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.
Re: Subtle thinking
4%!?!?! As you are mentioning names - I've used xe.com for many years (to do GBP->EUR) but I'm now using transferwise.com for my clients to pay me.
Re: Subtle thinking
25% loss? That's even worse than Paypal. And I thought that was bad enough. Those of us who live in places with modern banking systems are able to use, without any undue hassle, currency exchange brokers, who will take only about 0.5%. And I'm able to set up the transfer specified in GBP so I can get exactly what's gone on the invoice. My US customers continue to pay me via Paypal - but my USD rate takes this into account.
Lester, please tell us you managed to find some fresh milk for this, not the UHT crud that accounts for 99% of the Spanish market. If not, the whole thing stops being merely absurd and becomes farcical.
Absurd, yes; a Yorkshire Tea bag in a pot is good for two decent sized mugs of tea, four minutes brew-in-mug... urgh.

Re: Better to have no gadgets during take off
You wrote "I do not WANT to listen to the safety briefing" and also "in situations requiring it, EVERYONE will forget at least one rule". Apart from yourself, presumably. Personally I take my lead from the guys / gals up at the pointy end. Here's a typical comment from one of them: "When the safety briefing starts, I stop what I am doing, then watch and listen to the Flight Attendant's speech or videoed safety briefing, no matter how many times I've heard it or how many times I've traveled or actually flown that type of aircraft" and then a comment aimed at someone making much the same noises as you: "But I'm very impressed that you must know a hell of a lot more about aircraft than I do, after all I only flew them for 42 years".
There's numerous reasons for paying attention to the briefing EVERY time - the fact that ignoring the cabin crew is rude should be sufficient.
"my laptop / Kindle / phone does NOTHING to the plane." Actually there's numerous cases. Here's Boeing's take:
Here's a more recent incident.
It's not just mobile phones.
The crucial thing is that although the avionics *should* be shielded, and the electronic device *should* be designed not to emit large quantities of radiation, there is no *guarantee* that both these things are true. Think human nature and poor maintenance on the one hand, and cheap-as-chips far-eastern manufacturing on the other.
There's lots of reports of instruments giving out dicky readings in the cruise, due to dodgy passenger
electronics. But it's not a crucial phase of flight and the passengers would not have noticed anything wrong.
"See how long it takes to clear a RyanAir flight on landing? That's how long it's going to take in an emergency". To get type approval they need to demonstrate that they can get a full complement off in 90 seconds or less, using only half of the emergency exits. And it can be done in real life - here's one where it took two minutes to get 309 people off:
"If a plane crashes, the people who come out the other end will be random" is not true either. It's the people who head for the nearest exit-which-may-be-behind-them, and don't hang about.
"humanity's fourth attempt to build an orbital facility for humans." - I'm guessing that the first three are Skylab, Mir, and ISS, and for some reason the Salyuts and Tiangong-1 are ignored. On what basis, I do not know.
It's only 240 quid more than a B&O cordless telephone (http://www.bostpauls.co.uk/products/telephones/beocom-2/ if you don't believe me) so I hereby declare it a bargain!
Visited UUnet's Cambridge HQ once. Just off the entrance hall was the NOC. Which was arranged Houston Mission Control stylee, with big screens up front showing 24 hour news. Struck me as slightly unnecessary, and quite possibly a *bad* way of arranging staff in a NOC.

Re: Back to software...

Better engineering in the SB era?
Since BG took his hands off the tiller there have been signs that the engineering inside MS has improved. Whether SB should be given credit for this I do not know.
99% of sane people agree that Modularity Is A Good Thing.
BG famously argued "In the commercial world, it is hard to see what value such replace-ability [sic] would provide even if it could be achieved.":
Of course, BG's point is that in the commercial world, modularity just allows competitors to sell better drop-in replacements. A point that was well-learned back when DR-DOS was about to take over as the OS of choice. Gates's response to *that* was the infamous AARD code:
which created sufficient FUD that everybody bought MS-DOS to be on the safe side when installing Windows.
However by the time of IIS7, Microsoft were (and are) promoting it as "built with a completely modular architecture, on top of rich extensibility APIs. This enables developers to easily add, remove and even replace built-in IIS7 components with hand-crafted ones"!
Fast forward a few years, and I've been downloading some of the free VirtualBox VMs that Microsoft provides to allow cross-browser testing. The Windows 7 VMs weigh in at something over 4GB - this for a cut-down OS + browser, no more. But with Windows 8 they've got this down to a "mere" 2GB or so. This is still ridiculous, but it indicates that they have managed to modularise a great deal of the OS. (Equally clearly, they still have some way to go - a Firefox / Linux browser-only VM would be a small fraction of that size).
The obvious conclusion then is that post-Gates, MS have started to apply sane engineering principles to their products. But this may not be good news for MS shareholders.
Gates has, since leaving Microsoft, turned into - to my enormous surprise and slight discomfort, because I hold that his business practices held back the development of good software - something of a hero. Time will tell, but it is possible that his initiatives - and spending of hard cash - in tackling malaria in the third world will do more good than years of Western government aid.
Other software squillionaires have also done Interesting Things with the money. Let's hope that SB does.
Re: Sounds a lot like the Transit Tubes...
Or "2010: Living in the Future" by Geoffrey Hoyle, 1972:
In four or so years in Spain I never once ran out of Yorkshire tea. The real problem was finding fresh milk, when most of the supermarkets would have more varieties of UHT than bottles of the real stuff. And that was in a fairly posh bit of Catalunya. So $deity knows what it's like round Lester's neck of the woods.
(Ho yus, in a WARMED TEAPOT for dog's sake. And milk in the mug first).
Oh FFS. Mega is 10^6, always has been. If you have a 32 bit wide channel running at 10MHz, how many MB/sec does it shift? Correct, 40.
"unlicensed code's copyright rests with its author, without the coder having to do anything to claim it." is misleading, as the copyright rests with the author regardless of the licensing (unless they assign it to someone else, or the licence gives it away). As I find myself pointing out on a continual basis, the GPL (for instance) is based on a very strong *assertion* of copyright, not an abrogation of it.
Re: Lessons from Snowden
"The US would not let us have these things unless the knew there was absolutely no chance of us firing them without permission" - in actual fact the USA's nukes are controlled by PALs: http://en.wikipedia.org/wiki/Permissive_Action_Link while the UK's nukes can be launched long after everything on the surface is toast.
Re: Still don't really see the point in Trident.
"That's assuming an attack with no warning. And that a second boat isn't out on exercise with another lot of 48 warheads." My understanding is that the missiles have limited life "at sea" before they need to be brought in for (expensive) overhaul, and that therefore standard peactime practice is to run the boats with only four (IIRC) missiles aboard.
"what is our nuclear force actually for?" - maintaining a veto-wielding permanent seat on the UN Security Council. I thought everyone knew that.
Re: I never understood...
Lots. I had to do an on-site audit of some sort a few years ago which involved checking the firewall log. There was one user who would kick off every day nice and early with about 15 minutes surfing for pr0n. Maybe he'd found that he had just enough time to crack one off before anybody else got in to work.

In "Out of the Present", the documentary about (inter alia) Krikalev's 1991 stay on Mir, there's footage of him playing with a burning candle.
Re: How many articles is that on Dell now?
Same here, I'm on to my second second-hand Latitude ultralight (or whatever) laptop. They run a modern efficient OS just fine and can be picked up for a song. Often still in pristine condition, cos they've been sat in the CEO's desk drawer for three years doing nothing.
Stupid bloody distro nicknames cause more hassle than they are worth.
I get the feeling the nerds love 'em, but I am a straightforward geek and I just want a readily understandable version number. And the Ubuntu system works just great because I can tell just how old it is.
In "out of the present" Krikalev is seen playing with a lit candle.
Wikipedia notes "in American English, its name is 'zee' /ˈziː/, deriving from a late 17th century English dialectal form" and also points out that everybody else in Europe (more or less) uses a similar form. IOW the British version is the original. In this case at any rate - we've all gotten used to the idea of the opposite being true.
The American military used "zed" in their phonetic alphabet for a while:
which may have given rise to the story.
Foale, Sellers, and Patrick are all dual nationals AFAIK. Foale has an American mother so always was, the other two acquired US citizenship along the way.
Yebbut I cannot see any intrinsic reason the drone would have greater range, except some slight weight advantages. The article implied that there was.
"It has a much longer range than piloted aircraft". Intrinsically?
A quick poke of Wikipedia indicates that an EA-6B could fly this sort of mission profile.

I am all in favour of people trying to out-source to the sub-continent. It makes them all the more appreciative of a UK-based service once they've been burnt.
Re: Is Tim London based?
OK then - is your primary work tool a laptop? Mine is an IBM Model M keyboard connected to two 22 inch monitors (this is fairly modest by some developers' standards). Oh there's some sort of box that connects them together. Other important tools are a quiet room with nobody else in it, a large expanse of desktop and a chair that doesn't jiggle around constantly. I've tried writing code on a laptop on the train. I generally just give up.
As said, some retro-rockets fire just before landing. If they fail, you'll live.
If you want to go for water landing then you need to launch over water in cause of an abort - look at a map of the USSR and you'll see that puts you way out East, which wasn't practical.
The thing about Komarov turning the air blue as he came in is essentially a load of cobblers. He would have been in radio blackout until just before the parachutes were supposed to deploy.
Soyuz 18a, 1975, had a launch abort and landed on the side of a hill.
A number of capsules have had ballistic re-entries so took a while to get to but I don't think it's ever been more than a few hours:
Re: That line.
Ah. I see.
I think I only watched a couple of initial episodes - a combination of me not being that much of a telly watcher, and not living in the UK at the time. So AFAICR I only heard the line delivered the first time it was used, and (honestly) had not realised that it was a running gag.
So thanks to all for taking the time to clear that one up for me.

Re: Not surprising Apache hacked?
The way this story has been reported and commented on is completely doing my nut. If you go back to the original sucuri.net post then you will see that what they are reporting is new behaviour by Bad Peepulz ONCE THEY HAVE TAKEN CONTROL OF A SERVER. They are NOT reporting a new vulnerability in the server stack.
And it is, essentially, nothing to do with cPanel, or Apache.
Nor does there seem to be ANY evidence for SSH brute force as being the way in.
If you want root on a server (and you're not fussed which) it is a piece of piss. Scan the web looking for out-dated tim thumb implementations, or phpmyadmin installations with no root password, or whatever. Upload your shell. Now, out of all the servers you have collected, you are bound to find a few where the kernel is year or two out of date and there's a privilege escalation exploit available.
