Peter Fritz, an Austrian insurance clerk, made 387 cardboard models in the 1950s–60s depicting an imaginary Austrian town from everyday vernacular architecture—banks, gas stations, farms, houses, fire stations—recomposing structures he encountered. Forgotten in plastic bags, the models were rediscovered by artist Oliver Croy and shown at the Venice Biennale, framed as a visionary, encyclopedic survey of regional typologies rather than conventional artworks.

Nicolas Mattia presents Skapa, a 100% client-side parametric app to generate 3D-printable boxes for IKEA Skadis pegboards. The web app mimics an IKEA manual, using Kanit, orthographic views, and minimal UI. Users set width, height, depth to export an STL ready for printing. Generation uses manifold-3d (Wasm); rendering uses Three.js with handcrafted edge-detection shaders for thick outlines. Code on GitHub and Printables; future plans include more models and printing tweaks (supports now optional).

The article traces how early 'home computer hybrids' merged PC flexibility with cartridge-based games, focusing on Atari and TI. Atari’s 400/800 (the Home Computer System) blended advanced color graphics and sound with cartridge expandability, becoming a leading home computer for games while facing stricter FCC RF rules, which drove it toward a shielded, all-in-one design with a single SIO. TI’s TI-99/4 aimed for a high-end, integrated package but flopped on price, keyboard, and software control. The 1979 FCC regs broadened testing to all PCs, elevating costs and hastening the shift to a broader home-computer market—the home computer wars.

Wildfires are driven by more than flames: underground 'zombie' fires in Canadian peatlands can overwinter and reignite, creating a dangerous carbon feedback. Most ignitions are human, but large fires are often lightning-driven in areas. Terrain accelerates uphill spread; embers account for the majority of property loss through spotting, sometimes miles ahead. Big fires create their own weather (pyroCb, fire tornadoes) and threaten aircraft via mountain waves and microbursts. Satellites provide broad hotspot data, while FBANs and models (Canadian, Australian systems; Prometheus/WISE; Spark) translate data into scenarios. Not all fires should be extinguished; priorities balance safety, people, property, and environment.

Ernie Smith argues that scrolling window managers are a practical UX shift for Linux. He traces PaperWM from a GNOME extension to a broader idea: windows slide with keystrokes, like swiping between desktops on every window. He contrasts tiling and GNOME's heaviness with Niri and Hyprland, then highlights Dank Linux—a 'modern desktop for Wayland' that bundles DankMaterialShell with a cohesive, extensible toolkit built on Quickshell. DMS offers built-ins, theming, and plugins, aiming to be less prescriptive than Omarchy. The setup is customizable; glitches exist, but the approach feels like a major, welcoming step forward for desktop Linux.

Gioia argues we’re in a “New Romanticism” countering rationalism, surveillance, and AI-driven control by reviving love, trust, creativity, enchantment, and human dignity. He likens it to the 1800s Romantic backlash and offers 25 propositions on how to rebalance society so people serve the system, not vice versa. He warns against AI's pretenses, the emptiness of data-driven life, and notes the movement is already spreading through culture, media, and public commentary, with private healing as a starting point.

Mike Swanson argues software has shifted from a tool to a channel that interrupts users. Tracing the shift: software on disks; online updates; backchannels and telemetry; analytics turning usage into engagement metrics; A/B testing making teams run experiments on people; nudges and prompts becoming pervasive; push notifications magnifying interruptions; while some alerts are defensible, incentives chase metrics at the cost of trust. Builders dislike this pattern. Solutions: opt-in interruptions with durable opt-out; separate health telemetry from growth data; analytics as a flashlight, not a steering wheel; ship a true quiet mode. Aim for software that helps, not dominates.

The article describes 'Hi Writer Authentic Author', a writing tool that aims to capture real human thinking. Users receive a prompt and must write 1–2 paragraphs directly in the editor without any AI assistance. Pasting and DOM manipulation are disabled to ensure originality. The tool tracks telemetry (typing speed, pauses, tab changes, window focus) and generates an Authenticity Score intended to predict the likelihood that the writing is original.

Caries are a communicable disease driven by Streptococcus mutans transmitted mainly from mothers; diets rich in sugars acidify the mouth and demineralize enamel, creating cavities. The article surveys caries through human history, linking rise to agriculture and sugary diets, and notes that untreated caries remains a global burden, especially in the poor. While brushing, fluoride, and dental care have reduced suffering, elimination remains elusive. A potential one-shot solution is a LDH-d S. mutans–based vaccine (BCS3-L1/ mutacin 1140) that colonizes mouths and prevents caries, offering a path toward preventive dentistry.

Proposes that employers stop digital job applications and require postmarked, physical letters, ideally with handwritten cover letters. The author argues physicality would raise costs for applicants and hinder LLM-based automation, possibly improving application quality and authenticity (even suggesting carbon imprint and witness-verification). They acknowledge significant barriers—handwriting quality, stamps, cost, and practicality—and doubt employers will actually switch. They foresee companies turning to third‑party AI‑protection systems instead, and describe the current online‑application race to the bottom as relentless and disheartening.

Pullum demystifies the English passive. A passive clause has a participial verb form and a non-subject NP inside the verb phrase, with the subject often the victim rather than the agent. The auxiliary be provides tense in many cases, but many passives avoid be entirely; prepositional and "pseudo-passives" with stranded prepositions are common. Bare passives appear in headlines; concealed passives use -ing (need, etc.). Passivity is a functional, versatile construction, not a deficit, and prescriptive guides against it are misguided. The post offers precise terminology and examples.

AI coding agents can accelerate software creation, but reliable systems must separate judgment from execution. Neural nets handle fuzzy judgment; execution should be traditional software for determinism, auditability, and edge-case handling. The proposed architecture keeps the runtime in tested code, while AI-driven judgment at build time emits artifacts—like selectors or code—into version control and deployment. If failures occur, AI can rewrite the artifact. This adaptive symbolic software blends fast buildtime learning with auditable, deterministic runtime, a pattern Docflow Labs promotes while noting industry risks.

GPUs render triangles, not curved surfaces. To show curves, tessellate them into triangle meshes. A mesh is two arrays: vertices (x,y,z) and indices (triples). To tessellate a surface, sample its parametric form on a grid (u around 0..2π, v along height), then form triangles between adjacent samples. Fewer samples = faster, rougher; more = slower, smoother. Flat faces can be fan-triangulated; cylinders use a circular-UV grid; spheres use latitude/longitude, with pole corrections. Holes require bridging the inner and outer boundaries into one polygon, then ear-clipping to triangulate. The output is TriangleMesh { vertices, indices }—the canonical CAD/GL/physics format.
