Burrows Wheeler Transform BWT Preparing Data for Efficient Compression
Introduction Data compression is not only about reducing file size it is about transforming data into a form that can be encoded more efficiently. One of the most elegant examples of this idea is the Burrows–Wheeler Transform (BWT). Unlike traditional compression algorithms that directly reduce data size, BWT is a reversible data transformation that…

Quantum Data Compression Trading with Reality in an Irreversible Future
Introduction: Compression Beyond Classical Intuition In classical computing, data compression is a reversible engineering problem. Information is encoded redundantly, statistical patterns are exploited, and within theoretical limits such as Shannon entropy data can be compressed and later reconstructed with perfect or near-perfect fidelity. Quantum computing breaks this intuition entirely. Quantum data compression is not…

P4 Programming Protocol-Independent Packet Processors
Building Programmable Networks Directly in Hardware Introduction Modern networks are no longer just passive packet-forwarding fabrics. They are expected to enforce security policies, perform real-time telemetry, mitigate attacks, and adapt dynamically to application needs. Traditional network devices, however, rely on fixed-function data planes, where packet parsing and processing logic is hard-coded into ASICs. This…

Event Sourcing Storing History Instead of Final State
A Deep Dive into a Paradigm Built for Transparency, Auditability, and Time-Travel Modern software systems are increasingly expected to be auditable, resilient, and explainable. In domains like finance, banking, healthcare, and large-scale platforms, knowing what the current state is is no longer enough we must also know how we got there.This is where Event…

Post-Quantum Cryptography (PQC) Securing the Digital World Against Quantum Computers
Introduction Why Cryptography Must Evolve Modern digital security is built on cryptographic foundations such as RSA, ECC, and Diffie–Hellman. These algorithms protect everything from online banking and cloud storage to messaging apps and national infrastructure. However, the emergence of quantum computing threatens to undermine this foundation entirely. Quantum computers, once sufficiently powerful, will be…
