N itself is simply a revolutionary new way of understanding the behaviour of numbers. Just as Albert Einstein's general relativity theory observed that space was not an absolute but depended on the observer's movement in time, and that time was not an absolute, but depended on the observer's movement in space, so it is now realized that numbers are not absolute, but depend on the observer's movement in restaurants.


Question


Bistromathics

Y contains four "consciousness-raising" messages:

• Atheists can be happy, balanced, moral, and intellectually fulfilled.

• Natural selection and similar scientific theories are superior to a "God hypothesis”

• Children should not be labeled by their parents' religion

• Atheists should be proud, not apologetic, because atheism is evidence of a healthy, independent mind

Which “unusual” device did this system use?


Question

Question


X editing retains each permutation of typed

keys. This creates a path in the decision

tree which unambiguously identifies any

command.

Y commands are key combinations for

which modifier keys are held down while

other keys are pressed; a command gets

executed once completely typed. This still

forms a decision tree of commands, but not

one of individual keystrokes.

Historically, X is a smaller and faster

program, with a more limited capacity for

customization.

Y takes longer to start up and requires more

memory. However, it is highly customizable

and includes a large number of features, as

it is essentially an execution environment.

X uses distinct editing modes Y uses metakey chords

X was originally exclusively used inside of a

text-mode console, offering no graphical

user interface (GUI)

Y, while also initially designed for use on a

console, grew a GUI fairly early on.

Identify X and Y


Question
