SpamShield: A Perl-Based Spam Filter for sendmail (O'Reilly)

Glenn Graham introduces SpamShield on O'Reilly. "The science of spam (if you can call it that) has taught us one thing: spam leaves a definite "calling card" in the system logs. This calling card is generally repetitive enough that the process of tracking spam may be automated. Based on this theory, a brilliant programmer by the name of Kai Schlichting wrote a Perl-based program called SpamShield."

Server clinic: PDF for the server (IBM developerWorks)

Cameron Laird writes about server-side PDF file generation on IBM's developerWorks. "PDF is the recognized standard for several categories of top-quality displayable output. While most programmers regard it as a "desktop" technology, a format that a content specialist chooses through a SaveAs operation, you can make your document management processes more powerful through server-side automation of PDF creation. This month, Cameron introduces the ReportLab library for PDF management and programming."

In this article, I'll dig a bit deeper and discuss how JSTL can help you with internationalization and database access. The bulk of the article does not require any Java programming knowledge, but the sections that deal with how servlets and other Java classes interact with the JSTL actions do."

Retire your debugger, log smartly with Log::Log4perl! (O'Reilly)

Michael Schilli explains the Log::Log4perl Perl logging package on O'Reilly. "You've rolled out an application and it produces mysterious, sporadic errors? That's pretty common, even if fairly well-tested applications are exposed to real-world data. How can you track down when and where exactly your problem occurs? What kind of user data is it caused by? A debugger won't help you there. And you don't want to keep track of only bad cases. It's helpful to log all types of meaningful incidents while your system is running in production, in order to extract statistical data from your logs later."

XML

What Are Topic Maps? (O'Reilly)

Lars Marius Garshol introduces topic maps for organizing XML encoded information. "When XML is introduced into an organization it is usually used for one of two purposes: either to structure the organization's documents or to make that organization's applications talk to other applications. These are both useful ways of using XML, but they will not help anyone find the information they are looking for. What changes with the introduction of XML is that the document processes become more controllable and can be automated to a greater degree than before, while applications can now communicate internally and externally. But the big picture, something that collects the key concepts in the organization's information and ties it all together, is nowhere to be found. This is where topic maps come in."

Text in SVG is real text; to write Hello World! in an SVG document, you have to write something like Hello World!. This comes in handy with regard to accessibility as it means that SVG text is searchable and indexable."

Identity Crisis (O'Reilly)

Kendall Grant Clark studies the W3C's "Architectural Principles of the World Wide Web" document on O'Reilly. "In the APW's view, the Web is a "universe of resources". So far, so good. But what is a resource? The APW adopts the definition of resource from RFC 2396, a definition which has always made me uneasy, though probably because I'm still more inclined to think of these things like a philosopher than like a programmer or software system architect."
