Show HN: Trolling SMS spammers with Ollama

I've been working on a side project to generate responses to spam with various funny LLM personas, such as a millenial gym bro and a 19th century British gentleman. By request, I've made a write-up on my website which has some humorous screenshots and made the code available on Github for others to try out [0].<p>A brief outline of the system:<p>- Android app listens for incoming SMS events and forwards them over MQTT to a server running Ollama which generates responses - Conversations are whitelisted and manually assigned a persona. The LLM has access to the last N messages of the conversation for additional context.<p>[0]: <a href="https://github.com/evidlo/sms_llm">https://github.com/evidlo/sms_llm</a><p>I'm aware that replying can encourage/allow the sender to send more spam. Hopefully reporting the numbers after the conversation is a reasonable compromise.

Show HN: Lightpanda, an open-source headless browser in Zig

We’re Francis and Pierre, and we're excited to share Lightpanda (<a href="https://lightpanda.io" rel="nofollow">https://lightpanda.io</a>), an open-source headless browser we’ve been building for the past 2 years from scratch in Zig (not dependent on Chromium or Firefox). It’s a faster and lighter alternative for headless operations without any graphical rendering.<p>Why start over? We’ve worked a lot with Chrome headless at our previous company, scraping millions of web pages per day. While it’s powerful, it’s also heavy on CPU and memory usage. For scraping at scale, building AI agents, or automating websites, the overheads are high. So we asked ourselves: what if we built a browser that only did what’s absolutely necessary for headless automation?<p>Our browser is made of the following main components:<p>- an HTTP loader<p>- an HTML parser and DOM tree (based on Netsurf libs)<p>- a Javascript runtime (v8)<p>- partial web APIs support (currently DOM and XHR/Fetch)<p>- and a CDP (Chrome Debug Protocol) server to allow plug & play connection with existing scripts (Puppeteer, Playwright, etc).<p>The main idea is to avoid any graphical rendering and just work with data manipulation, which in our experience covers a wide range of headless use cases (excluding some, like screenshot generation).<p>In our current test case Lightpanda is roughly 10x faster than Chrome headless while using 10x less memory.<p>It's a work in progress, there are hundreds of Web APIs, and for now we just support some of them. It's a beta version, so expect most websites to fail or crash. The plan is to increase coverage over time.<p>We chose Zig for its seamless integration with C libs and its <i>comptime</i> feature that allow us to generate bi-directional Native to JS APIs (see our zig-js-runtime lib <a href="https://github.com/lightpanda-io/zig-js-runtime">https://github.com/lightpanda-io/zig-js-runtime</a>). And of course for its performance :)<p>As a company, our business model is based on a Managed Cloud, browser as a service. Currently, this is primarily powered by Chrome, but as we integrate more web APIs it will gradually transition to Lightpanda.<p>We would love to hear your thoughts and feedback. Where should we focus our efforts next to support your use cases?

Show HN: Open-source AI video editor

Hey HN community! I'm one of the lead devs of this project at fal.ai and we created an open source lightweight video editor powered by the latest media AI models. The main goal was to tackle some challenges when dealing with complex media handling and encoding on the browser.<p>It all started as an internal experiment but as we tackled some of the issues it was clear there could be some value sharing it with the open source community.<p>Some of the key points and tech stack details:<p>- It uses IndexedDb, so all data is local (i.e. no auth, no cloud db)<p>- Multiple AI models for video, image, music and voice-over. APIs are provided by fal.ai<p>- Built with the typical React+Next.js, Shadcn front-end<p>- Used remotion.dev for the realtime video preview (this is such a great project, without it the codebase would be twice as large)<p>- File uploads so you can bring your own media by uploadthing.com<p>- ffmpeg for encoding the final video and also some ui tricks, like the audio waveform<p>We deployed a version of it and for now it's free to use. We do plan to add some rate limiting and a bring your own API Key next, but it's open source and I'm curious about what the community will build on top of it, or derive from it. Customize your own video app and if you do, please share.<p>If you have any questions, hit me up!

Show HN: I built an active community of trans people online

A year ago I surveyed the internet and noticed there was only one popular space for trans and gender-non-conforming people to meet; Lex.<p>Lex is not well liked by its users. Its software feels heavy and it is full of cash grabs and anti-patterns. It was recently acquired and is sure to only become more hostile to its users as it turns towards profit generation.<p>With this in mind I built t4t, an alternative specially designed for not only queer people, but specifically trans people.<p>It is an extremely lightweight service. I built it with my most ideal stack: Flutter, Svelte, Supabase, Posthog.<p>It has grown in the last year to about 4,000 monthly active users. I think it could grow way beyond that this year.

Show HN: I made a service to convert WordPress blogs to Hugo

Hi Hacker News!<p>I made this project to read a WordPress export and create the markdown files for Hugo. It'll speed up the process of moving your blog over to Hugo and let you avoid a bunch of manual work.<p>It came about when I was talking to somebody who was trying to move their site over and didn't want to manually copy and reformat all their posts. They had trouble finding a tool to do it, so I wrote one.<p>I want to make sure it's useful to people before charging them, so it'll give you a download with 3 pages and 5 blog posts converted for free and without asking for any information. If you like what you see, there is a one-time charge through Stripe to convert everything.<p>I hope you find it useful, and I welcome any and all feedback on it!<p>Thanks for reading!

Show HN: NotepadJs – A cross-platform love letter to Notepad

As a native Windows user who switched to macOS a few years back, one thing I never got over was the simplicity and usefulness of the old school Notepad app. This app aims to recreate that very same experience, cross-platform and easily installable as a PWA.<p>I've been using this for personal use for around 2 years and I figured it was time to share it with the world. Criticism, issues and PRs are welcome. Thanks!
