#854I've been hacking on gaffer (https://gaffer.sh) as a way to learn and explore agentic development. It's been fun and I've even picked up a couple customers.

#855An SVG diagram generator to substitute GraphViz in pure Rust:
Solves some problems that were hard to work around with GraphViz, e.g. default and customisable styling, light and dark mode, stable / predictable layout.

#856https://muffinman-io.itch.io/spacedeck-x I'm still obsessed with making my game, which you can try it at the link above (it is desktop only). This is my first "real" game, and it has been incredibly fun and rewarding. I've been working on it in the evenings for about 4 or 5 months. It is a very ambitious mix of genres - shoot-em-up and deck-building. A lot of people said that those are genres that shouldn't be combin…
Love it! I was instantly hooked and its a lot of fun to play. And it's so smooth and easy to pick up!

#857Four months ago, someone at AWS asked me how Bedrock prevents LLMs from seeing customer data.Casual office conversation. Nothing serious. But it turned into a real discussion AWS's entire business is built on data protection, and here were all these giants calling AI agents the next big thing. Agents that, by default, see everything.I said AWS hasn't built that layer yet. But they will.That gap became astra.
Your agent gets tokens instead of real data. It reasons, decides, acts real values only resolve at execution. PHI, PCI, PII never touch the model context. Two lines of code, works with whatever you're already running.codeastra.dev That's what i am working on , did some test but need more customers review on that.

#858My friend and I are building Rover, a search engine for petabytes of raw logs in Azure: https://roverhq.io/ The core idea is to strip away the "indexing tax" that usually makes large-scale logging so expensive. Instead of moving massive amounts of data to heavy compute nodes, we’ve designed the engine to surgically fetch only the specific bytes needed to answer a query directly from storage.
We’ve spent a lot of time squeezing every bit of efficiency out of the hardware. By shifting the heavy lifting from memory-hungry string parsing to hardware-accelerated bitwise math, we can scan 1TB of data in about 1.2s for roughly $0.01. It’s been a fun challenge to see how far we can push the physics of the network and CPU to make searching massive amounts of raw data feel instantaneous.
If you’re dealing with similar scaling headaches and want to chat about it, my email is dhruv [at] roverhq.io or you can find more at https://roverhq.io/.

#859I’m building https://runprom.pt. I’ve been enjoying building it so far and it’s amazing to see that there’s people interested in paying for it!
I’ve always had a pet peeve that there’s no a good way to run prompts on a schedule…
I’m trying to polish it up more for a bigger launch in a couple of weeks
