Ask HN: Who wants to collaborate?

I was thinking it would be nice to exercise in VR, but I would have to pick something aerobic I wouldn't mind doing blindfolded, which rules out a lot, but I think a row machine could work.

So I'm imagining a pacific-island-navigate-by-the-stars simulator, maybe speed up time so 8 hours of night become 30 minutes of cardio. Choose a couple of islands to row between, get some directions of which star to follow, and get to work.

Good news: some water simulation and a night sky are probably just a library include away, right?

Bad news: would have to do something fancy to nail the motion sync, I was thinking an arduino and some hall effects, really just need to capture the bookends of each rep and adjust the video to match your movement. I guess goggles already do position tracking but I think I would basically want to predict the snap when you change directions, as even a few ms lag will ruin the immersion.

Alas, I am merely a web developer without so much as a pair of goggles, but I think this will be a good starter project on account of not needing to create any assets. Godot looks very promising. If anyone else has VR-but-good-for-your-body ideas I'd love to hear them.

Wow, there's been a bunch of public work in this space since I started! I was aware of the Agoric Realms work that preceded SES, but haven't kept up with their progress. I looked over some of the current SES/Realms code, and didn't (quickly) find anything that can limit CPU or memory consumption of the untrusted code in the browser. I decided to base my efforts on QuickJS/WebAssembly because there's much less inherent risk and a greater guaranteed deal of control compared to any solution that shares a GC heap with the untrusted code.

FWIF, Figma's plugin system started out with Agoric's Realms shim and then switched to QuickJS after a security incident: https://www.figma.com/blog/an-update-on-plugin-security/

I volunteer for a healthtech charity building mobile apps to support HIV prevention.

Our first product, Preptrack, helps people to use PrEP, the medicine that eliminates the risk of HIV infection. It's live on the App Store and has a strong and active community of users who love what we do.

We're always looking to talk to software engineers who would like to do a little good in their spare time or as a side project.

Feel free to check out our website (https://preptrack.co.uk), our volunteers page (https://preptrack.co.uk/volunteering/engineer/) or shoot me an email (sam [at] preptrack [dot] co [dot] uk). I'd love to hear from you.

That's awesome. Thank you.

Please do think about it for the next couple of days and I will drop an email to you in the next 48 hours (I live in India). We can then decide how to take it forward.

Just curious: How long does an end-to-end crawl take and how much resources does the process consume (in terms of hardware/mem etc.,)?

I'm working with the OpenAir collective (https://openaircollective.cc) on open source DIY-friendly carbon capture machines. We've made some strides lately, but we need more hacker types to advance our research initiatives.

There are a variety of projects to work on, but I'm specifically interested in the electrolysis of CO2. I could really use help from anyone with a chemistry background or access to lab!

If you're interested, please reach out to me via my email or hit me up on the OpenAir discord.
