Project To Mainline Android Kernel Changes Formed 73

Posted by Unknown Lamer from the keep-on-merging dept.
ghostoftiber writes "From the article: 'Tim Bird, a Sony engineering veteran and the chair of the Architecture Group of the Linux Foundation's CE Workgroup, has announced a new concerted effort to get Android's changes to the Linux kernel back into the mainline Linux kernel tree.' Android has been using Linux 2.6.x for its devices since its release, with patches from Google. To date they haven't been merged back into the kernel mainline but existed on kernel.org. Some of the features such as wakelocks would help with Linux tablet projects, but other features aren't fully realized and support remains spotty. The radio interface layer ... still exists as an ATI/Nvidia-esque shim loader scheme with modem 'drivers' being nothing more than ihex files loaded by open code."

October, November the Worst Months For Writing Buggy Code 136

Posted by Soulskill from the blame-the-halloween-candy-coma dept.
chicksdaddy writes "Data from application testing firm Veracode suggests that the quality of application code submitted for auditing is pretty much constant throughout the year — except for the months of October and November, when the average density of vulnerabilities in the code jumps considerably. But why? Is it the pressure of deadlines? The stress of developers' lives (kids back to school, etc.)?"

Firefox 9 Released, JavaScript Performance Greatly Improved 330

Posted by Unknown Lamer from the and-they-say-functional-programming-is-useless dept.
MrSeb writes "Firefox 9 is now available — but unlike its previous rapid release forebears where not a lot changed, a huge feature has landed with the new version: the JavaScript engine now has type inference enabled. This simple switch has resulted in a 20-30% JS execution speed increase (PDF), putting JaegerMonkey back in line with Chrome's V8 engine, and even pulling ahead in some cases. If you switched away from Firefox to IE or Chrome for improved JS performance, now is probably the time to give Firefox another shot."

MIT Software Allows Queries On Encrypted Databases 68

Posted by Soulskill from the cutting-out-the-middleman dept.
Sparrowvsrevolution writes "CryptDB, a piece of database software that MIT researchers presented at the Symposium on Operating System Principles in October, allows users to send queries to an encrypted SQL database and get results without decrypting the stored information. CryptDB works by nesting data in several layers of cryptography (PDF), each of which has a different key and allows a different kind of simple operation on encrypted data. It doesn't work with every kind of calculation, and it's not the first system to offer this sort of computation on encrypted data. But it may be the only practical one. A previous crypto scheme that allowed operations on encrypted data multiplied computing time by a factor of a trillion. This one adds only 15-26%."

Ask Slashdot: Entry-Level Robotics Kits For Young Teenagers? 153

Posted by timothy from the old-teenagers-much-grumpier dept.
An anonymous reader writes "So, it's that wonderful time of year again. Instead of buying the latest, greatest whiz-bang, overpriced fad toy of the year, I thought I might try my hand at corrupting my nieces (ages 12 and 14) in a nerdier direction with some sort of introductory robotics kit. They have no programming experience, and part of my idea is that it would be encouraging for them to see interactions of their code that they write with the real-world by being able to control some actuators and read sensors. The first thing that comes to mind is Lego Mindstorms, but I find them a bit on the pricey side of things. My budget falls between $40 and $100, and the ideal kit would focus more on the software side than on soldering together circuits. I'd be looking for a kit that provides an easy to learn API and development tools that will work with a standard Windows PC. I don't mind spending a few afternoons helping them out with the basics, but I'd like for them to be able to be able to explore on their own after grasping the initial concepts. Has anybody gotten their younger relations into programming through robotics, and what kits might you recommend?"

GPL, Copyleft Use Declining Fast 808

Posted by timothy from the taking-great-liberties dept.
itwbennett writes "Use of the GPL, LGPL, and AGPL set of licenses is declining at an accelerating rate, according to new analysis by the 451 Group's Matthew Aslett. In fact, the 451 Group projects that GPL usage will hit 50% by September 2012. Instead, developers are licensing projects under permissive licenses such as the MIT, Apache (ASL), BSD, and Ms-PL. The shift started in 2007 and has been gathering momentum ever since. Blogger Brian Proffitt posits that 'the creation of the GPLv3 and the sometimes contentious discussion that led up to it' may be partly responsible for the move away from the GPL."

Why Developers Still Prefer iOS To Android 614

Posted by timothy from the addictive-chemicals-are-my-theory dept.
An anonymous reader writes "Google Chariman Eric Schmidt recently addressed an Android user lamenting the fact that that mobile apps are often released on Apple's iOS platform well before they finally reach Android. Schmidt cooly and curiously explained that this dynamic will change in just 6 months. Here's why he's wrong. Though Google brags about the total number of Android users, developers care about certain kinds of users (those that pay for apps). A similar dynamic can be found in television advertising, where advertisers will more money for ad spots on less popular shows in order to reach desirable demographics, even though other programs may have many millions of more viewers."

Qt 4.8.0 Released 90

Posted by timothy from the how-qt-it-looks dept.
jrepin duly notes the release of Qt 4.8.0, and extracts from the announcement some of the key changes for developers: "Qt Platform Abstraction (QPA) restructures the GUI stack to enable easier porting of Qt to different windowing systems and devices. Threaded OpenGL enables us to render OpenGL from more than one thread concurrently. HTTP requests are now handled in a separate thread by default. The file system stack received some heavy lifting under the hood. The result is better I/O performance."

Oracle Sued For 'Extortion, Lies' By Montclair State University 359

Posted by timothy from the their-reputation-precedes-them dept.
angry tapir writes "Montclair State University is suing Oracle in connection with a troubled ERP (enterprise resource planning) project. Montclair's complaint, filed Tuesday in U.S. District Court for the District of New Jersey, states that Oracle made an array of 'intentionally false statements' regarding the functionality of its base ERP system, the amount of customization that would be required, and the amount of 'time, resources, and personnel that the University would have to devote.' 'Ultimately, after missing a critical go-live deadline for the University's finance system, Oracle sought to extort millions of dollars from the University by advising the University that it would not complete the implementation of the ... project unless the University agreed to pay millions of dollars more than the fixed fee the University and Oracle had previously agreed to,' it adds."

Firefox Too Big To Link On 32-bit Windows 753

Posted by Unknown Lamer from the ate-too-many-pizzas dept.
An anonymous reader writes "Firefox has gotten so large that it cannot be compiled with PGO on a 32-bit linker anymore, due to the virtual memory limitation of 3 GB. This problem had happened last year with 2 GB, which was worked around by adding a/3GB switch to the Windows build servers. Now the problem is back, and things aren't quite that simple anymore." This only affects the inbound branch, but from the looks of it new code is no longer being accepted until they can trim things from the build to make it work again. The long term solution is to build the 32-bit binaries on a 64-bit system.

NVIDIA Releases Source To CUDA Compiler 89

Posted by Unknown Lamer from the not-quite-there-yet dept.
An anonymous reader writes "NVIDIA has announced they have 'open-sourced' their new CUDA compiler so that their GPGPU platform can be brought to new architectures. NVIDIA's CUDA compiler is based upon LLVM. At the moment though they seem to be restricting the source code's access to 'qualified' individuals.' The official press release implies wider access to the source will happen later. It so happens that a few days ago AMD opened their OpenCL backend and added initial support to the Free Software r600 driver.

Ask Slashdot: How To Get Non-Developers To Send Meaningful Bug Reports? 360

Posted by Soulskill from the it's-broken-just-fix-it dept.
DemonGenius writes "I'm in the midst of a major rollout of one of our primary internal applications at work and we have a beta version available for all the staff to use. The problem here is most of the staff don't know how to send reports meaningful enough to get us devs started on solving their problems without constant back and forth correspondence that wastes both developer time and theirs. Some common examples are: screenshots of the YSOD that don't include the page URL, scaled screenshots that are unreadable, the complaint that wants to be a bug report but is still just a complaint, etc. From the user's perspective, they just send an email, but that email registers in our tracking system. Any thoughts on how to get the non-devs sending us descriptive and/or meaningful reports? Does anyone here have an efficient and user-friendly bug tracking system/policy/standard at their workplace? How does it work?"

Facebook Releases JIT PHP Compiler 244

Posted by Unknown Lamer from the history-repeats-itself dept.
angry tapir writes, quoting a Techworld article: "In its continuing endeavor to serve its 800 million users as quickly as possible, Facebook is once again revamping the way it handles its PHP-based Web pages. Facebook has posted ... its HipHop Virtual Machine (HHVM), which the company's engineers call a just-in-time PHP compiler. According to Facebook, this PHP execution engine is 60 percent faster than its current PHP interpreter and uses 90 percent less memory." Facebook has a weblog post with a more technical description.
