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

Installation

function slugify(text)
{
  return text.toString().toLowerCase()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(/[^\w\-]+/g, '')       // Remove all non-word chars
    .replace(/\-\-+/g, '-')         // Replace multiple - with single -
    .replace(/^-+/, '')             // Trim - from start of text
    .replace(/-+$/, '');            // Trim - from end of text
}

# After wondering how commands like curl showed a progress bar, with the very big help of
# Google, I decided to write a shell script to show a progress bar
#
# Having not done much shell scripting, I learned a few (very likely quite obvious) things:
#   * It looks much nicer to create the string to echo in a variable, then echo it.  If I echo'ed
#     each part of the string instead of concatenating it with the rest of the string, the cursor
#     jumped around quite a bit.
#   * 'let x=x+1' is a lot faster than 'x=`expr $x + 1`' (I have a feeling this is probably because
#     let is implemented directly in bash, instead of a separate command)

RetroPie, LED control, and you

I wanted LEDBlinky-style functionality out of my RetroPie cabinet. But I didn't need RGB control or magical frontend integration or anything like that. I had buttons with simple single-color LEDs.

I've got a simple control panel with six buttons per player. All I wanted was this:

• When I launch Street Fighter 2, all twelve buttons should light up.
• When I launch The Simpsons, only the first two buttons for each player should light up.
