According to a newspaper report about Chelsea's purchase of an apartment in New York a few years back,Initially there was just one full-time doorman to stand watch outside. But one can assume that if Hillary becomes President, there will be more than just a "doorman" to mind the store. Or will she demonstrate her determination to remove barriers by demanding that security agents guarding the site be withdrawn and the doormen be dismissed?I think you know the answer.And I think, on the basis of the information provided here, you will share my belief that Hillary Clinton is a flaming hypocrite.Related posts: In the recent years, programming language design has gone through a renaissance primarily due to two factors: (1) Multicores became standard in consumer PCs.

With this article, I try to collect the most important mistakes that every serious programming language designer should avoid. I will ignore opinionated questions like dynamic vs static typing. Also, I will omit mistakes that can be fixed without major pain. For example, adding parametric types later on seems to be possible. Sun added Generics to Java eight years after the 1.0 release.

0. Null pointers

A reference to an object may be a null pointer in all popular languages, which leads to runtime errors. C.A.R. Hoare recently took on responsibility for this "invention", though a lot of other designers are to blame as well.

I call it my billion-dollar mistake. It was the invention of the null reference in 1965. [...] More recent programming languages like Spec# have introduced declarations for non-null references. This is the solution, which I rejected in 1965. - C.A.R. Hoare

Languages like C/C++ just crash with a segmentation fault on dereferencing a null pointer. Java, Python and other languages throw a NullPointerException, but the problem is that this RuntimeException may be thrown at nearly every statement. A static type system can be used to declare references, which are guaranteed not
