Although we all have our favourite Linux distributions, and mine is most definitely Ubuntu, it is often the case that in the workplace we have to learn another distribution, and while that is still Linux is may operate in a way that is quite different to what we are used to. A common workplace Linux distribution is RedHat Enterprise Linux which is supplied complete with a support package. The problem here is that if you want to install it to just learn about it, the price tag might put you off (it currently starts at $349). There is a related free version called Fedora, but this has a slightly different focus, where RedHat goes for stability over features, Fedora is more cutting edge. The result is that the two may not be the same, and depending on what you want to do, Fedora might not provide you with the knowledge you need to work with the RedHat environment. Help is at hand though, RedHat provide the source code to their distribution, which, thanks to open source licensing can be reused.
