Docker Guidelines Dockerfile Best Practices Use Official Base Images Why: Official images are maintained and frequently updated, ensuring reliability and security. How: FROM node:14-alpine Minimize Image Size Why: Smaller images lead to faster deployments and reduced storage costs. How: Use minimal base images (e.g., Alpine Linux). Remove unnecessary packages and files. Combine commands to reduce layers. RUN apt-get update && \ apt-get install -y package1 package2 && \ rm -rf /var/lib/apt/lists/* Leverage Caching Why: Utilizing Docker’s layer caching speeds up builds. [Read More]

Introduction Kubernetes (k8s) is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. Kubernetes Architecture Masters The master node manages the Kubernetes cluster. It coordinates all activities, such as scheduling, scaling, and updating applications. Components: API Server: The front-end of the Kubernetes control plane. etcd: A distributed key-value store for configuration data. Controller Manager: Manages controllers that handle routine tasks. Scheduler: Assigns workloads to nodes based on resource availability and policies. [Read More]

Introduction to Lua Lua is a powerful, efficient, lightweight, embeddable scripting language. It is designed to be embedded in other applications, providing flexibility and extensibility. Lua is widely used in game development, embedded systems, web applications, and more due to its simple syntax, fast execution, and ease of integration. What is Lua? Key Features Lightweight and Fast: Lua is designed to have a small footprint and execute rapidly, making it ideal for performance-critical applications. [Read More]

Introduction to Nginx Nginx (pronounced as “Engine-X”) is a high-performance, open-source web server, reverse proxy server, and email (IMAP/POP3) proxy server. It is renowned for its ability to handle high concurrency, low memory usage, and exceptional speed, making it a popular choice for serving both static and dynamic content on the web. What is Nginx? Key Features High Performance: Ability to handle thousands of concurrent connections with minimal memory footprint. Reverse Proxying: Acts as an intermediary for requests from clients seeking resources from servers. [Read More]

Introduction to OpenResty OpenResty is a dynamic web platform that integrates Nginx with the powerful Lua scripting language. It is designed to build scalable web applications, web services, and dynamic web gateways. By combining the high performance of Nginx with the flexibility of Lua, OpenResty enables developers to handle complex processing at the edge of the network. What is OpenResty? OpenResty extends Nginx by bundling it with a set of powerful Lua libraries and modules (known as LuaJIT). [Read More]

1. Strings Strings in Go are immutable sequences of bytes, typically used to represent UTF-8 encoded text. Structure type stringStruct struct { str unsafe.Pointer len int } Memory Layout stringStruct +----------------+ | str (uintptr) | ---> [byte array] | len (int) | +----------------+ Detailed Implementation Creation When a string literal is used, the compiler allocates the bytes in read-only memory. Runtime string creation (e.g., string concatenation) allocates new memory and copies bytes. [Read More]

Binary Tree A binary tree is a tree data structure in which each node has at most two children, referred to as the left child and the right child. B-Tree A B-tree is a self-balancing tree data structure that maintains sorted data and allows searches, sequential access, insertions, and deletions in logarithmic time. It is optimized for systems that read and write large blocks of data. B+ Tree A B+ tree is an extension of a B-tree, optimized for systems that read and write large blocks of data. [Read More]

What is the difference between an array and a linked list? Array: Fixed size (in most languages) Contiguous memory allocation Fast random access Insertion/deletion is expensive (except at the end) Linked List: Dynamic size Non-contiguous memory allocation Slow random access Fast insertion/deletion Explain the difference between a stack and a queue. Stack: Last-In-First-Out (LIFO) structure Push (insert) and pop (remove) operations occur at the same end Used for function calls, undo mechanisms, expression evaluation Queue: [Read More]
