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.

Five days with eventferry " My SQL, SQL Server, MSK IAM, and a core that didn't move
42+ min ago (566+ words) Five days ago I posted I built a transactional outbox toolkit for Node. js " meet eventferry. The pitch was small and specific: Postgres + Kafka, the dual-write bug, a Goldilocks alternative between Debezium and a hand-rolled outbox. The roadmap was a…...
I built a security scanner for AI-generated code " here's what it found
49+ min ago (269+ words) Vibe coding is everywhere. You prompt Claude or Chat GPT, paste the output, ship it. Fast. But here's the problem nobody talks about: AI models consistently produce the same security mistakes, over and over. I spent the last few months…...

Disposable code is a psyop by people who don't maintain anything
38+ min ago (744+ words) There is an increasing trend on the internet stating that in the AI era, code longevity is "questionable if not problematic". The argument continues, "if AI can rewrite everything at 10x speed, why write long-lasting code at all?" I believe that's…...
Building repository-local memory for AI-assisted development
1+ hour, 3+ min ago (262+ words) I've been experimenting with a simple idea: what if coding agents had durable, repository-local memory instead of relying only on the current chat context? I open-sourced an early implementation called Agent Memory Layer. The goal is to preserve project intent,…...
Why Idempotency Is Critical in Modern Saa S Architectures
1+ hour, 3+ min ago (245+ words) Idempotency is one of the most important concepts in backend engineering, especially for Saa S platforms that rely on external APIs, webhooks, and asynchronous processing. Without idempotent operations, systems become unpredictable, hard to debug, and vulnerable to data corruption. What…...
