56,196,399 | Is access to the heap serialized? | <p>One rule every programmer quickly learns about multithreading is: </p>
<p><em>If more than one thread has access to a data structure, and at least one of threads might modify that data structure, then you'd better serialize all accesses to that data structure, or you're in for a world of debugging pain</em>. </p>
<p>Typically this serialization is done via a mutex -- i.e. a thread that wants to read or write the data structure locks the mutex, does whatever it needs to do, and then unlocks the mutex to make it available again to other threads.</p>
<p>Which brings me to the point: the memory-heap of a process is a data structure which is accessible by multiple threads. Does this mean that every call to default/non-overloaded <code>new</code> and <code>delete</code> is serialized by a process-global mutex, and is therefore a potential serialization-bottleneck that can slow down multithreaded programs? Or do modern heap implementations avoid or mitigate that problem somehow, and if so, how do they do it?</p>
<p>(Note: I'm tagging this question <code>linux</code>, to avoid the correct-but-uninformative "it's implementation-dependent" response, but I'd also be interested in hearing about how Windows and MacOS/X do it as well, if there are significant differences across implementations)</p>

This tells me that myTest got slice as reference. But the later <code>append</code> of <code>"5678"</code> is not seen by the caller (main here) at all why its so? Remember the original slice is backed by an array with a capacity of 100. Why can't i see 5678 in main when the slice is passed by a reference?</p>

try
{
using (RegistryKey desiredKey = Registry.LocalMachine.OpenSubKey("SOFTWARE", true))
{
desiredKey.DeleteSubKeyTree("Policies");

The anticipated result is for the program to not give any exceptions and delete the subkey tree "Policies", but instead, it throws an "UnauthorizedAccessException" because the keys are in use.

Input streaming data from localhost:
ID Subject Marks
1 Maths 85
1 Physics 80
2 Maths 70
2 Physics 80
I would like to get the average marks for each unique ID's.
I tried this but not able to transform the DF which is a single value.
Below is my partial code:
from pyspark.sql import SparkSession
from pyspark.sql.functions import *
from pyspark.sql.types import *
spark = SparkSession.builder.appName("SrteamingMarks").getOrCreate()
marks = spark.readStream.format("socket").option("host",
"localhost").option("port", 9999).load()
marks.printSchema()
root
|-- value: string (nullable = true)
My expected output is just 2 columns (ID and Average Marks)
ID Average Marks
1 82.5

56,213,937 | Do i always need to use a container/container fluid in bootstrap? | <p>I was watching this video and the instructor said that bootstrap requires us to use a container/container fluid when using the grid system. However, she failed to always use a container even when she used the grid system. If you have 1 row and a bunch of columns that you make responsive, does that mean you are still using the grid system or does there need to be more than 1 row, since thats the case she didnt use a container and i was confused as to why she did not when bootstrap states we should use a container? I am a bit confused as when i should use a container in general and more importantly lets say i do not use a container and just use the grid system, what will end up happening?</p>

56,243,412 | Console application does not automatically open properly from regedit | Basically I have a console application that opens another .exe. That console application works properly when I normally double click on it.
I added the application in regedit: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run so that it automatically opens with Windows and that .exe is ran automatically.
I don't have an idea on how to fix this.
```cpp
#include <windows.h>
#include <shellapi.h>
#include <iostream>
using namespace std;
int main()
{
cout << "Test...\n";
Sleep(500);
cout << "Test..\n";
ShellExecuteA(NULL, "open", "Manager.exe", NULL, NULL, SW_SHOWNORMAL);
cout << "Test....\n";
Sleep(500);
return 0;
}
```
The thing is that the console opens when Windows starts up, but does not open the .exe file, just basically opens and closes. It's like bypasses the "ShellExecuteA"... line, displaying text on console and Sleep(...) works.
NOTE: Keep in mind that, as said above, it WORKS PROPERLY when I manually open this application, the "Manager.exe" opens. BUT I it doesn't work when this code is automatically opened with Windows. Any help? | <winapi> | 2019-05-21 17:19:01 | LQ_EDIT |

56,262,137 | Slow sass-loader Build Times with Webpack | <h1>Summary</h1>
<p>When we switched to using Webpack for handling our SASS files, we noticed that our build times in some cases became really slow. After measuring the performance of different parts of the build using the <a href="https://www.npmjs.com/package/speed-measure-webpack-plugin" rel="noreferrer">SpeedMeasurePlugin</a>, it seems that <a href="https://github.com/webpack-contrib/sass-loader" rel="noreferrer">sass-loader</a> is the culprit…it can easily take 10s to build (it used to take 20s before we made some fixes), which is longer than we’d like.</p>
<p>I’m curious if people have additional strategies for optimizing building Sass assets that I didn’t cover. I’ve gone through a fair number of them at this point (multiple times for some of them), and still can’t seem to get the build times low enough. In terms of goals, currently a large rebuild (such as making a change for a component used in many files), can easily take 10-12 seconds, I’m hoping to get it down closer to 5s if possible.</p>
<h2>Solutions Tried</h2>
<p>We tried a number of different solutions, some worked, others did not help much. </p>
<ul>
<li><a href="https://github.com/mzgoddard/hard-source-webpack-plugin" rel="noreferrer">HardSourcePlugin</a> - This one worked reasonably well. Depending on the caching for that build, it was able to reduce build times by several seconds.</li>
<li>Removing duplicated imports (like importing the same ‘variables.sass’ file into multiple places) - This also reduced build time by a few seconds</li>
<li>Changing our mix of SASS and SCSS to just SCSS - I’m not sure why this helped, but it did seem to shave a bit off our build times. Maybe because everything was the same file type, it was easier to compile? (It’s possible that something else was happening here to confound the results, but it did seem to consistently help).</li>
<li>Replace sass-loader with <a href="https://github.com/yibn2008/fast-sass-loader" rel="noreferrer">fast-sass-loader</a> - Many people recommended this, but when I got it to work, it didn’t seem to change the build time at all. I’m not sure why…maybe there was a configuration issue.</li>
<li>Utilizing <a href="https://github.com/webpack-contrib/cache-loader" rel="noreferrer">cache-loader</a> - This also didn’t seem to have any improvement.</li>
<li>Disabled source maps for Sass - This seems to have had a big effect, reducing the build times in half (from when the change was applied)</li>
<li>Tried using <code>includePaths</code> for SASS loaded from node_modules - This was suggested on a <a href="https://github.com/webpack-contrib/sass-loader/issues/296" rel="noreferrer">git issue</a> I found, where sass-loader had issues with something they called ’custom importers’. My understanding was that by using includePaths, SASS was able to rely on those provided absolute paths, instead of using an inefficient algorithm for resolving paths to places like node_modules</li>
</ul>
<p>From some brief stats, we appear to have about 16k lines of SASS code spread across 150 SASS files. Some have a fair amount of code, while others have less, with a simple average of the LOC across these files of about 107 LOC / file.</p>
<p>Below is the configuration that is being used. The application is a Rails application, and so much of the Webpack configuration is handled through the Webpacker gem.</p>
