The article walks through creating a compact 250‑line Rust gzip decompressor from scratch, explaining gzip’s header, DEFLATE block types, bit‑reading logic, Huffman coding, and LZ77 back‑references, and shows how to test it with real compressed data, highlighting key implementation challenges and trade‑offs.
This article chronicles Jacob Ziv’s pioneering contributions to lossless data compression, tracing the evolution from early Morse code through Shannon‑Fano and Huffman to the groundbreaking LZ77 and LZ78 algorithms, and highlights his biography, major awards, and lasting influence on modern digital media and storage technologies.
This article explains the PNG image format, covering its full name, lossless compression, size advantages, transparency support, the three main PNG types, the file’s chunk‑based data structure, hexadecimal header details, factors that affect compression efficiency, and the two‑stage prediction‑and‑deflate compression process.
