On Being A Technical Reviewer

While I don’t read as much fiction as I’d like, often favouring audio books from Amazon’s Audible while on the bus, I’m a bit of a sponge for non-fiction (number theory; the history of mathematics; quantum mechanics; web development; cloud computing and DevOps) and hoovering up everything interesting in my RSS reader.
