Following the Pilkhana massacre which occurred February 25 and 26 leaving 74 dead and the inferno at the Bashundhara City shopping mall complex March 13 leaving seven dead, Prime Minister Sheikh Hasina said security measures are being tightened countrywide across Bangladesh.

Fire drills will be enacted at all key-point installations (KPI). Fire fighting systems will be examined by the fire brigade and the public works department (PWD) to ensure functionality. Security measures will be enhanced supplementing areas under private security such as at the Bashundhara City Complex.

The Fire Service and Civil Defence Department requires modernization and needs new equipment to fight fires past the sixth floor of buildings. The Fire Brigade says it needs turntable ladders, snorkels, foam-tenders, lighting units, emergency tenders, fireproof uniforms, and rescue ropes for fire fighting and rescue operations. Transportation to fires is also an issue due to narrow roads, low electrical wires and congestion.

The Bangladesh National Building Code requires fire fighting equipment installed in buildings over seven floors. This code is to be monitored by authorities to ensure compliance with the new guidelines and to make sure buildings are being maintained.

The Bashundhara City Complex opened Monday for shoppers two days after Friday’s blaze. A probe is underway to determine the cause of the fire and to assess structural damage.

Loss of life was minimized as the blaze broke out on a Friday, the beginning of the weekend in Bangladesh, so offices in the upper floors were empty. The lower eight floors are used for shopping and the upper floors are all Bashundhara Group offices.

The mall is valued at Tk 7.0 billion (US$100 million). It is not known if the complex is covered by fire insurance.

It is estimated that it will take over two years to rebuild the area damaged by flames which were burned down to a skeleton. Bashundhara City’s technical advisor, Latifur Rahman, estimated damages at Tk 2.0 billion (US$29m).

Only one television cameraman has been allowed in to film the burnt area. None of the 2,500 shops, cinemas or cafes were burnt by the inferno. The seventh and eighth floors still experience smoke damage, and there was water damage to merchandise.

A three member committee is currently investigating the cause of the fire which will consist of Iqbal Khan Chowdhury, joint secretary of the ministry, representatives of the police, IGP Noor Muhammad, and fire brigade, Director General Abu Nayeem Md Shahidullah. The committee is required to report within the week with their findings. The forensics department is also sifting through the burnt remains.

The Dhaka Chamber of Commerce and Industries has also formed a committee which has begun interviewing witnesses and recording their testimony alongside the government committee.

It has been discovered that 150 closed circuit cameras were not being used when the fire started. Another mystery is why the mall fire fighting system has been found unused.

“In the shopping mall there is an ultra-technology elevator which runs even without electricity but we have found that locked,” Iqbal Khan Chowdhury, joint secretary (Police) of the home ministry, said. “Why the fire burnt so fiercely is a matter to think. We have to see if there was any incendiary substance there. These matters seem to be mysterious.”

Mall management has been asked to submit substances and items which would have been in the upper floors when the fire started. The fire erupted on the 17th floor and spread quickly to the two floors above and engulfed the three floors below. The aerial ladders belonging to the Fire Service and Civil Defence reached as high as the 13th floor of the 21-storey building.

Videos have been sent to the United States (US) for examination to assist in determining the cause of the fire and to help in the damage assessment. Experts from the US are expected to arrive soon.

Firefighters were brought to the rooftop of the 20-storey tower by helicopter. The only fatality in this operation was Baki Billa, a firefighter of Bashundhara City firefighting department, who fell when climbing down a rope from a helicopter to the roof of the building. Three other firefighters made the transition safely. At this same time, the chief security officer was safely rescued by the Bangladesh Air Force helicopter, a Bell 212. Six security officers of the complex also lost their lives.

For the first time ever, NASA has confirmed the presence of water ice on Mars. The Phoenix lander, which landed on Mars on May 25, has confirmed to NASA scientists that the white substance it found while digging a trench on June 15 is water ice.

“It is with great pride and a lot of joy that I announce today that we have found proof that this hard bright material is really water ice and not some other substance,” said Peter Smith, the primary investigator for Phoenix, at the University of Arizona in Tucson, Arizona.

The chunks were left at the bottom of a trench informally called “Dodo-Goldilocks” when Phoenix’s Robotic Arm enlarged that trench on June 15, during the 20th Martian day, or sol, since landing. Several were gone when Phoenix looked at the trench days later. The chunks were visible on June 16, but when Phoenix looked at the trench again on June 19, some of the material had disappeared, implying that it may have evaporated or melted.

“This tells us we’ve got water ice within reach of the arm, which means we can continue this investigation with the tools we brought with us,” said primary investigator for Phoenix’s stereo imager, Mark Lemmon.

Scientists are planning to examine the substance and the soil surrounding it more closely. They plan to test it for signs of organic material and minerals, and hope to find out if the ice was ever a liquid which could have supported microbial life.

In December of 2006, scientists announced that the Mars Global Surveyor captured images of deposits in gullies on the surface of the planet Mars which have been created since the areas were photographed nine years ago. These deposits were believed to be the residue of liquid water breaking out of cliffs and crater walls, carrying sediment downhill through the gullies, and later evaporating. The gullies are located inside the Terra Sirenum crater and the Centauri Montes regions.

In June 2007 the ESA’s Mars Express spacecraft discovered ice deposits in the South Pole of Mars that are larger than the state of Texas. Scientists say that there is enough water in the deposits to cover the entire planet with up to 36 feet of water if the ice was to melt.

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.

Welsh poet Dannie Abse (81) and his wife Joan (78) were involved in a car crash while driving from Golders Green to their holiday home in Ogmore-by-Sea, South Wales. Mrs. Abse died instantly; Mr Abse suffered a broken rib. The driver of the other vehicle was unhurt. The couple was returning from a poetry reading that they both had given.

Dannie Abse is an esteemed Jewish writer who lives in Glamorgan, South Wales. Joan Abse, his wife, was an art historian and writer. Dannie Abse is well-known for being a poet and a medical doctor. Abse, in fact, was a specialist at a chest clinic for over thirty years. But Abse is best known for his writings and has received numerous literary awards and fellowships. In 1989, he received an honorary doctorate from the Universities of Wales.

The couple worked together editing two books in the 1980s.

Joan Abse leaves behind her husband, a son, and two daughters.

The world’s least expensive car, the Tata Nano, has been launched in India. It will go on sale in April, and will start delivery in July. The automobile costs only 100,000 Indian rupees, or just under US$2,000.

“We are at the gates offering a new form of transportation to the people of India, and later I hope other markets as well,” said the chairman of the auto firm, Ratan Tata, calling the vehicle a “milestone.”

“From the drawing board to its commercial launch, the car has overcome several challenges,” Tata said. “I hope it will provide safe, affordable four-wheel transportation to families who till now have not been able to own a car.

“This was never conceived as the cheapest car, but as providing transport to those people who never owned a car,” Tata said. “Driven mainly by the change in demand that we see elsewhere in the world, we suddenly felt we had a product that could be of considerable interest as a low-cost product in western Europe, eastern Europe, the UK and even the U.S.”

The Tata Nano is a four-door vehicle, and is 3 metres long, 1.5 m wide, and 1.5 m tall. It is equipped with a 33 bhp, 624 cc engine at the rear. No radio, airbags, power steering, or air conditioning are available in the basic model, although upgrades are available. The Nano Europa, a slightly larger European version of the car, is expected in 2011.

According to Ravi Kant, the managing director at Tata Motors, the first 100,000 people to receive a Nano would be chosen from the initial orders by a ballot.

An auto analyst for Bombay’s Angel Broking, Vaishali Jajoo, predicted that the Nano will add only three percent to Tata’s revenues even if it can sell a quarter of a million such cars per annum.

“That doesn’t make a significant difference to the top line,” Jajoo said. “And for the bottom line, it will take five to six years to break even.”

Environmentalists say that the car will exacerbate traffic problems already rife in India, and help increase pollution levels. Tata, however, stated that its vehicle is the least polluting car in the country.

Sweden’s first royal wedding since 1976 took place Saturday when Crown Princess Victoria, 32, married her long-time boyfriend and former personal trainer, Daniel Westling, 36. The ceremony took place at Stockholm Cathedral.

Over 1,200 guests, including many rulers, politicians, royals and other dignitaries from across the world, attended the wedding, which cost an estimated 20 million Swedish kronor. Victoria wore a wedding dress with five-metre long train designed by Pär Engsheden. She wore the same crown that her mother, Queen Silvia, wore on her wedding day 34 years previously, also on June 19. Victoria’s father, King Carl XVI Gustaf, walked Victoria down the aisle, which was deemed untraditional by many. In Sweden, the bride and groom usually walk down the aisle together, emphasising the country’s views on equality. Victoria met with Daniel half-way to the altar, where they exchanged brief kisses, and, to the sounds of the wedding march, made their way to the the silver altar. She was followed by ten bridesmaids. The couple both had tears in their eyes as they said their vows, and apart from fumbling when they exchanged rings, the ceremony went smoothly.

Following the ceremony, the couple headed a fast-paced procession through central Stockholm on a horse-drawn carriage, flanked by police and security. Up to 500,000 people are thought to have lined the streets. They then boarded the Vasaorden, the same royal barge Victoria’s parents used in their wedding, and traveled through Stockholm’s waters, accompanied by flyover of 18 fighter jets near the end of the procession. A wedding banquet followed in the in the Hall of State of the Royal Palace.

Controversy has surrounded the engagement and wedding between the Crown Princess and Westling, a “commoner”. Victoria met Westling as she was recovering from bulemia in 2002. He owned a chain of gymnasiums and was brought in to help bring Victoria back to full health. Westling was raised in a middle-class family in Ockelbo, in central Sweden. His father managed a social services centre, and his mother worked in a post office. When the relationship was made public, Westling was mocked as an outsider and the king was reportedly horrified at the thought of his daughter marrying a “commoner”, even though he did so when he married Silvia. Last year, Westling underwent transplant surgery for a congenital kidney disorder. The Swedish public have been assured that he will be able to have children and that his illness will not be passed on to his offspring.

Westling underwent years of training to prepare for his new role in the royal family, including lessons in etiquette, elocution, and multi-lingual small talk; and a makeover that saw his hair being cropped short, and his plain-looking glasses and clothes being replaced by designer-wear.

Upon marrying the Crown Princess, Westling took his wife’s ducal title and is granted the style “His Royal Highness”. He is now known as HRH Prince Daniel, Duke of Västergötland. He also has his own coat-of-arms and monogram. When Victoria assumes the throne and becomes Queen, Daniel will not become King, but assume a supportive role, similar to that of Prince Phillip, the husband of the United Kingdom’s Queen Elizabeth II.
