Matt Godbolt Explains "Young Man, It's Robots All The Way Down!"

See Robot Languages - Another Part. Also see Matt Godbolt on Robot Semantic Models of CPUs and the 6502 emulator written in 6502 machine code in Stephen Edwards and Bill Mensch on the History of the 6502 Microprocessor.

Soon Computerphile will be able to interview Davide Sangiorgi and get him to explain how he figured out that business about early and late bisimulation without being driven insane in the process.

Here's Ben Eater showing this on his breadboard 6502 computer

And how the 6522 VIA works as an interrupt controller:

That chip is fairly smart. You could use it to implement a page switching software interrupt and a kind of supervisor more for the 6502. See Talking to Claude about the 6502 Set Overflow pin.

Steven Johnson - So You Think You Know How to Take Derivatives?

A derivative is linearisation, and differential calculus is essentially linear algebra, ...  See  Freya Holmér - Why Can't You Multiply Vectors?  and  Freya Holmér on Continuity of Splines . See also the MIT OCW page:  Matrix Calculus For Machine Learning And Beyond  (Alan Edelman, Steven G. Johnson) Subscribe to The Julia Programming Language . Alan Edelman talking about expressing mathematics as computer code. The idea is that you can use computer languages to communicate mathematical ideas precisely to other people.

Welsh Republic Podcast Talking With Kars Collective on Armenia Azerbaijan Conflict

Image
  In the last 30 hours, Azerbaijan has blocked the Berdzor Corridor (the only route in and out of Artsakh), established a military police presence, threatened to shoot any flying object leaving the capital Stepanakert, and has now cut the gas supply. This is now a blockage. — Kars Collective (Կարսի Կոլեկտիվ) (@KarsCollective) December 13, 2022 Subscribe to Welsh Republic Podcast .
