I deleted the file, readded it, and once it has the same name, its still unavailable to commit. I tried -f, which then added an empty version of the file to my repository. And the worst apart about that ...

I have been thinking about my shift from Java to Ruby and the thing that strikes me most is Ruby's lucidity ( I know the word lucidity is a qualitative abstract, I guess people who are riding on the same boat will comprehend). Sometimes, I feel I am almost writing psuedo-code. Does Ruby take the paranoia out of programming and make it ...
I want to show a post author's name; <% @post.author.name %> works unless author is nil. So I either use unless @post.author.nil? or add a author_name method that checks for nil as in <% @post.author_name %>. The latter I try to avoid. The problem is that I may need to add/remove words depending on whether there is a value or not. For i...

i have searched around, but can't find any built-in way to do convert an object (of my own creation) to a hash of values, so must needs look elsewhere. my thought was to use .instance_variables, strip the '@' from the front of each variable, and then use the attr_accessor for each to create the hash. what do you guys think? is that th...
Im trying to create a board game generator in ruby which takes images from one pdf and places them them on the tiles of the board-game template pdf. One image per tile.

I want to learn Ruby on Rails. It's my first web language. I understand that Ruby is a language, and Ruby On Rails is a framework. The thing I'm not clear about is whether I need to learn Ruby in depth first, and then learn Rails afterwords. Is that right? Or is it better to learn them simultaneously? And, while you're at it, what's t...
