If you are nostalgic for BeOS, then the elevator pitch is, “It’s Be, only on modern hardware and more software support.”

If you are unfamiliar with BeOS, the pitch is: “Imagine an extremely lightweight desktop is with all of the things you would expect in a modern environment with none of the legacy. In an alternative universe, BeOS would have become OSX.”

There are so many things that Be did right from the very beginning that other OSs have adopted, but never as cleanly as Be did it.

For example, its file system. Most people don’t really notice or care about the file system, they all have directorys and hold files, maybe with permissions. BeFS does that as well, of course, but so much more. The entire file system acts as a database, so you can easily perform fast queries on it. You can also create virtual directories that are the result of those queries.

You want a “folder” that contains every markdown file created after 2020 between 20 and 1000kb in size? Bam, instantly done and live updated whenever something accesses it. The files aren’t actually copied there, just appear there to normal tools, almost like soft links.

BeFS also supports a resource fork system that it calls attributes. These can also be queried using the same database like tools as the rest of the system. File typing is done this way, every file gets a MIME type attribute and there is a daemon that sniffs them when a new file is downloaded or copied over.

Even more, this allows some crazy things like plain text files that have font, color and other formatting elements because all that is stored as an attribute.

Or their contact information app, which stores every person as a zero length file with details as attributes. You can create a virtual folder of all your contacts that meet a certain criteria and have other applications use that folder for whatever.

Or the email app which stores each email as a file, and adds the basic metadata like to, from, subject, read, etc as attributes. Then you can have different virtual folders based on those. This also means that the basic file system browser is the default way to view email, because it supports all the attribute viewing, queries and such you would need. Or you can do it all from the command line using either basic cli tools or some slightly specialized ones.

Combining attributes and virtual directories makes for a fantastic media library system, all built into the os for free. Imagine a directory that contains “Every metal song I have, from 1989 to 1993, that I haven’t played in three weeks” or whatever else you want.

Back when people used files and all applications were local first, this was probably much more exciting, but it’s still pretty cool.
