An assertion documents the expected state of specific program variables at the point where the assertion is written, in a testable way so that we can find program bugs — logic errors that have led to corrupted program state. Assertions are only about finding bugs, not doing program work.

Before we dive into the differences between MariaDB and MySQL, we will provide a thorough examination of each relational database management system (RDBMS). While originally designed to be a drop-in replacement for MySQL, it evolved into its own distinct database management system and is now maintained and supported by the MariaDB Foundation.

These techniques work well for scientific programs that are dominated by arrays. However, they are ineffective on object-based programs because objects do not fall neatly into fixed-size blocks and have a more irregular layout. If we compress objects instead of cache lines though, we can get to a 56% compression ratio (c).

First, a bit of operating-system design context. It is desirable for a program to be able to go to sleep and then wake up a little while later. Ideally the CPU goes to sleep when Sleep(1) is called, in order to save power, so how does the operating system (OS) wake your thread if the CPU is sleeping?
