Accepts a container (hash, array, enumerable, your type) and returns a string of option tags. Given a container where the elements respond to first and last (such as a two-element array), the “lasts” serve as option values and the “firsts” as option text. Hashes are turned into this f...

Você já está familiarizado com um casal de classes Ruby (Integer e String ). A classe Array é usada para representar uma coleção de itens. Isso é melhor visto através de um exemplo: $ irb --simple-prompt >> numbers = [ "zero", "one", "two", "three", "four" ] => ["zero", "one", "two", ...
The situation is similar to the one found for Perl in 2003. In 1.8 series of Ruby, we use a deterministic hash function to hash a string. Here the "deterministic" means no other bits of information than the input string itself is involved to generate a hash value. So you can precalcul...

I live in a town dominated by Python, PHP , and Java developers, so hiring someone who can come in and write Ruby code from day one is a challenge. I’ve been thinking about how I learned Ruby myself, how I’ve gone about helping others learn it, and what I would do differently if I had...
