How to use terminal on Windows without going crazy…

Windows is really horrible system for developers and especially for devops. It doesn’t even have a usable terminal and shell, so working with command line is really pain in the ass. If you really don’t want to switch to any usable system (OS X, Linux, BSD…), then this guide should help you to setup somewhat reasonable environment – usable terminal, proper shell, ssh client, git and Sublime Text as a default editor for shell.

Install stuff

1. Download and install Git for Windows* with:
   • [✘] Use Git from the Windows Command Prompt

• [✘] Checkout as-is, commit Unix-style line endings

    this.id = id;
    this.instance = 'tf_' + (new Date().getTime());
    window[this.instance] = this;
};

TweetFetcher.prototype.fetch = function(cb, limit)
{
    this.cb = cb;

true and false vs. "truthy" and "falsey" (or "falsy") in Ruby, Python, and JavaScript

Many programming languages, including Ruby, have native boolean (true and false) data types. In Ruby they're called true and false. In Python, for example, they're written as True and False. But oftentimes we want to use a non-boolean value (integers, strings, arrays, etc.) in a boolean context (if statement, &&, ||, etc.).

This outlines how this works in Ruby, with some basic examples from Python and JavaScript, too. The idea is much more general than any of these specific languages, though. It's really a question of how the people designing a programming language wants booleans and conditionals to work.
