Development projects
News and Editorials
Psyco, the Python Specializing Compiler The [14]Psyco project by Armin
Rico has the goal of speeding up Python execution times.
"The aim of the Psyco project is to show that it is possible to
execute Python code at speeds approaching that of fully compiled
languages. The current prototype operates on i386-compatible
processors. Preliminary results show potential speed-ups of a factor
10 to 100, which means that we can hope execution speeds closer to
fully optimized C than to traditional Python."
The [15]project overview notes that Psyco works by replacing the most
inner loop of the standard CPython implementation, which means that it
can be integrated into CPython. "The name Psyco, or Python
Specializing Compiler, comes from the fact that the emitted machine
code is specialized to specific values of the data, not only to the
pseudo-code (a.k.a. bytecode) to interpret." There is also a hint that
the Psyco code may be useful for speeding up other interpreted
languages, it was written with that in mind.
Some of the [16]compatibility issues include missing bytecodes, a
number of code assumptions, assumptions that object types won't
change, and no support for the Python debugger, among other things.
Psyco may not be useful for all of the Python code ever written, but
it could be very useful for speeding up certain types of code.
The Psyco code and documentation [17]are licensed under the GPL
license.
Directory Management Systems
Ganymede 1.0.8 released. Version 1.0.8 of the Ganymede network
directory management system [18]has been announced. This version

of data objects, improvements to the XML loader, and other bug fixes.
Embedded Systems

Embedded Linux Newsletter for November 15 is out, with the usual
collection of interesting stuff from the Embedded Linux community.
Mail Software
PerlMx 1.2.2 Released (milter.org). Milter.org [20]examines the latest
PerlMx mail filtering software. PerlMx version 1.2.2 is a maintenance
release with a number of bug fixes.
Network Management
OpenNMS update. After a bit of a break, the OpenNMS project has
[21]produced a new development update. They have released
OpenNMS 0.9.0, which brings a great many changes and improvements.
There is also, now, a commercial support offering available at
[22]OpenNMS.com.
Printing Systems
CUPS v1.1.12 released. A new version of the CUPS printing system
[23]has been released. "CUPS 1.1.12 adds support for Polish PPD files,
adds a missing directory definition to the cups-config script, and
fixes bugs in the CUPS-Add-Printer and CUPS-Move-Job operations."
LPRng 3.8.1 available. Version 3.8.1 of the LPRng printing system
[24]is available. The [25]CHANGES relating to version 3.8.1 include a
number of bug fixes.
Omni printer driver adds more printers. The [26]Omni printer driver
now supports 392 different printers, [27]the list of supported
printers just keeps growing.
Science
Parsing Protein Domains with Perl (O'Reilly). James Tisdall [28]talks
about Perl and Biology software on perl.com. " Biological data on
computers tends to be either in structured ASCII flat files--that is
to say, in plain-text files--or in relational databases. Both of these
data sources are easy to handle with Perl programs."
Web-site Development
ASPSeek v.1.2.6 released. A new version of the ASPSeek web search
engine [29]is available. This release [30]features a bunch of bug
fixes and some minor tweaks.
Create RSS channels from HTML news sites (O'Reilly). Chris Ball
discusses techniques for creating a [31]Remote Site Summary with Perl
on O'Reilly's perl.com site. "Even if you haven't heard of the RSS
acronym before, you're likely to have used RSS in the past. Whether
through the slashboxes at slashdot or our own news summary at
use.perl.org, the premise remains the same - RSS, or 'Remote Site
Summary' is a method used for providing an overview of the latest news
to appear on a site."
The latest news from the Zope Members. This week, the [32]Zope
Members' news looks at the following new releases: BlogFace 0.1a,
LDAPUserFolder 1.0, CMFLDAP 1.1, Parsed XML 1.2.1. Other Zope news is
also featured.

contributions from Peter Freese."

which is a collection of OCaml modules that provide application-level
Internet access.
Lisp

published a tutorial that aims to help mathematicians make use of
Common Lisp.
Perl
Birth of the POE Documentation Project (use Perl). The POE (Persistent
Object Environment) Documentation project [74]has been created. "The

Python
Python 2.2 beta 2. The second (and probably last) beta of Python 2.2
has been [76]released. There's a few small new features, but this
release is mostly dedicated to bug fixes, as one might expect.
This week's Python-URL. [77]Dr. Dobb's Python-URL for November 16 is
out, with the latest from the Python development community.
Python Projects (FreshMeat). Ryan Kulla [78]pushes Python in an
article on FreshMeat. "When I found what Python had to offer, I was
amazed. I could write big applications very quickly, and the source
code was always easy to read because of how Python is built. Best of
all, Python is so easy to learn that you can literally learn it in a
weekend just from reading the online tutorial."
Optik: a Python command line parser. Version 1.1 of [79]Optik has been
released."Optik is a powerful, flexible, extensible, easy-to-use
command-line parsing library for Python. Using Optik, you can add
intelligent, sophisticated handling of command-line options to your
scripts with very little overhead." Optik is licensed under the BSD
license.
Ruby
The Ruby Garden. This week, [80]the Ruby Garden looks at a new Ruby
parser from Markus Liedl.
Tcl/Tk
This week's Tcl-URL. Here's [81]Dr. Dobb's Tcl-URL for November 20
with the latest from the Tcl/Tk community.
XML
XML::LibXML - An XML::Parser Alternative. This week's featured Perl
tool for working with XML is XML::LibXML. Kip Hampton [82]takes a look
on O'Reilly's XML.com. "Expat and XML::Parser have proven themselves
to be quite capable, but they are not without limitations. Expat was
among the first XML parsers available and, as a result, its interfaces
reflect the expectations of users at the time it was written. Expat
and XML::Parser do not implement the Document Object Model, SAX, or
XPath language interfaces (things that most modern XML users take for
granted) because either the given interface did not exist or was still
being heavily evaluated and not considered 'standard' at the time it
was written."
XML::SAX::Expat Released (use Perl). Meanwhile, use Perl [83]looks at
XML::SAX::Expat. "XML::SAX redefines XML processing in Perl. It frees
you from the chains of SAX parser details. It elevates your soul. It
even freshens your breath. [think: DBI for XML]"
Basic XML and RDF techniques for knowledge management (IBM
developerWorks). Uche Ogbuji [84]shows how to add semantic knowledge
to an RDF application with WordNet synonym sets in the third article
in a series on IBM's developerWorks. "With the added knowledge of the
WordNet lexical database, you can search a set of RDF data for related
concepts, not just one keyword at a time. As the demonstration
issue-tracker application shows, that means searching once for
instances that fit within the concept of 'selection' rather than
searching individually on 'vote,' 'choice,' 'ballot,' and 86 other
related terms."
Miscellaneous
Jext 3.0 programmer's editor released. A new version of [85]Jext has
been released. " Jext is a powerful 100% pure Java programmer's text
editor. Mainly written for programmers, Jext was designed from the
ground up to suit your needs. From beginner to skilled coder, everyone
should find what they need in this editor." Jext features syntax
colorizing for ASP, C, C++, Eiffel, Python, Java, JSP, Perl, PHP,
HTML, TeX and XML. The [86]latest release features improved PHP
support. Jext has been released under the GPL license.
