Show HN: Calculator for US Individual Income tax, from 1970-present I wanted to share a simple web app I created recently, which lets you estimate income taxes owed in the US: https://taxsim.app All the calculations occur directly in the browser, and are powered by a Fortran program that has been converted to WASM using emscripten. This calculator was originally developed in the 1970s [1] by the non-profit National Bureau of Economic Research. NBER has been maintaining this F77 codebase for the last 50 years, and uses it primarily for academic research on tax policy. The Fortran source code itself is over 1MB of text, because it codifies both federal and all 50 states' tax laws for each of the last 62 years. I first learned about NBER TAXSIM [2] a few months ago via an interesting paper they published "Automatic Tax Filing: Simulating a Pre-Populated Form 1040" [3]. The Fortran code itself is not open-source, but is available on request for research purposes. I reached out to NBER and proposed compiling it to WASM, so it could be run directly in a browser. With relatively little effort I was able to create a js/wasm version [4], thanks in huge part to previous open-source work [5]. This WASM build now powers https://taxsim.app, which is my attempt to create an interactive UI to allow for easier exploration of the US tax code. Specific tax scenarios can also be shared easily, by simply copying the browser URL. The code for this webapp is also open-source [6]. This was my first time experimenting with WASM, and I am already a huge fan. Not only was I able to take a 60 year old codebase and get it working on every modern browser and device, this work is also now benefiting the academic community. For example, the js/wasm can be run directly in V8, which means it can also now be run locally within R using libv8 [7]. Previously most researchers were uploading their tax scenarios to NBER's servers via ftp/ssh/http.

Show HN: ColorTiles Browser Game Hello HN! Here is a little game I made, colorful tiles must be placed next to other tiles and match in symbol or color. This game is inspired by Passage 3 and similar games like Qwirkle, Rummy or Dominoes. There exist some browser-based versions here and there, but I wasn't completely satisfied with any of them, so I made my own. This is optimized for a broad range of screen sizes and auto-rotates the playing field for narrow (portrait) viewports. As I've discovered with my own parents, folks who enjoy playing Solitaire, Hearts and similar games might enjoy this as well, so gladly spread the word. Have fun and feedback is appreciated! :) https://colortiles.net/ June 29, 2022 at 08:08PM
Show HN: Ploomber Cloud (YC W22) – run notebooks at scale without infrastructure Hi, we’re Ido & Eduardo, the founders of Ploomber. We’re launching Ploomber Cloud today, a service that allows data scientists to scale their work from their laptops to the cloud. Our open-source users (https://ift.tt/B8TZz16) usually start their work on their laptops; however, often, their local environment falls short, and they need more resources. Typical use cases run out of memory or optimize models to squeeze out the best performance. Ploomber Cloud eases this transition by allowing users to quickly move their existing projects into the cloud without extra configurations. Furthermore, users can request custom resources for specific tasks (vCPUs, GPUs, RAM). Both of us experienced this challenge firsthand. Analysis usually starts in a local notebook or script, and whenever we wanted to run our code on a larger infrastructure we had to refactor the code (i.e. rewrite our notebooks using Kubeflow’s SDK) and add a bunch of cloud configurations. Ploomber Cloud is a lot simpler, if your notebook or script runs locally, you can run it in the cloud with no code changes and no extra configuration. Furthermore, you can go back and forth between your local/interactive environment and the cloud. We built Ploomber Cloud on top of AWS. Users only need to declare their dependencies via a requirements.txt file, and Ploomber Cloud will take care of making the Docker image and storing it on ECR. Part of this implementation is open-source and available at: https://ift.tt/ibFNKDy Once the Docker image is ready, we spin up EC2 instances to run the user’s pipeline distributively (for example, to run hundreds of ML experiments in parallel) and store the results in S3. Users can monitor execution through the logs and download artifacts. If source code hasn’t changed for a given pipeline task, we use cached artifacts and skip redundant computations, severely cutting each run's cost, especially for pipelines that require GPUs. Users can sign up to Ploomber Cloud for free and get started quickly. We made a significant effort to simplify the experience (https://ift.tt/w5ryEsq). There are three plans (https://ift.tt/spylLUq the first is the Community plan, which is free with limited computing. The Teams plan has a flat $50 monthly and usage-based billing, and the Enterprise plan includes SLAs and custom pricing. We’re thrilled to share Ploomber Cloud with you! So if you’re a data scientist who has experienced these endless cycles of getting a machine and going through an ops team, an ML engineer who helps data scientists scale their work, or you have any feedback, please share your thoughts! We love discussing these problems since exchanging ideas sparks exciting discussions and brings our attention to issues we haven’t considered before! You may also reach out to me at ido@ploomber.io.

Show HN: I ranked news websites by speed I've been working on building "the fastest news website" for a few reasons: 1. I got tired of waiting for news websites to load, so I made a text-only news website that only has major news headlines. 2. I wanted to demonstrate to the world that if you want to build something really fast on the web, you can do it without loads of JavaScript. 3. I wanted to show that you can design something that looks good without having tons of images, etc. I put together the speed page at https://ift.tt/OGpbRSC to hold my website to be more accountable for speed, but it's also interesting to see how fast other news websites are (or in most cases, are not). Some feedback I'm interested in receiving: 1. What's your take both on the speed ranking methodology for Legible News? 2. Are my descriptions of the metrics for a non-web developer reasonable? Example of that at https://ift.tt/GSz7eXB , and if you click through the links on that table, you see a description like https://ift.tt/oGL5n9z Sorry ahead of time, but I can't fit all news websites on the speed report. I had to target general news websites, not ones for specific niches like HN for Tech. If there's something you think that's missing please post it, but I can't promise that I'll add it. If you like it, please consider subscribing! Thanks! https://ift.tt/OGpbRSC June 28, 2022 at 11:05PM

Show HN: Product Analytics in SQL with dbt Hey everyone! Like many data analysts and engineers, I love SQL and the dbt ecosystem. So it bothers me that we have to use separate tools for product analytics. We do our transformations, BI work, and ad-hoc queries in SQL, but when it's time to look at funnels and flows, we have to use (and procure) a separate platform like Mixpanel or Amplitude. This dbt package is a (very rough) start at fixing that. With it, you can create event streams and run funnel analyses via dbt[0]. More features like flows and retention are coming soon! But I'm mostly curious how you all are doing product analytics right now. Are you using a dedicated tool like Amplitude? What could be better? Do you want to do product analytics in SQL in the warehouse or would you rather it live somewhere else? Would love to get your thoughts, and thanks for taking a look! --- 0.

Show HN: In-depth photographic look at all the golf courses I play I'm an avid golfer; it's my main hobby. I decided to start taking pictures of all the courses I play. While there's a lot of golf websites out there, none of them really try to document the courses in depth and look at each hole, along with the course facilities like the practice areas. I live in Chicago and am starting with the courses in this area (of which there are dozens of public courses to play). While I play golf, I take photos with my phone of every (relevant) aspect of the golf course I can think of. Then they're processed and organized on the website. Obviously I'm starting this journey on my own, and in that sense it's not scalable. I won't be able to visit all the courses in the US, let alone the world. I hope to find others that would like to contribute to the effort. At some point I'd like to add course news and histories to the site. Many golf courses in the US are over 100 years old and have rich histories. And of course many older courses exist in Europe. I also have started adding descriptions/commentary for each hole on courses. For example, see: https://ift.tt/LkMQ2Sp... And maybe went a little overboard on this one: https://ift.tt/Qn7tEsl... Anyway, it's a fun project and could go in a lot of directions. PS: I'm always looking to expand my golfing circle. If you're in Chicago and want to play sometime, hit me up -- contact details are on the website. https://ift.tt/mCLYO3P June 24, 2022 at 01:23AM
Show HN: Pragmatic Formal Modeling (Tutorial series with runnable examples) Formal modeling is a mathematical approach for designing and checking correctness of software systems. It focuses on standard software engineering and distributed systems problems of the sort programmers face every day. It takes a pragmatic engineering approach: each problem starts with UML diagrams, design decisions and sometimes even a requirements document. We work through how to get from a whiteboard design to an initial mathematical model. Then we refine it based on logical errors found by the model checker, which return with a level of detail unheard of in a standard debugger. Formal modeling is a skill every engineer should have in their toolbox. All the examples are downloadable, and their is a quick setup section at the start. Additionally, there is an explorable model error debugger build right into the website. https://ift.tt/I1V2cq5 June 22, 2022 at 11:13PM
Show HN: Crocodile - Better code review for GitHub Hi HN! I've been working on a code review app for GitHub called Crocodile for about a year. I used to work at Microsoft where we used a tool called CodeFlow for reviewing code and I missed it after I left. I know many other ex-Microsoft engineers feel the same. Here are some of the distinguishing features of Crocodile that are inspired by CodeFlow: * Comments float above the code instead of being inline. Long discussions that are displayed inline make it really hard to review the code. * Comment on any text selection in the file, even a single character. * Comments don't get lost when code changes. I hate it when comments become "outdated" because I rebase or the line is edited. I also implemented lots of features that I wish CodeFlow had which you can read more about on the blog. [1] For those curious about the tech stack: it's mostly written in Go with Alpine.js, HTMX, and Tailwind CSS for the frontend. For storage I use PostgreSQL, S3 compatible object storage, and Redis for caching. I use Pulumi for infrastructure provisioning and Kubernetes deployments. Everything is hosted on DigitalOcean. Feedback is welcome! [1] https://ift.tt/l7iBDLv https://ift.tt/GzUumHf June 23, 2022 at 01:37AM

Show HN: Effortless Authentication for Your Web Application Hey folks, Michael here. I have been working in this project on and of for about a year and a half and I finally got it into a state where I can share it. I initially started this project to learn Rust and afterwards decided to make it useful for others. Vulpo Auth is an authentication server that you can host yourself. The goal was to make it as easy as possible for you to get started and have a complete authentication solution without you having to configure anything. Project Website: https://auth.vulpo.dev The Project contains: - Auth Server (Rust) - Admin Dashboard - JS and react SDK - Prebuilt Web UI (currently react) (https://ift.tt/PQZXdk3) - rust SDK for rocket Some of the features: - Email and Password Auth - Passwordless Auth - Google Auth - Translateable Email Templates - Enable/Disable Sign In or Sign Up - Password Reset Flow - Update Email Flow There is still a lot to do, the code base is full of experimental ideas and there a bunch of things to clean up, but first I want to focus on writing documentation and guides before adding more features. Besides the missing documentation, what are you missing? June 19, 2022 at 10:38PM
Show HN: Remove Silence from Videos with Ffmpeg There was recently a Show HN for a program that lets one remove silence from video files [0]. I was almost certain that ffmpeg could do this... But after searching for it, it turned out I was wrong: ffmpeg can't do this out of the box, and also can't read input from an EDL file [1]. So I set out to write a solution, as simple as possible: produce a list of select filters that are applied to video and audio, and retain only the non-silent parts. The 'silencedetect' audio filter detects silences, and produces timestamps for when silences start and end. So one can pipe the output of that to a Python script, that builds an ffmpeg command with the appropriate select filters. The resulting ffmpeg command can be run to re-encode the video without the silent parts. Hope this helps. - - - Notes: 1/ I did find something somewhat similar to what I ended up doing [2], but it's complicated, and does the video encoding inside of Python. Granted, moviepy uses ffmpeg under the hood, but it's still better if ffmpeg does all the encoding directly. 2/ This solution doesn't produce a myriad of intermediary files that it would recombine afterwards; there is just one encoding of the output video file. 'silencedetect' is very fast, so all in all running this should be pretty fast.

Show HN: Soliciting post placement on Hacker News Hey, HN -- I just received the following email and I'm not sure what to do about it. Obviously I want to discourage requested-posting like this; is there some structured way that we can do that? One of the things I love about HN is how high the signal-to-noise ratio is relative to...pretty much the rest of the internet. I wouldn't ordinarily call someone out like this, but I want to innoculate HN against this sort of thing. ---- Hey doches, Not sure if it's conventional, but thought I'd ask anyway. Would you be open to posting about my product on Hacker News? I understand that similar to Product Hunt, HN gives higher priority to users with higher karma. I usually keep up with recent discussions via RSS feed on Feedly, but almost neve post. So I thought I'd reach out to someone that has authority.

Show HN: Lorblets, a Little Puzzle Game Lorblets is a little puzzle game I made: https://ift.tt/CTyAiWu Lorblets is a variation on Lights Out. The goal of Lorblets is to turn ON all the lights. Unlike Lights Out (typically a grid of black and white squares), Lorblets puzzles have complex shapes (and bright colors!). The puzzles in Lorblets are generated at random from a seed, and they grow in size as you progress. The code quality is...not great? The design leaves something to be desired. And the game itself is a bit derivative. So why am I sharing this? Because I want to celebrate having shipped a complete game - modest though it may be. I'm a 39yo who has long dreamt of one day making a game. And yet I've tended to put my software engineering skills to work doing everything except that. I've devised complicated game mechanics on paper. I've written multiple overly complicated game "engines" in JavaScript. I've daydreamed for countless hours about my magnum opus: a 3D simulated open world with a natural language interface, narrative generation, character customization, scene building tools, a modding system... Long story short, that magnum opus has been fun to tinker on, but has not amounted to much beyond the spinning of wheels and the occupation of my free time. So over the Memorial Day holiday I decided to force myself to complete one game before the weekend was over. I would conceive the simplest possible game mechanic and UI. I would not worry if it was unoriginal. I would resist the urge to add complexity. I would not get bogged down standing up a framework. I would not build an "engine." I would not worry about clean code, or maintainability, or even performance. I would use the tech stack that I could work fastest in: web tech. And I would not worry that the astral projection of Jonathan Blow would visit me at night and chide me for having made a badly performing web browser game. So, Lorblets is the result. Whatever one might say about it, it IS a game, and that's something. Feedback is welcome of course - but I mostly just wanted to share my story with y'all. June 4, 2022 at 09:13PM

Show HN: Cryptid Zero Trust Authentication and Authorization, Open Source Oberon Oberon makes it possible for a service provider to issue capability tokens to clients in such a way that the service provider never sees the value of the capability token. This prevents the service provider from being able to impersonate the client. Oberon relies upon zero-knowledge proof presentation of the capability token so that the token is never transmitted norrevealed. Instead of the client sending the token to the service—as is done with API tokens today—the client sends a zero-knowledge proof proving that they have a valid capability token issued by the service provider; this is called proof-of-knowledge.

Show HN: A color palette design tool for websites Hi HN, while building something entirely, I realized that there is a lack of tools to pick colors for websites and web apps. While there certainly is an abundance of tools for color palettes, but they mostly give you three to five bright or pastel colors. Not what you need for websites. For that, you need one or two primary colors, and then stuff like text color, background, and so on. So, together with another web dev I built a small web tool that allows picking exactly the colors you need for web projects and live preview your palette on a selection of demo websites. The first version of the tool is online at https://ift.tt/lVIBdhE. Free and no sign up. We are already using this to for early stage projects, so I hope this provides value for you as well. Of course we are also happy about any and all feedback. Cheerz :) June 1, 2022 at 11:38PM
Show HN: Resumecreator.io – I built a simple resume builder Hi HN! I'm a developer who noticed that I haven't done much experimentation lately. I decided I wanted to change that this year. This month I built a simple resume builder with the main goal of practicing front-end development, and to scratch an itch I had when updating my resume. :) After it was functional enough, I casually shared with some friends to express my enjoyment of crafting something just for the sake of having some fun. To my surprise they ended up asking how they could send to others. So I went one step further, due to my pure excitement, and hosted it on Netlify to make publicly available. In case you're curious, I used the React component library Mantine[1] in this project. I loved it, so I definitely recommend to check it out for your next React project. Have thoughts to share? I would love to know! :) If you're postponing starting that project you have been thinking of, just do it. Right now. Just create a new dir, load up your framework of choice and start it, even a couple of lines are enough to get you started. We should never forget that to play around is awesome. -- [1] https://mantine.dev https://ift.tt/C7D8hJS May 31, 2022 at 03:20AM

Show HN: NetBird – A P2P Network with WebRTC, WireGuard, SSO, and Zero Trust Hey folks! We have just released NetBird. It is a big update so I decided to share it here and get your feedback :) NetBird creates an overlay peer-to-peer network connecting machines automatically regardless of their location (home, office, data center, container, cloud, or edge environments) unifying virtual private network management experience. It uses ICE protocol (WebRTC) to negotiate p2p connections and WireGuard (kernel module, when possible) to create a fast and encrypted tunnel between machines, falling back to relay (TURN) in case a p2p connection isn't possible. Pretty much just a client application installation is needed, the rest is done by the software! Sharing the project with you wasn't the only purpose of the post. I wanted to discuss the future and vision behind it. I'm pretty sure that in a few years, such seamless connectivity without the hassle of configuring firewalls, managing IPs, manual key rotations, centralized gateways, etc. will become a commodity and the majority won't be talking about traditional VPNs. But what we think is becoming more relevant is advanced network security. We've seen the rise of Zero Trust with its ZTNA solutions in the past years. There are big vendors like ZScaler or Palo Alto already offering advanced network security features that leverage ML or contextual access controls to allow/block access based on context, not just identity. Why can't this be open-source and built on top of universal connectivity that works anywhere? That is what we are setting as a mission for our project - to bring seamless connectivity and advanced network security together in a single open-source solution. What do you think about it? We welcome contributors and if your excited of what we are building, feel free to reach out to us! P.S. We've been previously know as Wiretrustee :) https://ift.tt/gJV0kpR May 30, 2022 at 12:18AM

The first one being TaskTXT ( https://www.tasktxt.com ), a plaintext notepad with built-in timers. It's full of UI details that were a joy to build with Imba. Trying to build things like this with React in the past honestly made me feel dumb. Imba ( https://www.imba.io ) is a language that compiles to Javascript, like TypeScript or JSX. Imba's syntax diverges much more from Javascript, looking more like Python or Ruby. It's compatible with Javascript and Typescript and NPM modules. It also has fantastic VSCode tooling and even supports TypeScript types. I like Imba syntax better than JS, but the real selling point is the built-in features for building web UI. Imba has first-class support for html tags, css styles, and custom web components. Those are all parts of the language. For me, Imba has replaced Javascript, HTML, CSS and React. Imba's "Memoized DOM" model for updating the UI is an order of magnitude faster than virtual DOM approaches. This allows for simple state management, because you can pretty much re-render the whole UI whenever you want and Imba manages to do that very efficiently. There's an older article about this here ( https://ift.tt/FEKd6ux... ) if you want to dig into the technical details. People often ask for examples of things made with Imba, and the most prominent one is the learn-to-code site, Scrimba.com and its interactive editor. Scrimba was was built by Sindre (creator of Imba) and the Scrimba team. The fact that Scrimba's editor was made with Imba grabbed my attention when I first learned about the language. It's one of the most impressive web applications I've ever seen. Sindre originally built Scrimba to share Imba, but until now there's not been a real Imba course on Scrimba! So, I'm pleased to be fixing that today. I know Imba looks strange to a lot of people. Imba programmers are used to people looking at it and declaring it to be stupid and wrong. An open mind is required. Imba doesn't have to be for everyone, but for a certain type of developer who values design, and wants to build expressive UI quickly, it's pure magic. https://ift.tt/6AOz47g May 24, 2022 at 08:51PM
Show HN: WaifuXL - SOTA image upscaling neural network that runs in the browser WaifuXL is our state of the art super resolution model trained on ~1,200,000 anime style images from the Danbooru2021 dataset. You can run it straight from your browser, entirely client-side, at https://waifuxl.com . Using the Onnx Runtime, we stream the weights of our ML models directly onto your device to be executed locally in WebAssembly. Doing so allows us to provide this service solely through a static webpage, no backend for model execution needed. This has the added benefit of enabling the privacy of your images--your images are not, and never will be, sent to us. Our original inspiration for this project was waifu2x ( http://waifu2x.udp.jp ). In general, our model will outperform those used on waifu2x by a significant margin, without the need for multiple models trained on various noise reduction levels. Note that while you _can_ upscale natural (real) images, the model was only trained on anime style drawings, so don’t expect good results. It does work quite well on non-anime graphic art, however. For more information, see our blog post at https://ift.tt/qxRIT1G https://waifuxl.com May 24, 2022 at 11:46PM

Show HN: Open-source tool to deploy infrastructure in any cloud We have been working on multy.dev, an open-source cloud agnostic API that makes it easy to deploy the same infrastructure to any cloud provider using native managed services. The motivation was the realisation that, even when using Terraform, migrating infrastructure code requires an end-to-end re-write. Even though most core resources are the same in any major cloud, developers need to learn a new provider to deploy the same infrastructure when moving providers. We are still in early days of development and currently support the core services from AWS and Azure: - Networking (virtual_network, subnet, route_table, security_group, network_interface, public_ip) - Compute (virtual_machine, managed kubernetes) - Database (managed MySQL databases) - Vault (managed secrets) - Storage (managed storage) - Abstraction of cloud differences (Azure VM public vs AWS EC2 private by default) - Deployment through Terraform We’re looking for feedback from other developers about our approach. Let us know your thoughts! GitHub: https://ift.tt/xIdgWSj https://multy.dev May 16, 2022 at 11:05PM
Show HN: KittenDNS – easy to setup, rule engine, LetsEncrypt compatible My goal was to create a DNS server as simple as the LDAP server I've been contributing to (glauth) and here it is: https://ift.tt/i6S4IHQ A few things to know about it: - It is easy to configure using a Toml file - I am using it to bail my coredns/etcd instances when under attack - (yes, it also works as a service location server) - It comes with a simple, plain English, rule engine that doesn't do much at this point - It can be used with LetsEncrypt. I use it to retrieve certificates for my home servers. - RFC: all the nice ones :) Anyway, feedback is welcome. May 16, 2022 at 03:04AM
Show HN: Babeloop, a new music sight-reading webapp Backstory: I have a kid learning to play the clarinet in a music conservatory, which involves compulsory sight reading classes. Teaching for sight reading is done on books. The idea for this app is to port the method online, so that it's easier to practice and follow one's progress. It should also be more fun, and, for those so inclined, competitive. The learning method is based on landmarks: for each clef one first learns the position of 2-3 landmarks, and then each note is in relation to a landmark. So for example, if you know where the middle G is on the treble clef, then you can learn fast that 2 positions up (next line) is B, and two positions down is E. (Anecdotally, in an earlier iteration of the app, landmark notes were displayed using specific colors; but users learned colors instead of the note position on the staff, and when they moved to a level without colors (or an actual score) they were completely lost.) The app doesn't try to teach keyboard playing, or fingering for any other instrument for that matter. It only helps associate the position of a note on the staff with a name, in a given clef. It doesn't deal with octaves: a C3 is a C4 is a C; or accidentals: a sharp G is a flat G is a G. It also doesn't wait for user input, as other apps do. Music doesn't work that way; but more importantly, the point is to learn to recognize intervals instantly, not count them. No account is necessary to use the app, only to participate in the leaderboard, and save one's score in case of device reset (or to use more than one device). When an account is created, the data is stored on the server in SQLite; I'm curious to see how far it can go. (Without an account, no data leaves the device.) It's still a little rough around the edges but should work ok in reasonably recent browsers. On the client side, it uses VexFlow to display notes, staff and clefs, but animations are done using CSS transitions (not JS), to be mobile friendly. Tone.js helps provide a more accurate timing than a simple setInterval. Icons are coded in SVG by hand; for simple shapes, this is surprisingly fun and straightforward to do. https://ift.tt/jXSIi5Q May 15, 2022 at 10:25PM

Show HN: A collaborative pixel drawing game for when you're bored (Attempt #2) Previous thread: https://ift.tt/OJmXEgt Hello again HN! It's been 3 months since I last submitted this project and the back-end server software melted down. I was really bummed that many people didn't get to play, so I've spent most of my spare time since that last post completely rewriting the back-end server software using small, carefully selected dependencies (C99, sqlite, mongoose.ws & cJSON) I've done some basic performance testing and I'm cautiously optimistic that it can now handle up to ~1000 concurrent users. If you have any ideas for improvements, do let me know! Bots are permitted, but try and do something creative instead of just filling the canvas with junk :^) You can view the source code for the new back-end here: https://ift.tt/LZIvSa4 You can also check out a recent time-lapse here: https://www.youtube.com/watch?v=FUmnUvTqn6M The time-lapse gets generated from the server log output using this tool: https://ift.tt/8odZ13H (Note to HN staff: It wouldn't let me repost this unless it had a 'slightly different url', hence the sneaky redirect there.

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. I created a short video to show you how to create a minimal Hacker News clone with Bud: https://www.youtube.com/watch?v=LoypcRqn-xA . The framework is free, open source and MIT Licensed. You can find it on Github: https://ift.tt/m8a1ILk . 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. At this point, I just had the following goal: • Be as productive as Laravel in a typed language like Go. 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. With these newly discovered constraints, I started working on the next iteration. Bud should: • 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. • 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. With these new goals, the Bud you see today started to take shape. But along the way, I discovered a few more project goals: • 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. • Bud should be able to provide high-level APIs for developers while compiling down to performant low-level Go code for production. • 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. It's still super early days. You can find the the Roadmap on Github: https://ift.tt/7GeNiln . I encourage you to contribute your thoughts. And here's the current documentation for what's already in Bud: https://ift.tt/Ggx9wIM... . Comments are enabled for anyone to chime in. I have big plans for the framework. I hope you'll join me on this journey to build ambitious websites faster with Go! https://ift.tt/m8a1ILk May 14, 2022 at 12:31AM
Show HN: Catchy melodies made with a diffusion-based neural net assistant I've created a diffusion-based neural net generative assistant that makes creating new melodies much easier, even for non-musicians like me. These are meant to be just the catchy "hook" parts of songs, so more work is required to make them into full songs, but this is already handled well by existing products (e.g. there are plugins that can suggest a few possible chord progressions based on the melody and there is even good singing software that I used without any tweaks to make the “voice” playlist: Synthesizer V Studio). This side project turned out to be quite challenging because of how little data there is to train on - several orders of magnitude less than DALL-E or GPT-3 had available for its training, so it required a deep dive into research of new generalization and augmentation techniques and some feature engineering.

Show HN: Wordle in Python using literate programming Hey HN! I wanted to demo TDD with Python, as well as showcase some BDD practices I've been blogging about recently[1]. So I used literate programming to implement Wordle, and rendered the narrative into this "Show HN" webpage. I'm certainly no Knuth, but I'm pretty proud of the result. Proud enough to chance myself to a HN post, and risk HN's mockery and ire: my first "Show HN". I hope this crowd will enjoy this annotated walkthrough of Wordle implementation in Python. Codebase available on Github[2].

Show HN: Jira to Gitlab Issue Migration Tool $DAYJOB needed to migrate from JIRA to Gitlab due to business reasons (not related to the recent outage), so I wrote this issue migration tool [1] to help us preserve our historical data. This tool will copy issues from various JIRA projects to mirrored Gitlab projects (e.g. A jira project named JIRA-PROJECT1 will have its issues migrated to a gitlab project GL-PROJECT1). The tool also migrates issue comments to Gitlab notes and will recreate the existing issue links. YMMV, but this is working well for us.

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. I'd love to get your feedback :) https://ift.tt/I36EAbO May 8, 2022 at 01:18AM
Show HN: I made Ankify that converts notes to Anki cards Backstory: I was in medical school and had to study a ton of materials in short period of time. I came across Anki but always had trouble with making cards. In my mind, making cards should be quick, seconds instead of minutes. My other problem is after making the cards, each card does not really relate to the other. When you study the individual card, your thought process is very random and not cohesive. I wanted to be able to still reference to my notes for big concepts and then use the cards to memorize the details but also for long term retention. Ankify came out of that. At the time, I did not know any programming and paid someone to write a script in Python to convert the cards. Then, eventually I learned Python myself and expanded on the script. I also uploaded the markdown files online so I could view them anywhere ( https://ift.tt/4e2AFHK ). I ran into a wall in making user interface for the program. It was difficult to make good looking cross platform user interface with Python. I gave up on making user interface for a year or two with end of med school and residency. After a while, I went back to see if anyone else had made anything similar. Despite many plugins/programs that makes it easy to make cards, none of them really focused on readability of the original notes. I decided to sit down and learn javascript to help with UI creation. After about 3 years, everything finally came together after I learned Svelte, Tailwind, and Electron. I know Electron is not the most efficient program, but it's what works for me. Also, it's also the feeling of being able to make whatever my mind can think of. It feels really refreshing and empowering. Even making the website for Ankify is a lot of fun. You have to think so much about the presentation, typography, logistics. https://ift.tt/QGjZwKY May 7, 2022 at 07:03PM

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.

Show HN: Kontxt – Social web layer with CMS and social network Hey, I’m Dave, the founder of Kontxt.io ( https://www.kontxt.io ). Engage directly on the web and save, organize, and share highlights and notes. Follow people. Join groups. And search content. Here’s a 2-minute demo ( https://youtu.be/Th4vaOzuGnU ). It works on desktop and mobile. The web layer is like Google-Doc collaboration on the entire web, and it’s connected to a web app that’s like a combo of DropBox to save and organize your findings, and Twitter/Reddit to share and discover bite-sized article highlights with other people. 1.) The Social Web Layer has rich collaboration features with privacy and share controls: Inline highlights, tags, polls, comments, @mentions, deep-links to anything you add to the page, and navigation between parts. The web layer can be added to any site or PDF with a single line of javascript. This is done with a browser extension, bookmarklet, or added to a page directly by the site owner with the word-press plugin or hard-coded javascript. 2.) The CMS and Social Network lets you organize with folders that have privacy and share controls, a profile with your public highlights, a feed of highlights from people you follow, groups with feeds around topics, and the ability to search your content and what others share publicly. For years, I had a long commute, so I read online a lot–from HN, of course. There’s too much to read everything, and you only know if an article is “worth-it” after you read it. Then it hit me. Highlights! 1.) On the page with navigation, 2.) visible before you open the link, and 3.) to increase quality and relevance, follow and search highlights by trusted people like friends, co-workers, university peers, and industry leaders. There’s too much information and not enough time. Highlights are short, useful, and fast to read. Kontxt.io lets you direct attention to what matters. First, it lets you find quality sources from trusted people, then it lets you focus on the important parts of them. Kontxt basically turns the web into an interactive workspace so you can have rich web interactions with other Kontxt users. Or you can extract highlights into a shareable link and post it anywhere on the web–with analytics for what you share. Highlights are automatically saved to the CMS and based on their privacy settings, may be published to feeds in the social network for others to see. Naturally, you may want to discuss the same site with different people for disparate reasons, so you can create multiple highlight layers on a single site, each with Google-Doc-like sharing, privacy, and authorization controls. It’s now evolved into a general communication and engagement platform for the web. Here’s how Kontxt has been used or where people expressed interest: social news aggregator, productivity, research & planning (generally, and specifically for sales, law, & finance), knowledge-base, training & education, publisher inline-engagement system, etc. Kontxt gets to the point fast. It brings collaboration directly to the web itself and is already part of your natural workflow since it's always with you every click of the way. The social network is unique since it uses highlights to seed discussions. This has many benefits. Highlights mean people have actually read the article, the source is cited, and parts can’t be misconstrued because you have context. It’s also a human filter of the internet. A site is likely worthwhile if someone took the time to highlight it, and if someone found it useful, then someone “like” them probably will, too. Similarly, if someone’s not willing to highlight a site before they send it to you, it’s probably not worth your time. And highlights will increase how many people actually read what you send them because they’re short, useful, and fast to read. I’m excited to share this with all of you. Thanks for your time. Please leave any feedback or questions in the comments. If you try it out, be sure to join the “Hacker News” group. https://www.kontxt.io May 2, 2022 at 11:45PM

Show HN: WeakVim, My attempt at a modular, transparent starter kit for Neovim Hi all, I _love_ Neovim. However, I think many parts of it could be easier to configure or understand, especially when it comes to LSPs. There's a ton of plugins that fill the gap, but some of them are sparse in documentation. There's also distributions like LunarVim that attempt to add a Doom Emacs-like layer above. My approach is a bit different, simply giving an opinionated, modular, and documented configuration that an interested user can easily modify to their needs. It makes use of the most helpful plugins I've encountered to create the best experience I could muster while retaining an air of simplicity. I hope this is helpful to someone out there! https://ift.tt/ykR8OzY April 29, 2022 at 05:33AM
Show HN: Lists.sh – A Microblog for Lists Greetings, creator here! I've been working on a new blogging platform specifically for lists on and off for a few months now and I'm excited to officially announce its launch. After seeing https://charm.sh a few months ago, I've been enamored by the idea of SSH apps. I decided that a blogging platform focused on developers could be the perfect use case for an SSH app. Also, I love writing lists. I think restricting writing to a set of lists can really help improve clarity in thought. The goal of this blogging platform is to make it simple to use the tools you love to write and publish lists. There is no installation, signup is as easy as SSH'ing into our CMS, and publishing content is as easy as copying files to our server. Check it out and let me know what you think! source: https://ift.tt/gdVMGUv https://lists.sh April 25, 2022 at 07:14PM
