Containers are over hyped. They are so stupid for home use. People put init systems in containers, then run the entire pile of shit in Docker as root, and talk to me about security and resource isolation. And then all these shit Alpine containers with that MUSL joke. You really can’t take any of it seriously anymore. These people want Windows or a mobile phone.
Flatpack is using OCI so they can publish their shit on any registry. Just another way to pollute an existing ecosystem with garbage nobody really needs. Easing the installation of crap onto your system is not a goal worth pursuing
“Micro chips” cost almost nothing in bulk. They are like a barcode sticker, but sub-surface. Even the scanners are affordable. Plugs right into USB and emulates a keyboard that sends key strokes for the chip ID. Full-size Parmigiano wheel can cost a pretty penny.
