And who’s surprised? It was long overdue, and puts into plain language a simple but vital truth: space is now a theatre of power. With Russia and China long having treated orbit as contested territory, and the United States preparing daily for […] The post What Germany got right (and wrong) in its first ever space strategy appeared first on SpaceNews.Dec 17, 2025 2:00 PM

Show HN: I built a fast RSS reader in Zighttps://github.com/superstarryeyes/hysWell, I certainly tried. I had to, because it has a certain quirk inspired by "digital minimalism."The quirk is that it only allows you to fetch new articles once per day (or X days).Why? Let me explain...I want my internet content to be like a boring newspaper. You get it in the morning, and you read the whole thing while sipping your morning coffee, and then you're done! No more new information for today. No pings, no alerts, peace, quiet, zen, etc.But with that, I needed it to be able to fetch all articles from my hundreds of feeds in one sitting. This is where Zig and curl optimisations come in. I tried to do all the tricks in the book. If I missed something, let me know!First off, I'm using curl multi for the network layer. The cool thing is it automatically does HTTP/2 multiplexing, which means if your feeds are hosted on the same CDN it reuses the same connection. I've got it configured to handle 50 connections total with up to 6 per host, which seems to be the sweet spot beforeDec 16, 2025 7:55 PM

Show HN: Detail, a Bug Finderhttps://detail.dev/Hi HN, tl;dr we built a bug finder that's working really well, especially for app backends. Try it out and send us your thoughts!Long story below.--------------------------We originally set out to work on technical debt. We had all seen codebases with a lot of debt, so we had personal grudges about the problem, and AI seemed to be making it a lot worse.Tech debt also seemed like a great problem for AI because: 1) a small portion of the work is thinky and strategic, and then the bulk of the execution is pretty mechanical, and 2) when you're solving technical debt, you're usually trying to preserve existing behavior, just change the implementation. That means you can treat it as a closed-loop problem if you figure out good ways to detect unintended behavior changes due to a code change. And we know how to do that – that's what tests are for!So we started with writing tests. Tests create the guardrails that make future code changes safer. Our thinking was: if we can test well enough, we cDec 9, 2025 5:35 PM

In earlier work these islands were identified mainly in neutron rich isotopes such as beryllium 12 with N = 8, magnesium 32 with N = 20, and chromium 64 with N = 40, all distant fDec 9, 2025 4:08 AM

The dead star is a type of white dwarf that exerts a powerful magnetic field as it pulls material from the larger star into a swirling, accreting disk.

It was a miracle of usability—and architecturally broken from day one.Press Ctrl+C and the entire payload—bytes, formatting, metadata, embedded objects—dumps into a system buffer that any application can read. No auth. No logging. No revocation.The clipboard is a broadcast channel disguised as a convenience.The catastrophe: The clipboard is now the #1 data exfiltration vector in enterprise. 77% of knowledge workers paste corporate data into AI tools. Every paste bypasses your CASB, EDR, SIEM, and DLP. Your security stack guards the front door while users walk data out the side.The waste: 40 billion copy operations/day × ~100KB average = 4 exabytes of daily churn. RAM pressure, cloud sync, VM duplication—all unnecessary. Annualized: 83B kWh, 33M tons CO₂, $10B in energy costs.

Show HN: Memory System Hitting 80.1% Accuracy on LoCoMo (Built in 4.5 Months)https://github.com/vac-architector/VAC-Memory-SystemI’ve been working on an independent memory-retrieval architecture for agent systems. I don’t have a CS background — previously worked climbing cell towers and doing handyman jobs — but I spent the last 4.5 months building a hybrid memory system from scratch.The system combines FAISS, BM25, and a symbolic ranking layer (MCA). Answers are generated with GPT-4o-mini at temperature 0. The focus is determinism, transparency, and reproducibility rather than model size.On the official LoCoMo benchmark (1,540 questions), the system reaches 80.1% average accuracy. To my knowledge, that’s above the publicly reported results for existing agent-memory stacks using small models.Latency is ~2.5 seconds, and cost is ~$0.10 per 1M tokens. Memory is fully isolated and local, which makes it usable for offline or enterprise applications.Repository (code + full reproducible benchmarking): https://github.com/vac-architector/VAC-Memory-SystemHappy to answer technical questions, discuss the architecture, or Nov 25, 2025 5:25 PM

That meant solving for GPS drift, multi-zone mappNov 13, 2025 12:23 PM
