Two tier network at home: DMZ for consumer stuff, "critical" for work. iPhone over android. Moving to yubikey for auth and code signing. Make sure that second-hand cars we buy don't come with adobe flash.
Still vulnerable to leakage of personal data from many sites, and wilful actions of installed phone apps like airline check in ones. Run 1+ of: Maven, apt-get or brew every single day on that critical development laptop
If I consider where I am most vulnerable, it is in that automated download and execution of developer tools and application libraries, To put it another way: the code I've written over the years runs on thousands of developer boxes every day. These people are relying not just on my competence, but my goodwill and the quality and detail of the peer review process in those OSS projects.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
