The Rust + Elm Stack

Harry Goldstein talks with Richard Feldman about the Lean 4 programming language's compile-time metaprogramming capabilities, including how they can be used to control elements of your IDE in realtime. They also discuss other topics like property-based testing, theorem proving, and Smalltalk.You can get ad-free episodes (including video) by supporting Software Unscripted on Patreon! https://www.patreon.com/SoftwareUnscriptedThe Best New Programming Language is a Proof Assistant by Harry Goldstein - https://youtu.be/c5LOYzZx-0c?si=UnTfkczIhdoF7QkxThe Lean Programming Language - https://lean-lang.orgSimon Peyton-Jones: Escape from the ivory tower: the Haskell journey - https://youtu.be/re96UgMk6GQ?si=8xqpAS8VTQaqgbzg"Shen: A Sufficiently Advanced Lisp" by Aditya Siram - https://youtu.be/lMcRBdSdO_U?si=VOwJNeLAvnIRUm_nHypothesis Property-Based Testing library for Python - https://hypothesis.works/ Hosted on Acast.

Mike Bryzek has been a technical cofounder of two very successful companies using some very unorthodox technical strategies that have worked out very well for him and his teams! These include testing in production, spending the first few months of a brand-new company's life investing in automation and tooling before shipping a product, and microservices - but not done in the way I've usually heard them described.Support Software Unscripted on Patreon: https://patreon.com/SoftwareUnscripted Hosted on Acast.
