vBrownBag.com is in its second year of #Commitmas! While it's not well publicized, everyone should be attending these Commitmas sessions. Every weekday of December, vBrownBag has a new session on using GitHub and Git commands to teach newbs the very basics in commiting code.
We have pretty much different presenters every night and they're usually just nuggets of wisdom that don't last as long as a normal vBrownBag cast. Usually ranging from 10-30 minutes you'll see people who actually use GIT tell us the ins and outs. For more information, check out the GitHub site found here! If you missed the first half of December, just check out vBrownBag's YouTube channel for recordings.
