For the longest time I did not know what everything meant in htop.

I thought that load average 1.0 on my two core machine means that the CPU usage is at 50%. That's not quite right. And also, why does it say 1.0?

I decided to look everything up and document it here.

They also say that the best way to learn something is to try to teach it.

ddgr is a cmdline utility to search DuckDuckGo from the terminal. While googler is highly popular among cmdline users, in many forums the need of a similar utility for privacy-aware DuckDuckGo came up. DuckDuckGo Bangs are super-cool too! So here's ddgr for you!

Unlike the web interface, you can specify the number of search results you would like to see per page. It's more convenient than skimming through 30-odd search results per page. The default interface is carefully designed to use minimum space without sacrificing readability.

A big advantage of ddgr over googler is DuckDuckGo works over the Tor network.
