Rootbeer GPU Compiler Lets Almost Any Java Code Run On the GPU 304

An anonymous reader writes "Today the source code to the Rootbeer GPU Compiler was released as open source on github. This work allows for a developer to use almost any Java code on the GPU. It is free, open source and highly tested. Rootbeer is the most full featured translator to convert Java Bytecode to CUDA. It allows arbitrary graphs of objects to be serialized to the GPU and the GPU kernel to be written in Java." Rootbeer is the work of Syracuse University instructor Phil Pratt-Szeliga.

Will Online Learning Disrupt Programming Language Adoption? 193

theodp writes "Back in the day, getting traction for a new programming language was next to impossible. First, one needed a textbook publishing deal. Then, one needed a critical mass of CS profs across the country to convince their departments that your language was worth teaching at the university level. And after that, one still needed a critical mass of students to agree it was worth spending their time and tuition to learn your language. Which probably meant that one needed a critical mass of corporations to agree they wanted their employees to use your language. It was a tall order that took years if one was lucky, and only some languages — FORTRAN, PL/I, C, Java, and Python come to mind — managed to succeed on all of these fronts. But that was then, this is now. Whip up some online materials, and you can kiss your textbook publishing worries goodbye. Manage to convince just one of the new Super Profs at Udacity or Coursera to teach your programming language, and they can reach 160,000 students with just one free, not-for-credit course. And even if the elite Profs turn up their nose at your creation, upstarts like Khan Academy or Code Academy can also deliver staggering numbers of students in a short time. In theory, widespread adoption of a new programming language could be achieved in weeks instead of years or decades, piquing employers' interest. So, could we be on the verge of a programming language renaissance? Or will the status quo somehow manage to triumph?"

Paid Media Must Be Disclosed In Oracle v. Google 165

jfruh writes "One of the odder moments during the Oracle v. Google trial over Java patents came when patent blogger Florian Mueller disclosed that he had a 'consulting relationship' with Oracle. Now it looks like we're going to find out which other tech bloggers and journalists were on the payroll of one of the two sides in this epic fight. Judge William Alsup has ordered (PDF) that both parties disclose 'all authors, journalists, commentators or bloggers who have reported or commented on any issues in this case and who have received money (other than normal subscription fees) from the party or its counsel during the pendency of this action.'"

Curiosity Lands On Mars 411

The Mars Science Laboratory, a.k.a. Curiosity, is now less than an hour from touchdown on Mars. It's scheduled to land at 1:31 AM EDT (0531 UTC). The landing will be monitored by the Odyssey orbiter, which will be the data relay between Curiosity and Earth. The Mars Reconnaissance Orbiter will be listening to Curiosity as well (yes — two of our probes orbiting another world will be watching a third). While Odyssey will be giving us close to real-time updates (as close as possible, given the 14-minute time delay), MRO's data will take a bit longer to be processed and evaluated. NASA is broadcasting from the JPL mission room right now. If you'd like to watch a pretty awesome graphical visualization of the mission, check out eyes.nasa.gov. If you'd like to play around with a Java app showing Mars-local times and seasons, check out Mars24. If you'd like to watch unofficial coverage, Bad Astronomer Phil Plait and a bunch of other astronomers are hosting a public Google Hangout. If you'd like to read a detailed explanation of the landing, checkout NASA's press kit (PDF), and there's also a post about what to expect when the rover starts sending pictures back to Earth, which will be about two hours after the rover lands. Good luck to everyone involved! We'll update this post when we get word on the landing.
Update: 08/06 05:33 GMT by S : Curiosity is on the ground! Everything looks nominal, and everybody at JPL is cheering. Congratulations, folks. They're continuing to receive telemetry from Odyssey, and the connection is strong. They've now received the first images back from Mars of Curiosity on the ground. A press briefing is scheduled in a little bit (2:15AM EDT, 0615 UTC), and several more throughout the day as more data comes back.

Web Exploit Found That Customizes Attack For Windows, Mac, and Linux 204

phaedrus5001 writes with this quote from Ars: "Security researchers have found a live Web exploit that detects if the target is running Windows, Mac OS X, or Linux and drops a different trojan for each platform. The attack was spotted by researchers from antivirus provider F-Secure on a Columbian transport website, presumably after third-party attackers compromised it. The unidentified site then displayed a signed Java applet that checked if the user's computer is running Windows, Mac OS X, or Linux. Based on the outcome, the attack then downloads the appropriate files for each platform."

Objective-C Overtakes C++, But C Is Number One 594

mikejuk writes "Although the TIOBE Index has its shortcomings, the finding that Objective-C has overtaken C++ is reiterated in the open source Transparent Language Popularity Index. The reason is, of course, that Objective-C is the language you have to use to create iOS applications — and as iPads and iPhones have risen in popularity, so has Objective-C. If you look at the raw charts then you can see that C++ has been in decline since about 2005 and Objective-C has shot up to overtake it with amazing growth. But the two charts are on different scales: if you plot both on the same chart, you can see that rather than rocketing up, Objective-C has just crawled its way past, and it is as much to do with the decline of C++. It simply hasn't reached the popularity of C++ in its heyday before 2005. However the real story is that C, a raw machine independent assembler-like language, with no pretense to be object oriented or sophisticated, has beaten all three of the object oriented heavy weights — Java, C++ and Objective C. Yes C is number one (and a close second in the transparent index)."

Leap Second Bug Causes Crashes 230

An anonymous reader writes in with a Wired story about the problems caused by the leap second last night. "Reddit, Mozilla, and possibly many other web outfits experienced brief technical problems on Saturday evening, when software underpinning their online operations choked on the “leap second” that was added to the world’s atomic clocks. On Saturday, at midnight Greenwich Mean Time, as June turned into July, the Earth’s official time keepers held their clocks back by a single second in order to keep them in sync with the planet’s daily rotation, and according to reports from across the web, some of the net’s fundamental software platforms — including the Linux operating system and the Java application platform — were unable to cope with the extra second."

Windows 8: .NET Versus HTML5 Metro App Development 179

An anonymous reader writes "Will Microsoft take advantage of .NET's Java-like CIL and allow .NET code to run on Windows 8, or force developers to switch to HTML5 Metro apps instead for porting apps to Windows 8? This article brings up important insights into both paradigms' advantages and disadvantages, and even correlates the options with Microsoft's past NT-era support of MIPS and PPC, as well as Windows CE's way of supporting embedded architectures."

In recent years, I've worked for computer software vendors doing pre-sales support generally for infrastructure products including applications, app servers, integration with Java based messaging and ESB product and most recently a Business Rules product. I was laid off recently due to a restructuring and am now trying to figure out the next phase. With the WIA displaced worker grants now available I am attempting to figure out what training would be good to pursue.

Oracle's Ellison Vows "Most Comprehensive Cloud On Earth" 78

CWmike writes "Oracle CEO Larry Ellison declared the company is ready to offer 'the most comprehensive cloud on the planet Earth,' during a webcast event on Wednesday. 'It's been a long time coming,' Ellison said of the Oracle Public Cloud, which encompasses Oracle's suite of Fusion Applications delivered as both SaaS (software as a service) and PaaS (platform as a service) features, including the Java Cloud Service and Database Cloud Service. It's also the home of Oracle Social Network, the company's foray into Facebook-like collaboration tools for enterprises. Wednesday's event — and Twitter (where his first tweet is a gem) — also provided Ellison with an opportunity to tout what he called Oracle Public Cloud's many advantages over rivals such as SAP and Salesforce.com, as well as to engage in some of his traditional competitive trash talk."

Book Review: Elemental Design Patterns 129

jkauzlar writes "Believe it or not, it's been 18 years since Design Patterns by Gamma, et al, first began to hit the desks of programmers world-wide. This was a work of undeniable influence and usefulness, but there is criticism however that pattern-abuse has lead to over-architected software. This failure is perhaps due to wide-spread use of patterns as templates instead of understanding their underlying 'grammar' of this language such that it may be applied gracefully to the problem at hand. What's been missing until now is a sufficiently authoritative study of design patterns at this 'grammatical' level of abstraction. Jason McC. Smith, through a surprisingly captivating series of analytic twists and turns, has developed a theory of Elemental Design Patterns that may yet rejuvenate this aging topic."

Ask Slashdot: Tips For Designing a Modern Web Application? 409

New submitter sdoca writes "I am a Java developer and for the past number of years I have mainly been working on server side code. I have an idea for a webpage/application that I would like to develop. For the general public, it will be a site where they can view upcoming events, filter them by type, date etc. and view details of events they're interested in. There will also be an admin section to the app where organizations who want to post their events can log in and set them up. In the long term, writing a view-only version as an Apple and/or Android app is on the radar, but I want to focus on the generic web app for now. I'm not sure what languages/frameworks to look at using for the webpage portion of my project. Many (many!) years ago, I wrote some applets. After that I did some work in WebObjects and after that I tinkered with Wicket. I have no experience with PHP and would like to stay in my Java comfort zone as much as possible, but want to use the right tool. I'm concerned about browser compatibility issues. Chrome didn't exist when I last did web page development. I'm looking for good resources (books, internet) that will guide me through the potential issues and your recommendations for a web development framework."

I am a native English speaker from Canada though. The only jobs I've had any responses from were teaching positions for simple English which isn't exactly my first choice.

No Patent Infringement Found In Oracle vs. Google 234

sl4shd0rk writes "Today, the jury in the Oracle vs. Google trial found no infringement of patents by Google. The jury deliberated about 30 minutes to reach the verdict, bringing an end to the second phase of the trial, and a beginning to the damage phase, which may be very little of what Oracle originally asked for. Still no word on API copyright issues. Judge Alsup will be ruling on that in the near future, and it will certainly have an impact on the developer community."

Judge to Oracle: A High Schooler Could Write rangeCheck 478

mikejuk writes with an update on the Oracle vs Google Trial. From the article: "One month into the Oracle v Google trial, Judge William Alsup has revealed that he has, and still does, write code. Will this affect the outcome? I think so! After trying to establish that the nine lines in rangeCheck that were copied saved Google time in getting Android to market the lawyer making the case is interrupted by the judge which indicates he at least does understand how straightforward it would be to program rangeCheck from scratch: 'rangeCheck! All it does is make sure the numbers you're inputting are within a range, and gives them some sort of exceptional treatment. That witness, when he said a high school student could do it — ' And the lawyer reveals he doesn't: 'I'm not an expert on Java — this is my second case on Java, but I'm not an expert, and I probably couldn't program that in six months.' Perhaps every judge should be a coding judge — it must make the law seem a lot simpler..." From yesterday; the Oracle lawyer was attempting to argue that Google profited by stealing rangeCheck since it allowed them to get to market faster than they would have had they wrote it from scratch. Groklaw, continuing its detailed coverage as always, has the motions filed today.

Ask Slashdot: Best Degree For a Late Career Boost? 234

Qbertino writes "I'm in my early 40s, and after a little more than 10 years of web, scripting and software development as a freelancer and some gigs as a regular, full-time employee, I'm seriously considering giving my IT career a boost by getting a degree. I'm your regular 1980s computer kid and made a career switch to IT during the dot-bomb days. I have quite a bit of programming and project experience, but no degree. I find myself hitting somewhat of a glass ceiling (with maybe a little age discrimination thrown in there). Since I'm in Germany, degrees count for a lot (70% of IT staff have a degree) so getting one seems fitting and a nice addition to my portfolio. However, I'm pondering wether I should go for Computer Science or Business Informatics. I'd like to move into Project Management or Technical Account Management, which causes my dilemma: CS gives me the pro credibility and proves my knowledge with low-level and technical stuff, and I'd be honing my C/C++ and *nix skills. Business Informatics would teach me some bean-counting skills; I'd be doing modelling, ERP with Java or .NET all day. It would give me some BA cred, but I'd lose karma with the T-shirt wearing crew and the decision-makers in that camp. I'm leaning toward Business Informatics because I suspect that's where the money is, but I'm not quite sure wether a classic CS degree wouldn't still be better — even if I'm wearing a suit. Any suggestions?"

Oracle Not Satisfied With Potential $150,000; Goes Against Judge's Warning 234

bobwrit writes with news about how the monetary damages in the Google v. Oracle case might shake out. On Thursday, Judge Alsup told Oracle the most it could expect for statutory damages was a flat $150,000, a far cry from the $6.1 billion Oracle wanted in 2011, or even the $2.8 million offered by Google as a settlement. However, Oracle still thinks it can go after infringed profits, even though Judge Alsup specifically warned its lawyers they were making a mistake. He said, "It's the height of ridiculousness to say for those 9 lines you get hundreds of millions." Groklaw has a detailed post about today's events.
