Let's build a compressor from scratch

An educational blog post explaining the fundamentals of data compression, starting with simple boolean array serialization and expanding to generic compression algorithms like gzip. The author demonstrates how compression works through practical examples, showing significant size reductions for text and binaries but minimal effect on already-compressed formats like MP3.

Background

Data compression is a foundational concept in computer science, essential for storage optimization and network efficiency. This article serves as an introductory guide to understanding how compression algorithms work under the hood.
