I was browsing around on the Khan Academy website looking for some coding courses to do in the holidays. It was recently the “hour of code” challenge and Khan Academy has a number of free online courses. For those unfamiliar with the concept, the “Hour of code” is designed to introduce computer science to students during Computer Science Education week in the U.S. It is organised by the Code.org organisation in Seattle, and it is a movement that has spread around the world. My friends Michael & Chris will also be the first to tell you that SQL is not coding. Nevertheless, the Khan Academy course was a fun introduction for me to learn SQL.
