Cree just announced an LED with an efficiency of 131 luments per watt (compared to incandescent light bulbs at 10 to 20 lumens per watt range, and compact fluorescent lamps range from 50 to 60 lumens per watt).
So they are coming. Then again, Cree seems to have a history of "science by press release", where they announce these amazing specs, then never bring the product to market.
Also, you can't find CF lamps with a replaceable bulb
I'm annoyed by this as well. Although the wikipedia article on the subject says the ballasts often fail first anyway.
I've been considering getting some of the circular tubes, they have an Edison base, but the tubes are replaceable. Obviously these won't fit in a lot of spaces, though.
the problem with non-traditional lightbulbs isn't that they're weak -- it's that they cast a harsh light.
This is a common perception - yet the reality is that CFL output is much closer to sunlight (5500K, although this varies depending on location and time of day). I think the problem is that people have been using incandescent lights so long they have become conditioned to expect poor quality yellow light, so white light seems harsh by comparison. Do a google search for "color rendering index" (CRI), which is a way of measuring how well a light source allows colors to be distinguished. You'll find that no incand. bulb, even exotic and expensive "full spectrum" bulbs, can hold a candle to even the cheapest fluorescent.
The Iowa Electronic Markets is one of the oldest futures markets of this nature. It's real money (though you can only 'invest' $50), and completely legal. Most of the markets are related to major elections, but there are a few others (like fed. policy and MSFT price). I'm been an active trader since the 2000 election and it's been pretty interesting.

In the first article on this deal that slashdot linked, Intel admitted the limit was arbitrary, and the result of a marketing deal:
But there are no specific instructions in Intel's current Pentium D or Core Duo chips that enhance the performance of VoIP applications, an Intel representative said. Skype is using an operation called "Get CPU ID" to identify the type of processor running on the PC. The Skype software has been preset to only accept Intel's chips as having the performance necessary to host conference calls of more than five people, the representative said.
The reason why no one writes viruses for Apple is most likely because people like Apple and want them to succeed.
Considering that the main incentive for virus writers these days seems to be economic (profitable criminal activity such as spamming, phishing, DDOS blackmail, identity fraud), it seems unlikely to me that these criminals care if Apple succeeds. More likely, the profit motive isn't there, probably a result the combination of greater security on OSX, and smaller installed base.
Planck's constant = 6.626068 × 10-34 m2 kg/S. It's that 10**-34 that makes it difficult for low-energy electromagetism like wireless transmissions to interact with chemical reactions
Not sure I understand the relevancy of Plank's constant (although I'll admit I barely passed my EM Theory class). Are you saying that because an individual photon has a very small amount of energy that photons cannot interact with chemical reactions? What about gamma radiation, which has long been understood to be bad for living things (bad when exposed indiscriminantly, yes there are medical uses for it as well)?
There is evidence that microwaves can cleave DNA, from which you might infer in could be mutagenic, hence carcinogenic: non-thermal DNA breakage by mobile-phone radiation. Search pubmed for microwaves and you'll find lots of interesting results.
The quote in your article summary 'more effective, 24-hour propaganda machine' looks like it's quoting Rummy, but in fact it looks like those are the words of the BBC author. I checked a few different news sources, and could not find Rumsfeld directly quoted anywhere using the word 'propaganda'.
Not that propaganda wouldn't be a good idea. Something like the spiritual arms control suggested by Richard Dawkins might be useful.
"departments paying journalists to endorse their positions, it begs the question, how much more can they possibly do?"
Begging the question does not mean what you think (despite the common misuse). Use "raises the question" in this context.
I have never run OSX but generally, software is licensed, not sold. You did not "buy" the software, you bought a license to use it under the seller's terms.
In the U.S. at least, this is not necessarily so. There is case law supporting the notion that sale of software is considered a sale under the Uniform Commercial Code. See Step-Saver Data Systems, Inc. v. Wyse Technology for the most well-known example.
And if it is in fact a sale, then the copy is yours to do whatever you wish with it (including modifications such as stripping out the EULA dialog, and making fair use copies).
Sec. 117. - Limitations on exclusive rights: Computer programs
(a) Making of Additional Copy or Adaptation by Owner of Copy. -
Notwithstanding the provisions of section 106, it is not an infringement for the owner of a copy of a computer program to make or authorize the making of another copy or adaptation of that computer program provided:
(1)
that such a new copy or adaptation is created as an essential step in the utilization of the computer program in conjunction with a machine and that it is used in no other manner, or
(2)
that such new copy or adaptation is for archival purposes only and that all archival copies are destroyed in the event that continued possession of the computer program should cease to be rightful.
You never lawfully obtain a copy of Mac OS X to do with whatever you wish..... You may dislike the fact that you never lawfully obtained a copy of Mac OS X to do with whatever you wish, but there is no ambiguity about your situation as far as the law is concerned

The boy scouts looked at how much litigation has taken away from really good youth organizations and realized, sending kids camping with a gay guy as their chaparone is just as much a liability
No. The problem is not one of liability, but rather a few fat, old, white, assholes in Texas (BSA HQ) who like you equate queers with pedophiles. I have been in scouting for 20 years, and most of us are not homophobes.
Linus signs code with private key, to allow users to verify that it is an "authentic" kernel.org version
I want Linus' private key
I build trivial embedded device, that only runs kernel if signed by linus
Linus must now disclose his key, since the software "won't run without it"
The problem with this part of the GPLv3 is that signed-code requirements are hardware dependent. If you say that the requirement only applies if the only hardware platform available requires signed code, then a Tivo-like company could easily dodge this requirement altogether. i.e., by saying that modified GPL tivo code can be run on a non-tivo generic PC, without a signature.
Not likely to work, imagine 50,000 tickets, and a 16-byte bar code. That gives a
50000/2**128 chance to guess one at random. If you could scan a hundred codes per second, it would take
2**128/50000/3600/24/365/100 = 2.2e+24 years to get one right, which is about 160 trillion times the age of the known universe.

I work for a university, and I have been able to get warranty replacements from Western Digital by faxing them a letter on company letterhead, explaining the reasons why we can't return the drive, and attaching a picture of the drive's top plate.
We then let the geeks have fun destroying the disks.;) But the parent is absolutely right. If you can't get replacements this way, you'll just have to deal with the cost of replacing them yourself.
CherryOS is a commercial product actively encouraging its users to break Apple's Mac OS X license agreement. And yes, this license agreement is binding: that's why no one makes clones. (And no, Apple "ROMs" are no longer required. Haven't been for ages.)
Is the OS X EULA really the only thing stopping clone manufacturers? What's to stop some Taiwanese vendor from selling a cheap beige-box PowerPC with Yellow Dog Linux (or Darwin for that matter), whith a big warning: "Danger - under no circumstances should you install MacOS X!"
I'm aware that Macs no longer rely on ROMs, but it seems there must be some other factor stopping potential clone makers.
Further, I think the legality of bypassing a EULA is untested (for example, using Interface Builder to swap the 'Accept' and 'Decline' buttons). At least in the United States, you do not need a license to use software, only to make copies. Section 117 of copyright laws says:

Essentially, loading the software onto a disk and into memory isn't considered infringement (even though it's technically a copy). This is why you can use GPL'd software (or any other software that you legally obtained, for that matter) without accepting the license.
Not that I'm eager to see Mac clones back on the market... it nearly killed them last time.
RFC1323 specifies a resolution down to 1ms. Below that, the proposed fingerprinting method can't tell anything.
It may be possible to get much higher resolution measurements by averaging lots of samples. It's possible to measure the speed of light using 'ping' this way.

I believe the technique you describe is known as a "tarpit"... some SMTP servers implement it.
What you are describing sounds like a known plaintext attack. No encryption algorithm worth it's salt is vulnerable to this type of attack.
My favorite search engines, through the ages:
- Archie
- Veronica
- WebCrawler
- Alta Vista
- HotBot
- Google
There will be others, though hopefully not MSN!The reason why no one writes viruses for Apple is most likely because people like Apple and want them to succeed.

70MPG good enough?
Parent is lying like a fisherman, if you follow the link the Jetta gets 30 highway mpg (gasoline version), or 41 for the diesel.
OK, that makes sense. I think what I was overlooking was the codes "necessary .... in the recommended or principal context of use".

oops, you are right, I don't know why I was thinking 10**6.
