jamie writes "chromatic has a great post today on the conflict between OS distributions and CPAN's installations of perl modules, along with some suggestions for how to start resolving this maddening problem: '[Though Debian has] made plenty of CPAN distributions available as .debs, I have to configure my CPAN client myself, and it does not work with the system package manager. There's no reason it couldn't. Imagine that the system Perl 5 included in the default package... had a CPAN client configured appropriately. It has selected an appropriate mirror (or uses the redirector). It knows about installation paths. It understands how to use LWP...' The idea of providing guidelines to distros for how to safely package modules is a great one. Could modules request (a modified?) test suite be run after distro-installation? Could Module::Build help module authors and distro maintainers establish the rules somehow?"

theodp writes "John D. Cook takes a stab at explaining why programmers are not paid in proportion to their productivity. The basic problem, Cook explains, is that extreme programmer productivity may not be obvious. A salesman who sells 10x as much as his peers will be noticed, and compensated accordingly. And if a bricklayer were 10x more productive than his peers, this would be obvious too (it doesn't happen). But the best programmers do not write 10x as many lines of code; nor do they work 10x as many hours. Programmers are most effective when they avoid writing code. An über-programmer, Cook explains, is likely to be someone who stares quietly into space and then says 'Hmm. I think I've seen something like this before.'"

Gregory Diamos writes "An open source project, Ocelot, has recently released a just-in-time compiler for CUDA, allowing the same programs to be run on NVIDIA GPUs or x86 CPUs and providing an alternative to OpenCL. A description of the compiler was recently posted on the NVIDIA forums. The compiler works by translating GPU instructions to LLVM and then generating native code for any LLVM target. It has been validated against over 100 CUDA applications. All of the code is available under the New BSD license."

jammag writes "A veteran developer looks back — in irritation — at those times he had to work late and his unskilled manager stayed too, just to look over his shoulder and add worry and fret to the process. Now, that same developer is a manager himself — and recently stayed late to ride herd over late-working developers. 'And guess what? Yep, I hadn't coded in years and never in the language he had to work with.' Yet now he understood: his own butt was on the line, so he was staying put. Still, does it really help developers to have management hovering on a late evening, even if the boss handles pizza delivery?"

introspekt.i writes "Palm is building upon the Mozilla Bespin project to deliver an IDE for the Palm Pre entirely in the web browser. Apps can be developed on the server and then downloaded and deployed locally. It is an interesting tool, especially given that WebOS is so web-centric. This tool comes as a supplement to the existing development tools for Eclipse and the command line released by Palm earlier this year. The project is open to anyone who registers as a Palm developer, which is free to do."

Kensai7 writes "Recently, Facebook provided us with some information on their server park. They use about 30,000 servers, and not surprisingly, most of them are running PHP code to generate pages full of social info for their users. As they only say that 'the bulk' is running PHP, let's assume this to be 25,000 of the 30,000. If C++ would have been used instead of PHP, then 22,500 servers could be powered down (assuming a conservative ratio of 10 for the efficiency of C++ versus PHP code), or a reduction of 49,000 tons of CO2 per year. Of course, it is a bit unfair to isolate Facebook here. Their servers are only a tiny fraction of computers deployed world-wide that are interpreting PHP code."

joabj writes "While MySQL is the subject of much high-profile wrangling between the EU and Oracle (and the MySQL creator himself), the MySQL developers have been quietly moving the widely-used database software forward. The new beta version of MySQL, the first publicly available, features such improvements as near-asynchronous replication and more options for partitioning. A new release model has been enacted as well, bequeathing this version the title of 'MySQL Server 5.5.0-m2.' Downloads here."

cyclocommuter writes with this snippet from The Register's assessment of whether Microsoft's .NET framework has been a success: "If the goal of .NET was to see off Java, it was at least partially successful. Java did not die, but enterprise Java became mired in complexity, making .NET an easy sell as a more productive alternative. C# has steadily grown in popularity, and is now the first choice for most Windows development. ASP.NET has been a popular business web framework. The common language runtime has proved robust and flexible. ... Job trend figures here show steadily increasing demand for C#, which is now mentioned in around 32 per cent of UK IT programming vacancies, ahead of Java at 26 per cent."

JerBear0 writes "I work as the sole IT employee at a company of about 50 people. I handle programming, support, pretty much anything that is IT related, or even that plugs in. As seems to be true with many small companies, the priorities seem to shift quite frequently. As a result, I've always got multiple programming (both new systems and improvements/changes to existing systems), integration, research, maintenance tasks/projects on my To Do list, in varying stages of completion. At any given time, I need to be able to jump back to one of these items and pick up where I left off. I am currently using Outlook Tasks, and then end up referencing my notebook and email for those dates to figure out exactly where I left off. It works, but not well. If it's been a while, I'll end up losing an hour or two just tracking everything down. I looked at using MS Project / OpenProj, but they want an individual file for each project, and I want at least the project/task list all on one screen. Essentially what I'd want would be a Task List on steroids, allowing for hierarchical subtasks, attachments, and prioritization. Ideally it would be a desktop app, but a locally-hostable web app would be okay. In some of these projects I may want to include proprietary information, which I really don't want floating out in the cloud outside of my control. I know I'm not alone in this problem, so what do you guys (gals) use to address this?"

Luke has no name writes "Yesterday we discussed MySQL founder Monty Widenius's objections to the acquisition of MySQL by Oracle. Today, Oracle released a statement to address some of these issues. Among their commitments, Oracle says they intend to continue releasing MySQL under the GPL, allow vendors to produce 'any-license' third-party engines, maintain the Reference Manual, invest millions into the product, and create a 'customer advisory board.' The pledges are still not enough for some, however."

blackbearnh writes "As previously reported on Slashdot, PayPal recently released a series of new APIs that allow developers to embed PayPal into their web sites and applications without requiring the user to go to the PayPal web site to complete the transaction. To encourage developers to use these new APIs, PayPal is offering two prizes totaling $150,000 for interesting new applications. The entry deadline to register ideas is December 16th, and O'Reilly has an interview with the director of the PayPal Developer Network that covers the details of the contest. In it, Naveed Anwar talks about why PayPal is throwing money at developers. 'When Facebook opened up their platform, it allowed people to work in that particular environment, in the Facebook environment. When the iPhone opened up their platform, they allowed people to work in their environment which was build the applications on the iPhone. When PayPal was looking at opening up its platform, we are not limited by one particular area. We go into the enterprises. We go into social networking. We go into all the places where payment as a solution is needed. And if we can actually reduce that barrier of entry — because at the end of the day, when anyone is building out a business and anyone is building out an application, they're looking at ways of monetizing it.'"

swsuehr writes "The Book of Xen: A Practical Guide for the System Administrator provides an excellent resource for learning about Xen virtualization. I frequently need to create test environments for examples that appear in various books and magazine articles (in the interest of full disclosure, I've never written for the publisher of this book). In the days before virtualization that meant finding and piecing together hardware. Like many readers, I've been using virtualization in one form or another for several years, including Xen. This book would've saved hours searching around the web looking for tidbits of information and sifting through what works and doesn't work in setting up Xen environments. The authors have done the sifting for me within the ~250 pages of the book. But far beyond, the authors also convey their experience with Xen using walkthroughs, tips, and recommendations for Xen in the real world." Read on for the rest of Steve's review.

jamie sends in a blog post from MySQL co-founder Monty Widenius calling for help to "save MySQL from Oracle's clutches." While the US DoJ approved Oracle's purchase of Sun back in August, the European Commission has been less forthcoming. Widenius points out that Oracle has been using their customers to put pressure on the EC, and he questions Oracle's commitment to MySQL, saying their vague promises aren't good enough. He writes: "Oracle has NOT promised (as far as I know and certainly not in a legally binding manner): To keep (all of) MySQL under an open source license; Not to add closed source parts, modules or required tools; To not raise MySQL license or MySQL support prices; To release new MySQL versions in a regular and timely manner; To continue with dual licensing and always provide affordable commercial licenses to MySQL to those who needs them (to storage vendors and application vendors) or provide MySQL under a more permissive license; To develop MySQL as an Open Source project; To actively work with the community; Apply submitted patches in a timely manner; To not discriminate patches that make MySQL compete more with Oracle's other products; To ensure that MySQL is improved also in manners that make it compete even more with Oracle's main offering."

BubbaDoom writes "In our cubicle-ville, we have programmers intermixed with accounting, customer support and marketing. As programmers, it is our habit to put on our headphones and listen to our portable music players to drown out all of the noise from everyone else. The boss recently sent an email just to the programmers demanding that we do not use our music players at work because he thinks it distracts us from our jobs and causes us to make mistakes. Of course, we've explained to him that prattle from the other people is much, much more distracting, but he insists his policy is the right one. What is the Slashdot community's experience with music at work for programmers?"

angry tapir writes "Microsoft may begin collecting royalties again for licensing some protocols because clear technical documentation is now available, according to the US Department of Justice. The change comes after the DOJ issued its latest joint status report regarding its 2002 antitrust settlement with Microsoft. The settlement required Microsoft to make available technical documentation that would allow other vendors to make products that are interoperable with Windows."

systembug writes "After 10 years of waiting and some infighting, ECMAScript version 5 is finally out, approved by 19 of the 21 members of the ECMA Technical Committee 39. JSON is in; Intel and IBM dissented. IBM is obviously in disagreement with the decision against IEEE 754r, a floating point format for correct, but slow representation of decimal numbers, despite pleas by Yahoo's Douglas Crockford." (About 754r, Crockford says "It was rejected by ES4 and by ES3.1 — it was one of the few things that we could agree on. We all agreed that the IBM proposal should not go in.")

An anonymous reader writes "Larry Wall wasn't joking when he said that Perl 6 would be ready by Christmas. Perhaps not this Christmas, but that hasn't stopped a group of people (including head Rakudo developers Patrick Michaud and Jonathan Worthington) from putting together an Advent Calendar, featuring one cool Perl 6 feature every day until Christmas. Topics currently covered include how to get and build Rakudo (the most actively developed and progressed implementation of Perl 6) and the new Metaoperators. For those wondering when Perl 6 will be finished: Rakudo will be having its official 'production release' (dubbed Rakudo Star) April 2010."

markmcb writes "A NASA engineer recently wrote about his disappointment that despite having well-documented coding practices, 'clever' solutions still made the code he has to maintain hard to follow. This got me thinking about the overhead spent at my own company regarding our code. We too have best practices that are documented, but most seem to focus on the basics, e.g., comments, modularity, etc. While those things are good, they don't directly ensure that quality, maintainable code is written. As the author points out, an elegant one-liner coupled with a comment from a few revisions ago makes for a good headache. I'm curious what experience others have had with this, and if you've seen manageable practices that ultimately offer a lot of value to the next programmer down the line who will have to maintain the code."

As a follow-up to Epic Games' release of a free version of the Unreal Engine last month, the company has now posted over 160 video tutorials which demonstrate the various uses of the Unreal Development Kit. Roughly 20 hours of footage were created by technical education company 3D Buzz, with topics ranging from user interface to game physics to cinematics.

An anonymous reader writes "Two weeks ago, The Daily WTF's Alex Papadimoulis announced Bad Code Offsets, a join venture between many big names in the software development community (including StackOverflow's Jeff Atwood and Jon Skeet and SourceGear's Eric Sink). The premise is that you can offset bad code by purchasing Bad Code Offsets (much in the same way a carbon-footprint is offset). The profits are donated to Free Software projects which work to eliminate bad code, such as the Apache Foundation and FreeBSD. The first cheques were sent out earlier today." Hopefully, they work better than carbon offsets, actually.
