  • Learning Without Doing

    I am back on the learning Scala trail and it is clear that just reading books and articles or watching videos won’t cut it. It needs to be hands-on coding. This article highlights that some skills cannot be learnt without actual doing. Links Learning without doing

  • Scala + Docker quickly

    I am currently starting to learn Scala (to add to a myriad of other languages I have programmed in over my career). We are also in the process of “dockerizing” our application. So I wanted to try for myself getting a simple Scala application running in Docker. This page has a very simple guide to getting a “Hello World” application up and running.

  • Simple Change = Big Impact

    A simple change in message can lead to a big impact. Without changing the price of the drink, the University of Winchester reduced the number of disposal cups used in a year by 34K. This was achieved by saying there was a “25p penalty” for using a disposable cup rather than a “25p discount” for using a reusable one. Links Plastic coffee cup waste is being cut by a simple change
