An anonymous reader writes "Financial markets experienced a series of computer glitches recently that brought operations to a halt. According to a researcher at the University of Miami, mobs of ultrafast robots, which trade and operate at speeds beyond human capability, may be responsible for these "flash freezes". From the article: '"Even though each trading algorithm/robot is out to gain a profit at the expense of any other, and hence act as a predator, any algorithm which is trading has a market impact and hence can become noticeable to other algorithms," said Neil Johnson, a professor of physics at the College of Arts and Sciences at the University of Miami (UM) and lead author of the new study. "So although they are all predators, some can then become the prey of other algorithms depending on the conditions. Just like animal predators can also fall prey to each other." When there's a normal combination of prey and predators, he says, everything is in balance. But once predators are introduced that are too fast, they create extreme events.'"Read Replies (0)

An anonymous reader writes "The New York Times reports, 'For eight decades, Manson Whitlock kept the 20th century's ambient music going: the ffft of the roller, the ding of the bell, the decisive zhoop ... bang of the carriage return, the companionable clack of the keys. From the early 1930s until shortly before his death last month at 96, Mr. Whitlock, at his shop in New Haven, cared for the instruments, acoustic and electric, on which that music was played. Mr. Whitlock was often described as America's oldest typewriter repairman. He was inarguably one of the country's longest-serving. Over time he fixed more than 300,000 machines, tending manuals lovingly, electrics grudgingly and computers never. "I don't even know what a computer is," Mr. Whitlock told The Yale Daily News, the student paper, in 2010. "I've heard about them a lot, but I don't own one, and I don't want one to own me."'"Read Replies (0)

Exxon has been charged with illegally dumping over 50,000 gallons of wastewater
at a shale-gas drilling site in Pennsylvania. From the article: 'Exxon unit XTO Energy Inc. discharged the water from waste tanks at the Marquandt well site in Lycoming County in 2010, according to a statement on the website of Pennsylvania’s attorney general
. The pollution was found during an unannounced visit by the state’s Department of Environmental Protection.
The inspectors discovered a plug removed from a tank, allowing the wastewater to run onto the ground, polluting a nearby stream. XTO was ordered to remove 3,000 tons of soil to clean up the area. Wastewater discharged from natural-gas wells can contain chlorides, barium, strontium and aluminum, the attorney general’s statement showed.
“Criminal charges are unwarranted and legally baseless,” the XTO unit said yesterday in a statement posted on its website. “There was no intentional, reckless or negligent misconduct by XTO.”'Read Replies (0)

An anonymous reader writes "The U.K.'s Guardian newspaper is reporting that the NSA shares the raw intel collected on Americans with Israel. From the article: 'Details of the intelligence-sharing agreement are laid out in a memorandum of understanding between the NSA and its Israeli counterpart that shows the U.S. government handed over intercepted communications likely to contain phone calls and emails of American citizens. The agreement places no legally binding limits on the use of the data by the Israelis. ... The deal was reached in principle in March 2009, according to the undated memorandum, which lays out the ground rules for the intelligence sharing. The five-page memorandum, termed an agreement between the U.S. and Israeli intelligence agencies "pertaining to the protection of U.S. persons," repeatedly stresses the constitutional rights of Americans to privacy and the need for Israeli intelligence staff to respect these rights. But this is undermined by the disclosure that Israel is allowed to receive "raw Sigint" – signal intelligence. The memorandum says: "Raw Sigint includes, but is not limited to, unevaluated and unminimized transcripts, gists, facsimiles, telex, voice and Digital Network Intelligence metadata and content."'Read Replies (0)
