Artificial Intelligence, a Pragmatic Introduction
A first, simple look at AI, why it boils down to geometry, math and code, with a tiny iris-classifier example along the way.
Data Structures and Algorithms
Doubly Linked List
A doubly linked list in Python, its Node class, and the append, pop, and prepend methods.
Linked List, common problems #2
Three more linked-list interview problems in Python, finding the kth node from the end, removing duplicates, and reversing a sublist.
Linked List, common problems #1
Three classic linked-list interview problems solved in Python, reversing a list, finding the middle node, and detecting a loop.
Basic Operation of a Linked List, #2
Adding prepend, pop_first, get, set_value, and insert to the Python LinkedList class.
Basic Operation of a Linked List, #1
Implementing append, pop, and print for the Python LinkedList class, one method at a time.
Linked List
What a linked list is, why it is useful, and a first pass at the Node and LinkedList Python classes.
Design Patterns
Singleton Pattern
Implementing the Singleton design pattern for a Redis client, first in Go with sync.Once, then in Python with __new__.
