>> -My favorite memory from CS50 was when I went to Puzzle Day.

>> -Probably just the time spent working on problem sets

with my friends and people who wold eventually become my blockmates.

>> -My best memory from CS50 is the Hackathon.

>> -My favorite memory is when I was on stage and I played the prestigious role

of a node [? in the Linked ?] [? List. ?]

>> -When we all got free Dropbox space and David was like, look under your seats.

>> -My advice for any incoming student would

be to really work on P-sets with friends.

>> -Office hours is very much your friend.

>> -Make the most of your experience and meet as many people as you can.

-I think the biggest thing is to take advantage of all the resources

>> -Go to office hours early in the week.

-Make sure you find a great group of people to work on P-sets with.

You can have a lot of fun and get work done together.

>> -Write things on paper before you ever touch your computer.

>> -CS50 is really great at providing ways to get help.

It's easy not to do, but you've got to do it, I think.

>> -I would say really be mentally prepared because you're going to love it.

>> DAVID J. MALAN: So this is CS50 and this is the end of Week 0.

And that was just some of CS50's staff who

await you not only in sections and office hours, but,

also, this coming weekend at CS50 Puzzle Day.

Which, again, is not all about programming.

Indeed, it's expected that you won't have to program anything,

but rather solve problems using wits and friends alongside you.

>> We will be joined by some of our friends at Facebook--

if you register here-- who for the past several years,

have actually been writing these challenges with us.

And so, they will be the ones ultimately running Puzzle Day.

And so, you will be challenged with precisely the kinds of things

and problems that folks at Facebook like to think about.

>> Now a word on a couple of staff in particular.

This here is Ansel Duff, who is actually one

of the co-authors of these binary bulbs that we saw on Wednesday,

Ansel Duff was also a former freshman advisee of mine 3 years ago

He's gone on to do engineering sciences and more.

Now, his picture here is actually Ansel 3 years ago at the CS50 Hackathon

when he borrowed one of our balloons, stuck it to his laptop,

and, for the next 12 some odd hours, focused on his final project,

taking breaks only to open bags of candy at the Hackathon.

>> But he went on more recently to spend this past summer with us,

since CS50 for its staff, and now students this semester,

And in a nutshell a 3D printers is a device that looks quite like this.

You fill it with a plastic spool that is melted down by the device

and you build things literally from nothing.

Much like an inkjet printer, you start spitting out little dots of plastic

that form together to form whole objects.

And so Ansel for instance, earlier this summer, has an iPhone 5

and decided he really wanted to prop it up on his desk.

But he didn't want to go out and buy something

from the Apple store or the like, so he sat down and started drawing something.

He took a few measurements as to how thick

and how wide his iPhone was, he drew this image here,

he decided that he wanted to have a 75 degree tilt

as it was staring at him on his desk there.

He then turned this, using software, into a 3D CAD model

that looked a little something like this.

And then he proceeded, ultimately, to actually create it.

So in fact, if any of you here, perhaps in a row that I can throw to, have

an-- there we have folks with iPhone 5 , and here we have two more.

>> Now, not to be outdone, CS50's own Cheng Gong also set out this summer
