I know we're getting off topic, but I keep shoving it that way, cause I'm 'done' with the original topic.
I loved FreeBSD. It could do anything, but wouldn't do a single thing until you told it to. Which meant you had to learn it. And once you did, you KNEW a lot of stuff and had the power to do anything. The more we've made computers easier to use, the more useless they become in some ways. We don't take the time to unleash their power.
Two of my kids were interested in "computers" and vaguely talked about "computer" careers. And while they messed around with stuff like Minecraft 'servers' or whatever they weren't digging in like I did. I gave them each a NUC and permission to do anything they wanted with it, as long as it was running some form of Linux. My theory is, if you know Linux coming out of high school, you're employable. They didn't do jack with 'em and have moved on. Although one kid is doing tech support. The other is gonna make a fortune as an actuary.
I did use those NUCs on and off until they got lost. It was handy having a Linux box off site to use real tools to troubleshoot connectivity or DNS or something. Last time I used anything like it, I fired up Ubuntu on a Raspberry Pi so I could invoice a customer who ordered a crapton of product and needed like 300 different invoices. No way was I gonna sort all that data in Excel (well, LibreOffice Calc). 5 minutes to write a shell script and it was done with a punch of a button.
Well, 20 minutes. Because I couldn't get Emacs running and I had to look up how to do anything with Vi.
I know Emacs was 'eighty meg and constantly swapping', but man it was nifty for shell scripting. Vi? I refused to use it back in the day. You want to do something as simple as save your file? Alt>shift>capital P>right shift>lowercase O>knit a sweater>page down>function 7>spin around three times>enter.
If you do get one fired up, I'll dig out a Pi and we can link up and have an online throwdown with Xconq.
