    I wrote a lil' app to provide a fast, uniform, search-based UI: (I got tired of every app implementing its own tabs.) Works with OS X windows, file system, browser tabs, history, Emacs buffers, VSCode, etc.

    That wonderful feeling when you realize a book was written by an practitioner. Need a few picofarads to short high frequencies across a large gain resistor? Just twist some wires across the leads and trim to flavor. (From Johnson's "Photodetection and Measurement")

    The "Reltron" relational database GUI exploration system I did with Jamie Brandon last year () was heavily inspired by Eirik Bakke's work, which appears to be morphing from solid academic research into broadly usable product.

    Bay Area friends: Any of y'all have HTC Vive Lighthouse(s) I could borrow? I'm starting a new project w/ sub-millimeter positioning needs and want to test feasibility before sourcing a bunch of hardware.

    For example (in decimal), say we have a smooth gradient: the first pixel is 99 (white), the one under it is 98, and so on down to 0 (black). Switching the byte order is like switching the ones and tens place --- pixels were written 99, 89, 79, ..., 09, 98, 88, ..., 08, 97, ...

    Figured this out: PNG expects pixel values to be in network byte order, but I was writing them out in my CPU's native notwork byte order. In retrospect, the stripes are a clear giveaway.
