Thanks! I'm glad you liked it. It was more of a way to walk away from Reddit, really. Some people asked for the challenge to be on Lemmy, I just listened to them.
Yep, but since VirtualBox can be used in any guest OS and a lot of people come here still using Windows, I sort of simplified the tutorial by just focusing on it so far. I want to expand the "doing things locally" in the future and I accept suggestions on our GitHub.
Anki is awesome but the best way to memorize commands is to just use them. After you are finished with the challenge you may want to consider practicing with real world scenarios at https://sadservers.com/
In a production environment? Not really, there are better ways to do it. But it's a good beginner exercise.
Oracle is mentioned alongside AWS and Azure free tiers on the other Day 0 article.
I'd love to add more material about containers, if you have any recommendations please share.
Agreed, Oracle is as devilish as IBM, but I didn't see any major discrepancies with their Ubuntu version (so far) like I saw on IBM Cloud. It's a cloud option, but definitely not my first pick.
No need to reboot, it's just a recommendation after your first update/upgrade to get any kernel changes in. You won't need to reboot for a long time after that.
Nice to know! Thanks for sharing.
It's really up to you. I've been doing some improvements to the material lately, so next month will be slightly different (but not much).
