postfail writes 'lwn.net coverage of the 2009 Linux Kernel Summit includes a recap of a presentation by Google engineers on how they use Linux. According to the article, a team of 30 Google engineers is rebasing to the mainline kernel every 17 months, presently carrying 1208 patches to 2.6.26 and inserting almost 300,000 lines of code; roughly 25% of those patches are backports of newer features.'

Riskable writes "Remember that $200,000 Contest For a Better Open-WRT Wireless Router GUI? Today Ubiquiti posted the winning entries to their support wiki. The grand prize was a tie between PyCI (written by yours truly) and NETSHe with OpenNET as the runner up. Source code and firmware images for each entry are available for download on their respective wiki pages. I'll be setting up a project page for PyCI (and l2sh) soon to make it a participatory open source product. Even if you don't have a RouterStation, or don't care about OpenWRT, there are numerous Python modules and tools inside of PyCI that could prove useful to other open source projects (e.g. iptables.py can read/interpret over 400 permutations of the iptables command). I'll also be checking the comments if anyone has any questions for me about PyCI or the contest in general. BTW: I'd like to thank all the commenters in the original article that insinuated that the technical requirements were impossible and/or that making a GUI to configure such complex things is a waste of time. I read every one and I wouldn't have made it such an obsession otherwise!"

Dan Jones writes "Google has open sourced several of its key JavaScript application development tools, hoping that they will prove useful for external programmers to build faster Web applications. According to Google, by enabling and allowing developers to use the same tools that Google uses, they can not only build rich applications but also make the Web really fast. The Closure JavaScript compiler and library are used as the standard Javascript library for pretty much any large, public Web application that Google is serving today, including some of its most popular Web applications, including Gmail, Google Docs and Google Maps. Google has also released Closure Templates which are designed to automate the dynamic creation of HTML. The announcement comes a few months after Google released and open sourced the NX server."

anomnomnomymous writes "Just a week after Unity announced its engine is now available for free to indie users, Epic Games has revealed a free version of its popular Unreal Engine technology. Called the Unreal Development Kit (UDK), it is a free edition of UE3 that allows community, modder and indie users more access to the engine's features and is available for all. Epic said game developers, students, hobbyists, researchers, creators of 3D visualizations and simulations plus digital filmmakers can all take advantage of the UDK for non-commercial use. The UDK site also offers detailed product features, technical documentation, commercial licensing terms and support resources."

An anonymous reader writes "In a curious contrast to conventional wisdom, there are reports of X11 Chromium being faster than Windows or Mac versions. In the thread titled 'Why is Linux Chrome so fast?,' a developer speculates that it is due to the use of X11 capabilities: 'On X-windows [sic], the renderer backingstores are managed by the X server, and the transport DIBs are also managed by the X server. So, we avoid a lot of memcpy costs incurred on Windows due to keeping the backingstores in main memory there.' Has the design of X11 withstood the test of time better than people tend to give it credit for?"

shreshtha contributes this snippet from MIT's Technology Review: "Martin Rinard, a professor of computer science at MIT, is unabashed about the ultimate goal of his group's research: 'delivering an immortal, invulnerable program.' In work presented this month at the ACM Symposium on Operating Systems Principles in Big Sky, MT, his group has developed software that can find and fix certain types of software bugs within a matter of minutes." Interestingly, this software doesn't need access to the source code of the target program.

Ponca City, We love you writes "Dr. Dobbs reports that Alex Waibel, professor of computer science and language technologies at Carnegie Mellon University, has developed an iPhone application that turns the iPhone into a translator that converts English speech into Spanish, or vice versa. Users simply speak a sentence or two at a time into the iPhone and the iPhone will respond with an audible translation. 'Jibbigo's software runs on the iPhone itself, so it doesn't need to be connected to the Web to access a distant server,' says Waibel. Waibel is a leader in speech-to-speech translation and multimodal speech interfaces, creating the first real-time, speech-to-speech translator for English, German and Japanese. 'Automated speech translation is an expensive proposition that has been supported primarily by large government grants,' says Waibel. 'But our sponsors are impatient to see this technology become more widely available and we, as researchers, are eager to find new revenues that will help us extend this technology to more of the 6,000 languages now spoken worldwide.'"

stoolpigeon writes "The Android 2.0 SDK is now available from Google. This puts to bed concerns about Google not releasing the SDK or perhaps being in some kind of exclusivity deal with Verizon around 2.0. The release notes give a nice overview of what is there. Those who already have the SDK can grab the updated tools as SDK components; everyone else will pick up everything when downloading the new SDK." Relatedly, reader riffzifnab reports that Google has also announced Google Maps Navigation, a GPS application for Android 2.0 that takes voice input and integrates with internet searches and Street View.

An anonymous reader writes "Maemo 5 and Android have received a lot of publicity lately, despite the former not even shipping yet. Both have become famous partly for using the Linux kernel, but now that we have a choice, how do we pick one? Is the issue as mundane as choosing your favorite desktop distribution, or is there a more significant difference? This article compares the two from an end user and developer perspective, emphasizing root access and ease of sharing code."

1sockchuck writes "Amazon Web Services has added a relational database service to host MySQL databases in the cloud, and is also dropping prices on its Amazon EC2 compute service by as much as 15 percent. Amazon says the new service lets users focus on development rather than maintenance, but it will probably be bad news for startups offering database services built atop Amazon's cloud. Cloud Avenue warns that Amazon RDS should serve as 'a warning bell for the companies that build their entire business on Amazon ecosystem. ... They are just one announcement away from complete destruction.' Data Center Knowledge has a roundup of analysis and commentary on Amazon RDS and its impact on the cloud ecosystem."
