I had a lot less variety in my programming month, but still had a lot of fun doing it. In fact, Programming consumed most of my leisure thoughts. More about why I was doing it below, but I’ve been reading Programming Perl as well as skimming through Introducing Go and Learn You A Haskell for Great Good!. Ever since some folks used Haskell during last year’s Advent of Code and this guy’s videos that I mentioned in an early 2021 blog post, I’ve been very curious about the language. In fact, at this point I’ve decided that Go and Haskell will be the next two languages I learn.

Back in 2019, when I did my programming retrospective I made a few predictions. How did those go?

• Work on my Extra Life Donation Tracker? Yup! See below!
• Write more C++ thanks to Arduino? Not so much.
• C# thanks to Unity? Yes, but not in the way I thought. I only did minor work on my game, but I did start a new GameDev.tv class.
• Learning Ruby? Well, I wouldn’t necessarily say I learned Ruby. I did finish the book Ruby Wizardry and I took copious notes. But until I do some practice - maybe via some code katas, I don’t think I’ll have solidified it in my mind.
• 3D Game Dev? Nope, not really.
• Rust and Go? Not even close. Although I did make sure to get some books on the languages.

So, what happened? On the programming front, I wanted to continue my journey to truly master Python after having used it at a surface level for the past 15ish years. I dedicated myself to doing the Python Morsels challenges (more on that below) and working through various Python development exercises. Outside of programming, the time I had off from COVID was used to play with my kids and they wanted to play lots of video games. So we took advantage of having way more time than usual to do that. So a lot of my goals slipped. We’ll get to 2021 predictions at the end, so let’s take a look at 2020!

Python

A user of my Extra Life Donation Tracker program discovered that I had introduced a regression for brand new users who didn’t have a persistent setting. I thought about it overnight and it was exactly what I thought it would be - when I switched away from threading for the GUI, I forgot to add a way to tell participant.py to reload its settings values. I also decided to take a page from a programming podcast I heard recently and change the settings GUI to only have a “Save” button instead of a persistent save button AND a Save button. Especially when I wanted most people to hit persistent save, and that’s not what they’d most likely do by default. So I ended up making 5.2 release to fix both of those issues.

Since I’ve been making a lot of great progress programming with the kids in Scratch, I bought some Circuit Playground Expresses to program with the kids. The Circuit Playground Express can program in Arduino’s C dialect, CircuitPython, or Microsoft MakeCode, which uses blocks like Scratch. Today Scarlett and I made our first useful bit of code, a digital spinner we called The Sibling Chooser. Here’s the code, and you can see that it is indeed like Scratch:
