I just finished an amazing call.
The person I was talking to was trying to explain to me that Docker is an entire operating system, so he doesn’t want Linux or any of the BSDs, but Docker. I explained that, in order to run Docker, you need a kernel."No, you don't. Docker does everything on its own. If you think that, then you don’t really understand operating systems."
I told the guy that I couldn’t help him, since I'm not experienced enough with operating systems. He was a bit disappointed, but we said goodbye on friendly terms.
I'm used to recognizing when I'm too ignorant for the person I'm talking to, and I'm happy to step aside.

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

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?

@stefano nicely done!

@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.
@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 The Dunning-Kruger is strong in this one. I asked a candidate what the difference is between a VM and Docker container. Interview ended shortly after that question.

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.

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

@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.

@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...

DIY Reflow Plate Runs On USB Power Delivery
If you’re working with surface mount components, you’re likely going to want a reflow plate at some point. [Vitaly] was in need of just such a tool, and thus whipped up a compact reflow plate that is conveniently powered via USB-C.
This reflow rig is designed for smaller work, with a working area of 80 mm x 70 mm. There are two options for the heating element—either a metal core PCB-based heater, or a metal ceramic heater. The former is good for working with Sn42Bi58 solder paste at 138 C, according to [Vitaly], while the latter will happily handle Sn63Pb37 at 183 C if the dirty stuff is more your jam.
Running the show is an ESP32-C3-WROOM, which serves up a web-based control panel over Bluetooth for setting the heating profiles. Using Bluetooth over WiFi might seem like an odd choice at first, but it means you don’t have to add the hot plate to the local wireless network to access it, handy if you’re on the move. It’s also worth noting that you can’t run this off any old USB charger—you’ll need one compatible with USB Power Delivery (PD) that can deliver at least 100 watts.
If you’re needing to whip up small boards with regularity, a hotplate like this one can really come in handy. Files are on GitHub for those eager to build their own.
This isn’t the first time we’ve seen USB-C powering a small reflow plate. Of course, if you make your PCBs self heating, you can sidestep all that entirely.
