WE ARE A CLEAR AND PRESENT DANGER
WHAT IS A SECURE CONNECTION TO THE INTERNET?
Cellular connections (not Wi-Fi) are encrypted and SECURE.
Wi-Fi at Universities, Hotels, Libraries, Coffee Shops, etc.
IS NOT SECURE. Any computer on those networks may have
malware harvesting EVERYTHING you say, type and read.
When using a public Wi-Fi network use a VPN. A VPN secures
your device's internet connection to guarantee that all data
you are sending and receiving is encrypted and secure from
prying eyes. Iowa State requires its students to use a VPN.
Some excellent VPN services: Tunnelbear, ExpressVPN, ProXPN,
NordVPN, and TotalVPN.

Dropbox (Free service for all platforms)
Dropbox is a file hosting service operated by Dropbox, Inc.,
headquartered in San Francisco, California, that offers
cloud storage, file synchronization, and client software.
Dropbox allows users to create a special folder on each of
their computers, which Dropbox then synchronizes so that it
appears to be the same folder (with the same contents)
regardless of which computer is used to view it. Files
placed in this folder also are accessible through a website
and mobile phone applications.
One can backup specified files and folders to Dropbox using
symbolic links via the command line. For example:
ln -is ~/Documents ~/Dropbox/Documents
Anything added, deleted or changed on the PC/Mac is replicated
in Dropbox and vice versa. Deleting File/Folder in Dropbox
also deletes it immediately from the PC/Mac! Just so you know.
