Added a New Question: How TO Design Perplexity: a RAG search system with citations. User enters a question, - the system retrieves relevant web/docs content, ranks the best sources, generates an answer, and attaches citations to the exact supporting passages. Key areas to discuss: query understanding, retrieval, ranking, chunking, source credibility, streaming response, citation mapping, caching, hallucination control, and fallback states. A good design should make the answer fast, traceable, and trustworthy. hellofrontend.com/system-design #HelloFrontend #SystemDesign #RAG #AIart️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️️ #frontend #ai #layoff



AI Reshapes Tech, So Does Your Preparation Big tech is changing. The roles being automated first are the ones that require the least depth. Layoffs and “restructuring around AI” are signs that companies are shifting what they value—not that tech careers are over. If you’re a frontend engineer, here’s what still matters: • Being able to build real UI components under pressure. LeetCode questions don’t prepare you for machine‑coding rounds in React . • Mastering the architecture behind high‑scale frontends—state management, caching strategies, and UI system design . • Understanding browser internals, async rendering, and performance so you can optimize beyond just code syntax . • Knowing how to integrate AI patterns like streaming chat, agent tracing, and RAG into real products . That’s why I built HelloFrontend. It’s not a bunch of copy‑pasted questions—it’s a complete prep loop with six tracks: JavaScript, machine coding, system design, conceptual depth, web fundamentals, and a new AI track . You practice in a real browser editor, run tests instantly, and track your attempts, notes, and weak areas . AI isn’t going to eliminate the need for thoughtful engineers. It’s going to amplify those who can design great UIs and integrate intelligent features. Don’t chase headlines. Build skills that compound. If you’re prepping for interviews at AI‑first companies, check out HelloFrontend. It’s free to start, and it’s designed for the real loops companies actually run - hellofrontend.com #HelloFrontend #FrontendInterview #WebDev #JavaScript #MachineCoding #SystemDesign #AI #TechCareers #AIJobs #Upskill


🇺🇸 Jamie Dimon, CEO of JPMorgan Chase, said it out loud: Your kids will work 3.5 days a week. Live to 100. AI is going to cure cancer, stop car crashes, make new materials, save lives. "Life will be better." He's not a tech bro dreaming out loud. This man runs the money. Video: @clashreport
