🚀 Ever wonder how Twitter or Instagram handles millions of hits on a celebrity post without crashing? That's the "Celebrity Problem", also known as the hot‑key problem. In a sharded database, a viral surge can flood one server while others sit idle. 💀 Here's how top architects solve it:
🛡️ Caching (Redis) – blocks read storms
⚙️ Dynamic key salting – spreads hot keys across servers
Watch this breakdown to see how databases survive viral moments.

Knowledge without action is just trivia. Intent without follow-through is just a wish. Do the work.

Frontend features every developer should know how to build, with proper implementation. Don't build basic versions. Build them like production apps. Here's what to implement for each:

1. Infinite Scroll: lazy loading, pagination, spinner, "no more data," error handling, debounce
2. Debounced Search: 300–500ms delay, API optimization, cancel previous requests, loading, no results, optional highlight
3. Loading Skeletons: skeleton UI with shimmer, matching layout, works for lists/cards
4. Toast Notifications: success/error/warning/info, auto and manual close, stacking, positioning
5. Modal Dialogs: outside click close, ESC, focus trap, scroll lock, smooth animation
6. Drag & Drop: indicators, animations, reordering, mobile support, save to backend
Build these with real UX, API handling, and performance, and you're already ahead of most frontend devs.

Don't spread yourself thin. Find what you're good at and build your whole game around it.
