"Homesteading the Noosphere" problems on Zebra

Users of the GNU Zebra TCP/IP routing software have had some problems getting response from the code's author. A co-project has been formed to deal with the issue. "This bring an interesting twist to ESR 'Homesteading the Noosphere': What if the maintainer once did a great job, then is not up to par with what its community expects, but instead of giving away control or refusing to do so, just remains silent on the subject and acts as if the problem does not exist?"

Building a Vector Space Search Engine in Perl (O'Reilly)

Maciej Ceglowski writes about vector-space search engines on O'Reilly. "As a Perl programmer, sooner or later you'll get an opportunity to build a search engine. Like many programming tasks - parsing a date, validating an e-mail address, writing to a temporary file - this turns out to be easy to do, but hard to get right. Most people try end up with some kind of reverse index, a data structure that associates words with lists of documents. Onto this, they graft a scheme for ranking the results by relevance."

Metaclass programming in Python (IBM developerWorks)

David Mertz, and Michele Simionato explain metaclass programming concepts in Python. "Most readers are already familiar with the concepts of object-oriented programming: inheritance, encapsulation, polymorphism. But the creation of objects of a given class, with certain parents, is usually thought of as a "just so" operation. It turns out that a number of new programming constructs become either easier, or possible at all, when you can customize the process of object creation. Metaclasses enable certain types of "aspect-oriented programming," for example, you can enhance classes with features like tracing capabilities, object persistence, exception logging, and more."

Design XML schemas using UML (IBM developerWorks)

Ayesha Malik writes about the business applications of UML. "Unified Modeling Language (UML) is an industry standard that is used in modeling business concepts when building software systems in an object-oriented manner. Recently, XML has gained ground in becoming a key enabler of these systems in terms of transport of information and commands. XML schemas, which are used to define and constrain the nature of XML exchanged, have consequently come into the limelight. This article discusses the use of UML in designing XML schemas and gives a hands-on approach for using the UML framework to create your XML vocabularies."

The Pace of Innovation (O'Reilly)

Kendall Grant Clark discusses XML language development on O'Reilly. "In last week's column I suggested, only half-jokingly, that one motivation for new XML developments was to give techie journalists like me something new to write about. In making this silly claim, I was primarily reacting to what is widely seen as a kind of monotonous redundancy on the XML-DEV mailing list, an important part of the XML development community. If XML-DEV is any indication, the development community believes there are innovations remaining to be achieved with XML, but since the pace of innovation has slowed, it returns repeatedly to core, essentially, contested issues seems to relieve some of the psychological burden of expecting new things and not getting them."

XP and XML (O'Reilly)

Eric van der Vlist writes about extreme programming (XP) and XML on O'Reilly. ... "the more I think about it, the more I am convinced that both XP and XML could benefit from working more closely together. And there may even be some hope for remote pair programming. I can't pretend to have real experience with XP but only with some of its practices, which I have been able to follow despite my remoteness. Therefore, most of this article is theoretical, but I hope that these ideas will still be useful."
