Why physical distance kills speed. Consistent Hashing, Edge Computing, Cache Purge strategies, and how CDNs defend against DDoS attacks.
Why does my server crash? OS's desperate struggle to manage limited memory. War against Fragmentation.
Two ways to escape a maze. Spread out wide (BFS) or dig deep (DFS)? Who finds the shortest path?
A comprehensive deep dive into client-side storage. From Cookies to IndexedDB and the Cache API. We explore security best practices for JWT storage (XSS vs CSRF), performance implications of synchronous APIs, and how to build offline-first applications using Service Workers.
Fast by name. Partitioning around a Pivot. Why is it the standard library choice despite O(N²) worst case?
Three years ago when I built my first global service, I believed "good code makes fast services."
I was wrong.
Fast services are about beating physics.CDN isn't just a caching layer - it's infrastructure that defeats geography.
What I learned:
The truth: Modern web is impossible without CDN.
Netflix, YouTube, Facebook - every service we use has CDN behind it. We just don't see it.
Now you know the secret behind buffer-free streaming, instant websites, and unbreakable services.
Welcome to the world where geography doesn't matter anymore.
