+### Takeaway
+- Programming paradigms: 
+  - Imperative programming
+    - A programming paradigm that describes how to change a state.
+  - Declarative programming
+    - A programming paradigm that describes what to do, not how to do it.
+  - Procedural programming
+    - A programming paradigm that breaks down a task into a sequence of steps.
+  - Object-oriented programming
+    - A programming paradigm that models the real world as objects that interact with each other.
+  - Functional programming
+    - A programming paradigm that relies on the evaluation of mathematical functions.
+  - Typed programming languages
+    -  Programming languages that assign types to variables and expressions.
+  - Untyped programming language
+    - Programming languages that do not assign types to variables and expressions.
+  - Programming principles: 
+    - Programming principles are general guidelines for writing good code. They can help make code more efficient, easier to maintain, and more reliable.
+    - SOLID principles: The SOLID principles are a set of five principles that are widely accepted as being good practice in object-oriented programming. They can help make code more modular, reusable, and maintainable.
+    - STUPID principles: The STUPID principles are a set of six bad practices that can make code more difficult to write, test, and maintain. They should be avoided whenever possible.
+    - In addition to the SOLID and STUPID principles, there are many other programming principles that can be helpful. Some of these principles include:
+      - KISS: Keep It Simple, Stupid
+      - FCoH: Favor Composition over Inheritance
+      - SLA: Single Layer of Abstraction
+      - YAGNI: You Ain't Gonna Need It
+      - IOC: Inversion of Control
+      - DI: Dependency Injection
+      
+### Perception
+
+**Programming principles**
+
+ I will apply SOLID principles and avoid STUPID principles to my group project to ensure that my code is modular, reusable, maintainable, and easy to write, test, and maintain. I will also use design patterns and best practices to implement the principles effectively.
+
+### Repetition
+
+ Programming pragmatism is the practice of prioritizing practical solutions over theoretical perfection. It is the belief that the best solution to a problem is the one that works, even if it is not the most elegant or efficient.
