Today
- Z.AI ran a full model release on domestically manufactured Chinese chips. Impressive, but EUV lithography is a hard wall and the gap with Western inference hardware is more likely to widen than close....

- You can now cap token usage with TokenLimiterProcessor — a processor that enforces a limit on inputs and generated responses. Configure it as an inputProcessor ......
- You can now enforce spending limits with TokenCostControl — a processor that reads cumulative costs from observability data. Configure a hard maxCost cap that b......
- At the start of this year I began developing an application called Origami Projector for editing sites.
- In 1973, Tom Lehrer famously sang that “selling out is easy to do”. That may have been true in the seventies, but it’s not true today: selling out requires both…
- The ebook meets the Web Content Accessibility Guidelines (WCAG 2.1 Level AA) because the format wouldn't let me fake a heading and a browser audits every build, not because anyone scheduled a week for it. The parts Markdown can't check, like color contrast, axe-core catches...
- Asana migrated off testing framework Enzyme in two weeks: without AI, this work would surely have been kicked down the road. Airbnb and Uber share similar stories and AI seems excellent at migrations....
This week
- 807 blog posts across 14 years. That’s how much I’ve published on my blog at the time of this writing. And here’s the question I’ve been turning over in my mind: “How do I convey that kind of volume across time in a more interesting way than a mere reverse-chronological list?”...
- Lots of organizations are excited about what AI can do to streamline their processes, save money, and juice margins. But AI's capabilities are founded on the data that AI accesses, and for many organizations that foundation is little more than sand. Pramod Sadalage and Prem...
- This email is a response to the 50+ podcast pitches that arrived in my inbox just last month, and keep arriving in growing numbers, from PR agencies and marketing teams at various companies. It's also a message to tech founders building stuff for developers: focus on building...
- When and how CSS custom properties are calculated might not be what you expect, and it has a big impact on your styles. The default Take this HTML: <div></div><div class="second-item"> <p>…</p></div> And this CSS: .second-item { --index: sibling-index(); & > :first-child {...
- In October, a new movie will be released based on one of my favorite books, Klara and the Sun. This has happened a lot for me recently (see The Three Body Problem, The Martian, Project Hail Mary, and Tomorrow and Tomorrow and Tomorrow). I know it’s cliché to say that the book is...
- Today we're announcing the Mastra Helm chart for self-hosting Mastra on Kubernetes clusters. The Helm chart deploys the same topology we use in the Mastra platf......
- I'm currently working on migrating my open source projects from GitHub to a self-hosted Forgejo instance. As part of this effort I often end up looking through the Forgejo source code to figure out if there are hidden ways to configure certain things to my liking when I can't do...
- Dave Rupert wrote about shipping microlighter: a tool for handling syntax highlighting using the CSS Custom Highlights API. I saw his post the day he released it, and I had an implementation PR up for my blog by end of day. Then, like I do with so many things, I let it sit...
- Modern IDEs let you jump from project to project with ease. Neovim doesn’t have this feature, so folks usually keep a few terminal windows or tabs open or jump between Zellij or tmux multiplexer panes. As you can imagine, there are also a gazillion plugins to fill this gap. None...
- 25 Aug, 2026 I write about journaling a lot, since it’s honestly my most important practice. In my most recent post on the subject I made the case that active recall is an effective way to remember things, whether that be ideas, thoughts, or events. I'd like to expand on that...
- Your Mastra agents can now load tools on demand with ToolSearchProcessor for sharper tool selection and reduced token usage and cost. The processor exposes two ......
- Your Mastra agents can now load skills on demand with SkillSearchProcessor to reduce context bloat, token usage and cost. The processor exposes two built-in too......
- I was listening to Ezra Klein’s interview with Helen Toner about the recent OpenAI hack of Hugging Face and the subsequent discovery that there were swarms of agents inside OpenAI doing unsanctioned activities. One of the points Klein made was that at no point did any of these...
- On my icon gallery sites, I have metadata I’ve manually added over the years to tag certain icons as being predominantly “blue” or “orange” or some other color. Then I use this metadata to present icons of (roughly) the same color. It’s kinda neat to be able to browse a wall of...
- There’s some talk today about how agentic coders are balking at Anthropic’s pricing and adopting alternatives. I was reminded of a thought I had in the weeks following Fable’s release: the free lunch was over. When Moore’s Law was in effect, it didn’t make sense to ruthlessly...
- You can now assert a whole conversation with multi-turn evals. Gates assert deterministic actions like tool calls, and scorers can use an LLM-as-judge to grade ......
- Winter 2025 was the tipping point for coding agents. Summer 2026 is shaping up to be the same for open weights - and compute supply, not model quality, is now setting the price....
