Specialized search for programming

Curated, developer-focused results

4Programming is a search engine built for programmers. It prioritizes technical relevance by combining multiple indexes, code-aware ranking, and AI systems. Use it to find code examples, documentation, libraries, tools, tutorials, and services — faster and with fewer irrelevant results than general-purpose search engines. Part of the 4SEARCH network of topic specific search engines.

Automatic Watermark Detection: What 500 Real Cases Changed

ClearPix engineering series · Part 21 We tested automatic watermark detection on 500 real AI-platform frames: editable-selection coverage rose from 75.8% to 95.0%. A separate 36-image human-mask evaluation still measured only 47.1% precision and 11.0% recall. Those results are not contradictory: locating a useful corner box is much easier than…

In my previous post, I rewrote my LINE research-planner bot from Python + Managed Agents to Go + ADK for Go, resulting in kkdai/line-research-bot-go. The user experience is unchanged: Around the same time, DeepSeek open-sourced deepseek-ai/dsh-superagent-prototype, a "super agent" prototype built on DeepSeek Harness (DSH).

Factoring using the quadratic formula

Factoring using the quadratic formula is the goal of this lesson. It is closely related to solving equations using the quadratic formula. Forgetting the a in front, or a sign. When x2 = −2, the factor is x − (−2) = x + 2, not x −…
