Multiple times every day, you visit websites that ask you to log in with your username or email address and password. Banking websites, social networking sites, email services, e-commerce sites, and news sites are just a handful of the types of sites that use this mechanism.

Every time you sign into one of these sites, you are, in essence, saying, "yes, I trust this website, so I am willing to share my personal information with it." This data may include your name, gender, physical address, email address, and sometimes even credit card information.

Wed, 11/13/2019 - 16:02

Open source is everywhere. It's in your computer at home, it's in your computer at work, it's on the internet, and a lot of it is managed with Git. Because Git is decentralized, many people also think of it as a kind of crowdsourced backup solution.
