Kevin Wolkober demoed his free app NYC Wi-Fi, which shows nearby Wi-Fi hotspots in NYC. The app draws on a set of data called NYC Open Data.

This was Kevin's first iOS project and his first experience with Objective-C. He drew on a number of open-source libraries which are mentioned on his slides.

• Kevin's slides.
• Tutorials by Ray Wenderlich. Either Kevin mentioned these as a resource he used, or someone recommended them; I forget which.
• CocoaPods. I think it was Anup who recommended CocoaPods as a way to manage the open-source libraries in Kevin's project. Anup definitely did vouch for CocoaPods during dinner afterwards.
• During open discussion, Brian Papa mentioned the Academy for Software Engineering, which teaches computer science to high school kids. They partner with the iMentor NYC program, which matches high school kids with adult mentors. You can apply to be a mentor on their web site.
• Someone mentioned this blog post by Daniel Pasco. Pasco lists a bunch of interview questions that he asks his coworkers at Black Pixel to use to gauge a candidate's iOS or Cocoa expertise. I think it's a good list, and a sobering reminder of my own shortcomings.
• I asked a question about Sparkle, assuming everybody knew what I meant. I had forgotten how many developers are iOS only.
