It will be a theme throughout this project that many of the ideas embodied in Ruby on Rails and the "Convention over Configuration" decisions they have adopted, though widely accepted and used, are not actually very helpful and sometimes are the opposite of what this repository recomm...
How to build Qt for Visual Studio 2010
...pt (2010) link from your start menu, or even pin it to the taskbar (a good idea). This is a special command prompt which has all the variables set for building with Visual Studio 2010 tools.
Once within the command prompt, navigate to your extracted Qt folder using old-school DOS way, which means y...

The idea comes from this image taken from Bairui's collection of Vim infographics:
Vim also has <C-^> (or <C-6> on some keyboards)—the normal mode equivalent of :b#—to jump between the current buffer and the pr...
Resolve build errors due to circular dependency amongst classes
...{
A a;

You can see why the compiler can't deal with this - it has no idea what B is - it has never even seen the symbol before.
So let's tell the compiler about B. This is known as a forward declaration, and is discussed further in this answer.
// main.cc
class B;
#include "A.h"

Best practices: throwing exceptions from properties

But it is also generally considered to be a good idea to design your classes such that it is simply not possible to get an invalid object initially, or to put it into invalid state via normal means (i.e., always ensure full initialization in constructors, and try make metho...

Needing PYTHONPATH to be set is not a great idea - as with anything dependent on environment variables, replicating things consistently across different machines gets tricky. Better is to use Python 'packages' which can be installed (using 'pip', or distutils) in syste...
Why should we typedef a struct so often in C?
...ed C projects where this use of typedef to hide struct is considered a bad idea, the Linux kernel is probably the most well-known such project. See Chapter 5 of The Linux Kernel CodingStyle document for Linus' angry words. :) My point is that the "should" in the question is perhaps not set in stone,...
Should I always use a parallel stream when possible?
...allel easy.
However, just because its easy, doesn't mean its always a good idea, and in fact, it is a bad idea to just drop .parallel() all over the place simply because you can.
