Software Unscripted

Daniel Lemire, creator of simdjson, the fastest JSON parser, discusses parsing performance, benchmarking, and real-world experimentation. They explore multi-threading benefits in parsing, eliminating parsing steps with Captain Proto, iterative development, AVX2 and AVX512 performance impact, handling comments and strings, different parsing approaches, and surprising results with hash maps and index maps in the Rust compiler.

Richard talks with former Rust core team member Ashley Williams, aka ag_dubs,, about various different types of niche domain knowledge - from CSS tricks in web development to low-level systems programming, package managers, and even organization-specific domain knowledge.

Richard talks with HashiCorp cofounder Mitchell Hashimoto about a side project of his: a high-performance terminal emulator that he wrote using Zig and Swift, and which has become his daily driver terminal. Hosted on Acast. See acast.com/privacy for more information.

Richard talks to to Alex Shroyer about his unusually extensive experiences with Array Languages like APL and J - where they come from, how they have more to offer than just extreme conciseness, and what feature creep looks like in a language that's mostly symbols.Links to Alex's website and more info about array languages:alexshroyer.comhttps://nsl.com/https://vector.org.uk/https://github.com/interregna/arraylanguage-companieshttps://tryapl.org/https://bqnpad.mechanize.systems/https://www.arraycast.com/https://aplwiki.com/wiki/APL_Farmhttps://discord.com/invite/yHna7nt7zx Hosted on Acast.

Richard talks with Simon Lydell, a programmer whose open-source JavaScript work ended up contributing to what might be the most infamous package-related outage in programming history. In addition to talking about that story, they also talk about open source in general, breaking changes in general, and specific projects like CoffeeScript, Prettier, Elm, and Roc. Hosted on Acast.

Richard talks to Will Kurt, an AI Engineer at Hex as well as the author of both the countbayesie.com blog as well as the book Get Programming with Haskell, from Manning Publications. They talk about the book, about Haskell in general, and end up comparing Haskell to R, as well as type systems and artificial intelligence! Hosted on Acast.

Richard talks to Ayaz Hafiz about his work on the Roc programming language. They discuss behind-the-scenes compiler details like implementing ad-hoc polymorphism and defunctionalization using lambda sets. Along the way they get into how these implementation details interact with design of the language, and the experience of using the language. Hosted on Acast.

Richard talks to Jakub Konka, a programmer who works on the Zig programming language. They talk about the low-level systems programming involved in Jacob's work on Zig and other projects, including things like disassembling binaries, hot code loading in a systems language, writing a linker from scratch, and testing machine code without access to the actual hardware - or even an emulator!

Richard talks to Chelsea Troy, a programmer working at Mozilla who has a side gig teaching Masters' Computer Science students at the University of Chicago. This is highly unusual, considering she does not have a computer science degree! They talk about how she landed that job, including how the interview process differs from industry interviews, among other topics. Hosted on Acast. See acast.com/privacy for more information.
