The 10.10 version of Ubuntu (codename Maverick Merkaat), a free operative system is to be released in the next few days. French Wikinews contributor Savant-fou (Baptiste) has interviewed Fabrice (fabrice_sp on Ubuntu), an Ubuntu’s MOTU (Master Of The Universe), member of the development team of the operative system.

Ubuntu is a computer operating system, based on Debian, which is created collaboratively by thousands of people. There are three official Ubuntu versions: Ubuntu Desktop Edition (for desktop and laptop PCs); Ubuntu Netbook Edition (for netbooks); and Ubuntu Server Edition (for use in servers).

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.

India is the latest of the countries where the One Laptop Per Child (OLPC) experiment has started. Children from the village of Khairat were given the opportunity to learn how to use the XO laptop. During the last year XO was distributed to children from Arahuay in Peru, Ban Samkha in Thailand, Cardal in Uruguay and Galadima in Nigeria. The OLPC team are, in their reports on the startup of the trials, delighted with how the laptop has improved access to information and ability to carry out educational activities. Thailand’s The Nation has praised the project, describing the children as “enthusiastic” and keen to attend school with their laptops.

Recent good news for the project sees Uruguay having ordered 100,000 of the machines which are to be given to children aged six to twelve. Should all go according to plan a further 300,000 machines will be purchased by 2009 to give one to every child in the country. As the first to order, Uruguay chose the OLPC XO laptop over its rival from Intel, the Classmate PC. In parallel with the delivery of the laptops network connectivity will be provided to schools involved in the project.

The remainder of this article is based on Carla G. Munroy’s Khairat Chronicle, which is available from the OLPC Wiki. Additional sources are listed at the end.

Buffalo, New York — In an unanimous vote, the City of Buffalo‘s Planning Board voted to table the Elmwood Village hotel Proposal, postponing voting on legislation for up to 30 days.

The Board said its decision was due to the lack of public involvement, saying that there have not been enough meetings.

The Elmwood Village Hotel is a proposed project by Savarino Construction Services Corporation and was designed by Karl Frizlen of The Frizlen Group. The hotel would be placed on Elmwood and Forest Avenues in Buffalo, New York. In order for the hotel to be built, at least five buildings, that include both businesses and residents, must be demolished.

The Forever Elmwood Corp. is a Buffalo-based non-profit organization founded in 1994. Justin Azzarella, the Executive Director for the organization voiced support for the proposal, stating: “I am here today to lend Forever Elmwood’s support the hotel project. Particularly, Forever Elmwood is encouraged by the fact that this building follows the more stringent Elmwood Village Design Guidelines. We have been speaking with Savarino Construction, and they have promised us [Forever Elmwood] that they will engage the community further, including the surrounding Block Clubs and businesses. For that reason, while Forever Elmwood is in support of this project and the type of project that it is, we are asking also that the project be tabled so that the community can be further engaged. Specifically the surrounding Block clubs which include the Granger, Claremont, Asland and The Lincoln Parkway Block Clubs.”

“Because of the excellent work that Karl does and the game plan that they have, I think its an ideal use of this particular location. I think that this particular type of development needs to be encouraged and promoted as opposed to roadblocked,” said a man who owns five properties near the proposal site.

However, Evelyn Bencinich, a resident of Granger Place and whose house would be located directly behind the hotel said, “My property value will be depreciated or non-existent because no one is going to want to live behind a multi-story hotel. We are facing up to a year of noisy and dangerous demolition and construction. Children, pets and even drunk rebellers could wander on site and get hurt. Traffic tie-ups caused by large machinery and garbage bins is inevitable. Where will pedestrians walk? We could experience increased unsanitary flooding in our yards and basements due to the digging and cementing for the underground parking garage. Rats will be displaced into the immediate neighborhoods and be in great abundance. Once we get past the year of nightmare construction, what if you build it and they don’t come? We could ultimately have a seven million dollar rooming house on our corner.”

Patty Morris, co-owner of Don Apparel with Nancy Pollina at 1119 Elmwood also asked that the project be tabled saying, “this has only been public knowledge for less than two weeks and the public never saw the redesign. How can you vote on anything that no one has seen yet? The Board cut off Morris saying, “so specifically you don’t have any problem with it [the design] you just…” Morris then said, “Oh I am totally against this project, but thats besides the point isn’t it.”

The planning board is also concerned that the current design may still be too big.

At one point Board member Susan Curran Hoyt said, “we know you’ve cut down your number of rooms on this project, but we still see it doesn’t seem to fit the description of a ‘botique’ hotel,” and asked Eva Hassett, Vice President of Savarino Construction, “we wonder if you could reduce the rooms further.”

“One thing I didn’t talk about was the price levels of these rooms and that will be important to know. The room rate will be somewhere between US$120 and $160 a night, which is about the same price of the Hampton Inn down town and the smaller you make the hotel, the more expensive the rooms will get. We believe that we’ve made a good compromise in terms of the size of the hotel and perhaps botique means different things to different people,” said Hassett.

The board was also concerned that there is not enough parking asking, “are there alternative plans for valet parking off-site, in the event that you have a full hotel or a large event going on?”

“We are exploring several possibilities with respect to additional parking for valet and parking near-by,” replied Hassett. “We are also exploring the possibility of using the rear of 1105 Elmwood for additional parking, which would give us an additional ten or eleven spaces.”

The new design has a total of 55 parking spaces for 72 rooms, with 39 of them underground and the rest on ground level.

Hassett also said that a “parking study” will be done on the area.

Concerns that the second floor of the hotel will be too close to the property of 605 Forest were also brought up. The board asked how far the hotel would be from the property and Karl Frizlen replied saying it would “be approximately five feet from the property line,” but he also admitted that, “I do not know exactly how close the house next door” will be from the hotel, but did say “I think the house is about four or five feet away from the property line and we [the hotel] sit right on the property line.”

The board is concerned the setback from the property is not enough saying the space between the building and the hotel is “pretty narrow.”

The City’s Common Council also agreed to table the proposal also citing the need for more public engagement and the need for more organizations to respond including the Buffalo Preservation Board and the Office of Historic Preservation.

During that meeting, Hassett also said the proposal to try and get a variance to obtain the properties of 605 and 607 Forest were “now off the agenda.”

The Common Council is expected to meet and hold a public hearing about the project and the rezoning of the properties to be demolished (1119-1121 Elmwood) on Tuesday March 7, 2006 at 2:00 p.m. in Council Chambers at City Hall. At the moment the properties are not zoned for a hotel.

The Service Employees International Union, a trade union in the United States and Canada, was trying to unionize 8,300 workers in nine different Ohio hospitals through elections that were scheduled for this Wednesday and Friday. But then organizers from a second union, the California Nurses Association, visited the hospitals to encourage the workers to vote not to join the S.E.I.U. These actions led to the service employees union on Tuesday asking to postpone the vote by workers at the nine hospitals, all which are a part of the Catholic Healthcare Partners system.

Andy Stern, the service president is quoted as saying, “nothing more than a flimsy cover for out-and-out union busting that we normally see from employers, not organizations that claim to care about workers.”

The California Nurses Association, said it dispatched organizers to Ohio because in its view the unionization efforts were part of a “sweetheart deal”.

Rose Ann DeMoro, executive director of the nurses association, condemned this agreement. She called it “a rigged scam” in which the service union would bargain without care if they won the vote.

“This was a top-down deal between an employer and a hand-picked union,” Ms. DeMoro said. “There was a gag order on everyone, and as a result this was a banana republic election.”

“As for the future,” DeMoro said, “no election is planned.” She said that delaying the election was “a significant victory for employee rights.”

Dave Regan, president of a service employees’ local representing 35,000 health care workers in Ohio, West Virginia and Kentucky, called the nurses union’s conduct as, “Their conduct is indistinguishable from that of the most vicious anti-union employers,” Mr. Regan said. “It violates every principle of unionism. Real people are worse off today as a result of their behavior.”

Orest Holubec, spokesman for Catholic Healthcare, said the system’s hospital in Lima had obtained a restraining order to bar the California nurses from entering restricted patient-care areas and aggressive leafletting outside hospitals. “They were doing exactly the kind of things we were trying to avoid,” Mr. Holubec said. “They poisoned the well to the degree that we didn’t have the conditions that we tried to establish for a pressure-free environment.”

MV Suilven, a ferry in service in Fiji, capsized and sank in Suva Harbour today.

Around thirty people, all crewmembers, were on board. Local media report all were rescued. The 41-year-old vessel previously saw service in Scotland and New Zealand.

The ship capsized early this afternoon and sank within an hour. It had been converted from passenger to cargo use following its most recent sale, to Venu Shipping in 2012 or 2011. Local reports indicated police, the Navy, local tug boats, and volunteer rescuers all attended the accident.

The converted ferry reportedly began to list on entering the harbour. It was working a route carrying cargo between Suva and the Northern Division.

Built in Norway, in service from 1974, the ship served with Scottish ferry firm Caledonian MacBrayne until 1995, connecting the mainland town of Ullapool to Stornoway on the Isle of Lewis. It was ultimately replaced by a larger, faster vessel and was sold to Strait Shipping who used it until 2004 to ply New Zealand’s seas, connecting Wellington to Picton and to Nelson.

The name MV Suilven is in reference to the Suilven mountain in Scotland’s Sutherland region.

Friday, November 7, 2014 Albuquerque, New Mexico — Online entertainment is a booming market, and plenty of players are making their play; back in March of this year The Walt Disney Company bought the multi-channel network Maker Studios. What is web entertainment, and the arts therein? And, who are the people venturing into this field? Wikinews interviewed Mario Lucero and Isabel Ruiz, the founders of Heaven Sent Gaming, a small entertainment team. This group has been responsible for several publications, within several different media formats; one successful example was aywv, a gaming news website, which was #1 in Gaming on YouTube in 2009, from September to November; Heaven Sent Gaming was also the subject of a referential book, released in 2014, entitled Internet Legends – Heaven Sent Gaming.
