Sustainable Diets, Millennial Pet Choices & Gen Z Work Trends
Sustainable Diets and Meat Consumption
1 The connection between the food we eat and the health of our planet has become a major topic of discussion in recent years. As climate change accelerates and natural resources become scarcer, many people are looking at how our diets, especially how much meat we consume, affect the environment. Opinions on this issue vary widely. Some argue that adopting a fully plant-based diet is the only real solution. Others believe that simply eating less meat is a more

NATO: History, Structure and Missions
Created in 1949, at the beginning of the Cold War. The Washington Treaty established the alliance. 29 members (Europe and North America). Type: Military Alliance. NATO organizes regular summits for leaders of its member states and partnerships.
Founding and Cold War Era
1st period (1949–1989): Enemy: Warsaw Pact (1955). This military alliance was led by the Soviet Union. In 1966, Charles de Gaulle decided to withdraw from NATO’s integrated military command. During

vi Editor: Modes and Commands
The vi editor is a powerful and commonly used text editor in Linux and Unix systems. It is mainly used to create, edit, and manage text files such as configuration files, shell scripts, and program source code. vi works in different modes, which makes it efficient but slightly difficult for beginners.
Modes of the vi Editor
vi editor works in three main modes:
Command Mode
- Default mode when vi starts.
- Used for navigation, deleting text, copying, and saving files.
- Example commands:

Microcontroller Addressing Modes and Assembly Programming Concepts
1. Define Addressing Mode
Addressing Mode Definition
An addressing mode is the method a microcontroller uses to specify the location of the data (operand) required by an instruction. It determines how and from where the CPU fetches data—whether from a register, a memory address, an immediate constant, or through pointer-based access.
Why Different Addressing Modes Are Used
Different addressing modes are provided to achieve:
Programming Flexibility
Allows data to be accessed in multiple ways—direct,

W1.1 Operating Systems Fundamentals
W1.1.1 OS Introduction
W1.1.2 Types of Operating Systems
Examples of Operating Systems include: Android, Linux, FreeBSD, MacOS, MS-DOS, Windows, uCOS, VxWorks. These systems are suited to small, medium, or large systems, exhibiting different characteristics regarding:
- Responsiveness
- Efficiency
- Flexibility
- Security
- Reliability
W1.1.2 Different Kinds of OS
Operating systems are categorized based on their usage:
- Single-user systems: Execute one program at a time for one user.
Regression, Regularization and Time Series Concepts for ML
1. Univariate linear regression assumptions
- Linearity: The relationship between X and Y is linear.
- Independence: The residuals (errors) are independent of each other.
- Homoscedasticity: The variance of residuals is constant across all levels of X.
- Normality of errors: The residuals follow a normal distribution.
These assumptions are important because they ensure the reliability and accuracy of the linear regression model. If the relationship between X and Y is not truly linear, the model won’t capture

Bell’s Palsy Etiology
Idiopathic; commonly associated with HSV-1, VZV. Autoimmune inflammation or ischemia is suspected. Sporadic outbreaks are reported.
Clinical Features
- Mastoid/ear pain precedes weakness by 1–2 days.
- Rapid onset facial weakness within 48 hours.
