Digest of interesting materials for a mobile developer # 358 (August 17 - 23)

In this release, Lingualeo's move to PostgreSQL, major free software bugs, Epic's war with Apple, interface perceptions and the golden age of programming, the Weasley clock, user behavior, and more!





We asked our backend development leader, Oleg Pravdin, to talk about how he and his team, in parallel with supporting the main product, assembled a new modular service structure based on PostgreSQL, transferred business logic to databases, and migrated with millions of users. Today we will try to figure out why no one wants to use Open Source applications. The article turned out to be quite long, but don't be alarmed, it will be interesting.
