Some coworkers are committing to work overtime for a 1% bonus. The first part looked very promising but the code of his second part does not work and he hasn't uploaded a complete version of it to his github either. So I'm trying to get a vector with all senders/clients so I can just iterate through them and send the message to each one but this seems to be problematic. Next, we need to generate a public-private key pair which will be used to by Warp to serve the content securely. [ ] Build and use asynchronously or synchronous websocket clients.
