The name of this blog comes from the title of the first section of my introduction to computer systems textbook (CS:APP). The statement is literally true in computer systems – but it is a metaphor for what I want to write about, too.

I write about computer science, technology and cybersecurity. The bits. But I don’t want to ignore how they affect the world, and how the world affects them. The context. This blog is about both the code we write, and the world we write it in.
