This doesn't always work. A friend did massage in a small fishing town in Alaska. As soon as she put on the ocean-waves-breaking-on-a-beach sounds, the massageee would usually bolt upright from the table in a total panic attack. Your mileage may vary!
We actually used it in a semi-production configuration. We had an Apple 8100 sitting in the corner. We needed a machine to FTP all the weather sites every 10 minutes and download current conditions to input into a running near-realtime ocean current model. Kinda like Windy, except this was the mid 1990's.
The code was a custom Perl script written by a programmer that later died with his family on the plane that crashed into the Pentagon on 9/11.
It ran very reliably for weeks, except when somebody would login and run X-windows. Then it would die a horrible death within hours.
One oddity about the version we had, it had to be installed from MacOS (System 7 I believe). Some of the pathnames in the default install were longer than what was allowed in MacOS (256 characters, I think) so not everything would be installed correctly!
I also had an MkLinux machine I used as semi-production machine from ~96-99. I was able to get a Cable Modem in early '96. Back then ISPs only supported single machines directly connected to the modem, so I found an old Power 6100/60, installed MkLinux on it, and used it as a dedicated nat box.
There wasn't free list hosting or chat back then either (ISPs used to charge you to host a listserv!), so I got sendmail, majordomo, and ircd running on it. I even provided pop3 and smtp services for some of them who did not have their own internet accounts. As I recall getting ircd working on the platform was pretty challenging to me as a teenager.
My friends kept in touch using the chat and mail servers on that machine for years.
Just curious, are you the regular "geezer" who stopped posting a couple years ago, and if so why the new account? If not, and just a lurker who finally created an account to comment with, welcome to hn!
