My name is Adrian. I&#x27;m a Software Engineer and I spent 6 years developing a perimeter-based geofence-based social media app.<p>What it does:<p>- Allows you to load a custom perimeter anywhere on the geographic map (180° E and W longitude and 90° N and S latitude), to cover area any area of interest<p>- Chat rooms get loaded within the perimeter<p>- You can chat with people within the perimeter<p>I developed a mobile app that uses an advanced geofence-based networking system from 2013 to 2019. My goal was to connect uses within polygon geofences anywhere in the world. The app is capable of loading millions of polygon geofences anywhere in the world.<p><a href="https:&#x2F;&#x2F;enterpriseandroidfoundation.com&#x2F;assets&#x2F;images&#x2F;other&#x2F;manhattan-polygon-geofences.png" rel="nofollow">https:&#x2F;&#x2F;enterpriseandroidfoundation.com&#x2F;assets&#x2F;images&#x2F;other&#x2F;...</a><p>But people didn&#x27;t really have a need for this. So after failing, I spent the next 6 years trying to ideas to use FencedIn for. I tried a location-based video app and a place-based app that had multiple features. Nothing worked, but now I&#x27;m almost finished developing ChatLocal, an app that allows you to load a perimeter anywhere on the geographic map, which loads chat rooms.<p>The tech stack is 100% Java (low-level mostly). I have a backend, commons library and an Android app. Java was the natural choice back in 2013. However, I still wouldn&#x27;t choose anything else today. Java is the best for long-term large-scale projects. (I&#x27;m also using WildFly. PostgreSQL and a Linux server.)<p>This app is still not fully finished, but I think the impact on society might be tremendous.<p>The previous app to ChatLocal, LocalVideo, is fully up on the Google Play store and can be tested. It has 88% of the features of ChatLocal, including especially the perimeter-based loading system.<p>The feedback I&#x27;m mostly looking for is new ideas and concepts to add to this location-based social media app. And how strong of a value proposition does the app have for society.

Hi HN,<p>I’ve been working on Rikta, a backend framework for Node.js designed to make building scalable TypeScript applications more intuitive and modular.<p>After working with various Node frameworks, I felt there was a need for something that strictly enforces modularity and provides powerful out-of-the-box integrations without the &quot;magic&quot; that often makes debugging difficult.<p>What is Rikta? Rikta is a collection of packages designed to work together seamlessly. It’s built around a core that handles the application lifecycle and dependency injection, allowing you to plug in exactly what you need.<p>Key Features:<p>Zero-Config Autowiring No imports: [], exports: [], or providers: [] arrays. Just decorate your class, and it works.<p>Fastify Powered: Built on top of Fastify for maximum performance and low overhead. Rikta is 32% faster than NestJS on average.<p>Built-in TypeScript Support: Developed in TS for TS. You get full type safety across your entire backend stack.<p>First-class Integrations: Native support for TypeORM (database) and Swagger (automatic API documentation) via @riktajs&#x2F;typeorm and @riktajs&#x2F;swagger.<p>Developer Experience: A dedicated CLI (@riktajs&#x2F;cli) to scaffold components and manage the project structure efficiently.<p>Lightweight Core: The core remains lean; you only add the features your specific application requires.<p>Why I&#x27;m building this: The goal of Rikta is to bridge the gap between &quot;unstructured&quot; Express apps and &quot;overly complex&quot; enterprise frameworks. I wanted a developer experience that feels fast but results in a codebase that a team can maintain for years.<p>Looking for Feedback &amp; Collaborators: The project is currently in its early stages, and I’m looking for the HN community to help shape its direction. I’d love to hear your thoughts on:<p>The modularity pattern and Dependency Injection implementation.<p>The integration of Swagger&#x2F;OpenAPI as a default.<p>What&#x27;s missing in your current Node.js backend workflow that Rikta could solve?<p>Documentation is available at rikta.dev. I&#x27;m looking forward to your critiques and suggestions!

Remotedays helps companies maintain compliance with EU cross-border remote work regulations. When employees work remotely across borders (France, Belgium, Germany, Luxembourg), exceeding specific thresholds triggers social security and tax liability shifts for both employees and employers.<p>Thresholds:<p>France&#x2F;Belgium: 34 days&#x2F;year Germany: 183 days&#x2F;year<p>Most companies track this manually or not at all, creating audit and penalty risk.<p>Key Features<p>For Employees:<p>One-click daily declarations via automated email prompts with real-time threshold tracking<p>For HR&#x2F;Compliance:<p>Real-time compliance dashboard with alerts across the entire workforce<p>Complete audit trail for regulatory inspections<p>Links<p>Live: <a href="https:&#x2F;&#x2F;remotedays.app" rel="nofollow">https:&#x2F;&#x2F;remotedays.app</a><p>Demo: <a href="https:&#x2F;&#x2F;demo.remotedays.app" rel="nofollow">https:&#x2F;&#x2F;demo.remotedays.app</a><p>Built with security and GDPR compliance as core requirements. Currently seeking feedback and open to customization or developing similar compliance solutions for specific organizational needs.<p>Questions and feedback welcome.

If you or your organization are developing projects that advance amateur radio or digital communications, now’s a great time to apply for ARDC grant funding, with our next application deadline on February 1, 2026.<p>ARDC’s priority areas for funding reflect our broader vision and strategy for supporting experimentation, education, and open technology within the amateur radio and digital communications communities. We’re especially interested in projects that align with these three areas:<p>Research &amp; Development (R&amp;D): open hardware and software systems that enable learning and experimentation (e.g. SDRs, open codec technologies, new modulation techniques).<p>Space-Based Communications: projects that create or expand access to satellite communications for amateur radio (AR) and digital communications (DC), engaging communities in wireless experimentation (e.g. GEO or HEO programs, repurposed commercial satellites, space-based tools for learning).<p>Open Source Education: scalable, open educational materials and hands-on projects that make AR and DC more accessible, especially for new learners and clubs (e.g. curricula, videos).<p>While we welcome proposals across the full range of AR and DC, projects that align with these areas remain a priority in our grantmaking decisions.<p>Learn more about these priority areas at https:&#x2F;&#x2F;www.ardc.net&#x2F;apply&#x2F;priority-areas-for-funding&#x2F;, and find information on eligibility and how to apply at https:&#x2F;&#x2F;www.ardc.net&#x2F;apply&#x2F;.
