sytelus writes "Many has played with the idea of packaging calendar information in to the RSS feed. Almost every other website owned by some kind of group or organization has an event calendar so the thought of aggregating those events in to your calendar is pretty appealing. Even more appealing is the thought that people might start tagging their weekend plans and schedules in their RSS feeds. This essay , written after digging through dozens of W3C specs and half a dozen of implementations, reviews the current state of affair."

Bob Bobbinson asks: "I'm currently looking to convert my workplace's CVS repository over to Subversion. The main issue I'm having at the moment before I can commence a roll-out is how we are currently using tags, and sticky tags. The project is a website and we have two tags which are used to put changes from the main trunk live (internally, and externally). All development is committed to the main branch, and when we want a change to go live we move the two 'live' tags to that current version. The live servers are both sticky tagged to these tags, so when we run an update on these servers they will only update to the version that the 'live' tags refer to. Currently I haven't found a satisfactory way to replicate this in Subversion, as moving tags, and updating on separate servers seems to be quite kludgy i.e. need to remove current tagged version from tag, then copy from the main branch over to the tag, then update this on the live server. So I'm trying to look for an alternative way to implement this staggered releasing of code live, and maintaining the ability to see what versions of files constitute what is live. Any ideas?"

CowboyRobot writes "Relational databases were developed in the 1970s as a way of improving the efficiency of complex systems. But modern warehousing of data results in terabytes of information that needs to be organized, and the growing prevalence of mobile devices points to the increasing need for intelligent caching on the local hardware. According to the ACM, the future of database architecture must include more modularity and configuration. Although no concrete solutions are included, the article is a good overview of the problems with modern data systems."

morcheeba writes "According to an EETimes article, IBM is planning on releasing the full specifications and software libraries for the powerful processor that will be in the Playstation 3. The goal is to stimulate open-source development for other applications of the chip. The article doesn't mention if there will be some affordable development systems for all these programmers -- I'm hoping for a ps3 devkit." From the article: "IBM is eager to find other opportunities for Cell, but it's going to take a lot of software work...Going to the open-source community makes sense, because they could attract a lot of pretty smart programmers who could spin out software and applications for Cell."

samuel4242 writes "Javascript may have been with us since the beginning of the browser, but it's going through a renaissance as companies like Google create Javascript-enabled tools like Google Maps . There's even a nice, newly coined acronym , AJAX for "Asynchronous Javascript and XML". A nice survey article from Infoworld interviews Javascript creator, Brendan Eich, who says that this is what he and Marc Andreessen planned from the beginning. Perhaps AJAX will finally deliver what Java promised. Perhaps it will really provide a solid way to distribute software seamlessly."

This article compares the optimization options for both Linux on POWER C/C++ compilers: GCC and IBM XL C/C++. This paper also reviews tactics, such as Interprocedural Analysis, Profile Directed Feedback, and High Order Transformations, which are used by one or both of the compilers to extract higher performance from the Power architecture."

Jacco de Leeuw writes "Windows Mobile developers have enjoyed free development tools like the eMbedded Visual Tools and that in turn has helped popularize Windows Mobile devices and a number of free or cheap applications. But now the SDK for the upcoming Windows Mobile 5.0 has a number of 'technical (not political) dependencies' on Visual Studio 2005, which starts at $299. Is it time for an open source Windows Mobile toolchain?"

Here's some interviews with the people behind the release about the new features, including information about which companies are complying with requests for documentation and permission to freely distribute required firmware, and which are not. Ralink Tech and Realtek 'GOOD,'Intel 'BAD.' The next time I build/buy a wireless product, I'll want Realtek or Ralink Tech inside -- because getting software to work with it will be easier. Ralink Tech and Realtek are Taiwanese, by the way."

thesamet writes "The Python Challenge is a set of riddles that require a little bit of Python programming to be solved. The purpose of the riddles is to provide an entertaining way to explore the Python programming language. The challenge was started late in April this year and it is starting to gain popularity in the Python community. What people love most about the challenge is that it makes them poke in Python's module library and discover new things. It truly demonstrates the great power of Python's included 'batteries.' The riddles are designed to be solvable by Python beginners, but yet are challenging even to experienced Python programmers. The first few riddles are very easy, but it gradually becomes more and more challenging. Many people reported that playing the challenge is highly addictive and it is great fun. The site also features discussion forums where users can ask for hints. Additionally, after solving a riddle, its solution is available in a wiki form."

njcoder writes "Netbeans 4.1 was released a few days ago. Though it is only a short time since 4.0 was released and only a minor version number increase, the new Netbeans 4.1 contains a number of significant enhancements. New features include enhanced support for J2ME (mobile) projects, a new Navigator component, enhancements to the Ant based project system, ability to define multiple source roots, enhanced support for J2EE applications including EJB support for creating Session, Entity and Message Driven Beans, bundled J2EE application server, bundled Tomcat server upgraded to the 5.5 series, Web Services support, Eclipse project import tool, and more. The days of a slow and ugly Netbeans seem to be over. Using the new Metal look and feel in Java 5 brightens things up a bit as well. More information can be found in the release info and go here to download the new version. Java boutique has a review, with screenshots, of the new released titled IDE Wars: Has NetBeans 4.1 Eclipsed Eclipse?."

Anil Kandangath writes "Last year, Computer Associates open sourced their Ingres DMBS and they also announced a $1mn bounty for open source conversion toolkits from other databases to Ingres. Well, the toolkits are up on SourceForge and the bounty has been won by three teams, two from India and one from New York. More details and links to the projects on the CA news page. This is one of the greatest bounties for open source software and will hopefully serve as a model for other companies taking this path of cheaper development and better code."

Flaming Foobar writes "Tom Eastep has announced that he is quitting all development and support of my favorite iptables front-end, Shorewall. In his e-mail to the Shorewall Users mailing list he states that 'just cannot deal with the support and documentation frustration any more -- support, the documentation and the web site consume an order of magnitude more of my time than does Shorewall development.' I can't help but wonder if this could happen to more OSS projects in the future - will people get tired of donating huge chunks of their life to free software?"

It now has threading support, interfaces, widestring and better Delphi support among many other new features. OSNews posted an article introducing the updated GPL compiler." petermgreen adds a list of some of the major changes since the last stable release: "Much better support for Delphi language features (especailly method pointers); more supported CPUs (AMD64, SPARC, PPC (32 bit), ARM) and platforms (Mac OS classic, Mac OS X, MorphOS, Novell Netware); a new and better structured Unix RTL Threading support; and a large number of internal changes including rewriting large parts of the compiler to make it more maintainable and easier to port to new architectures," and notes that "Visual parts of Delphi are being handled by a seperate project known as lazarus, which has not yet reached 1.0 but should do so fairly soon."
