So we know the plaintext?
I thought known plaintext attacks were considerably easier than unknown. Doesn't that actually make the Linux version less secure? And while the Windows version doesn't suffer the known plaintext vulnerability, the "random" plaintext is not yet verified. So we're not happy either way yet.

I don't even see them unless ... they misbehave
Don't! You'll give them ideas!
Have my up-vote! A couple of points:
I have heard that in the UK regulations or laws were made to stop "unreasonable" roaming charges. That was quite a few years ago. I presume that similar regs. or laws are not present in every country, and that, even where they are, the telcos find ways of gouging customers, and it all slides downhill for Joe Public. It seems that democracies don't have the will and money to aggressively update regulations, and a benevolent dictator is as likely as a benevolent telco. I wonder if, when Tony Blair said he was “intensely relaxed about people getting filthy rich”, he was aware that they could only get rich at the expense of their fellow countrymen, and that this was a betrayal of the Labour Party.
I reckon that the rich have exploited the poor everywhere forever, with some minor variation on the scale of say 100 years. I must say that advertising has become so prevalent, sophisticated and insidious that it is difficult to withstand it. To your comfort, whereas my children rejected my oft expressed cynicism about advertising when they were teenagers, they now seem better protected than some people.
The same timescale applies to obscene content. Think gladiators, temple prostitutes, etc etc
Re: Space "Scientists"
Anyone remember "Victory Unintentional" by Asimov?
Our website was hijacked for a small period of time, during which attackers redirected our website to another IP address. We can confirm that no user data was lost or compromised.
If the fake website managed to catch any username/password data, then those accounts are compromised and the owners of the real website would not know, so they cannot confirm any such thing.
Did I miss something?
What an obscure format to describe a change in reliability. Perhaps he meant to say that the failure rate of tapes has been reduced by a factor of eight? And then is the failure taken as " a whole tape cartridge becoming unusable" or "a bit (or byte) was read back wrongly", and is the latter before or after error correction?
I can't see that it was really known three years ago. Translating the last few lines of the Russian post gives:
And there is an interesting line in the elf-binaries Web server:
(Try reading it backwards)
To sum up - friends, colleagues, tell me where to find the list of users / passwords?
So it looks as though he had not followed up the lead, at least not publicly ;-)
Re: My girlfriend at the time
When I described latex to my friend who was having so much trouble with MS Word, she said "oh: that sounds complicated" (1). I'm heartened that you can mention a non-techie user who got on with it just fine.
(1) Compared to *what*?! Rant ... rant ... rant
Re: And this is news, how?
After being forced to use MS Word for what feels like a life sentence, I have come to the considered opinion that, if you have to use it for more than half an hour, it is the wrong tool for the job. I have a mental map of MS Word's features, and most of it is marked "here be dragons".
Perhaps I gave up on OpenOffice etc. too soon, being so disappointed with MS Word, but it was not the most productive tool for me.
I'd happily dive down the vi-svn-diff-latex-postscript route, but other posters have hinted at what normal people are supposed to do ;->
I recently spoke to a non-techie user who was writing her thesis using MS Word, and she lives in fear of the department's mandatory review of her document with the man called the Publishing Expert who is the only person in the department who knows how to adjust the formatting without losing several paragraphs. And there was me cherishing the thought that universities used Latex!
Re: Noise pollution - CAPD
From good old wikpedia:
APD [Audio Processing Deficiency] is a difficult disorder to detect and diagnose. The subjective symptoms that lead to an evaluation for APD include an intermittent inability to process verbal information, leading the person to guess to fill in the processing gaps. There may also be disproportionate problems with decoding speech in noisy environments.
I don't think I'm Aspergers, but I do remember one acutely embarrassing situation where I asked someone the name of some guitarist repeatedly, 6 times actually, and still had no idea what he said at all.
Re: Why GPS to work out where the sun is?
Actually, the article doesn't say "GPS". The wording makes me think of compass and clock, but actually their description is compatible with your excellent suggestion. Your suggestion works easily for single axis tilt, and two rings of LDRs at right angles would be accurate enough for double axis tilt.
Farcebook, Facebork, ...
Wow. That went spectacularly wrong.
The view inside the LHC...

Tupperware? What's that got to do with it?
They might as well say that there's methane in the atmosphere, and methane is a notable constituent of farts.
And I was taught to write "propene" as the new approved name, and that was over 30 years ago.
Rain drops keep falling on my head

Data vs Meta Data
Did anyone else notice that the leak said that meta data was stored, but the NSA denied listening to phone conversations and reading emails, which is data not meta data. I interpret the leak as saying that the NSA stores "who called whom and when" and "who emailed whom and when and possibly the email subject".
In which case, the NSA are not actually lying. Just to make it clear, I therefore despise them.
I thought I'd look up the cost of setting up a DAB transmitter, and found this:
So it's probably comparable to an FM transmitter. (Perhaps twice as expensive rather than 100 times as expensive?)
I wonder if Ofcom would smile on me if I tried to transmit DAB...
Re: "Oops. Did hitting that mess something up for you?"
Reset button was usually right there on the chassis.
I remember a MAC with the reset button at "mouse height". The number of people in my lab who accidentally ran their mouse into it. Disbelief, cold sweat, realisation, anger, and finally the search for something like a rubber (1) to sit in front of it.

Re: As useful and as relevant as a fig leaf
It's a matter of timing. A fig leaf after the event is not nearly as good as a fig leaf when you need it.
Re: Lovely Low Quality
I'm pleased someone loves their DAB radio, because it is a very interesting technology. There is potential for excellent sound quality coupled with information services, and I once sent streaming video and files over it.
We all know that any deficiencies in the DAB experience are due to
a) Allocating too little bandwidth, so as to squeeze in more channels at the expense of sound quality
b) Not even bothering to transmit interesting text info, like full details of the track playing
c) Poor user interfaces, as if someone has re-invented the wheel and tried a square version this time
The parallels with my lovely computer hardware and some of the software available for it will make all of us wince.
I know I would expect service where it is promised, so I sympathise with anyone dismayed by this, but perhaps it is just as well to reflect on the inherently insecure aspects of many forms of communication.
The fault tolerance, even fault correction, is a very important achievement. I wonder if this could be used to make e.g. silicon transistors smaller?
Re: Parasitic radio power
Yes. Another depressing fact is that when BT did not allow their customers to connect anything unapproved to the phone line, the charge would be "stealing electrical power". Clearly, there is no information transferred without power transfer, so I would be prosecuted for stealing microwatts.
Re: It worries me
I have just checked a "modern" microwave with a bent LED, and the LED did not light that I could see. Perhaps I am worrying too much. Like people who worry about being 50 yards from a mobile phone base station but will happily put a mobile to their head, and I should hate to be quite so squeamish. I still refuse to put my face up to the microwave, because that's a rotten way to test for leaks. Reminds me of "do not look into laser with remaining good eye".
But I disagree with several things you said. Perhaps I shouldn't bite, but my pride is injured ;-)
Modern microwaves have similar or more power than the ones I was reporting, i.e. typically 800W rather than 500W.
Microwaves heat food the same way now as then, so the things making food taste better will be a) better controlled cooking times and b) recipes formulated to withstand microwave cooking.
A narrower output would have just as much effect on a LED.
Modern microwaves have a similarly crude generator, with mains-plus-harmonics going through a step-up transformer and then to the magnetron. So I see no reason for a narrower output. (Then again, it is possible for very simple snubbers to limit the frequencies of the magnetron drive: we should measure it sometime.) Besides, if they are better shielded, there is less worry about the spectrum of the output.
The sheet steel case is not the only shielding. There is also the mesh in the glass window and springy bits of metal round the door to help close up gaps.
The shielding is not minimal, and is definitely needed. I know what 50W feels like (hand in front of TWT+horn), so 10dB shielding is not enough.
But I agree with other points. E.g. the sheet steel need not be so thick for shielding, but rather for mechanical strength. Compare with the mesh in the glass window.
Energy saving probably not as applicable as hoped
The idea that you can use energy that would otherwise be wasted must be tempered with concepts like "near field", "waveguide below cutoff", "evanescent", etc. Basically, if there is no way for some of the electromagnetic field to transfer energy, it won't; not tapping into an energy source does not always mean it is going to leak away.
Re: It worries me
And worry you should, at short distances. Whereas microwave ovens may well be better shielded now than when they first became popular, I remember in the past we could get an LED and bend its legs so as to make a suitable sized dipole, and the LED would light when placed near a uW oven. I never let anyone put their face to the glass: you don't really need to, and why risk it?!
Thank you: I was looking for some consideration of the implication that life must have started on merely another planet.
Nice idea, but...
I remember an idealistic and misguided attempt to stop people writing on the walls in the boys toilets. I put up a sheet of paper for people to use, so that the caretaker need not repaint the walls so often. Someone wrote on the wall nearby "Damn! Missed!"
I think the literary examples quoted above would be inspiring for some. Others would benefit from being shown examples of litotes etc. etc. But there will always be those who kick against the goads.
Doesn't Big Business Do Software Development Any More?
We will never get anywhere if all developers merely nudge existing products towards what they hope will sell.
And the principles are so basic!
So Microsoft had a working version of Word that ran on Win 3.1? I bet they had a modest set of features rather than bloated software, had not yet added smooth scrolling (or other unnecessary resource consuming features), and actually developed the software so that it used resources sparingly. That way, the software runs at reasonable speed, crashes less, coexists with other software, and provides most of the features people want.
The other thing we need is new interfaces that suit the hardware. Doesn't anyone look into better ways of coping with (size of finger tip)/(size of screen) > (size of mouse cursor)/(size of screen)? How about dasher (http://www.inference.phy.cam.ac.uk/dasher/)? Or adapt that to be a qwerty keyboard that expands in the area where your finger is, or where it expects the next character? (I really must stop trying to develop ideas while posting El-Reg comments.)
And fancy not supporting a plug-in keyboard. I had an Ericson mobile that did that 20 years ago.
No wonder Free Software has grown up: I couldn't write it all myself. But it's such an opportunity for companies like Microsoft!
I can see there is no let-up for the vigilant. I might have used VMs to test various new updates, but, for VM software itself, I'd need to have a KVM installation to test VMWare and vice versa. Sigh.
Re: 3.8v Battery???
Surely Li batteries can be expected to measure from 2.2V to 4.2V when they hold sufficient charge to be usable. This is viable because of sufficiently advanced switch-mode PSUs, where a wide range of input voltage can be accommodated efficiently, and where <2.2V operation is avoided lest we kill the battery. So I recommend labeling them as "3V", i.e. only one significant figure rather than two, and, even then, 3 to 4-delta is only half of the range.
So 3.6, 3.7 or 3.8: there is no significance. Perhaps it is driven by marketing: queue the 4.2V spec!
Would I steal an iPhone?
I wouldn't go for an iPhone because it doesn't really invite me to take it apart and see how it works, play with it, and use it for something completely different. Of course, I'd never steal anything (1), but I don't have the inclination to start with iPhones.
Do you think the thief took the 5S just to spite the fanbois? That would be another emotion for which I have no sympathy: I wish Apple users all the best, hopefully as they enjoy shiny new technology which largely works as expected.
Sorry: I sympathise with the poor chap who had his phone stolen. We have to live with finite risk in all areas, and it's not pleasant when we take a hit.
(1) What, *never* ?! Well, hardly ever..

What makes a good engineer?
The lab technician at Cambridge told me that Dolby was "thick as two short planks", but was a success because he surrounded himself with clever people. I think that is a bit harsh, but what he had observed was mediocre marks for write-ups of practicals, and he generally predicted people's exam based on such.
So Dolby must have been a visionary to carry it all forward, and the Dolby system must have been good enough to impress somebody (yes, I know you can pick that one apart).
Personally, I turned off Dolby on playback and turned down the treble a bit if required. I did experiment with a cassette recorder with Dolby C, and I used fairly good quality tapes (TDK SA), but it was a profound relief when digital recording for the masses arrived.

Re: that machines are probably better at doing
There's also several Philip K Dick stories to refer to:-
The Defenders - robots on the surface, pretending that the war is still raging, keep humans underground so that they do not engage in actual war
Second Variety - what we might now call "drones" are built to self-replicate and kill enemy soldiers, but develop so effectively that they kill both sides, and are so deceptive that they manage to find out where the last remnant of mankind is hiding on the moon
Probably more that I have forgotten...
Re: Never knew that
Because I know the passwords are there, I have fallen into the error of thinking that everyone else knows too. If you, experienced as you are, did not know, then that helps me to see that it is more serious. But, of course, you probably treat an unlocked screen as a liability, so you are safe by other means. Therefore I recommend educating the masses to be much, much more wary.
C.f. the GP in the 1980's who thought that sending patient details down a phone line with a modem was secure because it was digital. He never thought that because the intended recipient could read it then so could any eavesdropper!

@dkjd Re: Thank god I bought VHS: Single-Use Media, Anyone?
I have many books, tapes and DVDs that I have used once and then kept for sentimental reasons: fine. On the other hand, seeing that I re-use these items so rarely, perhaps I would be better served by cheap single-use media. Make it easy to pay, easy to obtain, easy to use, plays on anything, no DRM, cheap enough to put TPB out of business. That would be a disruptive business model!
And may I hope that the artists, publishers and suppliers would all get their cut?
If storage becomes cheap enough and convenient enough that old formats can be amassed and traded by those not associated with the creators, rather than invoking copyright to limit pirating, let the newer formats, which inevitably use up the bandwidth available for high-res content, still be the most desirable media, not precluded by price or DRM.
According to this model, we would want copyright limited to say 5 years or even less, so that, when the legitimate publishers etc. find that they cannot make money out of older works, we can still obtain anything from the amassed old formats.
All we need now is for people to behave sensibly and fairly. Sounds like a promising Dickens novel. Sigh.
Re: wtf wtf wtf
everyone is competing for the most repulsive idea imaginable Quite.
It makes me consider rejecting any food I didn't process myself. Sorry: that could have been worded better.
But the issue is overriding the human instinct where we pick out the bits we don't like the look of. I expect that there is a lot of self preservation in this instinct, but it's not 100% reliable (examples, anyone?), and if we avoid Bad Science we should be able to improve our health.
So now it all turns into trusting scientists, politicians and the food industry, because I haven't the stomach for butchering, or biology, or, on a bad day, even cutting out the squidgy bits from vegetables.
I remember when our daughter was very young we had only just managed to coax her to start her dinner when our son said "She would have been all right, but she saw one of the carrots moving".
Paris, because she knows about squidgy bits versus pleasure.
