Free considered software for linux

UTF8Script provides an additional binary format for Linux: scripts that start with a UTF-8 signature (aka BOM), i.e. with the byte sequence xefxbbxbf#!.

This is particularly useful for scripting languages that recognize the BOM, e.g. Python. With Python 2.3 or newer, scripts with the UTF-8 BOM are considered UTF-8 enocded without the need for an addition encoding declaration.

autonet.py is a small application which looks up existing network configuration files, probes the network with arping in order to determine if it can connect and ideally set up a working internet connection and routing.

If no internet connection is available, autonet.py will parse each configuration file, extract different network setups and probe if the network environment works with this configuration.

The probing is done with arping. A bogus IP 0.0.0.0 is used in order to get the network interface up. Then autonet.py tries to arping the gateway.

If the gateway responds the configuration is considered good. At this point there is no routing, so only hosts within the subnet defined in the configuration is used.

If none of the gateways in the configuration works, the probe gets more brutal by just setting up the network interface according to the configuration file, and and ping the gateway. Again, no routes yet.

If a configuration is considered working (gateway is pingable), the route is set as described in the configuration file. An internet connection should be established then.

This is also checked by pinging k.root-servers.org (as default, override with --testhost), use an IP address here, as DNS is not handled by autonet (yet?).

There is a special feature in autonet.py for owners of some models of Asus notebooks. The package contains a module which uses two LEDs of the laptop to show activity.

While searching and probing, the blue LED is flashing, if a working configuration is found the orange LED flickers for a second. Also this will only work if you have the asus module in your kernel, and it has *not* widely been tested. Have a look at Asus.py for details.

Some common vars can be edited in autonet.py, such as locations of required programs and some common settings (of which timeout does not even work yet) but in most cases supplying reasonable commandline arguments should be sufficient.

As Gentoo has slightly different settings, there are two scripts for Gentoo users, to make integration into the Gentoo init system easier.

Libdatastruct is an ANSI C library for abstract data types (ADT) and common algorithms. Since it uses some compiler specific optimization methods, it is compatible for any GCC (or compatible) compiler.

This helps the programmer focus on other, usually more important, aspects of the program, and not have to reinvent the wheel.

Memory has been considered a vital factor, so problems in its management have been (or tried to) avoided, therefore memory leaks, use of uninitialized memory, reading/writing invalid blocks, etc. are a constant preoccupation.

These are not original algorithms, they have been used for years, and are a fundamental part of computer science.

Installation:

make
make install

Usage:

compilation: cc program.c -ldatastruct -Wall -o program

Python Stencil Environment also know as PySE is a new python library for solving Partial Differential Equations with the Finite Difference Method (FDM).
This is still a quite new library, and the current release must be considered as beta software. It is quite rough around the edges, installation is manual and some minor dependencies are even missing in the released software. But as PySE already is functional, I have chosen to release the software.
PySE will be a component of PyFDM, a more complete package for working with finite difference methods in python. The functionality of PyFDM is not planned at the moment.
The requirements for PySE are: Python 2.4, numarray 1.3 or newer, Numeric 23.8 or newer, swig 1.3.24 or newer, and pypar 1.9.2. Older verions may or may not work!
Enhancements:
- Added a pdf with some documentation, examples and performance evaluation of PySE.

TocaRaul! is a playlist manager intended to be used with icecast2, and ices2 to stream ogg vorbis files over the network.
TocaRaul! is still in a very early stage of development, but it already has the basic functions to be considered usable.
This name is a tribute to Raul Seixas. He was a Brazilian rocknroll singer who died in 1989 by a heart attack. He still has many fans. Some of these fans use to scream "Toca Raul!!!" (in english its like: "Play Raul!!!") in many rocknroll shows (and other ones too) in Brazil.
Enhancements:
- Improvements were made to the addsong script.
- An entire album can be added to the playslist.
- An entire directory can be added to the database.
- A small play history was implemented.
- Many other minors improvements were made.

mailman-pop3d provides a POP3 interface to GNU Mailman for the purposes of deleting spam which is stuck in the administrative requests queue.
If you manage a large Mailman mailing list, and are tired of using the web interface to discard spam, this script may be for you.
This software should be considered to be in beta stage; bugs are possibly present, and bug reports would be very much appreciated. At this point, I would also be very interested in hearing about success stories.
Enhancements:
- Improved logging messages.
- Development status changed from alpha to beta.

Xwpe is a programming environment with a user interface that mimics the Borland C and Pascal family of products. The user interface mimics the Borland C and Pascal family of products for MS-DOS. From within xwpe you can edit, compile, and debug programs. Unfortunately Fred Kruse seems to no longer be a member of the on-line community.
The xwpe-alpha project was an attempt to continue development and bug fixes for xwpe. Since attempts to contact the author of xwpe have received no response, xwpe-alpha should be considered unsupported by Fred Kruse. Development has stopped recently.
Enhancements:
- A problem with compiling on Fedora core 4 was fixed.
- A .desktop file was added, so that it can be accessed from the applications menu.

jcrossclient is a client for the RPG/MMORPG Crossfire, written entirely in java.

Please note that this is an alpha release, and therefore should not be considered suitable for use as a main client (yet). Whilst most major bugs should now be fixed, there is no guarentee that this is the case.
