   professor gave us a stupid dumb shell exercise that i wasnt doing because its stupid . then after one hour of time , he shares the solution on the projector because many students (4th year astrophysics students) couldn’t do it . shocked , without looking at his solution i type my own in around 70 seconds

   #!/bin/sh echo 'input your guess: 0 for head, 1 for tails.' read guess random_number="$(cat -v /dev/urandom | sed 'q' | wc -w)" if [ $((${random_number} % 2)) = $guess ]; then echo 'good guess!' else echo 'wrong :/' fi

   i guess at least my classmates arent gpt-brained ? at least for coding ? yay ????

     @fiore i mean..
     
     if your system has /dev/urandom, it likely has bash too.

     holy fuck.. you could've just used `$(($RANDOM % 2))` instead of that garbage.

     and like dont get me wrong . i suck at writing shell scripts , the ones i write are usually clunky and break in weird ways . but like bro what are you doing wasting a whole hour of an high performance computing class on how to write a heads or tails bash script 😭
