But a recent 28 page paper in The Montana Mathematics Enthusiast (PDF) spends a great deal of time fielding questions by researchers who have explored this in depth and this seemingly impossibility is further explored in a brief history by Dev Gualtieri who presents the digit manipulation proof: Let a = 0.999... then we can multiply both sides by ten yielding 10a = 9.999... then subtracting a (which is 0.999...) from both sides we get 10a — a = 9.999... — 0.999... which reduces to 9a = 9 and thus a = 1. Mathematicians as far back as Euler have used various means to prove 0.999... = 1."

If you head on over to the erkie GitHub page there's a JavaScript bookmarklet you can drag and add to your bookmarks toolbar. Then just visit any website and click the bookmarklet. An Asteroids-style ship should appear that you can move around with the arrow keys. Press space and it will start firing bullets which destroy page content."

eldavojohn writes "The AFP brings a story of a growing concern that children in China and Japan suffer from 'character amnesia' when asked to write the complex characters they are so used to inputting via alphabet-based systems. The article claims this is a growing problem. In China, they have a word for it: 'tibiwangzi,' which means 'take pen, forget paper.' China Youth Daily polled 2,072 people and found that 83% have problems writing characters (although there's no indication if that was an online poll or not). A young woman who was interviewed explained her workaround: 'When I can't remember, I will take out my cellphone and find it (the character) and then copy it down.'"

Hugh Pickens writes "In hospitals around the country, nurses connect and disconnect interchangeable clear plastic tubing sticking out of patients' bodies to deliver or extract medicine, nutrition, fluids, gases or blood — sometimes with deadly consequences. Tubes intended to inflate blood-pressure cuffs have been connected to intravenous lines leading to deadly air embolisms, intravenous fluids have been connected to tubes intended to deliver oxygen, leading to suffocation, and in 2006 a nurse at in Wisconsin mistakenly put a spinal anesthetic into a vein, killing 16-year-old who was giving birth. 'Nurses should not have to work in an environment where it is even possible to make that kind of mistake,' says Nancy Pratt, a vocal advocate for changing the system. Critics say the tubing problem, which has gone on for decades, is an example of how the FDA fails to protect the public. 'FDA could fix this tubing problem tomorrow, but because the agency is so worried about making industry happy, people continue to die,' says Dr. Robert Smith." This reminds me of the sort of problem that Michael Cohen addressed in a slightly different medical context (winning a MacArthur Foundation grant) a few years ago.

An anonymous reader writes "Apparently the force is strong with LucasFilm's legal department, as they've sued the company Jedi Mind for trademark infringement and breach of contract, among other things. While LucasFilm doesn't actually own a trademark on 'Jedi,' it claims that its related marks are close enough, and that Jedi Mind had agreed last year to phase out the use of 'Jedi' in its name and product names."

j0ris writes "The Klingon are passionate opera-lovers, but little is known about their highly evolved form of musical expression. Floris Schonfeld is the initiator and director of 'u', the first authentic Klingon opera on earth. He studied Klingon music theory for over a year, and together with several experts developed various indigenous Klingon instruments. The Terran Klingon Research Ensemble has been set up to further develop a coherent Klingon musical practice amongst human musicians. 'u' premieres on September 9 in The Hague, Netherlands. An invitation by Klingon language expert Marc Okrand has been sent to Kronos, home planet of the Klingons, via radio telescope."

An anonymous reader sends news that the beta tag has come off of id's Quake Live, and they've added two subscription plans to monetize the game. The announcement asserts early and often that the game's current "Standard" play options will remain free-to-play. The lower subscription tier gets extra maps, a new Freeze Tag game mode, and clan creation abilities, among other things, for $2 per month. The higher plan, which is twice as expensive, grants players those benefits plus the capability to create their own private servers.

An anonymous reader writes "Last year, I got the opportunity to port Remedy Entertainment's Death Rally to modern platforms off its original MS-DOS sources. I wrote an article about the porting process for Game Developer magazine, and now I've posted the text of the article for general consumption. 'The source software platform was DOS, Watcom C, and some Dos4GW-style DOS extender. The extender basically meant you could use more than 640k of memory, and would not need any weird code for data larger than 64k. The game displayed in VESA 640x480 and MCGA 320x200 graphics modes, all with 8-bit palettes; there was no true color anywhere. There were also some per-frame palette change tricks that emulators have trouble with. The source code was mostly pure C with a couple dozen inline assembly functions. There were a few missing subsystems, specifically audio and networking, which would have to be replaced completely anyway, as well as one file for which the source code was lost and only a compiled object was available.'"
