Highlights:

Web ads and ad scripts can slow down your system and gum up your web experience. Browser-based ad-blockers are useful for controlling many types of popups and banners, but they are less effective with ads built into applications – and they are often difficult to implement on mobile devices. This month we look at a couple of alternative tools for blocking ads at the network level: Pi-hole and Privoxy. Also in this issue:

  • Firewalld and OpenSnitch – a practical workshop on configuring firewalls for outgoing, as well as incoming, traffic.
  • Create a Personal Web Archive – Future-proof your bookmark library by downloading and archiving web pages.

Check out MakerSpace for a study of the tiny BBC micro:bit, and turn to this month's LinuxVoice for a look at how to build a unified game library with GameHub.
