stoolpigeon writes "Microblogging service Twitter has undeniably been a hit, with growth rates that were at times in excess of 1400%. The growth was rapid enough that the site became well known for its periodic, and, at times, extensive downtime. Even with these issues, the service continued to grow rapidly, and with celebrities getting into the mix Twitter was quickly on the radar of mainstream media. The ubiquity of Twitter and ever-increasing coverage of 'tweets' has also brought the inevitable backlash. As with anything that gains high-profile popularity, there are plenty of Twitter haters out there, though the role Twitter has played in the recent Iranian elections seems to have brought more legitimacy to Twitter in the eyes of many. With popularity come books, and quite a few are already out there about and for Twitter, but my favorite so far is The Twitter Book by Tim O'Reilly and Sarah Milstein."

CWmike writes "European customers will pay up to twice as much for Windows 7 compared with US users, even though the new operating system will ship without a browser in Europe. Some of the money Microsoft stands to make on the European editions of Windows 7 comes from the weak dollar. Last week, for instance, the dollar fell against the euro the most in a month, hitting $1.41 per euro. For example, Windows 7 Professional, the key retail edition for businesses, will sport a price tag of 285 euros, or $400.60, and £189.99, or $313.84, at Saturday's exchange rate. In other words, EU customers will pay twice the $199.99 U.S. price; U.K. buyers will pay 57% more. And depending on your view on bundling IE, Europe's customers will be paying more for less, with Microsoft's decision to yank IE8 from Windows 7 in an effort to head off EU antitrust regulators, who may still force the company to take more drastic measures."

CurtMonash writes "Web analytics databases are getting even larger. eBay now has a 6 1/2 petabyte warehouse running on Greenplum — user data — to go with its more established 2 1/2 petabyte Teradata system. Between the two databases, the metrics are enormous — 17 trillion rows, 150 billion new rows per day, millions of queries per day, and so on. Meanwhile, Facebook has 2 1/2 petabytes managed by Hadoop, not running on a conventional DBMS at all, Yahoo has over a petabyte (on a homegrown system), and Fox/MySpace has two different multi-hundred terabyte systems (Greenplum and Aster Data nCluster). eBay and Fox are the two Greenplum customers I wrote in about last August, when they both seemed to be headed to the petabyte range in a hurry. These are basically all web log/clickstream databases, except that network event data is even more voluminous than the pure clickstream stuff."

coondoggie writes "So, if the government gave your company $500 million to spend on building a new data center what would you buy and how would you build it? Well, the Social Security Administration is about to find out. As part of the stimulus bill, or the American Recovery and Reinvestment Act of 2009, the SSA got the tidy little sum to replace its National Computer Center. The SSA in fact says it will need closer to $800 million to fund a new IT infrastructure, including the new data center — the physical building, power and cooling infrastructure, IT hardware, and systems applications. (This is addition to a $72 million backup facility currently under construction in Durham, North Carolina)."

Several sources are reporting that work on The Witcher: Rise of the White Wolf, a console port of the popular PC game, has officially been suspended. CD Projekt, makers of the original game, were working with WideScreen Games on the new version. WideScreen says that CD Projekt missed a significant payment for their role in the development, leading them to stop work on the game. They are emphatic that development won't continue until CD Projekt makes good on the debt, but CD Projekt says, "All payments were done on time according to milestone plan. ... Truth is that payments were later than originally planned but this was solely due to delays in production. The delays were growing in the project due to WSG [continuing] to miss the deadlines." The game's future is uncertain.

Time Doctor writes "The de-facto standard in Quake 3 engine technology, ioquake3, has hit version 1.36 recently. It includes a garbage bag full of improvements: in-game VOIP; optional external Mumble (voip); OpenAL; IPV6; anaglyph stereo rendering; Full x86-64 architecture support; Rewritten PowerPC JIT compiler, with ppc64 support; new SPARC JIT compiler, with support for both sparc32 and sparc64; improved console command auto-completion; persistent console command history; improved QVM (Quake Virtual Machine) tools; colored terminal output on POSIX operating systems; multiuser support on Windows systems (user-specific game data is stored in their respective Application Data folders); PNG format support for textures. Of course, there are even more fixes for security holes and other bugs in there. So, if you don't like ads and queues in your Quake 3 experience, get a copy of Quake 3 off Steam and copy your data files and key into your ioquake3 directory."

Three government centers in the UK have been working on a way to use digital technology to help the elderly and the disabled. One of their ideas is a supermarket satellite navigation system to help elderly people who get confused by changing layouts in the aisles. Professor Paul Watson, of Newcastle University, said: "Many older people lack the confidence to maintain 'normal' walking habits. This is often due to worries about getting lost in unfamiliar, new or changing environments." A kitchen for Alzheimer's patients packed with hidden sensors and projectors is also in the works.
