For me, my favorites were:
0. "Computational Physics, Beyond the Glass" by Sam Ritchie (Strange Loop 2023) - https://www.youtube.com/watch?v=Jv2JgzAl5yU - This guy created an interactive Lisp-based Physics visualizer and got started on it by reading Structure and Interpretation of Classical Mechanics. He now has a full-fledged project, and touches upon many ideas for educating people through innovative means. Really loved this video. Connected the ideas of Logo programming environment and something like a LISP-Physics visualizer.
1. "The Economics of Programming Languages" by Evan Czaplicki (Strange Loop 2023) - https://www.youtube.com/watch?v=XZ3w_jec1v8 - How does creating a new programming language work really? Who are the players, and what goes behind? Very highly recommend this funny, informative talk to understand aspects of creating a programming language other than the theoretical ones.
2. Function Composition in Programming Languages - Conor Hoekstra - CppNorth 2023 - https://www.youtube.com/watch?v=JELcdZLre3s - This is actually about array languages and Haskell and not C++. Encountered "tacit" programming for the first time, and it opened a slightly new way of thinking for me.
And others that I liked were:
0. Ruby on Rails: The Documentary - https://www.youtube.com/watch?v=HDKUEXBF3B4 - Not a Rubbyist, but still liked this documentary.
1. "Software & The Game of Go" by David Nolen (Strange Loop 2023) - https://www.youtube.com/watch?v=n2yJ3FBtU4Y
2. "Making Hard Things Easy" by Julia Evans (Strange Loop 2023) - https://www.youtube.com/watch?v=30YWsGDr8mA - I always liked Evans' written content and zines, as they were fun to read and helped people. It was nice to see how she operates, thinks, and works- that go behind all of these.
