Introduction to Code Pages: Legacy Character Encoding Systems

Code pages were once the backbone of character encoding in computers, providing a way to map binary values to text in different languages. However, they had significant limitations, particularly when dealing with multiple languages at once. This article explores the history of code pages, how they were used, and why they have been largely replaced by the modern Unicode standard, which offers a universal character set for all languages.

Implementing Regular Expressions (RegEx) from Scratch in Python

Implementing Regular Expressions (RegEx) from scratch in Python provides a deeper understanding of how RegEx works. This tutorial guides you step-by-step through creating a RegEx engine using finite automata, covering essential RegEx operations, converting RegEx to NFA using Thompson’s Algorithm, and building a full-featured RegEx engine.
