Focus: game development & cryptography
Recently thinking that maybe game engines should ship default terminal multiplexer configs

Lots of times running the engine requires setting up multiple terminal window and it would be nice to have some pre-configured

Experimenting with this idea for our engine

You've probably heard about Midnight and Mina multiple times

But what are they? How do they give privacy? How can they connect to other chains? Why are they exciting?

I cover it all in my latest video + thread ↓

Made my first PR to @opentelemetry.io !
github.com/open-telemet...

Used this to build a Javascript-based log collector so that you don't need to run a docker contain just to aggregate logs on dev builds
refactor(otlp-transformer): json schema based validation by SebastienGllmt · Pull Request #5265 · open-telemetry/opentelemetry-js
Which problem is this PR solving? The goal of oltp-transformer is to provide JS-friendly (de)serialization logic for traces, metrics and logs However, currently, there is no deserialization logic (...

Sidequest Sunday: I wrote a library to generate beautiful colors from namespaces based on color theory

I call it material-chalk because all namespaces actually get a full Material Design compliant color scheme!

It turns out the math is super interesting with a really great final result! ↓

Wake up babe a new developer productivity update just dropped

Deno now supports WASM as a first class citizen! This should save a lot of headaches for Javascript devs trying to use crypto libraries

How it feels to work on wizardry combining multiple cryptographic techniques at once

Did you just follow me from my post on the other app?

Probably a lot of you have few followers still, so post below to find each other ↓

I'm a bit surprised there are no good Typescript libraries for dealing with generators

I does feel maybe unsolvable given generators are coupled with the custom scheduler you want, but it feels like there should be a middle ground between nothing at all and something specific like redux-saga

I feel like early BlueSky vibes are pretty different than early Threads vibes

Threads felt like a race to be the biggest degenerate possible since the algorithm liked that

BlueSky definitely has a lot more serious posts

I recently learned you can write opaque types in Typescript abusing the fact that Symbol keys in object are ignored in most cases and got really excited

Then I realized if everybody ships their own nominal types, I'm going to have to cast everything everywhere and now I'm not so sure about this

So many things in cryptography would be solved if we could just assume everybody has specialized hardware to handle it

It still boggles my mind that out of all the times where that's the case, TPM is the one where Windows 11 decided to force a backwards-incompatible change onto everybody

Somehow it always feels like every Typescript notation is 90% of the way to working and then you always have to wrap it with a hack in the end

My latest favorite is that you can't make a generator's `next` return type depend on its input type unless you make it a generator of generators🙄

Hey, new to Bluesky! I work in gamdev and cryptography!

Some of my favorite games:

🌎Earthbound
⬇️Undertale
🤔Life is Strange
👀 Before your Eyes
🎮 almost all SNES games honestly

Some shows I also like:
🔑 Clannad
✨ Madoka Magica
🫵 Nathan for You
🎭 The Rehersal

We built rock-paper-scissors where you can mathematically prove who won

This is useful in gamedev since it allows moving computation off the server and into the client without introducing vulnerabilities 👍

We'll keep working on it for our own games and share the tools for others to build with it!
