About 40 people at a bar/restaurant in Culver City and it was great! Lots of interesting people. Great conversations but when it was over, I had no way to contact any of these people. So I started writing this bluetooth app. Using CBCentralManager on ios and BluetoothManager on android. Each phone broadcasts as a peripheral but also connects as central. Rooms full of phones running the app gossip.Think of the term "peripheral" as server and "central" as client. Yes there are differences in bluetooth and reasons for those terms, but my life got much easier thinking: client server. So in a room with just two phones, which one is which? It can't be a coin toss. If 50% of the time both phones act as the server and neither client, bad. Or if both phones act as clients, bad. So how do you break the tie?

Show HN: VivaChat – FaceTime with AIhttps://app.vivalabs.ai/chatTLDR: Video chat with realistic AI persons: https://app.vivalabs.ai/chatHey AI enthusiasts,After GPT’s Advanced Voice Mode launch, we’re more excited than ever about authentic conversations with AI. We think the next frontier will be incorporating video feeds.On VivaChat, you can video chat with an AI therapist, digital marketing consultant, English language tutor, or a tech recruiter. We’re also beginning to support business use cases around customer support, HR, and education.Building this was a blast! We strung together multiple systems to coordinate an entire conversation: ASR + VAD models to process user speech, LLMs to generate text responses, TTS providers to generate speech, and a custom video generation model to generate lipsynced video frames.The key technical challenges were achieving respectable visual clarity (HD quality) and reasonable latency (~1s end to end). We trained custom NERF (neural radiance fields) models to generate video frames consistent with the generated auSep 26, 2024 10:05 PM
