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.
Both are served at vendor list price; full pricing is on the pricing page. Look at the last two rows: those are two genuinely different philosophies of cache billing, and they are the only source of difference in your bill. Anthropic's model is "expensive write, very cheap read." OpenAI's is…
Drop a long PDF into a chat on your Linux PC, ask about it, and get answers that cite the page. Click a page chip to open the PDF there. Page citations arrived in 0.0.55. In older builds a long attachment could end the reply with…
In commit c51b980a of the Quake III source tree, he replaced the infamous magic constant 0x5f3759df with a hardware SSE rsqrtss instruction. Sixteen lines of legendary, dark-arts floating-point bit hacking—accompanied by the immortal comment // what the fuck?—were struck down in a single routine commit. Every git repository on earth…
Most of the code I ship now is typed by an agent. I write the spec, Claude Code writes the diff, the checks run, and I read what came back. That changed which of my skills earn their keep. Typing speed stopped mattering…
You open a food delivery app, tap a restaurant and add a biryani to your cart. Then you press Pay. A spinner shows, and a moment later you see "Order placed." Two different jobs happened there. One team built the screen you tapped. Another team wrote the code that checked…
Before changing code, we ran Lighthouse against a production build (`next build` + `next start`), not `next dev`. Dev mode inflates JavaScript cost and hides image optimisation. Mobile emulation matters: most agency traffic lands…
Single-page applications load one HTML page and then update the content dynamically as users interact. No full browser reloads occur, and interfaces built this way often feel closer to desktop software than to conventional…
When something breaks, my worst instinct is to start changing things. This is the checklist I use to override that instinct, illustrated with real bugs from my own projects. If I can't make it fail on demand, I'm guessing. Before touching any code, find the smallest sequence of steps that…
C is still, after all these years, a good language to learn. It is simple and close to the machine hardware and this makes it a good first language. The only problem is getting started, which this article makes easy. Also see the…
You can't get far in creating C programs without using functions. The good news is that in C functions are simple and efficient and there is no reason not to use them. In this chapter we look at functions, parameters…
