What you get

New essays from the writing archive — a summary in the email and a link to the full piece on the site: working notes on what cloud and AI infrastructure actually cost, where the economics stop behaving the way the architecture diagram implies, and what that means for the people who have to run it.

This is a personal publication. Nothing in it represents an employer's position, roadmap or product view.

If you want a sense of the range before handing over an address, the strategy insights go deeper on the same themes, and several carry calculators you can run against your own numbers.

How often

New essays are what the list sends, and it sends nothing else. There is no schedule and no minimum: May 2026 had nothing in it at all. The writing archive is the honest record of what that has meant, and it will tell you more than a rate quoted here.

Nothing is sent between essays: no round-ups, and no re-sends to people who didn't open the last one.

What happens when you subscribe

The list runs on Buttondown (opens in a new tab) and is double opt-in. Entering your address sends you a confirmation email; you are not subscribed until you click the link in it. There is no other field to fill in.

Your address is used to send you the newsletter. Buttondown records whether an email was opened and whether a link in it was clicked — that is what makes the no-re-send rule above possible — and the address is not sold, shared, or put on any other list. Every email carries an unsubscribe link and it works immediately. The newsletter section of the privacy notice sets out what is collected, who processes it and how to have it deleted.

You can follow it without subscribing

Email is not the only way. The writing feed carries every essay and asks for no address at all. The full site feed adds media appearances and the strategy insights, and llms.txt is the content map for anything pointing a tool at the site rather than reading it.
