In the past few years, CPUs have gotten really fast. Shockingly fast! Yet most people are stuck on previous generation mobile chips (whether by choice, or by their companies choice), at a huge detriment to their productivity.

How do Unix pipes work?
Pipes are cool! We saw how handy they are in a previous blog post . Let's look at a typical way to use the pipe operator. We have some output, and we want to look at the first lines of the output. Let's download The Brothers Karamazov by Fyodor Dostoevsky, a fairly long novel.
