       Monetary-gating is no more effective than dynamic reputation assessment, but it sure is a lot more exclusionary.Pretty much the first red flag with Urbit in isolation (it gets worse when one reads on the community & everything else; predictably a lot of its issues, including the monetary-gating, flow naturally from the creator's ideas).Its documentation makes some very vague promises but it doesn't really seem to do much for something that calls itself an "overlay OS".

       For an actually serious overlay OS/desktop, take a look at ArcanFE/Durden instead.

       @lispi314 I would also consider inferno, chrysalisp, medley interlisp, gnu emacs, self, squeak, etc. to be valid foss entrants in this category of "overlay os" to a greater or lesser extent

       @lispi314 I think the earlier you go the fuzzier the concept gets and the more it just breaks down into the general morass of macro languages/pcode runtimes.  Like does Framework count as an overlay OS?  UCSD Pascal chainloaded from DOS?  MacMINIX?  MachTen?  lol.

       I think the earlier you go the fuzzier the concept gets and the more it just breaks down into the general morass of macro languages/compatibility layers/pcode runtimes.@allison  this is so incredibly true. And this is also kind-of why I think Andrew Tanenbaum ultimately may have been right and Linus Torvalds may have been wrong, in that infamous debate they had over operating system architecture. Probably a microkernel architecture is the best way to go for an actual operating system.On The microkernel establishes various userland environments, like QEmu, FreeBSD Jails, various OS compatibility layers, and so on.Once you have the microkernel, then you can have the “seat,” which manages user sessions (maybe the “session layer” by the OSI model), which is something like Arcan. This establishes a consistent API for managing high-throughput devices (especially graphics cards), and IPC mechanisms.On top of the session layer, you have the application layer (the “app platform”), and this for things like WebKit, Java, .NET, Android ART/Dalvik, Squeak, Glamourous Toolkit, Emacs, Medley, Gnome, KDE Plasma, and so on.@lispi314 #tech #software #SoftwareArchitecture #OperatingSystems #Microkernel
