As of 10:00 p.m EST November 8, 2006, the Democratic Party is projected to have gained control of both the United States House of Representatives and the United States Senate in the 2006 United States general elections. MSNBC projects that the Democrats now control 234 seats in the House of Representatives, 16 more seats than the 218 needed to control the House of Representatives as all 435 seats were up for election. In the Senate, where the balance of power is closer, one-third of all seats were up for grab. As of 10:00 p.m. EST, AP and Reuters were projecting that the Democrats had picked up all six seats they needed to retake the Senate, including the seats of incumbents Rick Santorum (Penn.), Lincoln Chafee (R.I.), Jim Talent (Missouri), Mike DeWine (Ohio), John Tester (Montana), and Jim Webb (VA). The Tester victory by less than 3,000 votes was projected at approximately 2 p.m. EST after the State of Montana announced the results of overnight recounts. Democrat Jim Webb has prevailed in that race by slightly more than 7,000 votes, though his opponent has not conceded and a recount may still occur.

Many media outlets traditionally deliberately spread hoaxes on April Fools’ Day, including notable quality sources such as National Geographic and Science.

The popular British tabloid The Sun wrote that French President Nicolas Sarkozy is to undergo stretch surgery to make him taller than his wife, Italian artist and model Carla Bruni. The report claimed the 5 foot 5 inch leader would be made 5 inches taller in one year using a method by Israeli professor Ura Schmuck. The Sun noted that during his visit to Britain last week, Sarkozy had high-heel shoes while his wife wore a pair of flat pumps.

The Guardian on the other hand ran an article that suggested that Carla would head an initiative by Prime Minister Gordon Brown to bring more glamour, good taste and sophistication to the U.K. general population. This would involve collaboration with Marks & Spencer for high-street fashion and Jamie Oliver for meals and wine.

BBC News had real-looking footage of flying penguins fronted by documentary host Terry Jones, which were actually an advertisement for its new iPlayer.

On Monday, at 10.14 pm UTC, the Wikimedia server cluster experienced a total power failure, taking down Wikipedia, Wikinews, and all other Wikimedia websites.

The servers are housed in a colocation facility (colo) in Tampa, Florida, USA. They occupy two racks, with each rack receiving electricity from two independent supplies. However, both supplies have circuit-breakers in them, and both opened at the same time, leading to a total power failure. All computers immediately went down. It’s normal for fire safety regulations to prohibit uninterruptible power supplies in colos, with the colo providing its own UPS and generator instead. The circuit breakers were on the computer side of this emergency power system, so none of the computers continued to receive power to survive the breaker trip or shut down safely.

The actual reason why the circuit breakers tripped is currently unknown.

When power was restored, it was discovered that most of the MySQL databases that store the data which makes up Wikipedia et al had been corrupted. The main database and the four slaves had all damaged the data on their hard disk drives beyond the ability of the auto-correction to repair. Only one copy survived safely, on a machine that is used for report generation and maintenance tasks, which remained 31 hours backlogged while catching up after an unusually heavy update load during the previous week.

Volunteer Wikimedia engineers worked through the night rebuilding the databases from the sole good copy onto the other servers. The Wikipedia database is over 180Gb in size, making the copying process last 1.5 – 2 hours for every server it was performed upon.

Regular back-ups of the database of Wikipedia projects are maintained – the encyclopedia in its entirety was not at risk. The last database download was made on February 9; all edits since then could only have been laboriously rebuilt from logs and recovered from the damaged database requiring much more time and effort.

Limited read-only service was established late Tuesday afternoon, with editing becoming possible 24 hours after the power failure. Final repairs continue now, as well as upgrades to prevent similar issues in the future. Server-intensive features, such as categories and ‘watchlists’ that display recent changes to selected articles to registered users, remain disabled to ease the load on the recovering systems.

The process which led to the damage originated with the operating system, disk controllers, or hard drives failing to flush the data correctly.

If the power to a database server is cut mid-write, the database may be corrupted and unreadable, however the operating system, hardware, and software are designed to make this very unlikely. In a previous incident in 2004 power was also lost to a server but the database was undamaged.

To avoid such damage, each database server saves a copy of an edit to be applied to the database on a separate storage system before making the actual update to the database itself. This so-called ‘write-ahead logging’ should ensure that in the event of a system crash, the database can be rebuilt from a ‘last-good’ state by replaying the edits saved in the log.

Earlier this year popular blogging site LiveJournal suffered a similar power failure when another customer at their colocation facility pressed an Emergency Power Off button, intended for use only by firefighters. The company suffered database corruption similar to that seen at Wikimedia.

LiveJournal are now fitting UPS to their servers to ensure that they have time to shut down safely in the event of a power failure. Wikimedia was said to be investigating the possibility of fitting similar equipment at the time of this failure.

Several pundits have suggested that the use of another database, such as the proprietary database Oracle or the free PostgreSQL, would have avoided the database corruption seen at the server cluster. A post-mortem of the incident show the failure was in the operating system, or the hardware, or some combination of the two. LiveJournal, which also uses MySQL, reported similar database corruption after their power cut.

The Wikimedia foundation only allows the use of free software on its systems, and future versions of the Mediawiki software will support the PostgreSQL database.

Users are reminded that during times of system failure or excessive demand, they can still search Wikipedia using Google. The articles may be viewed using Google’s cache.

At the 2008 edition of the NHL entry draft in Ottawa, Steven Stamkos’ long-anticipated selection first overall by the Tampa Bay Lightning may have been overshadowed by numerous trades and signings made on the draft floor.

Before even the first pick was made, the Calgary Flames had acquired Mike Cammalleri in a three-way trade. Calgary’s pick, 17th overall was traded with the Los Angeles Kings’ pick, 28th overall, to the Anaheim Ducks. The Kings received the Ducks’ pick, 12th overall. Later, the Flames shipped forward Alex Tanguay and fifth-round pick to the Montreal Canadiens for the 25th overall selection and a 2009 second-round pick.

The Florida Panthers also made a major trade at the draft, moving their captain, Olli Jokinen to the Phoenix Coyotes for two defencemen, Keith Ballard and Nick Boynton as well as the 49th overall selection. The Columbus Blue Jackets made a major trade of their own, picking up R.J. Umberger and the 119th pick overall from the Philadelphia Flyers in exchange for the 19th and 67th picks, overall.

Out of the first 30 picks in the draft, 17 had been traded around between teams. The first round was rich in defencemen; out of thirty players picked, half were defencemen. After Stamkos was picked first overall, the next four picks, Drew Doughty, Zach Bogosian, Alex Pietrangelo, and Luke Schenn were all blueliners.

The hosts, Ottawa Senators, also made numerous moves. The Senators traded up to the 15th pick overall to draft Erik Karlsson. Earlier in the day, the had also resigned Chris Kelly to a four-year, $8.5 million contract extension. Previously, the Senators also waived goaltender Ray Emery. Emery could be bought out as early as today.

The NHL free-agency season starts July 1.

The available information about the phosphorous cloud following the railway accident in the Ukraine last Monday is becoming more and more cryptic.

The political involvement of most media and other factors are causing contradictions among official sources that are making press work extremely hard. Moreover, no one is permitted to enter the accident location. The site of the accident was closed to visitors following the injury of three TV journalists who got too close.

Chinese officials have said that their country’s exports surged last December to edge out Germany as the world’s biggest exporter.

The official Xinhua news agency reported today that figures from the General Administration for Customs showed that exports jumped 17.7% in December from a year earlier. Over the whole of 2009 total Chinese exports reached US$1.2 trillion, above Germany’s forecast $1.17 trillion.

Huang Guohua, a statistics official with the customs administration, said the December exports rebound was an important turning point for China’s export sector. He commented that the jump was an indication that exporters have emerged from their downslide.

“We can say that China’s export enterprises have completely emerged from their all-time low in exports,” he said.

However, although China overtook Germany in exports, China’s total foreign trade — both exports and imports — fell 13.9% last year.

Google has decided to retire the Google Wave social-networking service after one year, citing lack of user adoption.

Urs Hölzle, Google senior vice president for operations, said in a blog post that “Wave has not seen the user adoption we would have liked. We don’t plan to continue developing Wave as a stand-alone product.” Hölzle also said that as a “web app for real time communication and collaboration, it set a high bar for what was possible in a Web browser. We weren’t quite sure how users would respond to this radically different kind of communication.” Google says that it will continue the service until the end of the year.

In May 2009, Google launched Wave as a private beta. A year later, it became open to the public. Wave is an email service that integrates social media features and capabilities into emailing. It integrates IM-like features into its service. The company released components of Google Wave as open source for those to create a similar service. “The central parts of the code, as well as the protocols that have driven many of Wave’s innovations, like drag-and-drop and character-by-character live typing, are already available as open source, so customers and partners can continue the innovation we began. In addition, we will work on tools so that users easily “liberate” their content from Wave,” Google said.
