I just finished an amazing call.

@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?

[passthejoe@snac.bsd.cafe]

Gotta have the right pants for all the Dockers.

[caffetino@social.pikaia.org]

@stefano nicely done!

[mvilain@sfba.social]

@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

@stefano never play chess with a pigeon!

See also, the numerous conversations I've had with people who claim a NAS is not a server.

[jabgoe2089@hub.netzgemeinde.eu]

@Stefano Marinelli well, what else is there to say ? :-)

[linker3000@mastodon.social]

Ha. They're thinking of Podman, which doesn't need a kernel because it's daemonless...

..or something like that.

🤔😁

@release_candidate@bsd.cafe
i would at least find a way to rant about plan9's per process namespaces if randomly asked about containers. and if i counted on being asked about them intentionally, i'd be sleeplessly diving into anything i could get my hands on.

(my role is nothing to do with sysadmin stuff, i'm just a helpdesk person who messes around with snac & stuff in their home in simple noncontainerized ways of yore; i dont know what a microservice is and am too afraid to ask)

"not a vm but like a vm" is... um... a small part of me would want to tell them the janitor interviews are one floor below.

[ska@social.treehouse.systems]

@stefano You are wise in ways I can never be.

[mikestok@mstdn.ca]

@paul_ipv6 @maysonic @mvilain @stefano or find another job. Like many other things that are meant to make my life easier, it seems to me that docker lures me onto thin ice from time to time. And I hope I’m still too young to die.

[edelruth@mastodon.online]

@stefano

Hey, plainly he read a thing, or did his own research, or, like that.

[chessert@mastodon.online]

@stefano

You certainly dodged a bullet there: well done! 🙂

“Please go be someone else’s headache.”

[aadmaa2@mathstodon.xyz]

@stefano awesome. This is a big security win. I can quit fiddling with gvisor.

[earthorguk@mastodon.energy]

@stefano Ah well, in the 80s as an ignorant teen I asked the creator of B to tell me why I should by a C compiler. He was fairly polite about it...

[pertho@mastodon.bsd.cafe]

@stefano Wow this person must have drunk ALL of the docker Kool-Aid.

[jae@mastodon.bsd.cafe]

@stefano a bullet you dodged. possibly two of them. but in typical stefano form, a professional
