Show HN: Transitive, an open-source framework for full-stack robotic software https://ift.tt/rnmfF6I

Show HN: Transitive, an open-source framework for full-stack robotic software After three years in development, I'm thrilled to share Transitive: an open-source framework for full-stack robotic software ( https://ift.tt/2yzOd7T ). The Transitive framework makes it easy to build robot cloud portals. Even given all the great open-source tools for web development and device management, building such cloud portals for robots is still not an easy task. There are several reasons for this, but a big one is that robots are different from regular servers, despite many people attempting to tread them as such. They go offline a lot, have limited network bandwidth, and each robot in a fleet may run a different version of software and require a different configuration. Robots also generate a lot of data, some of which needs to be synced in real-time with cloud and web front-ends for processing and visualization, some of which recorded, and some discarded. In addition robots roam insecure areas and are connected over networks outside of the control of the startup, hence requiring tight authentication and authorization. Transitive solves many of these issues. It provides a reliable, real-time data synchronization protocol that operates on top of MQTT, called MQTTSync. MQTTSync seamlessly synchronizes stateful data between robot, cloud, and web, instead of just passing messages. It provides the notion of full-stack packages that implement encapsulation and versioning of software components for all three systems (robot, cloud, and web) and uses MQTTSync's name-spaced data model to reliably communicate and operate, even when different robots run different versions of the package. The robot and cloud components are run in sandboxes to isolate them from the rest of the system, and the web components can be embedded in any web page including existing robot cloud portals. And of course, all this is secured, using SSL for transport-level security, client certificates and JSON Web Tokens for authentication, and authorization based on MQTT topics. Taken together this lays a solid foundation for building new full-stack capabilities with ease. Note that Transitive is not a replacement for ROS, and in fact many of our capabilities run ROS nodes on the robot. Neither is Transitive a fleet management system. It just makes it easy for you to build your own! To learn more about our first release of the self-hosted version, please see the linked blog post. If you just want to try it out quickly please go to https://ift.tt/grEFXTt to create a free account, which will also give you some starting credit for try out any of our premium capabilities, such as webrtc-based video streaming, our web-terminal, or file-sync ("Dropbox for robots"). I'll be watching this thread for responses, or you can use the contact info at the bottom of the blog post to get in touch. Would love to hear your feedback! https://ift.tt/ZNqxIB6 January 17, 2024 at 11:50PM

Show HN: Browser's internal local routes containing juicy stuff https://ift.tt/9d8kl7m

Show HN: Browser's internal local routes containing juicy stuff There are internal local routes inside browsers which are used for debugging purposing by developers but one can find a use case for him selves. Play around with it to find something interesting. Here are those internal routes/urls corresponding to the browser. Put it in url bar (omnibox/search bar) and hit enter. chrome - chrome://chrome-urls/ firefox - about:about edge - edge://edge-urls/ I'm pretty sure that most of the browsers have this you can just google like this "[your browser name] internal urls" https://ift.tt/YQ1o07W January 17, 2024 at 01:15AM

Show HN: I made a visual editor for GitHub Actions workflows https://ift.tt/GivCLAF

Show HN: I made a visual editor for GitHub Actions workflows Hey there, I have always been a fan of GitHub Actions workflows but for some reason never liked YAML files as being the assigned file format for non-linear workflows. While YAMLs are great as configuration files, they can be quite tedious when it comes to creating, reviewing, and maintaining workflows. To solve this, I created a visual node system that makes the workflow creation and maintenance process more efficient and intuitive. It's a straightforward node engine with an UI editor. Examples for such a node graph are here: https://ift.tt/YCxmlWz... and here: https://ift.tt/zP4hwQ7... . For clarification, they are directly executed on GitHub runners. These graphs took me minutes to build in order to focus on my actual project. The next time you create a new repo, give it a try. Love to hear your thoughts! Thanks! https://ift.tt/jXJOTaA January 17, 2024 at 12:50AM

Show HN: A minimal working Rust / SDL2 / WASM browser game https://ift.tt/yWKJ3TG

Show HN: A minimal working Rust / SDL2 / WASM browser game "Game" is a stretch, but I put together this repo containing a pure Rust app which uses SDL2 and compiles to WASM (and can be run in a browser). Older resources were a bit out of date and a bit too verbose for my purposes, so here's a minimal working example. https://ift.tt/HlVh47i January 15, 2024 at 08:19PM

Show HN: BSON Extension for Postgres JSON support in postgres is superb but sometimes you really want decimal, date, and binary types, "carefree" UTF8 string handling (i.e. no escaping), and robust roundtrippability. So I made an extension for BSON. https://ift.tt/RrEtKjM January 15, 2024 at 07:16PM

Show HN: C port of the (non-super) Star Trek game, incl. WASM for browser/phone https://ift.tt/8Kv9pfL

Show HN: C port of the (non-super) Star Trek game, incl. WASM for browser/phone Hi HN, I've decided to port the original (non-super) Star Trek game to C since I wanted to try playing the original but wasn't able to find a lot of sources that run on modern machines. Therefore I based this port on Michael Birken's 2008 C# port. This is in contrast to the Super Star Trek game which was far more popular and has a number of sources available on the web. I took some hamfisted measures to allow the Web Assembly version of the game to be played on mobile as well, it's not very pretty but it kind of works. You can tap into the terminal to open your phone keyboard, then the terminal should be visible in the top half while the keyboard can stay open in the lower half. The tips section on the page has some further hints. The port itself is quite crude but I made sure that it is ANSI C89 compliant, because I wanted the game to be able to run on just about anything. For the best effect, I recommend playing the game using the aptly named cool-retro-term. https://ift.tt/9RqWpzn This is the best way to play short of hooking up your needle printer as a faux teletype terminal. https://ift.tt/ygHWLn0 January 14, 2024 at 01:25AM

Show HN: Conway's Game of Life, but with a gallery of other peoples patterns This is my spin on Conway's Game of Life. I have added the ability to create an account, save grids that you have discovered, and browse the gallery of grids saved by other people and replay them. This project has served as a sandbox for me to practice various aspects of developing a comprehensive web application from scratch. This was my first time developing a full scale web app with [almost] all the features you would expect. I know it is nowhere near perfect in its current state, but I feel it has reached a point of diminishing returns, and therefore my time is better spent focussing on other projects with more potential. I may continue to develop this project further in the future just for fun. https://ift.tt/yaxmuGH January 12, 2024 at 01:42PM

Show HN: I built yet another ChatGPT Chrome extension https://ift.tt/KY7nQhb

Show HN: I built yet another ChatGPT Chrome extension Hey HN, I’m here to introduce you my first of hopefully-many-projects-to-come this year: ReadPal.ai, a chrome extension that let’s you chat with ANY web pages while browsing. Let’s first address the elephant in the room: there are tons of chrome extensions of sorts out there…Why did I choose to work on this? Over the years, I’ve had many projects started that never crossed the finishing line; and also many ideas that’s dauntingly ambitious that I never even started. So I chose this project, in the hope that its moderate size & scope can help me finally exercise the build→ship muscle. And I must say, it has served its purpose. I thought it would just be a weekend project, however, end up dragging it for months…With the pressure of the year-end and the free time in the holiday season, I finally got to the ship phase! During the process of building, testing, and beta testing, I came across two revelations about the product: - Having AI side by side with access to the same information as you is very helpful! It's not just about summarizing long research papers, but even simple day-to-day activities can benefit from it. e.g. asking “is this miso good for making ramen?” on a miso product page on amazon, etc. - Despite a lot of similar extensions, there is still room for differentiation! The average user who isn’t intentionally following the developments in the AI field, can benefit from a tool that simplifies the complexity of various models & prompting techniques, and focuses on providing a user experience that seamlessly integrates with their workflows. There is still a long way to go in terms of the second point. Your feedback would be very helpful with that! Thank you!! https://readpal.ai January 11, 2024 at 09:03PM

Show HN: I built an affordable alternative to Spotify and YouTube Music Premium https://ift.tt/mCR4pid

Show HN: I built an affordable alternative to Spotify and YouTube Music Premium Hey guys, I had to cancel my spotify premium subscription which was a terrible thing once I like to listen music in loop while coding or at the gym. So I decided to code myself something cool to solve my own problem that makes possible listen music in loop and without ads. I took a night off and started coding something.. so that's how I built Youtube Music Loop. I know many ppl like to listen music but not everyone can afford to pay, so it's a lite affordable version of spotify and youtube premium, where you can: - Keep listen music without ads. - Synch your playlist through all your devices. - Listen music in loops and without ads. - Search for your fav music or just copy and past the link of youtube song (when search api doesn't reach its limit). - Get it as pwa / app in your phone home screen. - Works on pc and laptops, tablets and mobile devices. - Easy and simple to use, no fluffy stuff. It's an affordable option and you pay once and use it forever, which is more than half of youtube and spotify premium subscription price. You check it here: https://ift.tt/zv0Z9YD Let me know what you think and improvements you like to see, I have made many improvements as you can see here and here. -Fausto https://ift.tt/zv0Z9YD January 11, 2024 at 11:52PM
