it's built-in to the tool, you create a rules/ directory and fill it with these yaml-formatted rule definitions ast-grep.github.io/guide/rule-c...

id: yieldable-errors message: Directly yield errors instead of wrapping them severity: error language: tsx files: - app/*/*.ts - server/*/*.ts - app/*/*.tsx rule: pattern: yield* Effect.fail(new $A($B)) fix: yield* new $A($B)

another refactoring done efficiently with ast-grep in a way that can be enforced forever ❤️

haha, sorry - I saw your talk! Should have said hi

speak for yourself, i've been hitting the gym

great work hosting! sorry i didn't swing by to say hi during the thing

the good: pretty easy to make super lightweight components with inline css and js. a+ for speed-obsessed web dev.
the bad: super super hard to learn, very easy to mess up, generally quite bad error messages.

In the Atmosphere A lot of nice people in Vancouver talking about nerd stuff

under the hood, been using webc for a few things on my blog, for the @observablehq.com plot chart on macwright.com/2026/04/05/i..., the theme selector, and youtube embeds.

i'd say it's 2/10 DX, 9/10 magic, technology that fills me with both joy and fear www.11ty.dev/docs/languag...

In the Atmosphere A lot of nice people in Vancouver talking about nerd stuff

finally posted thoughts about the atmosphere conf (along with an illustration and a bunch of tweaks to the blog) macwright.com/2026/04/05/i...

mode.js GitHub Gist: instantly share code, notes, and snippets.

just to serve mode.css to do light/dark/auto theme switching without having to put js on every page :/ it's super tiny but alas gist.github.com/tmcw/2015bda...

the same watercolor, on a scanner

it's satisfyingly large art irl, too

watercolor illustration

illo for an article i'm trying to publish. been in writing/editing/watercoloring/making-a-chart mode for three hours unexpectedly tonight. felt good to get in a ""flow state"", though the article still isn't what i want it to be.

ai agents filling out quarterly 360 reviews

stack-ranking subagents

doing bigger watercolors is better because you spend more time putting the paint on the paper

dark mode has been slowing my website down by more than a hundred ms 👿. netlify edge functions: not as fast as i'd hoped.

i really liked their original product but it ended up being kind of like replay.io, amazing tech that people don't value.

the all-time startup pivot champion is quirk i think

a weird thing in my @obsidian.md vault: a note that keeps track of all the startup pivots i see

i think it’s going / they achieved a bunch of stuff - @schuyler.info is one of the main folks

i haven't because i'm fastmail 4 lyfe, but it's probably pretty good in the specific ways that most 37signals stuff is

A delightfully fresh take on email + calendar, from 37signals Gmail, Outlook, and Apple got complacent and took their eye off the ball. Then along came HEY.

this is kind of what hey.com does - new emails always go into a screener instead of your 'imbox'

Protomaps The open source map for developers

oh, and to deliver that data aesthetically and cheaply, protomaps has basically solved that problem, anyone can get great looking maps for very little $ protomaps.com

openstreetmap's hiking trail coverage is pretty decent, strava has been backing their updates into it for years because they use mapbox so that's where their map data comes from.

i bet 'alltrails' is the next thing to be rebuilt on atproto if it hasn't already

sure, i guess my personal prejudice is that i love everything that isn't natural language for creation and despite the manager-employee dialog that vibecoding operates on

sure, i didn't mean to do a descartes, we have to affect the world, but i don't think that the mediums of guitar/painting/writing/etc are similar to the medium of llms

when beginners fail at painting or guitar, they sometimes blame the materials but mostly are aware that they need to become better. when people fail at vibecoding, they are just disappointed that the artificial intelligence product cannot translate their vague thoughts into concrete representation.

being alone with your thoughts and struggling to produce an output is kind of the polar opposite of trying to produce an output by begging an all-powerful god to do it.

aesthetically, if it matters, seeing vibecoding workflows firsthand, the struggle of creation takes the form of begging, whining, arguing, more like a supplicant than a creator. it looks and feels pathetic, and when it is paired with a disinterest in learning, i think it is

the arc from "popular software with the worst code quality i've ever seen" to "seeing that software in subway ads" is unstoppable recently
