Month: August 2010

Call for Presentations and Demonstrations at September 1, 2010 Meeting

Posted on Updated on

It’s that time again: here’s your chance to share your knowledge, wisdom, and experience with your fellow developers and others interested in Apple’s iOS.

Consider presenting both technical and non-technical topics. Anything related to iPhone and iPad app development and sales is worthy of consideration. Presentations from 10 to 45 minutes are absolutely welcome. If you’re interested but are having difficulty coming up with ideas, check out last month’s post and its updated follow-up.

If you’ve developed an app you’d like to show off, that’s great too!

Lastly, if you have any news developments or upcoming calendar events, please feel free to send them along as well.

Drop me a line at and we’ll schedule your presentation!

Seeking Phoenix-Area Developers of 3rd-Party Apps

Posted on Updated on

If you’re in the Phoenix metropolitan area and develop iOS apps for other people and companies and you’d like to potentially be contacted about business opportunities, I need your contact information.

Please provide the following:

  • Company name, if applicable
  • Contact name
  • Contact email
  • Contact phone
  • Website URL
  • A one-sentence summary of your services and/or primary focus.
  • Something to show that you are indeed local, like your address (which will not be passed onto the interested parties) or a local telephone number.

Update – Call for Presentations and Demonstrations August 4, 2010

Posted on

We’ve got one standard-length presentation and two short ones. It’s summer, so I know there are lots of other plans, but we could really use another couple of short presentations or app demos.

Please consider a doing a short presentation on any topic that might interest the group. Some ideas:

  • App Comparison: If you’ve tried to find the perfect app for a given need and have tried several, show us what you compared and how you made your decision.
  • Newbie Tech Presentation: Show us how to do a basic thing — no need to go into depth and all of the many ways something could be accomplished, just cover the basic concepts. There are lots of new developers and hope-to-be developers who attend every month.
  • Tips and Tricks: Everyone’s found clever tricks that make development easier. Maybe you have some working with XCode usability tricks. Perhaps you’ve figured out some tricky little things you can do with Interface Builder to make things easier. Or perhaps you struggled to work with some Cocoa bit because it was difficult to wrap your head around but you figured out a way to think of it that made everything easier.
  • Library: There are lots of great libraries/wrappers/code frameworks out there. Give us 10 to 20 minutes on things like ASIHTTPRequest, one of the JSON frameworks, the CocoaHTTPServer, the Three20 framework, etc.
  • App Demo: Give us 10 to 20 minutes about an app you’ve built or worked on. Let us know where it came from and any travails or successes you had while designing and developing it. As long as it hasn’t been demonstrated at Pi before and you were integral to its creation, show us what you’ve done!

Email me if you’re willing to spend a few minutes during the meeting helping us learn. Developers supporting developers is what Pi is all about.
