OSSP uuid is a ISO-C:1999 application programming interface (API) and corresponding command line interface (CLI) for the generation of DCE 1.1, ISO/IEC 11578:1996 and RFC 4122 compliant Universally Unique Identifier (UUID). It supports DCE 1.1 variant UUIDs of version 1 (time and node based), version 3 (name based, MD5), version 4 (random number based) and version 5 (name based, SHA-1). Additional API bindings are provided for the languages ISO-C++:1998, Perl:5 and PHP:4/5. Optional backward compatibility exists for the ISO-C DCE-1.1 and Perl Data::UUID APIs.

Valgrind is a tool to help you find memory-management problems in your programs. When a program is run under Valgrind's supervision, all reads and writes of memory are checked, and calls to malloc/new/free/delete are intercepted. As a result, Valgrind can detect a lot of problems that are otherwise very hard to find/diagnose.
Vamp is an API for C and C++ plugins that process sampled audio data to produce descriptive output (measurements or semantic observations).
The vconfig program configures and adjusts 802.1q VLAN parameters.
Velocity is a Java-based template engine. It permits anyone to use the simple yet powerful template language to reference objects defined in Java code. When Velocity is used for web development, Web designers can work in parallel with Java programmers to develop web sites according to the Model-View-Controller (MVC) model, meaning that web page designers can focus solely on creating a site that looks good, and programmers can focus solely on writing top-notch code. Velocity separates Java code from the web pages, making the web site more maintainable over the long run and providing a viable alternative to Java Server Pages (JSPs) or PHP. Velocity's capabilities reach well beyond the realm of web sites; for example, it can generate SQL and PostScript and XML (see Anakia for more information on XML transformations) from templates. It can be used either as a standalone utility for generating source code and reports, or as an integrated component of other systems. Velocity also provides template services for the Turbine web application framework. Velocity+Turbine provides a template service that will allow web applications to be developed according to a true MVC model.
VIM (VIsual editor iMproved) is an updated and improved version of the vi editor. Vi was the first real screen-based editor for UNIX, and is still very popular. VIM improves on vi by adding new features: multiple windows, multi-level undo, block highlighting and more. VIM-X11 is a version of the VIM editor which will run within the X Window System. If you install this package, you can run VIM as an X application with a full GUI interface and mouse support. Install the vim-X11 package if you'd like to try out a version of vi with graphics and mouse capabilities. You'll also need to install the vim-common package.
