It's selection pressure. Companies that could use loopholes but don't are at a disadvantage in the marketplace to those that do. Similarly, politicians can improve their election chances by pandering to large corporations who ply them with campaign donations. That is, unless the electorate decides to penalize them for doing so and there is enough transparency in campaign financing to allow voters to reasonably decide.
Adobe Flash has been working on Linux for many years now. Only on some platforms like Ubuntu 10.04, Flash is a bit flaky. I'm running RHEL 5, and on that, Flash runs perfectly stable (the original ATI driver as well, btw).
I see your anecdotal evidence and raise you my anecdotal evidence. I've always had issues using the 64bit flash plugin on linux (on Fedora, Gentoo, and Ubuntu) with errant npviewer.bin processes using 100% cpu or crashing.
Will this "new, magical and unicorn-like" WiFi travel further? Far enough for municipal WiFi to effectively cover its citizens? If so then the increased coverage is more important than the speed improvement (even though the speed bump is might impressive).
At 60GHz you need line-of-sight to make a connection.. walls, buildings, trees, are all a signal killer; much more so than at 2.5/5 GHz. In general in a cluttered environment, your signal will propagate further with a longer wavelength (lower frequency, think AM/FM radio). So in short, no. It will not travel as far.
For line of sight point-to-point applications you can get very high gain from a 60GHz dish (same size dish as 2.5GHz is electrically much larger in wavelengths), though they will probably be more expensive with the tighter manufacturing tolerances required for the smaller feed parts.
Why couldn't someone grab a bunch of three-year-old desktops that are due to be junked and tie them together for a shot at the title of cheapest supercomputer?
...The applicability of randomness to AI is... spurious at best?...
Perhaps the author is referring to something like evolutionary computation. For example genetic algorithms (GAs) use random numbers extensively in selection, crossover, and mutation operations. Though I agree a good pseudo-random generator would work fine here.
Well, here's one data point. I had no trouble installing or activating TurboTax for a Windows NT guest OS in VMware (VMware Workstation 3.2.0 build-2230) on my linux box.
So I should be able to upgrade my computer and still access the software (without additional activitation)...
This topic was covered in the Cringley Bank Shot discussion.
In short: EIRP (effective isotropic radiated power) is regulated, directivity ("focusing") is significant, and the rules are different for directive and point-to-point systems. See here for an overview:
I've been lucky to have enough work [consulting for engineering design (antennas), and scientific programming] through the economic downturn. I have noticed that in the last few months the number of emails and phonecalls from head hunters/recruiters has started to creep up. Maybe 3 or 4 in January, 1 or 2 December, and 2 in the year before that. These are targeted recruiting efforts primarily for RF/Antenna engineers, from all over the country, though maybe concentrated a little more in CA.
So by this metric, the job market might be turning around. Any others notice similar trends?
Actually when using a directional antenna, the FCC says you can go over 1 watt EIRP. If the antenna is over 6dBi you have to lower the "maximum peak output power of the intentional radiator" by 1dB for every dB your antenna is over 6dBi. Further, for a fixed point to point link, this is reduced to 1dB for every 3dB your antenna is over 6dBi.
You do need to know the cable loss between your radio and your antenna. With your 24 dBi example and 2dB of loss through the cable, and 1 watt EIRP == 30 dBm:
directional antenna over 6dBi (have to reduce output power by (24-6) or 18 dB):
30dBm + 24dBi - 2dB - (24dBi - 6dBi) = 34dBm (== 2.5W EIRP)
same scenario for a fixed point-to-point link (have to reduce power by (24-6)/3 or 6 dBm):
30dBm + 24dBi - 2dB - (24dBi - 6dBi)/3 = 46dBm ( == 40W EIRP!)
Some are getting too hung up on carrying the biological metaphor too far. There is no way these systems can, in the short term, be anywhere near as complicated as that of a living system. But neither do they have do be, since the environment in which it operates is vastly less complicated than the physical world. Past success in applying simplistic biological models (GAs, etc) to limited domains seems very encouraging to me.

Campaign finance reform anyone?

You mean like the Stone SouperComputer circa 2001?http://www.extremelinux.info/stonesoup/
As they say:
performance/price = anything / 0 = infinity!

check it out and double check my math!
