I was experimenting with wasmtime-py today and found the current documentation didn't quite give me the information that I needed. …
If you ever run into instructions that tell you to do this: …
I finally figured out a process that works for me for hacking on Python CLI utilities using uv to manage my development environment, thanks to a little bit of help from Charlie Marsh. …
I ran https://simonwillison.net/ through PageSpeed Insights and it warned me that my static assets were not being served with browser caching headers: …
I'm still working towards adding multi-modal support to my LLM tool. In the meantime, here are notes on running prompts against images and PDFs and audio and video files from the command-line using the Google Gemini family of models. …
With Claude's help I figured out what I think is the most basic version of a static site generated using Hugo. …
I live in El Granada, California. Wikipedia calls us a census designated place - we don't have a mayor or city council. But we do have a Community Services District - originally responsible for our sewers, and since 2014 also responsible for our parks. And we get to vote for the board members in the upcoming November election! …
I managed to get my Homebrew installation back into shape today. The first problem I was having is that it complained that macOS Sequoia was unsupported: …
I ran a survey on Twitter the other day to try and figure out what people mean when they use the term "agents" with respect to AI. …
Today I heard about the sqlite3-rsync command, currently available in a branch in the SQLite code repository. It provides a mechanism for efficiently creating or updating a copy of a SQLite database that is running in WAL mode, either locally or via SSH to another server. …
OpenAI's DevDay event yesterday (October 1st 2024) didn’t invite press (as far as I can tell), didn’t livestream the event and didn’t allow audience livestreaming either. I made a last minute decision to live blog the event myself. …
I decided to have a poke around and see if I could figure out how the HTTP streaming APIs from the various hosted LLM providers actually worked. Here are my notes so far. …
I figured out this pattern today for testing an HTML table dynamically added to a page by JavaScript, using Playwright Python: …
I'm writing some quite complex pytest parameterized tests this morning, and I was finding it a little bit hard to read the test cases as the number of parameters grew. …
Alex Garcia's sqlite-vec SQLite extension provides a bunch of useful functions for working with vectors inside SQLite. …
I published a reusable Django application today: django-http-debug, which lets you define mock HTTP endpoints using the Django admin - like /webhook-debug/ for example, configure what they should return and view detailed logs of every request they receive. …
I like to write the release notes for my projects by hand, but sometimes it can be useful to have some help along the way. …
I fell down a bit of a rabbit hole this morning. In trying to figure out where the idea of celebrating World Wide Web Day on August 1st came from I ran across Tim Berner-Lee's original code for the WorldWideWeb application for NeXT on the W3C's website: …
Via Mariatta I found my PyVideo speaker page, and thanks to that page I learned that a talk I gave in 2009 had been rescued from the now-deceased Blip.tv and is now hosted by the Internet Archive: …

I really like auto-formatting tools like Black. I've been hoping to find one that works with Django and Jinja templates for years. …

I found a better way to listen to a whole web page through text-to-speech on Mobile Safari today. …
I scraped a pass on my Ham radio general exam today, on the second attempt (you can retake on the same day for an extra $15, thankfully). …
