Linux Application List
This list contains my preferred applications.  I include links for every application but you should use your distributions package where possible.
I have a few requirements for applications:
1) They must be truly Open and Free.
2) I prefer GTK over QT apps

 I am aware that this is very subjective, if you want to convince me that your preferred app is better email me at:

Email:
Evolution: I recently switched to Evolution and was impressed with it.  It is a lot heavier than Thunderbird but it's extensive support of filters and search folders helps me keep my large mailbox in check.  http://www.gnome.org/projects/evolution/
Thunderbird: I used Thunderbird for a long time and only recently switched.   If all you need is a mail client then Thunderbird is the best out there with great spam filtering.  http://www.mozilla.com/thunderbird
Usenet:
Pan: The latest version of the Pan Beta's have all the features you may need in a Newsreader.   See http://pan.rebelbase.com/downloads for the latest beta.
        LottaNZB: LottaNZB is a GUI for Hallanzb, one of the most powerful NZB clients available. See: http://www.lottanzb.org/ for the latest release.

SSH Applications:
Putty: A cross platform SSH Client.  http://www.chiark.greenend.org.uk/~sgtatham/putty/
GSTM: A great application to manage all your SSH Tunnels.  http://gstm.sourceforge.net   (Site seems to be dead)
HotSSH: Looks like an interesting project, has not released anything yet.   http://www.gnome.org/projects/hotssh/

Bittorrent:
Azureus: The most feature rich Bittorrent client available for any platform.   The largest complaint against it is the sometimes heavy memory usage.  http://azureus.sourceforge.net/
        Deluge: The latest version of Deluge should meet all but the heaviest downloaders needs http://deluge-torrent.org/
        Transmission:  Transmission is another decent client, it is cross platform with a clean interface.  http://transmission.m0k.org

Disk Recording:
Brasero:  The best Gnome Disk recording application, the latest 0.8 release almost matches most of the major features of K3B.  http://www.gnome.org/projects/brasero/

Office Applications:
OpenOffice:  Full featured office suite that is compatible with MS Office.   http://openoffice.org

Instant Messaging:
Pidgin (Formally GAIM):  I don't use instant messaging except at work via sametime (Pidgin with the meanwhile plugin) but Pidgin seems to have all the features needed in an instant messaging client.   http://www.pidgin.im/

FTP/SCP:
GFTP:  Easy to use two-paned FTP/SCP client.  http://gftp.seul.org/
FileZilla: There is now a port of the popular Windows FTP/SFTP client it is a little rough right now but usable.  http://filezilla.sourceforge.net/
Nautilus:  You can also open FTP/SFTP/SSH connections in nautilus by typing ssh://location or  ftp://location in the location bar.

Network Connection manager:
Network-Manager: Tool to manage wired and wireless network connections.  "Linux Networking made Easy".   The latest version will support dial and Cellular devices.   http://www.gnome.org/projects/NetworkManager/
WICD: A connection manager written in Python that supports WPA, WEP, and a number of EAP types.  http://wicd.sourceforge.net/

Web Design:
NVU: Easy to use WYSIWG web authoring tool.  http://www.nvu.com/
Kompozer:  This is an unofficial update to NVU that fixes a number of bugs.  http://www.kompozer.net/
Bluefish:  "Bluefish is a powerful editor targeted towards programmers and webdesigners"  http://bluefish.openoffice.nl/

Video Player:
Totem: In the past I used Totem with the xine back-end but Gstreamer has come along way and is now my default media player.  Mplayer and VLC are also great media players but neither support Gnome-vfs so they won't open videos across any of the Gnome network locations.   http://www.gnome.org/projects/totem/

Video editing:
AVIDEMUX: Easy to use video editing solution.  It is probably pretty basic but it suites my needs.  Pitivi looks nice as well.  http://avidemux.org/

Audio Player:
Banshee:  Rhythmbox does a great job but Banshee reminds me of a streamlined iTunes.  http://banshee-project.org/Main_Page
Rhythmbox:  The new Banshee is great, but I have grown to love Rythmbox once I got my Shuffle working with it.   http://www.gnome.org/projects/rhythmbox/

DVD Video Creation:

Tovid GUI: http://tovid.org/
Devede:  http://www.rastersoft.com/programas/devede.html


DVD Copying:

XDVDShrink: http://dvdshrink.sourceforge.net/
DVD95: http://dvd95.sourceforge.net/

DVD Rip:
       Thoggen:  
Thoggen only rips to ogg but that suits me. http://thoggen.net/
DVD::RIP:   DVD::RIP is a DVD ripper written in pearl.   The interface is a bit unintuitive but it will rip almost anything to almost any format.   http://www.exit1.org/dvdrip/
OGMRip:  A great easy to use DVD Ripper, it has replaced Thoggen has my favorite tool for this.

Image Editing:

The Gimp: In the past I never edited photos but now that we have a child we have a ton of photos and many need to be cleaned up, GIMP has never failed me.   http://www.gimp.org/

Image handling and Organizing:
Gthumb: GThumb's simple interface suits my needs perfectly, F-Spot is another option.  http://gthumb.sourceforge.net/

ISO Editing:
        ISOMaster: Utility to modify disk images (ISO's). http://littlesvr.ca/isomaster/

Par2 Application:
GPar2: GTK Front-end to Par2.  http://parchive.sourceforge.net

Password Manager:
Revelation+Applet:  Revelation is a GTK application to securely store passwords.  http://oss.codepoet.no/revelation/
KeepassX:  A QT GUI for the popular Keepass application.   This and Virtualbox are the only QT applications I use daily.  http://keepassx.sourceforge.net/

Virtualization:
Virtualbox:  Innotek's VirtualBox is a GPL licensed host for virtual machines.  Not all features are available in the GPL release but it works well and is very stable.  Supports the Virtualization extensions in modern AMD and Intel CPU's. http://www.virtualbox.org/
KVM:  
"Kernel based Virtual Machine", available since 2.6.20.  Supports the Virtualization extensions in modern AMD and Intel CPU's.  Uses a modified QEMU as the front-end. Works well however there are yet to be any great GUI's for using it.  This isn't a big deal but for some the lack of a nice GUI will be a problem. http://kvm.qumranet.com/kvmwiki
QEMU:  The granddaddy of Linux Software virtualization applications; it is stable and has a number of great GUI's available.  Now that kqemu is open source it runs well on systems that don't supports the Virtualization extensions.  If you have an older CPU and want to run another OS in a VM then QEMU is your best bet.   http://fabrice.bellard.free.fr/qemu/

VOIP:
Ekiga:  Nice simple SIP softphone that is integrated with Gnome.  It works flawlessly with my Viatalk service.   I know many prefer Skype but I hate that Skype is proprietary and the poor voice quality.   With a SIP phone like Ekiga I never worry that someone else is using my bandwidth.   KDE users should take a look at OpenWengo.   http://ekiga.org/
