This is a preview of things to come in Serenum Release 5. A new update for my OS that I am relentlessly crunching on to complete.https://samhsmith.com/serenum/
Not my video. Just felt it fits here for more discussion. Personally I do like the idea of more/better sandboxing for apps.
Reminds me a little of the old Jonathan Shapiro research OSes (Coyotos, EROS, CapROS), though toned down a little bit.
The EROS family was about eliminating the filesystem entirely at the OS level since you can simulate files with capabilities anyway.
Serenum seems to be toning that down a little and effectively having file- or directory-level capabilities, which I think is sensible if you’re going to have a capability-based OS, since they end up being a bit more user-visible as an OS.
He’s got the same problem every research OS has: zero software.
He’s probably smart to ditch the idea of hardware entirely and just fix on one hardware platform.
I wish him luck selling his computer systems, but I doubt he’s going to do very well.
What would a customer do with one of these?
Edit files?
And then…edit them again?
I guess you can show off how inconvenient it is to edit things due to its security.
I just mean it’s a bit optimistic to try and fund this by selling it.
I understand he doesn’t have a research grant, but it’s clearly just a research OS.
