why the sharp divide around december 2022, with almost none imported before that and plenty after?

Is it ironic, though? "Right to repair" has to do with freedom, sure, but not free-as-in-beer. It doesn't mean "it costs me no money to repair things". It means "I am not prevented from repairing things".

Have you tried writing with your non-dominant hand? I'm a righty and I find left-handed writing effectively impossible.

With Talon on Mac I believe this is possible (Mac has surprisingly nice accessibility APIs), but I don't know whether Talon on X11 can do it. If it's possible it would probably(?) involve rolling your own at-spi stuff.

Is this duplication the reason why the OP is flagged? Otherwise I'm flummoxed - it seems a perfectly reasonable/normal article.

I think that's actually IBM Selectric Script, not Scribe (the images are labelled at the bottom not the top). https://fontsinuse.com/typefaces/10922/script-ibm finds two uses of it.

It turns out to be not that hard to just compute the language of the regex, if it is finite, and otherwise note that it is infinite: import Prelude hiding (null) import Data.Set (Set, toList, fromList, empty, singleton, isSubsetOf

You're correct, and I don't see any good way to avoid this that doesn't involve enumerating the actual language (at least when the language is finite). Oof, my hubris.

Here's a simple Haskell program to do it: (EDIT: this code is completely wrongheaded and does not work; it assumes that when sequencing regexes, you can take the product of their sizes to find the overall size. This is just not true. S

This depends heavily on how repetition is implemented. With a backtracking-search implementation of regexes, bounded iteration is pretty easy. But the linked webpage appears to compile regexes to finite state machines (it shows you their fi

^ and $ are a problem, although one with a workaround. The standard theory of regular expressions focuses entirely on regex matching, rather than searching. For matching, ^ and $ don't really mean anything. In particular, regexp theo

Corporations make profits if their products are worth it to people, true. But in a sufficiently unequal world, what's "worth it" to a rich person matters more in the market than what's "worth it" to a poor pers

This is a great set of examples for showing off how current chatbot AIs have impressive capabilities but are also prone to getting important details wrong. For instance: 1. The description it gives of how to generate a Shepard tone is wrong

One argument is: if font designers had to pick just one price, instead of charging a higher price to bigger customers and a lower price to smaller ones, they'd need to pick a higher price in order to recoup their costs. This would pric

Talon actually can work with Dragon; it started out requiring Dragon but has since grown its own voice recognition. Anecdotally, a lot of folks on the talon slack seem to be refugees from Dragon-based solutions, and a common observation is
