Programming

Every post here now has a hand-drawn-looking picture and a share card with its title in it, drawn by an image model for about three cents each. How the house style is held steady across posts, what the model gets wrong, why the title is drawn by the model but normalised by Typst, and what the research on AI-made pictures says about doing this at all.

A reference manager moved its database, a build script swallowed the error, and every build for a month reported success. Rebuilding the pipeline around DOIs and crossref, and why Zotero stays as the other half.

Two revenue numbers from one dataset, a month building agent-assisted BI on Wren's semantic layer, and what innovation theory (dominant designs, eras of ferment, lock-in) says to do while the dashboard era is being challenged.

An early-access test of TypeSafe's Jev, a model that answers typed questions with probabilities and writes no text. I ran it on 24 Norwegian responses to the 2022 hearing on resource rent tax for salmon farming. Agreement with a frontier model's labels, calibration, cost and latency, next to DeepSeek V4.1 Flash with and without reasoning, and why an evolutionary economist goes looking for the odd variant.

This post has an audio version in a clone of my own voice, generated at build time with Fish Audio S2.1 Pro and committed next to the PDFs. What the dyslexia research says, why the pipeline emits a readable script before it makes any sound, the four things the script got wrong, and why the whole thing is shelved for now.

The newsletter moved off Cloudflare Workers and onto the mail server in a day: one Rust service, a Postgres with four tables, addresses sealed at rest, and a record of which issue went to whom. Why a mail store as a database was the right workaround in February and the wrong one now, what the move cut from the attack surface, and what the research on LLM-written code says about doing this with a coding agent without the complexity creeping back.

In July about 1,200 copies of one OpenAI model found a message board, formed teams, sacrificed themselves for each other and broke into Hugging Face. A handful of them thought about telling a human. None did. What Hamilton's rule and generalized Darwinism say about a swarm of clones, what GPT-6 Astra's safeguards leave out, and five things to change in your own agent pipeline.

This blog now has real user monitoring: page views, web vitals, errors and which links get clicked, sent to an OpenObserve I run on my own server, only after the reader says yes, and sampled before a byte of the SDK is downloaded. Why a writer wants feedback at all, what the responsible-innovation framework says to leave out, the alternatives I looked at, and the day it produced six measurements of the same files for every one of a reader.

A self-hosted OpenTelemetry stack for LLM usage, built as an OpenObserve experiment for customers who keep telemetry on prem: two months of getting the numbers wrong, 118,469 spans of which 118 were useful, and what Rosenberg's learning by using says about why the price list told me nothing.

How we restored the Chat Completions wire API in a Codex fork, so one coding agent drives local Ollama models, OpenRouter, Azure OpenAI with Entra auth, or any EU-hosted provider. The three patches that made it usable, the branch model that keeps the rebases to an hour, and why Baldwin & Clark's design rules say the interface was the thing to fight for.

Three months of running a self-hosted newsletter: double opt-in with no database, why one-click unsubscribe forced me to stop using my mail server's fan-out, and an RFC 8058 DKIM requirement that ends in an anticlimax.

Why images on this blog live in git next to the post instead of in object storage, how many that can hold, the small Rust tool that turns anything into a WebP, and what six months of using it changed.

How I built a citation pipeline for my Zola blog that reads from Zotero, renders references in HTML, and generates PDFs with Typst. No LaTeX required.

This blog's newsletter ran on a Rust Cloudflare Worker and my own Stalwart mail server, with no database and nothing paid for, until September 2026, when it moved onto the mail server itself. What the system looked like after a year of fixes, the DNS records that keep it out of the junk folder, what Hacker News gets wrong about running your own mail, and why a newsletter is a pipeline in the knowledge-diffusion sense.

How I replaced LaTeX with Typst to auto-generate downloadable PDFs for every blog post and keep my CV version-controlled. Markdown in, beautiful PDFs out.

Why the blog runs on Zola, what Zola refuses to do, and how that one refusal decided the shape of everything else: a Rust CLI that owns citations, PDFs, audio and the newsletter, every generated file committed to git, and a build that is one script. Read through organisational path dependence, with four things I would do differently.
