Old Islamic Tile Patterns Show Modern Math Insight 538

arbitraryaardvark writes "Reuters reports that medieval Muslims made a mega math marvel. Tile patterns on middle eastern mosques display a kind of quasicrystalline effect that was unknown in the west until rediscovered by Penrose in the 1970s. 'Quasicrystalline patterns comprise a set of interlocking units whose pattern never repeats, even when extended infinitely in all directions, and possess a special form of symmetry.' It isn't known if the mosque designers understood the math behind the patterns or not."

Halo 3 To Have 'Mute the Jerk' Button 260

Eurogamer is reporting on comments from the Bungie website. A feature for the upcoming Halo 3, that they've just announced, will be most welcomed by aging FPS players tired of hearing high-pitched squeals through their headsets. When playing an online match, players will be able to hit a button and then choose one of the gamertags playing the game. The result: a total mute on that player for the remainder of the game. They don't mention it on the site, but one would hope the Xbox Live servers are taking metrics on this activity, to be used in calculating the player's reputation. The more you mouth off, the worse you look to future players. Anyone have some other feature they think might make online gaming better?

MS Office Zero-Day Under Attack 172

paulBarbs writes "Microsoft is warning users to be on the lookout for suspicious Excel files that arrive unexpectedly — even if they come from a co-worker's e-mail address. In an advisory, Microsoft confirmed a new wave of limited "zero-day" attacks was underway, using a code execution flaw in its Microsoft Office desktop productivity suite. Although .xls files are currently being used to launch the spear phishing attacks, Microsoft said users of other Office applications (Word, PowerPoint, Outlook, Access, etc.) are potentially at risk."

Vista Family Discount Keys Found Not Compatible 394

acousticiris writes "Many (if not all) users who took advantage of Microsoft's Vista Family Discount have been issued invalid installation keys and cannot install Windows Vista Home Premium. Microsoft says, 'There is no expected time period for a fix at this time.' According to the article, the keys are valid for something, just not Windows Vista. Perhaps it's just too simple to issue these folks new keys and send them on their way."
It's funny.  Laugh.

Microwave Experiments Cause Sponge Disasters 517

gollum123 writes "Reports about a study that found microwave ovens can be used to sterilize kitchen sponges sent people hurrying to test the idea this week — with sometimes disastrous results. A team at the University of Florida found that two minutes in the microwave at full power could kill a range of bacteria, viruses and parasites on kitchen sponges. They described how they soaked the sponges in wastewater and then zapped them. But several experimenters evidently left out the crucial step of wetting the sponge. "Just wanted you to know that your article on microwaving sponges and scrubbers aroused my interest. However, when I put my sponge/scrubber into the microwave, it caught fire, smoked up the house, ruined my microwave, and pissed me off," one correspondent wrote in an e-mail to Reuters."

Year of the Mainframe? Not Quite, Say Linux Grids 222

OSS_ilation writes "IBM touted 2006 as a resurgence year for the mainframe, but not so fast. At R.L. Polk and Co., one of the oldest automobile analytics firms in the U.S., an aging mainframe couldn't cut it, so the IT staff looked elsewhere. Their search led to a grid computing environment — more specifically, a grid computing environment running Linux on more than 120 Dell servers. The mainframe's still there, apparently, but after an internal comparison showed the Linux grid outperforming the mainframe by 70% with a 65% reduction in hardware costs, Polk seemed content banishing the big box to a dark, lonely corner for more medial tasks."

Dark Corners of the OpenXML Standard 250

Standard Disclaimer writes "Most here on Slashdot know that Microsoft released its OpenXML specification to counter ODF and to help preserve its market position, but most people probably aren't aware of all the interesting legacy code the OpenXML specification has brought to light. This article by Rob Weir details many of the crazy legacy features in the dark corners of OpenXML. As it concludes after analyzing specification requirements like suppressTopSpacingWP, 'so not only must an interoperable OOXML implementation first acquire and reverse-engineer a 14-year old version of Microsoft Word, it must also do the same thing with a 16-year old version of WordPerfect.'"

MySQL Quietly Drops Support For Debian Linux [UPDATED] 339

volts writes "MySQL quietly deprecated support for most Linux distributions on October 16, when its 'MySQL Network' support plan was replaced by 'MySQL Enterprise.' MySQL now supports only two Linux distributions — Red Hat Enterprise Linux and SUSE Linux Enterprise Server. We learned of this when MySQL declined to sell us support for some new Debian-based servers. Our sales rep 'found out from engineering that the current Enterprise offering is no longer supported on Debian OS.' We were told that 'Generic Linux' in MySQL's list of supported platforms means 'generic versions of the implementations listed above'; not support for Linux in general." Update: 12/13 20:52 GMT by J : MySQL AB's Director of Architecture (and former Slash programmer) Brian Aker corrects an apparent miscommunication in a blog post: "we are just starting to roll out [Enterprise] binaries... We don't build binaries for Debian in part because the Debian community does a good job themselves... If you call MySQL and you have support we support you if you are running Debian (the same with Suse, RHEL, Fedora, Ubuntu and others)... someone in Sales was left with the wrong information"

Microsoft Issues Zero-Day Attack Alert For Word 483

0xbl00d writes "Eweek.com is reporting a new Microsoft Word zero-day attack underway. Microsoft issued a security advisory to acknowledge the unpatched flaw, which affects Microsoft Word 2000, Microsoft Word 2002, Microsoft Office Word 2003, Microsoft Word Viewer 2003, Microsoft Word 2004 for Mac and Microsoft Word 2004 v. X for Mac. The Microsoft Works 2004, 2005 and 2006 suites are also affected because they include Microsoft Word. Simply opening a word document will launch the exploit. There are no pre-patch workarounds or anti-virus signatures available. Microsoft suggests that users 'not open or save Word files,' even from trusted sources."

Birmingham To Buy More, Not Less Open Source 232

K-boy writes, "Last week, the press (and Slashdot) reported that Birmingham City Council had decided to ditch its open source project because a report said its trial had cost £100,000 more than it would have cost to buy Windows. However, Techworld has discovered that the opposite is true, and the Council is actually planning to use more open source software as well as to roll out Linux in the next few years. The head of IT was interviewed and he gives a fascinating rundown of the problems he had getting open source working with his systems. More interestingly, he points out that now the trial is over and he and his staff have the technical skills, they expect to save lots of money in future by going open source. Oh, and the report's figures were based on the special rates that Microsoft gives Councils just to make sure the short-term budget look worse — £58 for a Windows license as opposed to the normal £100."

Life Without Traffic Signs 604

zuikaku writes, "Der Spiegel has an article titled European Cities Do Away with Traffic Signs reporting that seven cities and regions in Europe are doing away with traffic signs, signals, painted lines, and even sidewalks. With the motto 'Unsafe is Safe,' the idea is that, when faced with an uncertain, unregulated situation, drivers will be naturally cautious and courteous. Then again, they may end up with streets jammed with pedestrians, bicyclists, and cars like some places in India and China." I can't see this idea getting traction in the U.S.

Ballmer Says Linux "Infringes Our Intellectual Property" 820

Stony Stevenson writes "In comments confirming the open-source community's suspicions, Microsoft CEO Steve Ballmer Thursday declared his belief that the Linux operating system infringes on Microsoft's intellectual property." From the ComputerWorld article: "In a question-and-answer session after his keynote speech at the Professional Association for SQL Server (PASS) conference in Seattle, Ballmer said Microsoft was motivated to sign a deal with SUSE Linux distributor Novell earlier this month because Linux 'uses our intellectual property' and Microsoft wanted to 'get the appropriate economic return for our shareholders from our innovation.'" His exact wording is available at the Seattle Intelligencer, which has a transcript of the interview. Groklaw had an article up Wednesday giving some perspective on the Novell/Microsoft deal. Guess we'll have something to talk about in 2007, huh?

The Corporate Invasion of Second Life 62

Tyburn Franklie writes "Second Life is entering its 'second phase'. With big-name brands colonizing its virtual earth and the media getting worked up into a frenzy of hype, the alternative world is looking more and more like the old one. There are even worries about virtual office etiquette (sorry guys: no guns in the office). And now Linden Labs has words of warning for would-be corporate warriors seeking a Second Life: 'If you are not authentic and do not offer anything to the community, you are likely to be ignored, at best.' Sage advice — whatever world you're in." A lot of overhype here, I think.
