I have an XFX board (with an NVidia 650i chipset) in one of my machines which has a similar problem. It reports the correct ACPI data to Windows (XP and Vista 64), but the ACPI data given to Linux specifies the wrong CPU frequencies.
Disabling speedstep makes the system work fine, but reduces power efficiency and increases heat and noise. I have tried very hard to get XFX to patch the BIOS, but they refuse to believe that it doesn't work. Their argument is "it works on Windows, so it's clearly a Linux bug". Looking at the DSDT shows different data on Linux and Windows, so it's pretty clear to me that the board's BIOS is doing something funny.
I haven't returned the board because it's not a critical problem, but it does annoy me.
How is polling the opinions of a diverse group of people with expertise in the field not "research"?
Sure, if he uses your ideas you will get referenced. Reading the ideas of others is an extremely important part of what research is. Just because I used Maxwell's equations in my PhD thesis, doesn't mean that it's his work and not mine. I cited the sources, and was entirely honest about which bits were mine and which were from somebody else. Then, in a seperate section, I discussed the importance of my contributions.
The work of others typically contributes the majority of the volume (and some of the value) of any PhD thesis or research paper.
I'm fairly certain they used deconvolution.
No, I'm fairly sure they didn't. Deconvolution is only applicable to linear systems - this "twirl" filter is non-linear. A better bet would be something like the reverse mapping approach mentioned elsewhere in this thread.
Valgrind's default memcheck tool is an excellent way of finding memory errors - ranging from extremely subtle to obvious. In addition, Valgrind can be used as a code profiler, cache simulator and many other things. It really is an excellent tool - I recommend it to anybody writing C++.
I know, why dont we pour molten steel all over ourselves and make really useful metal armour.
Especially good for impressing the judge after taking your medical aid to court for not paying for the third degree burns.
Things change, stuff gets cheaper. In the 50s and 60s you local crime syndicate would not have owned a computer, unless they stole one. in 40 years, this technology will be really cheap.

Mod Parent up.
For more info, I would recommend "Radar Cross Section" by Knott et. al. It's a great book, with some good info on radar absorbtion.

There are some problems that even the best technology can't solve.

Yes, and i bet that the Adam and Eve have a patent on the concept of "Apple", thus apple owe everybody on earth licensing fees. Just a thought.
