Free interface library software for linux

The goal of the General Applet Interface Library is to give programmers a simple yet powerful applet interface. This library supports wmapplet/dockapps, GNOME 2 panel applets, and ROX panel applets.
This library supports at the moment Dockapps, Gnome 2 Panel Applets and Rox panel applets. In the future support for XFCE 4 and KDE is planned to be added. The applet program doesnt have to care about if the applet will be used on the Gnome panel or in the dock. The library handles that.
Over 50% of the code in a Dockapp and a Gnome 2 Panel applet does actully only one thing, setting up the applet window. With GAI, you can reduce it to just a few lines of code.
Enhancements:
- Updated the example applets.
- The preference dialog is now nicely resized.
- Fixed some minor memory leaks in the preference dialog.
- API change: The function connected to gai_signal_on_preferences() shall now take: (gboolean changed, gpointer data) as argument. changed is true if the user changed
- anything in the preference window. False if the user did nothing.
- Added two new preference window items. GAI_LISTSTORE and GAI_EDITLISTSTORE. The first shows just a list, no altering is possible. The second provide a list that can be increased and reduced by the user. (NOT YET FINISHED!)
- Cleaned up parts of the preference generator. Several minor memory leaks fixed.
- Update gai.spec. Some Fedora Core changes by Michael Schwendt mschwendt@users.sf.net, and Michel Alexandre Salim salimma@users.sf.net
- Allowing applet to be bigger than 1000 pixels (2560 is now max).
- Ashley V wants to have Shermans
- aquarium real big Destroying (clicking on the window manager "X" icon) the preference window now works fine.
- Destroying About box is now handled correctly.
- Rewrote large part of the right mouse click menu handleling code. Now you can remove, change, insert and add menu items during run time. gai_menu_insert(...), gai_menu_change(...) and gai_menu_remove(...) is new. gai_menu_add now returns an integer that is the ID of the menu item.
- Fixed broken libdir link in gai.pc
- Make sure GdkColor is never null when given to applet.
- Documentation updates.
- Various minor fixes found on the fedora extras by Michael Schwendt and Thorsten Leemhuis fedora@leemhuis.info. Please mail me fixes directly!!
- GtkFileChooser dialog is now used instead of GtkFileSelector when GTK+ 2.4 or later is detected.
- If gtk+ 2.4 or later, use varously updated widgets instead of older ones.
- Merged big nls patch by Olaf Leidinger Thanks!
- NLS is finally supported for GAI. Not yet there for applets
- The BonoboUIVerb array canary was missing and that caused the GNOME to crash. Patch by Jean-Yves Lefort

Fid Core Library is the core library for the Frigand Imperial Desktop, a genuine Unix desktop environment based around multiprocessing, text-stream IPC, and the "everything is a file" concept.
It supports Emacs-like extensibility, customizability, and built-in multi-buffer support.
Enhancements:
- This release adds testing support for the axioms over buffer implementations and user interfaces, a better implementation of interactive, and a new cursor movement mechanism that allows the user interface to manage point itself (and, hence, keep it always on a widget).

MAT Template Library is a C++ mathematical template class library. The library contains classes and routines for working with:

matrices
vectors
finding roots of polynomials
solving equations
and more...

The GTK ADI Library is a GTK widget library that implements an ADI widget framework.

GTK ADI Library is an Advanced Document Interface: yet another approach to the MDI - Multi Document Interface.

conexus is a generalized C++ I/O library that includes support for BSD sockets, serial/TTY, and packet capture (via pcap).

conexus library utilizes sigc++ for object communication. A companion library, conexusgtk, provides a set of gtkmm widgets.

dnAnalytics Numerical Library is a numerical library for the .NET Framework. The library is written in C# and is available as a fully managed library, but also provides an interface to native BLAS and LAPACK libraries.
dnAnalytics Numerical Library is compatible with Mono and has been tested on Windows, and various Linux distributions. The current release includes matrix, vector and complex number classes, and support for basic linear algebra routines (such as LU, Cholesky, QR, Levinson, and SVD).
We will be adding optimization, calculus, random number, statistical, option pricing, genetic programming, and neural network components in the future.
Main features:
- Fully managed mode.
- Optional support for the native numerical libraries:
- Intel Math Kernel Library (MKL)
- AMD Core Math Library (ACML)
- ATLAS and CLAPACK
- Support for sparse matrices and vectors.
- Dense and sparse solvers.
- QR, LU, SVD, Cholesky, Levinson, and Symmetric Levinson decomposition classes.
- Matrix IO classes that read and write matrices form/to Matrix Market and delimited files.
- Complex and "special" math routines.
- Overload mathematical operators to simplify complex expressions.
- Runs under Microsoft Windows and Linux.
- Works with Mono.

XML-RPC Client/Server C Library is a cross-platform software written in C that supports persistent HTTP/1.1 conenctions over SSL and comes with XML-RPC interface description language and client/server code compiler. Libxr depends on glib2 and libxml2.
Main features:
- Persistent connections over HTTP/1.1
- SSLv3/TLSv1 using OpenSSL.
- XML-RPC interface description language (XDL).
- XML-RPC client stubs/servlet skels compiler.
- Multiple servlets per server.
- Servlet lifetime (init -- call -- call -- fini).
- Multiplatform (linux, mingw32 on windows).
- IPV6 as soon as OpenSSL 0.9.9 is released.

NetSieben SSH Library is a Secure Shell client software written in C++. NetSieben SSH Library utilizes Botan library for its cryptographic functions, allowing for a large choice of algorithms to be used in SSH communications.
As a developer you may wish to integrate SSH client functionality into your applications. You can now use the NetSiebens API, instead of spending countless hours developing your own solution.
The SSH library was created by the NetSieben developers who, after researching the limited number of options available to them from both commercial and open source communities, found these solutions limited and at best, still in early stages of development.
Enhancements:
- A fix for an error logging issue seen during authentication, more detailed authentication error messages, an easier error reporting interface, fixes for some debugging issues in the Windows port, and new code examples that reflect the changes to the error reporting interface.
