Show HN: PMG, open source package firewallhttps://github.com/safedep/pmgHi HNI am the founder of SafeDep. We have been detecting malicious packages for a while. Coming from DevSecOps background, I always considered malicious package detection & protection to be a build stage problem. But I was wrong since the S1ngularity and early Shai-Hulud days.In 2026, we pretty much started worrying more about our own dev machines than CI/CD environment. Depending only on threat intelligence data (OSV / SafeDep / Socket / any other source) to protect our own dev machines did not feel right. We wanted to build a multi-layered protection that can get 100% visibility of OSS packages coming in, and can protect against known and “hopefully” unknown threats. That’s how Package Manager Guard (PMG) started. Core idea was simple:- Start a local proxy (localhost)- Make sure supported package managers like npm, pnpm, pip etc. goes through it- Use threat intelligence data to fail fast on known malicious packages- Apply policies like dependency cooldown as additional guardrails- AdJul 21, 2026 4:58 PM

Show HN: An MCP server that turns async-work practices into toolshttps://github.com/open-and-async/mcpMore than a decade ago, I adopted the self-imposed rule, if I answer a question more than once, the third time I need to be able to answer with a URL. Today, I published one very large URL - a book distilling what I learned from helping people work remotely at GitHub, and I wanted to rethink my rule for the age of AI.What if, instead of a URL, I could create an interactive experience that could tailor the guidance to your particular situation?What I ended up building was an Open and Async Advisor MCP server. To install (in claude or any other AI):> claude mcp add open-async -- npx -y @open-and-async/mcpTransparently, yes, it's from a book I wrote which launched today, but the MCP server is open source and free to use. No purchase required. It knows the key principles of the book, and has specialized tools like `draft_decision_doc`, `convert_meeting_to_async`, `score_status_update`, `triage_sync_vs_async`.This is an experiment for me, and I'm genuinely curious if it's helpful for othersJul 21, 2026 4:06 PM

Poland Boosts Its Contribution to Europe’s IRIS2 Constellation to €656Mhttps://europeanspaceflight.com/poland-boosts-its-contribution-to-europes-iris2-constellation-to-e656m/Poland has formalised its participation in Europe’s IRIS2 secure communications constellation and agreed to increase its contribution by more than €150 million. The additional funding will double Poland’s contribution to the programme’s space segment to 12 satellites, comprising six in medium Earth orbit (MEO) and six in low Earth orbit (LEO). The agreement, signed on […] The post Poland Boosts Its Contribution to Europe’s IRIS2 Constellation to €656M appeared first on European Spaceflight.Jul 21, 2026 3:40 PM

Show HN: A chess game you play with Claude as your wing-bot in the CLIhttps://github.com/goawaygeek/ground-controlHey HN!Wanted to show off a thing I built in case it interests anyone.I wanted to build a game you play inside the claude code CLI and back when they launched the channels feature I started investigating ways to use that to do so. I started with a multiplayer comedy battle game where you would collaborate with Claude to write jokes based on a theme in a timeframe and then post them to an audience and compete against other folks (with the audience voting for the funniest joke), it was OK but I didn't have anyone to really test it with so I moved on. My son has been learning chess so instead I tweaked it to let you play chess with Claude suggesting three possible move options for you to choose from and submit as your move (you choose what you actually want to do not Claude). It was much more fun and allowed me to actually learn a thing or two about chess (my chess isn't great, it didn't need to do much to help me learn but I could go back and forth with it on why a certain move was betteJul 20, 2026 11:40 PM
