I used to think the hard part was having something to say. It isn’t. The hard part is the forty minutes between deciding to write and actually writing — the tab-switching, the theme-fiddling, the low hum of a tool asking to be configured.
A blog is a place to think out loud on a schedule you set yourself.
So I stopped improving the setup. One page, one cursor, one button that says publish
No theme marketplace, no build step, no deploy. The distance between an idea and a published page is about ninety seconds.
Pick a name, check the address, and you have a live blog. No templates to choose, no install, no server to point at anything.
You can change any of this later.
Free to start. No card needed.
Type. Format from the toolbar or with Markdown shortcuts. Every change is saved as you go, and nothing loads while you think.
In January I cancelled every alert on my phone and replaced them with a single rule: if something matters, I’ll hear about it twice.
What I got back wasn’t time, exactly. It was the particular kind of attention that lets a sentence finish itself.

One button. Your post is online straight away, and your email subscribers hear about it a few minutes later — long enough to unpublish if you spot a typo.
Essays about attention, mostly.

Codomain is deliberately small. Each of these earns its place by removing a decision you would otherwise have to make.
Coming next: custom domains, RSS feeds, image uploads, post scheduling, Markdown export.
Four sketches of what a Codomain blog can be — an essay blog, an engineer's notebook, a recipe box, a photo journal. Illustrations, not real sites.
The year I stopped reading the news
In January I cancelled every alert on my phone and replaced them with a single rule.
Our queue was slow. Our metrics were wrong.
Six weeks of chasing a p99 that did not exist, and what the flame graph finally showed.
A dal that survives a bad day
Twenty minutes, one pot, and nothing you need to shop for on the way home.
Three weeks on the Kyushu coast
Ferry timetables, borrowed rain gear, and the light at four in the afternoon.
Everything Codomain does today is included, with no card and no trial clock. Paid plans come later, for features that do not exist yet — never by taking these away.
Everything you need to get the first post out, and the hundredth.
On the way: custom domains, RSS feeds, image uploads, post scheduling, Markdown export. No ads on any plan, ever.
