waderoush writes "Right now, content publishers who want to reach readers through dedicated mobile apps have to hire a separate engineering team to build each app — one for iOS (based on Objective-C), another for Android (Java), a third for Windows Phone (C#), etc. Yahoo's Platform Technology Group is working on an alternative: a set of JavaScript and HTML-based tools that would handle core UI and data-management tasks inside mobile apps for any operating system, moving developers closer to the nirvana of 'write once, run everywhere.' The tools are gradually being open-sourced — starting with Mojito, a framework for running hybrid server/browser module-widgets ('mojits') — and Yahoo is showing off what they can do in the form of Livestand, the news reader app it released for the iPad in November. In his first extensive public interview about Mojito and the larger 'Cocktails' project, Bruno Fernandez-Ruiz, chief architect at Yahoo's Platform Technology Group, explains how the tools work and why the company is sharing them."

AHuxley writes "Australia would like to follow the EU down the 'European Directive on Data Retention' path. Law enforcement agencies may have the option to request a log of all a users of interest telco usage without any review or time limits. From the article: 'The proposal — known popularly as ‘OzLog’ — first came to light in June 2010, when AGD confirmed it had been examining the European Directive on Data Retention (PDF) to consider whether it would be beneficial for Australia to adopt a similar regime. The directive requires telcos to record data such as the source, destination and timing of all emails and telephone calls – even including internet telephony.'"

An anonymous reader writes with news about work on Mozilla's Javascript engine. Quoting Mozilla engineer Luke Wagner's blog: "With web workers in separate runtimes, there were no significant multi-threaded runtime uses remaining. Furthermore, to achieve single-threaded compartments, the platform features that allowed JS to easily ship a closure off to another thread had been removed since closures fundamentally carry with them a reference to their original enclosing scope. Even non-Mozilla SpiderMonkey embeddings had reportedly experienced problems that pushed them toward a similar shared-nothing design. Thus, there was little reason to maintain the non-trivial complexity caused by multi-threading support. There are a lot of things that 'would be nice' but what pushed us over the edge is that a single-threaded runtime allows us to hoist a lot data currently stored per-compartment into the runtime. This provides immediate memory savings."

MrSeb writes "After more than five years in the pipeline, Mozilla Labs and the Rust community have released the first alpha of the Rust programming language compiler. The Rust language emphasizes concurrency and memory safety, and — if everything goes to plan — is ultimately being groomed to replace C++ as Mozilla's compiled language of choice, with Firefox (or parts of it) eventually being re-written in Rust."

An anonymous reader writes "An article by Andy Young in The Kernel makes the case that lessons in programming should be compulsory learning for modern school kids. He says, 'Computers help us automate and repeat the many complicated steps that make up the search for the answer to some of our hardest problems: whether that's a biologist attempting to model a genome or an office administrator tasked with searching an endless archive of data. The use of tools is a big part of what make us human, and the computer is humanity's most powerful tool. ... The computer makes us more efficient, and enables and empowers us to achieve far more than we ever could otherwise. Yet the majority of us are entirely dependent on a select few, to enable us to achieve what we want. Programming is the act of giving computers instructions to perform. This is true whether the output is your word processor, central heating or aircraft control system. If you can't code, you are forced to rely on those that can to ensure that you can benefit from the greatest tool at your disposal.'"

An anonymous reader points out the case of Saeed Malekpour, an Iranian-born permanent resident of Canada who worked as a web developer. In 2008, during a visit to Iran, Malekpour was arrested and detained by Iranian authorities on charges that he designed and moderated "adult content websites." In 2009, he was sentenced to death for "acting against the national security, insulting and desecrating the principles of Islam, and agitating the public mind." Malekpour wrote photo-uploading software, and in a letter he sent from prison, he said it was used by porn sites without his knowledge. This week an Iranian court reviewed the case and confirmed that the death sentence was an acceptable punishment. According to one Canadian publication, "Human rights monitors believe that Malekpour, one of a number of people held on Internet-related charges, is trapped by a convoluted justice system that is manipulated by rival factions in Iran."

oztiks writes "Lawyer Karen Sandler's heart condition means she needs a pacemaker to ward off sudden death. Instead of trusting that the vendor will create a flawless platform for the device to operate, Sandler has demanded to see the device's source code. Sandler's reasoning brings into question the device's reliably, stability, and oddly enough, security."

asgard4 writes "In recent years GPUs have become powerful computing devices whose power is not only used to generate pretty graphics on screen but also to perform heavy computation jobs that were exclusively reserved for high performance super computers in the past. Considering the vast diversity and rapid development cycle of GPUs from different vendors, it is not surprising that the ecosystem of programming environments has flourished fairly quickly as well, with multiple vendors, such as NVIDIA, AMD, and Microsoft, all coming up with their own solutions on how to program GPUs for more general purpose computing (also abbreviated GPGPU) applications. With OpenCL (short for Open Computing Language) the Khronos Group provides an industry standard for programming heavily parallel, heterogeneous systems with a language to write so-called kernels in a C-like language. The OpenCL Programming Guide gives you all the necessary knowledge to get started developing high-performing, parallel applications for such systems with OpenCL 1.1." Keep reading for the rest of asgard4's review.

First time accepted submitter CanEHdian writes "MIT news reports on research done resulting in a Faster-than-fast Fourier Transform algorithm. 'At the Association for Computing Machinery's Symposium on Discrete Algorithms (SODA) this week, a group of MIT researchers will present a new algorithm that, in a large range of practically important cases, improves on the fast Fourier transform. Under some circumstances, the improvement can be dramatic — a tenfold increase in speed. The new algorithm could be particularly useful for image compression, enabling, say, smartphones to wirelessly transmit large video files without draining their batteries or consuming their monthly bandwidth allotments.'"

snydeq writes "Increased emphasis on distinctive smartphone UIs means even more headaches for cross-platform mobile developers, writes Fatal Exception's Neil McAllister, especially as users continue to favor native over Web-based apps on mobile devices. 'Google and Microsoft are both placing renewed emphasis on their platforms' user experience. That means not just increased competition among smartphone and tablet platforms, but also new challenges for mobile application developers. ... The more the leading smartphone platform UIs differ from one another, the more effort is required to write apps that function comparably across all of them. Dialog boxes, screen transitions, and gestures that are appropriate for one platform might be all wrong for another. Coding the same app for three or four different sets of user interface guidelines adds yet another layer of cost and complexity to cross-platform app development."

wiredmikey writes "A Chinese computer programmer was arrested by U.S. authorities in New York on Wednesday, on charges that he stole proprietary source code while working on a project at the Federal Reserve Bank of New York. The man arrested, Bo Zhang of New York, worked as a contract employee developing a specific portion of the GWA's (Government-Wide Accounting and Reporting Program) source code at the Federal Reserve Bank of New York where the code is maintained. The complaint alleges that in the summer of 2011, Zhang stole the GWA code, something he admitted to in July 2011. Zhang said that he used the GWA Code in connection with a private business he ran training individuals in computer programming."

bonch writes "Microsoft has introduced a gamification plugin for Visual Studio that lets users win achievements and badges as they compete on leaderboards by writing code. The full list of achievements includes gems like 'Go To Hell' for using goto, and 'Potty Mouth' for using five different curses in one file. This is another example of Gamification, one of the latest trends to hit social media."

stephencrane writes "NYC is to open The Academy for Software Engineering, with a focus on software design and college preparation. It'll be a 'limited, unscreened' high school, which means admission won't be tied to grades or test scores; solely on interest (and presumably a lottery, once words gets out)." Would you want to go (or have gone) to such a school? Would you want your kids to attend?

GMGruman writes "A bug in Oracle Database that could take down large databases — or let a hacker do so — has been found, and Oracle promises a patch later today. When InfoWorld first heard of the bug two months ago, its investigation revealed how dangerous this bug could be, and after convincing Oracle to address the issue, InfoWorld held the news until a patch was available, so hackers could not exploit the bug in the meantime. Paul Venezia details just how this bug exposes companies to the possibility of databases going offline, and Eric Knorr asks Oracle users to help test the patch in their complex environments. (InfoWorld's tests in simpler environments show the patch works there.)"

An anonymous reader writes "I've been looking for an open source alternative to Dreamweaver, and haven't stumbled upon anything that works the way I need. Aptana and Bluefish are fantastic tools, but I cannot work exclusively with them, since Bluefish doesn't have that WYSIWYG functionality that is so important when you're also dealing with design, and Aptana doesn't have classic ASP support. I don't care much about the classic ASP support, but, even though I'm a PHP developer, I give support to classic ASP code on a daily basis. What open source tools are you guys working with out there? I'm really not looking for a Dreamweaver clone, just a tool that gets closer to cover my needs: WYSIWYG, PHP, HTML, CSS support, and less important, classic ASP support."

Skuto writes "At yesterdays linux.conf.au Browser miniconference in Ballarat, Australia, Mozilla engineer Nicholas Nethercote gave a detailed presentation about the history of Firefox's memory consumption. The 37 slides-with-notes explain in gritty detail what caused Firefox 4's memory usage to be higher than expected, how many leaks and accidental memory use bugs were tracked down with Valgrind plugins, as well as the pitfalls of common memory allocation strategies. Current work is now focused on reducing the memory usage of popular add-ons such as AdBlock, GreaseMonkey and Firebug. Required reading for people working on large software projects, or those who missed that Firefox is now one of the most memory-efficient browsers in heavy usage."

mikejuk writes with an excerpt from an article at i-programmer about a neat graphics demo written in Dart: "One of the difficulties in getting a new computer language accepted by a wider audience is that there is doubt that it is real. Is it a toy language that just proves a concept or can it do real work? In the case of Dart, which is Google's replacement for JavaScript, the development is speeding ahead at a rate that is impressive but worrying. To prove that Dart is already a language that can be used, we now have a port of the well known 2D physics engine Box2D, the one Angry Birds uses, to Dart." Box2D has previously been ported to Javascript. Source is available at Google Code (under the Apache license). Note that you'll need Chromium to run the demos.

New submitter rnmartinez writes "As the Project Manager for a non-profit looking to implement a tech project, I am running into a few dilemmas, and as a casual Slashdotter I could really use some help. I'll start with a brief explanation of the project. We research issues in Canadian Immigrants, and found that there was a lack of recent, unaggregated information. As we dug further, we found that some data was available, but there was no central repository. Therefore, we are building a web based service to collect this data, with the intent of having it display in Google Maps and then be downloadable as a CSV file that is readable in GIS software such as ESRI Arcsoft, so that data may be visualized." The dilemma: "...It seems that MS SQL offers more functions with regards to geometry built in then MySQL, and my developers (good guys, but MS guys at heart) want me to switch to .net NUKE/MSSQL and ditch the open source stuff." Read on for further details.

The company is working hard to engage with the Java User Group leaders and Java Champions, membership of the OpenJDK project is growing, and the company is making efforts to reform the Java Community Process to improve transparency. The firm has also published a clear, well-defined Java roadmap toward Java 8 and Java 9."
