Blocking disposable email domains at signup increasingly punishes privacy-conscious users while doing little against motivated abusers.
What I noticed about commit ownership drifting across packages, triggers, scripts, and clients — in one horribly complex system I help maintain

I added Souls-like comments to my blog
Praise the stakeholder! This is what happens when you mix the chaotic, creative energy of Dark Souls messages with technical and corporate jargon.
ChatGPT Work is an agent that can take action across your apps and files, stay with a project for hours if needed, and turn a goal into finished work.
Stop Lying to Your Cofounder
It’s sprint review. A team “pulls out” work finished a couple of weeks ago, presented as fresh. Everyone in the room half-knows. That’s how teams deteriorate fast, and startups become political. Le…
Process is one of those topics that reliably creates tension in growing engineering organizations. Too little of it and everything feels chaotic. Too much of it and nothing moves. Most teams I work with aren’t confused about whether process matters. They’re st…
How to Be a Good Open Source Maintainer
Most open source runs on one unpaid maintainer, and the silent close is the default. How to build a project that answers contributors on your worst week.
A concise, visual retelling of Jay Kreps’ classic essay on the log — the unifying abstraction behind databases, distributed systems, and real-time data.
A little story from debugging performance issues lately
Ok that’s a bit of an exaggeration. It’s not that I don’t like defer, I think I might just prefer something else. But I’m not sure why. In this blog post we’ll take a look defer and its alternatives, and hopefully I’ll come out with a better idea of my own pre…
AI looks like the great equalizer. The rookies got better, the gap closed, the floor came up. I think that read is exactly backwards, and it falls apart the moment you stop staring at one slice of the picture and look at the whole curve.
The most successful machine of the eighteenth century was a cabinet with a person inside. Much of the AI stack still is.
Prose Isn't Policy: Stop Writing CLAUDE.md Rules
A CLAUDE.md rule is a wish a probabilistic model might honor. A lint rule is a law it can't merge past. When agents ship more code than you can review, stop documenting your conventions and start enforcing them.
Design a distributed unique id generator
We need to create a unique ID generator for our high-traffic web application, generating about 10K IDs/second. The IDs can't simply be monotonically increasing integers, which are good for data access
If you gave everyone an intern, would your team be more efficient? For anyone who has either been an intern or had an intern, I think the answer is emphatically and obviously no. There are many reasons to hire an intern, but speaking from my experience as a on…
Entrepreneurs Capture the In-Between
The word entrepreneur comes from the French word entreprendre. “Entre” means between, and “prendre” means to take, so literally it means “to take between.” It refers to recognizing and capturing an opportunity that exists between two things.
🎉 Hy3 is available for everyone
One AI assistant is a tool you drive. A fleet of agents working unattended is a management problem: an inbox, approval gates, written rules, and a weekly cadence. Lessons from running a real business this way.
poppy the training box, part 1: the beginnings
Repurposing an old SFF PC as a dedicated LLM training box: a second-hand RTX 3090, an accidental 11-day train on a GTX 1660, and one dead CPU fan.
More intelligence from every token, stronger performance per dollar, and more capability on demand for your hardest work.

EU Parliament greenlights Chat Control 1.0 – Breyer: "Our children lose out"
Today, the European Parliament allowed the suspicionless mass scanning of private communications ("Chat Control 1.0") to pass, a measure it had rejected twice in March. Although a majority of voting Members of the European Parliament (MEPs) actually opposed th…

Today, we’re launching SWE-1.7, the most capable model we’ve trained so far. It reaches frontier-level intelligence at a much lower cost, advancing the cost-performance Pareto curve.
