What an amazing read on general Unix history!

Reminds me that people used to get email very slowly via dial-up using UUCP. Email might take several hours to deliver because of the hops involved needed to wait for the schedules of each dialing system in the path. RIP !paths.

In the late 90's, I also discovered IBM's AIX with the web browser package(s) installed phoned home unknown telemetry to Big Blue because it was that traffic that forced an ISDN dial-on demand IPv4 connection to come alive when no one else was in the office and no cron jobs were running, jacking up our phone and ISP bills.

And now Android uses mksh, a free Korn clone.
