GNU ddrescue is a data recovery tool. GNU ddrescue copies data from one file or block device (cdrom, hard disc, etc) to another, trying hard to rescue data in case of read errors.
Ddrescue does not truncate the output file if not asked to. So, every time you run it on the same output file, it tries to fill in the gaps.
The basic operation of ddrescue is fully automatic. That is, you dont have to wait for an error, stop the program, read the log, run it in reverse mode, etc.
If you use the logfile feature of ddrescue, the data is rescued very efficiently (only the needed blocks are read). Also you can interrupt the rescue at any time and resume it later at the same point.
Automatic merging of backups: If you have two or more damaged copies of a file, cdrom, etc, and run ddrescue on all of them, one at a time, with the same output file, you will probably obtain a complete and error-free file.
This is so because the probability of having damaged areas at the same places on different input files is very low. Using the logfile, only the needed blocks are read from the second and successive copies.
The logfile is periodically saved to disc. So in case of a crash you can resume the rescue with little recopying.
Also, the same logfile can be used for multiple commands that copy different areas of the file, and for multiple recovery attempts over different subsets.
Ddrescue aligns its I/O buffer to the sector size so that it can be used to read from raw devices. For efficiency reasons, also aligns it to the memory page size if page size is a multiple of sector size.
Whats New in 1.5 Stable Release:
- The license has been updated to GPL version 3 or later.
Whats New in 1.6-pre2 Development Release:
- Support for sparse writes to the output file has been added.

LyX is an advanced open source document processor that encourages an approach to writing based on the structure of your documents, not their appearance. LyX lets you concentrate on writing, leaving details of visual layout to the software.

LyX runs on many Unix platforms, OS/2, and under Windows/Cygwin (this port requires an X server). LyX project can also run natively on Mac OS X, thanks to the Qt/Mac library.

LyX produces high quality, professional output -- using LaTeX, an industrial strength typesetting engine, in the background; LyX is far more than a front-end to LaTeX, however. No knowledge of LaTeX is necessary to use LyX, although it will give a user more power.

LyX is stable and fully featured. It has been used for documents as large as a thesis, or as small as a business letter. Despite its simple GUI interface (available in many languages), it supports tables, figures, and hyperlinked cross-references, and has a best-of-breed math editor.

EpiGrass is a simulator of epidemics over networks. EpiGrass is a scientific tool created for simulations and scenario analysis in Network epidemiology.
For an in depth description of Epigrass capabilities, please refer to the documentation.
EpiGrass can interact with the GRASS GIS from which it can obtain maps and other geo-referenced information. However, EpiGrass does not require an installation of the GRASS GIS for most of its features.
Epigrass is free-software, licensed under the Gnu public license (GPL).
Currently, EpiGrass is supported only on the Gnu/Linux platform. If you would like to see it run on other platforms, you can volunteer to oversee the porting to a given platform. Since Epigrass is written entirely in Python, porting to other platforms should be very easy. However this is not the main priority of the EpiGrass development team.
Enhancements:
- An import bug was fixed.

FreeNIBS is a loadable plugin for FreeRADIUS radius-server.
FreeNIBS provide authorization/authentication/accounting for Dialin (PPP/PPPOE/PPTP) users.
It can bee used for real-time prepaid and postpaid billing. FreeNIBS can bill users on service accuration, time, traffic and time&traffic.
FreeNIBS has very flexible settings for groups, users and prices. All data store in SQL-databases such as MySQl, PgSQL and Oracle.
FreeNIBS is covered by the GPL license.
Enhancements:
- Build error with FreeRadiuses 1.1.5-1.1.6 was fixed

Rextile project allows you to build XHTML documents and entire Web sites with ease.
You write text using Textile (a format much more concise than XHTML), automate document parts with Ruby scripting, and generate the site offline (the server gets static XHTML).
Rextile was inspired by Xilize. It uses RedCloth to convert Textile to XHTML, erb to run script blocks, and Hpricot for DOM manipulation.
Enhancements:
- Support for dt tags was added.
- Support for Debian-based Ruby (without gems) was improved.
- Minor fixes required by newer versions of RedCloth were made.

Taverna is a collection of workflow enactment and description components, including a high level language for workflows called Scufl (Simple Conceptual Unified Flow Language), a pure Java object model, parser to populate the model, and a set of views and controllers (including some Swing components to drop into your workflow-enabled applications). In order to actually run workflows you also need the myGrid workflow enactment engine.

Taverna core data models include the object representations of the workflow itself, all entities within the workflow (processors, ports, data links etc) and the model for the data values flowing along data links during a workflow enactment.

Taverna task extensions sit within an enactment engine - in this case FreeFluo - and provide concrete implementations of the abstract tasks specified by Processor objects within the workflow object model. It is these tasks which contain the logic required to contact web services, run local java classes and perform the other actions associated with their Processor entities.

Instances of the task extensions are created when a workflow and associated input objects are submitted through the Workflow Submission Interface. This interface may be an in process java method call or may be invoked across some transport such as SOAP in the case of a remote service based enactment engine. FreeFluo is capable of acting in both modes, the Taverna workbench incorporates an instance of the FreeFluo enactor to provide basic enactment services to users without a central workflow engine server.

The graphical user interface classes sit on a client machine and allow interaction with the core data model classes as well as with running workflow instance objects within an enactment engine. This allows workflow construction, editing and visualisation as well as enactor management and data browsing across the results and intermediate values within a workflow instance.

The storage interface is a plugable framework that allows external data and metadata stores to observe events within the workflow enactment service and collection information about those events. This could include a provenance collection plugin which watches the workflow enactment and records metadata about it in RDF form, or a storage plugin which streams results back to a relation database, possibly a Life Science Identifier (LSID) authority, as the enactment runs.

The LSID authority interface is a read only access point to data stored within a data store, and can potentially be used by the Taverna graphical user interface components to fetch results of previous workflows and make use of them as inputs to successive ones.

Kamaelia project aims to allow the BBC and others to create and test open protocols for large scale streaming.
Substantial subsystems include a core concurrency subsystem and the beginnings of an RTSP/RTP streaming server.
Existing functionality includes a complete single threaded, coroutine-based concurrency framework (Axon), a generic TCP client and server framework that allows protocols to be trivially created, a number of example protocols, and an Ogg Vorbis decoding subsystem for client site testing (libvorbissimple).
Enhancements:
- This release adds minor improvements to bring threaded component capabilities closer to those of ordinary components.
