Two sets of presentations from two very different conferences (KubeCon and DevSecCon) this week, all published within a week or so of the event and free for everyone to watch and read. The fact this is becoming the norm means a pretty amazing learning resource exists for even the latest technology or thinking. Good job conference folks.

Tools

Storing credentials in your shell profile and exporting them as environment variables is incredibly handy but very insecure. Envchain looks to provide the same ease of use but to use OS X Keychain or gnome-keyring as the backing service.
