However, I tried searching internet for images of resulting circle packs, and I could hardly find just a few. Those that I found had some unusual beauty in them. I suspect whole beauty of such circle packs is still not discovered.
I would like to know if somebody tried to generate circle packs corresponding to some known classes of planar graphs, like these:
or similar?

It's hard to find good implementations of circle packing. Even we had some, the software is slowly going out of date. At least, a theory is pinned down in some papers:
* [The convergence of circle packings to the Riemann mapping](http://projecteuclid.org/euclid.jdg/1214441375) that any graph has circle packings leads to a proof of the Riemann Mapping theorem
* [On the convergence of circle packings to the Riemann Map](http://www.cs.jhu.edu/~misha/Fall09/He96.pdf)
* [Approximation of Conformal Structures via Circle Packing](http://www.cs.jhu.edu/~misha/Fall09/Stephenson97.pdf)
* [Wikipedia](https://en.wikipedia.org/wiki/Circle_packing_theorem) has many interesting references as well. | If you read the very last item in the paper that you linked, you will see that the authors of that paper give a [link to software that computes circle packings](http://www.math.utk.edu/~kens/). |

Now, lambda syntax; to convert the anonymous class:
```
final FilenameFilter filter = new FilenameFilter() {
@Override
public boolean accept(File dir, String name) {
return false;
}
};
```
We start by replacing the anonymous class with an equivalent lambda for the single method `accept(File dir, String name)`:
```
final FilenameFilter filter = (File dir, String name) -> {
return false;
};
```
But we can do better, we don't need to define the types - the compiler can work those out:
```
final FilenameFilter filter = (dir, name) -> {
return false;
};
```
And we can do better still, as the method return a `boolean`; if we have a single statement that evaluates to a `boolean` we can skip the `return` and the braces:
```
final FilenameFilter filter = (dir, name) -> false;
```
This can be any statement, for example:
```
final FilenameFilter filter = (dir, name) -> !dir.isDirectory() && name.toLowerCase().endsWith(".txt");
```
However, the `File` API is **very** old, so don't use it. Use the [`nio API`](http://docs.oracle.com/javase/tutorial/essential/io/pathClass.html). This has been around since Java 7 in 2011 so there is really **no** excuse:
```
final Path p = Paths.get("/", "home", "text", "xyz.txt");
final DirectoryStream.Filter<Path> f = path -> false;
try (final DirectoryStream<Path> stream = Files.newDirectoryStream(p, f)) {
stream.forEach(System.out::println);
}
```
And in fact your example has a specific method built into `Files` that [takes a Glob](https://docs.oracle.com/javase/8/docs/api/java/nio/file/Files.html#newDirectoryStream-java.nio.file.Path-java.lang.String-):
```
final Path p = Paths.get("/", "home", "text", "xyz.txt");
try (final DirectoryStream<Path> stream = Files.newDirectoryStream(p, "*.txt")) {
stream.forEach(System.out::println);
}
```
Or, using the more modern [`Files.list`](https://docs.oracle.com/javase/8/docs/api/java/nio/file/Files.html#list-java.nio.file.Path-):
```
final Path p = Paths.get("/", "home", "text", "xyz.txt");
final PathMatcher filter = p.getFileSystem().getPathMatcher("glob:*.txt");
try (final Stream<Path> stream = Files.list(p)) {
stream.filter(filter::matches)
.forEach(System.out::println);
}
```
Here `filter::matches` is a method reference because the method `PathMatcher.matches` can be used to implement the functional interface `Predicate<Path>` as it takes a `Path` and returns a `boolean`.

] | You have two issues here. Firstly you're not using `click()` correctly. The first argument in your case is the additional data you want to include in the event, but that's not relevant to your use case. Instead it appears you're trying to create a delegated event handler, but you need to use `on()` for that.
Secondly, you need to traverse the DOM to find the parent `li` from the clicked element. `closest()` will achieve this for you.
```js
$("#sortable").on('click', "#editor_click_icon_edit", function(e) {
console.log($(this).closest('li').prop('id'));
});

//.editor-sortable-movable grabs the li
$(document).ready(function () {
$("#sortable > li").on("click",function(e) {

It indexes a large code base according to the atoms (tokens) of the language(s) of interest, and then uses that index to quickly execute structured queries stated in terms of language elememnts. It is a kind of super-grep, but it isn't fooled by comments or string literals, and it automatically ignores whitespace. This means you get a lot fewer false positive hits than you get with grep.
If you had an identifier "foo", the following query would find all mentions:
```
I=foo
```
For C and Java, you can constrain the types of identifier accesses to Use, Read, Write or Defines.
```
D=bar*
```
would find only *declarations* of identifiers which started with the letters "bar".
You can write more complex queries using sequences of language tokens:
```
'int' I=*baz* '['
```
for C, would find declarations of any variable name that contained the letters "baz" and apparantly declared an array.
You can see the hits in a GUI, and one-click navigate to a source code view of any hit.

] | **Potential Solution** I think at least a little hackery is required no matter how you optimize it - protractor doesn't give you this out of the box. However would a small helper function like this suit your needs? What else do you need to speed up sides `text` `input`s with `ng-model`s?
```
function setNgModelToString(element, value) {
return element.getAttribute('ng-model').then(function (ngModel) {
element.evaluate('$eval("' + ngModel + ' = \'' + value + '\'") && $digest()');
});
}
```
**Solution Example:**
```
describe('angularjs homepage', function() {
it('should have a title', function() {
browser.get('http://juliemr.github.io/protractor-demo/');
var inputString1 = '';
var inputString2 = '';
for (var i = 0; i < 1000; i++) {
inputString1 += '1';
inputString2 += '2';
}
/* Uncomment this to see it runs much much slower when you enter each key. */
//element(by.model('second')).sendKeys(inputString1);
setNgModelToString(element(by.model('second')), inputString2);
expect(element(by.model('second')).getAttribute('value')).toEqual(inputString2);
});
});
```
**Why does the solution work?**
You need to use `$eval` to wrap the assignment and not just assignment as `evaluate` does not evaluate side effects (a nested evaluation, though... heh). Assuming that's truthy in angular expressions then `$digest()` is called from the `&&`; this causes a digest to happen, which you need to update everything since you set a value from outside the digest cycle.
**Thoughts about the solution:**
The whole idea behind an E2E test is to "emulate" an end-user using your app. This arguably doesn't do that as well as sending the keys one-by-one, or copy-and-paste (since pasting into elements is a valid way of entering input; it's just hard to set up due to flash, etc., see below).
**Other Potential Solutions:**
* *Copy and Paste:* Create an element, enter text, copy it, paste the text sending Ctrl + V to the target element. This may require doing a bunch of fancy footwork, like using Flash (exposing the system clipboard is a security risk) and having "copy it" click an invisible flash player. See [`executeScript`](http://angular.github.io/protractor/#/api?view=webdriver.WebDriver.prototype.executeScript) to evaluate functions on the target so that you have access to variables like `window` if you need that.
* *Parallelizing your tests.* Read the official doc [here](https://github.com/angular/protractor/blob/master/docs/referenceConf.js) and search for "shard" and then "multiple". If you're mainly worried about the duration of your entire test collection and not individual tests, scaling out your browser count is probably the way to go. However there's a good chance you are TDD-ing or something, hence needing each test to run faster. | You can do following -
```
ExamPage.prototype.enterDetailsInputData = function (modifier) {

] | **Potential Solution** I think at least a little hackery is required no matter how you optimize it - protractor doesn't give you this out of the box. However would a small helper function like this suit your needs? What else do you need to speed up sides `text` `input`s with `ng-model`s?
```
function setNgModelToString(element, value) {
return element.getAttribute('ng-model').then(function (ngModel) {
element.evaluate('$eval("' + ngModel + ' = \'' + value + '\'") && $digest()');
});
}
```
**Solution Example:**
```
describe('angularjs homepage', function() {
it('should have a title', function() {
browser.get('http://juliemr.github.io/protractor-demo/');
var inputString1 = '';
var inputString2 = '';
for (var i = 0; i < 1000; i++) {
inputString1 += '1';
inputString2 += '2';
}
/* Uncomment this to see it runs much much slower when you enter each key. */
//element(by.model('second')).sendKeys(inputString1);
setNgModelToString(element(by.model('second')), inputString2);
expect(element(by.model('second')).getAttribute('value')).toEqual(inputString2);
});
});
```
**Why does the solution work?**
You need to use `$eval` to wrap the assignment and not just assignment as `evaluate` does not evaluate side effects (a nested evaluation, though... heh). Assuming that's truthy in angular expressions then `$digest()` is called from the `&&`; this causes a digest to happen, which you need to update everything since you set a value from outside the digest cycle.
**Thoughts about the solution:**
The whole idea behind an E2E test is to "emulate" an end-user using your app. This arguably doesn't do that as well as sending the keys one-by-one, or copy-and-paste (since pasting into elements is a valid way of entering input; it's just hard to set up due to flash, etc., see below).
**Other Potential Solutions:**
* *Copy and Paste:* Create an element, enter text, copy it, paste the text sending Ctrl + V to the target element. This may require doing a bunch of fancy footwork, like using Flash (exposing the system clipboard is a security risk) and having "copy it" click an invisible flash player. See [`executeScript`](http://angular.github.io/protractor/#/api?view=webdriver.WebDriver.prototype.executeScript) to evaluate functions on the target so that you have access to variables like `window` if you need that.
* *Parallelizing your tests.* Read the official doc [here](https://github.com/angular/protractor/blob/master/docs/referenceConf.js) and search for "shard" and then "multiple". If you're mainly worried about the duration of your entire test collection and not individual tests, scaling out your browser count is probably the way to go. However there's a good chance you are TDD-ing or something, hence needing each test to run faster. | If you really want to speed up the process of manipulating DOM in any way (including filling up data forms) one option to consider is to use: [`browser.executeScript`](http://angular.github.io/protractor/#/api?view=webdriver.WebDriver.prototype.executeScript) or [`browser.executeAsyncScript`](http://angular.github.io/protractor/#/api?view=webdriver.WebDriver.prototype.executeAsyncScript). In such a case the `webdriver` let the browser execute the script on its own -- the only overhead is to send the script body to the browser, so I do not think there may be anything faster.
From what I see, you identify DOM elements by `id`s so it should smoothly work with the approach I propose.
Here is a scaffold of it -- tested it and it works fine:
```
browser.get('someUrlToBeTested');
browser.waitForAngular();
browser.executeScript(function(param1, param2, param3){
// form doc: arguments may be a boolean, number, string, or webdriver.WebElement
// here all are strings: param1 = "someClass", param2 = "someId", param3 = "someModifier"
var el1 = document.getElementsByClassName(param1)[0];
var el2 = document.getElementById(param2);
el1.setAttribute('value', 'yoohoo ' + param3);
el2.setAttribute('value', 'hooyoo ' + param3);
// depending on your context it will probably
// be needed to manually digest the changes
window.angular.element(el1).scope().$apply();
},'someClass', 'someId', 'someModifier')
```
*small remark*: If you pass `webdriver.WebElement` as one of your argument it will be cast down to the corresponding `DOM element`. |

console.log('call is ', call);

] | I take your question to be, are the listed features sufficient to precisely and completely distinguish classical logic from all non-classical logics? There are certainly lots of other things one would need to specify in order for classical logic to qualify as a logic at all. And there are many other distinguishing features of classical logic not listed that follow from the ones that are listed.
The problem with giving a definitive answer to this question is that it is a matter of disagreement over exactly what constitutes a classical logic. Some use the term in a limited fashion to include only elementary first-order predicate logic. Others use it in a more extended way to include any logic that has the property that all theorems of elementary classical logic are theorems of that logic. These come apart in a number of ways, some of which are:
1. The standard semantics of classical logic is bivalent, which is to say it is the logic of pairs of opposite values, usually true/false, such that every proposition has one and only one value. But some accounts allow that multi-valued logics can be classical, as long as these logics are strictly extensions of bivalent classical logic and do not conflict with it.
2. Modal logics are commonly treated as non-classical in modern textbooks, but usually they extend classical logic and so would count as classical logics in the extended sense.
3. The identity relation is often treated as part of the logic, rather than as a predicate that can be interpreted as part of a theory. One speaks of first-order predicate logic *with* or *without* identity.
4. There are standard rules for handling variables, quantifiers and domains in classical logic. These can be extended in various ways, e.g. with plural quantification, branching quantifiers, typed variables, etc. Some of these extensions might be considered classical, but others, such as the ability in free logics to quantify over non-existent objects, are usually considered non-classical.
5. First order logic can be extended to second order and higher orders. Some logicians (famously Quine) do not consider these to qualify as logic at all.
The listed features do not stipulate bivalence, do not exclude non-truth-functional modal operators, do not specify any identity relationships, do not place any restrictions on quantification, and do not specify first-order, so they are obviously intended to characterise classical logic in an extended sense. | Short Answer

"While not entailed by the preceding conditions" means that 'there is more than these 5 conditions to describe classical logical study'. Five sentences would hardly be enough to describe classical logic.

What is classical logic? According to the [*Encyclopedia of Philosophy*](https://en.wikipedia.org/wiki/Encyclopedia_of_Philosophy) and it's entry 'Logic, Non-Classical':
>
> [C]lassical logic [is] the theory of validity concerning truth functions and first-order quantifiers likely to be found in introductory textbooks of formal logic at the end of the twentieth century.
>
>

One way to define what classic logic is is to define it as what non-classic logic is not. (See PhilSE: [In how many and which ways can a logic be non-classical? Are there systems for organizing them?](https://philosophy.stackexchange.com/questions/77449/in-how-many-and-which-ways-can-a-logic-be-non-classical-are-there-systems-for-o) for a list of systems and their characteristics.) This is why the principles are featured prominently in this article because what non-classic logic is about is deviation from some of these principles. For instance, [sequent calculus](https://en.wikipedia.org/wiki/Sequent_calculus) and its extensions such as display calculi, nested sequent systems, and labeled sequent systems are metalogical and go beyond classic-logic as [metalogical theory](https://en.wikipedia.org/wiki/Metalogic). But it's much more informative to describe some of the features of classic logic and some of their historical origin.
Is there more than the principles? Well as the WP article concedes, yes. In fact, of the three generally acknowledged [Laws of Thought](https://en.wikipedia.org/wiki/Law_of_thought), one is not mentioned in the list of principles above: the [Law of Identity](https://en.wikipedia.org/wiki/Law_of_identity). So, immediately, the moment discussion starts about classic logic, the Law of Identity is an important topic; the famous [philosopher of language](https://en.wikipedia.org/wiki/Philosophy_of_language), [John Searle](https://en.wikipedia.org/wiki/John_Searle), for instance, challenged the Law of Identity as a law arguing it is only a convention in his paper *Proper Names*. (See PhilSE: [On Searle's \_Proper Names\_ (1958)](https://philosophy.stackexchange.com/questions/77338/on-searles-proper-names-1958/77470#77470) for an explanation how he invokes the conventions of cryptography to challenge it.)
From Volume 5 of the *Encyclopedia of Philosophy*, the entry "Logic, Traditional" begins with this:
>
> In logic, as in other fields, whenever there have been spectacular changes and advances, the logic that was current in the preceding period has been described as "old" or "traditional"...In every case, the logic termed "old" or "traditional" has been essentially Aristotelian, but with a certain concentration on the central portion of the Aristotelian *corpus*, the theory of categorical syllogism... especially of the sixteenth to the nineteenth century.
>
>
>
In fact, WP's entry on the [History of Logic has a subsection on traditional logic](https://en.wikipedia.org/wiki/History_of_logic#Traditional_logic):
>
> Other works in the textbook tradition include [Isaac Watts's](https://en.wikipedia.org/wiki/Isaac_Watts) *Logick: Or, the Right Use of Reason* (1725), [Richard Whately's](https://en.wikipedia.org/wiki/Richard_Whately) *Logic* (1826), and [John Stuart Mill's](https://en.wikipedia.org/wiki/John_Stuart_Mill) *A System of Logic* (1843). Although the latter was one of the last great works in the tradition, Mill's view that the foundations of logic lie in introspection[87] influenced the view that logic is best understood as a branch of psychology, a view which dominated the next fifty years of its development, especially in Germany.[88]

So, besides missing the Law of Identity, here are some additional topics: [categorical syllogism](https://en.wikipedia.org/wiki/Syllogism), the [logic of propositions](https://en.wikipedia.org/wiki/Propositional_calculus), [equipollence](https://en.wikipedia.org/wiki/Equinumerosity), and [Euler's diagrams](https://en.wikipedia.org/wiki/Euler_diagram), as well as the [history of classical logic](https://en.wikipedia.org/wiki/Classical_logic#History) more generally to understand the context of their development and relations. In fact, two of the most important works are from three heavyweights of the [analytical tradition](https://en.wikipedia.org/wiki/Analytic_philosophy). According to that WP article:

Is there a way to make NuGet copy its content to the Modules folder? (and not to the root path)

] | I found that the best solution for this matter is the following:
Take the files that need to be loaded and put them on the content folder. This can be done simply:
```
<ItemGroup>
<Content Include=" {here go the needed files} " />
</ItemGroup>
```
The content folder just holds the files, but it **does not** copy them to the output folder on the client project. In order to copy them to the desired output, a .targets file can be used, just like the following:
```
<?xml version="1.0" encoding="utf-8" ?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<Target Name="CopyToOutput" AfterTargets="Build">
<ItemGroup>
<FilesToCopy Include="$(MSBuildThisFileDirectory)..\content\**\*.*"/>
</ItemGroup>
<Copy
SourceFiles="@(FilesToCopy)"
DestinationFiles="@(FilesToCopy->'$(OutDir)/%(RecursiveDir)%(FileName)%(Extension)')"/>
</Target>
</Project>
```
**Keep in mind that the targets file name and the ID of the NuGet have to be equal for the targets file to be added to the project.** | You should be able to use a target of `content/Modules`. Anything in the `content` directory is copied in to the `bin` directory on build.
If you were trying to use the special "convention based" folders, like `lib/net45`, those are directories that cause Visual Studio to automatically create an assembly reference when the package is installed. You shouldn't use those for regular content files.
See the [documentation](https://learn.microsoft.com/en-us/nuget/reference/nuspec#including-content-files) for more details. |

] | Work around is to temporary enable public access:
```
az storage account update --resource-group "$ResourceGroupName" --name "$Name" --default-action Allow
```
And after you are done with your operation you can turn it off again. | Communication between microsoft hosted agents and storage account behind firewall is always a troublesome one, even with the above work around of dynamically opening the storage firewall for that specific microsoft hosted agents IP address. This is mainly due to limitations on the storage account side.
**1. Each storage account supports up to 200 IP network rules.**
So we cannot add the entire IP ranges of hosted agents that spin up from any of your ADO orgs geographical region. If organization is hosted in West Europe, then hosted agents can come up from North and West Europe. So the no. of IP ranges that should be whitelisted will be more than 200.
Due to this, users go with the above work around of allowing the particular hosted agent IP address. however the following limitations will not make the above workaround fool proof. When the hosted agent spin up in the same region as your storage account, workaround does not work.
**2. Services deployed in the same region as the storage account use private Azure IP addresses for communication.**
**3. IP network rules have no effect on requests originating from the same Azure region as the storage account** |

Optionally match the following block:
* Match a forward slash `/`
* Either match a two digit number
* Or match a number between `100` and `119` (inclusive)
* Or match a number a number between `120` and `128` (inclusive)

] | You should break your tests up more, both for your sake with debugging and to mitigate issues with the protractor control flow. Changing your tests to the following works:
```
import { browser, element, by } from 'protractor';
describe('protractor-test-project App', () => {
it('goes to google', () => {
browser.waitForAngularEnabled(false);
browser.get('https://www.google.com');
expect(browser.getCurrentUrl()).toEqual('https://www.google.com/');
});
it('enters a search', () => {
const inputEl = element(by.id('lst-ib'));
browser.wait(() => inputEl.isPresent(), 10000, 'too long');
inputEl.sendKeys("protractor issue waitForAngularEnabled");
expect(inputEl.getAttribute('value')).toEqual('protractor issue waitForAngularEnabled');
});
it('returns to angular page', () => {
browser.get('/');
browser.waitForAngularEnabled(true);
const titleElement = element(by.id("title"));
expect(titleElement.isPresent());
});
});
```
Can't say for sure why the control flow wouldn't be handling this properly, but this seems to be caused by having two `waitForAngularEnabled` in the same spec (also might be because of navigating twice). If you disable your second one (where you re-enable it), your test works.
So you can either use my solution above which breaks them out into multiple steps, or you can nest the call under `browser.get` which also seems to work i.e.
```
browser.get('/').then(() => {
browser.waitForAngularEnabled(true);
});
```
Again, not sure why exactly that would happen. The control flow *should* be synchronizing these steps so using `.then()` shouldnt be necessary... but apparently it is. Breaking tests out into multiple `it` blocks also helps protractor synchronize things in the proper order | Using `waitForAngularEnabled` multiple times in the same test can be done, but requires a non-obvious addition of `browser.get`. Intuitively, most people think that setting `waitForAngularEnabled(true)` waits for protractor to pick up Angular tasks again but this returns a promise. Most people use it in a way where they can disable it on non-Angular pages and re-enable it on Angular pages, aka in a synchronous way. To solve this, you can use the following:
```
// do things on your Angular application
waitForAngularEnabled(false)
// do things on non-angular page
waitForAngularEnabled(true)
browser.get('/home') // this is a page from your Angular application
```
The `browser.get` function blocks until the Angular page is loaded. |

1,744,970 | I'm using Windows 11 Insider Preview 10.0.22622.290 on my Lenovo [Flex 5i 15](https://www.lenovo.com/il/en/laptops/ideapad/ideapad-flex-series/IdeaPad-Flex-5-15ITL-05/p/88IPF501454?orgRef=https%253A%252F%252Fwww.google.com%252F).
The pen I'm using is the Lenovo [Active Pen 2](https://support.lenovo.com/us/en/solutions/acc100370). It has 2 side buttons and up until about two months ago, the upper button, when used, would function as '**[barrel button](https://support.lenovo.com/us/en/solutions/ht508862-how-to-use-the-buttons-from-your-lenovo-digital-pen)**' which would function as right click on most things.
In some apps such as OneNote (and Microsoft Whiteboard) it would activate *lasso select* and this is the important part for me as I use OneNote as my notebook app for university.
### What I think happend:
It seems to me as this functionality was broken by some Windows update not long ago but I can't figure out which one and sadly I cannot roll back windows far enough to find out since my laptop had a bios update and doesn't want me to roll back windows to before it.
### What I've tried:
In the Lenovo pen software the settings the button is mapped as 'barrel button' by default and I double checked it still is.
I would be good to mention that I have **another Active Pen 2** (for emergencies) and that the problem happens on both of them and that every other part of the pen still works the same:
* The bluetooth button on the top of the pen.
* The lower side button still functions as eraser.
* The pen itself works.
I tried disabling its software and tried to update it but nothing changed.
Tried to mp the barrel button function to the lower side button and nothing.
It almost feels like the '*barrel button*' was removed from Windows.
Setting the button to function as right click does not solve the problem since it turns to a mouse cursor when doing so and does not work as lasso select in onenote
It seems like pressing the button just registers as a normal click.

15,396,895 | Quite a strange problem I have here, I am trying to run the DXUT DirectX 10/11 tutorials from DirectX sample browser.

] | I literally just spent all day trying to fix this exact same problem. Here is the solution which should hopefully fix yours too...
I managed to find this article explaining that a recent update, *(26th February 2013 to be exact)*, caused the older version to mess up:
<http://blogs.msdn.com/b/chuckw/archive/2013/02/26/directx-11-1-and-windows-7-update.aspx>
That explains why it was working fine a few weeks ago, and now it just suddenly stopped working I guess!
Following their advice, **I downloaded a trial version of Visual Studio 2012**, and after an hour and a half of installation time, and a system restart, you should have all the new DirectX SDK files that you need.
NOTE: You don't even have to use Visual Studio 2012. The new files should fix your issues for Visual Studio 2010 and older versions I presume!
(Before doing this **I also installed all the latest drivers**, but I don't think that did anything to help, but it's worth upgrading drivers whenever you can, as that has fixed a similar issue I had before).
Hope this helps!!! :) | Somewhere in your code you probably have something along the line of this
```
#if defined(DEBUG) || defined(_DEBUG)
createDeviceFlags |= D3D10_CREATE_DEVICE_DEBUG;
#endif
```
If you do take a look at the `D3D10_CREATE_DEVICE_DEBUG;` on the [msdn](http://msdn.microsoft.com/en-us/library/windows/desktop/bb204909%28v=vs.85%29.aspx) you will see this
>
> To use this flag, you must have D3D11\_1SDKLayers.dll installed;
> otherwise, device creation fails.

You should check that you do have that `dll` in your system or you should reinstall the DirectX SDK. |

If anyone got any plan whats going wrong here, I really would appreciate your help, i just did not found any bugreport on that list on google nor a similar Bug.

] | I managed to solve this by using a listbox as the itemcontainer, and binding the expander items to it:
```
<Controls:ExpanderView Expanded="ExpanderView_Expanded"
Header="{Binding}"
HeaderTemplate="{StaticResource HeaderTemplate}"
NonExpandableHeader="{Binding}"
ExpanderTemplate="{StaticResource ExpanderTemplate}"
NonExpandableHeaderTemplate="{StaticResource NonExpandableHeaderTemplate}"
Expander="{Binding}"
>
<ListBox ScrollViewer.VerticalScrollBarVisibility="Disabled" ItemTemplate="{StaticResource ItemTemplate}" ItemsSource="{Binding Items}" />
</Controls:ExpanderView>
``` | I had similar problem with the ExpanderView. I think it could be a bug in the view, somehow related to the 2048px limitation. Basically when I added lot of items to an expanded ExpanderView everything was fine untill I collapsed the view and expanded it again. After expanding the ExpanderView, any items after the 2048 pixel where not shown unless i tapped them or scrolled it and even then they were shown only for as long as they were on the move (the tap animation of the item was running or the list was on the move).
I noticed that if I added an item to the ExpanderView or removed one from it while it was expanded, the glitch went away until the next time I collapsed and expanded the item, so I made a quick work around to add and remove a dummy item to the view when ever it was expanded by using the Expanded- and LayoutUpdated- events of the ExpanderView. Basically this is what I did:
* Set state to indicate that expanding is in progress and store the view being expanded for later use. (in Expanded event handler)
* Wait untill all the Expanderviews' layouts are updated (use LayoutUpdated event handler to keep track on this)
* Add dummy item to the ExpanderView that was expanded (in LayoutUpdated event handler)
* Wait untill all the Expanderviews' layouts are updated
* Remove the dummy item (in LayoutUpdated event handler)
Ugly solution perhaps but best I could come up with. Hope it's some help in your problem.
Edit:
Doesn't help on that stopping line of the Expander thing. Just couldn't get that one to work.. |

$\mathtt{n=3:}$For tensors of type $(0,3)$ we can mimick the proof for $n=2$ to deduce skew-symmetricness. Suppose $T\_{pqr}$ is an isotropic tensor.

$$T\_{ijj}=\sum\_{p,q,r}R\_{ip}R\_{jq}R\_{kj}T\_{pqr}=R\_{ii}R\_{jj}R\_{jj}T\_{ijj}\text{( using the fact that R is diagonal)}\\

] | Actually WordPress reduce quality of image when you upload it via media uploader. WordPress has built in compression for JPG images. Whenever you upload an JPG/JPEG image to WordPress media library, WordPress will automatically compress your images to 90% of the original quality, this is intended to help your pages load faster and keep file sizes smaller.
You can disable image compression and force WordPress to keep maximum quality images with this function.
```
// Set image quality
function my_image_quality( $quality ) {
return 100;
}
add_filter( 'jpeg_quality', 'my_image_quality' );
add_filter( 'wp_editor_set_quality', 'my_image_quality' );
``` | Normally this might due to some discrepancy from default set values for image in functions.php in wordpress and check whether any default values is set for the images in that file. You also can set it manually in function.php file as below.
```
add_theme_support('post-thumbnails');
update_option('thumbnail_size_w', 200);
update_option('thumbnail_size_h', 200);
update_option('large_size_w', 650);

1. Save response as `html` file locally and open it in browser.
2. Get [Scrapy](https://scrapy.org/) framework and use `view(response)` from `Scrapy Shell`. The Scrapy option is handy but requires installation of the framework that can be an overkill for a one-time project.
There is also another(more robust) way to get results from Google Search by using [`Google Search API][2]` from SerpApi. It's a paid API with a free plan.

In our case, this is the "video-voyager" selector which contains data about the title, channel name, video link, description and so on.

] | Company X located outside a military base offer discounts to military as a form of marketing. They want to encourage a group of potential customers to use their store/service. In some cases they are competing with subsidized store on the base. In other cases their only competition is other stores outside the base. The smart ones also understand the pay structure of military pay to make it easier for enlisted to stretch their money for the entire month.

```

Here is a lot of good solutions, but I think, first of all, you should clean your project structure or tune PyCharm Django settings before setting `DJANGO_SETTINGS_MODULE` variables and so on.

**Try restarting the console.**
This is pretty embarassing, but it took me a while before I realized I had forgotten to do that.
Here's what happened:
Added a fresh app, then added a minimal model, then tried to import the model in the Python/Django console (PyCharm pro 2019.2). This raised the `doesn't declare an explicit app_label` error, because I had not added the new app to `INSTALLED_APPS`.
So, I added the app to `INSTALLED_APPS`, tried the import again, but still got the same error.
Came here, read all the other answers, but nothing seemed to fit.
Finally it hit me that I had not yet restarted the Python console after adding the new app to `INSTALLED_APPS`.
Note: failing to restart the PyCharm Python console, after adding a new object to a module, is also a great way to get a very confusing `ImportError: Cannot import name ...` |

For anyone else in this situation, I found my solution [in a GitHub issue](https://github.com/encode/django-rest-framework/issues/3262#issuecomment-147541598), which was to unset the `UNAUTHENTICATED_USER` setting in the [DRF settings](http://www.django-rest-framework.org/api-guide/settings/):

Set the variable to `your_project_name.settings` and that should fix the thing.
It seems like this error occurs, because PyCharm runs tests with its own `manage.py`. | After keep on running into this issue and keep on coming back to this question I thought I'd share what my problem was.
Everything that @Xeberdee is correct so follow that and see if that solves the issue, if not this was my issue:
In my apps.py this is what I had:
```
class AlgoExplainedConfig(AppConfig):
name = 'algo_explained'
verbose_name = "Explain_Algo"
....
```
And all I did was I added the project name in front of my app name like this:
```
class AlgoExplainedConfig(AppConfig):
name = '**algorithms_explained**.algo_explained'
verbose_name = "Explain_Algo"
```
and that solved my problem and I was able to run the makemigrations and migrate command after that! good luck |

] | I had this error today trying to run Django tests because I was using the shorthand `from .models import *` syntax in one of my files. The issue was that I had a file structure like so:
```
apps/
myapp/
models/
__init__.py
foo.py
bar.py
```
and in `models/__init__.py` I was importing my models using the shorthand syntax:
```
from .foo import *
from .bar import *
```
In my application I was importing models like so:
```
from myapp.models import Foo, Bar
```
This caused the `Django model doesn't declare an explicit app_label` when running `./manage.py test`.
To fix the problem, I had to explicitly import from the full path in `models/__init__.py`:
```
from myapp.models.foo import *
from myapp.models.bar import *
```

] | I just ran into this issue and figured out what was going wrong. Since no previous answer described the issue as it happened to me, I though I would post it for others:
* the issue came from using `python migrate.py startapp myApp` from my project root folder, then move myApp to a child folder with `mv myApp myFolderWithApps/`.
* I wrote myApp.models and ran `python migrate.py makemigrations`. All went well.
* then I did the same with another app that was importing models from myApp. Kaboom! I ran into this error, while performing makemigrations. That was because I had to use `myFolderWithApps.myApp` to reference my app, but I had forgotten to update MyApp/apps.py. So I corrected myApp/apps.py, settings/INSTALLED\_APPS and my import path in my second app.
* but then the error kept happening: the reason was that I had migrations trying to import the models from myApp with the wrong path. I tried to correct the migration file, but I went at the point where it was easier to reset the DB and delete the migrations to start from scratch.
So to make a long story short:
- the issue was initially coming from the wrong app name in apps.py of myApp, in settings and in the import path of my second app.
- but it was not enough to correct the paths in these three places, as migrations had been created with imports referencing the wrong app name. Therefore, the same error kept happening while migrating (except this time from migrations).
So... check your migrations, and good luck! | In my case, there was an issue with BASE\_DIR in settings.py This is the structure of the packages:
```
project_root_directory
└── service_package
└── db_package
├── my_django_package
│ └── my_django_package
│ ├── settings.py
│ └── ...
└── my_django_app
├── migrations
├── models.py
└── ...
```
It worked when updated the settings.py with:
```
INSTALLED_APPS = [
'some_django_stuff_here...',
'some_django_stuff_here....',
...
'service_package.db_package.my_django_app'
]
```
And BASE\_DIR pointing to the project root
```
BASE_DIR = Path(__file__).resolve().parent.parent.parent.parent.parent

The CREATE SCHEMA notation is supported because it was part of SQL-89. The AUTHORIZATION clause is used to determine the (default) 'owner' of the objects created with the CREATE SCHEMA statement. There is nothing to stop a single user running the CREATE SCHEMA statement multiple times, either consecutively or at widely different times (in any given database within an Informix instance).
```
CREATE SCHEMA AUTHORIZATION "pokemon"
CREATE TABLE gizmo (s SERIAL NOT NULL PRIMARY KEY, v VARCHAR(20) NOT NULL)
CREATE TABLE widget(t SERIAL NOT NULL PRIMARY KEY, d DATETIME YEAR TO SECOND NOT NULL)
;
CREATE SCHEMA AUTHORIZATION "pokemon"
CREATE TABLE object (u SERIAL NOT NULL PRIMARY KEY, i INTEGER NOT NULL)
CREATE TABLE "pikachu".complain (C SERIAL NOT NULL PRIMARY KEY, v VARCHAR(255) NOT NULL)
;
```
After the CREATE SCHEMA statement executes, there is no way of tracking that either pair of these tables were created together as part of the same schema; there's no way to know that `"pikachu".complain` was part of a CREATE SCHEMA statement executed on behalf of `"pokemon"`. There is no DROP SCHEMA statement that would necessitate such support. |
63,228,428 | I am getting error while writing this line of code:
```cs
double h = model.WorkHours.Value>=0 ? model.WorkHours.Value : "";

] | What happens when the condition is `false`? This:
```
double h = "";
```
A `string` value can't be set to a `double`. The default for a `double` would be a `0` instead:
```
double h = model.WorkHours.Value >= 0 ? model.WorkHours.Value : 0;
```
Or, as specifically as possible:
```
double h = model.WorkHours.Value >= 0 ? model.WorkHours.Value : 0.0d;
```
You could also rely on `default` if you like:
```
double h = model.WorkHours.Value >= 0 ? model.WorkHours.Value : default(double);
```
If you want the value to truly be *empty* then you might consider using a `double?` (shorthand for `Nullable<double>`):
```
double? h = model.WorkHours.Value >= 0 ? model.WorkHours.Value : new Nullable<double>();
``` | Because a double doesnt have `null` or blank string as an allowable value, if you really want the default value to be a `null` or blank string, you will need to do one of the following.
Use an optional type along with an explicit type conversion:
```
double? h = model.WorkHours.Value >= 0 ? (double?) model.WorkHours.Value : null;
```
Use a string:
```
string h = model.WorkHours.Value >= 0 ? model.WorkHours.Value.ToString() : "";

37,891,443 | EDIT: I never figured this out - I refactored the code to be pretty much identical to a Boost sample, and still had the problem. If anyone else has this problem, yours may be the more common shared\_from\_this() being called when no shared\_ptr exists (or in the constructor). Otherwise, I recommend just rebuilding from the boost asio samples.
I'm trying to do something that I think is pretty common, but I am having some issues.
I'm using boost asio, and trying to create a TCP server. I accept connections with async\_accept, and I create shared pointers. I have a long lived object (like a connection manager), that inserts the shared\_ptr into a set. Here is a snippet:
```
std::shared_ptr<WebsocketClient> ptr = std::make_shared<WebsocketClient>(std::move(s));
directory.addPending(ptr);
ptr->onConnect(std::bind(&Directory::addClient, &directory, std::placeholders::_1));
ptr->onDisconnect(std::bind(&Directory::removeClient, &directory, std::placeholders::_1));
ptr->onMessage(std::bind(&Directory::onMessage, &directory, std::placeholders::_1, std::placeholders::_2));
ptr->start();
```
The Directory has `std::set<std::shared_ptr<WebsocketClient>> pendingClients;`
The function for adding a client is:
```
void Directory::addPending(std::shared_ptr<WebsocketClient> ptr){
std::cout << "Added pending client: " << ptr->getName() << std::endl;
pendingClients.insert(ptr);
}
```
Now, when the WebsocketClient starts, it tries to create a shared\_ptr using shared\_from\_this() and then initiates an async\_read\_until ("\r\n\r\n"), and passes that shared\_ptr to the lambda to keep ownership. It crashes before actually invoking the asio function, on shared\_from\_this().
Call stack looks like this:
```
server.exe!WebsocketClient::start()
server.exe!Server::acceptConnection::__l2::<lambda>(boost::system::error_code ec)
server.exe!boost::asio::asio_handler_invoke<boost::asio::detail::binder1<void <lambda>(boost::system::error_code),boost::system::error_code> >(boost::asio::detail::binder1<void <lambda>(boost::system::error_code),boost::system::error_code> & function, ...)
server.exe!boost::asio::detail::win_iocp_socket_accept_op<boost::asio::basic_socket<boost::asio::ip::tcp,boost::asio::stream_socket_service<boost::asio::ip::tcp> >,boost::asio::ip::tcp,void <lambda>(boost::system::error_code) ::do_complete(boost::asio::detail::win_iocp_io_service * owner, boost::asio::detail::win_iocp_operation * base, const boost::system::error_code & result_ec, unsigned __int64 __formal) Line 142 C++
server.exe!boost::asio::detail::win_iocp_io_service::do_one(bool ec, boost::system::error_code &)
server.exe!boost::asio::detail::win_iocp_io_service::run(boost::system::error_code & ec)
server.exe!Server::run()
server.exe!main(int argc, char * * argv)
```
However, I get a bad\_weak\_ptr when I call shared\_from\_this. I thought that was thrown when no shared\_ptr owned this object, but when I call the addPending, I insert "ptr" into a set, so there should still be a reference to it.
Any ideas? If you need more details please ask, and I'll provide them. This is my first post on StackOverflow, so let me know what I can improve. | 2016/06/17 | [

] | This is just a 'this' binding issue. Put a console.log inside of your mouseOver and mouseOut methods and you'll notice that your state isn't changing.
There are many ways to bind the 'this' context in your class methods. I'll show you three ways to do it in this example (DO NOT do all three methods, just choose one).
```
import React from 'react';
import Eyecon from '../../static/eye.svg';
class Item extends React.Component {
constructor(props) {
super(props);
this.displayName = 'Item';
// 1. bind your functions in the constructor.
this.mouseOver = this.mouseOver.bind(this);
this.mouseOut = this.mouseOut.bind(this);
this.state = {
hover: false
};
}
// 2. bind it with fat arrows.
mouseOver = () => {
this.setState({hover: true});
}
mouseOut() {
this.setState({hover: false});
}
render() {
const { item, i } = this.props;
// 3. bind them in the render method (not recommended for performance reasons)
return (
<div className="grid-box" onMouseOver={this.mouseOver.bind(this)} onMouseOut={this.mouseOut.bind(this)}>
{this.state.hover ? (<img src={Eyecon}/>) : null}
</div>
)
}
}
export default Item;
```
Here's an explanation of different ways to bind your 'this' context in react using ES6 classes:
<http://egorsmirnov.me/2015/08/16/react-and-es6-part3.html> | Maybe it's because you have to bind `mouseOver` and `mouseOut` calls in order to use `this.setState` inside them.
Replace:
```
<div className="grid-box" onMouseOver={this.mouseOver} onMouseOut={this.mouseOut}>
```
with:
```
<div className="grid-box" onMouseOver={this.mouseOver.bind(this)} onMouseOut={this.mouseOut.bind(this)}>
