At 15.00 we will meet to share with each other what has happened, what was discovered, what didn't work, and what will be next. Which is also a way to create a partial guide/documentation of the discussions and materials. These following are the different angles, please take the time to look at the points before/during lunch.
How to divide in 4 groups:
Dividing into groups using modulo
Take note of the last bit of your ip address (ie. in 10.9.8.7 it would mean 7 )
In terminal run bc (the arbitrary precision calculator):
$ bcthen calculate the modulo ( the rest in a division ) of the last bit your ip address divided by 4!
$ 7 % 4
You are in group 3!
Generating one random number between 0 and 4:
$ shuf -i 0-4 -n 1
OSX / OpenBSD:
$ jot -r 1 0 4
Method 3: classroom method
number each others in sequence (0,1,2,3) in a circle
