Ruby flew too

Understanding the guts of Ruby Version Management by rolling your own I've been tinkering with a fresh install of Ubuntu 12.10, setting up a nice clean development environment. One of the first things to do, of course, is implement some sort of Ruby version management. RVM and rbenv seem to be the clear winners in this arena, though there are a lot of tools out there that do a similar job . Writing your own version management for your Rubies isn't actually all that difficult. At it's core, we need need two things: A way to segregate the executables of the various versions A way to call the versions at will Segregating versions is trivial - working with files and folders, we can put the various versions into named directories. Actually executing our different versions is not all that difficult either. One way would be to create aliases with version numbers and explicitly call those when we want to use them. The more popular way, however, is to manipulate our PATH ...

I wanted to install Windows 8 so I could play with the metro style app development that I've seen floating around and of course, I like my Linux system for my ruby web development . So - here's the rough steps without a specific walk through of each one, except for reinstalling grub, which is really the crucial step to getting everything to hum and purr along nicely. The caveat is that this worked for me, on my system, it might not work on yours - so take precautions, backup, verify backup, store a backup off-site - you know the drill, I shouldn't need to tell you.: 1) Install Windows 7 Easy enough, follow the prompts and pop Windows 7 on your machine. 2) Install Linux Choose your flavour - I've got Mint up and running, but go for Ubuntu if you prefer. Actually, go for pretty much whate...
