A byte string library for Rust
bstr is a byte string library for Rust and its 1.0 version has just been released ! It provides string oriented operations on arbitrary sequences of bytes, but is most useful when those bytes are UTF-8. In other words, it provides a string type that is UTF-8 by convention , where as Rust’s built-in string types are…

Systems that defy detailed understanding
Last week, I wrote about the mindset that computer systems can be understood, and behaviors can be explained, if we’re willing to dig deep enough into the stack of abstractions our software is built atop. Some of the ensuing discussion on Twitter and elsewhere lead me to write this followup, in which I want to run…

Building a Distributed Log from Scratch, Part 1: Storage Mechanics
The log is a totally-ordered, append-only data structure. It’s a powerful yet simple abstraction—a sequence of immutable events. It’s something that programmers have been using for a very long time, perhaps without even realizing it because it’s so simple. Whether it’s application logs, system logs, or access logs…

How to zero a buffer
Now, we don't want to truly change the observable behaviour of our software — but fortunately the C standard has a more liberal concept of "observable" than most people. In particular, the C standard states that the observable behaviour includes accesses to volatile objects . What is a volatile object, you ask? It is…

How to do distributed locking
As part of the research for my book , I came across an algorithm called Redlock on the Redis website. The algorithm claims to implement fault-tolerant distributed locks (or rather, leases [1]) on top of Redis, and the page asks for feedback from people who are into distributed systems. The algorithm instinctively set…

My Own Private Binary: An Idiosyncratic Introduction to Linux Kernel Modules
Several years ago, I spent a serious chunk of time figuring out how to make really teensy ELF executable files. I started down this path because I was annoyed that all of my programs, no matter how short they were, never got smaller than 4k or so. I felt that was excessive, for C, and so I started looking at what ELF…

First fully sandboxed Linux desktop app
Its not a secret that I've been working on sandboxed desktop applications recently. In fact, I recently gave a talk at devconf.cz about it. However, up until now I've mainly been focusing on the bundling and deployment aspects of the problem. I've been running applications in their own environment, but having pretty…
