Show HN: Brew.fm – Let bots discover new music on Spotify for you Use Spotify? This tool will automate your music discovery for you. Join here (100% perpetually free with no strings attached): https://brew.fm Some time ago, I built and showed HN[1] brew.fm, a tool helping artists remix each other’s work. It had been quiet, and I remembered how fun it was to work with the Spotify API, so I repurposed the tool to solve one of my own problems: missing out on new music of my favorite artists. I shared it on Reddit yesterday[2], and this seems to hit a spot for more people: so far 833 people connected their Spotify account. How it works: The tool simply shows your top 50 artists on Spotify over short, medium and long term, and checks those artists for new music. If you select a playlist, every artist involved in the tracks will be checked for new music, after which new releases are shown sorted by most recent release date. Here’s a video of me demoing the tool: https://youtu.be/Nh2Ognb4PgU . Enjoy! Very open to feedback.

Show HN: Pi-hole deployed at the edge on Fly.io and accessed via TailScale Hi, I just saw this tweet[^1] by @QuinnyPig that mentions accessing your Pi-hole while traveling thanks to TailScale and wondered how to deploy Pi-hole at the edge, instead of a home lab, for improved latency. My simple solution involves running it on Fly.io to make it easy to relocate anywhere, and embedding tailscale into the same firecracker VM (né docker container) to keep the infra dead simple and cheap. Naively deploying a publicly accessible DNS resolver is not ideal[^2] so the main constraint was to secure the VM by 1) keeping all public ports closed and 2) having Pi-hole listen only on the private network interface created by TailScale. It's all very straightforward but it's noticeably improved my bandwidth usage and page loading times across my laptop and mobile phone, so I figured I'd share. Suggestions for improvement are also welcome! [^1]: https://twitter.com/QuinnyPig/status/1558521941538983936 [^2]: https://ift.tt/Fj4H3kK... https://ift.tt/ERNu6j9 August 18, 2022 at 11:03PM
Show HN: We built an AirTag-like network for sensors that talk to your servers Hi, we’re Simon, Don and Dan, and we’re developing infrastructure for enabling Bluetooth devices that can communicate with your web backend (we’re calling it Blecon). Think your own AirTags network, but for sensors talking to your servers. We’ve got most of the underlying tech for the network infrastructure in place, and now have samples of a first manufacturer device that supports Blecon - a small rechargeable accelerometer tag. Not much live yet, but we put a summary of this first device and how it works in the link (plus you’ll find some early developer docs for the network infrastructure itself). TL;DR the tag logs timestamped motion and orientation events, and then sends the data using Blecon when phones come nearby. The data arrives at your specified network endpoint as JSON HTTP POSTs, so it is nice and flexible for integrating into any web infrastructure or framework you might be using. The customer use case for this device is actually monitoring when and how long equipment is being used, but motion and orientation can be used to infer a lot of things. Interested in what ideas you have for services you could build with just this first accelerometer sensor?! We’re still developing the network product, but interested in feedback, ideas, questions and use-cases. And if you are really interested we do have samples of this sensor so feel free to reach out if you have a service you’d like to try building with it! https://ift.tt/O3RvVCb August 18, 2022 at 11:29PM

Show HN: I made a tool to build badges in Pharo I'd like to share with you a new app for building badges made with Pharo 10 (a fork of Squeak Smalltalk). It is based on the Shields.io badge generation provider. The idea is to select the badges you want, complete the required variables, and get your badge(s). You can also save and load commonly used variables, so it may help a bit to automate presenting your project's README. Hernán https://ift.tt/SmfnMAV August 17, 2022 at 11:13PM
Show HN: Crabs All the Way Down – Running Rust on Logic Gates Made an ARM Thumb CPU from scratch in a digital circuit simulator for fun and decided to push the joke a little further and run real stuff on it, like a Web server, a Scheme interpreter, a MIDI player, and a VT100 emulator.

Show HN: Hire experts in popular SaaS/no-code tools Hi HN We have built Heep to help startups take advantage of the best no-code/SaaS tools and increase their ROI on the tools they already are paying for. It's super simple - we match you with experts in popular tools like Notion, Bubble, Webflow for any kinds of project. So far we had over 200 companies build all kind of staff with makers on Heep - from improving their internal ops with automations (Zapier, Airtable) to building full scale MVPs (Bubble, Glide). We focus on curating talent and making it easy for anyone to navigate the no-code space. We have messenger and payments built-in inside the platform and adding simple contracts soon. On the talent side we are allowing you to monetise your expertise in any SaaS/no-code tool and earn $2K+ per month. Right now we have over 300 experts on the platform across 40+ tools. We are still working on making the experience smooth for customers and the main point of launching here is to get feedback on what could be done better on finding/hiring an expert. Would love to discuss what do you like/dislike about existing freelance platforms out there. Love from Kyiv/Berlin https://heep.so/ August 16, 2022 at 11:52PM
Show HN: Learn words in a foreign language by typing I’m Brazilian and I made this tool for my brother to learn English. He’s also trying to learn the keyboard layout at the same time. So far he seems to be liking it and getting better. I manually built and open-sourced the dictionary on github, so anyone can contribute and add more languages. I’m doing that manually because I want to do that in the most easy and didactic way possible, with a very accurate translation and most used words. Ideally, in the next version, it will be using some sort of API or automated tool. I’m not sure how to make the dictionary work effectively because each description needs a very close translation (ideally as exact as possible). We’re not able to just copy words and descriptions because they won’t necessarily line up with the other language translations. We’re currently manually translating to be accurate, though ideally we can figure out a good way to scale this, if anyone has suggestions please let me know! https://ift.tt/1AslLvF August 16, 2022 at 11:16PM
Show HN: I made a tool to hide HN usernames and reduce bias Hey HN, I made this tool after I read a pretty interesting pg essay - https://ift.tt/5Vlz9A4 He talks about changing some HN usernames' colors to orange and then deciding to revert back So I thought it could be interesting to remove usernames entirely. This Chrome Extension just replaces HN usernames with question marks. I've enjoyed using it so far myself and I'm curious what you think about the concept? https://ift.tt/5KbhRoD August 16, 2022 at 01:25AM
Show HN: XaaS Pricing – track 25k+ SaaS company pricing strategies in one place Hi all - I'm completely new here! I come from a market analyst background - I've done large B2B tech pricing research and consulting projects for over 10 years. I wanted to figure out a way to scale what we do in those projects to a broader set of SaaS companies that can't pay the six-figure plus price points those projects often carry. Today is our first step on figuring that out - we've created XaaS Pricing, a tool that let's you analyze the pricing strategies of 25,000 SaaS vendors across 50+ metrics, on-demand, with real-time updates when pricing strategies change. I hope it's helpful and look forward to feedback and questions from the HN community! https://ift.tt/yaGEw5R August 16, 2022 at 01:01AM
Show HN: OxideDB – Teach PostgreSQL Database How to Speak MongoDB Wire Protocol Hey everyone! I have created a product that relies on MongoDB for a document store but doesn't really need any of the distributed features to really justify having a hosted MongoDB or DocumentDB instance. Now that we're trying to turn this into a product, we're seeing that some companies have a little bit of resistance around managing yet another database. Most of our clients already have and manage PostgreSQL in one form or another. I knew that PostgreSQL already offered first class JSON support, but I didn't want to rewrite the application data layer from scratch if I could avoid it. That's when I started researching if there was a "proxy" that would translate the MongoDB protocol - that I was completely ignorant about - into PostgreSQL. To my surprise there was nothing ready for production use but I found MangoDB that later on became FerretDB. I delved into the code and was in love with the idea. The team around is really nice, but I found that they had greater ambitions - they basically wanted to offer multiple backends, namely Tigris, on top of PostgreSQL. On the other hand, I have been waiting to find an excuse to delve deeply into the rust ecosystem but never really found something I was passionate about until I had the idea of challenging myself to see if I could learn about the protocol that MongoDB uses by relying on their public documentation and the hints I found on FerretDB. Fast forward 3 weeks and I have something I am almost comfortable on sharing yet super excited to get feedback on. It's in very early stages, and it's work from someone that is not yet super comfortable with the stack. Please don't be too harsh and keep in mind this is the beginning of a journey for me that I embarked out of pure joy on getting a tiny bit better on rust and making things click internally. Thank you for your time and if you would like to help me on this project please be more than welcome to reach out, either here, via email or directly on the GitHub repo. (heavy breathing before clicking submit :-) ) PS: I forgot to mention, but another thing I added to my toolbelt while developing this was about creating parsers. In order to transform MongoDB JSON to SQL queries, I ported an existing library from the MongoDB team from PEG.js to pest.rs! https://ift.tt/R74Uq9I August 15, 2022 at 10:43PM
Show HN: Anysphere, home for important, long-form conversations Hi everyone! I’m Arvid, cofounder of Anysphere ( https://anysphere.co ). With my two friends Sualeh and Shengtong I have been spending the last few months building a dedicated home for important, long-form conversations. We’re super excited to let the HN community test it out! We think that no existing platform for point–to-point communication prioritizes the conversations that you actually care about and that really matter. Instant messaging is filled with careless texts and stickers, email is filled with receipts and spammers, and physical mail, while better in those respects, is slow and cumbersome. None of the existing platforms are private enough. Anysphere attempts to fix this. It is private, secure, desktop-first and only allows people you added to contact you. Our whitepaper ( https://ift.tt/6v9KubI ) describes our privacy and security model in detail — in short, we protect all of your data and metadata against everyone (even our own server). Our client is fully open source: https://ift.tt/5HgsBhD . We deployed a small server to open up testing to everyone in the HN community. Instructions are here: https://ift.tt/v6qSQXM... . I can’t wait to hear your thoughts! https://ift.tt/EL6yP8Q August 15, 2022 at 06:17AM

Show HN: Bog Gobbler Word Game Two years ago my pandemic project was an online multi-player variant of Scrabble named Crossword Island Hopper where you capture territory by placing words on a board. It proved to be wildly unpopular. More recently I have been working on Bog Gobbler, which is a variant of Boggle where you capture territory by finding words in the grid. The territory-capture element is much more relevant in the multi-player game, but also affects the mechanics of solo games. This one is a little more popular and there is a daily solo challenge where everyone plays the same grid, with a global and personal leaderboard. You can go directly to the daily challenge at: https://ift.tt/t6FQYo8 If you know how to play Boggle the one thing you need to be aware of is that after the first word you find, all subsequent words must include at least one letter that you already "own". https://ift.tt/C6RDivX August 13, 2022 at 10:41PM
Show HN: Wordle but for Tweets Hey HN I built this simple app that grabs four popular tweets from the last 24 hours and removes a word from each, so that the missing words spell out a phrase. It's the player's job to guess the missing words. A key motive for building this was that, to be honest, I was finding much of the news and social media dialogue quite depressing. I thought that if a wholesome or inspirational phrase can be built out of these (often tiresome) tweets, then there would be something nice about that. The stack included GCloud scheduler (for daily Tweet scraping and automatic puzzle generation), Supabase (which, by the way, is fantastic) and Next / Vercel. https://www.birdle.art/ August 12, 2022 at 02:04AM
Show HN: Releese – Music business management software After working in the music industry myself as an artist (Midsplit) and as a label manager / employee (ChillYourMind, Strange Fruits) I noticed that the music industry has very antiquated tools that are often expensive and rarely updated. I had the idea to build a platform that could streamline the entire releasing process of music, we nailed it down to metadata management, royalty splits, landing pages generation, distribution to major stores and royalty collection (publishing + neighboring) rights. After building this with a small team for 18 months, we finally managed to create our vision with a surprisingly functional product. Our cloud infrastructure is based on Google Cloud and our app is 98% Typescript (Thank you Github) I would love to know how someone in or outside the music industry feels about the platform. Hopefully we will help shape a better music industry! https://ift.tt/LZT2EfC August 11, 2022 at 01:47AM
Show HN: MOS, an application to help you deploy mathematical optimization models We built MOS in response to the frictions we experienced in deploying optimization solutions. Some of the key benefits provided are the following: - Models can be easily uploaded to the application after adding simple annotations to the model code. - Models can be accessed via various available interfaces, including a REST API, a web graphical user interface, and client libraries in popular programming languages such as Python and Julia. - Models can be run with different inputs by workers running locally or distributed over the network. - Intermediate and end results can be extracted, browsed, and analyzed. This is all available without the need for (the typically required) custom ad-hoc code. https://ift.tt/tkndB4q August 9, 2022 at 11:28PM

Show HN: Apprise v1.0.0 – A lightweight all-in-one notification solution I introduced Hacker News to Apprise back when it was just an experiment (and supported just 30 or so notification services at the time). Now supporting more then 85+ services and with a ton of built in features, I officially created it's first stable v1.0.0 release marking a major milestone for the project. Apprise doesn't compete with other notification services out there; instead it just acts as a proxy (or master switchboard) to support handling messages to them. It's a means of decoupling notification support from the systems that want to provide them. The idea is to adopt Apprise into your environment, and then you no longer have to worry about adding/removing support for new services as the come along and deprecating the ones that go away. The way it works is that every service out there maps to a `schema://credentials/?optional_configuration`. You just need to define the schemas you use, and then you can already use Apprise. Check out the list of the services available today here: https://ift.tt/QGFk1L3 Apprise is 100% open source (MIT Licensed). It has an acompanied API I built for those who want to centralize their configuration (found here: https://ift.tt/Wr7oUnS ). Some reasons you may also all find it useful: - It works perfectly with legacy servers (supporting even Python 2.7). So this fits system admins using older systems such as CentOS 6+ - It has a complete API that developers, devops, and administrators alike can leverage allowing them to control the notifications in their environments. - It supports configuration files allowing you to securely hide your credentials and map them to simple tags like `family`, `devops`, `marketing`, etc. There is no limit to the number of tag assignments. It supports a simple TEXT (https://ift.tt/D7qrx1n) based configuration, as well as a more advanced and configurable YAML (https://ift.tt/JQqs1g0) based one. - It sends all notifications asynchronously optimizing setups where there are many end-points to deliver to. - It supports inputs are of MARKDOWN, HTML, and TEXT and can easily convert between these depending on the endpoint. For example: HTML provided input would be converted to TEXT before passing it along as a text message. However the same HTML content provided would not be converted if the endpoint accepted it as such (such as Telegram, or Email). - It supports breaking large messages into smaller ones to fit the upstream service. Hence a text message (160 characters) or a Tweet (280 characters) would be constructed for you if the notification you sent was larger. - It supports file attachments too. So feel free to pass along an image, PDF, etc if the destination supports it. - It can easily allow you to write your own custom notifications and/or simply leverage Apprise as routing service to perform admin tasks for you. See here for more details: https://ift.tt/jI4cUlM - It has 100% code based test coverage. :) I hope to continue to add more services (and break 100+ supported services someday). I also hope some of you find it useful for your own project solution! https://ift.tt/pCa3eo4 August 7, 2022 at 10:21PM

Show HN: A Gauss-Seidel solver visualization in a single HTML file Recently I was reading about fluid simulation and stumbled upon the Gauss Seidel method. I got interested in how it works and made a program that visualizes the method in action. I had the idea of making an interactive book-like thing for a while, so took this as a chance to do just that. Note that touch input doesn't work and the layout is targeted towards bigger screens, so it doesn't function properly on mobile. It was fun to make and I wanted to share it. Maybe someone will find it useful. Corrections and feedback are welcome. Technical Stuff - A single 1.7MB HTML file with embedded JavaScript and WebAssembly.

Show HN: A link/news aggregator I am working on Hello HN, I'm building omegapedia.com, a link/news aggregator that combines features of multiple other sites. I started building this site because I often found some features lacking in other websites. As example: You can format you text to be italic, red, blue or to be a spoiler. Comments are not threaded and don't include any voting feature. Omegapedia uses upvotes and downvotes for posts but shows them as separate numbers. I styled the page in darkmode but added an optional lightmode as well. I added "Trust-Points" and a leaderboard to show the 5 users with the most points. Other noteworthy features are: -Comment replies. -Flairs. -Adding a bio to your profile. -Mention users in comments. -Ability to add a email address to your account. -Forgot-my-password function. -Link posts. There is no need to add a email andress to your account and you will never be forced to. The site works on pc and mobile. The site is very lightweight because there are no CSS or JavaScript libaries that will have to be downloaded first. There are multiple ways to sort the posts and a way to show the recent comments so you can join a current discussion anytime. There is no register barrier and you will be automatically logged in a muted guest account. I am very interested in feedback and if you have any questions or comments please let me know, thank you! ======== Join me on omegapedia! https://ift.tt/FZcmAV5 https://ift.tt/ixzgcrF August 5, 2022 at 10:25PM

Show HN: Penumbra, a perceptually optimized color palette based on natural light For this palette, I used recent advances in color science, which made perceptual design more accessible, to choose a set of colors (mainly for syntax highlighting) that have uniform luminance for less visually uneven, fluidly readable code, but at the same time maximally distinguishable hue and chroma. The background colors are based on natural (sun-)light and shade for a more pleasing look than equally neutral greys. For much more detailed info, including the construction, check out the repository. There’s also already a (bare-bones) VSCode extension, linked in the repository, but it could admittedly use more informed distribution of colors over tokens, language specific highlighting and perhaps more opinionated use in UI elements. https://ift.tt/ghVoCe6 August 5, 2022 at 02:53AM
Show HN: Butt Mover - A butt triggered productivity and health improvement game Productivity timers needed to be triggered manually before each task, Making it a chore by itself, Often leading to us not using them after a while and They don't take health into consideration. Health timers are intrusive, Even then they are not always accurate and They don't take productivity into consideration. Butt Mover addresses those problems by using a butt trigger for automatically starting the productivity timer when we sit on the chair before our workstation and a break timer which reminds us to take a walk automatically when we get up. Butt Mover also incentivizes its usage through a Game. When the health(tasks/breaks) reaches zero its game over. I've been iterating different forms of Butt Mover over past two years and released the web application earlier this year(After feedback from several HN users). Today I'm making the core application open-source as I've committed myself to make the Health & Education applications I build open-source. I hope you'd use Butt Mover for yourself and build Butt Trigger for others to improve productivity and health. Feedback and contributions to improve the project is appreciated. https://ift.tt/pugkDzr August 5, 2022 at 12:25AM

Show HN: MutableAI (YC W22) – Copilot Alternative for VS Code Hi HN, We’re MutableAI (YC W22) ( https://mutable.ai ). Our mission is to reduce the time and cost to create high quality code using AI. We have worked at the full gamut of companies ranging from startups to big tech and have gotten the sense that many of the rote aspects of software development could be made easier, freeing up precious mental energy. Devs love Copilot, but autocomplete is just one of many ways that AI should make programming easier. We’re taking a more comprehensive approach to developer tooling that bundles Copilot-like autocomplete with documentation, custom AI instruction, and some early refactoring capabilities (Python only) in one extension. We currently support Javascript/Typescript, Python, Go, and Rust, with more coming soon. Overview (w/ bg music) [3]. In addition to autocomplete, which can be triggered either automatically or manually, we can add documentation to all your methods in a Rust file, or you can ask the AI to insert missing imports in a Python file. In some cases we can get really sophisticated and ask it to program a game from scratch or update your REST interface to accommodate a new data payload. We use a combination of AI (e.g. OpenAI codex) and AST transformation / metaprogramming techniques on the backend. We are also working on providing other backend solutions for varying needs, including on-prem deployments. We soft launched our product with a small cohort of users and want to welcome more of you to our pilot beta. We hope you enjoy the product and look forward to learning from you. We are currently in an extended free trial phase for early adopters and plan to keep a free tier for solo devs and open source contributors. We also offer a generous discount to startups. For enterprise please reach out to info@mutable.ai We want to thank our very earliest users and invite the HN community to try the product installing it via the VS Code marketplace [1] and email us directly with feedback or feature suggestions (support@mutable.ai).

At the moment we've implemented Google calendar synchronisation, basic tasks and notes. Also Emery has some things we really wanted to see in other apps – private notes for meetings, categories that can be used to group tasks/notes/meetings together, weekly productivity reports. Happy to hear any feedback and answer any questions! https://emery.to/ August 2, 2022 at 03:12AM
Show HN: ProxSNI, a transparent HTTPS tunnel for self-hosters I'm self-hosting my stuff, and pay dearly for a fixed IP from my ISP. Either you do that, or you rent a VPS and set up a somewhat complicated scheme to forward traffic to your home, or maybe you feel like giving Cloudflare access to all your files on the way to you [1]. Maybe that's too much, and you change again to a VPS setup. Well I felt like an option was missing: An SNI-sniffing reverse proxy. That's exactly what ProxSNI [2] is. Using the open-source (!) client, all HTTP and HTTPS traffic is forwarded to you, without breaking any encryption (since SNI was never encrypted in the first place). That means your traffic is always yours, and ProxSNI just forwards it to you. You are in charge of getting a domain and setting up your server at home, we just send you your traffic. Where other mail men in this area will open your letter to make sure nothing bad is inside, we simply read the address on the envelope and deliver it, and put some pride in letting you decide what's best for you. I hope you'll try our service free of charge for the duration of this beta-launch. [1] https://ift.tt/vRh30rt [2] https://proxsni.com https://proxsni.com/?hn August 1, 2022 at 09:09PM
Show HN: Rentaflop – Render your Blender projects without sacrificing quality Hi HN, My name is David Sokol, and I'm the founder of rentaflop (https://rentaflop.com). We're a crowdsourced render farm aimed at making Blender rendering fast and affordable. If you've used Blender, then I'm sure you've experienced the pain of waiting around for your animations to render. You've probably even had to sacrifice the quality of your work to reduce your render times. I've been there too. If you're like me, then you're also disappointed with the alternative solutions: spending thousands of dollars on graphics cards or using prohibitively expensive cloud render farms to get fast render times. Our solution to this dilemma is to leverage low opportunity cost hardware from around the world to allow Blender artists to render their projects quickly, affordably, and without compromising on quality. Since most graphics card owners aren't utilizing their hardware to do valuable work 24/7, we provide them with a way to make money without lifting a finger, while lowering the cost curve for 3D rendering. We're currently doing a private beta. If you'd like to get early access, check out our site (https://rentaflop.com) and join the waitlist. If you're a graphics card owner who wants to help Blender artists while earning money, reach out to support@rentaflop.com and we'll help you get set up. Please leave a comment below, we'd love to hear your thoughts :) August 1, 2022 at 04:29AM
Show HN: Ordinary Puzzles, a free puzzle game inspired by Picross and Sudoku Hello hello HN! I wanted to share with you Ordinary Puzzles, a little puzzle game I designed and developed in my free time, inspired by Picross and Sudoku. I already posted it here ages ago, but I wanted to share it again now that I updated it to also be playable online as a Progressive Web App. Ordinary Puzzles is open source, is built with React Native, and it’s available on the mobile app stores, on the web (as a PWA), and as an Electron app. Hope you give it a try! (Please don’t skip the short tutorial :P) https://ift.tt/dNzyXMH P.S.: The puzzles come from https://ift.tt/pWqgL0b (the author is credited and has been contacted before using them). https://ift.tt/xO79KDp July 31, 2022 at 11:01PM
Show HN: I've been making JavaScript sandbox alone for 6 years Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work. https://playcode.io/ July 31, 2022 at 09:57AM
Show HN: Chunk – Code sandbox for back-end devs Chunk co-founder here. We spent the last 2 weeks building this to scratch our own itch: As developers, we often have problems that could be solved just by running a few lines of code. Sometimes, running this code on your local machine is fine. But other time, the code need to run automatically reacting to external events or to run continuously, which means, it needs to run on a server somewhere. So now, you have to find a cloud provider, to package or build the code and finally to deploy it. All of that for what could be literally be 4 lines of code. We couldn’t find an easier way to do this, so we built it. Chunk is an all in one web editor (think of the codesandbox experience) that allows you to write, deploy and run a piece of code in the cloud from a variety of triggers: HTTP, WebHook, manual or scheduled (cron). No setup, no build, no deploy. Chunk makes you go from idea to code running in the cloud in seconds. Let me know what you guys think! https://chunk.run July 28, 2022 at 11:19PM

Show HN: TapeMeasure – Swift class for creating segmented, labeled lines in UI TapeMeasure is a utility class, written in Swift, for generating a visual tape measure, or any other graphical elements that need layout in a measured sequence. I created this class to help with a pet project I'm working on, where I needed to generate segmented, labeled lines to use as axes on charts and graphs. It occurred to me that this seems to be a pretty common task, involving a lot of boilerplate code and tedious calculations. Why not decouple the code and move it into a dedicated class? It's self-contained, nice and simple, and easy to unit test. It can also handle a lot of tweaks to the "tape measure", such as boundary clipping and shifting offsets. It's especially good for animation, where you can just change a parameter or two during animation, and call for the re-calculated data to re-render your measured line. That makes it great for animated sliding and scaling effects. Anyway, enjoy! https://ift.tt/6LPoFb7 July 29, 2022 at 11:09PM
Show HN: TensorDock Core GPU Cloud – GPU servers from $0.29/hr Hello HN! I’m Jonathan from TensorDock. After 7 months in beta, we’re finally launching Core Cloud, our platform to deploy GPU virtual machines in as little as 45 seconds! https://ift.tt/o7EtsVz Why? Training machine learning workloads at large clouds can be extremely expensive. This left us wondering, “how did cloud ever become more expensive than on-prem?” I’ve seen too many ML startups buy their own hardware. Cheaper dedicated servers with NVIDIA GPUs are not too hard to find, but they lack the functionality and scalability of the big clouds. We thought to ourselves, what if we built a platform that combines the functionality of the large clouds but made it priced somewhere between a dedicated server and the large clouds? That’s exactly what we’ve done. Built to make engineers more productive. We have 3 machine learning images so you can start training ML models in 2 minutes, not 2 hours. We provide a REST API, so you can integrate directly your code with ours. And, there’s a community CLI you can use to manage your servers directly via command line We provide a feature set only large clouds supersede. We have storage-only billing when the VM is stopped (for only $0.073/GB/month) so that you aren't paying for compute when you don't need it. We also provide the ability to edit virtual machines after they’re created to downsize costs. If you provision a NVIDIA A6000 and find out you’re only using 50% of it, stop the VM, modify it to a NVIDIA A5000, and you’ll be billed the lower hourly rate without needing to recreate your server and migrate data over! Our infrastructure is built on 3x-replicated NVMe-based network storage, 10 Gbps networking, and 3 locations (New York, Chicago, Las Vegas) with more coming soon! - CPU-only servers from $0.027/hour - NVIDIA Quadro RTX 4000s from $0.29/hour - NVIDIA Tesla V100s from $0.52/hour - and 8 other GPU types that let you truly right-size workloads so that you’re never paying for more than you actually need We're starting off with $1 in free credits! Yes, we sound cheap… but $1 is all you need to get started with us! That’s more than 3 hours of compute time on our cheapest configuration! Use code HACKERNEWS_1 on the billing page to redeem this free credit :) TensorDock: https://ift.tt/ke6vKaL Product page: https://ift.tt/o7EtsVz API: https://ift.tt/7Kk5dwt Community CLI: https://ift.tt/ChxJbIN Deploy a GPU: https://ift.tt/GUBzjPK I'm here to answer your questions, so post them below!

Show HN: Equities.fyi – Startup valuations based on public company data With the current down markets, we were wondering what private company valuations looked like when compared to similar public companies. We were inspired by the a16z article ( https://ift.tt/qRhaolT... ) for calculating valuations and figured out the sales-to-valuation ratio of public companies at the time of the last fundraising round and applied the change in the public market to get the current startup valuation. If things don’t look right, our defaults might be off - please feel free to change those if they’re too different from what you’d expect. https://ift.tt/cVmXv9f July 28, 2022 at 10:57PM
Show HN: Looria – A product (re)search engine About 1.5 years ago, I introduced my review aggregator BuyForLife on Hacker News, where it became the #8 most upvoted Show HN project of all time[1]. The idea of helping people to make better purchasing decisions continued to chase me over the last year. Here are some stats that illustrate how important online reviews are: • 90% check online reviews as part of their online buying journey • 43% visit 5-10 websites to research a product • 75% spend more than a day doing research before buying a product The top frustrations with the current process are: • Google full of SEO spam and Ads • Fake reviews • Fragmented trusted sources • Inconsistent information across sources Thanks to the recent advances in NLP (transformers, GPT-3, etc.) it became possible to solve these problems at scale, so I decided to team up with my co-founders Johnny and Tavis to build https://Looria.com . We aggregate and summarize the most trusted product reviews on the web like Reddit, Youtube, or Consumer Reports. Just like Rotten Tomatoes provides trustworthy ratings for movies, Looria offers ratings and reviews for all kinds of products. Our vision is to make Looria the go-to platform for making purchase decisions. Let me try to answer a few questions that come up frequently: # Why should you trust this meta review site over the 100's of other meta or search sites and 10,000's of fake review sites on the web? -> We are completely unbiased and transparent. We are not affiliated with any of the businesses or products that we review, so we have no incentive to skew our ratings in any way. Our team has a deep understanding of the product review space and the specific problems that exist within that market. We're also solving our own problem after spending countless hours finding and researching good products. # Why can't I just go to Wirecutter or Consumer Reports directly? -> Most people don't trust anyone blindly and look at multiple opinions (4-7 websites on average). One single place will never be "just enough" for a product you're planning to use for a long time and spend quite some money on it. There is often at least one deal-breaking issue that you will find after reading through different sources. Many people rely on Reddit for reviews. Redditors and other forum members are more interested in boosting their ego by showing their depth of knowledge on the topic (and correcting others on the topic), whereas corporate websites are more interested in generating clicks. # How do you avoid fake reviews? -> Fake reviews are a big challenge that even platforms like Amazon don't have under control. Good fake reviews are technically almost impossible to detect, even with sophisticated network analysis of the reviewer's profile. We focus on keeping track of and removing the special status of sources caught getting paid to write fake reviews. Some categories are more prone to astroturfing than others, and we account for that by restricting the sources. Actively curating the sources is part of our daily work. # What are Exit Reviews? -> Another big frustration with product research is the lack of long-term product information. We should reflect upon how a product performed over its duration of service instead of when it first arrived and people haven't spent much time with it to learn the quirks. That's why we're building exitreviews.com - a community where people can learn how products performed over their lifetime, where they failed, and how to fix them. Looria is still in beta and our data is far from perfect. We're working hard on improving the data quality, adding better filters, and scaling to many more categories.

Show HN: TypeScript query builder with full type inference Hey HN! Colin here - a TypeScripter, open sourcer, and engineer at EdgeDB. As the creator of Zod and tRPC, I'm interested in designing tools/APIs that use type inference and generics to make life easier for devs. This query builder represents another step in that direction. We set out to build an EdgeQL query builder that can express queries of arbitrary complexity (EdgeQL has feature parity with SQL, roughly) and infer the static type of the query result. We introspect the database and generate a schema-aware client that represent any query, including ones that use built-in functions, operators, string/array/tuple indexing, aggregations, conditionals, type casting, subqueries, computed properties, etc—things most ORMs can’t represent. This post mostly discusses the API design, which I think will be interesting regardless of familiarity with EdgeQL. I’d love to see some of these ideas bleed into future generations of TypeScript ORMs/query builders too. Best way to try it is to clone the sandbox repo and follow the instructions in the README[0]. Or jump into the docs[1]. [0] https://ift.tt/RSNka7t [1] https://ift.tt/3azK0ty https://ift.tt/XJz83KI July 26, 2022 at 04:24PM
Show HN: PickCode – An educational coding environment for students after Scratch PickCode is designed for use on desktop and tablet, and supports creating chatbots, visual designs, and 2D games. There is plenty of functionality missing - you can't add media to games for instance, but the current version shows off the foundation of what I'm aiming at. I taught myself to code using MIT's App Inventor, so I have an enormous respect for block based languages like App Inventor, Scratch, Snap!, MakeCode, etc. PickCode is my attempt at adding options for students who want to learn more about programming without making the jump to text, or as an alternative to block coding for beginners coming to programming at an older age. The visual language is meant to lower the barrier to entry to coding but the far more important aspect for me is giving students the ability to make things they're proud of as quickly as possible. A JS/Python API for controlling the chatbot and game engine are in the works. As of now, there are sample programs to play with and an editor which saves your programs to local storage. Full user accounts, tutorials and administrator accounts for teachers to organize assignments are on their way soon. If you're interested in using PickCode in a classroom or want to discuss feedback, send me an email at charlie@pickcode.io https://ift.tt/tL2MZQX July 26, 2022 at 01:46AM
Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So I did just that =). I find hexagonal pipes a bit more difficult than the square variant because there's a larger variety of possible tile shapes. For an extra challenge I implemented wrap mode where the board can connect to itself (right to left and top to bottom), so there are no convenient outer walls to start from. The site is made with Svelte Kit, its code is available on github at < https://github.com/gereleth/hexapipes >. Hope you enjoy playing =). https://ift.tt/IYgyhbr July 25, 2022 at 12:20AM
Show HN: Redirect clicks using a formula Part of my day job requires me to review a report monthly. The URL for July's report looks something like this: fancyreport.com?from=2022-07-01&to=2022-07-31 Typing this URL manually every month was just enough pain for me to put up a simple script on somedomainiown.com/magic that redirected me to the report for the current month by automatically filling in the "from" and "to" values in the URL. This way, I could bookmark one link and always open the latest report with one click. At some point, I figured I should put this behind a UI so that I could share it with my colleagues and maybe HN too. A couple of weeks of hacking, and here we are with an MVP the little imposter inside me finally accepted to post online. P.S. the "formule" implementation gets the job done for me, but is pretty rudimentary. Would love to know if you have a specific use case that'd benefit from other parameters or a more advanced formula system. https://ift.tt/dtM7Pl9 July 25, 2022 at 02:35AM
Show HN: Zazow – Generative Art Toy (fractals, spirograph, satori, etc.) Im finally ready to share a fun side project that I've been working on. For 20 years, Ive been fascinated with Mandelbrot fractals. Back in the day, I made a MacOS9 app that rendered them, and I missed it. So, I decided to bring it up to the modern age and build a website to explore this and other similar fractals. In the process, I discovered some other types of generative art that looked fun, so I made those too. One is a spirograph, another is similar to an old AfterDark screensaver called Satori (anyone remember that?). Others draw paint splatters and random squiggly lines. The user is given a bunch of interactive settings to control how the artwork is generated. Im hoping to continue adding different styles of generative art to the website over time. Its a fun, relaxing project to work on and I hope other people enjoy using it to create pleasing images. https://www.zazow.com July 22, 2022 at 10:44PM

Show HN: I built an all-in-one virtual production platform for indies After being frustrated with the budget and learning curve requirements of the big names in the Virtual Production field, I decided to create my own all-in-one platform designed with beginners and less-technical folk in mind. It takes complicated tasks in other engines (tracking, compositing, floor plans, etc.) and makes them two-click solutions. And, with the free companion mobile app, you can track cameras, scan your sets, and (coming soon) do full body motion capture! There's a ton more features that I'm super proud of, and I'm open to any and all feedback! Thanks! Https://SceneForge.app July 21, 2022 at 03:43AM
Show HN: I built a handheld CHIP-8 game console to teach myself embedded systems A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier). But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to write all the firmware from scratch and even designed my first PCB, resulting in a finished (though not very polished) handheld CHIP-8 console. For those curious, the GitHub repo also has links to my dev blog about the project as well as a build guide. Thanks for looking! https://ift.tt/8APjd54 July 20, 2022 at 03:12AM
Show HN: Ex Platform for SWEs Hey guys, just sharing this project that I've been working on. Let me know what you think. This idea came primarily from my own experience in the software industry. After a while, I was feeling discouraged by my job, mostly because I felt expendable (like a code monkey), burned out, and had unchallenging work. It felt like the employers I was working for didn’t have an idea of what was going on or how their employees were feeling. They would talk a lot about the technical challenges, but never did we talk about any mental/emotional challenges. So I started thinking about what could be done to mitigate this problem and came up with this solution. An employee experience platform that tracks multiple psychological dimensions (specifically customized to track problems that can be faced in a software engineering environment) and gives the managers some insights into their teams/employees. I'm still currently working on the MVP but would love to hear what you guys think about the idea and landing page. The MVP should be out in 2-3 weeks from now. https://smartteams.ca/ July 17, 2022 at 01:24AM

Show HN: Eesel – Federated search without API integrations Hey there! Amogh here from eesel ( https://eesel.app ). eesel filters your browser history to show the docs you need for work, right in your new tab. You can see recent docs, filter by app or search by title or content. We're trying to solve a pretty universal problem. Everyone's work is spread across apps - there's a project brief in Google Docs, issues in Jira, a mockup in Figma, PRs in GitHub - and with this kind of sprawl, it can be a game of trial and error to find the links we need to do our job. Trying keywords in the address bar only works if we remember the title and it's specific enough, search in apps can be slow and noisy, company "knowledge hubs" in Confluence or Google Drive are usually not up to date, and we ultimately just ping each other on Slack to find things. I was struggling with this acutely as a PM at Intercom, and it felt ridiculous that I could search the web faster than my company's docs. It was around this time that I also discovered an Effective Altruism blog post on Operations ( https://ift.tt/DZvefq1 ) and how "maximising the productivity of others in the organisation" can have this multiplier effect for your own impact. That's when it clicked - here's an "operations" problem that felt tractable for my skills and I could potentially multiply my impact by solving it. This is what gave the conviction to prototype something on the weekends, and things spun off from there. Let's talk about the solution more. The magical thing about eesel is that we don't use APIs. When it comes to "search across apps", integrating with different APIs is a pretty default way to approach things. That's how we started, but things felt uneasy - could we really build API integrations with _everything_? There's so much out there, and this list is pretty much always changing. If we really did want a search across all work apps, we'd have to play catch up with old and new APIs. You could argue that these were just the schleps ( https://ift.tt/Ud79qkD ) we had to overcome, but it was amidst this we realised that uh, the browser exists. We mostly work in the browser, and the great thing about it is that it's built on web standards. From HTTP and URLs to HTML and CSS, all apps in the browser follow the same predictable patterns: documents are accessed via URLs, content lives inside the HTML, there's a page title, there's a favicon, and so on. It's not a perfect replacement for APIs, but it felt good enough. We didn't need to manually integrate with each app, and could instead rely on existing web standards. And that's what we did. eesel works with any app in the browser, including apps without APIs (like that internal company tool), or apps that don't exist yet (the new Product Hunt hit). Not using APIs also meant that we could go an extra step with privacy - eesel works fully locally by default and you don't need to login to _anything_ (even eesel!). Simply install and it works. We want to keep building on this approach and improve how we work in the browser. For instance, eesel uses keywords to automatically organise pages into Folders, and there's Commands to take actions (spoiler: you can customise a JavaScript to inject on a page, like this script that goes to a Notion backlog and clicks the "New" button - https://ift.tt/8Ceq3ZI... ). Alright, that's a lot of writing from us. We have a bunch of ideas, and would love to hear about where you think we should take this next. https://www.eesel.app/ July 15, 2022 at 05:44PM
Show HN: Mapedia.org – A Crowdsourced Learning Map Hi HN! We're happy to announce the launch of Mapedia.org, an open source crowdsourced learning map! Mapedia is a new kind of learning platform at the crossroad between Wikipedia, Google Maps and Khan Academy: a learning map built collaboratively to support online learners to learn any topic seamlessly. We built an interactive learning map of topics to be able to visualize the different fields of knowledge, what concepts are included in them and how they relate to each other. This allows for curiosity based exploration, identifying knowledge gaps (unknown unknowns) and figuring out what to learn next (and in which order). For each topic you can then find community and expert curated resources, learning advices and smart recommendations in order to learn as efficiently as possible. We want people to spend time learning rather than figuring out how to learn, and in particular to empower self-directed learners. The idea came out of the frustration and inefficiency of learning online, and I've been working on it for 2 years now. The vision in itself for it is not so new, Mapedia is rather a different take on it that particularly believes in the potential of crowdsourcing and online communities. Our roadmap includes implementing learning groups based on shared goals rather than shared course/learning material, customizable "constructive" feeds of learning materials and adaptive learning paths. The topic map is obviously far from complete and we are still in the early product iterations, but you can checkout a few examples here: https://ift.tt/U9eVA32 -> The explore map from the top level topics https://ift.tt/uphciXS... -> the map focused on functional programming, showing how concepts relate to each other https://ift.tt/36FQTPy... -> the page for the functional programming topic, with curated resources https://ift.tt/IOdBnNs... -> an example of a learning path (this feature is in a very alpha version) Let us know what you think! We're very open to feedback and suggestions https://mapedia.org/ July 15, 2022 at 11:57PM
Show HN: App to help with planning, producing, reviewing, and publishing video Hey everyone, I've started working on an app to help companies, freelancers, and even individual content creators plan, produce, review, and publish their videos and streams in a more organised way. We're just getting started so not trying to sell anything at this point, but I do need feedback on where we're headed. I recorded a video walkthrough of some mock-ups at https://www.youtube.com/watch?v=mTtB_EkUA-M, or you can take a look at them yourself at https://ift.tt/za751Vr (it is somewhat self-explanatory, but in the video I add more context). You can think of it as a potentially better, more organised alternative to having a bunch of stuff in random Google Docs and other places that you have to pass back and forth. I also eventually expect to add a lot of automatic post-processing type features (captioning, lighting/sound adjustments, "umm" removal, etc.) for people who don't know how to do that on their own. Any kind of feedback at all is welcome, positive or negative, on whether there's an idea here that you think I could develop into something people would pay for, or if there's something you'd like to see in an app like this. Thanks in advance! July 14, 2022 at 05:15PM
Show HN: Typewaiter, the typewriter that doesn't wait Howdy HN, just recently made this silly typewriter variant and think some of you might enjoy it so thought I'd share. Here the cursor takes no heed of what you're typing and just advances at a steady pace, with the effect that typing something reasonable-looking requires you to type at a very steady rhythm. There's also the bonus that the space character is no longer needed—you can (and kind of have to) just wait—so the keyboard minimalists among us can shave even more space off their devices. Only desktop for now. It's an interesting contrast to the last one I made—which requires you to do all the heavy lifting in moving the cursor position yourself— https://ift.tt/VxK42dZ https://ift.tt/tRUF0Z1 July 11, 2022 at 03:57AM
Show HN: Evryca – fractal thinking tool to brainstorm and organize thoughts Made a tool to organize thoughts. Actually it is a mind tree, but in a more web-friendly form. It has pivoted from what I originally started building at evryca.com. Some years ago I got the idea of fractal conversation, instead of old-school tree/ladder-like comments. I wanted to see only comments related to the current level. I started making "something" with fractal comments. This "something" was a project discussion platform. But it turned out that even I myself don't use it, and the idea of fractal comments stuck there unused. And recently it dawned on me that it may be a conversation with yourself — thinking, brainstorming, taking notes, writing. So made this kind of cork/whiteboard, where one can dive into the subject and, being in the flow, write and see only related notes and rearrange them later. I'm trying to make it flawless and add keyboard shortcuts where it's possible (Ctr+Enter to submit idea, drag-and-drop to rearrange, Esc to jump level up). So finally I've made a tool that I use myself and will update it gradually (sorting, touch devices, ex/import (json, text), boards, more navigation with keyboard and other stuff, and login). https://www.evryca.com/ July 9, 2022 at 03:03PM
Show HN: I made a small Space Shooter Thank you https://opengameart.org for your service. People like me who can't draw or compose music are in your debt. The game, "Glitch and Rush" has been made in a few hours here and there. I've been tinkering in GameDev for years, if not decades, but I never released anything. The goal here was simple: - come up with a core mechanic - implement a single level - add some polishing - RELEASE I hope you'll enjoy it. BTW, my best time is 2min23s (yes, I'm bad at my own game, it's ok, I'm ok). https://ift.tt/SwrLDBF July 9, 2022 at 02:28AM
Show HN: I made an app to help insomniacs learn how to sleep again Hi HN! I suffered from chronic insomnia for over a year and tried everything from cutting coffee, blocking blue light, to taking melatonin and antihistamine, but couldn’t find anything that worked. I even bought a $500 research-grade EEG device to track my sleep, which was honestly kind of depressing because it showed that I was sleeping less than 4 hours per night for weeks straight. In the day, it took an immense amount of energy for me to perform even the most mundane of tasks, such as doing my laundry or ordering groceries. At night, I felt an overwhelming sense of loneliness and resentment as I lay in bed wide-awake, reading and re-reading Sleep by Murakami or mindlessly scrolling through reddit/ HN. My performance at work suffered, my personal relationships suffered, and my happiness suffered. When I finally decided to see a sleep specialist, I was put on a 3-month long waiting list. Eventually, I was able to get my insomnia treated, but I realized that there is no reason why anyone should wait 3 months to get treatment when the same therapy that I received can be delivered online. My co-founder and I both have experience in digital health, so we decided to partner with sleep experts to create a mobile app to help people with insomnia get better sleep using psychology. We launched in February this year, and have already helped over 500 patients improve their sleep permanently. Our data shows that our program is just as effective as group, in-person sleep therapy, and we’re doing a clinical study with Brigham and Women’s hospital and Harvard Medical School to prove the efficacy of our product. On average, our users sleep 74 minutes longer than before and spend 52% less time awake in the middle of the night. If you have trouble with sleep, try our app and let us know what you think! https://slumber.one July 8, 2022 at 07:53AM
Show HN: PostgreSQL proxy for integration testing things you don't control Hi hackers! I recently tried to get a stack of microservices running in a docker-compose sandbox for integration testing using their original (e.g. prod) configuration. This means I didn't know what credentials they'd be using or what database name. So I hacked together a postgresql proxy using an existing project ( https://ift.tt/TqBX8ve ) and simply allow any credentials to connect and make sure the desired database exists before returning control to the caller. Sharing this in the hopes it is useful for someone else. Lucas https://ift.tt/ms1TBEA July 8, 2022 at 12:12AM
Show HN: Barfi – Python flow based programming with GUI What? Another flow based programming library for Python? Yes. All the FBP libraries out there for Python need to be run as a self contained application. They are not components that could be integrated into your existing data workflows. Barfi, on the other hand can be integrated. At the moment it has a Streamlit component that you can use in your Streamlit apps. Currently, I am working on a Jupyter notebook widget. https://ift.tt/nZWbd0C July 7, 2022 at 02:30AM
Show HN: C3 – A C alternative that looks like C Compiler link: https://ift.tt/czU4tGx Docs: http://www.c3-lang.org This is my follow-up "Show HN" from roughly a year ago ( https://ift.tt/SMC6yEY ). Since then the language design has evolved and the compiler has gotten much more solid. Assorted extra info: - The C3 name is a homage to the C2 language project ( http://c2lang.org ) which it was originally inspired by. - Although C3 mostly conforms to C syntax, the most obvious change is requiring `fn` in front of the functions. This is to simplify searching for definitions in editors. - There is a comparison with some other languages here: https://ift.tt/rfQYvuG - The parts in C3 which breaks C semantics or syntax: https://ift.tt/XyKlDzN - Aside from the very C-like syntax, one the biggest difference between C3 and other "C competitors" is that C3 prioritizes C ABI compatibility, so that all C3 special types (such as slices and optionals) can be used from C without any effort. C and C3 can coexist nicely in a code base. - Currently the standard library is not even alpha quality, it's actively being built, but there is a `libc` module which allows accessing all of libc. Raylib is available to use from C3 with MacOS and Windows, see: https://ift.tt/mRzilS4 - There is a blog with assorted articles I've written during the development: https://ift.tt/TxIcFJL July 7, 2022 at 01:01AM
Show HN: Graphsignal – ML profiler to speed up training and inference Hi, Graphsignal founder here. We've launched Graphsignal earlier this year to make machine learning profiling practical and easy to use. Basically, it enables the profile-optimize-benchmark loop. For example, making inference faster by optimizing an ML model, while still maintaining accuracy. We've make a lot of progress that I wanted to share. The profiler now natively supports TensorFlow, Keras, PyTorch, PyTorch Lightning, Hugging Face, XGBoost and JAX frameworks along with built-in support for distributed workloads. Profiles now include tracing information in chrome trace format. Process and GPU utilization data has been extended as well. It is now possible to monitor all run metrics. Useful for long runs. Profiled workloads are now sharable across teams and publicly (if enabled). I'm excited to show it here and appreciate any thoughts, comments and feedback! https://ift.tt/PoULa7h July 4, 2022 at 05:10PM
Show HN: Trane, an automated system for learning complex skills Hi HN, I released Trane over the weekend: https://ift.tt/m1QxKyh . Trane is an automated system for learning complex skills. Think of it like defining a skills tree (technically a graph) of all the smaller skills you need to master a complex skill and having an automated system to automatically traverse the graph as you master them. The seed for Trane was planted after my frustration trying to learn music, and jazz in particular. There are simply too many things you need to master first (e.g. knowing the names of a note, knowing where the notes are in your instrument, timing, etc) and it becomes difficult to track what it is that you should focus on, and there is a process of constant atrophy, even if you practice consistently. Trane is an early state, but is already usable. I have released a command line interface at https://ift.tt/oiDr8pI and some music courses at https://ift.tt/wS5MyRH . I would like to get some ideas in regard to what other skills could be a good fit for Trane. I am thinking chess, programming, or languages could be a fit. I am wondering if Trane could be applied to something like learning pure mathematics. I would love to hear any suggestions. Perhaps there's some of you who have found a similar issue while practicing your own hobbies. https://ift.tt/m1QxKyh July 4, 2022 at 11:34PM
