Some awsome programers have made some killer tools for Linux, for free.
Until I deleted my Win2000 partition, I had no idea how much cool stuff is out there.
This page is here to supply links the coolest resources I have found

Vrtualization
With so many soft-pc options available, what does it all mean?
Category Method Disadvantages Examples
Emulation virtulize OS that support arch of hosting system. Low Performance, Low Density VMware, VirtualBox, QEmu, Bochs, Parallels.
Paravirtualization Virtualize modified OS in hypervisor Better performance, needs modified guest OS Xen, UML
OS-level virtualization Multiple iolated execution environments within single operating system. Best Performance, and Density, but guest OSs' share same kerne schroot+dbootstrap, FreeBSD Jail, Solaris Zones/Containers, Linux-VServer, OpenVZ and iVirtuozzo
Desktop Applications
Bochs This project exists as a general virtualization project to maintain common packages, to collect documentation and to give the user a general overview what's available on all Gentoo platforms. Includes: KVM, Qemu, Lguest, Xen, VMWare, VirtualBox, vServer, OpenVZ, Linux Containers, Solaris Zones, FreeBSD Jails. GPL.
QEMU QEMU is a generic and open source machine emulator and virtualizer ( ARM, x86, PowerPC, and S390). GPL
KVM KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). GPL
The Xen® hypervisor for virtualization of x86, x86_64, IA64, ARM, and other CPU architectures. Sites using this include Amazon Web Services, Rackspace Hosting and Linode. GPL.
Linux-VServer provides virtualization for GNU/Linux systems, run on the same kernel, sufficiently isolated to guarantee the required security, with shared resources. GPL.
OpenVZ is container-based virtualization for Linux. OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict.
LXC is the userspace control package for Linux Containers, a lightweight virtual system mechanism sometimes described as ¿chroot on steroids¿.
Virtualbox x86 and AMD64/Intel64 virtualization product, Open Source Software, Oracle owns it now.
Bochs bochs - free vmware replacement.
coLinux coLinux - Cooperative Linux runs on Linux OS in parallel on a Windows machine.
Web Browsers
Thin Mozilla Web Browser Firefox: The Mozilla team hatched "Mozilla, Jr." The name changed from Phoenix -> Firebird -> Firefox due to trademark issues, and Debian had to rename it iceweasel due to more trademark issues, and it looks like it has been renamed again to icecat due to artwork and plugin licences.
Inspite of all the unnesesary legal distractions, the browser has not been killed or killed anyone.
SessionSaver now built-in with:
Edit->Preferences->Main->When Firefox starts:->Show my windows and tabs from last time
Text-to-speach Mozbraille extention for Firefox. This is greate for people who are blind or slow readers. Wish there was an open-source recordings for the blind project"
Opera Web Browser Opera: IE is slick but it crashes like a drunk driver, is as dangerous as a bad girl friend, and is guilty of OS descrimination. Netscape is very cool, but try checking your web page development when your off line, and it hangs. Opera is small, simple, and has just enough window dressing, though the icons could be smaller out of the box.
Google Web Browser Chrome: Nice cross platform, well supported browser by a big search engine and web applicaiton company.
Email Clients (Mail Transfer Agents)
Squirrelmail Squirrelmail: Web mail goes nuts. This is a pretty goood web interface I have run for many years. They seperate layers of client from presentation, but it is hard to find an ajax skin.
Roundcube Roundcube: Web mail with ajax. Has things like drag-n-drop, and right click context. More modern interface. They mix the client and presentation layers.
Evolution Evolution: Wonderful Email user agent. Connects with Exchange for free, as well as IMAP, POP, SIMAP, SPOP, SMTP. Was a product of Ximian, now Novel. Offers virutal folders for special filtering, and a nice GUI.
When you need help with crashes, do 3 things:
1. Get traces with debugging symbols,
2. get E2K_DEBUG traces,
3. Report bugs
Thunderbird Thunderbird: Email user agent. Lite, nice, IMAP, POP, SIMAP, SPOP, SMTP
Sylpheed ClawsMail: Email user agent. Lite, nice, IMAP, POP, SIMAP, SPOP, SMTP, RSS (evolved from Sylpheed).

It has a "utilities," alternate skins, icons, and sounds
and it fully supports xwindidows display export (over ssh).
If you are running SuSE, get licq here.

RSS Reader rssowl: Cool rss reader, for linux, mac, and windows. Uses Mozilla libs for embeded browser."
Text Editor Tools
Komodo Edit Komodo Edit: Free, but not open source. Peforms code checking, offers function argument help, can jump to definitions. I have found it useful for c, python, perl, bash. Does support utf8.
My Favorite Editor Nedit: If you are shopping for a good, small, syntax hilighinging text editor, this is for you. Who needs the bulk or cost of slickedit. Unfortunately, since it is motif based, it does not support utf8.
vi vim: Hay, it's vim. Does a lot if you can learn.
Office Tools: Word processing, printing, spreadsheet, presentations, etc.
Enscrypt Enscript: for pretty command line printing. converts text files to PostScript or to other output languages
LibreOffice

LibreOffice: GPL licensed replacement for Microsoft Office. I have switched to this from OpenOffice.

The FTC (asleep at the wheel again) approved Oracle's purchase of Sun, inheritig all their assets, including open source projects. But Oracle has always chosen the advisarial position to open source, so they made changes and people left to start independent forks (OpenOffice becomes LibreOffice, MySQL becomes MariaDB, Hudson becomes Jenkins, etc, OpenSolaris just died, VirtualBox hasn't forked). Do we learn nothing from a corporation's track record? After the success of LibreOffice, Oracle gave up on OpenOffice, but didn't give it to LibreOffice.org. Insted they gave it to Apache.org. The surface reason was Licensing: Libreoffice uses GPL vs. OpenOffice now uses Apache License.

Deleterious effects of fragmenting a project:
1) splitting developer's efforts slows progress.
2) splitting users community makes support more dificult to find and organize.
3) splitting branding makes public awarness harder, without a unified message.
Oracle does not gain from this, but they make a muddy brown cloud in the community pool anyway.
Oracle's action may not be a "Scorched Earth" strategy, but it is not the most community conscious.

OpenOffice.org OpenOffice: Apache licensed replacement for Microsoft Office, A $400.00 value for free without the bugs from Microsoft! Even exports pdf's, script macros in Ruby, can access real databases. One person's opinion
