Hot economics take
Econ 101: In this simplified model, we assume that everyone has all the information, so we can ignore advertising and arbitrage. In more advanced courses, we will consider...
Libertarians: Nope, we're good! Let's build the economy on those assumptions.
Actual economy: *consists almost entirely of advertising and arbitrage*
Here on Earth we get sorta used to our nice round Moon. But moons don't necessarily need to be round. If they're small enough to avoid hydrostatic equilibrium (the gravitational method causing bodies to become spherical), they can take all sorta of shapes. For example, we have here a ravioli, a pancake, a potato, and an egg. Food for thought, amiright??

View down from a very high place in Petra.
Looking down on Al Khazneh, the Treasury, Petra from a tiny ledge. One of Petra's famous High Places. Possibly the scariest places I have ever been. It took me several attempts over a few years, and the help of lots of friends, to get to all of them.
I always follow back, & really appreciate & follow boosters

long post on accessibility advice from a blind screen reader user
OK #Mastodon. I've seen several toots on #accessibility for #screenreader users, however, I've not seen one from a screenreader user (as far as I know). I've used ZoomText, Outspoken, JAWS (AKA JFW), Supernova, NVDA (Windows), and VoiceOver (both on Macs and iPhone). I don't have experience with Windows Narrator or TalkBack. I would like to rectify and clarify a few small things.
First off, any awareness of accessibility issues, and endeavours to make things more accessible is great. Keep going!
But…
Blind/low-vision people have been using the internet as long as everyone else. We had to become used to the way people share things, and find workarounds or tell developers what we needed; this latter one has been the main drive to get us here and now. Over the past decade, screen readers have improved dramatically, including more tools, languages, and customisability. However, the basics were already firmly in place around 2000. Sadly, screen readers cost a lot of money at that time. Now, many are free; truly the biggest triumph for accessibility IMHO.
So, what you can do to help screen readers help their users is three simple things.
1. Write well: use punctuation, and avoid things like random capitalisation or * halfway through words.
2. Image description: screen readers with image recognition built-in will only provide a very short description, like: a plant, a painting, a person wearing a hat, etc. It can also deal with text included in the image, as long as the text isn't too creatively presented. So, by all means, go absolutely nuts with detail.
3. Hashtags: this is the most commonly boosted topic I've seen here, so #ThisIsWhatAnAccessibleHashtagLooksLike. The capitalisation ensures it's read correctly, and for some long hashtags without caps, I've known screen readers to give up and just start spelling the whole damn thing out, which is slow and painful.
That's really all. Thanks for reading! 😘
Refraction. When light is bent from an otherwise straight line while passing through a medium. You've seen this in everyday objects like a glass of water or a prism. The sunset hangs in the sky a little longer because of this.
Saturn's atmosphere, true to the physics, has been observed to cause the appearance of it bending the rings as they pass behind it. You are seeing Saturn's upper atmosphere in action!

I didn't follow the FTX disaster, Today in Tabs has a good and humorous summary

@tlsmith63 @mcneely I was actually suspecting this. Mastodon is the most GenX thing I've seen since the 90s.
