Plant ID, anyone? I picked up a handful of these from a free box in someone’s yard on my morning walk. The label just said “free succulents”.

Amusing myself by injecting false reflectances into pansharpening inputs. (CC BY-NC data from Maxar.)

I’m going to throw my coffee on the next mathematician I meet.

One of my favorite things on the Internet is when you watch a “Columbo” clip and there’s a comment where someone describes the concept of Columbo at a second-grade level and is massively upvoted for it. This sounds wry and ironical but I do honestly enjoy it.

Someone should check in on the astrophysicists.

I note that a major commercial map (left, compared to OSM on the right) isn’t showing the massive new reservoir behind the Grand Ethiopian Renaissance Dam™. It started filling in 2020.

The Pleiades, Antarctica, in synthetic aperture radar (from the Umbra open data collection).

Let’s set aside petty politics and remember the great statesman in his own words, committing one of his several unimaginably gruesome crimes against humanity.

Time keeps sneaking up on me. It’s already November again and time to pick up a new screen light for the insect sky.

The Seattle area at night, in color, from a stack of Landsat 9 scenes. Denoised with some clumsy FFT editing. I can’t imagine why you would use this for anything over one of many other options, but it’s neat that it works.

Woke up to a @aworkinglibrary newsletter.

Lest anyone think I’m making up the Greek letters.

And to be fair, sometimes you also see λ. That’s great because λ is equivalent to l, so it stands for the one of longitude and latitude that starts with l.

I don’t like what the Blue Angels think they are but I do kind of enjoy their chaotic vibes, and I feel roughly the same about my bargain-basement 500 mm mirror lens that focuses about as well as a weed grinder, so here’s a picture of the one with the other.

Very slowly converging toward the GNSS observatory dashboard I’ve imagined for years.

YouTube’s front page in an incognito window. I did look up SimCity videos from this IP recently, so that one’s on me. I think this is bad.

Gently closing the Desmos tab where I’ve been trying to build some kind of trigonometric intuitions about … ah … circles, maybe?

Lots of tinkering left to do on both the hardware and software sides, but I think my indoor GNSS setup is already picking up tidal signals on its test run.
