An introduction to symbols
Symbols in Ruby are used everywhere and for good reasons. There are two main reasons of using them instead of strings (however they are absolutely not a replacement to strings, more on that later).
A trap to avoid with ruby assignments
When you write something like : my_obj = MyClass.new, the “=” sign does what you think it does. However, when you write : my_obj.yadayada = “123”, it doesn’t (Ruby has a tendency to fool people).
An introduction to hashes
If you’re somewhat familiar with ruby, there are good chances that you won’t learn anything new and exciting in this article. However, if you’re new to the language or just didn’t have time to take a look at ruby hashes yet, maybe you should continue reading.
Oh Ruby, who are you trying to fool?
In every single languages that I know the existence, every arithmetic, bitwise and conditional operators are built-in and global keywords. Well, once again, Ruby had to do things differently. You might be surprised to learn that most ruby operators are not built-in keywords. Fine you’ll tell me… but what are they then?
Is Rails too big?
My 2 triabulle friends and me joined forces to work on a web project. Emile pushed hard and convinced both Dan and me to use cakePHP. My first choice was obviously Rails but still I was happy because it would give me the opportunity to try the PHP MVC framework for the first time. Well, I tried it and liked it. It doesn’t have all the features nor the “polished look” that rails may have, but it does the job very, very well.
Bring your methods to life with punctuation
One of the little things that makes ruby so different is the fact that you can use punctuation in the name of your methods. I could really well be wrong on this, but I think ruby is the only language that allows a programmer to name his method logged? for example. Oh well, I should play it more safe. Let’s say that ruby is the only language I know that allow this.
The one thing with Ruby that won you
Think of all the things in ruby that impressed you when you first start using it and try to remember the one that won your heart. It doesn’t has to be a key concept or a complex principle. A simple twist in the syntax that had you say “Wow… I love this!” could do.
6 reasons why you should try Ruby
I love Ruby. I first learned about it on the Internet several months ago and decided I wanted to give it a try. I was intrigued by the kind of buzz around it. I felt that the Ruby crowd was smaller than the PHP, C# or even python crowd, but those who liked Ruby seemed to like it A LOT.
What's the fuzz about ducktyping?
Even if you’re not new to ruby, the concept of ducktyping might evokes something vague and unclear to you. I personally had to re-read the dedicated section of my ruby book a couple of times before I finally grasped the concept.
An introduction to code blocks
What is a code block anyway? Well, a code block is a chunk of code… that’s all there is to say about it. I know, this part is not really interesting. What IS interesting though, is that you can pass a block to a ruby function and then have this function call the block whenever it wants.
