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.

Here’s the key to understanding the original Star Trek.

I wrote a Cryptoquip solver.

My big contribution here is using the “shape” of the words to narrow the choice of clear text letters.

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

Generate more images in this style, including tuning parameters.

As many of you know, I’ve retired. I worked hard, for long years. I deserve a rest. I love spending time with my granchildren, but mostly I’m devoting my time to hobbies.

I thought I’d show you a picture of my hobby room!

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.
