... may need).
If you're talking about other platforms, of course, this rule does not apply (but that "shebang line" does no harm, and will help if you ever copy that script to a platform with a Unix base, such as Linux, Mac, etc).

...ction" // returns true
It can be invoked as a function and essentially does nothing as shown here:
setTimeout(function() {
console.log('Start: ', Date.now());
Function.prototype();

opengl: glFlush() vs. glFinish()
... since the changes won't be visible until you swap the buffers.
glFinish does not return until all effects from previously issued commands [...] are fully realized. This means that the execution of your program waits here until every last pixel is drawn and OpenGL has nothing more to do. If you re...
Why does the C# compiler go mad on this nested LINQ query?
...ith overload resolution. Unfortunately, just supplying the type parameters doesn't help the situation (where it presumably still has to perform the type checking).
The following code, which should logically be the equivalent code from yours, after lambdas have been analyzed, compiles without issue:...

What's the difference between __PRETTY_FUNCTION__, __FUNCTION__, __func__?
...it is supported and only use __FUNCTION__ if you are using a compiler that does not support it (for example, Visual C++, which does not support C99 and does not yet support all of C++0x, does not provide __func__).
__PRETTY_FUNCTION__ is a gcc extension that is mostly the same as __FUNCTION__, excep...
How does Java Garbage Collection work with Circular References?
... the Immix collector, which is a region-based tracing collector (though it does also use reference counting). I'm not sure whether you're referring to that reference counting, or another collector that uses reference counting without tracing (I'd guess the latter, since I've never heard of Immix bei...
