107,732 | I've tried researching this question myself, but the only data I can find is over huge timescales, like situations where the continents have reformed back into a Neo-Pangea.
I'm not looking for any real drastic changes in positioning, just relatively minor things like seas disappearing or continents slightly shrinking or pushing into each other.
Would there be any noteworthy changes at all, or would it be pretty much the same as today aside from some minor changes that wouldn't affect anything?
Let's just assume humanity suddenly stopped existing today for the purposes of the question, so they don't make any more changes to the world than they already have.
As always, I'm very grateful for any answers, and if you need anything clarified feel free to leave a comment and I'll do my best to clear things up. | 2018/03/23 | [

Global Warming would continue for a while, if for no other reason than approximately 2.5% of CO2 is sequestered per annum.

At that rate, it would take 14 years to return to a CO2 value of 280ppm.
But in the meantime,
1. much polar ice has disappeared, and blue ocean absorbs more energy than white ice, and
2. the permafrosts are thawing, releasing lots of methane, which an even stronger greenhouse gas. This northern warming is causing even more methane to be released, in a vicious cycle.
Thus, it's very possible that most of the Greenland icecap will be melted, and also Antarctica, raising the ocean levels by 70 meters. | "Is removing people sufficient to stop global warming?" Good question. Answer is not clear. If we have passed the tipping point for arctic permafrost collapse, arctic ocean being ice free in summer, then we may release huge amounts of methane clathrates.
On top of this while oil has to be pumped, natural gas is often under pressure. As distribuiton systems break down, more methane is released.
Net result: ALL of antarctica and Greenland melt over the space of that thousand years.
So we have an new continent free from ice in the south, we have a new archipelago of islands where Greenland was. We have new ecologies in the arctic regions, and the ocean shoreline moves in a bunch.

] | A millennium is a blink of an eye on a geological scale. But interesting things can happen in a blink of an eye. Even disegarding the changes which may happen as a result of the present climatological instability, small but important modification can occur here and there.
I have no idea of the geographical changes between today and 3000 CE; but I do know of *some* geographical changes between 1 CE and today, either because they happened in places in which I have a local interest, or because they are somehow important to various historical events, or because I found out about them by accident and found them interesting enough to remember.
Geographical changes during the last 1000 or 2000 years
-------------------------------------------------------
* While sea level is today not very different from what it was in the first century, *in some places the sea advanced or retreated considerably:*
+ Some cities which used to be seaports in the first century are now several miles inland. For example:
- In the Antiquity [Ephesus](https://en.wikipedia.org/wiki/Ephesus) and [Miletus](https://en.wikipedia.org/wiki/Miletus) were major ports on the Ionian coast; they are now several kilometers inland.
[](https://en.wikipedia.org/wiki/Miletus#/media/File:Miletus_Bay_silting_evolution_map-en.svg)
*The silting evolution of Miletus Bay due to the alluvium brought by the Maeander River during Antiquity. Map by Eric Gaba, available on Wikimedia under the CC-BY-SA-3.0 license.*
- Closer to me, in the Antiquity the city of Histria was a seaport on the western coast of the Black Sea. Now its ruins lay on the shore of a shallow lagoon, and the sea is kilometers away.

*Ancient towns and colonies in Dobruja; modern coastline shown as a dotted line. Map by Bogdan, available on Wikimedia under the CC-BY-SA-3.0 license.*
+ On the other hand, in some places the sea advanced. For example, what is now the [IJselmeer](https://en.wikipedia.org/wiki/IJsselmeer) in the Netherlands used to be a low-lying plain in the first century, with a large lake known by the Romans as [Lake Flevo](https://en.wikipedia.org/wiki/Lake_Flevo). In 1287, [Saint Lucia's flood](https://en.wikipedia.org/wiki/St._Lucia%27s_flood) broke through and submerged the former river [Vlie](https://en.wikipedia.org/wiki/Vlie), creating a large shallow gulf which was called the [Zuiderzee](https://en.wikipedia.org/wiki/Zuiderzee).
[](https://en.wikipedia.org/wiki/Lake_Flevo#/media/File:50nc_ex_leg_copy.jpg)
*The region of the Netherlands in the 1st century CE. Map by the Dutch Nationale Onderzoeksagenda Archeologie (www.noaa.nl), available on Wikimedia under the CC-BY-SA-3.0 license.*
Then in 1932 the long effort of the Dutch to build the [Afsluitdijk](https://en.wikipedia.org/wiki/Afsluitdijk) was brough to completion, and the gulf was separated from the sea and became a lake, which the Dutch then proceeded to drain in order to increase the territory of their country; and now the Netherlands has a new 1500 square kilometer province, called [Flevoland](https://en.wikipedia.org/wiki/Flevoland).
* Rivers sometimes change course dramatically. For me, the most spectacular example is the [Oxus](https://en.wikipedia.org/wiki/Amu_Darya), which is today known as the Amu Darya. Until the 16th century it used to flow into the Caspian Sea, through what is now the dry [Uzboy](https://en.wikipedia.org/wiki/Uzboy) valley; it then changed its mind, abandoned the Caspian and went to empty into the Aral Sea.
[](https://en.wikipedia.org/wiki/Uzboy#/media/File:XXth_Century_Citizen%27s_Atlas_map_of_Central_Asia.png)
*The old course of the Oxus (Amu Darya), when it flew into the Caspian Sea, marked as "Old Bed of the Oxus". Map from 1903, available on Wikimedia. Public domain.*
At the beginning of the 18th century, [Peter the Great](https://en.wikipedia.org/wiki/Peter_the_Great), emperor of Russia, sent prince [Alexander Bekovich-Cherkassky](https://en.wikipedia.org/wiki/Alexander_Bekovich-Cherkassky) to find the mouth of the Oxus, with the intention of establishing a trade route from the Caspian to Transoxiana. The prince dutifully mapped the coast and returned with the sad news that the river no longer flowed into the Caspian...
* Speaking of the [Aral Sea](https://en.wikipedia.org/wiki/Aral_Sea), the Soviet Union killed it in the 20th century. The former immense lake of 68,000 square kilometers is now a desert, the [Aralkum](https://en.wikipedia.org/wiki/Aralkum_Desert).
* Speaking of the Soviet Union and Transoxiana: in the 1930s the Soviet Union conceived a titanic project to *"divert the flow of the Northern rivers in the Soviet Union, which "uselessly" drain into the Arctic Ocean, southwards towards the populated agricultural areas of Central Asia, which lack water"* (Wikipedia). The [Northern River Reversal](https://en.wikipedia.org/wiki/Northern_river_reversal) eventually grew and grew, design and planning progressed through the 1960s and 1970s, so that by 1980 the Soviets were talking of diverting 12 major Siberian rivers into the Central Asian desert. They even envisaged using atomic bombs to move massive amounts of dirt speedily. Then the Soviet Union fell; but who knows?
* Speaking of using atomic bombs to dig canals, Egypt is considering a [plan to dig a canal](https://en.wikipedia.org/wiki/Qattara_Depression_Project) from the Mediterranean to the [Qattara Depression](https://en.wikipedia.org/wiki/Qattara_Depression), flooding it and creating a solar-powered 2000 megawatt hydropower plant.
[](https://en.wikipedia.org/wiki/Qattara_Depression_Project#/media/File:All_proposed_routes.PNG)
*All proposed routes for a tunnel and/or canal route from the Mediterranean Sea towards the Qattara Depression. Map by AlwaysUnite, available on Wikimedia under the CC-BY-SA-3.0 license.*
And yes, in the 1950s the international Board of Advisers led by Prof. [Friedrich Bassler](https://en.wikipedia.org/wiki/Friedrich_Bassler) proposed to dig the canal using atomic blasts, part of President Eisenhower's [Atoms for Peace](https://en.wikipedia.org/wiki/Atoms_for_Peace) program.
* The [Frisian Islands](https://en.wikipedia.org/wiki/Frisian_Islands) on the eastern edge of the North Sea are notoriously shifty, so that the approaches to the Dutch ports have changed considerably from the Middle Ages to the present. For example, the northern part of what is now the island of [Texel](https://en.wikipedia.org/wiki/Texel) was until the 13th century the southern part of the island of [Vlieland](https://en.wikipedia.org/wiki/Vlieland); it then left Vlieland and became a separate island, the [Eierland](https://en.wikipedia.org/wiki/Eierland); in the 17th century the Dutch reclaimed the land between the Texel and Eierland, and the two islands became one.
[](https://en.wikipedia.org/wiki/Eierland#/media/File:PaysBas_delisle_1743_fragment.jpg)
*Eierland when it was a separate island. Map from 1702, available on Wikimedia. Public domain.*
Geography is not static
-----------------------
The list could be very much expanded. The Panama Canal. The proposed Nicaragua Canal. The lockless Suez Canal, which has brought the marine life of the Red Sea into the Mediterranean. The Hot Gates of Greece. The shifting barrier islands off the coast of Texas. The absent-minded [Yellow River](https://en.wikipedia.org/wiki/Yellow_River) of China. The wandering lake [Lop Nor](https://en.wikipedia.org/wiki/Lop_Nur). The unstable coastline of England -- how many of the medieval [Cinque Ports](https://en.wikipedia.org/wiki/Cinque_Ports) are still ports, that is, if they exist at all?
Geography changes wherever you look closely. | You mention plate tectonics as a cause of change; there are others
* **Rising sea levels**. [Wikipedia has a map](https://en.wikipedia.org/wiki/Sea_level_rise#/media/File:6m_Sea_Level_Rise.jpg) from NASA about how a 6-meter sea level rise would change the world map. Current predictions seem to be something between 0.3m and 2.5m in the next hundred years, so 6m doesn't seem crazy over 1000 years.
* **Coastal erosion** can cause significant changes: for example, the [seashore at Hemsby](http://www.bbc.co.uk/news/uk-england-norfolk-43472150) in eastern England is receding at the rate of about 35 metres (115 ft) per year.
* [**Post-glacial rebound**](https://en.wikipedia.org/wiki/Post-glacial_rebound). During the ice age, ice-covered land was weighted down; it's slowly springing back. For example, much of Finland was underwater a few thousand years ago, even though sea levels were much lower. Southern England is pivoting downwards as Scotland rises, which will lower southern England by about 0.5m in the next thousand years.
* **Vulcanism** can and does create new islands.
* **Deposition** from rivers causes estuaries to grow out into the sea. |

Geography changes wherever you look closely. | In addition to the previously noted changes due to climate and normal geology, the sudden removal of humans a la Discovery Channel's [Life After People](https://www.history.com/shows/life-after-people) would quickly lead to the breakdown of electrical and mechanical infrastructure, including pumping stations (e.g., the [California Aqueduct](https://en.wikipedia.org/wiki/California_Aqueduct), [New Orleans' pumping stations](https://en.wikipedia.org/wiki/Drainage_in_New_Orleans), and the Netherlands' [pumping stations in Flevoland](https://www.visitflevoland.nl/en/on-expedition/heritage/pumping-stations-in-flevoland/)), with the obvious results. In the longer term (a few centuries at most, according to Discovery), the majority of earthen and concrete structures are likely to fail, which includes essentially all of the world's dams, dikes, and levees. Their collapses will cause significant flooding, erosion, and scouring of low-lying areas downstream, and some river channels will be changed significantly enough to still show the effects a millennium hence.
Earth's cities and highways are also likely to be largely buried in vegetation (again, per Discovery), with the result that urban and linear features that are prominent from the air or even space will become much harder to see.
The disappearance of humans will also eliminate agriculture and logging, which is likely to reduce silt and fertilizer runoff in most places, with at least some visible changes in watersheds. (For example, [mangroves](https://go.nasa.gov/2FY1CnO) can be expected to make a larger comeback in some rivers; clear-cut areas of the Amazon and other forests will recover to some extent; and a number of river deltas like the [Ebro's](https://go.nasa.gov/2Ik9OQV) will stop growing so quickly and may actually erode.) The Aral Sea may make a comeback as well.
Astronomy might also play a small part; according to [Wikipedia](https://en.wikipedia.org/wiki/Impact_event), there's about a 20% chance of an asteroid strike large enough to create a crater actually hitting land and doing so.
By the way, spacecraft, even the ISS, are too small to make much of a mark, and what little damage they do cause would be hidden by vegetation and weathering very quickly (years, or decades at most). |

* Speaking of using atomic bombs to dig canals, Egypt is considering a [plan to dig a canal](https://en.wikipedia.org/wiki/Qattara_Depression_Project) from the Mediterranean to the [Qattara Depression](https://en.wikipedia.org/wiki/Qattara_Depression), flooding it and creating a solar-powered 2000 megawatt hydropower plant.

And yes, in the 1950s the international Board of Advisers led by Prof. [Friedrich Bassler](https://en.wikipedia.org/wiki/Friedrich_Bassler) proposed to dig the canal using atomic blasts, part of President Eisenhower's [Atoms for Peace](https://en.wikipedia.org/wiki/Atoms_for_Peace) program.
* The [Frisian Islands](https://en.wikipedia.org/wiki/Frisian_Islands) on the eastern edge of the North Sea are notoriously shifty, so that the approaches to the Dutch ports have changed considerably from the Middle Ages to the present. For example, the northern part of what is now the island of [Texel](https://en.wikipedia.org/wiki/Texel) was until the 13th century the southern part of the island of [Vlieland](https://en.wikipedia.org/wiki/Vlieland); it then left Vlieland and became a separate island, the [Eierland](https://en.wikipedia.org/wiki/Eierland); in the 17th century the Dutch reclaimed the land between the Texel and Eierland, and the two islands became one.

Geography is not static
-----------------------
The list could be very much expanded. The Panama Canal. The proposed Nicaragua Canal. The lockless Suez Canal, which has brought the marine life of the Red Sea into the Mediterranean. The Hot Gates of Greece. The shifting barrier islands off the coast of Texas. The absent-minded [Yellow River](https://en.wikipedia.org/wiki/Yellow_River) of China. The wandering lake [Lop Nor](https://en.wikipedia.org/wiki/Lop_Nur). The unstable coastline of England -- how many of the medieval [Cinque Ports](https://en.wikipedia.org/wiki/Cinque_Ports) are still ports, that is, if they exist at all?
Geography changes wherever you look closely. | "Is removing people sufficient to stop global warming?" Good question. Answer is not clear. If we have passed the tipping point for arctic permafrost collapse, arctic ocean being ice free in summer, then we may release huge amounts of methane clathrates.
On top of this while oil has to be pumped, natural gas is often under pressure. As distribuiton systems break down, more methane is released.
Net result: ALL of antarctica and Greenland melt over the space of that thousand years.
So we have an new continent free from ice in the south, we have a new archipelago of islands where Greenland was. We have new ecologies in the arctic regions, and the ocean shoreline moves in a bunch.

Earth's cities and highways are also likely to be largely buried in vegetation (again, per Discovery), with the result that urban and linear features that are prominent from the air or even space will become much harder to see.

31,158,335 | I encountered a strange issue. It's Wednesday now, and:
```
DateTime date;
DateTime.TryParseExact(
"Wed", "ddd", null, System.Globalization.DateTimeStyles.None, out date); // true
DateTime.TryParseExact(
"Mon", "ddd", null, System.Globalization.DateTimeStyles.None, out date); // false

] | I *suspect* the problem is that you've got a very incomplete date format there. Usually, `DateTime.TryParseExact` will use the current time and date for any fields that aren't specified. Here, you're specifying the day of the week, which isn't really enough information to get to a real date... so I suspect that the text value is only being used to *validate* that it's a reasonable date, after defaulting the `DateTime` to "now". (In the cases where it does manage to parse based on just the day name, you end up with today's date.)
I've just done another test where we specify the day-of-month value as well, and that ends up with interesting results - it appears to use the first month of the current year:
```
using System;
using System.Globalization;
class Test
{
public static void Main (string[] args)
{
// Note: All tests designed for 2015.
// January 1st 2015 was a Thursday.
TryParse("01 Wed"); // False
TryParse("01 Thu"); // True - 2015-01-01
TryParse("02 Thu"); // False
TryParse("02 Fri"); // True - 2015-01-02
}
private static void TryParse(string text)
{
DateTime date;
bool result = DateTime.TryParseExact(
text, "dd ddd", CultureInfo.InvariantCulture, 0, out date);
Console.WriteLine("{0}: {1} {2:yyyy-MM-dd}", text, result, date);
}
}
```
Changing the system date to 2016 gave results consistent with finding dates in January 2016.
Fundamentally, trying to parse such incomplete as this is inherently odd. Think carefully about what you're really trying to achieve. | Why not use regex if you are wanting validating part of a date?

Regular samsaric mind is "flat", we see things and we interpret them non-ambiguously as per our ego's convictions.
Buddha's mind is "non-flat", it's not like it doesn't interpret at all, rather it produces a solution space of all possible and plausible interpretations at once. It's not a collection of individual distinct interpretations, more like a multidimensional gradient space.

There is no one who can govern. There are only realities which causing others.
So, the purification of understanding in realities is the only way to specify the using of "govern" word whether wrong or right using.
It's ok to say "governed by the mind" if the speaker realizing in every moment weather "there are only realities depending on other realities, nothing controllable itself".
It's wrong if the speaker don't realize even one moment, although the speaker avoid to say the word "govern".
**And that ability required proficient Jhana and Abhidhammic detail. The proficient Jhana let the practitioner see ultimate realities in very advance, abhidhammic detail. The abhidhammic detail are seeing the smallest reality more than atom, fastest arising&vanishing more than the light speed, more than trillion time in a second.**

> It often seems that ultimate reality is only available in the absence of thought, yet interactions, work and daily functioning requires thought.

The ultimate reality is every where either thinking or not. The mind can know only a reality or a concept per arising, however it's conascence-wisdom can understand both of them at the same moment.
So, the thought is the opposite of only Jhana.
However, the unwholesome is the opposite of the insight-meditation as well, so it is important to do Jhana for pausing the thought. Jhana is easier than the insight-meditation, less detail, so it is good in short term to stop the unwholesome mind.

"Curbing thought" is Jhana. Jhana is required but not all the time.
It's important for insight meditation weather "how deep in detail that you can see the realities?".
But it's important for Jhana meditation weather "how long time that you can pause the thought?"
However, both Jhana-meditation and insight-meditation are important to do. |

In practice this sort of open multiperspective is actually very helpful in everyday life. It makes one a lot less prone to being stuck in a box or getting into a conflict with others.

There is no one who can govern. There are only realities which causing others.
So, the purification of understanding in realities is the only way to specify the using of "govern" word whether wrong or right using.
It's ok to say "governed by the mind" if the speaker realizing in every moment weather "there are only realities depending on other realities, nothing controllable itself".
It's wrong if the speaker don't realize even one moment, although the speaker avoid to say the word "govern".
**And that ability required proficient Jhana and Abhidhammic detail. The proficient Jhana let the practitioner see ultimate realities in very advance, abhidhammic detail. The abhidhammic detail are seeing the smallest reality more than atom, fastest arising&vanishing more than the light speed, more than trillion time in a second.**
>
> It often seems that ultimate reality is only available in the absence of thought, yet interactions, work and daily functioning requires thought.
>
>

The ultimate reality is every where either thinking or not. The mind can know only a reality or a concept per arising, however it's conascence-wisdom can understand both of them at the same moment.
So, the thought is the opposite of only Jhana.
However, the unwholesome is the opposite of the insight-meditation as well, so it is important to do Jhana for pausing the thought. Jhana is easier than the insight-meditation, less detail, so it is good in short term to stop the unwholesome mind.

> How does one curb thought when it is uncertain as to whether there is utility in the thought and that it is necessary to follow that thought to achieve something? Wouldn't this mean that ultimate reality can't be accomplished?

"Curbing thought" is Jhana. Jhana is required but not all the time.
It's important for insight meditation weather "how deep in detail that you can see the realities?".
But it's important for Jhana meditation weather "how long time that you can pause the thought?"
However, both Jhana-meditation and insight-meditation are important to do. | You cannot, not at least until you are enlightened & choose to do so.
What you can do is cease identification with the thought; detach yourself from the one who is doing the thinking. Karma will still play out for you, things happen, situations occur, thoughts arise. You can't really stop this.
The waves still as a consequence of following the path, you cannot willfully curb thought. |

23,977,264 | I was wondering how I can initialize a `std::vector` of strings, without having to use a bunch of `push_back`'s in *Visual Studio Ultimate 2012*.
---
I've tried `vector<string> test = {"hello", "world"}`, but that gave me the following error:
>
> `Error: initialization with '{...}' is not allowed for an object of type "std::vector<std::string, std::allocator<std::string>>`

] | **The problem**
You'll have to upgrade to a more recent compiler version (and standard library implementation), if you'd like to use what you have in your snippet.
*VS2012* [doesn't support](http://msdn.microsoft.com/en-us/library/hh567368.aspx) `std::initializer_list`, which means that the overload among `std::vector`'s constructors, that you are trying to use, simply doesn't exist.
In other words; the example cannot be compiled with *VS2012*.
* [**msdn.com** - Support For C++11 Features (Modern C++)](http://msdn.microsoft.com/en-us/library/hh567368.aspx)
---
**Potential Workaround**
Use an intermediate *array* to store the `std::string`s, and use that to initialize the vector.
```
std::string const init_data[] = {
"hello", "world"
};
std::vector<std::string> test (std::begin (init_data), std::end (init_data));
``` | **1. Why do I receive the error?**
Visual Studio 2012 doesn't support list initialization before the [2012 November update](https://support.microsoft.com/en-us/help/2797915/description-of-visual-studio-2012-update-1) according to this [question](https://stackoverflow.com/questions/12654394/initializer-list-not-working-with-vector-in-visual-studio-2012).
**2.Any ideas on what I can do to store the strings?**
Using push\_back() is a totally valid solution. Example:
```cpp
#include<vector>
#include <string>
using namespace std;
int main()
{
vector<string> test;
test.push_back("hello");
test.push_back("world");
for(int i=0; i<test.size(); i++)
cout<<test[i]<<endl;
return 0;

2. I think that Sabé was well-trained enough to handle the situation. They were out of danger, and she could couch any major decision she was pressed for as "I need some time to think about it", huddle with Padme, and there you are. If you've cultivated a habit of consulting your handmaidens *anyway*, this seems perfectly logical - I suspect that the handmaidens are probably noble-born and highly educated as well. | I always thought it was Sabe playing a joke on her friend the Queen. The Queen and her handmaidens are supposed to be very close (look at how distraught Padme was when Corde, who wasn't even HER handmaiden was killed) so maybe Sabe felt secure enough in their friendship to make her do dirty work.

An attendant to the Queen would be expected to be in attendance to the Queen whenever possible and allows little time to just "hang out" as it were in that more free environment. But if she were given a task that would take some time, she could spend time getting to know the travelers more and perhaps gain more of their trust in return. | I always thought it was Sabe playing a joke on her friend the Queen.

### The ACE chord (e.g., mm. 9-13)
* Play the low A and E with the left hand.
* Play the middle C with the right hand.
[](https://i.stack.imgur.com/bgsda.jpg) ======> [](https://i.stack.imgur.com/62Gi9.jpg)
### The C#AE and DAF chords (e.g., m. 17)
* Move the C# and D up two octaves and play them with the right hand.
* Play the low AE and AF with the left hand.
[](https://i.stack.imgur.com/zCeq4.jpg)
[](https://i.stack.imgur.com/3kyxi.jpg)
### The FDA chord (e.g., m. 20)
There are two options for this chord:
* Like the ACE chord, move the topmost A to the right hand.
* Like the C#AE/DAF chords, move the low F up two octaves to the right hand.
### The F#ADA chord (e.g., mm. 64 and 66)
Here, too, there are two options:
* Omit the topmost A in the left hand. A is already both the lowest and highest pitch present, so this inner A can be safely left out.
* With some careful fingering, the inner A can be shifted to the right hand.

### The remainder of the piece
These same techniques can be applied throughout, with any octave displacement being adjusted to the octave in which the right hand is playing. In general it works best to move the highest left-hand note to the right hand. |

With CSS you can create different designs, switch between them, redesign the page, without altering the source code. To see the power of CSS, check <http://www.csszengarden.com/>, all the pages use the same HTML source, but with different CSS layout.
As @Shmiddty noted, if `img` is for embedded images (actual content, for example a gallery, or a picture for an article), and CSS is for design.
Also, the question you referred to, has nice list of all the use-cases: `When to use CSS background-image`. | One of the main points of *image replacement* is to use your site title in a `h1` tag for good SEO, and then hiding the text and replacing it with a custom logo.

] | You should use `Expression<Func<T, bool>>` as predicates on your interface and have the `RepositoryBase` implement that interface.
By only using `Func`, you won't get translation to L2E etc, but will have to enumerate the entire DB table before you can evaluate the `Func`.
The interface can be mocked, hence unit-tested without a physical db and also used with other ORMs.
It's generally prefered to keep `SaveChanges` and the `DbContext` in a separate `IUnitOfWork` implementation. You can pass the `UnitOfWork` to the repository constructor, which can access an internal property on the UOW exposing the `DbContext`.
By doing that you can share the same `DbContext` between repositories, and batch updates to several entity roots of different type. You also keep fewer open connections, which are the most expensive resource you have when it comes to DBs.
Not to forget they can share transactions. :)
Hence you should not dispose the DbContext in the Repository, the Repository really doesn't need to be disposable at all. But the UnitOfWork / DbContext must be disposed by something.
Also, ditch the `OrderBy` predicate to `FindBy`. Since you return an `IQueryable`, and use an `Expression` for the predicate, you can keep building the Queryable after the call. For instance `repo.FindBy(it => it.Something == something).OrderBy(it => it.OrderProperty)`. It will still be translated to "select [fields] from [table] where [predicate] order by [orderprop]" when enumerated.
Otherwise it looks good.

---------------------
If you need a generic repository class use IObjectSet for base type and implement it if needed (in production code it is not needed, in tests you can use an IList<> as backend).
Leek on the abstraction
-----------------------
Repositories aren't supposed to have Save method becouse if someone else is in a transactional moment in shared context then you (or the other guy) can trick each other. Please create an independent IUnitOfWork for this.
```
interface IUnitOfWork : IDisposable {
void Commit();
void Rollback();
}
interface IDataStore {
IUnitOfWork InUnitOfWork();
IObjectSet<T> Set<T>() where T : class;
}
using (var uow = _data.InUnitOfWork()) {
_data.Set<Order>.AddObject(order);
_data.Set<SomethingElse>.Remove(otherObject);
uow.Comit();
}
```
The tricky part is how you handles the transaction. I have created an ISession interface with some methods (BeginTransaction(), InTransaction, Commit(), Rollback()) and created a default implementation. In my default IUnitOfWork implementation the constructor recieves an ISession instance and starting a transaction with it. The ISession implementation has an inner counter to count how many other actor started it's own transaction. When an IUnitOfWork from the shared storage Commited the counter is decremented by 1 if someone says RollBack then everything is rolled back.
EDIT (Dec. 03)
--------------
Fixed the IUnitOfWork Dispose behavior: the default is Rollback() not Commit()
In this way you can test your code easily. |

```
Yoon: > foldr (\x y -> 2*x + y) o [a,b,c,d]
lamdabot: 2 * a + (2 * b + (2 * c + (2 * d + o)))

] | It's not surprising that the process is slow, because the algorithm you are using (with nested loop) has at least quadratic O(N\*N) time complexity, which with such size of data sets is really slow.
One way is to use LINQ `GroupBy` operator, which internally uses hash based lookup, hence has theoretically O(N) time complexity. So you group by `type_id` and for each group (list of elements with the same key) take the one with the maximum `price`:
```
var uniqueBuyList = buyList
.GroupBy(e => e.type_id)
.Select(g => g.OrderByDescending(e => e.price).First())
.ToList();
```
Of cource you don't need to sort the list in order to take the element with the max `price`. A better version is to use `Aggregate` method (which is basically `foreach` loop) for that:
```
var uniqueBuyList = buyList
.GroupBy(e => e.type_id)
.Select(g => g.Aggregate((e1, e2) => e1.price > e2.price ? e1 : e2))
.ToList();
```
Another non LINQ based way is to sort the input list by `type_id` ascending, `price` descending. Then do a single loop over the sorted list and take the first element of each `type_id` group (it will have the maximum `price`):
```
var comparer = Comparer<EveObjModel>.Create((e1, e2) =>
{
int result = e1.type_id.CompareTo(e2.type_id);
if (result == 0) // e1.type_id == e2.type_id
result = e2.price.CompareTo(e1.price); // e1, e2 exchanged to get descending order
return result;
});
buyList.Sort(comparer);
var uniqueBuyList = new List<EveObjModel>();
EveObjModel last = null;
foreach (var item in buyList)
{
if (last == null || last.type_id != item.type_id)
uniqueBuyList.Add(item);
last = item;
}
```
The complexity of this algorithm is O(N\*log(N)), so it's worse than the hash based algorithms (but much better than original). The benefit is that it uses less memory and the resulting list is already sorted by `type_id`, so you don't need to use `OrderBy`. | You should be able to use `Enumerable.GroupBy()` to do this fairly efficiently:
```
var grouped = buyList.GroupBy(item => item.type_id);
var uniqueBuyList = new List<EveObjModel>();
foreach (var group in grouped)
{
var combined = group.First();
combined.price = group.Max(item => item.price);
uniqueBuyList.Add(combined);
}
```
Or alternatively (but more difficult to read):
```
var uniqueBuyList = buyList.GroupBy(item => item.type_id).Select(group =>
{
var combined = group.First();
combined.price = group.Max(item => item.price);
return combined;
}).ToList();

] | API support for logical operators isn't shipped yet. Meanwhile there're several workarounds:
1. Define dimension that mimics **OR** behavior. In your case it's
```js
cube(`Employee`, {
// ...
dimensions: {
companyAndName: {
sql: `CONCAT(${company}, ' ', ${name})`,
type: `string`
}
}
});
```
2. Define segments. Those can be also generated: <https://cube.dev/docs/schema-generation>
```js
cube(`Employee`, {
// ...
segments: {
soft: {
sql: `${company} LIKE CONCAT('%', 'soft', '%') OR ${name} LIKE CONCAT('%', 'soft', '%')`
}
}
});
``` | this is how you do it
```
{
or: [
{
"dimension": "Employee.company",
"operator": "contains",
"values": [
"soft"
]
},
{
"dimension": "Employee.name",
"operator": "contains",
"values": [
"soft"
]
}
];
}

43,374,103 | Being rather new to socket programming and threading in general, my issue might be stemming from a misunderstanding of how they work. I am trying to create something that acts as both a client and a server using threading.
Following:
<https://docs.python.org/3/library/socketserver.html#asynchronous-mixins>
I created a client class to go with the server and executed both from a main class. The server supposedly launches normally and doesn't give any errors but when I try to connect from the client, it fails on the following:
```
# In client connection
sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
sock.connect((ip, port))
```
the error I am getting is:
```
Traceback (most recent call last):
File "./<project>", line 61, in <module>
client.start_client(serverInfo)
File "/home/<username>/Documents/Github/project/client.py", line 54, in <startclient>
<connectionMethod>(cmd)
File "/home/<username>/Documents/Github/project/client.py", line 112, in <connectionMethod>
sock.connect((remoteHOST,remotePORT))
ConnectionRefusedError: [Errno 111] Connection refused
```
Even when I modify the server from the code in the referenced python page (just to run on a specific port, 1234), and try to connect to that port with
```
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as sock:
sock.connect(('127.0.0.1',1234))
sock.sendall('Test message')
```
I get the same problem
```
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
ConnectionRefusedError: [Errno 111] Connection refused
```
Why is the server refusing connections? No firewall rules or iptables are in place, running the example that has the client and socket together as is from the site works but even removing the `server.shutdown()` line it still kills itself immediately.
Am I missing something?
The behaviour I am expecting is:
```
./programA
<server starts on port 30000>
```
```
./programB
<server starts on port 30001>
<client starts>
```
--- input/output ---
FROM CLIENT A:
```
/connect 127.0.0.1 30001
CONNECTED TO 127.0.0.1 30001
```
ON CLIENT B:
```
CONNECTION FROM 127.0.0.1 30000
```
Basically once the clients connect the first time they can communicate with each other by typing into a prompt which just creates another socket targeting the 'remote' IP and PORT to send off the message (instant messaging). The sockets are afterwords left to close because they aren't actually responsible for receiving anything back.
I would appreciate any help I can get on this. | 2017/04/12 | [

``` | Your `<p>` and `#currState` are block level elements, meaning they will take up the full-width of screen and so naturally "Normal" will be on next line.
A hack fix would be to set both elements to `display: inline-block;` but I think your code could use a restructuring. You are using inline styles and `<br>` when not necessary and `<strong>` tags when you can just modify the `font-weight` in css, you have empty `<p>` tags, etc.
```
p {
display: inline-block;
}
#currState{

}

355,341 | Recently the Reopen Votes queue has been overrun with questions that have been closed, then edited by a user who is not the asker after the closure, and their edit has been approved.
95% of the time this happens, this approved edit does nothing to attempt to fix the question's content, but consists merely of formatting tweaks - which has the sole effect of (a) gaining rep for the editor (b) pushing the question into the Reopen Votes queue where shmucks like myself have to take a look at it to confirm that yes, it is still terribad and should never be reopened.
My procedure so far has been to go back to the stupidly-edited question and mod flag them with a comment that the edit is bad and whoever approved it should be review-banned, but seriously... that isn't instant, I have better things to do with my day, and I'm not the one who approved the bad edit and caused the problem in the first place, so why should I have to suffer?

* If a question is closed, and someone who is not the asker edits it after the fact, show a warning banner on the edit screen - something to the effect of "This question was closed due to serious problems; please do not edit it unless you are certain you can materially improve its content to make it answerable".
* If an edit in the Suggested Edits queue is for a closed question and was not performed by the asker of the question, show a warning banner on that suggested edit for that particular question to reviewers.
Please proceed to shoot holes in my suggestions and/or tell me I'm a terrible human being. You could also provide your own thoughts and suggestions on how this can be addressed, if you're feeling constructive. ;)

] | Here's a better suggestion: edits should only cause questions to go into the reopen queue if the OP is the editor.
Let's consider every possible close reason, and then decide who is more likely to make an edit that makes the question reopen-worthy:
* Duplicate: If the question is not a duplicate, the OP is the one who is most able to disambiguate it from the dupe-target.
* Off-topic/General Computing/Hardware: If the question is not hardware-related, the OP is the best person to be able to explain why this is not the case.
* Off-topic/Server: Ditto
* Off-topic/Recommendation: If a question looks like a recommendation question but is instead a "how to achieve X" question, it is possible that people who aren't the OP can explain the difference.
* Off-topic/MCVE: The OP is the person who has the code; therefore, they are in the best position to provide the code.
* Off-topic/No-Repro: Such questions usually don't get reopened. But if they do, it is usually by the OP providing further information/clarification. Which the OP is uniquely suited to do.
* Unclear: The OP is the person most likely to be able to provide sufficient information to clarify the problem. Others may be able to guess sometimes, but only the OP *knows*.
* Too Broad: The OP is the *only one* who can narrow it down. They're the only one who knows exactly what they're looking for.
* Opinion-based: The OP is the person most capable of finding a more objective form of their question. If someone else has a more objective form, they can ask it anew themselves.
Note that there are a lot of "most likely" equivocation in the above statements. Yes, I recognize that it is *possible* for other people to provide that information in those cases. So what?
If the OP is not engaged enough to fix the problem with their question themselves, then they're not really in a position to ask someone else to do it. Therefore, only edits by the OP should be considered when putting something in the reopen queue.
Furthermore, the OP already failed once. We need to teach the OP how to fix their question's problems. And that's not done by fixing them for them. By only considering OP edits, we make sure that other people coming along to fix it won't get the same effect. This rewards OPs who actually work to improve their questions. | >

This seems like wrong/harmful behavior to me for several reasons:
* First of all, it's not your job to request that moderators take a *specific action* against a user or users; moderators decide what punishment a rule breaker gets. Flagging a user for problematic behavior is one thing, but telling moderators to perform the most severe action on the user because their actions are merely annoying to you, personally, is a bit of an overreaction.
* You can't possibly know for sure in every case when the first close vote hit the question, vs when the suggested edit hit the review queue. In some cases you can tell if the suggested edit hit the queue *after* the question was closed, but a lot of the time, those edits are sitting there pending while the question is still open.
* To segue from my second point, users suggesting edits can't even *see* if a question is accruing close votes. You need 3,000 reputation to see them on others' questions. You gain the privilege for automatic edits 1,000 reputation *before* that.
* If you are concerned about your limited time being wasted in the queue, and you are getting frustrated with the stuff that enters the queue, perhaps *don't spend so much time in the queue*. The queue exists precisely to put reopen candidates under scrutiny.
Editing a post to clarify it, fix code that someone forgot to indent or tag (I see a lot of HTML/CSS posts that look nonsensical because someone added a lot of `<div>`s and `<p>`s in their prose and didn't put graves/backticks around them, so they don't show up in the post), or fix some other issue is one of several valid ways to get a question reopened, and it's working as intended when such edits land the question in the reopen queue.
*It's your job as an editor* to review these; that's the whole point of the queue! If you don't like those edits, or edits by someone other than OP, it takes but a second or two to hit "skip". |

] | Assuming that such edits were made by a person without edit privileges, each such harmful edit would have ended up in the suggested edit review queue. If so, the root of the problem lies there.
When doing suggested-edit reviews of questions, the reviewer needs to consider if the question makes sense in the first place!
There do exist rare cases where an edit from a 3th party could save a question from being closed. But apart from that exception, there is never a reason to edit a question that is closed/should be closed.
Editors who "polish crap" are a huge waste of everyone's time. In addition, they send out a signal to the OP that: "the question was fixed, so it is fine now". And also such edits could indeed spawn re-open reviews.
What I do when I encounter minor edits to bad/closed questions, is to reject with a custom reason, something along the lines of: "This question is `<close reason>` and cannot be salvaged by anyone but the OP. It should therefore get closed, not polished. Instead of trying to fix it, flag/close vote instead." | You know what? I'm not seeing it.

Here's how reopen review outcomes break down by [creation triggers](https://meta.stackexchange.com/questions/196074/lots-of-questions-in-the-reopen-queue/196078#196078) over the 365 days between September 3rd 2017 and September 3rd 2018:
```
CreationReason ReopenTasks % Reopened % Leave Closed % Edit % Task Invalidated % Questions now open
--------------------- ----------- ---------- -------------- ------ ------------------ --------------------
OwnerEditCreated 37734 4.49 % 76.85 % 0.21 % 18.44 % 7.25 %
ThirdPartyEditCreated 12284 1.28 % 88.51 % 0.07 % 10.14 % 2.43 %
Popularity 8746 4.71 % 82.38 % 0.16 % 12.75 % 6.69 %
VoteCreated 8127 6.77 % 81.97 % 0.17 % 11.09 % 13.65 %
```
The second column is the total number of tasks created for that reason during that time, the next 4 are the % of those tasks that were resolved in various ways ("invalidated" just means the review couldn't finish for some reason - including both the question being deleted or reopened outside of review).
Note that when I threw this together last night, I made two big mistakes: I ignored audits (which inflated the popularity trigger - though this also varies wildly over time, so also suffers from a small sample size) and didn't correctly account for edits that happened prior to the question being closed - those ended up skewing the results considerably.
So, yeah 3rd-party edits have an even worse success rate than you predicted; in two weeks, only 5 of them got reopened via review. OP edits - which account for the majority of all questions in reopen review - are a little bit better, but still mostly terrible. Even reopen votes from folks with 3K+ rep leave reviewers cold the vast majority of the time.
OTOH, the primary reason for putting this logic in place was to require a bit more work than simply [flagging to reopen](https://meta.stackexchange.com/questions/186722/can-we-have-the-ability-to-flag-for-reopening/186728#186728). In light of that, at least there's potentially *something* to work with, vs. an endless stream of folks asking for questions to be reopened where nothing has changed since they were closed.
As for bad edits... Don't forget that you can leave a comment on any edited post that @-pings an editor - if you haven't *told them* why their edits are lacking, you might want to try that first. | Maybe when a question is edited the person doing the edit should be asked if they wish to “vote to reopen”. Often even as the OP I may edit a question (for example a duplicate) to make it clearer, but not wish it to be reopened that that point.
So prompt for “should be considered to be reopened” on an edit, but don’t automatically assume it. The reviewers of the edit should get the same prompt and the question put in the reopen queue only if they also agree. |

* If a question is closed, and someone who is not the asker edits it after the fact, show a warning banner on the edit screen - something to the effect of "This question was closed due to serious problems; please do not edit it unless you are certain you can materially improve its content to make it answerable".
* If an edit in the Suggested Edits queue is for a closed question and was not performed by the asker of the question, show a warning banner on that suggested edit for that particular question to reviewers.
Please proceed to shoot holes in my suggestions and/or tell me I'm a terrible human being. You could also provide your own thoughts and suggestions on how this can be addressed, if you're feeling constructive. ;)

Here's how reopen review outcomes break down by [creation triggers](https://meta.stackexchange.com/questions/196074/lots-of-questions-in-the-reopen-queue/196078#196078) over the 365 days between September 3rd 2017 and September 3rd 2018:
```
CreationReason ReopenTasks % Reopened % Leave Closed % Edit % Task Invalidated % Questions now open
--------------------- ----------- ---------- -------------- ------ ------------------ --------------------
OwnerEditCreated 37734 4.49 % 76.85 % 0.21 % 18.44 % 7.25 %
ThirdPartyEditCreated 12284 1.28 % 88.51 % 0.07 % 10.14 % 2.43 %
Popularity 8746 4.71 % 82.38 % 0.16 % 12.75 % 6.69 %
VoteCreated 8127 6.77 % 81.97 % 0.17 % 11.09 % 13.65 %
```
The second column is the total number of tasks created for that reason during that time, the next 4 are the % of those tasks that were resolved in various ways ("invalidated" just means the review couldn't finish for some reason - including both the question being deleted or reopened outside of review).
Note that when I threw this together last night, I made two big mistakes: I ignored audits (which inflated the popularity trigger - though this also varies wildly over time, so also suffers from a small sample size) and didn't correctly account for edits that happened prior to the question being closed - those ended up skewing the results considerably.
So, yeah 3rd-party edits have an even worse success rate than you predicted; in two weeks, only 5 of them got reopened via review. OP edits - which account for the majority of all questions in reopen review - are a little bit better, but still mostly terrible. Even reopen votes from folks with 3K+ rep leave reviewers cold the vast majority of the time.
OTOH, the primary reason for putting this logic in place was to require a bit more work than simply [flagging to reopen](https://meta.stackexchange.com/questions/186722/can-we-have-the-ability-to-flag-for-reopening/186728#186728). In light of that, at least there's potentially *something* to work with, vs. an endless stream of folks asking for questions to be reopened where nothing has changed since they were closed.
As for bad edits... Don't forget that you can leave a comment on any edited post that @-pings an editor - if you haven't *told them* why their edits are lacking, you might want to try that first. | You know what? I'm not seeing it.
Out the 10 I've reviewed, not all where pushed to the queue with edits. The 6 which were, are done by users which fall in one of these two categories:

] | Maybe when a question is edited the person doing the edit should be asked if they wish to “vote to reopen”. Often even as the OP I may edit a question (for example a duplicate) to make it clearer, but not wish it to be reopened that that point.
So prompt for “should be considered to be reopened” on an edit, but don’t automatically assume it. The reviewers of the edit should get the same prompt and the question put in the reopen queue only if they also agree. | How about a ban on users that edit questions that get review rejected for:

] | Assuming that such edits were made by a person without edit privileges, each such harmful edit would have ended up in the suggested edit review queue. If so, the root of the problem lies there.
When doing suggested-edit reviews of questions, the reviewer needs to consider if the question makes sense in the first place!
There do exist rare cases where an edit from a 3th party could save a question from being closed. But apart from that exception, there is never a reason to edit a question that is closed/should be closed.
Editors who "polish crap" are a huge waste of everyone's time. In addition, they send out a signal to the OP that: "the question was fixed, so it is fine now". And also such edits could indeed spawn re-open reviews.
What I do when I encounter minor edits to bad/closed questions, is to reject with a custom reason, something along the lines of: "This question is `<close reason>` and cannot be salvaged by anyone but the OP. It should therefore get closed, not polished. Instead of trying to fix it, flag/close vote instead." | How about a ban on users that edit questions that get review rejected for:

* Conflicts with authors intent

] | It is necessary for you to tell us 3 things.
1. What command did you use to launch your ssh session.
Did you run
```
$ ssh -Y whatever.com
```
or
```
$ ssh -X whatever.com
```
If you had neither -X nor -Y, X11 forwarding won't work
2. Have you edited the ssh client configuration file on the client machine? If you changed that, tell us exactly what.
If you don't want to type -X every time you need X11 forwarding, it can
be set as default by editing /etc/ssh/ssh\_config. That's not the machine's server config, it is default for all clients. At the bottom of mine, I have
```
ForwardAgent yes
ForwardX11 yes
ForwardX11Trusted yes
```
I expect these changes will have no effect until you log out, but I may be wrong about that.
3. On the server machine, did you enable X11 forwarding?
On the server, in the file /etc/X11/sshd\_config, it will be necessary
to turn on X11 forwarding with a line like
```
X11Forwarding yes
```
Please note that change will not have an effect until the server is restarted, or at least its ssh server is restarted.
Let us know how that works. If it fails, report the config files and what you ran. | Have you disabled ipv6? If so I found the solution!
Add AddressFamily inet to sshd\_config.
Edit:
Perform the following steps:
1. On the server, edit the file /etc/ssh/sshd\_config .
2. The default file should have "AddressFamily inet" commented out. Uncomment it and change the value from its default of "any" to "inet".
3. Then restart the service: sudo service sshd restart . |

ATA/SATA drives should normally be detected on bootup. Look into the boot log (`/var/log/syslog, /var/log/messages`, output of `dmesg`).
There should also be a list of recognized partitions for all partitioned drives under `/proc/partitions`.
For hotplugged drives (e.g. USB) it depends on how the distribution manages them. Usually modern distros use udev (older might use hotplug or hald). The log is configurable, either a separate log under `/var/log`, or in the general log `messages` or `syslog`). |

ATA/SATA drives should normally be detected on bootup. Look into the boot log (`/var/log/syslog, /var/log/messages`, output of `dmesg`).
There should also be a list of recognized partitions for all partitioned drives under `/proc/partitions`.
For hotplugged drives (e.g. USB) it depends on how the distribution manages them. Usually modern distros use udev (older might use hotplug or hald). The log is configurable, either a separate log under `/var/log`, or in the general log `messages` or `syslog`). |

] | Haproxy is GPLv2, so you can redistribute it in binary form provided you give enough information to the end user about where to fetch the sources to rebuild it. You also need to inform them about the build options / environment, because without them, it's possible that they won't be able to get the same features.
When you have a doubt on those points, keep in mind that the GPL's goal is to ensure that if you disappear, your customers will not be left with a buggy software they can't fix. So you just have to provide them means not to depend on your availability. When you keep that in mind, it's a lot easier to make the right choice. And good faith always counts if you try to make this possible but fail because you've not thought about everything.
Also, keep in mind that whenever you start distributing software, some of your customers will ask for specific changes to better cover their needs. At first you'll refuse but after losing a few customers who all want the exact same minor feature, you'll accept. Then you'll have patched the code and be embarrassed because you won't be able to point the customer to the original site to get the code.
There are two approaches to this :
- the patch is of general use and you don't want to maintain it. Just submit it for inclusion into mainstream. If it's accepted, you can update your version and don't need to maintain a patch anymore ;
- the patch is too much customer-specific and has no chance of being accepted, then you need to make it available to your customer along with the build instructions so that the customer can still grab the official release, patch it and build it.
One possible typical patch is to remove some names/urls/versions etc in the doc to make it appear cleaner and better integrated with your solution. Removing these information is right if you provide the patch which removes them. That way there's no obfuscation, your changes are transparent.
In any case, if you spot a bug and think you fixed it, you're strongly encouraged to submit it for review, as it's common to fix the consequences instead of the causes. | If you're not modifying the source and using the binaries, you should be entirely in the clear. |

I strongly recommend you take a look at it.

You also need to inform them about the build options / environment, because without them, it's possible that they won't be able to get the same features.
When you have a doubt on those points, keep in mind that the GPL's goal is to ensure that if you disappear, your customers will not be left with a buggy software they can't fix. So you just have to provide them means not to depend on your availability. When you keep that in mind, it's a lot easier to make the right choice. And good faith always counts if you try to make this possible but fail because you've not thought about everything.
Also, keep in mind that whenever you start distributing software, some of your customers will ask for specific changes to better cover their needs. At first you'll refuse but after losing a few customers who all want the exact same minor feature, you'll accept. Then you'll have patched the code and be embarrassed because you won't be able to point the customer to the original site to get the code.
There are two approaches to this :
- the patch is of general use and you don't want to maintain it. Just submit it for inclusion into mainstream. If it's accepted, you can update your version and don't need to maintain a patch anymore ;
- the patch is too much customer-specific and has no chance of being accepted, then you need to make it available to your customer along with the build instructions so that the customer can still grab the official release, patch it and build it.
One possible typical patch is to remove some names/urls/versions etc in the doc to make it appear cleaner and better integrated with your solution. Removing these information is right if you provide the patch which removes them. That way there's no obfuscation, your changes are transparent.
In any case, if you spot a bug and think you fixed it, you're strongly encouraged to submit it for review, as it's common to fix the consequences instead of the causes. |

21,212,121 | I am new to jquery, Please help me resolve the below issue.
I have a modal popup and inside the popup i have two asp buttons(Search and close). Onclick of the search button i want to perform a validation and then fire the server button click event and on click of the close button i want to close the dialog.
**Problems faced:**
1. Onclick of search the jquery validation is happening but the server side event is not getting fired.
2. Onclick of close, the dialog is getting closed only for the first time but after click of the search button once, the close JQUERY is not getting fired.
**Below is the code:**
***button to open dialog***
```
<asp:Button ID="btnOpenDialog" runat="server" Text="Change"/>
```
***jquery to open dialog***
```
$("[id*=btnOpenDialog]").live("click", function () {
$("#modal_dialog").dialog({
title: "Details",
modal: true,
width: "700px"
});
return false;
})
```
***The dialog with the asp buttons***
```
<div id="modal_dialog" style="display:none">
<asp:Label ID="lblError" runat="server" Visible="true" ForeColor="Red"></asp:Label>
<asp:Label ID="lblLastName" runat="server" Text="Last Name"></asp:Label>
<asp:TextBox ID="txtLastName" Width="100px" runat="server"></asp:TextBox>
<asp:Label ID="lblFirstName" runat="server" Text="First Name"> </asp:Label>

<asp:Button ID="btnSearch" UseSubmitBehavior="false" runat="server" Text="Search" OnClick="btnSearch_Click"/>
<asp:Button ID ="btnClose" Text="Close" runat="server"></asp:Button>
</div>
```
***The btnSearch JQUERY***
```
$("[id*=btnSearch]").live("click", function (e) {
//e.preventDefault();
var firstName = $("#<%= txtFirstName.ClientID %>").val();
var lastName = $("#<%= txtLastName.ClientID %>").val();
if(firstName == "" & lastName == "")
{
$("#<%= lblError.ClientID %>").text("Enter minimum two characters in either first name or last name");
return false;
}
else
{
$("#<%= lblError.ClientID %>").text("");
$("#hdnFirstNameInitiator").val($("#<%= txtFirstName.ClientID %>").val());
$("#hdnLastNameInitiator").val($("#<%= txtLastName.ClientID %>").val());
return true;
}
})
```
***The close button JQUERY***
```
$("[id*=btnClose]").live("click", function (e) {
//e.preventDefault();
$("#modal_dialog").dialog('close');
return true;

] | Add a constructor
```
template <typename Type2> Pos2(const Pos2<Type2> &other)
{ x = other.x; y = other.y; }
``` | You need to define an assignment operator for assignment from type `Size` to type `Pos`, because these are not the same type and therefore there is no default assignment operator between the two.
I guess you want to use a template here, so any instantiation of `Pos2` can be used to assign to another instantiation. For example like so:
```
template<typename T>
class Pos2 {
public:
T x, y;
Pos2() : x(0), y(0) {};
Pos2(T xy) : x(xy), y(xy) {};
Pos2(T x, T y) : x(x), y(y) {};
template<typename FromT>
Pos2<T>& operator=(const Pos2<FromT>& from) {
x = from.x;
y = from.y;
return *this;
}
};
```
You should do the same with the copy constructor (not shown here), because it might likely happen that you want to copy construct in the same scheme at some point.
This does only work if the assignment between type `T` and `FromT`, that is `pos_scalar` and `size_scalar` is possible. If not try to add correct explicit conversions and/or template specializations for the assignment operator.
Also if any of the members of `Pos2` are private/protected you will need to `friend` the assignment operator or provide adequate getters. |
47,350,199 | Environment:
Asp Net MVC app(.net framework 4.5.1) hosted on Azure app service with two instances.
App uses Azure SQL server database.
Also, app uses MemoryCache (System.Runtime.Caching) for caching purposes.
Recently, I noticed availability loss of the app. It happens almost every day.

The memory counter Page Reads/sec was at a dangerous level (242) on instance RD0003FF1F6B1B. Any value over 200 can cause delays or failures for any app on that instance.

We could get the answer from this [blog](https://www.sqlshack.com/sql-server-memory-performance-metrics-part-3-sql-server-buffer-manager-metrics-memory-counters/). The recommended Page reads/sec value should be under **90**. Higher values indicate **insufficient memory** and **indexing issues**.
>
> “Page reads/sec indicates the number of physical database page reads that are issued per second. This statistic displays the total number of physical page reads across all databases. Because physical I/O is expensive, you may be able to minimize the cost, either by using a larger data cache, intelligent indexes, and more efficient queries, or by changing the database design.”

Based on my experience, you could have a try to [enable Local Cache in App

> By default, the local cache size is **300 MB**. This includes the /site and /siteextensions folders that are copied from the content store, as well as any locally created logs and data folders. To increase this limit, use the app setting **WEBSITE\_LOCAL\_CACHE\_SIZEINMB**. You can increase the size up to **2 GB (2000 MB)** per web app.

Memory counter values can be used to detect the presence of various performance problems. Tracking counter values both on a **system-wide** and a **per-process** basis helps you to pinpoint the cause in Azure such as in other systems.
Even if there is no change in the process, a change in the system can cause memory problems. the **system-wide**
**researching in the azure**:
Shared resources plans (Free and Basic) have memory limits as seen here: <https://learn.microsoft.com/en-us/azure/azure-subscription-service-limits#app-service-limits>.
**Quotas**: <https://learn.microsoft.com/en-us/azure/app-service-web/web-sites-monitor>
Also, you can check in the portal under your web app settings, search for “quotas”, and also check out “Diagnose and solve problems” and hit “metrics per instance (app service plan)” which will show you memory used for the plan.
A MemoryCache bug in .net 4 can also cause this type of behavior
