For a([x,y,z],k) where x,y,z,k are all lists, it gives [x&k, y&k, z&k], vectorizing each list as I stated above.
So a([[0,1,2,3,3,2,1,0],[0,1,2,3],[0,2],[0,3]],[0,1,2,3]) gives [[0,1,2,3,3,2,1,0]a[0,1,2,3], [0,1,2,3]a[0,1,2,3], [0,2]a[0,1,2,3], [0,3]a[0,1,2,3]]).
Which is [[0,1,2,3,3,2,1,0],[0,1,2,3],[0,1,2,3],[0,1,2,3]]
(See also this question, which is similar, but talks about the situation where the language is normally stored on disk with one command per byte.)
This question originally came up in connection with 7, but might be relevant to other languages.
In 7, each command is only three bits long (it only...

It seems to be the consensus that it is acceptable in Brain-Flak to decompose a list into a series of arguments when taking input.
For example if you are to take the list [2,5,6] as input you may run the following Brain-Flak

The same is also true of output, if yo...
Jetblue's password requirements specify that, among other stringent requirements:
Cannot contain a Q or Z
I can't fathom a logical reason for this, unless it were say, extremely common for the left side of keyboards to break, but then you wouldn't allow 'A' either :)
What would be the reas...
