Free yet another messenger software for linux

Yet Another Autoresponder (yaa) is an email (vacation) autoresponder that is able to fetch autoresponse data from various sources, using separate plugins for each source type.
Yes, i wrote yet another mail autoresponder daemon. Why? Becouse i was looking for mail autoresponder daemon, which would be easily extendable and would work with Postfix virtual delivery daemon virtual(8). Unfortunatly i was not able to find something like that on the internet, thats why I wrote it in Perl.
Main features:
- Fetches autoresponder data (subject, message, etc...) using plugins
- Currently developed plugins: SQL, LDAP, DB_File, BerkeleyDB, PCRE, STATIC
- It can forward entire original message to the per-recipient custom tunable email address
- Doesnt respond to mailing list posts and posts, that could couse autoresponder deadlock.
- Autoresponse messages can be in any charset.
- Single, all-in-one configuration file
- Can act as SMTP or LMTP server in daemon mode

Yet Another Calendar is a malleable, clear, concise CGI calendar. Yet Another Calendar project doesnt require a relational database server and uses a single page per month for editing and viewing.
Main features:
- XML/RSS export
- Palm datebook (.pdb) export
- Text export (tab delimited file)
- Single page for editing and viewing
- Optional start and end times for all events
- Edit history/change tracking (with an rcs cron job)
- Archiving of old events (also with a cron job)
- Small amount of source code (under 500 lines)
Enhancements:
- There are now links on the calendar for an XML/RSS feed, a Palm datebook (.pdb) file, and a tab delimited text file.
- A few minor bugfixes and enhancements were made.

Yet Another Dynamic Engine (YADE) is an extensible framework that is designed with dynamic libraries in a way that it is easy to add new numerical models and objects.
There are four different models: Discrete Element Method based on spheres, a second method based on tetrahedra, modelling with lattice elements, and Finite Element Method.
Various different methods and algorithms for numerical simulation currently exist. Yade tries to extract their underlying abstractions using following examples:
- Finite Element Method (FEM, [2]),
- Discrete Element Method (DEM),
- Coupling FEM with DEM,
- Mass Spring System,
- Lattice Beam Model,
- Tetrahedron Discrete Model.
Those abstractions are implemented in C++ conforming to Object Oriented design principles. They provide interface to plug-in different modelling methods.
Yade framework is intended to work with other numerical methods than those mentioned above.
Advantages:
- allows numerous simulation methods in the single framework, so coupling them becomes possible,
- plugins can import data from other software,
- thoughtful code design promotes code reuse and improvement,
- open source development model allows community feedback.
Disadvantages:
- implementing models requires adhering to framework design,
- Yade framework is a new emerging software, still in beta phase.
- if you know more disadvantages, let us know!
Enhancements:
- This release has major improvements in the code, and directory cleanup was done.
- The build system was changed from qmake to scons.
- A complete Lattice Geometrical Model was added as a result of PhD defense by one of yades authors.
- Several improvements in Discrete Element Method, capillary law, and triaxial test.
- Among smaller improvements, it is possible to select bodies by clicking them and moving around with the mouse.
- Interaction forces are drawn between bodies, and can be seen as bars with strength related to bar thinckness.

Voice, video, data and instant messaging can all be unified under Yates flexible routing engine, maximizing communications efficiency and minimizing infrastructure costs for businesses.
Main features:
- VoIP server
- VoIP client
- VoIP to PSTN gateway
- PC2Phone and Phone2PC gateway
- H.323 gatekeeper
- H.323 multiple endpoint server
- SIP session border controller
- SIP router
- SIP registration server
- IAX server and client
- IP Telephony server and client
- Call center server
- IVR engine
- Prepaid and postpaid cards system
The software is written in C++ and it supports scripting in various programming languages (such as those supported by the curently implemented embedded PHP and Python interpreters).
Both PHP and Python libraries have been developed and made available in order to ease development of external functionalities for Yate.
Yate is production-ready software.
Yates license is GPL with an exception for linking with OpenH323 and PWlib (licensed under MPL).
Enhancements:
- This release adds support for Jingle (GoogleTalk), XML, and improved PBX support.
- It fixes one minor security bug and several others not security related.

YAMT is Yet Another MP3 Tool which helps you to organize your MP3s. Its a program for GNOME and allows you to edit the ID3 TAG of one MP3 file, change the tag of many files at once and many other.
Main features:
- Editing of single ID3 TAGs
- Rename files based on their ID3 TAGs
- Mass tagging with variables %dir and %file for the current directory and file
- Auto tagging
- Tag exchanging
- Sorting (unsorting) into (from)subdirectories
- Explore your mp3s (with filter ability)
- Create Playlists
Enhancements:
- A log window where YAMTs current activities are shown
- New feature: you may replace eg. ever %20 in filenames with spaces
- Find-feature was restructured and is now named explore
- A popup menu in the edit and explore notebook page (just right-click for it) (If you select an item (eg. mass) the options for this are taken from the appropriate notebook page)
- some documentation (please look at the help menu)
- A progress bar to indicate activity
- "Set" feature renamed to "Auto Tag"
- New option in "Auto Tag": move everything between parantheses to the comment field
- YAMT does not any longer check only for a valid mpeg header since this worked not properly, but also checks for ".mp3" as the extension
- japanese translation
- new logo and icon
- Many bug fixes

Yafumato Web Messenger is a Web-based instant messenger client. Users can connect to supported instant messenger services using only a Web browser via HTTP (or HTTPS).
The Yafumato server connects to the messengers by proxy and provides the Web interface to the user, allowing instant messaging from computers where a desktop client cannot be used.
Yafumato Web Messenger is currently alpha software; as such, it has minimal error handling and is not feature complete.
Enhancements:
- The database is now an optional package; users can now login using messenger credentials rather than single sign-on using the database.
- Messenger session handling has been improved; any active messenger sessions are restored upon signin.
- Unstable messenger sessions can be disconnected and replaced using the new "Reset Messenger" link on the status page.

Yet Another Dungeon-game is a maze (or dungeon) game with a flexible text-based map format and interface plugins.
Installation:
yad/ $ ./configure
yad/ $ make
(as per usual)
Now, to run it --
The environment variable YAD_MODULES needs to point to the full path of interface/.libs in the
root source folder.
For example, I (developer) would use
yad/ $ export YAD_MODULES="/home/dustin/c/yad/interface/.libs"
cd to src, and run ./yad with a map file (currently, neat.map is the test map, neat.map links to woot.map, and vice-versa.)
src/ $ ./yad neat.map
Enhancements:
- The libltdl dependency was removed from the configure script.
