API in programming languages is totally stupid because they do not capture order. - Joe Armstrong

People keep telling me this, "you’ve got to upgrade your operating system". Then they say, "Well, that’s because of security things." I don’t really have much confidence in them. If they said we have to change it once every 20 years, I could believe that it was reliable, but telling me that I have to change it once every six weeks is crazy.

Don't be deluded into thinking that is sort of ultimately fault tolerant. You can only provision it for the faulty things that might happen and then for a large class of things it could happen.

I have a problem with categorization problem because I cannot say this thing got to be in that module or that class.
