Payton, you were the closest thing I had to a sister. It was such a privilege to grow up by your side, experience life together, and be able to love you. You were always putting a smile on others faces, filling rooms with laughter, and bringing people together. I truly don’t know what life will be like without, but I do know you will be missed beyond measure. I pray for our family, I pray for the many friends mourning you, and I hope you have found peace. I hope you know how much I loved you and I wish I had said it more. ❤️
Crip’s world, we’re just living in it 🥹🎣🦀💙
See you Sunday 😎

🚨 Interview question: 10,000 bots are hammering your login API. How do you stop them without locking out real users? Most people say "just block them." Here's why that fails 👇 ❌ Blocking IPs doesn't work. The bots come from thousands of different IPs, each sending only a few requests, so no single source looks suspicious. ❌ Login is expensive on purpose. bcrypt is deliberately slow so attackers can't guess passwords quickly. But that means every fake attempt burns real CPU, and enough of them turns an attack into an outage. ❌ Rate limits don't catch it. Attackers use email and password pairs leaked from other sites, with only 1-2 tries per account. Your "5 attempts" rule never triggers. ❌ Lockouts backfire. Now attackers can lock real users out on purpose. ✅ The real fix: decide earlier. Put a cheap risk check in front of the expensive one, and only spend CPU on requests that look real. What the risk check looks at: 🔹 TLS fingerprint: a real iPhone app and a Python script connect differently, even if both claim to be an iPhone 🔹 Failure rate: a client failing most of its logins is suspicious 🔹 Known device: have we seen this device before? No single signal is enough, so you combine them and respond in proportion: 🟢 Low risk → straight through 🟡 Medium risk → CAPTCHA 🔴 High risk → dropped before it touches bcrypt Real users barely notice. Bots get expensive. 💸 Interview answer in one line: score each request cheaply, challenge the doubtful ones, and protect the slow, expensive step behind them. 📌 Save this for your next system design interview 💬 Comment "SECURITY" if you want the next one on rate limiting ➕ Follow for more backend concepts explained visually Hashtags: #systemdesign #softwareengineering #backend #cybersecurity #codinginterview techinterview programming developer bcrypt webdevelopment learncoding computerscience botprotection apidesign tech
