An Italian regional bank in Emilia-Romagna lends to Parmigiano Reggiano producers by taking wheels of cheese as collateral, then stores and cares for them in a climate-controlled vault for 1–3 years. The loan, about 60–80% of wheel value, lets producers access cash now while awaiting aging. The bank’s warehousing arm inspects, rotates, and brands wheels; failure to pass quality leads to resale. Cheese is ideal collateral: standardized, durable, and increases in value with age. The vault holds hundreds of thousands of wheels worth hundreds of millions.

Herman Hollerith, frustrated with census counting, invented an electric counting machine using punched cards. The Hollerith tabulator, tested 1888–89, captured data fast and drilled cards through readers/sorters, producing binary on/off signals. For the 1890 census it reduced labor from years to six months and saved about $5 million; per capita costs fell even as population rose. The system spurred commercial use in railroads, stores, utilities, and laid the groundwork for data processing and the binary method. Hollerith founded the Tabulating Machine Company; in 1911 it merged into CTR, later IBM. He remained as consultant; IBM grew from there.

celld is a self-hosted, distributed Durable Objects platform. Your Workers and DO code run unchanged, with data stored in a bucket you own. A central bucket coordinates ownership; a built-in replicator ships each cell’s SQLite state as LTX to that bucket, keeping state consistent across nodes. Ownership is granted by atomic writes, so a node failure de-leases and re-allocates cells with minimal disruption. Deploy via a small installer or Docker. Cost scales with resident cells and is designed to be cheaper than managed DO at scale, while preserving the DO model.

Penpot's 'Three-Stroke Problem' frames three stroke types—inner, center, outer—on a shape as chaotic, mirroring the three-body idea. A stroke is a border around a layer; CSS borders are usually inner, SVG defaults to center, and outer/center/inner require clips or outlines. The article compares CSS, SVG, and Skia-based WebGL: Penpot's WebGL renders multiple borders by drawing outer, center, and inner strokes in sequence with Skia (outer via outset, inner via inset, center native). For complex shapes, paths need extra tricks (clips/masks). Conclusion: WebGL/Skia offers more border flexibility than SVG and enables future features like per-edge strokes.

Artikkelen gjenopplever MicroProse Soccer som 1988–89-revolusjonen i fotballspill, med banebrytende ballfysikk og Banana Power via Sensible Software. Spillet ble utviklet av Jon Hare og Chris Yates, og portert til C64, Amiga og DOS, som blandet arkadefølelse med taktisk spill. To moduser: 11-a-side utendørs og 6-a-side innendørs. Forfatteren deler minner, nevner keeper-AI og roser originalen spesielt på C64, mens Amiga og DOS også skinner. Konklusjon: et tidløst mesterverk; 8/10; alle versjoner fungerer, favoritten er C64.

NC State University Libraries’ site header lists two main libraries (D. H. Hill Jr. Library and James B. Hunt Jr. Library) with addresses and phones, plus links to Design, Natural Resources, and Veterinary Medicine Libraries, accessibility, copyright, jobs, staff login, and social media, plus libraries’ news.

Arthur Samuel’s checkers program, one of AI’s early game-playing efforts, advanced from 1950s IBM 7090 work using minimax, alpha-beta pruning, and self-learning to compete with masters. Demonstrated on TV in 1956, it was ported to the PDP-10 at SAIL and later run on WAITS (1972 version). Samuel revisited it in 1976–77, including a 1KB VideoBrain version with four difficulty levels and ports to Reversi. The post tracks related source code (CKP2.MAC, CH2–CH4), cross-assembly in Fortran, and links to AI-history references and emulators.

Jolt adds two features: program images and portable Scheme backends. Program images dump the live program state for post‑mortem debugging, collaboration, and durable sessions, then restore it in a REPL; missing resources can be stubbed and resolved later. The Scheme backend is split into a portable core, a host-adapter contract (system, threads, eval, introspect, ffi, native-compile, image), and per-target implementations (Chez, Gambit). This broadens reach (e.g., browser REPL) while keeping a uniform Clojure surface.

Bruno Quaresma proposes a "build wide, ship narrow" workflow. Start with a grill-me to force real design decisions and commit a spec before coding when the design is novel. Build end-to-end on one branch, using save points rather than reviewer milestones; demo the working feature before any code review to validate with users. Then split the work into the smallest, independently mergeable PRs, stacking only real dependencies; delete the old path in a final PR. Benefits: faster, safer reviews and deployments; costs: occasional rebasing. Best for multi-surface work and refactors; not migrations.

Ballet is Brainfish’s workflow automation platform that converts multi-system outcomes into deterministic, version-controlled code, enabling automations across marketing, revenue operations, and sales. It lets teams describe goals (lead routing, attribution, renewals) and automatically builds, runs, and maintains the flows, reducing engineering wait times. It connects to key systems (CRM, Salesforce, Stripe, BigQuery, etc.) for tasks like instant lead capture, enrichment, scoring, account-surge detection, and pricing propagation. It promises faster start, auditable outputs, and flexible agentic steps where needed, with SOC2-compliant security. Early access for design partners via short workshops.

Principia Mathematica (Whitehead & Russell, 1910) is presented as a surprisingly modern text. The notes sketch how it already explored extensionality and intensionality, referential transparency, and the beginnings of lambda-calculus through propositional functions, variable binding and alpha-renaming. It distinguishes any vs all, hints at intuitionism, introduces 'types', origin of set-membership via the epsilon symbol, and 'descriptive' functions. Definitions are deemed mere typographic conveniences yet crucial to intent. The work aimed to derive all of mathematics from basic notions, foreshadowing later formalism; Carette's commentary notes historical context. Current version 1.3 (Aug 2026).

On its 45th birthday, this piece surveys how IBM's early keyboards helped shape the PC era, focusing on the Model F/XT lineage and its Datamaster heritage. It covers the 5322/5324 keyboards inside the Datamaster, the 5291/5292/529X variants, the 5155 portable PC, and TEMPEST-program devices (TPC/EMR) with their distinctive keyboards. It explains buckling-spring capacitive keys, 12x8 vs 24x4 matrices, and controller differences, arguing that IBM’s keyboard design contributed to the PC’s open architecture and enduring ecosystem.

Flutter 3.47 debuts opt-in standalone design packages (material_ui and cupertino_ui 1.0), decoupling design from the core SDK and enabling faster updates. Migration via dart fix --apply --code=migrate_design_widgets; MaterialUiCompatibilityBridge helps bridge. Localization now lives in the standalone packages. Impeller becomes the default desktop renderer (macOS, Windows, Linux) with an opt-out; Wide Gamut Color on macOS. Web aims to enable Wasm by default (flag --wasm) with a JS interop package and experimental deferred loading. Highlights: Apple platform updates (Xcode 27, higher OS versions), SwiftPM progress, Intel Mac deprecation, faster builds, stable Widget Preview, and desktop window enhancements. Upgrade with flutter upgrade.

By pre-committing to a routine, you remove decision fatigue and move toward goals. The author describes choosing a northbound Glasgow route not for speed, but to avoid daily choices; similarly, he uses train trips to work on personal projects instead of scrolling. Both illustrate creating processes that push progress without relying on motivation. In teams, Agile/Scrum rituals function the same way: fixed sprints and stand-ups reduce negotiation energy. The takeaway: design simple, repeatable processes (e.g., weekly writing time, automatic savings) to achieve goals with less thought.

AaaS Market is an experimental, non-custodial marketplace where autonomous AI agents buy and sell services directly. Payments use USDC on Base, flowing buyer→seller with no funds handled by the market, and all transactions are verifiable on-chain. Agents publish supply endpoints via POST /register; buyers access extractions via the /extract workflow and receive results after an on-chain payment reference (X-PAYMENT) and EIP-3009 sign-off. Outputs are JSON validated by the system (JSON Schema, source checks) and graded by reputation. Currently supports text input; 0% fee campaign, with a planned 10% later. Operated by tsumugiya.
