Submission + - The Math of Graphics

dalektcalum writes: Understanding the mathematical foundation of graphics can help anyone be a better graphics programmer. In a recent talk given by Christopher Evensen he covers the important fundamentals that everyone should know. The math is also accompanied by a real world programming example. This talk is an excellent place to get started, or quick review for those already working in the field.

Clear Channel Goes Private and Streamlined 94

7Prime writes "Clear Channel Communications Inc., the nations largest radio, billboard, and entertainment outlet, announced their intention this morning to sell the company to a consortium of private-equity firms for over $26 billion. In addition, Clear Channel's TV division, as well as its smallest 448 radio stations would be sold out of the company and will be looking for potential buyers." From the article: "The buyers, led by Bain Capital Partners and Thomas H. Lee Partners, also are bidding for Tribune Co., which owns several newspapers and television stations. That process is ongoing. If Bain and Lee purchase Tribune, they may be forced to sell certain newspapers and television stations to comply with Federal Communications Commission regulations that prohibit one company from owning a newspaper and radio or television station in the same city. The buyers paid $37.60 per share for Clear Channel, the highest price the stock has seen since mid-2004, and a 25 percent premium on the stock's average price in October. The purchase price includes the assumption of about $8 billion in debt."

Vista Gets Official Release Dates 394

SlinkySausage writes "Five years, three months and five days after Windows XP made its debut, Microsoft will usher its next-generation OS onto the stage. Microsoft has set November 30 as the release date for Vista (and Office 2007) to business customers and January 30, 2007 as the date for the official launch to consumers and The World At Large."

1.50 Downgrader for 2.50/2.60 PSPs Released 127

Cyraan writes "PSP owners rejoice! Hot on the heels of the recent exploit discovery & bricking that resulted from early test versions comes a confirmed working downgrader. The method uses a GTA eLoader that will turn any version 2.50/2.60 PSP, with the exception of those with a TA-082 motherboard (how to check without opening/voiding warranty), into a version 1.50 capable of playing all forms of homebrew. One thing that may not be mentioned specifically in the article: it is recommended you NOT use the 32mb Memory Stick that came with the PSP, as the process creates alot of log files that can fill it up, possibly causing a brick."

Microsoft Releases Vista Hardware Requirements 591

Digital Inspiration writes "CNet reports that Microsoft has kicked off a 'Get Ready' campaign aimed at helping customers prepare for Windows Vista. The site also includes an Upgrade Advisor tool to help people determine just how Vista-ready an existing PC is." From the article: "The marketing programs and upgrade tool are designed to ease some of the uncertainty around Vista well ahead of the back-to-school and holiday shopping seasons, the two biggest PC selling times of the year. Vista had long been expected to arrive by the 2006 holidays, but Microsoft said in March that it would not arrive on store shelves until January."

Grand Theft Auto IV Unveiled On 360 393

Despite expectations that this would be the least eventful of the E3 pre-conferences, Microsoft's Peter Moore drops the news that Grand Theft Auto IV will be on Xbox 360. Rockstar and Microsoft have teamed up to do exclusive episodic content in the GTA gameworld for the 360. Slated to release October 16, 2007 in North America, October 19 in Europe. Other details include lots of support for Live Arcade titles (Sonic, Galaga, Street Fighter II), the official unveiling of Shadowrun for the 360 and PC, the airing of the Halo 3 Teaser Trailer (which is already on Xbox Live), and much discussion of 'Live Anywhere'. This last is an expansion of Xbox Live to PC and cell platforms in addition to the Xbox arena.

PS3 Launch Details Announced 796

Sony's conference offered up reassurance that a number of their titles will be playable at this year's E3. The controller will sense movement, allowing the player to move an onscreen avatar 'naturally'. They also released the system's launch details. The North American PS3 launch will occur on Nov. 17th, 2006. The 20GB HDD version will retail for $499, and the 60GB HDD version will go for $599. They promise 4 million launch units by December 31st. Update: 05/09 03:57 GMT by Z : Apparently, not only does the $499 system have a smaller harddrive, but it has fewer features as well.

Cutting Off an Over-Demanding End-User? 466

SpaceNeeded asks: "Numbers of you will probably recognize the start of the situation. Because I work with systems, I perform occasional builds. This occasionally crosses over to support (especially where it's my kit I'm asked to support). This isn't a problem, nor is it a problem when I get the occasional support query from someone I haven't supplied a system to, but who needs assistance. This is all well and good, but I've had pretty poor year personally. I've lost two relatives and a third is in a pretty bad way in hospital. An eleven year relationship ended a couple of months back, and I'm now having to perform _all_ the domestic tasks that used to be shared. Between these few things and my regular job I'm finding I have a whole lot less time to allow to support calls. What methods do you know of for gently cutting off someone, support-wise?"

SF Wifi More Than Flipping a Switch 114

An anonymous reader writes "News.com is carrying a story looking at the costly rollout of the Google/EarthLink SF Wifi project." From the article: "EarthLink said it expects the project to run to between $6 million and $8 million in initial costs, which include attaching radios and receivers to utility poles throughout the city. Within 10 years it expects the whole network, complete with upgrades and maintenance, to cost about $15 million. Finer financial details of the project haven't been made public, but the plan calls for EarthLink and Google to contribute to the initial cost of building the network. It's not clear what the split between the two companies will be. Once the network is built, Google will pay EarthLink for access to the network on a wholesale basis. In order to make access free to people in San Francisco, Google will use revenue generated from local advertisements to pay for access to the EarthLink network."

RIM Strikes Back, Files Countersuit Against Visto 83

SilentOne writes "Research In Motion Ltd. launched an all-out assault on competitors yesterday, countersuing its latest legal nemesis and introducing software to pre-empt imminent launches by other challengers. The countersuit also gives RIM a chance to move the patent battle to a courtroom where it has a better chance of beating Visto. Visto filed suit against RIM on Monday in the U.S. District Court for the Eastern District of Texas, Marshall Division, which reportedly favours patent holders in 92% of cases heard by the court. Jim Balsillie, RIM's co-chief executive, said the company wants the trial moved to the Dallas area, where RIM's U.S. headquarters are located, for practical reasons. Meanwhile, RIM is giving away a free software package, valued at US$3,000, to hook the e-mail accounts of small businesses and consumers up to BlackBerries instead of competitive devices from Palm and Microsoft."

Apple Sets Tune for Pricing of Song Downloads 396

PygmySurfer writes "Apple Computer on Monday revealed it had renewed contracts with the four largest record companies to sell songs through its iTunes digital store at 99 cents each. The agreements came after months of bargaining, and were a defeat for music companies that had been pushing for a variable pricing model."

French Town Tests Cashless Society 302

SamiousHaze writes to mention a Silicon.com article about an attempt in a French tourist town, Caen, to do away with cash in some locales. From the article: "Among [the locations in the trial] is an underground car park; the town hall; a bus stop which can transmit timetable information; a cinema poster which downloads video trailers to users' mobiles; a local supermarket, where people can pay for their groceries with a mobile phone, and a tourist information sign outside the historic Abbaye des Hommes. By touching the mobile against the 'Flytag' logo at each of these locations, users can pay for services or receive information straight to their phone."

The Future of Computing 182

webglee writes "What will the relationship between computing and science bring us over the next 15 years? That is the topic addressed by the web focus special of Nature magazine on the Future of Computing in Science. Amazingly, all the articles are free access, including a commentary by Vernor Vinge titled 2020 Computing: The creativity machine."
