"The Americans have sided with the Americans" - quite. If the claimant had been a US corporation rather than a foreign individual, I think we all know how it would have gone.
I have yet to find a web-hosting company or domain registrar that gives a stuff when informed that they have criminals using their services.
A11 landed with plenty of fuel left.

They had more than they thought - but they still thought they were good for another 40 seconds or so.

WTF? is it *that* hard to check facts before posting here? Lunokhod 1 landed in November 1970.
They're regular A4 in size and feels like 80gsm to me.

For the hard of thinking, they put this in - "[Copy-editors, check this – ed]" but for many of us, it wasn't really needed.
Re: Why does this need two Rovers?
"the engineers and scientists involved have considered these issues and come up with quite an elegant solution". Quite. It's like the sky-crane landing system for Curiosity. Seems utterly bonkers at first glance but is, of course, a logical solution.
Re: Something's Wrong
Of course there are "'wrong choices"! If they land somewhere where there is no geological evidence of liquid water, it's a balls-up.
Re: Something's Wrong
I think you miss the point. The "correctness" at stake here is not what the scientific answers are, it's choosing an interesting destination. Trying to avoid landing in the Martian equivalent of the Sahara.
The first was communion wine drunk by Buzz Aldrin just before the first moonwalk:
I disagree that it was "effectively unbreakable by the technology of the time".
The crucial flaw was that a letter could not be encoded as itself.
Even the much more sophisticated Lorentz cipher had a statistical flaw that allowed the space-age technology of Colossus to attack it.
@ Michael Hawkes - the difference between then and now is that we have the maths:
@ NoneSuch - no idea where you get your information from. "Enigma" was the name of the machine, as given to it by the manufacturers. The main problem with U-boat traffic was the introduction of the fourth rotor. I've never heard it referred to as "Oyster". Wikipedia is over there -->.
"the misguided notion that teens getting married was the norm in days gone by".
How do you figure that? There's still plenty of places on the planet where it is *still* the norm. I was staying in such a place in 2005. There was some disapproval of a wedding going on in the next village. Because the bride was twelve, IIRC. They felt that was too young. But fifteen would have been seen as perfectly normal. Eighteen probably counted as "stuck on the shelf". Meanwhile I think that boys were expected to become working adults at about sixteen, the Big Men of the village were in their late thirties, and anybody over about fifty was past it.
In short, everything happens much much sooner. Maybe it's because of the low life-expectancy alone, or perhaps the subsistence agriculture and low levels of education come into it too.
Re: They have't built a copy of teh Concord because the idea is crap
BA ran their Concorde fleet at an operating profit despite being hampered by the short range (which meant the only feasible route was across the North Atlantic) and the tiny fleet which meant no economies of scale on training, maintenance, etc.
An SST which had the range to get across the Pacific could piobably sell quite well.

Re: Try harder!
When I lived south of the Pyrenees, I'd see people out collecting snails. Also wild asparagus, when in season. Here in blighty, as a kid we'd sometimes eat boiled stinging nettles when camping, but I think it was to prove that we could, rather than for any good reason.
I liked my ex-corporate Latitude ultra-portable that I bought another - now 5.5 years old, still going strong with Linux Mint. Another year or so I expect I'll get another.

Re: a patent on a bayonet fitting?
We're commenting on the story, not the patent application. We shouldn't have to read the comments section (let alone the patent itself) to find out what the supposed novel feature is.
The cents in the article refers to Kenyan cents. 50 cents is about 0.006USD, so much the same as bitcoin.

April issue by any chance? According to WP at a depth of "100 m (330 ft) the light present from the sun is normally about 0.5% of that at the surface." At 15 times that depth it is pitch black.
Re: So why not
Boeing also won a government-funded contract to build an American SST. Before it got cancelled they'd chewed up more money than was spent developing Concorde, and they'd got as far as a plywood mockup of the cockpit (more or less). At the time of cancellation Concorde had 74 orders lined up.
Call *me* a cynic...
but I suspect the main reason that large companies are reluctant to release their source code is the amount of work involved in making them fit for public consumption, starting with removing all the comments that say things like "//Fred is an idjit, look at this crap!" and then ensuring that something embarassingly piss-poor hasn't slipped through the net.
Oh, and management thinking that "this cost us 300K to develop, therefore it is *worth* 300K"...
Re: Totally agree about WTFapp
I have a Vodafone Spain SIM and a GiffGaff UK one. When in Spain it costs roughly twice as much to send a text to a Spanish mobile - even another Vodafone - using the Spanish SIM than it does using the UK SIM.
Re: Welcome to Toyland!
It would appear to me that on the contrary, there's been a large cultural shift in MS's engineering since BG took his hand off the tiller. Whereas BG famously argued against code modularity:
by the time of IIS 7, MS were trumpeting that very same modularity and replace-ability that Gates had argued against:
Similarly you just have to look at the download size of the browser testing VMs that MS have made available to realise that they have put a lot of effort into modularising the OS.
Gates's point of course is that there's no *commercial* value in allowing other companies to release components that can replace your software - quite the opposite in fact.
Technically impressive and utterly pointless.
The reg's SPB should send them a commendation or something.

Re: Expected lifetime
Shall I try again? If your design goal is that *everything* should be still working at the end of 90 days, unless you're really quite unlucky, then your design goal is *also* that *most* of it will be working some years later. Which is what we have. It's maths.
Don't forget that (for example) one of Spirit's wheels failed back in 2006.
Yes, I have grossly simplified things. Yes, I agree it's quite an achievement.
It wasn't 'expected to last for 90 days'. It was designed to work (without significant degradation) for at *least* 90 days. That means that each component had to have a MTBF much higher than 90 days.
From that you can see that the *expected* working life *with* degradation - which is what we have now - is much much higher than 90 days.
I'll make up some numbers to illustrate the point. Let's say that the goal is 95% probability that the rover will have all of 20 major components (ten scientific instruments, ten functional systems) working at the end of the 90 days. That translates into each component having to have a 0.9974... probability of surviving 90 days. Ten years is (near enough) 40 x 90 days; 0.9974^40 = ~ 0.90. So there's still a nine in ten chance that an individual component will be working after ten years. (Ignoring wear and tear, obv). And despite starting off with a completely made-up 95% goal, this matches fairly closely what we observe: most, but not all, components still working.
Of course the other one died but I believe that was mainly a power issue.
Re: A lot of risk was taken for the Moon landings
@Vulch: I think you've taken two facts and drawn a slightly erroneous conclusion.
The "bingo call" was the point at which they had to abort OR land within the next few seconds. At the time, Apollo 11 was about 20 seconds away from the bingo call.
Subsequent analysis revealed that due to fuel sloshing around in the tanks, the low fuel level sensor (which triggered a latching indicator) was uncovered early and that the binggo countdown was started too early. The final analysis of fuel remaining indicated about 50 seconds left, which was on a par with all the other lunar landings. The lander was never designed to land with masses of fuel left.
Masses more here:

Re: Because free software is SOOOOOO secure, many eyes and all that.
The last few years I've been supporting a client who has a (relatively expensive) licence for a closed-source (and Zend-encrypted) PHP application. A few years back I noticed that the "display random image" feature was starting to get rather slow (client has more than 10^6 photos on site). With much wangling I extracted a non-encrypted version of the file from the vendor and discovered that they were using "ORDER BY RAND() LIMIT 1" in the SQL to select the photo. I rewrote it to ""SELECT COUNT(*)" to get the number of images and then used rand() in PHP to select one. So it ran about ten bazillion times faster.
I submitted my patch to the vendor.
More recently I wondered what they'd done with it so I requested an unencrypted version of the code from the latest release. And found this:
"SELECT FLOOR(RAND() * (COUNT(*) - 1)) + 1 AS offset " in the SQL
$selected = rand(0, $num_images-1); in the PHP.
To save you the hassle I've done the workings; if you have three images then the first will appear three times out of four, the second will appear one time out of four, and the third will never appear.
There's professional for you - even when *given* a working patch they can screw it up.

It's not that malaria is less "fashionable" than cancer, it's that it no longer affects the developed countries. Malaria is an entirely eradicable disease. Until not long ago both the southern United States and southern Europe were malarial. For example during the invasion of Sicily, the disease was as much of a problem for the Allied troops as enemy action.
