Someone(tm) can write a Nekochan client for IRIX. Done. :mrgreen:

Re: What pointless thing are you doing right now?

Backporting the new VSX acceleration in libpng to VMX/AltiVec. It actually required very few changes, mostly to deal with a couple new VSX intrinsics that AltiVec doesn't have.

Mmmm, vectors.

Re: Video acceleration on Power Macs / QuickTime / FCP

Very interesting. At least you found a solution that seemed acceptable. What were the RT issues with ProRes? Did AIC give you any performance improvements?

Re: HP9000 C8000 noise

Mine has a FireGL-UX, which I'm quite sure doesn't help the power consumption any.

Re: HP9000 C8000 noise

Thanks! I own a Quad G5 and an IBM 285, and if they are quieter than these, then it's ok. I find the 285 louder, but less annoying, than the G5. It's a more constant sound, without annoying interference and overlaps. My 285 idles at around 250W-300W, depending on its mood. I've not yet measured my ...

Re: HP9000 C8000 noise

A quiet low whoosh as jpstewart reported, even my dual 1.1GHz PA-8900 setup. Makes my Quad G5 even more obnoxious by comparison. They're very well-behaved machines in that respect. The real problem with it is it draws even more juice than the Quad. I clocked it pulling almost 450W once; even OpenPA ...

Re: SCSI fuse advice (or, how to kill a ThinkPad 800 with a SCSI2SD)

From Unitrode, a division of Initrode? </officespace>

Maybe, though that particular part seems too new to be in this unit. I've seen two-pin SCSI breakers on some unrelated systems. I haven't gotten a round tuit on the SCSI2SD yet.

Re: What pointless thing are you doing right now?

No, not really. Since it only implements sigmoidal activation right now it's limited mostly to binary inputs and outputs. ReLU should be vectorizable, though I'd want a leaky variant to avoid being locked at 0.0. I'm thinking of using this to give the central computer some better monitoring capabili...

Re: What pointless thing are you doing right now?

Created an AltiVec-accelerated neural network implementation. Even got the activation function to be vectorized (a simplistic approximation of the logistic function, and I'll add some easily vectorized others later). Still knocking some bugs out of the backpropagation, but the damn thing seems to wo...

Re: your latest purchase

Yeah, it was a little more than I wanted to spend, but these things obviously don't come up very often and it's in like-new condition. I want to bench the 7300 before and after so I haven't gotten a round tuit for installation yet. Hopefully this weekend. And I always find it surprising what upgrade...

Re: What I did over the weekend

Well, both. UAE got a lot faster on my G5 once they got the JIT working. It's pretty useable now.

Nice job though!

Re: your latest purchase

It's also a Sonnet. The urban legend is that Motorola sent them some 1GHz parts when they were out of the 800MHz ones, so Sonnet made a small run of the faster card. The various estimates of how many were made are all less than 200, and some dude on ePay had three of them in the original box! Compar...
