I found today that Mobile Safari, the browser bundled with the iPhone, has a very strange and annoying behaviour when it comes to web apps.

Yes, it’s possible. Even if Objective-C is one of my preferred programming languages, in any case I think it’s worth mentioning that, 2 years after the official iPhone SDK has been announced, the iPhone development landscape has really grown up, and many, many different options are available today. This article provides a very high-level enumeration [...]

Nailing down the idea, the navigation and the UI of your next killer iPhone application is as important (if not more) as writing good code.

Alas, this is not the [...]

I’ve been doing presentations for a while now, so I decided to open a SlideShare account to publish all the slides I’ve created over the past 5 years. SlideShare has a great Flash-based viewer that you can embed in web pages, so I’ll be using it a lot now. Check out my presentations, feel free [...]

Another quick post to announce that I’ve published the slides (and sample application) I’ve shown last week in Copenhagen; feel free to download them from the projects section!
Remember that I’ll be hosting a similar talk on September 9th in Zürich! I look forward to see you there and to discuss about iPhone development.

Just a quick post to tell you all that I’ll be speaking tomorrow evening (August 27th, 2009) in Copenhagen (Denmark) in the free JAOO Geek Night organized by the great team of Trifork. They are the organizers of world-class events such as the QCon London, QCon SF and RubyFoo London!

But even better news for the [...]

Notitas is available at an App Store near you! Notitas means “small notes” in Spanish, and it’s the fourth iPhone application under the akosma brand, and the first based on an original idea of my dear wife!
