Writing the XCode Cookbook

As some of you might know, I am writing an XCode Cookbook. This is a book which will contain only tutorials on how to do different things within XCode. So, no tutorials like “Adding Facebook to my iPhone app”, but more in the style like “Adding custom location to the iOS Simulator” or “Managing multiple targets within my project”.

I have a list of about 50-60 tutorials, but I need more. I need about 40 tutorials (3-4 chapters) more, so I am looking for tips; and since you, my readers, come here for such things, who better to ask but YOU!

An open letter to…

… all whom are or thinking of parsing the City Bikes data for Stockholm.

I felt I needed to write this post since I have been thinking about a “twitter” conversation I had a few weeks ago with some Spanish dude.

Since I have the sole right to the Clear Channel API’s for the Citybikes in Stockholm, I choose not to share these publicly with 3rd parties. This (off course) seems to annoy some people. Shortly after I received a question from an other developer regarding why I don’t want to share these publicly.
