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! I wrote this code but it’s terrible. I must do something with it. OK, lets start from the beginning. This method gets data as an array of integer arrays. Like this: [[1, 2, 3], [4, 5, 6]]. Then groups the data by first and last column and sums by...…

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...…

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’s one day of coding in good cause. Programmers from different countries come to one place (this time in Dublin) and create applications for community. For example: How to give homeless people food to survive? How to fulfill the dreams of dying children? How to follow people carrier path after graduation? and many, many more. How did it looked like? It was a competition....…
