The missing guide to the Internet, cybersecurity & data science—for FREE
A high-level overview of networking, data science and computer security. Designed for readers who don’t care for academic formalities, it’s a fast and easy guide. It teaches the foundations programmers need to thrive in the digital age.
Programming is all about manipulating data using computers. To become a great programmer, it’s very important to learn the concepts of how to interpret data, and how to extract meaningful knowledge from it. This book will teach you how to collect, process and aggregate data the same way the best data scientists do. It will also teach you the basics of machine learning: using data from the past to predict the future.
The Internet provides an amazing ability to link our planet and enable multiple participants to collaborate on the same data. It enabled the email, the web, online social networks, and so much more. The programmers behind such breakthroughs need to have a firm understanding of how the Internet works—and so do you. This book will demystify the magic and demonstrate how linked computers communicate in order to form the Internet.
Finally, manipulating lots of information through the Internet is powerful, but also dangerous. When the information is captured by hackers, terrible things can happen. Fortunately, hackers can’t defeat strong encryption if the right measures are taken. Hence, learning the basics of how encryption protects you and your data is fundamental. This book will give you a running start to the basics of ciphers, digital signatures, and security vulnerabilities.

Praise for the book
“Computer Science Unleashed is a beautiful, rich and fun experience for anyone who’s into technology and wants to understand the modern world a little better. The authors expertly present very complicated topics in a friendly manner. It is truly engaging to follow along examples and use-cases as you learn how the internet works, or how a hospital may collect and use data to better help its patients.
I strongly recommend it to anyone with no tech background to dive in and take a look at how computer science shapes our lives. And I also recommend it to folks that already work with data and technology for gaining broader insight and choosing areas to study further.”
