cache optimization

Casey Muratori's first refterm lecture lays out philosophies of optimization, distinguishing optimization from non-pessimization, which means avoiding needless work. It uses his fast terminal renderer project to show how fast computers really are.

Kaze Emanuar explains how he rewrote and optimized the Super Mario 64 source code so it runs far faster on real N64 hardware. He covers performance bottlenecks and fixes in detail for his ROM hacks.

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.

Morphcat Games explains how they fit Micro Mages, a full-featured NES game, into 40 kilobytes. It covers compression of sprites and level layouts and other space-saving tricks.

Modern Vintage Gamer examines the claim from the Super Mario 64 decompilation project that the game shipped unoptimized, and puts it in the context of 1996 N64 development.

The winning demo from Revision 2015's oldskool competition, running on a real 1981 IBM PC with CGA at 4.77MHz. It uses extreme tricks to produce effects, graphics and sound far beyond what the hardware was thought capable of.

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.

Wes Bos breaks down the techniques behind the McMaster-Carr website's speed: server-rendered HTML, prefetching, CDN and service worker caching, preloading, critical CSS and fixed-size images. He also notes its old-school jQuery and YUI JavaScript.

A short clip of Casey Muratori from Handmade Hero explaining why he rejects the object-oriented mindset and how to move away from it. It is part rant, part programming philosophy.

Anders Hejlsberg introduces the native port of the TypeScript compiler, written in Go, which promises roughly 10x faster tooling. He demos compiling VS Code and explains where the speedup comes from.

A ten-minute clip from Jonathan Blow's talk on preventing the collapse of civilization, arguing that software quality and the knowledge to build it are in decline.

2kliksphilip examines UserBenchmark, a hardware comparison site known for strongly biased, pro-Intel writing. The video explains the site's credibility problems and points viewers to better sources for CPU and GPU information.

Digital Foundry investigates why Resident Evil Village on PC runs worse with Capcom's Denuvo DRM than a cracked version. They benchmark and confirm performance and frame-pacing differences.

A React Conf talk by Xuan Huang previewing React Forget, a compiler that automatically memoizes components. It argues for making memoization the default so developers need not write useMemo or useCallback by hand.

A 2013 research demo of simulated bipedal creatures whose natural gaits are found by optimizing muscle-based controllers, with no motion capture or keyframe animation. It shows physics-based walking and running emerging from musculoskeletal models.

Full gameplay of .kkrieger, a first-person shooter by Farbrausch that fits into a 96KB executable by generating its textures, models and sounds procedurally.
