vsfplot is a 2D vector and scalar field plotter. It features Line Integral Convolution (LIC) on data, curvilinear scaled arrows following the flow lines, a mixed mode (scalar field map with overlaid vector field), handling of missing data to not interfere with the flow lines, generation of Scalable Vector Graphics (SVG) files (which are easily editable and convertible while preserving the best quality for inclusion in a PDF scientific article), and a color palette designed so the flows are uniformly readable when printed as greyscale.
vsound allows you to record the output of any standard OSS program that uses /dev/dsp without having to modify or recompile the program. It uses the same idea as the esddsp wrapper and preloads a library that intercepts calls to open /dev/dsp and returns a handle to a normal file. It also intercepts IOCTLs on that file handle and logs them to help convert the audio data from its raw form. It then uses sox to convert the raw data to the desired file format.
vt-ng detects virus and worm like activity based on communication patterns. It can be used to detect infected hosts within your internal network and stop the spread of malware. Detection is based on the fact that malware usually tries to initiate many connections to the outside network for various reasons, such as to "phone home", download further malware, or scan the network for other vulnerable hosts.
vtiger CRM is a Web-based customer relationship management (CRM) software. It was developed over SugarCRM (SPL 1.1.2), with sales force automation (SFA) features. It allows sales people to manage their valuable accounts, contacts, and opportunities effectively. It can also be used to track daily tasks, meetings, and email messages smoothly. Installation is hassle-free, and the intuitive user interface enhances the user experience.
vtwatch automatically switches the active virtual console on your Linux system in a loop, acting as a virtual terminal surveillance monitor. The speed at which they switch is configurable, and it is possible to input a search string, which you are notified about if it is found on a console.
vvvP (Virtual Volumes View Photo Edition) catalogs photographs on removable devices and hard disks at the same time. Images can also be arranged in a single virtual filesystem. Each folder of this filesystem can contain images from many disks. The program allows you to view image thumbnails and full images.
