Discovering Crystal

I was working with Ruby on Rails on a project with other very skilled Ruby and Rails developers. As many others working with Ruby, we liked it’s syntax, it’s ease of use, it’s dependencies (gems) but had some issues with it. Every programming language does. As luck would have it, I was also in close contact with some very vociferous advocate of Crystal. You can imagine, with the tagline: “Fast as C, Slick as Ruby”, I was hooked. #xpost

Deckchecks, Heuristics, and Decision Trees

One of the tools judges employ to thwart attempts to cheat is to require players to write down what cards they will be playing within a particular tournament, and routinely check them. Judges must perform these checks the fastest way possible to not delay the tournament. As such, they developed a myriad of techniques. I feel we under-use the availability of the decklist, so having a clear plan ahead of actually getting the deck in our hands can prove highly effective. In this post, I would like to explore some techniques' inner workings. Propose a hypothesis on why they might work in some situations but not others. Consider unexplored alternatives. And build a heuristic on what method is better for each circumstance. Join me! #mtg
