Link Diary June 2026

Started in a backyard in 2020 and is now Louisiana's largest glass recycler. The waste glass is turned into sand to rebuild the state's disappearing wetlands.

Anyone booking an expensive room is renting from a brand that often no longer owns the hotel. Henning Laakmann explains how hotel chains work through franchising, timeshares, and management contracts, and why the brand name is worth more than the property.

A medical student built his own spaced-repetition system and used it for 17 years, almost without traditional cramming. It makes you think about what continuous micro-repetition can really achieve.

A practical test of whether an Ollama agent on a laptop can do real assistant work: an email-triage pipeline instead of a demo hello world. Very practical, with clear Python examples.

What really happens between browser and backend? The channel cleanly breaks down the gateway layers: who terminates TLS, who distributes load, who routes, and why these are three different roles rather than one.

The author goes from 20 to almost 100 repetitions per set in 10 weeks. No fancy equipment, no sets to failure, just a specific protocol originally developed in the Soviet Union.

What if the reason for belly fat is not diet or exercise, but the first hour after waking up? Five simple, scientifically supported morning routines from everyday Japanese life, especially relevant to cortisol.

An extreme clean-up of an apartment crawling with cockroaches. Purely cathartic and highly visual, with explanations of professional pest control along the way.

Eight electrical appliances perform the hit: an epilator, two toothbrushes, three credit-card machines, and two typewriters. Pure ASMR music, a perfect 1:49 for a quick break.

A 34-minute cleaning video from the channel *Midwest Magic Cleaning*. The title is deliberately exaggerated; the video itself is a normal deep-clean run.

Google announced the *Open Knowledge Format*: a new standard that structures knowledge in simple Markdown so agents can read and use it. Marie Haynes explains the SEO implications, shows how to build the first OKF bundle, and presents workflows for your own data.

In underwater films, the open pool in the floor of a habitat station is a standard feature. But is it real engineering? Using Aquarius Reef Base, the world's only continuously operated underwater research laboratory, Ian explains how such an opening works and what saturation divers have to consider.

A complete upload of the animated series based on Angela Sommer-Bodenburg's children's books, featuring Gerd Fröbe from *Goldfinger*. Nostalgia for a rainy weekend.

Marina Wyss summarizes Chip Huyen's standard work *AI Engineering* in 76 minutes: foundation models, evaluation, model selection, prompt engineering, RAG, agents, and fine-tuning. A good overview for anyone who needs the material but will not read the book.

ForrestKnight pits a frontier model against a local LLM on real TypeScript and Rust codebases, and the local model performs surprisingly well. A practical benchmark without the marketing fluff.

Ruri Ohama collects seven unconventional strategies from everyday life with ADHD, beyond the usual “just use more discipline” advice. Includes a sponsor segment for a desk speaker, but the hacks stand on their own.

Good Games Brewing recreates the main theme from *Pirates of the Caribbean* using the in-game recorder flutes from Stardew Valley, including changes in time signature. Two minutes of pure listening pleasure.

Renée Ostertag demonstrates a short exercise that uses eye and head position to give the brain a safety signal and move toward a calmer state through yawning, sighing, or swallowing. The channel explicitly states that this is not medical advice.

Since Terraform 1.6, the test framework has been generally available. Ned in the Cloud shows how to write unit and integration tests for Terraform modules, including syntax, setup, and best practices.

A short piece about Godot migration among indie developers. Most of the video is actually the channel's devlog for a hand-drawn 2D roguelite in Godot; the “why switch?” question is mainly the hook.
