AMD’s talking more about its upcoming CPU Bulldozer than before. We now know that it implements simultaneous multithreading by not sharing execution resources as with Pentium 4/Core i7, but by actually doubling the execution resources.
Notice how the FP unit was unaffected, aside from the fact that it is now slightly more capable. Chalk it all [...]
Note: kboot does not support reiserfs. I don’t know about petitboot.
I finally gave in and installed Ubuntu, exactly what a n00b would do and not a Linux pro with 5 years of experience with Gentoo/Debian/Arch. It couldn’t be helped, since the Debian PS3 installer CD is so old it only recognizes the sid distribution and [...]
When I bought my PS3, it was under the assumption that I would use it as a computer, because while I do have 300EURs to blow on a PS3, I certainly don’t have 600EURs to spend on a good machine with at least 8GBs of RAM and four cores. And on top of that I [...]

So over the weekend I had some time to play around with my PS3 at last.
The GameOS, naturally, sucks. The web browser sucks. The photo viewer cannot play animated GIFs nor open PNGs in 5000×8000 resolution (I’d expect it to at least be flexible about that), the audio player does not recognize ID3v2/APEv2 tags in [...]
