An attacker has gained access through security misconfigurations in an API server, escalated privileges, and deployed cryptocurrency mining pods that consume massive resources. The DevOps team spends the day containing the damage and now faces tough questions from leadership about how this happened.

It almost sounds pejorative, doesnt it? But the distinction between senior and junior software developers is built into our jobs and job titles. Whether we call it entry-level or something else, we distinguish between people who are just starting their careers and those who have been around for a while. Were all still learning (one hopes), but entry-level people are still learning the basics, and seniors have greater responsibility, along with the potential for making bigger mistakes.

Scheduling is crucial in computer system design. The right policy can significantly reduce mean response time without needing faster machines, effectively improving performance for free. Scheduling also optimizes other metrics, such as user fairness and differentiated service levels, ensuring some job classes have lower mean delays than others [1]. MySQL 8.0 uses the Contention-Aware Transaction Scheduling (CATS) algorithm to prioritize transactions waiting for locks.

With the release of MongoDB 7.0 in August 2023, we introduced a feature called Queryable Encryption , the first of its kind. With queryable encryption, your data is encrypted, even at rest, with the server unable to read it either but still able to execute queries against it. You can specify what fields to encrypt so you can encrypt as much or as little of your document as you need.
