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.

Google wants your ID to ship Android apps

In August 2025 Google announced that, starting in 2027, every Android app developer has to register centrally with Google before their software can be installed on a certified Android device. Registration means paying a fee ($25), accepting Google's terms, handing over a government-issued ID, providing evidence of your private app-signing key, and listing every application identifier you ship now and intend to ship later. The requirement does not stop at the Play Store. It covers apps distributed through F-Droid, apps passed directly between people, and builds that a hobbyist makes for personal use. A developer who does not register has their apps blocked on Android devices worldwide. The keepandroidopen.org campaign organizing the opposition is counting down to the first enforcement, which it puts roughly 70 days out. What the check actually verifies Google is verifying the developer…

My AI Coding Workflow, v3

My AI coding workflow changes every few months, so I give it version numbers. New tools ship, models get better, and steps that needed hand-holding last spring now run on their own. v1 was plan mode and a hand-written SPEC.md. v2…

Opera's Bet on Bespoke Browsers Could Actually Pay Off

Opera Neon is the company’s testbed for an agentic web, but it’s just one piece of a broader strategy. After speaking with the company about its multi-browser approach, I’m intrigued by where this could go. "We don't have all the answers." That's how Jan Standal, Opera’s senior vice president of marketing and communications, replied to a question I asked about the future of the web during a recent conversation. But rather than inject its mainline browser with a hodgepodge of ideas that might never be relevant, Opera says it's building several experimental browsers for targeted audiences. Read on for how Opera is building browsers in volatile times, along with details about its approach to Neon. I still don’t find Neon all that useful after testing it, but I do think Opera has the right idea about making products for specific types of users. He further explains that because Opera is more…

John Backus - the Father of Fortran

Creating the first compiler went hand-in-hand with the task to creating the first high-level computer language. You can argue that this was Fortran or some other language, but the fact of the matter is that Fortran was the…

Next.js `headers()` and `cookies()` in 2026: Dynamic APIs, Opt-Out Semantics, and the Static Rendering Traps Teams Hit

This article was written with the assistance of AI, under human supervision and review. The fix requires explicit opt-out: isolate dynamic reads behind Suspense boundaries, adopt Partial Prerendering (PPR) to separate static shells from dynamic slots, or configure route segments with force-dynamic and force-static directives. Each approach trades convenience for control. Boundaries add markup. PPR demands architectural planning. Route configs scatter intent across files. The decision happens automatically. Developers write components that read cookies for authentication or headers for locale detection. The compiler detects these API calls and marks the containing segment dynamic. No configuration file declares the intent. No build output highlights the change. The route shifts from prerendered static to request-time dynamic without ceremony. This component reads a theme cookie and the…
