OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

How to use Tim Pope’s Pathogen

I’ll assume you are on Linux or Mac OSX. For Windows, replace ~/.vim/ with $HOME\vimfiles\ and forward slashes with backward slashes.

The idea

Vim plugins can be single scripts or collections of specialized scripts that you are supposed to put in “standard” locations under your ~/.vim/ directory. Syntax scripts go into ~/.vim/syntax/, plugin scripts go into ~/.vim/plugin, documentation goes into ~/.vim/doc/ and so on. That design can lead to a messy config where it quickly becomes hard to manage your plugins.

This is not the place to explain the technicalities behind Pathogen but the basic concept is quite straightforward: each plugin lives in its own directory under ~/.vim/bundle/, where each directory simulates the standard structure of your ~/.vim/ directory.

To remove a submodule you need to:

Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule

Open Sublime Menu → Tools → Build System → New Build System...
Paste this code:

{
  "cmd": ["babel-node", "$file"],
  "selector": "source.js",
  "path": "/usr/local/bin:$PATH", // ENV setting for mac users
  "quiet": true // get rid of annoying `[Finished in %fs]`
}

Unit testing Angular.js app with node.js, mocha, angular-mocks and jsdom	unit-testing-angular-js-app-with-node	2015-07-05T18:04:33Z	en	Majority of search result about unit testing Angular.js apps is about how to do it by using test frameworks that run the tests in a real browser. Even though it's great to be able to test your code in multiple platforms, in my opinion it creates a lot of boilerplate code and makes it hard to run the tests in, for instance a CI-server.

Testing Angular.js app headlessly with node.js + mocha
