Once upon a time, I wrote a reasonably-strict-C89 C language program that “relocates” a function in memory and then runs it. That relocated function can relocate itself again, and run that copy, and so on and so forth.

I was curious about whether the “hint” that you get with an official Cryptoquip makes any difference.

I was also curious about how hard it is to construct a decent Cryptoquip.

I wrote a program that generates images in the style of Piet Mondrian:

Generate more images in this style, including tuning parameters.

I wrote a program to help solve Jumble word puzzles.

I wrote a Z80 assembly program for my RC2014 Zed computer. I wanted to get a complete CP/M experience, so I used the CP/M 2.2 ASM assembler, LOAD relocator, and the DDT debugger.

I did cheat a little. Although I used the vintage RED editor for some text input, I also wrote some on my Linux laptop, and transferred to the RC2014 Zed via XMODEM.

I’m a little happier with my wordle-solving regular expression today.

I heartily endorse Wordle as a word game.

I didn’t do great on Sunday, August 28 2022 Wordle:

The Go programming language has a unique, built-in concurrency model that can make some processing much easier.

Have one goroutine do some (probably recursive) work. It puts results on a channel. The main goroutine reads results from the channel and possibly does some filtering on those results, like output unique values.
