Beazley's Concurrency From the Ground Up is one of my favorite tech talks ever: In about 45 minutes he builds an async framework using generators, while live coding in an emacs screen that shows only about 20 lines and without syntax highlighting, and not breaking stride with his commentary and engaging with the audience.

It's 8 years old, but definitely worth a watch: https://www.youtube.com/watch?v=MCs5OvhV9S4

Exactly what I thought while watching that video, it's as if he's spitting out the characters as he speaks.:

"A fantastic, entertaining and highly educational talk. It always bothers me that I can't play the piano and talk at the same time (my wife usually asks me things while I'm playing). But David can even type concurrent Python code in Emacs in Allegro vivace speed and talk about it at the same time. An expert in concurrency in every sense of the word. How enviable!"

There's also the one where he live codes a Webassembly interpretor. But my favourite is his talk on lambda calculus. It's incredibly fun to follow through.

Yes, that talk is legendary. Very impressive how he is able to both talk and write the code at the same time.

Is that the one where he modified his interpreter to provide slapstick comedy as part of the talk?

the love of programming and engineering .. this is what motivated me at first place to do CS

Wow - that was awesome - wish I had known of this vid for years - but thank you.

It is entertaining and intelligent, but you won't learn Python from it and you won't get anywhere near a production ready implementation, since it glosses over all the hard parts.

Yes! My favorite Python talk, dude is a wizard

I wish they turned off ads on this. If this is PyCon surely they get PSF sponsorship money anyway...

You can pay YouTube to remove ads and help support content creators as well.

Why? I don't watch YouTube.

Moreover, this video is from PyCon. Which is sponsored by PSF. Which is sponsored by google, meta, AWS etc. So who is pocketing the ad money? Why do I want to pay to support that person? As well as Google and its advertisers?

The logic in your comment is incoherent.
