Building a mobile game for 10M players. You need a real-time leaderboard for the top 10k. Your SELECT * FROM scores ORDER BY score DESC LIMIT 10000 query runs thousands of times/sec with 1M concurrents. Your DB CPU hits 100%, and the game lags for everyone. How do you design a…

Quick question : You build a data pipeline. A fast "producer" service generates 10,000 events per second and puts them on a queue. A slower "consumer" service pulls them off to write to a database, but it can only handle 1,000 per second. At first, it's fine. But the queue…

Quick question : You need to add a new, required phone_number column to your users table, which has 500 million rows. You write a simple ALTER TABLE script. You run it during a "maintenance window." It locks the entire users table for 8 hours while it adds the new column to…

"Just fine-tune your embeddings" they said. "It'll fix your RAG system" they said. They were wrong. Here's what actually works: After working with countless retrieval systems, I've noticed a pattern: teams often jump straight to fine-tuning when their vector search…

"Teach Yourself Computer Science" is the best resource to learn CS. 2 weeks into vibe coding and non-technical people feel the pain. "I really wish I was technical. I just don't know how to proceed." It takes ~1000hrs across 9 topics to understand CS with any depth.

Think about it. You alone can build anything - like a video streaming website, using ffmpeg, running on Linux, in AWS EC2. That’s centuries of human work and research, accessible with a few clicks and keystrokes. If you say internet + coding isn't magic, you're insane.
