Free not easily broken software for linux

EasyChem is a program designed to draw chemical molecules, written under Linux and using Gtk+ 2.
Main features:
- Drawing very easily ornaments (non-bonding electron pairs, ...)
- EPS exporting with LaTeX fonts (Computer Modern)

Not A Commander is yet another file manager modeled after the Norton Commander. Good integration with the command line is the primary goal.
This project is using the technology of Natural Stupidity for development: first get something working at all, then gradually improve it. My primary targets are the features that I personally would use. The features that I wont use anyway are not planned to be implemented at all (though if someone would contribute an implementation I would gladly accept it - as long as it does not break any of the things that I use).
Build
Run `make. That should build all the binary parts. The X11 headers are required for build. You may need to modify the Makefile for peculiarities of your particular system (directory names, libraries etc.).
Installation
Run `make install. By default the `nac binary is instaled into /usr/local/bin and the rest of files is installed into /usr/local/lib/nac (which is referred further as "the NAC directory").
These directory names can be changed in the Makefile. If the configuration file nac.sysrc was present in the NAC directory before installation, it will be moved into nac.sysrc.old.
Configuration
The default configuration of NAC can be changed with rc files. There are two rc files:
per system - nac.sysrc in the NAC directory per user - .nacrc in the users home directory
These files are common Tcl scripts that can be used to change the tunable values. NAC first sets the built-in values, then loads the system-wide rc file (if present), then loads the users rc file (if present). Thus the system-wide script can examine the built-in values and modify them was neccessary, and the users script can do the same thing with the result
of the system-wide script.
Be careful with the syntax, in case of an error in the rc scripts NAC wont start.
The list of the supported tunables and their values can be found at the top of tune.tcl. For now (the alpha phase of development) its expected to be quite liquid and change between snapshot releases. Probably some sort of versioning will be added after it stabilizes.
The sample system rc file included in a release contains only one setting - the name of font to use (most probably you dont have the font "koi9x16" which is the built-in default).
The default initial size of the window is defined by panel dimensions, variables named set panel:filespercolumn (number of rows in panels), panel:ncolumns (number of columns in panels), panel:columnwidth (width of a column in dots). The internal xterm is automatically resized to fit these dimensions. Alternative size in pixels or xterm characters can be
selected with command line options.
Enhancements:
- Various bugs were fixed and workarounds were included for bugs in glibc and Tk.

Asymptote is a powerful script-based vector graphics language that provides a natural coordinate-based framework for technical drawing.
Asymptote has labels and equations that are typeset with LaTeX, for high-quality PostScript output.
A major advantage of Asymptote over other graphics packages is that it is a programming language, as opposed to just a graphics program: it can therefore exploit the best features of script (command-driven) and graphical user interface (GUI) methods.
Main features:
- inspired by MetaPost, with much cleaner, powerful C++-like programming syntax and numerics;
- mathematically oriented (e.g. rotation of vectors by complex multiplication);
- LaTeX typesetting of labels (important for document consistency);
- compiles figures into virtual machine code for speed without sacrificing portability;
- uses simplex method and deferred drawing to solve overall size constraint issues between fixed-sized objects (labels and arrowheads) and objects that should scale with figure size;
- high-level graphics commands are implemented in the Asymptote language itself, allowing them to be easily tailored to specific applications;
- provides a standard for typesetting mathematical figures, just as TeX/LaTeX has become the standard for typesetting equations.
Enhancements:
Routines to find the 3D and projected 2D bounding boxes of Bezier surfaces
were added to the surface module, along with the standard teapot example.
Extended for loops were documented. The page numbering of slide
presentations with stepping enabled was fixed. The int type is now a long
long type (typically a 64-bit integer). Support for reading and writing
64-bit integers in binary and XDR modes and large file support were added.
Input files are now opened in input-only mode. Multiple invocations
of labelpath now work. A projection bug in the grid3 module was fixed.
The search path order was changed: directories specified by the dir
configuration variable are now examined before the .asy subdirectory in the
users home directory. User configuration files are ignored during
installation. Some bugs in asy-mode.el were fixed. Texput files are
removed again. A memory allocation incompatibility in the workaround for
old, broken readline libraries was fixed. The framepoint and truepoint
routines now work even when an exact picture size estimate is unavailable;
a picture scaling bug was fixed. Writing to a file specified with
-o /dir/file.eps is allowed again. A quarticroots solver was added, the
cubicroots solver was improved, and a complex quadraticroots solver was
added. A workaround for broken texi2dvi installations was implemented.
Memory leaks were fixed. The garbage collector was update to gc-7.0;
upgrading to gv-3.6.3 is also recommended. A segmentation fault in
complement was fixed.

GnomeICU project is one of the most popular UN*X-based ICQ programs in the world. Internet chatting has quickly become one of the most popular uses of the Internet - second only to Email.
Instant messaging allows users to communicate in real time with friends, family members, and coworkers in an efficient, unobtrusive manner.
Main features:
- Server-side list storage
- Basic messaging
- File transfer (temporarily broken due to protocol change)
- Contact history
- Visible/Invisible/Ignore lists
- Ability to interface ICU from the command line
- Icon themes
- and many, many more.

Nagios (formerly Netsaint) is a daemon written in C that is designed to monitor networked hosts and services.
Nagios project has the ability to notify contacts (via email, pager or other methods) when problems arise and are resolved. Host and service checks are performed by external "plugins", making it easy to write custom checks in your language of choice.
Several CGIs are included in order to allow you to view the current and historical status via a Web browser, and a WAP interface is also provided to allow you to acknowlege problems and disable notifications from an internet-ready cellphone.
Main features:
- Monitoring of network services (SMTP, POP3, HTTP, NNTP, PING, etc.)
- Monitoring of host resources (processor load, disk and memory usage, running processes, log files, etc.)
- Monitoring of environmental factors such as temperature
- Simple plugin design that allows users to easily develop their own host and service checks
- Ability to define network host hierarchy, allowing detection of and distinction between hosts that are down and those that are unreachable
- Contact notifications when service or host problems occur and get resolved (via email, pager, or other user-defined method)
- Optional escalation of host and service notifications to different contact groups
- Ability to define event handlers to be run during service or host events for proactive problem resolution
- Support for implementing redundant and distributed monitoring servers
- External command interface that allows on-the-fly modifications to be made to the monitoring and notification behavior through the use of event handlers, the web interface, and third-party applications
- Retention of host and service status across program restarts
- Scheduled downtime for suppressing host and service notifications during periods of planned outages
- Ability to acknowledge problems via the web interface
- Web interface for viewing current network status, notification and problem history, log file, etc.
- Simple authorization scheme that allows you restrict what users can see and do from the web interface
Enhancements:
- Fix for incorrect performance data file write/append mode options
- Fix for current status of hosts with no host check command defined
- SIGSEGV signals should now be logged again (broken in 2.8)
- Configure script fix for no mail program found/installed on system
- Configure script option bug fixes for cygwin and embedded perl
- Command definitions and host/service plugin perfdata with HTML should now be escaped in CGIs
- Patch for incorrect time down percentage in availability CGI
- Updated init script to fix a race condition during restarts

GAI Leds displays the keyboard status leds.

This is a simple applet that displays the status of the keyboard leds. Useful for us that have a wireless keyboard without the leds.

Installation:

Simply do:

./configure
make
make install

It requires the GAI library (General Applet Interface) and you can find it at http://gai.sf.net together with other applets.

If you use gnome, this applet will be in the applet menu under "Accessories".

It seems like XFree86 4.3.0 doesnt register Scrollock like earlier versions. Or maybe it is just my settings that are broken. Any ideas?
