Comment Re:Exponential Speedup?? (Score 3, Informative) 112

by Catullus (#33608558) Attached to: Two-Photon Walk a Giant Leap For Quantum Computing

This comment isn't accurate. There are problems for which quantum computers are indeed exponentially faster than our best known algorithms running on a standard computer. The most important of these is probably simply quantum simulation - i.e. simulating quantum mechanical systems. This has umpteen applications to physics, chemistry and molecular biology (e.g. drug design).

Submission + - Are all the best games NP-hard? (bris.ac.uk) 1

Submitted by Catullus
Catullus writes: Following in the footsteps of Tetris and Minesweeper, the simple yet addictive multiplatform game Flood-It is the latest puzzle to be proven to be hard — NP-hard, to be exact. This means that there's no way to write an efficient program to beat the game, unless P=NP. This research by computer scientists from Bristol University raises the intriguing question: are these games fun precisely because they're hard for computers to solve, and need a spark of human creativity?

Submission + - Guardian gagged from reporting UK parliament (guardian.co.uk)

Submitted by Anonymous Coward
An anonymous reader writes: The prominent UK newspaper The Guardian has been legally prevented from reporting a question in UK parliament. This is fairly absurd given that the question is a matter of public record (#61) — but the country's special libel laws mean that the newspaper cannot inform the public of what parliament are up to.

The question concerns the oil trading company trafigura, the toxic waste scandal they are involved in, and their generous use of libel lawyers to silence those who would report on the whole thing.

(Dear editors, the reason you should use this submission rather than the one already made is that I've provided more context in the form of what the gagged question is, and what it's about.)

Transparent Aluminum Is "New State of Matter" 406

Posted by timothy from the baseball-bats-will-never-be-the-same dept.
Professor_Quail writes with this interesting excerpt: "Oxford scientists have created a transparent form of aluminum by bombarding the metal with the world's most powerful soft X-ray laser. 'Transparent aluminum' previously only existed in science fiction, featuring in the movie Star Trek IV, but the real material is an exotic new state of matter with implications for planetary science and nuclear fusion."

Wolfram Promises Computing That Answers Questions 369

Posted by timothy from the he's-feeling-lucky-you-feel-lucky-too dept.
An anonymous reader writes "Computer scientist Stephen Wolfram feels that he has put together at least the initial version of a computer that actually answers factual questions, a la Star Trek's ship computers. His version will be found on their Web-based application, Wolfram Alpha. What does this mean? Well, instead of returning links to pages that may (or may not) contain the answer to your questions, Wolfram will respond with the actual answer. Just imagine typing in 'How many bones are in the human body?' and getting the answer." Right now, though the search entry field is in place, Alpha is not yet generally available -- only "to a few select individuals."

Slashdot's Disagree Mail 202

Posted by samzenpus from the well-here's-your-problem dept.
Slashdot has one of the best discussion systems there is. It's grown and adapted over the years to meet various challenges and suit the needs of our users. A lot of time and effort has gone into it and we are always open to user input to help make it better. Some of our best ideas start as user suggestions and we appreciate the feedback. Of course they can't all be gems and sometimes the suggestions we get are unworkable or just bizarre. Here are a few of my favorite unhelpful, helpful suggestions.
It's funny. Laugh.

XKCD Improving the Internet ... Yet Again 204

Posted by CmdrTaco from the oh-oh-monroe dept.
netbuzz writes "Comic creator Randall Monroe suggested in a recent xkcd strip that YouTube comments would be better — or, more precisely, less idiotic — if only those posting them were forced to hear their words read aloud first. Well, YouTube has gone and made this "audio preview" a reality, albeit an optional one. And, it's not the first time that xkcd has contributed to the betterment of the Internet, as those who are familiar with last year's "Internet census" and its use of a Hilbert curve may remember."

New Contestants On the Turing Test 630

Posted by CmdrTaco from the game-on dept.
vitamine73 writes "At 9 a.m. next Sunday, six computer programs — 'artificial conversational entities' — will answer questions posed by human volunteers at the University of Reading in a bid to become the first recognized 'thinking' machine. If any program succeeds, it is likely to be hailed as the most significant breakthrough in artificial intelligence since the IBM supercomputer Deep Blue beat world chess champion Garry Kasparov in 1997. It could also raise profound questions about whether a computer has the potential to be 'conscious' — and if humans should have the 'right' to switch it off."

Slashdot's Disagree Mail 264

Posted by samzenpus from the keep-your-cool dept.
In this week's Disagree Mail, I try to show the range of messages I get. It's not all angry or insane, sometimes it's sent to us for no apparent reason. We start off a little mad, slip into a whole bunch of crazy and finish with someone who has a complaint about racism at his favorite restaurant. Read below to get started.

Scientology Given Direct Access To eBay Database 684

Posted by kdawson from the finger-on-the-scale dept.
An anonymous reader writes "The Church of Scientology can delete auctions from eBay with no supervision under the VeRO program, and has used this to delete all resale of the e-meters Scientologists use. This is to stop members from buying used units from ex-members instead of buying from the official (and very expensive) source. Given Scientology's record of fraud and abuse, should eBay give them this level of trust? Will this set a precedent for other companies that want to stop the aftermarket resale of their products?"

UK Report Slams EULAs 239

Posted by kdawson from the signing-it-away dept.
draevil writes "Britain's National Consumer Council has completed an investigation into the practice of software End User License Agreements(EULAs) with the conclusion that many consumers are signing away their legal rights and agreeing to unfair terms, which they could never have scrutinized before purchase. The report also acknowledges that even if the EULA were available prior to purchase, it would be unreasonable to expect an average consumer to understand the terms to which they were agreeing. Here are the full report (PDF) and a summary." The NCC recommends that the European Commission bring softwre licenses under the same consumer protections that apply to other products in the EU.
