What would you like to hear about from someone who is working in Linux Systems from Nepal? Do tell your demographics.

I am interested in making couple of bucks (pocket money) <50$ per month from blogging+youtube channel videos. Wondering how much doable is this with affiliates, promotions, adsense. How much traffic should I be getting?

What content would people be interested in seeing and what content would I be able to make?

I am working as a devops support engineer since 2 years. That's all my experience.
