Show HN: Skip – Build native iOS and Android apps from a single Swift codebase

Hello Hacker News. I'm Marc, one half of the team that created skip.tools. Skip is a tool that transpiles your SwiftUI iOS app into a Kotlin Jetpack Compose app, and enables you to use a single language to create a complete app that reaches the entire mobile marketplace.<p>What it is: Skip stands in contrast to other cross-platform development tools like Flutter, React Native, and Xamarin, in that it enables the creation of genuinely native applications for both of the dominant mobile platforms. It doesn't embed a separate engine or runtime into your app, but instead lets you use pure Swift and SwiftUI to create the iOS side of the app (as per Apple's recommended best practices for creating iOS apps), and transpiles it into a pure Kotlin and Jetpack Compose app for the Android side (which is Google's recommendation for building Android apps). So your application will use platform-native controls and will automatically have all the affordances provided by the platform vendor: animations, accessibility, and future-proof evolution alongside OS updates.<p>How it works: you build a Skip app using the same tools that you use to create a standard iOS app: Xcode, Swift, and SwiftUI. Skip augments this workflow with a Swift Package Manager plugin called "skipstone", which transpiles your Swift into Kotlin each time you build your app, and launches the Android app side-by-side with the iOS app each time you run the app. The transpilation works not just on your primary app module, but also transitively processes all your dependent SwiftPM modules, so you can break complex projects down into individually testable sub-modules containing business logic or UI code. In fact, this is how our own adaptor modules for the standard frameworks are structured: SkipFoundation adapts the Foundation framework and SkipUI adapts the SwiftUI framework, so the same familiar API can be used when building the app. And there's a GitHub ecosystem of open-source modules supporting popular frameworks, including SQLite, Firebase, Lottie, and many other common building blocks of modern apps.<p>Over the past year Skip has evolved into a fully-capable solution for creating best-in-class apps for both iOS and Android. And today we are delighted to announce the release of version 1.0, meaning that it is ready for production use.<p>We have a wealth of videos and documentation available at <a href="https://skip.tools" rel="nofollow">https://skip.tools</a>, and I'll be around to field any questions that any of you might have. Thanks in advance for taking a look!<p>Home: <a href="https://skip.tools" rel="nofollow">https://skip.tools</a><p>FAQ: <a href="https://skip.tools/docs/faq/" rel="nofollow">https://skip.tools/docs/faq/</a><p>GitHub: <a href="https://github.com/skiptools/">https://github.com/skiptools/</a>

Show HN: Ruroco – like port knocking, but better

Hey there HN!<p>ruroco (RUn RemOte COmmand) is a tool that lets you execute commands on a server by sending UDP packets (instead of knocking on ports).<p>the tool consist of 3 binaries:<p>- client -> runs on your notebook/computer and sends the UDP packets<p>- server -> receives the UDP packets and makes sure that they are valid<p>- commander -> runs the command encoded by the data of the UDP packet if it's valid<p>The commands are configured on the server side, so the client does not define what is going to be executed, it only picks from existing commands.<p>I use this tool to open up the SSH port on my server via ufw, but only for the IP address from where I'm connecting, so the SSH port appears closed for everyone else, except me.<p>This is my very first "real" rust project, so any feedback is highly appreciated :)<p>Enjoy!

Show HN: A Ghidra extension for exporting parts of a program as object files

This Ghidra extension unrelocates machine code through analysis and then synthesizes a working object file from a listing selection. It effectively turns computer programs into Lego bricks, to be torn down into pieces and reused into something new.<p>It supports the COFF and ELF object file formats, for the x86 and MIPS architectures. It has been successfully used on Linux, Windows and PlayStation executables. One user report is on a commercial video game from 2009 with a ~7 MiB Windows executable written in C++: it was delinked without its C runtime library and then relinked into a new executable at a different base address, with no visible change in functionality, as a prelude to a decompilation project.<p>Use-cases I've demonstrated on my blog include modding, making software ports, converting executable file formats, creating libraries... I've originally built this as part of a video game decompilation project ; I've been working on this over the past 2.5 years and recently it has started gaining some users besides me.

Show HN: InstantDB – A Modern Firebase

Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma.<p>Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can make it difficult to build delightful software. Could it be better?<p>We were senior and staff engineers at Facebook and Airbnb and had been thinking about this problem for years. In 2021, Stopa wrote an essay talking about how these schleps are actually database problems in disguise [1]. In 2022, Stopa wrote another essay sketching out a solution with a Firebase-like database with support for relations [2]. In the last two years we got the backing of James Tamplin (CEO of Firebase), became a team of 5 engineers, pushed almost ~2k commits, and today became open source.<p>Making a chat app in Instant is as simple as<p><pre><code> function Chat() { // 1. Read const { isLoading, error, data } = useQuery({ messages: {}, }); // 2. Write const addMessage = (message) => { transact(tx.messages[id()].update(message)); } // 3. Render! return <UI data={data} onAdd={addMessage} /> } </code></pre> Instant gives you a database you can subscribe to directly in the browser. You write relational queries in the shape of the data you want and we handle all the data fetching, permission checking, and offline caching. When you write transactions, optimistic updates and rollbacks are handled for you as well.<p>Under the hood we save data to postgres as triples and wrote a datalog engine for fetching data [3]. We don’t expect you to write datalog queries so we wrote a graphql-like query language that doesn’t require any build step.<p>Taking inspiration from Asana’s WorldStore and Figma’s LiveGraph, we tail postgres’ WAL to detect novelty and use last-write-win semantics to handle conflicts [4][5]. We also handle websocket connections and persist data to IndexDB on web and AsyncStorage for React Native, giving you multiplayer and offline mode for free.<p>This is the kind of infrastructure Linear uses to power their sync and build better features faster [6]. Instant gives you this infrastructure so you can focus on what’s important: building a great UX for your users, and doing it quickly. We have auth, permissions, and a dashboard with a suite tools for you to explore and manage your data. We also support ephemeral capabilities like presence (e.g. sharing cursors) and broadcast (e.g. live reactions) [7][8].<p>We have a free hosted solution where we don’t pause projects, we don’t limit the number of active applications, and we have no restrictions for commercial use. We can do this because our architecture doesn’t require spinning up a separate servers for each app. When you’re ready to grow, we have paid plans that scale with you. And of course you can self host both the backend and the dashboard tools on your own.<p>Give us a spin today at <a href="https://instantdb.com/tutorial">https://instantdb.com/tutorial</a> and see our code at <a href="https://github.com/instantdb/instant">https://github.com/instantdb/instant</a><p>We love feedback :)<p>[1] <a href="https://www.instantdb.com/essays/db_browser">https://www.instantdb.com/essays/db_browser</a><p>[2] <a href="https://www.instantdb.com/essays/next_firebase">https://www.instantdb.com/essays/next_firebase</a><p>[3] <a href="https://www.instantdb.com/essays/datalogjs">https://www.instantdb.com/essays/datalogjs</a><p>[4] <a href="https://asana.com/inside-asana/worldstore-distributed-caching-reactivity-part-1" rel="nofollow">https://asana.com/inside-asana/worldstore-distributed-cachin...</a><p>[5] <a href="https://www.figma.com/blog/how-figmas-multiplayer-technology-works/#syncing-object-properties" rel="nofollow">https://www.figma.com/blog/how-figmas-multiplayer-technology...</a><p>[6] <a href="https://www.youtube.com/live/WxK11RsLqp4?t=2175s" rel="nofollow">https://www.youtube.com/live/WxK11RsLqp4?t=2175s</a><p>[7] <a href="https://www.joewords.com/posts/cursors" rel="nofollow">https://www.joewords.com/posts/cursors</a><p>[8] <a href="https://www.instantdb.com/examples?#5-reactions">https://www.instantdb.com/examples?#5-reactions</a>

Show HN: Wd-40, a static webserver with automatic hot-reloads

It works by injecting a websocket script which listens for file changes. The filechanges are detected using the go fsnotify package, which in turn uses the different OS's equivalent to inotify.<p>I basically got bored with alt-tabbing and refresing when developing 'vanilla-js'. The hot-reload in the modern frameworks are very nice, so figured I'd recreate it.

Show HN: Handwriter.ttf – Handwriting Synthesis with Harfbuzz WASM

During the hype of llama.ttf months ago, I was speculating the potential of WASM shaper for even crazier purpose, one that fitter to a font shaper's duty -- to synthesize font at runtime. This project as proof-of-concept implements a synthesizer that generates and rasterizes handwriting-style font, backed by a super-lightweight RNN model (~14MiB).

Show HN: Srcbook – A TypeScript notebook for rapid prototyping

Srcbook (”source-book”) is an open-source TypeScript notebook that runs locally, powered by Node.js. It shines for rapid prototyping, code exploration, and collaborating on ideas. It’s inspired by Python’s Jupyter and Elixir’s Livebook.<p>Key features:<p>- Full npm ecosystem access<p>- AI-assisted coding (OpenAI, Anthropic, or local models), it can iterate on the cells for you with a code diff UX that you accept/reject for a given code cell, generate entire Srcbooks, fix compilation issues, etc…<p>- Exports to valid markdown for easy sharing and version control<p>Try it now: `npx srcbook start`<p>Examples Srcbooks to explore: <a href="https://hub.srcbook.com">https://hub.srcbook.com</a><p>We built this because we needed a Jupyter-like environment for TypeScript, we hope others like it as much as we do! Feedback and contributions are super appreciated.<p>(edit: formatting)
