Did you know that the Complete ZX Spectrum source code has been uploaded to Internet Archive by Timex. It was written by Nine Tiles on Zilog Development Studio and Timex obtained the same software.
A bit dry but there is a FART joke in there. See the last file.

archive.org/details/time...
The System Variable that controls the CYCLES OF ERROR NOISE has been named FART, later RASP, probably because when his parents took him to see what they had been working on he saw a computer that blew a Raspberry when there was an error. This page contains the Z80 code that dumps the display file to the ZX Printer. The editor shown is the Zilog Development Studio as used by Nine Tiles and Timex Computer Corp. Thanks to engineer Lon Hildreth for making this available. Here are messages such as the dreaded “R: Tape loading error” and also “(c) 1982 Sinclair Research Ltd.” This page of source code documents the INPUT command which inputs from stream 1. It loads the accumulator with 1 and then calls subroutine SELECT. It then clears the lower screen which sets the stream to zero again. Hint: Just swap the two instructions.

Absolutely inhaled both Cal Sounder novels (TITANIUM NOIR and SLEEPER BEACH) by @harkaway.bsky.social over the last couple of weeks. Could not recommend them more. Weird future detective stories where the ultra-rich are also immortal and ten feet tall.

This has to be the nerdiest photo I've ever taken.

Christmas wish list has the desired effect - good haul - no jumpers or socks!

A neat video on recursive/fractal Latin cubes.
Latin cubes have a link to numerical sampling, it seems like these should have some use there too.
