Re: Fighter Aircraft Simulator
The hardware must have improved by as much as 3 orders of magnitude since then...
Re: Collective Delusion.
Atheism is a bona fide religion.
Doing more research would suggest "cupona"(am) (as I am still quite liking the accusative). But "taberna" is still more universally understood and isn't actually wrong. After all "tavern", "taverna" etc still exist.

Like the 'ad astra et ad taverna' but it's clearly in the wrong order and not very latin really. How about "ad tabernam ad astra"?
It doesn't have to be a root user especially, just a directory in which one has sufficient rights to create a file AND (rather more importantly) some dumb person (with sufficient rights) who is likely not to notice a a file called '-rf *' or whatever before doing some wildcard rm anyway.
The crucial thing is, of course, that the perp will have logged in with a username and left his (bound to be a bloke) fingerprints all over it, username, creation time etc etc. Any sysadmin worthy of the name is likely to notice these peculiarly named files and is going to investigate.
History is sometimes useful (or at least informative)
The really interesting thing is that anyone is surprised - given that the UK has something like a century and a half of form in the "clandestine" submarine cable tapping business. The UK controlled every commercially useful submarine cable in the world up until (at least) the first World War. The official rationale being that the cables were there as a result of building, and to control, the British Empire. They were tapping away for 50 odd years before anyone either twigged or at least were in a position to get uppity about it. Is it any wonder that they continue doing it, and on any satellite links they can get hold of as well?
As the UK is about to have yet another war anniversary orgasm (sigh), El Reg's readers might like to research some of the antagonism that the US had for the UK's wire tapping activities - and the use that the information gleaned therefrom was used for - against what the US saw as its interests. And how that coloured the US's attitude toward the UK during the 20th Century and since.
So save the feigned anger. It's pointless and won't change anything. You should all know what to do, to obtain a measure of privacy, go ye forth and do it.
Nah... no in-building or underground coverage. Crack that and you are in with a shout though.
Just like the current one.
Has anyone got a clue what the syllabus might look like? What operating systems will it cover? Which APIs? Got any interesting and/or worthwhile sample programs that the little darlings might have a chance of completing? Given that course work is no longer going to count, how are they going to examine programming? 24 hour / Weekend Hack-Fest?
Obviously the programming languages taught will be out of date long before pupils pop out of the system into useful work, so I won't bother asking which ones will be taught. But somehow I doubt it will be C or assembler.
Re: Welcome to the pretty countryside
Just to give you an idea of the volume of wood that DRAX might consume: I have a 25KW (nominal) gasifying wood log boiler that is 92% efficient. During the heating season I put through about 1m3 of dry waste wood every week (it depends a bit on how much hardwood there is in the waste). A m3 of dry wood weighs about 350-500Kg (again depending). Double->triple that for freshly felled logs. Fresh (> 20% moisture content) wood will reduce efficiency by up to 80% (depending on species and water content).
Each of DRAX biomass sets will burn about 2.4 millon tonnes rising to 7.5 million tonnes in 2017 when they all convert. It is claimed that they will need 1.2 million hectares of forest on a continuous basis to supply this. I think that they are using optimistic growth factors for their forest regeneration to get something as low as this and, in any case, the US (unlike the UK and Europe) is not noted for restocking and managing their forests. They are still mining virgin forest there. And that 7.5 millions tonnes will be mainly wood pellets and thus dry. That implies at least double the weight per year of actual trees.
Welcome to the pretty countryside
And the dark skies we have here in Sussex. Hang on, aren't they even darker than usual? Why yes, we seem to have another power cut. The fifth this year in fact.
On another note, the problem in the UK is not generating capacity as such. We actually have several mothballed power stations, some of which could be switched on within days. The real problem is the balls up of an electricity market where the incentives dictate that, for instance, gas powered stations can't be economically run (because one needs them to be running for at least 10 hours per day to make some money) whilst, at the same time, fields full of containerised diesel generators are being planted to cope when the wind doesn't blow.
In the meantime the DRAX power station is "converting to biomass". I can't imagine that is going to last when someone realises that, within a very few years, it will consume every burnable stick currently being grown in the UK (and probably Scandinavia as well) . It make a mockery of all that effort now being made to put back the forests that once covered the UK.
Re: Well, thanks for not descending into Randian lunacy
To state the bleeding obvious: They may live longer, but they are very unlikely to pay more tax per year of life as a result (unless, of course, the government ups everybody else's tax to compensate).
The elephant in the room
Is, of course, all the wasted heat that any power plant has to get rid of generating all that 'leccy.
Personally, I tend to agree with Lewis that the menace of CO2 is somewhat over done. It can't help that burning any kind of coal has, historically, dumped more many times more radioactivity onto the ground, as well as other solid pollutants both onto the ground and into air than all the nuclear + their accidents put together (by several orders of magnitude).
However, none of them are thermally efficient on any objective measurement. Then there is heat wastage during usage. If one ignores the comparatively tiny amount of useful work that 'leccy driven widgets do, as well as the woeful insulation status of most human 'leccy usage, one is drawn to the conclusion that all power stations are essentially atmospheric heaters with a wide distribution network making sure than few parts of the planet escape some local heating. Oh and BTW physics tells what all that "useful work" ends up as.
So current power generation digs something out of the ground and uses it to heat its surroundings. The heating might be local, but do enough of it for long enough, over large area of the planet and one has to ask if there is a better definition of "Global Warming". What we are doing is systematically overloading the planet's ability to dump excess heat. The other "bad" things simply add to the problem.
So are we all doomed? Well yes, obviously. However if one needs to choose"fossil" then nuclear is easily the least polluting fuel generation method. But solar based generation has one advantage in that they can never *add* to the local heating of an area. The plant even (eventually) makes a profit on the energy expended on its manufacture - unlike windmills.
I see a small ray of sunshine in the German government has belatedly twigged what periodic generation of 40% solar energy does to a distribution grid and is starting to think about subsidizing house sized energy storage systems to bring down the cost. To the point that households might largely (in the sunnier seasons in Europe) be electrically self sufficient (and therefore excess heat generationally "neutral" for a large part of a year - but they aren't thinking of that bit - yet).
If they succeed in bringing the cost of storage at the same rate as the reduction in cost of PV cells, together the continuing improvement in PV cell 'leccy conversion rates, then the agreement that UK PLC has just made with France and China will look even more expensive than it currently does. It may never get finished.
I've put my coat on, as it's cold.
Another "Eye of Sauron" transport mechanism?
They could get yet another view of the world from their barges and, obviously, do some extra erm... triangulation on all those (open, obviously) wifi hotspots that they will be able to "see" along their journeys around the bay and up river.
Here's a little job: try name and address deduplication. For about 60 million addresses (for starters). And get them all right.
That is a real problem, has nothing in particular to do with NP. Probably doesn't even count as "computer science". But it's bloody hard.
Re: Don't forget the data structures
* Cough, erm I think you mean Pascal.
How many professional programmers have a CS degree anyway?
And does it make any difference at all to the end result? Surely anyone calling themselves a programmer should be able to recognise their limitations and will be able to find and then leverage other people's work.
Nearly all the work I have done in my professional life (now 40 years) has been anything from straight forward -> really quite hard. Only two have been NP hard. Both of these got solved using good old "monte carlo methods" and using existing libraries (NAG in one case and something that was written for a different, but related problem). Both gave satisfactory answers and in a very short time (as these things go).
I don't have a CS degree.
Does the Indian Government know about this?
I only ask because the Indian Government has, historically, been extremely paranoid^Hreticent about making available the exact lat/longs of stuff that it considers important or just "useful to an enemy" (read: any of India's neighbours).
One of the standard tests of "competence" they apply to (probably non-Indian) prospective mapping companies, that supply to organs of the Indian state, is whether that company can discover the nature and size of the offset that is routinely applied to mapping data v WGS84 coordinates. One won't get this information from any official source, one has to divine it oneself. Not that this is in any way difficult - it's just annoying.
I'm clearly a Luddite
But has anyone considered using a mule as a pack carrier at all? It is trainable, it will defend itself (trust me here), handles any terrain that a human might want to (and then some), runs on a grass (or anything else edible lying around) and does more Kg/Km/unit of energy consumed. A mule is also much cheaper to buy and, with a bit of organisation, easier to source.
I can see my coat.
Re: Fixed Length
One has a choice: either stateful, shorter, but potentially fragile and non-self synchronising or UTF-8. Me? I choose UTF-8. But then I spend a large part of my programming life dealing with radio based comms protocols which means - by definition - I am rather strange.
Oh, and it doesn't help that I spent a lot of time in my formative years having to deal with 5 channel paper tape...
Some (considerable) time ago, the FAA permitted pilots to carry on and use iPads containing flight data (such approach plates, flight plans, manifests and the aircraft manual) during "all phases of the flight". The rationale being that the physical size and weight of the paper was exceeding safe limits - together with the real problem of: "where is that sodding check list?". The FAA also identified that using a slab meant that they could routinely check compliance with (for example) check list use.
So why has it taken this long to allow the cattle in the back to fondle their slabs?

Re: "What is wrong with this idea?"
They are available, houses have been built with them, but they are significantly more expensive both to buy and then get past the planners who don't seem to be with the zeitgeist (unless one lives in Germany, obviously).
Re: Thorium reactors
No-one said anything about "Big-Oil". And you're right that this might only be an argument in the US and then only if they decide not to play.
There is simply too much money staked in the uranium fuel cycle plant that both exists and is planned. No-one in industry wants to "waste" money punting on some "new" (but actually older than the uranium reactor) design(s). As for the politicians, they don't want to invest money in anything useful and they want to keep "their" bomb.
Re: Thorium reactors
Because there are too many vested interests, both business and political, preventing it.
Re: Storing H2 is not a problem
And, as it happens, is one of the big issues with some thorium reactor designs. To be fair, dealing with the side effects of hot H2 in traditional reactors is a bit of an issue as well.
Re: Do have a extra CPU
Not much point putting it in a cpu here in deepest Sussex. No 3G. Not for miles.
Linus really lost it? Really???
A quick read of the thread will show that a) Linus was (for Linus) being *very* mild mannered and b) it was part of a serious discussion about the nature, consequences and frustrations of trying to cope with explosion of interfaces / features of ARM based systems. As someone that occasionally has to dabble in these areas I share his pain - but probably in more explicit terms.

Er... Who writes these headlines?
Is this a reasonable way to go about reporting it? It just might be true and people may have died.
Come on El Reg. We all like a joke and a laugh at the IT industry's expense, but is this a suitable case for this treatment?
For them's that are interested...
This is a useful compendium site that gathers together all the various sun related data, graphs and pictures. It updates itself regularly, so that one can watch the whole thing unfolding. As usual on these occasions the southern part of the UK will be under cloud and rain during this CME's likely earthfall.
And is illegal in the UK
As case law has (more than once) defined this as "stealing electricity". As in the celebrated case of a a farmer using fluorescent tubes with some wire attached to the ends to light his cowshed. He was in the near field of a some large (IIRC BBC) transmitter.
The article mentions various large US tech companies paying dividends. Unfortunately, very few of them actually do this and, when they are forced to (because they won't do it voluntarily), they use all sorts of shenanigans to pay as little as possible, whilst trying to protect their huge (usually offshore) cash piles.
Re: If it's "not ready for prime time" ...
You'll be accusing ElReg that they are BBC huggers next.
Is the "Java machine" up to date?
I notice, in an other article today, that only 1% of java implementations are up to date. Not that it matters much as there has been yet another 0-day disclosed today. One does wonder what version(s) of java sim cards run on and how it is proposed to keep them current.
One could also speculate whether there might be resistance from our Lords and Masters if any attempt is made to improve sims' security.
A UK perspective from history
Many years ago, when Great Britain had an Empire and the US was still ramping up its financial and industrial power (say late 1800s -> 1939[ish]), this country owned and/or controlled most of the international and intercontinental communications cables in the world. This started off as a side effect of running the Empire, but it became apparent, very early on, what the possibilities were when foreign governments and companies embraced the advantages of "instant" communications.
GB, having grasped the usefulness of being able to tap the cables, then went to a great deal of trouble to try to prevent other states from laying cables of their own on routes that did not touch one of the GB controlled nodal points. And GB was, for many years, successful at this - until those pesky Americans started throwing their growing weight and money around...
There are many papers out there on this subject, but they all point to the same result: GB wanted to eavesdrop on as much communications traffic as it could.
So why on earth should anybody be surprised that a) the US does too and b) the UK still carries on recording everything that flows in, out or around the country?
Those that ignore history are destined to repeat it [or apparently be constantly surprised].
Unlike the Dutch, whom nick good words from anyone provided that they sound "right" when pronounced in a Dutch way (possibly having had their endings modified to Dutch norms). It also has to be said the Dutch like to use pure English words (or phrases) for emphasis.

He is a "hacker" because it changes the narrative away from the connotations of the word "leaker". "Hacking" is evil. "Leaking" information means that what he says might be (gasp) true?

Re: Diesel Bug
Specifically, there is a problem with biodiesel in that it is hygroscopic, thus providing more house room for bugs. Another *major* problem with biodiesel is that is much more corrosive to the sorts of "rubber" glands, seals and pipework that "traditionally" are used with mineral diesel guzzling engines. This is why many diesel cars specify what percentage of biodiesel is allowed in the the road fuel that cars burn.
The impending road crash(es) that will occur very soon when the EU start enforcing much higher biodiesel content for road cars is for another article...
If you pick the right spot, it probably can (poach an egg).
One does wonder what the power budget of this beast is.

Re: No you choose your degree at 13
Many of the best programmers (as opposed to computer scientists) I know are music, essay writing arts or (intriguingly) chemistry graduates. Arguably, some of the worst were maths graduates.
This has nothing to do with intelligence or knowledge. Let's face it squarely: at the end of the day a talented programmer can structure and design a reasonable system in his (sadly yes) head while you wait. He then has to spend the next three to six months writing it down. That's a bloody long (and very *precise*) essay/dissertation by anyone's standards. And he has to do that year in, year out, during his programming career.
Programming is craft, not science. It is more akin to carpentry with book authorship than abstract maths.
Pascal had a use (for me at least)
"Algorithms + Data Structures" by Nikki Wirth was probably the most influential book on programming I ever read. It caused me to change from Algol to Pascal (and later avoid Pascal 68/Simula etc) as my high level language. Anything was better than Fortran and (spit) Basic. Mind you I was still writing a load of machine code, assembler and Plasyd at the same time. So when I came across unix and C in 1981 I was ready for the change. I have been writing in C ever since. I have never understood why people think it is so hard to use.
