Severe rainfall on the 16th of November has led to a water quality warning affecting more than two million people living in the Greater Vancouver metropolitan region. Wednesday’s storm triggered severe landslides in the region’s three water reservoirs, creating sediment levels up to ninety times higher than permitted under federal health standards. The Vancouver Coastal Health Authority issued a warning to residents advising them to boil all water intended for personal consumption. The advisory is mandatory for hospitals, daycares, and other public facilities, and is in effect until further notice.

The region’s Chief Medical Health Officer has advised that tap water not be used for anything. “We know that with turbidity levels this high there is an increased risk of gastrointestinal illness. So people need to be aware of that, although it’s their choice,” warned Dr. Patricia Daly. “If I’m asked, I’m telling the public: Don’t drink the water from the tap at this time. Drink bottled water or boil your water for a full minute.”

Commercial operations were affected as well. Food stores were ordered to turn off produce sprayers used to cool vegetables, and restaurants had to stop serving many food products. Many of Vancouver’s hundreds of coffee shops were quiet.

The Greater Vancouver area has received a total of 236.8mm of rain this month. The rainfall record of 350.8mm was set in 1983, according to measurements taken at Vancouver International Airport. BC Hydro, the province’s primary electrical provider, was busy repairing power and telephone lines blown down in the heavy winds. Over 220,000 customers were left without electricity in the aftermath of the storm, with more rain expected on Sunday.

A man has died after being involved in a robbery of his shop in West Yorkshire, England. Four youngsters, described as wearing hooded jumpers and tracksuit trousers, raided the Cowcliffe Convenience Store in the town of Huddersfield at approximately 2030 GMT on Saturday.

63-year-old Gurmail Singh sustained head injuries as a result of the robbery. Six witnesses attempted to prevent the youths from exiting the shop but failed, and the teenagers managed to escape with confectionary, cigarettes and money. One witness claimed to see a hammer in posession of one of the offenders, however it is unknown if this was used in the attack.

Singh was taken to Huddersfield Royal Infirmary but died there at approximately 0330 GMT on Sunday. West Yorkshire Police have now launched an investigation into the death of Gurmail Singh. A post-mortem examination is scheduled to take place on Monday to attempt to discover how the shop-owner was killed. West Yorkshire Police are now appealing for witnesses or anyone who has information in relation to this incident to contact them.

Thursday, June 1, 2006An attack against the Rashtriya Swayamsevak Sangh headquarters in Nagpur was thwarted by the Maharashtra police early today morning. The militants were driving a white Ambassador car and were armed with AK-47s. They were confronted and killed by security forces as they tried to break through the security cordon surrounding the building.

Nagpur Police Commissioner S.P.S Yadav said that the car was chased by police after it broke through the first barrier about 200 metres away from the headquarters. When confronted, the militants opened fire and were killed after a five-minute shootout. Yadav also said that two policemen had been injured in the incident, one of whose condition was serious. The identities of the three men is yet to be established. A diary was also recovered from the terrorists.

A high level security alert has been declared in Nagpur and other sensitive areas in the vicinity. R.S.S chief Ram Madhav urged the government to take more steps to safeguard the offices of the organisation. This is the second time the police has prevented a major terror attack from taking place in Maharashtra. Last month the Anti-Terrorist Squad had recovered 30 kilograms of RDX, 17 AK-47 rifles and 50 hand-grenades from a jeep in Aurangabad. Eleven suspected militants were also arrested.

Four people have been arrested on terrorism charges in Islington, London, England, after a suspected petrol bombing on the house of Martin Rynja, owner of book publishing company Gibson Square.

His company recently sparked controversy after buying the rights to publish The Jewel of Medina, a work of fiction by Sherry Jones depicting the Muslim prophet Muhammad and his child bride, Aisha.

The bombing, which occurred in the early hours of Saturday morning, led to the evacuation of the £2.5 million property in Lonsdale Square. Three men, aged 22, 30 and 40, were arrested at 2:25am BST by armed officers, two in Lonsdale Square, and one after being stopped near Angel tube station.

Police comments suggested that the trio had been under surveillance, and that they had advance knowledge of the plot and simply waited for the arsonists to strike, before arresting them.

On Saturday, a woman was arrested for obstructing police during their searches of four addresses – two in Walthamstow, and two in Ilford and Forest Gate.

Speaking earlier this month, Mr Rynja said that “The Jewel of Medina has become an important barometer of our time. As an independent publishing company, we feel strongly that we should not be afraid of the consequences of debate.” Ms Jones commented that she did not intend for her novel to be offensive to Islam. She noted that she “[has] deliberately and consciously written respectfully about Islam and Muhammad.” She “envisaged that [her] book would be a bridge builder” between Islam and the western world.

Last month Microsoft Corporation made accusations against the European Commission, stating that it may cause delays in the final release of their latest operating system, Windows Vista (formerly known as Longhorn).

Microsoft’s general counsel, Brad Smith, stated:

“We recognize that the European Commission does not give ‘green lights’ for new products, and we have not asked for one. We appreciate the constructive dialogue we have had with the Commission and the guidance the Commission has provided,” Smith added. Based on this guidance, we have made changes to ensure that we’re in compliance with our competition law obligations.“.

The news should be welcomed by all those anticipating Windows Vista within the European community, with Microsoft showing compliance to follow the regulations set out by the European Commission.

The entire debate started when Microsoft were responding to a letter received by the European Competition Commissioner, Neelie Kroes, that showed concerns over “The possible bundling into Vista of certain products, such as internet search and certain security features that are currently available on a standalone basis from Microsoft and other vendors“. In July, Smith had made a statement that Microsoft had offered to create changes to its system to comply with the commission, and that it had asked the commission to state which changes would make Vista apply to its standards and regulations.

“We told the Commission that we would be prepared to do any one of four things and they could simply tell us which of those things they wanted us to do” said Smith.

Since Bill Gates announced the removal of WinFS from its new operating system in October 2003, the company has been plagued by many setbacks and legal issues. Only time will tell whether Brad Smith’s announcement from Microsoft is entirely truthful instead of a way of covering Microsoft’s back.

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.

According to the United States Geological Survey (USGS) a magnitude 7.1 earthquake struck Alaska, United States, near the state’s most populous city of Anchorage. City authorities say they do not know of any injuries caused by the earthquake, which occurred early yesterday morning.

The earthquake’s epicentre was 162 miles (about 260 km) away from Anchorage, where residents reported feeling intense shaking. Associated Press reporter Mark Thiessen said he was woken from sleep by the quake, despite having taken sleeping pills earlier.

In the city of Kenai, gas explosions destroyed two homes. The quake destroyed four homes in total; the two other homes were damaged by fire, but did not explode. Authorities said around twenty people took shelter in a local armoury opened up for those whose homes were evacuated.

In Anchorage, utility companies reported small-scale power outages.

The quake was followed by two smaller quakes. Its focus was around 50 miles (80 km) underground, which, according to the National Weather Service, meant that the quake struck too deep to cause a tsunami.

240,000 U2] fans are preparing for Ireland’s most successful band ever to return for a hometown gig in Dublin. The supergroup is playing Friday, Saturday and Monday in front of 80,000 people a night at Croke Park. Gardaí have put in place a massive traffic management plan to cope with the influx of people. Fans have been queing since Thursday morning when a group of fans from Holland, Italy and Canada started queuing outside the stadium.

The concert forms part of U2’s current “Vertigo” world tour. The support acts include emerging Irish bands Snow Patrol and The Thrills along with already very popular Paddy Casey. Ash and The Bravery will cap it off as warm up acts on Monday.

The gates for the gig will open at 4pm with the actual band not expected until around 8.30pm. Irish media has entered a frenzied anticipation of the concert all this week, with constant coverage on radio stations. The national broadcaster, RTÉ, is set to dedicated almost 3hr 30min to the band with an exclusive interview by Dave Fanning forming the centerpiece of the stations coverage of the “U2 weekend”. Coldplay frontman Chris Martin, who played in front of a sell out crowd in Dublin earlier this week told fans that U2 were “still the best band in the world”.

Croke Park is the fourth largest stadium in Europe, with an official capacity of 82,000 – bigger than both Cardiff’s Millennium Stadium and Paris’ Stade de France. Croke Park is used to host GAA matches in sports such as hurling and Gaelic football and regularly attracts audiences of 60,000 or more in the summer months.
