The text in these files is the unedited original manuscript. M-K has fine copy editors, who have fixed all the minor typos, spelling, and grammar errors in the printed book, but if you come across factual errors I'd still appreciate help getting all the details of linking and loading as complete and correct as…

Unikernels are customized, single address space bootable images composed of an application and the required bare-minimum kernel functionality. Today’s unikernels have demonstrated substantial performance and security advantages over monolithic and microkernels, but none have yet achieved widespread adoption. The…
By far, the worst part of working on beets is dealing with filenames. And since our job is to keep track of your files in the database, we have to deal with them all the time. This post describes the filename problems we discovered in the project’s early days, how we address them now, and some alternatives for the…

In this article I give a brief tour of a program analysis technique called symbolic execution. As the title indicates, I aim to explain both the intuition behind the technique, and also the details of a simple implementation. My intended audience is professional programmers who have no background in program analysis.
I know that a lot of people struggle with understanding the memory model introduced in C11/C++11. In a recent conversation I was alerted to the existence of this blog post, which while correct (by …
The open source operating system that runs the world.
Linux containers, Kubernetes, artificial intelligence, blockchain and too many other technical breakthroughs to list all share a common component - Linux, the same workhorse that has driven mission-critical, production systems for nearly two decades. Today, we’re offering a vision of a Linux foundation to power the…
As a rule, "sophisticated" progrmming is pretty boring - optimizing the unnecessary to speed up the uninteresting. Here, however, is an incredibly sophisticated package intended for fun and games. The more you know about software, the more astounded you will become as you read this.
