What are some “must have” Ubuntu programs? [closed]

VLC Media Player - the best open source cross platform media player around - plays everything, video/audio files, discs (DVD, CD, VCD), media converter and streamer (the list goes on.....)

Again, so easy to install just install it from the software center.

And... for those using the (dare I say “Best”) Firefox browser, there's even a handy plug in! just install vlc-plugin-* and mozilla-plugin-vlc from the software center.

Ubuntu Tweak - a must have utility for those new users unfamiliar with command line or bash scripts, very similar to the old Windows Tweak UI

Shutter, so that I can provide screenshots to answers in this forum.

Remmina for VNC and RDP connections. Far superior, in my opinion, to the built-in Vinagre.

download/site link for Ubuntu Sofware? One of (if not THE) main reason for switching From Windows to Ubuntu for me is to never, ever again have to "hunt" for software scattered through thousand of websites. Not to mention security concerns (does it have a virus? or a trojan? can you trust the website? is it a legitmate source? is it official?)

99% of my Ubuntu sofware (if not 100%) i got from Ubuntu Sofware Center (or Synaptic). And i cant describe how good it is to have a centralized, trusted, easy to use, software source, where i can browse, find, download, remove, everything from Skype to Eclipse, from Movie Players to Games.

That said, my vote goes for SKYPE

Not open source, i know. But if this contest is windows-users oriented, it surely makes them feel (a bit) more at home. And its a great display of Linux amazing "just-type-in-and-click-install" centralized approach for installing new (and known) software
