On Tuesday, German Chancellor Olaf Scholz met with the Russian President Vladimir Putin in Moscow. The main agenda was the ongoing crisis near the Russian-Ukrainian border. On Monday, Scholz had visited Kiev, where he met with Ukrainian President Volodymyr Zelensky and showed support to Ukraine against the Russian position.

After Tuesday’s meeting, a joint press conference was held, in which Scholz said, “it is our absolute duty as heads of government that Europe does not see an escalation into war.” When asked about the deployments and the threat of war, Putin said Russia does “not want war in Europe.” He later added Russia is “ready to work further together” and “go down the negotiations track”.

However, Putin called Russia’s claims valid and described the situation in Ukraine’s Donbas region as a ‘genocide’. On Tuesday, the Russian Defence Ministry declared it had begun to pull back some of its troops and called the deployments a ‘military drill’.

The German Chancellor said the withdrawal of some troops was a good sign. On the other hand, Ukraine’s Foreign Minister Dmytro Kuleba said they wouldn’t accept any claims by Russia until they see it themselves and added “if we see a withdrawal, we will believe in a de-escalation”. NATO Secretary General Jens Stoltenberg welcomed Russia’s response of a diplomatic solution but said it had not seen ‘any sign of de-escalation on the ground’ yet.

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.

Last month, a study conducted by archæologist Dr. Naomi Martisius and other researchers concluded Neanderthals living in Europe tens of thousands of years ago were more sophisticated than previously thought. The now-extinct species used to carefully select bones from a particular animal species to manufacture their bone tools, the research showed. The research was published on May 8 in Nature’s Scientific Reports journal.

Dr Martisius and her team used five bone tools discovered from Neanderthals’ sites in southwest France for this research. Four of these bone tools were found in a site called Abri Peyrony and the other one was from Pech-de-l’Azé I. These tools were just a few centimetres in size and were about 50 thousand years old, Dr Martisius told Wikinews. Microscopy analysis of these bone tools called lissoirs (smoothers) suggested Neanderthals used these tools for working animal skin to leathers.

The study stated the fauna of the sites were primarily medium-sized ungulates such as reindeer, in one layer nearly 90%. Despite the overabundance of medium-sized ungulates, Neanderthals used ribs of large bovids for making lissoirs. Dr Martisius told Wikinews this was likely due to the physical characteristics of the bovid ribs, which were “thicker” and “stronger” as compared to the “thin and flimsy ribs” of reindeers. In order to check the origins of the bone tools, the researchers used a technology called non-destructive Zooarchæology by Mass Spectrometry (ZooMS).

Instead of damaging the bone artefacts in order to discover its origins, the researchers collected collagen from the plastic containers in which these artefacts were kept. Collagen is a type of protein. These bone artefacts were kept in plastic containers: some were kept for about five years, some for just a few months. During this time, the collagen proteins from bone tools were stuck to the walls of its plastic containers. The collagen samples collected from the walls of the containers are broken into smaller molecules called peptides by using a chemical enzyme called trypsin.

After the trypsin has broken collagen fibres into peptides, it is analysed using a technology called Matrix-assisted laser desorption/ionization (MALDI) Time-of-Flight mass spectrometer (ToF MS). The assisting matrix is a coloured compound. The acidic peptide is combined with the matrix, vapourised, and peptides are released. Some of them are positively-charged particles which travel across a vacuum tube in an electric field. Depending on the weight of the peptides, these molecules reach the end of the vacuum tube at different instances of time, forming a spectrum. These graphs are like unique fingerprints of a species: they are different for different species of animals. Looking at the database of such graphs, taxonomic identifications of the collagen proteins came be made.

All four bone tools from Abri Peyrony gave positive results and showed that the bones were made from large bovids, even though reindeer were more abundant during that time. One of the advantages of using bovid ribs over reindeer’s thin ribs was the bovid ribs would be more resistant to breaking during flexion, Dr Martisius said.

Dr Martisius said such non-destructive ZooMS analysis was previously conducted, but for tools no older than a few centuries. She said such an analysis had never been previously conducted for artefacts so ancient.

Wikinews caught up with Dr Martisius to discuss this research in-depth.

Today the New Zealand Finance Minister, Hon. Dr Michael Cullen, presented the 2006 New Zealand Budget to the House of Representatives. There is a NZ$8.5 billion OBERAC surplus and a NZ$1.5 billion cash surplus.

It has been labelled as the “Bondi Budget” by National leader Don Brash, “Helen Clark and Michael Cullen believe there is a place for tax cuts – it’s called Australia” he said.

The budget allocates new operating spending of $9.6 billion and capital of $2.7 billion over the next four years.

Key issues in the budget includes:

• The Telecom New Zealand local loop unbundling (released earlier due to leak).
• $1.3 billion extra for transport.
• $3 billion extra for health care, over the next four years.
• $361 million extra for schooling
• $166 million extra for tertiary education and skill training
• $162 million extra for early childhood education

It has emerged that the 33 Chilean miners trapped underground after the mine they were working in collapsed could be brought to the surface in a shorter time than was initially feared. While officials publicly announced that the men would not be brought to the surface until Christmas, sources inside technical meetings have revealed that they could in fact be on the surface by early November. The news comes as families were allowed to speak by radio-telephone to their trapped loved ones on Sunday. Over the weekend, video images filmed by the miners emerged showing the miners playing dominoes at a table and singing the Chilean national anthem. The miners also used the camera to send video messages to their families on the surface, saying that they regularly broke into tears, but were feeling better having received food and water.

The grainy nightvision images, filmed on a high definition camcorder that was sent down a small shaft to the mine, show the men in good spirits, chanting “long live Chile, and long live the miners.” They are unshaven and stripped to the waist because of the heat underground, and are seen wearing white clinical trousers that have been designed to keep them dry. Giving a guided tour of the area they are occupying, Mario Sepúlveda, one of the miners, explains they have a “little cup to brush our teeth”, and a place where they pray each day. “We have everything organized,” he tells the camera. Gesturing to the table in the center of the room, he says that “we meet here every day. We plan, we have assemblies here every day so that all the decisions we make are based on the thoughts of all 33.” Another unidentified miner asks to rescuers, “get us out of here soon, please.” A thermometer is shown in the video, reading 29.5C (85F).

As the film continues, it becomes evident that the miners have stuck a poster of a topless woman on the wall. The miners appear shy, and one man puts his hand to his face, presumably dazzled by the light mounted on the cameraman’s helmet. One miner sent a message to his family. “Be calm”, he says. “We’re going to get out of here. And we thank you from the bottom of our hearts for your efforts.” Another said that the miners are “sure that there are people here in Chile that are big people, that are powerful people, that are intelligent people, and they have the technology and they will all work together to get us out of here.” Speaking to the camera, one says: “we have had the great fortune that trapped in this mine there are good, professional people. We have electricians, we have mechanics, we have machine operators and we will let you know that while you are working to rescue us on the surface, we are down here ready to help you too.” It has been reported that Mario Gómez, 63, has become the group’s “spiritual leader”, having worked in the mines for over fifty years. He has requested that materials to build a shrine be sent down to the cavern.

Upon seeing the video in a private screening, family members, who are living in a small village of tents at the entrance to the San José copper-gold mine—which they have named Camp Hope—were elated. “He’s skinny, bearded and it was painful to see him with his head hanging down, but I am so happy to see him alive”, said Ruth Contreras, the mother of Carlos Bravo, who is trapped in the mine. The video, of which only a small portion has been released to the public, shows the miners, many of them wearing helmets, cracking jokes and thanking the rescuers for their continued efforts. The supplies are being sent to the men through a small shaft only twelve centimeters wide, and a laboratory has been set up with the purpose of designing collapsible cots and miniature sandwiches, which can be sent down such a narrow space.

CNN reported on Friday that “officials are splitting the men into two shifts so one group sleeps while the other works or has leisure time .. On average, each man has lost 22 pounds (10 kilograms) since they became trapped three weeks ago, and dehydration remains a threat. But a survey of the men indicates that at least nine miners are still too overweight to fit through the proposed rescue shaft. Initially, the miners survived by draining water from a water-cooled piece of equipment. To stay hydrated in the 90-degree mine, each miner must drink eight or nine pints of water per day.”

But while there are jubilant celebrations on the surface that the miners are alive, officials are now nervous that the miners could become depressed, trapped in a dark room the size of a small apartment. Chilean health minister Jaime Mañalich said that, on the video, he saw the telltale signs of depression. “They are more isolated, they don’t want to be on the screen, they are not eating well”, he said. “I would say depression is the correct word.” He said that doctors who had watched the video had observed the men suffering from “severe dermatological problems.” Dr. Rodrigo Figueroa, head of the trauma, stress and disaster unit at the Catholic University in Santiago, Chile, explained that “following the euphoria of being discovered, the normal psychological reaction would be for the men to collapse in a combination of fatigue and stress … People who are trained for emergencies – like these miners – tend to minimize their own needs or to ignore them. When it is time to ask for help, they don’t.” NASA has advised emergency workers that entertaining the miners would be a good idea. They are to be sent a television system complete with taped football matches. Another dilemma facing Mañalich is whether the miners should be permitted to smoke underground. While nicotine gum has been delivered to the miners, sending down cigarettes is a plan that has not been ruled out.

With the news that drilling of the main rescue tunnel was expected to begin on Monday, officials have informed the media that they hope to have the miners out of the mine by Christmas—but sources with access to technical meetings have suggested that the miners could actually be rescued by the first week of November. A news report described the rescue plan—”the main focus is a machine that bores straight down to 688m and creates a chimney-type duct that could be used to haul the miners out one by one in a rescue basket. A second drilling operation will attempt to intercept a mining tunnel at a depth of roughly 350m. The miners would then have to make their way through several miles of dark, muddy tunnels and meet the rescue drill at roughly the halfway point of their current depth of 688m.” Iván Viveros Aranas, a Chilean policeman working at Camp Hope, told reporters that Chile “has shown a unity regardless of religion or social class. You see people arriving here just to volunteer, they have no relation at all to these families.”

But over the weekend, The New York Times reported that the “miners who have astonished the world with their discipline a half-mile underground will have to aid their own escape — clearing 3,000 to 4,000 tons of rock that will fall as the rescue hole is drilled, the engineer in charge of drilling said Sunday … The work will require about a half-dozen men working in shifts 24 hours a day.” Andrés Sougarret, a senior engineer involved in operating the drill said that “the miners are going to have to take out all that material as it falls.”

The families of those trapped were allowed to speak to them by radio-telephone on Sunday—a possibility that brought reassurance both the miners and those on the surface. The Intendant of the Atacama Region, Ximena Matas, said that there had been “moments of great emotion.” She continued to say that the families “listened with great interest and they both felt and realized that the men are well. This has been a very important moment, which no doubt strengthens their [the miners’] morale.” The phone line is thought to be quite temperamental, but it is hoped that soon, those in the mine and those in Camp Hope will be able to talk every day. “To hear his voice was a balm to my heart … He is aware that the rescue is not going to happen today, that it will take some time. He asked us to stay calm as everything is going to be OK … He sounded relaxed and since it was so short I didn’t manage to ask anything. Twenty seconds was nothing”, said said Jessica Cortés, who spoke to her husband Víctor Zamora, who was not even a miner, but a vehicle mechanic. “He went in that day because a vehicle had broken down inside the mine … At first they told us he had been crushed [to death].”

Esteban Rojas sent up a letter from inside the mine, proposing to his long-time partner Jessica Yáñez, 43. While they have officially been married for 25 years, their wedding was a civil service—but Rojas has now promised to have a church ceremony which is customary in Chile. “Please keep praying that we get out of this alive. And when I do get out, we will buy a dress and get married,” the letter read. Yáñez told a newspaper that she thought he was never going to ask her. “We have talked about it before, but he never asked me … He knows that however long it takes, I’ll wait for him, because with him I’ve been through good and bad.”
