Yellow Dog Linux Finds New PPC Hardware Vendor 196
inditek writes "C|Net's News.com reports that Terrasoft Solutions, the vendor that sells and contributes to the development of Yellow Dog Linux has found, and continues to look for, some hardware alternatives based around the PowerPC now that Apple is moving to Intel chips. They say Apple's move makes for a good opportunity and more open space for a chip they think has a lot of life left in it." team99parody also writes "This is great news for customers like the US Navy who rely on Linux-on-PowerPC for important tasks like sonar imaging systems."

These are server stuff specificly to use the Power 5 proccessors with a Linux-specific machine.
For example the low end of it is a Power 710 'express'. A rack mount system with a 1.65 ghz Power 5 proccessor with 36 meg cache(!), 2 gigs of RAM, and 2 73gig 10k SCSI drives.
Very fast, huge cache, ok amount of memory, ok fast harddrives. 4,500 USD
You can get dual proccessors for under 10k, which realy realy realy kicks the ass of anything you can get from Sun for that price range. The Power 5 systems with their 36meg cache and HUGE transistor counts blow the AMD opterons out of the water.
IBM does not have a OpenPower workstation, and does not have a OpenPower desktop though. These are server/database systems and it shows. They AIX workstations you can order, but have Linux installed on them instead if you wanted to, and those aren't much more expensive.
IBM's stuff has always been expensive though. I'd rather have a army of 3rd party manufacturers make PowerPC machines.
However I don't see much of a point, other then platform snobishness.
Personally I like my PowerPC lappy; a Apple Ibook, but it's the last one I'd buy because it's video card is the ATI 9200 and is the last supported by Open Source drivers.
There is the R300 project for newer cards, but I don't think that it's paticularly usefull at this point (although I am gratefull for it, don't get me wrong.)
Having a PowerPC machine realy drive home the values of having free software.
Free software is stable, it's cross-platform, and it 'just works'. All propriatory software runs like ass on my system, if at all. It's a night and day difference.
Trouble is, what is the advantage to PowerPC desktops over x86?
NONE that I see. The newer intel setups are faster, use less power, and are supported well by open source drivers.. much better then the overpriced apple hardware. The ibook when I bought it was vastly superior to all small Pentium 4-m systems aviable and was cheaper.. for the 12 inch long-lasting-battery form factor.
Since then Intel has surpassed it wholy with it's Centrino/Sonoma stuff.
(and beleive me, the x86 Apple stuff will be overpriced, too. I'd probably avoid it personally)
Truth is they are both proccessors, they do both the same thing. Other then price and speed, the differences are purely academic at this point when considuring their use with Linux. Both work fine, x86 allows propriatory applications easily, PPC doesn't.
To me they are on equal ground. If third parties start suppling powerpc laptops that are well supported by free software, I'd strongly considure it.. but otherwise I realy don't care to much.
IBM needs to realy get in gear about their Power systems otherwise they will simply lock themselves into a small high-end market with slowly, yet consistantly, shrinking share.
If the average geek AND the average developer can't have easy access to PPC machines then Linux will stop being cross platform in a few years. It's ineveitable, and there is nothing nobody can do about it. Most people don't have 5000 dollars to burn just to have a extra server in their basement, or feel like spending 1000 dollars for a slow ass machine of lesser quality then what they can by at walmart for 300 dollars.
The biggest hope for future PPC machine in my future will be the Sony PS3. If they release a Linux distro for it, I'll buy it in a second. At 3ghz with a limited core it will be somewhat faster then my aging AMD desktop and my 1.2ghz Ibook. The SPE's offer interesting possiblities and will be fun to mess around with, especially when it comes to things like ray tracing and whatnot. If Sony gets Nvidia to release drivers for it it can actually have the possibility of being a rather kick-ass Linux box, otherwise it will just end up being a nice toy.
