Readit NewsI'm working on porting a foxpro database from 1988 that's running an active business which I won't talk about much before it's done, and have actually encountered in Costa Rica an auto parts shop in one of the sketchiest parts of the capital city of this country with a green on black phosphor screen running what looked like dBase III for what they were doing on old IBM PCs.
It's pretty crazy what's out there still. I think the one everyone here is familiar with but might not know is really ancient is the travel booking systems for your plane tickets and accommodations, dating back to the 1960s:
Karsten Nohl - Where in the World Is Carmen Sandiego? (33c3) [1]
When we modernized all desktops in the office, I set up Win2k in Qemu on each of them, which loaded the FoxPro thing from a shared network mount. I'm just realizing 19-year-old me never checked if FoxPro supported simultaneous access. It surely did, at least I hope so :-)
edit: However, 19-year-old me was smart enough NOT to touch that Solaris or whatever-it-was server hosting the FoxPro thing.
Market prices on the other hand have exploded this year, $50 per address isn't uncommon anymore.
OpenWrt's build system has a method of building rootfs ext4 and squashfs images without any root, it's somewhere in that large Makefile mess.

And of course AWS Fargate and Lambda use this tech under the hood transparently, so that's always an option if you don't want to host and operate it yourself.
