 Also, new things that I've learned so far include the `objdump` command that can disassemble an executable, extract symbols, and getting more familiar with using GDB. At the time of writing this, I'm doing homework 2 - bomblab - reverse-engineering an executable to find six secret phrases that will defuse the bomb. It was super overwhelming when I began last week, but today I have found 3 codes so far. And it has become super fun! Analyzing the machine/assembly instructions, following the flow of logic, trying to reason about things while keeping an eye on the processor state and flags. This properly taught me how the processor handles argument passing beyond the registers (spoilers: it uses the stack) between procedures, and calling conventions properly, which I, unfortunately, skipped in my college classes.
 
+**Update**: I solved bomblab! Phew, it was hard. The moment you have to decode usage of a data structure, it gets complicated real fast, in my opinion.

 I will keep this blog post updated as I make progress. So keep an eye out for that!
