Andrew Ng just dropped a 3-hour course on how to become an AI Engineer in 2026:
• 00:00 - How to build agentic AI systems
• 04:25 - Future of AI engineering
• 23:38 - AI Prompting full course
• 2:52:17 - Creating an app with AI in 30 minutes
This 3-hour watch could replace 10 AI engineering courses on the internet.
Watch it today, then read how to run a self-improving system in the article below.
LeetCode felt chaotic to me for the longest time.
I tried everything
random sheets
GFG
LeetCode discussions
long videos that explained solutions but never the why
Nothing really clicked.
Then I found this DSA patterns sheet and things finally snapped into place.
Instead of throwing 1000 problems at you, it breaks them into clean, intuitive patterns. Once you see the pattern, the problems stop feeling new.
They’ve put all the pattern videos into a single playlist now, and more are coming.

This is the kind of structure I wish I had when I started DSA.
