1. Take the office number (ignoring the 70-) of each faculty member,
then perform the relevant math (the thing on top is the determinant).
You should get 3551, which is SAMPATH's office.

2. Fix the code and run it, assuming you enter 3, it should print
out the answer MUDROOM.

3. This program runs a chat client (over the CS2 Chat project protocol).
Hunters found a bot called HuntBot (and one called Hunters-talk-to-HuntBot).
Ask the bot for a word by sending any message that contains "word".
If you continue to do this repeatedly, it will respond with randomly chosen
words - the first one a word beginning with G, the second a word
beginning with A, the third with T, until the eighth word again begins
with G and the cycle repeats.  The first letters of these words always
spells GATHERS.

4. The numbers all refer to NY state road numbers (yes, even the 90
at the bottom, that's not the Thruway!).  Starting with RIT
as the root, draw the pattern these roads make.  It should draw out
the word MUFFLER (more or less).

5. Each clue can be answered by a two-letter answer.  The second letters
of these 26 answers consists of each letter exactly once - so arrange the
answers by their second letters and read the first letter of each; it spells
"Subject of 'The Catcher was a Spy'", which refers to MOEBERG.

6. Open the PDF file in a text reader, and you will see the comment:
%% Puzzle hunters, this is your secret info: Read every 13th letter
%% of the overt text of this document, starting from the 5th.
Doing so gives answerathlete, so the answer is ATHLETE.

7. The long entries in the crossword read "Read the letter / below each I /
in this grid / for a final clue".  Doing so gives "golden big ten athletes",
referring to the Minnesota Golden GOPHERS.

8. Each image refers to a short word.  For each test image, find a library
image that is the same word but with a letter removed.  Reading the extra
letters in the test images column by column spells "comes due, as a bond", 
a clue for MATURES.

9. The answers to the trivia correspond to the letters of "numbers in a sum",
a clue for ADDENDS.

10. The computers listed can be found on a single bench in each ICL 
(plus the CSL). In each case, one machine on that bench is not listed.
Take those machine names, alphabetize them (as suggested by the
given machine names) and take the fourth letter of each (as vaguely
suggested by the last ten machine names starting with the letters of
"take fourth") to spell ROUTERS.

11. This is a simple letter substitution cypher - in fact, it's just ROT-13.
It spells: CONVERT THE NUMBER SIX NINE TWO THREE FIVE SIX
EIGHT TWO SEVEN EIGHT (BASE TEN) TO BASE TWENTY-SIX.  Doing so
gives MAILING, the answer.

12. These are all items that can be purchased at Sandella's in
building 70.  Compute the total bill for each group including 8% sales
tax.  You should get the amounts (left side) $31.05, $34.12, $37.08,
$33.05, (right) $35.01, $32.25, $36.19.  Note that the dollars are
consecutive numbers, 31 through 37.  Order the totals in increasing
order and convert the cents to letters (A=1, Z=26) to spell EYELASH.

These twelve answers can only be placed in the crisscross of the
capstone in one way.  Reading off the numbered squares in order
spells: "SEFOLDEROFARANDOMHUNTER", and indeed, if you went down to the
SE department during the hunt, you would have found a folder for a
student named "Hunter, A. R."  containing an interoffice envelope
addressed to A. Random Hunter, inside which the diplomas were located.
