retirement calculator I've been working on:

- lets you replay historical S&P data to calculate returns
- lets you use a range instead of a single value for a field
- calculates effective tax rate for you
- works well on mobile

Recent I'm working on: using computer vision to make a fishing game for my son, where he can move a net and catch fish. Right now I have a bunch of dots on the screen that I can erase by moving a piece of paper around.

🖥️🧑‍🤝‍🧑 After a delightful sabbatical, I'm slowly starting to look for jobs. Do you like where are you at work? If so I'd love to hear from you! I'm looking for work that is fun and impactful, working with a good team. I'm guessing most places aren't hiring till after the holidays at this point, so I'm just looking to chat and hear about interesting roles 😃

@adit thanks for all the sheep. You made me think for a few late night hours.

New blog post: the Monty Hall problem in pictures I read the solution for Monty Hall years ago and understood it, but this is the first explanation that has really clicked for me. I think this is a really fun post that shows how counterintuitive probability can be!

Any probability fans here? New blog post dropping shortly

This literature clock is the most wonderful thing I’ve seen in a long time. Checking the time becomes a moment of pure joy 😍


This is the teaser, full interview in a couple of weeks

I got interviewed about Grokking Algorithms! The interviewer is the wonderful Gabi O'Connor, a fellow Etsy employee

This is an old project, but by some miracle it's still working and I woke up this morning wanting to celebrate the things I love more.

This Inkplate e-ink screen shows Conway's Game of Life, seeded from tarpits I have on the Internet. The tarpits are programs on my computer that superficially look like insecure Telnet and Remote Desktop services, but actually exist to respond super slowly and make bots scanning the Internet 'get stuck'.

When a bot connects to the tarpit, the data it sends gets squished into a 5x5 grid and 'stamped' onto a Game of Life board. Data from a bot at the IP address 1.1.x.x will get stamped on the top left corner, data from a bot at 254.254.x.x will get stamped on the bottom right corner.

Conway's Game of Life, a set of simple rules that govern whether cells should turn on or off, updates the display once per second. The result is that bot attacks end up appearing as distinct 'creatures', that get bigger and more angry looking over time (as their centre is updated with new data). After the attack finishes, the 'creature' eventually burns itself out.

Despite that description, it's a really chill piece of art that doesn't draw too much attention but I can happily watch for a long time.

Credit for the idea goes to @_mattata, I had been wanting to make a real-life version of XKCD #350 for years before seeing his Botnet Fishbowl project.

This last week on the internet has really felt like going back fifteen years, and I mean that in the most positive way possible

The web app icon for Mastodon doesn't look great in the macOS dock, so I made some replacement icons based on the original artwork!!AupbcwNRole8gvV-1n

How to use: Command-click on the Mastodon web app in the dock to show it in the Finder, Command + I to open App Info, then drag one of the downloaded PNGs onto the icon at the top left.
