The other person may have responded with a fair amount of hostility, but they’re absolutely correct. I run Kubernetes clusters hosting millions of containers across hundreds of thousands of VMs at my job, and OOMKills are just a fact of life. Apps will leak memory, and you’re powerless to fix it unless you’re willing to debug the app and fix the leak. It’s better for the container to run out of memory and trigger a cgroup-scoped OOM kill. A system-wide OOM kill will murder the things you love, shit in your hat, and lick your face like David Tennant licked Krysten Ritter.
I’ve always heard that seismic activity makes hyperloop-style transit effectively impossible.*
† Impossible given the constraints of current materials science. From what I’ve read (which may be garbage, but it seemed well researched), making a vacuum chamber that’s hundreds of thousands of miles long on top of a big wiggly molten goo ball isn’t something we can even see a way to realistically achieve right now.
