uWiki is a minimalistic wiki engine. All actions are implemented in external scripts. These scripts are wikified, and thus the wiki is extensible by itself. All dynamic access is protected through ACLs. Wiki content and Web content can be mixed in the same directory hierarchy. Markup engines and revision control are plugin-able. Currently, asciidoc as the markup engine and git as the revision control backend are provided. Subdirectories can form independent sub-wikis with own revision control. Features like distributed pages that syncronize between wikis, spam protection, and batch jobs to schedule mirroring of other content (bittorrent, git, rsync, and wget) are in planning.
updateThumbnails stores the thumbnails of photos in a dot directory, stores thumbnails for different applications and sizes, supports XV thumbnails, supports generation of GNOME local thumbnails as used by GQview, only generates thumbnails if the original image has changed, and removes thumbnails where the original file no longer exists.
upnp2mrtg is a simple add-on for the MRTG (Multi Router Traffic Grapher). It can be used to monitor incoming and outgoing bytes of the external interface of the FritzBox DSL router. upnp2mrtg is a command line tool to gather statistics from an upnp enabled FritzBox DSL router. It is a lightweight shell-script for use with MRTG, so no underlying external software (with the exception of netcat) or libraries are required. Using bash-networking instead of netcat is also supported.
vidprofile is a collection of a few components that finds the best way to create MPEG video with mjpegtools. It fully characterizes mpeg2enc from mjpegtools and helps answer the question: given a file size limit, what are the best mpeg2enc options (and values) to use that give the highest possible quality MPEG video? mpeg2enc has an abundance of command line options, and each one tweaks the encoded output (some options tweak to larger degrees than others). vidprofile offers a set of tools to let the user fully test each of the options in mpeg2enc and quantify the output video's size and quality.
vlock is a program to lock one or more sessions on the Linux console. This is especially useful for Linux machines which have multiple users with access to the console. One user may lock his or her session(s) while still allowing other users to use the system on other virtual consoles. If desired, the entire console may be locked and virtual console switching disabled.
vpn-shaper is a dynamic traffic shaper for openvpn, poptop, and similar programs, using iproute2. It allows shaping of traffic between many users conected to one server, and it supports different prioritiy schemes for different users and different types of traffic. Trafic shaping uses the HTB qdisc. Prioritization uses l7-filter and ipp2p and some of the patch-o-matic extensions. Classification of trafic in HTB classes is done by using the IPMARC patch-o-matic extension. vpn-shaper requires the IPMARK patch-o-matic extension, connmark iptables match, and HTB qdisc.
vxref provides integration of the xref tool into vim. The xref tool is a cross referencing and refactoring tool with a free version available that parses C and Java code, and a paid version that parses C++. vxref brings solid auto-completion (as opposed to all sorts of flakey varieties such as omni-complete) and accurate code browsing with scope information to vim.
