🤖 Day 16 - #AIEngineerSeries Reinforcement Learning Reinforcement Learning (RL) is a type of Machine Learning where an AI agent learns by interacting with its environment. Instead of learning from labeled data, the agent learns through trial and error. Good actions receive rewards, while bad actions receive penalties. Over time, the agent learns the best strategy to achieve its goal. How it Works 🤖 Agent → 🎯 Action → 🌍 Environment → 🏆 Reward / Penalty → 🔁 Learn & Improve Example Think about a baby learning to walk. 👶 The baby tries to stand and walk. 🏆 If the action is successful, the baby gets a reward (encouragement or reaching a toy). ❌ If the baby falls, it learns from the mistake and tries again. After many attempts, the baby learns to walk confidently. Real-World Examples 🚗 Self-Driving Cars – Learn safe driving decisions. 🎮 Game AI – Learn to play games like Chess, Go, and Dota 2. 🤖 Robotics – Learn how to move and perform tasks. 📦 Warehouse Automation – Optimize picking and delivery routes. Reinforcement Learning teaches AI through experience, making it ideal for problems where the best solution is discovered over time. #AI #AIEngineer #MachineLearning #ReinforcementLearning #ArtificialIntelligence #LearnAI

how to get $5 to $483 usdc for using chatgpt and claude moonpay is paying us to install their mcp > go to: paybox.sh - select claude or chatgpt - follow the instructions on the site - turn on developer mode & add the mcp - then go to the paybox site and signup with email - connect x and claim usdc > currently the usdc is not showing in paybox wallet, let's wait for sometime before celebrating - in terms of giving data? brother it's 2026, they will take data from you no matter what safety precaution - go to settings on x - security and account access - apps and sessions - connected apps - revoke paybox by moonpay once you are done

Will it get indexed by Google,, Gotta be careful.... site:claude.ai/public/ Can search for 〇〇😱

This Chinese guy exploited an authorization vulnerability on Anthropic’s side and got the $214.2 Claude Max subscription for $0 😳 IMPORTANT: don’t attempt anything like this on your devices. Anthropic will patch it soon, and trying it can get your device banned. He built a five-step local workflow on a single machine. This involved no servers shared accounts or a team. Instead he used a VPN, Tampermonkey, a new Claude account and a dummy SEPA payment. Traditional users pay full price every month. His cost: $0. Here’s the exact flow he ran: → VPN layer: Installed a VPN and set the exit node to Germany. → Account layer: Created a fresh Claude account and selected the Max plan. → Injection layer: Loaded a widely shared Tampermonkey script (common in certain Chinese communities) that altered the client-side authorization checks. → Payment layer: Chose SEPA debit as the payment method and entered a dummy IBAN. → Activation: Submitted. The subscription activated at $0. That’s it. On paper it looks clean. In reality it’s an authorization bug on Anthropic’s side that let the request bypass the real charge. He has No team. No office. No credit card. Just a browser, a VPN, one userscript, and a dummy IBAN. Usage after activation was normal Max-tier access. The only ongoing “expense” was the risk of a future device or account ban once Anthropic closes the hole. One vulnerability. One temporary window. Cleanest (and riskiest) FREE Max sub I’ve seen this year. Don’t try it. Disclaimer: Based on public reports and discussions. Shared for educational and security awareness purposes only.
