The team that worked on this is incredible. It was a completely painless migration for me, and what they built was so much faster and easier to use. More great work by great people, very happy that we share it.
New on our Engineering blog: Creating in-house source control.
In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale.
Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

there’s a special form of ai psychosis i keep seeing over and over where people are convinced that they can tell the models to optimize some end goal without ever looking at the approach and then they end up with something that looks fast on a benchmark but actually sucks. unfortunately the new bitter lesson we will have to learn is that this doesn’t actually work and you still need to care about software engineering.
walking around the upper west side we drop into a brunch place, see AI art on the menu, AI art on the walls, not the vibe
turn the corner and go into a different cafe, much better vibe, get to the counter: AI art menu, AI art specials
I love technological progress sometimes.
This stack of CDs and DVDs from my childhood is 253 discs tall and stores almost 500GB of data.
The microSD card in front of the stack holds all that and more in 26,000x less volume and 15,000x less mass.
in sf for only 4 hours so far and I already strongly prefer the new waymos to the old waymos – at San Francisco, CA
First time back in SF after a couple years and I find out that they opened another El Farolito three blocks from the original.
Cities aren’t supposed to change like this.
people often ask me why I’m still on twitter
and the answer has many parts, but the biggest is that it’s been an extremely strong net positive on my entire career and life

I got inspired by @fulligin’s amazing 3D model of Grace Cathedral last month, so I tried creating a model of Lower Manhattan and used Claude as much as possible.
It went… pretty well, all things considered! And you can play with it in your browser on a phone, too.
Today’s project: replacing a rusted old metal grate with a precision-cut metal part from @sendcutsend, designed with Claude.
Less than a week from tripping over this to having a purpose-built fix. Claude knows how to speak DXF fluently, so I could just describe the part. – at Brooklyn, NY

I blogged about the entire project here: petersobot.com/blog/using-mo…
And huge shout out to my friends at both @modal and @Cloudflare - both incredible platforms which made this project a breeze to build. (cc @bernhardsson, @kenny_ning)

Blob storage like AWS S3 is a modern marvel. So much of what we can do with computers today is enabled (or greatly simplified) by fast, ~unlimited read/write access to ~anything.

oh that? don’t mind that. Claude’s just running over there. what’s the VCR for? why so many exposed wires? I just followed its instructions on what to plug in where. don’t worry about it.
