Call For Scientific Research Code To Be Released 505

Pentagram writes "Professor Ince, writing in the Guardian, has issued a call for scientists to make the code they use in the course of their research publicly available. He focuses specifically on the topical controversies in climate science, and concludes with the view that researchers who are able but unwilling to release programs they use should not be regarded as scientists. Quoting: 'There is enough evidence for us to regard a lot of scientific software with worry. For example Professor Les Hatton, an international expert in software testing resident in the Universities of Kent and Kingston, carried out an extensive analysis of several million lines of scientific code. He showed that the software had an unacceptably high level of detectable inconsistencies. For example, interface inconsistencies between software modules which pass data from one part of a program to another occurred at the rate of one in every seven interfaces on average in the programming language Fortran, and one in every 37 interfaces in the language C. This is hugely worrying when you realise that just one error — just one — will usually invalidate a computer program. What he also discovered, even more worryingly, is that the accuracy of results declined from six significant figures to one significant figure during the running of programs.'"

Game Development In a Post-Agile World 149

An anonymous reader writes "Many games developers have been pursuing agile development, and we are now beginning to witness the debris and chaos it has caused. While there have been some successes, there have also been many casualties. As the industry at large is moving away from the phantasmagoria of Agile, Gwaredd Mountain, Technical Director at Climax Studios, looks at Post-Agile and what this might mean for the games industry."

Oracle Drops Sun's Commitment To Accessibility 220

An anonymous reader writes "What I feared has come true: after buying Sun, Oracle had a look at its accessibility group and made big cuts in it by firing the most important contributors to the Linux accessibility tools. This is a very sad day for disabled people, as it means we do not really have full-time developers any more." The coverage in OSTATIC has a few more details, including the caution: "This just shows that all too few companies are sponsoring a11y work. If one company laying off a couple of developers spells trouble for the project, then there were problems before that happened" (thanks to reader dave c-b for pointing this out).

A Reflection On Sun Executive Payouts For Failure 316

With the Oracle/Sun merger finally completing at the end of January, one former Sun worker has taken the time to reflect a bit on the extravagant compensation and golden parachutes that the former executives at Sun are receiving for failing at their jobs. "I think it's fair to say that, for all the miscues that eventually led to its demise, the company created many products and technologies of value along the way, enough so that Oracle thought it was worth it to acquire them and try to keep them going. However, I think that it's equally fair to conclude that, after years of running losses, including about $2 billion in fiscal 2009, so that a buyout was necessary to avoid looming bankruptcy, Sun's executives did nothing to deserve lavish rewards, by any conceivable meaning of the word 'deserve.' But what actually happened is by now a familiar story. [...] And here's a prediction that I feel quite certain of: if, against expectations and my hopes, Ellison drops the ball and things start going south for Oracle, it's the employees who will suffer for it, and he'll be doing just fine."

Restructured Ruby on Rails 3.0 Hits Beta 197

Curlsman informs us that the first beta of Ruby on Rails 3.0 has been released (release notes here). Rails founder David Heinemeier Hansson blogged that RoR 3.0 "feels lighter, more agile, and easier to understand." This release is the first the Merb team has participated in. Merb is a model-view-controller framework written in Ruby, and they joined the RoR development effort over a year ago. Reader Curlsman asks, "So, is version 3 of RoR going to be a big deal, more of the same (good or bad), or just churning technology?"

An Interview With F# Creator Don Syme 267

OCatenac passes along an interview with Don Syme, chief designer of F#, which is Microsoft Research's offering for functional programming on the .Net platform. Like Scala, which we discussed last fall, F# aims at being an optimal blend of functional and object-oriented languages. "[Q] What is the best program you've seen written in F#? [A] I've mentioned the samples from F# for Scientists, which are very compelling... For commercial impact then the uses of F# in the finance industry have been very convincing, but probably nothing beats the uses of F# to implement statistical machine learning algorithms as part of the Bing advertisement delivery machinery. ... We've recently really focused on ensuring that programming in F# is simple and intuitive. For example, I greatly enjoyed working with a high-school student who learned F#. After a few days she was accurately modifying a solar system simulator, despite the fact she'd never programmed before. You really learn a lot by watching a student at that stage."

Game Devs Migrating Toward iPhone, Away From Wii 143

A new report by Game Developer Research reveals that the number of developers working on games for the iPhone continues to rise, roughly doubling in number from last year. At the same time, the amount of work done on games for Nintendo's Wii dropped significantly: "Just over 70 percent of developers said they were developing at least one game for PC or Mac (including browser and social games), rising slightly from last year; 41 percent reported working on console games. Within that latter group, Xbox 360 was the most popular system with 69 percent of console developers targeting it, followed by 61 percent for PlayStation 3. While those console figures stayed within a few percent of last year's results, the change in Wii adoption was much more significant: reported developer support for the system dropped from 42 percent to 30 percent of console developers, supporting numerous publishers' claims of a recent softening of the Wii market."

Symbian Completes Transition To Open Source 189

Grond writes "Symbian, maker of the the world's most popular mobile operating system, has completed the transition to a completely open platform months ahead of schedule. While the kernel was opened up last year, the entire platform is now open source, primarily under the Eclipse Public License. A FAQ is available with more information about the platform opening." Adds an anonymous reader, linking to PC Magazine's story on the transition: "By putting Symbian fully in the public domain, the Symbian Foundation is pitting it against Google's Android. Symbian is well known across most of the world, but it's mostly a foreign curiosity in the US, AT&T is the only carrier that currently has a symbian phone in its lineup, the Nokia E71x."

Code Review of Doom For the iPhone 161

Developer Fabien Sanglard has written a code review for id Software's iPhone port of Doom. It's an interesting look into how the original 1993 game (which he also reviewed to understand its rendering process) was adapted to a modern platform. "Just like Wolfenstein 3D, Doom was rendering a screenframe pixel per pixel. The only way to do this on iPhone with an acceptable framerate would be to use CoreSurface/CoreSurface.h framework. But it is unfortunately restricted and using it would prevent distribution on the AppStore. The only solution is to use OpenGL, but this comes with a few challenges: Doom was faking 3D with a 2D map. OpenGL needs real 3D vertices. More than 3D vertices, OpenGL needs data to be sent as triangles (among other things because they are easy to rasterize). But Doom sectors were made of arbitrary forms. Doom 1993's perspective was also faked, it was actually closer to an orthogonal projection than a perspective projection. Doom was using VGA palette indexing to perform special effect (red for damage, silver for invulnerable...)."

Android and the Linux Kernel Community 354

An anonymous reader links to Greg Kroah-Hartman's explanation of a rift (hopefully mendable) in the development culture of Google's Linux-based Android OS and the Linux kernel itself. "As the Android kernel code is now gone from the Linux kernel, as of the 2.6.33 kernel release, I'm starting to get a lot of questions about what happened, and what to do next with regards to Android. So here's my opinion on the whole matter ..."

Sun's Project Darkstar Game Server Platform No More 82

sproketboy writes "Project Darkstar, an open source software platform from Sun labs that simplifies the development of horizontally scalable servers for online games, is being discontinued as of the Oracle acquisition. This project, mentioned a couple of years back on Slashdot, was a unique concept for building an application server specific to on-line gaming. Sadly they were so close at version 0.9.11 (which is still very stable). Hopefully the open source community can get involved and help continue work on this project."

Eight PHP IDEs Compared 206

snydeq writes "InfoWorld's Rick Grehen provides an in-depth comparative review of eight PHP IDEs: ActiveState's Komodo IDE, CodeLobster PHP Edition, Eclipse PHP Development Tools (PDT), MPSoftware's phpDesigner, NetBeans IDE for PHP, NuSphere's PhpED, WaterProof's PHPEdit, and Zend Studio. 'All of these PHP toolkits offer strong support for the other languages and environments (HTML, CSS, JavaScript, SQL database) that a PHP developer encounters. The key differences we discovered were in the tools they provide (HTML inspector, SQL management system) for various tasks, the quality of their documentation, and general ease-of-use,' Grehen writes.'"

Facebook's HipHop Also a PHP Webserver 304

darthcamaro writes "As expected, Facebook today announced a new runtime for PHP, called HipHop. What wasn't expected were a few key revelations disclosed today by Facebook developer David Recordan. As it turns out, Facebook has been running HipHop for months and it now powers 90 percent of their servers — it's not a skunkworks project; it's a Live production technology. It's also not just a runtime, it's also a new webserver. 'In general, Apache is a great Web server, but when we were looking at how we get the next half percent or percent of performance, we didn't need all the features that Apache offers," Recordon said. He added, however, that he hopes an open source project will one day emerge around making HipHop work with Apache Web servers.'"

Facebook Rewrites PHP Runtime For Speed 295

VonGuard writes "Facebook has gotten fed up with the speed of PHP. The company has been working on a skunkworks project to rewrite the PHP runtime, and on Tuesday of this week, they will be announcing the availability of their new PHP runtime as an open source project. The rumor around this began last week when the Facebook team invited some of the core PHP contributors to their campus to discuss some new open source project. I've written up everything I know about this story on the SD Times Blog."

Unofficial Qt Environment (and Sudoku) For the Kindle 36

An anonymous reader writes "I've just posted packages for installing a Qt-based platform on the Kindle 2 and DX devices, and a Sudoku game to go along with it. The Qt-based platform includes plugins I wrote for the e-ink display, the keyboard, and the five-way joystick thing — so it's a fully interactive and usable environment now. Soon I'll be adding a sample app with source code to go along with it."

Novell Bringing .Net Developers To Apple iPad 315

GMGruman writes "Paul Krill reports that Apple's new iPad could be easier to write apps for, thanks to Novell's MonoTouch development platform, which helps .Net developers create code for the iPad and fully comply with Apple's licensing requirements — without having to use Apple's preferred Objective-C. This news falls on the footsteps of news that Citrix will release an iPad app that lets users run Windows sessions on the iPad. These two developments bolster an argument that the iPad could eventually displace the netbook."

x86 Assembler JWASM Hits Stable Release 209

Odoital writes "January 2010 is an exciting month for x86 assembly language developers. Software developer Andreas Grech, better known to the x86 assembly language community and the rest of the world by his handle "japheth," has released another version of JWASM — a steadily growing fork of the Open Watcom (WASM) assembler. The main benefit of JWASM, arguably, is the nearly full support of Microsoft's Macro Assembler (MASM) syntax. As those in the assembly language community may already know, Microsoft's desire to continually support the development of MASM has been dwindling over the years — if only measurable by a decreasing lack of interest, updates and bug fixes — and thus the future of MASM remains uncertain. While Intel-style syntax x86 assemblers such as NASM have been around for a while, JWASM opens up a new possibility to those familiar with MASM-style syntax to develop in the domains (i.e. other than Windows) in which assemblers such as NASM currently thrive. JWASM is a welcomed tool that supplements the entire x86 assembly language community and will hopefully, in time, generate new low-level interests and solutions."

With New SDK, VoIP Over 3G Apps Now Working On iPhone 171

silverpig writes "Yesterday marked the announcement of the Apple iPad device, and with it came a new version of the SDK. In this new version, Apple has lifted the VoIP over 3G restrictions that limited VoIP traffic to wifi only. This morning, Fring announced that its iPhone app is 3G-capable starting immediately. No update is needed as apparently the app had 3G capability all along, but a server-side block prevented its use. Furthermore, apparently a 3G-capable version of Skype has been ready for some time now, and has been waiting for this restriction to be lifted."
