'Here are the GWT sessions on the upcoming google i/o 2010 to keep an eye on. Google usually publishes the sessions on youtube and uploads the slides to the respective session homepage.

'I extended zTunes to handle VOB video files, and was able to push some tracks from DVD (ripped using DVDShrink) through zTunes to iTunes. Pretty nice, but I had to manually edit the ripped file names since ripping from DVD doesn’t include any metadata. Can anyone recommend a better way to rip from DVD to VOB, where one can more easily edit the track names before the rip so that the files get created with reasonable names? '…

'Pooling was initially introduced as a tuning action for the slow performance of object creation and garbage collection in particular. On a modern JVM > 1.4 pooling is no more needed for the optimization of memory management in a typical business application. It can even have a negative effect on the garbage collector performance. In special cases, like creating millions of instances in every method call, it could still pay off. Instance pooling, however is still interesting for objects with slow…

' This is a nice little book about the history of mathematics and the 350-year quest for the proof to Fermat’s Last Theorem.  It was written by the fellow who wrote the BBC / Nova TV special on Andrew Wiles, but includes a lot more information than a one-hour show could.  It does a nice job at hitting many of the high points of mathematical development from Pythagoras to modern day, including the “discovery” of zero, then negative numbers, then…
