Rust: The Longest War
Jonathan Waldman
Engineering
I write software for a living. But my major headache isn't writing it; it's maintaining it. Software, like any other engineered object, is subject to corrosion.
No, it doesn't literally corrode. It just behaves as though it does. Take a working piece of code. Leave it for six months. Try to run it. You'll almost inevitably find that something has changed. A file isn't where it used to be, or its format has changed, or the database is different, or something that I'm depending on doesn't work the same way, or a calculation has changed, or some assumption is invalid, or ... the list is endless.
The process is sometimes called "bit rot".
So I really liked Rust. Entropy is an absolutely inescapable portion of any engineer's life. It's manifestly stupid not to plan for it--and yet many engineers (or organizations) don't. Rust explains, in gory detail, why they're wrong. Plus I'm a sucker for any kind of book that takes some overlooked aspect of our world and delves into it.
I have a couple of quibbles. The chapters are individual essays--stories of people who are involved with corrosion in some way, including a pipeline engineer and an artist. They don't really link up into an overarching story. I wouldn't have minded more chemistry and physics, either.
Quibbles aside, though, this is a fine read. A couple of other books of the same sort spring to mind:
- Does the subject of the now-ubiquitous shipping container sound boring to you? Then you haven't thought enough about it; read The Box, by Marc Levinson.
- Similarly, does a book about human waste sound like something to make smirking jokes about? After you read The Big Necessity, by Rose George, it won't seem very funny.
