Atari applied side art to arcade cabinets with screen printing (silkscreen), not stickers. Artists split designs into color layers, creating a separate screen and film positive for each color. Screens coated with light-sensitive emulsion are exposed, then washed to form a stencil. Ink is pushed through the screen with a squeegee, color by color, with precise registration to align layers. A semi-automatic flatbed press handled high-volume runs (e.g., Missile Command: 28,000 panels for 14,000 cabinets). The result is thick, vibrant, durable artwork.

Gary Bernhardt's PyCon 2014 talk "The Birth & Death of JavaScript" traces JavaScript and programming history from 1995 to 2035, candid about language flaws but optimistic about the industry’s trajectory. It links to his Destroy All Software screencasts for deeper programming insights and promotes Execute Program’s interactive courses on TypeScript, JavaScript, SQL, and regex.

The talk argues that becoming a billionaire is mainly about exponential startup growth, not luck or cheating. There are two key numbers: growth rate and how long the growth lasts. Growth comes from building something users love enough to tell their friends, creating viral expansion. The duration depends on market size; start with a beachhead and expand into adjacent markets. The best ideas often start as projects you and your friends want, not as clearly marketable concepts, and celebrities like Airbnb, Google, or Twitch began as experiments. Empathy for users, not exploitation, is the core startup skill.

PoC Rust tool that reimplements DD+ Atmos encoding to convert a DAMF (TrueHD+Atmos) into an E-AC-3 core with OAMD/JOC metadata in an EMDF container. It streams DAMF through a 5.1 downmix, encodes OAMD/JOC, and injects metadata into the core, delivering a memory-efficient, testable Atmos pipeline validated against Cavern/ffmpeg. It cannot produce hardware-accepted Atmos because EMDF signing is proprietary; to get true Atmos playback, feed the original TrueHD Atmos into an AVR (bypassing TV/eARC).

Space cooling: An orbital data center can shed heat by radiating to space. With P_sol ≈ κ A_sol and P_rad ≈ σ A_rad T^4, steady state requires P_sol = P_rad. For κ ≈ 150 W/m^2 and T ≈ 330 K, A_rad ≈ 22% of A_sol (≈32% at 300 K). A heat pump could reduce radiator area further at the cost of extra power. Earth-facing radiation and insulation add tradeoffs. In short, radiative cooling in space is feasible, with engineering challenges remaining.

Beagle is a git-compatible SCM that unifies local/remote Git resources under URI-based addressing. It moves versioning info into the URI query and uses HTTP verbs to drive operations: GET fetches data (including remotes), HEAD simulates a dry-run fetch/report, POST commits, PUT edits the reflog, DELETE removes, and PATCH applies another version's changes to the worktree. Merge/rebase/squash/cherry-pick are expressed as orthogonal operations; Beagle CLI demonstrates a compact set of patterns (be patch, be post) for various history-editing tasks. Beagle URIs like be://host/path?/beagle encode the project in the query, with branches indicated after /beagle.

Xerox PARC’s EARS linked the Alto to a SLOT laser printer via a dedicated RCG, moving the heavy page-processing off the host. Ear printed text; Bravo allowed mixed fonts and images; when pages became complex, Sproull and Newman introduced Press, a page-description language that encapsulated layout and vector data for the RCG. This enabled real-time, networked printing over Ethernet. A commercial offshoot—the 9700 Electronic Printing System—sold well but was unwieldy. The broader network-computing potential was missed, shaping later PostScript, the Macintosh, and Adobe; Starkweather cites imagination as key.

Garrit's Notes argues that LLM context windows split into a "smart" zone and a "dumb" zone; only about 100k tokens remain reliably useful, so huge advertised windows are marketing. As sessions run long, attention drops and earlier details fade; auto-compact helps but only after damage. Best practice: start a new session with a manually written spec, then move crucial history into artifacts (PRDs, plans, skills) for future handoffs. Build workflows around small, named artifacts, treating context as a budget to keep the live session in the smart zone.

Phoenix LiveView 1.2 is released. It expands Colocated CSS for HEEx templates, allowing CSS to be colocated and scoped using a phx-r attribute and phx-css-* markers, with @scope-based scoping available as an opt-in approach (not shipped by default due to browser support). The release also updates HEEx compilation to a separate tokenization/parsing step to support colocated CSS/JS. Small improvements include an HTMLFormatter.TagFormatter, auto-encoding of Phoenix.LiveView.JS structs with Jason or the built-in JSON module, per-module HEEx debug annotations, and configurable test warnings. Update mix.exs to ~> 1.2.0.

At Forest Lawn Glendale, a fleet of purpose-built groundskeeping and support machines keeps the cemetery running alongside its classic hearses. The collection includes a dirt hauler, a casket loader, a custom flatbed, and a wide John Deere mower; all are bespoke machines from the 1950s onward, refurbished with modern powertrains. Functions: the dirt hauler excavates burial sites, the casket loader moves caskets, the flatbed transports tents and gear, and the mower covers 250 acres. The hearses themselves are vintage Cadillacs. The author notes a summer cars-and-coffee event where these machines are showcased.

Anthropic tested Claude on NMR tasks to help chemists translate between representations. In forward NMR prediction, Opus 4.7 matched or outperformed ChemDraw and MestReNova for ¹H and ¹³C shifts and better reproduced splitting; across three Claude runs vs. single classical tool runs, Opus 4.7 was the most accurate and consistent. In inverse structure elucidation, Opus 4.7 recovered eight simple structures from spectra and HRMS every time, and solved most harder targets when given starting-material hints. Limitations include small, scaffold-limited data, absence of 2D experiments, and limited solvents. They plan broader chemistry work and invite collaboration.

Tribblix is an open-source operating system based on illumos that blends retro styling with modern components. The project released Milestone 40 on June 12, 2026, with X86 release notes; SPARC m34 ISO is now available, alongside upgrades from m33. Note: 32-bit hardware support has been removed; SPARC support remains less tested, while the x86 version is solid. You can download the image, install to a hard drive, and use it.

SQL to ER Diagram is a free, open-source, client-side tool that converts SQL CREATE TABLE statements into an interactive ER diagram in your browser. Paste standard DDL, and the app renders tables, columns, primary/foreign keys, and constraints; supports PostgreSQL, MySQL, SQLite, and SQL Server. Drag to arrange, rename, add notes, and export as PNG or SVG. All processing is local—no signup, no uploads. You can save your project or share via a URL encoding the diagram.

Garrit's Notes introduces a small game: Pac-Man, but you play as the ghost. Your objective is to catch Pac-Man before he clears the maze; Pac-Man has AI and can be captured. If he eats a power pellet, the tables flip and he hunts you for a few seconds before you run. A link to play is provided.

Martin Fowler frames software architecture as the set of important design decisions shared by developers, central to evolving systems, and inseparable from programming. Architecture matters because poor internal quality creates cruft that slows delivery; high internal quality speeds feature work. Definitions vary: architecture as fundamental structure, or as decisions that matter early. Applications are social constructions with boundaries defined by team and business perception, while enterprise architecture coordinates across many systems. The guide covers patterns and topics (microservices, serverless, UI patterns, layered data, legacy displacement) and emphasizes iterative, incremental change.
