 ### Differences between MySQL and PostgreSQL
 Unfortunately the story doesn't end there. There are some differences between MySQL and PostgreSQL which further complicate matters. [As this Rails issue thread explains](https://github.com/rails/rails/issues/1515), in Postgres the columns that appear in the FROM clause have to be the same ones that appear in the GROUP BY clause. This is difficult to conceptualise so I'm going to demonstrate with some more SQL.

 On of my goals for 2018 is to learn Go-lang. I've written a few small applications with it but I've never taken the time to learn it in depth. The Little Go Book is a great introduction to Go, it's available for free and it's a quick read. The book covers Go's main features, syntax and principles. It's a great book to give you a solid foundation before going on to tackle more challenging books.
 
 I recommend reading through this book with a laptop. Try typing out each snippet of code and getting it to run. This helps the information sink in and also starts to develop muscle memory with the new programming language.
