"When old programmers like me (I'm 41) get together we talk about the applications from the old days. What happens to these beauties?" Read the editorial at ZDNews.

There has been a growing movement in the computer industry as of late towards exploration of more database-like filesystem paradigms - the reason being that today's filesystems are primitive, scattered, and cannot efficiently manage the immense amount of information that computer users have to work with on a regular basis every day.

"Visual Studio .NET 2003 just came out as a "final beta." I’ve been developing on it for a while now, and I want to point out some of the signature features and tools in this product.2 Read the article at 3Leaf.com.

The GCC Project has just updated its front page with the addition of two significant announcements: support for precompiled headers (PCH) and a new C++ parser that has brought g++ near the top of the food chain in conformance and led to over 100 bugs being closed.

"XP works best for medium-sized teams where a product can be delivered in stages, and where there's freedom to experiment with some of the more controversial techniques," author Ron Jeffries said.

This article looks at two behaviors of the scheduler. The first behavior is the reaction to adding more choices to the scheduler's switching decision. The second demonstrates fairness by performing a uniform workload in multiple threads. Source code is provided so you can experiment. Last month's column looked at bare context switch times by using the best primitives on both Windows and Linux. According to those results, context switch time under Windows takes only half as long as under Linux.

News.com has published a 2002 in Review piece on the open source segment of the technology industry. Open source had a very good year in 2002, even as (or perhaps because) the rest of the industry suffered financially. Linux made strides in adoption at large companies and saw some major improvements in power and usability, Open Office became usable, Microsoft started to get scared, and Sun finally succumbed to "if you can't beat 'em, join 'em." Most of all, even though scores of small companies went out of business as venture funding from the last millennium finally ran out, Open Source software is still around, and flourishing.

"In my previous article, I introduced the C# programming language and explained how it works in the context of the Mono environment, an open-source implementation of Microsoft's .NET framework. I will now go on to some details on the data types supported by the C# programming language." Read the second article at LinuxGazette. Another development article ("Writing Portable Code") is here.
