To actually answer your question, you need some kind of job scheduling service that manages the whole operation. Whether that’s SSM or Ansible or something else. With Ansible, you can set a parallel parameter that will say that you only update 3 or so at a time until they are all done. If one of those upgrades fails, then it will abort the process. There’s a parameter to make it die if any host fails, but I don’t recall it right now.

I was trying to think of a way to trick him into planting bamboo in his yard, but those are good.

What tech field though? Software? Cloud? AI/ML? Security?

In all those scenarios though, the cert in question would be listed as something else. It’s not that I’m against Coursera or think it’s a bad platform.

There are a lot of certs out there and most of them are worthless, and a lot of them happen to be on Coursera, I guess. I’ve talked to people who had AWS certs and couldn’t explain the difference between S3 and EBS. Certs just don’t mean much.

Once you get your first job, the certs of all kinds just become resume fluff, but since you are pursuing your first job, they might be useful.

As an interviewer, I think that certs are only useful if you take the test with a different company than you studied with. So I don’t think I’d care if you have a coursera cert, because I’d assume it just meant you finished the course that you paid for.

What certs are you thinking about doing, and more importantly, what are you looking to get out of them? I know “a job”, but what kind of job are you looking for?

It actually doesn’t, because the drive won’t “let” you overwrite the reserve space. That’s why they introduced SSD secure erase, so the firmware knows that you mean to overwrite everything.

Alternatively you could just use full disk encryption and burn the key when you are done.

Just do it. It’s not hard, it just takes time to learn all the pieces and how they fit together.

Do you have location tracking turned on? I feel like a few times when people looked into this, it came down to the Taxi app having location sharing on (so the app can show you fairs, of course) and that the fact that you wrote something about needing a taxi is irrelevant because the app knows you are someplace where you might need a taxi.

And maybe someone nearby you who also had the same Taxi app had just booked a trip. They can correlate your location and people around you.
