Ron Pressler's Curry On 2015 talk arguing that imperative languages should not be polluted with pure functional concepts like monads. He favors simple blocking code over non-blocking styles.

Scott Wlaschin's NDC Oslo talk on four 1970s languages, SQL, Prolog, ML and Smalltalk. It explains their philosophies and what practical principles they still offer modern developers.

Guy Steele's invited talk at Clojure/conj on the informal metanotation computer scientists use in papers to describe languages. He traces how this notation developed and why it is often unspecified and arcane.

A two-hour live stream in which Aaron Hsu explains the architecture, design history and aesthetic of Co-dfns, his parallel APL compiler. He walks through the code and the reasoning behind its dense style.

A 2007 Google Tech Talk in which Cliff Click of Azul Systems presents a lock-free concurrent hash table that scales to 768 CPUs. He explains why it is correct by reasoning in a different way than usual happens-before and memory-order arguments.

Peter Alvaro's Strange Loop 2015 talk argues that query languages let you state what you mean, and applies that to distributed programming. It covers Datalog, Dedalus and the Bloom lineage for reasoning about distributed systems.

Aaron Hsu discusses design patterns and anti-patterns in APL and why the language is productive despite its write-only reputation. He argues that idioms matter more than libraries in array languages.

Jon Purdy's Stanford EE380 seminar giving an overview of concatenative programming, from function composition theory and history down to low-level implementation and correctness benefits.

Nada Amin's Strange Loop talk on programming languages that build on themselves, centered on towers of interpreters and nestable interpretation in Scheme. She shows how interpreters can be stacked and collapsed.

Alan Kay argues for rethinking how computer science is taught in schools, drawing on his work on object-oriented programming and GUIs. He discusses how poorly people understand complex systems and what education could do about it.

Richard Feldman's GOTO Copenhagen 2022 talk on why dynamic languages like Python, Ruby, PHP and JavaScript rose in the 1990s and why each now has a popular static type checker. It argues that modern static typing recovers the advantages that made dynamic languages attractive.

Gary Bernhardt argues that software history moves in reactions to earlier tools, and that new tools are not simply better in every way. He distinguishes capability (what a tool allows) from suitability (what it fits), and warns against repeating past mistaken reactions.

Curtis Poe's FOSDEM talk arguing that day-to-day Perl 6 is far simpler than its enthusiasts' talk of exotic features suggests. He compares basic math and string handling across languages.

Andy Keep's Clojure/Conj talk on writing a nanopass compiler, built from many single-task passes with formally defined intermediate languages. It covers the framework's origins in a compiler teaching course at Indiana University.

A 1987 talk in which John Backus, creator of Fortran, presents function-level programming and the FL language, a successor to his FP work. It is an archival recording with links to the related paper.

Richard Feldman argues that functional programming is not the norm largely because of historical accidents, such as C++ popularity, platform exclusivity, marketing spend and network effects, rather than merit. He traces the history of how languages become mainstream.

Robert C. Martin (Uncle Bob) traces the history of software from 1948 to today, looking at the problems programmers faced, how they were solved, and what mistakes the profession made. He then projects where the field is going, including professionalism and regulation.

Dylan Beattie's NDC London talk on code written for art, fun and curiosity rather than utility. It includes quines, live music programming with Sonic Pi, and a memorable closing.

A short SIGBOVIK 2017 presentation by Tom Wildenhain showing that PowerPoint animations are Turing complete, with a working Turing machine built in slides. The talk is delivered deadpan as a serious research result.

Damian Conway's hour-long keynote at the Perl conference, On the Shoulders of Giants, showing off Perl 6 (Raku) features with history, algorithms and a quantum math operator built with grammars. It is delivered with comic flair.

A 2008 Google Tech Talk in which Slava Pestov introduces Factor, a concatenative language influenced by Forth, Lisp and Smalltalk. It covers the interactive environment, metaprogramming, and the language's modern high-level features and libraries.

Bryan Cantrill argues that programming languages and platforms reflect core values, and compares languages through that lens, with Rust as a main example. He draws on his experience with Solaris, DTrace and ZFS.

Christopher Alexander's keynote at OOPSLA 1996 on patterns in architecture, addressed to the software community. He moves beyond patterns toward deeper ideas of wholeness and living structure.

Aaron Hsu's FnConf18 talk asks whether APL needs a static type system. He argues that APL's expressiveness and rapid iteration already deliver the benefits usually credited to types.

Alex Martelli's Google Developers Day talk on classic design patterns (creational, structural and behavioral) and how they appear in Python. He stresses that patterns must be studied in the context of the implementing language.

Aaron Hsu shows how to manipulate and transform tree data in APL using arrays and inverted tables instead of pointers. He claims much smaller code, better performance and easier parallelisation.

An AdaCore talk on the history, present and future of the Ada language, including remarks from Robert Dewar. The title and description say little else.

Jonathan Blow's Reboot Develop 2017 talk on making game programming less terrible, discussing software bloat, slowness and the design goals behind his own programming language.

Matthias Felleisen's keynote uses weather prediction as an analogy for type systems, arguing they forecast problems so you can act on them. It draws on his experience developing Typed Racket.

Yaron Minsky explains how Jane Street moved from mainstream languages to developing almost entirely in OCaml. He covers trading systems, research infrastructure, tooling and hiring.

A Google talk from the Chisel community in which engineers recount designing the Edge TPU with the Chisel hardware construction language. It covers the productivity gains and the problems they hit.

A DConf 2019 talk by Robert Schadek arguing that spreadsheets are the world's dominant programming language and that D can be used to replace them. It looks at spreadsheet quirks and then at techniques for moving away from them.
