I'd love to see a video of someone downloading to DASD, connecting to the HMC, setting the LPAR and installing. Or the complete process in Z/VM, or in a container. It would be so valuable to teams like mine that are stretched but have noobs. The experienced people don't have the cycles to hold their hands.
The ultimate use for an AI compiler code based OS. ASM function based interpreter in language pick your own style compiled back to ASM for source and then to Machine code, running in a hypertext container. I call it reOS, reverse engineerable OS. Of course It would help if the compilers were more complete with full code description in the asm output. you could choose what functions to compile and what ones to access machine code source functionality both options would be viable for every function.
Good point! I haven't written such code, but if it's text data, I would start by normalizing the data to a common code page (like UTF-16 if writing in Java). Of course, there may be exceptions like code points that don't exist in one. Searching on Stack Overflow and Wikipedia cited some considerations, e.g.: en.wikipedia.org/wiki/EBCDIC#Compatibility_with_ASCII To our mainframe / Linux experts, please feel free to correct me if I got it wrong.
One of the complications and slowdowns in Linux implementations is the virtualization model. In the i Series I found a natural home for JAVA due to the Single Level Storage developed by Dr. Frank Fortis. Security was tighter because of the object model implementation. There was no need for processes to bind and resolve every time they were executed. Is there anything like this in the Z architecture? I'm retired now and simply curious to see if this has evolved. I was kind of a problem for Rochester for implementing DB2 and JAVA before others saw the potential and were still running AS400s in s36 mode and s38 RPG machines. I latched on to the server models and replaced many a S/3xx with the power and simplicity of what became the i series.
We've experimented with long-form series, e.g., the Cybersecurity Architecture series with Jeff Crume. We're evaluating other topics. In the meantime, it's worth checking out skillsbuild.org or www.coursera.org/search?query=linux
Here's the list of certified platforms: www.ibm.com/support/pages/node/6191619 -- be sure to check it beforehand as the versions may change in the future.
Another technical one from IBM. Love these videos.
Excellent! If there are specific topics you'd like to hear more about, please let us know.

Thank you for a great video, Elizabeth!👍
I would love to see some videos about IBM i on here next - especially if they were from Liz!

Excellent video
IBM LinuxONE Community Cloud provides a free basic instances of the powerful s390x system.
One issue is EBCDIC -vs- ASCII. when you port data from non-mainframe to mainframe, HASHing will result in different answers.

EBCDIC and ASCII are in the hardware?
Linux is everywhere, so true.
That's no joke! Sure, there are lots of variants, but if you know one, you can easily move between them without issue.
Great explanation...

That smile is precious tho
SCSI (ASCII) devices have been attaching to z hardware and its predecessors since the 1990s.
Informative video. Could you please make videos teaching Linux from scratch to advance?
Thanks

How long does it take to compile Linux on mainframe vs a 16 core Intel/AMD server?
Thanks ❤
I like the 😀😀mainframe too.
My favorite linux version is pop!_os
120 days to try it out on a VM, nice...
can IBM be held accountable for providing all the neccesary drivers for Linux?
