Show HN: We made an open-source personalization engine
Hey, HN! You probably know that the ordering of products on Amazon, posts in FB, and search results in Google is personalized for each visitor, as it directly affects conversion, click rate and engagement. But not everyone can afford to hire an army of PhDs to squeeze every penny out of the ranking, and not everyone agrees on the current (im)balance between privacy and profits.<p>So we built Metarank, an open-source and privacy-focused personalization engine. It can rerank in real-time any type of content, using only the data you allow, and optimize metrics you define.<p>We made a lot of proprietary DIY services for personalization in e-commerce in our past careers and heard so many complaints from other companies also struggling to implement personalization. It’s often considered "too risky" to spend 6+ months on an in-house moonshot project to reinvent the wheel without an experienced team and no existing open-source tools. Like other people in the industry, we were tired of building everything from the bottom up each time we approached personalization - it should be easy not only for Amazon to do such magical ML tricks, but for everyone else.<p>A small demo of the tool with personalized recommendations: <a href="https://demo.metarank.ai" rel="nofollow">https://demo.metarank.ai</a><p>A blog post on how this demo was made: <a href="https://medium.com/metarank/personalizing-recommendations-with-metarank-f2644112536b" rel="nofollow">https://medium.com/metarank/personalizing-recommendations-wi...</a><p>The project itself: <a href="https://github.com/metarank/metarank" rel="nofollow">https://github.com/metarank/metarank</a>

Show HN: BoxyHQ – open-source alternative to Auth0/WorkOS
Hi HN, we are Deepak and Sama, co-founders of BoxyHQ (<a href="https://boxyhq.com/" rel="nofollow">https://boxyhq.com/</a>). BoxyHQ provides an open-source platform for developers to quickly integrate enterprise features into their software solutions. These include SAML Single Sign-On (SSO), Audit logs, with more to come :)<p>Every B2B startup faces a common challenge when it comes to selling into the Enterprise; they need to allocate time and resources to support all the requirements to make their offering enterprise-grade. Supporting these requirements is a significant undertaking for the engineering team, especially since they already have their hands full with the core product. We experienced this problem ourselves and that is why we built BoxyHQ, a platform to integrate enterprise features in any SaaS app with just a few lines of code.<p>The main difference with Auth0 and WorkOS is that BoxyHQ is being built on an open source ethos. Our focus is to be a developer-first security platform, putting developers at the centre of our holistic approach and help them close the gap between compliance and security.<p>Please let me know if you have any questions, you can also reach out to me at deepak@boxyhq.com

Show HN: A photo sharing app that isn't trying to be a TikTok clone
We launched Pidgeon a few weeks ago, and since then we've had a chance to fix a lot of bugs and upgrade the usability a significant amount.<p>The app is made just for photo sharing. No videos, no NFTs, just pictures, comments, and chats. Each post is ranked like on reddit - a combination of the user upvote/downvotes and the amount of time passed since the post's creation.<p>We're also trying to stay away from ads, and instead adopt a freemium model. The main reason for this is because people are a lot more concerned with privacy these days, and if we aren't serving ads, then the user knows that we don't have an incentive to steal their data.<p>There's already a small community of about 1500 on the app, with a lot of them being professional photographers. So the photos going up look really nice (at least in my opinion). But we don't just want to be a community of people who consider themselves photographers - that's a mistake that other platforms like Flickr and VSCO make. To become widespread, you need to make your platform simple to use for the casual person; only catering to professionals will necessarily keep your community smaller than it otherwise would be.<p>Users have been asking for a desktop client, and while we don't have one yet, we do plan to add it - and it won't take us as long as IG to do it, and neither will it be an afterthought where the UX is intentionally made poor so that you're pushed to use the app instead. But we want to polish the mobile app first before we get there, and there's still a lot of work to do since it's super early days.<p>If you want to try it out, here's the link:<p>https://play.google.com/store/apps/details?id=app.pidgeon.pidgeon<p>https://apps.apple.com/us/app/pidgeon-simple-photo-sharing/id1605784768<p>And please do provide any feedback you have on the app! It really does help us make it better.
Show HN: I built a platform for projects to find maintainers
A few days ago, someone I follow asked the community for help maintaining his side-project, 512kb.club. This got me thinking.<p>There are loads of maintainers out there feeling burnt out, but they can't abandon their project since people are depending on the project to be maintained.<p>In an effort to combat this, I built a website that lists projects looking for new maintainers. It's still quite empty and has some rough edges. Any feedback is very welcome!

Show HN: Open-Source 3D Location-Based Wireless Mesh Network
I've decided to open source the project I've been working on called Hyperspace. Hyperspace is a suite of software implementing a wireless mesh network for IoT devices. My main requirements are listed on my repo but I'll copy them here.<p>1. The mesh shall enable nodes to route packets amongst themselves.
2. The mesh shall allow nodes with limited power to participate in routing packets.
3. The mesh shall be IPv6 based.
4. The mesh shall be local. I.E. not require connection to a remote server.
5. The mesh should provide 3D location to nodes in the network.<p>Nodes use the Decawave DW1000 UWB radio to transmit and receive data, and to measure distances to other nodes. Location can be determined with enough distance measurements (see the documentation for more details). The implementation is pretty primitive at the moment. The border router server and the iOS app are super basic and have very little in terms of actual functionality, but the core ideas are there.<p>I'm not happy with the state of smart home devices. I don't like it when a manufacturer shuts down a key server and bricks a bunch of devices. I don't like it when devices don't interoperate. Therefore, I've decided to open source this project in the hopes that it gains traction and that we can work on creating better IoT devices together.
