- New from Anthropic today is Claude Cowork, a “research preview” that they describe as “Claude Code for the rest of your work”. It’s currently available only to Max subscribers ($100 …
- Agent Safety is a Box Keep a lid on it. Before we start, let’s cover some terms so we’re thinking about the same thing. This is a post about AI agents, which I’ll define (riffing off Simon Willison1) as: An AI agent runs models and tools in a loop to achieve a goal. Here, goals...
- It is not enough to assess whether an idea is good or not but rather necessary to compare it to all other ideas you could be pursuing...
- I’ve been slowly reading my copy of “The Internet Phone Book” and I recently read an essay in it by Elan Ullendorff called “The New Turing Test”. Elan argues that what matters in a work isn’t the tools used to make it, but the “expressiveness” of the work itself (was it made...
- As I was playing around with contrast-color(), I got a wild idea that you could use contrast-color() to invert its return value by nesting it: contrast-color(contrast-color(var(--some-color)). When would this be useful? Uh… Good question. I couldn’t come up with an example right...
- Last month I wrote about porting JustHTML from Python to JavaScript using Codex CLI and GPT-5.2 in a few hours while also buying a Christmas tree and watching Knives Out …

- I love writing software, line by line. It could be said that my career was a continuous effort to create software well written, minimal, where the human touch was the fundamental feature. I also hope for a society where the last are not forgotten. Moreover, I don't want AI to...
- There has been so much written about the "unsustainable" AI capex recently. Thinking through this recently it occurred to me this is potentially the wrong way to think about it, and it's actually more likely from my research we're going to experience a very significant crunch on...
- A few months ago, users started reporting that Ghostty was consuming absurd amounts of memory, with one user reporting 37 GB after 10 days of uptime. Today, I'm happy to say the fix has been found and merged. This post is an overview of what caused the leak, a look at some...
- In my first post on contrast-color() I demo’d using color-mix() to change a background-color on hover, but I will be honest… mixing black and white isn’t always what you want. It would be cool and helpful to coerce contrast-color() to return either 1 or -1 so that we could...
- If you ask people why they are using AI (or want other people to use it) you get a ton of different answers. Typically none of them contain the real reason, which is that using AI is dirt cheap. Between paying a fair amount to get something done and paying very little to give...
- One predictable pain point with contrast-color() is that it only returns black and white named colors. From a design systems perspective, that’s not ideal because you want your colors. You want your harmonious brand and the colors you and your team spent thousands of man hours...
- Mcp-cli is a lightweight CLI that allows dynamic discovery of MCP, reducing token consumption while making tool interactions more efficient for AI coding agents....
- Instead of pursuing what you love you should pursue what you are good at as the success will compound which is what will really keep you engaged. This goes for hobbies as well as work and keeping them in balance is key....
- All You Need is Specs? Today I’m releasing whenwords, a relative time formatting library that contains no code. whenwords provides five functions that convert between timestamps and human-readable strings, like turning a UNIX timestamp into “3 hours ago”. There are many...
- Long term readers may wonder – VS Code, Ben? Really? Let’s not getting into that now, instead, just the issue before us. The problem before us is that we want to highlight just the active indent guide of the code in the editor. By default, VS Code highlights both the active...
- Firefox 146 added support for contrast-color() joining Safari 26 in the First Implementor’s Club. For those unfamiliar, contrast-color(<color>) is a new CSS function that will take a <color> as input and returns either white or black depending on which has the most contrast. The...
- My favorite albums from last year. Balkan brass, an acoustic favorite of 80s returns, Ethio-jazz, Guatemalan singer-guitarist, jazz-rock/Indian classical fusion, and a unique male vocalist. more…...
- Anthropic report on how their AI is changing their own software development practice. Most usage is for debugging and helping understand existing code Notable increase in using it for implementing new features Developers using it for 59% of their work and getting 50%...
- Every millisecond your JavaScript runs is a millisecond borrowed from your users. Here's how to be a better guest on the main thread....
