Bill Venners writes "In this article, three programmers tell the story of how their frustration with JUnit's API led to the creation of Artima SuiteRunner, a free, open source test toolkit and JUnit runner. These programmers simply wanted to create a small add-on tool to JUnit, but found JUnit's design non-intuitive and API documention poor. After spending time reading through JUnit's source code and attempting to guess at the API contracts, they gave up and rewrote it."

Orome asks: "From the point of view of someone who wants to learn 3D Graphics programming, specifically for games, it is currently daunting to see the number of options available. Should I first learn OpenGL to understand the rudiments of 3D graphics programming, or should I try and understand the Direct3D API (which has more to offer but is less easier to understand)? With the DX9.0 SDK available, would it be advisable to jump to the next level and learn how to use the high level shading language? Since shading languages are supposed to be THE next thing in 3D programming would Cg be a better tool to learn since it is cross platform." OpenGL and DirectX are always options, but might there be something a little less daunting for those just starting out?

maverick2003 asks: "Just while I was thinking that client-side Java is well and truly dead, here comes along a project, a really large one to boot, that involves developing a 'rich Java based client'. While I'm sure that given the right resources and time-frame, this is certainly possible, I was wondering what kind of experiences the Java community has with developing large Java client side applications. Five years ago, Swing and Java client technology had light-years to go before matching up with native Windoze APIs. Getting Swing to do exactly what you wanted, was a guaranteed trip into pure hell itself, with all sorts of weird bugs and workarounds to deal with. The applications that I've developed since then uses VB/VC++ and will talk to a Java server. This has gotten much easier nowadays with SOAP libraries available for cross-platform stuff. Have things improved since then? If yes, by what degree?" What would you use as an example of a large-scale, real-world, high-quality client-side Java application?

BoneFlower asks: "Due to early registrations scooping up most of the good electives at my school, I'm stuck with learning COBOL(required CS class at my school) and Visual Basic.NET (only useful CS elective left) at the same time. The only tips I've gotten from IRC are 'drop one' and 'Focus on COBOL only enough to pass, and put most of your effort on Visual Basic'. I'd prefer to learn both well, do any of you have any suggestions on how to do this? What aspects of each could I use to enhance the other, and what apparent similarities should I keep in mind as dangerous traps? I also have some C++ knowledge, up to basic classes and memory management, so any of that that I could use in the current classes would be useful as well."

suzanne writes "The deadline cometh: if you have a hankering to participate in the 2003 O'Reilly Open Source Convention, get your proposal/s in by February 15. It's in Portland this year, and a little earlier than usual, July 7-11. (If you missed the fun last time, check out last year's coverage page, especially SuperSnail's photos of the event.)"

Joe Barr writes "The story of how BitKeeper has come to be Linus Torvalds' (and many other kernel hackers) tool of choice in maintaining the Linux development tree is worthy of a book. Here's the Cliff Note's version of McVoy's contribution to Linux kernel development, BitKeeper, and countless hours of flaming on the role of open source and proprietary software."

PHPee writes ""Learn the concepts and build the applications..." - PHP and MySQL Web Development is a well-written web developer's guide to using these open source products to create dynamic websites quickly and easily. This book covers everything you need to design, build and debug your own website from the ground up. Special attention is paid real-world issues, like database normalization and site security. Overall, a great reference for beginner and more advanced programmers alike." Read on for the rest of his review.

Bill Venners writes "In this interview, Python creator Guido van Rossum states: 'I'm not particularly worried by the fact that people say you can prototype more easily in Python, but eventually the Java version makes it easier to build a robust large system. You can prototype in Python. Once you've explored the space more, you can do the planning and design that the Java version requires. If you start writing in Java knowing as little as you did when you started writing the Python version, you'll waste way more time exploring than actually building the system you'll eventually build.'"

An anonymous reader writes "Oasis has announced the formation of the Lawful Intercept XML Technical Committee. The announcement refers to it as a "universal global framework for supporting rapid discovery and sharing of suspected criminal and terrorist evidence by law enforcement agencies." It's not really clear if this is supposed to aid in information exchange about suspicious activities/individuals, or 'intercepting' in the sense of eavesdropping, or what exactly."

hardcorejon writes "Am I the only person who didn't notice that on November 18th 2002, the Apache Ant Project had migrated out from under the Jakarta Project umbrella to become a top-level Apache project, joining the ranks of the Apache HTTP Server Project? Well, for those of us who use Ant on a regular basis, this is great news. Ant is an incredibly powerful tool, increasingly a standard build system for many new projects."

Sky Lemon writes "An interview with Jaron Lanier on Sun's Java site discusses 'phenotropic' development versus our existing set of software paradigms. According to Jaron, the 'real difference between the current idea of software, which is protocol adherence, and the idea [he is] discussing, pattern recognition, has to do with the kinds of errors we're creating' and if 'we don't find a different way of thinking about and creating software, we will not be writing programs bigger than about 10 million lines of code no matter how fast our processors become.'"

AShocka writes "The W3C XML Schema Working Group has released the first public Working Draft of Requirements for XML Schema 1.1. Schemas are technology for specifying and constraining the structure of XML documents. The draft adds functionality and clarifies the XML Schema Recommendation Part 1 and Part 2. The XML Schema Valid FAQ highlights development issues and resources using XML Schema. This article at webmasterbase.com addresses the XML DTDs Vs XML Schema issue. Also see the W3C Conversion Tool from DTD to XML Schema and other XML Schema/DTD Editors."

Todd AvErth writes "Judge Motz recently ordered Microsoft to distribute Sun's JVM with every Windows product. Salon decided to pipe up about it with an editorial musing about whether or not it's too late. Most of it isn't all that interesting, but some of the comments from Ximian developer, Miguel de Icaza point to the advantage of being able to compile from multiple languages. Anyone know of any projects to compile JVM bytecode from other languages?" Update: 01/23 16:00 GMT by M : Comments were disallowed when this story was originally posted; fixed now. My mistake (although KDE3's stupid mouseover-activates-form-elements user interface, now finally fixed in the latest versions, has to take some blame too).

gsbarnes writes "Two Stanford researchers (Dawson Engler and Yichen Xie) have written a paper (pdf) showing that seemingly harmless redundant code is frequently a sign of not so harmless errors. Examples of redundant code: assigning a variable to itself, or dead code (code that is never reached). Some of their examples are obvious errors, some of them subtle. All are taken from a version of the Linux kernel (presumably they have already reported the bugs they found). Two interesting lessons: Apparently harmless mistakes often indicate serious troubles, so run lint and pay attention to its output. Also, in addition to its obvious practical uses, Linux provides a huge open codebase useful for researchers investigating questions about software engineering."

Joshua Wright writes "I have written a white paper on detecting spoofed MAC addresses on wireless LAN's. This paper describes some of the techniques attackers utilize to disrupt wireless networks through MAC address spoofing, demonstrated with captured traffic that was generated by the AirJack, FakeAP and Wellenreiter tools. Utilizing the techniques I describe, it is possible to identify users who utilize spoofed MAC addresses on 802.11 networks to launch denial of service attacks, bypass access control mechanisms, or falsely advertise services to wireless clients."
