🔐 How does SSH work?

✔️ SSH (Secure Shell) is a network protocol used to securely connect to remote machines over an unsecured network. It encrypts the connection and provides various mechanisms for authentication and data transfer.

It has three main layers:


1️⃣ Transport Layer
The Transport Layer provides encryption, integrity, and data protection to ensure secure communication between the client and server.

2️⃣ Authentication Layer
The Authentication Layer verifies the identity of the client to ensure that only authorized users can access the server.

3️⃣ Connection Layer
The Connection Layer multiplexes the encrypted and authenticated communication into multiple logical channels.

🖼️ Rendering Strategies With Nuxt 3

✔️ With Nuxt 3, there are different rendering strategies for specific situations and purposes. Rendering refers to the interpretation of JavaScript code by both the browser and the server to convert Vue.js components into HTML elements.

1️⃣ Universal Rendering

Advantages: Enhances SEO, improves initial page load performance.
Disadvantages: More complex to implement due to dual rendering paths.
Usage: Best for applications that benefit from both SEO and rich client-side interactivity.

2️⃣ Hybrid Rendering

Advantages: Flexibility to use the best rendering method for each application part, optimizing performance.
Disadvantages: Increased complexity in configuration and potential overhead in maintaining different rendering paths.
Usage: Ideal for large applications with diverse content needs (dynamic, static, interactive).

3️⃣ Server-Side Rendering (SSR)

Advantages: Faster initial load time, better SEO, simplified debugging, and improved accessibility.
Disadvantages: Higher server resource requirements and potentially slower subsequent page loads.
Usage: Suitable for content-heavy sites where SEO and initial rendering speed are critical.

4️⃣ Client-Side Rendering (CSR)

Advantages: Lower server load, simpler deployment, and dynamic interfaces.
Disadvantages: Slower initial load, poorer SEO, and reduced accessibility for some users.
Usage: Best for interactive single-page applications where SEO is not a priority.

5️⃣ Static Site Generation (SSG)

Advantages: High performance, enhanced security, and reduced server load.
Disadvantages: Not suitable for sites requiring frequent updates.
Usage: Ideal for websites with static content, such as blogs and documentation.

6️⃣ Incremental Static Regeneration (ISR)

Advantages: Combines the benefits of static generation with flexibility for content updates, maintaining high performance.
Disadvantages: More complex to set up and manage compared to traditional SSG.
Usage: Perfect for sites that need regular content updates but also want the performance benefits of static rendering.

🔠🔠🔠 What is the Model Context Protocol (MCP)?


➖ MCP is an open standard developed by Anthropic that standardizes how AI applications, particularly large language models (LLMs), connect to external data sources and tools. It simplifies integrations by providing a universal protocol, like a USB-C for AI, enabling secure, scalable, and context-aware interactions without custom APIs for each tool or data source.


🟡AI assistants have entered their intern era. They'll ace any single task you throw at them—analyzing PDFs, generating SQL, cracking dad jokes about Kubernetes—but ask them to coordinate across Slack, Gmail, and Jira? Now you're debugging a Rube Goldberg machine of API keys.


🟡 Anthropic's Model Context Protocol (MCP) aims to standardize this mess. For users, it means connecting AI models to your Figma file and Linear tickets without needing a CS degree. For developers, it means fewer "why is the model just returning goat emojis" moments.

🖼️ The Hidden Cost of JavaScript Arrays (Part 1 - Memory Allocation)


✔️ JS arrays can tank performance and there are ways to optimize them.

❌ Operations like push(), pop(), and splice() can trigger memory reallocation, copying, and fragmentation.

✅ Using fixed-size or oversized arrays can be more efficient.

// Inefficient: Repeatedly resizing the array

let arr = [];

for (let i = 0; i < 10000; i++) {
  arr.push(i);
}

// Efficient: Using a pre-sized array

let arr2 = new Array(10000);


for (let i = 0; i < 10000; i++) {
  arr2[i] = i;
}
