Caching is a technique used to store frequently queried data that changes infrequently, thereby reducing request latency. This article discusses implementing caching for storing database query results, specifically for the `book_reviews` API, which is frequently accessed yet returns data that doesn't change often. By caching the book reviews locally at the application level, we can mitigate the inefficiency of repeatedly querying the database, which improves overall latency for other critical queries. The key components outlined include: 1. **Entity**: Use of the `

The blog series aims to implement a minimal userspace TCP/IP stack for Linux as an educational tool to deepen understanding of network and system programming. Although creating a TCP/IP stack might appear daunting due to TCP's extensive specifications, the core components include TCP header parsing, state machine, congestion control, and retransmission timeout computation. In comparison, commonly used layer 2 (Ethernet) and layer 3 (IP) protocols are simpler. To manage low-level network traffic from the Linux kernel, the series

The internet is inherently insecure, allowing attackers to intercept and modify traffic, which necessitates secure communication methods and server identity verification. While encryption protects data privacy, it does not prevent hackers from impersonating legitimate websites if they can’t be verified. This is where TLS (Transport Layer Security) comes into play, combining encryption with authentication. The browser's lock icon indicates encrypted communication and confirms the website's identity. In the context of TLS communication, the terms client/browser and server/website are interchangeable. Before
