Ben Vallack walks through designing a custom keyboard PCB from scratch using Ergogen and KiCad, ending with a gerber file ready to order from a PCB fabricator. The example is a split keyboard.

Emery Berger argues that performance is hard to measure and deliver on modern systems, showing how code layout and link order can swamp optimization effects. He presents tools that evaluate performance more reliably.

Emery Berger explains why performance is hard to measure and deliver on modern hardware, showing how code layout and alignment can swamp optimization effects. He presents Stabilizer for statistically sound evaluation and Coz, a causal profiler.

Andy Bell's 2022 talk on hinting the browser rather than micromanaging it, using progressive enhancement, CSS layout, fluid type and space, and modern CSS to build resilient front-ends.

Ben Vallack compares finger movement on a staggered keyboard with an ortholinear grid keyboard, using an Anne Pro 2 and a ZSA Planck EZ. He argues the stagger forces awkward finger motion.

A hobbyist builds a prototype full-frame CCD camera from scratch, with open-source design files and a custom PCB. The video shows the first, still rough prototype.

Jack Moffitt presents Servo, an experimental browser engine written in Rust and designed to be parallel at every level, using multiple cores, the GPU, fork-join concurrency and SIMD. The talk covers motivations, architecture and plans for the project.

A NeXT, Inc. promotional video showing its highly automated factory and the manufacturing of the NeXT Cube, including automated circuit board assembly.

Strange Parts spends four months, seven custom circuit boards and several disassembled iPhones adding a working headphone jack to an iPhone 7 in China. The build is documented in detail.

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.

Chandler Carruth's CppCon 2014 talk on writing fast C++, explaining why data structure choice and memory layout matter more than clever algorithms. It covers why standard containers like unordered_map perform poorly on modern CPUs.

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.

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.

3Blue1Brown explains space-filling curves and the Hilbert curve, and how infinite mathematical constructions connect to finite, practical approximations. It touches on mapping between dimensions and sensory ideas.

Nicholas Ormrod's CppCon 2016 talk on how Facebook optimizes std::string with its open-source replacement fbstring. It covers storage layout tradeoffs, small string optimization and memory allocation behavior.

Scott Meyers explains how CPU caches work and why they matter for performance, covering cache levels, access speeds, associativity, and effects in multithreaded code. The focus is C++ and cache-aware, data-oriented programming.
