I'm a Smalltalker in Javascriptland

I design and implement the lower levels of the Croquet collaboration platform, including the SDK and our server infrastructure. I give talks about it, and I maintain the servers. Yeah we're still a smol team 😅

Previously (and still in my spare time) I worked a lot with Smalltalk, the original object-oriented language. I was on Alan Kay's team for a dozen years and implemented Virtual Machines for Smalltalk-78 and Squeak in JS.

Published a blog post
Croquet launched publicly a few days ago.

Here’s my blog post about what our tech actually is.

Like, how we run a virtual server on each client, so your code and data never leaves the client, and still stays in sync.

Frontend-only multiplayer.
Unlimited Bandwidth.
Or: What is, anyways?

Excited to move to California for Croquet! ✈️

Croquet is a reincarnation of our early 2000s real-time collaboration tech based on replicated computation. It allows you to write multiplayer web apps without any server-side code, while providing end-to-end encryption.
