Making my blog feel like other people are here

I wired my homepage up with playhtml so dragging a sticker, waving the hand, or starting a song all happen for everyone who's on the page at the same time. Notes on what I built and why I keep chasing this "we're all here together" feeling.

300 Minutes a Month: Cutting My Eleventy Netlify Build Time in Half

A sequel to my Eleventy build post: this time the bottleneck wasn't the build tool, it was the hosting bill. Notes on caching webmentions and guestbook fetches, killing a dead Discord webhook, nearly breaking my JSON feed, and a git error I still don't have an answer for.

Social comments on my blog

I had a comments section on this blog since the beginning. I always felt like a comments section was kind of a requirement for a blog: it’s not just a website where you publish posts, it’s a website where you publish posts and other people can comment on them. I strongly disagreed with bloggers who openly declared that they’re removing comments from their blog because their blog is not a place for others to add their remarks, and that they can always write to the author on Twitter if they want to contact them. But one obvious problem with comments on a blog, which got worse and worse over time, was spam. People tried to solve it e.g. with captchas, though as the bots got smarter, captchas had to get more complicated and annoying. For a very long time, I had a super simple captcha in the comment form that just asked: “Are you a human? (yes/no)”. You just had to write “yes” in the text field. And for a very long time it was enough – obviously it’s trivial to make a bot add an additional query parameter, the point was that nobody would think about it when writing generic spambots, and my blog isn’t famous so the bot authors wouldn’t have come across it. Things got worse around 2018-19. I started getting comments (I had email notifications for them) that were spam that obviously got around the captcha. So I started tweaking the captcha, adding multiple slightly more complex questions, but still such that you could answer them if you’re a developer or an Apple user – “What’s the name of the Mac operating system”, “Who is currently the CEO of Apple”, and so on. But it only worked for some time, and then I started getting spam again, while making the questions progressively harder over time: At some point I figured that this had to be actual people, rather than bots, adding the comments (talking in general, not about Jerry here above), people sitting at a computer, browsing websites and filling the forms by hand, because there was no way a bot would figure out that the question was a captcha and that it had to google for a name of a function (note, this was in pre-AI times). The comments were usually either in Russian or Ukrainian, or linking to some local service companies in some random small town in the US. There was no way I could out-captcha an actual human that can google for an answer. But it wasn’t a huge problem, I didn’t get many of those comments, and it was fairly easy to filter them out still by content, so I didn’t bother changing the system further. But here’s the thing: it’s not 2010 or 2018 anymore, and some other things have changed in the meantime too. I think it’s a bit of a truism that blogs and “blogosphere” aren’t what they used to be 15+ years ago. People post their thoughts on social media, Instagrams, Facebooks, LinkedIns, Substacks, record Tiktoks, YouTube videos or podcasts. Reading and writing blogs and commenting on them is a very niche hobby, let’s face it. After 2020-21, when for a while I was getting a ton of comme…

The Fetch API gave JavaScript runtimes a shared vocabulary for HTTP. But HTTP has capabilities that Fetch can't express, and every runtime has diverged trying to work around the gaps.

Alli AI Launches WordPress Plugin to Make Sites Visible to ChatGPT, Perplexity, and Claude

Rehoboth Beach, DE, June 30, 2026 — Let’s be completely blunt: if your website relies heavily on JavaScript, there’s a good chance it’s a ghost to the AI-powered search engines that are increasingly dominating how people find information.

I made all my posts standard.site compatible last weekend, which means I can write in pckt.blog, Leaflet, or Offprint and have the post show up on keith.is. This is my first one from pckt 🎉 🎉 🎉!! I'd been using a combination of Tina, and just writing in my editor. Then I went to share one of those posts on bluesky to see the cool new embed and saw that.... and my old OG image. I think I spent fifteen minutes on it once when I migrated from eleventy to Astro, gave it some bright colors and a shap...
