I just finished an amazing call.

[release_candidate@mastodon.bsd.cafe]

@mvilain @stefano I ask sometimes what exactly is a container. If the candidate never mentions cgroups or namespaces, then I conclude that she/he doesn't really know.

Most of the times I just get answers like methaphores of sandboxing and how it's 'not a vm, but like a vm'.

@stefano WAAT? 😆🤪

[bms48@mastodon.social]

@stefano Epic Fail.

[trrektor@ieji.de]

@stefano it's worse: he needs linux on freebsd to run docker

[coreysnipes@hachyderm.io]

@stefano whew! well done.

@stefano If they are looking for an expert on docker, they are rejecting everyone who knows something about docker.

@stefano

It's so infruriating the other way too. I was being interviewed by a "very smart boy" about algorithms for a job. He asked how to multiply very large numbers, then kept overtalking me when I was trying to explain how to do it with an FFT.

"No, that's for signal domain transformation"

"No, I asked about multiplying numbers"

In the end he did me a favor, because I would rather defenstrate him than work with him. I did email him this after our interview:

@stefano my blood pressure just skyrocketed while reading your toot. Wow… just wow… but bullet dodged I guess?

Gotta have the right pants for all the Dockers.

[caffetino@social.pikaia.org]

@stefano nicely done!

@maysonic @paul_ipv6 @stefano I spent 9 months working for a startup as their build engineer/AWS admin. They developed an application that made local storage available to containers without using network or the file sharing mechanism before kubernetes existed. I knew nothing about Docker and it's ecosystem prior to the job and learned a lot. Things have evolved in the 7+ years since then but containers haven't changed all that much.

If I knew then what I know now, I'd have worked harder to push my boss to accept more automation but he only wanted to implement what he knew and understood. Even with the stuff I wrote, the 2 developers I "trained" on my stuff still had deer-in-the-headlights stares through the class I gave the day I left. I also left all the dirty dishes in the sink rather than rinsing and putting in the dishwasher while I made my last cup of tea in the microwave. I shoulda taken a picture.

@release_candidate @mvilain @stefano
Sure, cgroups and namespaces are implementation details on Linux. But probably(*) the specification of a container doesn't require that those specific technologies are used. Docker/podman on a macintosh runs in a VM, and if I recall correctly, docker on NetBSD works similarly.

(*) I didn't look it up
