Ruby Refactoring – part 1

This time I will change Ruby code. My little monster looks like this: def sum_by_column(data) sum_array = data.group_by do |column| [column[0], column[2]] end.values.map { |item| item.transpose[1].inject(:+) } data.group_by do |column| [column[0], column[2]] end.keys.zip(sum_array).map { |first, last| [first[0], last, first[1]] } end If You know what this code does I say: Wow!

CoffeeScript Refactoring – part 1

This will be the first article about refactoring. I love refactoring, so let’s start. I think that the best way to do this is to put some code on the beginning and then change it. Today I would like to show you a piece of CoffeeScript code: if checked_items == all_items $('#myId').prop('checked', true) else $('#myId').prop('checked', false) This code is simple. I check if number of selected items is same as number of all items. And then I select (or not) a checkbox on a web page. As I said it’s simple but can be improved: $('#myId').prop('checked', checked_items == all_items) The...…

Hack4Good

Date: October 29, 2013 Place: Dublin, IE I had the pleasure to be a part of two events in Dublin this week: Hack4good and Web Summit. Today I will focus on the first. What is Hack4good?

It was a competition....…
