Eclipse Launches New Programming Language 238

Posted by timothy from the onslaught-of-new-languages dept.
An anonymous reader writes "Eclipse has launched a website for a new JVM language, called Xtend. It's built with Eclipse's Xtext and compiles directly to Java code, similar to what CoffeeScript does to Javascript. It's not just an announcement but it's already there and useable, including a very feature-rich Eclipse integration."

Ask Slashdot: When and How To Deal With GPL Violations? 151

Posted by Soulskill from the stop-or-i'll-say-stop-again dept.
jd writes "There are many pieces of software out there, such as seL4 (kindly brought to my attention by another reader), where the vendor has indeed engineered something that they're entitled to Close Source, but where their closed-source license includes the modifications to GPLed software such as the Linux kernel. Then there's a second type of behavior. Code Sourcery produced two versions of their VSIPL++ image processing library — one closed-source, one GPLed. It was extremely decent of them. When Mentor Graphics bought Code Sourcery, they continued developing the closed-course one and discontinued, then deleted, the GPL variant. It's unclear to me if that's kosher, as the closed variant must contain code that had been GPLed at one point. Here's the problem: complaining too much will mean we get code now that maybe four or five people, tops, will actually care about. It will also make corporations leery of any other such work in future, where that work will be of greater value to a greater number of people. So, the question I want to ask is this: When is it a good time to complain? By what rule-of-thumb might you decide that one violation is worth cracking down on, and another should be let go to help encourage work we're never going to do ourselves?"

Apache Harmony Moves To Apache Attic 120

Posted by Soulskill from the giving-up-the-ghost dept.
think_nix writes "After the resignation of Apache from the Java SE/EE Executive Committee, the time has now come for Harmony to be added to the Apache Attic. Harmony was 'the project to produce an open source cleanroom implementation of Java.' An open vote was taken within the Project Management Committee, which resulted in a 20-2 majority to discontinue development."

Is SaaS Killing Native Linux App Development? 330

Posted by Soulskill from the won't-somebody-think-of-the-penguins dept.
jfruhlinger writes "In a world where 'app' is the new buzzword, the development of native Linux apps is lagging. Some of this can be attributed to the usual community infighting (the latest version of which is argument about Ubuntu's Unity interface), but there may be something deeper at play: Linux advocates have for so long advocated browser-accessed software as a service as a way to break out of Microsoft's proprietary desktop. Now that this world has arrived, there's less incentive to work on native Linux apps. But of course, entrusting your functionality and data to a cloud provider like Google has its own set of concerns for free software fans."

Pancake Flipping Is Hard — NP Hard Screenshot-sm 260

Posted by samzenpus from the sorting-a-large-stack dept.
mikejuk writes "French computer scientists have finally proved that sorting pancakes is hard — NP hard. No really — this isn't a joke. Well, it is slightly amusing but that's just because it is being presented as pancake flipping. The algorithm in question is sorting a permutation using prefix reversal — which is much easier to understand in terms of pancakes. Basically you have to sort a pancake stack by simply inserting your spatula and flipping the top part of the stack. We now know that if you can do the this in polynomial time then you have proved that P=NP."

Tough Tests Flunk Good Programming Job Candidates 743

Posted by samzenpus from the lowering-the-bar dept.
snydeq writes "Fatal Exception's Neil McAllister discusses the use of quizzes and brain-teasers in evaluating potential software development hires, a practice that seems to be on the rise. 'The company best known for this is Google. Past applicants tell tales of a head-spinning battery of coding problems, riddles, and brain teasers, many of which seem only tangential to the task of software development. Other large companies have similar practices — Facebook and Microsoft being two examples,' McAllister writes. 'You'll need to assess an applicant's skill in one way or another, but it's also possible to take the whole interview-testing concept too far. Here are a few thoughts to keep in mind when crafting your test questions, to avoid slamming the door on candidates unnecessarily.'"

Open Source Eclipse Celebrates 10th Birthday 90

Posted by samzenpus from the they-grow-up-so-fast dept.
msmoriarty writes "10 years ago this month, IBM open sourced an internal project focused on creating a common component framework for developers: Eclipse. In an interview with ADTmag.com, Eclipse Foundation director Mike Milinkovich remarks on what was, back then, a revolutionary move: 'You've got to give IBM a lot of credit...Ten years ago, the notion that open source might be the best way for software vendors to collaborate was really a novel idea... Eclipse demonstrated the advantages of collaboration in open source, even amongst fierce competitors.' The Eclipse Foundation is celebrating the anniversary with a kickoff party at its EclipseCon Europe 2011 conference, and if you're an Eclipse community member, the Foundation is also inviting you to add yourself to the Eclipse 10th Birthday Timeline."

Is the Apple App Store a Casino? 542

Posted by Unknown Lamer from the dulcinea's-life-makes-ten-billion dept.
An anonymous reader writes "Fast Company takes a look at the Apple App Store and concludes that it's a casino where most developers are making tragic losses and a tiny few are striking it filthy rich. The article discusses a new book exposing the App Store millionaires, called 'Appillionaires,' which compares the psychological effects of a hit app on a programmer to a gambler's high. One millionaire programmer explains the intense feeling of being in the top-ten: 'The App Store had established some kind of intravenous connection to my body and was pumping me full of Apple-branded heroin.' But, the piece warns, the majority of developers fail to make any return on their app."

Things That Turbo Pascal Is Smaller Than 487

For starters, at 39,731 bytes, the entire Turbo Pascal 3.02 executable (compiler and IDE) makes it less than 1/4th the size of the image of the white iPhone 4S at apple.com (190,157 bytes), and less than 1/5th the size of the yahoo.com home page (219,583 bytes). Speaking of slim-and-trim software, Visicalc, the granddaddy of all spreadsheet software which celebrated its 32nd birthday this year, weighed in at a mere 29K."

Ask Slashdot: Learning Dart Development? 107

Posted by timothy from the oh-dartlang-we-can't-go-on-like-this dept.
First time accepted submitter gmikeska07 writes "I have no computer science degree, but I took a Java class in college and greatly enjoyed it. I have some experience with Javascript and have done some perl programming as well. I would like to learn Google's forthcoming Dart language. My question is in three parts: a) Is there any chance that if I self-teach Dart, I can get a job in development without a CS degree, once companies begin using the language? b) Is it really worth installing Virtual Studio as per the dartlang docs, or should I wait for a dedicated IDE like the rumored 'Brightly'? Alternatively, are there any solid open development environments that are adding support? c) Do you know of any books that are out or on the way that I could buy? What programming series do you guys recommend? Hopefully I can learn in my spare time, and if I can't get a job in development I can at least have fun with it, and maybe make a few libraries for the Dart community!"

Rethinking the Nature of Files 369

Posted by timothy from the files-are-inside-the-computer dept.
An anonymous reader writes "Two recent papers, one from Microsoft Research and one from University of Wisconsin (PDF), are providing a refreshing take on rethinking 'what a file is.' This could have major implications for the next-gen file system design, and will probably cause a stir among Slashdotters, given that it will affect the programmatic interface. The first paper has some hints as to what went wrong with the previous WinFS approach. Quoting the first paper: 'For over 40 years the notion of the file, as devised by pioneers in the field of computing, has proved robust and has remained unchallenged. Yet this concept is not a given, but serves as a boundary object between users and engineers. In the current landscape, this boundary is showing signs of slippage, and we propose the boundary object be reconstituted. New abstractions of file are needed, which reflect what users seek to do with their digital data, and which allow engineers to solve the networking, storage and data management problems that ensue when files move from the PC on to the networked world of today. We suggest that one aspect of this adaptation is to encompass metadata within a file abstraction; another has to do what such a shift would mean for enduring user actions such as "copy" and "delete" applicable to the deriving file types. We finish by arguing that there is an especial need to support the notion of "ownership" that adequately serves both users and engineers as they engage with the world of networked sociality. '"

Ask Slashdot: Best EEPROM Programmer For a Hobbyists? 165

Posted by Soulskill from the getting-technical dept.
BigSes writes "I had been in the amusement repair industry (video gaming, pinball, jukeboxes, etc) for more than a decade, but have recently taken a new career path. I still greatly enjoy tinkering with all the electronics, and collect many arcade games and pinball machines for my home. I always had access to EEPROM / PROM / PIC / GAL programmers on the job, but never owned one personally. I'm finding it difficult to work within my chosen hobby without one, and ordering pre-programmed chips can be cost prohibitive for some projects. I would love it if some of you professionals or other hobbyists out there could recommend a great programmer that supports a large number of chip formats for me to use. I'd like it to be something USB, more modern than Serial or Parallel port (usually what we had in the old days) and preferably sub-$300, new or used. There are tons of Chinese import types on eBay, but I'd hate to spend $80+ if I am unsure of the quality."

Career Advice: Don't Call Yourself a Programmer 422

Posted by Soulskill from the be-a-leveraged-syngeristic-cloud-solution-instead dept.
Ian Lamont writes "Patrick McKenzie has written about the do's and don't's of working as a software engineer, and some solid (and often amusing) advice on how to get ahead. One of the first pieces of advice: 'Don't call yourself a programmer: "Programmer" sounds like "anomalously high-cost peon who types some mumbo-jumbo into some other mumbo-jumbo." If you call yourself a programmer, someone is already working on a way to get you fired.' Although he runs his own company, he is a cold realist about the possibilities for new college grads in the startup world: 'The high-percentage outcome is you work really hard for the next couple of years, fail ingloriously, and then be jobless and looking to get into another startup.'"

Stanford's Open Source Human Motion Software 15

Posted by Soulskill from the defining-the-mathematically-perfect-swagger dept.
eldavojohn writes "Stanford's OpenSim software is a human motion modeling package that is currently making the rounds at museums where 'visitors walk across a pressure-sensitive floor and are presented at the other side with color-coded print outs of their weight distribution, identifying even slight imbalances that might be putting undue stress on their limbs and joints.' This project can also help with planning surgery (video). The work has been published in IEEE Transactions on Biomedical Engineering (note that this is a different effort from the virtual world of the same name). Although Stanford's press release says it is now open source, I cannot find what license they are using, nor can I access their SVN browser after registering."

Oracle-Google Trial Won't Start Until Next Year 60

Posted by samzenpus from the wheels-of-justice-turn-slowly dept.
angry tapir writes "The intellectual property lawsuit between Oracle and Google over the Android mobile OS won't go to trial until next year, according to a ruling made in the U.S. District Court for the Northern District of California by the judge overseeing the case. The trial was initially set to begin Oct. 31 but was postponed last week by Judge William Alsup due to scheduling conflicts with a major criminal trial. The trial will be split into three stages heard by the same jury. In step one, 'liability on the copyright claims, including all defenses thereto, will be tried and determined by special verdict before going to Phase Two,' he wrote. The second phase will cover liability on the case's patent claims, he added. 'The jury will decide these issues before going to Phase Three.' In the final stage, 'all remaining issues will be tried, including damages and willfulness.'"

Analysis of Google Dart 171

Posted by Unknown Lamer from the google-announces-replacement-for-english dept.
An anonymous reader writes "Google's new language landed with a loud thud, causing lots of interesting debates about the best place to stick semicolons... An article [in InfoQ] ... looks at some of the less discussed features. Snapshots seem to bring something like Smalltalk images and allow instant startup of applications (something Java has spent the last 15 years not delivering). Isolates are like OS processes and communicate with message passing — and as the article suggests, can fix the problem of Garbage Collection pauses by splitting up the heap (sounds like Erlang). There's more, mostly about features that remove some dynamic behavior in order to make startup and code analysis easier. Maybe Dart is worth a second look?"
