About

This document outlines the configuration of a systemd unit designed to run the Playwright MCP server. The setup is opinionated, adhering to the Filesystem Hierarchy Standard (FHS) and the curated SELinux policies found in Fedora and Red Hat Enterprise Linux distributions.

Rootful Container Execution

This systemd unit runs the Playwright MCP container in "rootful" mode, meaning the container is managed by a podman process running as the root user. This is in contrast to Podman's default and more secure "rootless" mode, which allows non-privileged users to run containers. Running as root is a deliberate choice in this configuration, often necessitated by requirements like binding to privileged ports below 1024.

Networking and DNS

This is just a dump of some interesting undocumented features of webOS (3.8 specifically, on early 2018 4k LG TV) and other development-related tips.

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

A Brief Tour of the Makepkg Process: What Makes a Pacman Package

Introduction

This is a terse document covering the anatomy of a package built for the pacman package manager.

The following example commands can mostly run verbatim to manually create a

Long Live CoffeeScript and Long Live ES6

Clearly ES6 is a huge improvement over ES5, and tools like [6to5][] allow us to use these cool features now. I was reading [Replace CoffeeScript with ES6][replace coffeescript] by [Blake Williams][] and thought it was a great summary of how ES6 solves many of the same problems that CoffeeScript solves; however I'd like to comment on a few of Blake's points and talk about why I'll be sticking with CoffeeScript.

Classes

Classes in ES6 (like many of the syntax changes in ES6) are very similar to the CoffeeScript equivalent. To support browsers that are not fully ES5 compliant (e.g. IE8-), however, we still can't really use getters/setters, so ignoring these the comparison is:

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).
