Robert 'Uncle Bob' Martin speaks at Yale School of Management about clean, well-written code and what makes good software development. The talk covers his views on OOP, architecture and professional practice.

Michael Feathers' GOTO Chicago 2018 talk on reducing error checks and conditional logic in code. He offers a framework for handling errors and decisions at the level of code and architecture.

A tool-assisted speedrun of Pokemon Yellow on Game Boy Color that uses glitches and frame-precise inputs to make the game execute an arbitrary program. It was later obsoleted by an improved run.

Greg Young's Code on the Beach 2014 talk on CQRS and event sourcing. He argues mature domains are built on facts that occurred rather than current state, and covers the business and technical benefits.

Erlang co-creator Joe Armstrong's Code BEAM SF 2018 keynote revisits good ideas from the history of computing that were dropped, and asks which should be revived. It also touches on Erlang and Elixir.

Joe Armstrong, creator of Erlang, and Jeremy Ruston, creator of TiddlyWiki, discuss hypertext, Ted Nelson's idea of intertwingled knowledge, and a way to combine TiddlyWiki with Erlang. It is a Code Mesh LDN 2018 talk.

Jason Turner's CppCon 2016 talk builds a simple Commodore 64 game using C++17, showing how constexpr and const let a modern compiler produce tight 6502 code. He walks through assembly output to show abstractions being optimized away.

Raymond Hettinger's PyCon 2013 talk on transforming code into idiomatic Python through a series of before-and-after refactorings. It shows how to use iterators, dictionaries, named tuples and other language features well.

A 2018 GDC talk by NetherRealm's Michael Stallone on the engine changes, optimizations and tooling needed to roll back and re-simulate up to 8 frames in 16 ms in Mortal Kombat and Injustice 2. It is a deep dive into deterministic rollback netcode.

GDC 2019 session where Insomniac's David Santiago describes the procedural systems used to build Manhattan for Marvel's Spider-Man. It covers the open-world pipeline and how each system was designed to support iteration and dependencies.

A condensed rendition of a project that re-uploaded one video to YouTube 1000 times, showing the accumulating compression artifacts. It pays homage to Alvin Lucier's I Am Sitting in a Room.

Edwin Brady presents Idris 2, a rewrite of the Idris dependently typed language, and shows type-driven development in practice. The demos show the compiler filling in whole functions from their types.

Code Rush is a one-hour documentary following Netscape engineers in Silicon Valley through the company's last year as an independent firm. It covers the Mozilla open-source announcement, the frantic push to ready the source for release by March 31, 1998, and the toll on engineers' lives before the AOL acquisition.

David Beazley's PyCon India closing keynote, in which he live-codes a stack machine and grows it into an interpreter that runs WebAssembly, then uses it to play a Rust-written game. It requires no prior WebAssembly knowledge.

Bryan Cantrill's Monktoberfest 2016 talk on how software engineers pass knowledge down through oral tradition, from folk rhymes to programmer lore and stories like why C lacks a logical XOR. He argues for writing software with future generations in mind.

A short !!Con 2016 talk by blind developer Sina Bahram on how he uses a computer and writes code with a screen reader at about 1,000 words per minute. He plays how common interfaces sound and challenges the audience to go a day using only the keyboard.

Brian Will follows up his earlier anti-OOP video by walking through four short code examples, including Java code in the style of Uncle Bob, to show how object-oriented design complicates simple programs. It argues that OOP hides and scatters state and adds needless indirection.

Irving Finkel of the British Museum lectures at the Royal Institution on the invention and decipherment of cuneiform writing in Mesopotamia, and why it is so hard to translate.
