Show HN: Perfect Pitch Puzzle – a musical Wordle daily ear training game
Hi all! Thanks for checking out the side project my family and I have been working on (on and off) for the past year. We were playing wordle when we thought: wouldn't it be fun if you had to guess musical notes (ABCDEFG) instead of words? And what if the notes you had to guess were actually the first six notes of a familiar melody?<p>My brother and I both have perfect pitch, which has been really helpful when we want to cover a song that we like, or improvise in a jazz or blue grass setting. We don’t promise that this game will help you gain perfect pitch, but it <i>is</i> possible to train your ear to more accurately gauge sounds, and our hope is that this game will help with that.<p>So far we’ve gotten feedback from consistent players that the game <i>has</i> helped non-musicians more easily identify notes based on relative pitches, and helped even musicians improve their ability to remember tunes better, which is good to hear.<p>The game has evolved with different instruments and difficulty modes (easy, normal, hard), but the essence has remained the same:
- One new musical puzzle a day
- The octave moves with the melody, so you don’t need to worry about the octave; you just need to guess the pitch<p>There are a few things we want to improve as well, like:
- improved mobile support (especially Android)
- a “practice mode” - allow users to play more than one game per day, or multiple variations of notes, with visual feedback on how close they were to guessing the note
- making it easier to add new songs to the database (currently it takes 5-10 minutes to code in a new song)
any other feedback that we get here or in our Discord. :)<p>PS. If you already have perfect pitch or want to challenge yourself to the impossible, I'd recommend playing the "bird_tweet" instrument in "hard" mode!
Show HN: IP Guide – Info on IP addresses, Networks, and ASNs
Hey all, wanted to share my recent weekend hack project. I wanted to improve upon the existing space for looking up information about IP addresses and ASNs.<p>The backend is written in Rust and pulls BGP data every 8 hours from the RIPE RIS project to build up a routing table and also adds geolocation information. The frontend is using React and Tailwind.<p>Would love any feedback or suggestions on what to improve.

Show HN: New visual language for teaching kids to code
Pickcode is a new language and editor for getting kids started with coding. The code editing experience is totally structured, where you select choices from menus rather than typing.
I made Pickcode after experiences teaching kids both block coding (Scratch, App Inventor) and Python. To me, block coding is too far removed from regular coding for kids to make the connection. Pickcode provides a much clearer transition path for students to Python/JS/Java. Our target market is middle/early high school kids, and that’s who we’ve tested the product with during development.<p>On the site, you can do tutorials to make chatbots, animated drawings, and 2D games. We have a full Intro to Pickcode course, as well as an Intro to Python course where you make regular console programs with a regular text editor. There are 30 or so free lessons accessible with an account, and the rest are paywalled for $5/month.<p>For professional programmers, the editor is probably pretty frustrating to use (no vim keybindings!), but I hope it’s at least interesting to play with from a UI perspective. If you have kids aged 10-14, I’d love any feedback you have from trying it out with them. I love talking to users, reach out at charlie@pickcode.io!

Awesome Engineering Games
I've spent way too much time both playing and finding engineering-focused games, and haven't been able to find very detailed or comprehensive lists online. So I made one :)<p>These games are both fun and often quite educational, presenting gamified versions of real-world challenges and professions.<p>There's a lot of different sub-genres of "engineering game", such as:<p>* Factory automation (Factorio, Dyson Sphere Program)<p>* City builders (Cities: Skylines, Anno series)<p>* Route-builders (Mini Motorways, Railway Empire)<p>* Comp sci (TIS-100, Bitburner)<p>All games on the list are very highly reviewed. I've played most (but not all) of them, and provided personal recommendations alongside the reviews. Many of them are also playable on GeForce Now (if you don't have a gaming PC).<p>Please contribute if you know of more, or have any comments/suggestions!
Show HN: YouTube banned adblockers so I built an extension to skip their ads
Hi HN!<p>Since Youtube no longer allows AdBlockers, I built my own extension to get around their video ads. If there is an ad it temporarily manipulates the video; Mutes the volume, sets speed to 10x, and skips it if there is a button.<p>Chrome Webstore link: <a href="https://chromewebstore.google.com/detail/ad-accelerator/gpboiedfklodfhngobidfjecdpmccehg?hl=en" rel="nofollow noreferrer">https://chromewebstore.google.com/detail/ad-accelerator/gpbo...</a><p>Code: <a href="https://github.com/rkk3/ad-accelerator">https://github.com/rkk3/ad-accelerator</a>

Show HN: Open-source tool for creating courses like Duolingo
I'm launching UneeBee, an open-source tool for creating interactive courses like Duolingo:<p>GitHub repo: <a href="https://github.com/zoonk/uneebee">https://github.com/zoonk/uneebee</a>
Demo: <a href="https://app.uneebee.com/" rel="nofollow noreferrer">https://app.uneebee.com/</a><p>It's pretty early-stage, so there's a lot of things to improve. Everything on this project is going to be public, so you can check the roadmap on GitHub too: <a href="https://github.com/orgs/zoonk/projects/11">https://github.com/orgs/zoonk/projects/11</a><p>I'm creating this project because I love Duolingo and I wanted the same kind of experience to learn other things as well.<p>But I think this could be useful to other people too. I'll soon launch three products using UneeBee:<p>- Wikaro: Focused on enterprise. It allow companies to have their own white-label Duolingo. I think this is going to be great for onboarding and internal training.<p>- Educasso: Focused on schools. It will allow teachers to easily create interactive lessons, compliant to local school curriculum. I want to make it in a way that saves teacher's time, so they focus more on their students rather than lesson planning.<p>- Wisek: Marketplace for interactive courses where creators will be able to earn money creating those courses.<p>I'm not sure this is going to work out but, worst case scenario, I'll have products that I can use myself because I'm a terrible learner using traditional ways. Interactive learning is super useful to me, so I hope it will be to other people too.<p>If you have some spare time, please give me your brutal feedback. I really want to improve this product, so no need to be nice - just let me know your thoughts. :)<p>PS. I'm also launching it on Product Hunt: <a href="https://www.producthunt.com/posts/uneebee" rel="nofollow noreferrer">https://www.producthunt.com/posts/uneebee</a>

Also, yes I am looking for a new role. And yes, I should have been spending my time looking for suitable roles instead of building this.

Show HN: Convert any screenshot into clean HTML code using GPT Vision (OSS tool)
Hey everyone,<p>I built a simple React/Python app that takes screenshots of websites and converts them to clean HTML/Tailwind code.<p>It uses GPT-4 Vision to generate the code, and DALL-E 3 to create placeholder images.<p>To run it, all you need is an OpenAI key with GPT vision access.<p>I’m quite pleased with how well it works most of the time. Sometimes, the image generations can be hilariously off. See here for a replica of Taylor Swift’s Instagram page: <a href="https://streamable.com/70gow1" rel="nofollow noreferrer">https://streamable.com/70gow1</a> I initially had a hard time getting it to work on full page screenshots. GPT4 would code up the first couple of sections and then, get lazy and output placeholder comments for the rest of the page. With some prompt engineering, full page screenshots work a whole lot better now. It’s great for landing pages.<p>Lots of ideas of where to go from here! Let me know if you have feedback and you find this useful :)
