Getting Started
Alright, here we go again!
Log into cs50.io and execute
update50
within a terminal window to make sure your workspace is up-to-date.
Next, execute
mkdir ~/workspace/pset4/
at your prompt in order to make a directory called pset4
in your workspace
directory.
Now execute
cd ~/workspace/pset4/
and your prompt should resemble the below.
~/workspace/pset4/ $
Fabulous Prize
And now the real fun begins. You are hereby challenged to find as many of the computer scientists featured in the photos that you recovered for Recover as possible. To prove that you found someone, take a photo of yourself posing (anywhere) with the computer scientist (in such a way that he or she is aware of the photo and not just in the background). If a photo contains multiple computer scientists, you’re welcome to pose with each of them separately. Upload your photos (i.e., the photos you took, not the ones that you recovered) to a non-private album somewhere that supports bulk downloads (e.g., Dropbox, Imgur, etc.), then email your album’s URL to selfies@cs50.net by noon on Mon 10/3! We’ll add your photos to a public gallery (unless you request otherwise).
Whoever finds and photographs the most computer scientists (and, in the event of a tie, submits first) shall be rewarded with a fabulous prize.
