- Domain Registration: From ICANN to Your Browser How domains move from ICANN through registries and registrars — the three-tier model, EPP, lifecycle states, and what happens when a domain drops.
- Multi-Agent Coordination Without an LLM A deterministic coordinator for parallel AI agents — goals, budgets, feedback loops, and redirect signals without LLM judgment in the control plane.
- TLS Fingerprinting with curl_cffi How curl_cffi impersonates browser TLS and HTTP/2 fingerprints in Python — what it handles automatically and the one header you still need to set.
- AIMD Rate Limiting for API Clients TCP congestion control applied to API rate limiting — additive increase on success, multiplicative decrease on errors. Finds the limit automatically.
- WHOIS Is Dead, Long Live RDAP ICANN sunsetted WHOIS in January 2025. RDAP replaced it — structured JSON over HTTPS instead of plaintext over TCP. Here's what changed and why it matters.
Dead internet theory? Working as designed.
