System design questions always start the same way: "Design twitter for 100 million users."
So we add load balancers, kafka, redis, ten services. Nobody asks who pays for it, or who fixes it at 3am.
The other question is rare: what can one person build with one small server?
Yes, these questions test if you know distributed systems. But building with limits is a skill too, and almost nobody asks about it. And it’s the one most of us face at work.

Hi Nostr, I'm new here.
A few updates from this year: I left my job and started a small company. Plus some Scala, Death Stranding and Dune.
