Precision writes to inform us about the Swiss firm Myriad, which claims a 3x boost in Android app performance and longer battery life with a new virtual machine. Myriad says that its technology is 100% compatible with existing Android apps. "The tool is a replacement for the Dalvik virtual machine, which ships as part of the Android platform, and retains full compatibility with existing software. Dalvik Turbo also supports a range of processors including those based on ARM, Intel Atom, and MIPS Architectures."

itwbennett writes "It can take a fairly stable team of programmers as long as six months to get to a point where they're estimating programming time fairly close to actuals, says Suvro Upadhyaya, a Senior Software Engineer at Oracle. Accurately estimating programming time is a process of defining limitations, he says. The programmers' experience, domain knowledge, and speed vs. quality all come into play, and it is highly dependent upon the culture of the team/organization. Upadhyaya uses Scrum to estimate programming time. How do you do it?"

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.'"

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."

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).

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."

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?"

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."

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."

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."
