Linux Kernel 2.6.32 Released 195

diegocg writes "Linus Torvalds has officially released the version 2.6.32 of the Linux kernel. New features include virtualization memory de-duplication, a rewrite of the writeback code faster and more scalable, many important Btrfs improvements and speedups, ATI R600/R700 3D and KMS support and other graphic improvements, a CFQ low latency mode, tracing improvements including a 'perf timechart' tool that tries to be a better bootchart, soft limits in the memory controller, support for the S+Core architecture, support for Intel Moorestown and its new firmware interface, run-time power management support, and many other improvements and new drivers. See the full changelog for more details."

It's impossible to make an arcade/console game system emulator with any semblance of accuracy that can use SMP, or OS-provided and scheduled threads, for multi-chip emulation, unless the OS and CPU are specifically designed for *extremely* low overhead inter-chip synchronization, and even with that the performance benefit may not be worth it and you might as well just program an FPGA. :b Now, if you don't care so much about accuracy because games on newer systems are generally more tolerant of timing inaccuracies, SMP will help to a degree. And of course you could use queues and buffers to defer CPU-intensive processing whose results are unreadable(in any way, shape, or form) to the emulated program to another core, but that would result in significantly increased complexity and significantly hurt performance on non-SMP systems.

I'd go with a fanless 350MHz Pentium II, running Windows 98SE, with 256MB ECC RAM(some DOS apps flip out if you have that much extended memory, though), on an Intel BX-chipset motherboard(Asus P2B comes to mind). Go with a name-brand power supply like Antec, non-PFC(you do want to use it with a cheap UPS without worries over compatibility, right?), with a power rating of 500W or more(not that you need it, it will probably last longer if you don't push it as close to its limits). Install two large, quiet chassis fans from different manufacturers. I'd use a 5400 RPM laptop drive(will probably need a $5-$10 mount/connector adapter), or even 7200 RPM, 20-80GB or so, with a 5-year warranty. Too large and the BIOS will have problems, and you'd probably not use it anyway.

If you want something newer(and you may, as I'm not sure what the lifespan on older slot 1 motherboards are...), you may want to look into a fanless socket 370 VIA C3, running on an Intel BX2 motherboard(only because it supports ECC, you can see other chipsets that nominally support it here:

Oh, and don't get a cheapo $10 case. They'll warp and bend, and could conceivably short out your motherboard. Not to mention slice open your supple flesh. ;)

Everything in life can be a glitch from a certain point of view, no life form is "perfect".

Antibiotics act on the differences(chemical, structural, signal-pathways, etc.) between bacteria and human/animal cells. As long as differences exist, it will be hypothetically possible on a very abstract level to produce antibiotics, but that's assuming we can engineer increasingly complex custom molecules...or find new species to plunder. ;)

This is probably something not many people care about, but...It's a hell of a lot easier and cheaper to find an Athlon64 motherboard that supports(and actually does ECC) ECC memory. Think $50-$100 for an Athlon64 motherboard that does this, versus $200-$300+(original Asus Maximus Formula, Asus P5E WS Pro) for a Core 2 motherboard(has to have an X38 northbridge, unless you want to give up PCIe x16 with a server chipset). I don't think the currently released Core i7 processors with built-in memory controllers support ECC *at all*.

(PS to trolls: Unbuffered ECC memory is only marginally more expensive than unbuffered non-ECC, though it usually has a small latency penalty. Registered/FB-DIMMs ECC on the other hand are Quite Expensive)
