Max Brunsfeld introduces Tree-sitter, a parsing system for developer tools that offers incremental parsing and robust error recovery through a uniform C API. The talk explains the design, based on LR extended to GLR parsing.

Herb Sutter's CppCon 2019 talk on the split in the C++ community over exceptions and RTTI. He proposes making exceptions cheaper and more usable, including a zero-overhead, Result-like design.

NASA's animated explanation of the Curiosity rover's Mars landing, which relied on a complex automated sequence taking about seven minutes. It features NASA engineers discussing the risks before the 2012 landing.

Luca Sas's ACCU 2021 talk on Modern C, a style of C and C-like C++ aligned with data-oriented design. It covers centralized memory management, zero-is-initialization, error handling and API design.

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 Second Thought video arguing that the CIA is responsible for serious crimes, coups and unrest around the world, with historical examples and further reading.

Veritasium builds a QR code by hand to explain how it works. It covers the history of Morse code and barcodes, how QR codes encode data, why damaged codes still scan, and how safe they are.

Footage of a doubleheader of locomotives crawling over badly maintained track on a former Wabash Railroad line, now the ND&W Railway. The uploader explains the track had deferred maintenance for decades.

A short clip based on Zbigniew Brzezinski's views about the erosion of national sovereignty and his criticism of the war on terror. It is titled Political awakening.

Peter Shor tells the story of how he discovered Shor's Algorithm, from his early mathematics days to the quantum factoring breakthrough. It was recorded at MIT at the Physics of Computation conference.

Tom Scott recounts the worst typo he ever made, a subtle mistake in code with destructive consequences at a previous job. It is a cautionary tale about irreversible operations.

A short documentary clip of Japanese railway workers and Toyota staff using pointing-and-calling, a safety practice of physically pointing at and naming things while working. It includes examples from several railway companies.

Cockpit footage of an approach to the Megeve altiport in France that ends in a gear-up landing, with the warning horn audible throughout. Everyone aboard survived and the crew had thousands of flight hours.

A short video of railroad workers in Storfors, Sweden, using thermite to weld rail sections together.

Chess YouTuber agadmator reports that YouTube took down his podcast with Hikaru Nakamura as harmful or dangerous content. It was later restored.

Not Just Bikes argues that winter is not what stops Canadians cycling, using Oulu, Finland as proof that safe, well-maintained cycling infrastructure enables year-round biking despite harsh weather.

Casey Muratori argues against smart pointers and RAII, advocating grouped-element thinking, zero-is-initialization and stubs as better ways to structure memory and handle errors.

Evan Czaplicki, creator of Elm, discusses the hard parts of running an open source project: online community conflict, why its patterns arise, and a cultural history of open source. He offers ideas for more civil, productive communication.

MinutePhysics explains that computers store brightness nonlinearly, so blurring and blending colors in raw RGB gives wrong, dark results. It shows why mixed colors, such as in gradients, look off.

Anders Hejlsberg whiteboards how compilers are taught versus how modern ones are actually built. He explains the shift to compilers as services with incremental, error-tolerant, IDE-oriented design, as in Roslyn and TypeScript.
