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 ## Coding Challenge #127 - Tmux DevFeed: [Coding Challenge #127 - Tmux]() Original publisher: [Read original article]() Author: John Crickett Published: 2026-07-18T08:00:26Z Content type: tutorial Language: en Sources: [Coding Challenges]() Topics: [Code Challenge](), [systems](), [Programming](), [Terminal](), [Unix](), [Shell]() Tags: [coding](), [programming](), [shell](), [ssh](), [systems](), [terminal](), [the-challenge](), [unix]() ### AI overview A coding challenge asks readers to build a simplified version of tmux, a terminal multiplexer.

It discusses behavioral reimplementation, added features, copyright concerns, and the distinction between copying ideas or behavior and copying source code. ### Source excerpt Those who cannot remember the past are condemned to repeat it. A sentence that I never really liked, and what is happening with AI, about software projects reimplementations, shows all the limits of such an idea. Many people are protesting the fairness of rewriting existing projects using AI. But, a good portion of such people, during the 90s, were already in the field: they followed the final part (started in the '80s) of the deeds of Richard Stallman, when he and his followers were reimplementing the UNIX userspace for the GNU project. The same people that now are against AI rewrites, back then, cheered for the GNU project actions (rightly, from my point of view - I cheered too). Stallman is not just a programming genius, he is also the kind of person that has a broad vision across disciplines, and among other things he was well versed in the copyright nuances. He asked the other programmers to reimplement the UNIX userspace in a specific way. A way that would make each tool unique, recognizable, compared to the original copy. Either faster, or more feature rich, or scriptable; qualities that would serve two different goals: to make GNU Hurd better and, at the same time, to provide a protective layer against litigations. If somebody would claim that the GNU implementations were not limited to copying ideas and behaviours (which is legal), but "protected expressions" (that is, the source code verbatim), the added features and the deliberate push towards certain design directions would provide a counter argument that judges could understand. He also asked to always reimplement the behavior itself, avoiding watching the actual implementation, using specifications and the real world mechanic of the tool, as tested manually by executing it. Still, it is fair to guess that many of the people working at the GNU project likely were exposed or had access to the UNIX source code. When Linus reimplemented UNIX, writing the Linux kernel, the situation was somewhat more compli ## Redesigning my microkernel from the ground up DevFeed: [Redesigning my microkernel from the ground up]() Original publisher: [Read original article]() Author: January Published: 2026-01-12T00:00:00Z Content type: opinion Language: en Sources: [Drew DeVault]() Topics: [systems](), [Kernel](), [kernels](), [Development](), [Code](), [Unix]() Tags: [code](), [cpu](), [development](), [kernel](), [kernels](), [operating-systems](), [os](), [scheduler](), [systems](), [unix]() ### AI overview The author explains why the Helios microkernel project was abandoned after design and implementation problems, and describes starting Hermes from scratch while reusing selected code from Helios and Bunnix. Hermes is not yet feature-complete, but the author says it has a more robust design and supports symmetric multiprocessing. ### Source excerpt As you may recall, circa 2022-2023 I was working on a microkernel written in Hare named Helios. Helios was largely inspired by and modelled after the design of seL4 and was my first major foray into modern OS development that was serious enough to get to a somewhat useful state of functionality, with drives for some real hardware, filesystems, and an environment for running user programs of a reasonable level of sophistication. Helios development went strong for a while but eventually it slowed and eventually halted in a state of design hell. Since Helios was my first major OS project at this scale and with this much ambition, the design and implementation ended up with a lot of poor assumptions that made it a pretty weak foundation for building a complete OS upon. In late 2023 I more or less gave up on it and moved my OS development work out of the realm of writing code and back into the realm of thinking really hard about how to design operating systems. What followed was a couple of years of design thinking, developing small scale design experiments, and doing deeper research into prior art - reading papers and studying existing kernels. It was also during this period that I wrote Bunnix, a working Unix clone, motivated in part by a desire to gain some first-hand experience working in the design and implementation of Unix-style operating systems - a fertile environment for learning a lot of the nuts and bolts of OS implementations by working against a complete and proven design. In August I was finally prepared to have another go. I decided to start over from scratch, importing and adapting and rewriting code from Helios and Bunnix on an as-needed basis to speed things up, and writing from scratch anything where the lessons learned in hindsight outweighed the benefits of adapting existing code.1 The result is Hermes. Hermes has not yet reached feature parity with Helios, lacking some IPC features and an aarch64 port, but already it's significantly more robust and ## Testing word counting code using KLEE and CBMC DevFeed: [Testing word counting code using KLEE and CBMC]() Original publisher: [Read original article]() Published: 2025-12-24T23:00:00Z Content type: tutorial Language: en Sources: [Dennis Yurichev]() Topics: [Testing](), [C](), [Code](), [Linux](), [Unix]() Tags: [c](), [code](), [linux](), [testing](), [unix](), [verification]() ### AI overview This article examines a rewritten word-counting exercise from The C Programming Language using buffer input instead of console input.

It also covers selecting the installed shell, locating KSH packages, accessing documentation, and the relevance of KSH for legacy Unix scripting and system administration. ### Source excerpt Installing KSH (KornShell) on FreeBSD can be done with either FreeBSD ports or the pkg command. The ports collection will download the KSH source code, compile it, and install it on the system. The pkg method is easier, and it will download a pre-compiled binary package. Hence, it is recommended for all users. KornShell (KSH) has a long history, and many older Unix systems and scripts rely on it. As a result, KSH remains relevant for maintaining and supporting legacy infrastructure. Large enterprises, especially those with established Unix-based systems, continue to use KSH for scripting and system administration tasks. Some industries where KSH is still commonly used include finance and telecommunications. While Bash has become the dominant shell in many Linux distributions, KSH still holds a significant presence in Unix-like environments, particularly in legacy systems. Therefore, installing KSH and practicing with it is worthwhile if you plan to work in such environments.

It covers pattern and hold buffers, standard input and output, regular expressions, editing commands, and file-saving behavior. ### Source excerpt Sed is an acronym for "stream editor." A stream refers to a source or destination for bytes. In other words, sed can read its input from standard input (stdin), apply the specified edits to the stream, and automatically output the results to standard output (stdout). Sed syntax allows an input file to be specified on the command line. However, the syntax does not directly support output file specification; this can be achieved through output redirection or editing files in place while making a backup of the original copy optionally. Sed is one of the most powerful tools on Linux and Unix-like systems. Learning it is worthwhile, so in this tutorial, we will start with the sed command syntax and examples.
