factoring 

In encryption systems, very large prime numbers (200 digits long or more) are used to generate other prime numbers. When trying to decode encrypted data it is necessary to find the two original prime numbers.

I use factoring to generate my private encryption key.

Factorio 

A drug that will slowly draw you in and wreak havoc upon your very sanity in an endless quest to automate and perfect your setups. Its mere presence appears to have the power to distort time. Be prepared to lose your soul, mind, and virginity to this game. It will take everything you own and ruin your family and life. But it will be worth it. Because you just hit 1K SPM at 60FPS/UPS

Factorio 

A series of unknown or unforeseen events required to take place in order accomplish a single task. Often causing a great deal f time to pass before accomplishing the original task you set out to do.

"I'll be over in a half hour, I just need to make breakfast"

You realize you dont have any food for breakfast so you need to go to the grocery store.

You can't find your wallet, you remember you left it at your other friends place lastnight.

You get in your car and realize your low on gas so you need to make a stop at the gas station.

You drive to your friends place and pick up your wallet. But they're the type of friend that you kinda have to stick around and chat with for a bit or they get salty.

You drive to the gas station and while paying at the pump, you receive an NSF message. You transfer enough money for your gas and required groceries then fill up your tank.

You arrive at the grocery store and spot your supervisor. Trying desperately to avoid her, she spots you. You're obligated to make small talk.

You head home and put your groceries away and realize you forgot to start the dishwasher.

You pull out a few dishes, start the dishwasher and turn to your sink to start the dishes. You realize you are out of dish soap.

You go back to the grocery store.

You do the dishes by hand.

You cook your breakfast, brew some coffee and sit down to finally relax and eat.

You now have to poop. So you do.

It's been 4 hours trying to accomplish the single task you originally set out to do. Your friend calls and asks what's up? You explain that you had a factorio morning and thought you could complete what you needed to in a half hour but that's not how factorio works.

The Northern areas are felon factories!
