I tend to open up several terminals when working on a project, so I usually want them to start in the same directory I’ve been working with. Stick this in your ~/.bash_profile to have your new terminal windows automatically cd to the directory you last used.

export PROMPT_COMMAND=’echo `pwd` > ~/.lastpwd’
cd `cat ~/.lastpwd [...]

Get rid of Facebook’s Awful Ticker

By On October 12, 2011 · Leave a Comment

It’s appropriately named Facebook News Ticker Remover. Now I just need to clear out the entire right column. And most of the newsfeed.

Api Tester now hosted on Github

By On October 5, 2011 · Leave a Comment

You asked me to pull without telling me which branch you
want to merge with, and ‘branch.master.merge’ in
your configuration file does not tell me, either. Please
