it sped up iteration speed many, many times, and the teams that did agile (not capital A) got to CD amusingly quickly - from the state of shipping software 1-2x per year (seen that)

Brought to you by WorkOS – fresh from the WorkOS oven: Airlock, the authorization layer for AI agents. It evaluates every request against the agent’s intent and your rules and either allows it, denies it, or routes it to a human for approval. Works w CC, Codex and MCP gateways. workos.com/airlock

Airlock — WorkOS

Airlock is the missing authorization layer for agentic software. Every call an agent makes is evaluated against its intent and then allowed, denied, or sent to a human.

Peter Mattis has quite the history in shipping large-scale, production sw: he created GIMP, built Gmail’s original backend, shipped Google’s Colossus distributed backend stroage system, and is the cofounder and CTO at Cockroach Labs, the makers of CockroachDB. A convo on distributed DBs: (cont'd)

The last time building software sped up ~10x (early 2000s, the agile movement), a massive interest in automated testing followed almost immediately (unit tests, TDD, XP etc) Today, building software sped up 10x, easily: and a similar massive interest in automated testing + verification is following

Very much enjoying this “GPU glossary” mini-book by Modal I got from Can Duruk when stopping by at Modal’s NYC office. I don’t know if the physical books can be purchased, but the book has an online version, as I learned; with the same contents: modal.com/gpu-glossary

Oh WOW. I was going through my "outdated" (aka old) books and look what I found: the TypeScript book I bought in 2019 to get up to speed with the language. Only now realizing who the author is: Boris Cherny, widely known as the creator of Claude Code. Was a great writer + educator before :)

"Application development did not change much for 20 years, but now, a new wave is crashing in. Most computers in the future must be put to work at least in part w/o programmers. Not surprisingly, programmers will instinctively resist methods described in this book." - 1982, James Martin (cont'd)

A look into how the Windows team is integrating AI into their OS: eg adding agent identities, akin to that of a user. It's the first opinionated approach I see for AI agents at the OS level - and surely other OSes will do sg similar. Deepdive: newsletter.pragmaticengineer.com/p/windows-an...

Fresh data from GitHub: Agent-generated PRs have exploded in size. 9x the last 8 months (!!) No signs of slowing down. This is why everyone is rethinking code reviews, deploys, possibly even o11y thanks to the GH team for sharing this data with me! (Slide from my talk yesterday)

So no, I'm not particularly excited about Fable 5.1 or Astra or anything else - what would I use it for?? The fact that Astra demos are all about recreating old games in web browsers suggests to me people also have no idea what to use these new models for save for copying existing software tbh

Gergely Orosz @gergely.pragmaticengineer.com · 08/09/2026

I have to admit, I have zero excitement about this latest flurry of new model releases I am sure they are all better, but the existing ones were more than good enough, and I'm learning how much to trust those existing ones... and already they do more than I can utilize them (for writing code)

the modern engineering behind Revolut, Monzo, Ramp, Mercury, Stripe: all banks or fintechs, no 4-8 hour downtimes every other week GitHub is embarrassing themselves, we know, I have analyzed it in detail: blog.pragmaticengineer.com/the-pulse-ai...

The Pulse: AI load breaks GitHub – why not other vendors?

GitHub’s leadership blames the 3.5x increase in service load as the cause of degradation – or it might be self-inflicted.

Gergely Orosz @gergely.pragmaticengineer.com · 02/09/2026

Still find it so wild that SO MANY European banks schedule 1-2x per month 4-8 hour maintenance windows between 10pm-6am local time. INSTEAD of biting the bullet and learning how to do zero downtime migrations & infra upgrades Devs pull all-nighters instead + learn nothing about modern engineering

Just heard: Meta is moving from GChat (Google's Chat product) to Slack, because... Slack has much better agent interoperability (true) Who thought AI+agents would be a big selling point for Slack? Or that Google would sleep on agents + GChat! Or that Meta used GChat, deprecating Workchat…
