Today
- I was reminded today of AI Adoption Rate Trending Down for Large Companies, a chart produced by Apollo Global Management in September 2025, which appeared to show a slowdown in …
- Instead of triggering tools one at a time across turns, agents are collapsing their tool catalog into a single exec(code) tool—chaining, filtering, and awaiting actions inside an isolated sandbox....
- Powerful AI is unpredictable. Your robotic butler may suddenly decide to kill you for no comprehensible reason, in the same way that Bing’s helpful chat AI…
- Blog About Moonbound This is a post from Robin Sloan’s lab blog & notebook. You can visit the blog’s homepage, or learn more about me. November 1, 2026 It’s been a long time since I purchased anything from a Crowd Supply campaign, but I open their email newsletters eagerly and...
- Epilogue You’re still here? Wow. Cool. After all this, I’m hoping that users notice nothing other than quicker app start times. I’m looking forward to keeping an eye on traffic and retention in the coming weeks. Wish me luck!...

- To get a good reputation in tech companies, you need to work on important projects. However, you need a good reputation first in order to get assigned important…
This week
- I spent every spare moment of the past month working on my side project. I can’t wait to share more about it with you. Every time I think I’m close to a release, I find more work to do. It feels exhausting at this point, but I’m still not losing passion for the thing I’m...
- In the previous post we looked at a simple multithreaded task executor that behaves roughly like its Python standard library counterpart. The biggest missing feature was being able to return values from run tasks via future objects. In a fully dynamic language like Python this...
- A month’s worth of security breaches in a single day – will things get worse before they improve?...
- Elegance and intelligence can have a surprisingly negative correlation. Intelligent people sometimes produce inelegant solutions because they’re capable of…
- Surprises break trust faster than setbacks. If something would surprise someone when they find out later, tell them now. Don't wait until it's convenient or until you have a fix....
- It’s time to celebrate a little win. The other day, my mom contacted me saying her 10-year-old iPhone wouldn’t turn on. After getting a hold of the device and doing some family IT support, I concluded the battery was dead. So I bought her a new (old) one on Walmart (SE 3rd gen.,...
- TL;DR Good developers’ caution about agentic development comes from knowing that built isn’t the same as working in production. I’ve been surprised by how many excellent developers have been hesitant to go all in on coding agents. These are people who usually try new ways of...
- Sometimes when I read a post, I get the growing feeling that I'm reading the output of an LLM. I can't necessarily define why, although there are the common tells (it's not the em-dashes, it's the load-bearing tapestries). As I do this my desire to read on atrophies, sometimes...
- A PostgreSQL column can be restricted to a predefined set of values using an enumerated type (enum)....
- One of the most important skills in working with AI is agency: being willing to try new and ambitious things. This is true for what you build, but it’s also…
- I’ve written before about how November 2025 was an inflection point for coding agents—the point where Opus 4.5 and GPT-5.1 crossed a tipping point that meant their respective coding agents …
- Andrej Karpathy sees a widening gap in how people see LLM capabilities. The general public has mostly not interacted with these systems. When they have, it looks like a derpy chatbot. The majority of professionals still see only a modest uplift. And a small sliver of...
- Many people think that getting “good at AI” is trivial. Sure, with some early models there were tricks you had to learn, but current models don’t need them…
- People get surprised when I mention that I currently maintain not one, not two, but 18 open source projects. For most of my career I handled this work on the side of a day job, but with my day job now gone I am dedicating more time to open source. This is my attempt to advertise...
- 27 Oct, 2026 A couple of weeks ago I quietly removed the upvote count from the discovery feed on Bear. The upvote button is still there on every post, and upvotes still decide what ends up on Trending. You just can’t see the numbers next to each post anymore. I made the change...
- Tor relay and exit IPs are public. You can find them and then use them to watch for Tor traffic in your own infrastructure....
- If a design system’s components are slow to interact with, so are any apps built with it. I timed large dropdowns and checkbox lists in some popular design systems, worked out how to make the slow ones faster, and wrote tests that fail when they’re too slow....
- AI tools are only as good as the docs you feed them. Bold text isn't a heading to a model. Here's the fix, plus two free converters....
