Show HN: Glidesort, a new stable sort in Rust up to ~4x faster for random data
Hi all, I've talked about glidesort a few times on HN already, but it's finally ready for release. If you have any questions, feel free to ask. An academic paper on glidesort that goes into a lot more detail than the readme is upcoming, but is not ready yet.<p>I will be giving a talk on glidesort tomorrow at FOSDEM 2023 in the Rust Devroom at 16:10, you can seek me out there as well. In other news, I am leaving academia soon, so if you have interesting (Rust) jobs the coming months feel free to approach me.

Show HN: DriftDB – an open source WebSocket backend for real-time apps
Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB.<p>In addition to the open source server that you can run yourself, we also provide <a href="https://jamsocket.live" rel="nofollow">https://jamsocket.live</a> where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY).<p>You may have seen my blog post a couple months back, “You might not need a CRDT”[1]. Some of those ideas (especially the emphasis on state machine synchronization) are implemented in DriftDB.<p>Here’s an IRL talk I gave on DriftDB last week at Browsertech SF[2] and a 4-minute tutorial of building a cross-client synchronized slider component in React[3]<p>[1] <a href="https://news.ycombinator.com/item?id=33865672" rel="nofollow">https://news.ycombinator.com/item?id=33865672</a><p>[2] <a href="https://www.youtube.com/watch?v=wPRv3MImcqM">https://www.youtube.com/watch?v=wPRv3MImcqM</a><p>[3] <a href="https://www.youtube.com/watch?v=ktb6HUZlyJs">https://www.youtube.com/watch?v=ktb6HUZlyJs</a>

Show HN: I trained an AI model on 120M+ songs from iTunes

Show HN: Sudoku with 0 Bells or Whistles
Hello HN,<p>I've created a new Sudoku app for iOS and Android that prioritizes simplicity and privacy. It's free to download and use, and I'd be grateful for any feedback or suggestions.<p>Features:<p>> 4 difficulty levels, accessible at any time<p>> No personal data collection of any kind<p>> Clean, minimalistic design that focuses on the game<p>> Takes up significantly less space than other popular apps (by a factor of about 10x)<p>> Minimal use of advertisements<p>I was frustrated by how many of the popular Sudoku apps feel excessively over-engineered, consume a lot of storage space and some that even collect unnecessary personal information, like location and contacts. So I put this app together without any of those things (using flutter).<p>Links:<p>iOS: <a href="https://apps.apple.com/app/sudoku-puzzle-palace/id1668683822" rel="nofollow">https://apps.apple.com/app/sudoku-puzzle-palace/id1668683822</a><p>android: <a href="https://play.google.com/store/apps/details?id=com.kingfishertech.sudoku">https://play.google.com/store/apps/details?id=com.kingfisher...</a><p>Here's a screenshot of the main app page: <a href="https://imgur.com/a/FbCf2IJ" rel="nofollow">https://imgur.com/a/FbCf2IJ</a><p>Thanks for taking a look and happy solving!
