Antithesis engineer Bill Grieser narrates a side project to beat Tetris via a deterministic fuzzer and emulator. Starting with random inputs, they develop a graph‑aware strategy that saves game states as nodes and searches the best path toward deeper levels. They reach level 160 but stall due to a bug: the line counter’s high byte was misinterpreted as BCD, so 1600 lines looked like 1000, making progress appear negative. After fixing it, they reach rebirth at level 255, matching and then surpassing teen players. The tale highlights glitches, persistence, and software humility.

An introduction for computer scientists explaining that eukaryotic genomes are encoded in DNA within nuclei. The genome (complete hereditary instructions) comprises genes that encode proteins; cells read genes to produce proteins. The bakery analogy helps: genome is the master recipe book; proteins are the cakes. DNA is ~3 billion bases, two complementary strands with base pairs A-T and G-C. In humans, DNA is organized into chromosomes housed with histones; 22 autosomes plus sex chromosomes (XX or XY). The genome is a vast search space; genotype-phenotype relationships link genetic variation to traits and diseases, including cancer, enabling personalized medicine.

Access to the YouTube video is blocked by Google due to unusual traffic from the user’s network, likely from malware, a browser plug-in, or automated requests. The block will expire shortly after traffic stops; solving the CAPTCHA will restore access. If on a shared network, ask an administrator to check the IP. CAPTCHA may trigger for fast or bot-like activity. JavaScript must be enabled to continue.

ModelMap visualizes AI model benchmarks as a 3D shape, where spike height indicates score. It pulls public benchmarks live from Hugging Face model cards and averages across scored benchmarks. Users can compare models, save defaults, and adjust visualization options (color schemes, scale types, shape styles). The visuals do not alter the data. Interactive controls include WASD flying, mouse/touch rotation, scrolling to zoom, and clicking spikes for details; hover tooltips and mobile rotation are supported.

Anthropic spends about 2.3x its payroll on compute, roughly $515k per engineer per year at a $224k fully loaded salary. Top 1% spend ~ $89k/engineer/year; median ~$137k. Three 2029 scenarios (Bear/Base/Bull) project AI spend per engineer rising from about $90k in 2026 to $106k Bear, $363k Base, or $596k Bull in 2029, i.e., 41%, 140%, and 230% of salary respectively. In the Bull case, AI bill could rival a median SaaS revenue per employee. Drivers: frontier model pricing, token use, and strategies to ration usage.

This article extends the Part 1 C++ unit-test approach to fix per-file counters and ODR by moving state into a shared named namespace with inline variables and updated, fully-qualified macros. It then presents a module-based version: a test.cppm module exporting TestFramework (nPass, nFail, fail, test, succeed, report) and a separate test_macros.h to bridge macros, using std::source_location and std::string_view. Recommendation: prefer header-only for portability; use the module version only when toolchains robustly support modules, often via a hybrid approach.

Shrimple is a cleaner Markdown-like language that renders to HTML. It supports installation with Go and usage by piping a source to shrimple (flags -s/--default-css and -w/--wrap). It includes parse & render dictionaries for word highlighting, and a static-site generator that converts a Shrimple directory into HTML with optional navigation and menus. Links stay clean using footnotes; code blocks use 6-space indentation (optionally labeled with a language for syntax highlighting); lists and two header types (h1/h2) with underlined separators. Examples show building and generating a site (examples/StaticSite).

Pollan argues that novelists’ depictions of the stream of consciousness—Woolf, Joyce, and others—provide essential insights into consciousness that neuroscience often misses. He traces how spontaneous thought, once feared as madness in Victorian times, came to be valued as a truthful window into mind, influenced by Freud, physics, and modern life. The piece contrasts verbalized thought with nonverbal mind-stuff and shows how culture shapes our understanding of cognition. Adapted from A World Appears.

Castro's founder describes trying to differentiate with human, daily-use support and even paying a frequent user to handle emails. While some rapid fixes delighted a few customers, most honest replies proved unsatisfying or counterproductive. He catalogs support types—pricing complaints, bugs, nuanced questions, confused customers, and generic feature requests—and finds few of them build rapport. Ultimately, deep human intervention is not a reliable differentiator; better results come from improving the product and communicating appreciation rather than detailed explanations.

Havel argues that ideology under power structures becomes reality itself in post-totalitarian systems, as power relies on ritualized 'world of appearances' to maintain legitimacy. The regime protects this lie even as truth threatens it; living in the truth becomes the most potent form of political resistance, rooted in the hidden sphere of conscience rather than institutions. Dissidents arise from ordinary lives—artists, workers, teachers—who preserve a 'second culture' and create parallel structures (samizdat, private associations) that cohere as a 'parallel polis.' These structures undermine the regime and point toward post-democratic, human-centered renewal emphasizing trust, openness, and self-management.

Wearable hardware and small devices are proliferating, and the software gap is shifting from device builders to everyday developers. The real value will come from software written close to sensors, not in data centers. But current embedded toolchains block web-like development. GEA proposes a solution: a single TypeScript-based codebase compiled ahead-of-time to native, targeting MCU, embedded Linux, macOS, iOS, etc. This moves the software boundary up the stack, letting web developers build native interfaces for personal hardware without mastering firmware. Hardware manufacturing and certification remain hard, but more people can write the software that runs on devices.

Author argues Fortran remains indispensable for scientific parallel computing but suffers from an image problem and aging workforce. He proposes modernising it with a dependently typed FP-inspired language (Φ/𝓕) that compiles to core Fortran, trimming boilerplate and discarding fixed-format and implicit typing, OO and pointers. It adopts ML-style syntax, dependent types, ADTs, pattern matching, type classes, and modules, delivering a FP-first design with proofs of correctness. It would integrate CAF/PGAS parallelism, interoperate with Python and other languages, and be targetable by modern languages while preserving a Fortran core. A multi-pronged strategy in academia, industry, and tooling is urged.

sneakerweb is a peer-to-peer, permissionless web publishing protocol with no DNS or hosts. Websites reside on user devices and transfer via physical storage media, viewable offline in a normal browser and shared as .snk files. The sneakerweb CLI manages a local collection, enabling exporting/importing .snk files, creating sites, claiming domains, publishing to domains, blocking domains, and starting a local server. The protocol, built on Willow, prevents forgery, merges updates, and keeps .snk files compact.

The author surveys historical writers famed for extreme output, from Chesterton to Tellado to Lope de Vega, Dumas, Balzac, Simenon, Cartland, and modern China’s Wǎngwén, showing how they sustained prodigious writing through ritual, discipline, collaboration, and industry pressures. The piece emphasizes that for these writers the act of showing up daily mattered more than fame or quality; compulsion, not hustle, drives creation. The author reflects on his own writing habit, noting continuity and the human cost, and suggests the value of consistency and dedication in writing.

To prevent agents from breaking themselves, use sandboxed execution inside disposable Sprites. The agent loop runs models and tools, but dangerous commands should not run in the host sandbox. SpriteDoc creates a fresh Sprite per session, isolating filesystem access and never storing user tokens long-term. Hermes keeps one Sprite per task so it can reuse installs, while still executing commands in a separate Sprite. Checkpointing via copy-on-write lets you undo harmful steps quickly. The result: durable agent homes and safe, unattended operation.
