Show HN: I made a little math game named Summle
I made this game for my children to play, as they are heavily into Wordle, and I thought they'd also like something maths based!<p>Every puzzle is solvable and has at least one solution (usually more).<p>There is a kids mode in the settings, plus a hard mode for extra difficulty.

Show HN: DontBeEvil.rip: Search, for developers (API, expressions, CLI)
I'd like to invite everyone to try out DontBeEvil.rip, an experimental search engine for developers.<p>tl;dr<p>$ alias rip="curl -G -H 'Accept: text/plain' --url <a href="https://dontbeevil.rip/search" rel="nofollow">https://dontbeevil.rip/search</a> --data-urlencode "<p>$ rip 'q=Heartbleed bug'<p>DontBeEvil.rip is a year long experiment to see if a small team can build a developer-focused search engine that is self-sustaining on $10 monthly subscriptions.<p>It works by only indexing high-quality resources that are relevant to developers. You won't get useless listicles because we'll never crawl them. Relevant urls are harvested from HN, StackOverflow, programmer Reddit, and a few others. Page content comes mostly from the Common Crawl project.<p>The limited, but awesome, features in this first release are:<p>- Expressions! Experience the power of Elasticsearch’s Simple Query Strings.<p>- REST API. Just change 'text/plain' to `application/json` in the above alias.<p>- CLI. Just use curl in the terminal. Simple as.<p>HackerNews, StackOverflow, Arxiv abstracts, 2M Github repos, and programmer Reddit (up to 2020) are being indexed right now. There's much more to come in the next few months.<p>I'd love to hear your questions, comments and suggestions in the comments below.

Show HN: I made a web game called Almost Pong
Hi HN!<p>I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong.<p>This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code.<p>Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
Show HN: A more social, Amazon-free alternative to Goodreads
Hey HN, I know reading books isn’t everyone’s thing, but it’s certainly been mine for as long as I can remember.<p>Unfortunately, I felt like the online book space was missing a platform that does the book community justice. Goodreads is the go-to "social platform", but if you've been on Goodreads before, you'll probably agree that it's not all that social, and overall not all that exciting.<p>So I set out to build what I personally was looking for (but could never find). The goal: to give the book community a more social and streamlined alternative to Goodreads or StoryGraph.<p>We also felt like it was important for Booqsi to be independent of Amazon; we care about supporting local bookstores, so every book in Booqsi links you to Bookshop.org to purchase that book (not Amazon).<p>Here are some of my favorite features launched as part of beta:<p>- A book-focused social feed (finally!)<p>- Beautifully-rendered custom bookshelves to show off to your friends<p>- Streamlined book recommendations to friends<p>- Easily track reading goals and books you've read<p>And many more...<p>It's completely free and easy to use, and we would love your feedback as you explore the platform.

Show HN: Cloning a musical instrument from 16 seconds of audio
In 2020, Magenta released DDSP [1], a machine learning algorithm / python library which made it possible to generate good sounding instrument synthesizers from about 6-10 minutes of data. While working with DDSP for a project, we realised how
it was actually quite hard to find 6-10 minute of clean recordings of monophonic instruments.<p>In this project, we have combined the DDSP architecture with a domain adaptation technique from speech synthesis [2]. This domain adaptation technique works by pre-training our model on many different recordings from the Solos dataset [3] first and then fine-tuning parts of the model to the new recording. This allows us to produce decent sounding instrument synthesisers from as little as 16 seconds of target audio instead of 6-10 minutes.<p>[1] <a href="https://arxiv.org/abs/2001.04643" rel="nofollow">https://arxiv.org/abs/2001.04643</a><p>[2] <a href="https://arxiv.org/abs/1802.06006" rel="nofollow">https://arxiv.org/abs/1802.06006</a><p>[3] <a href="https://arxiv.org/abs/2006.07931" rel="nofollow">https://arxiv.org/abs/2006.07931</a><p>We hope to publish a paper on the topic soon.

Show HN: Supernotes 2 – a fast, Markdown notes app for journalling and sharing
Hi HN – we first launched Supernotes[1] to HN in April 2020, and since then Tobias and I (it's just the two of us) have put in the work to make what we hope is an amazing note-taking app. Although the note-taking / personal knowledge management landscape is <i>incredibly</i> competitive at the moment (with lots of great apps adding great new features every day), we think that with the newly released Supernotes 2 we're keeping pace and delivering a unique and satisfying knowledge management experience.<p>Here's the combination of features that make us stand out:<p>- a powerful markdown-based notecard system that is simple/beautiful but also super flexible<p>- a WYSIWYM[2] editor that keeps markdown marks for explicitness while still giving you a preview of what the content looks like when rendered<p>- eschewing a folder system in favor of multi-parent nested hierarchies<p>- unique collaboration system that is optimized for granular sharing between individuals rather than "all-in" sharing amongst teams or specific groups<p>- notes that can be linked both with inline bidirectional links or the aforementioned hierarchies, allowing you to build (and <i>experience</i> with our 2D and 3D graph views) a robust graph of your knowledge<p>There are of course tons of other cool features that are included as well, but those are the highlights. If any of that sounds interesting to you, you can sign up here[3] – we would love to hear any feedback you might have!<p>[1] <a href="https://supernotes.app/?ref=hn" rel="nofollow">https://supernotes.app/?ref=hn</a><p>[2] <a href="https://en.wikipedia.org/wiki/WYSIWYM" rel="nofollow">https://en.wikipedia.org/wiki/WYSIWYM</a><p>[3] <a href="https://my.supernotes.app/entry?signup=1&ref=hn" rel="nofollow">https://my.supernotes.app/entry?signup=1&ref=hn</a>

Show HN: I Designed and Built an eBike
This post shows and explains the design of the eBike I built myself. I decided to post it on this specific forum because this is where it all started, by stumbling on another post, as mentioned in my entry.
