While Mindbridge didn't start out as an open source company, it has since managed to save what they can only describe as "bunches of money" by switching to Linux. "Today, Mindbridge has repurposed itself as an open-source-friendly company, and revamped its infrastructure to run completely on Linux and other open source software. 'Having deployed [Linux servers] to our customers, we turned around and said, we can do the same thing internally and save bunches of money. We began a systematic but slow flipping of servers from the Microsoft world over to predominantly Linux — although there are a few BSD boxes around as well,' Christian says. 'It's to the point that today I only have two production Windows servers left, out of 15 or so.'"

An anonymous reader writes "I prefer software that takes as little hard drive space and RAM as possible. I can't stand bloated software like iTunes, as compared to Foobar or classic Winamp; or Windows Media Player, as compared to VLC or Media Player Classic. What are some of your favorite applications which are a little less bloated?"

Abhinav Peddada writes "Ars Technica takes Opera 9.5, the latest from Opera's stable, for a test run and finds some interesting results, including it being a 'solid improvement to an already very strong browser.' On the performance front, Ars Technica reports 'Opera 9.5 scored slightly higher (281ms) than the previous released version, 9.23 (546ms). And Opera 9.x, let it be known, smacks silly the likes of Firefox and Internet Explorer, which tend to have results in the 900-1500ms range on this test machine (a 1.8 GHz Core 2 Duo with 2GB RAM). Opera was 50 percent faster on average than Firefox, and 100 percent faster than IE7 on Windows Vista, for instance.'"

jpkunst sends us to Computerworld for a look at Michael Stonebraker's opinion that RDBMSs "should be considered legacy technology." Computerworld adds some background and analysis to Stonebraker's comments, which appear in a new blog, The Database Column. Stonebraker co-created the Ingres and Postgres technology while a researcher at UC Berkeley in the early 1970s. He predicts that "column stores will take over the [data] warehouse market over time, completely displacing row stores."

inkslinger77 writes "The two Mars rovers that have been carefully conserving critical power supplies since June, when the summer dust-storm season began on the red planet, are now springing back to work as the storms subside. Typically, the solar panels on each rover produce about 700 watt-hours of electricity per day — enough to light a 100-watt bulb for seven hours, according to NASA. But this year's dust storms reduced that to as little as 128 watt hours per day. When daily power generation is down to less than 400 watt-hours, the rovers suspend their driving on the planet and stop using their robotic arms, cameras and other instruments. But they are back in action now!"

JSM writes to tell us that Apple released a new version of their popular iPod music player today that boasts, among other things, an iPhone-like touch screen and Wi-Fi capabilities. "The iPod Touch will feature the Safari Internet browser and, like the iPhone, play YouTube videos. Apple also announced a new version of its iTunes music store that will allow users to buy songs wirelessly. iTunes will also sell customizable 99-cent ringtones for the iPhone."

Evan Skolnick has been writing for comic books and games for a good, long while now. He thinks that the most important elements to good games writing can be found in one of the touchstones of nerd culture: Star Trek. In an hour-long presentation at GDC Austin today, he discussed some of the most important lessons that can be derived from the Star Trek franchise as regards storytelling, character development, and the importance of not starting a story with "all we have to do now is wait." Read on for notes from his equally informative and humorous look at crafting a great tale.

Mark Goldberg writes "UN Dispatch, the United Nations affairs blog I write, just posted an item that may interest this community. Joel Selanikio, a medical doctor and technologist, writes to us from Zambia to relay how PDA devices are quietly revolutionizing public health services in sub-Saharan Africa. Selanikio runs a non-profit called DataDyne.org that trains local health officials to use PDAs equipped with an open source software tool to track outbreaks, coordinate vaccination efforts, and perform other vital public health tasks. So far, says Selanikio, the pilot program in Zambia has been a resounding success.

Today Microsoft announced the release of Silverlight 1.0 for Windows and Mac OS X. This cross-browser, cross-platform browser plug-in is fully supported and competes directly with Adobe Flash. Included in this release was the promise from Microsoft to support the 100% compatible Linux version, called Moonlight.

ObsessiveMathsFreak writes "I'm an applied mathematician who has recently needed to obtain good numerical approximations to the classic second-order wave equation, preferably in three space dimensions. A lot of googling has not revealed much on what I had assumed would be a well-studied problem. Most of the standard numerical methods, finite difference/finite element methods, don't seem to work very well in the case of variable wave speed at different points in the domain, which is exactly the case that I need. Are any in this community working on numerically solving wave equation problems? What numerical methods do you use, and which programs do you find best suited to the task? How do you deal with stability issues, boundary/initial values, and other pitfalls? Are there different methods for electromagnetic wave problems? Finally, when the numbers have all been crunched, how do you visualize your hard-earned data?"

shafty023 writes "The Xbox Live online service disallows screen names like LINUXRULES, L I N U X, and other variations of these kinds. Other bloggers are reporting that variants of 'Unix' also result in the message: 'Your motto contains inappropriate language. Please try again.'" If this is an extension of Microsoft's anti-Linux campaign, perhaps it's time they gave it up.

theodp writes "Last week, the USPTO published a rather odd Microsoft patent application for Content Ratings and Recommendations, which describes how religious-based communities and other 'subcultures' can use the patent-pending process to prevent their members from viewing undesirable television programs and movies."

A user writes "Medical researchers in Britain have succeeded in growing a heart valve from adult stem cells taken from bone marrow. The research is being reported in the journal of the Royal Society today. Growing a heart value from your own cells means that tissue rejection isn't an issue."

MarkWhittington writes "2007 marks the fiftieth anniversary of the Space Age, agreed by most to have begun with the launch of the first artificial Earth satellite, Sputnik, on October 4th, 1957. While some are taking stock of the last fifty years of space exploration, noting what has been accomplished and, more importantly, what has not been accomplished, others are wondering what the next fifty years might bring."

Jerry Asher writes "Not all of my coworkers are careful about spelling errors. Sometimes this causes real embarrassment as spelling errors creep into software interfaces. Does anyone know of spell checkers for programming languages? I don't want a text spell checker, I want a programming-language-aware spell checker. A spell checker that I can pass all of my code through and will flag spelling errors in function names, variable names, and comments, but will ignore language keywords, language constructs and expressions, and various programming styles (camel code, or underscores, or...). I want a spell checker that knows that void *functionSigniture(char *myRoutine) contains one spelling error. Does anyone have such a thing for Java or C++? Are there any Eclipse plugins that do this?"
