I learnt how to play Cockroach Poker on Friday. I am just jotting down the rules to cement them in my mind, and for reference later.

Eight years ago, I posted a description of an Alphametics Helper. I wasn’t much interested in the answers (as was evidenced by the fact it gave wrong answers, and I only just noticed) so much as the architecture – I wanted to implement a new Puzzle Solving Framework that later proved to be very versatile.

Of course, this is a deterministic procedure, and we can, with diligence, careful calculation, computational power and just a little bit of luck, reverse engineer the algorithm and determine who will be eventually selected.

Progress Bars haven’t progressed much for over a decade.

Let me tell about the Progress Bar component that I will definitely one day develop, with the one proviso: I will probably never develop it.
