Tips on making a long DJ set:
Lets say you need to DJ for 7 days straight over a hacker camp
You can subdivide this problem into 7 1 day sets.
That's still pretty hard, lets try again, 49 1/7th of a day sets, that's aproximately 3.5h
Ehh 1/7th is a hard number lets go deeper 1/49th of a day long set. Anyone will tell you 1/24'th of a day is 1h so 1/49 is obviously 1763.265306 seconds
This seems like a reasonable problem to solve but we're mathematicians, we're lazy
7^-3 or 1/343th of a day is roughly 4.2 minutes. Here our problem resolves to a trivial solution, play a single 4 minute long song.
From here we can deduce that John Cage's 4'33" is the most apropriate option due to it's length clearly being stated in it's name.
Therefore by extrapolation we can solve our 7 day DJ problem by playing 4'33" 7^4 or 2401 times in a row.
We will however have to negotiate with the venue to start earlier then planned as our set is slightly over time by a mere 844mins 33 seconds
