Playwright Crawling Pipeline: Production Code Theory is over. Now we build. The Structure Collect → Filter → Store → Alert → Repeat Five steps in code. Step 1: Basic Collection Price Monitoring Example const { chromium } = require('playwright'); async function checkPrice() { const browser = await chromium.launch({ headless: true }); const page = await browser.newPage(); await page.goto('https://example.com/product/12345'); const price = await page.locator('.price').textContent(); const priceNumber = parseInt(price.replace(/[^0-9]/g, '')); await browser.close(); return priceNumber; } Key Points: headless: true → Background execution .locator() → Auto-wait included Always close browser Step 2: Filtering Logic const TARGET_PRICE = 50000; async function monitorPrice() { const currentPrice = await checkPrice(); if (currentPrice Step 3: Data Storage SQLite (Recommended) const ...

Building a Profit Pipeline with Playwright You've upgraded your engine. Now it's time to monetize. Crawling Is a Pipeline, Not a Tool Most people see crawling as "scraping data." But done right, it becomes: Data Collection ↓ Processing ↓ Analysis ↓ Auto Distribution ↓ Revenue Generation A system that runs 24/7. Three Real Revenue Models 1) Price Monitoring → Affiliate Revenue const price = await page.locator('.price').textContent(); if (price Structure: Track specific products on Amazon/Coupang. When price drops below target, auto-send Telegram/email with affiliate link. Key Points: Niche products have higher conversion rates 24/7 monitoring captures perfect timing Recurring purchases generate sustained revenue 2) Real Estate Listings → Brokerage Connection const newListings = await page.locator('.new-badge').all(); for (const listing of newListings) { saveAndNotify(price, location); } Structure:...

3 AM Alert: Your Crawler Stopped Again 3 AM. Slack notification: "Crawler failed." It worked perfectly last night. All tests passed. So why did it stop again? Staring at the error log, you ask yourself: "What did I do wrong?" You're Not Alone Countless developers face this exact frustration with Selenium: It worked yesterday, but not today Works locally, breaks on the server Increasing time.sleep(3) to time.sleep(5) doesn't help You end up building automation based on luck, not logic. The Real Problem This isn't about your skill. You're using the wrong engine. Just like car engines, browser automation tools have generations: Selenium = 1990s diesel. Reliable but slow and finicky Puppeteer = 2010s hybrid. Fast but limited to specific conditions Playwright = 2020s electric. Silent, fast, works everywhere Why Selenium Breaks Selenium communicates with browsers via HTTP. Every action re...

Why Forgetting Is Essential for AI Memory Most people assume that storing more is always better. But when building a memory system, I ran into something counterintuitive. The more you store without filtering, the less useful the system becomes. What happens when you store everything Important and unimportant information sit at the same level Noise increases with every search What actually matters gets buried You end up with a system that cannot retrieve anything reliably. How humans handle this Human memory works differently. Unimportant things fade naturally Old information becomes less vivid Only the core remains accessible This is why human memory stays functional over time. Memory is not stored. It is compressed. Forgetting is not deletion This is the key distinction. Forgetting does not mean erasing information. It means restructuring information density. The compression process looks like this: Full text Summary Core idea Keyword Af...

Why AI Cannot Remember Without Relationships Have you ever wondered: Why did the AI bring this up? The real issue AI does not fail to remember. It fails to connect. Scoring is not enough Importance helps Prioritization helps But something is still missing. How humans remember One idea triggers another Related memories surface together Context builds naturally The core difference Memory is not isolated. It is relational. How AI works today No relationships. What this causes Irrelevant results appear Context breaks Conversations feel disconnected Search vs Memory Search → finds similarity Memory → retrieves connections The solution Build relationships between memories. Relationship strength Strong links surface first Weak links surface later This defines retrieval order. Final takeaway AI does not lack memory. It lacks relational structure.

Why AI Cannot Remember What Matters When using AI, you notice something strange. It forgets important things, but repeats irrelevant ones. The real problem RAG is not memory. It is retrieval. What happens in practice Important information gets buried Less relevant data resurfaces Context keeps breaking The missing piece The problem is not storage. It is selection. How humans remember Important things last longer Frequently used things come up faster Old information fades away How AI works today Everything is treated equally. A different approach Importance Usage Recency Stability This creates priority. Before vs After RAG → everything is equal Memory system → prioritized structure The key shift Memory is not storage. It is a state that evolves over time. Final takeaway AI does not fail to remember. It lacks prioritization.

Why RAG Cannot Create “Memory” in AI I kept hitting the same problem. Why does AI keep repeating itself? The assumption was wrong At first, I believed this: “RAG will solve it.” But it didn’t. How RAG actually works Store data Search with vectors Retrieve similar items It looks good on the surface. But in reality It doesn’t know what matters It can’t separate signal from noise Old information still shows up The core problem RAG is not memory. It is similarity search. Limitations of similarity search Similar ≠ important Critical information gets buried No understanding of relationships What’s missing Time Importance Relational structure What this causes Important recent decisions disappear Old, less relevant data resurfaces The realization The problem is not retrieval. It is the memory structure. A different approach Importance-based retention Relation-based linking Time-based compression This...

Why Does AI Keep Forgetting? (And What I'm Building to Fix It) You notice this at some point. "Why do I have to explain this again?" The problem is simpler than it looks AI is smart. But it doesn’t remember. More precisely, it doesn’t manage memory. The limitation Most systems do this: Store conversations Store documents Search and re-read That’s not memory. That’s storage. The insight Memory is not storage. Memory is management. What I'm building Score-based memory Relation-based retrieval Progressive compression The difference Old way: Store everything Search everything Read everything New way: Keep what matters Forget what doesn't Read in order of relevance One line AI doesn’t lack memory. It lacks memory management. The next bottleneck of AI is not intelligence. It’s memory.

Why Developers Are Talking About Meta Harness The real difference is no longer the model itself. It is the system around it. The real problem with AI AI is powerful, but it is not naturally stable. It forgets context It changes answers across sessions It struggles with long, complex tasks It often breaks consistency in real projects What Meta Harness really means Meta Harness means designing the operating structure around AI. What information should be injected In what order it should be processed Which tools should be connected How outputs should be checked and recovered What developers are actually worried about How to preserve context How to keep outputs consistent How to connect multiple agents How to link AI with code, files, and execution How to recover when the workflow breaks Wrong approach vs right approach Wrong approach Relying only on chat Depending on human memory Running projects without structure...

When Thinking Becomes a System: The PSKE Engine 1. The Real Problem Was Memory Ideas disappear. AI context disappears. Execution resets. The core hypothesis was simple: “Documents are memory.” 2. What is the PSKE Engine? It is not a tool. It is a system that forces: Design Build Verify Record Nothing is allowed to exist outside this loop. 3. External Evaluation The system was reviewed externally. Key feedback: High consistency Strong execution logic Scalable architecture 4. Problems Identified Gap between operator and system Overly strict step rules Mismatch between execution and records 5. Iteration The system was refined: Architecture lock enforced Flexible execution mode added Record alignment improved Final Thought This is not software. It is an attempt to turn thinking into a system.

 Many AI business ideas look different: Healthcare, cosmetics, senior care, automation… But structurally, they are identical. As shown in the Medvi case: Did AI Really Build an $1.8B Company? - What Matthew Gallagher’s Case Actually Reveals The Pattern Pain → AI Compression → External Infrastructure → Delivery → Subscription Key Insight AI does not build businesses. 👉 It compresses execution. Real Question Can this structure generate recurring revenue? Conclusion There are not many AI businesses. 👉 There is only one structure applied to many markets.

1. The Idea That Became Reality Sam Altman once said that one day, a single person could build a billion-dollar company using AI. At the time, it sounded like a distant idea. But recently, a case in the U.S. made this concept feel much more real. Matthew Gallagher, founder of Medvi, reportedly started a telehealth business with just $20,000 and a very small team, reaching a run rate of $1.8 billion. However, since the company is private, these numbers should be understood based on media reports. 2. This Is NOT an AI Company If you think “AI built this company,” you're missing the point. Medvi is not fundamentally an AI company. It is a telehealth platform connecting users to GLP-1 weight-loss treatments. Medvi → marketing, onboarding, payments Doctors → medical decisions Pharmacies → fulfillment In short: Medvi is a demand engine 3. The Real Innovation Traditionally, this kind of business required: doctor networks pharmacy systems support teams...
