Show HN: A Full-Stack Web Framework for Go
Hey HN! I want to share my side project with you. It's called Bud and it's a full-stack web framework for Go.<p>I created a short video to show you how to create a minimal Hacker News clone with Bud: <a href="https://www.youtube.com/watch?v=LoypcRqn-xA" rel="nofollow">https://www.youtube.com/watch?v=LoypcRqn-xA</a>.<p>The framework is free, open source and MIT Licensed. You can find it on Github: <a href="https://github.com/livebud/bud" rel="nofollow">https://github.com/livebud/bud</a>.<p>I started working on Bud 2 years ago after watching the introductory Laracast videos about the Laravel web framework. I was just blown away by how productive you can be in Laravel. However, like many of you, I've been so spoiled by Go. I didn't want to go back to writing PHP, so I decided to try creating Laravel for the Go ecosystem.<p>At this point, I just had the following goal:<p>• Be as productive as Laravel in a typed language like Go.<p>I got the first version working in 6 months and tried building a blog from it... It fell flat. You needed to scaffold all these files just to get started. If you're coming from Rails or Laravel you may shrug, this is pretty normal. Unfortunately, I've also been spoiled by the renaissance in frontend frameworks like Next.js. What I love about Next is that it starts out barebones and every file you add incrementally enhances your web application. This keeps the initial complexity under control.<p>With these newly discovered constraints, I started working on the next iteration. Bud should:<p>• Generate files only as you need them. Keep these generated files away from your application code and give developers the choice to keep them out of source control.<p>• Feel like using a modern JS framework. This means it should work with modern frontend frameworks like Svelte and React, support live reload and have server-side rendering for better performance and SEO.<p>With these new goals, the Bud you see today started to take shape. But along the way, I discovered a few more project goals:<p>• The framework should be extensible from Day 1. Bud is too ambitious for one person. We're going to need an ambitious community behind this framework.<p>• Bud should be able to provide high-level APIs for developers while compiling down to performant low-level Go code for production.<p>• Bud should compile to a single binary. With platforms like Fly.io and Heroku, these days it's easy to not care about this, but I still cherish the idea that I can build a single binary that contains my entire web app and secure copy it up to a tiny server that doesn't even have Go installed.<p>It's still super early days. You can find the the Roadmap on Github: <a href="https://github.com/livebud/bud/discussions/9" rel="nofollow">https://github.com/livebud/bud/discussions/9</a>. I encourage you to contribute your thoughts.<p>And here's the current documentation for what's already in Bud: <a href="https://denim-cub-301.notion.site/Hey-Bud-4d81622cc49942f9917c5033e5205c69" rel="nofollow">https://denim-cub-301.notion.site/Hey-Bud-4d81622cc49942f991...</a>. Comments are enabled for anyone to chime in.<p>I have big plans for the framework. I hope you'll join me on this journey to build ambitious websites faster with Go!
Show HN: A Visual IDE for React
I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!

Show HN: Paperd.ink – an open-source e-paper development board
paperd.ink (<a href="https://paperd.ink" rel="nofollow">https://paperd.ink</a>) is an open-source e-paper development board. We wanted to build something with e-paper given its low-power nature and beautiful, high contrast display which complements your environment and is easy on the eye. Thus, we started working on something to be developed along the lines of Arduino, Raspberry Pi’s open-source ecosystem.<p>paperd.ink has a 4.2” e-paper display comes mounted on the PCB which we have designed to be a general-purpose development board suitable for your projects and applications. You can sync calendars, set up your home IoT dashboard, get to-do lists, and notifications, display art, etc. We have used an ESP32-based microcontroller with WiFi, Bluetooth, and microUSB connectivity. The board can be programmed in Arduino IDE, micropython, or ESP-IDF, you can check out the documentation at docs.paperd.ink. paperd.ink is designed to be low power so you can charge the battery once and go on for months on it depending on the refresh rate. It’s suitable to display low to medium latency or static information. Every paperd.ink comes with a hand-polished, 3D-printed external enclosure.<p>The first paperd.ink prototype was first posted on Show HN (<a href="https://news.ycombinator.com/item?id=22340398" rel="nofollow">https://news.ycombinator.com/item?id=22340398</a>) and other related communities (Reddit, Hackaday, etc) a little more than 2 years ago. We had a landing page, a short video of the prototype, and a user survey form asking a couple of questions along with a “Would you like to be a part of the waitlist?” question in the end. We got quite an interest from everyone on it so we decided to move ahead.<p>After receiving a positive response to the prototype, the next step was to figure out how to actually bring the product to the real world. We had no upfront capital required for manufacturing so we decided to do a crowdfunding campaign (finding a platform supporting our country India was another issue). At the same time, the pandemic happened which delayed everything because of unfeasible component prices, supply chain issues, and lockdowns everywhere. After researching thoroughly and formulating a production plan and figuring out unit economics, we launched the crowdfunding campaign roughly last year and had the 2nd Show HN post (<a href="https://news.ycombinator.com/item?id=27331311" rel="nofollow">https://news.ycombinator.com/item?id=27331311</a>). In the course of promoting the campaign, we got in contact with FOSS United which is a non-profit foundation that aims at promoting and strengthening the Free and Open Source Software (FOSS) ecosystem in India. FOSS United offered us a grant and that’s how we survived despite failing to achieve our crowdfunding target goal (we had ~40%).<p>After accepting the grant, we tweaked the PCB a bit and redesigned the external enclosure to make it ready for production. Scouted for manufacturers, suppliers, and shipping agents. Samples were ordered and tested. Test criteria and SOPs were exchanged. Vacuum casting (or any other method of manufacturing) of the enclosures was out of the question given the high NRE cost and high quantity needed to be manufactured, so we 3D printed them. Finally, the first batch was ready in the inventory to be shipped. All the orders received until now have been shipped and users should start receiving them shortly. Thanks to the HN community and our early supporters for everything. And special thanks to Daniel (moderator) for helping with the post. We plan to get feedback on the first batch and then decide on how to move forward. Please feel free to ask any questions!

Show HN: Oldest Search – Search for the oldest result on internet
Oldest Search is a custom google search that specifically targets the oldest entries available. I'm always curious about the first entries for certain data on the internet, it's a valuable perspective builder.<p>I personally like news articles that have been digitized that were written in the pre-internet era. Unfortunately some results don't always work well because pages have been dated incorrectly. For example, searching "Covid" shows recent results.<p>I launch new projects like this daily: small tools to increase human agency. I'm also very open to suggestions to improve!

Show HN: Weron – A Peer-to-Peer VPN Based on WebRTC Written in Go
Hey HN! I just released weron, a P2P VPN that uses WebRTC for transport which I've been working on for the last couple of months. It can create both layer 2/Ethernet and layer 3/IP overlay networks, and the underlying transport layer can be easily embedded to write your own P2P apps with Go. Compared to for example Tailscale, WireGuard and ZeroTier, its much harder to block on a network level and also significantly easier to set up, while not sacrifing much performance.<p>I'd love to get your feedback :)
Show HN: I made a browser-based RTS game
I've posted this game here before, hopefully a repost is fine as the game has changed quite a bit (improved AI, improved mapeditor, much quicker gameplay, etc).<p>Game is based on JavaScript/Canvas and WebSockets. On the browser side the map is pre-rendered (as a background image), just the mobile units/buildings and animations are dynamically rendered. The lobby server is made in node.js, but the game server is C++ for performance reasons (mainly the pathfinding). I found the C++ WebSocket libraries out there to be too difficult to use so I made my own based on the rfc. Overall I think making a game like this is quite easy with the browser performance/features nowadays. The game server and client side JavaScript are around 5000 lines of code each.<p>If you have any questions about the tech I'm happy to answer them.

Show HN: Tetris, but silly
Hello HN!<p>You can read this [1] blog post if you want to know more about some ideas that I have for this thing.
This is just an experiment right now, there isn't any real game (yet).
Any feedback would be appreciated, do you think this could become something that would be fun to play?<p>[1] <a href="https://unit520.net/posts/dead-trees-an-absurdist-block-laying-game-prototype/" rel="nofollow">https://unit520.net/posts/dead-trees-an-absurdist-block-layi...</a>
Show HN: Find the 10 highest and 10 lowest correlations to any stock
During the start of the year I was thinking how could I bet against certain stocks (in my case mainly Tesla) without using derivatives and the risks that come with them.<p>After I had success betting on the oil price with a highly correlated investment fond, I came to the conclusion that negative correlations could be used to bet against the price of other assets. Unfortunately, it is not easy to find correlations between assets if you don't know which assets to compare in the first place.<p>So I created a website where you can find the 10 highest and 10 lowest correlations of certain assets.
Show HN: I am building a free version of Strava
I recently added a Segments feature to the Hangtime mountain biking app for Android and IOS. If you are familiar with Strava’s segments, this new feature works much the same. For example, you can add a segment to an existing recorded ride by simply defining a start and end point for the segment. Once the segment is created, it will match any new rides, and optionally “back match” all previous rides. If a segment matches a ride, you you will see your time to complete that segment as well as your personal record (PR) and king of the mountain (KOM) for that segment. The KOM represents the best segment time amongst all riders that have matched that segment. You can also open the segment to see your complete history on that segment to gauge how your performance has changed over time. Some screenshots and videos as well as other features at the link below.<p><a href="https://mtbx.bike?page=hangtime" rel="nofollow">https://mtbx.bike?page=hangtime</a>
