Harden and Secure Linux Servers by Level (1 - 6)

Securing a Linux server is an ongoing challenge. Every day, bad actors attempt to penetrate systems worldwide, using VPNs, IP spoofing, and other evasion tactics to obscure their origins. The source of an attack is often the least of your concerns, what matters most is implementing strong security measures to deter threats and protect your infrastructure. Hardening your servers not only makes them more resilient but also forces attackers to either move on or, ideally, abandon their efforts altog

Feeling Like I Have No Release: A Journey Towards Sane Deployments

by: Lee Meyer Mon, 07 Apr 2025 14:41:53 +0000 When I was young and dinosaurs walked the earth, I worked on a software team that developed a web-based product for two years before ever releasing it. I don’t just mean we didn’t make it publicly available; we didn’t deploy it anywhere except for a test machine in the office, accessed by two internal testers, and this required a change to each tester’s hosts file. You don’t have to be an agile evangelist to spot the red flag. There’s “release early

A New “Web” Readiness Report

It happened to me while writing an Almanac entry on @namespace, an at-rule that we probably won’t ever use and is often regarded as a legacy piece of CSS. Maybe that’s why there wasn’t a lot of info about it until I found a 2010s post on @namespace by Divya Manian. The post was incredibly enlightening, but that’s beside the p

Crafting Strong DX With Astro Components and TypeScript
