Show HN: I've built a child monitoring app with mitmproxy and WireGuard https://ift.tt/567zkR8

Show HN: I've built a child monitoring app with mitmproxy and WireGuard Hi! I've been working on a child monitoring service and I'd really appreciate your input on it. The structure of the service is pretty technically interesting. It sets up a wireguard VPN on the child's Windows account, and then routes the traffic to our server. From there, we use mitmproxy to break open the TLS, inspect the packets, and then re-encrypt them. Currently all images are passed through an ImageNetV2 model, and for sites like reddit or google, individual links/communities are analyzed and we remove the content if it violates the filters without impacting the overall browsing experience. Coming soon(ish) will be a 8B uncensored llama3 model, which will allow parents to create custom filters for filtering content. I've always felt like child monitoring systems are missing the bigger picture when it comes to content filtering. I certainly remember being a little kid (9-ish) and coming across adult content I shouldn't have been seeing, but I also recall encountering subreddits and other online groups that laid the groundwork for my personality, without my parent ever knowing what was happening. The fact that as a child, I declared I no longer believed in God before I stopped believing in Santa was not the result of being some super genius, but because I was regurgitating what I read on r/atheism as gospel. Parents need more control over what their kids see, and as the internet develops more mature communities child filters need to keep up. It is not enough to simply hope your kid turns out normal, because there are companies actively working against you. The service is $20 a month, although it's 50% off for the first two months while we're in early access. We also only do Windows at the moment, although I'd like to expand (especially to linux) later this year. Let me know what you think! https://ift.tt/nO0Cj3L June 30, 2024 at 10:44PM

Show HN: Pass in data to Visa and cut your credit card fee by 50% https://ift.tt/1LiovOU

Show HN: Pass in data to Visa and cut your credit card fee by 50% Here's how your business can save up to 50% on credit card fees. Credit card interchange fees are expensive. These fees are what the credit card networks like Visa and Mastercard charge the merchant (you) whenever your customer swipes their card. Stripe or your payment processor passes these fees onto you. To incentivize data collection, Visa and Mastercard lower your fees whenever you pass in transaction data like zipcode, sales tax amount, invoice amount, customer address, itemized purchased services or goods, and the list goes on. This is called L2 and L3 data, and you can pass this into Stripe (or your payment processor) to lower your credit card fees. Parsing invoices manually to provide L2/L3 data to Visa is a pain. But with Trellis, you can do this automatically within seconds for any invoice. Watch how we do it here: https://ift.tt/XSRmwjI... If you’re a business and you accept credit cards, you can cut your credit card processing fee in half. https://ift.tt/YSc8aKT June 28, 2024 at 02:30AM

Show HN: I built an indie, browser-based MMORPG https://ift.tt/FEDf9Z6

Show HN: I built an indie, browser-based MMORPG I've been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https://poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use gltf-transform for processing all GLTF files, compressing them, removing redundancies, etc. Node.js server - Uses express and socket.io to process game state updates. It keeps track of every client's game state and issues delta's at each game tick (currently 600ms). The client can send interactions with different objects. The server validates those and updates the game state accordingly. HTML/CSS/JavaScript/Three.js client - I use regular web technologies for the UI elements and three.js for the 3D rending on the browser. The client is responsible for rending the world state and providing the client with different interactions. All code is written in JavaScript which means less context switching. Performance seems to be good enough, and I figure I can always optimize the server code in C++ if necessary. I am currently running two cheap shared instances but based on my testing, they can likely support about 200 users each. This is a low-poly browser based game so it should be compatible across many devices. The data a user needs to download to play, including all 3d assets, is approximately 2 MB, even though there are hundreds of assets. Overall, it's been a fun project. Web development and open source software have progressed to the point that this is no longer an incredibly difficult feat. I feel like development is going pretty well and in a year or so there will be plenty of good content to play. https://ift.tt/u25GdiZ June 26, 2024 at 11:23PM

Show HN: Voice bots with 500ms response times https://ift.tt/NVmnpij

Show HN: Voice bots with 500ms response times Last year when GPT-4 was released I started making lots of little voice + LLM experiments. Voice interfaces are fun; there are several interesting new problem spaces to explore. I'm convinced that voice is going to be a bigger and bigger part of how we all interact with generative AI. But one thing that's hard, today, is building voice bots that respond as quickly as humans do in conversation. A 500ms voice-to-voice response time is just barely possible with today's AI models. You can get down to 500ms if you: host transcription, LLM inference, and voice generation all together in one place; are careful about how you route and pipeline all the data; and the gods of both wifi and vram caching smile on you. Here's a demo of a 500ms-capable voice bot, plus a container you can deploy to run it yourself on an A10/A100/H100 if you want to: https://ift.tt/m0upwDI We've been collecting lots of metrics. Here are typical numbers (in milliseconds) for all the easily measurable parts of the voice-to-voice response cycle. macOS mic input 40 opus encoding 30 network stack and transit 10 packet handling 2 jitter buffer 40 opus decoding 30 transcription and endpointing 200 llm ttfb 100 sentence aggregation 100 tts ttfb 80 opus encoding 30 packet handling 2 network stack and transit 10 jitter buffer 40 opus decoding 30 macOS speaker output 15 ---------------------------------- total ms 759 Everything in AI is changing all the time. LLMs with native audio input and output capabilities will likely make it easier to build fast-responding voice bots soon. But for the moment, I think this is the fastest possible approach/tech stack. https://ift.tt/m0upwDI June 27, 2024 at 03:21AM

Show HN: The Tomb of Nefertari [QV 66] Guided Virtual Tour https://ift.tt/0WxidSl

Show HN: The Tomb of Nefertari [QV 66] Guided Virtual Tour I 3d scanned the Tomb of Nefertari and am building this guided virtual tour, trying to bring in photogrammetry of artifacts that I've made at various museums. It crashes sometimes still on mobile devices. I wasn't able to take photogrammetry photos of the artifacts from the tomb in the Museo Egizio in Turin because they were traveling while I was there (and now the museum is closed to install a new roof anyhow), so I tried to include comparanda from other museums where I had scanned artifacts. I tested the same dataset with 3d Gaussian Splatting but that had lower resolution results for great complexity in frontend code and reduced performance on older devices. [3DGS tour: https://ift.tt/o49Qe5k... ] Moving forward, if anyone's working on the same idea, I didn't find a good path to monetization through web-based 3d content, so I'll take the high resolution photogrammetry of spaces into Unreal and switch to desktop and headset builds. For the distribution advantage of web-based 3d content, I'm hoping to test next a desktop or VR build that may be easier to sell to sustain my work. https://ift.tt/PHCjRZ5 June 25, 2024 at 08:18PM

Inspired by the rich narrative and intricate details, I decided to transform various parts of the story into demo tables, complete with text and images using https://tabulator.ai/ . The goal was to explore how AI can aid in the creative process and provide indie game developers and storytellers with some ideas quickly. https://ift.tt/YVoyztZ June 25, 2024 at 02:34PM
