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 I was going through my "outdated" (aka old) books and look what I found: the TypeScript book I bought in 2019 to get up to speed with the language.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)

That DHH saying out loud that the age of writing code by hand is over for the industry, and causing such an uproar is a bit interesting, given this was clear enough since ~January for most of us using the models + paying attention. Removed paywall: newsletter.pragmaticengineer.com/p/when-ai-wr...

I am a sucker for good books, and so especially O'Reilly books. Here's one that is WIP, but in return, it is free, thanks to @antithesis.com It's for CTOs / eng leaders who want to get AI to deliver *business value* which is... tricky. Get it here: pages.antithesis.com/oreilly-scal...

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)

Here's what OpenAI's agentic software factory looks like, today. It's surely not token efficient, but eg agents "babysitting" releases to prod is something new, and an interesting approach. Details: newsletter.pragmaticengineer.com/p/openai-sof...

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)

What’s the problem w using LLMs to write stuff you want other people to read -emails, articles, posts- and why are people (like me!) so incredibly hostile that they will block you/mute you/block your domain, to never read anything from you again? Bryan spells it out. Read it:

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

Five years ago, almost exactly to the day, I launched @pragmaticengineer.com Back then, it wasn't clear that there'd be demand for a publication written by a software engineer, for software engineers. Turns out, there was, and far more than I could have ever imagined. Thanks for your support!

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…

Well this is damning and explains SO MUCH about why Meta is losing its best engineers; why morale is rock-bottom; and why an engineering culture built up in 20 years was destroyed overnight. Zuck + execs wanted to lay off ~60% of staff. When the business does better than ever.

Hard to believe but there was a time when smoking was promoted to be healthy / harmless, even, pregnant women encouraged to smoke, 1920s-1950s. Took ~30 years (!!) to figure out how harmful it was. How long will it take to figure out the impact of AI on health, for those using it all day?

It's now the second blog post in a day sent over by an early-stage VC-startup I tried to read, but could NOT, after a few sentences. Verbose, weird... AI-generated. These companies think they made "content" more efficient. No: it's lower quality, slop +I no longer care about the startup

In 2025, it was rational to be skeptical about whether AI would change the future of software development. In 2026, it's not, anymore: We talked about this with @charity.wtf, one of my favorite voices in tech. We get into a LOT of things: • YouTube: www.youtube.com/watch?v=HC8T... (cont'd)

What I'm hearing from ~3 such stories: Meta went too far firing people. They are now doing MASSIVE counter-offers like to those handing in resignations. Some accept it, most just use it for more $$ at New Job, desperate to get out. It was such a predictable outcome btw:

I’m used to AI slop on LinkedIn, but not to AI slop by folks with impressive professional background. Saw a fully AI-written post from an ex-VPE at Microsoft (15 years there) and decided to say what many think when they see AI nonsense, but usually just scroll by.

Bought a new Dyson fan, set it up connected to the Wifi, and then it suddenly turned off for minutes, unable to turn back on. Turns out, it was spontaneously updating itself. This is not how a household appliance should update, I’m sorry… why do we accept such sloppiness?

Interesting to see how any and all mid-sized and above companies who take the "AI opportunity window" seriously have all built their own internal agent platform and one or more of agentic coding harness, agent sandboxing, model hosting, evals platform Building AI infra > buying right now

If you work in tech, you'll want to read the ~40-page short novel, Profession, by Isaac Asimov. If the availability of intelligence was instant, and learning things the "hard way" was considered a waste: what would the things most valued by society be? Hard to believe it's a 1957 novel.

Google Workspace's ads for paying customers could not get any more annoying I DO NOT USE AI AT ALL and I get upsells to "expand my AI access" WTH. I want ZERO Gemini for my Workspaces suite, this is some bad joke. Even if you pay you get ads, just so maddening with Google

One of the easiest ways to stand out when writing or creating videos or posting: DONT. USE. AI. Suddenly you sound distinctively different from 80%+ ppl who do and output the same verbose + nicely formatted stuff that feels all the same (+ most ppl stop paying attention midway)

A senior software engineer identifying as a “creator” working at an e-commerce company sent an AI-written email, asking to recommend their Substack. I checked out a few articles. All are… slop. Stuff that feels like it was output from ChatGPT. It’s all AI. My response:

There’s a popular theory that AI will finally make formal verification mainstream because mathematical proof of correctness will be needed when machines write most or all of the code. But will this happen? Hillel Wayne is one of the best people to answer: • YouTube: youtu.be/KSkcgIYQy0U  (cont'd)

So many interesting details. Here's one: "One thing I’ve heard from some people is “we have two humans and a bunch of agents.” I reply that this isn’t where we’re at: we still have teams with 6-8 people on average." - Katelyn Lesse, Head of Engineering, Claude Platform, Anthropic

Meta's performance review culture is becoming very problematic for its engineering culture. I said this a month ago in @pragmaticengineer.com (screenshot #1), and Semi Analysis said the same last week (screenshot #2). Engineers at Meta are world-class at optimizing for PSC...

From a friend who joined a fast-growth, later-stage startup: "I was wondering why no one is doing PRDs here. Then I realized that the Head of Product and most PMs are 25-year-olds who don't have the attention span to *read* even a 1-page doc. You lose them after 3 bullet points."

OK this made my life easier: my backend (for my admin portal) had an error popping up, and Sentry was bugging me about it. Sentry now built an AI agent (called "Seer") that can analyze the root cause, make a plan to fix, draft a fix, then open a PR. Just pushed it to prod after review!

These Google Workspace ads (for *paying* customers!) are driving me crazy I don't know why I would need a "virtual receptionist", what "Voice Standard" is, who "my callers" are, and why I would need to "guide them automatically" Is Google Workspace losing its mind? What next: proper ads?

OK this is a HILARIOUS story I heard from inside Meta: You know when Director+ folks post AI slop as "thought leader" posts? But everyone is too polite to say anything. Happened a ton inside Meta's internal "LinkedIn" (Workplace**) BUT morale is so low that lots of devs no longer gave a damn. So:

My kids keep pointing out how so many ads involving kids are AI-generated. This is one example from a government agency. It’s in so many other places as well tho with kids’ posters Kids that look more like adults, have 4 fingers…is this the “modern” advertising? All AI?
