A Curried Composition Puzzle
In this short post, I’d just like to share a little puzzle that I assigned as an exericse while TAing for a functional programming class last spring. It’s a cute problem, but it haunts me. It’s the kind of problem that still keeps me up at night, months after I’ve solved it. Here’s the puzzle, […]

8 min read Allison Marsh is a professor at the University of South Carolina and codirector of the university’s Ann Johnson Institute for Science, Technology & Society. In the receiver for Baird’s televisor, electrical signals modulated the brightness of the neon tube [left], which was captured by the spinning Nipkow disk [back] to re-create an […]
GPU Debug Scopes
Rendering APIs these days tend to capture their gpu workloads into a serialized form such as a command-buffer or command-list to be dispatched at a later time into a work-queue. Diagnostic tooling such as RenderDoc or Nsight-Graphics allows the disecting of these command-buffers, but it’s not very obvious to determine what is happening at a […]
Fixing an Elgato HD60 S HDMI capture device with the help of Ghidra
This post has a little bit of everything. Hardware diagnostics, some suspiciously similar datasheets from two separate Taiwan chip manufacturers, and firmware reverse engineering. Read on if that sounds like fun! Lately, I’ve been enjoying watching random electronics repair channels on YouTube. There’s something oddly satisfying about watching someone take a broken device from totally […]

What are the best options for Amazon SDEs thinking about leaving over RTO policy
You join a union, or you join a different company. Or you threaten to, at any rate. Understand your leverage: job marketplace bargaining power stems from your willingness and ability to do the latter, while structural bargaining power stems from your willingness and ability to strike and/or engage in sabotage.
Why to Not Write a Book
A discussion of why I don’t intend to turn Gwern.net into a book, and how trying to write a book can harm writers. Along with asking about doing podcasts, people sometimes ask me whether I am going to write a book or turn Gwern.net into a book. To their surprise, I have no such intention. […]
