DevelopmentGAFFitter: the Genetic Algorithm File FitterGAFFitter is a command line utility which can be run against directory trees to create groups of files that fit on media of a specified size:
Genetic Algorithm File Fitter (gaffitter) is a command-line software written in C++ that extracts --via
Genetic Algorithm-- subsets of an input list of files/directories that best fit the given volume size (target), such as CD, DVD and others. It is initially designed to run under Linux and POSIX systems, but easily portable to non-POSIX operating environment.
Using GA search, gaffitter improve different combinations of the files on the list so that the lost of space will be minimized. Ideal to be used for backups/records in CD, DVD and others.

Installation of GAFFitter was easy, the software was downloaded here in tar.bz2 form. Building involved the usual bunzip2, tar, make and make install steps. This all worked without problems on an Ubuntu Edgy Eft system that had the usual software build tools installed. The GAFFitter usage instructions give an idea of the various ways that the application can be run. An example run was tried on a collection of music files, GAFFitter did a good job of producing packed lists that would fit on a series of 700MB CDs. Version 0.5.1 of GAFFitter was announced on March 28, 2007: "This release fixes a bug (uninitialized variable) and changes the default behavior of GAFFitter, which now extracts the volumes as much as possible (unlimited iterations)." GAFFitter is a useful tool that can help to efficiently solve the problem of fitting large collections of files onto fixed-sized media. It is useful by itself, and can be incorporated into higher-level applications, as shown by this example integration script for the K3B multimedia utility. If you need to efficiently pack some files for archival, give it a try.
System Applications Database Software pgAdmin 1.6.3 releasedVersion 1.6.3 of pgAdmin is out with bug fixes. "The pgAdmin Development Team are pleased to announce the release of pgAdmin 1.6.3, the Open Source graphical PostgreSQL administration tool for Windows, Linux, FreeBSD , Mac OS X and Solaris".
SQLite 3.3.14 releasedVersion 3.3.14 of the SQLite DBMS is out. "This version focuses on performance improvements. If you recompile the amalgamation using GCC option -O3 (the precompiled binaries use -O2) you may see performance improvements of 35% or more over version 3.3.13 depending on your workload. This version also adds support for exclusive access mode."
Emulating Analytic (AKA Ranking) Functions with MySQL (O'ReillyNet)Stéphane Faroult discusses the emulation of analytic functions in MySQL on O'Reilly. "One of the most hailed extensions brought to SQL in recent years has been these functions that Oracle calls analytic functions, DB2 calls OLAP functions, and SQL Server 2005 calls ranking functions--but which MySQL, so far, still lacks. The good news is that they can be (relatively) easily and efficiently emulated."
Mail Software Postfix 2.5 snapshot 20070402Experimental release snapshot 20070402 of the Postfix 2.5 mail transfer agent is out. See the change log file for details.

A New, Improved Visualization for Web Server Logs (O'ReillyNet)Raju Varghese presents part two in a series on visualizing web server log files in 3D. "In my last article I showed how web server logfiles can be visualized as a 3D plot with the help of Perl and gnuplot. In this article we will enhance the plot in several ways. The main things we will introduce are color and evening out of the plot."
Desktop Applications Audio Applications JackMix 0.3 hits the shelfsVersion 0.3 of JackMix, a mixer application for the JACK Audio Connection Kit, is out with the following changes: "Inspired by a lot of talking during LAC I have redone the sliders. They still look kind of similar to some vu-meters but I think it isn't that bad anymore. But there are new knobs in this version too. They did get positive feedback during the conference. :-) The knobs from 0.2 didn't seem to scale well. At least not from the usability point. The biggest change is that version 0.3 saves the own state to xml-files which can be read again later. Also adding a filename on the commandline opens that file on startup. This enables version 0.4 to have lash-support."
QjackCtl 0.2.22 releasedVersion 0.2.22 of QjackCtl, the GUI control for the JACK Audio Connection Kit, has been released. This version includes bug fixes and other improvements.
Desktop Environments Creation of a new roadmap for GNOMEA new GNOME roadmap process is being discussed.

XML XInclude Processing in XSLTErik Wilde discusses XInclude Processing in XSLT on O'Reilly. "Assembling various parts of a document before processing the assembled document is a recurring theme in document processing. XML Inclusions (XInclude) is the W3C standard created to support this scenario, but since it is a standalone specification, it needs to be supported by a piece of software implementing this functionality. The XInclude Processor (XIPr), written in XSLT 2.0, implements XInclude and thus may help to reduce the dependency on numerous software packages if XInclude is used in an environment where XSLT 2.0 is used anyway."
