I lived in CT during Sandy! We lost power for ~a week, school cancelled the entire time.

I’ve heard the JS sandy stories, pretty wild.

My first day at Penn, the Schuylkill flooded 16ft because of Hurricane Ida, and classes were cancelled.

I'm starting my new job on Monday, and so of course New York is expecting the largest blizzard in over a decade

The next iteration of NJPLS will be held at the University of Pennsylvania on 22 May 2026! If you'd like to attend or submit a talk proposal, check out the website for details: njpls.org/may2026.html

I'll probably relatively off social media as I navigate a big move & new job, but I would love to in-person connect with folks living in NY working on cool things! Ping me if you're in town.

Seems like a good time as any to say I'm:

(1) moving to New York next week, where I'll:
(2) be writing OxCaml at Jane Street!

Excited to start the next thing :)

Thanks, Anil!!

Thanks, Rachit!

Thanks David!

Successfully defended my dissertation today. Now Dr. Joe!

Still OCaml

Turns out it's a tiny fix. Not entirely sure how to test it. 🤷‍♂️

maybe I should just write the PR that fixes this

After some investigation, it seems like the oxcaml folks are already well aware of this

seems like this bit of the compiler is still in flux, and there are some sharp-ish corners. I ran into this codegen bug with unboxed bigstring accesses a few weeks ago while working on 1brc... you can cause a segfault with this if you try really hard

Hey, I'm looking for speakers at DC Systems for this year! Let me know if you, or anyone you know would enjoy giving a talk to an extremely nice and curious audience!

It’s called ‘vs code’ because the code is an enemy you are fighting

this fucking rocks

This one really bugs me

also, Applicative usually being defined in terms of (<*>) and not liftA2 was so incredibly damaging.

unfortunately not

try the audiobook it’s so much worse
