💥 Check out this must-read post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: The homeownership rate in the United States is reported to be 65 percent. But this commonly cited data point on homeownership is actually the owner-occupancy rate, which tells us how many housing units are occupied by an owner. While owner occupancy is an interesting measure, it doesn’t tell us how many people own their home. As an alternative to better reflect the share of adults who are homeowners, we offer the homeowners-to-population ratio, or HPOP, a measure that lends a more nuanced view for…

✨ Check out this insightful post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: For some reason, during TacoSprint 2026 I decided to see if we could tackle relocatable binaries in Nix. I enjoy these lofty goals to push Nix and the surrounding ecosystem forward. I am bold if not stupid. I left the last earlier post with one potential idea of how to get there: We could patch the Linux kernel so that $ORIGIN is supported in PT_INTERP and the shebang. I waded through the complexity of sending patches over email (turns out I actually enjoy this…

🚀 Discover this must-read post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: 20th July 2026 I keep hearing anecdotes from people who used coding agents to reverse-engineer and automate devices in their homes. I think this is an interesting illustration of the impact of the reduced cost of writing code. Prior to agents, it was entirely possible to reverse-engineer home devices. The problem was the ROI - was it really worth all of that effort? More importantly, any experienced programmer knows that undocumented, unstable APIs like that may well change or break in the future. Is that…

Opaque, Interoperable Passkey Records (and a Go API)

0 CommentsEntertainment

💥 Read this insightful post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: Passkeys are the most important thing happening in information security right now because they are the only principled solution to the overwhelming effectiveness of phishing attacks. Just like memory safety is the only principled solution to memory corruption attacks. Unfortunately, implementing them on the server side can appear more complex than using password hashes. Part of this is unavoidable because passkeys require interaction with the browser to get their phishing resistance properties. Part of it, however, could be abstracted away a little more effectively by…
