Show HN: Arctype, a cross-platform database GUI for developers and teams Hi HN! I’m Justin, founder and CEO of Arctype, and we’re very excited to share Arctype with the community. Arctype is a cross-platform GUI (soon to be open-sourced) to manage and query your databases, with built-in collaboration and visualization. It currently supports Postgres, MySQL, and SQLite, as well as newer-generation databases like ClickHouse, PlanetScale, and Yugabyte (and more coming very soon!). Think of Arctype as “phpMyAdmin meets Postman”. Most of our team grew up learning how to program using the LAMP stack and we missed the experience of interacting with our databases using phpMyAdmin. We wanted to bring back the experience of a simple app that lets you explore and query your databases, but with an updated and modernized interface. At the same time, we were heavily inspired by the ease-of-use and collaboration features of Postman. We wanted to create a super useful, collaborative app like Postman that your whole team uses for development—but for databases instead of APIs. We have a few thousand developers using Arctype today but we haven’t shared it with the HN community yet–we’re excited to hear your feedback! We also have a very active Discord community at arctype.com/discord where developers can ask questions and talk about databases/SQL. I’m sure the community has a lot of questions, so we’ve compiled a list of the most common ones we get: “Why isn’t Arctype open source yet?” It will be soon! We’ve been focusing mostly on features that users have been asking for, as well as performance, stability, and security. We’re not completely happy yet with the documentation and development experience of contributing to Arctype, but this will be a core focus for us in the coming weeks. We just want to make sure it will be very easy for the community to contribute once we publish on GitHub. “How does Arctype make money?” Arctype is free (and will be free forever) for most developers. We have a typical SaaS model for large teams based on a per-seat license as well as an enterprise version that companies can run on their own infrastructure. “Why is Arctype built using Electron?” We wanted to make it easy for anyone to use Arctype–Electron is currently the most practical solution to make it cross-platform and also accessible via a web app. Apps like VSCode and Discord have shown that it’s possible to achieve decent performance so we’re confident that over time the advantages of developing on Electron will outweigh the slight performance hit compared to native apps. “Does Arctype need an account?” You can use Arctype without an account or you can login via email or Google. Certain features such as sharing queries and dashboards with your team require an account. “Is Arctype secure / does it store credentials?” All of your credentials are stored locally, and queries are also executed locally on your machine. We do have a feature that lets you automatically share your credentials to your team, but that is strictly opt-in, and all credentials are encrypted on our backend. Additionally, we have an enterprise version that companies can run on their own infrastructure for organizations that have stringent security requirements. If you’d like to learn more, we have more info at arctype.com/security. “Does Arctype use any analytics software?” Arctype has usage-based analytics and error reporting (we use Sentry) that we use to improve the app and to help us fix bugs/crashes. However, this can be turned off. Additionally, Arctype can be used fully offline. “Why doesn’t Arctype support X database?” Email me at justin at arctype.com :) We’ll make it happen. https://arctype.com/ May 26, 2022 at 12:19AM

Show HN: WaifuXL - SOTA image upscaling neural network that runs in the browser https://ift.tt/C9KAkvu

Show HN: WaifuXL - SOTA image upscaling neural network that runs in the browser WaifuXL is our state of the art super resolution model trained on ~1,200,000 anime style images from the Danbooru2021 dataset. You can run it straight from your browser, entirely client-side, at https://waifuxl.com . Using the Onnx Runtime, we stream the weights of our ML models directly onto your device to be executed locally in WebAssembly. Doing so allows us to provide this service solely through a static webpage, no backend for model execution needed. This has the added benefit of enabling the privacy of your images--your images are not, and never will be, sent to us. Our original inspiration for this project was waifu2x ( http://waifu2x.udp.jp ). In general, our model will outperform those used on waifu2x by a significant margin, without the need for multiple models trained on various noise reduction levels. Note that while you _can_ upscale natural (real) images, the model was only trained on anime style drawings, so don’t expect good results. It does work quite well on non-anime graphic art, however.

Show HN: My free course for learning Imba https://ift.tt/uJSlvMH

Show HN: My free course for learning Imba Today I launched an Imba course for Scrimba.com. Imba is an amazing language for building web applications, that deserves more attention. Watch my announcement video: https://www.youtube.com/watch?v=CDSIsvZJhow Take the course (it's free): https://ift.tt/qAPS6aG Some context: I fell in love with the Imba programming language a couple years ago and quit my job to spend all my time building projects with Imba. The first one being TaskTXT ( https://www.tasktxt.com ), a plaintext notepad with built-in timers. It's full of UI details that were a joy to build with Imba. Trying to build things like this with React in the past honestly made me feel dumb. Imba ( https://www.imba.io ) is a language that compiles to Javascript, like TypeScript or JSX. Imba's syntax diverges much more from Javascript, looking more like Python or Ruby. It's compatible with Javascript and Typescript and NPM modules. It also has fantastic VSCode tooling and even supports TypeScript types. I like Imba syntax better than JS, but the real selling point is the built-in features for building web UI. Imba has first-class support for html tags, css styles, and custom web components. Those are all parts of the language. For me, Imba has replaced Javascript, HTML, CSS and React. Imba's "Memoized DOM" model for updating the UI is an order of magnitude faster than virtual DOM approaches. This allows for simple state management, because you can pretty much re-render the whole UI whenever you want and Imba manages to do that very efficiently. There's an older article about this here ( https://ift.tt/FEKd6ux... ) if you want to dig into the technical details. People often ask for examples of things made with Imba, and the most prominent one is the learn-to-code site, Scrimba.com and its interactive editor. Scrimba was was built by Sindre (creator of Imba) and the Scrimba team. The fact that Scrimba's editor was made with Imba grabbed my attention when I first learned about the language. It's one of the most impressive web applications I've ever seen. Sindre originally built Scrimba to share Imba, but until now there's not been a real Imba course on Scrimba! So, I'm pleased to be fixing that today. I know Imba looks strange to a lot of people. Imba programmers are used to people looking at it and declaring it to be stupid and wrong. An open mind is required. Imba doesn't have to be for everyone, but for a certain type of developer who values design, and wants to build expressive UI quickly, it's pure magic. https://ift.tt/6AOz47g May 24, 2022 at 08:51PM

Show HN: Tetra – A full stack component framework for Django using Alpine.js https://ift.tt/Mjb1DIT

Show HN: Tetra – A full stack component framework for Django using Alpine.js Hi HN, I have been working on Tetra for the last few months and feel it’s now time to put it out there and get some feedback. Please take a look. There are a few fully functional examples on the homepage: https://ift.tt/RxgkONz Tetra is a full stack component framework for Django built on top of Alpine.js. It is heavily inspired by frameworks such as Laravel Livewire and Phoenix Liveview, enabling you to create server rendered components that respond to user interactions reactively. However, it builds on the concept by allowing you to build “hybrid” components that also have full JavaScript capabilities using Alpine.js. It also builds on the trend of bringing the different parts of a component (Python, HTML, CSS, JavaScript) into closer proximity, by keeping all related parts in the same file. It uses esbuild to bundle your JavaScript and CSS, whilst also creating source maps, making it possible to trace errors back to the original Python source files. In terms of future plans, I’m aiming for a v1 release this summer - there is still quite a long to-do list! I have been working on this in my spare time so far, but hope to find the opportunity to work on it full time. I think there is a gap in the current Python framework ecosystem, and I believe, that what I have designed in Tetra plugs that gap. I hope to build this into a significant contribution to the community. Finally, the docs are here: https://ift.tt/AWzrL3Q https://ift.tt/RxgkONz May 24, 2022 at 06:38PM
