Free the toolshed software for linux

The poldek project is the RPM packages management helper tool; its basic features are similar to every modern package updater like apt-get -- the program takes information about packages from package index file (packages.dir.gz by default) and allows packaging installation, upgrading and removal.
Package dependencies are automatically handled, so if you need to install a package which requires other packages to be installed, poldek downloads and installs all the required packages by itself.
Main poldeks advantages are:
- Relatively fast dependency processing
Package dependencies, conflicts and setting in order are handled by poldek itself without using rpmlib, so the program is significantly faster and uses less memory than rpmlib-based tools.
- "Smart" installation of a big package sets
Before their installation packages are divided into small groups, usually from 2 to 10 items (depending on their reciprocal dependencies). Each group is installed separately, which ensures that unsucessful installation of one of the groups doesnt influence other groups.
Another benefit of this separate installation is that it requires less memory and disk space than the usual one.
- Interactive mode
The poldek can work in two modes: a batch mode (in use similar to apt-get one) and interactive one. The interactive mode puts the user into a readline interface with command line auto-completion and history. In this mode the user is able to browse, search, download, install/upgrade and deinstall packages. In its concept it is similar to shell mode of Perls CPAN module (see sample interactive mode session).
- Installation system from scratch needs 8-12 MB memory only
During this type of install packages are downloaded and installed separately, so used memory size is independent of number of packages intended to install. Program is used by PLD Installer
- Quick package set verification for unresolved dependencies unneeded conflicts and dependency loops.
Feature is useful for distribution maintainers; see sample report.
- Division package set for the purpose of placing it on removable media (like CDROM or ZIP).
Program divide packages in the way that minimize needs of disk changes; for example if distribution fits on 3 CDs, then only 2 changes of CD disk are necessary during installation system from scratch. This feature is used for making PLD CD ISO images, see geniso-poldek script for details.
- Support for "patches" of package index
To save users time and bandwidth program supports "incremental indexes" which is very useful with repositories which frequently change. This feature consist in creation "patches" of index which gives the users possibility to update local index by download "patch" with information of changes only.
- Program is prepared to be run by ordinary user, installation of packages in that case can be done with sudo.
Enhancements:
- This is the first release after the poldek redesign.
- New features and significant changes include a new native package repository index format, support for Yum and XML Metadata repositories, improved support for APT-RPM indexes, a more user friendly interactive mode, proper packages ordering before their uninstallation, a clearer configuration syntax, a better dependency resolver, and many more.

The Kiwi Toolkit project is a foundation class library containing many useful classes that complement the Java Foundation Classes (JFC).
It includes many classes and components that were not provided with the JFC, such as a TreeTable component, a DateChooser, an MVC charting package (bar charts, line charts, pie charts), a plugin framework for Java, an application resource manager (for loading images, icons, HTML pages, audio clips, and other resources from JAR files), a better internationalization API, and much more.
Enhancements:
- This release adds some new classes and includes various bugfixes.

The Romalizer project is a Tcl script to analyze your MAME roms and report errors.
The ROMalizer is a Tcl script that examines your .zip files for MAME ROMs and lets you know if you have any extra data in them. It can also report incorrect filenames, CRCs, etc.
Enhancements:
- romalizer will no longer move the zipfiles it has fixed into your roms directory unless you specify the -M option. This will allow you to run romalizer as a normal user on a roms filesystem that is only writable by root or some other games administrator. If you use the -M option, romalzier will back up your old roms into the working directory as usual, if the -M option is not used, the new (fixed) roms will be located in the working directory.
- romalizer now fully supports two new styles of merging your roms. You may now use the -g or -G options to tell romalizer to use one of these new merging formats. When -g is used, romalizer will merge all clones into a single zip file. When -G is used, romalizer will create clone zip files that are capable of being run independantly of the parent romset. I have tested these new merging features on my pacman romset and it works beautifully, however more testing probably needs to be done on a complete romset for these options.
- neogeo games are now supported, romalizer will just ignore any CRC that matches 354029fc (ng-sfix.rom), 9036d879 (neo-geo.rom), and 97cf998b (ng-sm1.rom). Thus neogeo roms are now fully supported except for these 3 which should be placed in a file called neogeo.zip.
- romalizer requires usage of UnZip version 5.41 or higher due to a Y2K bug in UnZip. This patch will now check your unzip version and abort if you do not have a recent version of UnZip.

The Spider project is a complete object-oriented environment for machine learning in Matlab.
Aside from ease of use for base learning algorithms, algorithms can be plugged together and can be compared with, for example, model selection, statistical tests, and visual plots.
This gives all the power of objects (reusability, the ability to plug together, sharing of code), but also all the power of Matlab for machine learning research.
Enhancements:
- A WEKA interface was added, supporting decision trees.
- Additional code, documentation, and demos were added.

The Circle is an open source scalable decentralized peer to peer application. What does that mean? Well, theres no central authority running the show. No entry taxes either, no censorship, and (in theory) no weak point which can break the whole system.
No one even owns the source code. As long as there is one Circle peer running, anywhere in the world, theres still a network.
Main features:
- Share files
- Send instant messages and chat IRC-style
- Put together your own personalized, trust based news service
- Proxy Debian package downloads
The Circle is written in Python. It runs on Linux and Windows. (in fact, there is very little operating system specific code, so it will most likely work on any system that supports Python)
Scalability
At the core of the Circle is a decentralized hashtable, or "Chord". This table allows users to search for files in logarithmic time, based on keywords. This means that the Circle does not have the scalability problems of Gnutella style network (such as Kazaa, eDonkey), while also avoiding the need for a central server and therefore a single point of failure. Details of its operation are given in the "Technical Details" section below.
Privacy
The Circle does have the ability to post fully anonymous news a la Freenet. However, the file-sharing protocol isnt entirely anonymous. People will be able to work out your IP address.
In order to protect user privacy, the Circle includes a Digital Rights Management system. Although everybody can search your files by their keywords, you may choose which users are authorized to download them. An unauthorized third party has access only to the names of your files, not to their content. Needless to say, we expect you to use this system in order to prevent copyright infringement, while allowing private copy.
Note: If we become aware that you are trying to share snuff or child pornography, we will be able to work out your IP and from that your location and identity, and report you to the police and/or your ISP. Snuff and child pornography are things we think any reasonable person considers to be evil (its an issue quite separate from the debate over copyright).

The Parma Polyhedra Library is a modern C++ library providing numerical abstractions especially targeted at applications in the field of analysis and verification of complex systems.
The PPL can handle all the convex polyhedra that can be defined as the intersection of a finite number of (open or closed) hyperspaces, each described by an equality or inequality (strict or non-strict) with rational coefficients.
The PPL also handles restricted classes of polyhedra that offer interesting complexity/precision tradeoffs. The library also supports finite powersets of (any kind of) polyhedra and linear programming problems solved with an exact-arithmetic version of the simplex algorithm. (More details are available on the PPLs internal mechanisms.)
The Parma Polyhedra Library is: user friendly (you write x + 2*y + 5*z<<less
