...
Node.js is built upon libuv, a cross-platform library that abstracts apis/syscalls for asynchronous (non-blocking) input/output provided by the supported OSes (Unix, OS X and Windows at least).
Asynchronous IO
In this programming model open/read/write operation on devices and resources (sock...
What are the Dangers of Method Swizzling in Objective-C?
...iting a bunch of code that's working directly with the Objective-C runtime API (in C), then it's nice to be able to call it C style for consistency. The only reason I can think of besides this is if you wrote something in pure C, then it's more still callable. There's no reason you can't do it all i...

That's 12 "dependencies" to deal with. For example, if screen resolutions get really huge, maybe we'll need 64-bit co-ordinate values - and another v...
Finding current executable's path without /proc/self/exe
...ry by Gregory Pakosz implements this for a variety of platforms, using the APIs mentioned in mark4o's post. This is most interesting if you "just" need a solution that works for a portable project and are not interested in the peculiarities of the various platforms.

Should I always use a parallel stream when possible?

The Stream API was designed to make it easy to write computations in a way that was abstracted away from how they would be executed, making switching between sequential and parallel easy.
