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.

(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!

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.

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?
