A Ruby script for collecting phone record statistics from a Facebook user data dump
#! /usr/bin/env ruby
# NOTE: Requires Ruby 2.1 or greater.
# This script can be used to parse and dump the information from
# the 'html/contact_info.htm' file in a Facebook user data ZIP download.
#
# It prints all cell phone call + SMS message + MMS records, plus a summary of each.
#
# It also dumps all of the records into CSV files inside a 'CSV' folder, that is created

git copr alias

I'd like to share some git aliases that you might find useful if you handle pull requests from others.

Add these to your ~/.gitconfig in the [alias] section:

copr = "!f() { git fetch -fu origin refs/pull/$1/head:pr-$1; git checkout pr-$1; } ; f"
prunepr = "!git for-each-ref refs/heads/pr-* --format='%(refname:short)' | while read ref ; do git branch -D $ref ; done"

Now you can "git copr #{pr_number}" (check out pull request is the mnemonic) and it will pull down the PR in a local branch of pr-#{pr_number} and check it out for you. To do it right, you must pronounce it "Copper" with a James Cagney gangster accent.
