Title text: Every computer, at the unreachable memory address 0x-1, stores a secret. I found it, and it is that all humans ar—SEGMENTATION FAULT.
This comic is about a play on the dual meaning of the word "pointer". Cueball is playing a video game in the comic, but he seems to be stuck. So he asks Black Hat for a few tips ("pointers") to get unstuck again. Black Hat wants to be annoying, so he spits out a couple of (seemingly random) 32-bit hexadecimal addresses, which are "pointers" in a programming language. These pointers are used to access a certain location in the computer's memory in order to fulfill a task. Cueball is then annoyed at Black Hat for not answering his question.
A segmentation fault, as referred to in the title text, is a result by accessing invalid memory addresses. If you define a pointer to an invalid address, then try to access the memory location associated with it, you could end up with this exception. The hexadecimal address 0x-1 is definitely invalid, because it's out of range. If you treat pointers as signed numbers, it points below the lowest address, 0; if you treat them as unsigned (meaning the numbers wrap around, so -1 is the same as the highest address - 0xFFFFFFFF on a 32-bit system), if it's pointing at any object larger than a byte, most of that object is past the highest address. So, this is a "hidden location", but as soon as you try to read more than one byte at that location, you will get a segfault.
The ending letters of the pointers are spelling, reading top to bottom, the word ACE. As Cueball is playing a game Black Hat could be additionally saying he's an ace of that game.

- Cueball: Man, I suck at this game. Can you give me a few pointers?
- Black Hat: 0x3A28213A 0x6339392C, 0x7363682E.
- Cueball: I hate you.
