GNU Parallel, where have you been all my life?
Summary: Alex Plescan shares his experience using GNU Parallel to efficiently run end-to-end tests and gather flakiness stats. GNU Parallel allows for executing commands in parallel, providing better performance and functionality with less code. Plescan demonstrates how to control concurrency, capture output in a CSV file, and monitor progress. He recommends the book by Parallel's author Ole Tange for further exploration of its capabilities, such as distributing jobs across different hosts and resuming jobs if parallel execution stops midway.

Study: Inflammation drives social media use
Summary: A University at Buffalo study found that inflammation, the body's response to injury and infection, can lead to increased social media use. The research, involving over 1,800 participants, showed that higher levels of C-reactive protein (CRP) promote social media use among middle-aged adults and college students. This is the first evidence of the immune system's role in social media use. Understanding this connection can inform intervention strategies for managing social media use and seeking social support.
