Learning Brazilian Choro and the 7-string guitar
More than five years here, and I'm still regularly finding things I didn't realize I'd lost. Like it will happen once every couple of months.

Don't let it happen to you!
The path back from burnout is so much longer than you can anticipate, and it gets harder the more it happens. Learning to be patient and kinder to myself has been a big process, and a year and a half later I'm still not back to where I once was.

My kingdom for eye tracking that clicks whatever window I'm looking at with multiple monitors. Particularly so in macOS, incapable as it is to remember the focus of the previous window thru Cmd-Tab.

10-yr-old bug, never fixed. good job everyone, I'm glad we gave half our lives to software engineers

(shot in the dark, but) any Quarto users familiar with formal methods who'd be willing to chat with me?

I'm cleaning up our yaml conf+validation system and trying to find the right model to characterize our system.

If you read "Ordered Monoid" or "Kripke Semantics" and think "fun", that's you!

I remember 'The Net interprets censorship as damage and routes around it'. Ah, the folly of youth.

cool self-healing packet-switching network architecture you’ve got there. Be a shame if something centralized it into a few discrete points of failure.

Another morning, another attempt to use Haskell seriously, another zero to GHC internal error in sub 10 minutes, in a trivial project.

For stuff like Typescript, I would be angry.

For Haskell, I'm just actually sad :(

Good morning! Text is easy! Today's agenda: are you a single quote or an apostrophe? Or:

'Tis the season to talk about these apostrophes' interpretations

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?
