I just finished an amazing call.

SSD Supersonic Spinning Disc 😆

It's amazing how they fit motors to spin it and move the head on platters into a tiny 1.5mm x 12 mm package (approx). A miracle of nanotechnology!

In a way the reality is much stranger.

I remember when some people thought the CRT was the computer and the cased PC was the "hard disk". Some thought a 3.5" floppy was a hard disk (if they had first encountered cassettes and 5.25" floppies.

@paul_ipv6 @mvilain @stefano As one who has written device-driving code in assembly languages, I don’t really know how Docker works, but if you’ll pay me, I’d be quite willing to research it and explain it to you at whatever level of detail you’d like…

[paul_ipv6@infosec.exchange]

@maysonic @mvilain @stefano

i have every confidence that if using docker became part of your job, you'd spend the time to learn what was going on under the hood. :)

@Yendolosch @stefano Maybe Stefano could still offer him a nice game of chess

[maysonic@twit.social]

@paul_ipv6 @mvilain @stefano Given that the main computer-related income I’ve received since #y2K has been a shareware check for a Mac INIT I wrote in the 80’s, and a few free lunches from a friend whose Windows machine I removed a few viruses from, the likelihood of my employment requiring using Docker is fairly slim. It is possible that I may want to learn it anyway, if some side project (not that these days I really have any non-side projects) seems to need it.

[rasur@mastodon.social]

Oof, cubed 🥴

[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? 😆🤪

@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!

[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
