What's the context for "Ring 4" and "Ring 5"? Are these some multitier architecture terms?

- warpech 10y agoI suppose it has to do with https://en.wikipedia.org/wiki/Protection_ring https://en.wikipedia.org/wiki/Protection_ring
- oblio 10y agoI find it kind of a funny that over-engineering lost, same as in OSI versus TCP/IP. 7 layers vs 4, 4 rings available vs 2 rings actually used.
- Elves 10y agoFunny, but the lesson is never learnt until late in life. To paraphrase Aristotle: "Only achieve that which is sufficient". Ironic that Lua was designed to be as simple as possible and no simpler (was that Einstein?) and then it gets layered (laid, layed?) over ponderous systems that it really should be replacing. And finally, complying with the rule of three and layering (pun) upon dijkstra's proposition: "layers should be considered evil". Personally, in software, everything should be compiled to machine code if not already written in it, optimised to remove function calls and loops and at run time ensure that all data fetches control movements use the nearest memory.
