Worst Commit – Ever

Got this via a friend and had to share this with you…

Ever heard of Bumblebee? Well I thought it was about this guy:

Apparently it wasn’t, in this case.

In fact, I still don’t even know what piece of software it is, but I do know about one of its most famous commits on github now.

This commit is very small, yet makes a very big difference for the user…

If you want to have a laugh see the commit yourself, and then all the comments, they are hilarous.

Ok, one teaser:

Still reading…?

Terminal: Show git branch, changes, RVM ruby version, gemset.

I was looking for a way to easily print the current gemset I am in when working in the terminal. I found a stack overflow post, but it did not really satisfy me. With some googling I also found this post.

I modified the script a tiny bit (color preferences + added __git_ps1 to detect branch) and would like to share you what I’ve got.

This is the complete script I use now, copy & paste if you like.

The result looks like this:


# This shows the git branch of the current directory
function __git_ps1 () {
git branch 2> /dev/null | sed -e ‘/^[^*]/d’ -e ‘s/* (.*)/ (1)/’

function __git_dirty {
git diff –quiet HEAD &>/dev/null
[ $? == 1 ] && echo " (changes!)"

function __git_branch {
__git_ps1 " %s"

function __my_rvm_ruby_version {
local gemset=$(echo $GEM_HOME | awk -F’@’ ‘{print $2}’)
[ "$gemset" != "" ] && gemset="@$gemset"
local version=$(echo $MY_RUBY_HOME | awk -F’-‘ ‘{print $2}’)
[ "$version" == "1.8.7" ] && version=""
local full="$version$gemset"
[ "$full" != "" ] && echo "$full "
