[MUSIC]. 
Well, we've come to the end of the 
course. 
And we'd really like to thank you all for 
having made it this far with us. 
this has been an incredible learning 
experience for us on how to deliver this 
kind of material. 
Over Coursera and over the over the video 
format and Distance Learning. 
And we hope that you learned a lot about 
the computer systems we've been talking 
about as well. 
the course might, might not, this course 
format may not have been as new to some 
of you. 
you might have done other courses like 
this before. 
we'd be very interested to hear about 
your experience and, and how, what you 
thought of how we ran this. 
for us, it's brand new, so we have a lot 
more to learn than you do about that 
aspect. 
and 
Well, thank you very much for putting up 
with us all of the way through. 
 >> And well. 
We also hope that you, you learned how, 
your programs run in a computer system. 
Have a better idea how, how computers 
work. 
And we hope that, this, course has 
spurred your interest in learning more 
about programming in C. 
And learning more about, and, and other 
programming languages. 
And in learning more about how operating 
systems work and computer architecture 
and, and so on. 
We also hope that the, the labs and 
assignments were more rewarding than 
frustrating. 
We know some of them were quite time 
intensive, but we really hope that they 
gave you a much better understanding of 
how things work. 
So in case that you noticed that Gaitan 
and I wore the same shirt throughout the 
entire course. 
So and as a gift for you at the end of 
the course, we decided to show you how we 
normally dress. 
 >> So as you can see we like dressing 
pretty differently. 
Luis is very formal, loves dressing up. 
 >> And this is his regalia from the 
University of Illinois. 
And I'm a little less formal. 
 >> Right as you can see guys, Gaitan 
really likes football. 
But most importantly you see that his 
number is 32, which is a power of 2. 
Really to, you know, as homage to his 
Computer Science devoted life. 
[LAUGH] And I'm sure you saw this number 
32 in the course a lot. 
And you're going to continue seeing the 
number 32, in doing Computer Science. 
 >> Well, so, again we'd like to thank 
you for taking the course with us. 
And we hope it was valuable for you, it 
certainly was for us. 
And we look forward to maybe seeing you 
again sometime soon. 
so from Seattle, take care, and keep on 
programming. 
 >> Thank you very much, keep on 
programming.
