When Rewriting an App Actually Makes Sense 289

Posted by timothy from the old-app-was-starting-to-fester dept.
vlangber writes "Joel Spolsky wrote a famous blog post back in 2000 called 'Things You Should Never Do, Part I,' where he wrote the following: '[T]he single worst strategic mistake that any software company can make: They decided to rewrite the code from scratch.' Here is a story about a software company that decided to rewrite their application from scratch, and their experiences from that process."

Ubuntu's "Lucid Lynx" Enters Beta 366

Posted by timothy from the but-that-danged-button-arrangement-sucks dept.
ActionDesignStudios writes "The upcoming release of Ubuntu, titled 'Lucid Lynx,' has just entered the beta cycle. Alongside the usual desktop and server versions, a special version has been released that is designed to run on Amazon's EC2 cloud service. This release of Ubuntu does away with the brown 'Human' Gnome theme we've all become accustomed to, replaced by a new version Canonical says is inspired by light. The new release also includes much better integration with social networking services such as Twitter, identi.ca and Facebook, among others."

Sony Develops a Universal Game Console Controller 62

Posted by Soulskill from the floats-like-a-dreamcast-stings-like-a-wii dept.
Go Rumors has discovered that Sony recently applied for a patent on a "universal game console controller." According to the patent filing, the controller "includes a hand-holdable housing and a touch sensitive liquid crystal display (LCD) on the housing. The LCD is caused to present, depending on what type of game console a user has selected, a controller key layout for a first type of game console or a controller key layout for a second type of game console. A key layout includes plural keys selectable by a user to input commands to a game console."

Colliding Particles Can Make Black Holes After All 269

Posted by Soulskill from the act-now-while-supplies-last dept.
cremeglace writes with this excerpt from ScienceNOW: "You've heard the controversy. Particle physicists predict the world's new highest-energy atom smasher, the Large Hadron Collider (LHC) near Geneva, Switzerland, might create tiny black holes, which they say would be a fantastic discovery. Some doomsayers fear those black holes might gobble up the Earth — physicists say that's impossible — and have petitioned the United Nations to stop the $5.5 billion LHC. Curiously, though, nobody had ever shown that the prevailing theory of gravity, Einstein's theory of general relativity, actually predicts that a black hole can be made this way. Now a computer model shows conclusively for the first time that a particle collision really can make a black hole." That said, they estimate the required energy for creating a black hole this way to be roughly "a quintillion times higher than the LHC's maximum"; though if one of the theories requiring compact extra dimensions is true, the energy could be lower.

All the formulation for the prediction of water properties are published by International Association for the Properties of Water and Steam (IAPWS) so that they can be used. It is often important to use exactly the same correlations so that that all the thermodynamic data are self-consistent. Therefore the formulations are standardized by an international body. I do not think that the use of this formulae is in any way restricted because such restriction would defeat the very purpose - standarization. See http://www.iapws.org/ for the collection of the current formulations. There may be a restriction for a particular implementation (computer program) or sets of tables ( "lookup tables" and interpolation are often used for performance). Not sure. Hope someone starts an extension to implement these kind of things in Gnumeric. Cheers. Ephraim the horse.
