Another fantastic crowd for the March Philly CocoaHeads meeting. Among our regulars, we are continuing to see lots of new faces who bring new input to the meetings, so thanks to everyone for coming. We encourage you to keep coming!

As always, we want to thank Indy Hall, our constant “sponsor” and provider of our great meeting space.

Meeting slides are online in keynote as well as pdf.

We had two excellent talks this meeting. The first, from Corey, was about git’s inner workings. Included in his talk was the recommendation of the “experimental” fork of the gitx client, as well as his current git cheat sheet, which Adam has posted as a gist. There was a lot of content to cover, so part 2 of this talk will be coming during one of our upcoming meetings.

Our second talk, by SiNae and Kostas of Amphetamobile, was an impressive demonstration of their latest iOS and web project, called Ink. You can see a video demonstration on youtube of their project.

We weren’t able to get to our planned QA Roundtable, so count on that showing up in in one of our next few meetings.

The next meeting will be Thursday, April 14th. As always, if you have something you’d like to present or demo let us know so we can get it on the agenda.

Also, don’t forget our upcoming “Office Hours” event, which will be held Wednesday evening, March 16th. More details will be coming shortly!

Thanks everyone!

After exchanging emails with a blind user of his iPhone app, Mike Zornek spent some time learning what VoiceOver is all about. Today, Mike will first demo VoiceOver use in general and then more specifically review the deficiencies of his iOS app and how he fixed them (some fixes more obvious than others).
