Veritasium tells the story of the XZ backdoor, how a patient attacker became maintainer and nearly compromised SSH on Linux systems. It also covers free software history and how encryption in SSH works.

Harvard professor Arthur Brooks explains why boredom is useful rather than something to avoid. He describes how a wandering mind engages the brain's default mode network, which supports creativity and curiosity, and suggests it may protect against depression.

Netflix engineer Drew Gallatin explains how Netflix serves TLS-encrypted video at 400Gb/s from a single FreeBSD server. He covers NUMA, kernel TLS, hardware TLS offload and the memory bandwidth and PCIe bottlenecks they hit.
