+### Day 9:
+Going to be writing some more add-ons to nmap module. Also, added an example of
+a bubble sort algorithm in python, and accompanied it with a wikipedia
+description of the algorithm. I am going to be looking into implementing
+another type of sorting algorithm today.

+### Day 10:
+Made fibonacci programs from tutorials I found on youtube. One that introduces
+the concept of memoization or storing results of recent function calls to
+improve the speed of the recursive function. Also a basic bubblesort program in python
+that I found from another tutorial. This is very basic stuff but I want to make sure I
+know as much foundational knowledge as I can. Socrataca on youtube is a great
+channel with lots of math and science themed videos. That is where I found
+these tutorials. Here is a
+[link](https://www.youtube.com/watch?v=Qk0zUZW-U_M&list=PLi01XoE8jYohWFPpC17Z-wWhPOSuh8Er-&index=18)
+to the python video on the fibonacci sequence.
