Android 2.2 on an old HTC Magic (32B)

Because of the bad weather I tried to update my old HTC Magic phone to the new Android 2.2 today: I wanted to have the latest and greatest Android features Wink. However, some tweaks were necessary to get a real nice performance. One has to go through long forum posts to optimize the system etc., therefore here is a short summary. (These tips might be also helpful on other old phones, like the G1)

Es gibt nämlich eine Vielzahl von kleinen Helfern, welche Google sicher lange nicht ersetzen werden, jedoch aber in speziellen Bere

Matrix Library Benchmark Follow-Up

It seems that many people start using the flens C++ matrix library for scientific computation because of my Sparse Matrix Library Benchmark article. This blog post should be a small add on and discusses possible difficulties with flens.
