1. WebRTC

The Web Real-Time Communication is a free and open-source project providing web browsers and mobile applications with real-time communication (RTC) via application programming interfaces (APIs). It allows audio and video communication to work inside web pages by allowing direct peer-to-peer communication, eliminating the need to install plugins or download native apps...

2. CRDTs

A Conflict-free Replicated Data Type (CRDT) is a new type of data structure¹ that can be replicated across multiple instances in a network with the following guarantees:

{{1}}

1. A replica can be updated independently, concurrently and without coordinating with other replicas.

2. Inconsistencies can be resolved automatically.

3. Although replicas may have different state, they are guaranteed to eventually converge.

   {{2}} Task: Implement an distributed counter

What have Poland and Arnold Schwarzenegger in common?

            {{1}}

Poland Is Pioneering the World’s First National Open Textbook Program

Access to educational materials varies considerably across the world. Many in low- and middle-income countries do not have textbooks, and the ones that exist are often out of date. Two recent initiatives in Poland, however, are getting free, open textbooks into classrooms—textbooks that are available online and can be easily adapted, translated, and improved upon by teachers and students...
