I ask how do you build quality software in interviews. A lot of people are caught completely flat footed by it. They have no idea.

Hetzner randomly shuts down one of my servers every 2-3 months.

Nice of them to test your failover for you.

OK, I can only speak to my personal projects and 20+ years experience at work.

We run all of our stateful and stateless workloads on 10+ kubernetes clusters at work in multiple datacenters in multiple continents, and we serve 500 million users a month with it.

I wrote the first BORG version of DFP backend systems at Google, where we served billions of users billions of ads a day, and we used stateful infrastructure management on some of the first container runtime systems that inspired k8s during it's development.

Using rabbit and "most databases" native fallover strategy is fine for toy projects, but when you're operating at this scale, you need automated infrastructure provisioning and all of the automated tooling around it.

That is scale I can't comprehend.

Quick math $33T US national debt times 5% is $1.65B. Federal revenue around $5B in 2022 so not quite there but very substantial.

I think you're missing several orders of magnitude on that math.

Maybe a T instead of a B.

Except kubernetes has a whole storage provisioning system that gives you redundancy and automatic failover, if you’re going to the trouble of running kubernetes why not just run your whole infra on it?

I run https://atomictessellator.com solo, using kubernetes, and my database, Minio object store, application servers, quantum workers, everything is all on kubernetes, it’s self healing and much simpler to run all the infrastructure the same.

Recently I had a node failure while I was sleeping and the whole system healed itself while I slept, the monitoring system didn’t even alarm me because the small blip of increased latency while the pods rebalanced wasn’t above the alert threshold so it didn’t even wake me up.

What happens in the article infra when the rabbitmq or database nodes fail? The whole system goes offline, which seems very silly setup when you have kubernetes sitting right there, who’s primary function is to handle all of this.

Rabbit and most databases have their own failover strategy. Putting it all on k8s is fine for a toy app but idk why anyone would deploy a real system like that.

I had the opposite feeling. Looking from the window, to your left, a winding road. To your right, the freeway entrance. With a bolt action rifle, Oswald had to shoot, eject the casing, reload, acquire the target of an accelerating vehicle, shoot, eject the casing, reload, acquire the target of an accelerating vehicle and fire again. One of the Marine Corps' top snipers said, "I can't do it." If he can't, how could Oswald?

The distance was like 75 yards. I visited the book depository as a child and even then thought I could make that shot.

I did not spent a few years in self driving, but correct if I'm wrong, but how would Waymo win when they can work only with HD maps (aka, nearly nowhere) while Tesla FSD work nearly perfectly now even on dirt roads (aka anywhere) with no map at all?

Captured the requests in a flash client used in a 6 hour defensive driving class to skip to the last page. Got my certificate. My friend did the same thing and the company reached out trying to figure out why they were getting all of these database errors...

The list is long. If you're familiar with c++ take a look at C#. Go and Java are safe bets as well. Beyond that there are a million backend languages out there.
