We don’t talk enough about how morally depraved the tech industry turned out to be. Every single ounce of their self-regarding statements of values was an outright lie.
Erm, I'm sorry I tried to help answer your question about solving the Einstein field equations...
I've noticed that people who heavily use AI are way more fragile on the internet (like, when saying, "Hey, you should try working out the following calculation: ..." they interpret it as an "ad hominem").
Weirder, they overreact and start attacking you way more personally.
Just enshittification...
trolley problem diagram, with Sisyhpus pushing his boulder as the trolley car, and text that reads: Sisyphus is rolling a boluder towards the Grand Hilbert Hotel. The hotel has an infinite number of rooms, but they are all full, so they may not be able to accomodate him or his boulder. If you choose to divert him, his boulder will destroy the Ship of Theseus. But the ship has had all of its constituent parts replaced, so it may not actually be the same ship. Is Sisyphus happy?
a question for the ages, really.
I don't know why it's so hard for the Democrats to say something like this. Instead they hem and haw, and end up supporting Trump accidentally 🙄
My Mom bought some coffee from some website, and they sent the wrong coffee.
She tried to complain, but the website has an AI customer feedback system which literally cannot register there was a problem.
Welcome to the future.
Is that...Gollum? "Come see my PRECIOUS...bathroom fixtures."

I'm hardly the first person to note this, but it's enormously instructive that our President and his followers saw the message "THE ONLY THING MORE POWERFUL THAN HATE IS LOVE" and understood it, correctly, as an attack on them
Some people are asking what I want Schumer to do. He should be screaming over medical care and access to facilities. He should be going to detention facilities himself and putting his body on the line, as he did at the border in 2019. He should lean into stories about New Yorkers in detention. [1/4]
I just wish there were an "Algebraic Geometry for Differential Geometers" book out there :(
Edward Gibbon was far better with this type of juxtaposition, specifically to maximize irony. But I guess we can't all be a Gibbon...
I wish people would use commas.
For example: "While tropical countries will bear the brunt[,] cooler regions will also need to adapt."
You need that comma inserted for the sentence to make grammatical sense.
USE COMMAS, GOSH DARNIT.
But I don't think I will adequately get a chance to do this for about a month, because my sister and her husband are visiting until the end of February.
I was thinking about writing a post about the desired qualities ("desiderata") and design choices necessary when implementing a literate programming tool...especially since implementing a proof assistant *as* a literate program requires special concerns.
Perhaps I should write a meta-"literate program" to document the successes and failures of these explorations?
But to have found me on Bluesky, which is no small task, so I guess someone must be interested in what I have to say about it.
Ah, well, currently I am working my way through bootstrapping a literate programming toolkit. I feel the Markdown prototype was...inadequate for my needs.
Now that I am thinking about it, I suppose I am experimenting with several prototypes...
If you are serious about literate programming, I would still recommend building a Pandoc filter: you will save yourself a boat load of trouble.
Trouble is my business, so I'm still bootstrapping a literate toolkit in Standard ML to study implementing proof assistants.
What piqued your interest?
I'm still working on it (I realized too late that Markdown was inadequate for my purposes because I wanted to state theorems, and that forced *me* to *manually* write the theorem numbers and italicize the theorem statement).
I have a version of the Markdown locally, somewhere...
Every "Let's build an LSP server" starts off simple, then ends up with extraordinarily convoluted data structures by step 3 🫣
You know...from that land...from the land of the ice and snow from the midnight sun where the hot springs flow...
Concurrent POSIX file system operations has been verified in TaDa
www.doc.ic.ac.uk/~pg/publicat...
The POSIX shell semantics has been formalized in Lem (which extracts to Coq/Rocq and Isabelle/HOL and other proof assistants).
arxiv.org/abs/1907.05308
UNIX Path resolution has been formalized in Why3
inria.hal.science/hal-01406848...
How much of POSIX has been formalized in a proof assistant? I know of a bunch of scattered results, but they seem to be independent disjoint efforts...
And since POSIX is a multi-volume specification, I wouldn't be surprised I don't cover everything here in one thread.
After writing a POSIX-compliant shell script, then rewriting as a literate program using Noweb, I realize I might need to use an honest programming language like Standard ML to actually implement the desired program 😅
Since it's under the 35^4 ~ 1.5e6 threshold, that's the critical thing. I'd only need to pause and re-evaluate things if there were, say, 1.5e5 such identifiers.
Things reduce a little (you get 10,385 at the top-level directory, and 44,969 in subdirectories).
I'm just trying to get a feel for things (specifically if something like Stacks tags could be used for literate programming proof assistants), so over-estimating is better than under-estimating.
