Show HN: I made a cross-platform command-line music player called maestro https://ift.tt/5x8ZYFl

Show HN: I made a cross-platform command-line music player called maestro It is built to work on Windows, Mac, and Linux, and was tested thoroughly on my Mac and lightly on my friend's Windows. Unfortunately, no one I know uses Linux. It works with WAV, MP3, FLAC, and Ogg Vorbis files. https://ift.tt/Q5iOSHV August 7, 2022 at 06:24AM

Show HN: A Gauss-Seidel solver visualization in a single HTML file https://ift.tt/QW50zRn

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. You can save this single file and double click it to run. - A math typesetter from scratch in C that compiles/renders the equations in real-time (uses KaTex fonts and STB true type to rasterize the fonts). - Platform code is done using Sokol (tested on windows and web). - The UI is done using Dear ImGu

Show HN: Minimal Static Site Generator https://ift.tt/X6uyw32

Show HN: Minimal Static Site Generator `pandoc-sitegen` uses pandoc and mustache templating to turn a bunch of markdown files into a minimalist site, while still allowing for things like an automatic list of blog posts. I was really frustrated with the complexity of most existing static site generators like Jekyll and Hugo -- it seemed like even a basic blog required an immense amount of configuration and provided tons of features I didn't need. I built this mostly for myself, but I'd love any feedback on it :) https://ift.tt/N8T6hcj August 6, 2022 at 03:25AM

Show HN: A link/news aggregator I am working on https://ift.tt/osJwYB2

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 li

Show HN: I created a browser automation tool https://ift.tt/ky9ztiR

Show HN: I created a browser automation tool I created this tool a few months ago to automate some of my tasks. I use it to collect prices and files and to get notified when something changes on certain websites. The task runner uses Playwright. I'm not sure if it can be useful to anybody else besides me :) Any feedback is welcome. https://ift.tt/g6aTLkV August 5, 2022 at 11:58AM

Bayshore Boulevard Quick-Build Project Update

Bayshore Boulevard Quick-Build Project Update By Adrienne Heim Bayshore Boulevard is a mixture of industrial and commercial ruggedness mixed with historic and family run small business charm. Bayshore Boulevard is also a busy street that runs parallel to Highway 101 and is nestled between Bayview, Bernal Heights, Potrero Hill and Mission neighborhoods. Interestingly enough, one of the oldest restaurants in San Francisco, The Old Clam House , built in 1861 and recently re-opened after two years of closure due to the pandemic and management changes. As you begin to walk Bayshore and Oakdale heading south towards Silver Avenue, you’ll see workers grabbing food and saying hi to owner Tarik at Bayshore Taqueria, you’ll notice parents dropping off their children at the family run business American Gymnastics Club and folks walking to catch the 9 or 9R Bayshore or 23 Monterey Muni bus. For over 30 years, people have been visiting legacy business Flowercraft Garden Center , near Bayshore an

Show HN: Not8 – continuous product improvement platform https://ift.tt/IcVYS24

Show HN: Not8 – continuous product improvement platform My co-founder and I are taking part in the acceleration program, and we're building not8 - a platform for team product reviews and user feedback collection. Right now we already have an MVP which is a Chrome extension that allows you to leave 'sticky notes' on live websites and share them in just one click. Our demo day is going to be in ~2 weeks, and we want to our user count to hit 1000 by that time. Actually, we want it so much that we are ready to offer our first 1000 users a forever free access to our product. Try out our extension now, and share a few notes with your team - I hope, you will love it. Here's how it works: https://ift.tt/QtuipHg Here's where to download it: https://ift.tt/mco3WhO August 5, 2022 at 06:10PM

Show HN: 3D Topography of Your GPS Track https://ift.tt/ydDEUj4

Show HN: 3D Topography of Your GPS Track As a hiker and (ski)mountaineer I've always been a bit disappointed of how most apps fail to properly depict the topography while analyzing GPS tracks. (I know that Strava offers some kind of 3D view by now, but I still wanted to build my own thing) That's why I started working on https://cubetrek.com It's still very experimental, but you can give it test-drive now. Any feedback appreciated. It essentially renders your GPS Track as a 3D model within the topography. As an example, here's the Bishorn, a 4000 m peak in Switzerland: https://ift.tt/39VFXPo The front end is based on Babylon.js, D3.js, the back end is Spring Boot and Postgresql with PostGIS. There's a summary on how it works at the very bottom of the homepage. https://cubetrek.com August 5, 2022 at 07:57AM

Show HN: Score In URL, a sheet music editor that store everything in URL https://ift.tt/EpN3vMW

Show HN: Score In URL, a sheet music editor that store everything in URL I'm excited to publish my new project, [Score In URL]( https://ift.tt/Qb9VDN4 ), a simple, privacy-friendly, sheet music sharing service, where the entire content is encoded in the URL itself as a query parameter. It comes with a decent text editor, rendered score, and audio. The sheet music is notated with ABC Notation, rendered by abcjs. This project is heavily inspired by [Hashify]( https://hashify.me ), which encodes a markdown document into its URL. The code is here: https://ift.tt/ZjksxRu I made this with ViteJS and Tailwind CSS, and hosts it with GitHub Pages. I'm not proficient in front-end development at all, my past experience in this area being basically vanilla HTML/CSS, with a tiny bit of JS. This is in fact my first try at using any front-end framework. I sincerely welcome all feedback. The idea came to me when I tried to convey the idea of an exercise in a music forum. No forum I've used

Keeping Muni Riders Safe

Keeping Muni Riders Safe By Andrea Buffa After several years without a major violent incident on Muni, we’ve recently experienced two tragic shootings. On June 22, two passengers got into an altercation, and one of the passengers fatally shot another passenger and injured a bystander. The shooter was quickly apprehended by the San Francisco Police Department (SFPD) thanks to our collaboration and use of clear, state-of-the-art surveillance cameras on board our vehicles. On August 3, there was a targeted shooting on a Muni vehicle driving through the Sunnydale neighborhood; one passenger was killed, and a bystander sustained a minor injury. SFPD’s Homicide Detail is investigating the incident, and we are fully cooperating by providing the SFPD with onboard and street-facing video data.  We offer our deepest sympathies to the victims and their families who are suffering right now.   While these recent incidents appear to be an anomaly and instances of isolated, targeted confrontation

Show HN: Penumbra, a perceptually optimized color palette based on natural light https://ift.tt/xRuMhof

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/TKQDeW6 August 5, 2022 at 03:23AM

Show HN: Butt Mover - A butt triggered productivity and health improvement game https://ift.tt/iGIYACo

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 mysel

Show HN: MutableAI (YC W22) – Copilot Alternative for VS Code https://ift.tt/vRdaTzg

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) [1]. In addition to autocomplete, which can be triggered either automatically or manually, we can add documentation to all your methods in a Rust file, o

Show HN: Simplenote – Notes with support for publishing (hosted, Markdown) https://ift.tt/furhUF0

Show HN: Simplenote – Notes with support for publishing (hosted, Markdown) I use Simplenote for journaling and creating itineraries for my wife and I (publish as a webpage and send link). It's great. Robust export options too. I used to use Obsidian + iCloud sync daemon to facilitate continuity between my Windows desktop and my Macbook, but I started getting sync issues on Windows and a couple BSODs due to how the iCloud daemon handles timestamps. I picked up Simplenote and it's been working flawlessly. Very underrated IMO. https://simplenote.com/ August 2, 2022 at 08:47PM

Show HN: Emery – Personal productivity workspace https://ift.tt/GBlI0QV

Show HN: Emery – Personal productivity workspace We're building an app that helps people manage their schedule, tasks and notes all in one place. The goal is to create a workspace, where people can manage their various priorities, both personal and professional, see a single schedule combined of all their calendars and manage their days without switching between multiple apps. 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 03:42AM

Show HN: Rentaflop – Render your Blender projects without sacrificing quality https://ift.tt/OA4bt9R

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

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/At4nvOe P.S.: The puzzles come from https://ift.tt/ip9RrWV (the author is credited and has been contacted before using them). https://ift.tt/dq9BLIC July 31, 2022 at 11:31PM

Show HN: I've been making JavaScript sandbox alone for 6 years https://ift.tt/tfdKiET

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 10:27AM
