Understanding garbage collection in .NET
...
Now run your program again and tinker with the source code. Note how the extra braces have no effect at all. And note how setting the variable to null makes no difference at all. It will always print "1". It now works the way you hope and expected it would work.
Which does leave with the task ...
ab load testing
...ach request is done, but to instead keep reusing it.
I'm also sending the extra header Accept-Encoding: gzip, deflate because mod_deflate is almost always used to compress the text/html output 25%-75% - the effects of which should not be dismissed due to it's impact on the overall performance of th...
Expand a random range from 1–5 to 1–7
...
Very nice! Can we retain the extra entropy without growing state? The trick is to notice that both upper- and lower- bounds are at all times rational numbers. We can add, subtract, and multiply these without losing precision. If we do it all in base-35, ...
In plain English, what does “git reset” do?
...repository.
But suddenly we came to know while commiting that we have one extra file which we added in index is not required to push in git repository. It means we don't want that file in index.
Now the question is how to remove that file from git index, Since we used git add to put them in the ind...
Microsecond timing in JavaScript
... more than 1,000 attempts. Only when I'm trying to do things like load an extra web page, or other, the millisecond accuracy degrades (And I'm able to successfully catch my own degraded accuracy by doing a before-and-after time check, to see if my processing time suddenly lengthened to 1 or more mi...
How to make a SIMPLE C++ Makefile
...
@jcoe It does an unnecessary extra preprocessor pass to generate dependencies. Doing unnecessary work it just dissipates heat melting the ice poles and, on a bigger scale, is nearing the heat death of our universe.

Why is volatile not considered useful in multithreaded C or C++ programming?
...ic operations necessary to implement a mutex; it only has volatile to make extra guarantees about ordinary operations.
Now you have something like this:
pthread_mutex_lock( &flag_guard_mutex );
my_local_state = my_shared_flag; // critical section
pthread_mutex_unlock( &flag_guard_mutex );

How to make a great R reproducible example
... and your code in the console and get exactly the same as you have.
Give extra information
In most cases, just the R version and the operating system will suffice. When conflicts arise with packages, giving the output of sessionInfo() can really help. When talking about connections to other appli...
Floating point vs integer calculations on modern hardware
...application. If you are developing for the x86 architecture, and you need extra performance, you might want to look into using the SSE extensions. This can greatly speed up single-precision floating point arithmetic, as the same operation can be performed on multiple data at once, plus there is a ...
