object-oriented programming

The first part of a series on programming in Jai, Jonathan Blow's in-development language. It covers compiling, writing hello world and using code from other files.

A clip of John Carmack on the Lex Fridman podcast discussing his programming setup, why he favors debuggers and IDEs, and his puzzlement at developers who avoid them.

Applied Science shows how telecentric and hypercentric optics differ from normal lenses, producing no or negative perspective. The video builds a telecentric system from a Fresnel lens and demonstrates a lens that can see around objects.

Robert Miles gives a remastered introduction to AI safety, adapted from a talk in London. It lays out why advanced AI could go wrong and answers common objections.

Modern Vintage Gamer explains how Eric Chahi built Another World on the Amiga 500, using 2D polygons, rotoscoping and clever techniques to run well on a stock 7MHz machine.

Aaron Boodman of Replicache asks why sync engines have not yet fixed web app complexity and what is missing for them to go mainstream. The talk lays out the ideas that led to the Zero sync engine.

Matthias Wandel tests old and new code on a range of PCs, including a new mini PC, to measure how much faster modern hardware really is. He also shows optimization techniques such as branchless code, with benchmark programs on GitHub.

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 comedy sketch by Kai Lentit in which a senior JavaScript developer is interviewed, parodying the chaos of the JavaScript ecosystem.

The Michigan TypeScript group shows the Doom engine running entirely inside the TypeScript type system. It is open source, and two follow-up videos cover why and how they did it.

Kai Lentit's comedy sketch parodying an interview with an FFmpeg enthusiast. It pokes fun at the open source command-line tool experience and video conversion woes.

Acerola explores building a shader that turns games into ASCII art, walking through techniques such as brightness mapping and edge detection to see whether it looks good.

Leandro Facchinetti explains why he thinks Racket is a great language and why he stopped using it. He describes his backstory and experiences with the Racket community.

A JuliaCon talk by a NASA Launch Services Program engineer on modeling spacecraft separation dynamics in Julia. He describes replacing a Simulink-based workflow for checking launch vehicle separation requirements with Julia and ModelingToolkit, with large speedups and much shorter code.

The first lecture in Martin Kleppmann's 8-lecture distributed systems series from the University of Cambridge undergraduate course. It introduces the subject, and accompanying lecture notes are available.

Veritasium explains, with expert input, that in general relativity gravity is not a force and objects follow straight paths through curved spacetime, including why standing on the ground means you are accelerating.

Allan Blomquist demonstrates the internal programming and debugging tools Tomorrow Corporation uses to make games, including live modification of a running game and time-travel debugging.

A five-minute video showing how to build a counter in the Imba web programming language in under a minute, then style it.

Not Just Bikes argues that North American transit struggles to attract riders because of the land use around it, not the transit itself. It uses examples such as a London, Ontario line with unreachable stations.

Asianometry examines why Japan's software industry has lagged despite its hardware strengths. It looks at dependence on US software and the low prestige of programming.

PBS Space Time explores whether time causes gravity, explaining that gravity does not truly warp the flow of time but arises from time gradients. It revisits how gravitational time dilation works in general relativity.

Scott Manley explains the Cold War experiments in which steel and aluminium spheres, known as Lew Allen's Balls, were placed near nuclear detonations. The spheres survived the fireball, and he walks through what the declassified results show.

Michael Reeves rigs up a camera and software that tracks a goldfish's movements to choose stock trades, tied to wallstreetbets sentiment. It is a comedic programming and electronics stunt.

An animated Gabbard diagram of objects in low Earth orbit from 1959 to 2021, showing altitude over time. It highlights major debris-generating events and how low-altitude debris decays out of orbit.
