While providing tech support for my FIL:

FIL: What's that screen?

ME: The terminal. You should never use it.

FIL: Never?

ME: So you know how I'm allowed to watch you open the electrical panel and swap out breakers, but I'm not allowed to ever open up it myself?

FIL: Ah! I understand, thank you.

Before (2012) / After (2025) Rue le Vau, Paris 20. The change here is so radical that perceiving the photos as aligned is difficult (see the orange building and the trees on the left). In 2024, this section was converted into a school street with a bike lane running through the greenery.

Area is definitely better than radius, but not perfect. Area perception isn't itself linear. See en.wikipedia.org/wiki/Stevens.... Basically, people perceive larger circles as less large than they are.

In general, I tend to avoid size for accurate perception of magnitudes for this reason.

Why don't AI people ask an AI model to help with naming? (Or maybe that's what they all did...)

While I do research that is intended to live on, I don't think it would be sustainable for everyone to do the same.

It's good and necessary that people do different research with different goals. Reproducibility is a shared goal, though, that probably all research types should strive for.

There is a lot of great work on how viewers interpret uncertainty and how to visualize uncertainty at the last few years of the @ieeevis.bsky.social conference.

Great post. I agree that research should be abstracting away from the implementation.

I will add that protocol design itself can be a research activity and that software artifacts can be enablers of follow up research. I talked about this at the Stanford HCI seminar youtu.be/6DIIkX19ihs.

Zürich has passed parking reform similar to what Halifax Council has been debating this year.

Residents of Zürich will pay parking fees based on the weight of their car. A goals of this reform is to reduce the number of large SUVs in the city and thus use public space more fairly and sustainably.🧵

That’s super interesting. Writing thoughts to to files could make it behave very differently from other systems making it harder to switch between models. I was kinda hoping for commoditization but I guess we get specialization.

LLM safety work often reasons over high-level policies (be helpful & polite), but must tackle on-the-ground cases (unsolicited money advice when stocks are mentioned). This can feel like driving on an unfamiliar road guided by a generic driver’s manual instead of a map. We introduce: Policy Maps 🗺️

Feels surreal to have professional milestones amidst current events, but I'm sharing for folks who still want to learn about accessibility in visualization.

Back in June I spoke at @datavizsociety.bsky.social's Outlier about "softerware" (below) and now our paper has been officially accepted! 🎉🎉

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge?

It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.
