Show HN: Capy – A Git-style platform for managing your team's secrets
Hello HN!<p>We're all spending more and more time making stuff with agents, but I've noticed that one of the things that is the most disconnected from my daily engineering workflow is dealing with secrets and credentials. It often involves a lot of click-ops, copying/pasting, and collaboration, and none of the secrets management products out there have truly scratched that itch.<p>I built Capy to solve this. It's a secrets manager whose entire frontend is a developer CLI, and I find it extremely ergonomic to use by hand. You also don't need to leave the CLI to sign up for and use it! You can install and authenticate without leaving your terminal (or agent) session.<p>It also has very powerful version management with git-like branching and conflict resolution. You can push a version manifest to source control and have collaborators pull a specific version of the secrets at any point in time.<p>The platform itself is extremely secure. It encrypts your local .env files so they can't be read directly. Upon pushing the values to the service, it encrypts them yet again with a service key. That way neither a compromised local machine nor a compromised service alone will result in a leakage.<p>BTW: Since it was released in April, I've been refining it and have evolved the focus a bit. Originally I was going for more TUI and TTY with guided wizards for doing things like deployments, rotations, and connecting services, but I realize that the real future is in making the product work EXTREMELY well with agents.<p>So the next evolution of is a more satisfying Agent ergonomic, and I have been working on something big next on that front.<p>Curious about your thoughts on the idea, execution, and would appreciate any and all feedback!

Show HN: A little physical breakout clone
Idea: How about a 5 minute game I can play in my browser and it's actually fun to play.<p>Controls: Mouse or keyboard (left/right, left alt/right alt or A/D), space and esc are pause toggle. Page up / Page Down are next or previous level (if already unlocked).<p>Cheats: Z toggles zapper, M toggles magnets.<p>Debug stuff: I, P, E keys are toggles for various stuff (E lets you change some aspects of physics engine).<p>Game is maybe playable on mobile devices, there is a menu on top right, and then click the circle to select type of control.<p>Physical engine is decoupled from refresh rate and runs at 240 Hz.<p>Fully vibe coded (deepseek, chatgpt), levels are human made with some amount of love.

Show HN: SIMD Viterbi Decoder in Rust
I wrote libcorrect in C in 2016 and wanted to revisit it in Rust. Instead of doing just a direct conversion, I went down the rabbit hole of making Rust's std::simd work for me. I ended up with a templated, generic Viterbi decoder for convolutional codes that dispatches the decode at runtime depending on which instruction sets are available. For small rates and orders, the entire decode lives in registers. Larger codes work through memory but take advantage of some acceleration structures.<p>I also spent some time building a tool to find optimal (max d_free) conv codes for a given rate and order. Of course, there are better mechanisms available today, but I'm happy to talk through anything I learned in the process.

Show HN: Simple algorithm and color space to generate diverse skin tones
Hello HN!<p>I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy.<p>I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has.<p>The methodology might be a bit shaky, but hopefully the result is as helpful for others as I have found it! There's lots of room for improvements (see the Future Work section), but I'm really happy with how it turned out.

Show HN: Make your Framework 12 sound like a creaky door
I was poking through the iio devices on my Framework the other day and turns out Framework 12s have a pretty accurate hinge angle sensor! So I made a version of LidAngleSensor (<a href="https://github.com/samhenrigold/LidAngleSensor" rel="nofollow">https://github.com/samhenrigold/LidAngleSensor</a>) but for the Framework 12 on Linux, so you can make your hinge sound rusty
