The first four weeks of digital solargraphs are in the bank! Over 45,000 individual shots across two cameras, 380GB of RAW files condensed into a few seconds of video 😅

I guess watching Widow's Bay gave us a false sense of security and comfort around (tame and funny) horror. Watching Obsession (2026) was something else, though… not for the faint of heart. Good movie for sure, but I know why I normally stay away from horror movies.

The daily solargraph is the continuation of my digital solargraphy project. You can watch every day's capture as a little video, or scrub through manually. The new capture is added every night around 10pm PDT. eagereyes.org/app/daily-so...

It's weirdly sad/funny that all the half-broken Washington Post news graphics I linked from this blog post in 2016 are now entirely unreachable, while the NY Times Flash-based example I described as "you're now just staring at a big hole" works again. eagereyes.org/blog/2016/th...

Spending some time to clean up old links in blog posts and comments. A lot of things have gone away, pretty sad to see. So long Charticulator, Circos, iCharts, kartograph, Kuler, a bunch of yearly EuroVis and VIS workshop sites (BELIV!), and a whole lot of people's academic websites.

Something fun you can do with digital solargraphs that you can't with paper, is look at each daily streak separately and admire the patterns. Here are four from the last few days in Seattle, the first on the solstice (6/21), and then 6/26-28.

It's kind of odd how The Twist clouds so much of my memory of The Sixth Sense. It was an incredibly well done movie, might be time to re-watch (27 years later 😬). youtu.be/ujH-6k218Kc

This isn't so much a chart as a visual calculator (a nomograph or nomogram, as it says in the title). They were very common before computers/calculators, and encoded a fair amount of knowledge about their specific application areas and use cases.

I've built a solargraph simulator using solar irradiation data. Pick a place on Earth, animate the solargraph, draw just one point per hour for analemma view, or switch to panorama mode that projects the solargraph into a virtual sky you can navigate. eagereyes.org/app/solargraph

There's something about USB power I just don't understand. This is old-school 5V power, not power delivery. It seems that USB hubs provide more power when no host device is present than when there is a computer there. So devices might work without host, but fail to boot up when there is one.

Unsurprisingly excellent piece from Ted Chiang about LLMs and particularly about Claude. Claude (or any other LLM) is not conscious or "intelligent" in the general understanding of the word, but if it were, then it would be, essentially, a slave. www.theatlantic.com/philosophy/2...

No, Artificial Intelligence Is Not Conscious
Taken to its logical conclusion, this line of thinking is absurd—and damning.

That's-a-me (when I was still at Observable)! We mostly talked about my background, industry vs. academia, visualization research and how much it makes it into products, and also treemaps. Oddly, pie charts only make a very brief appearance. It was fun to record, and I think it's worth your time.

I just vibe-coded a little Python script that is currently deleting all my old imported tweets that I had transferred over here. It's pretty simple, just goes by post date (since I didn't post here before I stopped tweeting), and the BlueSky API and Python SDK (and Copilot…) make this super simple.

I'm sorry to say that the MurderBot show on AppleTV was pretty meh. The books have more dry humor and good pacing, but the show is just boring. There's also a lot more world-building in the books. Since they're all inner monologue, a lot can be explained without it feeling overdone.

It looks like CloudFlare don't delete your pages when you delete your account. I still get traffic report emails every so often, even though I've deleted my account with them 18 months ago. There's no way for me to delete the pages now, since my account is long gone.

TIL that the Butlerian Jihad in Dune is (possibly) named after Samuel Butler, who wrote a famous letter in the 1860s, and later a book, worrying about the evolution of machines, and arguing for their destruction. arstechnica.com/ai/2025/01/1...

There's a lot going on, but this is a little dramatic. The actual change here is around 1.5% (from about 20.48:1 to around 20.75:1). Even a cropped axis can leave a little more room for a more nuanced picture, IMHO.

I mean I get it, but it's still useful to think of kWh/day, because electricity is sold in kWh (so you can figure out what it'll cost to run per day, month, etc.). It's also meaningful because it's an average over time, it doesn't draw a constant 125W. That aside, I completely agree.

Kind of related to my previous post, this documentary on Phil Collins is pretty good. Especially if you don't know that he was originally the drummer in Genesis. But they also cover a lot of other ground and talk about the toll drumming ended up taking on his health. youtu.be/WdGmydR715Q
