But that operation of writing a minimal yet working Unix kernel for the 386 (at the beginning Linux was, let's say, mono-architecture) was something within the reach of many other programmers and students. Many in the sense of, I don't know, 0.1%, one in a thousand, one in ten thousand. Obviously most people are not able to do this kind of feat, but a lot of people are. If you look at Hacker News in the latest years, you'll see how many projects of kernels written in C, microkernels implemented from scratch, kernels written in Rust, kernels made in all sauces and manners, small Unix systems created vertically for the Raspberry Pi, operating systems for the ESP32 and so forth. Writing a kernel is not something within everybody's reach, but it is something that many can complete, if they put enough effort into it. Then, of course, not everybody will do it well. He is a genius programmer, without any doubt, so he did it better. And yet, of Linus there is only one. This implementative capacity of his, in fact, would not tell us much about him: what we should focus on, instead, is what happened later. ## He stopped writing code Among the maintainers of the famous open source projects, he was one of the very few that, very early in the history of the development of Linux, almost completely stopped writing code in order to concentrate on the leading of the project. On being the leader, the coordinator, the single mind holding the clarity about what the goals of the project must be, and so on. And this is a rare thing. Many maintainers (myself included, for a long time) continue instead to implement things directly, to not delegate much, an ## Creating an environmental logger - Part 1 DevFeed: [Creating an environmental logger - Part 1]() Original publisher: [Read original article]() Author: John Lee Published: 2026-07-15T00:00:00Z Content type: tutorial Language: en Sources: [Blog on Developer Portal]() Topics: [ESP32](), [ESP-IDF](), [Logging](), [Terminal](), [Internet of things](), [data](), [Library]() Tags: [article](), [blog](), [esp-idf](), [esp32](), [filesystem](), [how-to](), [i2c](), [iot](), [logging](), [sensor](), [vs-code]() ### AI overview This tutorial explains how to build an environmental logger with an ESP32-C61-Devkit-C, a DHT20 temperature and humidity sensor, and ESP-IDF.
