Bogofilter 0.2 released

Eric Raymond has released version 0.2 of bogofilter, a new spam filtering package. "Bogofilter is a Bayesian spam filter. In its normal mode of operation, it takes an email message or other text on standard input, does a statistical check against lists of "good" and "bad" words, and returns a status code indicating whether or not the message is spam. Bogofilter is designed with fast algorithms (including the Judy fast-associative-array technique), coded directly in C, and tuned for speed, so it can be used for production by sites that process a lot of mail."

Get started with Castor JDO (IBM developerWorks)

Bruce Snyder shows how to do object-relational data binding with the Castor JDO (Java Data Objects) on IBM's developerWorks. "A growing number of enterprise projects today call for a reliable method of binding Java objects to relational data -- and doing so across a multitude of relational databases. Unfortunately (as many of us have learned the hard way) in-house solutions are painful to build and even harder to maintain and grow over the long term. In this article, Bruce Snyder introduces you to the basics of working with Castor JDO, an open source data-binding framework that just happens to be based on 100 percent pure Java technology."

John Coggeshall illustrates PHP objects on O'Reilly. "In my last article, I wrapped up my discussion of using objects in PHP.

For those of you without programming experience in C, don't worry! I'll be covering everything you'll need to know today."

The Absent Yet Present Link (O'Reilly)

Kendall Grant Clark writes about some issues with the W3C draft specifications for XHTML 2.0 on O'Reilly. "As is often the case, however, reaction to a new W3C specification, even a very early draft, exposed a venerable, enduring fault line in the XML world, namely, the split between XML users and XML core developers. In this case, we'll let the former be represented by the weblogging community, the latter by the XML-DEV list. Of course, this division is mostly a fiction, a little heuristic I'm using to make a larger point, but it's not entirely divorced from reality."

Mastering Linux debugging techniques (IBM developerWorks)

Here's a developerWorks article that explains Linux debugging tools and techniques in various scenarios. "When your program contains a bug, it is likely that somewhere in the code, a condition that you believe to be true is actually false. Finding your bug is a process of confirming what you believe is true until you find something that is false." (Thanks to Debra Suzuki)
