KentuckyFC writes "Warp drives were generally considered impossible by mainstream scientists until 1994 when the physicist Michael Alcubierre worked out how to build a faster-than-light drive using the principles of general relativity. His thinking was that while relativity prevents faster-than-light travel relative to the fabric of spacetime, it places no restriction on the speed at which regions of spacetime may move relative to each other. So a small bubble of spacetime containing a spacecraft could travel faster than the speed of light, at least in principle. But one unanswered question was what happens to the bubble when quantum mechanics is taken into account. Now, a team of physicists have worked it out, and it's bad news: the bubble becomes unstable at superluminal speeds, making warp drives impossible (probably)."

The Wall Street Journal, quoting "people familiar with the matter," reported Wednesday that International Business Machines was in talks to buy the company for at least $6.5 billion in cash, a premium of more than 100 percent over the company's closing share price Tuesday. Officials of Sun and IBM could not immediately be reached for comment."

GameSetWatch has put up an article about the characteristics that give games in the survival-horror genre the ability to unnerve, startle, and scare players in ways that most games don't. The genre has seen a resurgence lately, with titles like Dead Space, F.E.A.R. 2, and Left 4 Dead posting strong sales numbers. What triggers your fight-or-flight impulses in games like these? From the article: "Being visual creatures, humans are most comforted by sight because of our ability to discern objects, action and consequences based on a picture. As a result, cutting visual stimuli and sticking purely to audio or speech is one of the best ways to keep a player on their toes. Even with weapons, it's very hard to find what you cannot see, and what you do not know. Even if visual stimuli is used, limiting or obfuscating the player's view can enhance the horror in a game, especially if the player sees it for an incredible short time. This can hint both at the difficulty of an upcoming encounter, or even allude to matters earlier in the narrative that the player will soon have to face."

Hugh Pickens writes "On the 200th anniversary of his birth, President Abraham Lincoln's popular image as a log-splitting bumpkin is being re-assessed as historians have discovered that Lincoln had an avid interest in cutting-edge technology and its applications. During the war, Lincoln haunted the telegraph office (which provided the instant-messaging of its day) for the latest news from the front; he encouraged weapons development and even tested some new rifles himself on the White House lawn; and he is the only US president to hold a patent (No. 6469, granted May 22, 1849). It was for a device to lift riverboats over shoals. 'He not only created his own invention but had ideas for other inventions, such as an agricultural steam plow and a naval steam ram, [and] was fascinated by patent cases as an attorney and also by new innovations during the Civil War,' says Jason Emerson, author of Lincoln the Inventor. But Lincoln's greatest contribution to the war effort was his use of the telegraph. When Lincoln took office the White House had no telegraph connection. Lincoln 'developed the modern electronic leadership model, says Tom Wheeler, author of Mr. Lincoln's T-Mails: The Untold Story of How Abraham Lincoln Used the Telegraph To Win the Civil War. At a time when electricity was a vague scientific concept and sending signals through wires was 'mind boggling,' Lincoln was fascinated by the telegraph and developed it into a political and military tool that allowed him to project himself to the front to monitor and track what was going on. 'If he were alive today, we'd call him an early adopter,' says Wheeler."

gclef writes "Buried deep in the details of the US stimulus package is an interesting provision that might go a long way toward helping Open Source software break into the medical area. It says that the Secretary of Health and Human Services should study the availability of open source health technology systems (PDF, page 488), compare their TCO against proprietary systems and report on what they find no later than Oct 1, 2010. Slashdotters may also be interested in the language that starts on page 553 of that PDF to see just what the final package says about broadband." The stimulus plan was approved by the Senate on Friday and is expected to be signed by President Obama by Monday.
