A detailed guide explains how to build a TCP/IP stack from scratch, focusing on implementing Ethernet and ARP protocols in userspace Linux. The implementation uses TUN/TAP devices for intercepting network traffic and demonstrates successful ARP request handling, serving as an educational resource for deep network programming.
A technical comparison between Fuchsia's component framework and Linux container solutions, highlighting their similarities in blob fetching, filesystem isolation, and process namespacing. The presentation explores how different use cases and requirements lead to distinct strengths in each system, focusing on their key technological divergences.
A detailed analysis of the Intel Pentium's floating-point multiplier reveals a complex ×3 circuit containing around 9,000 transistors, utilizing base-8 multiplication for improved performance. The circuit combines advanced techniques like carry lookahead, Kogge-Stone addition, and carry-select addition to maximize speed and efficiency.
A firsthand account of Linux's creation and early development by Lars Wirzenius, who witnessed Linus Torvalds' journey from writing a simple multitasking program to creating the Linux kernel in 1991. The kernel evolved from displaying alternating As and Bs on screen to becoming a global powerhouse running on billions of devices, including Mars rovers.
An in-depth guide demonstrates how to netboot Windows 11 using iSCSI and iPXE, enabling Windows to run from a NAS instead of local storage. The solution allows gaming on Windows while maintaining Linux as the primary OS, providing a practical workaround for AAA games that restrict virtual machine usage.
A detailed analysis of a bug in HyperQueue where tasks were unexpectedly terminated after 10 seconds due to an interaction between tokio thread management, PR_SET_PDEATHSIG, and process spawning optimization. The bug emerged from moving process spawning to a worker thread, causing processes to receive SIGTERM when tokio cleaned up idle threads.
A comprehensive chronicle of OpenBSD's software innovations and security features, detailing the project's significant contributions to operating system security, including privilege separation, ASLR, stack protection, and numerous system hardening measures.
A developer explores building a modern disk image for Rock Pi 4 using Yocto, incorporating CUPS and Docker while leveraging Yocto's advanced SBOM generation capabilities. The process demonstrates how to create custom Linux distributions for embedded systems, with detailed instructions for setup and configuration. The guide addresses common challenges in maintaining up-to-date software for Chinese SBCs while highlighting Yocto's sophisticated approach to dependency tracking and SBOM generation.
A researcher successfully resurrected a 1972 UNIX V2 'Beta' version from DMR tapes, featuring both V1 and V2 compatibility and increased core size to 16 KiB. The system demonstrates functionality with basic commands and C compilation, though it requires specific emulation conditions to operate.
Lennart Poettering's FOSDEM keynote discusses systemd's 14-year evolution from an init system to a comprehensive suite of Linux OS building blocks, highlighting its growth to 150 binaries, adoption by major distributions, and future focus on boot integrity, IPC improvements, and image-based deployments.
