Show HN: Basement – a GraphQL API for on-chain Ethereum data If we want better web3 experiences, developers need better tools. RPC nodes are really good at executing transactions, however they are notoriously cumbersome to set up, and reading large chunks of data is not very efficient: To show a list of transactions and receipts, nodes have to re-execute smart contract code on entire blocks. For every read call. Not great at scale. Which is why everyone is building ETLs to move data from the chain into their own database. This GraphQL API is our first step in allowing developers to spend more time on building product, rather than ETL infrastructure. https://basement.dev/ November 30, 2022 at 02:55AM

Show HN: Recycle your old Spotify playlists into new ones I wanted a way to quickly generate new Spotify playlists from my library based on some simple user inputs. There are probably a bunch of songs floating around in old playlists that you will never listen to again so the Spotify Playlist Recycling Plant is an attempt to resurrect these forgotten gems! At the heart of this tool is a simple custom algorithm that uses Spotify's 5000+ unique genres to find similar artists. It works well for my purposes but everybody uses Spotify differently so I'd love some feedback :) Built using React and the Spotify Web API. https://www.playlistrecycle.com/ November 25, 2022 at 05:07AM

We have been working on a native gui application to allow users to search any video data( mp4, mkv) or video streams (http/rtsp) using computer vision. Application is supposed to work like a video player which displays decoded frames and recognizes objects concurrently, making it an interactive experience. It works in super real-time and only expects a quad-core CPU with AVX2 instructions at minimum. Application is free to download (without any signup/account). We are only supporting WINDOWS for now [0]. Even though this is a binary application, we have ZERO telemetry/analytics builtin. User interface is limited for now, and definitely needs more work. But we are releasing it here for early feedback/bugs. We would love for you to try it out and hear your thoughts/feedback.

Show HN: Eleven – Free, open-source, Codespaces alternative with automatic HTTPS Hey HN, Eleven is the second project that I've built to learn Go. It lets you create code sandboxes, in your cloud provider account, easily. What's a "code sandbox"? Just a VM, running in your cloud provider account, with some runtimes pre-installed, your repositories cloned, a way to connect to it with your preferred editor (or via SSH) and a way to serve your apps easily via HTTP (with automatic HTTPS). You could use it as a remote development environment, to test some code or even to deploy your app. It's up to you. For example, to deploy a Node.JS app: $ eleven aws init hello-world --runtimes node@18.7.0 --repositories eleven-sh/hello-world > Success! The sandbox "hello-world" was initialized. $ ssh eleven/hello-world forever node index.js > Forever: command started. Run "forever stop" in current path to stop. $ eleven aws serve hello-world 8000 --as hello.eleven.sh > Success! The port "8000" is now reachable at: https://hello.eleven.sh $ curl https://hello.eleven.sh > Hello World Still learning Go by the way, so I'm open to any suggestions to improve. https://github.com/eleven-sh/cli November 13, 2022 at 01:01AM

Show HN: My paternity leave side project, a watercolor art generator https://news.ycombinator.com/item?id=33561232
Show HN: My paternity leave side project, a watercolor art generator Hi HN - this is a little side project I threw together while on paternity leave (primarily developed with one arm while holding a sleeping baby in the other). Some implementation details: image processing is all done with headless GIMP (running inside a Docker container) through its built-in Python API. It's _very_ slow (about 50 seconds/image), and currently it processes exactly one image at a time. The website is built with NextJS; payments are processed by Stripe. I've had the best results with pictures of houses, although certain photos of people or nature can look neat, too. (For example: https://brushify.art/s/ruYmQWk , original photo from https://en.wikipedia.org/wiki/Pillars_of_Creation .) The effect obscures the edges of the photo, so images with plenty of margin around the subject work best. Something I'd like to play around with is swapping the GIMP script for an AI-based process (maybe using something like Stable Diffusion?), with the goal of generating images that look more handmade (something like these: https://www.etsy.com/ca/search?q=watercolor+house ). I have exactly zero AI experience though, so there would be a bit of a learning curve. Would love any thoughts or critiques! https://brushify.art/?couponCode=HACKER-NEWS November 11, 2022 at 06:32AM

Show HN: Practice for Your YC Interviews with Betafi Hi folks, Betafi is a product feedback platform build around moderated user interviews and usability testing sessions. To help folks applying for the W23 batch with interviews coming up this week, we just launched a project templates feature and catered onboarding for fellow founders to practice and conduct mock YC interviews with each other. You can use Betafi's interview script feature, "instant tags," and timestamped notes to take turns annotating rough spots and practicing rapid-fire responses to questions with your cofounder(s), to try and make the most out of those 10 minutes during your real YC interview. A big part of the joy of building Betafi is getting to support other early-stage founders who wind up using our product in interesting and creative ways. This project came out of several teams applying to the W23 batch, who organically started using Betafi to help prepare for their interviews, so we thought we might as well build "first class" support for it! Do let us know what you think, keen to hear your feedback, especially given this is a slightly different use-case from what we initially designed the product for! https://www.betafi.co/yc-interview-prep November 10, 2022 at 01:00AM

Show HN: Cozo – new Graph DB with Datalog, embedded like SQLite, written in Rust Hi HN, I have been making this Cozo database since half a year ago, and now it is ready for public release. My initial motivation is that I want a graph database. Lightweight and easy to use, like SQLite. Powerful and performant, like Postgres. I found none of the existing solutions good enough. Deciding to roll my own, I need to choose a query language. I am familiar with Cypher but consider it not much of an improvement over CTE in SQL (Cypher is sometimes notationally more convenient, but not more expressive). I like Gremlin but would prefer something more declarative. Experimentations with Datomic and its clones convinced me that Datalog is the way to go. Then I need a data model. I find the property graph model (Neo4j, etc.) over-constraining, and the triple store model (Datomic, etc.) suffering from inherent performance problems. They also lack the most important property of the relational model: being an algebra. Non-algebraic models are not very composable: you may store data as property graphs or triples, but when you do a query, you always get back relations. So I decided to have relational algebra as the data model. The end result, I now present to you. Let me know what you think, good or bad, and I'll do my best to address them. This is the first time that I use Rust in a significant project, and I love the experience! https://github.com/cozodb/cozo November 8, 2022 at 04:25AM

Show HN: RxJS Insights – a toolset for RxJS visualization Hi HN! I'd like to present you the thing that I'm building - the RxJS Insights. It was primarily created as something that allows for debugging complex RxJS streams, but after showing it to a few people it turned out that it might be more helpful in learning RxJS since it can visualize the observables execution step by step. The setup is somewhat similar to the Redux Devtools' one in a sense that it requires an application level component (the proper @rxjs-insights/* packages) to instrument the RxJS and to connect with the devtools. I invite you to try it out in your app (the setup is rather easy) or on StackBlitz (all links are in the readme). Thanks! https://github.com/ksz-ksz/rxjs-insights November 7, 2022 at 01:02AM

Show HN: Stable Diffusion print-on-demand apparel Hey HN, Obviously we are experiencing a surge of stable-diffusion based apps at the moment, but I have yet to see anyone try and map the outputs onto actual physical products that can be delivered to your door. I wanted to make it easy to: - pick an artistic style - hit 'record' and speak into your phone / tablet / desktop or whatever, and describe the kind of design you want your clothing to have (since speaking is more spontaneous that typing) - swipe among a variety of mockups (t-shirts, hoodies etc.) featuring your design, and order it to your door with the click of a button The product is called 1SEWN. Fulfilment is currently achieved using a print-on-demand service called Printful ( https://www.printful.com ) that I have integrated with. If you guys would like to try it, I would love some feedback. Shipping is currently limited to outside Europe, but even if you are in Europe, your feedback about the whole UX would be much appreciated! Much love, Matt https://www.1sewn.com/ November 5, 2022 at 05:08AM

Show HN: Xata, serverless database on top of PostgreSQL and Elasticsearch https://news.ycombinator.com/item?id=33432425
Show HN: Xata, serverless database on top of PostgreSQL and Elasticsearch Hi! Xata was on HackerNews once before ( https://news.ycombinator.com/item?id=28590816 ) a bit over a year ago, when we were at the beginning of our development. We've promised we're going to do a Show HN page when we come out of Private Beta, and this just happened today. Xata is a product in the serverless database space. We know that the space is fairly crowded now, with lots of great companies started recently. We're happy to see a fresh wave of database products, that are focused more on the developer experience, rather than a race to the bottom on performance and cost. We are part of this wave, but we also think our offering is quite differentiated: - First, out of all the options out there, we're aiming to be the easiest to get started with and the easiest to use. We are cloud-only and our product feels more like a SaaS-like experience than an IaaS experience. If you've hacked together an app with data stored in Airtable or GitHub, you should try Xata next time. It's just as easy to use but has constraints, data integrity, type-safe clients, etc. - We offer functionality from multiple data stores. Today, the source of truth for the data is in PostgreSQL and we also replicate it in Elasticsearch. This means that we can offer free-text-search and aggregation functionality that goes beyond what's possible in PostgreSQL. In the future, we'll add more functionality around in-memory caching, queues, etc, so all data patterns that you need are available via a single, serverless, consistent API. This sounds complex (and it is), but the complexity is entirely on our side. Your application can just reap the benefits. - It is vertically integrated and focused on developer workflows: we provide a nice web UI, a TypeScript/JavaScript SDK, and VS Code extension, all working together with minimal friction. The TypeScript SDK is somewhat similar with Prisma, because it gives you type safety for both the parameters and the return types. However, it is different because it is a pure-TypeScript implementation, which means it is more lightweight and can run in Cloudflare Workers, Deno Deploy, etc. Some more links, if you want to dig into the details: - For examples of the API, see our API Guide: https://xata.io/docs/api-guide/insert - For technical details about the inner workings of Xata, see our fairly long How it Works guide: https://xata.io/docs/intro/how-it-works - We think this approach is new and gave it a name: Serverless Data Platform, which is explained here: https://xata.io/docs/intro/serverless-data-platfrom - For a high-level overview of the features available, see: https://xata.io/features We would really love your feedback! https://xata.io November 2, 2022 at 12:43AM
