54,636,551 | I'm trying to get the length of my non list | I have this data I'm saving the player but I have one problem when I want to get the length of the "levels".

54,641,216 | Can scoped_lock lock a shared_mutex in read mode? | <p>C++17 introduced both <code>std::shared_mutex</code> and <code>std::scoped_lock</code>. My problem is now, that it seems, that <code>scoped_lock</code> will lock a shared mutex always in exclusive (writer) mode, when it is passed as an argument, and not in shared (reader) mode. In my app, I need to update an object <code>dst</code> with data from an object <code>src</code>. I want to lock <code>src</code> shared and <code>dst</code> exclusive. Unfortunately, this has the potential for deadlock, if a call to another update method with <code>src</code> and <code>dst</code> switched occurs at the same time. So I would like to use the fancy deadlock avoidance mechanisms of <code>std::scoped_lock</code>.</p>
<p>I could use <code>scoped_lock</code> to lock both <code>src</code> and <code>dst</code> in exclusive mode, but that unnecessarily strict lock has performance backdraws elsewhere. However, it seems, that it is possible to wrap <code>src</code>'s <code>shared_mutex</code> into a <code>std::shared_lock</code> and use that with the <code>scoped_lock</code>: When the <code>scoped_lock</code> during its locking action calls <code>try_lock()</code> on the <code>shared_lock</code>, the later will actually call <code>try_shared_lock()</code> on <code>src</code>'s <code>shared_mutex</code>, and that's what I need.</p>
<p>So my code looks as simple as this:</p>
<pre><code>struct data {
mutable std::shared_mutex mutex;
// actual data follows
};
void update(const data& src, data& dst)
{
std::shared_lock slock(src.mutex, std::defer_lock);
std::scoped_lock lockall(slock, dst.mutex);
// now can safely update dst with src???
}
</code></pre>
<p>Is it safe to use a (shared) lock guard like this inside another (deadlock avoidance) lock guard?</p>

54,660,606 | React w/hooks: prevent re-rendering component with a function as prop | <p>Let's say I have:</p>

<p>Any time I add an item, the <code><AddItemButton /></code> gets re-rendered because addItem is a new instance. I tried memoizing addItem:</p>
<pre><code> const addItemMemoized = React.memo(() => addItem, [setItems])

<p>But this is reusing the setItems from the first render, while </p>
<pre><code> const addItemMemoized = React.memo(() => addItem, [items])

const addItemMemoized = useMemo(() => () => {
items.push(Math.random());

54,670,251 | (Excel VBA) - Copy webpage content to a string | I need to access webpages and copy their content (everything) into a string which I will then extract some figures from.
The webpage address changes each time, as I am basically accessing an online simulation tool and I have to specify the sim parameters each time. And the outpit is always a string of about 320 characters. the web page consists ONLY in that text.
Example of web addess / query:

Note: I don't necessary need to save the string text on a document but it would be OK to do so if needed, and then open the file and retrieve my string.

54,683,922 | I want to sort the correlation between the residual of a time series regression and several prospective X independent variables | And, I want the correlations to be ranked by absolute correlation. And, I also want the output show the name of each X variable with its absolute correlation and its actual correlation (showing the sign).
Using the following codes I was able to calculate the correlation between the residuals (object res1) and the X variables (located within the data2 dataframe).
cor(data2, res1, method = c("pearson"))
The above code generated the output below that shows vertically in the console.
[,1]
x1 0.45683210
x2 0.62858863
x3 0.08457911
x4 0.41022052
Next, using the following code I was able to rank those correlations by their absolute value using the sort() function.
abs(cor(data2, res1, method = c("pearson")))
abs1<-abs(cor(data2, res1, method = c("pearson")))
sort(abs1, decreasing = TRUE)
And, I got the following output.
[1] 0.62858863 0.45683210 0.41022052 0.08457911
I want to generate an output that looks like a table or a dataframe. In the first column you would have the labels of the X variable, in the second column you would have their absolute correlation, and in the third column you would have the actual correlation with their sign. And, this vertical tabular list would be ranked in descending order. I think I have all the info I need. I just need the codes to generate the output as specified.

54,685,423 | Android - Use cases of Context in Android Development (Fragment, etc) | In the time I have spent learning Android Development, I have realized that the use of "Context" is a common theme in nearly everything we do.<br>
I recently read the following Article, and all of it's references: [What is it about Context](http://lomza.totem-soft.com/what-is-it-about-context-in-android/)?<br>
<br>
In addition to this being an informative resource regarding Context, I had an additional question, based on something it states..<br>
It says (and I quote): `(6) When in fragment, assign a context to the one from onAttach(Context context) method`<br>
<br>
**QUESTION (1) :** I am currently trying to adjust some Preferences using the `Preferencec-API` from within a `PreferenceFragment`.. In terms of `Context`, how should I go about this?<br>
**NOTE :** I am doing this from within `onPreferenceChangedListener`.<br>
<br>
**QUESTION (2) :** Is there a simple answer, or must I follow the instructions from the Quote I provided from the Link? And if so, how would I go about doing this, as my PreferenceFragment does not have any `onAttach` Method?<br>
<br>
**Many thanks in advance!**

54,689,361 | Avoiding Android navigation IllegalArgumentException in NavController | <p>I recently switched over to Android Navigation, but have encountered a fair amount of situations (in different parts of the code), where I get:</p>
<pre><code>Fatal Exception: java.lang.IllegalArgumentException
navigation destination com.xxx.yyy:id/action_aFragment_to_bFragment is unknown to this NavController
</code></pre>
<p>In every case, the code are simple calls like:</p>
<pre><code>findNavController(this, R.id.navigation_host_fragment).navigate(R.id.action_aFragment_to_bFragment)
</code></pre>
<p>Usually in response to a button press.</p>
<p>It's unclear why this error is getting thrown. My current suspicion is that the onClickListener is somehow getting called twice on some devices, causing the navigate to be called a second time (causing it to be in the wrong state at the time). The reason for this suspicion is that this most often seems to happen in cases where one might have a "long" running operation before the navigate call. I can't recreate this on my own device, though.</p>
<p>Ideas on how to avoid this issue (or indeed, what the actual root cause of the issue is)?</p>
<p>I don't want to use Global Actions; I'm wary of introducing even more unexpected states to the backstack. And I'd really prefer not to have to try and test for the currentstate every time a navigate call is made.</p>

54,694,970 | Index out of bounds after I've already accessed that index less than 10 lines ago | <p>I'm creating a little text dungeon crawler and each floor of the dungeon is a 2d array of rooms. for some reason when you get to the third floor, after creating the array and making sure all rooms are set to null, when I'm setting up the rooms as soon as I get to floor3[1, 0] it throws an index out of bounds.</p>
<p>Having used break points and looking at the array it clearly has a [1,0] as well as everything else between [0,0] and [9,6]. I run a for loop that accesses that index and sets it to null and tried changing the for loop to instead change all the rooms to test rooms and it had no problem with that. I checked probably a dozen times to ensure that there aren't any typos, or that I'm trying to call the wrong floor or anything simple like that. I also wrote just a simple Console.Writeline(floor[1,0]) test line to make sure that I wasn't just missing a typo, I removed that line and it also occurs on anything past that point. Again the identical method works for floors 1 and 2.</p>
<pre><code>floor3 = new RoomClass[9, 6];
//loop through everything and make sure that it's empty
for (int i = 0; i < 9; i++)
{
for (int j = 0; j < 6; j++)
{
floor3[i, j] = null;
}
}
//create rooms that actually need to exist.
floor3[0, 0] = new RoomClass("test1.", false, 0, 0);
floor3[0, 1] = new RoomClass("test2.", false, 0, 1);
floor3[0, 2] = new RoomClass("test5.", false, 0, 2);
floor3[0, 3] = new RoomClass("test3.", false, 0, 3);
floor3[0, 4] = new RoomClass("test4.", false, 0, 4);
floor3[0, 5] = new RoomClass("test5.", false, 0, 5);

54,697,030 | Excel 365 vba - (un)protect sheet slows down macro down a lot | Some employees of our company recently switched from office 2007 to office 365. It turns out that the execution time of VBA macros significantly increases in Excel 365. After analyzing the code it became apparent that this increase in time was exclusively caused by "ActiveSheet.(Un)protect"
To give a concrete example: a macro to insert a new line (including some formatting, inserting formulas, etc) increases in execution time from an average of 0.2889 seconds (Excel 2007) to an average of 1.7322 seconds (Excel 365). This difference (i.e. 1.4436 seconds) was caused by an increase in the execution time from (un)protecting the active sheet by 1.5175 seconds (!), which was offset by a slightly faster execution time of the rest of the code -0.0739 seconds.
Does anyone have the slightest idea as to why this is the case? And is there anything that can be done to resolve this without just omitting the protect-functions?

54,698,339 | for loop to get tapply means by group across many subjects | I'm trying to do some data analysis as follows: I have about 100 subjects, each of whom have a file containing 40,000 lines of numbers. I also have an index file with 40,000 corresponding lines containing group number. I am trying to get the means of each group, for each subject. I can do this easily for one subject with tapply, like this:
```tapply(df$numbers, df$group, mean)```
I can also load in a data frame containing the filenames of each subject's data. What I'd like to do is create a for loop in which I can get the output of the above tapply function for each subject, probably by looping over the filenames and pulling in each one as a new data frame (maybe??). And ultimately I'll want to output this to a .csv with subject names as rows and group names as columns.
Right now I'm very stuck. Can anyone provide some insight?
Thanks!

<p>The file <code>/scripts/config.toml</code> is the configuration as I created it in the ConfigMap.

<p>If if changing the <code>config.toml</code> via the ConfigMap does not work, how should I then change the configuration? I cannot find anything about this in Gitlab or Gitlab documentation.</p>

54,711,420 | JavaFX + FXML: Image dissapeared after converting project to Maven | I have a small JavaFX app. Everything looked fine, and was working fine. Suddently, I wanted to convert this project to a Maven project (I wanted to add some external dependencies and use them in the app).
In Eclipse I have right-clicked the project, selected `Configure` and then `Convert to Maven project...`. Everything went fine, until I have build and run the application. The whole app is working perfectly, but there was a logo in the app window, and after converting the project to Maven - the image has dissapeared.
I am using JavaFX with FXML and SceneBuilder.
In the `RootLayout.fxml` file, there is an entry:
<ImageView fitHeight="150.0" fitWidth="200.0" layoutX="225.0" layoutY="50.0" pickOnBounds="true" preserveRatio="true">
<image>
<Image url="@../../../../../../resources/images/nbtc.jpg" />
</image>
</ImageView>
It is still visible in `SceneBuilder` after conversion to Maven, but it has disappeared from the app after running it.
Here is the folder structure:

54,712,600 | What is the true maximum (and minimum) value of Random.nextGaussian()? | <p>In theory, the bounds for <code>nextGaussian</code> are meant to be positive and negative infinity. But since <code>Random.nextDouble</code>, which is used to calculate the Gaussian random number, doesn't come infinitely close to 0 and 1, there is a practical limit to <code>nextGaussian</code>. And <code>Random.next</code> is also not a perfectly uniform distribution.</p>
<p>It was theorised that the maximum should be about 2.2042*10^17 and related to the 53 bit shift of <code>nextDouble</code> (<a href="https://media.discordapp.net/attachments/508317357228294146/545718295408541716/unknown.png" rel="noreferrer">reference</a>), but that is likely just an upper bound.</p>
<p>The answer probably depends on the distribution of <code>Random.next</code> and the exact implementation of <code>StrictMath.sqrt</code> and <code>StrictMath.log</code>. I couldn't find much information about either.</p>
<p>And yes, I know that the outer values are extremely unlikely, but it can be relevant, for example in the context of RNG manipulation in games.</p>

54,713,411 | How to import data from a JSON into a Discord Bot Embed message? | I'm a complete dummy, trying to code a Discord.js bot without any prior coding knowledge. I'm trying to learn as I go. So, the project we are trying to make is a bot that will reply with a discord embed message. It's discord for an online game, where there are multiple different characters. Each of them have unique stats, skills and type. So the idea is to fill a JSON with all the information on all units, then have people use .unitname and have the bot reply with an embed will all information about that unit. This is how it should look like: https://i.imgur.com/Uc4F3En.png (sorry, I can't post images).
First of all, adding dozens of different commands for every single unit doesn't seem right, so I'm having the bot check every single message for a potential unit request. This does sounds pretty unoptimized for me, but will it slow down the bot in practice? And how would I code it to recognize something as .OneOfDozensOfPossibleUnits? Maybe I could have a separate list with all unit names, and have it trigger at .AnyOfThose, but is that the optimal way to do it?
Let's say the bot recognizes .Lucius as a unit request. He will have to look into the JSON file with dozens of units and gather data from Lucius specifically. How do I do that? Then I would have data saved, like stats, for example. Those would have to go in the places I called "variable" (check the code), but what's the syntax for that? I would also like to add some extra "if"s (for example, if unit type = "defense", make the color blue). This one I can probably search and find the syntax for, but I'd be really glad if you could include it.
Sorry, this is such a "do the work for me, please" post, but it can't be helped, haha. I would usually take my time and learn everything bit by bit, but since this is a community project, I'm going blind into a lot of areas. Please let me know if you have any other tips or if you found potential flaws in the program. Thank you in advance!

54,715,554 | Dart: Should I prefer to iterate over Map.entries or Map.values? | <p>Every time I need to iterate over the values of a <code>Map</code> in Dart, I contemplate the cost that this loop will incur, in terms of the complexity and the amount of garbage produced. There are two ways to iterate over the values of a <code>Map</code>: <code>Map.values</code>, and <code>Map.entries</code>. For example:</p>
<pre class="lang-dart prettyprint-override"><code>Map<String, Person> people;
int olderThan(int age) {
int result = 0;
for(Person p in people.values)
if(p.age > age) result++;
return result;
}
int olderThan2(int age) {
int result = 0;
for(MapEntry<String, Person> me in people.entries)
if(me.value.age > age) result++;
return result;
}
// Which one is faster: olderThan or olderThan2?
</code></pre>
<p>If <code>Map</code> stores its values internally as <code>MapEntry</code> objects, it's possible that <code>entries</code> would be just as efficient or even more efficient than <code>values</code>. The implementation details of <code>Map</code> are buried deep inside Dart libraries, so I wonder if anybody has this knowledge and can shed the light on this subject. </p>
<p>I understand that <code>Map.entries</code> gives you access to the key, but I am talking about cases where I don't need to use the key of the entry. I also understand that there are different implementations of <code>Map</code>. I am mostly interested in the default implementation, <code>LinkedHashMap</code>, but if it would be nice to know if there's a difference between the different <code>Map</code> implementations in this aspect. </p>

54,718,866 | Azure Pipeline Nuget Package Versioning Scheme, How to Get "1.0.$(Rev:r)" | <p>I'm setting up an Azure Pipelines build that needs to package a C# .NET class library into a NuGet package.</p>
<p>In <a href="https://docs.microsoft.com/en-us/azure/devops/pipelines/artifacts/nuget?view=azure-devops&tabs=yaml#package-versioning" rel="noreferrer">this documentation</a>, it lists a couple different ways to automatically generate SemVer strings. In particular, I want to implement this one:</p>
<blockquote>
<p><code>$(Major).$(Minor).$(rev:.r)</code>, where <code>Major</code> and <code>Minor</code> are two variables
defined in the build pipeline. This format will automatically
increment the build number and the package version with a new patch
number. It will keep the major and minor versions constant, until you
change them manually in the build pipeline.</p>
</blockquote>
<p>But that's all they say about it, no example is provided. A link to learn more takes you to <a href="https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/package/nuget?view=azure-devops" rel="noreferrer">this documentation</a>, where it says this:</p>
<blockquote>
<p>For <code>byBuildNumber</code>, the version will be set to the build number, ensure
that your build number is a proper SemVer e.g. <code>1.0.$(Rev:r)</code>. If you
select byBuildNumber, the task will extract a dotted version, <code>1.2.3.4</code>
and use only that, dropping any label. To use the build number as is,
you should use byEnvVar as described above, and set the environment
variable to <code>BUILD_BUILDNUMBER</code>.</p>
</blockquote>
<p>Again, no example is provided. It looks like I want to use <code>versioningScheme: byBuildNumber</code>, but I'm not quite sure how to set the build number, I think it pulls it from the <code>BUILD_BUILDNUMBER</code> environment variable, but I can't find a way to set environment variables, only script variables. Furthermore, am I suppose to just set that to <code>1.0.$(Rev:r)</code>, or to <code>$(Major).$(Minor).$(rev:.r)</code>? I'm afraid that would just interpret it literally.</p>
<p>Googling for the literal string "versioningScheme: byBuildNumber" returns a single result... Does anyone have a working <code>azure-pipelines.yml</code> with this versioning scheme?</p>
