About

I am Henry Hu, a second-year computer science student at Northeastern University. Most of my experience is in building full-stack AI applications — the whole stack, from serving infrastructure up to the interface, with shipping the actual product as the point. Recently I have been getting into mechanistic interpretability and model internals: less about what a model outputs, more about what is actually happening inside it.

This site is a workshop notebook. I write here when I have something I have actually done and learned from, not just an opinion. The journal is for long-form notes — usually a writeup of a project, a paper I worked through, or a mistake I would like to remember. The links page is the dump of things I keep re-sending people. The about page is this one. Hi.

Interests

Poker

Poker is the cleanest version of the kind of thinking I like: incomplete information, noisy feedback, and a lot of pressure to separate the hand you wanted from the hand you actually have. I like the math, but I mostly like the discipline of making a decision and then not rewriting the story after the river.

Catan

Catan is less elegant and more chaotic, which is probably why it is fun. The whole game is resource timing, table politics, and pretending your sheep empire is a legitimate long-term plan. I like games where the optimal move still has to survive other people being annoying on purpose.

Dark and Darker

Dark and Darker scratches the same itch from the opposite direction: extract, risk the bag, and accept that one bad corner can erase twenty good minutes. It is clunky in ways that somehow make it better. The tension comes from how little the game protects you from your own greed.

Books I've Read

I keep a loose record of books I have finished because otherwise they blur together. I am drawn to books that leave some residue: systems books, history, philosophy, fiction with a spine, and anything that makes a familiar thing feel newly strange. The Brothers Karamazov is on that shelf. This should probably become a real reading log on the site.

Ballade No. 1

I am slowly learning Chopin's Ballade No. 1, which is a funny thing to write because "learning" here means getting humbled by the same few measures for a long time. It is too hard in the useful way: every section exposes a different weakness, and the piece only works when the technical parts stop sounding like technical parts. My god, getting the coda up to speed is brutal.
