
import { useSelector } from "react-redux";
// get the value variable from the state with name balance
// note that the name is a string -> not a variable in createSlice
const balance = useSelector(state => state.balance.value);
```
//typstfmt::on
#subsubsubsection("Async actions")
- made possible with Redux-Thunk, which is a middleware
- configured automatically with configureStore
#align(center, [Create slice])
//typstfmt::off
```js
const balanceSlice = createSlice({
name: "balance", // action name
initialState: { value: 0, status: "idle" },
extraReducers: (builder) => {
builder
.addCase(transferAsync.pending, (state) => {
state.status = "loading";
})
.addCase(transferAsync.fulfilled, (state, action) => {
state.status = "idle";
state.value += action.payload.amount;
});
},
});
```
//typstfmt::on
#align(center, [Use reducer])
//typstfmt::off
```js
import { createAsyncThunk, createSlice } from '@reduxjs/toolkit';
import api from "./api";
// First, create the thunk
export const transferAsync = createAsyncThunk(
"balance/transferApiRequest",
async (amount) => {
// function transfer is a reducer!
const response = await api.transfer(amount);
return response.data;
// note the data
}
);
// ...
dispatch(transferAsync({ amount: 10 }))
```
//typstfmt::on
#subsubsubsection("example")
//typstfmt::off
```js
import { createSlice, configureStore } from '@reduxjs/toolkit';
const counterSlice = createSlice({
name: 'counter',
initialState: {
value: 0,
},
reducers: {
incremented: (state) => {
// Redux Toolkit allows us to write "mutating" logic in reducers. It
// doesn't actually mutate the state because it uses the Immer library,
// which detects changes to a "draft state" and produces a brand new
// immutable state based off those changes
state.value += 1;
},
decremented: (state) => {
state.value -= 1;
},
},
});
export const { incremented, decremented } = counterSlice.actions;
const store = configureStore({
reducer: counterSlice.reducer,
});
// Can still subscribe to the store
store.subscribe(() => console.log(store.getState()));
// Still pass action objects to `dispatch`, but they're created for us
store.dispatch(incremented());
// {value: 1}
store.dispatch(incremented());
// {value: 2}
store.dispatch(decremented());
// {value: 1}
```
//typstfmt::on
#subsubsection("When to use Redux")
- when multiple components need to access state
- when state is unreasonably big for one single global state
- e.g. this has overhead and said overhead needs to be valuable

== Réseaux de neurones (forward propagation)
Nous pouvons facilement constater qu'une couche d'un réseau de neuronnes ainsi que la fonction d'activation peuvent être représentés comme des fonctions sur des vecteurs (de deux dimensions). Un réseaux de neuronnes n'est seulement qu'une suite d'application de fonctions. Par exemple le passage d'un vecteur sur un réseaux de 3 couches serait représenté comme ceci:
#Exemple()[Combinaison de fonction à l'aide de système C3PO
```R
let couche1: type = ... in
let activation1: type = ... in
let couche2: type = ... in
let activation2: type = ... in
let couche3: type = ... in
let activation3: type = ... in
activation3(couche3(activation2(couche2(activation1(couche1(v))))))
```
]
Heureusement, il existe plusieurs solution syntaxique qui nous permettent de facilité la lecture d'un tel réseau. Ces solutions ne font pas directement partie du noyaux du projet mais permettrait une implémentation plus concrète du typage de réseaux. La notion d'appel de fonction uniforme qui nous permet d'avoir une représentation plus lisible à l'oeil humain à l'aide de tuyaux:
#Exemple()[Combinaison de fonction à l'aide de tuyaux
```R
v
|> couche1
|> activation1
|> couche2
|> activation2
|> couche3
|> activation3
```
]
Pour les personnes plus adepte du passage par message:
#Exemple()[combinaison de fonction à l'aide de passage de message
```R
v
.couche1()
.activation1()
.couche2()
.activation2()
.couche3()
.activation3()
```
]
Ces deux exemples seront transformé pour donné le premier exemple durant la compilation. Cela nous permet plus de flexibilité dans la notation. Non seulement nous sommes capable de représenter les réseaux de neuronnes de façon plus simplifié, mais nous avons aussi la garanti de contrôl au niveau de la compatibilité d'application de ces fonctions. Si la sortie d'une de ces fonction ne correspond pas à la sortie de la suivant, le compilateur sera en mesure de détecter ce problème. Cela permet donc de cérer des réseaus de neuronnes de plus grande envergure de façon plus intrépide.

Shielded within the hedrons that had grown up over the bones of Ugin, Naiva knelt beside her twin sister, holding a knife to her throat. Baishya was lost to a whisperer's trance, eyes closed, fallen deep into a vision Naiva could only share if she was touching Baishya's bare skin with her own. Magic lived in her twin and was denied to #emph[her] . Envy and anger gnawed at her guts until she was nothing but jagged splinters.
Why was she constantly told she had to protect her twin? Wasn't Baishya nothing more than a burden and a danger to the tribe? It would be better if her sister were dead. Then she wouldn't be treated as the lesser one ever again because she would be the only one. And in the years to come, people would forget Baishya had existed at all; they need never know Naiva the great hunter had ever been a twin.
A thin line of red welled up along the curve of her sister's neck.
Yet as Naiva breathed, struggling with the harsh thoughts, a stillness slowly expanded inside the troubled waters of her heart. The Spirit Dragon's essence pressed in upon her, clear and sharp, severing the thread that linked her to the cruel voice slashing venom-laced chasms into her mind. Her gaze dropped to where a knife was clutched in her hand. Why was she holding a blade against her sister's throat?
"What are you doing!"
A strong hand snatched the knife out of her fingers and flung it aside. It thunked hard against the wall and hit the dirt with a thud.
Blinking in confusion, she turned to see Grandmother awake and aware. Yasova grabbed Naiva's chin and forced her gaze to meet her own.
"What is your name?" Grandmother demanded, examining her eyes.
"I'm Naiva," she said indignantly, pulling back. "Have you already forgotten me?"
"Of course I have not forgotten you. I cut you two out of my daughter's dead body with the knife you were holding to your sister's throat. Why did you not go up to the sanctuary, as I told you?"
"There was someone on the path~Mevra~no~a dragon~that can't be~" She rubbed her eyes. Already the events just passed seemed hazy and unreal, like a story she'd heard years ago and could not quite recall.
"He found you." Grandmother studied the cocoon that enclosed them. "The hedrons protect us from his touch."
"I don't understand."
"The dragon who killed Ugin has returned."
Her thoughts dredged into the sluggish deeps, hauling a name to the surface. "<NAME>."
"Yes. He uses his touch to manipulate the thoughts and emotions of others. Did he tell you to kill your twin?"
Her head began to ache. When she squeezed her eyes shut, pale ghostly shapes floated as if trying to form into a coherent memory. "I don't remember~no, no, wait. I am supposed to bring you, Grandmother. He wants you."
"He will get me."
"You can't go out there! He'll kill you."
"That's likely."
"So we'll just stay safe in here until he grows bored and goes away."
"Do you think he's as easily distracted as one of Atarka's broodlings? Because he is not. What do you think will happen if he does not get me?"
"He threatened to destroy Tarkir. Can he do that?"
"He killed Ugin by turning the minds of all the dragons against their own progenitor. He's a Planeswalker, ancient beyond measure. So yes, I must assume he can destroy Tarkir if he decides to do so."
"What have I done?" Tears of shame ran down her cheeks. "I never meant to betray you, Grandmother."
"You betrayed nothing. Yet for all I have tried to teach you girls, you have not listened well enough. Understand this. Any one of us may die at any time, and we will all die eventually. What matters is that we have woven threads to connect ourselves to the past so we do not forget our ancestors and what they have to teach us."
"I'll go out and say I couldn't find you!"
"He will kill you and turn his wrath upon Tarkir. If our people are to survive we must outwit him." She studied Baishya's closed eyes and serene expression. "Perhaps this is why Ugin summoned us."
"Ugin is dead."
"Yes. Ugin is dead. He cannot speak to us in the ordinary way. He cannot even speak through the Whisper Mind."
"How would Ugin know about that?"
She raised an eyebrow. "He taught the skill to the shamans among our ancestors."
#figure(image("008_Chronicle of Bolas: The Unwritten Now/01.jpg", width: 100%), caption: [Shaman of Forgotten Ways | Art by: <NAME>], supplement: none, numbering: none)
"He must have learned mind-speaking from Bolas," Naiva muttered angrily. "Why should we trust the Spirit Dragon? He could have been manipulating us all this time too, couldn't he?"
"He taught different secrets to the other tribes."
"Like the ghostfire?"
"Yes. By sharing his secrets among the clans, no one clan would have more power than the others. What did Bolas offer you in exchange for bringing me to him?"
She shrugged, too ashamed to reveal the words he had said, and the horrible things she had thought. "I didn't know I was so weak."
"You are not weak. His power is vast. I intended to tell you and your sister the full story when you came of age, but it seems you have met your challenge now. So listen carefully. Years ago, before you were born, I helped Bolas track down Ugin because he promised me an end to dragons on Tarkir. To my shame, I even cast a spell that helped him turn the minds of the fledgling dragons against Ugin. It's important you know the truth, that I was promised the thing I wanted most—the end to all dragons—and I gave in to it. Only afterward did I discover the promise was a lie. Am I weak?"
"No!"
"Then neither are you."
Baishya slumbered in her trance, untouched and tranquil. A surge of knotted envy twisted through Naiva's gut; she was glad Baishya was spared this terrible scene, yet why was her twin always the one to be spared the crude emotions and turmoil of life?
"Ah. I see what he promised you. You resent your twin."
"I love her!"
"Yes. It's possible to both love and resent someone at the same time. But you two will always be bound, no matter what happens."
Naiva scrubbed tears from her cheeks, hating how they made her feel. "You were holding her hand. Did you see the vision? The water and the popping bubbles?"
"No, I did not. Your nature as twins must give you a window into whatever she is seeing."
"What is she seeing, if Ugin is dead? Or is he just sleeping?"
"His bones tell us he is dead. Yet his essence is contained within these hedrons. He is the soul of Tarkir. That must be why shamans can communicate with the part of him that is rooted in Tarkir, even if he is dead. Just as we have our ways of communicating with the ancestors."
"Why does that matter to us? Why not let Bolas have what he wants so he'll go away?"
"I do not believe Bolas can destroy the hedrons. Even if he can, if he destroys the hedrons, then the essence of Ugin will be obliterated. If his essence is destroyed, then even if the rock of Tarkir remains, it will no longer have a soul. That will be the death of our people and all of Tarkir. Even the dragons. As much as I hate the dragons, I love my people more. I do not want them to perish, even if it means saving the dragons."
#figure(image("008_Chronicle of Bolas: The Unwritten Now/02.jpg", width: 100%), caption: [Crucible of the Spirit Dragon | Art by: Jung Park], supplement: none, numbering: none)
Naiva gazed on her sister's face. Baishya's expression was peaceful, but the rapid movements of her eyes gave away that some part of her mind was active.
"The bubbles are memories," Naiva said.
"Take Baishya's hand again. Find out what Ugin is trying to tell us."
Naiva did resent Baishya and her magic and her strange surety of purpose, both dynamic and mysterious. For years, she'd felt as if people thought her lesser because she was only a hunter, and there were plenty of hunters, while whisperers were rare and thus precious. She'd pretended not to envy her. It was a relief to have the sour envy dragged into the open, even as repugnant as it was. Beneath the sheltering hedrons, no claw from Bolas's mind could rend her heart. However annoyed she often was at Bai, she didn't want to imagine the world without her in it.
She smiled at her sister's face, twin to her own, the mirror she'd looked into for all of her life. After a decisive nod at Grandmother, she took hold of Baishya's hand. The world around her fell away as the glittering cliffs of Ugin's dormant mind bound her.

The landscape is a silvery sheet of water as flat and reflective as a mirror extending to the horizon on all sides. Here and there, rocky islands like spires rise from the endless sea, each creating a perfect resting place on which to meditate.
No wind stirs the air, yet glimmering, translucent globes float like bubbles caught in a breeze that touches nothing else.
One of these globes drifts close, and closer yet to the dreaming shadow of the girl asleep atop the waters. When its frail surface touches the edge of her misty form, it pops. The thin sphere of liquid spills memory into the shadow of her mind.
#v(0.35em)

A dragon hovers over the still waters, staring into its reflection, a mirror which looks back on itself. The reflection is so complete in every detail that it might be the original dragon looking into a mirroring sea, and the dragon floating aloft might be its reflection, complete in every detail.
Although this realm is perfectly created for meditation, although he has rested here for long periods to contemplate mystery and eternity, Ugin cannot calm his turbulent thoughts now. He'd been so sure Nicol would be overjoyed to see him, would want him to share the wondrous details of his fascinating journeys through the planes. But he'd judged wrong. Or maybe he had only misjudged himself.
He should never have left the birth mountain, yet he hadn't fled Dominaria on purpose. The spark had taken him unawares. It had flung him outward like a fish hooked and hauled out of the water, the only home it had ever known, to be thrown onto unfamiliar shores. He hadn't understood what happened until he'd landed on Tarkir, and then the sense of belonging and connection he'd felt for Tarkir had kept him preoccupied for far too long.
#figure(image("008_Chronicle of Bolas: The Unwritten Now/03.jpg", width: 100%), caption: [Seek the Horizon | Art by: <NAME>], supplement: none, numbering: none)
Was he at fault? Or was it just the way things had fallen out? Maybe if he'd stayed, events would have unfolded in the same way. Nicol had succumbed to the worst in himself, and now, he intended to inflict his power and anger upon all of Dominaria.
Regret for what Dominaria would suffer as the dragons went to war with each other battled with the relief that Nicol was stuck there. Unable to planeswalk, he could never impose his terrible vision of law and justice on the rest of the planes. That was something, at least.
A bright flash like the rising of a second sun spills a splash of gold across the still waters. A howl of rage sunders the peaceful silence.
A huge body falls like a stone flung out of the heavens. Just before he hits the water, <NAME> spreads his wings and rises. He shines as brightly as the sun, and ire is his color.
With a howl on the wind and a searing blast of fire, he dives murderously toward his brother. Ugin stares, bewildered by the abrupt attack, thinking at first it might be an excess of joyful celebration. Only when the stinging sparks of Nicol's fire wash over his head, blistering his eyes, does he shear to one side. His right wing skims the water's surface, cutting a gash through his own reflection. He rights himself, leveling out, and races away toward the archipelago of islets. Nicol pursues. His fury grants him a strength and speed that weary, sorrow-ridden Ugin lacks.
Fire burns at Ugin's rear claws. A wash of caustic magic like a cloud of venom numbs his hindquarters. He dodges in among the islets. He's explored here often, rested upon these craggy outcrops under the silvery sky and its placid moons. He knows just where to twist and turn, leaving Nicol to overshoot with a bellow of anger and clumsily turn around.
But Nicol figures out the game quickly. He changes tactics, ascending so he can spot Ugin from above with no rocky obstacles in his path.
Ugin's shout carves waves into the water as if it has become a powerful wind. "Nicol! What do you mean by attacking me?"
"You hoarded the knowledge of the planes to yourself. You lied to me. You taunted me with a vision of the treasure you had discovered, and then you spitefully abandoned me."
"I came back for you—"
"You never came back for me. You only returned to mock me because you couldn't be content unless you were sure I would suffer for eternity knowing you had won a prize I could never touch."
"That's not true. I didn't know—"
"Of course you knew."
Nicol plunges toward the water, claws out. As Ugin dodges, he raises a dense fog off the water to conceal his movement. Nicol drags a furrow through the water, and waves ripple in great swells outward then slowly quiet as Ugin considers what to do.
Wingbeats carry Nicol aloft again. He begins to circle as the haze slowly dissipates. "Ugin! Don't be too much of a coward to admit your treachery. I'll have my revenge either way."

Ugin has traveled through the Multiverse with the greatest curiosity, observing as he goes, recalling the lessons of Te Ju Ki and the example of <NAME>huell. He has learned the magic of discovery, of investigation, of discernment, and even of defense. What he has taken no time to learn is the magic of attack and assault. He would always prefer to talk rather than fight, to build rather than tear down. He cannot win by copying Nicol's aggression. Only shrewdness, and a bit of dragon trickery, can save him now.
"How did you gain the spark?" he asks, because knowing why may help him understand what Nicol has become.
"The spark you meant to withhold from me?"
"I could never have given you the spark. I did not seek it. It came to me unbidden."
"So you claim, but I don't believe you. And now the spark is mine. I will not share it with you. I will not share the planes with an enemy who betrayed me."
"I am not your enemy—"
Nicol dives again, silent and determined.
Ugin takes the only path left open to him, even if it means Nicol will brand him a weakling and a coward for it. He walks out of the Meditation Realm and through the darkness to drop into storm-wracked Zendikar. Within the tumult of clouds, he glides on the storm winds, sure he can at least catch his breath and think about what to do next, how to escape until Nicol calms down, how to negotiate, how to convince his twin that it was ignorance and not malice.
But Nicol is right on his tail, bursting into the darkness in a flash of golden light. Again, Ugin walks, and again, seeking a plane that will conceal him just for a short while. From bustling Kephalai to growing Ravnica and on and on, he flees with Nicol breathing down his neck, never slackening in his pursuit.
It's growing harder for Ugin to see as his blistered eyes develop pustules, as the numbness creeps up his extremities from the magic Nicol wields. He'll heal in time. Dragons have that gift. But he cannot rest, he cannot eat, he can do nothing but run. As he races to stay ahead of Nicol's unquenchable animosity, he begins to feel his wounds eating away at his strength.
Yearning flashes: he could return to Tarkir, hide where his soul feels at peace, where the world welcomes him and wishes to heal him. But then Tarkir itself becomes vulnerable to Nicol's rage. He would rather die than let Tarkir be wantonly destroyed, and if anyone would commit such a vile, remorseless act, Bolas would.
As the thought washes over him, he sees in his mind's eye the still waters of the Meditation Realm. He sees himself reflected in that liquid mirror, down to every detail. What is the Meditation Realm, really? It's a mystery he has yet to fathom.
Te Ju Ki's wise words sweep over him as a breath of warm wind, with a perfume that calms his tumultuously beating hearts.
#emph[Doesn't death scare you?] he had asked her. And she had answered:
#emph[My essence will continue to exist in other forms. All things end. Sometimes that is not the same as dying.]
He knows what he must do. Nicol will never stop pursuing him, not unless he thinks his twin is dead.
He planeswalks back to the Meditation Realm, where he waits, floating above the still waters, or perhaps his reflection floats, looking down on himself. He is exhausted yet buoyed up by new strength, by a surety that he will reject what Nicol has become.
#figure(image("008_Chronicle of Bolas: The Unwritten Now/05.jpg", width: 100%), caption: [Pools of Becoming | Art by: Jason Chan], supplement: none, numbering: none)
In a burst of light, Nicol appears high in the lustrous sky. He dives, all teeth and claw. In a flash of comprehension, Ugin sees how malevolence is threaded through his twin's entire being. Maybe it was only a tiny seed within him, long ago; maybe Ugin leaving allowed it to thrive and flourish. The brother he was born with, whom he flew with—Nicol—has been entirely devoured by Bolas, the name Nicol gave himself because he could only measure himself against others. Maybe nothing Ugin could have done would have changed this outcome. But he regrets that it has come to this.
With a sigh, Ugin accepts his death. He lets go.
Bolas roars in triumph as his magic billows in a steaming cloud around his hated foe, as his claws slice deep into his enemy's hotly beating hearts, as his teeth slash his rival's unprotected throat.
With a mighty splash, Ugin falls into the still waters. The impact resounds like thunder. Monstrous waves rise from the displacement and sweep across the craggy islets, crashing and destroying the ancient rocks. The disturbance washes far beyond the bounds of the Meditation Realm, spilling into the fathomless dark cavity whose infinite web connects the planes themselves. The sea empties, exposing the rock of the seabed like bones left to bleach in the sun.
Dragged by the sheer shocking force of the cataclysm, Bolas flares like a sun and vanishes, torn away to the plane of his birth, falling to the islands of Madara.
Where once the realm was filled with the silence of tranquility, now it is vacant. It has become a wilderness of rock, barren and wrecked, all its serenity drained away into the interstices of the blind eternities, a chasm that can never be filled.
Nothing moves because nothing remains.
A moment passes. A year. A generation.
A millennium.
Or maybe, no time at all.
A pale sheet of liquid trickles up as out of nowhere, returning from the unseen and untouchable web of darkness. With eerie silence, it inexorably rises, refilling the realm with its silvery waters. When the waters cease rising, they grow still, and in that still mirror waits the reflection of the dragon.
He inhales, pulling the waters into himself. They curl and froth into every crevice and wrinkle and scale and indentation until his horns sparkle and his claws gleam and his eyes shine with magic. Is he flesh and bone, or is he spirit and magic? Does it matter?
The dragon floats above the dry seabed beneath the luminous sky.
He sweeps his gaze across the fractured realm and its barren, broken landscape. This manner of destruction is the promise Bolas has made; it is what Bolas wants for anything or anyone who defies him. Someone must stand against him, someone who knows him well enough to defeat him. And Bolas is not the only threat against the Multiverse.

Ugin has a lot to do if he means to protect the planes.
On a ripple of invisible flame, he departs.

The dry seabed lies quiescent, empty.
Bubbles begin to swell up one by one from the rock itself. One by one, they pop. The liquid of their surface slides into the hollows and depressions on the empty seabed, and slowly—oh-so slowly—the Meditation Realm begins to fill up again with lost memories.

In the Meditation Realm, the god-emperor perches atop an outcropping of rock amid the ruins of a once handsome temple whose columns and roof were dashed to the ground at the time of the cataclysm. To Bolas, these marks of devastation are marks of victory. His wings, outspread, cast a shadow over the waters. He can't quite recall exactly where Ugin fell, but fall he did, and now the opaque waters have become his grave.
This, the site of his greatest triumph, is a fitting place for him to ruminate over his plans. To give himself a focal point on which to center his meditation, he chooses a spot at the center of a vast span where no islands break the surface. Here, he erects two gigantic curved horns so they emerge from the waters as if a gargantuan dragon lies sleeping beneath, body hidden from sight. When he is done, the sky gleams with a contentment that matches his own.
Yet a nub of discontent chafes against his satisfaction. Shred by shred, the mask of victory peels apart to reveal the seed of rancor beneath. Not all of Dominaria cowers beneath his rule. He has enemies unwise enough to believe they can defeat him. Besides that, so many planes await his presence. How is he to grace them all with his magnificence? How is he to prove that he is not the least, that he was first, best, always?
The challenge arises before him like the cliffs of a towering mountain, like the vast immensity of a planes-spanning chasm, like the teeming swords and spears of a world-slaughtering army. The insatiable maw of his ambition will devour them all.

In a great city of glass and stone, a winged creature with the bearded face of a man and the graceful paws of a big cat greets the Spirit Dragon.
"Ugin, my friend, welcome to my newest home. What brings you to this plane?"

"When last we met, we discussed our common foe. Every world is in danger, as long as our enemy is free and whole. That is why I am here. I have devised a plan to rid the Multiverse of his influence, but I cannot do it without you."
"To capture him and trap him, you will first have to lure him to a specific location."
"I will lure him to Tarkir."
"Is the plane of Tarkir not your soul's home? Does such a scheme not place Tarkir itself in danger?"
"That is why he will come and not suspect anything. He believes I would never risk Tarkir."

The Spirit Dragon soars amid a tempest, thunderclouds surging around him as the winds boom and bluster. He is waiting. A flash of light heralds the arrival of <NAME>, his curved horns now embellished with a gem floating between them like a third eye that sees only what he lacks, what he does not yet possess.
The two elder dragons face off, circling as the storm creates a funnel of raging winds around them. They are well-matched, one armed with cunning and the other with wisdom. The Spirit Dragon knows it is impossible to kill Bolas outright. That is why he has devised this elaborate plan with his ally: their only chance is to trap their foe so he can never planeswalk again. To do that, he must hold Bolas here on Tarkir until the magical device can be activated.
With a roar, he wakens the force of Tarkir's soul. Dragons pour in from all across the plane in answer to Ugin's call. Even with this advantage in numbers, the Spirit Dragon does not attack. This is all a feint, to lure in Bolas, to make him forget to be cautious.
Yet even the best laid plans may crack. Bolas turns the dragons of Tarkir against their own progenitor, and when his enemy has been weakened by their attacks, he breaks Ugin's body with a deathblow. The Spirit Dragon plummets to the ground. The force of his impacts smashes a chasm into the rock that alters the landscape. The reverberations of the destruction will roll on for years and generations and millennia throughout the Multiverse.
Victorious, Bolas vanishes in a burst of light.

Naiva jolted upright.
"Ouch! Let go!" Her sister shook off Naiva's hand and rubbed at her shoulder. "It's like you scratched my heart!"
"Did you see it?" Naiva demanded.
Baishya rubbed her face, shook herself, and let out a sigh. "I saw into an ocean of memories. Did you see it too, Nai?"
"Yes. Through you."
Grandmother was still seated cross-legged, watching intently. "Tell me."
Speaking in a rush, one picking up when the other paused to catch her breath, the two girls described what they'd seen. When they finished, Grandmother considered in silence for a few breaths, turning over what they'd said. Then she nodded in her decisive way.
"The Spirit Dragon has not forgotten Tarkir. We have a chance to deflect Bolas. One desperate chance. I will take it."
#figure(image("008_Chronicle of Bolas: The Unwritten Now/08.jpg", width: 100%), caption: [Ugin, the Spirit Dragon | Art by: Raymond Swanland], supplement: none, numbering: none)
"Do you mean to surrender yourself to him?" Naiva demanded.
"I do."
"But he already manipulated you once."
"Yes, so I am prepared this time. I won't be as vulnerable."
"What if he kills you?" Baishya asked, voice cracking as she clutched at her grandmother's hand.
"I don't fear dying. I helped bring this about, so it's proper I help end it."
Naiva pulled her twin's hand away from their grandmother. "You'll stay in here, Bai. You have to stay safe because who else can communicate with the Spirit Dragon?"
"No," said Grandmother. "Bolas got his claws into you, Naiva. I do not blame you for it, but Baishya will wear your mantle and go out in your place."
"What difference will that make? If he invades her mind or your mind, he'll see it's not me."
"Maybe. But he's arrogant. And he's never seen Baishya, so he may not believe he needs to probe any deeper since he surely believes he controls you. It's a chance we have to take."
"I can do it, Nai," said Baishya. "The second thing a whisperer learns is how to deflect magic."
"He's too powerful. He'll kill you both."
"She need only deflect his touch long enough to sow a seed of doubt, just as her wearing your mantle will ease his suspicion," said Grandmother.
"And the hedron shield will offer a little protection, like an extension of a whisperer's headdress," added Baishya.
"Yes," agreed Grandmother. "Now do as I say."
Naiva took in a calming breath and released it with a hiss blended of frustration, anger, fear, and resolve. The girls swapped mantles.
Grandmother examined them. "It's fortunate you wear your hair the same."
"Wait." Naiva pulled off the necklace she wore, threaded to the tooth of a bear she'd killed when she was sixteen, and draped it over Baishya's neck. Then she hugged her sister. Fear had lodged beneath her ribs like a spear point, but now that the decision was made, her mind could fix on the hunt. She handed over her spear. Grandmother and Baishya crawled out through the low opening, leaving her behind in the tent-sized space entirely enclosed by the walls of the rock cocoon. Their footsteps scraped on the dirt as they walked forward.
She could not bear waiting in ignorance, so she knelt beside the opening, adjusting her position so she could peek out without being seen from outside.
Grandmother and Baishya stood in the shadow of the dragon. One huff of fire, one swipe of claw, one blast of magic would easily kill them, yet they did not cringe or grovel.
No listener could mistake the gloating rumble of the dragon's words.
"Yasova Dragonclaw. You have served me well."
"And you, <NAME>, you have acted exactly as the Spirit Dragon knew you would." Grandmother flung her spear of words without hesitation. "You think you're the deceiver, but he deceived you."
The shadow rippled as the dragon moved restlessly. In a sharper tone, he said, "What do you mean?"
"You came back to see if he was really dead."
Sparks flashed along the ground in a warning cast of deadly rain. "Of course he is dead. I killed him."
"The last time you thought you killed him, he tricked you. I am here to tell you he has tricked you again."
"Why do you lie?" the dragon cried. "I saw him fall! I saw his body hit the ground. Your own granddaughter confirmed it. Little Naiva, is it not true? Ugin is dead!"
#figure(image("008_Chronicle of Bolas: The Unwritten Now/09.jpg", width: 100%), caption: [Tomb of the Spirit Dragon | Art by: <NAME>], supplement: none, numbering: none)
"If you're so sure Ugin is dead, why #emph[did] you return to Tarkir?" said Baishya in her most scornful voice, the one that usually annoyed Naiva out of all reason. Hearing it turned on a stupendously powerful Planeswalker, who could obliterate grandmother and granddaughter with the merest touch of magic, made her appreciate her twin's quiet but sharp courage, so different from her own brash boldness. Yet who was the bold one now? Not Naiva, hiding inside the cave-like space within a hedron while others faced down the dragon.
Baishya went on in the same goading tone. "You can't admit you came back to make sure he was really dead #emph[this] time, after he tricked you last time."
The shadow ripped away, vanishing as the dragon flew. Naiva dropped flat on the ground, craning her neck so she could see the sky and the canyon walls. His physical form had vanished from view, but his magic erupted in a crackling display of lightning high above followed by four massive booms of thunder. A magical wind blasted down from on high, forcing Grandmother and Baishya to their knees. The hedrons shuddered beneath the gale. The wind was so strong that the scale-like oval of thin rock they'd used before to cover the opening was slapped sideways to block Naiva's view, leaving only a finger's-width gap to let in light and air.
As suddenly as it rose, the gusting wind died. A darkness spread over the ground with the great dragon's return. Though she could not see him, every fiber of her being felt his massive, malevolent presence like a claw at her throat. She tried to take in a breath but choked instead on a venomous and consuming terror. She would lose them both. If she ran out now, she could strike at him, distract him while the other two ran for the safety of the hedrons. She'd be the bold one, the fierce hunter, just as she'd always known should be her rightful place in the tribe.
She pushed up into a crouch, readying to shove the slab aside and cast herself against the foe.
Instead, she paused, forcing herself to breathe more slowly.
Maybe Grandmother feared that even with the protection of the hedrons, Naiva was too weak to be trusted. Or maybe the fear that her beloved grandmother didn't value her was her own weakness speaking, a foe only she could defeat. She had to trust the woman who had raised her, who had saved the Temur people from Atarka's wrath.
Hands clenched, she focused her thoughts. However hard it was to do so, she had to accept that her part in today's hunt was not to throw the spear but to remain concealed.
As the great dragon exhaled in anger, a wash of stinging heat swirled through the narrow crack and into the tiny chamber beneath the hedrons. "Do not toy with me. I can kill you both in an eye blink. After that I will jubilantly devastate Tarkir until not even the slightest bug crawls upon its blighted surface."
"Then get on with it instead of boasting," replied Grandmother in her usual brusque tone. "Kill us if you will, raze and ruin Tarkir if you choose, because it makes no difference to Ugin's plan. There will always be a greater power than the one you wield."
"I am the greatest power!" His voice boomed, cracking rocks. "As you'll soon see, <NAME>, when your own beloved granddaughter drives a knife into your heart. Do it, Naiva. I command you! Kill her, and I will grant you all that you desire, dominion over this world to become your private hunting grounds. You will be first and best, always."
The words drove into Naiva's heart as a secret and poisonous wish. First and best, always. Grandmother should have been training her to become leader after her instead of wasting her time on Baishya and the other shamans. Their path was dead, like Ugin. It ought to be dead, and she could kill it once and for all.
She need only shove aside the slab of rock and crawl out. Baishya had never been as physically strong, so it would be easy to wrestle the knife from her sister's hand. She would press the knife against Grandmother's throat, feel the thunder of her pulse, the vulnerability of her beating heart.
The great dragon sucked in an expectant breath. His pleasure in watching love turn to hate, loyalty into betrayal, spread like a devouring heat over the scene.
Her fingers touched the grainy rock shield, ready to shove it aside.
Baishya's voice slapped her like a chilling wind. "Maybe I don't want to hunt. Maybe nothing you offer tempts me, because from everything I've heard, you're stuck in the past, circling around and around your rivalry with Ugin—"
#figure(image("008_Chronicle of Bolas: The Unwritten Now/10.jpg", width: 100%), caption: [<NAME>, the Arisen | Art by: <NAME>], supplement: none, numbering: none)
"I'm not stuck!"
"You're about to be," Grandmother interrupted curtly.
Naiva pulled her hand back, teeth gritted as she struggled against a ferocious desire to charge forward. For the plan to work, she had to stay concealed. She had to.
"You're standing right where the hedrons concentrate magical force into a nexus of great power," Grandmother went on. "The Immortal Sun is pointed here, at this very spot on Tarkir. It will drag you to another plane and, there, trap you for all eternity. Why do you think we've kept you talking all this time? So it can be activated, and you'll never planeswalk again."
If he was torn from Tarkir, he could not make her first and best among hunters. Only she could stop them, and only then could she get what she had always wanted, what she deserved. Again, she pressed a hand, fingers spread, against the slab's smooth surface, ready to shove it aside. A cooling pulse of calm raced down her arm. Its steadying vibration bled a harsh light into the depths of her soul.
It was a child's petty, selfish desire that drove her. She was better than this. She would be better than this. Shaking, she closed her hand into a fist and tucked it against her throat as she swallowed the rancid flavor of her resentment and envy.
Outside, as if in reaction to that unseen movement, Grandmother inhaled audibly, as if in anticipation and suspense. "Ah! Listen! Do you hear the artifact's hum, Naiva?"
"I hear it!" cried Baishya in the falsest tone Naiva had ever heard, but how was the dragon to know that when he couldn't even tell the twins apart? "Just as Ugin said it would happen! Look up above! Do you see the light? A second sun in the heavens!"
A roar of fury rattled the hedrons. Shaken loose, the scale-like slab of rock tilted, teetered, and fell sideways to unblock the opening just as the vast shadow lifted. Boulders crashed down from the rim onto the open ground where Grandmother and Baishya stood. An avalanche of rock and ice pummeled the indestructible hedrons, splintering into shards that flew through the gap against Naiva's face to gash her cheeks. She tugged her twin's mantle over her head to protect herself. Dust boiled up to obscure the scene beyond until she could see nothing excepting a dizzying dark whirlwind that filled the world. He had struck, and those she loved most would be obliterated, and after them, all of Tarkir~and her with it.
The light outside changed color with a harsh golden flash that blinded her. Air swirled out of the opening, pulling the choking squall of dust back outside.
Somehow, she wasn't dead yet. Her heart still beat.
Slowly, in ominous silence, the particles settled. Her lips were annoyingly filthy, coated with a foul-tasting grit. The silence weighed horribly, like the end of all hope, the sick regret that it had taken so little for the dragon to manipulate her. Grandmother had been right about her weakness.
Yet still her heart beat. She had resisted Bolas's magic and stayed inside the hedron. Tarkir wasn't ravaged and broken.
Cautiously, she ducked down to peer out the opening.
Snow melted off the angled hedrons by the heat dripped onto the ground in little plops and ticks. She rubbed her burning eyes as the world's shadows and brightness gradually came back into view. Scraping her hands, she crawled outside over a sliding heap of broken rocks into a clearing half-filled with the deadly debris. The canyon walls rose solidly above her, watching over the untouched hedrons. The sky gleamed a brilliant blue, the sun blazing high overhead in magnificent indifference just as it did every sunny day.
The dragon had vanished. But she was alone.
Grandmother had saved Tarkir, but at the cost of her and Baishya's lives.
Staggered, she rocked backward, hitting the hedron wall. Her legs gave out and, helpless to stop herself, she slid to the ground. What had she done, stupidly cowering inside the hedron? Why hadn't she acted, flung herself at the dragon?
But she shook off the useless thoughts. The chance of death had been part of the plan. It wouldn't have worked otherwise. Yet she could not breathe, thinking of how she would have to walk forward through the world without her twin beside her. Her heart was ripped in two, but somehow, she had to stand up and find the others. Just not yet. She couldn't find the strength quite yet.
A faint scuff broke the silence. It sounded exactly like a foot shifting on the dirt, but there was no one but her in the clearing, just a heap of huge rocks. Someone coughed.
Jolted by adrenalin, she jumped up with knife in hand. A big boulder shifted with a great, grinding rumble. It crunched sideways to reveal Grandmother and Baishya standing, alive, in a tiny pocket of space made by several boulders packed together. A powerful glow of magic faded from her twin's outstretched arms as Baishya slumped forward.
Scarcely able to breathe for the dust in her lungs and the hope choking her heart, Naiva scrambled recklessly over to them, scrabbling and sliding on loose rock until she reached the patch of untouched ground. She caught her twin around the back, holding her up. Her twin was warm. Breathing.
"You used your magic to hold off the rocks!" she cried, because it was the only thing she could think of to say. Tears cut trails down her dust-smeared, blood-streaked face.
#figure(image("008_Chronicle of Bolas: The Unwritten Now/11.jpg", width: 100%), caption: [Temur Runemark | Art by: <NAME>], supplement: none, numbering: none)
"Is he gone?" Baishya whispered, leaning trustingly against her sister.
"He's gone," said Grandmother. "He could not take the chance it was a bluff."
"I was sure he'd killed you!" Naiva started to shake as the full import hit her. Baishya: dead. But not dead. She was #emph[alive] . They had survived.
"It was a risk," agreed Grandmother. "But he knew that if I was telling the truth, then even taking the time to fly down to swat us with his own claws might have been too late for him. I believe he was sure the avalanche created by his departure would kill us."
"And you were telling the truth in a way," said Baishya. "There #emph[was] a plot to trap Bolas using the Immortal Sun. Except Ugin died before he could set it in motion."
"Is the Spirit Dragon really dead?" Naiva studied the unmarked surface of the hedrons, thinking of the vivid fullness of the memories the girls had shared. How was it possible that recollection could pass from the dead to the living so strongly?
"All things end," said Grandmother. "Sometimes that is not the same as dying."
A crack of sound brought their heads up. Loosened rock broke off the lower canyon wall and slid noisily down the hedrons to cover the opening into the chamber where she'd hidden. More snaps and pops crackled around them, echoing between the high cliffs.
"We need to get out of here," said Grandmother.
They carefully picked their way up out of the debris field to where the path emerged from the avalanche zone, pausing there to again catch their breath.
A slap of running footsteps clapped down from above. Naiva grabbed her spear from her sister and set into a crouch, spear raised, then relaxed as their companions rushed into view. <NAME> ran in the lead, his ghostfire blade blazing with a formidable light.
"Quench that blade!" snapped Grandmother. "It's a flag that will bring every dragon down upon us."
Obedient to his elder's command, the young man drew the magic back inside himself, and the blade dissolved like mist beneath the summer sun. Then he looked at Baishya, who was wearing Naiva's mantle and necklace. He nodded politely at her and hastened over to Naiva.
"Are you all right, Naiva?" he asked with an intent gaze that made her flush warmly. "You must have faced the dragon alone!"
"Not alone, because I always have my twin. But how did you know it was me? We switched mantles."
"Yes, so I see. I suppose you had some hunter's reason for it." His smile wrinkled the skin at the edges of his eyes, like a glimpse into the elder he might one day become if Ojutai or his broodlings did not hunt him down and kill him for the crime of being a ghostfire warrior. "It's true when we first met I thought you two looked exactly alike. But now we've walked together for a few days. I wouldn't mistake you for your sister ever again."
"Why is your face so red, Nai? Too much sun?" demanded Baishya with a smirk. She winked at Tae Jin as she would wink at a cousin, and he blushed too, but he did not move away from Naiva.
Grandmother looked from one to the other, no emotion on her face, before turning to her four loyal hunters. Mattak, Oiyan, Rakhan, and Sorya stared over the debris that buried the open space and the hedron's opening, the only visible residue of a titanic battle won with words and trickery instead of might and blades.
"Was it an illusion?" Mattak asked. "I've never seen a dragon so huge, and so magnificent."
"Magnificent indeed," said Grandmother. "I hope the threat of Ugin's trap means we never see him again."
"If only we could have persuaded him to kill the dragonlords before he departed," Naiva muttered.
"The path of might-have-beens leads only to misery," said Grandmother. "A creature like that does not do favors for others, only for himself. Furthermore, as I know too well myself, when you try to shape selfish dreams into reality, it is the consequences you do not expect that hit you hardest. We are left with what we already had. I'll accept that gratefully. Where is Fec?"
The uneven sound of a final set of footfalls was her answer. The orc arrived last of all, holding a fine chisel in one hand and a horn in the other, his swords sheathed in their scabbard across his back.
"Were you going to attack the dragon with the chisel or the horn?" Grandmother asked with a sardonic lift of an eyebrow.
"It was immediately obvious to me that such a dragon could not be defeated by our feeble magic," Fec said. "So I thought surprise might work where weapons would not."
She chuckled.
"Yet the dragon is gone, and you are alive," Fec added.
"I'll tell you the story when we're resting beneath the overhang, out of sight of roaming dragons. Atarka and Ojutai will send broodlings to investigate today's strange events." Grandmother started up the path. "Girls! Come along!"
Side by side they hurried after Grandmother.
Naiva was almost too delirious with joy to think, yet too brimful of energy to remain silent. So, she spoke the first random question that flew into her mind. "What about the liver and hearts from the broodling? Will we retrieve them on our way home?"
"Yes," said Grandmother.
Just as Naiva started to ask what the organs would be used for, Baishya interrupted breathlessly.
"Do you think I could learn to planeswalk? Or is it a magic reserved only for dragons?"
"Not only for dragons, since I met a Planeswalker before you were born. He seemed in most ways as human as you or me, and was especially disrespectful and a bit tedious when he whined and begged," said Grandmother with a cough of displeasure.
#figure(image("008_Chronicle of Bolas: The Unwritten Now/12.jpg", width: 100%), caption: [Sarkhan, Fireblood | Art by: <NAME>], supplement: none, numbering: none)
But it was more than a cough. She was growing out of breath as they climbed the steep path toward the rim of the canyon and had to lean heavily on her spear when she had never needed its aid before. Where once she had seemed ageless, the difficult journey and the confrontation with the powerful Bolas had exhausted her. Maybe she would not die this year, or even in five years, but mortality had its claws in her. The knowledge sunk its weight into Navia's heart like a stone. Yet now she also understood that Yasova Dragonclaw did not fear death for herself, only the obliteration of her people.
"It's time for you two girls to understand your own responsibilities and how much rests on the shoulders of you young ones," Grandmother went on. "The Temur clan must not die, even if it must sleep, like Ugin, hidden until it may waken again. It can only waken if there are memories remaining to guide it."
"How can carvings be enough?" Naiva asked.
"Enough for what? Nothing can remain the same as it was in the days of my youth, or yours, once you are old. Change is master of us all."
They reached the overhang. Mattak and Oiyan went back outside to stand sentry, while Rakhan and Sorya set a pot to boil over a fire. Grandmother sat wearily on a stone, letting her granddaughters fuss about her in a way she would never have done in the past, when she took care of them, raising them from infants to the edge of adulthood. They took off her mantle, tidied her hair, wiped dirt and sweat off her face, and settled her with a hot tisane to warm her hands and strengthen her lungs.
Tae Jin gave Naiva a look. "What can I do?" he asked softly.
Grandmother gestured, indicating the young man should sit beside her. Fec settled across the fire from them and set out a neat row of carving implements on a rock bench. He began working on the horn he'd been carrying, one that would be added to the scrimshaw collection hidden in the caves.
"Tae Jin, you are welcome to stay with us, if that is what you wish," said Grandmother.
"I must return to my master. He has more to teach me. Afterward, it will be my responsibility to pass on my knowledge to those who come after me, so the Jeskai Way does not die." He looked at Naiva, sighed, and gave a slight shake of his head. "This is my duty, no matter what else I might wish for."
"Yes, of course it is," said Grandmother briskly as Naiva wrung her hands but said nothing. In the harsh world of the clans, duty always came first. "Ugin sent you here with a story to tell us with the hope we could use it to drive Bolas away from Tarkir forever. But that isn't the only reason Ugin sent you. The Spirit Dragon understood the lessons taught him by the old wise woman <NAME>. This isn't just about Ugin, and Bolas. This is about the Temur, and the Jeskai, about all the clans on Tarkir. I remember them all, while you young ones never knew that world. Our dragonlords mean to obliterate the knowledge of all that came before. This is why we must do everything we can to safeguard the heart of our ancestors."
She extended an arm. Fec placed the horn in it. Turning the horn, she displayed a beautiful carving, just begun, of two girls standing on a steep mountainside.
"Someday, perhaps long ahead in the unwritten now, people will be born who will find this story, and it will transform their understanding of the world."
She returned the horn to Fec. He set back to work with easy concentration and consummate skill.
Baishya nudged Naiva and whispered, "I told you Grandmother took him into the tribe for a reason."
"I must return to Ayagor and hunt for Atarka. Above all else, she must believe she has killed all the whisperers. She must never suspect the existence of the Whisper Mind. We do what we must to survive. For now, you girls will stay here."
"But the opening to the hedrons is blocked," Naiva objected.
"With care, it can be dug free. Baishya, you must see if Ugin will continue to communicate with you through the ocean of memories. Fec will record whatever you see. All that he carves will be stored here with the rest of our hidden stories. Naiva will hunt for you, and keep you safe."
#figure(image("008_Chronicle of Bolas: The Unwritten Now/13.jpg", width: 100%), caption: [Highland Game | Art by: <NAME>sell], supplement: none, numbering: none)
"Will we ever be safe?" Naiva asked.
"Safe merely means the last dragon we've seen is flying away from us. As for Bolas, I hope he will consider it too risky to return to Tarkir."
"You lied to him," Naiva added. "What if his story is the true one, and Ugin's story the lie meant to manipulate us into saving his essence from Bolas's revenge?"
"We will never know." She bent her gaze on Tae Jin, who was sitting as still and silent as the waters of the Meditation Realm the twins had wandered. "I know you must return to your master. But let me ask you to please remain here for some months at least. I would like you to recite Ugin's story once again to Fec so it can be carved and preserved in more than one place. We people of the clans must work together to save ourselves. That is the only way. That is also Ugin's message to us."
Naiva held her breath as Tae Jin met Grandmother's stern gaze. But he smiled and, with a swift, shy glance at her, nodded. "Yes. I will stay here for a while."
A blaze of elation jolted her. She didn't mean to smile, yet she couldn't stop the big grin that creased her face.
Baishya snorted and kicked Naiva in the shins.
"Ouch!" But Naiva laughed.
Tae Jin blushed again, gave a stiff cough behind a hand, and said with lofty solemnity, "I'm still injured. I can't hope to outrun or outclimb Ojutai's broodlings until I have recovered my full strength."
"Yes, of course that's why," said Baishya with an extravagant eye roll.
Naiva pinched her, and Baishya elbowed her hard.
Grandmother smiled one of her rare, relaxed smiles. "This is your task, my girls. Children will be born knowing no other way than that of dragonlords. They will think it has always been this way, that humans can only bow to dragons, that the great dragons can't be defeated. But Ugin's story taught us another lesson, one the Spirit Dragon may not have intended. Even the greatest of dragons can die."
"Do you truly think so?" Naiva asked.
"I truly do. For in the unwritten now, anything may come to pass."

実際、main関数のみ定義し、そこにすべてを定義したmain.rsファイルのみで本番稼働させているシステムは限りなく0に近い。
main関数は数行書き、最小限の責務を担う関数を複数定義してそれらを組み合わせて成り立たせるのが一般的だろう。
変数名$x$や$y$ではなく、わかりやすい英語を使うだろう。
もちろん、main関数にすべて書いた巨大なmain関数でも、変数名$a,b,c$だらけでも同じ挙動はするのだが、様々な問題がある。
- 作者（コーダー）が離職・入院・異動したとき
- 障害が発生したとき
- リファクタリングを実施するとき
上記のような"保守開発"フェーズでは、なにより保守性がキーとなる。
誰が読んでも、同じような改修の仕方になるような、そしてすぐ理解できるようなものがいいのである。
保守性が高いシステムは何か起きてもエラーの種類によってはすぐ改修することができるだろう。
これは運用サービスの品質に直結する。
品質のために保守性を担保するのは当然のことなのだが、それ以前にSEとしてのマナーでもあってほしい。
誰かが保守に困るようなものを世にリリースするべきではない。
また、業種にもよるが、感覚的に殆どのSEという職種はプロジェクト単位で参画したり退却したりする。
転職が珍しくない環境下で、同じ担当者が何年も同じ会社にいると思わない方が良い。
さて、設計論は１つのベストプラクティスがあるわけではなく、複数存在する。
ここではその中の１つのみ案内する。
== クリーンアーキテクチャへの招待
ドメインモデル、ユースケース、プレゼンテーションに分かれる。
これらは輪となり、変更が少ない情報ほど内に配置される。
ドメインモデルは設計の核であり、そのシステムを開発することになった発端でもある。
この核はシステム開発となんら関係ない普遍的なものになり、一般にビジネスロジックという。
例えば、「じゃんけんではグーがチョキに勝つ」等の情報レベルで、ここに変更を入れることはできない。
システム仕様ではなく、原則や規則にあたる。
ユースケースは、ドメインモデルを取扱い、ユーザ（クライアント）からの指令を果たす。
例えば、チョキとグーという二つの入力を受け取り、どちらが勝者なのか判定を返却する。
ただし、ユースケース自身は「チョキよりグーの方が強い」ことに関心は無く、あくまでドメインモデルに問合せているに過ぎない。
また、問合せ結果を返却する責務に留まり、クライアントに対して直接「勝ちました/負けました」を表示するのは、プレゼンテーションが担当する。
プレゼンテーションは常にクライアントと対峙している。
フォントサイズ、色、位置、テキスト入力など、システムとユーザが接する窓口（インターフェース）である。
飲食店の場合、ホールがプレゼンテーション、料理をマニュアル通りに調理するキッチンがユースケース、料理そのものがドメインモデルに相当する。
実際の開発プロセスでは、より複雑な概念や抽象的な事象を捉えていく必要があるため、ここではざっくりとした説明に留めた。
エンティティと値オブジェクト、ドメイン貧血、インフラストラクチャー層や依存性逆転の法則にまだ触れていないため、じゃんけんや飲食店の例は当たらずといえども遠からずである.
それぞれの責務ごとに明確にレイヤーを隔離することにより、テスタビリティや保守性を担保する。

#emph[Ah, the smell of bubbling tar! The warm kiss of volcanic ruptures! After all this time spent toiling in the frozen corners of this accursed plane, it reminds me of home. If only every branch along that damnable World Tree could be more like Immersturm! If you ask me, all of Kaldheim would be improved with a touch more fire, a dash of anarchy. Which, if I've done my job right, is exactly where it's all heading.]
#emph[Yes, there's no doubt in my mind that all this plotting, these months of hard work, will come together nicely. But I must admit, there is one thought which keeps me up at night: what if, as the world burns around them, nobody knows who lit the match?]
#emph[This plane is lousy with storytellers. Listen long enough and all their tales blend together: they love to repeat the same drivel about good and evil, heroes and villains, right and wrong. Let's give them something fresh. A story to remember—the last saga of Kaldheim. And I promise, it's got an ending to die for. . .]
The saga begins with a planeswalker named Tibalt. Not only was he powerful and brilliant, but he was also despised by most everyone he met on account of his many gifts—not that it bothered him. However, on account of his many jealous enemies, Tibalt traveled often from place to place and never stayed on one plane for too long. This is the story of how he came to Kaldheim, and how he met the Horrible Beast.
See, this Horrible Beast had heard about Tibalt's many talents and desperately needed his help. The beast knew that a handsome and powerful planeswalker such as Tibalt would never stoop to helping a hideous, stupid monster unless his hand was forced, so the Horrible Beast snuck up on him one day and stuck Tibalt with a nasty, tricky sort of poison. He called this poison a "seed"—and the only way the Horrible Beast would remove it was if Tibalt caused a distraction on his behalf.
What the monster didn't realize was that Tibalt had already been planning to stir up trouble in Kaldheim. So, while the wise and mighty planeswalker agreed to the Horrible Beast's terms, he was really only doing what he had meant to do anyway.

#v(0.35em)
First, Tibalt needed a disguise. Nobody would listen to some newcomer, after all. With Tibalt's vast reservoir of cunning, it was easy enough to find Valki. It happened that this God of Lies, this Prince of Tricksters, was foolish enough to get lied to and tricked himself. How about that?
Tibalt wrapped Valki in magical chains and brought him to the coldest, most remote realm he could find: Karfell. There was this frozen mummy of a king there who Tibalt had worked out a deal with. So long as Valki stayed deep in the dungeon of this King Narfi's glacial palace, Narfi and his Dread Marn—that's what this king called the walking stiffs making up his army—could have the first pick of treasure when the Doomskar started. And oh, what a Doomskar it would be!
Never had Tibalt seen a greedier, more gold-crazed bunch of zombies! The denizens of the other realms, he knew, would need a bit more convincing before they were willing to march to war.
#figure(image("005_Episode 3: The Saga of Tibalt/01.jpg", width: 100%), caption: [Valki, God of Lies | Art by: <NAME>], supplement: none, numbering: none)
The next step in Tibalt's masterful plan was to suit up in his new disguise as Valki and visit Koll the Forgemaster. Koll was one of the dwarves—that metal-brained, oblivious species of blacksmiths—and it just so happened that Koll was the greatest of them all, for whatever that was worth. He was the only one who could work with Tyrite, the hardened sap of the World Tree, which had all sorts of interesting properties. Koll was making a sword out of the stuff, a blade which could open paths between all the realms of Kaldheim. It was supposed to be for Halvar, the god of battle—every plane has one of those dumb brutes, you know—but the thing was, Tibalt needed it. Crossing between the realms was a real pain otherwise, and he had a lot of work to do up and down the World Tree. Koll was awfully stubborn about handing it over to Valki—something about Halvar saving him from a giant wolf and Valki being the God of Lies—so Tibalt did the realms a favor and pushed the obnoxious dwarf right into his own forge.
#figure(image("005_Episode 3: The Saga of Tibalt/02.jpg", width: 100%), caption: [The Trickster-God's Heist | Art by: <NAME>], supplement: none, numbering: none)
Tibalt took his act to Skemfar, home of the elves, and sought an audience with their king. King Harald, son of Hraldir, the very same elf who had united the warring clans of Wood and Shadow, was known across the realms as a wise and steadfast leader. He was known to #emph[Tibalt] , though, as a proud, paranoid fool who believed the elves should be in charge of every last twig in Kaldheim, and hatred and mistrust of the Skoti—the gods of Kaldheim—had long ago settled into the bones of every elf in Skemfar.
Oh, if you could have seen the royal court that day! The lies that clever Tibalt wove—the dark cloud that settled over Harald as he heard of all the terrible things the gods had planned for his people, too terrible even for the mischievous Valki to stand idly by! The only choice, if the elves were to survive, was clear: strike first.
#figure(image("005_Episode 3: The Saga of Tibalt/03.jpg", width: 100%), caption: [Harald, King of Skemfar | Art by: <NAME>], supplement: none, numbering: none)
In Surtland, Tibalt warned the frost giants of an incursion of Torga trolls, awakened from their long slumber. In Bretagard, he promised the vicious Skelle clan the return of their demon master, Varragoth. All across the realms of Kaldheim, Tibalt sowed the seeds of war and chaos.
But what of Starnheim? The Valkyries—well, they presented a problem, even to cunning Tibalt. They were duty-bound creatures, separate from the politics that controlled the other realms. They cared not for gold or power, and they feared no other mortal force in Kaldheim. What could a dedicated trickster do with such rigid, inflexible souls?
We pause the saga, for a moment, to recount a saying common throughout the multiverse: the branch that doesn't bend, breaks.
Tibalt may have been both brilliant and powerful, but he wasn't strong enough to take on every shepherd and reaper in the halls of Starnheim. There was a being, though, that could! Koma, he was called—the Cosmos Serpent, first and oldest of the monsters birthed from the World Tree. Long ago, the Skoti had banished Koma from entering the realms, trapping him in the empty Cosmos. For eons, his restlessness grew, his hunger went unsated and his thirst for destruction unquenched. Tibalt pitied the poor snake; he really did. So, with the Sword of the Realms, he cut open a doorway to the home of the Valkyries, where the Cosmos Serpent could make up for lost time.
#figure(image("005_Episode 3: The Saga of Tibalt/04.jpg", width: 100%), caption: [Open the Omenpaths | Art by: <NAME>s], supplement: none, numbering: none)
Now, Tibalt was no great believer in swords. His faith laid with knives, with hooks, with hellfire and brimstone—but even Tibalt had to admit that the Sword of the Realms had proven very useful. He had crossed the Cosmos with it, time and again. He had used it to unleash Koma on the Valkyries of Starnheim. Now, he was using it for a far more humble task, though one just as important—he was leaving a trail, dragging the tip through the black basalt surface of Immersturm. It was important, after all, that the planeswalker follow him here.
The end of the saga isn't written yet, but let me jump ahead and tell you how it ends: Tibalt kills the planeswalker. The last thing she sees, as the life drains from her eyes, is Kaldheim burning. #emph[All ] the realms, together at last in one great and glorious conflagration.

此開卷第一回也。作者自云曾歷過一番夢幻之後，故將真事隱去，而借「通靈」說此《石頭記》一書也，故曰「甄士隱」云云。但書中所記何事何人？自己又云：今風塵碌碌，一事無成，忽念及當日所有之女子，一一細考較去，覺其行止見識皆出我之上，我堂堂鬚眉，誠不若彼裙釵。我實愧則有餘，悔又無益，大無可如何之日也！當此日，欲將已往所賴天恩祖德錦衣紈袴之時，飫甘饜肥之日，背父兄教育之恩，負師友規訓之德，以致今日一技無成，半生潦倒之罪，編述一集，以告天下。知我之負罪固多，然閨閣中歷歷有人，萬不可因我之不肖自護己短，一并使其泯滅也。所以蓬牖茅椽，繩床瓦灶，並不足妨我襟懷。況那晨風夕月，階柳庭花，更覺得潤人筆墨。我雖不學無文，又何妨用假語村言敷衍出來，亦可使閨閣昭傳，復可破一時之悶，醒同人之目，不亦宜乎？故曰「賈雨村」云云。更於篇中間用「夢」「幻」等字，卻是此書本旨，兼寓提醒閱者之意。

勢鎮汪洋，威寧瑤海。勢鎮汪洋，潮湧銀山魚入穴；威寧瑤海，波翻雪浪蜃離淵。水火方隅高積上，東海之處聳崇巔。丹崖怪石，削壁奇峰。丹崖上，彩鳳雙鳴；削壁前，麒麟獨臥。峰頭時聽錦雞鳴，石窟每觀龍出入。林中有壽鹿仙狐，樹上有靈禽玄鶴。瑤草奇花不謝，青松翠柏長春。仙桃常結果，修竹每留雲。一條澗壑籐蘿密，四面原堤草色新。正是百川會處擎天柱，萬劫無移大地根。

## What?
`tinytable` is a small but powerful `R` package to draw beautiful tables
in a variety of formats: HTML, LaTeX, Word, PDF, PNG, Markdown, and
Typst. The user interface is minimalist and easy to learn, while giving
users access to powerful frameworks to create endlessly customizable
tables.
<https://vincentarelbundock.github.io/tinytable/>
## Why?
There are already many excellent table-drawing packages in the `R`
ecosystem. Why release a new one? As [the maintainer of
`modelsummary`](https://modelsummary.com), I needed a table-drawing
package which was:
- *Simple*: Streamlined, consistent, and uncluttered user interface,
with few functions to learn.
- *Flexible*: Expressive frameworks to customize tables in HTML and
LaTeX formats.[1]
- *Zero-dependency*: Avoid importing any other `R` package.[2]
- *Concise*: Draw beautiful tables without typing a lot of code.
- *Safe*: User inputs are checked thoroughly, and informative errors
are returned early.
- *Maintainable*: A small code base which does not rely on too many
complex regular expressions.
- *Readable*: HTML and LaTeX code should be human-readable and
editable.
- *Free*: This package will always be free. Tiny tables for a tiny
price!
To achieve these goals, the design philosophy of `tinytable` rests on
three pillars:
1. *Data is separate from style.* The code that this package creates
keeps the content of a table separate from the style sheet that
applies to its cells. This is in contrast to other `R` packages that
modify the actual text in each cell to style it. Keeping data and
style separate allows `tinytable` to create human-readable files
which are easy to edit, debug, and extend. It also enables
developers to keep a simpler code base, with minimal use of messy
regular expressions.
2. *Flexibility.* Users’ needs are extremely varied, and a
table-drawing package must be flexible enough to accomodate
different ideas. To achieve this, `tinytable` builds on
battle-tested and versatile frameworks like `Bootstrap` for HTML and
`tabularray` for LaTeX.
3. [*Lightweight is the right weight.*](https://www.tinyverse.org/)
Some of the most popular table-drawing packages in the `R` ecosystem
are very heavy: A single `library()` call can sometimes load upwards
of 65 `R` packages. In contrast, `tinytable` imports zero 3rd party
`R` package by default.
## Installation
`tinytable` is a relatively new package with rapid development. If you
want to benefit from the latest features—showcased on the package
website—you should install from R-Universe:
``` r
install.packages("tinytable", repos = "https://vincentarelbundock.r-universe.dev")
```
Alternatively, you can install it from CRAN:
``` r
install.packages("tinytable")
```
Restart `R` completely for the installation to take effect.
## First steps
The best feature of `tinytable` is its simplicity. To draw a table,
simply call the `tt()` function with your data frame as the first
argument:
``` r
library(tinytable)
x <- mtcars[1:5, 1:5]
tt(x)
```
<p align="center">
<img src="man/figures/readme_01.png" height = "180" class = "center">
<br>
More complex tables can be created by calling arguments and chaining
functions together. In the next example, we add a caption, footnote,
colors, styles, and spanning column headers:
``` r
cap <- "A simple \\texttt{tinytable} example."
not <- "Nullam odio est, ullamcorper scelerisque lectus a, eleifend luctus nisl. Etiam ullamcorper, nibh vel interdum auctor, odio nulla mollis tortor, vel fringilla ante quam quis est."
tt(x,
caption = cap,
notes = not,
width = .5) |>
style_tt(
i = 1:3,
j = 1:2,
background = "teal",
color = "white",
bold = TRUE) |>
group_tt(
j = list("Halloumi" = 1:2, "Tofu" = 4:5))
```
<p align="center">
<img src="man/figures/readme_02.png" height = "350" class = "center">
<br>
## Tutorial
The `tinytable` 0.5.0 tutorial will take you much further. It is
available in two formats:
- [Tutorial
(PDF)](https://vincentarelbundock.github.io/tinytable/vignettes/tinytable_tutorial.pdf)
- Tutorial (HTML):
- [Tiny

- [Format](https://vincentarelbundock.github.io/tinytable/vignettes/format.html)
- [Style](https://vincentarelbundock.github.io/tinytable/vignettes/style.html)
- [Group

- [Plots and
images](https://vincentarelbundock.github.io/tinytable/vignettes/plot.html)
- [Themes](https://vincentarelbundock.github.io/tinytable/vignettes/theme.html)
- [Customization](https://vincentarelbundock.github.io/tinytable/vignettes/custom.html)
- [FAQ](https://vincentarelbundock.github.io/tinytable/vignettes/faq.html)
- [Alternatives](https://vincentarelbundock.github.io/tinytable/vignettes/alternatives.html)
[1] Other formats like Markdown and Typst are also available, but less
flexible.
[2] Some extra packages can be imported to access specific
functionality, such as integration with Quarto, inserting `ggplot2`
objects as inline plots, and saving tables to PNG images or PDF
documents.

== Hidden Bibliographies
#outline()
In some documents, such as a letter, you may want to cite a reference without printing a bibliography.
This can easily be achieved by wrapping your `bibliography(...)` with the `hidden-bibliography` function after importing the `hidden-bib` package. @hidden-bib
The code then looks like this:
```typ
#import "@preview/hidden-bib:0.1.0": hidden-bibliography
#lorem(20) @example1
#lorem(40) @example2[p. 2]
#hidden-bibliography(
bibliography("/refs.yml")
)
```
#lorem(20) @example1
#lorem(40) @example2[p. 2]
*Note that this automatically sets the `style` option to `"chicago-notes"` unless you specify a different style.*
#hidden-bibliography(
bibliography("refs.yml")
)
== Another section that appears in the outline

title: "Các phương pháp phục chế màu cho ảnh độ xám",
authors: (
"<NAME> - 20127298",
),
)
= Các phương pháp phổ biến
Có rất nhiều công trình nghiên cứu liên quan đến việc phục chế ảnh độ sáng trong đó hầu hết các phương pháp đều dựa trên các phương pháp chính như là:
- Sử dụng phương pháp color mapping / gradient mapping trên độ xám
- Sử dụng một mô hình máy học
= Khôi phục màu bằng phương pháp color mapping
== Nguyên lý hoạt động
Khi chuyển ảnh độ xám thành ảnh màu, một trong số phương pháp đơn giản nhất đó là sử dụng phương pháp color mapping.
Phương pháp này coi một phân vùng nào đó sẽ thiên theo một dải màu nhất định và sẽ áp các công thức để ước lượng 3 kênh R, G, B theo độ sáng tại điểm ảnh đó.
#figure(
image("images/colormaps.png"),
caption: "So sánh một số dải màu phổ biến."
) <colormaps>
Phương pháp này tốt khi muốn áp dụng cùng với lập trình shader, vì nó chỉ quan tâm đến theo một điểm ảnh mà không cần quan tâm các thông tin khác ở xung quanh.
== Hạn chế
Tuy nhiên ở thực tế toàn bộ bức ảnh không chỉ thiên theo một dải màu nhỏ đó. Nếu áp colormapping cho cả một bức ảnh thường sẽ cho ra kết quả khác xa so với thực tế.
#figure(
image("images/single_colormapping.png"),
caption: "Áp dụng duy nhất một phương pháp colormapping."
) <single_colormapping>
== Các cải tiến về phương pháp
Phương pháp này có thể được cải tiến bằng cách tách một bức ảnh ra nhiều phân vùng, và mỗi phân vùng này lựa dải màu thích hợp để đưa ra kết quả gần với thực nhất.
#figure(
image("images/colormapping_segmentation.png"),
caption: "Chia nhiều phân vùng và colormapping."
) <colormapping_segmentation>
Việc phân vùng có thể được lựa chọn bằng tay hoặc thông qua các mô hình học máy để xác định.

# University Theme
This theme is courtesy of [<NAME>](https://github.com/drupol).
## Initialization
You can initialize it with the following code:
```typst
#import "@preview/touying:0.2.1": *
#let s = themes.university.register(s, aspect-ratio: "16-9")
#let s = (s.methods.info)(
self: s,
title: [Title],
subtitle: [Subtitle],
author: [Authors],
date: datetime.today(),
institution: [Institution],
)
#let (init, slide, slides, title-slide, focus-slide, matrix-slide, touying-outline, alert) = utils.methods(s)
#show: init
```
The `register` function takes the following parameters for initialization:
- `aspect-ratio`: Sets the aspect ratio of the slides to "16-9" or "4-3," with the default being "16-9."
- `progress-bar`: Determines whether to display the progress bar at the top of the slides, with the default value of `true`.
Additionally, the University theme provides an `#alert[..]` function that you can use with `#show strong: alert` using the `*alert text*` syntax.
## Color Themes
University theme defaults to using:
```typst
#let s = (s.methods.colors)(
self: s,
primary: rgb("#04364A"),
secondary: rgb("#176B87"),
tertiary: rgb("#448C95"),
neutral-lightest: rgb("#FBFEF9"),
)
```
You can modify the color theme by using `#let s = (s.methods.colors)(self: s, ..)`.
## Slide Function Family
The University theme provides a series of custom slide functions:
```typst
#title-slide(logo: none, authors: none, ..args)
```
The `title-slide` reads information from `self.info` for display, and you can pass in the `logo` parameter and an array-type `authors` parameter.
---
```typst
#slide(
repeat: auto,
setting: body => body,
composer: utils.side-by-side,
section: none,
subsection: none,
// university theme
title: none,
subtitle: none,
header: none,
footer: auto,
margin: (top: 2em, bottom: 1em, x: 0em),
padding: (x: 2em, y: .5em),
)[
...
]
```
The default ordinary slide function with a title and footer, where `title` defaults to the current section title, and the footer is set by you.
---
```typst
#focus-slide(background-img: ..., background-color: ...)[
...
]
```
Used to capture the audience's attention, with the default background color being `self.colors.primary`.
---
```typst
#matrix-slide(columns: ..., rows: ...)[
...
][
...
]
```
You can refer to the [documentation](https://polylux.dev/book/themes/gallery/university.html).
## `slides` Function
The `slides` function has the parameter:
- `title-slide`: Defaults to `true`.
You can set it using `#show: slides.with(..)`.
```typst
#import "@preview/touying:0.2.1": *
#let s = themes.university.register(s, aspect-ratio: "16-9")
#let s = (s.methods.info)(
self: s,
title: [Title],
subtitle: [Subtitle],
author: [Authors],
date: datetime.today(),
institution: [Institution],
)
#let (init, slide, slides, title-slide, focus-slide, matrix-slide, touying-outline, alert) = utils.methods(s)
#show: init
#show: slides
= Title
== First Slide
Hello, Touying!
#pause
Hello, Typst!
```
## Example
```typst
#import "@preview/touying:0.2.1": *
#let s = themes.university.register(s, aspect-ratio: "16-9")
#let s = (s.methods.info)(
self: s,

)
#let (init, slide, slides, title-slide, focus-slide, matrix-slide, touying-outline, alert) = utils.methods(s)
#show: init
#title-slide(authors: ("Author A", "Author B"))
#slide(title: [Slide title], section: [The section])[

= Concepts
The core concept behind the FBDL is based on the fact that if there is a system part with the registers that can be accessed, then there is at least one more system part accessing these registers.
The part accessing the registers is called the _requester_.
The part containing the registers is called the _provider_, as it provides functions via particular functionalities.
The code generated from the FBDL description can be conceptually divided into two parts, the requester part and the provider part.
The requester code usually refers to the generated software or firmware implemented in typical programming languages such as: Ada, C, C++, Go, Java, Python, Rust etc.
The provider code usually refers to the generated gateware or hardware implemented in hardware description languages or frameworks such as: VHDL, SystemVerilog, SystemC, Bluespec, PipelineC, MyHDL, Chisel etc.
However, implementing the provider, for example as a firmware, using the C language and a microcontroller is practically doable and valid.
The description of functionalities shall be placed in files with the `.fbd` extension.
By default, the bus named `Main` is the entry point for the description used for the code generation.
A compiler is free to support a parameter for changing the name of the main bus.
```
description ::=
import_statement |
constant_definition |
type_definition |
instantiation
```
== Properties <concepts-properties>
Each data in the FBDL description has associated functionality and each functionality has associated properties.
Properties allow the configuration of functionalities.
Each property must have a concrete type.
The default value of each property is specified in the round brackets ( ) in the functionality subsections.
If the default value is `bus width`, then the default value equals the actual value of the bus `width` property.
If the default value is `uninitialized`, then it shall be represented as the uninitialized meta value at the provider side.
If the target language for the provider code does not have a concept of uninitialized value, then values such as 0, `Null`, `None`, `nil` etc. shall be used.
Each property either defines or declares functionality feature or behavior.
Definitive properties specify the desired behavior of the automatically generated code.
They specify elements directly managed by the FBDL.
Examples of definitive properties include `atomic` or `width` properties.
Declarative properties describe the behavior of external elements that automatically generated code only interacts with.
Declarative properties are required to generate valid logic, and it is the user's responsibility to make sure their values match the behavior of external components.
Examples of declarative properties include `access` or `in-trigger` properties.
`property_assignment ::= property_identifier `*`=`*` expression`
`property_assignments ::=` \
` property_assignments` \
` { `*`;`*` property_assignment }` \
` newline`
`semicolon_and_property_assignments ::= `*`;`*` property_assignments`
#block(breakable: false)[
`property_identifier ::=` \
#h(1em)
*`access`*` | `
*`add-enable`*` | `
*`atomic`*` | `
*`byte-write-enable`*` | `
*`clear`*` | `
*`delay`*` | `
#linebreak()
#h(1em)
*`enable-init-value`*` | `

#h(1em)
*`read-value`*` | `
*`reset`*` | `
*`reset-value`*` | `
*`size`*` | `
*`width`*
]
== Instantiation
A functionality can be instantiated in a single line or in multiple lines.
`instantiation ::= single_line_instantiation | multi_line_instantiation`
```
single_line_instantiation ::=
identifier
[ array_marker ]
declared_identifier | qualified_identifier
[ argument_list ]
newline | semicolon_and_property_assignments
```
```
multi_line_instantiation ::=
identifier
[ array_marker ]
declared_identifier | qualified_identifier
[ argument_list ]
functionality_body
```
`array_marker ::= `*`[`*` expression ` *`]`*
```
functionality_body ::=
newline
indent
{ constant_definition | type_definition | property_assignments | instantiation }
dedent
```
The following code shows examples of single line instantiations:
#block(breakable:false)[
#pad(left: 1em)[
```fbd
C config
C config; width = 8
M [8]mask; atomic = false; width = 128; init-value = 0
err error_t(48); atomic = false
```
]
]
The following code shows examples of multi line instantiations:
#block(breakable:false)[
#pad(left: 1em)[
```fbd
My_Config config
width = 96
atomic = false
My_Irq irq
add-enable = true
in-trigger = "Edge"
```
]
]
== Addressing
The FBDL specification does not impose any addressing mode, for example, byte or word.
There is also no property allowing to switch between different addressing modes.
The handling of the addressing mode is left to the particular compiler implementation.
Depending on the use case and target bus, at least a few approaches are possible.
+ Suppose the compiler has a monolithic structure (no distinction between the compiler front-end and back-end).
In that case, it is best to use the addressing mode required or preferred by the target bus (for example, byte addressing for AXI or word addressing for Wishbone).
+ Suppose the compiler is just a generic front-end:
- The compiler might provide command line flag or parameter to specify the addressing mode during the compiler call.
- The compiler might assume byte addressing.
The drawback of this approach is that the data bus width must be a multiple of the number of bits in a byte.
In such a case, word addressing is obtained by simply discarding a proper number of the least significant bits of the address bus.
The address bus shift operation is carried out by the compiler back-end.
- The compiler might assume word addressing.
The advantage of this approach is that there is no extra restriction on the data bus width when the back-end utilizes word addressing.
If the back-end utilizes byte addressing, the address is obtained by adding a proper number of the least significant bits to the address bus.
The address bus shift operation is carried out by the compiler back-end.
The back-end must also ensure that the data bus width has the proper value.
== Positive logic
The FBDL uses only positive logic.
An active level in positive logic is a high level (binary 1), and an active edge is a rising edge (transition from the low level to the high level, from binary 0 to binary 1).
It does not mean that FBDL cannot be used with external components using negative logic.
To connect external negative logic components to the generated FBDL positive logic components, one shall negate the signals at the interface connection level.
Supporting both positive and negative logic would unnecessarily complex the language and would create a second way for solving the same problem making the set of possible solutions non-orthogonal.
== Domain-specific language
The FBDL is a domain-specific language with its own syntax.
Some of the register-centric tools are built on top of standard file formats or markup languages such as JSON, TOML, XML or YAML.
Such an approach allows for fast prototyping and has a lower entry threshold.
However, it becomes a burden when more conceptually advanced features, for example parametrization, have to be supported.
The description quickly begins to gain in volume, and the overall feeling is it is needlessly verbose.
What is more, having its own adjusted language syntax allows for more informative compiler error messages.

title: 0.12.0
description: Changes in Typst 0.12.0
---
# Version 0.12.0 (October 18, 2024)
## Highlights
- Added support for multi-column floating [placement]($place.scope) and
[figures]($figure.scope)
- Added support for automatic [line numbering]($par.line) (often used in
academic papers)
- Typst's layout engine is now multithreaded. Typical speedups are 2-3x for
larger documents. The multithreading operates on page break boundaries, so
explicit page breaks are necessary for it to kick in.
- Paragraph justification was optimized with a new two-pass algorithm. Speedups
are larger for shorter paragraphs and go up to 6x.
- Highly reduced PDF file sizes due to better font subsetting (thanks to
[@LaurenzV](https://github.com/LaurenzV))
- Emoji are now exported properly in PDF
- Added initial support for PDF/A. For now, only the PDF/A-2b profile is
supported, but more is planned for the future.
- Added various options for configuring the CLI's environment (fonts, package
paths, etc.)
- Text show rules now match across multiple text elements
- Block-level equations can now optionally break over multiple pages
- Fixed a bug where some fonts would not print correctly on professional
printers
- Fixed a long-standing bug which could cause headings to be orphaned at the
bottom of the page
## Layout
- Added support for multi-column floating placement and figures via
[`place.scope`] and [`figure.scope`]. Two-column documents should now prefer
`{set page(columns: 2)}` over `{show: column.with(2)}` (see the
[page setup guide]($guides/page-setup-guide/#columns)).
- Added support for automatic [line numbering]($par.line) (often used in
academic papers)
- Added [`par.spacing`] property for configuring paragraph spacing. This should
now be used instead of `{show par: set block(spacing: ..)}`
**(Breaking change)**
- Block-level elements like lists, grids, and stacks now show themselves as
blocks and are thus affected by all block properties (e.g. `stroke`) rather
than just `spacing` **(Breaking change)**
- Added [`block.sticky`] property which prevents a page break after a block
- Added [`place.flush`] function which forces all floating figures to be placed
before any further content
- Added [`skew`] function
- Added `{auto}` option for [`page.header`] and [`page.footer`] which results in
an automatic header/footer based on the numbering (which was previously
inaccessible after a change)
- Added `gap` and `justify` parameters to [`repeat`] function
- Added `width` and `height` parameters to the [`measure`] function to define
the space in which the content should be measured. Especially useful in
combination with [`layout`].
- The height of a `block`, `image`, `rect`, `square`, `ellipse`, or `circle` can
now be specified in [fractional units]($fraction)
- The [`scale`] function now supports absolute lengths for `x`, `y`, `factor`.
This way an element of unknown size can be scaled to a fixed size.
- The values of `block.above` and `block.below` can now be retrieved in context
expressions.
- Increased accuracy of conversions between absolute units (pt, mm, cm, in)
- Fixed a bug which could cause headings to be orphaned at the bottom of the
page
- Fixed footnotes within breakable blocks appearing on the page where the
breakable block ends instead of at the page where the footnote marker is
- Fixed numbering of nested footnotes and footnotes in floats
- Fixed empty pages appearing when a [context] expression wraps whole pages
- Fixed `{set block(spacing: x)}` behaving differently from
`{set block(above: x, below: x)}`
- Fixed behavior of [`rotate`] and [`scale`] with `{reflow: true}`
- Fixed interaction of `{align(horizon)}` and `{v(1fr)}`
- Fixed various bugs where floating placement would yield overlapping results
- Fixed a bug where widow/orphan prevention would unnecessarily move text into
the next column
- Fixed [weak spacing]($h.weak) not being trimmed at the start and end of lines
in a paragraph (only at the start and end of paragraphs)
- Fixed interaction of weak page break and [`pagebreak.to`]
- Fixed compilation output of a single weak page break
- Fixed crash when [padding]($pad) by `{100%}`
## Text
- Tuned hyphenation: It is less eager by default and hyphenations close to the
edges of words are now discouraged more strongly
**(May lead to larger layout reflows)**
- New default font: Libertinus Serif. This is the maintained successor to the
old default font Linux Libertine. **(May lead to smaller reflows)**
- Setting the font to an unavailable family will now result in a warning
- Implemented a new smart quote algorithm, fixing various bugs where smart
quotes weren't all that smart
- Added [`text.costs`] parameter for tweaking various parameters that affect the
choices of the layout engine during text layout
- Added `typm` highlighting mode for math in [raw blocks]($raw.lang)
- Added basic i18n for Galician, Catalan, Latin, Icelandic, Hebrew
- Implemented hyphenation duplication for Czech, Croatian, Lower Sorbian,
Polish, Portuguese, Slovak, and Spanish.
- The [`smallcaps`] function is now an element function and can thereby be used
in show(-set) rules.
- The [`raw.theme`] parameter can now be set to `{none}` to disable highlighting
even in the presence of a language tag, and to `{auto}` to reset to the
default
- Multiple [stylistic sets]($text.stylistic-set) can now be enabled at once
- Fixed the Chinese translation for "Equation"
- Fixed that hyphenation could occur outside of words
- Fixed incorrect layout of bidirectional text in edge cases
- Fixed layout of paragraphs with explicit trailing whitespace
- Fixed bugs related to empty paragraphs created via `#""`
- Fixed accidental trailing spaces for line breaks immediately preceding an
inline equation
- Fixed [`text.historical-ligatures`] not working correctly
- Fixed accidental repetition of Thai characters around line breaks in some
circumstances
- Fixed [smart quotes]($smartquote) for Swiss French
- New font metadata exceptions for Archivo, Kaiti SC, and Kaiti TC
- Updated bundled New Computer Modern fonts to version 6.0
## Math
- Block-level equations can now break over multiple pages if enabled via
`{show math.equation: set block(breakable: true)}`.
- Matrix and vector sizing is now more consistent across different cell contents
- Added [`stretch`]($math.stretch) function for manually or automatically
stretching characters like arrows or parentheses horizontally or vertically
- Improved layout of attachments on parenthesized as well as under- or overlined
expressions
- Improved layout of nested attachments resulting from code like
`[#let a0 = $a_0$; $a0^1$]`
- Improved layout of primes close to superscripts
- Improved layout of fractions
- Typst now makes use of math-specific height-dependent kerning information in
some fonts for better attachment layout
- The `floor` and `ceil` functions in math are now callable symbols, such that
`[$ floor(x) = lr(floor.l x floor.r) $]`
- The [`mat.delim`]($math.mat.delim), [`vec.delim`]($math.vec.delim), and
[`cases.delim`]($math.cases.delim) parameters now allow any character that is
considered a delimiter or "fence" (e.g. |) by Unicode. The `{delim: "||"}`
notation is _not_ supported anymore and should be replaced by
`{delim: bar.double}` **(Minor breaking change)**
- Added [`vec.align`]($math.vec.align) and [`mat.align`]($math.mat.align)
parameters
- Added [`underparen`]($math.underparen), [`overparen`]($math.overparen),
[`undershell`]($math.undershell), and [`overshell`]($math.overshell)
- Added `~` shorthand for `tilde.op` in math mode **(Minor breaking change)**
- Fixed baseline alignment of equation numbers
- Fixed positioning of corner brackets (⌜, ⌝, ⌞, ⌟)
- Fixed baseline of large roots
- Fixed multiple minor layout bugs with attachments
- Fixed that alignment points could affect line height in math
- Fixed that spaces could show up between text and invisible elements like
[`metadata`] in math
- Fixed a crash with recursive show rules in math
- Fixed [`lr.size`]($math.lr.size) not affecting characters enclosed in
[`mid`]($math.mid) in some cases
- Fixed resolving of em units in sub- and superscripts
- Fixed bounding box of inline equations when a [text edge]($text.top-edge) is
set to `{"bounds"}`
## Introspection
- Implemented a new system by which Typst tracks where elements end up on the
pages. This may lead to subtly different behavior in introspections.
**(Breaking change)**
- Fixed various bugs with wrong counter behavior in complex layout situations,
through a new, more principled implementation
- Counter updates can now be before the first, in between, and after the last
page when isolated by weak page breaks. This allows, for instance, updating a
counter before the first page header and background.
- Fixed logical ordering of introspections within footnotes and figures
- Fixed incorrect [`here().position()`]($here) when [`place`] was used in a
context expression
- Fixed resolved positions of elements (in particular, headings) whose show rule
emits an invisible element (like a state update) before a page break
- Fixed behavior of stepping a counter at a deeper level than its current state
has
- Fixed citation formatting not working in table headers and a few other places
- Displaying the footnote counter will now respect the footnote numbering style
## Model
- Document set rules do not need to be at the very start of the document
anymore. The only restriction is that they must not occur inside of layout
containers.
- The `spacing` property of [lists]($list.spacing),
[enumerations]($enum.spacing), and [term lists]($terms.spacing) is now also
respected for tight lists
- Tight lists now only attach (with tighter spacing) to preceding paragraphs,
not arbitrary blocks
- The [`quote`] element is now locatable (can be used in queries)
- The bibliography heading now uses `depth` instead of `level` so that its level
can still be configured via a show-set rule
- Added support for more [numbering] formats: Devanagari, Eastern Arabic,
Bengali, and circled numbers
- Added [`hanging-indent`]($heading.hanging-indent) parameter to heading
function to tweak the appearance of multi-line headings and improved default
appearance of multi-line headings
- Improved handling of bidirectional text in outline entry
- Fixed document set rules being ignored in an otherwise empty document
- Fixed document set rules not being usable in context expressions
- Fixed bad interaction between `{set document}` and `{set page}`
- Fixed `{show figure: set align(..)}`. Since the default figure alignment is
now a show-set rule, it is not revoked by `{show figure: it => it.body}`
anymore. **(Minor breaking change)**
- Fixed numbering of footnote references
- Fixed spacing after bibliography heading
## Bibliography
- The Hayagriva YAML `publisher` field can now accept a dictionary with a
`location` key. The top-level `location` key is now primarily intended for
event and item locations.
- Multiple page ranges with prefixes and suffixes are now allowed
- Added `director` and catch-all editor types to BibLaTeX parsing
- Added support for disambiguation to alphanumeric citation style
- The year 0 will now render as 1BC
- Fixes for sorting of bibliography entries
- Fixed pluralization of page range labels
- Fixed sorting of citations by their number
- Fixed how citation number ranges collapse
- Fixed when the short form of a title is used
- Fixed parsing of unbalanced dollars in BibLaTeX `url` field
- Updated built-in citation styles
## Visualization
- Added `fill-rule` parameter to [`path`]($path.fill-rule) and
[`polygon`]($polygon.fill-rule) functions
- Fixed color mixing and gradients for [Luma colors]($color.luma)
- Fixed conversion from Luma to CMYK colors
- Fixed offset gradient strokes in PNG export
- Fixed unintended cropping of some SVGs
- SVGs with foreign objects now produce a warning as they will likely not render
correctly in Typst
## Syntax
- Added support for nested imports like `{import "file.typ": module.item}`
- Added support for parenthesized imports like `{import "file.typ": (a, b, c)}`.
With those, the import list can break over multiple lines.
- Fixed edge case in parsing of reference syntax
- Fixed edge case in parsing of heading, list, enum, and term markers
immediately followed by comments
- Fixed rare crash in parsing of parenthesized expressions
## Scripting
- Added new fixed-point [`decimal`] number type for highly precise arithmetic on
numbers in base 10, as needed for finance
- Added `std` module for accessing standard library definitions even when a
variable with the same name shadows/overwrites it
- Added [`array.to-dict`], [`array.reduce`], [`array.windows`] methods
- Added `exact` argument to [`array.zip`]
- Added [`arguments.at`] method
- Added [`int.from-bytes`], [`int.to-bytes`], [`float.from-bytes`], and
[`float.to-bytes`]
- Added proper support for negative values of the `digits` parameter of
[`calc.round`] (the behaviour existed before but was subtly broken)
- Conversions from [`int`] to [`float`] will now error instead of saturating if
the float is too large **(Minor breaking change)**
- Added `float.nan` and `float.inf`, removed `calc.nan`
**(Minor breaking change)**
- Certain symbols are now generally callable like functions and not only
specifically in math. Examples are accents or [`floor`]($math.floor) and
[`ceil`]($math.ceil).
- Improved [`repr`] of relative values, sequences, infinities, NaN,
`{type(none)}` and `{type(auto)}`
- Fixed crash on whole packages (rather than just files) cyclically importing
each other
- Fixed return type of [`calc.round`] on integers when a non-zero value is
provided for `digits`
## Styling
- Text show rules now match across multiple text elements
- The string `{"}` in a text show rule now matches smart quotes
- Fixed a long-standing styling bug where the header and footer would
incorrectly inherit styles from a lone element on the page (e.g. a heading)
- Fixed `{set page}` not working directly after a counter/state update
- Page fields configured via an explicit `{page(..)[..]}` call can now be
properly retrieved in context expressions
## Export
- Highly reduced PDF file sizes due to better font subsetting
- Emoji are now exported properly in PDF
- Added initial support for PDF/A. For now, only the standard PDF/A-2b is
supported, but more is planned for the future. Enabled via `--pdf-standard
a-2b` in the CLI and via the UI in File > Export as > PDF in the web app.
- Setting [`page.fill`] to `{none}` will now lead to transparent pages instead
of white ones in PNG and SVG. The new default of `{auto}` means transparent
for PDF and white for PNG and SVG.
- Improved text copy-paste from PDF in complex scenarios
- Exported SVGs now contain the `data-typst-label` attribute on groups resulting
from labelled [boxes]($box) and [blocks]($block)
- Fixed a bug where some fonts would not print correctly on professional
printers
- Fixed a bug where transparency could leak from one PDF object to another
- Fixed a bug with CMYK gradients in PDF
- Fixed various bugs with export of Oklab gradients in PDF
- Fixed crashes related to rendering of non-outline glyphs
- Two small fixes for PDF standard conformance
## Performance
- Typst's layout engine is now multithreaded. Typical speedups are 2-3x for
larger documents. The multithreading operates on page break boundaries, so
explicit page breaks are necessary for it to kick in.
- Paragraph justification was optimized with a new two-pass algorithm. Speedups
are larger for shorter paragraphs and range from 1-6x.
## Command Line Interface
- Added `--pages` option to select specific page ranges to export
- Added `--package-path` and `--package-cache-path` as well as
`TYPST_PACKAGE_PATH` and `TYPST_PACKAGE_CACHE_PATH` environment variables for
configuring where packages are loaded from and cached in, respectively
- Added `--ignore-system-fonts` flag to disable system fonts fully for better
reproducibility
- Added `--make-deps` argument for outputting the dependencies of the current
compilation as a Makefile
- Added `--pretty` option to `typst query`, with the default now being to minify
(only applies to JSON format)
- Added `--backup-path` to `typst update` to configure where the previous
version is backed up
- Added useful links to help output
- The CLI will now greet users who invoke just `typst` for the first time
- The document can now be written to stdout by passing `-` as the output
filename (for PDF or single-page image export)
- Typst will now emit a proper error message instead of failing silently when
the certificate specified by `--cert` or `TYPST_CERT` could not be loaded
- The CLI now respects the `SOURCE_DATE_EPOCH` environment variable for better
reproducibility
- When exporting multiple images, you can now use `{t}` (total pages), `{p}`
(current page), and `{0p}` (zero-padded current page, same as current `{n}`)
in the output path
- The input and output paths now allow non-UTF-8 values
- Times are now formatted more consistently across the CLI
- Fixed a bug related to the `--open` flag
- Fixed path completions for `typst` not working in zsh
## Tooling and Diagnostics
- The "compiler" field for specifying the minimum Typst version required by a
package now supports imprecise bounds like 0.11 instead of 0.11.0
- Added warning when a label is ignored by Typst because no preceding labellable
element exists
- Added hint when trying to apply labels in code mode
- Added hint when trying to call a standard library function that has been
shadowed/overwritten by a local definition
- Added hint when trying to set both the language and the region in the `lang`
parameter
- Added hints when trying to compile non-Typst files (e.g. after having typed
`typst c file.pdf` by accident)
- Added hint when a string is used where a label is expected
- Added hint when a stray end of a block comment (`*/`) is encountered
- Added hints when destructuring arrays with the wrong number of elements
- Improved error message when trying to use a keyword as an identifier in a let
binding
- Improved error messages when accessing nonexistent fields
- Improved error message when a package exists, but not the specified version
- Improved hints for unknown variables
- Improved hint when trying to convert a length with non-zero em component to an
absolute unit
- Fixed a crash that could be triggered by certain hover tooltips
- Fixed an off-by-one error in to-source jumps when first-line-indent is enabled
- Fixed suggestions for `.` after the end of an inline code expressions
- Fixed autocompletions being duplicated in a specific case
## Symbols
- New: `parallelogram`, `original`, `image`, `crossmark`, `rest`, `natural`,
`flat`, `sharp`, `tiny`, `miny`, `copyleft`, `trademark`, `emoji.beet`,
`emoji.fingerprint`, `emoji.harp`, `emoji.shovel`, `emoji.splatter`,
`emoji.tree.leafless`,
- New variants: `club.stroked`, `diamond.stroked`, `heart.stroked`,
`spade.stroked`, `gt.neq`, `lt.neq`, `checkmark.heavy`, `paren.double`,
`brace.double`, `shell.double`, `arrow.turn`, `plus.double`, `plus.triple`,
`infinity.bar`, `infinity.incomplete`, `infinity.tie`, `multimap.double`,
`ballot.check`, `ballot.check.heavy`, `emptyset.bar`, `emptyset.circle`,
`emptyset.arrow.l`, `emptyset.arrow.r`, `parallel.struck`, `parallel.eq`,
`parallel.equiv`, `parallel.slanted`, `parallel.tilde`, `angle.l.curly`,
`angle.l.dot`, `angle.r.curly`, `angle.r.dot`, `angle.oblique`, `angle.s`,
`em.two`, `em.three`
- Renamed: `turtle` to `shell`, `notes` to `note`, `ballot.x` to `ballot.cross`,
`succ.eq` to `succ.curly.eq`, `prec.eq` to `prec.curly.eq`, `servicemark` to
`trademark.service`, `emoji.face.tired` to `emoji.face.distress`
**(Breaking change)**
- Changed codepoint: `prec.eq`, `prec.neq`, `succ.eq`, `succ.neq`, `triangle`
from ▷ to △, `emoji.face.tired` **(Breaking change)**
- Removed: `lt.curly` in favor of `prec`, `gt.curly` in favor of `succ`
**(Breaking change)**
## Deprecations
- [`counter.display`] without an established context
- [`counter.final`] with a location
- [`state.final`] with a location
- [`state.display`]
- [`query`] with a location as the second argument
- [`locate`] with a callback function
- [`measure`] with styles
- [`style`]
## Development
- Added `typst-kit` crate which provides useful APIs for `World` implementors
- Added go-to-definition API in `typst-ide`
- Added package manifest parsing APIs to `typst-syntax`
- As the compiler is now capable of multithreading, `World` implementations must
satisfy `Send` and `Sync`
- Changed signature of `World::main` to allow for the scenario where the main
file could not be loaded
- Removed `Tracer` in favor of `Warned<T>` and `typst::trace` function
- The `xz2` dependency used by the self-updater is now statically linked
- The Dockerfile now has an `ENTRYPOINT` directive

Seule la direction importe, le sens sera apporté par la charge sur laquelle on "appliquera" le champ.
Quand on a une surface avec une forme facile (symmétrique) on peut faire :
$ Phi_E = integral arrow(E(r)) dot d arrow(S) = Q_"int"/epsilon_0 $
En fait on va entourer nos charges avec une forme (par exemple une sphère), donc on aura $Q_"int"$ et on va calculer
$d arrow(S)$ est toujours orthogonal à la surface par laquelle les charges passent (donc si le champ est dans le même sens alors le produit scalaire fera 1).
== Potentiel électrique
Ce n'est pas un vecteur. C'est comparable à la hauteur en méca.
Comment calculer $V$ *en un point* ? Charge(s) ponctuelle(s) :
$ V(r) = sum_i^n k Q_i/r_i $
Pour une surface avec une distribution de charges continue :
$ V(r) = integral_S k d_q/r $
Attention $V$ est un scalaire, pas un vecteur !
$ E - nabla V $
== Conservation de l'énergie
$ E = K + U $
L'énergie cinétique et l'énergie potentielle d'une charge $q$ dans un potentiel électrique $V$ créé par d'autres charges :
$ K = 1/2 m v^2 $
$ U = V dot q $
U s'exprime toujours comme une énergie potentielle entre une charge et une ou plusieurs autres charges.
En méca, l'énergie potentielle dépend du champ dans lequel la charge est introduite (en méca $U = m g h$). En électromag pareil, elle dépend des autres charges présentes autour.
L'énergie potentielle est définie à une constante près. En méca on dit que $U("surface de la Terre") = 0$ pour simplifier les calculs. En électromag on dit $U(infinity) = 0$ (quand les deux charges sont éloignées à l'infini alors l'énergie potentielle est nulle).
$ W_(A arrow B) = Delta U $
(par exemple en méca $W_(A arrow B) = m g h_a - m g h_b$)
Si $nabla V = 0$, le potentiel est constant, ça signifie que le champ est nul dans la direction dans laquelle on effectue le travail, mais on peut avoir un champ perpendiculaire à la direction.
== Propriété des conducteurs dans un cas électrostatique
- $arrow(E) = 0$ à l'intérieur
- à l'intérieur ce n'est pas chargé (il y a un équilibre)
- $arrow(E)$ est $perp$, car c'est à la surface que toutes les charges se trouvent (et toute composante du champ parallèle ferait bouger les charges, ce qui n'est pas autorisé).
== Formule de Poisson
On part de la formule de Gauss:
$ integral_S arrow(E) dot d arrow(S) = Q_"int"/epsilon_0 $
Intégrer sur la surface c'est comme intégrer sur le volume en dérivant le vecteur :
$ arrow.double.r.l integral_V arrow(nabla) dot arrow(E) dot d V = Q_"int"/epsilon_0 $
On retrouve la charge :
$ arrow.double.r.l arrow(nabla) dot arrow(E) integral_V d V = 1/epsilon_0 integral_V rho dot d V $
$ arrow.double.r.l arrow(nabla) dot arrow(E) integral_V d V = rho/epsilon_0 integral_V d V $
*$ arrow.double.r.l arrow(nabla) dot arrow(E) = rho/epsilon_0 $*
$ arrow.double.r.l arrow(nabla)^2dot arrow(V) = rho/epsilon_0 $
== Capacité
Dans le cas d'un condensateur, $Q = C dot V$
Ou $Q = C/(Delta V)$ pour un condensateur, avec $Delta V$ la différence de potentiel entre les deux plaques.
$ C = (epsilon A)/d $
donc C ne dépend que de la géométrie du condensateur
$d$ distance entre les plaques (en mètres) \
$A$ l'aire des plaques (en mètres carrés) \
$epsilon$ permissivité du milieu entre les plaques (la capacité ne dépend donc pas uniquement de la géométrie mais aussi du facteur $chi_i$ du matériau)
$ E = E_0 / K $
$E_0$ le champ électrique si on était dans l'air \
$K$ la constante diélectrique du milieu
Calculer une différence de potentiel avec différents milieux:
$ V(A) - V(B) = integral_0^("fin du milieu A") arrow(E) d arrow(l) + integral_"fin du milieu A"^"fin du milieu B" arrow(E) d arrow(l) $
$ arrow.double.r.l V(A) - V(B) = E_0/K_A(d_A) + E_0/K_B(d_B) $
$U_"stocké"/V = 1/2 epsilon_0 E^2$ ???
Calculer la capacité des condensateurs en série :
$ 1/C_"tot" = sum_"capacité du condensateur i" 1/C_i $
Calculer la capacité des condensateurs en parallèle :
$ C_"tot" = sum_"capacité du condensateur i" C_i $
== Circuits
=== Règle des noeuds (pour un noeud donné)
$sum_k i_k = 0$ \
$sum_n i_"in" = sum_n
i_"out"$
=== Règle des mailles (autour de chaque maille fermée)
$sum_k Delta V_k = 0$ \
On choisit un sens pour compter. \
On ajoute les tensions (de batterie par exemple) dans le sens dans lequel on va. \
On ajoute les résistances comme $plus.minus i_k dot R_k " "ohm$ en fonction du sens (si on compte dans le sens opposé au courant, on ajoute, sinon on enlève). donc le + des résistances est le - des tensions de batteries
=== Loi d'ohm
$V = R i$ (elle s'applique aux bornes d'un dipôle)
== Charger un condensateur
temps caractéristique d'un condensateur $tau = R C$.
On a qu'à l'état d'équilibre (quand le condensateur est chargé), le courant est nul :
$ C V = q arrow.r.double C (d V)/(d t) = (d q)/(d t) = i $
$ "donc " i = C (d q)/(d t) $

== Boot ROM
The Game Boy SoC includes a small embedded boot ROM, which can be mapped to the #hex-range("0000", "00FF") memory area. While mapped, all reads from this area are handled by the boot ROM instead of the external cartridge, and all writes to this area are ignored and cannot be seen by external hardware (e.g. the cartridge MBC).
The boot ROM is enabled by default, so when the system exits the reset state and the CPU starts execution from address #hex("0000"), it executes the boot ROM instead of instructions from the cartridge ROM. The boot ROM is responsible for showing the initial logo, and checking that a valid cartridge is inserted into the system. If the cartridge is valid, the boot ROM unmaps itself before execution of the cartridge ROM starts at #hex("0100"). The cartridge ROM has no chance of executing any instructions before the boot ROM is unmapped, which prevents the boot ROM from being read byte by byte in normal conditions.
#warning[
Don't confuse the boot ROM with the additional SNES ROM in SGB/SGB2 that is
executed by the SNES CPU.

#v(1em)
BOOT_OFF can only transition from #bin("0") to #bin("1"), so once #bin("1") has been written, the boot ROM is permanently disabled until the next system reset. Writing #bin("0") when BOOT_OFF is #bin("0") has no effect and doesn't lock the boot ROM.
]
)
]
The 1-bit BOOT register controls mapping of the boot ROM. Once #bin("1") has been written to it to unmap the boot ROM, it can only be mapped again by resetting the system.

==== DMG boot ROM
The most common boot ROM is the DMG boot ROM used in almost all original Game Boy units. If a valid cartridge is inserted, the boot ROM scrolls a logo to the center of the screen, and plays a "di-ding" sound recognizable by most people who have used Game Boy consoles.
This boot ROM was originally dumped by neviksti in 2003 by decapping the Game Boy SoC and visually inspecting every single bit.
==== MGB boot ROM
This boot ROM was originally dumped by Bennvenn in 2014 by using a simple clock glitching method that only requires one wire.
==== SGB boot ROM
This boot ROM was originally dumped by Cost<NAME> in 2009 by using an FPGA-based clock glitching method @costis_sgb.
==== SGB2 boot ROM
This boot ROM was originally dumped by gekkio in 2015 by using a Teensy 3.1 -based clock glitching method @gekkio_sgb2.
==== Early DMG boot ROM ("DMG0")
Very early original Game Boy units released in Japan (often called "DMG0") included the launch version "DMG-CPU" SoC chip, which used a different boot ROM than later units.
This boot ROM was originally dumped by gekkio in 2016 by using a clock glitching method invented by BennVenn.

= 1. Popiš základní konstrukci a vlastnosti mikroprocesoru (monolitu).
- mikroprocesory mohou být vyráběny pro řešení velmi specifických úloh, proto nelze jejich konstrukce a vlastnosti zcela zgeneralizovat - můžeme očekávat velké rozdíly mezi jednotlivými mikroprocesory
- převážně se používá harvardská koncepce:
- oddělená paměť pro program a data
- možnost použít jiné technologie (ROM, RWM) a nejmenší adresovatelné jednotky (12, 16, 32)
- procesory jsou obvykle RISC:
- kvůli jednoduchosti, menší spotřebě energie a menší velikosti
- typy paměti mikroprocesorů / monotlitických počítačů:
- pro data se používá _RWM-SRAM (Read-Write Static Random-Access Memory)_
- statické - jejich elementární paměťové buňky jsou realizovány klopnými obvody
- pro program se používají _ROM_ paměti:
- nejčastěji _EPROM_, _EEPROM_ a _Flash_ paměti + také _PROM_ (OTP - _One-Time Programmable_)
- některé mikroprocesory jsou ozačeny jako _"ROM-less"_
- nemají osazenou paměť pro program přímo na čipu _(On-Chip)_
- paměť pro program se připojuje k monolitu jako externí pamět
- např. Flash stick zapojený do _QSPI_ portu na _RP2040_
- paměť je organizována na:
- pracovní registry - obvykle jeden, dva
- ukládají aktuálně vypracovaná data
- jsou nějčastějšími operandy strojových instrukcí
- _"scratch-pad"_ registry:
- pro ukládání nejčastěji používaných dat
- část strojových instrukcí pracuje přímo s těmito registry
- paměť dat _RWM:_
- pro ukládání rozsáhlejších a méně používaných dat
- instrukční sada nedovoluje krom přesunových instrukcí s touto pamětí pracovat přímo
- musí se neprve přesunout do pracovních registrů
- počítač obsahuje také speciální registry:
- instrukční ukazatel _(Instruction Pointer)_ - ukazuje na instrukci v paměti, která se bude vykonávat
- instrukční registr - ukládá vykonávanou instrukci
- zásobník s návratovými adresami:
- buď je v paměti na vyhrazeném místě nebo jako samostatná paměť typu _LIFO_
- aby se vědělo kde je vrchol zásobníku je třeba mít _ukazatel na vrchol zásobníku_ (jako registr)
- zdroje synchronizace mohou být interní a externí:
- integrován přímo na čipu - není dobrá stabilita (i rozdílná tepota způsobí značné odchýlky)
- hodí se tam, kde není potřebna vazba na reálný čas
- externí generátory - často se používájí:
- krystal (křemenný výbrus) - dobrá stabilita, dražší (postavna na piezoelektrickém jevu - krystal při deformaci generuje el. napětí)
- keramický rezonátor - dobrá stabilita, dražší
- RC oscilátory - může být nepřesný, levný

- počáteční stav _RESET:_
- monolit je sekvenční obvod závislý nejen na instrukcích ale i na stavech a signálech
- aby počítač spolehlivě spustil program, musí být definován přesný počáteční stav (stav _RESET_)
- proto jsou implementovány inicializační obvody, které počítač do tohoto stavu dostanou
- ochrana proti rušení / nestabilitě / zničení obvodů:
- mechanické vlivy - náhodné rázy, vibrace - musí být _galvanicky_ oddělen od okolí
- program může vlivem okolí _"zabloudit"_ - tento problém řeší obvod _WATCHDOG_
- je to časovač, který je neustále inkrementován nebo dekrementován při běhu počítače
- přeteční nebo podtečení tohoto časovače způsobí _RESET_
- procesor tedy musí průběžně tento časovač vynulovávat
- pokud je ale _"zablouděný"_, tak tuto činnost nedělá $->$ přetečení $->$ _RESET_
- hlídání rozsahu napětí, ve kterém počítač pracuje:
- např. počítač funguje jen ve stanoveném rozmezí 3-6V
- dojde-li k tomu, že napětí napájení stoupne nad nebo klesne pod toto rozmezí $->$ _RESET_
- má integrovaný přerušovací podsystém: _(Interrupt Subsystem)_
- povoluje a zakazuje _interrupts_ - požadavky od periferií pro procesor, aby něco bylo vykonáno
- definuje způsob obsluhy _interruptů_
- zjišťuje zdroj a prioritu _interruptů_
- periférie: #emph[(viz další otázka more dyk)]
- vstupně-výstupní brány _(I/O gates)_
- sériové rozhraní _(SPI - Serial Peripheral Interface)_
- čítače a časovače _(Counter & Timer)_
- čítač vnějších událostí = inkrementuje se vnějším signálem
- časovač = registr, který je inkrementován hodinovým signálem
- A/D _(Analog to Digital)_ a D/A _(Digital to Analogue)_ převodníky _(ADC & DAC)_
#pagebreak()
= 2. Periférie monolitických počítačů - vybrat si a popsat.
== Vstupní a výstupní brány _(I/O gates)_
- nejčastějším a nejjednodušším rozhraním je paralelní brána neboli _port_
- skupina jednobitových vývodů - mohou nabývat log. 0 a log. 1
- většinou je 4-bit nebo 8-bit - předají se naráz (ne sériově)
- lze nastavit jednotlivé vývody jako vstupní a výstupní piny (vodiče)
- instrukční soubor s nimi pracuje buď jako s jednotlivými bity nebo celky
- tyto univerzální vývody umožňují komunikaci po sériové lince s vnějšími zařízeními
- např. lze jimi dynamicky ovládat LCD a LED
== Sériové rozhraní
- pro přenášení dat mezi periferními zařízeními a procesorem
- stačí minimální počet vodičů
- nízka přenosová rychlost
- delší časový interval mezi přenášenými daty - třeba data zakódovat a dekódovat (např. checkword u I2C rádiové komunikace)
- základní klasifikace komunikace (standardy):
- na větší vzdálenosti - RS232 nebo RS485 - mezi řídicím počítačem a podřízenými stanicemi
- uvnitř elektronikého zařízení - I2C (Inter-Integrated Circuit)
== Čítače a časovače
- čítač - registr o $N$ bitech
- čítá vnější události (je inkrementován vnějším signálem dle jeho náběžné nebo sestupné hrany)
- při jeho přetečení se předá _Interrupt Request_ do _Interrupt Subsystem_ mikropočítače
- jeho počáteční hodnota se nastaví programově
- je možné ho v libovolné chvíli od externího signálu odpojit a opět připojit
- časovač - čítač, který je inkrementován interním hodinovým signálem
- lze jim zajistit řízení událostí a chování v reálném čase
- při přeteční se automaticky předa _Interrupt Request_
- krom počáteční hodnot lze nastavit i předděličku

== A/D převodníky
- fyzikal. veličiny vstupují do mikropočítače v analog. formě (spojité)
- analog. signály mohou být
- napětí _(U - Voltage/Electric Tension)_, proud _(I - Current)_, odpor _(R - Resistance)_
- převede analog. signál do digital. formy
- základní typy:
- komparační A/D převodník
- A/D převodník s pomocí D/A převodem
- integrační A/D převodník
- převodník s RC článkem
== D/A převodníky
- převede hodnotu z digital. formy do analog. formy
- typy: PWM - Pulse Width Modulation & paralelní převodník
== RTC - real time clock
- hodiny reálného času
== Speciální periférie
- řízení dobíjení baterií
- dvoutonový multifrekvenční generátor a přijímač
- TV přijímač
- IR vysílač a přijímač
- řadiče LCD nebo LED
= 3. Vysvětlete PWM a kde se používá. Obrázek dobrovolný.
- realizován buď programovou implementací nebo dedikovaným obvodem
- číslicový signál na výstupu mikropočítače má obvykle 2 konstantní napěťové úrovně
- $U_0$ pro logickou 0 a $U_1$ pro logickou 1
- poměrem časů, kdy je výstup na log. 1 a log. 0, se moduluj z digitál. hodnoty analog. signál
- bude roven střední hodnotě napětí za dobu jedné dané periody
- čas $T_0$ - U je na úrovni $U_0$ neboli napětí reprezentujicí log. 0
- čas $T_1$ - U je na úrovni $U_1$ neboli napětí reprezentujicí log. 1
- perioda - $T = T_0 + T_1$
- střední hodnota napětí, $U#sub[PWM]$, je vypočitána vztahem:
$ U#sub[PWM] = U_0 + (U_1 - U_0) dot T_1/(T_0 + T_1) #text[nebo] U#sub[PWM] = Delta U T_1/T + U_0 $
- výstup se zesílí výstupním zesilovačem
- pro převod PWM pulsu na analog. veličinu se používá RC článek
- časová konstanta RC musí být výrazně větší než $T$ (toto způsobuje zpomalení)
- rozlišení výstup. signálu zavisí na počtu bitů komparovaných registrů (_PWM Registr_ a _Čítač_)
- využití: kontrola jasu LED diod, síly fénu, větráku, LCD pixelu
- princip u LED/LCD diod: _"Lidské oko nevnímá rychlé blikání jako blikání, ale jako jas."_

= 4. A/D a D/A převodníky a k čemu se používají. Nákres dobrovolný.
== A/D typy:
- *A/D komparační* - srovnání měřené analog. veličiny s referenčními hodnotami napětí a to v~určitém poměru (1 : 2 : 4 : 8 : 16 : 32 : 64 : 128 : 256) -- realizováno odporovou děličkou
- je to paralelní převodník
- $U#sub[INP]$ se chytne k nějakému komparátoru stejného nebo podobného napětí
- vybraný komparátor bude mít na výstupu 1 a ostatní 0
- kóder převede tento signál do binarního formátu
- velmi rychlé - s více komparátory roste přesnost
#figure(
caption: "Komparační A/D převodník - odporová dělička",
image("monolity/image4.png", width: 33%)
)
- *A/D převodník s D/A převodem* - jeden komparátor, mění se referenční hodnota
- podle způsobu řízení ref. hodnoty, dělíme na sledovací a aproximační
- sledovací:
- najde měřenou hodnotu postupnou inkrementací a dekrementací ref. hodnoty o jeden krok
- je pomalý - vhodný pro měření pomalu měnicích se veličin - teplota, vlhkost
- aproximační:
- ref. hodnota je na počátku ve středě mezi minimem a maximem měřitelného rozsahu napětí
- podle výsledku komparátoru měřené hodnoty s ref. hodnotou se vždy posune ref. hodnota nahoru nebo dolů o polovinu zbytku intervalu
- složitost algoritmu je $O(log_2n)$, kde $n$ je počet měřitelných hodnot -- jde o binární vyhledávání
#figure(
caption: "A/D převodník s D/A převodem",
image("monolity/image5.png", width: 40%)
)
#pagebreak()
- *integrační A/D převodník:*
- integrátor integruje vstupní napětí $U#sub[INP]$ po pevně stanovenou dobu $T_1$ do $U_1$
- po skončení $T_1$
- se přepne vstup integrátoru $P_1$
- integruje se dle ref. napětí $U_R$ opačné polarity k $U#sub[INP]$
- nyní se po dobu $T_2$ integruje $U_R$ dokud $U_1$ neklesne na $0V$
- doba $T_2$ je závislá na $U_1$ na konci $T_1$ - z ní lze získat hodnotu měřeného napětí:
$ U#sub[INP] = -(T_2/T_1 dot U_R) $
- *A/D převodník s RC článkem:*
- na vstupu měří odpor $R#sub[INP]$ ne napětí - např. tenzometr, termistor
- princip:
- necháme nabíjet kondenzátor přes ref. odpor $R#sub[REF]$ dokud $U_C$ v kondenzátoru nedosáhne $U#sub[CC]$
- teď necháme konden. $C$ vybíjet
- přes stejný odpor dokud $U$ v konden. neklesne na hodnotu $U#sub[KOMP]$
- přičemž měříme čas vybíjení $T#sub[REF]$
- to samé uděláme s měřeným odporem $R#sub[INP]$ - získáme tím čas vybíjení $T#sub[INP]$ (na obrázku $T_s$)
- hodnotu vstupního napětí, $R#sub[INP]$, získáme vztahem:
$ R#sub[INP] = R#sub[REF] dot (T#sub[INP])/(T#sub[REF]) because (R#sub[INP])/(R#sub[REF]) = (T#sub[INP])/(T#sub[REF]) $

== D/A převodníky
- *PWM* (viz otázka na PWM)
- *paralelní D/A převodník*
- je rychlý
- založeny na přímém převodu digitální hodnoty na analog. veličinu
- základem je odporová síť, na níž se vytvářejí částečné výstupní proudy:
- váhově řazené hodnoty - rezistory s odpory v poměrech 1 : 2 : 4 : ... : 64 : 128
- R-2R - stačí rezistory s odpory R a 2R
- digitalní hodnota přepína přepínače pod 2R rezistory
- výstupem je el. proud $I_A$ a jeho komplementární (znegovaný) proud $I_B$

= 5. I2C - co to je, jak funguje, kde se používá a naskreslit.
- je sériová komunikační sběrnice
- umožňuje přenos dat mezi různými zařizeními
- byla vyvinuta firmou Phillips
- stala se populární mezi integrovanými obvody _(IC - integrated circuit)_ a perifer. zařizeními
- pro svou jednoduchost a snadnou rozšířitelnost
- funguje na základě 2 obousměrných vodičů (ty mohou nabývat hodnot log. 0 a log. 1):
- SDA _(Serial Data Line)_ - pro přenos dat mezi zařizeními, data jsou zasílana sériově po bitech
- SCL _(Serial Clock Line)_ - pro synchronizaci přenosu
- funguje ve formě přenosu dat mezi _"Master"_ a _"Slave"_ zařizeními
- *_Master_* - zodpovědný za řízení komunikace, inicializuje přenos
- *_Slave_* - řízení od _"Master"_ přijímá a vykoná (vykoná funkci / poskytuje data)
- princip fungování:
- v klidovém stavu obě na log. 1
- komunikace se zahajuje řídicím signálem _START_ - přivedením _SDA_ na 0, hned po ní _SCL_ na 0
- ukončí se řídicím signálem _STOP_ - _SCL_ na log. 1 a hned po ní SDA na log. 1
- musíme na začátku komunikace adresovat _"Slave"_ zařízení, se kterým chceme komunikovat, a zadat směr komunikace - zda chceme číst _(RD)_ od nebo zapisovat _(WR)_ do _"Slave"_ zařízení:
- po _SDA_ předáme adresu zařízení s řídicím bitem _RD_ nebo _WR_ jako 1 byte dat
- 7 bitů slouží pro adresování zařízení a 1 bit (LSB) pro směr komunikace
- pokud adresované zařízení zaznamená, vyšle signál _ACK_ (log. 0) po datovém vodiči
- zápis/write - posílame byte postupně po bitech - po každém bytu dat musí _"Slave"_ vyslat _ACK_
- čtení/read - očekaváme data od zařízení - po každém bytu, který přijmem, vyšlem _ACK_

7. Fyzikální popis HDD čtení, zápis a nákres. Vysvětlit podélný a kolmý zápis.

+ Čtení CD - princip a obrázek.
= 7. Fyzikální popis HDD - čtení, zápis a nákres. Vysvětlit podélný a kolmý zápis.
- médium HDD _(Hard Disk Drive)_, na kterém se data ukládají, je feromagnetická vrstva nanesena na plotnu disku (většinou ze skla / slitiny hliníku)
- pracuje s magnetickým záznamem - tím zaznamená data
- feromagnetická vrstva dokáže uchovat magnetická pole
- záznamová/zapisovací hlava - jádro s úzkou štěrbinou (1μm) a navlečenou cívkou
- vrstva feromagnetická je trvale zmagnetována záznamovou hlavou
- v bodu dotyku hlav (zapisovací a čtecí) nebo v nepatrné vzdálenosti s médiem je štěrbina
== Zápis na disk
- při průchodu el. proudu cívkou proudí magnet. tok jádrem
- jádro v je části, kde je nejblíže záznamové vrstvě, přerušeno úzkou štěrbinou vyplněnou nemagnetickou látkou (nejčastěji bronz) nebo "ničím" (vzduchem)
- v místě štěrbiny dochází k magnatickému stínění jádra a následnému vychýlení indukčních čar z jádra cívky do feromagnetické vrstvy disku
- měněním směru el. proudu v cívce se mění směr magnet. toku jádrem i štěrbinou a tím smysl magnetizace aktivní vrstvy
== Čtení z disku
- při čtení se disk pohybuje stejným směrem konstantní rychlostí
- na aktivní feromagnetické vrstvě jsou místa magnetizované tím či oním směrem - mezi nimi jsou místa magnetického přechodu - tzv. _"magnetické rezervace"_
- právě ony představují zapsanou informaci
- změny mag. polí na feromag. vrstvě způsobují napěťové impulsy na svorkách cívky čtecí hlavy
- impulsy jsou následovně zesíleny elektrickými zesilovači

== Podélný zápis (longitudinální zápis)
- způsob, jakým byla data tradičně zapisována na pevné disky
- magnetická pole, která reprezentují jednotlivé bity dat, jsou orientována podél povrchu disku
- data jsou zapsána v podélných stopách na disku, které jsou rozděleny na sektory
== Kolmý zápis (perpendikulární zápis)
- modernější způsob zápisu na pevný disk, který umožňuje vyšší kapacitu a rychlost zápisu
- při kolmém zápisu jsou magnetická pole orientována kolmo na povrch disku
- to umožňuje menší a hustší záznam dat na povrchu disku - zvyšuje kapacitu pevného disku
- při kolmém zápisu jsou magnetická pole stabilnější a méně náchylná k rušení
= 8. Popište a nakreslete stavbu pevného disku. Nechtěl podélný a kolmý zápis.
- je to uzavřená jednotka v počítači používaná pro trvalé ukládání dat (nevolatilní paměť)
- pouzdro chrání disk před nečistotami a poškozením
- obsahuje nevýjmutelné pevné plotny diskového tvaru (slitiny hliníku / sklo) - odtud _pevný_ disk
- části pevného disku:
- plotny disku
- hlavy pro čtení a zápis
- vzduchové filtry
- pohon hlav
- pohon ploten disku
- řídící deska (deska s elektronikou)
- kabely a konektory
#pagebreak()
== Geometrie disku
- uspořádání prostoru na disku - počet hlav (zapisovací a čtecí), cylindrů a stop
- data jsou na disk ukládána v bytech
- byty jsou uspořádány do skupin po 512 bytech (nové 4KiB) zvané sektory
- sektor je nejmenší jednotka dat, kterou lze na disk zapsat nebo z disku přečíst
- sektory jsou seskupeny do stop
- stopy jsou uspořádány do skupin zvaných cylindry nebo válce
- předpokladem je, že jeden disk má nejméně dva povrchy (dolní a horní plocha plotny)
- systém adresuje sektory na pevném disku pomocí prostorové matice cylindrů, hlav a sektorů

caption: "Geometrie pevného disku a popis plotny"
)
=== Stopy
- každá strana každé plotny je rozdělena na soustředné stopy (kružnice)
- protože povrchů i hlav je několik, je při jedné poloze hlav přístupná na každém povrchu jedna stopa - pro vybrání jedné stopy stačí elektronicky přepínat hlavy
=== Cylindry
- pevné disky mají více ploten (disků), umístěných nad sebou, otáčejících se stejnou rychlostí
- každá plotna má dvě strany (povrchy), na které je možno data ukládat
- diskové hlavy nemohou být vystavovány nezávisle (jsou pohybovány společným mechanismem)
- souhrn stop v jedné poloze hlav se nazývá cylindr (válec)
- počet stop na jednom povrchu je totožný s počtem cylindrů
- z tohoto důvodu většina výrobců neuvádí počet stop, ale počet cylindrů
=== Sektory
- jedna stopa je příliš velkou jednotku pro ukládání dat (100KiB či více bytů dat)
- stopa se rozděluje na několik očíslovaných částí nazývané sektory
- můžeme si je představit jako výseče na plotně
- je to nejmenší adresovatelná jednotka na disku - na rozdíl od hlav nebo cylindrů, číslujeme od 1
- její velikost určí řadič při formátování disku
- na začátku sektoru je hlavička identifikující začátek sektoru a obsahující jeho číslo
- konec - tzv. zakončení sektoru - pro ukládání kontrolního součtu _(ECC - Error Correcting Code)_
- slouží ke kontrole integrity uložených dat
- jednotlivé sektory se oddělují mezisektorovými mezerami - zde není možné data uložit
- proces čtení sektoru se skládá ze dvou kroků:
- čtecí a zápisová hlava musí přemístit nad požadovanou stopu
- potom se čeká, až se disk natočí tak, že požadovaný sektor je pod hlavou, a pak probíhá čtení
- přemístění hlavy obvykle zabere nejvíce času
- nejrychleji se tedy čtou soubory, jejichž sektory jsou všechny na stejné stopě a stopy jsou umístěny nad sebou v jednom cylindru
= 9. Čtení CD - princip a obrázek.
- jako materiál CDčka se používá polykarbonát, strana se záznamem je pokryta reflexní vrstvou a ochranným lakem
- záznam je v podobě pitů (prohlubně) a polí (ostrůvky) na disku
- čtení zaznamenaných dat probíhá způsobem, kdy laser v přehrávači CD snímá z povrchu disku zaznamenaný vzor
- mechanika CD:
- laser je umístěn rovnoběžně s povrchem disku
- paprsek je na disk odrážen zrcadlem přes dvě čočky
- lze velmi úzce zaostřit na malé plochy disku CD-ROM
- fotodetektor pak měří intenzitu odraženého světla
- laser nemůže poškodit nosič a na něm uložená data
- při čtení se paprsek odráží od lesklého povrchu disku CD-ROM a nijak ho nepoškodí
- mechanismus laseru je od disku asi jeden milimetr

)
- čtení dat z CD média probíhá za pomocí laserové diody
- emituje infračervený laserový paprsek směrem k pohyblivému zrcátku
- čtenou stopu přesune servomotor pod zrcátko na základě příkazů z mikroprocesoru
- po dopadu paprsku na jamky a pevniny, resp. pity a pole, se světlo láme a odráží zpátky
- dále je zaostřováno čočkou, nacházející se pod médiem
- od čočky světlo prochází pohyblivým zrcátkem - reflexní zrcadlo
- odražené světlo dopadá na fotocitlivý senzor - fotodioda
- převádí světelné impulsy na elektrické
- samotné elektrické impulsy jsou dekódovány mikroprocesorem a předány do počítače ve formě dat v binárním formátu

= 10. Popište a nakreslete technologii LCD - výhody, nevýhody, rozdíl mezi pasivním a aktivním.
- LCD - _Liquid Crystal Display_
- používá tekuté krystaly k zobrazení jednotlivých pixelů
- v základě jsou dvojího typu:
- TN-TFT - _Twisted-Nematic Thin-Film-Transistor_
- IPS - _In-Plane-Switching_
== Princip TN-TFT LCD _(Twisted-Nematic Thin-Film-Transistor LCD)_
1. světlo projde polarizačním filtrem a polarizuje se
+ projde vrstvami tekutých krystalů (uspořádaných do šroubovice) - světlo se otočí o 90°
+ projde druhým polarizačním filtrem (které je otočené o 90° proti prvnímu)
- klidový režim (bez napětí) - propouští světlo
- přivede-li se napětí, krystalická struktura (šroubovice) se zorientuje podle směru toku proudu
- světlo projde prvním polarizačním filtrem, neotočí se $->$ je definitivně zablokováno
- střídáním proudu lze určit intenzitu propouštěného světla
- nutno podsvítit bílým světlem (elektroluminiscenční výbojky, LED, OLED)
- vrstva krystalů je rozdělená na malé buňky stejné velikosti, tvořící pixely
== Princip IPS LCD _(In-Place-Switching LCD)_
- podobné TN
- krystaly jsou uspořádány v rovině
- elektrody jsou po obou stranách buňky v jedné vrstvě
- přivede-li se napětí, krystaly se začnou otáčet ve směru elek. proudu - otočení celé roviny krystalů
- tím otočí i světlo, které jím procházelo, a propustí se druhým polarizačním filtrem
- klidový stav - světlo neprochází přes 2. pol. filtr - "nesvítí"

#pagebreak()
== Barevné LCD
- každý pixel se skládá ze 3 menších bodů (subpixelů) obsahující Red, Green, Blue filtr
- propouštěním světla do barevných filtrů a složením barev dostaneme výslednou barvu pixelu
#figure(
caption: [Barevný LCD - průchod bílého světla přes barevné filtry],
image("zob_jednot/image3.png", width: 50%)
)
== Pasivní matice LCD
- obsahuje mřížku vodičů, body se nacházejí na průsečících mřížky
- při vyšším počtu bodů narůstá potřebné napětí → rozostřený obraz, velká doba odezvy (3 FPS) nevhodné pro hry, filmy, televizi atd.
- z jediného rosvíceného bodu se rozbíhají postupně slábnoucí vertikální a horiznontální čáry
- používá se v zařízeních s malým displejem (hodinky)
== Aktivní matice LCD
- každý průsečík v matici obsahuje svůj tranzistor nebo diodu - řeší řídicí činnost daného bodu
- pomocí tranzistoru ve spolupráci s kondenzátorem lze rychle a přesně ovládat svítivost $forall$ bodu
- TF _(Thin Film)_ tranzistory izolují jeden bod od ostatních - eliminace "čár" na pasivním LCD

= 11. Popište a nakreslete technologii OLED - výhody, nevýhody.
- hlavním prvkem - organická dioda emitující světlo _(Organic Ligh Emitting Diode)_
- po přivedení napětí na obě elektrody se začnou eletrony hromadit v org. vrstvy blíže k anodě
- anoda přítahuje elektrony
- tím vznikají "díry" - kladné částice / absence elektronů - ve _"vrstvě pro přenos děr"_
- díry představující kladné částice se hromadí na opačné straně blíže ke katodě
- katoda odpuzuje elektrony
- tím se ve _"vrstvě pro přenos elektronů"_ hromadí elektrony
- v organické vrstvě _("emisní vrstvě")_ začně docházet ke "srážkám" mezi elektrony a dírami
- elektrony zaplňí "díry"
- to způsobí jejich vzájemnou eliminaci - *rekombinace*
- doprovází vyzáření energie ve formě fotonu, které vnímáme jako světlo
- měněním napětí, které do diody přivádíme, způsobuje změnu jasu diody
- čím větší napětí, tím víc vzniká "děr" $->$ vyšší výskyt rekombinace $->$ více vyzářených fotonů

- stejný princip jako aktivní / pasivní LCD
- body organizovány do pravoúhlé matice
- pasivní - každá OLED je aktivována dvěma na sebe kolmými elektrodami, procházejícími celou šířkou a výškou displeje

= 12. Popsat E-ink - jaké má barevné rozmezí, výhody a nevýhody.
- technologii E-ink používají zařízení EPD (Electronic Paper Device)
- EPD nepotřebují elektrický proud pro statické zobrazování
- inkoust tvořen mikrokapslemi (\~ desítky-stovky µm)
- částice v kapslích se přitahují k elektrodě s opačnou polaritou
- roztok - hydrokarbonový olej (díky jeho viskozitě vydrží částice na míste i po odpojení napájení)
- "stavba" kapsle:
- černé záporné částice jsou z uhlíku -- C
- bíle kladná částice z oxidu titaničitého -- TiO#sub[2]
- obal z oxid křemičitého -- SiO#sub[2] -- a tenké vrstvy polymeru
- jako elektoforetický roztok (elektricky separovatelný) se používá hydrokarbonový olej
- k pohybu částic je potřeba proud \~desítky nA při napětí 5-15 V
- pro barvy se používají barevné filtry (stejně jako u LCD)
- barevná hloubka - je závislá na počtu elektrod na jeden zobrazovací bod
- $(2^n)^c$ kde $n$ je počet elektrod a $c$ počet barevných složek (např. $(2^4)^3 = 16^3 = 4096$)

= 14. Popište na RISC procesoru zřetězené zpracování instrukcí, jaké má chyby a jak se řeší.
- procesor je sekvenční obvod
- vstup - instrukce a data z paměti
- výstup - výsledky uloženy do paměti
- instrukce jsou vždy zpracovány stejným způsobem v několika fázích, např.:
1. *VI* -- Výběr instrukcí z paměti (Instruction Fetch)
+ *DE* -- Dékódování instrukce (Instruction Decoder)
+ *VA* -- Výpočet adresy operandů (Operand Address Calculation)
- získá se adresa operandů, se kterou instrukce pracuje
+ *PI* -- Provedení instrukce (Instruction Execution)
+ *UV* -- Uložení výsledku zpět do paměti (Store Result)
- instrukce projde všemi těto fázemi - pokud by trvala každá fáze 1 stroj. cyklus, tak by se 1 instrukce vykonala za 5 stroj. cyklů
- instrukce $I_2$ se nemůže vykonat, když procesor zpracovává inst. $I_1$
- osamostatněním jednot. fází vlastními obvody - je možné instr. zřetězit
- zatímco *VI* vybíra instrukci z paměti, může *DE* dekédovat instr., kterou před jedním stroj. cyklem vybrala *VI* z paměti
- teoreticky se tím zvýší výkon o násobek hloubky zřetězení
- tomuto zrychlení avšak zabraňují podmíněné skoky, datové a strukturální hazardy
- podmíněné skoky:
- neví se, kdy se skok provede a kdy ne
- adresa IP se změní - rozpracované instrukce jsou neplatné - musí se _flushnout_ fronta instrukcí - *_problém plnění fronty_*
- existují mechanismy jak tomu předcházet
- predikce skoku (_Brach Prediction_)
- jednobitová - v instrukci skoku je 1 bit vyhrazen pro _flag_, který předpovídá, jestli se bude či nebude skákat (přepíná se po jednom vykonání a nevykonání skoku)
- dvoubitová - v instrukci jsou vyhrazeny 2 bity (přepína se až po dvou konsekutivních vyhodnocení skoku)
- zpoždění skoku - pokud možno, vykonají se instruce jiné ještě před instrukcí skoku (i přesto, že jim v programu instrukce skoku předchází)
- buffer s pamětí skoků (_BTB -- Branch Target Buffer_) - pamatuje si tisíce tzv. _target_ adres skoků
- strukturální hazardy:
- pomalé sběrnice a registry mezi jednotkami jednot. fází
- musí se koordinovat přístup ke sběrnici
- datové hazardy:
- instrukce potřebuje výsledky od instrukce, která ještě nebyla vykonána

= 15. Popište na RISC procesoru zřetězené zpracování instrukcí a jak nám pomůže predikce skoku.
- viz 14. otázku - jak funguje zřetězené zpracování instrukcí
- typy řešení predikcí skoků - _jednobitová, dvoubitová, BTB_:
- _jednobitová_ predikce:
- ve formátu instrukce skoku se vyhradí jeden bit pro uložení stavu _flagu_ predikující, zda se skok vykoná či ne
- buď se _flag_ nastaví _staticky_ programátorem/kompilátorem _(hard coded)_
- nebo se nastavuje při běhu programu _dynamicky_ dle výsledku podmínky předcházejicího skoku
- v cyklu k selhání predikce dojde vždy 2x - první a poslední iterace
- _dvoubitová_ predikce:
- vyhradí se dva bity - 4 možné hodnoty/stavy
- funguje jako stavový automat se 4 stavy - NE = nebude se skákat, ANO = bude se skákat
- 00 _(ANO)_ - stálý stav skákání
- 01 _(ANO)_ - jeden neprovedený skok
- 10 _(NE)_ - jeden provedený skok
- 11 _(NE)_ - stálý stav "neskákání"
- přechody $a$ a $n$ ukazují jestli se naposledy skákalo či ne
- v cyklu se omezí počet selhání na jeden
#figure(
caption: "Dvoubitová predikce - čtyřstavový automat",
image("RISC/image3.png", width: 70%)
)
- _BTB (Branch Target Buffer):_
- tabulka s uloženými adresami provedených podmíněných skoků
- ať už jednobitová nebo dvoubitová predikce
- většinou implementována přímo na procesorech
- může mít až tisíce položek
#pagebreak()

- viz předchozí otázky - popsaný datové a strukturální hazardy, problematika zpracování podmíněných skoků
= 17. Popiš základní konstrukci a vlastnosti mikroprocesoru RISC.
- mají malý instrukční soubor
- vývojová větev RISC vyvinula řadu zásadních kritérií, charakterizujících metodiku návrhu nejen procesoru, ale i celého počítače
- procesoru se má přenechat jenom ta činnost, která je nezbytně nutná
- další potřebné funkce přenést do architektury počítače, programového vybavení a kompilátoru
- výsledkem návrhu jsou zejména tyto vlastnosti:
- jedna instrukce dokončena každý strojový cyklus
- mikroprogramový řadič (software) nahrazen rychlejším obvodovým řadičem (fyz. dráty)
- zřetězené zpracování instrukcí
- počet instrukcí a způsobů adresování je malý
- data jsou z hlavní paměti vybírána a ukládána výhradně pomocí dvou instrukcí LOAD a STORE
- instrukce mají pevnou délku a jednotný formát
- použit vyšší počet registrů
- složitost se z technického vybavení přesouvá částečně do optimalizujícího kompilátoru
- všechny uvedené vlastnosti tvoří dobře promyšlený a provázaný celek:
- navýšení počtu registrů & omezení komunikace s pamětí na dvě instrukce LOAD a STORE
- ostatní instrukce nemohou používat pam. operandy - třeba mít v procesoru více dat
- zřetězené zpracování & formát instrukcí
- jednotná délka instrukcí dovoluje rychlejší výběr instrukcí z paměti
- zajišťuje lepší plnění fronty instrukcí
- jednotný formát zjednodušuje dekódování instrukcí
- výsledné počítače vytvořené podle těchto pravidel přinášejí výhody pro uživatele i pro výrobce
- zkracuje se vývoj procesoru - již první realizované čipy fungují správně (většinou)
- architektura RISC má i své nedostatky
- nutný nárůst délky programů - tvořený omezeným počtem instrukcí jednotné délky
- zpomalení, které by z toho mělo nutně plynout, se ale v praxi nepotvrdilo
- procento instrukcí, které muselo být rozepsáno, je malé
- většina výrobců CISC procesorů se uchýlila při výrobě procesorů k realizaci stále většího počtu vlastností arch. RISC

- #underline[elementární buňky:]
- DRAM _(Dynamic RAM)_ - náboj v kondenzátoru drží bit dat
- postupně se vybíjí - musí se _refreshnout_, jinak se data ztratí
- proto název dynamický
- SRAM _(Static RAM)_ - stav klopného obvodu drží bit dat
- dokud je zapojený proud, udržuje data
- netřeba žádný _refresh_ - proto název statický
- PROM - přepálené pojistky _(fuse blowing)_
- přeplené a nepřepálené pojistky reprezentují log. 0 a log. 1 - jeden bit dat
- EPROM _(Erasable Programmable ROM)_, EEPROM _(Electrically EPROM)_, Flash Memory
- tranzistor s plovoucím hradlem (floating-gate transistor)
- #underline[uchování dat po odpojení napájení:]
- _Volatile_ - neuchovají data, musí se nepřetržitě napájet, bývají rychlejší
- hlavní operační paměti DRAM _("ramka")_ a SRAM _("cache" paměti)_
- _Non-Volatile_ - uchovají data i po odpojení, nezávislé na napájení, bývají pomalejší
- xxROM paměti - pro bootloadery, BIOSy, Firmware atd.
- SSD _(Solid State Drive)_, HDD _(Hard Disk Drive)_ - externí paměti, hlavní uložiště

= 21. Jak funguje DRAM, nakresli. Napiš stručně historii.
== Stručná historie
- 50. léta 20. st. - bubnové paměti, feritová jádra
- 70. léta 20. st. - bublinové paměti
- 1969 - polovodičová technologie MOS
- 1970 - Dynamický RAM
- 1971 - Statický RAM
== DRAM
- informace uložena ve formě náboje v kondenzátoru
- nabitý = log. 1
- vybitý = log. 0
- jedna "_buňka_" dynamické paměti je sestavena z kondenzátoru $C$ a tranzistoru $T$ (jako el. _switch_)
- kapacita $C$ je velmi malá (jednotky femtoFarad) - časem ztrácí napětí (proud teče do/ven z $C$)
- nutný častý _refresh_ (občerstvení), aby si uchovala svou informaci (každých \~10 ms)
- provede se pro celý řádek při každém čtení buňky z tohoto řádku

),
caption: "Paměťové buňky v DRAM a Organizace paměťových buněk v DRAM"
)
- buňky jsou umístěny ve čtvercové matici (matic je vedle sebe naskládaných více)
- adresování buňky probíha ve dvou krocích:
1. vybere se řádek _(ROW)_ buňky pomocí _Row Decoder_
- aktivuje vodič (_wordline_) daného řádku vedoucího z _Row Decoderu_
2. vybere se sloupec _(COL)_ buňky pomocí _Column Decoder_
- informace uložena v této buňce (1 nebo 0) se pošle do _I/O bufferu_ přes vodič _(bitline)_ vedoucí z _Column Decoderu_
- rozdělení adresování na dva dekódery (_Row_ a _Column_) znamená, že stačí poloviční počet vodičů pro adresování - např. pro $2^20$ buňek stačí $10$ vodičů - $2^10 dot 2^10 = 2^20$
- sdílení stejných vodičů pro přenos částečné informace se nazývá _"multiplexing"_
- musíme ale zavést dva řídicí signály:
- _RAS_ (Row Access Strobe) a _CAS_ (Column Access Strobe)
- proto aby se vědělo jakému dekóderu je adresa určena
- _DRAM_ paměť je organizována tak, že se při čtení/zápisu předá více než jeden bit - to určí počet bitů v _I/O bufferu_
- #underline[princip čtení] z _DRAM_:
- _address buffer_ příjme adresu, kterou poskytlo CPU
- adresa je rozdělena na adresu řádku a sloupce
- pošle se do _address buffer_ jedna po druhé - adresní _multiplexing_
- _multiplexing_ je kontrolován _RAS_ a _CAS_ řídicími signály
- pokud se pošle adresa řádku aktivuje se předtím _RAS_ signál
- pokud adresa sloupce tak _CAS_ signál
- _address buffer_ pošle (na základě _RAS_ a _CAS_ signálu) částečnou _multiplexovanou_ adresu buď _Row Decoderu_ nebo _Column Decoderu_
- vyšle se _READ_ řídicí signál, data adresované paměťové buňky se zesílí el. zesilovači a předá do _I/O bufferu_ - výstupní data
- #underline[princip zápisu] je obdobný čtení z _DRAM_:
- probíha klasicky vybrání řádku a sloupce
- namísto signálu _READ_ se ale vyšle _WE_ _(Write Enable)_ řídicí signál
- do _I/O bufferu_ se zapíšou data, která se mají uložit
- data z _I/O bufferu_ se zesílí a tím přepíšou adresované buňky
#pagebreak()
= 22. Hierarchie paměti, popsat a zakreslit do <NAME>.
- v počítači se používají různé typy paměti
- důvody jsou ekonomické, technické a praktické
- kdyby existoval typ paměti, který je levný, nevolatilní, umožňuje náhodný přístup k datům a je rychlý, nepotřebovalo by se vytvářet tolik typů pamětí - taková technologie však zatím neexistuje
- bere se v potaz kompromis mezi cenou, rychlostí a kapacitou

- paměti uspořádaný podle ceny, rychlosti a kapacity
- každá úroveň paměti tvoří vyrovnávací _(cache)_ paměť té pod ní
- data z OpMem jsou částečně v LCache
- data z SSD jsou částečně v OpMem atd.

+ Popište a nakreslete harvardskou architekturu, popište rozdíly, výhody a nevýhody oproti von Neumann. Na obrázku vyznačte části, které mají a nemají společné. Která architektura je podle vás lepší a proč?
= 23. Popiš základní konstrukci a vlastnosti počítače.
- všechny počítače pochází z von Neumannovy základní koncepce - počítač je řízen obsahem paměti
- představen v roce 1945 - EDVAC _(Electronic Discrete Variable Automatic Computer)_
- von Neumann stanovil kritéria a principy, které musí počítač splňovat:
1. generický design - struktura počítače je nezávislá na typu řešené úlohy
+ počítač se programuje obsahem paměti
+ strojové instrukce a data jsou uloženy v téže paměti - stejný přístup do paměti
- rozdílné je to u harvardské koncepce - samostatná paměť pro program _(instrukce)_ a data
+ paměť je rozdělena do buněk stejné velikosti - jejich pořadová čísla jako adresy
+ následujicí krok je závislý na tom předchozím
+ program je sekvence instrukcí, které se sekvenčně vykonají
+ změna pořadí provádění instrukcí se provádí za pomocí skoků ((ne)podmíněný)
+ pro rezprezenaci instrukcí, dat, čísel, znaků se používá dvojková soustava
+ počítač se skládá z řídicí a aritmeticko-logické jednotky (dnes jako celek _CPU_ - centrální procesní jednotka), paměti a _I/O_ jednotek
= 24 Jak funguje počítač a jak se vykonávají skokové instrukce.
- počítač je programován obsahem paměti
- instrukce se vykonávají sekvenčně
- každy krok závisí na tom předchozím
- procesor _(CPU)_ je sekvenční obvod - vstupem jsou strojové instrukce z paměti
- má svou vlastní rychlou paměť pro ukládání výsledku instrukcí - _registry_
- instrukční ukazatel _(IP - Instruction Pointer)_ - někdy jako _PC_ _(Program Counter)_
- ukazuje na instrukci v paměti, která má být vykonána
- pomocí něj _"fetchne"_ insrukci z paměti a vykoná jí
#figure(caption: "Princip fungování počítače",image("arch_poc/arch_poc1.png", width: 50%))
- následně se inkrementuje o délku právě provedené instrukce
- pokud instrukce potřebuje data z paměti, vyžádá si je _CPU_ stejným způsobem jako instrukce
- výsledek se uloží do paměti přes sběrnici (nebo ještě zůstává v registrech)
- skokové instrukce jsou dvojího typu - podmíněné a nepodmíněné
- když _CPU_ zpracovává nepodmíněný skok, nastaví svůj _IP_ na místo kam se skáče
- následné instrukce se _fetchují_ od této adresy
- u podmíněného skoku, _CPU_ vyhodnotí, jestli se bude skákat
- na základě stavu _flags_ registru, který uchovává aktuální stav procesoru
- až potom se nastaví _IP_ na cílovou _(target)_ adresu (skočilo se) nebo
- se pouze inkrementuje o délku právě vykonané instrukce (neskočilo se)
= 25. Popište a nakreslete architekturu dle <NAME>ann. Napište jeho vlastnosti, výhody a nevýhody.
#figure(caption: [Počítač dle _von Neumann_], image("arch_poc/arch_poc2.png", width: 50%))
- pro vlastnosti viz otázku 21
- CPU _(Central Processing Unit)_ - sdružené řídicí a výpočetní jednotky
- paměť - společná pro program i data
- vstup/výstup _(Input/Output)_ - pro externí zařízení
- sběrnice - sdružené datové a řídicí signály, propojuje _CPU_, paměť a _I/O_
- #underline[výhody]:
- rozdělení paměti pro program a data si rozhodne sám programátor
- řídicí jednotka přistupuje do paměti pro data i instrukce jednotným způsobem
- jedná sběrnice znamená jednodušší design a výrobu
- #underline[nevýhody:]
- společné uložení dat a programu může vést při chybě k přepsání valstního programu
- jediná sběrnice je _bottleneck_ (úzké místo) - nižší proputnost dat
#pagebreak()

#figure(image("arch_poc/arch_poc3.png", width: 70%), caption: [Počítač dle harvardské architektury])
- vznikla pár let potom, co <NAME> představil svou koncepci
- vymyslel jej odborný tým z Harvardsé univerzity
- od <NAME> se moc neliší - snažila se vyřešit její nedostatky
- pouze oddělení paměti na dvě samostatné - pro program a pro data
- pro vlastnosti viz 21. otázku - jsou až na rozdělení paměti stejné
- #underline[výhody:]
- oddělení paměti pro data a program
- program nemůže přepsat sám sebe
- paměti mohou být vytvořeny odlišnými technologiemi
- jiná velikost nejmenší adresovací jednotky
- např. ROM pro program a RWM pro data
- dvě sběrnice zvyšují propustnost - souběžné přistupování pro data i instrukce
- #underline[nevýhody:]
- dvě sběrnice - vyšší nároky při vývoji řídicí jednotky + zvyšuje náklady pro výrobce
- nevyužitá část paměti nelze využít - program nemůže být v paměti pro data a naopak

+ Popiš DMA blok a nakresli schéma DMA řadič v architekuře dle von~Neumanna.
== Technika _I/O_ brán
- _I/O gate_ (vstupně-vystupní brány)
- obvod zprostředkovávajicí předávání dat mezi sběrnicí počítače a perifériemi
- základem je _latch register_ (záchytný registr) s _tří-stavovým výstupem_ (three-state, tří-stavový budič sběrnice)
+ _Inactive_ stav - stav vysoké impedance, "Do not disturb"
+ _Input_ stav - periférie data přijímá
+ _Output_ stav - periférie vysíla data
- má ho každý tzv. budič sběrnice (každé zařízení/periférie, které je napojené na sběrnici)
- jeho stav dává vědět ostatním zařízením/periferiím, jestli na sběrnici data zapisuje _(Output)_, čte _(Input)_ nebo s ní momentálně nekomunikuje _(Inactive)_
- možnost použít brány s pamětí _(buffer)_
- ten je potřebný při obostranném (úplného) korespondenčním režimu
- v následujicích otázkách jsou popsány některé druhy technik _I/O_ brán
= 27. Komunikace se semafory a bez semaforů (indikátorů). Nakresli aspoň jedním směrem.
== Technika nepodmíněného vstupu a výstupu _(bez semaforu/indikátoru)_
#figure(image("komunikace/image1.png", width: 60%), caption: [Technika nepodméněného vstupu a výstupu _bufferu_])
- #underline[vstup] _(input)_ - procesor vyšle signál _RD_ (read)
- přikáže tím vstupnímu zařízení předat data do procesoru
- nijak se nekontroluje jestli je periférie připravená (očekává se, že je vždy připravená)
- #underline[výstup] _(output)_ - procesor vyšle signál _WR_ (write)
- výstupní zařízení data z procesoru převezme
- nijak se nekontroluje, jestli data periferní zařízení opravdu převzalo

caption: [Technika podmíněného vstupu a výstupu bez _bufferu_]
)
- #underline[vstup] _(input)_
- periferní zařízení připraví data na vyslání - pokud jsou data platná vyšle signál _STB (Strobe)_
- ten nastaví indikátor _(flag)_ $Q$ na 1 - $Q = 1$
- pokud je $Q = 1$ jsou data připravena pro předání do procesoru
- procesor si průběžně stav $Q$ kontroluje:
- vidí že $Q = 1$ $->$ data se přečtou procesorem vysláním signálu _RD (read)_ z procesoru
- ten zároveň nastaví $Q = 0$
- #underline[výstup] _(output)_
- procesor vyšle signál _WR (write)_ pro zápis dat do výstupního zařízení a data pošle
- zárověň tím nastaví $Q=1$
- periferní zařízení data z procesoru převezme a vyšle signál _ACK_ - data převzata
- nastaví tím $Q = 0$
- dá tím procesoru najevo, že data skutečně převzalo
- procesor může vyslat další data - periférie je připravena přijímat další data
- obrázky popisují #emph[jednosměrný korespondenční režim] (neúplný) - není zde _buffer_ uprostřed komunikace
- vysílač dat (ať už procesor nebo periférie) je povinen si data udržovat při celém průběhu komunikace - nemá _buffer_ (na obrázku jako registr), kam by je průběžně mohl zapisovat
= 28. Přenos dat použitím V/V brány s bufferem. Nakreslit obrázek komunikace jedním směrem a jak se liší komunikace druhým směrem. V jakých periferiích se používá.
- funguje na principu _input/output_ v technice bez _bufferu_ (minulá otázka) ale tentokrát ten _buffer_ má
- využíva _buffer_ (na obrázku registr) jako vyrovnávací paměť a klopný obvod _(flip-flop)_ jako semafor/indikátor
- jde o #emph[obousměrný korespondenční režim] (úplný) komunikace
- možnost vzájemného blokování _(interlock)_ - vysílač dat a přijímač dat testují stav indikátoru $Q$
- #underline[vstup] _(input)_
- $Q$ informuje procesoru připravenost dat ve vyrovnávací paměti _(bufferu)_
- pro periférii informuje $Q$
- zda procesor data již přečetl a je možno do _bufferu_ zaslat další data
- nebo data jěště přečtena nebyla a nemůže zaslat další data do _bufferu_
- #underline[výstup] _(output)_ - význam indikátoru $Q$ je pro procesor a periferii opačný než v _input_

= 29. Popiš DMA blok a nakresli schéma DMA řadič v architektuře dle von~Neumanna.
- DMA _(Direct Memory Access)_ blok / kontrolér / řadič
- umožňuje perifením zařízením vstupovat do hlavní paměti přímo
- přímý přesun dat mezi hlavní pamětí a periférii s minimální účasti procesoru
- bez _DMA_ bloku musí každý byte dat z periférie projít procesorem a až potom procesor může přistoupit do paměti
- procesor se samotného přesunu dat neučastní - pouze nastaví/naprogramuje _DMA blok_
- sběrnice musí být při přesunu uvolněna - může být maximálně jeden _budič_ sběrnice
- procesor přepne všechny budiče sběrnice do stavu vysoké impedance
- _DMA_ zajistí přesun - generuje sám adresy v paměti, kam se bude zapisovat/číst
- v _DMA_ bloku jsou tři registry sloužící pro styk se sběrnicí:
- _data register_ - obsahuje slovo, které má být přesunuto z periferie do paměti nebo naopak
- _address register_ - pro uchování adresy v hlavní paměti, na kterou bude slovo zapsáno nebo čteno
- _counter_ - počet slov, které mají být ještě přesunuty
- operace přístupu do paměti (z pohledu zápisu do paměti):
1. procesor naprogramuje blok _DMA_ - nastaví se registry _counter_ a _address_
+ blok _DMA_ spustí periferní zařízení a čeká až bude připraveno
+ periférie oznámí _DMA_ bloku, že je připravena - _DMA_ blok vyšle _DMA Request_
+ procesor dokončí strojovou instrukci a začne se věnovat _DMA Requestu_
- přímý přístup do paměti se vykonává synchronně při normální činnosti procesoru
- synchronně se přepíná přístup ke sběrnici a paměti mezi _DMA_ blokem a procesorem
- _DMA_ blok pracuje s pamětí ve fázi $Phi_1$ a procesor ve fázi $Phi_2$ interního hodin. signálu
+ DMA blok vyšle na adresovou sběrnici obsah svého _address registru_ a na datovou sběrnici obsah svého _data registru_
+ počka jeden paměťový cyklus $arrow$ inkrementuje _address register_, dekrementuje _counter_ (počet slov, které mají být ještě přesunuty)
+ testuje zda _counter_ $= 0$
- pokud ano - ukončí _DMA_ komunikaci a vrátí kontrolu nad sběrnici procesoru
- pokud ne - proces se opakuje od 5. kroku
- čtení funguje obdobně, jen opačným směrem

= 30. Jak adresujeme na úrovni strojového kódu - příklad.
- adresování dělíme na _přímé_ a _nepřímé_
- #underline[přímé adresování:]
- uvádíme konkrétní adresu v paměti
```c
int a = 12; // v jazyce C
int* a_ptr = &a;
printf("%p\n", a_ptr);
$> 0x7ffc58e5f904 // kontrétní adresa v paměti
```
```asm
mov eax, dword [0x7ffc58e5f904] ; v jazyce Assembly
```
- např. adresy globálních proměnných
- není běžné aby programátor adresoval data v paměti přímo
- #underline[nepřímé adresování:]
- adresujeme přes registry
```asm
mov rdx, 0x7ffc58e5f904 ; v registru se uloží adresa v paměti
mov eax, dword [rdx] ; do registru eax se uloží hodnota 12
```
- v 64-bit systémech s x86 instrukční sadou adresujeme pomocí:
- registrů (bázová adresa a index v poli, max. 2 registry)
- měřítka (počet bytů - `char = 1`, `short = 2`, `int = 4`, `long = 8`, a více),
- konstanty - většinou není potřebná
```asm
[bázový_registr + index_registr * měřítko + konstanta]
mov eax, dword [rdx + rcx * 4 + 0]
```
- `rdx` registr je zde bázovým registrem
- `rcx` registr představuje indexový registr
- číslo `4` je měřítkem - např. adresujeme pole ```c int array[N] = {0}```, protože ```c sizeof(int) = 4```
- vevnitř `[ ... ]` můžeme použít jenom operace sčítání $(+)$ a násobení $(*)$
#pagebreak()
= 31. Podmíněné a nepodmíněné skoky v strojovém kódu.
- skokové instrukce:
```asm
; tyto jsou nepodmíněné
jmp <target> ; nepodmíněný skok na <target>
call <target> ; zavolání podprogramu, skočí se <target>
ret ; skočí se zpět do nadprogramu
; jeho adresa je na stacku
; další jsou už podmíněné
; tyto testují registr rcx a jsou využivány pro cykly
loop <target> ; if(--ecx) goto <target>
loope <target> ; if(--ecx && zf) goto <target>
loopz <target> ; stejné jako loope
loopne <target> ; if(--ecx && !zf) goto <target>
loopnz <target> ; stejné jako loopne
jcxz <target> ; if(!rcx) goto <target>
; tyto rozhodují o vykonání skoku na základě jednoho bitu ve flags registru
; tím rozhodnou o vykonání skoku
; (testují jednotlivé bity ve stavovém (flags) registru procesoru)
jz / je <target> ; if equal = 1
jnz / jne <target> ; if equal = 0
js <target> ; if sign = 1
jns <target> ; if sign = 0
jc <target> ; if carry = 1
jnc <target> ; if carry = 0
jo <target> ; if overflow = 1
jno <target> ; if overflow = 0
; tyto řeší porovnavání čísel, taktéž hledí na bity ve flags registru
; (testují více flagů (bitů) ve flags registru)
ja / jnbe <target> ; if below = 0 && equal = 0
jb / jnae / jc <target> ; if below = 1 && equal = 0
jae / jnb / jnc <target> ; if below = 0 && equal = 1
jbe / jna <target> ; if below = 1 && equal = 1
jg / jnle <target> ; if less = 0 && equal = 0
jl / jnge <target> ; if less = 1 && equal = 0
jge / jnl <target> ; if less = 0 && equal = 1
jle / jng <target> ; if less = 1 && equal = 1
```
- skoky nepodmíněné, ```asm jmp, call, ret```, se vykonají vždy - _IP_ skočí na cílovou _(target)_ adresu
- skoky podmíněné se vykonají pouze, tehdy když jsou nastaveny správné flagy
- podmíněným skokovým instrukcím vždy předchází operace, které _setnou_ nebo _clearnou_ flagy ve _flags_ registru, který uchovává aktuální stav procesoru
- jakékoli aritmetické nebo logické operace ```asm sub, add, mul, and, or, xor ...```
- nejjednodušeji instrukcí ```asm cmp <cokoli>, <cokoli>```
- stejná jako instrukce ```asm sub```, ale neuloží výsledek
- pouze nastaví příznakové bity v registru ```asm flags```
- instrukce ```asm test <cokoliv>, <cokoliv>``` je stejná jako instrukce ```asm and```, ale neuloží výsledek

- v Assembly řešíme podmínky instrukcemi, které nastaví příznakové bity v registru ```asm flags```, a skokovými instrukcemi
- příznakové bity v 8-bit ```asm flags``` registru:
- ZF _(zero flag)_ - nastaví se pokud výsledek operace je nula
- SF _(sign flag)_ - nastaví se pokud výsledek operace je záporné číslo
- OF _(overflow flag)_ - nastaví pokud dojde ke znaménkovému přetečení _(signed overflow)_
- CF _(carry flag)_ - nastaví se pokud dojde k neznámenkovému přetečení _(unsigned overflow)_
- PF _(parity flag)_ - nastaví se pokud výsledek má sudý počet jedniček (např. `0110 1001`)
- AF _(auxiliary carry flag)_ - nastaví se pokud dojde ke `carry out` ve spodním `nibble`
- DF _(direction flag)_ - řídí směr `string` operací
- IF _(interrupt flag)_ - řídí povolení a zakázání přerušení
- instrukce, které nastaví příznakové bity:
- logické operace - ```asm and <d>, <s> or <d>, <s> xor <d>, <s> not <r>```
- aritmetic. operace - ```asm add <d>, <s> sub <d>, <s> inc <r> dec <r> mul <r> div <r>```
- komparační a testovací operace - ```asm cmp <d>, <s> test <d>, <s>```
- řídící operace - ```asm clc ; clear carry```, ```asm stc ; set carry``` - obdobně pro všechny příznak. bity
- řetězcové operace - ```asm movs, cmps, lods, stos```
- skokové instrukce: (viz minulá otázka bruv)
- na datových typech záleží v Assembly při všem - programátor je zodpovědný za vše a to i za správné určení datových typů
- Assembly neřeší co nějaká sekvence bitů v paměti znaměná/reprezentuje - ```c int, float, long, struct {int, float}, char```
- je mu to jedno - jsou to jenom bity v paměti bez žádného významu
- programátor jím dává význam - sami o sobě jsou jen "jedničky" a "nuly"
- syntakticky hledí Assembly na datové typy zadané programátorem u instrukcí s $d$ a $s$ parametry:
```asm INTRUCTION_NAME <d>, <s> ; d = destination, s = source```
- myšleno jako `destination` a `source` parametry - jsou jimi např.:
- přesuny - ```asm mov dest src ; velikost dest a src musí být stejná```
- násobení a dělení - ```asm div reg ; registry musí být stejné velikosti (rax / rcx)```
- komparace - ```asm cmp dest src ; musí být stejné velikosti```
- datové typy specifikují pouze velikost vyhrazené paměti
- žádné info o tom zda je to ```c int, char, char[], float```
- ```asm db / byte ; 1 byte, 8 bitů```
- ```asm dw / word ; 2 byty, 16 bitů```
- ```asm dd / dword ; 4 byty, 32 bitů```
- ```asm dq / qword ; 8 bytů, 64 bitů```
- zkrácené se používají při deklaraci proměnných v ```asm section .data```
- plné názvy se používají pro určení velikosti operandu v ```asm section .text```
```asm
section .data
some_var: db "Hello, World!", 0x00 ; some_var = "Hello, World!" + "\0"
section .text
mov eax, dword [rdx + rcx * 4] ; do eax se vloží dword toho co je na adrese
```

== Grafické karty (Nvidia) a CUDA
- CUDA je málé rozšíření jazyka C/C++ (také Python, Fortran)
- programové rozhraní umožňujicí využití _GPU_ vypočetní síly
- umožňuje využití výpočetní síly grafické karty:
- masivní paralelismus - stovky tisíc vláken vykonávají stejný kód
- všechna vlákna musí být na sobě nezávislé
- _GPU_ nezaručuje synchronní pořadí vykonání instrukcí
- grafické karty jsou navrženy tak, aby maximalizovali výpočetní výkon
- nejlépe by se mělo cyklům a podmíněným skokům zcela vyhnout
- nepodporuje _"out-of-order"_ vykonávání instrukcí jako _CPU_-čka od Intelu
- je optimalizováno pro sekvenční přístup do globální (hlavní / _"Device"_) paměti grafické karty
- přenosová rychlost až stovky GB/sekunda
- většina tranzistorů na kartě je výpočetních (je zde minimum řídicích a pomocných obvodů)
#figure(
image("cuda/image1.png", width: 50%),
caption: [Pohled na GPU architekturu z _"high level"_]
)
- na obrázku:
- grafikcé karty jsou rozdělené do _multiprocesorů_
- je to "pole" procesorů, které pracují spolu - vykonávají stejné instrukce na jiných datech _(SIMD)_
- každý _multiprocesor_ může vykonávat jiný kód _(MIMD)_
- každá grafická karta obsahuje různý počet _multiprocesorů_
- _Device Memory_ je paměť sdílená všemi _multiprocesory_
- skládá se z _Global Memory_, _Texture Memory_ a _Constant Memory_
- každý multiprocesor obsahuje svůj _Shared Memory_, jednotlivé procesory a vyrovnávací paměti
- _Shared Memory_ je sdílená paměť mezi všemi procesory v jednom multiprocesoru
- každý procesor má navíc své vlastní registry
- každy multiprocesor má vyrovnávací paměti _(Cache Memory)_ pro rychlejší přístup k datům v globální _Device_ paměti
- _Constant Cache_ je pro rychlý přístup k datům v _Constant Memory_
- _Texture Cache_ je pro rychlý přístup k datům v _Texture Memory_

)
#figure(
image("cuda/image4.png", width: 80%),
caption: [Organizace paměti - grafická karta _("Device")_ v počítači]
)
- _"Device"_ je grafické karta a skládá se z:
- _DRAM_ paměti _(Globální paměť grafikcé karty_ neboli _"Device Memory")_
- _GPU_ multiprocesorů
- _"Host"_ je jakýkoli počítač s nainstalovanou grafickou kartou
- paměti od _"Host"_ a _"Device"_ jsou propojeny pouze sběrnicí - nejsou sdíléné
#pagebreak()
#figure(
image("cuda/image5.png", width: 60%),

)
- některé počítače mají společnou sdílenou paměť mezi _CPU_ a _GPU_
= 33. Princip programování CUDA - jak, kde, kdy se přesouvají data při výpočtu.
#figure(
image("cuda/image6.png", width: 65%),
caption: [Výpočetní proces na grafické kartě]
)
- výpočetní proces s _CUDA_ se skláda z několika kroků:
1. data se z hlavní operační paměti počítače ("Host Memory") přesunou do paměti grafické karty ("Device Memory")
- nakopírují se data z _"ramky"_ do globální paměti grafické karty
- data jsou přenášena přes sběrnici počítače - dnes obvykle přes _PCIe_ (_Peripheral Component Interconnent Express_ - standard pro vysokorychlostní seriové sběrnice)
2. procesor _CPU_ dá pokyn ke zpracování
- naorganizuje vlákna (konfiguruje mřížku) a poskytne kód (instrukce), který se má spustit
3. vlákna (procesory) v _GPU_ multiproceserech vykonají poskytnutý kód (instrukce)
- paralelně se spustí všechna nakonfigurovaná vlákna, která vykonají stejný kód (instrukce) na jiných datech - _SIMD (Single Instruction Multiple Data)_
4. přesunutí výsledných zpracovaných dat z globální paměti grafické karty ("Device Memory") zpět do hlavní paměti ("Host Memory")
#pagebreak()
= 34. Jaké je C/C++ rozšíření CUDA a jak to využije programátor. Jak si programátor organizuje výpočet. K čemu je mřížka. Nákres dobrovolný.
- CUDA přínáší rozšíření jazyka C/C++, které umožňuje využít výpočetní výkon grafických karet vyráběných společností Nvidia
- jsou jimi _kernely_, modifikátory funkcí a proměnných, datové typy a struktury, předdefinované globální proměnné, API funkce s předponou `cuda`
- _kernel_ je funkce napsaná pro spuštění v jednotlivých jádrech grafické karty:
- klasicky napíšeme funkci v C++ a označíme ji modifikátorem ```c __global__``` (před/nad signatúru funkce)
- voláme je z _CPU_-čka ("Host") následujicí syntakcí:
```c functionName<<<gridDimensions, blockDimensions>>>(parameters...) ```
- do trojtých _"chevrons"_ ```<<< >>>``` zadáváme konfiguraci mřížky a to:
- velikost (dimenze) mřížky - jejím datovým typ je ```c dim3```
- velikost (dimenze) bloků v mřížce - jejím datovým typ je také ```c dim3```
- mřížka je od toho aby se _GPU_-čku při spuštění _kernelu_ nařídilo, jaký májí data _"tvar"_
- _RGBA_ obrázek o velikosti `1200x800` nakonfigurujeme do mřížky `1200x800x4`, kde čísla odpovídají počtům vláken na danou dimenzi
- při spuštění se ještě musí hledět na to, jak tyto vlákna přerozdělíme do bloků stejných rozměrů, tak aby se vešel každý pixel obrázku do finální mřížky
- mřížka může dále představovat tvar tenzorů, matic, vektorů apod.
- modifikátory funkcí - píšeme před signatúrou funkcí:
- ```c __host__``` - značí, že tuto funkci může spustit/zavolat pouze _CPU_-čko ("Host")
- ```c __device__``` - značí, že tuto funkci může spustit/zavolat pouze _GPU_-čko ("Device")
- ```c __global__``` - modifikátor pro tzv. _kernely_ - funkce spouštějicí se na _GPU_ multiprocesorech ("Device") a jsou zavolány _CPU_-čkem ("Host")
- modifikátory proměnných - píšeme před datovým typem proměnné:
- ```c __device__``` - deklaruje proměnnou, která bude sídlit v "Device" paměti po celou dobu běhu programu
- ```c __constant__``` - stejný jako `__device__` ale není možné ji přepsat - je _"read-only"_
- ```c __shared__``` - proměnná sídlí v "Shared Memory" jednoho bloku - je přístupná pouze pro vlákna v tomto bloku, nikým jiným
- `__managed__` - je přístupná jak z "Host" tak i z "Device" a je spravována tzv. "Unified Memory" systémem - CUDA spravuje přesun dat automaticky
- datové typy a struktury:
- všechny běžné datová typy v C/C++:
```cpp
char, uchar // typedef unsigned char uchar
int, uint // typedef unsigned int uint
short, ushort // typedef unsigned short ushort
long, ulong // typedef unsigned long ulong
float, double
```
- používají se struktury se stejnými jmény jako datové typy s číselnou příponou (1 až 4)
- značí kolik je tohoto datového typu vně struktury - přistupuje se k nim pomocí přístupových operátoru (```c . ->```) a jmén položek ```c .x, .y, .z, .w``` (klasická C syntaxe)
- ```cpp int3, uchar3, float3, uint3, ..., dim3 = uint3```
```cpp
int3 some_variable(12, 34, 56); // int3 some_variable = { .x=12, .y=34, .z=56 };
some_variable.x = 61; // int3 some_variable = { .x=61, .y=34, .z=56 };
```
- `dim3` je datovým typem mřížky a bloku zadávané do trojtých _"chevrons"_ při volání _kernelu_
- `cudaError_t` je datový typ pro udržení _error code_ (návratové hodnoty CUDA API funkcí)
- je důležitý při ladění kódu -- lze ho předat do `cudaGetErrorString(...)` funkce, která vrátí zprávu o tom, kde nastala chyba (co se stalo)
- předdefinované globální proměnné:
- slouží k zjištění přesného _ID_ (polohy, adresy) každého vlákna ve spuštěném _kernelu_
- ```c dim3 gridDim``` - udává dimenze trojrozměrné mřížky
- ```c dim3 blockDim``` - udává jak velký je blok v mřížce, opět je trojrozměrný
- ```c uint3 blockIdx``` - udává pozici bloku v mřížce, ve kterém se vlákno zrovna nachází
- ```c uint3 threadIdx``` - udává třídimenzionální pozici vlákna v bloku, ve kterém se nachází
- ```c int warpSize``` - záleží na architekruře grafické karty, udává kolik je vláken na jednom "Warp"
- není pro výpočet důležitý - je užitečný pro optimalizaci výpočtu pro určité architektrury grafických karet
- různé flagy/makra zadávané do `cuda` funkcí jako: ```c cudaMemcpyHostToDevice, cudaMemcpyDeviceToHost, cudaMemcpyDeviceToDevice, ...```
#figure(
caption: [Způsob adresování jednotlivých vláken ve dvou-dimenzionální mřížce],
image("cuda/image7.png", width: 60%)
)
```cpp
uint3 pos = {
blockIdx.x * blockDim.x + threadIdx.x,
blockIdx.y * blockDim.y + threadIdx.y,
blockIdx.z * blockDim.z + threadIdx.z
}; // uint3 pos ... představuje přesnou pozici jednoho vlákna v celé mřížce
```
- API funkce s předponou `cuda`: (je jich stovky, tady jen pár z nich)
```cpp
cudaError_t cudaDeviceReset(void);
cudaError_t cudaDeviceSynchronize(void);
cudaError_t cudaGetLastError(void);
const char* cudaGetErrorString(cudaError_t error);
cudaError_t cudaMalloc(void** devPtr, size_t size);
cudaError_t cudaMallocManaged(void** devPtr, size_t size, unsigned int flags);
cudaError_t cudaFree(void* devPtr);
cudaError_t cudaMemcpy(void* dst, const void* src, size_t count, cudaMemcpyKind k);
```
#pagebreak()
= 35. Čemu by se měl programátor vyhnout a jak CUDA funguje.
- fungování CUDA je popsáno v předchozích otázkách
- měl by se minimalizovat přesun dat mezi _"Host"_ a _"Device"_ paměťmi
- přes API funkci ```c cudaMemcpy(...)```, ideálně přesouvat data jen dvakrát - před výpočtem a po dokončení výpočtu
- používat _GPU_ pouze pro výpočetně náročné úlohy:
- image-processing (grafické editory)
- signal-processing (DAW - Digital Audio Workspace)
- v odvětví Machine-Learning - maticové a tenzorové operace
- ale ne všechny úlohy jsou vhodné počítat přes grafickou kartu
- pro intensivní přesuny mezi paměťmi využít _"pipelining"_ a _"prefetching"_
- přes API volání funkce ```c cudaMemPrefetchAsync(...)``` - asynchronně začne přesun dat za současného běhu hlavního programu
- data by se měla zorganizovat tak, aby se k nim mohlo přistupovat sekvenčně/sériově
- _GPU_ multiprocesory jsou optimalizováný na sekvenční přístup do svých _"Shared Memory"_
- např. při násobení matic $A dot B = C$ bychom měli matici $B$ před výpočtem transponovat
- zredukovat co nejvíce počet _"divergentních"_ vláken
- nejlépe, aby všechny vlákna vykonávali stejný sekvenční kód
- optimálně nakonfigurovat velikost mřížky (Grid) a bloků (Block) v mřížce
- pomáhá znalost architektury pracující grafické karty

- *SISD architektury* _(Single-Instruction Single-Data)_
- na jednu instrukci připadají jedny data
- jde o typické jednoprocesorové architektury
- mohou sice zpracovávat více instrukcí zároveň pomocí _"pipelining"_
- to však neznamená, že provádí kód paralelně
- jen zpracovávají několik instrukcí zároveň pomocí sekvenčního obvodu
- *SIMD architektury* _(Single-Instruction Multiple-Data)_
- na jednu instrukci připadá více dat
- příkladem mohou být různé vektorové a maticové operace
- násobení vektorů a matic, sčítání vektorů a matic, konvoluce matic, ...
- tyto architektury mají jednu řídicí jednotku a několik výpočetních jednotek
- výpočetní jednotky v jednu danou chvíli provádí stejnou instrukci na jiných datech
- jde tedy hlavně o vektorové procesory (specializované pro operace na vektorech) a procesorová pole (matice _elementárních_ procesorů - PE - Processing Element)
- jsou jimi např.:
- procesory s rozšířenou instrukční sadou
- MMX - _Multi-Media Extension_
- SSE - _Streaming SIMD Extension_
- 3DNow!
- AVX - _Advanced Vector Extension_
- AMX - _Advanced Matrix Extension_
- VNNI - _Virtual Neural Network Instructions_

- jedny data jsou postupně zpracovány více instrukcemi
- typickým zástupcem jsou systolická pole
- je to homogenní síť úzce spojených _DPU_-ček _("Data Processing Units")_ neboli uzlů
- z latinského _systola_ - kontrakce srdce - krev jako data, kontrakce jako více instrukcí
- použítí:
- obvody implementující třídicí algoritmy, Hornerovo schéma pro vyčíslení polynomu, násobení matic Cannonovym algoritmem apod.
- *MIMD architektury* _(Multiple-Instruction Multiple-Data)_
- systémy schopné provádět různé instrukce nad různými daty
- typickými zástupcemi jsou multiprocesory (na GPU) a multipočítače
- samostatné jednotky propojené komunikační sítí
- v praxi se nepíše kód pro každý procesor zvlášť
- všude běží stejný kód - podle ID procesu se zpracovávají různé větve kódu
- mluví se spíš o SPMD _(Single-Program Multiple-Data)_

*Architektury se sdílenou pamětí* _(ANO Sdílený adresový prostor, NE Distribuovaná paměť)_
- obsahují fyzicky sdílenou paměť (společná paměť i virtualní adresový prostor)
- všechny procesory, výpočetní jednotky, do ní mají stejně rychlý přístup
- jde o UMA _(Unified Memory Access)_ architektury
- stejná adresa na různých procesorech odkazuje na stejnou paměťovou buňku ve fyzické paměti
- je prostředkem komunikace mezi procesory
- tvoří úzké místo _(bottleneck)_ - omezuje se počet procesorů (do 100)
- jednotlivé procesory mají také svou lokální paměť _Cache_
- mnohem rychlejší - není přístupná jiným procesorům - to už není _UMA_ ale _NUMA (Non-UMA)_
- typický příklad je SMP _(Symmetric Multiprocessing)_
- grafické karty mívají několik multiprocesorů, každý se svou "Shared Memory" (viz CUDA)
- standardem pro vývoj je _OpenMP (Open Multi-Processing)_ API pro C, C++ a Fortran
*Architektury s distribuovanou pamětí* _(NE Sdílený adresový prostor, ANO Distribuovaná paměť)_
- nemají společnou paměť ani virtuální adresový prostor
- adresa do paměti v procesorech neodkazuje na stejnou fyzickou paměťovou buňku
- procesory komunikují spolu zasíláním zpráv přes komunikační síť
- náročnější z pohledu programátora
- odstranění společné paměti umožňuje vytvářet systémy s tisíci procesory
- standardem pro vývoj je _MPI (Message Passing Interface)_ API
*Architektury se sdíleně-distribuovanou pamětí* _(ANO Sdílený adresový prostor, ANO Distribuovaná paměť)_
- jde o architektury s distribuovanou pamětí s podporou sdíleného adresového prostoru
- jde o NUMA _(Non-Unified Memory Access)_
#pagebreak()
*Porovnání systému se sdíleným a nesdíleným adresovým prostorem*
- programování postavené na principu zasílání zpráv je náročnější
- posílání zpráv lze emulovat na systémech se sdílenou pamětí
- programy napsané se standardem _MPI_ (Arch. s dist. pam.) běží na SMP (Arch. se sdíl. pam.)
- programy napsané stadardem _OpenMP_ (Arch. se sdíl. pam.) neběží na systémech s dist. pamětí
*SMP (Symmetric Multiprocessing)* - multiprocesory se sdílenou pamětí
- stovky procesoru se skrytou pamětí (Cache paměti)
- mají jednu centrální sdílenou paměť - může mít několik bank
- je nutná sychronizace přístupu do této paměti
- škálovatelnost je limitována propustnosti paměťového rozhraní (Memory Interface)
- propojavací sítě:
#set enum(numbering: "a)")
+ centrální sběrnice _(bus based)_ - desítky okolo jedné sběrnice
+ křížový _(crossbar)_ přepínač - přepínání procesorů mezi více bank paměti
+ nepřímá vícestupňová síť _(multistage interconnection network)_ - levnější a chudší _crossbar_

= 38. Vysvětlit Amdahlův zákon a jak bychom se podle něj rozhodovali.
- u paralelizace je problém růstu výkonnosti jako celku
- navýšením výpočetní síly, by měl (v ideálním světě) růst výkon o stejný faktor
- objevují se zde však ztráty výkonu:
- při komunikaci - pomalé sběrnice, nutná koordinace (jeden po druhém) apod.
- kvůli nerovnoměrné či neoptimální vytížení procesorů - některé procesory pracují naplno, jiné se jen částečné zapojí do zpracování úlohy
- kvůli neznalosti vhodných algoritmů - vyberem neoptimální řešení pro řešení problému
- zrychlení jsou trojího typu:
#set enum(numbering: "1.")
+ zpomalení - velmi často se systém zpomalí
+ lineární - ideální růst výkonu
+ superlineární - nad-lineární růst výkonu (vzácně)
- čistě paralelních úloh je velmi málo:
- ve většině případů je kombinováno se sériovým zpracováním - program není paralelně zpracován po celou dobu jeho běhu, většina segmentů je zpracována sériově
- paralelizace je proto jenom částečná
- zrychlení výkonu lze odvodit z Amdahlova zákonu:
$ S_z = 1/( (1 - f_p) + f_p/N) #text(" nebo ") S_z = t/( t f_s + t f_p/N ) #text[kde platí] f_s + f_p = 1 $

= 认识 cargo
cargo 是 Rust 的包管理工具，并且是所有语言中最好用的包管理工具之一。cargo 提供了一系列的工具，从项目的建立、构建到测试、运行直至部署，为 Rust 项目的管理提供尽可能完整的手段。
= 创建一个“hello_world”项目
```sh
cargo new hello_world
```
Rust 项目名的多个单词间可以用“\_”或“-”分隔，例如：“hello_world”、“hello-world”，个人喜欢用“\_”分隔。Rust 项目分为 2 种，Binary 项目（默认）和 Library 项目，Binary 项目是可执行的，Library 项目是不可执行的。
示例：
```sh
cargo new --bin hello_world
carog new --lib hello_world
```
= 运行项目（当前目录位于 Cargo.toml 所在的目录中）
代码在对应项目的 `main()` 中。
```sh
cargo run # 以 Debug 模式编译和运行项目
cargo run --release # 以 Release 模式编译和运行项目
cargo build # 以 Debug 模式编译项目
cargo build --release # 以 Release 模式编译项目
```
= 快速验证代码能否通过编译
```sh
cargo check
```
= Cargo.toml 和 Cargo.lock
- `Cargo.toml` 是 `cargo` 的项目描述文件，存储着项目的所有元配置信息。
- `Cargo.lock` 是 `cargo` 根据 `Cargo.toml` 生成的项目详细依赖清单，不需要修改这个文件。
= 覆盖默认的镜像地址
在`$HOME/.cargo/config.toml`中添加以下内容：
```toml
[source.crates-io]
replace-with = 'ustc'
[source.ustc]
registry = "git://mirrors.ustc.edu.cn/crates.io-index"
```

A showcase of the [compile-typst-action](https://github.com/ammar-ahmed22/compile-typst-action) GitHub Action.
## What does it do?
Inside the `src` directory, there are 2 Typst documents, `calculus.typ` and `quadratic.typ`. On push to the main branch, the GitHub Action compiles them with [compile-typst-action](https://github.com/ammar-ahmed22/compile-typst-action) and commits the generated/updated PDF files. |

https://github.com/niuiic/typst-preview.nvim | https://raw.githubusercontent.com/niuiic/typst-preview.nvim/main/README.md | markdown | MIT License | # typst-preview.nvim
Neovim plugin to preview typst document.
[More neovim plugins](https://github.com/niuiic/awesome-neovim-plugins)
## Usage
1. Setup `typst-lsp`. (see example [here](https://github.com/niuiic/modern-neovim-configuration/blob/main/lua/lsp/typst_lsp.lua))
2. Call `require("typst-preview").preview()`.
<img src="https://github.com/niuiic/assets/blob/main/typst-preview.nvim/usage.gif" />
## How it works
1. Generate pdf files by `typst compile`.
2. Respond to subsequent file changes with `typst-lsp`.
3. Redirect these pdf files to a fixed path when you switch buffer.
4. Preview this pdf by a pdf viewer with the ability to respond to the file changes.
## Dependencies
- [typst](https://github.com/typst/typst) (typst compile command)
- [typst-lsp](https://github.com/nvarner/typst-lsp)
- [niuiic/core.nvim](https://github.com/niuiic/core.nvim)
- pdf viewer (recommend okular)
## Config
Default configuration here.
```lua
{
-- file opened by pdf viewer
output_file = function()
local core = require("core")
return core.file.root_path() .. "/output.pdf"
end,
-- how to redirect output files
redirect_output = function(original_file, output_file)
vim.cmd(string.format("silent !ln -s %s %s", original_file, output_file))
end,
-- how to preview the pdf file
preview = function(output_file)
local core = require("core")
core.job.spawn("mimeopen", {
output_file,
}, {}, function() end, function() end, function() end)
end,
-- whether to clean all pdf files on VimLeave
clean_temp_pdf = true,
}
```
## Notice
Shell commands `ln` and `mimeopen` are used by default. You may need alternatives if they don't exist.
The first time you execute `mimeopen` command, it requires you to set the default application, please run the command manually first, complete the settings before using the plugin.
It is recommended to enable this plugin as soon as reading a typst file, or temp pdf files cannot be cleaned completely.
## Compare to other tools
[typst-live](https://github.com/ItsEthra/typst-live) is awesome. However, severe flickering occurs when the file is updated. This is the limitation of the browser. In addition, it cannot switch files.
[chomosuke/typst-preview.nvim](https://github.com/chomosuke/typst-preview.nvim) supports cross jumping between code and preview, but does not support file switching yet. It should be noted that [typst-preview](https://github.com/Enter-tainer/typst-preview) used by this plugin implements the rendering logic itself instead of using official tools.

There are more half #strike[the] #underline[a] million fast food workers in California and many of them are#underline[n't] teenagers working in a#underline[n] after-school job. There are #underline[adults] , looking #underline[to keep a roof] over their heads, and food on their tables. And just this week, many of them just got 25% pay #strike[bomb] #underline[*bump*]. But not everyone is ready to order a happy meal after hearing this news. Many of these chain restaurants #strike[do not own] #underline[they're not owned] by the #underline[larger corporation,] they are owned by #underline[*franchisees*]. So they are more like small businesses, and #underline[these franchise store] owners, they are worried that the #strike[increasing] #underline[increase in] pay would make it too expensive to run their business, meaning they will have to *lay some people off* or stop plans to open new stores or even close some of their existing stores. But some researchers are questioning those fear around pay increases. They *state* over the past decade, California doubled its minimal #underline[*wage*], ending up at the current 16 dollars per hour. And during that time, the data shows that the #strike[increasing] #underline[increase in] pay did not lead to a lot of #strike[layout] #underline[*layoffs*] or #strike[slow down] #underline[a *slowdown*] in the pace of hiring. However, companies like Jack in the Box Starbucks, McDonald's and Chipotle say, they're going to raise prices in the State that already one of the most expensive places to live in the country.

大家好，让我们在这美好的星期二里精神饱满地开始一天，向所有辛勤工作、传授知识、激励我们的老师们致以崇高的敬意。所以一定要跟你的老师握手、击掌、拳头碰一下，让他们知道“我看到你了”。我是科伊，这里是CNN10，最精彩的10分钟新闻。振作起来吧！
首先，我们来到了加利福尼亚，那里的许多快餐工人刚刚获得了加薪。这是因为周一生效的新法律要求所有快餐店至少支付员工每小时20美元的工资。加利福尼亚有超过50万的快餐工人，其中许多并不是青少年在课后打工。他们是成年人，努力维持家庭生计(有家住，有饭吃)。而就在这一周，许多人的工资刚刚涨了25%。但并非每个人都因这个消息而感到开心。许多连锁餐厅并非由大公司所有，而是由加盟店经营。因此，它们更像是小型企业，而这些加盟店的业主们担心工资增加会使经营成本过高，意味着他们可能不得不裁员、取消开设新店的计划，甚至关闭一些现有店铺。但一些研究人员质疑了关于工资增加的这些担忧。他们指出，在过去的十年里，加利福尼亚的最低工资翻了一番，最终达到了当前的每小时16美元。而在此期间，数据显示，工资增加并没有导致大量裁员或招聘速度放缓。然而，像杰克快餐、星巴克、麦当劳和Chipotle这样的公司表示，它们将在这个已经是全美生活成本最高的州提高价格。

好的，接下来我们带你到Baltimore的Patapsco河上，看看Francis Scott Key Bridge的残骸。你可能还记得，就在上周二清晨，一艘货船撞上了这座著名桥梁的桥墩，导致其倒塌。官员们表示，在倒塌时有六名夜班修补坑洞的工人死亡。<NAME>会给大家带来更多关于Baltimore市接下来的计划：
你可以看到我们已经能够非常近距离地接触Dali的残骸，我们开始真正意识到这项工作将会有多庞大。你们看到的是4000吨的钢铁和混凝土压在船头上。这将是整个行动中最复杂的部分，清理所有的残骸并将其从船上取下，以便他们开始清理工作。然后还有潜藏在水下的所有东西，那些我们看不见的部分，水中还有更多的金属、混凝土和碎片。这一点至关重要，因为他们必须确保这对于潜水员是安全的，他们的任务是重新进入水中并继续搜索，试图找回那些失踪者的尸体。但是当我们坐在这里，现在终于能够看到并接近它时，你真的能感受到手头工作的巨大。但是这里的所有官员都告诉我们，他们有信心能够完成这项任务。他们正在共同努力，拥有所有必要的技术，他们正在逐步进行，采取一种细致入微的方法，确保他们做对了，并最终可以重新开放港口，开始重建，这对Baltimore市来说是重要的象征。Baltimore市和Maryland州可以得到清理。这里的人们可以开始恢复正常生活。我是<NAME>，CNN报道。

Officials #strike[state] #underline[said], six workers #underline[working an overnight shift fixing *potholes*] #strike[on a night shift] died when the bridge collapsed. <NAME> #strike[will show us the future plan about] #underline[has more on what's next for the city of] Baltimore.
You're seeing we have been able to be #underline[extremely] up close the #strike[debris] #underline[wreckage] of Dali, #strike[we start] #underline[and we're starting] to #strike[realize how large this work will be] #underline[really get an appreciation and a sense of just how massive this job is going to be]. #strike[What you're seeing are] #underline[You're looking at ] 4,000 tons of steel and concrete #strike[pressed] #underline[that are sitting] on #strike[the head] #underline[top] of the #strike[ship] #underline[bow]. #strike[This will] #underline[That is going to] be the most complicated part of the #strike[work] #underline[operation], #strike[cleaning up] #underline[moving] all the debris and #strike[move them away from] #underline[*taking it off*] the ship to #strike[start the cleanup] #underline[begin the cleanup process].

== Wolf
Owooooo, sorry, just #strike[get in reintroduce ] #underline[getting reintroduced to] my inner wolf. That's a lot like what's happening in Colorado, where people vote#underline[d] to reintroduce wolves back to their state. That's the first time ever in the country's history that the state has voted on this kind of #underline[*ballot*] *initiative*.

Owooooo, sorry, just getting reintroduced to my inner wolf. That's a lot like what's happening in Colorado, where people voted to reintroduce wolves back to their state. That's the first time ever in the country's history that the state has voted on this kind of ballot initiative. But as <NAME> shows us, after the vote passed by a slim margin, some folks in the more rural parts of the state weren't exactly howling with joy.
Humans adapting with wolves is going to be the biggest obstacle we're going to be dealing with.

==== 参考翻译
哦呜~~抱歉，刚刚释放了一下我的内心狼。这有点像科罗拉多正在发生的事情，那里的人们投票决定重新引入狼到他们的州。这是该国历史上州首次就这类选票倡议进行投票。但正如<NAME>ov向我们展示的，投票结果勉强通过后，该州更农村地区的一些人并没有欢呼雀跃。
人类适应与狼共存将是我们要面对的最大障碍。大约80年前，狼在科罗拉多几乎被根除，现在它们正式回归这个州，得益于美国历史上首次由选民强制重新引入濒危狼种的投票倡议。这些狼是从俄勒冈州捕获的，去年12月被释放到科罗拉多的荒野中。
“你饿了。我从未想过我能这么接近一只狼。”
“她是一位非常特别的大使。”
凯利·墨菲（<NAME>）是科罗拉多狼与野生动物中心的动物护理主管，她是帮助狼重新回到该州的倡导者之一。
“显然，这不是我们在野外会有的互动。”
“如果你在野外看到一只狼，我们的建议是拍照并认为自己很幸运，因为这可能再也不会发生了。”
曾经有大约200万只灰狼在北美自由地漫游。但当欧洲移民到来时，他们把他们的古老神话和对狼的仇恨带到了这里。到了20世纪40年代，狼几乎被消灭殆尽。
“有很多关于狼的神话和误解。有时候很难理解它们并不完全正确。”
作为食物链顶端的顶级捕食者，它们帮助控制某些动物群体的数量，从而帮助植物、树木和其他野生动物茁壮成长。
“它们对于维护我们生态系统的平衡至关重要，这意味着对牧场主来说，这是一个更具生产力的景观。”
“那狼对这头特定的牛做了什么？”
“所以它用嘴咬住她的喉咙，然后用后腿咬住她。它已经好了很多。”
唐·吉特尔森（<NAME>）在投票倡议之前就在科罗拉多北部的牧场上抵御狼的侵入。
“我们这里已经有狼好几年了。”
它们是从邻近的怀俄明州来的，怀俄明州在90年代重新引入了狼。
“对我来说，这是我的家。对它们来说，这也是它们的家。它们不会就这样离开。”
“看到这里的雪上有这些痕迹吗？”
“那是狼的踪迹吗？”
“这是它们上次经过的痕迹。”
在科罗拉多，狼重新引入的提案几乎只在像丹佛和博尔德这样的城市地区获得了大部分赞成票。
“人们对狼有很强烈的意见。无论他们站在哪一边。”
但在这个农村的科罗拉多州，他们的立场是明确的。州政府为农场主因牲畜被攻击而进行补偿。但由于在科罗拉多州狩猎狼是非法的，唐必须变着法子使用驴子（“它们咬得很狠。”）、长角牛和发射空弹。至于围栏？
“在这么大的地方放一个围栏？”
“是的，一尺高的铁丝网围栏来阻止狼。我这里有驼鹿、白尾鹿、麋鹿和羚羊，它们在这片地方来回迁徙。我绝对不会阻止它们这么做。”
“你关心这片土地。”
“所以你不能仅仅针对一个物种进行管理。”
我们不想让农场主自己应对这些问题。有许多组织和非政府组织愿意帮助实施这些非致命性的措施，因为归根结底，农场主和狼的倡导者都想要清洁的空气、清洁的空间和健康的环境和生态系统。我认为狼是实现这一目标的关键因素之一。

= 1. HDR
HDR（高动态范围）指的是游戏引擎处理非常明亮的光或颜色的能力。Bevy 的渲染器内部是 HDR 的，这意味着你可以拥有颜色超过 1.0 的对象、非常明亮的光源或明亮的自发光材料。
这与 HDR 显示输出不同，后者是指能够生成 HDR 图像并在具有 HDR 功能的现代显示器或电视上显示。Bevy 目前还不支持这一点。
内部 HDR 图像必须在显示到屏幕上之前转换为 SDR（标准动态范围）。这个过程称为色调映射。Bevy 支持不同的算法，可以产生不同的效果。选择哪种色调映射算法是一个艺术选择。
= 2. 相机 HDR 配置
每个相机都有一个切换开关，让你决定是否希望 Bevy 内部保留 HDR 数据，以便后续的渲染过程（如后处理效果）可以使用它。
```rs
commands.spawn((
Camera3dBundle {
camera: Camera {
hdr: true,
..default()
},
..default()
},
));
```
如果启用，Bevy 的中间纹理将采用 HDR 格式。着色器输出 HDR 值，Bevy 将存储它们，以便在后续渲染过程中使用。这允许你启用像 Bloom 这样的效果，这些效果利用 HDR 数据。色调映射将在 HDR 数据不再需要之后作为后期处理步骤进行。
如果禁用，着色器预计输出 0.0 到 1.0 范围内的标准 RGB 颜色。色调映射在着色器中进行。HDR 信息不会被保留。需要 HDR 数据的效果（如 Bloom）将无法工作。
默认情况下是禁用的，因为这对于不需要复杂图形的应用程序来说，性能更好且减少了显存使用。
= 3. 色调映射
色调映射是渲染过程中将像素颜色从引擎中的中间表示转换为最终显示在屏幕上的值的步骤。
这对于 HDR 应用程序非常重要，因为在这种情况下，图像可能包含非常亮的像素（超过 1.0），需要重新映射到可以显示的范围内。
Bevy 支持多种不同的色调映射算法。每种算法都会产生不同的效果，影响颜色和亮度。这可以是一个艺术选择。你可以决定哪种算法最适合你的游戏。Bevy 的默认算法是 TonyMcMapface，尽管名字有点搞笑，但它为各种图形风格提供了非常好的效果。
一些色调映射算法（包括默认的 TonyMcMapface）需要 tonemapping_luts cargo feature。默认情况下启用。如果你禁用了默认特性并且需要它，请确保重新启用它。 |
