Re: World Community Grid

I also used to run BOINC on one of my desktop computers and it made it very very slow. Not because of CPU usage (BOINC handles that very well), but because of memory usage that made my computer swaps all the time.

Re: Sound generation for a synth app-should I OpenMax?

It would probably be simpler to use the ARM core for audio processing, so that you could just use any software optimized for ARM instead of having to learn OpenMax.

I've never used OpenMax, but according to some people in this forum it does not look very easy to use it.

Re: A DIY PoE solution

Maybe I don't understand what you are trying to do.

If you want to power your board with PoE, I understand you'd have to make some kind of RJ-45 to micro-USB cable.
