Home Entertainment by Microsoft

Microsoft has announced Windows XP Media Center Edition, a version of the Windows operating system that turns a PC into a media center. The new product, formerly code-named Freestyle, is targeted at digital media enthusiasts, college dorm rooms and teen bedrooms. The interface will feature a Start button which brings up a screen to replace the standard Windows graphics with a simple design that provides quick access to various entertainment media and functions (see screenshot). It will not be available as a separate operating system, but will be packaged together with PCs that are specially designed to support its media features. These systems, planned for availability from HP, NEC, and Samsung will be priced in the $1,000 to $2,000 range, and will have extensive digital music, video, TV and DVD video playback capability, along with their own remote control. There are stories about the new system on MSNBC and BBC News.

Truly Anonymous Surfing?

This article in Wired talks about a new method for masking online identities to provide ultra-anonymous Internet access. It was developed by Hacktivismo, an offshoot of the hacker collective Cult of the Dead Cow (cDc), and is called “Six/Four”, named after the June 4, 1989 massacre in Beijing’s Tiananmen Square. Six/Four combines peer-to-peer technologies with Virtual Private Networking (VPN) and “open proxy” connections, which allow one computer to establish direct, secure communications with another over the Internet. Traditional VPNs take the information along a single path from Point A to Point B. Six/Four’s route is more circuitous, sending its tunnel through a series of computers on its peer-to-peer network before heading to the public Internet. Data goes from Point A to Point K to Point Z to Point G, only eventually winding up at Point B. Each link in the chain only knows the link immediately before, not the final destination. Since every server along the way requires separate search warrant in order to view that computer’s logs (if they even still exist) to get your IP address, the approach adds layer after layer of anonymity between client and server. One developer says “It’s like a highway that’s redesigned for every Brinks truck that rides on it.”

From Avatars to Advertising

This article in the LA Times (free registration required) reveals that companies are using artifical agents called “digital buddies” to pitch their products on Instant Messaging services. These bots are programmed to make friends and small talk, and they’re eerily good at it. They take cues from questions and answers, searching databases for conversational fodder, and then urge people to buy Ford trucks, check out the eBay auction site and take in “The Lord of the Rings.” Most buddies are programmed with personalities that appeal to their target audiences. For example, ELLEgirlBuddy, the Internet ego of teen magazine ELLEgirl, is a redheaded 16-year-old who likes kickboxing, the color periwinkle and French class. Though most users are aware they are communicating with a computer, some engage in deep conversation with these buddies, talking to them as they would to friends. Many of the companies are using technology from ActiveBuddy, which offers the BuddyScript Server and Software Development Kit for building and deploying interactive agents.

XML Standard for Business Reporting / Accounting

TechWeb reports in this ARTICLE on Edgar Online‘s support of XBRL, an XML standard for companies to publish and distribute financial reports.

Such a standard would be a strong movement in the direction of efficient valuation and pricing of fundamental business characteristics. Arbitrage pricing theory could be applied using each XBRL tag as a factor, resulting in the ability to calculate values and sensitivities for stock prices based on changes to the underlying fundamentals in detail.

Copyleft 101

NewScientist has a very good survey article regarding copyleft. They discuss the legal implications of waiving the exclusivity rights, as well as the philosophical differences in vision regarding the commercialization of intellectual properties.
