I think I've gotten to a point of my Choro guitar playing where I can tell it sounds bad, but it... feels good?
It's nice to no longer dread practicing!

As a Brazilian reading an Argentinian, it gives me no pleasure to recommend an essay that focuses the unhealed collective soccer trauma of an entire nation into the sickest, sickest of burns
But it is a great damn essay, and an all timer of a burn

New Substack post: we’ve all heard about the Great Feminization article and we’ve all delighted at how badly even friendly conversations went for its author. Now we ask the question: is Helen Andrews just wrong, or is she interestingly wrong?

I love our roborock, but it loves to play footsie when I'm working on my standing desk and it kind of freaks me out every time. Can't the cameras detect feet and keep their distance?

If you want to know what hell is, I'm debugging a tree-sitter external scanner, and the values in the _boolean_ valid_symbols array eventually spell "markdown" in ASCII.
those should all be either 0b00000000 or 0b00000001.
I'm back in 1993-era buffer overflows. Great!

I hadn't come across this essay until now. It's very, _very_ good, and you should read it.
(minor: I can't help but wonder what a wank analysis would say about the essay itself, right around the Clausewitz reference.)
Still, the first 2/3rds are truly excellent. Again, go read it if you haven't.

like i dunno i know a lot of yimbys, i participate in local yimby group events, the idea that we're swimming in venture capitalist cash is just crazy. it's just delusional. it is, in the technical sense, wank:

Do you use homebrew? PSA!
Something on homebrew decided to add this gem of a line to my .zshenv:
echo 'export PATH="/opt/homebrew/bin:$PATH"' >> ~/.zshenv
Apparently I started a shell 6500 times before realizing this problem. (Guess how I knew the number)
I'm just speechless.

Look you can’t convince me that some of the truly wild good bell labs stuff (like, say, S) isn’t at least in part from acid.
I met some old bell labs people, is all I’m saying
