eldavojohn writes "A number of blog posts are surfacing that are calling out the helpful open source community on their documentation. No, not the documentation for the highly skilled technical people, but the documentation from beginner to apprentice. A two-part series by Carla Schroeder lists bad documentation as 'Linux Bug #1' and advises users to use Google as the documentation. We've discussed before some of open source's documentation being out of date. Is it really as bad as these blogs paint it? Has it come down to using Google before a man page?"

Martijn de Boer writes "The book has been written to provide the reader with a short introduction to the concepts of Service Oriented Architecture with Java. The book covers the theory and analysis from the start and is progressing to a more intermediate level slowly throughout the different chapters. This book has been written for software architects and programmers of the Java language who have an interest in building software using SOA concepts in their applications. The cover hints to a series called “From Technologies to Solutions”, and that is exactly what this book tries to do, it tries to explain the SOA technology with different case studies and a path for solutions for your applications." Read below for the rest of Martijn's review.

eldavojohn writes "If you think JavaScript is a crime against humanity, you might want to skip this article, because Ars is reporting on efforts to take JavaScript to the next level. With the new ECMAScript 5 draft proposal, the article points out a lot of positive things that have happened in the world of JavaScript. The article does a good job of citing some of the major problems with JavaScript and how a reborn library called CommonJS (formerly ServerJS) is addressing each of those problems. No one can deny JavaScript's usefulness on the front end of the web, but if you're a developer do you support the efforts to move it beyond that?"

Lawand writes "Nokia today released Qt 4.6, the latest version of the cross-platform application and UI framework. Featuring new platform support, powerful new graphical capabilities and support for multi-touch and gestures, and this is the first release to include significant code contributed from the community. This release introduces support for the Symbian platform with integration for the S60 framework, expanding the addressable market for Qt applications by over 130 million Symbian devices."

Ponca City, We love you writes to tell us that a new software approach to police sketch artists is finding surprising success in a trial run of 15 police departments in the UK and a few other sites. The software borrows principles from evolution with an interactive genetic algorithm that progressively changes as witnesses try to remember specific details. Current field trials are reporting an increase in successful identification by as much as double conventional methods. A short video with a few working shots of the new "EFIT-V" system is also available on YouTube. "[Researcher Christopher Solomon]'s software generates its own faces that progressively evolve to match the witness' memories. The witness starts with a general description such as 'I remember a young white male with dark hair.' Nine different computer-generated faces that roughly fit the description are generated, and the witness identifies the best and worst matches. The software uses the best fit as a template to automatically generate nine new faces with slightly tweaked features, based on what it learned from the rejected faces. 'Over a number of generations, the computer can learn what face you're looking for,' says Solomon. The mathematics underlying the software is borrowed from Solomon's experience using optics to image turbulence in the atmosphere in the 1990s."

Charbax writes "While Archos' current 'Archos 5 Internet Tablet with Android' is a 4.8" WVGA tablet that runs Android 1.5 (and perhaps 2.0 soon with the full Google Marketplace Experience), users of last year's 4.8" and 7" Archos Linux tablets have been complaining that Archos' firmware updates to its proprietary, embedded Linux OS were too infrequent, and added too little of the requested functionality. Under pressure from hackers demonstrating jailbreak methods, Archos has just now officially released (PDF) the open-source Special Developer Edition firmware based on Angstrom Linux, generated from a customized, open embedded build for last year's Archos 5 and 7 Internet Media tablets. If many talented developers join the community of Archos hackers to make software for this new Archos SDE firmware, then Android, Angstrom Linux, Maemo Mer, Qt and Ubuntu Linux could be expected to run smoothly on it soon. That could make it the ultimate pocket Linux Internet tablet for Linux hackers. Installing Archos' new SDE firmware permanently disables DRM playback and voids the warranty."

ericatcw writes "Through tools such as Visual Basic and Visual Studio, Microsoft may have done more than any other vendor to make drag and drop-style programming mainstream. But its superstar developers seem to prefer old-school modes of crafting code. During the panel at the Professional Developers Conference earlier this month, the devs also revealed why they think writing tight, bare-metal code will come back into fashion, and why parallel programming hasn't caught up with the processors yet." These guys are senior enough that they don't seem to need to watch what they say and how it aligns with Microsoft's product roadmap. They are also dead funny. Here's Jeffrey Snover on managed code (being pushed by Microsoft through its Common Language Runtime tech): "Managed code is like antilock brakes. You used to have to be a good driver on ice or you would die. Now you don't have to pump your brakes anymore." Snover also joked that programming is getting so abstract, developers will soon have to use Natal to "write programs through interpretative dance."

blee37 writes "Here is an excellent video demonstration of a new program developed by Qi Pan, a graduate student, and other researchers at the University of Cambridge. The 'ProFORMA' software constructs a 3D model of an object in real time from (commodity) webcam video. The user can watch the program deduce more pieces of the 3D model as the object is moved and rotated. The resulting graphics are of high quality."

RunRevKev writes "The unveiling of Revolution 4.0 has sparked a debate on ZDNet about whether programming is being dumbed down. The new version of the software uses an English-syntax that requires 90 per cent less code than traditional languages. A descendant of Apple's Hypercard, Rev 4 is set to '...empower people who would never have attempted programming to create successful applications.' ZDNet reports that 'One might reasonably hope that this product inspires students in the appropriate way and gets them more interested in programming.'"

An anonymous reader writes "The European Union has managed to do something that US Presidents often find difficult: to make 59 US Senators from both sides of the aisle agree on something. A group led by John Kerry (D) and Orrin Hatch (R) has sent a letter to the European Union, asking it to wrap up the investigation of the Oracle-Sun merger and let the deal go through. Interestingly, the letter emphasizes the damage the delay and uncertainty are doing to Sun." The article paraphrases a Gartner analyst, who points out that the Senators' letter "comes from a US point of view and doesn't take into account how the EU operates."

drroman22 writes "Schools are working to put real-world relevance into computer science education by integrating video game development into traditional CS courses. Quoting: 'Many CS educators recognized and took advantage of younger generations' familiarity and interests for computer video games and integrate related contents into their introductory programming courses. Because these are the first courses students encounter, they build excitement and enthusiasm for our discipline. ... Much of this work reported resounding successes with drastically increased enrollments and student successes. Based on these results, it is well recognized that integrating computer gaming into CS1 and CS2 (CS1/2) courses, the first programming courses students encounter, is a promising strategy for recruiting and retaining potential students." While a focus on games may help stir interest, it seems as though game development studios are as yet unimpressed by most game-related college courses. To those who have taken such courses or considered hiring those who have: what has your experience been?

An anonymous reader writes to tell us that finding malicious code might have just become a little harder. Last week at the ACM Conference on Computer and Communications Security, security researchers Joshua Mason, Sam Small, Fabian Monrose, and Greg MacManus presented a method they developed to generate English shell code [PDF]. Using content from Wikipedia and other public works to train their engine, they convert arbitrary x86 shell code into sentences that read like spam, but are natively executable. "In this paper we revisit the assumption that shell code need be fundamentally different in structure than non-executable data. Specifically, we elucidate how one can use natural language generation techniques to produce shell code that is superficially similar to English prose. We argue that this new development poses significant challenges for in-line payload-based inspection (and emulation) as a defensive measure, and also highlights the need for designing more efficient techniques for preventing shell code injection attacks altogether."

igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."

Ricky writes "Many wonder why Microsoft doesn't offer nightly builds of Internet Explorer — or at least something more frequent than months-to-years. Ars talks with Microsoft's general manager for IE, who says the IE9 development cycle will look much the same as previous versions. Not a great idea."

Hugh Pickens writes "The advantages of RISC are well known — simplifying the CPU core by reducing the complexity of the instruction set allows faster speeds, more registers, and pipelining to provide the appearance of single-cycle execution. Al Williams writes in Dr Dobbs about taking RISC to its logical conclusion by designing a functional computer called One-Der with only a single simple instruction — a 32-bit Transfer Triggered Architecture (TTA) CPU that operates at roughly 10 MIPS. 'When I tell this story in person, people are usually squirming with the inevitable question: What's the one instruction?' writes Williams. 'It turns out there's several ways to construct a single instruction CPU, but the method I had stumbled on does everything via a move instruction (hence the name, "Transfer Triggered Architecture").' The CPU is implemented on a Field Programmable Gate Array (FPGA) device and the prototype works on a 'Spartan 3 Starter Board' with an XS3C1000 device available from Digilent that has the equivalent of about 1,000,000 logic gates, costing between $100 and $200. 'Applications that can benefit from custom instruction in hardware — things like digital signal processing, for example — are ideal for One-Der since you can implement parts of your algorithm in hardware and then easily integrate those parts with the CPU.'"

wiedzmin writes "Facebook's Joe Hewitt, Second Gear's Justin Williams, the long-time Mac software developer known as 'Rogue Amoeba' and other respected App Store developers have recently decided to discontinue their work on the platform, citing their frustration with Apple's opaque approval process. Continued issues with erroneous and snap rejections of applications and APIs are prompting more and more developers to shun the platform entirely. Though there are tens of thousands of other developers who have pumped out over 100,000 apps for the platform, continued migration away from iPhone development will most likely result in lower quality software."

itwbennett writes "Pity the poor engineer who had to find this one. One of the more interesting of the handful of bugs that have appeared since the launch of Verizon's Droid smartphone has to do with the on-board camera's auto-focus. Apparently it just didn't work. And then suddenly it did. Naturally, this off-again, on-again made the theories fly. But the real reason for the bug was revealed in a comment on an Engadget post by someone claiming to be Google engineer Dan Morrill: 'There's a rounding-error bug in the camera driver's autofocus routine (which uses a timestamp) that causes autofocus to behave poorly on a 24.5-day cycle,' said Morrill. 'That is, it'll work for 24.5 days, then have poor performance for 24.5 days, then work again. The 17th is the start of a new 'works correctly' cycle, so the devices will be fine for a while. A permanent fix is in the works.'"

davecb writes "The ACM has been kind enough to print Paul Stachour's and my 'jack' article about Software Maintenance. Paul first pointed out back in 1984 that we and our managers were being foolish — when we were still running Unix V7 — and if anything it's been getting worse. Turns out maintenance has been a 'solved problem in computer science' since at least then, and we're just beginning to rediscover it."
