What is your favourite free/open-source software?

[Rosencrantz]

Not everything I'm listing is open-source, but it IS free.

I'm a big fan of:

• Abiword (http://www.abisource.com/) for my writing program
• Irfanview (http://www.irfanview.com/) as my quickie image program since it's great for image viewing and resizing and small fixes and so light weight (I do use photoshop elements for everything else, since I bought it a while ago and as long as I keep deactivating the old copy before I move onto a new computer, I can keep using it)
• BsPlayer (http://www.bsplayer.com/) for videos! I haven't found anything it can't play yet, and it downloads subtitles for me.
  
• NoteTab (http://www.notetab.com/) for html editing. I bought the paid version of this one for spellcheck, but the free is fine
• Calibre (http://calibre-ebook.com/) handling my ereaders, making ebooks, and reading ebooks on my computer.
• Malwarebytes (http://www.malwarebytes.org/) for dealing with malware

I was seeing the posts about openoffice (I'm gonna be trying that out. I've mostly used Googledocs for that so far), but does anyone else have recommendations?

I love Calibre, Mozilla (FF and Thunderbird), 7zip, GeoGebra, some Linux distros (what I've tried so far and liked: Slackware, SlackoPuppy and Mint). Ubuntu has been annyoing lately with trying to become commercial...
I'm trying to replace as much software I can with open-source or freeware. I use Evince in place of Adobe reader and GIMP and Photoshop Elements (which I got for free with tablet) instead of Photoshop. uTorrent was replaced with qBittorrent. CDburner XP makes great replacement for Nero.
CCCP (combined community codec pack ) has everything I need for multimedia purposes, while some people prefer VLC.

As for office stuff, LibreOffice is good for me so far. It's based on OpenOffice.

You will probably find this site very useful, as I have http://alternativeto.net/

VLC media player and CalibRe are great. I like the gimp, too. It has its problems compared to photoshop, but it's not bad for what it's worth and I've had pretty decent results; even when armed with nothing but a computer mouse, no motor skills to speak of, and a vial of unicorn tears.

Ubuntu. Great opensource software system.

OpenOffice has saved my butt many times.

OpenOffice for sure! And I think it's freeware (I didn't pay for it) but it's called Any Video Converter, which is good for converting to .avis I can play on my DVD player (it might be for Mac).

YES! Any Video Converter is great! I used to use it all the time to convert videos for my phone

Thirding this, used it just today to get a video on an mp3 player of all things. There's like no video format that program can't convert to.

Open office and paint.net

Irfanview is a definite for me, and Firefox. Another favourite of mine is CutePDF - it's a PDF creator that works as a "printer", then you save your file where you want. Works with any program that you can print from
