I am happy to announce that I just received an e-mail from Qualcomm, that their AR SDK is available for commercial use (still FREE of charge). Now, get your iOS applications rolling at the App Store!

You can download the SKD here.

I am mostly writing this for my own reference, if I am going to need to rollback to an old commit in git again.


1) On your local repository find the commit you would like to rollback to with


git log


2) Then do a hard reset, that will delete all commits after the one you need


git reset -hard COMMITID


3) You must force the changes on the master(in my case GitHub) from the local repo, not from a clone!


git push -f origin master


Hope, this will save someone else’s time too.

Since I am collaborating with a friend of mine, building some small game projects for iOS, I started getting into Cocos2D Framework. And on my way of learning Cocos2D, I couldn’t pass all tutorials written by Ray Wedenrlich on the topic. Today I found out that he has released a very good walk through of how to build a really awesome Space Game and bought it without hesitation.  I am already on page 30 and I really like how clean and detailed his explanations are.

ManiaDev.com just reported the release of a free augmented reality iOS SDK from Qualcomm, it has been available only for Android devices for a while now, so I am pretty happy of the news. Going to play with it the next couple of days and post some observations.

PS: Quick update, judging from the samples, the SKD is rockin fast on my iPhone 4!

I have been always struggling with setting the right size and debugging my view frames, and if you code your UI and do not use Interface Builder, you know what I mean. So today I came by this cool library – Introspect. Basically, by pressing “Space” in the iOS Simulator, you could see various properties of your views.

Wired UK shared a great story about the success and the future of the Angry Birds “Empire”, definitely worth the read if you are starting or planing to get into the whole Mobile Apps Business.
