Ch is an embeddable C/C++ interpreter for cross-platform scripting, shell programming, 2D/3D plotting, numerical computing, and embedded scripting. C/Ch/C++ allow users to use one language, anywhere and everywhere, for any programming tasks. Ch is the solution for:
- Embedded Scripting
- Enterprise
- Academic
- Plotting and Numerical Computing
C++ is C plus plus minus. Ch is C plus (Ch = C+). Ch is a C interpreter. Ch is C with classes and high-level extensions. Ch is a superset of C. Note that C++ is no longer a superset of C. For example, VLA and IEEE floating-point arithmetic in C are not supported in C++.
C is for low-level system programming and embedded systems; C++ for large-scale projects. Ch is optimal for platform-independent scripting in numerical computing and visualization, rapid application development, Web programming and plotting, embedded scripting, shell programming and integration with legacy systems.
Like C++, Ch is designed to be a superset of C, which means a C program can run in Ch without modification. Unlike C++ which is designed for serious professional programmers (elite), Ch is designed for both novice beginners with no computer experience (average Joe and John) as well as experienced programmers.

KSSH is a KDE front-end to ssh.

It can work as a standard KDE application that launches ssh connections in a terminal or as a konsole session.

This means that you can press in any konsole "New Session" and then select "Secure Shell".

INVSTR is a library of C functions that follow the behavior of the standard library string functions, but starting all searches and the like from the end of the string rather than the start.
Enhancements:
This initial release includes the following functions:
- invstrinv
- iwcsinv
- invstrspn
- iwcsspn
- invstrcspn
- iwcscspn
- invstrpbrk
- iwcspbrk
- invstrcpbrk
- iwcscpbrk.

cproto generates function prototypes for functions defined in the specified C source files to the standard output.
The function definitions may be in K&R or ANSI C style, or in lint-library form. cproto can also convert function definitions in the specified files from the K&R style to the ANSI C style.
Enhancements:
- This version was modified to eliminate most of the remaining fixed-buffer limits.

Gnome Crystal project is a light model visualizer for crystal structures.

Gnome-1 version uses Gtk+, Gnome, libglade, gettext, OpenGL(or Mesa) and GtkGLArea.

Gnome-2 version uses standard Gnome-2 libraries and the Gnome Chemistry Utils and its dependencies.

Standard Als PHP Library (SAPL) is a fully object oriented library for Web development with PHP5.
Standard Als PHP Library offers many classes in several packages and is intended to satisfy simple and at the same time recurring needs in Web development.
About PHP:
PHP, short for "PHP: Hypertext Preprocessor", is an open-source, reflective programming language used mainly for developing server-side applications and dynamic web content, and more recently, a broader range of software applications.
PHP allows interaction with a large number of relational database management systems, such as MySQL, Oracle, IBM DB2, Microsoft SQL Server, PostgreSQL and SQLite. PHP runs on most major operating systems, including UNIX, Linux, Windows, and Mac OS X, and can interact with many major web servers. The official PHP website contains very extensive documentation.
There is a command line interface, as well as GUI libraries such as the Gimp Tool Kit (GTK+) and text mode libraries like Ncurses and Newt.
Enhancements:
- A generateClass method was added to the DataBase class.
- The DataBaseColumn class was added.
- getTables and getTableColumns methods were added to the DataBase class.
- The insertTuple method was optimized.
- The toString method was added to the Resource class.
- The fromFile method of the MailAttachment class now takes only one argument, the File.
- Content-Type is now obtained from the extension.
- Content-type methods were added to the File class.
- All W3C 16 color names were added.

pam_bioapi adds BioAPI support to the Linux PAM implementation, the standard for pluggable authentication system for GNU/Linux.

pam_bioapi currently only works for local user authentication (the type that can be performed by login, gdm/kdm/xdm, xscreensaver, su, and sudo).

pam_bioapi has no method of interfacing between a server process and a BSP on a client system. See http://www.bioapi.org/ for more information on the BioAPI standard.

libdaisy library is an engine for parsing Digital Talking Books (DTB) according to the Daisy ANSI/NISO standard Z39.86-2005 and Daisy 2.02.
