Stevecrox asks: "I'm in my final year of university and have a working knowledge of C/C++, Visual Basic, VHDL and a variety of Assembler languages, however chatting to a friend on his placement year I've been told that C# is what employers are really looking for. What book would you recommend to someone looking to learn C# with my experience?"

The accepted Google Summer of Code 2007 mentors list is now complete at the Summer of Code website — 131 projects could use your help. Student applications are open and the end date is March 24. Google has an application guide in the Summer of Code Announce discussion group that provides more information on the application process.

warm sushi writes "An academic at the British Computing Society asks, Is computer science dead? Citing falling student enrollments and improved technology, British academic Neil McBride claims that off-the-shelf solutions are removing much of the demand for high-level development skills: 'As commercial software products have matured, it no longer makes sense for organizations to develop software from scratch. Accounting packages, enterprise resource packages, customer relationship management systems are the order of the day: stable, well-proven and easily available.' Is that quote laughable? Or has the software development industry stabilized to an off-the-self commodity?"

CoolVibe writes "Two Subversion developers talk at Google about how to keep pests and malcontents out of your open source projects. From the abstract: 'Every open source project runs into people who are selfish, uncooperative, and disrespectful. These people can silently poison the atmosphere of a happy developer community. Come learn how to identify these people and peacefully de-fuse them before they derail your project. Told through a series of (often amusing) real-life anecdotes and experiences.'"

mikemuch writes "Imran Haque has developed a mashup of Google Earth with data from the U.S. Census Bureau, called gCensus. The app uses the XML format known as KML (Keyhole Markup Language), which can create shapes and colors on the maps displayed by GE. Haque had to build custom code libraries (which he's made available as open source) that could generate KML for the project. He also had to extract the relevant data from the highly counter-intuitive Census Bureau files and store them in a database that could handle geographic data. gCensus lets you do stuff like create colorful overlays on maps showing population ages, race, and family size distributions."

An anonymous reader writes "To debug the FreeBSD kernel core dump efficiently, it is best to set up a remote debugging session between a development machine and the target machine, and remotely debug the kernel using serial communication. This article shows you how you can debug as many kernel images as you want; it becomes transparent to users once debugging starts, and your system's performance is not affected at all."

cronie writes "Not long ago, SourceForge.net announced the shutdown of the Compile Farm — a collection of computers running a wide variety of OSes, available for compiling and testing open source projects. SF.net stated their resources 'are best used at this time in improving other parts' of the service. I consider this sad news for the OSS community, because portability is one of the strengths of OSS, and not many of us have access to such a variety of platforms to compile and test our software on. As a consequence, I expect many projects dropping support for some of the platforms they can't get access to. Are there any sound alternatives with at least some popular OS/hardware combinations? Any plans to create one? (Perhaps Google or IBM might come up with something?)"

Coryoth writes "Design by Contract, writing pre- and post-conditions on functions, seemed like straightforward common sense to me. Such conditions, in the form of executable code, not only provide more exacting API documentation, but also provide a test harness. Having easy to write unit tests, that are automatically integrated into the inheritance hierarchy in OO languages, 'just made sense'. However, despite being available (to varying degrees of completeness) for many languages other than Eiffel, including Java, C++, Perl, Python, Ruby, Ada, and even Haskell and Ocaml, the concept has never gained significant traction, particularly in comparison to unit testing frameworks (which DbC complements nicely), and hype like 'Extreme Programming'. So why did Design by Contract fail to take off?"

Eric^2 writes "Oracle announced on Tuesday that TopLink will now be open source and a full-fledged Eclipse project. TopLink is an object-persistence layer for Java that maps Java objects to a relational database."

Plasma Droid writes "NewScientistTech has a story about a 3D molecular search engine that is over 1,500 times faster than anything previously developed. The researchers, from Oxford University, developed a lightning-fast way to quickly match 3D shapes mathematically. This could not only speed up searches for new drugs, but lead to 3D search engines, for finding objects uploaded to platforms such as Google Earth, they say." The problem will be in jump-starting the supply of 3D data about molecules and everything else.

An anonymous reader asks: "I've worked for a single, very large technology company since graduating from college in '89. My degree is in Computer Science, and I've written everything from embedded machine code for big iron to applications with Smalltalk. I'm still in development, but since '99 my programming tasks have been replaced by project management, some customer-facing work (technical-ish presentations, demonstrations, training, and the like), helping our marketing people position my team's work, and other things that programmers generally don't like to do. Are you a former developer who went into sales? If so, what were your experiences like from a professional and personal perspective? What advice would you give to a developer considering a new career in sales?"

Actual Reality points us to an interview in BusinessWeek.com with the man most often cited as the inventor of the MP3 format — though Karlheinz Brandenburg credits many for the development, including in particular Suzanne Vega.

UnreasonableMan writes "Jeff Hawkins is best known for founding Palm Computing and Handspring, but for the last eighteen months he's been working on his third company, Numenta. In his 2005 book, On Intelligence, Hawkins laid out a theoretical framework describing how the neocortex processes sensory inputs and provides outputs back to the body. Numenta's goal is to build a software model of the human brain capable of face recognition, object identification, driving, and other tasks currently best undertaken by humans. For an overview see Hawkins' 2005 presentation at UC Berkeley. It includes a demonstration of an early version of the software that can recognize handwritten letters and distinguish between stick figure dogs and cats. White papers are available at Numenta's website. Numenta wisely decided to build a community of developers rather than trying to make everything proprietary. Yesterday they released the first version of their free development platform and the source code for their algorithms to anyone who wants to download it."

BlueVoodoo writes "Java 5 added a number of powerful language features: generics, enumerations, annotations, autoboxing, and the enhanced for loop. Even if you're stuck on JDK 1.4, you can still use generics. Use Java and theory to learn how."

In the wake of E3's breakup, developers and attendees going to the annual Game Developer's Conference this week are wondering out loud: is the event losing its focus? As GDC expands, what was once (even just a few years ago) a somewhat quiet and intimate affair is taking on the airs of the now-deceased videogame extravaganza. The key for the Conference this year, the first post-E3, is going to be to make sure that the community aspect of the event remains intact in the face of over 12,000 attendees. As conference director Jamil Moledina points out, "The main lesson from (the transition of E3) is that we have to stick to what we do best: providing learning and inspiration to independent developers." Here's hoping the coming week bears that out.

An anonymous reader writes "Writing local Web applications can be quick, easy, and efficient for solving specific Intranet problems. Learn why a Web browser is sometimes a better interface than a GUI application and why experienced Web developers find themselves struggling to learn a GUI toolkit, and descover that a simple CGI script would serve their needs perfectly well, if not better."

An anonymous reader writes "The previously announced Month of PHP Bugs started three days ago, and already lists 8 security vulnerabilities in PHP and PHP related software. From the site: 'This initiative is an effort to improve the security of PHP. However we will not concentrate on problems in the PHP language that might result in insecure PHP applications, but on security vulnerabilities in the PHP core. During March 2007 old and new security vulnerabilities in the Zend Engine, the PHP core and the PHP extensions will be disclosed on a day by day basis. We will also point out necessary changes in the current vulnerability management process used by the PHP Security Response Team.'"

An anonymous reader writes "In a three-part Dr. Dobbs podcast, AI pioneer and MIT professor Marvin Minsky examines the failures of AI research and lays out directions for future developments in the field. In part 1, 'It's 2001. Where's HAL?' he looks at the unfulfilled promises of artificial intelligence. In part 2 and in part 3 he offers hope that real progress is in the offing. With this talk from Minsky, Congressional testimony on the digital future from Tim Berners-Lee, life-extension evangelization from Ray Kurzweil, and Stephen Hawking planning to go into space, it seems like we may be on the verge of another AI or future-science bubble."

Several readers wrote in with news of the momentum gathering behind free access to government-funded research. A petition "to create a freely available virtual scientific library available to the entire globe" garnered more than 20,000 signatures, including several Nobel prize winners and 750 education, research, and cultural organizations from around the world. The European Commission responded by committing more than $100 million towards support for open access journals and for the building of infrastructure needed to house institutional repositories able to store the millions of academic articles written each year. In the article Michael Geist discusses the open access movement and its critics.

Corbet writes "LWN.net did some data mining through the kernel source repository and put together an analysis of where the patches came from. It turns out that most kernel code is contributed by people paid to do the work — but the list of companies sponsoring kernel development has a surprise or two." The article's conclusion: "The end result of all this is that a number of the widely-expressed opinions about kernel development turn out to be true. There really are thousands of developers — at least, almost 2,000 who put in at least one patch over the course of the last year. Linus Torvalds is directly responsible for a very small portion of the code which makes it into the kernel. Contemporary kernel development is spread out among a broad group of people, most of whom are paid for the work they do. Overall, the picture is of a broad-based and well-supported development community."
