Free advantage software for linux

The Unidentified Flying Raw (UFRaw) is a utility to read and manipulate raw images from digital cameras. It can be used on its own or as a Gimp plug-in. It reads raw images using Dave Coffins raw conversion utility - DCRaw.
UFRaw supports basic color management using Little CMS, allowing the user to apply color profiles. For Nikon users UFRaw has the advantage that it can read the cameras tone curves. Even if you dont own a Nikon, you can still apply a Nikon curve to your images.
My guiding concept in the development of UFRaw is to give all the essential (and some inessential) information and control over the raw conversion, with the hope that one could resolve all the exposure and white balance issues during the raw conversion.
The obvious advantage is that one can make full use of the raw data. The provisional advantage is that this way we circumvent the current 8-bit limit of the Gimp, as UFRaw does all manipulations in 16-bits.
Main features:
- Embed EXIF information - EXIF data from Nikon NEF, Canon CR2 and Pentax PEF files is embeded in the output JPEG image. This feature is in its preliminary development stages and the EXIF data is only partially created. For other file types the EXIF data is completely ignored, which is a pity. If you are interested in saving the EXIF information, you should check the ExifTool by Phil Harvey.
- Support full color management workflow.
- Zooming and croping.
UFRaw was originally based on Dave Coffins plug-in and Pawel Jochyms plug-in with live preview. Joseph Heled also offers a Gimp plug-in with some interesting features like zooming and saving EXIF information.
UFRaw is licensed under the GNU General Public License. This means that you can use it freely. If you decide to use it, the only thing that Im asking is that you will drop me a line telling me what you think of it. I might create a database of supported cameras in the future, so it would be useful if youll tell me what camera you are using and if you would be willing to test UFRaws support of your camera in the future. You can find my e-mail address at the end of this page.
Enhancements:
- This is a bug correction version.
- Non-integer shrink factors are now handled.
- A crash which occurred when the spot selector reached an image boundary was fixed.
- Some TIFF images are no longer wrongly identified as raw files.

DeVeDe project creates video DVDs, suitables for home players.

DeVeDe can create video DVDs from any number of video files, in any of the formats supported by Mplayer.

The big advantage over other utilites is that it only needs Mplayer, Mencoder, DVDAuthor y MKisofs, so its dependencies are really small.

mpiBLAST is an MPI based parallel implementation of NCBI BLAST. The project consists of a pair of programs that replace formatdb and blastall with versions that execute BLAST jobs in parallel on a cluster of computers with MPI installed. There are two primary advantages to using mpiBLAST versus traditional BLAST.

First, mpiBLAST splits the database across each node in the cluster. Because each nodes segment of the database is smaller it can usually reside in the buffer-cache, yielding a significant speedup due to the elimination of disk I/O. Second, it allows BLAST users to take advantage of efficient, low-cost Beowulf clusters because interprocessor communication demands are low.

mpiBLAST achieves super-linear speedup in situations where the database is too large to fit into RAM, and near linear speedup in other situations. It does not require a dedicated cluster.

iTest project is a simple application which allows you to take advantage of the best of computerized examination.
iTest consists of two programmes:
- The Database Editor - question/answer database and exam server
- The Test Writer - the programme installed on each client computer
iTest makes it easy to:
- Create and organise a database of questions and answers
- Set up a server and a printer
- Connect a client computer for each student, which generates a test according to your server settings
Supported platforms:
- Linux/Unix
- Apple Mac OS X
- Microsoft Windows
Available in:
- English
- Russian
- Slovak
- Turkish
Enhancements:
Database Editor & Test Writer
- added Turkish translation
- if available, translation to the system language loaded by default
- NEW ENCODING: UTF-8 adds support for more languages and special characters
- iTest 1.1.1 can still open old CP 1250 databases from older versions of iTest
- older versions of iTest cannot open the new UTF-8 databases from iTest 1.1.1
- upgraded from Qt 4.2.2 to Qt 4.3.0
Database Editor
- printing: support for the & sign

Apache Portable Runtime (APR) project mission is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform-specific implementations.
The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features.
Main features:
- Atomic operations
- Dynamic Shared Object loading
- File I/O
- Locks (mutexes, condition variables, etc)
- Memory management (high performance allocators)
- Memory-mapped files
- Multicast Sockets
- Network I/O
- Shared memory
- Thread and Process management
- Various data structures (tables, hashes, priority queues, etc)
Enhancements:
- Various bugs were fixed.
- The API compatible with version 1.2.7.
