Year 2038 problem

The year 2038 problem (also known as “Unix Millennium bug”, or “Y2K38” by analogy to the Y2K problem) may cause some computer software to fail before or in the year 2038. The problem affects all software and systems that store system time as a signed 32-bit integer, and interpret this number as the number of seconds since 00:00:00 January 1, 1970.[1] The latest time that can be represented this way is 03:14:07 UTC on Tuesday, 19 January 2038. Times beyond this moment will “wrap around” and be stored internally as a negative number, which these systems will interpret as a date in 1901 rather than 2038. This will likely cause problems for users of these systems due to erroneous calculations.

Most 32-bit Unix-like systems store and manipulate time in this format, so this problem is often referred to as the “Unix Millennium Bug”. However, any other non-Unix operating systems and software that store and manipulate time this way will be just as affected by this problem.

Astronomers find water in another galaxy

The water vapor was found 11.5 billion light years from Earth, using the 100-meter Effelsberg radio telescope at the Max Planck Institute for Radio Astronomy in Leipzig, Germany.

Violette Impellizzeri, formerly of the Max Planck Institute and now with the National Radio Observatory in Virginia, led the investigation of the ancient water disc. She says the existence of water in a galaxy that is close to the 13-billion-year-old age of the Universe is not unexpected, but it is the first time it has been shown.

“This is also a result by itself, that we were able to find a molecule [water] seemed to have produced after a very short time after the Big Bang,” she said. “I mean the Universe is young and already there is already a high abundance of molecules.”

The study on the discovery of ancient water in the Universe is published in the journal Nature.

Colossal refrigeration system

Ron Ace, a 69-year-old, has been researching the earth’s climate for years and has found what he calls the most “practical, nontoxic, affordable, rapidly achievable” and beneficial way to curb global warming and a resulting catastrophic ocean rise.

Ace proposes to spray gigatons of sea-water into the air and in effect, build a “a colossal refrigeration system with a 100,000-fold performance multiplier.” He contends a number of positive effects would be in action at the same time to help stave off warming.

“The Earth has a giant air-conditioning problem,” he said. “I’m proposing to put a thermostat on the planet.”

New Source of Biodiesel

Researchers in Nevada are reporting that waste coffee grounds can provide a cheap, abundant, and environmentally friendly source of biodiesel fuel for powering cars and trucks. Their study has been published online in the Journal of Agricultural and Food Chemistry. Growers produce more than 16 billion pounds of coffee around the world each year. Scientists estimate that spent coffee grounds can potentially add 340 million gallons of biodiesel to the world’s fuel supply.

Biodiesel is a growing market. Estimates suggest that annual global production of biodiesel will hit the 3 billion gallon mark by 2010. The fuel can be made from soybean oil, palm oil, peanut oil, and other vegetable oils; animal fat; and even cooking oil recycled from restaurant French fry makers. Biodiesel also can be added to regular diesel fuel. It also can be a stand-alone fuel, used by itself as an alternative fuel for diesel engines.

Electric Car Network

Zero-emission vehicles, alternative fuels, independence from foreign oil supplies, and low carbon footprints are more than just pie-in-the-sky wishes–they can also be big business. Following in the steps of San Francisco, San Jose, and Oakland, Better Place has just entered into an agreement with the state of Hawaii and the Hawaiian Electric Companies to implement a statewide electric-car charging network throughout Hawaii.

Augusta Ada Lovelace

Her full name and title for most of her married life was “The Right Honourable Augusta Ada, Countess of Lovelace”, born Augusta Ada Byron, was the only legitimate child of Lord Byron. She is widely known in modern times simply as Ada Lovelace.

She is today appreciated as the “first programmer of the history”.

The computer language Ada, created by the U.S. Defense Department, was named after Lovelace. The reference manual for the language was approved on 10 December 1980, The Department of Defense Military Standard for the language, “MIL-STD-1815” was given the number of the year of her birth. In addition Lovelace’s image can be seen on the Microsoft product authenticity hologram stickers.

Charles Babbage

Charles Babbage, FRS (December 26, 1791 London, England – October 18, 1871 Marylebone, London, England)[2] was an English mathematician, philosopher, inventor and mechanical engineer who originated the concept of a programmable computer. Parts of his uncompleted mechanisms are on display in the London Science Museum. In 1991 a perfectly functioning difference engine was constructed from Babbage’s original plans. Built to tolerances achievable in the 19th century, the success of the finished engine indicated that Babbage’s machine would have worked. Nine years later, the Science Museum completed the printer Babbage had designed for the difference engine, an astonishingly complex device for the 19th century. Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs.

Declaration of Human Rights

To mark the 60th anniversary of the UDHR, a copy of the historic document will be hand-delivered and placed on board the European Space Agency’s Columbus module. The UDHR will remain on board the science laboratory permanently as a testament to the people on Earth and the astronauts in space who live by these rules. All going well, November 14th will see the launch of STS-126, Space Shuttle Endeavour’s resupply mission to the ISS. The seven-member crew is set to deliver equipment to the ISS as well as repair the Solar Alpha Rotary Joints (SARJ). However, Endeavour will also have some extra special cargo on board.

The ESA Astronaut Corps welcomes this humanitarian initiative. In recognition of the fact that human beings are at times downtrodden, the Declaration can symbolically find its place ‘above’ all the peoples of the world,” said ESA astronaut Léopold Eyharts, who helped to install the Columbus module back in February.

The Video Game Museum

The UK’s first official national video game archive has been launched in a bid to preserve the history of gaming.

The archive has been set up in partnership between Nottingham Trent University and the National Media Museum in Bradford in the north of England.

“We are going to be archiving video games but it’s not just about the games themselves, it’s also about gaming culture,” said James Newman, from Nottingham Trent University’s Centre for Contemporary Play, a research group dedicated to video games.

“We absolutely want to put the original hardware and software into the hands of players who haven’t seen this stuff”.

The collection will be officially opened at the GameCity Festival in Nottingham on 30 October.

Interplanetary Internet

In an initiative energized by Google Vice-President and Chief Internet Evangelist Vint Cerf, the International Space Station could be testing a brand new way of communicating with Earth. In 2009, it is hoped that the ISS will play host to an Interplanetary Internet prototype that could standardize communications between Earth and space, possibly replacing point-to-point single use radio systems customized for each individual space mission since the beginning of the Space Age.
