We Jarvis then Ada'd 3 portals within standing distance of each other. With the heatsink and multi-hack mods we put on, we were able to hack what we figured about 22 times on each portal in about 30-35 minutes. We didn't keep very good stats or time..
A few of us had to purge some inventory because it was so successful!
So this flea with no size or mass, we'll call him Fleaba, sits in middle of circular table of radius 1 m (see below).
Fleaba takes a series of jumps towards the edge of the table. On the first jump Fleaba jumps half way to the edge of the table. On each succeeding jump Fleaba jumps half the remaining distance and so on. When will Fleaba reach the edge?
