The History of AI
- AI originated from ancient myths and stories, but took shape in the 20th century.
- Alan Turing posed the question of whether machines can think, leading to the creation of the Turing Test.
- AI saw progress in the 1960s and 1970s, but faced setbacks in the AI Winter of the 1970s and 1980s.
- Expert systems and the rise of machine learning revived AI in the 1980s and 2000s respectively.
- AI gained prominence in the 2010s with advancements in big data and cloud computing.
- The future of AI involves its pervasive presence and challenges in ethics and regulation.

LeetCode Challenge: 380. Insert Delete GetRandom O(1) - JavaScript Solution 🚀
- Design a class RandomizedSet that supports insertion, deletion, and random access in O(1) time complexity.
- The implementation uses a hash map for quick lookups and updates and an array for constant-time random access.
- The insert operation adds the value to the end of the array and stores the value's index in the map.
- The remove operation replaces the element to be removed with the last element in the array, updates the last element's index in the map, and removes the last element from the array.

Build Enumerations of Constants With Python's Enum
- Python's enum module allows creating enumerations which is a data type to group related constants.
- Enum class is used either by subclassing or functional API to create enum types.
- Enumerations provide structure, offers prevention of reassignment and code readability.
- Enums can work with data types like integers or strings, enhancing their flexibility.
- Access to enum members can be with dot notation, call notation, or subscript notation.
- Iteration over enum members is possible using loops and the members attribute.
- Enumerations are immutable and discrete sets of constant values, representing limited possible variable values.
- Python 3.4 added the Enum class to the standard library to support general-purpose enumerations.
- The Enum class allows defining related constants as enum members.
- Creating enumerations is easy by either subclassing Enum or using its functional API.

Object-Oriented Programming (OOP) in Python
- Object-oriented programming (OOP) in Python involves structuring code into classes to model real-world entities.
- The four key concepts of OOP in Python are encapsulation, inheritance, abstraction, and polymorphism.
- OOP in Python is considered straightforward to learn due to its clear syntax and readability.
- The main focus of OOP in Python involves creating classes as blueprints for objects. These objects contain data and the methods needed to manipulate that data.
- OOP models real-world entities as software objects that have some data associated with them and can perform certain operations.
- Encapsulation allows you to bundle data (attributes) and behaviors (methods) within a class to create a cohesive unit.
- Inheritance enables the creation of hierarchical relationships between classes, allowing a subclass to inherit attributes and methods from a parent class.
- Abstraction focuses on hiding implementation details and exposing only the essential functionality of an object.
- Polymorphism allows you to treat objects of different types as instances of the same base type.
- You define a class in Python by using the class keyword followed by a name and a colon. Then you use .__init__() to declare which attributes each instance of the class should have.

Python Classes: The Power of Object-Oriented Programming
- Python classes form the backbone of object-oriented programming, enabling you to encapsulate data and behavior into a single entity.
- A class in Python serves as a blueprint for creating objects, which are instances of the class.
- By defining classes, you can create multiple objects that share the same attributes and methods, while maintaining their own unique state.
- Methods define behaviors, while attributes store data within class instances.
- Instance attributes are unique to each object, while class attributes are shared across all instances of the class.
- To define a class, you need to use the class keyword followed by the class name and a colon.
- Attributes are variables defined inside a class with the purpose of storing all the required data for the class to work.
- Methods are functions that you define within a class.
- In Python, the body of a given class works as a namespace where attributes and methods live. You can only access those attributes and methods through the class or its objects.
- As an example of how to define attributes and methods, say that you need a Circle class to model different circles in a drawing application.

Dependency Management With Python Poetry
- Poetry is a tool for managing Python projects that simplifies dependency management.
- You should generally install Poetry system-wide using tools like pipx.
- Basic Poetry CLI commands include poetry new, poetry add, poetry install, and poetry update.
- The poetry.lock file locks dependency versions, ensuring reproducible environments.
- You can install Poetry system-wide using pipx or the official installer for better environment management.
- Installing Poetry with pip in a project’s environment is not recommended due to potential dependency conflicts.
- You resolve dependency conflicts by updating the poetry.lock file with poetry update or poetry lock.
- Best practices include committing the poetry.lock file to version control and avoiding system-wide package installations.
- Poetry can also help you build a distribution package for your project.
- You can use Poetry to publish your project on the Python Packaging Index (PyPI).

Technical Bias: The Invisible Force Shaping Our Architecture Decisions
- Our cognitive biases often shape our architectural decisions, often at the expense of practical solutions.
- Biases lead to the dismissal of potential solutions that don't align with technology preferences, resulting in technical debt.
- The three pillars of technical prejudice are the stack comfort trap, the innovation fallacy, and the echo chamber effect.
- To break the cycle, technical directors should measure impact, challenge default choices, and implement requirements for architectural decisions.
