What are some of the ways that the first edition of 'Code' was becoming outdated?

Technical books are notoriously challenging to write due to the constantly changing subject matter.

What was your process for determining how to segment the information that you wanted to address in the book to balance the pacing of the reader with the density of the information?.

Why do you think that it is useful/important for a general audience to understand the electrical engineering principles that underly modern computers?

The sequencing of the topics parallels the curriculum of a computer engineering course of study.

Who is the target audience for the book?.

Can you start by describing the focus and goal of 'Code' and the story behind it?.

Your host as usual is Tobias Macey and today I’m interviewing Charles Petzold about his work on the second edition of Code: The Hidden Language of Computer Hardware and Software.

And don’t forget to thank them for their continued support of this show! Go to /linode and get a $100 credit to try out a Kubernetes cluster of your own. And now you can launch a managed MySQL, Postgres, or Mongo database cluster in minutes to keep your critical data safe with automated backups and failover. With their managed Kubernetes platform it’s easy to get started with the next generation of deployment and scaling, powered by the battle tested Linode platform, including simple pricing, node balancers, 40Gbit networking, dedicated CPU and GPU instances, and worldwide data centers.

When you’re ready to launch your next app or want to try a project you hear about on the show, you’ll need somewhere to deploy it, so take a look at our friends over at Linode.Hello and welcome to Podcast._init_, the podcast about Python and the people who make it great!.

In this episode he discusses what motivated him to revise that work in the second edition and the additional details that he packed in to explore the functioning of the CPU. Charles Petzold wrote the book 'Code: The Hidden Language of Computer Hardware and Software' to make this a less opaque subject. Most people, and many software engineers, don’t have a proper understanding of how that hardware functions. Software is eating the world, but that code has to have hardware to execute the instructions.
