An archival overview of Frost Brothers Ltd, rope makers and yarn spinners, founded by John James Frost in 1790 and run by his grandson in 1905; the 1926 amalgamation into British Ropes ended the East End rope industry, now remembered mainly through a Bishopsgate Institute publication. The piece catalogues the factory's operations on Commercial Road near Cable Street, detailing Manila hemp processing—from hand spinning, dressing, and carding to tow, winding and ground rope production—along with extensive machinery, a 1905 naval exhibition display, and views of the factory before 1860 and in 1905.

Michael McIntosh recounts his March–April 2025 slide into homelessness in San Francisco: failed shelter attempts, library refuges, and relentless bureaucratic hurdles (Dignity Moves, Human Services Agency, LifeMoves). A 94-degree screening, addiction labels, and daily grind mark his life. After a four-felony court date he represents himself and learns his grandmother has died. Denied a private room, he camps under a Redwood City bridge, cooking on a portable stove. Near a startup he once helped raise to $350M, he confronts survival amid the contrast with a nearby $140M venture.

An author shows that the interference pattern seen through a narrow gap between fingers is not classic single-slit diffraction but diffraction by a semi-infinite screen (an edge). The stripe spacing is largely independent of gap width and matches edge-diffraction predictions (Kirchhoff/Fresnel). Using nail-clippers and fluorescent light, he obtains similar stripes and estimates a period Delta x ≈ sqrt(L lambda/2), a realistic value. The effect can occur with incoherent light if the source is small. Thus the finger-gap pattern arises from edge diffraction, not simple single-slit diffraction.

Two ideas frame mechanistic interpretability: linear representations and superposition. The linear representation hypothesis says concepts are represented linearly in both embedding and unembedding spaces, with direction vectors C such that E('queen')−E('king') ≈ α E_C and U('queen')−U('king') ≈ β U_C. Park et al. find these representations are approximately isomorphic and detectable in Llama 2; orthogonality uses a causal inner product, not Euclidean. In high dimensions, superposition lets many features coexist thanks to nonlinearity (ReLU) and sparsity, with embedding geometries forming regular shapes. This framework aids interpretation and intervention in LLMs.

ROX is a clarity-first, minimal programming language that compiles to C++20. It eliminates implicit behavior—no implicit type conversions, operator overloading, hidden control flow, or exceptions. Errors are explicit values (rox_result[T]); use isOk/getValue to extract results. Core concepts: explicit types (num, num32, bool, string, list[T], dictionary[K,V]), if/else, repeat loops, and explicit list access via at(). Built-ins include print, math, and constants pi/e. ROX sources generate readable C++20 via clang++. Build with Make; run tests with the provided scripts. Status: ROX v0; future ROX++ may add modules. Web playground available.

Aim: repurpose a Xiaomi Smart Clock as a self-hosted control panel. The author compares the Chinese and global models, noting the global one’s Google integration. After hacking with MTKClient and LineageOS, backing up firmware and flashing, the device boots and works as a music player (Navidrome) with Tailscale, SystemUI Tuner, Droid-ify, and other tweaks. Potential uses include a kitchen dashboard, weather, transport, or package trackers. The clock is hard to repair, glued shut, and no longer sold; found on eBay. Prerequisites and steps are detailed via XDA forums.

Open Notes for Discord is a community-guided moderation tool that surfaces disputed claims (flashpoints) before they escalate. It scans conversations, identifies tensions, and prompts admins to invite the community to add context with AI-assisted drafting. The community reviews and votes; only notes with broad consensus are published and attached to the claim so context persists. The workflow is continuous: detect flashpoints, request notes, AI draft, community decision, context persists. The goal is to reduce moderator burnout, build trust, and enable growth without heavy-handed enforcement.

An enthusiast demonstrates hosting a website on a 25-year-old Sun Netra X1 SPARC server under OpenBSD 7.8. The setup runs httpd serving static HTML/CSS, pf with default-deny rules, and about 55 MB RAM usage. To expose the garage-hosted site safely, they use Cloudflare Tunnels (via a Proxmox LXC host) to forward to the Netra, avoiding inbound ports. The page is simple, HTML/CSS-only, with a retro aesthetic. They detail hardware tweaks (quieting fans), PXE boot, and security measures; the live site is sparc.rup12.net.

Colored Petri Nets (CPNs) extend Petri nets by letting tokens carry data, enabling guards and multi-token moves to model concurrent systems. They support verifiable correctness at build time, aiding state synchronization, deadlock avoidance, and coordinated resource use. A key example is a web-scraper scheduler: a join of available proxies, prioritized targets, and domains, with cooldowns and retries, plus a post-scrape result pipeline. Implementation paths include in-memory Rust with optional persistence or Postgres-backed transactions; partitioning strategies are needed. The author proposes building a spider-rs scraper scheduler to compare CPN approaches.

Robin Sloan's early-2026 pop-up newsletter argues that AI automation is like a flood fill that will invade digital work but cannot cross the 'magic circle' of the physical world. The magic circle, from game theory, frames activities allowed within defined constraints; computation is symbols in, symbols out. While AI can automate many digital tasks, real-world constraints (printer jams, paper, manual labor, hardware) create a firewall; ongoing negotiation redesigns tasks (sewing, olive harvesting). The author urges keeping offline systems and regulating human labor in AI-enabled physical work. The piece invites readers to reconsider work and bridges between digital and physical.

Vouch Book is a cross-repo reputation index assembled from Mitchell Hashimoto’s Vouch trust files across GitHub. Each vouch adds weight equal to ln(stars+1)+1 for the repository; denouncements subtract 60% of that weight. A user’s total score is the sum of all vouch weights minus denouncement weights, with each repo’s vouches counted separately. Data is refreshed daily from public GitHub repos; users can search and inspect vouch sources.

Martin Fowler summarizes Thoughtworks’ Future of Software Development Retreat: seniors can steer architecture with LLMs; mid-level developers face the greatest risk, while juniors may benefit from an always-on AI mentor. Cognitive debt, not just code debt, can derail teams when shared understanding erodes. DevEx and agent experience merge; IDEs should integrate LLMs and leverage deterministic refactoring. Two-pizza teams likely persist, with debates on pairing humans to drive multiple agents. Studies warn AI boosts pace but risks workload creep and burnout; managers may endure more context-switching in supervisory programming.
