2)

Etymology
When you enter or 'sign on to' a computer, your activity is recorded in an electronic 'log file'. A 'log' is a record of events, like a diary, and 'on' refers to entering the file. Since computers became popular in the 1970s, 'log on', 'log in', and 'login' have become very common terms.
===
luck of the draw
According to fate or chance.
Example
1) everyone else's computer works just fine, but mine is broken. I guess that's the luck of the draw.
Etymology
When playing cards, you 'draw a hand', which means that you get a random set of cards. The cards that are dealt are called 'the draw'. So the 'luck of the draw' refers to the good or bad results produced by a random process.
Synonyms
