Xscreensaver will run several programs to continuously update the screen instead of going blank. You can specify the programs and their arguments using resources. You can also add dpms (power saver) options. Xscreensaver will make use of any installed OpenGL libraries, such as Mesa (also in the ports collection). The client-server model employed by xscreensaver make it a superior choice to xlock, since no separate auto-locking program is needed. It's also extremely easy to add new programs like xearth, or any other program that can fill the root window as additional screensavers.

The xcb-util module provides a number of libraries which sit on top of libxcb, the core X protocol library, and some of the extension libraries. These experimental libraries provide convenience functions and interfaces which make the raw X protocol more usable. Some of the libraries also provide client-side code which is not strictly part of the X protocol but which have traditionally been provided by Xlib. These libraries are currently included, roughly ordered by maturity: aux: Convenient access to connection setup and some core requests. atom: Standard core X atom constants and atom caching. property: Callback X property-change handling. event: Callback X event handling.

Fbpanel is a lightweight, NETWM compliant X11 desktop panel. It works with any NETWM compliant window manager (xfwm4, sawfish, openbox, metacity, etc.) It currently provides and features: - Taskbar, launchbar, and pager - Show desktop button (iconify or shade all windows) - Image viewer and volume control - Text and digital clock - System tray (notification area) - Menu with support for freedesktop.org application menu - CPU, network, memory, and battery monitors - General monitor (to display output of configured command) - Ability to replace windows' icons - Transparency support - Customizable size and screen position - Ability to run many instances each with its own configuration - Modest resource usage

HA is an archiver which I released in January 1993 as version 0.98. After that I had plans to improve speed, archive handling etc. which would have required total rewrite of the code. For that I unfortunately could not find time. Because there has been quite considerably interest for internals of HA (especially for the HSC compression method) I decided to make a source level release from my current test version (0.999 beta) and place it under GNU General Public License. The sources for this version are not very consistent or clean, but everything should work. There are several improvements which should be made before this could be called version 1.0. Some of the most obvious of these are: - Compression methods should be coded in assembler for PC and using more efficient data structures for 32 bit platforms. Current version does some things only to overcome 64kB segments of 8086. - UNIX port has still some problems and is missing some things (for example a grouping operator in wildcard matches). - File handling is far from optimum. - Archive handling is not too clever either. - Testing should be done more thoroughly as there are many special cases in compression routines which get used very rarely. - Documentation of code and algorithms is totally missing.

This program is designed to match up items in two different lists, which may have two different systems of coordinates. The program allows the two sets of coordinates to be related by a linear, quadratic, or cubic transformation. There was a major change in version 0.15: the first stage uses the clever method of finding the most likely triangles described in Tabur, Publications of the Astronomical Society of Australia, vol 24 , page 189 (2007). This replaces the more brute-force-ish method of Valdes et al., Publications of the Astronomical Society of the Pacific, vol 107, page 1119 (1995), which was employed in version up to 0.14. The program was designed and written to work on lists of stars and other astronomical objects, but it might be applied to other types of data. In order to match two lists of N points, the main algorithm calls for O(N^6) operations (yes, that's N-to-the-sixth), so it's not the most efficient choice. I find myself becoming impatient for N >= 100, but your mileage may vary. On the other hand, it does allow for arbitrary translation, rotation, and scaling...

OptimFROG is a lossless audio compression program. Its main goal is to reduce at maximum the size of audio files, while permitting bit identical restoration for all input. It is similar with the ZIP compression, but it is highly specialized to compress audio data. OptimFROG obtains asymptotically the best lossless audio compression ratios. It has Windows, Linux, and Mac versions, fully featured input plug-ins for the Windows Media Player, foobar2000, Winamp2/3/5, dBpowerAMP, XMPlay, QCD, and XMMS audio players (with bitstream error resilience, ID3v1.1 and APEv2 read tagging support, ID3v2 compatible), optimal support for all integer PCM wave formats up to 32 bits and an extensible streamable (error tolerant) compressed format. It is also fast, the default mode encodes CD quality audio data at 12.4x real-time and decodes at 17.4x real- time on AMD Athlon XP 1800+ (the fastest mode encodes at 28.1x real-time and decodes at 24.7x real-time). Self-extracting (sfx) archives can also be created with a small overhead of just 54 KB.

Gerber Viewer (gerbv) is a viewer for Gerber files. Gerber files are generated from PCB CAD system and sent to PCB manufacturers as basis for the manufacturing process. The standard supported by gerbv is RS-274X. The basic difference between RS-274D (the old standard) and RS-274X is basically the addition of apertures in RS-274X. It might be possible to make an RS-274X file out of an RS-274D file and an aperture list. gerbv also supports drill files. The format supported are known under names as NC-drill or Excellon. The format is a bit undefined and different EDA-vendors implement it different. But basically you need to have the tools definition in the file, then the parser is quite tolerant. The different holes are shown as dots in the (scaled) correct size. The different layers of the PCB are separated into different files. gerbv can load all files at the same time and display them "on top of each other". You can independently turn them on and off.

The EAGLE Layout Editor is an easy to use, yet powerful tool for designing printed circuit boards (PCBs). The name EAGLE is an acronym, which stands for Easily Applicable Graphical Layout Editor. The program consists of three main modules: o Layout Editor o Schematic Editor o Autorouter which are embedded in a single user interface. Therefore there is no need for converting netlists between schematics and layouts. This is a Light Freeware Edition. It has the following limitations: o The useable board area is limited to 100 x 80 mm (4 x 3.2 inches). o Only two signal layers can be used (Top and Bottom). o The schematic editor can only create one sheet. o Support is only available via email or through our forum (no fax or phone support). o Use is limited to non-profit applications or evaluation purposes. Apart from these limitations the EAGLE Light Edition can do anything the Professional Edition can do. You can even load, view and print drawings that exceed these limits!
