jtotheh writes "According to the Register, Oracle is going to make two tiers of Java Virtual Machine — a free one and a premium paid one. 'Adam Messinger, Oracle vice president of development, told QCon that Oracle plans to offer a "premium" edition of the JDK in addition to the open-source JDK. Both, it seems, will be based on a converged JRockit VM and the Hotspot JVM from Sun Microsystems. The converged JVM will be released under the OpenJDK project. ... Messinger didn't explain how the premium JVM would differ [from] the free version, but the premium edition will likely see performance tuning and tie-ins to Oracle's middleware.'"

Two9A writes "JavaScript has shed its image of being a limited language, tied to DOM manipulation in a browser; in recent years, new engines and frameworks have given JS a reputation as a language capable of bigger things. Mix this in with the new elements of HTML5, and you have the capacity to emulate a game console or other system, with full graphical output. This series of articles looks in detail at how an emulator is written in JavaScript, using the example of the Gameboy handheld: starting at the CPU, and (as of part 8) running a copy of Tetris."

aabelro writes "Don Syme has announced the release of the F# compiler source code as a code drop under Apache 2.0. He wrote, 'The F# PowerPack now includes libraries, tools and the compiler/library source code drops. I'd like to take a moment to explain the F# team's approach to this. Firstly, the source for the F# compiler in our MSI/CTP releases has been available for some time, in the releases themselves, so in that sense there's not much new in this release. Secondly, we've always made sure we have a free download binary release of F# available, and will continue to do that, and that should still be the main way you "get" a release of F#. However, we've long discussed making compiler+library source available in a different way. After some discussion, we've decided to do this via a "code drop" model, where we make available versions of the compiler+library code logically matching each release of the F# language itself.'"

s1axter writes with word that "the data log format for the Tesla Roadster has been reverse engineered and documented, now available in Python. (Python script linked in the post.)" From the linked blog entry: "Not only was I given a $110k car unrestricted I was requested to see what ECU information is available, collect and parse the data from it. Tesla Motors periodically collects information from their vehicles presumably to see what real-world driving the cars see. On original Roadster models there is no method to collect this information remotely thus someone must go out to the vehicle and collect it. The owner of the vehicle saw this and wanted to know what information was collected on these service calls ... Because I am a big fan of freedom to modify a program to fit ones needs, I have uploaded the ... python script to parse Tesla logs."

theodp writes "Oracle said HP has refused to accept a subpoena requiring new CEO Leo Apotheker to testify in a trial against his former employer SAP, which will determine how much SAP owes Oracle for copyright infringement by its discontinued TomorrowNow unit. 'Mr. Apotheker started work for HP on Monday, but it now appears that the HP board of directors has decided to keep him away from HP's headquarters and outside the court's jurisdiction,' an Oracle spokeswoman said. 'We will continue to try to serve him,' she added. An HP spokeswoman countered: 'Given Leo's limited knowledge of and role in the matter, Oracle's last-minute effort to require him to appear live at trial is no more than an effort to harass him and interfere with his duties and responsibilities as HP's CEO.' The spokeswoman declined to discuss the whereabouts of Mr. Apotheker, who was featured in a 2006 SAP/TomorrowNow press release attacking the 'uncertainty' of Oracle. Coincidentally, among the charges leveled at SAP/TomorrowNow was 'pretextual customer log-in,' an area in which HP has some subject matter expertise."

snydeq writes "InfoWorld offers a look back at the first decade of agile programming. Forged in February 2001 when a group of developers convened in Utah to find an alternative to documentation-driven, 'heavyweight' software development practices, The Manifesto for Agile Software Development sought to promote processes that accommodate changing requirements, collaboration with customers, and delivery of software in short iterations. Fast-forward a decade, and agile software development is becoming increasingly commonplace, with software firms adopting agile offshoots such as Scrum, Extreme Programming, and Kanban — a trend some see benefiting software development overall."

Jamie recommends a blog post from software engineer Louis Brandy explaining how using genetic algorithms to evaluate build orders in StarCraft 2 has led to some surprisingly powerful results. Quoting: "One of the reasons build-order optimization is so important is that you can discover openings that 'hard-counter' other openings. If I can get an army of N size into your base when you do opening X, you will always lose. ... a genetic algorithm is a type of optimization algorithm that tries to find optimal solutions using a method analogous to biologic evolution (to be specific: descent with modification & natural selection). Put simply, you take a 'population' of initial build orders, evaluate them for fitness, and modify the population according to each element’s fitness. In other words, have the most successful reproduce. The program’s input is simply the desired game state. In practice, this means 'make N units' to determine some rush build order (but it also allows for other types of builds, like make N workers with some defensive structures and a small army)."

A couple weeks ago, we discussed news that some Facebook application developers were selling or accidentally sharing user IDs to advertisers and data brokers in violation of Facebook's privacy terms. Now, the company writes that they've updated the policy to dictate how UIDs can be handled within applications, and also punished the offending developers by blocking access to the site's communication channels for a period of six months. Quoting: "While we determined that no private user data was sold and confirmed that transfer of these UIDs did not give access to any private data, this violation of our policy is something we take seriously. As such, we are taking action against these developers by instituting a 6-month full moratorium on their access to Facebook communication channels, and we will require these developers to submit their data practices to an audit in the future to confirm that they are in compliance with our policies. This impacts fewer than a dozen, mostly small developers, none of which are in the top 10 applications on Facebook Platform. We have also reached an agreement with Rapleaf, the data broker who came forward to work with us on this situation. Rapleaf has agreed to delete all UIDs in its possession, and they have agreed not to conduct any activities on the Facebook Platform (either directly or indirectly) going forward."

dkd903 writes "We all knew it would come to this, and it has finally happened — 33 developers have left OpenOffice.org to join The Document Foundation, with more expected to leave in the next few days. After Oracle acquired Sun Microsystems, OpenOffice.org fell into the hands of Oracle, as did a lot of other products. So, last month a few very prominent members of the OpenOffice.org community decided to form The Document Foundation and fork OpenOffice.org as LibreOffice, possibly fearing that it could go the OpenSolaris way."

theodp writes "To move forward with programming languages, argues Poul-Henning Kamp, we need to break free from the tyranny of ASCII. While Kamp admires programming language designers like the Father-of-Go Rob Pike, he simply can't forgive Pike for 'trying to cram an expressive syntax into the straitjacket of the 95 glyphs of ASCII when Unicode has been the new black for most of the past decade.' Kamp adds: 'For some reason computer people are so conservative that we still find it more uncompromisingly important for our source code to be compatible with a Teletype ASR-33 terminal and its 1963-vintage ASCII table than it is for us to be able to express our intentions clearly.' So, should the new Hello World look more like this?"

An anonymous reader writes "A proposal has been brought up with KDE developers by Cornelius Schumacher to merge the KDE libraries with the upstream Qt project. This could potentially lead to KDE5 coming about sooner than anticipated, but there's very mixed views on whether merging kdelibs with Qt would actually be beneficial to the KDE project, which has already led to two lengthy mailing list talks (the first and second threads). What do you think?"

Andrew Smith writes "John Carmack has an article up on the Bethesda blog discussing the iPhone/iPad version of RAGE, which is said to run at an impressive 60fps. 'Managing over a gig of media made dealing with flash memory IO and process memory management very important, and I did a lot of performance investigations to figure things out. Critically, almost all of the data is static, and can be freely discarded. iOS does not have a swapfile, so if you use too much dynamic memory, the OS gives you a warning or two, then kills your process. The bane of iOS developers is that "too much" is not defined, and in fact varies based on what other apps (Safari, Mail, iPod, etc) that are in memory have done. If you read all your game data into memory, the OS can’t do anything with it, and you are in danger. However, if all of your data is in a read-only memory mapped file, the OS can throw it out at will.' And a tweet by Carmack yesterday suggests that an Android version of RAGE is on the way too."

An anonymous reader writes "It looks like Microsoft might finally be realizing that Silverlight can't cover every platform, according to this conversation with Bob Muglia: '... when it comes to touting Silverlight as Microsoft’s vehicle for delivering a cross-platform runtime, "our strategy has shifted," Muglia told [ZDNet]. Silverlight will continue to be a cross-platform solution, working on a variety of operating system/browser platforms, going forward, he said. "But HTML is the only true cross platform solution for everything, including (Apple's) iOS platform," Muglia said.'"

eldavojohn writes "As anyone in the industry will tell you, a lot of money went into developing web applications specific to IE6. And corporations can't leave Windows XP for Windows 7 until IE6 runs (in some way) on Windows 7. Microsoft wants to leave that non-standard browser mess behind them, but as the article notes, 'Organizations running IE6 have told Gartner that 40% of their custom-built browser-dependent applications won't run on IE8, the version packaged with Windows 7. Thus, many companies face a tough decision: Either spend time and money to upgrade those applications so that they work in newer browsers, or stick with Windows XP.' Support for XP is going to end in April 2014. In order to deal with this, companies are looking at virtualizing IE6 only (instead of a full operating system) so that it can run on Windows 7 — even though Microsoft says this violates licensing agreements. IE6 is estimated to have roughly 16% of browser market share, and due to mistakes in the past it may never truly die."

itwbennett writes "On Wednesday, Oracle amended the lawsuit it filed against Google in August, saying that 'approximately one third of Android's Application Programmer Interface (API) packages' are 'derivative of Oracle's copyrighted Java API packages' and related documents. In particular, 'the infringed elements of Oracle America's copyrighted work include Java method and class names, definitions, organization, and parameters; the structure, organization and content of Java class libraries; and the content and organization of Java's documentation,' Oracle says. 'In at least several instances, Android computer program code also was directly copied from copyrighted Oracle America code,' Oracle alleges."

The Contrarian writes "It looks like Oracle is not suiting former Sun staff well, nor community members in the Java and OpenOffice.org communities. This weekend saw an unusually large number of rather public departures, with (among many others listed in the article) the VP running Solaris development quitting, the token academic on the JCP walking out and top community leaders at OpenOffice.org nailing their resignations to the door after having the ex-Sun people slam it in their face. The best analysis comes from an unexpected place, with the marketing director of Eclipse — usually loyal defenders of their top-dollar-paying members — turning on Oracle and telling them to get a clue."

Ponca City writes "Until now, computer security has been reactive. 'Our defenses improve only after they have been successfully penetrated,' says security expert Fred Schneider. But now Dr. Dobb's reports that researchers at Cornell are developing a programming platform called 'Fabric,' an extension to the Java language that builds security into a program as it is written. Fabric is designed to create secure systems for distributed computing, where many interconnected nodes — not all of them necessarily trustworthy — are involved, as in systems that move money around or maintain medical records. Everything in Fabric is an 'object' labeled with a set of policies on how and by whom data can be accessed and what operations can be performed on it. Even blocks of program code have built-in policies about when and where they can be run. The compiler enforces the security policies and will not allow the programmer to write insecure code (PDF). The initial release of Fabric is now available at the Cornell website."

eldavojohn writes "Recent research on bumble bees has proven that the tiny bee is better than computers at the traveling salesman problem. As bees visit flowers to collect nectar and pollen they discover other flowers en route in the wrong order. But they still manage to quickly learn and fly the optimally shortest path between flowers. Such a problem is NP-Hard and keeps our best machines thinking for days searching for a solution but researchers are quite interested how such a tiny insect can figure it out on the fly — especially given how important this problem is to networks and transportation. A testament to the power of even the smallest batch of neurons or simply evidence our algorithms need work?"

theodp writes "Think outside the box? Nah, think outside the bun. Ted Dziuba argues there's a programming lesson to be learned from observing how Taco Bell manages to pull down $1.9 billion by mixing-and-matching roughly eight ingredients: 'The more I write code and design systems, the more I understand that many times, you can achieve the desired functionality simply with clever reconfigurations of the basic Unix tool set. After all, functionality is an asset, but code is a liability. This is the opposite of a trend of nonsense called DevOps, where system administrators start writing unit tests and other things to help the developers warm up to them — Taco Bell Programming is about developers knowing enough about Ops (and Unix in general) so that they don't overthink things, and arrive at simple, scalable solutions.'"
