On the non-technical side, I am re-reading Perdido Street Station by China Mieville. This is an incredible non-traditional fantasy novel that breaks free of the usual Tolkienian cliches that hurt the genre. I highly recommend it. I also very recently started reading The Blade Itself by Joe Abercrombie, which I’ve heard good things about.
As for technical reading, I am slowly making my way through Working Effectively with Legacy Code by Michael Feathers. It is full of great advice on how to gradually transform nasty codebases into unit-tested and well-factored ones. I have a bad habit of trying to completely rewrite rather than gradually refactor legacy code, and this book has been very helpful in that regard.
The Blade Itself is a good read. If you enjoy it, for something very different but equally fantasy trope breaking, have a look at The Vagrant by Peter Newman, and on the sci-fi end, Children of Time by Adrian Tchaikovsky
This is really great, I love the interface.
