Let's Encrypt will issue 64-day certificates by default from 10 February 2027, flips its staging environment on 14 October 2026, and drops to 45 days with seven-hour authorization reuse in 2028.

GitHub's $120k Copilot Rust port: budget your own rewrite

Terraform to Bicep Migration on Azure: A Field Guide

Moving Azure infrastructure from Terraform to Bicep is less about converting HCL files and more about replacing a state-file workflow with a deployment-based one. This field guide covers when migration pays off, inventorying tfstate, incremental coexistence patterns, the decompile tooling that exists, deployment stacks as the lifecycle answer, and the what-if validation and rollback discipline that keeps the cutover safe.
