Show HN: Matic: A reimagined robot vacuum that actually works
13 by navneetdalal | 0 comments on Hacker News.
Hello HN friends, We’re Matician, and here’s why we built Matic. We wanted to live in an always clean home but were tired of always cleaning. We’d spend hours cleaning, but with kids and pets, the floors never stayed clean for long. We tried all the various robovacs, but they actually made things worse. They chewed up wires, got lost searching for the dock, and one even tore up an expensive rug after getting stuck on it for an hour! And we weren’t the only ones — friends and family had similar frustrations. So we decided to build something new from the ground up. Something that would just… work. As it turns out, robovacs are chock-full of sensors. Some actually boast about this in their marketing, leading customers to believe that sensors mean sophistication. But we live in homes built by humans and for humans, and humans don’t have Lidar or radar. Instead, we have an incredibly powerful perception system: two eyes and a brain. So, we decided to build a robot that sees like a human, so it can clean like a human. We gave the robot eyes (RGB cameras) and built its brain (state-of-the-art algorithms). We developed a simultaneous localization and mapping (SLAM) system from scratch, enabling the robot to build a photo-realistic 3D map of a home, move around with precision, and always be able to locate itself. Visual input also meant we could develop semantic understanding, so the robot actually understands what should be cleaned and what should not be cleaned. And we doubled down on privacy along the way. From day one, we committed to processing all data on the device, so that no video or audio ever leaves our home. This was hard to do, but it was simply non-negotiable. We shouldn’t have to sacrifice privacy for convenience. And we didn’t stop with the software. We also built purposeful hardware to take full advantage of the powerful perception system, working together to optimize cleaning. This meant reinventing the vacuum and mopping system from the bottom up and tightly integrating hardware and software for super-effective cleaning. It took some time to get here (5 years, 6 months to be precise), but we’re proud of what we’ve built in Matic. We are super excited for you to use Matic yourself and genuinely hope it makes chasing that “always clean” feeling a little more effortless. We look forward to your feedback and questions.

Show HN: WallStreetGPT:ChatGPT plugin for connecting to brokerage and trading
3 by nextworddev | 0 comments on Hacker News.
ChatGPT Plugins are in developer alpha, but thought to share one. WallStreetGPT allows you to: 1) Fetch real time quotes (crypto or stocks) 2) Get analytics 3) Do portfolio optimization (Markowitz, etc) 4) Submit live orders (yes.. but need a brokerage account that has API connectivity like IB or Alpaca)

Show HN: A Mental-Health Driven Social App with a Built-In CRM
2 by clseeley1 | 0 comments on Hacker News.
Hey HN! My name is Connor and I am posting today to launch (aka gather feedback on) the app I have been working on. I have General Anxiety Disorder. And that’s most definitely the first time I’ve written those 5 words out like that. My anxiety, very luckily, has never been that detrimental to my life, but I would be lying if I told you I didn’t notice it. For me, anxiety manifests as the inability to recognize negative thoughts quickly. When I fail to recognize them, they cycle and loop and I convince myself of things that aren’t true (that person doesn’t like me any more, I don’t deserve anything I have, I’m a massive failure with a too big nose and receding hairline, etc…). Over the years, I have done many things and learned many techniques to benefit my mental health, but one strategy has always been the most helpful: Talking to someone. Anyone. About anything. Anxiety is like a little voice in my head. When I talk to someone, it gets a lot harder to hear it. And it really doesn’t matter what we talk about, either. About their day, about mine. About my problems, or about theirs. My friends just make me feel better. Over the last five years, the missions of most major social platforms have shifted. They have chosen to prioritize entertainment and average-user-screen-time over closeness and relationships with friends. Such social media aren’t bad or wrong. I still use social media every day. They just don’t do a very good job of keeping me close to my friends. That's why I built WuzzUp?. To fill the void, and help me keep in touch with my friends and reduce my anxiety. I'd love to hear what you think!

Show HN: Rust Guideposts – 100+ topics to help learn about Rust
2 by jph | 0 comments on Hacker News.
I'm teaching Rust to compsci students and recent grads who are joining tech teams. I'm creating a guide of many Rust topics and their summaries. https://ift.tt/cHmtfqn The guide is free and open source. I'm seeking ideas for improvements, to help newcomers to Rust and its ecosystem. In addition to the repo, the guide is available as an ebook PDF, with pay-what-you-wish pricing. https://ift.tt/LqJ1wSl My goal is to help many people learn about Rust, so I greatly appreciate your advice and you sharing the guide if you wish. Thanks!
