AI assistant: Here's your login page with OAuth2, biometric auth, a CAPTCHA, a password strength analyzer, dark mode, 47 dependencies, and a microservices architecture. You: "No... just a simple login page." AI: Got it. Working on ONE simple login page... [MESSAGE]: You've run out of tokens. Please upgrade to Pro ($99/mo) to continue—or wait until 2 PM tomorrow. You: "..." I've seen development gigs burn over $1,000 in just a couple of hours of "vibe coding". The #1 skill in the AI era isn't prompting. It's knowing what NOT to accept. Most devs blindly paste AI output. The best ones know when to say "no, simpler." 3 rules I follow: - Start with the simplest prompt. Add detail only when needed. - If the output surprises you, you under-specified. That's YOUR bug. - Treat AI like a junior dev: review everything, trust nothing. P.S. If you're learning AI or want to use it better—you will love my weekly newsletter (it's free). Make sure to subscribe to receive your letter

Rajan Vinod reposted thisRajan Vinod reposted thisChristopher Havens arrived in a maximum-security prison in Washington carrying the weight of a life defined by bad decisions—drugs, violence, and crime. By 2011, at thirty-one years old, his future looked brutally fixed. For most people, prison is where ambition ends and hope withers. For Christopher, prison gave him something he’d never had before: time. One day, a cellmate left behind a math textbook. Out of boredom more than curiosity, Christopher picked it up. Math had never been his strength. He had scraped through school and dropped out without direction. But alone in his cell, with long hours and nothing to distract him, he began working through the problems. Something unexpected happened. He asked the prison education program for more books. Then harder ones. He taught himself algebra. Then calculus. Then advanced topics most students never encounter without a university classroom. Night after night, he worked alone, filling pages with symbols and proofs. Eventually, he hit limits. Some concepts were too advanced to unravel alone. He needed guidance. So Christopher did something audacious: he wrote letters to professional mathematicians around the world, asking for help. Most never replied. But one mathematician answered: Umberto Cerruti from the University of Turin. He didn’t condescend. He challenged Christopher. He sent materials on number theory, one of mathematics’ most abstract and demanding fields, and assigned problems that would test even trained researchers. Christopher responded with pages of handwritten work—careful, rigorous, original. Later came the moment that stunned everyone. Christopher uncovered new insights into relationships within number theory that had eluded others. Cerruti shared the work with colleagues. They checked it. Verified it. It held up. In 2020, Christopher Havens’ research was formally published in Research in Number Theory, a respected peer-reviewed journal. A man serving decades in prison, with no college degree and no access to computers or university libraries, had contributed original, doctoral-level mathematics to human knowledge. The man who entered prison defined by violence discovered discipline, purpose, and a way to give back. Christopher went on to co-found the Prison Mathematics Project, mentoring incarcerated students around, helping them study mathematics. He continues his own research, tackling problems that challenge professional mathematicians. He won’t be eligible for release until 2036. Yet in many ways, he’s already free—free to think, to create, to contribute. Christopher Havens’ story isn’t an argument that crimes don’t matter. It’s proof that people are more than the worst thing they’ve done. That genius doesn’t require privilege. That education can unlock minds society has written off. The world should change how to think about punishment, education, and human potential. How many more discoveries are waiting—quietly—behind locked doors?

Rajan Vinod liked thisRajan Vinod liked thisWhat if AI could objectively evaluate how people perform in group discussions? Yesterday, I presented my capstone project at the iShowcase organized by the University of Arizona. I built an AI-Powered Student Behaviour Analysis System that analyzes group discussion videos using: • Computer Vision • Machine Learning • Large Language Models (LLMs) What it does: • Detects non-verbal behaviors (gaze, posture, gestures, emotions) • Computes attention, engagement, and discussion scores • Classifies performance using ML models • Generates structured AI-powered reports Why this matters: Most evaluations today are subjective. This system introduces a data-driven, unbiased, and scalable approach. Presenting this as an individual project and receiving real-time feedback was a great learning experience. Proud of what I built. #AI #MachineLearning #ComputerVision #LLM #DataScience #StudentAnalytics #iShowcase #UniversityOfArizona

This was BookMyShow's browser talking to not allowed scripts. 😤 Let me explain 👇 Booking tickets. DevTools open (as usual). Console shows: violates Content Security Policy directive: "connect-src" Calls going to Google Ads, DoubleClick, Criteo, Freshworks • Browser checked CSP • Domain not whitelisted → soft violation → request blocked CSP 101: Content Security Policy = HTTP response header that acts as a whitelist. It tells the browser exactly what's allowed: ``` Content-Security-Policy: script-src 'self' trusted.com; connect-src 'self' api.trusted.com; img-src 'self' cdn.trusted.com; ``` Anything outside this list? Blocked. No questions asked. Key directives: script-src → Where JS can load from connect-src → Where fetch/XHR/WebSocket can connect img-src → Allowed image sources frame-ancestors → Who can embed your site (clickjacking protection) default-src → Fallback for all What CSP prevents: → XSS attacks — Injected scripts won't execute → Data theft — Stolen data can't be sent to attacker's server → Clickjacking — Your site can't be embedded maliciously #ContentSecurityPolicy #WebSecurity
