LLMs got good at code because it's verifiable. Operations isn't, so manufacture the reward by simulating production, the way robotics learns in simulation before reality. The catch: the model only ever covers the failures you already understood. www.dajobe.org/blog/2026/06...

New blog post: Sovereignty as an SRE problem. Three years on Google Cloud Dedicated, operated by S3NS in France. The political ask of "sovereignty" breaks down operationally into three intertwined SRE questions: SLA, staffing and complexity. www.dajobe.org/blog/2026/05...

Coding LLMs spread because public code spread. Production engineering data is private by default, so AI-for-ops concentrates around whoever has it. The data plane matters more than the model. AI for Production Engineering: Who Gets to Build It www.dajobe.org/blog/2026/05...

Why LLMs work for code but struggle with systems: code is verifiable. Production engineering depends on live state. Same change, different outcome. The Verifiability Gap in Production Engineering www.dajobe.org/blog/2026/05...

A file is a table. A line is a row. `comm -12` is intersection, `comm -23` is set difference, `join` is an inner join, `sort -u` is DISTINCT, `sort | uniq -c` is GROUP BY + COUNT. A line-oriented relational algebra hiding inside POSIX: www.dajobe.org/blog/2026/05...

Fleet automation lesson four years on: the caps on your destructive operations bound count. They don't bound concentration. Sorted host lists correlate with physical topology, and 'head -n 5' will cheerfully take out a rack. www.dajobe.org/blog/2026/04...

Today I started work as a Senior Staff Production Engineer at Crusoe AI in SF. www.dajobe.org/blog/2026/04...

At this point we need a language model solely trained on Claude Code product releases.

Going out for a walk and lunch. /remote-control and continue working. #claude

Made my second viewing for IMAX Project Hail Mary. I highly recommend the film and IMAX and the creators and the stars.

Good news everybody $DJT all time low. I'm confident he can do better, I'm sure he can collapse it to $0. He'll have to make it up with bribe jets and crypto scams.

I wrote up how I manage dotfiles in my homelab with zero dependencies. No frameworks, installers or runtime requirements. Uses git and shell scripts so I can easily setup machines and manage them. The goal: simple, predictable configs that work everywhere. www.dajobe.org/blog/2026/03...

Eight coding LLM tools, one configuration. Same prompts, same workflow, different models on demand. The harness layer matters more than the model. www.dajobe.org/blog/2026/03...

I was going to write a post about how LLM based coding has changed the software interview process in 2026... but it hasn't. Over the 15+ interviews so far, it barely came up. Maybe it's due to the level I'm aiming at. My one pro tip: learn @excalidraw.com keyboard shortcuts.

I’ve spent the last 9+ months using AI coding tools heavily and I have thoughts: • The harness is becoming more important than the model • Agents are mostly code-writing loops with tools • Code might be becoming the new assembler www.dajobe.org/blog/2026/03...

What's the latest on Operation Epstein Fury? Did the objective of distracting everyone work?

Looks like somebody’s going to have to give back their FIFA peace prize.

At a weird stage of LLM stuff today. I caught Claude Code out and got it to admit failure and then asked it “how can I prevent you doing this in future?“ It's answer: How to Prevent Me From Disobeying in Future

SCOOP: Business leaders are paying as much as $5,000,000 to meet one-on-one with President Donald Trump at his Florida compound, sources tell WIRED, while others are paying $1,000,000 apiece to dine with him in a group setting.

Strong rumor with credible sourcing: DOJ has put all of public integrity line attorneys in a room and told them they have an hour for someone to choose who will sign motion to dismiss and if nobody does, they will all be fired. The nastiest strong-arming in DOJ history by a long shot.

DOJ leadership has put all Public Integrity Section lawyers into a room with 1 hour to decide who will dismiss Adams indictment or else all will be fired. Sending them strength to stand by their oath, which is to support the Constitution, not the president’s political agenda. 🇺🇸

Yes, this administration is dangerous and cruel, but they are also shockingly dim and incompetent. Opportunities are everywhere. Make everything as hard as possible. Resist every demand. Refuse entry without a warrant. Don’t take the buyout. Their problem solving skills are 📉
