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.

On Tuesday many internet routers, used to find the pathways to different parts of the web, reached their memory limit of 512,000 entries in the tables they use to store the routes, causing problems for many users.

A router is used to direct a user towards the area of the internet where they will find the content they are looking for, e.g. a web page. The recent problem was caused by the arbitrary memory limit built into the design of many aging routers. A limit was needed to prevent the cost of hardware from becoming prohibitively expensive in the days when physical data storage was still comparatively expensive. This small amount of memory in turn limits the number of directions which can be stored on a single router leading to different parts of the internet. When this limit was reached, it caused outages of services among Internet Service Providers. Many routers, including older ones provided by Cisco Systems Inc., are limited to storing a total of 512,000 routes or paths.

This limit was reached on Tuesday, reported to have been triggered by Verizon publishing another 15,000 paths. Those affected included eBay, LastPass, and clients of the web hosting company Liquid Web, who lost much of their services until Verizon withdrew some of these new paths. Problems nevertheless continued throughout the day, even after the withdrawal.

A longer term fix is possible, but it would require manually replacing old routers with newer, more capable ones. It is hard to tell what issues would temporarily cascade though the internet by taking down routers from part of the internet for maintenance. Many experts have warned that problems could continue until these difficult fixes have been implemented, although the recent switch to a newer form of IP Addresses, IPv6, will temporarily help the issue. Wired News reported that Andre Toonk, a network engineer, had stated that the number of network outages on the internet, typically around 1,500, yesterday peaked at 2,587, enough to become clearly noticeable.

They are cheap, useful, and very plentiful, and that is exactly the problem, according to researchers. A report issued on Feb. 23 by a cadre of environment and economics researchers suggested that Kenya should ban the common plastic bag that one gets at the checkout counter of grocery stores, and place a levy on other plastic bags, all to combat the country’s environmental problems stemming from the bags’ popularity.

A woman attacked Pope Benedict XVI during Christmas Eve Mass at St. Peter’s Basilica in Vatican City, causing a disruption to the ceremonies. The pope was unharmed and got to his feet and completed the Mass, although afterwards he was taken to a local hospital for evaluation. French Cardinal Roger Etchegaray also fell down and broke a leg. The accused assailant, Susanna Maiolo, is a 25-year-old Swiss national from the Ticino region, is reported to have psychiatric problems.

Susanna Maiolo also attempted to attack the pope during last years Midnight Mass, although she was stopped by security. During both assaults it appears that she was wearing the same red sweater. Vatican spokesman, Rev Federico Lombardi said that “She is known to the Vatican but she was never thought to have been of any serious danger to the Holy Father.”

Despite the attack the pontiff decided to continue the midnight mass services. Although noticeably shaken, he still delivered the traditional “Urbi et Orbi” speech. In this years speech he mentioned the current financial crisis, conflicts in Africa and Israel, and the state of the Christian minority in Iraq.

The nuclear reactor at Chalk River, Ontario in Canada was shut down on Thursday, May 14 by the Atomic Energy of Canada Limited (AECL) due to a leak of heavy water. Government officials say that by Saturday the demand for medical isotopes will no longer be met, due to the shortage caused by the closure.

Medical isotopes are used in diagnostic procedures for cancer, heart disease and other medical conditions. When radioactive isotopes are injected into the body, radiologists can view higher radiation via medical imaging, enabling them to make a more accurate diagnosis.

Estimates suggest that the reactor will be shut down for approximately one month for repairs. The Chalk River Laboratories produce 33% of the international supply of medical isotopes.

Lisa Raitt, Natural Resources Minister said, “A secure supply of medical isotopes is not only an issue for Canada, it is an international issue that is being addressed co-operatively by all isotope-producing countries.”

“It may mean that if you have an elective study booked … that patient is going to be deferred and will have to wait until the situation is resolved. I’m reasonably confident that for most patients, if they’re having an acute problem, that problem is going to be dealt with – and the greater the acuity, the more likelihood it’s going to be dealt with quickly and expeditiously,” said Dr. Karen Gulenchyn, a nuclear medicine expert.

“The government of Canada is engaging international isotope producers as well as companies such as MDS Nordion, Lantheus, and Covidien, who all play key roles in securing medical isotope supply for North America,” said Raitt and Health Minister Leona Aglukkaq.

In December 2007, the 52-year-old reactor was shut down and the Canadian House of Common stepped in to restart the reactor.

Venezuela’s government has opened a granite processing plant in the state of Bolívar, with the intention of providing about 25% of the granite required nationwide.

Ricardo Menéndez, vice president of the Productive Economic Area, said Venezuelan President Hugo Chávez has yearned for the creation of this project to empower Venezuelan construction. Granito Bolívar is reportedly the most modern Venezuelan granite plant, not consuming community water or electricity, and is also the largest, with a daily capacity to supply enough material for use in construction of about 820 houses.

Menéndez said, “These granite blocks are the natural resources of our country, are the wealth we have as a country and often [some] simply decided to remove this richness from our country and take them to other countries” ^{((es))Spanish language: ?Esos bloques de granito son la riquezas naturales de nuestro país, son las riquezas que tenemos como patria y que muchas veces sencillamente esas riquezas decidieron sacarlas de nuestro territorio nacional y llevarlas a otros países}.

According to Menéndez, with the help of a state plan, Venezuela intends to exploit its 40,000 million cubic meters or more of granite reserves, generating a set of factories. “[T]he central theme is that these plants, all these factories, are for the construction of socialism; that means using our potential, develop the value chain within the country and of course that yields benefits from the point of view of the production system’s organization…. [Granito] Bolívar is not only the vision that historically we had of exposing richness, but the industries, basic industries we have, that level of our workers in the basic industries and in addition the development of the potential we have in the state” ^{((es))Spanish language: ?el tema central es que estas plantas todas estas fábricas son para la construcción del socialismo, eso significa utilizar nuestras potencialidades, dessarrollar la cadena de valor dentro del país y por supuesto que eso genere beneficios desde el punto de vista de la organización del sistema productivo … Bolívar no solamente es la visión que históricamente se tuvo de exponer las riquezas, sino que son las empresas, las empresas básicas que tenemos, ese nivel de nuestros trabajadores de la empresas básicas y adicionalmente el desarrollo del potencial que tenemos en el estado}.

For the construction of the plant, supplied by 23 quarries, the government of Bolívar provided about 30 million bolívares (US$4.7 million) and the national government €2.3 million (US$3 million). Bolívar reportedly has reserves of about 40,000 million tons of red, black, pink and white granite, sufficient for domestic demand for 200 years.

Tuesday, April 5, 2005Terry Vo, the 10-year old Australian boy who had two hands and a foot reattached by surgeons after losing them in an accident, has had to have the foot re-amputated. He will be given a prosthetic foot in its place.

The operation to re-attach three limbs was thought to have been a first – but was ultimately unsuccessful, with the foot having died inside, and receiving insufficient blood supply following the surgery to reattach it.

“That would lead to the small muscles in the foot actually constricting, the toes bending over and a deformed …. foot that is sort of clawed over and doesn’t have good sensation,” said plastic surgeon, Mr Robert Love today, on Australia’s ABC Radio.

“Even if you can get all of that to survive, he [would be] worse off than having had an amputation.”

“What is very disappointing is that for the first two days after [the operation] the foot looked absolutely magnificent,” he said.

Terry’s hands were healing well, said the surgeon. The prosthetic foot would allow him to walk normally, since his knee was intact.
