Introduction There’s plenty of detailed information about Merkle Trees around and it’s not going to be regurgitated, here. A simple online search will turn up any number of articles with varying levels of detail (and, frankly, quality). As usual, Wikipedia is as good a place to start as any. There’s also a particularly good one by Marc Clifton at The Code Project. Broadly, the problem Merkle ...

The general recommendation knocking around the internet is to download directly from the Godot website, not to deploy the flatpak version or the one in Ubuntu’s software repositories because those are usually out of date (plus ca change).

Last year, we bought our son a Kid’s Kindle Fire for Christmas (although a fake, jolly fat-man that creeps around people’s houses in the middle of the n...

Maybe I’ll think of a project, or something, along the way but, in the meantime, I’ll pick up A Tour of C++ and have at it. I like to make a lot of notes. Concepts in my own words, chapter summaries, links to various...
