Messages and its Gerund: Reliable Messaging on the Cheap

Mark continues on messages and files with a crucial observation...

Filesystems, after all, are one of the few things that define and hold together operating systems; they allow for unintended uses of data. If you expose everything through a specialized API, everyone who comes into contact with the system ? developers, administrators, and users ? has to learn a new means of accessing it.

True, but I would generalize this to any kind of database. A filesystem is simply one kind of database. In its typical form, it is outmoded. But Mark continues...

Put another way, I can’t think of any good reason why you wouldn’t want to expose persistent state as a file. that doesn’t mean that there can’t be other interfaces, but why lock it up in them?

P.S. Sean, I’m not sure specialised RPOST/RPUT methods are necessary; I think it can be done with a pattern, or maybe a few extra headers.

Mark's click-submit-only-once pattern is thought provoking.
