title: One Config, Parallel Agents, and Cursed Fonts
date: 2026-09-29T18:00:00.000+02:00
week_number: 40
notes: "**TL;DR:** This week has tools for coordinating agents, streaming useful results sooner, and handling concurrent edits, plus practical accessibility lessons, critical CSS, a distinctive UI kit, and some questionable font science."

    url: https://noti.st/matuzo/OD53aV/slides
    comment: "Manuel Matuzovic's slides go past the usual alt-text checklist: fixed headers can eat the viewport at high zoom, and `aria-haspopup=\"true\"` tells assistive tech a navigation is a menu. The popover examples are useful too."

  - title: Faster SSE Responses with Async Generators and Promise.race()
    url: https://thecodebarbarian.com/sse-yield-star.html
    comment: Two database queries can start together, then `yield*` an async generator to stream whichever result arrives first. That gets useful data to the client without making it wait for `Promise.all()` to finish.

  - title: How Notion Handles Concurrent Editing with CRDTs

    comment: The awkward case is one person splitting a block while another edits the text that moves. Notion's text-slice IDs and search labels help locate the edit after the split, a useful look at the production details behind CRDTs.

  - title: Animal Island UI
    url: https://guokaigdg.github.io/animal-island-ui/#/
    comment: Animal Crossing's cosy island look—warm colors, pill shapes, chunky game-like buttons, and motion—gives this React component library a clear visual direction. I can see it making a small app feel delightfully odd.

  - title: Critical

    comment: Critical finds the CSS needed for above-the-fold content, inlines it, and defers the rest. A fast static path handles prerendered pages; Playwright is optional when a page needs a real browser render.

    comment: Bastardica combines fonts into one hybrid typeface, with plenty of room to make a readable face look subtly wrong. This is the sort of tool that can make a whole team question their eyes. Great idea for the April's fools day.

  - title: Superdiff
    url: https://github.com/DoneDeal0/superdiff
    comment: Superdiff compares nested objects and text, and can stream or read files for larger inputs. It gives you a structured diff to inspect instead of making you squint at two giant serialized JSON blobs.

  - title: metaharness
    url: https://github.com/srsatt/metaharness
    comment: I'm building this to keep one config for several AI agent harnesses and their providers. The idea is a single place to manage which tools and backends a project should use as the options keep multiplying.

    comment: Orca runs coding agents side by side in isolated worktrees, with terminals, diffs, a browser, and tasks in one app. The coordination layer looks more useful than another wrapper around a single model.

  - title: Ternary Bonsai 2 27B — GGUF
    url: https://huggingface.co/prism-ml/Ternary-Bonsai-2-27B-gguf
    comment: Prism ML lists a 5.95 GB language-model pack and reports 98.2% of FP16's score across 14 thinking benchmarks. The size is for the model weights alone; the score is the project's benchmark average, not a universal quality guarantee.

My favorite is Bastardica: typography could use more tools that make you ask, “Is this broken, or am I going crazy?”
