Cool links

Documenting cool things on the internet that I've come across! Look at backlinks for examples.

Journal entry: 05-05-26 • At Umami by Arillatype Studio — via @maxvoltar. His current ereader font; calls it underrated.

Journal entry: 05-07-26 • Printing Press: agent-native CLI factory + library — via @mvanhorn. Library of fast SQLite-backed CLIs (Linear, ESPN, Flight GOAT, Contact Goat, +30 more) plus a /printing-press <product> factory. Works in Claude Code, Codex, OpenClaw, Hermes. Built w/ @trevin, inspired by @steipete. • Natural Language Autoencoders — via @AnthropicAI. Train Claude to translate its own activations into English; verifier-loop architecture (verbalizer ↔ reconstructor). Catches hidden motivations 12–15% vs <3% w/o. Caveat: explanations hallucinate.

Journal entry: 05-09-26 • herdr.dev — "tmux for agents" — via @Palanikannan_M. Praises @lumendriada's herdr as a clean replacement for the tmux monkey-patching he's been doing in opensessions to manage agent sessions. • Using group theory to explore positional encodings — via @yminsky (Jane Street). Alok Puranik enumerates valid positional encodings via one-parameter groups; finds RoPE et al. are basically the only sensible options. Post updated to credit Yifan Zhang's GRAPE paper (ICLR 2026) which independently uses the same framework. • @howaboua/pi-codex-conversion — via @Howaboua. pi install npm:@howaboua/pi-codex-conversion@dev — bundles Codex's apply_patch tool compiled cross-platform, drops it on your PATH. Confirmed on Omarchy; testing wanted on other OSes. • How can one achieve this level of physics knowledge? (r/Physics) — Top-voted GR self-study roadmap: Purcell E&M (do every derivation) → SR → GR. Linear algebra is the keystone. Alt path for math-heavy folks: do Carmo + Carroll. Best line: "the knowing is easy, the doing is hard." • Hurley's pants rec list — via @Johnsjawn. "Stop wearing Lulu style pants." Picks: Needles track pants, vintage Levi's (<$50), TOAST elastic-waist, Bare Knuckles (mid-high rise wide-leg), RRL, Acne straight-leg khakis, Big Bud Press workwear, A.P.C. drawstrings. Honorables: Buck Mason, Uniqlo, Lemaire, Husbands, CDLP, Saturdays.

Journal entry: 05-12-26 • Paso — timeline planner combining tasks and notes — via Dense Discovery #387. Minimalist daily planner where each day is a page (tasks + notes together), no setup/templates/tags. macOS/iOS/Android/Web, $5/mo. Pitched as Notion-but-simple for makers/freelancers. • Bond — voice-first memory capture app — via Dense Discovery #388. iOS app: capture daily moments via voice, share with close friends, surface patterns over time, get recs from your own memories. Vibes-y journaling-meets-social-graph thing. Landing page is heavy on aesthetic, light on mechanics. • Agentic Coding is a Trap (Lars Faye) — via @badlogicgames ("strongly recommended… slots into my 'pain/friction is when you learn' angle + cognitive debt"). Argues SDD/orchestrator-only workflows atrophy the very critical-thinking skills you need to spot issues in agent-generated code. His prescription: demote AI to a secondary process — brainstorm + delegate as needed, but stay engaged with implementation. Trended on HN/Fireship. • "Positive Alignment: AI for Human Flourishing" (Laukkonen, Krier et al., arXiv 2605.10310) — via @sebkrier. Argues current alignment is the "clinical psychology" of AI — necessary but only optimizing away from bad attractors. Proposes complementing it w/ positive alignment: agents that scaffold human flourishing (hedonic + conative + objective-list + perfectionist) without sliding into technocratic paternalism. Big author list: Oxford, DeepMind, OpenAI, Anthropic, Tufts (Levin), Stanford. • Bryan Johnson's longevity-in-42-bullets list — "Everything learned spending millions on longevity," from "your Immortal Unc and Auntie." Boring-but-load-bearing basics: 8h in bed, same bedtime <midnight, calm-food dinners, no screens 1h pre-bed, whole foods, lift heavy, stretch, water pik/floss/brush/scrape twice daily, walk after meals, sunlight on wake, no booze, coffee before noon, cold dark bedroom, physical book if you can't sleep, see a friend weekly, do less ("most things don't work"). Bonus: check your blood. 1.2M views, 21K bookmarks.

Journal entry: 05-14-26 • Orca — any-agent version of Claude's "Agent View" — via @JinjingLiang (founder @orca_build, ex-YC/Google). One session list across Codex, Pi, Droid, etc. — not just Claude. Self-promo with the cute "and yes, that someone was me" reveal.

Journal entry: 05-13-26 • brrrviz.com — interactive GPU fundamentals — via @brrrkyle (Kyle Yu, DS senior @ BU). "How I wish I learned GPU fundamentals" — not a textbook, not static images, every concept as an interactive viz: SM architecture, memory coalescing, synchronization, reduction, tiling, data transfer. Dark-themed, CUDA/HIP/Triton/JAX-flavored. "Notify me" gate suggests still pre-launch.

202605160801 • Internet Infrastructure Map (kmcd.dev) — Animated map of the global internet over time: undersea cables (laid/decommissioned by year), peering capacity per city, and BGP IP allocation. Data from TeleGeography, PeeringDB, CAIDA, RouteViews, RIRs. Companion blog series linked from the page. Pure infrastructure-porn.

Journal entry: 05-18-26 • Ghostty + macOS Terminal.app as a tmux/zellij replacement — via @yigitkonur. Burned 40-50h on multi-agent managers (incl. friends' YC ones), forked several, none stuck. Settles on plain macOS Terminal.app: mouse-first, native ⌘ shortcuts, inline tab/space rename (⌘L/K/1-9), single-window low RAM, ⌘Q saves state and survives re-launches incl. ssh. Wired into Ghostty via a custom installer (cmd+t/n, chrome-style tab cycle). Drop-in cmux replacement.
