3 Very Useful Accelerometer And Vibration Code Snippets
The accelerometer can be one of the more confusing iPhone features to program. The input generally to be filtered, generally needs quite a bit of tweaking, and I’ve found that many people simply want too much out of the accelerometer.
iPhone for Programmers: An App-Driven Approach – Book Review
I have to admit to having a bias against the Deitel books primarily due to using the 1100+ page How To Program In C++ as a textbook in college. So when I first saw that Deitel had written iPhone for Programmers: An App-Driven Approach I waited awhile before checking it out since I had expected it to be another bible-sized reference book and not overly useful to self-learners. It turns out that this book was nothing like my expectations.
The Apple iPad – Is it just a big iPhone?
Now that the Apple iPad has officially been announced, it’s time to look at what sort of opportunities for app development have arisen because of this new hardware. If the name is making you giggle, that’s a natural reaction. At first glance the iPad looks like a big iPhone, here’s a rundown of the essential specs.
Apple iPad Hardware Specs (Known so far):
- 9.7″ Screen

Create App Trailers That Don’t Suck Without Jailbreaking
I’ve seen alot of crummy app trailers out there usually taken with a camera held or on a tripod, and thumbs in the way so I thought I’d mention this app. There’s been solutions to record the screen of a jailbroken iPhone for awhile, but this is a great "legit" solution. For those hobbyists that don’t want to spend the $99 to test their apps this is also a great tool.
iPhone 3GS Could Shape Up As Killer Gaming Device
As a developer I’ve been salivating over the released iPhone 3GS specs, here’s what we know so far:
2x the memory at 256MB (This itself is huge.)
Approx. 40% Faster processor (I didn’t really find this to be that big an issue but everything helps.)
OpenGL ES 2.0 support (Huge as this adds programmable shaders)
Compass (makes for much better accelerometer based controls)
Video (sometime support will apparently be added in the sdk)
PowerVR SGX chip (don’t know which one yet)
