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!

Show HN: Stratoshark, a sibling application to Wireshark
Hi all, I'm excited to announce Stratoshark, a sibling application to Wireshark that lets you capture and analyze process activity (system calls) and log messages in the same way that Wireshark lets you capture and analyze network packets. If you would like to try it out you can download installers for Windows and macOS and source code for all platforms at https://stratoshark.org.<p>AMA: I'm the goofball whose name is at the top of the "About" box in both applications, and I'll be happy to answer any questions you might have.

Show HN: Pica – Rust-based agentic AI infrastructure (open-source)
Hi HN,<p>Founder here. We built Pica, an open-source platform in Rust to enable agentic AI with three main focus areas:<p>- Access to APIs and tools: Universal SDKs that let AI agents use thousands of external actions without blowing up your context window.
- Visibility and traceability: Full audit logs of every decision/action to ensure transparency and accountability.
- Alignment with human intentions: Seamless guardrails for autonomous tasks; e.g., restricting certain email actions to human approval.<p>Why this matters: As autonomy in AI grows, we need robust solutions for trust and oversight. Pica aims to empower developers with the building blocks for safe and capable agentic systems.<p>We’d love your feedback—check it out: <a href="https://hellopica.com/" rel="nofollow">https://hellopica.com/</a><p>If you find our project useful, consider giving us a on GitHub! It means the world to us and helps others discover our work. <a href="https://github.com/picahq/pica">https://github.com/picahq/pica</a>

Show HN: Printercow – Turn any thermal printer into an API endpoint
I've always been fascinated by thermal printers – there's something magical about seeing text and images materialize on paper in seconds. But I found that working with them programmatically was always a pain. You either had to deal with ancient printer protocols or use clunky vendor-specific SDKs.
So I built Printercow (<a href="https://printercow.com" rel="nofollow">https://printercow.com</a>) – it turns any thermal printer into an HTTP endpoint with just one command.<p>Technical details:
- Supports any ESC/POS compatible printer (Epson, Star Micronics, etc.)
- Handles paper widths from 58mm to 120mm
- Automatic image dithering and scaling
- Built-in failover protection for high-volume scenarios<p>Don't have a printer yet but want to try it out? I've got you covered! When you sign-up you get 300 free prints and you can watch your creations come to life on my printer via Twitch live stream (<a href="https://twitch.tv/printercow" rel="nofollow">https://twitch.tv/printercow</a>). Perfect for testing your integration before committing to hardware.<p>I'm particularly excited about the AI integration possibilities. Instead of yet another chat interface, you can have AI generate content that exists in the physical world – artwork, poems, todo lists, custom receipts, etc.<p>Would love to hear your thoughts, feature requests, or creative use cases you can think of! Also happy to answer any technical questions about the implementation.
