Eclipse – http://www.eclipse.org/
Eclipse is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the lifecycle. It’s quite hardcore in my personal opinion so certainly not one for beginners.
NetBeans – http://www.netbeans.org/
All the tools software developers need to create cross-platform Java desktop, enterprise and web applications. Runs on Windows, Linux, MacOS, as well as Solaris. I never got on well with NetBeans but it is a good application, just not one I choose.

While not strictly free, once your trial period expires only a subset of the functionality gets turned off. The really useful bits such as code compete, syntax suggestion and its own SVN client remain fully operational. In reality the only stuff I’ve found frustrating is that the rename functionality is removed unless you buy the license. Alternatively you could obtain Zend certification and in turn receive a free license – your call.
Ubuntu – http://www.ubuntu.com
The most popular Linux distro at the moment – offering astonishing performance, usability and support (from a massive online community) all for free.
PCLinuxOS – http://www.pclinuxos.com/
One of my favourite Linux releases; PCLinuxOS is very different to Ubuntu but powerful and usable in equal measures. I find it a lot more intuitive but purely though personal preference. It too is supported by a healthy community.
Fedora – http://fedoraproject.org/
I’m not a Fedora user but there are an awful lot of them. Fedora was the daddy long before Ubuntu appeared on the scene and therefore it inherits a lot of excellent features from how long these guys have been doing it. Excellent software, strong communities and worth a look. This is Linux too incase you didn’t know.
openSUSE – http://www.opensuse.org/
Quoted as being one of the more fully featured, usable editions of Linux – openSUSE has a lot of users and is one of the major players in the scene today.

VLC Media Player – http://www.videolan.org/vlc/
A very popular application; a highly portable multimedia player for various audio and video formats. It will play just about anything too.
VirtualDub – http://www.virtualdub.org/
It’s a bit like a really cut down, free version of Adobe Premier… VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images. Worth a look.
Youtube – http://www.youtube.com
Youtube is maybe an odd choice to put into the video playback area but there’s a good reason for it. You can upload your videos to Youtube quite happily for free and there are hundreds upon thousands of hours of footage on there. From the illegal to the completely random Youtube has more video playback options than your wildest dreams.
CamStudio – http://camstudio.org/
This is actually a screencasting utility so it doesn’t really fit into this category very well… CamStudio is able to record all screen and audio activity on your computer and create industry-standard AVI video files and using its built-in SWF Producer can turn those AVIs into lean, mean, bandwidth-friendly Streaming Flash videos (SWFs).

iTunes – http://www.apple.com/itunes/download/
iTunes is one of the world’s most popular audio applications, although it breaks through that label by allowing users to purchase media online, schedule podcasts, view artist information etc. Very popular.
Winamp – http://www.winamp.com
While not open source, it is free and very good indeed. Far better than iTunes in my personal opinion.
MusikCube – http://www.musikcube.com/
Another iTunes alternative – very good, just really a matter of personal taste in the end.
Amarok – http://amarok.kde.org/
This is one of the best media players I have ever encountered, unfortunately it’s purely limited to Linux (KDE environments only) so it’s beyond the reach of Windows users and the “Ubuntu mainstream”. It’s amazing though and I highly recommend it.
Foobar2k – http://www.foobar2000.org
Foobar2000 is an advanced audio player for the Windows platform. Some of the basic features include full unicode support, ReplayGain support and native support for several popular audio formats.

A free antivirus application (although it doesn’t detect spyware). It apparently has one of the best detection rates out of the free antiviruses on offer.
Clamwin – http://www.clamwin.com/
A free antivirus with a high detection rate for infected files. It’s not very invasive because it doesn’t do on-access virus scanning – you specifically need to say which folders to scan. This is both good and bad – good if you’re IT savvy because you don’t need on access scanning because you’re not stupid enough to do “dodgy” things unprotected. It’s bad if you’re not because it won’t tell you that there’s a problem until you tell it to look.
Comodo Firewall – http://www.comodo.com/products/free_products.html
Comodo Firewall, rated by PC Magazine Online as an Editor’s Choice, constantly monitors and defends your PC from internet attacks. It’s easy to install and use and passes the industry’s most stringent firewall “leak” tests.

Windows Defender is a free program that helps protect your computer against pop-ups, slow performance, and security threats caused by spyware and other unwanted software. It features Real-Time Protection, a monitoring system that recommends actions against spyware when it’s detected and minimizes interruptions and helps you stay productive. It’s Microsoft though, but good enough I suppose. Not my sort of thing but a lot of people use it.
Spyware Terminator – http://www.spywareterminator.com/
Does exactly what it says on the tin. Spyware gets terminated. End of.
Arovax Antispyware – http://www.arovaxantispyware.com/

Azureus – http://azureus.sourceforge.net/
One of the most popular torrent clients available, this Java built monster does the job very well. My gripe with it is that it munches it’s way through your RAM at an alarming rate (being a Java application). Good though, just a bit hungry for machines are left online 24/7/365 like mine is.
Flashget – http://www.flashget.com/en/download.htm

LogMeIn – https://secure.logmein.com/home.asp?lang=en
Their website states “20 million users trust LogMeIn solutions for remote support, access & backup” so that probably says enough.
Putty – http://www.chiark.greenend.org.uk/~sgtatham/putty/
I wasn’t quite sure where to put Putty but I was certain that it needed to be in this list – I use it on a daily basis for remoting into servers, connecting to MySQL databases etc… It’s simple and a vital application.
CDBurnerXP – http://cdburnerxp.se/
This is an amazingly useful, free burner application. Although I don’t believe it works on Vista yet…
AutoHotKey – http://www.autohotkey.com/
AutoHotkey is a free, open-source utility for Windows. With it, you can automate almost anything by sending keystrokes and mouse clicks. You can write a mouse or keyboard macro by hand or use the macro recorder. It’s a very useful application and worth a look – especially good for those with limited finger dexterity – because it can automate short-hand typing into long-hand (if set up correctly).
Visuwords – http://www.visuwords.com/
This isn’t an installable application but rather a very cool online dictionary/thesaurus. You enter a word and it graphically models that word, with various uses and synonyms mapped around it like a mind-map. A very cool free “service” for writers.
Notepad2 – http://www.flos-freeware.ch/notepad2.html
It’s basically notepad but more helpful for doing code and stuff in. It’s just notepad with more functionality; which makes life a bit easier. Code highlighting is handy and it doesn’t need installing and it doesn’t touch your registry. It’s safe, simple and very useful.

The search is adaptive, so Quicksilver will recognize which items you are searching for based on previous experience.
