We built a self-healing system to survive a concurrency bug at Netflix

A counter-intuitive guide to better leadership
Intuition works from the shadows. Look at it directly and you get rationalization, not explanation—the verbal brain fills the gaps with a plausible story.

Google banned me from Google Voice
After 15 years, Google banned me from Google Voice . This post is a summary of what happened, with the hope that it might help someone in the future who runs into the same situation. At the end , I have some thoughts about the latent danger of being banned from Google at any time with no notice.

A mistake that killed Japan's software industry? (2023)

Bringing Faster Exceptions to Rust
Three months ago, I wrote about why you might want to use panics for error handling. Even though it’s a catchy title, panics are hardly suited for this goal, even if you try to hack around with macros and libraries. The real star is the unwinding mechanism, which powers panics. This post is the first in a series…

All the data can be yours: reverse engineering APIs
I’ve built a lot of unofficial software for my schools, Brown University and previously Macalester College. To name a few: an “everything app” called 75grand with dining hall menus, Moodle assignments, building hours, an event calendar, and more; two unfinished course catalogs; and a university shuttle tracker. None…

Tracker Beeper (2022)
A week ago, I finally got round to implementing an idea I’d been toying with for years: what if your computer made a little bit of noise every time it sent data to Google? From studying logs, I’d long known just how many sites send all your visits and clicks to (at least) Google, but a log that you have to manually…

Using Two ReMarkables
I'm a PhD student currently, which means that I spend most of my work life reading, or thinking about what I should read next. The timelines for my reading schedules range from what I need to read before a class or meeting next week, to what I ought to read for a paper or research trajectory that won't have any…
