now might be a good time to plug the talk i gave last month about the AT Protocol. it’s about the relationship between the user and the product, about the shape of the web, and a bit about death

Still wrestling with generic tools for your dev workflow? It's time to build your own.
In this talk from our AI Meetup, @raf.dev shows you how to create custom, AI-powered tools like a personal slide generator with React and an AI dev notebook with Astro ➡️ youtu.be/MWGeGtIhf7o?...

Back to NES debugging. I have a 100% repeatable crash, the PC has got out of step with the code and has started executing invalid opcodes. How the PC called the wrong addess is the mystery. ROM bankswitching could be behind the problem, or the address being called is just wrong! Callstack will help!

added callstack tracking to probes. when you add a probe to a function call (eg the fib calls below), selecting the value highlights (in dark purple) values resulting from that immediate call, and (in light purple) values resulting from subsequent calls

-- Bleh, we should be using 'GHC.Internal.Stack.callStack' instead of
