Postgres Says "Too Many Clients Already": Diagnose It Before You Add a Pooler

FATAL: sorry, too many clients already almost never means your database is out of capacity. It means something in your stack opened more connections than max_connections allows — usually a per-process pool multiplied by more processes than you remembered running, or connections parked in idle in transaction. Adding PgBouncer fixes the symptom, but if you install it without finding the multiplier f...

Your dog's camera roll is a wellness history. BarkPass makes it speak.

Your dog's camera roll is a wellness history. BarkPass makes it speak.

This is a submission for Weekend Challenge: Dog Days Edition. Dog owners take hundreds of photos and then rely on memory for the question that matters: has anything changed? Yesterday's posture, last week's energy, that unusually restless look—each clue is visible for a moment and then buried between screenshots and receipts. BarkPass makes the camera roll queryable. One daily photo becomes a s...

Bot timing has an entropy signature, and you can measure it on live Nostr data

I have been poking at a question that sounds simple but turns out to have a real answer: can you tell a bot from a human just by when they post, ignoring everything they actually say? Turns out you can, mostly. And you can measure it against live Nostr relays in an afternoon. Here is what I found, including the case where it falls apart. The idea: gaps, not timestamps A person does no...

Is there any other JS REST API framework that is secure by default, plus OpenAPI support like FastAPI, runtime-agnostic like Hono, Contract-first api like Elysia & TS-rest, and scoped plugins like Fastify?

The Twenty-Hour Fuse

Two nights of debugging, one incident left to write about. The night of August 14th, a Claude Code session hung for an hour inside the VS Code extension, and I traced it to a per-token streaming stall — the previous two pieces cover that hunt and the middleware that fixed it. The morning after, the same four-core box nearly went down under a load average of 38.7, and it turned out to be the same i...

No Jinja: What Replaces Templating When SQL Is an AST

Interlace has no templating language. A model is a .sql file containing SQL, or a .py file containing a function. There is no {{ }} and no {% %}. Updated August 2026: Interlace has since gained macros — as SQL expressions expanded into the AST, not as templates. Job three below is rewritten to match; see A Macro Is an Expression, Not a Template. The reasonable first reaction is that we have simp...

Coalescing the Stream

Claude Code, on my box, doesn't talk to a model provider directly. It goes through claude-code-router (ccr) — a self-hosted proxy that lets the same CLI point at the official Anthropic API or at third-party providers — and I watch the whole thing through the VS Code extension over Remote-SSH. The previous piece, Two Clocks, Neither Lying, worked out why that path once let an approval prompt sit fo...

Two Clocks, Neither Lying

The night of August 14th, Claude Code was planning me a trip. An eight-day itinerary — not code, just travel planning — running in the VS Code extension against the remote box where my sessions live. Just past midnight my phone buzzed: the turn had finished, and Claude was waiting for me to approve its plan. That buzz was claude-code-notify, a hook I wrote myself so that a long turn, or one waitin...

I open-sourced a tiny PHP library that turns a photo into a Pinterest pin.

SyndiKit Pin SyndiKit Pin is a small, focused PHP library for generating Pinterest pins in code. Give it a photo and a headline, and it renders a clean 1000x1500 pin: the photo fills the top, an accent bar divides the frame, and the title sits on a readable panel with an optional brand line. It also renders a 1.91:1 image for Open Graph and Twitter cards. It uses nothing but PHP and the GD extens...

Twenty-Five Million Rows in Five Seconds, and How to Check

Benchmarks in this industry are mostly untrustworthy, and usually for the same reason: the person running them chose the shape of the work. So let us be precise about what this is and what it is not. This is not a comparison against dbt. dbt is not an execution engine — it generates SQL and hands it to your warehouse — so "Interlace versus dbt" would be measuring DuckDB against whatever you point...
