Decentralized browser-based P2P E2EE messaging.
The key detail that sets this apart from other messaging apps is the browser-based client-side cryptography philosophy.
No need to install anything. Your ID is crypto-random and so the app doesnt need to rely on any central registration system like phone numbers. Your ID is unguessable and to connect to someone, you have to explicitly share it.
WebRTC has other nuances like being to route through a shared network for secure/faster transfer.
I hope this project has reached a level i can share the following details. I've made a genuine effort towards documentation and transparancy. I dont think it'll ever be enough and so im still concerned it isnt ready to share. While im using AI throughout. This is not a vibecoded project. There is attention throughout for unit tests and formal-verification. With your feedback, id like to make improvements for clarity throughout.
This version of the app demonstrates a fairly unique approach using a browser-based, local-only and webrtc approach. I know it's impossible for any system to be the "world's most secure", but that isnt a reason to not try. By rigorously implementing an exhaustive list of security features and practices, the aim is to get as close as possible.

This is intended to demonstrate client-side managed secure cryptography.

* [Roadmap](https://positive-intentions.com/docs/technical/p2p-messaging-technical-breakdown/)I know ive tried to compress a lot of my journey into one post. The project above is going to be tricky to understand. Feel free to reach out for clarity on any of the details.

🚀 Four #AI models walk into a bar, and order the same 4 apps: a raycaster, a Rubik's cube, a calculator, and Game of Life. 🤖🤦♂️ They each think they're special snowflakes with "fancy" names like Sol and Luna, only to realize they've all created carbon copies of the same tech demo—bravo for innovation! 🌟🎉

I'd like to share the latest version of my project.
It's a a decentralised P2P messaging app. The aim is of course privacy and security.
It demonstrates a fairly unique approach by using browser-based local-only storage with webrtc.

Ahoy, ye landlubbers! 🏴☠️ Prepare to be blown away by this "innovative" tech demo masquerading as a game, where the thrill of virtual wind physics is only rivaled by watching paint dry—except this paint is at sea, and it’s 8-bit. 🌬️ Apparently, 380k+ kilometers of digital water have been "sailed," proving yet again that people will do anything to avoid real exercise. 🚶♂️💨

Ah, the classic combo: “super fast” and “just a moment...” 😆 Because who doesn’t love waiting for their “speedy” tech demo to load? 🚀 But first, let us pay homage to our digital overlords by enabling cookies and JavaScript. 🍪

Want encrypted #WebRTC video calls with no downloads, no sign-ups, and no tracking?
This prototype uses PeerJS to establish a secure browser-to-browser #connection. Everything is ephemeral and cleared when you refresh the page—true #zerodata #privacy!

A lot has changed (and some things haven’t), but the experience remains next-level and mind-bending. From jaw-dropping spatial photos to new immersive features, I share what’s improved, what needs work, and whether this futuristic headset is finally worth it.
Check out my full review and let’s geek out together!

🎉🎮 Behold! Yet another mind-blowing demo from the powerhouse team of #Haujobb and #Sweet16. You can only watch this revolutionary tech marvel online (because, why make things easy, right? 😂), and it runs better on #Firefox... because #Chrome clearly wasn't enough of a challenge. 📉💻

Just rediscovered this video of a #TechDemo I built years ago for "3D Hockey". The idea was that you'd play #hockey in a massive glass capsule full of water in orbit around the earth. Players would have fins and swim around the stadium. Fans would get on an "audience orbital ship" that parks outside to allow them to watch. All other hockey rules applied, like off-sides and checking and etc.
I got pretty far with the demo, but struggled to find the fun.

Do you have a ReMarkable tablet, Toronto?
Please bring it to show off, and enjoy pizza with us! 😄🍕Why would we think this might work?
Last time we asked for a theremin -- and we got it!You can join us even if you don't have anything to show-and-tell, but it's more fun if you do!

Almost done with the porting for the game. A few bugs here and there, then we're back in business :D Exciting!
Meanwhile, here's a sneak peek / WIP of the tech demo being worked on (Godot 4). Tons of findings and things learned in the process. Things that will be of big benefit for the development of the game.

Woah, what did I just watch?! #NinjaGaiden scrolling craziness with a #TimCollins composition. This is so cool....whatever it is. #NES #TechDemo

Also of possible interest is an GBA ADPCM-like audio decoder + video codec rendering proof of concept.

here is a much older video from when I first got

20 years ago I wrote some blitters specialized for the GBA, I never ended up using the tech in anything but it was fun to write. Anyway here is a video of it in action.
If you are interested in trying out the ROM you can find it here. (last time I checked still worked on flash carts on actual hardware...)
