How to use this list? 
- These numbers are Leetcode problem numbers
- Do 3 patterns at a time, not all 30 together.
- For each pattern, solve the first 2 to understand the idea, the next 2 to get repetition, and the last 2 to stretch yourself.
- After every pattern, write one reusable template from memory.
- Do not just “solve and move on.” Ask: what signal in the question pointed to this pattern?
- If you get stuck, revisit the same pattern after 3 to 4 days. Pattern recognition is built by spacing, not cramming.

@Tech_geek001 @freeCodeCamp yo how many hours is this course

[Utkarsh Sharma @techxutkarsh]

A senior Google engineer just dropped a 421-page doc called Agentic Design Patterns.

Every chapter is code-backed and covers the frontier of AI systems:

→ Prompt chaining, routing, memory
→ MCP & multi-agent coordination
→ Guardrails, reasoning, planning

This isn’t a blog post. It’s a curriculum. And it’s free.

[Oliver Prompts @oliviscusAI]

someone built a web-based System Design Simulator.

you drag and drop components (api gateways, dbs, caches) and it actually simulates real-time traffic.

you can watch latency, bottlenecks, and failures happen live...

[cvxv666 @antpalkin]

> be a chinese student
> work on small projects for your graduation on GitHub
> vibecoding data simulation systems using Cursor
> hits 60k stars on GitHub with 2 repo (BettaFish, MiroFish)
> get noticed by Chen Tianqiao, the former richest man in the Chinese internet industry
> secure $4M in funding from Chen
> go from student to CEO of a promising AI startup with backing from internet giants in <6months
> still believe that AI will one day learn to predict the future
