Beating Linux into submission

Or, "All mimsy were the borogoves, And the mome raths outgrabe."

This is a bit of a reach for most but I do "a bit" of advanced computing here and maybe, just maybe a geek or two here could benefit.

I have no idea what Im doing. Almost never have problems and if I do I just reformat the disk and reinstall clean. Havent paid for an OS in over 15 years eff windows and mac

Nice home PC but certainly not enterprise class. What version of Linux are you running? What are you trying to do? When I declare a system variable for the bash shell I use #!/bin/bash wether it is for an account or a system setting which I know works. I am not familiar with #set -o pipefail and need to research that. I am not a programmer but have been working with AIX since about 1992 and various flavors of Linux ( AT&T and System 5 ) for a few decades. I am certainly not the best but I have been around the block a few times.

And I was excited when I was able to add a 4k SRAM S-100 board to my homebrew KIM-1 based computer (a 3X increase)...

For most of the production work a gui is very rarely used - I will take a command line running on a super putty terminal.

Trying to do? I have need of more than a few specialized operating systems natively. So, more than a few virtual machines. This of course gobbles ram like crazy. Then, I'm a tab whore. I have close to 300 tabs open in several different browsers, on several different machines. It's the nature of the work ...

MATLAB Partial Differential Equation Toolbox. Specifically I break stuff in the machine before it's built and destructively tested. Some of the smaller stuff I can do locally. Larger projects get offloaded to a "farm". It's the difference between weeks and hours.

CATIA and Fusion, I have or use those licenses as well. As much as I have an unrealistic distaste for all things M$ I still need the platform on occasion. M$ office products have no near peer as well so...

The only reason there is a "large" (by 10 years past) GPU in the box is I do have need of a browser and when extruding/rendering/modeling, I prefer seconds, rather than minutes or hours.

In the end it's a home toy and built on cast off parts that for me just work. Base arch is a retired HP Z820 The whole point of the post was finding a a way to cram 30T of storage into a ZFS pool without aging years within days.

So I'm just curious, what are you doing with these Linux computers? What are you using them for?
No code talk please, just laymans description.

I use mine for basic home computing, web browsing, file storage of my photos, miscellanious document storage, light photo editing. Personal use no business use though there's plenty of open source software for that too. The latest current operating systems are maintained and free safe and secure so it doesnt make sense for a home user to continue to pay Microsoft or Apple for their operating systems every 2-4yrs plus virus protection services.

Im a very long time Linux user and enthusiast here and I remember when Redhat shipped their software in low-grade recyclable boxes with disks accompanied with a horribly printed manual on cheap recyclable paper. A veteran of the 90s OS Holy Wars and a dyed-in-the-wool Linux Administrator for a couple of fortune 500 and 100 companies.

These days I'm a devops engineer and my daughter is in college for cyber security with Linux being ubiquitous at the Williams compound. I do have a drive for Windows but that is only used for gaming, PUBG mostly.

Cheers!

Used to administer AIX 4.3 and 5.x way back in the day. When in doubt, smit and smitty FTW.

@kopcicle do you check in to the "Linux user net" on the K7RPT linked repeater system on Tuesday nights? Lots of geeking out there. I see you're in Kent. It's also on Echolink. Every Tuesday night at 8:10-9pm

I use Redhat Linux Enterprise Edition today exclusively. I have used FreeBSD, Ubuntu, Rocky and it's predecessor when it was unbranded Redhat. SUSE and several others. I have less than eight years till I hang it up. Not going to miss it
