I’ve been using linux at university for quite a while, and it seems much more customisable and better for coding.
So I want to switch to linux from windows 7 at home.
What branch of linux should I use? I’m an emacs user if that gives any insight.
Which desktop enviroment should I use? At uni we use KDE, but it’s too graphical, often I just click on stuff instead of using the terminal. I want one where it encourages me to use terminal more.
and the biggest question, how do I install it all? Should I put everything on external hard drive and wipe my computer completley?
I primarily program in Java and python.
I would recommend that you first try using Linux off Live CD/DVD. Linux Mint, Ubuntu, etc.
Just download and burn .iso onto blank media and boot your computer off of it. Just play around, check various desktop environments, see if all your hardware work with the specific Linux distribution. This step is very useful to decide which distribution you actually want to install onto your computer, especially the latter since, while it has been improving, the biggest obstacle you may face in configuring your computer to run on Linux is often hardware incompatibility. Just make sure everything that you need to work actually works.
If you have no issues wiping out Windows, Linux installation is pretty straightforward these days. It even takes less time in general than re-installing Windows. I would browse the web for an installation note for your specific computer model to see if anyone has already successfully done so, so that you can just follow. That saves a lot of time.
I use Debian (Wheezy now) and KDE. It’s very easy to install and switch desktop environments after installing Linux though, so that shouldn’t be any concern.
