On z-architecture, only machine instructions that change or set the TOD
clock are privileged. The STCK and STCKE instructions only provide
read-only access to the TOD clock and are not privileged or restricted
by hardware, but they are not taught in programming texts either.

It's all about trust.
SO glad you posted, and esp that you found the announcement.
(A little concerned, though, that their primary web interface doesn't
have an alert.)
I would have panicked.
Interesting that handling of this SSH key: #1 is manual effort for the
clients, and #2 is *minimal*
STARTIO seemed easier than all the setup for the EXCP.

Never gotten that error with GitHub before, but gotten it many times for

The error message usually tells which line in your .ssh/known_hosts file

A load module has the same format regardless of the language. The relevant

It's not that difficult to read them yourself. Reading a program object,
however, requires information that IBM charges for.
