# SLUG Meetup - Arch Linux

<br>

## Introduction to Arch Linux. What is it? What are its pros/cons?

> Speaker: Calvin Kim

\ <br>

### 1. Intro

#### Distro

: A Linux Distribution

<br>

#### Package Manager

: manages the packages

​ == app store

\ <br>

### 2. Arch Linux's Philosophy

* guides you little
* gives you (very well) build system only

  <br>

#### History

* CRUX
* No GUI installation
* Minimalist
* does not hide anything cause abstraction and hiding is never a good thing

  -> No handling

<br>

#### Design

* Everything is customizable (beside the kernel..haha)
* There is no default setting for Arch
* ABS -Arch Build System
* Collection of different things for arch

\ <br>

### 3. Four things base for Arch

#### 1) `PKGBUILD`

: Bash script -> literally a script

1. Link to source code
2. How to build the code

-> used as a guide for other package managers

<br>

#### 2) `makepkg`

: build system -> reads PKGBUILD

<br>

​ ----> *those two are the fundamentals*

<br>

#### 3) `pacman` == apt

: package manager

* manages all the programs on your Arch

<br>

#### 4) `AUR (Arch User Repository)`

​ : a repository maintained by Arch User group

* no official support tho
* has every open source software

\ <br>

#### `+` Arch Wiki

* the most complete wiki!!!!
* the most up-to-date
* specific laptop quirks
* driver configuration
* linux hacking

  \ <br>

### 4. Why do we have to use Arch Linux?

1. Bleeding edge

   : you'll have the latest one because it stays as close to the upstream
2. AUR

   : most complete package manager out there
3. Community Support

   : support by community equals that of Ubuntu

\ <br>

### 5. Tips/Tricks

1. Use `manjaro`

   : Arch based distro with GUI installation
2. sudo pacman `-Syu` a lot

   : updates are REALLY fast so....
3. Bug the community!

\
\ <br>

#### `+` looked up after the meetup

<br>

1. `mosh`

* Remote terminal application that allows **roaming**, supports **intermittent connectivity**, and provides intelligent **local echo** and line editing of user keystrokes.
* Mosh is a replacement for interactive SSH terminals. It's more robust and responsive, especially over Wi-Fi, cellular, and long-distance links.
* Mosh is free software, available for GNU/Linux, BSD, macOS, Solaris, Android, Chrome, and iOS.

<br>

2. `tmux`

* **tmux** is a [terminal multiplexer](https://en.wikipedia.org/wiki/Terminal_multiplexer) for [Unix-like](https://en.wikipedia.org/wiki/Unix-like) [operating systems](https://en.wikipedia.org/wiki/Operating_system).
* allows multiple [terminal](https://en.wikipedia.org/wiki/Computer_terminal) sessions to be accessed simultaneously in a single window.
* useful for running more than one [command-line](https://en.wikipedia.org/wiki/Command-line_interface) program at the same time.
* It can also be used to detach [processes](https://en.wikipedia.org/wiki/Process_\(computing\)) from their controlling terminals, allowing [SSH](https://en.wikipedia.org/wiki/Secure_Shell) sessions to remain active without being visible.
