XOTcl (XOTcl, pronounced exotickle) is an object-oriented scripting language based on MITs OTcl. XOTcl is intended as a value added replacement for OTcl.
XOTcl is an open source project which was initiated by Gustaf Neumann and Uwe Zdun, its main developers. The following people have contributed to XOTcl: Neophytos Demetriou, Fredj Dridi, Laurent Duperval, Teemu Hukkanen, MichaelL@frogware.com, Kristoffer Lawson, David LeBlanc, Catherine Letondal, Antti Salonen, Daniel Steffen, and Zoran Vasiljevic.
Scripting languages, like Tcl, are designed for glueing components together, provide features like dynamic extensibility and dynamic typing with automatic conversion, that make them well suited for rapid application development.
The basic object system of XOTcl is adopted from OTcl. The object system enables us to define objects, classes, and meta-classes. Classes are special objects with the purpose of managing other objects. ``Managing means that a class controls the creation and destruction of its instances and that it contains a repository of methods accessible for the instances.
Every object may be enhanced with object-specific methods. XOTcl supports single and multiple inheritance. All relationships in XOTcl, including class and superclass relationships, are completely dynamic and can be introspected. Through method chaining without explicit naming of the intended method, ambiguities in name resolution of methods are avoided. This way a shadowed method can be ``mixed into the execution of the current method.
XOTcl combines the ideas of scripting and object-orientation in a way that preserves the benefits of both of them. It is equipped with several new language functionalities that help building and managing complex systems. We added the following support:
Main features:
- Dynamic Object Aggregations, to provide dynamic aggregations through nested namespaces (objects).
- Nested Classes, to reduce the interference of independently developed program structures.
- Assertions, to reduce the interface and the reliability problems caused by dynamic typing and, therefore, to ease the combination of many components.
- Meta-data, to enhance self-documentation of objects and classes.
- Per-object mixins, as a means to improve flexibility of mixin methods by giving an object access to several different supplemental classes, which may be changed dynamically.
- Per-class mixins, as a means to improve flexibility of mixin methods to a class, all instances of the class have access to the mixed in methods like for multiple inheritance, but without the need of intersection classes.
- Filters (per class and per object) as a means of abstractions over method invocations to implement large program structures, like design patterns.
- Conditional Filters and Mixins can be used to perform context aware composition depending on guards (conditions which decide whether the interceptor should be used). All kinds of filters or mixins can be used conditionally.
- Dynamic Component Loading XOTcl integrates the Tcl package loading with architectrual support for integration with object-oriented constructs. Moreover, it provides tracking/tracing of component loading.

Areca is an Open Source file backup software developped in Java.
Main features:
- Archives Compression (Zip format)
- Archives Encryption (Triple DES encryption algorithm)
- Source file filters (by extension, subdirectory or regular expression)
- Incremental / Full backup support
- Archives content explorer
- Archive description : A manifest is associated to each archive, which contains various informations such as author, title, date, description, and some technical data.
- File history explorer : Areca keeps track of your files history (creation / modifications / deletion) over your archives.
- Backup simulation : useful to check wether a backup is necessary
- Archives merges / deletion : You can merge contiguous archives in one single archive or safely delete your latest archives.
- As of date recovery : Areca allows you to recover your archives (or single files) as of a specific date.
- Transaction mechanism : All critical processes (such as backups or merges) support a transaction mechanism (with commit / rollback management) which guarantees your backups integrity.
- Users actions history : Areca keeps an history of all users actions (archives deletion, merges, backups, recoveries).
- Archives indicators : Areca computes a lot of indicators for you, which will help you in the everyday management of your archives.

Clichart is an application intended for quick summarization and visualization of data, especially from system logs. It provides tools to extract and manipulate tabular summary data from text files, and to generate and view simple charts from tabular data on the command line
Main features:
- Display charts in a window, save them to disk (JPEG or PNG), or both
- Accept data in comma- or whitespace-separated formats
- Read data from a file, or have it piped into its standard input
- Display XY line charts, with the X axis based on dates, times or values. The Y axis must be simple values (integer or decimal)
- Be used interactively, or driven via scripts
- Generate summary data based on counts, averages, minimum, maximum of input fields
- Generate summary data based on discrete values
- Generate aggregates from tabular data
- Operate in CLI server mode, generating 1 or more charts based on commands passed via standard in (either from another script, or from a command file).
Enhancements:
- This release is mostly a tidy-up, with small bugfixes and improvements in handling errors.
- However, it also allows output from "aggregate" to include simple expressions, adds the ability for "cliserverlib" to locate "clichart" via the PATH (useful for Windows users), and uses the Psyco JIT compiler to speed operation if its installed.

Weka project is a collection of machine learning algorithms for data mining tasks. The algorithms can either be applied directly to a dataset or called from your own Java code.

Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. It is also well-suited for developing new machine learning schemes. Weka is open source software issued under the GNU General Public License.

Plone is an out-of-the-box ready content management system that is built on the powerful and free Zope Application server.
Plone CMS requires minimal effort to set up, is deeply flexible, and provides you with a system for managing web content that is ideal for project groups, communities and intranets.
Plone is a content management framework that works hand-in-hand and sits on top of Zope, a widely-used Open Source web application server and development system. To use Plone, you dont need to learn anything about Zope; to develop new Plone content types, a small amount of Zope knowledge is helpful, and it is covered in the documentation.
Zope itself is written in Python, an easy-to-learn, widely-used and supported Open Source programming language. Python can be used to add new features to Plone, and used to understand or make changes to the way that Zope and Plone work.
By default, Plone stores its contents in Zopes built in transactional object database, the ZODB. There are products and techniques, however, to share information with other sources, such as relational databases, LDAP, filesystem files, etc.
Plone runs on Windows, Linux, BSD, Mac OS X, and many other platforms; easy click installers are available for Windows and Mac OS X, and RPM packages are available for Linux. For full information, see Download.
Main features:
