2016 is almost over and NOW I touched HTML5 Canvas!
Today I was playing (never competing, please!) on a CodeChef programming contest and was dismayed when comparing my timings with some other competitors. Theirs were way shorter and I saw no way to improve my O(N) solution because I HAD to read an array of values. My processing was taking place while reading the data, using no loops only simple calculations.
If you are seeing this it means the upgrade (mostly) worked!
When creating a simple web application for a friend I found out the Formtastic (later Simple Form) solution for a
belongs_to: :customer associaton, a <SELECT> was not the best. It simply loaded all customer names and ids into the HTML (more than 15 thousand!). Among the solutions I thought an Autocomplete field to be the best.
A recurring issue I have when creating new Linux VMs under VirtualBox is to make the Guest Additions to work.
