I'll take a stab at your last question. Imagine a world without computers, without monitors where you had photographic prints and pretty lousy resolution television pictures. For a relatively small amount of money you could purchase a fold up screen and a projector and blow up your photos to 3' x 4' or larger. They were ubiquitous. Often you just had to show up for a business presentation with your tray of slide and you were good to go. Everyone had projectors and screens on site. They brought terror into homes all across America as the dreaded invocation was heard. "We'll fix some snacks and you can see slides of our trip across the Rockies and from San Diego to Vancouver with two of the cutest little poodles in the world!"

Error Messages Written By Devs (MS Office)In the days before computers and proportional spaced typewriters it was the convention to leave two spaces after a period. This was to mimic the practice that typesetters used of leaving a bigger space after a period than between words. SO literally millions of people learned this and as they say, "Old habits die hard."

Functional ProgrammingDeterministic function always return the same value from the same input. That is not the same as a function having no side effects.

Espresso Defcaf?Coffee has 95 mg/8 oz of caffeine. Espresso has 64 mg/1 oz. So in principle you get more caffeine from regular coffee than espresso. But your real question is why decaf. Some people like the taste of coffee but not the side effects from the caffeine. Some people have regular coffee in the morning and decaf in the afternoon. Some people add cream and/or sugar so even a cu of decaf is still a sweet creamy treat. Then there was my Dad who when asked, "Regular of decaf?" He would respond, "Either."

Functional ProgrammingFrom Wikipedia: In computer science, functional programming is a programming paradigm—a style of building the structure and elements of computer programs—that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. It is a declarative programming paradigm in that programming is done with expressions or declarations instead of statements. Functional code is idempotent: a function's return value depends only on its arguments, so calling a function with the same value for an argument always produces the same result. This is in contrast to imperative programming where, in addition to a function's arguments, global program state can affect a function's resulting value. Eliminating side effects, that is, changes in state that do not depend on the function inputs, can make understanding a program easier, which is one of the key motivations for the development of functional programming. Fortran and C are not functional programming languages. Having functions does not make a language functional. And one of the reasons for renewed interest in functional languages is they have certain advantages when trying to parallelize programs.

When I say "goto", my parrot says "Spaghetti Code"Edsger Dijkstra (March 1968). "Go To Statement Considered Harmful". Communications of the ACM (PDF). 11 (3): 147–148. doi:10.1145/362929.362947. The unbridled use of the go to statement has as an immediate consequence that it becomes terribly hard to find a meaningful set of coordinates in which to describe the process progress. ... The go to statement as it stands is just too primitive, it is too much an invitation to make a mess of one's program.

Self-Driving Cars: A Coming Congestion Disaster?People buy and drive their own cars (especially second cars) to get to work because it appears to be the best alternative. If I take all the costs of owning that second car and can spend less money on a car that someone else maintains and that allows me to read, sleep, work, etc. for the 90+ minutes I spend commuting I believe that would become the best alternative. Certainly not for everyone but for the majority of people.

Self-Driving Cars: A Coming Congestion Disaster?I must have missed something. The original post was about congestion. If you live where you indicated I'm guessing congestion might not be an issue. And I didn't say you could call up and get a car in a minute. Maybe you would order in advance. You know there are lots of people who don't have cars and they have to use buses, taxi and trains to get around (or walk). To me the central advantage is over the current system. Millions of people get in their cars and drive to work at the same time because mass transit doesn't serve them (too expensive), they need to drive somewhere once they are at work, they don't like being around other people, etc. Once they get there they have to do something with their car. Rush "hour" actually lasts a long time. So to me one car could bring one (or more people to work) and then go and get someone else. They could go somewhere else to park if need be. My point is that millions of commuter (but not necessarily all) cold benefit from this type of service.
