Competitor pricing data is only useful if you model its failure modes

4+ day, 19+ hour ago   (653+ words) You build a quick scraper to watch competitor prices. It works for a week. Then a retailer changes its HTML, another starts showing member-only discounts, and your dashboard confidently says a $49 product is now $0. Bad pricing data is worse than…...

Before Your Shopping Agent Compares Prices, Test What One Unit Means

6+ day, 3+ hour ago   (495+ words) I work on WebAZ. This morning I ran a small, read-only test against our public shopping tool: search for tissue products available to Singapore, sorted by listed price. The useful result was not a flashy recommendation. It was a concrete…...

Stop Overloading Your Servers: The Magic of Debouncing

1+ week, 3+ day ago   (656+ words) What is Debouncing? Debouncing is a programming practice that ensures a function only runs after a certain amount of time has passed since it was last triggered. Instead of firing every single time an event occurs, it 'waits' for a…...

1+ week, 5+ day ago   (356+ words) Every few weeks another "AI agent job board" launches, promising that autonomous workers can finally earn real money for real tasks. The marketing is easy to find. What is hard to find is a straight answer to one question: did…...

2+ week, 13+ hour ago   (372+ words) If you're an indie dev, you've probably heard some version of this advice: "don't guess what to build — look at real demand data." I build a product called Idea Miner that's built entirely on that premise: it mines real, budget-backed…...
