"CS Unplugged is a collection of free learning activities that teach Computer Science through engaging games and puzzles that use cards, string, crayons and lots of running around. The activities introduce students to underlying concepts such as binary numbers, algorithms and data compression, separated from the distractions and technical details we usually see with computers."
"This collection contains selected historically important software packages from the Internet Archive's software archives. Through the use of in-browser emulators, it is possible to try out these items and experiment with using them, without the additional burdens of installing emulator software or tracking down the programs. Many of these software products were the first of their kind, or utilized features and approaches that have been copied or recreated on many programs since. (historic software, vintage software, antique software)"
"Well, we are two Ukrainians who studied computer science at a university a while back. Both deeply passionate about computer science, sometime ago for our gradate work we developed an algorithm for detecting plagiarism in content. Once the project was completed, we saw what it has become. It was an amazing and useful tool for students and teachers to check if they or someone they know has plagiarized. Now finished with school, we thought this could really be useful to the public. So we gathered like-minded people to help make our service useful and popular throughout the world."

other university students started looking at a public transport's ticketing system because they were fans of public transport and interested in how the data was encrypted. They were also interested in what protections were in place against malicious users creating fake tickets
they were already aware of the potential flaws, but it was a large and expensive operation to change the tickets
cryptography should be impossible to crack, even if a potential attacker or reverse engineer knows every detail about how it is implemented. This system on the other hand is relying completely on users not knowing how it is implemented, which may have been fine when it was introduced in the early '90s because much fewer people had access to the technology required to read the tickets, or computers fast enough to analyse the data
"A team of university students in Sydney have cracked the secret algorithm used on Sydney's public transport tickets for buses, trains and ferries, which they say could allow them to print their own tickets.

But as we use the Internet for “free,” we have to remember that if we’re not paying for something, we’re not the customer. We are in fact the product being sold — or, more specifically, our data is.
So here’s a tricky question: Who owns all that data?
The digital divide isn’t about who owns data — it’s about who can put that data to work.
