In a wide-ranging conversation with Verizon open-source officer Dirk Hohndel, 'plodding engineer' Linus Torvalds discussed where Linux is today and where it may go tomorrow.

Curious exactly what happens when you run a program on your computer? Learn how multiprocessing works, what system calls really are, how computers manage memory with hardware interrupts, and how Linux loads executables.

The article discusses a bug in the OS X kernel related to how profiling signals are delivered in multithreaded processes. It explains that the kernel incorrectly sends the SIGPROF signal to the entire process instead of the specific running thread. The author outlines a fix involving a small edit to the kernel code to ensure the signal is sent to the correct thread.

Essential information for programming in the OS X kernel. Includes a high-level overview.

The process of starting a new program on Linux involves using the fork and exec system calls. Fork creates a clone of the current process, while exec replaces that clone with the new program to be executed. The new process inherits most attributes from its parent, with memory being shared through copy-on-write to optimize performance.

Xv6 is a teaching operating system developed by MIT for their operating systems course. It is based on Unix V6, written in ANSI C, and runs on Intel x86 machines. The xv6 source code is available on GitHub and is used in lectures to teach operating system concepts.

The text discusses various techniques used in exploit development, particularly focusing on targeting the Windows kernel. It mentions concepts like Hypervisor-Protected Code Integrity (HVCI) and how exploits can manipulate memory to execute attacker-controlled code in kernel mode. The text also delves into details like leaking kernel-mode memory, constructing ROP chains on the kernel-mode stack, and utilizing functions like NtQuerySystemInformation to escalate privileges and perform malicious actions in the system.

This text explains how to create an operating system by first cross-compiling and using existing technology. It guides you through writing a kernel in C or C++, creating a bootloader, and linking the kernel for x86 systems. Following these steps ensures your operating system can be loaded and executed correctly.

The UNIX Time-Sharing System is a versatile operating system with unique features. It runs on Digital Equipment Corporation computers and emphasizes simplicity and ease of use. UNIX has been widely adopted for research, education, and document preparation purposes.

Terry A. Davis, an American electrical engineer and programmer, created TempleOS, a public domain operating system. Despite his mental health challenges, Davis gained an online following for his unique work and beliefs. His legacy continues to be remembered through documentaries and online discussions.

This blog series provides tutorials on creating a small operating system in the Rust programming language. Each post includes all the necessary code and is accompanied by a corresponding GitHub repository. The series covers topics such as creating a Rust executable without linking the standard library, building a bootable disk image, implementing VGA text mode, performing unit and integration testing, handling CPU exceptions, setting up the interrupt descriptor table, implementing paging and heap allocation, and exploring cooperative multitasking and the async/await feature of Rust. The posts also include status updates and information on supporting the author.
