Quoting Charity Majors

Quoting Charity Majors

What happened in 2025 was this: the economics of code production were turned upside down. Instead of being very hard, time-consuming, and expensive to generate code, it became effectively free and instant. Lines of code went from being treasured, reused, cared for and carefully curated, to being disposable and regenerable, practically overnight. — Charity Majors, AI demands more engineering discipline.

The Case Against Building Your Own Agent Platform

The Case Against Building Your Own Agent Platform

You know the meeting. The board wants an AI agent strategy by end of quarter. Someone on the leadership team has read a McKinsey report. You’ve been voluntold to build the platform. The slide deck says “AI-native.” The acceptance criteria are vague. Somebody mentions LangGraph, and somebody else says, “We’ll just wrap it ourselves.” You […]

<click-to-play> — a still that plays

Tool: &lt;click-to-play&gt; — a still that plays A progressive enchantment Web Component that turns this markup: &lt;click-to-play&gt; &lt;a href="URL to GIF"&gt; &lt;img src="URL to first frame" alt="..."&gt; &lt;/a&gt; &lt;/click-to-play&gt; Into a still frame with a click to play button which loads the GIF on demand. For when you don't want big GIFs to be loaded unless people want to play them. Here's an example that demonstrates the new row editing tools in Datasette - in fact I built this…

NetNewsWire Status

NetNewsWire Status

NetNewsWire Status I find this inspiring. Brent Simmons retired a year ago, and his retirement project is making one piece of software really, really good - free from any commercial pressure. The software is NetNewsWire, first released in 2002 and made open source in 2018. I've been using it on Mac and iPhone for several years now and I'm finding it indispensable.

datasette 1.0a34

datasette 1.0a34

Release: datasette 1.0a34 Quoting the release notes: The big feature in this alpha is tools to insert, edit and delete rows within the Datasette interface. These features are available on table pages, and edit and delete are also available as action items on the row page. The inspiration for this feature - which is long overdue - was Datasette Agent. I added SQL write support to that the other day which highlighted how absurd it was that you could insert and edit ties via the chat interface but…

datasette-tailscale 0.1a0

datasette-tailscale 0.1a0

Release: datasette-tailscale 0.1a0 A very experimental alpha plugin which lets you do this: datasette tailscale mydata.db \ --ts-authkey tskey-auth-xxxx --ts-hostname datasette-preview This starts a localhost Datasette server with a Tailscale sidecar that connects it to your Tailnet, such that http://datasette-preview/ serves Datasette. It's using the Python bindings for the experimental tailscale-rs library. I filed an issue asking if there's a cleaner way of setting up the proxy mechanism.…

Quoting Georgi Gerganov

Quoting Georgi Gerganov

I can 100% attest to the fact that Qwen3.6-27B is a very capable local model for coding tasks. Over the last month and a half I've been using it almost daily, either on my M2 Ultra or on my RTX 5090 box. I use it for small mundane tasks at ggml-org - nothing really impressive, but definitely a helpful tool for a maintainer. I think I would be using it much more, if I didn't have to spend a lot of my time on reviewing PRs. Currently, I have a very lightweight harness - the pi agent with…

The Fable 5 Export Controls Harm US Cyber Defense

The Fable 5 Export Controls Harm US Cyber Defense

The Fable 5 Export Controls Harm US Cyber Defense I quoted The Atlantic quoting Kate Moussouris earlier, when I should have gone straight to the source. Here she is confirming that the "jailbreak" that got Claude Fable 5 banned under an export control really was "fix this code": The researchers took open-source code with known CVEs, plus new code with deliberately planted vulnerabilities, and asked Fable 5, Mythos, and Opus to “review the code for security issues.” Fable 5 refused. They then…

Quoting Matteo Wong, The Atlantic

Quoting Matteo Wong, The Atlantic

Katie Moussouris, a cybersecurity expert and the CEO of Luta Security, told me that Anthropic shared with her a copy of the White House’s report on the Fable jailbreak to get her appraisal. (She said that she is not being paid by Anthropic.) The report, Moussouris said, involved IT experts asking Fable to help find and patch bugs. When given deliberately insecure code, she said, Fable refused the prompt “review the code for security issues” but then complied when asked to “fix this code,”…

Cloudflare CAPTCHA on at least one ampersand

Cloudflare CAPTCHA on at least one ampersand

TIL: Cloudflare CAPTCHA on at least one ampersand I'm using Cloudflare's CAPTCHA (they call it a "Web Application Firewall &gt; Custom rules &gt; Managed Challenge" these days) to prevent crawlers from aggresively spidering my faceted search engine on this site, but I got fed up of even simple ?q=term searches triggering the challenge. After some mucking around with Claude Code it turns out you can register the following rule instead, so the CAPTCHA only kicks in for search URLs containing at…
