Classical ("discrete") error correction is like: assume every bit you send has an independent probability p of being flipped. Figure out ways of encoding/decoding a message of n bits using n+k bits that minimizes the probability of an error. Where can I read about the ℝ-analog?
"Critical theory" is about points where the derivative of some function under consideration is zero, right?
@davidmanheim There's "CLIP interrogator", closest thing I know of to this.
It's the first time I've been skiing since I grew a beard - definitely an interesting experience 😂

Mastodon meta
My least favourite sharp edge of Mastodon is the fact that when you view someone else's post you only see replies to it that are known to your server - so there's actually a good chance there will be replies that are completely invisible to you, especially if you run your own instance
I'd love it if tapping a post kicked off a request back to the original server that fetched the current reply count and provided a "view all replies" button if there were replies not yet visible to me

The bit about a lawyer being stopped from entering a music hall in the US because its facial recognition system picked up that she's part of a law company that's suing them is even crazier than I thought.
The law company isn't suing the music hall - it's suing a restaurant, in another state, which is owned by the hall's parent company MSG Entertainment. MSG gone ahead and harvested photos of all the lawyers in the firm and fed it to an image recognition system to ban them from every MSG Entertainment owned location.
People always tell me that if you've got nothing to hide then you've got nothing to fear. She's got nothing to hide and they still went after her.
If this doesn't start making people worried about facial recognition then there's serious trouble coming.

You have a problem. You use regular expressions. You now have solved your problem with a tool used by thousands and thousands of engineers for decades.
@julesh Currently I have twitter-->mastodon crossposting set up and I check both. But Mastodon feels very quiet right now.

Perhaps Mathstodon can be a place to note some folklore #MathTricks that are useful but too trifling to devote an entire paper to. Here's one (that I recalled on browsing MathOverflow https://mathoverflow.net/questions/435728): If one is trying to prove a Hilbert space identity or inequality which is invariant under a unitary group action, one can often reduce "for free" to the irreducible components of that group action.
