Show HN: Deterministic security solution for AI agents – OpenClaw and 2 more https://ift.tt/UH9dJ5f

Show HN: Deterministic security solution for AI agents – OpenClaw and 2 more I wanted to share a solution that I made initially for myself for OpenClaw, that helps control what your ai agents can reach when you let it do stuff without impacting its power, I hope it's useful to you. Basically the solution lets you experiment freely with your agent within safe boundaries. It's deterministic on purpose (doesn't include any Al layer) which means the solution follows clear and already defined rules, to maximize safety/security and predictability. Rules are heavily tested on detecting prompt injection attempts and other security cases (explained in detail in the docs). Everything is local and lives on your computer including the docs site. It gives you a control panel to monitor and control boundaries. When boundaries are about to get crossed you receive an approval request which lets you see what your openclaw was trying to do. It also (currently) supports Tailscale, so you can connect your Tailscale IP address and receive everything on your phone and you can also chat normally, approve or deny requests. It lets access the control panel via your tailscale IP address (a private one is recommended) from anywhere. Currently only Telegram Channel is supported. Only supports linux os for now and Opencode Claude Code & OpenClaw runners. The things you need to get started are explained in the readme, also include quick demo/showcase images so you can see how it looks. I'll be happy to hear feedback from you guys, especially having it tested against prompt injections to see how it handles it, don't hesitate to open a ticket on the GitHub for any issue that you found, I'll do my best to fix them.

Show HN: I fixed FFmpeg's subtitle conversion (the bug from 2014) https://ift.tt/CwTYN29

Show HN: I fixed FFmpeg's subtitle conversion (the bug from 2014) FFmpeg converts everything except subtitles across format boundaries. SRT to Blu-ray PGS? "Subtitle encoding currently only possible from text to text or bitmap to bitmap." Ticket #3819, filed 2014. I built this with Claude Code over a few weeks. Claude wrote most of the encoder, found an integer overflow in the decoder buffer tracking, and ran review from five angles. I read the Panasonic and Sony patents, made the architectural calls, and told it when it was wrong about the spec. We argued about whether DTS computation belongs in the muxer. (It does, and also in fftools. We did both.) Animation is an interesting problem. Advanced SubStation Alpha fades have to survive conversion to Blu-ray's PGS format. The encoder watches pixel changes between frames and classifies them: palette shift or full redraw. Fades become palette-only updates, no bitmap retransmission. Overlapping subtitles with different end times took four rewrites and an event lookahead window. I'd like to maintain this properly and get the patches upstream eventually. If you hit a bug or have a subtitle workflow that doesn't work, open an issue. I'm dead curious what people do with this, but i have some plans for translation related plugins building on the OCR work. Six iterations. 23 patches. libass and Tesseract were already in FFmpeg's filter library. I wired them into the main pipeline the same way sub2video works. Text to bitmap, bitmap to text, 114 OCR languages, RGBA-to-GIF. The development page has the history. Pre-built for 6 platforms, no dependencies: https://connollydavid.github.io/pgs-release/ https://connollydavid.github.io/pgs-release/ March 17, 2026 at 01:39PM
