Part 2 Core patterns

Core patterns are those that we use over and over, almost to the point at which they become clichés. So it’s vital for our success to master these core patterns and understand them well. Also, we need to make sure that we speak the language of patterns in a way that enables us to communicate our systems and designs to other people.

Occasionally, it’s good to remember that patterns are not the goal. We may need to step back from our work and view it from a higher level to ensure that we’re not applying patterns mindlessly without understanding the problem we’re trying to solve.

The goal of software design is rarely to use all the features of a language or maximize the number of lines of code. Rather, the goal is to ...

Julian F.

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.
