Cache Write Policies

Write-Through

• Definition: Writes data to both the cache and main memory simultaneously.
• Synchronization: Cache and main memory are always synchronized.
• Write Speed: Slower, because every write goes to both cache and memory.
• Data Integrity: Ensures data in both cache and main memory is identical.
• CPU Performance Impact: Slower, due to the additional write to main memory.
• Use Cases: Ideal for systems where data consistency is critical (e.g., databases).
• Cache Miss Handling: Writes to both cache and memory on a miss.
• Complexity: Simple to implement; doesn't require tracking of data in the cache.

Write-Back

• Definition: Writes data to the cache first and only writes to memory when the cache line is evicted.
• Synchronization: Cache and main

Introduction: Echoes of 1984

George Orwell's 1984 depicts a society under Big Brother's control, where constant surveillance is the norm. Today, technology mirrors this reality, as we share personal information and activities, making us vulnerable to surveillance.

Erosion of Privacy

Social Media Overexposure

Firstly, young people and adults are often tethered to social media, sharing their daily lives and consequently sacrificing their privacy.

Digital Footprints and Surveillance

Secondly, the digitalization of our lives leaves data trails across various platforms, leading to mass surveillance.

1. Why is the Brain a "Miser"?

• The brain is often described as a "miser" because it strives to conserve cognitive resources and minimize mental energy expenditure. This principle, known as **cognitive miserliness**, refers to how the brain prefers using shortcuts and simplified processes to make decisions and respond to the world efficiently. It avoids complex, energy-consuming tasks whenever possible. This approach affects consumer behavior as shoppers tend to make decisions based on intuition and ease rather than through extensive deliberation.

Three Strategies of Cognitive Miserliness

• Efficiency

  Our brain uses heuristics, or mental shortcuts, to simplify decision-making processes. This includes reliance on quick judgments and familiar patterns

Preserving Our Community Library: An Urgent Appeal

I am writing to express my profound concerns regarding the proposed plan to replace our beloved community library with a supermarket. This critical information was gathered from the recent city council meeting where the proposal was discussed.

The Library's Indispensable Role

I firmly believe that replacing the library with a supermarket will have several significant disadvantages for our community. The library is far more than just a building; it serves as a dynamic hub for:

• Learning and Education: Providing access to diverse resources and educational

Improve Awareness

Social Media Content and Targeting Adjustments

• To improve CTR, develop more engaging visual content, like video snippets or interactive ads, highlighting time-sensitive offers. This can capture the attention of users who may not be actively searching but are interested in trending deals.
• Target refinement could be beneficial by narrowing audience demographics based on interest in categories popular during "Semana Fantástica," like electronics or fashion. This would maximize relevance and potentially improve engagement.

Collaborate with micro-influencers.

Sequential Messaging and Retargeting

• Sequential messaging (a series of ads that progressively introduce product benefits) could build familiarity for users who have already seen

Week 1: The Heart

Purpose of the Cardiovascular System

To provide adequate blood flow to all tissues/organs according to immediate needs.

Heart Contractions

• Systole: Periods of contraction
• Diastole: Periods of relaxation

Note: The atria contract simultaneously, followed by simultaneous ventricular contraction.

Blood Vessels

• Arteries: Carry blood away from the heart.
• Veins: Carry blood towards the heart.

Intrinsic Conduction System

1. Sinoatrial (SA) Node (Pacemaker): Generates impulses in the right atrial wall. Depolarizes 80-100 times per minute, modified by the autonomic nervous system to approximately 75 times per minute.
2. Atrioventricular (AV) Node: Impulses pause here for 0.1 seconds, allowing the atria to complete contraction. Generates impulses 40-60
