Rails Generating & Scaffolding

Rails' use of strict naming conventions means a lot of core code SHOULD be in the same format whoever writes it? It could be written by a friend, colleague or a computer... it shouldn't matter because the same Rails rules apply to everyone.

This means that Rails can actually do some tasks for you! It can actually build things and write code on your behalf...

Coming from another language like PHP, this can seem like magic.

RVM to rbenv

Why? @sstephenson explains it best here.

---

1) remove RVM from your system

This should get rid of the rvm dir and any installed rubies:

$ rvm implode
