Submission + - Memory versus disk and cpu - how the balance has changed in 35 years (wordpress.com)

00_NOP writes: Thirty-five years ago a report for Tandem computers concluded (https://www.hpl.hp.com/techreports/tandem/TR-86.1.pdf) that the cost balance between memory, disk and CPU on big iron favoured holding items in memory if they were needed every five minutes and using five bytes to save one instruction. Update the analysis for today and what do you see? Well my estimate that we should aim to hold items that we have to access 10 times a second and that we can now balance instructions and bytes — meaning some common data space saving techniques are more efficient than before.

Submission + - David Cameron says Brits should be taught Imperial measures (wordpress.com)

00_NOP writes: Children in the UK have been taught in metric measures in school since (at least) 1972, but yesterday British Prime Minister David Cameron suggested that they should actually be taught in Imperial measures (which are still in use officially to measure road distances and speeds but not really anywhere else). Is this because he has not got a clue about science or because he is trying to buy off his right wing fringe (who object to "metrication") or because he might be a bit stupid, Oxford degree not withstanding?

Submission + - Scottish independence campaign battles over BBC Weather forecast (wordpress.com)

00_NOP writes: The political battle over Scotland's independence ballot — to take place in September this year — has now moved on to how the BBC project the UK on their national weather forecast. The BBC use a projection based on the view of Britain from geostationary weather satellites and so there is naturally some foreshortening at the northern end of Britain (Scotland, in other words). But nationalist campaigners say this means Scottish viewers are constantly being shown a distorted image of their country which makes it look smaller and hence (in their view) less able to support independence. In response others have suggested that the nationalists are truly "flat earthers".

Submission + - Read better books to be a better person (wordpress.com) 1

00_NOP writes: Researchers from the New School for Social Research in New York have demonstrated that if you read quality literary fiction you become a better person, in the sense that you are more likely to emphasise with others. Presumably we can all think of books that have changed the way we feel about the world — so this is, in a sense, a scientific confirmation of something fairly intuitive.

Submission + - World's biggest "agile" software project close to failure (wordpress.com)

00_NOP writes: "Universal Credit" — the plan to consolidate all Britain's welfare payments into one — is the world's biggest "agile" software development project but it is now close to collapse the British government admitted yesterday. The failure, if and when it comes, could cost billions and have dire social consequences.

Submission + - Time to stand up against Amazon (guardian.co.uk)

00_NOP writes: "Amazon are taking fire in the UK for insisting that publishers pay them for 20% VAT (sales tax) when in fact the online retailer is only paying 3% VAT. Given that the Kindle is rubbish at displaying maths and science and that Amazon are as dangerous a monopoly as Microsoft ever was, is it not time that regulators and consumers stood up to them?"
AI

Submission + - Unreal Tournament to highlight AI breakthrough (wordpress.com)

00_NOP writes: "This coming week is to see AI researchers battle it out through the medium of Unreal Tournament and hopes are high that researchers at Imperial College in London have built a bot that is sufficiently human like that it will, in effect, pass the Turing Test and win a $7000 prize at the IEEE's Conference of Computational Intelligence and Games in Grenada, Spain.
Interestingly, the breakthrough, if proven, comes not from ever greater computational processing of the environment, but in discriminating between less and more important stimuli. In Alan Turing's centenary year one of the points he was ridiculed for in his lifetime — that machines could match human behaviour and 'thought' may be on the point of decisive vindication."

Submission + - Breakthrough in drawing complex Venn diagrams (wordpress.com)

00_NOP writes: Venn diagrams are all the rage in this election year, but drawing comprehensible diagrams for anything more than 3 sets has proved to be very difficult. Until the breakthough just announced by Khalegh Mamakani and Frank Ruskey of the University of Victoria in Canada, nobody had managed to draw a simple (no more than two lines crossing), symmetric Venn diagram for more than 7 sets (only primes will work). Now they have pushed that on to 11. And it's pretty too.
Education

Submission + - OLPC project disappoints in Peru (wordpress.com)

00_NOP writes: "The One Laptop Per Child (OLPC) project has disappointed in Peru, reports the Economist, apparently because in general teachers did not make creative use of the technology. As in other cases the computers seem to have been regarded as ends in themselves rather than tools to help change the ways kids are taught. Quite disappointing for those of us looking for Linux-Global-Domination but not really much of a surprise given the experience in richer countries either."
Education

Submission + - "Radical manifesto" for computer teaching in English schools (wordpress.com)

00_NOP writes: "Everybody (or almost everybody) in England agrees that computing teaching to kids in high school is broken. In response the government promised a radical overhaul and a new curriculum. But then last week it was discovered the government had scrapped the bit of the education department that would develop any such curriculum. Not to be deterred John Naughton, the Cambridge University academic who wrote the "Short History of the Future" has now published his own "radical" manifesto on how computing should be taught."
Google

Submission + - Google wants your voice data (wordpress.com)

00_NOP writes: Peter Norvig, Google's director of research, has told New Scientist that one of the reasons the search engine launched Google Voice is that it needs more human voice data to perfect the sort of "big data, simple algorithm" probabilistic approach to translating voices to text that drives Google Translate. Norvig says that no one is listening to your calls on Google Voice — it is simply their servers trying to the translation right.
Math

Submission + - No proof (yet) of P = NP after all (wordpress.com)

00_NOP writes: "Internet commerce seems safe for now as Russian computer scientist Vladimir Romanov has conceded that his previously published solution to the "3 SAT" problem of boolean algebra does not work. If his solution did work it would have shown that many problems thought to be unsolvable with conventional computers — including decrypting your HTTPS encoded credit card number — would have been solvable in polynominal time. Romanov, who is very far from the sort of crank who normally claims to have proved P = NP or the opposite, is not giving up though..."

Submission + - The Dream(cast) is still over

00_NOP writes: Dreamcast lovers' hopes were raised earlier this month when it came to light that Sega had extended trade mark protection on the console's name. But hopes have now been dashed as even this optimistic take on Sega's motivation makes clear.

For some of us, though, the Dreamcast will never die. Well, not yet, anyway — if you are the same then you can help out this developer by answering a few questions here
Linux Business

Submission + - Michael Dell says Linux server sales are up (silicon.com)

00_NOP writes: "Linux is growing faster in the server space than Windows says the Dell CEO:

"On the server side Linux continues to grow nicely, a bit faster than Windows. We're seeing a move to Linux in critical applications, and Linux migration has not slowed down."

With Netcraft statistics in recent months showing a big increase in Windows as a webserver and with the renewed assault on Linux's legitimacy over the issue of software patents — not a problem for those of us in Europe ;-) — this is reassuring news for FOSS advocates."

Submission + - Political preferences and free software

00_NOP writes: "HateMyTory is the world's first political rating site and occasionally gets blasted or promoted by British bloggers on either side of the political spectrum. But here's something even more intriguing ... when the right come visiting they hate the site but they are disproportionally likely to be users of free software, whether that is just Firefox on top of their Windows box, or all the way with some Linux distro. But when the left rally to the cause they are more likely than not to be proprietary software users, albeit with a big bias towards Apple. If Microsoft's defenders think free software is the road to socialism, why don't the left seem to agree? As a leftie, and a free software advocate, I find this pretty puzzling."
