Seymour Cray's only surviving recorded talk, introducing the Cray-1 supercomputer in 1976. He describes the machine's design, including its vector architecture and cooling through the frame.

Raymond Hettinger's PyBay 2017 keynote on concurrency in Python. It covers threads, processes, asyncio, locks and the GIL, with live shell-based examples.

Raymond Hettinger's PyBay 2019 talk on the mental habits behind effective programming, drawn from coaching, teaching and StackOverflow. He covers problem decomposition, chunking, managing working memory and getting unstuck.

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.

Raymond Hettinger explains Python's dataclasses module, showing the problem it solves and its key design decisions. He places it in a progression from tuples and dicts through named tuples and attrs.

Raymond Hettinger's PyBay 2019 talk on the mental strategies he uses when programming in Python, such as chunking, solving a simpler related problem, and repeating tasks manually until patterns emerge. This version is re-synced with the slides.

Raymond Hettinger's PyBay 2018 keynote on preventing, finding and fixing bugs under a time budget. He covers testing practice, type annotation tradeoffs and the limits of coverage metrics.

A Graphics Programming Conference talk on how the game Tiny Glade renders meadows, trees and player-built castles. It covers real-time global illumination, tilt-shift depth of field, stable shadows with continuous time of day, ray marching and GPU-driven rendering on old hardware.

Ray Kurzweil presents his book How to Create a Mind at Google, on reverse engineering the brain and using that understanding to build intelligent machines. He shows his graphs of exponential technological progress.

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.

Chuck Moore, creator of Forth, gives his annual Fireside Chat at Forth Day 2011 at Stanford. He talks about his multi-core GreenArrays chip design and demonstrates code running on it.

Python core developer Raymond Hettinger explains how Python's dictionary implementation evolved into the compact, ordered dict in Python 3.6. He uses pictures and small bits of pure Python, and covers key-sharing, compaction and versioning.

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.

Chuck Moore, inventor of Forth, presents GreenArrays' 144-core asynchronous chip at Strange Loop 2013. He explains how idle cores draw almost no power and how tight code minimizes energy use.

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.

Andrew Kelley, creator of Zig, presents practical data-oriented design techniques for shrinking memory footprint and making programs cache friendly. He ends with a case study of how these ideas sped up the Zig compiler.

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.

Mike Acton of Insomniac Games argues that a program's purpose is transforming data, and shows how common C++ approaches work against that in performance-critical game development. He covers cache behavior, data layout and the limits of compilers.

Johann Korndorfer's NVScene 2015 talk on building content with signed distance functions. It focuses on patterns that make SDF modelling more structured, arguing that SDFs capture a shape's essence like vector graphics do compared with polygons or voxels.

A 2014 talk by Geo Carncross (geocar) demonstrating kOS, a minimalist operating system and programming environment built around the k language, with early screenshots.

Aaron Hsu explains why programmers often find APL harder to learn than people with no programming background. He identifies eight patterns that contrast traditional software engineering practice with APL practice, starting from Ken Iverson's language design principles.

A JuliaCon 2016 talk by Shashi Gowda showing an APL implementation in Julia. APL code is translated to Julia and JIT compiled to machine code.

A short clip of Dr. Robert Zubrin, author of The Case for Mars, answering why humanity should go to Mars. He argues that societies grow by challenging themselves and that exploration inspires young people.

Kate Gregory argues at CppCon 2015 that C++ should be taught without starting from C: no char* strings, printf or raw arrays at first, with references before pointers.

Bryan Cantrill's 2007 Google Tech Talk on DTrace, showing how dynamic tracing improves debugging of both development and live production systems. It includes a vivid war story about tracking down a problem on a Sun Ray server.

Bungie's David Aldridge explains the networking programming behind Halo: Reach in a 2011 GDC session. It covers how gameplay stays in sync online, including forecasting and state reconciliation.

Noel Rappin's MountainWest RubyConf talk introduces Smalltalk to Ruby programmers. He compares the two languages' object models, blocks, 1-based arrays, simple syntax and live programming environment, and walks through sample code.

Tom Scott and Matt Gray talk at Electromagnetic Field about making Emojli, an emoji-only messenger that began as a joke, how it was built and why they never want to do it again.

Frederick Raynal gives a GDC postmortem of Alone in the Dark, the game that helped create the survival horror genre. He covers how the team built it and shows some of the old tools used.

Bryan Cantrill's talk on corporate open source anti-patterns, first given at FISL 2012 and again at the Liferay Symposium. He lays out the mistakes companies make when open sourcing code, such as announcing future open sourcing, and discusses licenses.

Elizabeth Gilbert, author of Eat, Pray, Love, reflects on the pressure placed on artists to be geniuses. She proposes the older idea that creative people have a genius that visits them rather than being one.

Google I/O 2011 session by Ray Cromwell and Philip Rogers on writing 2D and 3D games with HTML5 and GWT. It covers porting game libraries and physics engines, sharing code with Android, and publishing to the Chrome Web Store, and showcases the ForPlay library.

A Google Tech Talk by Raymond Blum on how Google backs up massive amounts of data such as Gmail and Picasa. It covers scaling challenges, failure types, and approaches that did not work, including tape.
