I've become a big fan of CultRepo's documentaries. If you enjoyed this one, I highly recommend checking out their catalogue of free, high-quality content (https://www.cultrepo.com/films).

They cover a wide range of topics, from C++ and Java to Node.js, Kubernetes, React, and Vue.js. I particularly enjoyed the Java documentary, which offered fascinating insights into the differences between the Sun and Oracle eras, many of which I never would have expected.
