Even so, the architecture of the G3 didn't change AFAIK, so you would only figure a 20% decrease in latency. Maybe that's enough to go from terribly laggy to not so laggy, but I think I would want to wait until OS X.1 actually comes out and try it on an iBook before dropping lots of money on one.
A review I've read indicates that OS X system response is less than stellar on a 400 MHz G3. Maybe OS X.1 will fix that (I'm guessing that that's what people are referring to as "speed gremlins"), but meanwhile I'll wait until it comes out and find out for myself.
Incidentally, the Yellow Dog Linux review posted earlier on/. has some more real-world performance metrics than Apple marketing's Photoshop tests and show that the lower real-world system performance may be endemic to the G3/4 processors slower clock speeds. The summary is that a 500 MHz G4 is roughly equivalent to an 800 MHz Pentium III.
Profit doesn't drive stock prices. Success doesn't drive stock prices. Expectations drive stock prices, and when profit and success do not meet expectations, then the stock price will fall. Expectations are usually based on a company's predictions for that quarter, so in this case, Apple probably fell on its own sword.
On a side note, I would love an G4 Powerbook or iBook with MacOS X if a) the price weren't so high, or b) the hardware requirements didn't make the price so high. A pretty box and a pretty interface don't matter if you can't afford either. That is why, IMHO, Apple has not been able to penetrate the market.
Apple's cease-and-desist tactics have also made them less than endearing to me. Imitation is the most sincere form of flattery.
I would strongly recommend against anything using anything less than ISDN (128kbps) on the client side; I tried running a VNC client over a 28.8kbps modem connection to a server at by school (which I think had 6 T1 lines at the time) and I nearly went insane because of the high latency.

Whoever wrote the article needs to get his/her/its facts straight. The specs for the PS2, available at http://www.sc ea.com/ news/press_example.asp?ps2=ps2&ReleaseID=9, indicate that the graphics subsystem for the PS2 has 4MB of embedded DRAM. This is not necessarily the total amount of video memory that the PS2 has, and it's quite likely that a fair amount of the 32MB of system memory can be used for video as well. The embedded DRAM, however, implies that the graphics chip has 4MB of memory on the die, similar to what Bitboys Glaze3D was supposed to do (whatever happened to that, anyway?), which could lead to emormous performance increases since it can access that 4MB directly. Sorry, but I think PS2 beats DC any day...

wavelength implies spatial frequency...AC has temporal frequency (i suppose you could extrapolate a spatial frequency, but i seriously doubt that it is relevant)
if it's a laser (as the article purports), a metal mirror would probably not be a good idea. if the laser ionizes air, it will probably also turn the mirror into plasma, since most metal coatings have a low damage threshhold.
Can't agree more...I just upgraded by K6 233 to a dual Pentium II 333 for hundreds of dollars less than it would cost to upgrade to a Pentium III...I suppose I might be missing the benefits of SSE (after all, you do need a Pentium III to surf the web and type letters...), but when I run NT (and hopefully Linux, if I can ever successfully compile SMP support into my kernel), my box can eat Pentium III's for lunch...
On a related sidenote, NAV gets really obnoxious when you try to visit the Zero-Knowledge page about the exploit. It harrassed me at least 3 times before letting me view the page. I suppose it would be useful if it were malicious, but in this case, I think it's just really stupid and really annoying...
Uhh, i think you should visit the page, because it is quite apparent that you haven't. The claim is that it will extract the PID even if you've disabled it through software or BIOS. I say claim because I can't exactly try it myself: I running dual Pentium II's, which is a lot cheaper than a Pentium III. I would also extrapolate that the ability to extract the PID is not limited to ActiveX; I imagine that one could write a trojan that could do the same thing.
Anyway, did AT&T sell it or license it? If they sold it, that would mean that Digital, IBM, Sun, HP, etc., have to pay royalties to SCO; no wonder they're so interested in Linux...
Slashdot Mirror
Are all servers set to UTC?
Apparently that link has been a moving target, although it looks like Microsoft has settled on the location you've posted...for now.
Why? No one who reads /. uses Microsoft products...oh wait...nevermind...
Microsoft, in their infinite wisdom, seems to have moved the patch so that people can't download it. Anyone know where it is now?

This research was published in the 19 October issue of Nature.
Vreeland, R. H., Rosenzweig, W. D. & Powers, D. W. Nature 407, 897?00 (2000).
Incidentally, the reason the story may have been pulled is because Nature has a press embargo on research that is in the review process.

it'll fry your retina pretty good, too. UV lasers are what they use for radial keratotomy (sp?) and reattaching detached retinas.
if it's a laser (as the article purports), a metal mirror would probably not be a good idea. if the laser ionizes air, it will probably also turn the mirror into plasma, since most metal coatings have a low damage threshhold.
Uh, someone score this out of the default threshhold...this is in really bad taste, regardless of your perspective on the issue...
