Ways to create a new local branch, tracking a remote branch

Create a new local branch with the same name as the remote one

git checkout <remote_branch_name>
git checkout -t <remote>/<remote_branch_name>

Create a new local branch with a different name to the remote one

Useful git aliases

Command-line graphical log viewer

This is invaluable if you've managed to get yourself in a muddle.

git config --global alias.graph git log --graph --oneline --decorate --all

Enumerable#with_props

This is a little monkey-patch to add a new method to Enumerable, #with_props.

You use it something like this:

[1, 2, 3, 4].each.with_props do |element, props|
   puts "First? #{props.first?}"

Penisnet

So. One of my housemates pranked me, and I decided to get my revenge. My revenge was 100% inspired by upside-down-ternet, and goes as follows:

1. Linux box running the ruby script below, which acts as a transparent proxy
2. iptables rules on the linux box route all port 80 requests through the proxy
3. arp poisoning routes all of the victim's traffic through the linux box
4. Proxy isn't actually transparent. It intercepts requests for images, and does some processing on them, blurring them and writing a rude word in the middle.

The following snippet might help detect evil merges which deleted a file.

$ for rev in `git rev-list --merges HEAD`; do del=`( git diff --name-only --diff-filter=D $rev^ $rev; git diff --name-only --diff-filter=D $rev^2 $rev ) | sort | uniq -u | tr '\n' ' '`; [ -n "$del" ] && echo "$rev $del"; done
