Game Over For Sony and Open Source?
Glyn Moody writes "Sony has never been much of a friend to hackers, and its infamous rootkit showed what it thought of users. But by omitting the option to install GNU/Linux on its new PS3, it has removed the final reason for the open source world to care about Sony. Unless, of course, you find Google's new distribution alliance with Sony to pre-install Chrome on its PCs exciting in some way."
I love my PS3.
I love Linux.
Sony is the only console maker that DID support Linux.
They dropped the support because it was an rarely utilized feature and it was cheaper not to support it on the new model.
I run Linux on all my PCs (2 laptops and 4 desktops) but never installed it on my PS3 (despite having partitioned my upgraded hard drive with room for it). I never felt the need to do so. I run a media server on two of the Linux boxes and I don't need the PS3 to be a 7th general purpose computer when that is not it's intended function as one and not designed for that purpose.
This fanboy of Linux (and fanboy of Sony as well) doesn't care about the dropped support. I thank Sony for all the support up to this point and wish this platform continued success.
I used to work for Sony developing PS2 games. The number of people I met that cut their teeth writing code on the linux kit before getting into the business was exactly 0. I might have been the only person I knew who even had a modchipped PS2, everybody else just didn't care since they had the PS2Tool on their desk to do development. Sony is probably discontinuing offering Linux because it didn't spark the development push that they had hoped for. Still, I would think this would limit the number of supercomputer clusters that use PS3's. You'd think the marketing benefits of being a platform in the top 100 supercomputers would be valuable, but perhaps Sony is still willing to work with academic institutions to make this possible still.
My microwave oven doesn't run Linux, either, but it somehow manages to still be useful to me.
*whistles innocently*
Don't be too sure about that. I've worked on embedded systems on consumer devices, and you'd be amazed at what runs Linux these days. Hardware manufacturers really like NOT paying license fees & royalties for their embedded firmware.

The Slim PS3 might be more hackable without the hypervisor being around. Odds are greater that one could better unlock the power of the PS3 since there's no hypervisor restricting access to the hardware directly.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
Nobody uses the PS3 for supercomputing these days. The ugly secret of the PS3 is that its 'extreme performance' was mostly marketing. While it was fairly fast at release, it is ridiculously complex to code for. You're talking about a machine with 9 distinct memory spaces, 4 instruction sets and 3 compilers. And while Sony may market it as having '2 teraflops' of performance, it only has about 450gflops of total programmable computation power. The vaunted Cell processor only clocks in at around 250GFlops, which you get pretty easily with Core i7 (Nehalem)... and it's a LOT easier to get peak performance out of the Core i7. Let me repeat that for emphasis it is mindbogglingly simpler to get peak performance out of the Core i7. And if you're willing to spend more a little time and money to code to a specialized platform, GPU computing with CUDA (and OpenCL once it matures) spanks the Cell. You can buy multi-GPU machines from NVidia that are pushing 4 teraflops programmable.
Ultimately though, the biggest killer of the PS3 in supercomputing is all that power is single precision, and single precision only. You can get away with single precision SOMETIMES in scientific computing, but more often than not it's a deal breaker. Even when you can use single precision, it's often in a mixed precision context. The PS3 has no double precision support, and that kills it.
The PS3 is awesome on paper, but in reality it's just awful.
The guy that owned the xbox and compromised the xbox360 security, claimed the only reason that the ps3 was safe from pirates was because they let you run all your otherOS/homebrew stuff, it will be interesting to see if this happens or if
1) homebrew are happy using the older consoles
2) homebrew try but fail to cack it
3) pirates crack the new (weaker) ps3 without homebrew's help
IranAir Flight 655 never forget!
