Somewhat related: are downloading and storing webpages practical nowadays? The Web is obviously invaluable, but even in this day and age the infrastructure isn't perfectly reliable from the perspective of an end user. And there is a sea of irrelevant information that you can get sucked into. I was wondering if it would be possible to download (and update at regular intervals) websites which I can then use in my browser even when I'm offline. Something like downloading Wikipedia and perhaps all of Stackoverflow. If that works, I could get a lot of useful information even if I'm working in a location with no Internet/bad Internet connection. Or maybe I'm even sitting in my cubicle and purposely disconnect the Internet to stay more focused! (The problem then would be that I've grown too accustomed to streaming music through Spotify...)
