Comment "Authority" is not how Interpol works (Score 3, Informative) 10

Interpol has no direct power. It's a voluntary association of law enforcement agencies among many countries. An Interpol red notice requests that other countries who see this person arrest them for extradition.

It also doesn't force other countries to do anything. Russia and Turkey, and I'm sure others, have both issued Red Notices for political dissidents, and other countries have ignored them and/or complained.

Comment Apple has the advantage of JITting (Score 2, Informative) 74

iOS is a full W^X OS, and applications are not allowed to make any page of memory executable that has not been signed by Apple. However, Safari is specifically given permission to use JIT. Even if Apple were forced to allow browser developers to use their own engines, Safari would still perform better, because of runtime code generation.

Comment Also, you don't need imaginary numbers (Score 3, Insightful) 179

Let's say that you have some physical quantity that is described best as a pair of numbers <a,b>. You find that there are two reactions between pairs of these quantities.

One reaction between quantities <a,b> and <c,d> results in <a+c, b+d>.

The other reaction results in <ac-bd, ad+bc>.

Call the first one "addition" and the second one "multiplication" and you have an equivalent mathematical description of complex numbers without a concept of "imaginary" involved. (Instead of the square root of -1, you simply have the property that <0,1> * <0,1> = <-1,0>.)
