Code School Screencasting Framework

Screencasting Framework

The following document is a written account of the Code School screencasting framework. It should be used as a reference of the accompanying screencast on the topic.

Why you should care about screencasting?

You're probably aren't going to take the time to read this document if you're not interested, but there are a lot of nice side effects caused by learning how to create quality screencasts.

  1. Communicating more effectively - At Envy Labs we produce screencasts for our clients all the time. Whether it's demoing a new feature or for a presentation for an invester, they're often much more effective and pleasent than a phone call or screen sharing.

Re-style Sublime Text 2 sidebar to a darker theme

This re-styles your sublime text 2 sidebar to be darker, so it doesn't blind you when using a dark theme.

Dark sublime text 2 sidebar

Save the Default.sublime-theme file into packages/Theme - Default, make a backup of your original if you want to be able to go back easily.

Launch Sublime Text 2 from the Mac OS X Terminal

Launch Sublime Text 2 from the Mac OS X Terminal

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.

open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl

You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html

My git log custom output aliases 
git config --global alias.hist "log --pretty=format:'%h %ad | %s%d [%an]' --graph --date=short"
git config --global alias.lol "log --graph --decorate --pretty=oneline --abbrev-commit --all"
git config --global alias.mylog "log --pretty=format:'%h %s [%an]' --graph"

To check that they've been added correctly, first run git config --list. You should see something like this in the midst of all your other configuration:

alias.hist=log --pretty=format:"%h %ad | %s%d [%an]" --graph --date=short

How to migrate a Homebrew-installed PostgreSQL database to a new major version (9.3 to 9.4) on OS X. See upgraded version of this guide: http://olivierlacan.com/posts/migrating-homebrew-postgres-to-a-new-version/

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

Database rake tasks that I use on Code School to ferret out huge tables with millions of rows and see how many indices they have and to see which tables have missing indices on associated tables (foreign keys). The latter was taken from this great post by Tom Ward: https://tomafro.net/2009/09/quickly-list-missing-foreign-key-indexes
namespace :database do
task fat_tables: :environment do
c = ActiveRecord::Base.connection
max_table_name_width = 0
tables = c.tables.sort_by do |t|
max_table_name_width = t.length if t.length > max_table_name_width
