A customer might have multiple calls, emails, meetings, product demonstrations, negotiations, and follow-ups. Somewhere along the way, important information gets scattered across CRM notes, meeting summaries, documents, and the salesperson's own memory. The result? Sales representatives spend valuable time reconstructing what happened before a meeting an...

Porting a working MySQL schema to PostgreSQL is rarely a find-and-replace. The SQL standard leaves enough room that the two engines disagree on quoting, types, upserts, and pagination — and most of the disagreements fail at runtime, not at parse time.

If HTML feels confusing, imagine you're building a house. You're standing on an empty piece of land. You have a vision of what you want the finished house to look like. Maybe you want beautiful colours. Comfortable furniture. Large windows. Smart lighting. Automatic doors. A modern kitchen. But there's a problem. You can't start with the decorations. You need a structure first. That simple idea can help you understand one of the most fundamental technologies o...

FieldMind is an AI-powered operational-memory agent designed to solve this problem by helping organizations remember what happened, learn from previous outcomes, ...

Hi HN, I’m Per, founder of Scrimba (YC S20). We’ve spent the last decade teaching people how to code with an HTML-based video format. We’ve now plugged an LLM into it, so that people can create explainer videos about anything. It’s called “Scrimba Explain”. To demo this technology for Hacker News, we built HN.watch.
