docker’s userns-remap feature allows us to use a default dockremap user. In this scenario, docker engine creates the user dockremap on the host and maps the root user inside a container to this user. For this user, docker also needs to have entries on the host’s /etc/subuid and /etc/subgid files.

58 bytes of css to look great nearly everywhere

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

XTRACT ZE FILES!

xzf, XTRACT ZE FILES!, is a utility for file extraction, as you may have guessed. Inspired by xkcd and general boredom. Works on both python v2.7 and v3.3.
