8. Moodle
   Tinkered by Martin Dougiamas while pursuing his PhD at Curtin University. Powers online classrooms at Cambridge, Oxford, and Caltech.
   Canvas and Blackboard step aside.

   Created by the Stanford NLP group. Annotates, parses, and performs sentiment analysis on any text.
   Better than Google Cloud’s Natural Language API, and free.
   Go to → https://stanfordnlp.github.io/CoreNLP

10. R
    Created by the University of Auckland. The go-to language for statisticians, biology labs, and government agencies for data analysis.
    Makes SAS’s $9,000 annual fee embarrassing.
    Go to → https://r-project.org

Berkeley created PostgreSQL—the foundation of half the internet.
Berkeley also created Apache Spark—the engine for half of the Fortune 500.
MIT and Harvard created Open edX—many countries’ online education systems run on it.
Stanford created CoreNLP—almost every NLP paper in the past decade has cited it.
