The next time you use any navigation device, software or Google Maps thank Dr. Gladys West. Her contributions to the mathematical modeling of the shape of Earth, and her work on the development of the satellite models that were eventually incorporated into  the Global Positioning System (GPS) technology. #BlackMastodon #BlackHistoryMonth
If you want to learn path tracing and render images like this, but have been put off by the math, check out this 3 part blog post on casual path tracing in shadertoy. It is very light on math but still allows you to render some very impressive images.

Here's the other video I made. This explains how to turn a directed acyclical graph into a flat list of actions using topological sorting.

I once took a stab at making youtube videos. I might make more someday dunno.
Here is one on search algorithms. There's a good chance there are 2 algorithms here you haven't heard of imo!

Everyone on mastodon: No like! Boost!
Me: *boosts*
Mastodon: *crickets*
Me: you want me to boost then feed my reward center by showing me the boost was appreciated!
Mastodon: No. You boost. You be happy. You be quiet.
Me: *likes* 😝

Looks like the answer is that the 68000 did a 16-bit add in one clock just fine. But it takes a clock each for:
-Decode instruction
-Fetch data from RF
-Do add
-Store data back to RF.

...at least I think so. The internals are surprisingly poorly-documented given the age and ubiquity of the machine!

I did find this though:

A zoomable picture of the whole 68000 down to the transistor/diode level. Amazing!

The best way to find every AA battery in your home is to need a pair of AAAs.

what i miss here about RTs isn't the dunking, it's having a handy format for saying "what this person tooted about is the thought i'm jumping off of". which is like...idk, i'm a big fan of intertextuality, and RTs create linked-but-not-the-same thoughts, and that is very helpful for me.
