ThePrimeTime·1yLinux Is Obsolete
In 1992, a heated discussion occurred on the topic of Linux being an obsolete and inadequate operating system as compared to microkernel based systems like Minix. Linus Torvalds, the creator of Linux, defended his project against such criticism, emphasizing that Linux was a hobby project, freely available, and designed for real-world usability. He pointed out that the limitations of Minix, both in terms of performance and multitasking, made Linux a better choice despite its monolithic nature. This conversation also highlighted the broader debate between microkernels and monolithic kernels, as well as the importance of accessibility and practicality in software adoption.
The Register·1yTechie pulled all-nighter that turned into an all-weekender
A techie named Alejandro, working for a multinational company in the early 1990s, pulls an all-nighter for a mainframe migration project. While cleaning up after the task, he accidentally wipes the entire system using the rm -rf command due to fatigue. Fortunately, he manages to recover the system using backup tapes and completes the job before Monday morning, avoiding termination.
Awesome Go·1yStarting Systems Programming, Pt 1: Programmers Write Programs
The post introduces the fundamentals of systems programming, covering essential topics such as bit manipulation, parsing, filesystems, input/output, syscalls, memory management, and signals. The focus is on writing multiple programs from scratch to understand the basics of programming deeply. Numerous exercises are provided to practice these skills, and the code examples are primarily in Go, with some Bash scripts.
