deciding among subprocess, multiprocessing, and thread in Python?
...had also another constraint: communication with other processes written in C++).
In your case I would probably go for multiprocess, as python threads, at least when using CPython, are not real threads. Well, they are native system threads but C modules called from Python may or may not release the ...
Is unsigned integer subtraction defined behavior?
...
@LihO: The only operator in C++ that is context-sensitive and acts differently depending on how its result is used is a custom conversion operator operator T(). The addition in the two expressions we are discussing is performed in type unsigned int, ba...
Why not use exceptions as regular flow of control?
...

What are the functional differences between NW.js, Brackets-Shell and Electron?
...'s not like DRM for Web -- JS programmers should be able to do anything as C++ programmers can do, including compiling the source code to machine code, when they develop native applications.

Should I pass an std::function by const-reference?
...
As usual in C++11, passing by value/reference/const-reference depends on what you do with your argument. std::function is no different.
Passing by value allows you to move the argument into a variable (typically a member variable of a c...
Singleton: How should it be used
... a new object instead of referencing an existing one? Since this is tagged C++, let's use an example from that language. Do you often accidentally write
std::ostream os;
os << "hello world\n";
When you intended to write
std::cout << "hello world\n";
Of course not. We don't need pro...
How should I unit test threaded code?
...
Tough one indeed! In my (C++) unit tests, I've broken this down into several categories along the lines of the concurrency pattern used:

Shortest distance between a point and a line segment
...wer mentioned is no longer the accepted one.
Here's some correct code, in C++. It presumes a class 2D-vector class vec2 {float x,y;}, essentially, with operators to add, subract, scale, etc, and a distance and dot product function (i.e. x1 x2 + y1 y2).
float minimum_distance(vec2 v, vec2 w, vec2 p...
