Newsletter of Carlos Santana - Issue #20
I'm finishing all my tasks before starting my PTO for the holidays.
While some of you are on the same boat shutting down, the Apache Log4J open source team and other DevOps teams had it rough this week dealing with a day zero CVE.
This week some folks were asking about my coffee time in Calendly, so I decided to create a portfolio/blog website https://santana.dev.
