Is Mathematics Discovered Or Invented? 798

An anonymous reader points out an article up at Science News on a question that, remarkably, is still being debated after a few thousand years: is mathematics discovered, or is it invented? Those who answer "discovered" are the intellectual descendants of Plato; their number includes Roger Penrose. The article notes that one difficulty with the Platonic view: if mathematical ideas exist in some way independent of humans or minds, then human minds engaged in doing mathematics must somehow be able to connect with this non-physical state. The European Mathematical Society recently devoted space to the debate. One of the papers, Let Platonism die, can be found on page 24 of this PDF. The author believes that Platonism "has more in common with mystical religions than with modern science."

1.6 Million PCs Track Popular P2P Clients 191

Hodejo1 writes "'Big announcements' are often backed up by a dubiously small data set or not backed up at all. Big Champagne, PC Pitstop and Digital Music News joined forces to analyze 1,661,688 PCs to track 152 unique P2P clients quarterly from September 2006 to September 2007. The result is a definitive list of the most popular P2P software in use. Topping the list by a healthy margin is LimeWire. 'In September of 2007 LimeWire was found on 17.8% of all the PCs polled that month. With regards to market share — counting only those users with at least one P2P application on their systems — LimeWire held a 36.4% share, meaning one out of three P2P users has LimeWire on their system. These numbers are up slightly from September 2006 when LimeWire held a market share of 34.1%'. Meanwhile, uTorrent has made huge gains during this period soaring into second place and posing a genuine challenge to LimeWire."

The Texas Petawatt Laser 174

Roland Piquepaille notes the hype surrounding what the University of Texas at Austin is calling the world's most powerful laser. During a tenth of a femtosecond this laser is 2,000 times more powerful than all the power plants in the US, and is brighter than sunlight on the surface of the Sun. On his own blog Roland points out that UT's is not the first petawatt laser; that distinction belongs to a system installed at Lawrence Livermore National Laboratory in 1996.

Should Mac Users Run Antivirus Software? 450

adamengst sends in an article from TidBITS in which Macintosh security expert Rich Mogull explains why he doesn't use antivirus software on the Mac, and why most Mac users shouldn't bother with it either. The article also touches on the question of when an increasing Mac market share might tip it over an inflection point into more active attention from malware writers. (Last month Apple had 14% of PC sales, but 25% of dollar value.)

State Lawmaker Wants To Ban Anonymous Posting Online 471

bfwebster writes "According to a local news article from last week, Kentucky state lawmaker Tim Couch wants to ban anonymous posting on the internet in order to 'cut down on online bullying', which he says has been 'a particular problem in eastern Kentucky.' His bill would require posters to register with their real names and e-mail addresses under threat of fines. Looks like another battle in the right for anonymous free speech."

DARPA Fractionated Spacecraft Program Starts 59

An anonymous reader writes "Start buying Cold War nuclear shelters and piling up the canned food, because Boeing Advanced Systems has started System F6: 'DARPA's Future, Fast, Flexible, Fractionated, Free-Flying Spacecraft United by Information Exchange space technology program.' In other words: multiple, networked specialized spacecraft swarms that are intelligent enough to perform a single coordinated task together, like analyzing the crops or deciding to destroy humanity, Skynet-style. Actually, it could completely change satellites for the better, according to some experts."

Aging Security Vulnerability Still Allows PC Takeover 282

Jackson writes "Adam Boileau, a security consultant based in New Zealand has released a tool that can unlock Windows computers in seconds without the need for a password. By connecting a Linux machine to a Firewire port on the target machine, the tool can then modify Windows' password protection code and render it ineffective. Boileau said he did not release the tool publicly in 2006 because 'Microsoft was a little cagey about exactly whether Firewire memory access was a real security issue or not and we didn't want to cause any real trouble'. But now that a couple of years have passed and the issue has not resolved, Boileau decided to release the tool on his website."

First Amendment Ruling Protects Internet Trolls 305

I Don't Believe in Imaginary Property writes "A recent ruling by the Court of Appeal of the State of California (PDF) in Krinsky v. Doe H030767 overturned a lower court ruling and decided that the First Amendment right to anonymous speech protects internet trolls, too. Specifically, the ruling said that 'this juvenile name-calling cannot reasonably be read as stating actual facts.' And, even though some of the statements were crudely sexual and accused Ms. Krinsky of being among 'boobs, liars and crooks,' the statements were held to 'fall into the category of crude, satirical hyperbole which, while reflecting the immaturity of the speaker, constitute protected opinion under the First Amendment.'"

LAN Turns 30, May Not See 40? 279

dratcw writes "The first commercial LAN was based on ARCnet technology and was installed some 30 years ago, according to a ComputerWorld article. Bob Metcalfe, one of the co-inventors of Ethernet, recalls the early battles between the different flavors of LAN and says some claims from the Token Ring backers such as IBM were lies. 'I know that sounds nasty, but for 10 years I had to put up with that crap from the IBM Token Ring people — you bet I'm bitter.' Besides dipping into networking nostalgia, the article also quotes an analyst who says the LAN may be nearing its demise and predicts that all machines will be individually connected to one huge WAN at gigabit speeds. Could the LAN actually be nearing the end of its lifecycle?"

Apple QuickTime DRM Disables Video Editing Apps 448

An anonymous reader writes "According to numerous posts on Apple's discussion forums (several threads of which have been deleted by Apple), as well as a number of popular video editing blogs, Apple's recent QT 7.4 update does more than just enable iTunes video rentals — it also disables Adobe's professional After Effects video editing software. Attempting to render video files after the update results in a DRM permissions error. Unfortunately, it is not possible to roll back to a previous version of QT without doing a full OSX reinstall. Previous QT updates have also been known to have severe issues with pro video editing apps."

The Tree of Life Consolidates 266

Roland Piquepaille writes "The Tree of Life is an expression first used by Charles Darwin to describe the diversity of organisms on Earth and their evolutionary history. There are only two life forms, — eukaryotes, which gather their genetic material in a nucleus, and prokaryotes, such as bacteria, which have their genetic material floating freely in the cell. Until recently, eukaryotes, which include humans, were divided into five groups. But now, based on work by European researchers, the Tree of Life has lost a branch. After doing the largest ever genetic comparison of life forms they concluded that there are only four groups of eukaryotes."
Role Playing (Games)

World of Warcraft Gold Limit Reached, It's 2^31 479

Mitch writes "Blizzard apparently used signed integers for their World of Warcraft gold values as some people have recently hit the limit of 2^31. "Apparently that amount is 214,748 gold, 36 silver, 48 copper. After you reach that lofty sum, you'll no longer be able to receive money from any source in the game. While some responses to the original posts claim that this exact limit had previously been theorized to exist, there have been no reports of anyone in the game actually achieving this amount via legal means." I guess Blizzard didn't expect anyone to ever get close to that much gold in game."

Corkscrew Cups Could Keep Space Drinks Flowing 181

holy_calamity writes "A Canadian chemical engineer has a novel solution to containing liquids in space. He has been experimenting with corkscrews of ribbon-like material that keep liquids suspended in their center while in microgravity. This effect is caused by the surface tension of the liquids. The helical containers allow the fluid to be sucked out of the coil in one go. In more conventional shapes, such as coffee cups, interaction between the container and the liquid's internal pressure makes the beverage break into annoying globules you have to chase with a straw."

HD DVD Prices Slashed By Toshiba 414

Hellburner writes "Hoping to stop the inevitable, Toshiba has slashed the price of entry-level HD DVD players to $150 — down from the previous $300. 'It's a half-empty, half-full moment for retailers, who could see a sales boost at the same time that some may be faced with price matching from holiday sales ... The theory: play up the acceptance by consumers who have already paid for HD DVD versus those who get it with something else like a gaming console, get more players out there--and dare studios to ignore those consumers. In addition to the sales cuts, Toshiba will launch major initiatives, including joint advertising campaigns with studios.'"
