They open up, like you’re heading somewhere dark. How To: Stare at the middle and let it build.

Using Pi-hole Dns in Neighboring Docker Containers

It’s a great tool for taking control over your DNS and blocking trackers and ads across the whole network. Once the network’s DHCP 1 server is configured, every machine on the network will begin sending its DNS queries to the Pi-hole container. But what about Docker containers that share the same Pi-hole host — what I’m calling “neighboring Docker containers”? Can they also use the Pi-hol

What Could Split a Black Hole in Two?

We all know that black holes can collide. It has happened since black holes began to form, early in cosmic time. The result is always a clash that gives off gravitational waves and a giant bang. Since black holes have such strong gravity, it's almost impossible to imagine a way that any force could break one apart. Yet, that's the task that a group of scientists in Europe set for themselves.
