It turned out that many companies decided to rename the architectural pattern master/slave in their documentation due to its negative connotation. “Primary” and “Replica” are used in the documentation of IBM, Microsoft, Amazon Web Services, ACM, Python, Django, Drupal, CouchDB, Redis, and MediaWiki (the latter decided not to abandon “master”).

Update: I think it’s because in a true master-slave setup, only the slaves should work, while something like a zookeeper would be on the master.

Any pool players here? Today, I entered the office in our building where there’s a small room with a pool table, and decided to test how theoretical calculations stack up against practice. And somehow, nothing aligns for me. In theory, I calculated where to hit the ball so that after two bounces it would fall into the pocket. In practice, “the angle of incidence equals the angle of reflection” only applies to the first bounce, the second bounce behaves oddly. The ball almost flies backwards.

In red – what I expected, in blue – what actually happens. I understand that the ball might be spinning, but I really tried to hit it in the center, and with one bounce I even sometimes pocket the ball on the first try, with two I am still not skilled, and also the theory doesn’t hold up. But overall, I’m still “green” in pool. Why is that?

Can you guess the language?

P.S. First guessed by George Aristov and Fyodor Saveliev!

This is Glagolitic script. It’s late, 20th century. It is a distant relative of Cyrillic. Glagolitic was developed by Cyril and Methodius. All these “az buki vedi” – it comes from here. For example, the last word here is “PRISHESTVIYA”. Here’s the alphabet:

Update: Svetlana Beregulina and Roman Moguchiy helped figure it out again. The language is Old Church Slavonic or Croatian, hard to tell (Croatian originated from Old Church Slavonic, like Russian, but it is closer to that ancient language). And the script is Glagolitic. Actually, the question was about the script, but I called it a language.
