The Nineteenth Byte

In speech, this is merely a relaxation of pronunciation - should have becomes should've, must have becomes must've. This relaxed pronunciation is fine. However, the contracted have (i.e. -ve) should not be written as of. Of sounds similar to -ve, so many people erroneously think should of and ...

@LegionMammal978 You can't add a scalar and a matrix though

Fatalize

should be, should do, should say, etc. => should HAVE

how is that difficult

to get

quartata

It isn't. But the way should've is pronounced sounds like should of, as a result regional things emerge where people write it like that in informal contexts

Downgoat

@Fatalize Got it. I'll be sure to run every chat message here through Grammarly.

Downgoat

@Bálint Instead of "shouldn't of", which sounds nearly identical to "shouldn't have", I'm asking if Fatalize would prefer I use, "shouldn't've", which is very informal English, used mostly by hillbillies, but valid.

@Bálint I don't think so. At least all the trains I considered were quite slow. Most of their track systems aren't built for great speeds.

Should the result of nil being cast to a string be Nil or nil?

nile

TùxCräftîñg

But sometime, the name is capitalized, like with C#: true => True for example, so Nil is also enviseageable

Downgoat

constants like true are lowercase so I'll go with nil

nil is shorter

No they form a basis of the vector space of matrices

They are basically like the unit vectors (1,0,0), (0,1,0), (0,0,1) in the three dimensional space.

Attitude indicator

An attitude indicator (AI), also known as gyro horizon or artificial horizon or attitude director indicator (ADI, when it has a Flight Director), is an instrument used in an aircraft to inform the pilot of the orientation of the aircraft relative to Earth's horizon. It indicates pitch (fore and aft tilt) and bank (side to side tilt) and is a primary instrument for flight in instrument meteorological conditions. Attitude indicators are also used on manned spacecraft, where they indicate the craft's yaw angle (nose left or right) as well as pitch and roll, relative to a fixed-space inertial reference...
