Startup Advice: "If you can keep your head when all about you are losing theirs its just possible you haven't grasped the situation."

pi + ghostty running entirely in a cloudflare workers durable object. sqlite based file system + js code exec + cron support. The best part is it can deploy worker sites using Dynamic Worker Loaders.

I love this. Tests are a class of “embarrassingly parallel” computer problem and scaling out makes so much sense. Next step: GitHub Actions replacement

repeat after me: lines of code is not a measure of productivity

I know Silicon Valley startups don't want to hear this..... But the combination of someone in the trades with deep domain expertise and Claude Code will run circles around your generic software. I talked to Cory LaChance this morning, a mechanical engineer in industrial piping construction in Houston. He normally works with chemical plants and refineries, but now he also works with the terminal He reached out in a DM a few days ago and I was so fired up by his story, I asked him if we could record the conversation and share it. He built a full application that industrial contractors are using every day. It reads piping isometric drawings and automatically extracts every weld count, every material spec, every commodity code. Work that took 10 minutes per drawing now takes 60 seconds. It can do 100 drawings in five minutes, saving days of time. His co-workers are all mind blown, and when he talks to them, it's like they are speaking different languages. His fabrication shop uses it daily, and he built the entire thing in 8 weeks. During those 8 weeks he also had to learn everything about Claude Code, the terminal, VS Code, everything. My favorite quote from him was when he said, "I literally did this with zero outside help other than the AI. My favorite tools are screenshots, step by step instructions and asking Claude to explain things like I'm five." Every trades worker with deep expertise and a willingness to sit down with Claude Code for a few weekends is now a potential software founder. I can't wait to meet more people like Cory.

We've been building an internal Claude Code plugin system at Intercom with 13 plugins, 100+ skills, and hooks that turn Claude into a full-stack engineering platform. Lots done, more to do. Here's a thread of some highlights.

gabby gets it dead right one implication of this is that engineering as a discipline isn’t going anywhere, and engineering meta systems to make systems is still engineering. engineering meta systems still requires rigor, form, principles, specificity, disambiguation even if the layer of abstraction is one level higher, even if that layer is magic in a way that is novel to all engineering paradigms that came before even if engineering a system full of magic spirits converges on eco-engineering converges on gardening converges on memetic engineering the engineer still requires common language, requires discipline, requires a toolshed Prose is a language, Forme is a discipline, Press is a toolshed the OpenProse stack is built on the thesis that the era of the engineer has barely begun

recommended reading sure to ruffle some feathers. but it's largely true for now. keeping the complexity off the bay is really hard, espwcially if you go full agent orchestration. even if you don't, and human in the loop a lot, automation bias kicks in and your reviews of agent generated code become mostly performative.

.@nodejs has always been about I/O. Streams, buffers, sockets, files. But there's a gap that has bugged me for years: you can't virtualize the filesystem. You can't import a module that only exists in memory. You can't bundle assets into a Single Executable without patching half the standard library. That changes now 👇

🤯 You can now launch Claude Code sessions on your laptop *from your phone* This blew my mind the first time I tried it

Ghostty 1.3.1 is now out, most importantly fixing the phantom mouse drag/select/scroll events on macOS. This release also includes improvements to AppleScript support and a couple dozen bug fixes. ghostty.org/docs/install/r…

Anthropic shipped generative UI for Claude. I reverse-engineered how it works and rebuilt it for PI. Extracted the full design system from a conversation export. Live streaming HTML into native macOS windows via morphdom DOM diffing. Article: michaellivs.com/blog/reverse-e… Repo: github.com/Michaelliv/pi-… Built on @badlogicgames's pi and @DanielGri's Glimpse.

OK, well. I ran /autoresearch on the the liquid codebase. 53% faster combined parse+render time, 61% fewer object allocations. This is probably somewhat overfit, but there are absolutely amazing ideas in this.

approaching peak slop

If your tests do not fail, that's not always a green light, that might be a red flag Ask Claude to introduce violations (subtle and obvious) in the implementation and check if the verification catches them Effectively briefly reversing the role of test and system under test

Don't let AI service providers dilute the meaning of "local". If it can't run offline on compute and data you actually own, it's not a Personal Computer.

sent this to the team today everything great comes from being able to delay gratification for as long as possible and it feels like we're collectively losing our ability to do that

Ghostty 1.3 is now out! Scrollback search, native scrollbars, click-to-move cursor, rich clipboard copy, AppleScript, split drag/drop, Unicode 17 and international text improvements, massive performance improvements, and hundreds more changes. ghostty.org/docs/install/r…

Key takeaway from all the comments: Use nested skills. e.g. instead of separate skills for "create PDF" and "parse PDF", have one skill called "manage PDF" which then routes to the relevant sub-skills With good nesting, this can likely scale to 1000+ skills/sub-skills!
