As someone who majored in CS and is now in a software engineering position, the people in tech who come from a completely different field are always my favorite. On top of just proving people wrong about the “right” way to get into the field, they’ve been around, they know how to think about problems from other perspectives, and they’re usually better at working with other people.
Honestly, I think more people should minor in CS, or if they did their undergrad in CS, they should have to do their grad work in something else. The ability to compute things is only useful if you’re well versed in a problem worth computing an answer to, most of which lie outside of CS.
Normal for who? I wouldn’t expose SSH on 22 to the internet unless you have someone whose full time job is monitoring it for security and keeping it up to date. There are a whole lotta downsides and virtually no upsides given that more secure alternatives have almost zero overhead.
