No. You may work with only one partner on labs and MPs unless otherwise noted.

How does the PNG coordinate system work?

The upper left corner is (0, 0). A PNG with width == 3, height == 4 has coordinates:

+--------+--------+--------+
|        |        |        |
| (0, 0) | (1, 0) | (2, 0) |
|        |        |        |
+--------+--------+--------+
|        |        |        |
| (0, 1) | (1, 1) | (2, 1) |
|        |        |        |
+--------+--------+--------+
|        |        |        |
| (0, 2) | (1, 2) | (2, 2) |
|        |        |        |
+--------+--------+--------+
|        |        |        |
| (0, 3) | (1, 3) | (2, 3) |
|        |        |        |
+--------+--------+--------+

How do you run ASAN/Valgrind on a Mac?

Unfortunately, Valgrind doesn’t support newer Macs. For ASAN, Apple doesn’t provide a version of Clang that is ASAN-enabled. You can try compiling it yourself, but how to do that is out of the scope of this page.

Can I work on HW 0 with a partner?
