Final grades/summaries are posted on the
server.

Here's the stuff I did in class on Thursday
and Monday. It's a little unfinshed... but you get the ideas.
Thursday, April 10th, 2008
Please show up to class today for evaluations... those that do will
receive extra "Karma" on their grades... Tell your friends.

For those of you that love What if? scenarios, here's a mini
version of the code I'm using for
the grade calculations.
Tuesday, April 8th, 2008
Up-to-date summaries are posted on the server. Here are the stats:
| Max | 97.99 |
| Mean | 72.07 |
| Median | 71.91 |
And here's the results of running this function... What is it good for?
(define (borders log)
(local ((define (skip n log)
(cond [(= n 0) log]
[else (skip (sub1 n) (rest log))]))
(define (doit n log)
(cond [(>= n (length log)) '()]
[else (cons (list-ref log n)
(doit n (skip n log)))])))
(doit (ceiling (/ (length log) 5)) log)))
(check-expect (borders grades)
(list 84.59 72.58 67.48 63.50))

Here's the game lecture code. Add
to it (or at least think about what we should add) for Wednesday.
Sunday, April 6th, 2008
HW 11 may be submitted late at a point reduction of (at least) 15%
depending on when you submit. I will not accept any
HWs later than Wednesday, April 9th @
6:00pm.
If you submitted ontime and feel it will help your grade more
than 15% to resubmit... then you are free to do so, but
the latest submission will be graded and have reductions
applied.
Why the reduction?
- Others in the class have worked hard to submit ontime
- You've had (more than) 2 weeks to complete the assignment
- Assuming you completed HW-8 correctly, this was just a few
simple additions
- The reason the due date is early is because I need to grade
all of them before grades are due.

Note: this only takes into account the first 5

final grade.

There has been a few people sick, and probably recovering from our
midterm and others.
I'm feeling nice ;) so I will leave the submission server open until
after class on Thursday.
Hopefully that will help all of you polish your programs and
you'll all get 100% right?
Also, HW #8 is posted; due the Wednesday after Spring Break. It
shouldn't take you that long, but look it over so you can think
about it in your spare time.

Tonights Lecture Code:
I made a few changes. Look at the function 'dir-append' to see
how I keep the directions from the keyboard in the right order.
Once they're in the correct order, you can make Etch-a-sketch like
drawings

Exam schedule is posted
Here. Accessible from the left menu
as well.

Here's yesterday's lecture
code.
Tuesday, February 5th, 2008
Here's most of yesterday's lecture
code. I quickly implemented a limited frogger last night, so
maybe we'll do that next lecture.
Try to think about how you would do it?
Monday, February 4th, 2008

Here's the broken code from
tonight's lecture. I removed all the magic so everything might make a little more sense.
For a better discussion of vectors see this.
Thursday, January 24th, 2008
Here's tonight's lecture. I changed a
few of the functions to make them smaller.
Please look over the code and try to write the "update-dirs"
function for class on Monday. Fooling around with the code will teach
you more than you can learn by watching it in class.
Wednesday, January 23rd, 2008
Here's tonight's lecture. I added a little
extra, so take a look.
Tuesday, January 22nd, 2008
Assignment #3 is now posted; due Wednesday, 1/30

Here's touched up code from tonight's
lecture. DrScheme crashed before I could save it... but programs
are usually better the second time you write them.
Here's my best image... see what you can
do.
Wednesday, January 16th, 2008
Here's touched up code from tonight's
lecture. I'll try to post interesting code here as our collective
knowledge gets more complicated.

Because of the Snow and University closing, Bring your HW #1 to
hand in after class on Wednesday. Also, HW #2 is posted and due a
week from Wed.

The Class has moved to 110 Kariotis (#35 on map)
The room is much roomier... ironically.
Monday, January 7th, 2008
I was asked in class what characters can be used for
variable/function names? From the DrScheme documentation for R5RS
(a Scheme standard):
Extended alphabetic characters may be used within identifiers as
if they were letters. The following are extended alphabetic
characters:
! $ % & * + - . / : < = > ? @ ^ _ ~
In other words... a-z, A-Z, and the characters above can
begin a name. After the first character, you can use numbers
too.
