If the decay time of each of the colour components is known, then wouldn't it be fairly straightforward to compensate for this? You could even embed a handful of sensors behind the screen the measure the output brightness for a given input signal, and compensate accordingly.
And even 1000 hours life isn't a problem if the price is right. They could make monitors/tvs so that the bulk of the electronics lasts for many years, and you simply attach a new screen every month or so - you could pick it up with your groceries.
I don't think there are any shuttles left with holds big enough to store it for launch. I seem to recall that Columbia was the only shuttle that could fit the Hubble inside.
Hmm, you've got me thinking now. I think I tried it many years ago, and that it gave the expected result. There are a couple of sites that detail this: here and here (with QT movie). But your point about the oxygen not just magically disappearing is a good one. Other sites claim that the experiment is actually a hoax, and that the rise in water level is not due to the oxygen being used up, but because the air inside the jar is heated by the candle, and then contracts when the candle goes out, drawing the water in. So I guess my example was a poor one - the candle *is* effectively filling the jar with phlogiston (or CO2) as you and the gp suggested. This site has a discussion of the experiment, and shows an experiment with steel wool that does a better job of showing the proportion of oxygen in air.
The metric system also makes it easy to calculate the weight of an amount of paper. Photocopy paper is typically 80 grams per square meter. A0 paper is exactly 1 square meter, hence 80 grams; keep halving this until you arrive at 5 grams for a sheet of A4 paper. Easy! Could be useful when trying to calculate postage, typically done by weight. Try doing that with weird-o imperial sizes...
Plus the fact that the fossil record appears to show that the extinction wasn't a quick event, but appeared to take place over 80,000 years. It's hard to see how that can have been caused by one meteor strike.
Ah yes, but if the candle had been floating in a bowl of water and then covered with a jar, the water level inside the jar would have risen as the candle burned - thus showing that the candle was indeed "consuming" the oxygen, and not saturating the jar with phogistan or whatever.
This would have been enough to prove them wrong 100 years ago. Sometimes you just need a better experiment to provide the "evidence".
I'm no physics whizz, but how about this for an explanation (just a guess on my part):
1) The discrepancy between where the sun actually is now in relation to the Earth, and the direction that gravity is currently ariving from is tiny, given that only 8 minutes have passed (small fraction of the orbital period).
2) The gravity doesn't suddenly "arrive", but is continuous, so over the course of a whole year, the discrepancy simply cancels itself out.
My sound card worked fine with Mandrake for years, then didn't work with v10. Turned out it was because the installer detected my webcam (for the first time), saw that it had a mic, and made that the default sound device. Previous versions had failed to find the webcam, hence no problems.
Maybe you have another device that could be mistaken for a soundard, and hasn't been picked up until recent distros? Just thought it might be worth mentioning. Hope you get it working.
At 40mph, 9 in 10 pedestrians struck by cars are killed. At 30mph, half are killed. At 20mph, 9 in 10 survive.
Seems like a pretty compelling statistic to me. As you state, pedestrians can wander out in front of you whatever speed you're doing, but if you end up hitting them, surely it's better to be doing 20mph than 40mph?
Yes, you could argue that maybe at 1mph, 999 out of 1000 would survive, which is even better, but obviously a practical limit has to be established, and given the dramatic change in numbers above, it would seem to lie around 20-30mph.
This applies just as strongly on an apparently deserted city road at 2am as during the day, probably more so, as you're probably even less likely to anticipate that lone pedestrian suddenly jumping out at you.
So I'd argue that the numbers above should apply to anywhere there are likely to be pedestrians, ie: urban areas. Freeways/motorways on the other hand, could reasonably be expected to be clear of pedestrians at all times, and hence subject to much higher limits.
I don't think the Russians could reach the Hubble's orbit from their launch locations. Because of their more northerly launch sites, I guess they can only reach highly inclined orbits (at least without expending a ton of fuel).
Isn't that the reason why the ISS is in such a high (steep) orbit, unlike the Hubble - and why anyone servicing Hubble can't take refuge in the ISS if anything goes wrong?
Is it just me, or has anyone else been very puzzled by the pics that NASA released of Sprit's landing site? These were supposedly taken by the Mars Orbiter Camera on the Mars Global Surveyor.
I thought that the best cameras in orbit around Mars were those on the European Mars Express, with a top resolution of 12 metres/pixel, and yet here the Spirit lander, about 2 metres aross, is spread across about 10 pixels.
Couldn't you counteract the effects of any bowing of the discs by simply flipping them over every year or so?

No, that's my point - there isn't a full fix on the Mandrake site. What there is, is a small list of tested drives, but by no means all LG drives. (And even some of those present are listed as "unknown status".)
Equally, LG released upgraded firmware for some, but not all drives.
And the procedure for resurrecting dead drives is only applicable to desktop drives - it relies on fiddling with jumpers, something that's not practical (or even possible?) with a notebook.
In short, if your drive isn't on the very small list that has been both tested and either approved, or had a patch released for it, then the issue isn't fixed at all.

The biggest problem I currently have with Mandrake is that I don't dare install it. I have a laptop with an LG CDROM drive, hence one that is potentially susceptible to the drive-killing issue that emerged with Mandrake 9.2
Mandrake do have a list of tested drives on their site, but mine (CRN-8241B) isn't there, and the closest match, the CRD-8241B, is listed as "unknown status". It seems like a few drives have been tested, some passed, some failed, and then the whole issue quietly swept under the rug.
LG tech support in the UK were totally unhelpful, first giving me the standard crap about how their drives weren't "designed for Linux" and then, when I educated them about the problem being due not to any particular OS, but to the drives' firmware, they said they'd "get back to me". I'm still waiting. They released some patches on their website, but nothing for my drive.
Meanwhile, the kernel was supposed to be updated so that it didn't send out the potentially damaging flush commands. But did this happen? I didn't hear about it anywhere prominent. Certainly not on Mandrake's site. I don't even know if the delayed public release of the Mandrake 9.2 ISOs had this fix. If so, why bother with the list of drives - if the kernel's been amended, then the issue ceases to be for all LG drives, right?
So now I'm in the situation where I don't dare install Mandrake 9.2, or any subsequent version, or even any other recent variant of Linux, for fear that it will destroy my CDROM drive. New features are all very well, but I value my hardware.
If Mandrake wants me to not stick with 9.1 forever, then they need to display a prominent notice on their website stating that CDROM-killing problem has been fixed.
Well, for all the people who have been griping about DRM, here's the chance to send a powerful message to those who insist on using it.
I've never heard of most of Warp's artists, and don't much care for the ones that I have heard. Nevertheless, I shall be buying a bunch of tracks on principle.
The only language the people at the RIAA and similar organisations understand is money. Here's a golden opportunity to spell out to them that the community will reward those that treat them fairly. If we collectively shovel a ton of money at Warp (which only requires a small contribution from each of us), then it'll be a powerful wake-up call.
Or are we going to prove to the DRM-pushers that there's no profit in being "fair" and that they were right all along?

Yeah, it only takes a slight bug in the software and this thing will break both your legs in a second.
Exoskeletons have been designed before, but no-one dared try them on for just this reason.
Yeah, and self-modifying-code was eventually abandoned because it played havoc with the then-new CPU caches and pipelines.
