the only constant thing is still c^Hgeometry.
as I understood it
No, the photon doesn't have any expiry date on it just because it came from the soup(*). Also, energy is conserved because the mirror's momentum is sapped by an amount equal to and opposite of the energy of the created photon. Or, since the mirror isn't physical in this case, the creation of photons means that the power supply for the apparatus has to pump more joules in in order to achieve the same acceleration curve.
(* Although I'm sure the Thomas Edison Electric Light Company (aka General Electric) would love to be able to sell photons with a "use-by" date, a quick search shows that photons are thought to have an infinite half-life)
where to buy FLAC
For the few people who asked this question (and couldn't be bothered to do a web search themselves):
This isn't a complete list. There are quite a few independent labels and some bands (groups) that offer flac downloads. You'd have to go to their websites to check for yourself. There seems to be a lot more electronic artists whose catalogue is available in Flac format as compared with more mainstream/pop artists. Check out bleep.com for a pretty decent selection in this genre. FLAC costs more than MP3, but that's totally understandable.
[FLAC] Lossless? Yes.
The hint is in the acronym--'L' for .. (you guessed it) "Lossless".
The flac program has variable setting for how hard it should try to compress the file. It is not a "quality" setting.
Wavpack, on the other hand, does have a hybrid lossy/lossless mode, so seeing a .wv file doesn't necessarily mean lossless there--you'd need the corresponding "correction" file (.wvc) to get back the original file losslessly if hybrid mode was used. I'm a big fan of flac, but wavpack's hybrid mode could make it quite attractive to music vendors since they'd only have to create one master set of lossy/lossless (.wv/.wvc) files for each track and then sell each separately. It would also make it very suitable for mobile players, since you probably don't need the full lossless file for those devices and space is at a premium. Having the data split into lossy/lossless parts also makes it a lot easier for syncing since you don't need to do any transcoding--just copy the smaller .wv file across (assuming your device supports wavpack, of course).
Oh, and "mild DRM"? You're having a laugh there, right?
"war on numeracy?"
Judging by other wars in their "War on X" range, it would be "War on Numbers", not numeracy. X has to be something that, technically speaking, you can't fight against.
You say that ALAC is less processor-intensive than FLAC. However, the hydrogenaudio.org wiki page[*] comparing lossless formats rates FLAC decoding as "very fast" whereas ALAC only gets a "fast" rating. If the best advantage you can come up with is actually not in ALAC's favour at all, then why would I want to use ALAC over FLAC? Or do you have some other evidence to support the claim that ALAC is less processor-intensive?
Something that wasn't mentioned in the article was whether Apple claims to have any patents covering ALAC. I'd be very interested in finding out whether they do. I find it quite hard to believe that there aren't some strings attached to this freeing up of the format. TBH, though, even if they'd released it under something like GPL3 with a "no patent" slant, I doubt there'd be any incentive for the majority of people to switch from FLAC to ALAC...
though not specifically to do with thermal imaging.. is to look at regular keypad-based locks on doors to look for buttons that are more worn down than the others. Based on the assumption that they don't bother changing the code, of course, which would level out the wear patterns and make them useless in trying to brute-force the code.
A grammar checker should find fault with "rioters should loose their benefits" on the grounds that "the sentence no verb". (Yes, I know "should" counts, but the embedded part describing what they should do is missing a verb). Change it to "loosen" or "let loose" and it does become grammatically sound, though obviously that's the wrong fix.
It's been a while since I used a grammar checker, and I don't have one installed on my machine right now so I can't check this, but I suspect that most checkers would flag "loose" to the user as being a frequently-confused word.
In fact, this online grammar checker (the first one I found in a web search) definitely flags the error: http://www.spellchecker.net/grammar/
sorry if I've offended
I'm not insensitive to the girl or her family. I'm really just dumbfounded by the sheer bizarreness of the story. Still, I guess the downvotes were to be expected.
it all sounds like a cross between
Battle Royale and Saw. Anyway. and forgive my glibness, it sounded, on the whole, a lot more like attention seeking behaviour than a serious threat.
surely it could avoid this fate

sorry to respond to my own post, but..
I meant that burokksu would be a more natural transliteration for "blocks". "ボロックス" is definitely pronounced "bollocks" (or at least somewhere between "bollocks" and "borrocks").
Surely ブロックス (burokkusu) would be a more natural transliteration? Like ブログ (burogu) for 'Blog'.
I was thinking on reading the article that if a helium balloon is too costly, why not make a hydrogen one? It's not like it's going to matter if it blows up. I reckon (in a totally non-numerical sense) a lacquered paper balloon could retain enough hydrogen to lift it quite a distance. You wouldn't necessarily need any expensive pressurised hydrogen tanks. If you had some sort of chemical or electrolytic reaction to produce the hydrogen and a way of sequestering at least some of the oxygen (in plain electrolysis of water) you could probably produce and trap enough of it in the balloon to get you to the desired height.
Once at a high enough altitude, you could then, hopefully, use a more conventional rocket to carry the payload beyond the atmosphere. Aiming would be tricky, but if you suspend the rocket below the hydrogen-producing part and have a combination of barometer (altimeter) and accelerometer readings (maybe combined with a timer) you can use a bit of fuzzy logic to determine the best time to engage the rocket stage while it's more or less pointing in the right direction and still retaining at least some kinetic energy from the balloon contraption.
Alternatively, I read that the most recent volcanic eruption in Iceland threw ash and other stuff up to a height of over 12 miles. That's still a long way to go to get to LEO and obviously reliant on the occurrence of a relatively rare event, not to mention needing to design a secondary rocket which could survive the initial lift-off, but at least it reduces the cost of the primary ballistic system to zero.

I can understand outsourcing your ad links
But surely a web server who wants geolocation data can just get it from their access logs, which store IP addresses. Shouldn't be too hard to collate those data with referring page information on the advertiser's site, or simply capture the click on the server and use a redirect to actual advertiser. Or is disintermediating Google just too costly/troublesome for most?
we've all been softened up for this already
One fine day the Reg will ask if you want a platinum cookie, and most people will jump at the chance since they know what a wondrous thing it is. Most people won't read the fine print, obviously.
You can use the same techniques used in washi paper making, making them less absorbent. Though my guess is that if you're printing something that's only microns thick paper might be too bumpy. So I guess they print on glass or plastic?
If I understand this correctly, there's no reason to assume linux is any more secure here.
Let's start with there being an infected MBR and this gets run before the operating system. In the old days of boot sector/MBR viruses, the virus would allocate some memory for itself using the BIOS, then patch in some entries into the interrupt table, say int 13h, which does low-level disk I/O. The classic sneaky viruses would intercept calls to access the disk and if it was already infected it would return a "cleaned" version so that virus scanners couldn't detect it (hence the need to boot off clean floppies if you wanted to be sure the scanner was working). If the disk (or file) wasn't infected, the virus would usually take that opportunity to do so at the time it's being accessed. The DIR-II virus worked quite like that.
Fast forward to more modern OSs and some things have changed, but not everything. In general, once linux has booted up, it doesn't use the BIOS for anything any more, so even if an MBR virus did manage to install itself before the OS, it would be stranded since int 13H would never get called and the virus would never execute. Apparently (from a quick search) windows still does use the BIOS for disk I/O, so maybe you'd chalk that up as a "linux is better" point. Actually, it's no reason to celebrate just yet... because Linux does use the BIOS at one key stage--when it's booting up, ie loading the kernel.
So actually, if you wrote an MBR virus that was aware of modern operating systems, you could actually hook into the BIOS entries for disk access and when Linux is booting the kernel you return an infected version on the fly. So in theory at least, neither OS is better on this score.
copy con com1
Hmmm... that brings me back to the days of using an RS232 cable to transfer files between (PC) computers. Back before network cards (ether or token ring) were commonplace. I can't remember the name of the program that was used but it used a very similar method to what's described in the article. The sending side would run the transfer software and on the receiving side you'd start by typing in "copy com1 con" which basically copies input (ascii) from the serial port to the keyboard. The sending side would then "type" in a small bootstrap program which would be saved on the target computer. That bootstrap program would then copy over the rest of the program so you could get a nicer interface to show files in progress, transfer checksums so that you could detect transmission errors and the like.
The best part of the scheme was that you'd end up with a working copy of the transfer program on the target computer, so you could start the transfer from that machine to another machine later. Looking back, I suppose it's kind of funny that we were all using a kind of worm program for a useful purpose. I'd love to remember what it was called. Might have been something generic like "PC Link"?
Of course, this custom mouse does away with the need for the user to type "copy com1 con" on the receiving side, since it already is the keyboard.
Or just make sure you use the

I think they were drinking, so if they were drinking Budweiser it'd be double-concentrated (the pee, not the "beer").
(incidentally, oh noes... I've had American Pie running around in my brain since I woke up... this just makes it worse)
clear case of contempt?
So you and others have been saying in the comments here. However, read the article and you'll see that she presented herself at the appropriate time, but was not allowed in. Hence the catch-22 situation described in the article. And the sub-head. Seriously...
same flight as McKinnon?
Are you mad? With two super-terrorists in the same plane, you're just asking for trouble. Have you never seen Con-Air?
the pointing finger
was broken, and having been broken, pointed no more.
the real risk here
is that a terrorist can get an easy lock with their smug-seeking missiles.
Simple in emacs:
C-1 M-x show-paren-mode
The show-paren mode is usually turned on by default for languages that emacs knows about--and it knows how to handle many languages.
Most programmers' editors do something similar. Plus most of them have intelligent tab handling to bring you to an appropriate indent level and will also align closing brackets of all kinds with the corresponding open bracket or whatever block marker the language uses. Personally, I prefer brackets over verbose if / endif style languages since you can see an awful lot more code on screen at once and it makes it actually easier to follow what the code is doing without having to scroll up and down.
This doesn't work syntactically. There aren't any rules for deciding on the relative precedence of ++C and C++. The fact that the language doesn't include such a rule is due to both (++C) and (C++) not being lvalues so they can't be pre/post-incremented and the question of relative precedence doesn't arise. The related C++++ doesn't work either, for the same reason. You could call it (C+=2,C-2) but it's hardly a very catchy name.
Also a rather amusing song by The Lewis Duckworth Method:
It was jiggery pokery, trickery, chokery,
how did he open me up,
Out for a buggering duck,
What a delivery,
I might as well have been,
holding a concert bassoon,
Jiggery Pokery who was this nobody
making me look a buffoon
