This project arose from a very specific need. An IRC channel I am often in has a decent number of drinkers. As a fun little project, I make an irc bot in Perl which tracks users estimated blood alcohol content over time. Since our weather bot was broken also, I interfaced with DarkSky to provide real time and forecasted weather. Use the bot yourself, or come chill with us in #alt.linux on Freenode (https://webchat.freenode.net/).
