An anonymous reader writes "With its new Caffeine search indexing system, Google has moved away from its MapReduce distributed number crunching platform in favor of a setup that mirrors database programming. The index is stored in Google's BigTable distributed database, and Caffeine allows for incremental changes to the database itself. The system also uses an update to the Google File System codenamed 'Colossus.'"

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."

ByronScott writes "In today's 'gross news' category, some female insects just might be getting lucky. As an alternative to toxic pesticides, scientists at the Hebrew University of Jerusalem have created 'super-sexed' sterilized male leafhoppers to knock bug boots with females in the wild, resulting in decreased populations. Yes, that means that the female bugs will miss out on the joys of motherhood, but the idea that the insects will be having some fun instead of being gassed to death by poisons is pretty cool."

An anonymous reader writes "Wondering where all that bloat comes from, causing even the classic 'Hello world' to weigh in at 11 KB? An MIT programmer decided to make a Linux C program so simple, she could explain every byte of the assembly. She found that gcc was including libc even when you don't ask for it. The blog shows how to compile a much simpler 'Hello world,' using no libraries at all. This takes me back to the days of programming bare-metal on DOS!"

An anonymous reader writes "The Australian Informatics Olympiad programming test is being run in a couple of months. I'm an experienced programmer and I'm thinking of volunteering to tutor interested kids at my children's school to get them ready. There will be children of all levels in the group, from those that can't write 'hello world' in any language, to somewhat experienced programmers. For those starting from scratch, I'm wondering what language to teach them to code in. Accepted languages are C, C++, Pascal, Java, PHP, Python and Visual Basic. I'm leaning towards Python, because it is a powerful language with a simple syntax. However, the test has a run-time CPU seconds limit, so using an interpreted language like Python could put the students at a disadvantage compared to using C. Is it better to teach them something in 2 months that they're likely to be able to code in but possibly run foul of the CPU time limit, or struggle to teach them to code in a more complicated syntax like C/C++ which would however give them the best chance of having a fast solution?"

An anonymous reader writes "Over the last two months I ported Quake 3 to Android as a hobby project. It only took a few days to get the game working. More time was spent on tweaking the game experience. Right now the game runs at 25fps on a Motorola Milestone/Droid. 'Normally when you compile C/C++ code using the Android NDK, the compiler targets a generic ARMv5 CPU which uses software floating-point. Without any optimizations and audio Quake 3 runs at 22fps. Since Quake 3 uses a lot of floating-point calculations, I tried a better C-compiler (GCC 4.4.0 from Android GIT) which supports modern CPUs and Neon SIMD instructions. Quake 3 optimized for Cortex-A8 with Neon is about 15% faster without audio and 35% with audio compared to the generic ARMv5 build. Most likely the performance improvement compared to the ARMv5 build is not that big because the system libraries of the Milestone have been compiled with FPU support, so sin/cos/log/.. take advantage of the FPU.''

BJ writes "The Linux Action Show, the Linux-podcast to end all Linux-podcasts, is returning with their 11th season after over 7 months off the air. Kicking it all off with a live streaming event this Saturday at 5pm. Topics are set to include: Maemo/Moblin merging into Meego, Open Source Nividia drivers with 3D, KDE 4.4 and much, much more."

The Wii and various mobile gaming platforms have done wonders for the trend toward casual or "easy" games. But the success of a few recent titles, despite their difficulty, has caused some to wonder whether the pendulum has swung too far; whether a little frustration can be seen as a good thing. Quoting: "The evidence is subtle but compelling. For one example, look to major consumer website GameSpot's Game of the Year for 2009: Atlus' PS3 RPG Demon's Souls, which received widespread critical acclaim – none of which failed to include a mention of the game's steep challenge. GameSpot called it 'ruthlessly, unforgivingly difficult.' Demon's Souls was a sleeper hit, an anomaly in the era of accessibility. One would think the deck was stacked against a game that demanded such vicious persistence, such precise attention – and yet a surge of praise from critics and developers alike praised the game for reintroducing the experience of meaningful challenge, of a game that demanded something from its players rather than looked for ways to hand them things. It wasn't just Demon's Souls that recently flipped the proverbial bird to the 'gaming for everyone' trend. In many ways, the independent development scene can be viewed on the macro level as a harbinger of trends to come, and over the past year and into 2010, many indies have decided to be brutal to their players."

An anonymous reader writes "One of the basic utilities supplied with any operating system is a desktop calculator. These are often simple utilities that are perfectly adequate for basic use. They typically include trigonometric functions, logarithms, factorials, parentheses and a memory function. However, the calculators featured in this article are significantly more sophisticated with the ability to process difficult mathematical functions, to plot graphs in 2D and 3D, and much more. Occasionally, the calculator tool provided with an operating system did not engender any confidence. The classic example being the calculator shipped with Windows 3.1 which could not even reliably subtract two numbers. Rest assured, the calculators listed below are of precision quality."

Michael_Curator writes "It's no secret that commercial airplanes are heavily computerized, but as the mystery of Air France Flight 447 unfolds, we need to come to grips with the fact that in many cases, airline pilots' hands are tied when it comes to responding effectively to an emergency situation. Boeing planes allow pilots to take over from computers during emergency situations, Airbus planes do not. It's not a design flaw — it's a philosophical divide. It's essentially a question of what do you trust most: a human being's ingenuity or a computer's infinitely faster access and reaction to information. It's not surprising that an American company errs on the side of individual freedom while a European company is more inclined to favor an approach that relies on systems. As passengers, we should have the right to ask whether we're putting our lives in the hands of a computer rather than the battle-tested pilot sitting up front, and we should have right to deplane if we don't like the answer."

All is not sweetness and light in the wake of the Apple WWDC kickoff announcements, especially concerning the evolution of the iPhone. Reader Hugh Pickens writes: "AT&T will offer the new iPhone 3G S when it debuts later this month at a cost of $199 and $299 for the 16GB and 32GB models, but only to new customers and those who qualify for the discounted price. AT&T subscribers with an iPhone 3G who are not eligible for an upgrade — those not near the end of their two-year contracts — will have to pay $200 more — $399 for the 16GB model and $499 for the 32GB model. 'This is ridiculous and slap in the face to long-time loyal iPhone customers like me who switched from T-Mobile and the only reason was the iPhone,' writes one unhappy iPhone customer. 'We have to mount a vigorous campaign to change this policy. Call your local AT&T and ask for the manager and complain. Send e-mails and post in forums everywhere.' The issue is spurring heavy debate on support discussion forums, with some customers supporting AT&T. 'The option you have is to honor the contract you freely committed yourself to,' says one forum member. 'If you want to upgrade early then you will have to pay full price with no subsidy discount. You can't blame anyone but yourself for your predicament.'"
