Nothing is so firmly believed as what we least know.

M.E. De Montaigne, Essays, 1580

Talk sense to a fool and he calls you foolish.

Euripides, TheBacchae, 407 B. C.

But talk nonsense to a fool and he calls you a genius.

9.1 State-of-the-Art Review

As introduced in the previous chapter, capacitance introduces additional reactive power, resulting in power factor correction. This chapter, however, provides a voltage improvement along the feeder without the use of reactive power injection. A paper was introduced in the early millennium with an advanced method to regulate voltage along a feeder with coordination of interconnected energy storage and distributed ...

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
