Free grey matter brain software for linux

smf-grey is a Sendmail milter that implements the GreyList Anti SPAM technology.
This technology can significantly reduce the amount of SPAM and viruses going from zombie computers (infected Windows PC), which produce more than 80% of SPAM.
GreyList Sendmail milter has a very effective GreyList algorithm on the base of the tuple: sender IP address (C class subnet), sender envelope and recipient envelope.
Its very recommended to use the smf-grey milter combined with the smf-zombie and the smf-spf milters. Its a triple impact on SPAM and viruses, that will seriously increase the efficiency of filtration.
This milter aims to be lightweight, reliable and simple. Its written in C.
Main features:
- It has a hosts/networks whitelist;
- It has an autowhitelist;
- It can add the information header with GreyList results to scanned messages;
- It can log all milter activities through the syslog service.
Advantages:
- Small code;
- Fast work;
- Stability (production quality);
- Few system resources are required.
Enhancements:
- Whitelists auto reloading was implemented.
- Autowhitelisted records regular dumping and reloading was implemented.
- The default greylisting time period was increased.
- New TODO tasks were added.
- Cosmetic enhancements were made.

Flate library is a template library used to deal with html code in CGI applications. The library includes C and Perl support. All html code is put in an external file (the template) and printed using the library functions: variables, zones (parts to be displayed or not) and tables (parts to be displayed 0 to n times).
Using this method you dont need to modify/recompile your application when modifying html code, printing order doesnt matter in your CGI code, and your CGI code is much cleaner.
Enhancements:
- can now include external files with #INCLUDEFILE /path/to/file.html

gbrainy is a brain teaser game and trainer to have fun and to keep your brain trained.

The application is written for GNOME using Mono, C# and Cairo.

gbrainy mission is to provide a platform for creating different kinds of brain-teasers and brain trainers games for GNOME.

Use cases:

Currently the following use cases are considered:

New user.A person that uses gbrainy to evaluate it and understand what can provide. Interested in see its different kinds of games in a short period of time.

Adult gamer.An adult that uses gbrainy just for fun.

Adult training.An adult that uses gbrainy to train her memory, arithmetical and logical capabilities.

Kid training.Her parents decided that she should use gbrainy to train her memory, arithmetical and logical capabilities.

The objective is to provide enough flexibility in terms of number of games and difficulty parametrization to make gbrainy use on these cases straight forward.

DTI stands for Diffusion Tensor Imaging and is a magnetic resonance imaging method that can be used to measure local information about the structure of white matter pathways within the human brain. Combining DTI data with the computational methods of MR tractography, neuroscientists can estimate the locations and sizes of nerve bundles (white matter pathways) that course through the human brain. DTI-Query allows neuroscientists to place and interactively manipulate box-shaped regions (or volumes of interest) to selectively display pathways that pass through specc anatomical areas.
Enhancements:
- Improved support for tensor data formats. (Now supports 5D tensor files, and arbitrary ordering of tensor indices.) Has been tested with tensor image files output by the AFNI tools: http://afni.nimh.nih.gov/sscc/dglen/DTIQuery
- Support for Mac OS X (Carbon)
- Binaries released for Windows, Linux (32- and 64-bit), and MacOS X (PPC and Intel)
- Added choice of integration method (Eulers method, Runge Kutta 2nd order, Runge Kutta 4th order) for STT tracking.
- Improved support for reading NIFTI background images (correctly handles q-form/s-form matrices).
- Can now save visible pathways (as a binary format, or as a NIFTI mask image).
- Many minor GUI enhancements and bug-fixes.

Coriander project is the Linux graphical user interface (GUI) for controlling a Digital Camera through the IEEE1394 bus (aka FireWire, or iLink).
Coriander is full featured and besides changing the parameters of the camera it will also let you record video, send images to an FTP site, convert the video to a V4L stream,... A live display is of course provided too.
Best of all, Coriander will work with any camera that is compatible with the IIDC specifications (also known as DCAM specs). This includes most 1394 webcams and a majority of industrial or scientific cameras too.
However, any cameras in which you can insert a video tape (camcorders,...) will NOT work with coriander. These cameras record compressed DV video on the tape, while the IIDC specify uncompressed, on-the-fly video flows.
Main features:
- change picture mode and format.
- camera on/off/reset
- control of Auto/man/one-push-auto, on/off, value and absolute value for all standard features
- memory channel save/load
- full Format_7 control
- control of the external trigger
- transmission on/off/restart
Enhancements:
- Upgrade the framerate calculation to use the timestamps sent by the kernel (through libdc1394)
- Add a counter that shows dropped frames warnings. A warning is issued when the difference between a pervious period and a new period is larger than 50%.
- fixed the bit depth. If the bit depth is available in the camera, it will be used. Otherwise the manual control will be available. I still have problems with my Basler 602f though. It has 10bits but the image is not good: saturated regions appear mid-grey (128) and the other regions are noise.
- sync with libdc1394 (SVN 391)
- fixed missing string in trigger_source_list
- sync with libdc1394
- add more details to configure messages
- added PIO, SIO and strobe direct register read/write
- remove spurious debug messages
- revert part of the change of Feb. 1st regarding the Flea 2 because some other manufacturers implementation systematically fail one of the tests.
- fixed wrong argument order of WritePVNHeader(). Thanks to John Shen.
- Disable features if they dont support any control mode or if they are OFF and their power cant be controlled. This solves a few issues we had with the Flea 2 from Point Grey.
- little update of the "About" window
- dont set 1394b at boot time: let the user do it manually.
- move and fix `extern declarations of string arrays from build_menus.c, build_ranges.c, thread_save.c, tools.c, update_frames.c and update_ranges.c to coriander.h

MajorTeach project is a mnemonics practicing tool with documentation.

MajorTeach is a Perl script with documentation that teaches the Major System, a Mnemonics system that allows you to remember (in your brain, without additional hardware) long lists of knowledge (100 to 100,000 items long) in order, as well as long numbers, like tax ID numbers, phone numbers, credit card numbers, etc.

SQLgrey is a Postfix greylisting policy service with auto- whitelisting and an SQL database as storage backend.
The project is based on postgrey, refining auto-whitelisting and storing whitelists and connection attempts in a database. Its goal is reducing the amount of spam reaching user mailboxes.
Main features:
- SQLgrey can withstand a database crash (grey-listing is automatically switched off)
- 3 grey-listing algorithms to choose from
- Support for file-based IP and FQDN whitelists
- Support for fetching up-to-date whitelists from a repository
- Can mail the admin when the database is unavailable
- Auto-whitelists now understand SRS (SPF-aware mail forwarding)
- IPv6 support
- OPTIN / OPTOUT support
- Fine log controls
- Activity reports
