Free alternative software for linux

Alternatives system is an implementation of a Debian alternatives system; a system that allows several programs with the same or similar functions to be installed on a single system at the same time.
This implementation solves some problems and limitations of original implementation.
Alternatives architecture
General engine:
- alternatives-auto - turn into auto mode some alternatives item
- alternatives-manual - turn into manual mode some alternatives item
- alternatives-update - update current state of alternatives symlinks
Special scripts for the packages:
- alternatives-install - register new alternatives config, for use in %post package script
- alternatives-uninstall - unregister some alternatives config, for use in %preun package script
ALT Linux specific:
- alternatives-helper - helper script to use in package scripts
- alternatives-upgrade - tool to upgrade from old config format (XML based) to new.
Directories:
- /usr/bin - all scripts live here
- /etc/alternatives/packages.d - all package configs
- /etc/alternatives/auto - symlinks to registered configs
- /etc/alternatives/manual - list of alternatives in manual mode
- /etc/alternatives/links - for internal use only, alternatives symlinks lives here
- /usr/share/alternatives - directory with some helper functions and scripts
Original Debian alternatives implementation has some limitations and problems, so we (ALT Linux Team) rewrite this subsystem. What changes we have made?
- You dont need to give special generic name for altenatives file. This name is autogenerated now.
- This version is written in shell, awk and sed , so we reduce a number of dependencies, therefore, number of the packages in basesystem.
- We use different update model. Original alternatives system maintains its own database, by creating/removing files in system. In our alternatives (rpm) packages contains its configs and places them into generic directory during package installation. After package removal its config is automatically removed. It works like Debian menu subsystem, and its more stable.
- Now we have not any limitations for master-slave hieracly depth.
- New alternatives system works with no groups, but with each item. You can turn into manual mode any available item. There are only one difference between master and slave: weight calculation algorithm. Slave alternative have same weight as a master alternative.
- alternatives-update script corrects invalid manual alternatives, by switching them into auto mode. In original alternatives was situations with broken symlinks. Also new system doesnt create symlinks if target file does not exist. As a result, we also reduce number of broken symlinks.

KDE 3.5.x Alternate logout package is an alternative logout for KDE, background wipe, based on shadowfade patch http://kde-apps.org/content/show.php/shadowfade+at+logout+for+KDE+3.5.x?content=35731

It is provided as patches for KDE 3.5.6 (kubuntu), but can be easily adapted to other distros as well.

When patch is in effect, it is possible to control speed/opacity/greylevel on wipe, and revert back to default logout if needed.

Use following settings in ~/.kde/share/config/ksmserverrc:

------- snip -------
[Logout]
doFancyLogout=0/1 (new fade on/off)
doUbuntuLogout=0/1 (new gui on/off)
doFancyLogoutAdditionalDarkness=0.6 (default value is a double)
doFancyLogoutFadeTime=4000 (in ms, fade in)
doFancyLogoutFadeBackTime=1000 (in ms, fade out on cancel)

The Useful Terminal I/O library is a an alternative to ncurses for working with terminfo-defined terminals.
Included are raw terminfo string access and output, an efficient buffered output system, and a keyboard driver.
Enhancements:
- This release fixes some problems when running under 2.6 kernels and some CGC crashes caused by incorrect clipping.

The Useful Terminal I/O library is a C++ alternative to ncurses for working with terminfo-defined terminals. Included are raw terminfo string access and output, an efficient buffered output system, and a keyboard driver.

Installation:

./configure
make
make install

./configure --help lists configuration options, like setting an installation path other than /usr/local. To use the library, include utio.h and link with -lutio. Look at the example programs in the demo directory to start with something that is known to work.

File Lister provides a Web interface for listing files and directories.

FileLister is meant to be an open source alternative for listing files/directories with an easy navigateable (web-)interface.

Visualboy Advance is one of the best GBA emulator for Linux.

Featuring great speed, excellent compatiblity, sound support, savestates, cheat functions, and multiple languages.

Recently, new GTK+ GUI has been added to VBA as an alternative for SDL version. You really cant go wrong. A must-try!

Test::use::ok is an alternative to Test::More::use_ok.

SYNOPSIS

use ok( Some::Module );

According to the Test::More documentation, it is recommended to run use_ok() inside a BEGIN block, so functions are exported at compile-time and prototypes are properly honored.

That is, instead of writing this:

use_ok( Some::Module );
use_ok( Other::Module );

One should write this:

BEGIN { use_ok( Some::Module ); }
BEGIN { use_ok( Other::Module ); }

However, people often either forget to add BEGIN, or mistakenly group use_ok with other tests in a single BEGIN block, which can create subtle differences in execution order.

With this module, simply change all use_ok in test scripts to use ok, and they will be executed at BEGIN time. The explicit space after use makes it clear that this is a single compile-time action.

lamefwd provides an easy-to-use single process port forwarder.
lamefwd is an easy-to-use single process port forwarder, handling both TCP and UDP protocols. It is intended to be a fast and lightweight alternative to portfwd.
Usage
On BSD and Linux use "./configure ; make", on Windows run the installer. Then just edit lamefwd.cfg before starting the program:
#
# example config file for lamefwd
#
# localport remotehost remoteport protocol
#
5000 test.host.se 50 tcp
5005 test.host.se 55 udp
Enhancements:
- This release adds support for automated building using "./configure ; make" on *BSD, Linux, and Cygwin systems.
