Facebook Open-Sources Game Playing AI ReBeL
Facebook AI Research published a paper on Recursive Belief-based Learning (ReBeL), their new AI for playing imperfect-information games that can defeat top human players in poker. The algorithm combines reinforcement learning with state-space search and converges to a Nash equilibrium for any two-player zero-sum game. Code for training the algorithm to play Liar's Dice has been open-sourced.

The Challenges of End-to-End Testing of Microservices
Microservices work well with independent teams who have end-to-end responsibility and use an automated CI/CD pipeline. Ensuring software quality through end-to-end testing can conflict with rapidly integrating and releasing software components. If an end-to-end test fails, the CI/CD pipelines of all involved microservices are blocked until the problem causing the test to fail is solved.
