Sysadmin sank IBM mainframe by going one VM too deep

Re: VM/CMS

3270 used coax. 5250 (for AS/400) used twinax. I do not believe any 3270 used twinax. Just sayin'.

Back to the VM part of the story

Jeez. This happened in like 1975. And is the result of someone being an idiot – you don’t do testing in a VM with privileges, for reasons exactly like this.

Plus modern z/VM systems let you (optionally but trivially) specify in the configuration that you have to tell it “shutdown systemname” for exactly this reason. The only reason you would NOT have that option set is if (a) you’re an idiot or (b) because you have some automation that doesn’t specify the system name and you’re too lazy to fix it (which is sort of (a) redux).

Typical Reg article: a germ of truth, wildly distorted. I am disappoint. But not surprised.

Re: Email = Text

You mean like Outlook autopreview, that's been there forever? Or something else?
