More speculation...

... in the vein of this.

Jesus says in Mark 11:23I tell you the truth. Anyone may say to this hill, "Go and jump into the sea." He must not doubt in his heart, but he must believe that he will have the things he asks for and he will have them.

What if Jesus didn't mean "if you have faith, I will move the hill (mountain) for you", but "if you have faith, the hill will move because the Universe was built to respond to human volition"? We know that the human body responds to human will sometimes (placebo effect); there's a speculative part of physics (quantum physics) that has as a basic tenet that human observation can influence the outcome of physical processes.

Why the need for "unwavering" faith, then? Well, the Universe is probably a simple mechanism, if you're not very sure of what you want it cannot respond to your will. Maybe there's a "faith threshold" that triggers the mechanism; or maybe there's a required rati…

On extending DBMSes

Problem: you have some data for your company. The data has to be accessed from multiple applications (think accounting, personnel, sales and so on). How do you make sure business rules are obeyed - because if there's a bug in even one application, it will ruin the data and thus every other application.

I agree with pretty much everything Fabian Pascal has to say about relational databases. The RDB *is* the place where data should live, and ideally it should be the place for business logic too - because business logic is about data.

However, there are a few problems with this - mainly because of a lack in implementation, not in the theory of the relational database:

No existing DBMS (Database Management System) - the actual implementation of the relational database theory - can support thousands of concurrent users, let alone millions.
It is hard to do user management / authentication in the same database as your business data - in fact, it might be a good idea to have separate databas…
