I think talking about Clojure at this level shows how distinct and unique the language really is compared to others. Rich has done an excellent job on reviving Lisp for the new era where concurrency and immutable data structures should be fundamentals within the language itself. Targeting the JVM was definitely a smart move on Rich's behalf. It's very rare to see this kind of interoperability. Thank you for the upload.
That explained a *lot* of Clojure concepts very very succinctly. Namely what that community means when they refer to 'persistence' and how that affects time complexity of standard operations. Awesome interview.
This seems to be the most non-abstract Rich Hickey talk on the internet, I did not understand the last bits but I now know that they exist which means that I can work on figuring them out later.
What an enlightening talk! They should make some of these concepts into college material, e.g. designing and implementing a persistent, immutable set datastructure. This really shows where these abstract concepts come together in the real world.
I think you're conflating nerdy discussion and meaningful discussion, lol. I'm just learning clojure and this helped me understand the language in a much more meaningful way than the documentation on the website has so far. I'll give you though, if you're learning or know clojure, you might be a nerd :)
Great stuff! Evolving reference feels indeed like a dual of Observables/Streams. And swap is like scan in streams. Though scan takes the latest value & the state built only in that stream to produce a new value where swap can take any other state too. How would a transaction look like on e.g. 2 observables/streams?
Great to see something other than one-way talks. Thank you, Algorithm. Around 45 min...x86 has a number of compare and exchange instructions, and have retained that terminology for it for many years, as they've added more of them. Windows' library writers probably derived their terms from Intel's hardware level vocabulary.
After you've gotten used to Erlang or Elixir, it's not much of a stretch, and Erlang was definitely an inspiration for Clojure. That'll really change how you think about concurrency and parallelism, being used to more common languages. But, even with the niceties of Elixir, the BEAM (Erlang's runtime/VM) just doesn't lend itself to general purpose programming.
at 50:41, Rich cut Brian off, but Brian's question was about the mutable data structures in Java and .NET. It's unfortunate because Rich response didn't make sense without that qualification where he says "you don't use them"
Im from 2021 and JS is still… await … what??? Resolve that now! What do you mean I’m rejected.. ~shooting in background~ Hello I’m from Microsoft. .NET is coming. And can’t be stopped now. Since Billy the swag Gates is divorced we are concentrating on a younger audience.
I am from 2023! And JavaScript keeps getting more popular despite being bad, but it's ok, Microsoft is slowly taking over the language and ecosystem and fixing the fact that it's not C# by turning it into C#, one TypeScript feature at a time.
2024 - JS and his crossdressing persona TS doesn’t seem to have lost steam at all. There’re even competing runtimes for backend use other than Node - Deno, Bun. The whole ecosystem of its underlying tools are slowly being rewritten in Rust.
