I've heard a lot of stuff about RoR for a while, so I decided to finally try it out and see what all the fuss is about.
What is Ruby on Rails? A web framework that runs on the Ruby programming language.
First impressions: too much magic going on. It seems like a good thing for quick development, but I prefer knowing exactly what is going on in case anything goes wrong so the problem can be fixed easily. For this reason, I probably will not use RoR on any on my projects until I understand more about it.
Things I liked about RoR: the ActiveRecord ORM, and the built-in REST support. I also liked that it is very easy to deploy once you know what you're doing.
I had heard of SCSS, but I had never used it. It's very enjoyable to use, since you can nest CSS definitions, and it has some neat features that make it a lot easier to maintain stylesheets, such as variables and functions.
When learning a new framework, I try to follow the official tutorial, but tweaking the steps a bit in order to create a different application.
To learn RoR, I decided to make a small contacts application, where you can add contacts to a list and edit/delete them. It's on a repo at Github, in case you wanna take a look.
Now I'm also learning Django (a python web framework), and everything seems a lot less magical, so I will probably use it instead of RoR. Both of them seem to solve the same problem (CRUD apps).
