@nasser Ah, but how do I get credit for being cool if I don’t use the cool name? Checkmate.
I would just like to assure everyone with a strong opinion about a huge, complex, social topic that you’re really close to winning everyone over if you can just post three or four more specific incidents that really demonstrate your argument. Those compelling examples of single things will finally prove the general case. Just point out a few more instances of someone wearing sandals winning a charity raffle or a bingo game and we’ll all believe sandals are lucky. Keep going! Almost there!

Longer post(s) to come after the morning school rush, but!
The Fediverse governance research @darius and I have been working on this year—with the absolutely central participation of so many wonderful Mastodon and Hometown server teams—is out:

A bad thing about social media is this pattern where a person with expertise starts rebutting bad ideas, and it’s great, but over time it primes them to see everyone who doesn’t hold exactly their opinions as part of a horde of goons with terrible ideas, because that’s who they end up interacting with.
Eventually their online persona is, like, Truth Gladiator. And that’s so much less interesting and important to me than Thoughtful Person With Useful Perspectives.
@llimllib Scared the absolute bejezus out of me when I saw it as a preteen, I’ll tell you that much.

As a Blind person i never thought i would be on social media savoring photos. But the communal Mastodon alt text game is so strong that sweet, poetic or silly descriptions abound on my timeline. Thanks to legions of people who take time to write a meaningful description of the ephemera they post, i learn so much about insects, plants, buildings, memes — all dispatches from a dimension of the world that i otherwise wouldn't experience. If you're wondering whether anybody reads these things: YES.
@grimalkina Comparably, perhaps, I enjoy this meme but I’m not sure how true it is in general, beyond a particular sub-sub-sub-culture where I’m comfortable.
@djh For sure. I share this annoyance. Also:
– Not even trying to understand miltispectral bands.
– Sample-normalizing calibrated, linear data, thereby losing information.
– Augmenting in ways that might make sense for snapshots but do not reflect anything that you would actually see in geospatial data.
– Assuming there is little information in fine details because they’re used to Bayer demosaicked images, where that’s interpolated anyway.
@martinfleis Just wanted to say I really appreciate the paragraphs on “aspatial imagery” – I’ve been working on something that depends on this idea and have been dreading trying to explain it. You’ve done far better than I could have.
@djh (I am kind of mildly anti-vit, or anti vits being applied everywhere for no particular reason (see ConvNeXt, which I found pretty convincing), but I think the spatiotemporal stuff starts to get into the level of complexity where they might be justified.)
@djh I think one barrier here is bootstrapping vit training, which as I understand it can be quite tricky at scale – they don’t have the same convexity advantages as CNNs. I’m basing this mostly on https://www.sciencedirect.com/science/article/pii/S003442572300439X (presented well in https://www.youtube.com/watch?v=vacNCxMA_Gw).
@urschrei Mulder tosses a thick folder on Scully’s desk and flops into his chair – face neutral, perhaps faintly amused. “Heard of the eminent old man who acts like a public service is his personal hobby project?”
@rnanclares Thank you for letting me know.
@rnanclares Something about the way I have used the word “surface” seems to be causing a miscommunication. Think of it this way: I’m interested in the reflectance of the sun as seen from the outside.
@rnanclares I’m not asking about light emitted by the sun specifically, and consider that (say) Jupiter doesn’t have a sharp surface either, but does have a reasonably well defined (though variable) reflectance from its outside.
What’s the surface spectral reflectance of the sun? I know it’s approximately a black body radiator, but clearly it doesn’t follow that it’s pure black. So what is it?

Today, we salute Thomé de Gamond, early Channel Tunnel proponent, who had to figure out the geology of the seabed first. https://m.gutenberg.org/files/66685/66685-h/66685-h.htm
