Hey, thanks to everyone for the kind upvotes. Hopefully it will be useful. For those who somehow don't already know, we also build a free, open source, android app with tons of guides on digital and physical security - called Umbrella. We are currently doing an update of content and features (more at www.secfirst.org)

Available on Google Play, Amazon, F-Droid Repo etc:
