I would highly recommend not using STL on the SPUs....or in any gamedev situation... or at all really :P, google if you need reasons for this. (I beat this horse far too much) Care to beat that horse one more time? I'm curious why you don't like STL and why you think it's better to avoid it. I use ...

Maybe this is a stupid question, but why are you doing this kind of stuff from the PPU anyway? Regardless of how you're writing your code, your still doing ±50 million dword writes a second @25 fps, which will be pretty slow no matter how you do it.

The mesa sourcecode contains a lot of examples, just get the sources from www.mesa3d.org, unpack and check the examples directory. I think it was called Demos, but I'm not sure.

I haven't used the DVD drive from linux yet, but most likely it registers as /dev/scd0 or /dev/scsi/host0/bus0/targetX/lunY or something like that, or just as /dev/hdb or /dev/hdc. Check dmesg output and find the line that identifies the DVD drive to know for sure.

You cannot plaintext attack public/private key-pair encryption systems like used for the PS3 game code. Depending on the key size (probably 128 bit or more) it will take you somewhere between twenty thousand and 2 billion years before you hit the private key... On average... If you're using a superc...
