        to unpack this a bit, an operating system which sees more structure than arbitrary byte-array files and arbitrary machine-code programs. Browsers actually are along these lines

        strangely, I'm also interested in the opposite way: an OS that _doesn't_ understand what's going on, i.e. "exterminate all operating system abstractions" go below files & expose raw disk blocks to applications as in Exokernel, so e.g. a DB doesn't need to go through a kernel FS

        there is probably a cool take here around 'legibility' of applications to the operating system and the constraints which that imposes

        Hot take: Could start with the file system, which really should be a full database + blob store. No application should have access to any simpler file primitive

        That's what was done with the BeOS file system by Be, an Apple spinoff https://en.wikipedia.org/wiki/Be_File_System …

        I think it's a perennial dream -- someone brought up the IBM mainframe OS which apparently had structured files and joins, and there was WinFS in Longhorn https://en.wikipedia.org/wiki/WinFS

        OS/400 treats files like databases, and lets you create logical files that are the result of joins on physical files https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_72/dbp/rbafocrlff.htm …

        huh! reminds me of the Plan 9 union mount ('PATH' in Plan 9 just being whatever directories are union-mounted to /bin, for example) but for files I need to learn more about mainframes :)

        I did OS/400 administration as a summer job in high school, I had to relearn every OS concept all over again... Another neat thing is that it supports different character encodings down to individual fields within a file, and supports lots of encodings https://www-01.ibm.com/software/globalization/ccsid/ccsid_registered.html …

        "fields within a file" is already a leap for me haha
