Software I can’t live without

Here I listed some pretty well-known and some less-known software which I think is great and use on daily basis.

Most of the stuff listed on this page is also free (and open source), so if you like it as well, you might consider the idea about supporting the authors of this great software by buying them a coffee.

KeePass Password Safe - free, open source, light-weight and easy-to-use password manager

Apple fan boys would now probably say that they have 1Password, which offers the similar functionality on their overpriced Macs.

The difference between the two is that KeePass is free and open while you need to pay money for 1Password and you don't even get the access to the source code.

Not to mention the fact, that you can extend KeePass Password Safe functionality with plugins and there are also ports for other operating systems (Linux, Android, Blackberry, J2ME client, iPhone and even Mac OS X).

P.S. Apple fan boys, please don't spam my mail box now with your "Why Mac is better" comments, because most of them are based on your emotionally biased opinion (actually you can try, but it will go straight to /dev/null), thanks.

Virtual Dimension - free, fast, and feature-full virtual desktop manager for Windows platform

The latest version (alpha) was released back in 2006, but it is still the best feature-full virtual desktop manager for Windows platform which works flawlessly even on Windows 7 x64 (tell this to the "new age developers" which have problems with creating the software which works on the latest version of Windows, even tough they started to work on it long after Windows 7 was released).

FileZilla - Open Source (GNU/GPL) FTP client for Windows, Mac OS X and GNU/Linux

In my opinion, the best free FTP client. Just a few weeks ago they have released a version 3.3.0 which adds support for tabs - only feature which was missing so I could call it the best free FTP client.

Redmine - a flexible project management web application

Oh no, now most of you will probably say that Redmine is not even a "real software" (if you are one of those, please tell me your definition of a "real software" and then we can talk).

Anyway, although I think Ruby is for pussies and Python is for real boys (it's a joke so all the Ruby lovers, please don't be offended), this is still a great project management web application with a bright future written using Ruby on Rails framework (it supports integration with many different SCM systems, has many different plugins available for it, etc.).

Thuderbird - Open source cross-platform email and Usenet client based on Mozilla code

Not much to add here - Thunderbird 3 + Lightning extension + Provider for Google Calendar add-on = great combination.

Calibre - E-book management

Calibre is awesome software for managing your e-book library.

It can actually do a lot more then just manage your e-book library (converting between different formats, syncing e-books to your reader device, downloading news from the web and converting it into e-book form, etc.), for the full list of features, check this page.

Oh and the team behind Calibre (Kovid Goyal et al.) is great as well - they are releasing new versions with great new features almost weekly.

Dropbox - secure backup, sync and sharing made easy

While Dropbox is not totally free, they do offer a basic plan with 2 GB of storage for free.

I used Syncplicity before, but I switched to Dropbox, because Syncplicity team didn't care much about their customers.

Syncplicity client had some serious performance issues and was lacking a lot of features but Syncplicity team couldn't care less (if you don't believe me, check their support forums). The Dropbox team on the other hand is great - they are releasing new versions with performance improvements and new features almost on weekly basis.

Note #1: Software is listed in no particular order

Note #2: This is just a short list - I'll probably add more software later on
