It was certainly full of people who are dipping their toes into Ruby. After a quick introduction about Coding Grace and the person the organisation is named after, Grace Hopper, we went straight into writing their first Ruby script.
After some initial setups and wee setbacks from the local Wi-Fi (or lack of), everyone was set up with Ruby set up and exercise files to work on afterwards.
There workshop went pretty swiftly covering numbers, text, variables, Booleans, flow control, arrays, hashes to writing one’s own Ruby piece of code and experimenting by running it.
After running through the slides with everyone trying out scripts in their irb, people grouped up to go through exercises together.

A few things that I noted from the workshop from questions asked:
- tryruby.org: Try out Ruby commands in your browser
- ruby-lang.org/en/documentation: Ruby documentation
- sublimetext.com: Sublime Tex Editor (Recommended)
- Sorting characters in Ruby. Uppercase letters come before lowercase letters.
- http://ruby-doc.org/core-1.9.3/String.html#method-i-3C-3D-3E
- http://www.evc-cit.info/cit020/beginning-programming/chp_07/custom_sort.html
Also how we refer to symbols used in Ruby (and most coding languages)
- [ or ] - Square brackets
- ( or ) - Parenthesis
- { or } - Curly brackets or braces
- ! - Not
Basic command lines:
- ls (Linux) or dir (for windows)- List contents in the directory
- cd name_of_dir - Change directory to name_of_dir
Here’s a handy cheatsheet for *nix commands when you use command line in your chosen terminal/console.
