ARCH USER STAFF Daniel Griffiths (Ghost1227) ........... Editor ello, and thank you for picking up issue #1 of Arch User Magazine! While David Crouse (Crouse) .......... Contributor the vast majority of you probably know me (or have at least seen me H around the forums), I feel that I should take a moment to introduce myself. My name is Daniel Griffiths, and I am a 26-year-old independent contractor in Delaware, US. Throughout my life, I have wandered through various UNIX/Linux systems including (but not limited to) MINIX, RedHat, Mandrake, Slackware, Gentoo, Debian, and even two home made distributions based on Linux From Scratch. I finally found Arch in 2007 and instantly fell in love with its elegant simplicity. Some of our more attentive readers may note that Arch already has a monthly newsletter. With the existence of the aformentioned newsletter, what is the point of adding another news medium to the mix? Fear not, newsletter readers, I have no intention of letting Arch User Magazine take the place of the newsletter. In fact, Arch User Magazine and the newsletter are intended to fill two very different needs in the Arch community. -

A Brief Introduction to Linux
ABriefIntroductiontoLinux What is it? What can I use it for? Alexander B. Pacheco LTS Research Computing September 8, 2015 Outline 1 Introduction to Linux 2 Linux Components 3 Live Demo 2/25 Introduction to Linux Unix History I Unix was conceived and implemented in 1969 at AT&T Bell labs by Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. First released in 1971 and was written in assembler. In 1973, Unix was re-written in the programming language C by Dennis Ritchie (with exceptions to the kernel and I/O). The availability of an operating system written in a high-level language allowed easier portability to di↵erent computer platforms. The GNU Project, started in 1983 by Richard Stallman, had the goal of creating a “complete Unix-compatible software system” composed entirely of free software. 386BSD released in 1992 and written by Berkeley alumni Lynne Jolitz and William Jolitz. FreeBSD, NetBSD, OpenBSD and NextStep (Mac OSX) descended from this Andrew S. Tanenbaum wrote and released MINIX, an inexpensive minimal Unix-like operating system, designed for education in computer science Frustated with licensing issues with MINIX, Linus Torvalds, a student at University of Helsinki began working on his own operating system which eventually became the ”Linux Kernel” Linus released his kernel for anyone to download and help further development. 4/25 Unix History II Linus’s message to comp.os.minix on Aug 26, 1991 Hello everybody out there using minix - I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. -

It will not go into great depth for the sake of simplicity, but I will cite some other sources where you can find the more complicated explanations. Contents: Contents 1 Xmonad Tutorial for Beginning Beginners Documentation, Release 1.0 2 Contents CHAPTER 1 Introduction to using Xmonad The most important thing to understand about Xmonad is that it was created as a barebones, no distractions window manager. Because of this, there is a lot of customization and tweaking involved to get a working environment you are completely happy with. This may seem like a downside. However, consider the control one now has over their desktop environment – the sky’s the limit. -
Preliminary Report: Xmonad Practical Course – Contributing to an Open-Source Project Chair for Chair for Logic and Verification Technical University of Munich
Preliminary Report: XMonad Practical Course – Contributing to an Open-Source Project Chair for Chair for Logic and Verification Technical University of Munich Yecine Megdiche 1st of December 2020 1 Introduction and definitions XMonad is a “dynamically tiling X11 window manager that is written and configured in Haskell”. It is designed to be “lightweight, minimal, extremely customizable and crash-free”. This window manager is entirely usable with just the keyboard, with optional mouse support [1]. It is considered as one of the well known “real-world” software written in Haskell1. 1.1 Definitions • X11 Window System: The most used GUIs manager on UNIX-Like Operating Systems [2]. • Window Manager: The ArchWiki [3] defines a window manager as a “system software that controls the placement and appearance of windows within a windowing system in a graphical user interface.” – Tiling Window managers: Window managers who place win- dows in non-overlapping tiles are called tiling window managers, in contrast to stacking or floating window managers. [3] 1https://github.com/xmonad/xmonad/issues/93#issuecomment-298145660 1 2 XMonad: Short History and Motivation Spencer Janssen, one of the original authors of XMonad, used dwm2 as his window manager. Dwm is a tiling window manager, written and configured in C. That inspired him to create a similar project in Haskell, which he, Don Stewart, and Jason Creighton worked on. Brandon S. Allbery helped them make XMonad compliant with the “Inter-Client Communication Conventions Manual” rules defined by X11.[4] XMonad was announced on the 22nd of April 2007 by Spencer Janssen over at the Haskell-café mailing-list [5]. -
