Devops engineers are those who are good at debugging, troubleshooting, analyzing prod issues and providing solutions.Who have good hands on technologies like unix shell scripting, perl, sql etc.At first i thought this was the same as taking a cartesian product, but he used the usual $\prod$ symbol for that further down the page, so i am inclined to believe there is some difference.Does anyone …I'm trying to take the natural log, $\ln (l (\theta))$, but i'm not sure how this works with respect to $\prod$.Does anyone know what the process for this log is?
