Jeremy Keith decries the ‘magic’ marketed around technologies—the idea that things just work without user control. He argues that seamless UX often reduces agency, and he distrusts dependencies and abstractions, especially frameworks like React, preferring to stay close to raw HTML, CSS, and JavaScript. Acknowledging pragmatic value of large-language-model coding tools, he warns that extra layers of abstraction complicate maintenance and documentation, and can trap projects in fragile code. For long‑lived work, he champions handcraft and clarity over shortcuts, even as tools proliferate.

The Denonomicon is a third‑party guide to Deno's Foreign Function Interface (FFI), aiming to fill gaps left by the Deno Manual and focus on interfacing Deno with C APIs, not TypeScript. It covers basics and advanced topics: types (booleans, 32/64-bit ints, floats), pointers, functions, structs, and callbacks (synchronous, interrupt, thread-safe), V8 fast API, security, and interfacing with non-C libraries. It also discusses C++ conventions (calling conventions, inheritance, std::function) and the future of Deno FFI. The author disclaimers and logo credit are noted.

To ensure you run exactly the advertised model, Tinfoil's Modelwrap cryptographically commits to the weights (a Merkle-tree root) and binds this commitment to a secure enclave using dm-verity so every read is verified at runtime. It works with public or private weights: download and hash weights, produce a .mpk image, pass root hash to the kernel, and dm-verity rejects any tampered block. No code changes required; supporting unmodified model servers. Overheads are small (~0.8% extra storage); initial load is slower but inference remains fast.

Hydrogen propulsion remains hampered by weak infrastructure and BEV competition, driving severe Mirai depreciation. The Mirai, the first mass-produced hydrogen car, has seen used prices collapse from about $50k (2021–2025) to as low as $10–18k, with some around $22k. Availability is California-focused; the US has only 54 hydrogen stations, many unreliable or costly to fuel. This limits buyers and makes maintenance specialized. Toyota persists with hydrogen efforts (North American HQ, BMW collaboration) and synthetic fuels as alternatives. Despite ongoing availability (2026 model) and incentives, Mirai sales were only about 210 units in the U.S. in 2025.

canvas_ity is a tiny, single-header C++ library that provides an immediate‑mode, canvas‑like 2D rasterizer modeled on the HTML5 canvas spec. It aims for high‑quality rendering with gamma‑correct blending, bicubic resampling, antialiasing, and careful line joins, while remaining small and dependency‑free. It is header‑only, portable (C++03), thread‑safe per canvas, and uses std::vector for memory; no GPUs or external pointers. Usage: include the header, define CANVAS_ITY_IMPLEMENTATION in one file, construct canvas(width, height), draw with the API, then get_image_data() to retrieve RGBA pixels. License ISC; example writes a TGA; tests included.

The post argues for Type-Driven Design in Rust: encode invariants in types rather than rely on runtime validation. Through examples like NonZeroF32 and NonEmptyVec, it shows how making illegal states unrepresentable—with fallible constructors and newtypes—pushes validation to the caller and reduces runtime panics. It contrasts weakening return types (Option) with stronger parameter guarantees, advocates parsing data into typed structures (e.g., String, serde_json via Deserialize), and warns against shotgun parsing. Concludes that Rust’s type system can and should handle validation to improve correctness.

An overview of input lag in gaming, defining it as the delay between user input and on-screen reaction, noting its rise as systems grew more complex. It highlights the difficulty of achieving early-2000s latency without image degradation and calls for understanding and addressing latency. The site presents the lag chain's three components—controller, game engine, and display—focusing on measuring and explaining issues, especially the controller and engine, to help developers and consumers tackle latency.

An ex-CIA analyst describes decades of polygraph experiences across CIA, FBI, NRO, and DIA. She prepared with Lykken, intended to answer honestly without countermeasures, yet faced brutal, scripted interrogations, multiple failed tests, and “random” re-tests spurred by Ames. She notes a recurring pattern: inexperienced examiners, then harsher later rounds, and how the culture of polygraph undermined trust and well-being. After refusing a DIA CI poly, she was terminated from a project. She concludes polygraphs are a deal-breaker, even as she loved the work.

Cloudflare faced a 6h7m outage on Feb 20, 2026, due to a change in BYOIP address onboarding that unintentionally withdrew about 1,100 prefixes, including one.one.one.one, causing many services to fail. No cyberattack occurred. Restoration involved reverting the change; about 800 prefixes were restored by 20:20 UTC and ~300 more were manually restored by 23:03 UTC. Root cause: a bug in a cleanup sub-task that treated pending_delete as a request for all prefixes, compounded by incomplete staging/testing. Cloudflare will adopt safer rollouts, API standardization, and improved rollback under Code Orange: Fail Small.

Permacomputing is an ecologically minded approach to computing that aims to maximize hardware longevity, minimize energy use, and rely only on resources already available. It promotes repairable design (disassembly, encapsulation), salvage and collapse computing to sustain knowledge through infrastructure failure, and frugal, reversible, and malleable systems that can be recombined across environments. It favors bootstrappable builds, open sharing, and emulation via a universal virtual computer for preservation, plus resilience concepts (agility, preparedness, elasticity, redundancy) to sustain a knowledge commons after collapse.

Les Earnest recalls his boyhood cryptography hobby: after reading a cipher book, he and a friend created a secret code and hid the key in a glasses case. A lost case was found and turned to the FBI, triggering a six-week investigation of a 12-year-old. An agent returned the glasses but kept the code key. Years later, while applying for a security clearance, Earnest noted he had been suspected of espionage; the officer tore up the form and told him not to mention it, and he was granted clearance. He later learned provocative information can speed clearance.

Colin Gorrie’s Dead Language Society article compresses 1,500 years of English into a single blog post, where a modern traveler’s diary gradually shifts into Georgian, Elizabethan, and Old English voices. Through staged passages, it highlights how spelling, letters (thorn, wynn, yogh, long s), vocabulary, and grammar changed over time, and how social forms like thou vs you altered meaning. Comprehension plunges around 1200–1300 as Latin/French loans fade and syntax loosens; Old English inflects, Middle English tightens word order, and by the 1700s spelling standardizes. The piece shows language evolves even as readers struggle to follow.

China’s CXMT is undercutting the DRAM market by selling DDR4 chips at about half price, even as Samsung and SK hynix race to HBM4. With prices high from a supply squeeze, CXMT is drawing interest from HP, Dell, Asus and Acer amid subsidies. CXMT is converting about 20% of its Shanghai wafer capacity to HBM3/HBM3E and aims mass production next year. YMTC is gaining NAND share and building a Wuhan fab, with half output to DRAM. The strategy: build scale in legacy DRAM first, then move up; risk to Korean profitability if the mainstream market shrinks.
