Semicolon

I use it. If you don't, read these:

• twbs/bootstrap#3057

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

Stop trying to be an expert at Rails.

Is it Hard?

# Runs a specified shell command in a separate thread.
# If it exceeds the given timeout in seconds, kills it.
# Returns any output produced by the command (stdout or stderr) as a String.
# Uses Kernel.select to wait up to the tick length (in seconds) between 
# checks on the command's status
#
# If you've got a cleaner way of doing this, I'd be interested to see it.
# If you think you can do it with Ruby's Timeout module, think again.
