That's weirdly correct! I lived in Portland for over 10 years, and now I'm in the Boston area.

And here it is with most of the supports removed. "A warsworn is an animate mass of corpses composed of dozens, sometimes even hundreds, of victims of battle."

I've discovered that ReScript's pattern matching can help create unit tests that are easy to understand when something breaks.

ReScript has an experimental syntax to make working with Result and Option easier. On the left are nested switches, and on the right is the `let?` syntax. Inside of an expression you code for the happy path and it will bail on None or Error. github.com/rescript-lan...

I updated the text on the ReScript site to state that AI is great w/ ReScript. I've been working with codex/Claude across projects, and making changes in ReScript code produces consistently good results. Strong types, fast feedback, and a simple syntax make it a perfect fit for agentic coding.

This is amazing.
I’m thrilled to share that I’ve officially made the switch to ReScript! 🚀

While TypeScript has its place, the type safety and performance I’m seeing with ReScript are absolute game-changers for scalable development. It’s all about choosing the right tools to drive innovation and excellence. 💡

Has anyone else in my network explored the power of ReScript? Let’s connect and discuss the future of functional programming! 🤝

It's great to see ReScript growing steadily!

I whipped up a little script to create typed routing for @reactrouter.com and @rescript-lang.org. So if we delete or move a page that we link to somewhere else on the site, it'll become a compiler error. Strong types FTW!

This was my little man, Boba Fett. I had him for about 9 years and he had a chronic heart condition that should have killed him much sooner, but the lil bastard refused to die and survived several heart failures before I had to let him go. It's been a few years, but I still miss him.

I'm wrapping up my trip to Vienna to attend the ReScript contributors retreat. I met some great people, wrote a lot of documentation, complained about Typescript, talked about Rust and Zig, and had some amazing food and beer.

I've been working on extending my collection of modular dungeon tiles. Here's a door I just finished making this morning. I'll be using it for Pathfinder on Saturday, and if all goes well I'll make another 10 or so next week.
