IPv6 crosses the 50% line - Google’s stats show 50% of connections to Google services using IPv6, while APNIC estimates lower global capability due to different sampling and weighting—IPv6 adoption, NAT, two-protocol Internet keywords. CORS myths and localhost attacks - A security write-up revisits the Zoom localhost server incident to show how misunderstanding CORS leads to cross-site request risks—CORS, localhost REST API, Access-Control-Allow-Origin, CSP keywords. MicroVMs inside Proxmox VE - pve-microvm adds QEMU microvm guests to Proxmox, aiming for container-like boot speed with VM isolation—KVM, QEMU microvm, fast boot, homelab infrastructure keywords. CPU SIMD tricks meet reality - meshoptimizer experiments with AVX-512 masks and GFNI for zigzag decoding, showing how compilers and microarchitecture can erase theoretical wins—AVX-512, SIMD, Zen 4, performance tuning keywords. Old OS paths and UI decisions - macOS still translates between slashes and colons in filenames, and a Windows UI history shows how file association prompts evolved—APFS, Finder, POSIX paths, Windo… ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/the-automated-daily-hacker-news-edition-6639591/episodes/ios-fingerprinting-with-public-apis-ipv6-crosses-the-50-line-hacker-news-jun-21-2026/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/the-automated-daily-hacker-news-edition-6639591/ios-fingerprinting-with-public-apis-ipv6-crosses-the-50-line-hacker-news-jun-21-2026.md` — Read the agent-friendly Markdown representation of this episode resource.
