A personal blog-style newsletter from an IT professional covering networking, security, and practical computing, including hands-on guides like setting up ACME certificate issuance and opinionated takes on AI tools and the patch-cycle burden. It reads as a first-person log of the author's experiments and observations rather than polished industry news.
