wget_img.pl is a Perl script that examines HTML files on the local filesystem, finds all the image tags, and outputs wget commands that would download those images. wget_img.pl is more reliable than wget in finding all the images, and it can force wget to disguise itself to prevent Web servers from denying the automatic download.
Whatsup is a cluster node up/down detection utility. It can quickly calculate and output the up and down nodes of a cluster through one of several possible backend tools and several optional cluster node databases. The currently supported backend tools are Ganglia, Cerebro, and Pingd (which can be downloaded as a subpackage of Whatsup). The curently supported cluster databases are genders, gendersllnl (a locally supported LLNL version of genders), and hostsfile (a textfile list of host names). C and Perl libraries for detecting up/down nodes are also included in the package.
WHDD is a HDD diagnostic and data recovery tool for Linux. It can test a hard drive with reads and writes, while providing intuitive visualization of the process. It also has a function for copying a device, with algorithms optimized for least harm to already-defective source devices. It works with your hard drives at a low level by sending ATA commands, which means that the system doesn't freeze while accessing damaged devices (the device is soft-reset on timeout).
white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.
whitenoise is a small utility that turns your computer into an ambient random noise generator. This can be useful for relaxation, helping you get to sleep, drowning out noisy neighbors, etc. Command-line options allow the user to tweak noise characteristics and set a shutoff timer.
whohas is a command line tool that allows you to query several package collections at once. It currently supports Arch Linux (and AUR), Debian, Fedora, Gentoo, Mandriva, openSUSE, Slackware (and linuxpackages.net), Source Mage Linux, Ubuntu, FreeBSD, NetBSD, OpenBSD, Fink, and MacPorts repositories. whohas was designed to help package maintainers find ebuilds, pkgbuilds, and similar package definitions from other distributions to learn from. However, it can also be used by normal users who want to know which distribution provides certain packages, and which version of a given package is in use in each distribution or in each release of a distribution.
wifiroamd is a background program which tries to just do the right thing to bring up your wireless network. Simple, yet customizable init.d-like scripts are used to determine which networks are preferred and to do things like set the ESSID or WEP keys. Other advanced functionality such as bonding of wired and wireless devices is also automated. wifiroamd is an engine for the handling of connecting to wireless networks. It is entirely command-line based, and meant to run in the background without interaction.
