### #LinuxForDevs ### @RogerCreasy

## Why Choose Linux?

* 83.1% of respondants on Stackoverflow's 2019 survey said Linux is their most loved platform<!-- .element: class="fragment fade-up" data-fragment-index="1" --> * 25.3% use Linux as their primary OS<!-- .element: class="fragment fade-up" data-fragment-index="2" --> * Flexibility - mold your system to match your needs and workflow<!-- .element: class="fragment fade-up" data-fragment-index="3" --> * Stay up to date, major updates are free<!-- .element: class="fragment fade-up" data-fragment-index="4" --> * Lightweight - power on less robust, less costly hardware<!-- .element: class="fragment fade-up" data-fragment-index="5" --> * You have access to everything, the code, the systems, everything<!-- .element: class="fragment fade-up" data-fragment-index="6" --> * Tinkerers love Linux<!-- .element: class="fragment fade-up" data-fragment-index="7" -->

Your system really is YOUR system. Configure it the way YOU want

#### I asked devs on Twitter why they use Linux. Here is what some said. * Speed. Easy to install things. Once you use i3 it's hard to use anything else.<br> I work with linux servers and having my os related to that helps. Windows for development is terrible. I'd probably be able to stand a mac though but windows is out of the question.<!-- .element: class="fragment step-fade-in-then-out" --> * Because it does exactly what I say it to do and is super configurable, most of all @Docker works as expected. ;)<!-- .element: class="fragment step-fade-in-then-out" --> * I've been turned off since #windows8 and switched to @ubuntu FT several years ago. It's what most closely mimics my VPS Server when doing development. And, I <3 working on cli<!-- .element: class="fragment step-fade-in-then-out" --> * Native docker is the reason<!-- .element: class="fragment step-fade-in-then-out" --> * I use @ubuntu with i3 for the configurability. I don't want to do things the Apple way or the Microsoft way. I want to do them my way.<!-- .element: class="fragment step-fade-in-then-out" --> * I use Linux because the Windows and osx interaction paradigms are not designed for power users and not configurable.<br> But I also use Linux in no small part due to the fact that Linux is owned by all of humanity.<!-- .element: class="fragment step-fade-in-then-out" -->

### "Linux is owned by all of humanity" ## WOW!<!-- .element: class="fragment fade-up" data-fragment-index="1" --> I LOVE the open source philosophy!<!-- .element: class="fragment fade-up" data-fragment-index="2" -->

## Linux Negatives
Myths, Legends, Truths

### Finding Hardware Drivers is a Problem * Not all hardware manufacturers write drivers for Linux<!-- .element: class="fragment fade-up" data-fragment-index="1" --> * Before buying or installing hardware make sure it is compatible with Linux<!-- .element: class="fragment fade-up" data-fragment-index="2" --> <aside class="notes"> Later on in the presentation we will see how to test a system before installing Linux </aside>

### Linux is difficult to use ### Linux is for Geeks * Linux is no more difficult than Windows or Mac. It is just different.<!-- .element: class="fragment step-fade-in-then-out" --> * In case anyone didn't know it - We ARE geeks<!-- .element: class="fragment step-fade-in-then-out" --> <aside class="notes"> Things are different in linux. Try to recall using your current system for the first time. Learning Linux now will be easier than that was. I set up a livestreaming system for my church. Users are totally non-techincal, Windows users. They didn't know they weren't on Windows. </aside>

### Linux is not for gamers * I am not a gamer<!-- .element: class="fragment step-fade-in-then-out" --> * This point may hold water<!-- .element: class="fragment step-fade-in-then-out" --> * There are games available for Linux<!-- .element: class="fragment step-fade-in-then-out" --> <aside class="notes"> There are some game resources listed in my Linux resources list </aside>

### You must learn to use the command line to use Linux * The command line is very powerful.<br>There is much you can do using it.<!-- .element: class="fragment step-fade-in-then-out" --> * You do not HAVE to use the command line.<!-- .element: class="fragment step-fade-in-then-out" --> <aside class="notes"> I am going to cover the command line in the next section </aside>

### Linux doesn't have the applications I need * There are 1000s of applications available<!-- .element: class="fragment step-fade-in-then-out" --> * Switching to any OS will involve finding<br> replacements for some software<!-- .element: class="fragment step-fade-in-then-out" --> * There are alternatives for most applications<!-- .element: class="fragment step-fade-in-then-out" --> <aside class="notes"> I do many different things, all from within Linux - PHP, Golang, and web development; Music Composition; Light graphics work; video I set up a live streaming system for my church - entirely in Linux. If you move from Windows to Mac, or Mac to Windows, there will some software that you have to find a replacement for. Upgrading from Windows or Mac to Linux is no different. </aside>

### Don't fear the command line There are pros and cons to the command line <aside class="notes"> </aside>

### Command Line Cons * Unintuitive<!-- .element: class="fragment fade-up" data-fragment-index="1" --> * i.e. : sed -i "s/truck[s]*/bus/g" file2<!-- .element: class="fragment fade-up" data-fragment-index="2" --> * Not user-friendly for beginners<!-- .element: class="fragment fade-up" data-fragment-index="3" --> * Lacks the visual aspects of a GUI<!-- .element: class="fragment fade-up" data-fragment-index="4" -->

### Command Line Pros * Concise<!-- .element: class="fragment fade-up" data-fragment-index="1" --> * Efficient<!-- .element: class="fragment fade-up" data-fragment-index="2" --> * Powerful<!-- .element: class="fragment fade-up" data-fragment-index="3" -->

### The Command Line Gives You ## SUPERPOWERS!

### Commands in the Terminal are really just mini applications * Give some input<!-- .element: class="fragment fade-up" data-fragment-index="1" --> * Get output (or route the output to another command)<!-- .element: class="fragment fade-up" data-fragment-index="2" --> \

### Linux Distros A brief comparison
