The Stamford, Connecticut-based company World Wrestling Entertainment issued a press release last night, stating that wrestling performer John Cena is expected to recover from his injuries, after a surgery.

WWE Medical Program head, described in a press release as a “renowned neurosurgeon” Dr. Joseph Maroon performed the operation on Cena, after he sustained injuries during the SummerSlam match on Sunday August 24. He suffered a herniated disc in his neck, in a lost match against a wrestler named Batista.

Just hours after surgery, he visited the locker room of the SmackDown/ECW taping, commenting to the WWE website that: “I feel great. Dr. Maroon is fantastic. He explained every possible procedure he could and could not perform, and the potential risks of all of them. I explained to Dr. Maroon not only my immediate goals, but also my long-term goals. He took them all into consideration and recommended the most commonplace procedure with the least amount of side effects.”

While the option of fusion surgery was chosen previously by other WWE wrestlers (Edge, Steve Austin, Chris Benoit), Maroon removed a fragment from Cena’s spinal cord, which had been blocking a nerve.

The operation lasted 90 minutes; recovery is expected to take three months, instead of a previously suggested 12-14 months.

In his WWE career, Cena is a three-time WWE Champion, a three-time United States Champion, and a two-time World Tag Team Champion. He also won the 2008 Royal Rumble. Before being promoted to the main WWE roster, Cena trained in and wrestled for Ultimate Pro Wrestling and Ohio Valley Wrestling, holding the top titles of both promotions.

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.

A car driven by an 80-year-old man has hit a five year old girl at a pedestrian crossing at Frenchs Forest Road in Seaforth, in Sydney‘s north at 4 p.m. AEST.

Sophie Delezio, 5, was rushed to Sydney Children’s Hospital. She has injuries to shoulder, jaw, numerous rib fractures but her most serious injury is bleeding around her left lung. She is expected to fully recover. She is expected to be in intensive care for three weeks. She is not expected to have to undergo surgery. A drug called NovoSeven is credited with stopping the bleeding around her lung.

The 80-year-old driver of the car that crashed into her has been arrested on negligent driving causing grievous bodily harm and failing to give way at a pedestrian crossing. He is expected to front Manly Court on 15 July 2006.

Sophie was also involved in an accident involving a driver crashing into the Roundhouse Childcare Centre on December 15, 2003 causing her severe burns to 85% of her body. She also lost both feet, some fingers, and her right ear.

Member states of the eurozone have offered to give Greece thirty billion euro in emergency loans for the debt-stricken country, should the latter want it.

The loans’ price will be determined using formulas by the International Monetary Fund (IMF), and will be set at around five percent.

The Luxembourgish prime minister, Jean-Claude Juncker, speaking on behalf of eurozone finance ministers, commented that “[t]he total amount put up by the eurozone member states for the first year will reach 30bn euros.” He added that “[t]his is certainly no subsidy” to Greece.

The prime minister also noted that financing would be “completed and co-financed” by the IMF. European Union monetary affairs chief Olli Rehn remarked that the IMF would make a “substantial contribution” to the loan package as well, perhaps around ten billion euros.

The Greek economy has spent more than it has earned for several years now, and currently faces a budget deficit equal to 12.9% of its economic output, or a total debt of 300 billion euros. The country intends to try and reduce the deficit to 8.7% this year.

The U.S. Senate unanimously confirmed on Wednsday the nomination of Dr. Michael Griffin to head the National Aeronautics and Space Administration (NASA), making him the 11th administrator of the US-based space agency. He takes office at a time when NASA is busy with preparations for the return to flight of the space shuttle Discovery, expected sometime during the launch window of May 15 through June 3, 2005.

The presidential nominee Griffin was the head of the Applied Physics Laboratory’s Space Department at Johns Hopkins University, a position he held almost a year. Prior to that, he was a chief engineer at NASA before coming over from service as Deputy for Technology at the Strategic Defense Initiative Organization. He has made a career of the aerospace field.

Griffin was critical at times of U.S. priorities in space exploration by questioning its continued commitment to the International Space Station. Griffin, in testimony before the House Science Committee in 2004, outlined more ambitious plans for human exploration and settlement of the solar system in which he believes the United States should play a key role.

In a statement during his April 12, 2005, confirmation hearing before the Senate Commerce Committee, Griffin said, “In the twenty-first century and beyond, for America to continue to be preeminent among nations, it is necessary for us also to be the preeminent spacefaring nation,” with a spirit of discovery similar to the exploration of the New World by Columbus with the support of the Spanish crown.

Griffin, 55, notably holds seven academic degrees from various institutions, including a bachelor’s degree in physics; master’s degrees in aerospace science, electrical engineering, applied physics, civil engineering and business administration; and a PhD in Aerospace Engineering from the University of Maryland.

Pope Benedict XVI spoke with astronauts aboard the International Space Station yesterday, marking the first time a pope has conversed with astronauts in orbit.

Organized by the European Space Agency (ESA), the call originated from the Vatican Library at 7:11 am Eastern time. German ESA astronaut Thomas Reiter, president of the Italian Space Agency Enrico Saggese, and General Giuseppe Bernardis of the Italian Air Force were also in the room at the Vatican. Aboard the spacecraft were Italian, U.S., and Russian crew members of the Endeavour STS-134 mission and Expedition 27.

Endeavour commander and U.S. astronaut Mark Kelly greeted His Holiness aboard the spacecraft. The Pope wished Kelly’s wife, Arizona Rep. Gabrielle Giffords, well as she recovers from an assassination attempt that took place in January. Doctors inserted a hard plastic implant, or a bone flap, into Giffords’s skull last Wednesday. The Pope also asked of the astronauts’ impressions of the planet from space.

“We fly over most of the world and we don’t see borders, but at the same time we realize that people fight with each other and there is a lot of violence in this world,” Kelly said. The Pope sent his condolences to Italian astronaut Paolo Nespoli, whose mother died earlier this month while he was in space.

In February 2017, the Iranian Chess Federation announced two teenage chess players, Dorsa Derakhshani and her younger brother Borna Derakhshani, were banned from representing the national team. The federation announced their decision although Dorsa Derakhshani had previously decided and informed the chess federation she did not wish to play for Iran.

Dorsa Derakhshani is currently 21 years old and holds the International Master (IM) as well as Woman Grand Master (WGM) titles. Her brother, Borna, plays for the English Federation and holds the FIDE Master title.

Dorsa Derakhshani was banned since she did not wear a hijab, an Islamic headscarf, while competing at the Tradewise Gibraltar Chess Festival in January 2017. Under the laws of Islamic Republic of Iran, hijab is a mandatory dress code. Her brother Borna Deraskhsani was banned for playing against Israeli Grand Master (GM) Alexander Huzman at the same tournament. Iran does not recognise the existence of Israel, and previously, Irani athletes have avoided playing against Israeli athletes.

Mehrdad Pahlavanzadeh, the president of the country’s chess federation, explained the decision to ban the players saying, “As a first step, these two will be denied entry to all tournaments taking place in Iran and in the name of Iran, they will no longer be allowed the opportunity to be present on the national team.” ^{((fa))Farsi language: ?????? ????? ?? ??? ??? ?? ??? ????? ?? ?? ???? ???????? ?? ?? ????? ? ?? ??? ????? ?????? ??????? ????? ??????? ? ???? ???? ???? ?? ??? ??? ?? ??????? ????.} He further stated, “Unfortunately, something that should not have happened has happened and our national interest is paramount and we have reported this position to the Ministry of Sports.” ^{((fa))Farsi language: ????????? ?????? ?? ????? ????????? ?????? ??? ? ????? ??? ?? ?? ?? ???? ?????? ???? ? ?? ??? ???? ?? ?? ????? ???? ?? ????? ?????.}

IM Dorsa Derakhshani, who currently studies at Saint Louis University in the United States and plays for the United States Chess Federation, discussed her chess career, time in Iran and the 2017 controversy, and her life in Saint Louis with a Wikinews correspondent.

All residents within a half-mile radius of the EQ Resource Recovery chemical plant in southeastern Michigan were asked to voluntarily evacuate on Tuesday due to a chemical plant explosion. ClickOnDetroit reported that nearby residents who choose to stay were told to close their doors and windows.

The plant, located in Romulus, near Wayne, is about 15 miles southwest of Detroit. Initial reports stated that a single explosion in a chemical tank was the cause of the fire. The cause of this explosion has not yet been determined. Detroit ABC affiliate WXYZ confirmed that all employees made it out of the plant before the explosion occurred, and that HAZMAT teams were on the scene of the fire. Wayne County Sheriff Warren Evans announced that no injuries were reported in the initial explosion. However, approximately 32 people were treated for breathing problems at nearby Oakwood Annapolis Hospital, due to the subsequent fire.

The Environmental Protection Agency (EPA) analyzed soot in the area and determined that it did not pose a substantial health risk. The company in question has been the target of numerous enforcement actions by the EPA in the past, including a $240,000 fine in 1999. A major chemical processed at the plant is acetone, the main ingredient in nail polish remover, which is known to be toxic in high dosages, especially to those with lung conditions. Acetone is also an eye and skin irritant. Other chemicals, such as antifreeze, are also processed there. Two Detroit-area law firms have filed class action lawsuits against EQ Resource Recovery on behalf of local residents, and a third is considering similar action.

Romulus is the site of the Detroit Metropolitan Wayne County Airport (DTW), the primary airport for the Detroit area and a hub for Northwest Airlines. However, airport service was not affected. News of this explosion came as a chemical plant explosion in Story City, Iowa happened just a day before and three similar explosions in Texas occurred July 28.

“Just like they told us that our bridges were safe, they also want us to swallow that our power grid is in no danger of a system-wide, no-power-for-weeks crash”, said tenured power grid expert Donald McCormick, a senior contractor with Hydro One, an Ontario, Canada based electricity provider.

Mr. McCormick indicated that in reality though, there’s no question that the system of grids that supply power throughout the continent are in much worse shape than the majority of bridges, levees and borders in Canada and U.S. He has over two decades of experience in all aspects of power grid construction, infrastructure, maintenance, and distribution. During a recent interview, Mr. McCormick compared the ten major interconnected power regions that comprise the “North American Grid”, to a string of Christmas lights that’s been active non-stop since the 1950s. Mr. McCormick’s qualifications include being a licensed red seal interprovincial/interstate electrical engineer and he’s worked at numerous power generating stations mainly in Canada, but also across the U.S. He’s participated in building regional infrastructure related to both generation and distribution. Additionally, Mr. McCormick is Orange Level qualified as an Atomic Radiation Worker (ARW) registered in Geneva, Switzerland.

Mr. McCormick offered his candid assessment of today’s continental “power grid” by making several observations about this critical, civilization-supporting industry. His power plant experience includes both nuclear and coal, and he’s a certified expert in alternative fuel technologies such as wind, solar and hydrogen. He said that, from nuclear to coal, the majority of power generating plants operating across North America have momentous deficiencies, and the collective 10-region “power grid” has not been maintained properly (across the board) since the 1960s. Population growth has created a state in which North American power consumption is far greater than what is being yielded by current technological capacity to generate consumable energy. Mr. McCormick indicated that the infamous August 2003 blackout, in which the Northeastern U.S., Mid-Eastern U.S. and most of Ontario suffered stifling, life-interrupting blackouts, was just the beginning of something much more significant. In reference to the North American Power Grid Initiative, he said that it’s nothing more than a case of, “too little, too late”.

“You’re frequently seeing substandard parts and equipment being employed, on sites across the continent, and being used for sensitive construction projects, often related to components integral to the grid system itself. North American nuclear energy generating plants are among the worst when it comes to safety violations, not only endangering on-site employees with blatant disregard but also literally thousands of people with regard to unregulated, unnoticed pollution and waste being dumped in rivers, lakes and oceans, into the atmosphere and, more specifically, our entire ecosystem,” said McCormick.

Mr. McCormick strongly feels that another major breakdown of the grid system may occur by the end of this year, and he further stated that he’s also concerned that domestic power grid system is in grave danger of being undermined by terrorists.
