 Some subjects take one day, and some will take multiple days. Some are just learning with nothing to implement.
 
 Each day I take one subject from the list below, watch videos about that subject, and write an implementation in:
-    C - using structs and functions that take a struct * and something else as args.
-    C++ - without using built-in types
-    C++ - using built-in types, like STL's std::list for a linked list
-    Python - using built-in types (to keep practicing Python)
-    and write tests to ensure I'm doing it right, sometimes just using simple assert() statements
-    You may do Java or something else, this is just my thing.

 Why code in all of these?
-    Practice, practice, practice, until I'm sick of it, and can do it with no problem (some have many edge cases and bookkeeping details to remember)
-    Work within the raw constraints (allocating/freeing memory without help of garbage collection (except Python))
-    Make use of built-in types so I have experience using the built-in tools for real-world use (not going to write my own linked list implementation in production)

 I may not have time to do all of these for every subject, but I'll try.
