A new book, some new friends ❤️

9 months after a group of otters taught us about event streaming and Apache Kafka, Round Robin is proud to announce our second book. This time, we partnered with best-selling author, Martin Kleppmann, and Gently Down the Stream author and illustrator, Mitch Seymour, to bring you a story about cryptography.

The annual autumn dance is being held in the forest, and two bunnies are deciding who they will ask to the dance. As they pass notes between each other in class, they realize they need a way of keeping their messages secret. They develop a technique that allows them to securely talk to each other without any chance of other bunnies listening in on their conversation. In doing so, the bunnies give us a memorable example of symmetric-key encryption and key exchange protocols that readers will find fascinating and useful.

With hand-drawn imagery and gentle explanations of cryptography concepts, this book will captivate beginners of all ages and backgrounds. Please check it out!

Stuffed Animals

An extremely limited supply of custom, handmade felt animals are available from a toymaker and friend in Ukraine. This requires a Friendship Pass, and each animal can take up to two weeks to create. The materials are sourced from Ukraine and proceeds are donated to the Ukrainian toymaker and his family, whose lives and business have been upended by the war.
