Why don't you show how to work on variuos OS-es?

I was on that link not long ago :) I think I will stick to MAMP a little while but later I will try to do this manually

I struggle with windows 8 path dependancies, and things not working, and generally things going wrong in a horrible work environment. I also use 3 different laptops/PCs for coding depending on where I am.

This is why I now generally use cloud ides (cloud9/codeanywhere etc) as it gives you a 'fresh' ubunutu environment for every project, as well as a lot of languages / frameworks set up for you - you don't have to battle with OS discrepancies, languages or path routes, and you can switch computers and keep working on the same project without skipping a beat.

I also run a virtual box with linux + atom if I am on one pc for a prolonged time, especially if I need to sort out some horrible file directory structure for a php project close to deployment. Gonna get my head round vagrant and docker as well.

Lots to take in but I knew I had to ditch 30 years of using 100% microsoft OS at some point :)

Most lessons do, I believe show you how to work locally as well.

Sometimes you just gotta go back a little: Like here http://teamtreehouse.com/library/build-a-simple-php-application

The first badge goes over installing PHP on Windows and OSX.

Or, as you'd have to do in a career, read the languages docs and learn to install what you need to install yourself. I also don't use workspaces here unless I'm forking someone else's workspace to help them with their code.
