Concurrency, and Async: Three Ideas That Sound the Same But Aren’t
A guide to how modern software handles multiple tasks — with diagrams, code, and zero hand-waving.
Every developer has heard these three words. Most have used them in the same sentence. Many use them interchangeably. But concurrency, parallelism, and asynchronous programming are three distinct ideas, and confusing them leads to real bugs, bad architecture decisions, and interviews gone wrong.
This article takes each concept apart, builds it back up from scratch, and shows you exactly when and why you would reach for one over another.

Your Architecture Docs Are Lying to You (And AI Agents Are Making It Worse)
Ask any team for their architecture diagram. Then go read their Terraform state, their Helm charts, their CI/CD pipeline configs. Compare the two. They will not match. They never do. This gap has a name in research circles: architecture erosion, architectural drift, and it has existed since the first team drew a box-and-arrow diagram and then shipped code that didn't follow it.

The Growing Impact of Global Warming on Our Planet
Global warming is one of the most serious environmental challenges facing the world today. It refers to the gradual increase in Earth’s average temperature, mainly caused by the growing concentration of greenhouse gases in the atmosphere. Human activities such as burning fossil fuels, deforestation, industrial development, and excessive energy consumption have accelerated this process.
