[TUHS] June 8, 2026 – Vivian Voss – Where Unix Runs Today

[Charles H Sauer (he/him) via TUHS]

I discovered https://vivianvoss.net/blog/where-unix-runs-today yesterday 
and sent the excerpts below to former AIX colleagues and others that 
might be interested. I forwarded that mail to Clem and Heinz this 
morning. Clem replied with a detailed commentary. Clem seemed to agree 
this might be worth posting here to liven things up.

''Open the laptop in front of you. If it is a Mac, you are on certified 
Unix. Hand it to the child next to you, watching cartoons on an iPad — 
also Darwin underneath, the same family. The phone in your pocket: same. 
Walk through any data centre serving European video, and a sizeable 
share of those streams come off appliances running FreeBSD. Pick up a 
games console at the till in any electronics shop, and odds are very 
good it boots a fork of FreeBSD before it ever shows you a menu.
...
''One footnote worth keeping. Apple is certified on UNIX 03, dating from 
2002. Only one product on the planet is certified at the next level — 
UNIX V7 (Single UNIX Specification version 4, POSIX.1-2008): IBM’s AIX 7.
...
''The world’s commercial Unix systems are not all in retirement homes.

''IBM AIX is actively developed. New versions track new IBM POWER 
processors; the public roadmap is clear. AIX 7 is the only operating 
system in the world certified at UNIX V7 (SUSv4) level. Banks, 
insurance, large enterprise back-office: AIX still carries this work, 
and IBM still treats it as core strategy.''
