DevelopmentUrwid, a Console UI library for PythonUrwid is a terminal-based user interface library for the Python language that is reminiscent of the old Unix curses terminal control library. Urwid is used for implementing user interfaces that work with simple ASCII terminals.
There is also an online web_display module live demo site for those who wish to test Urwid in action. Installation is quite simple, packages are available for Debian-based systems, and a simple setup.py script is provided for other platforms. A number of useful demo programs are included for testing and reference. Demos include a directory browser, a numerical calculator, a text editor, a test suite, a fibonacci generator and a package tour, see the screenshot and programming examples for some images. Your author was able to run all of the demos with no trouble. Version 0.9.0 of Urwid was released this week: "This is the first release of Urwid with UTF-8 input and display support. A new raw_display module was added to enable UTF-8 display. This module also fixes the "dead corner" in the bottom right of the screen and improves legibility of bright text in some terminals." Urwid is a useful tool for applications that need the portability offered by a text-only user interface, it fills a void between full-fledged GUI applications and a simple command line interface. Being Python-based, it is portable, easy to install, and simple to use.

Desktop Environments Accelerated Indirect GL XNow there are two 3D-enhanced X servers available: some Red Hat hackers have released some code which they call Accelerated Indirect GL X, or AIGLX.

Circuit Design on Your Linux Box Using gEDA (Linux Journal)Linux Journal reviews gEDA, a collection of electronics tools. "A lot of attention-and hype-has focused on bringing traditional office-productivity programs, such as the OpenOffice.org suite, to Linux. However, another important-and far less-hyped-area where Linux's desktop abilities come to the fore is in engineering software, and in particular, CAD (computer-aided design). Non-engineers tend to think of the term CAD as referring to mechanical design software, and they are partially right. We are used to seeing complicated drawings of mechanical assemblies appearing on computer screens in advertising and television. However, CAD doesn't mean only mechanical design. Electronics designers also long have used computer-based design tools to help them perform their design tasks."

Perl Managing Rich Data Structures (O'Reilly)Dave Baker uses perl to work with Rich Data Structures on O'Reilly. "If you're like me, you've written plenty of scripts that use simple text files to store snippets of data. Those scripts might have evolved over time into using several snippets of data for each item, which translates into lots and lots of little text files in a data directory somewhere. After reading that Linux doesn't like more than a hundred or so text files per directory, and thinking about the amount of space wasted on my hard drive due to the small size of the snippets compared to the size of a sector and the hassle of all those little files when making a backup, I decided to move from snippets to a single database. Here's how I did it."
