This is my first Arch install and I keep forgetting or using unsafe pacman commands, so I made a thing.

Arch's philosophy is to be modular, give you control over everything, and allow you to shoot yourself in the foot every other day until you run out of toes.

This guide is meant to be used as a quick reference and prioritizes safe, sane defaults, but you should read the pacman docs first. They're a quick read, and will save you some pain later.

Pacman and Aur

Pacman only works with official repos - unofficial repos are listed in aur, the Arch Linux Repository. It's common to use yay, a wrapper that allows you to easily use both aur and the official repository:

When should you use DateTime and when should you use Time?

It's a common misconception that [William Shakespeare][1] and [Miguel de Cervantes][2] died on the same day in history - so much so that UNESCO named April 23 as [World Book Day because of this fact][3]. However because England hadn't yet adopted [Gregorian Calendar Reform][4] (and wouldn't until [1752][5]) their deaths are actually 10 days apart. Since Ruby's Time class implements a [proleptic Gregorian calendar][6] and has no concept of calendar reform then there's no way to express this. This is where DateTime steps in:

>> shakespeare = DateTime.iso8601('1616-04-23', Date::ENGLAND)
=> Tue, 23 Apr 1616 00:00:00 +0000
>> cervantes = DateTime.iso8601('1616-04-23', Date::ITALY)
=> Sat, 23 Apr 1616 00:00:00 +0000

$mod refers to the modifier key (alt by default)

General

startx i3 start i3 from command line
$mod+<Enter> open a terminal
$mod+d open dmenu (text based program launcher)
$mod+r resize mode ( or to leave resize mode)
$mod+shift+e exit i3

Give me back my sanity

One of the many things I do for my group at work is to take care of automating as many things as possible. It usually brings me a lot of satisfaction, mostly because I get a kick out of making people's lives easier.

But sometimes, maybe too often, I end up in drawn-out struggles with machines and programs. And sometimes, these struggles bring me to the edge of despair, so much so that I regularly consider living on a computer-less island growing vegetables for a living.

This is the story of how I had to install Pandoc in a CentOS 6 Docker container. But more generally, this is the story of how I think computing is inherently broken, how programmers (myself included) tend to think that their way is the way, how we're ultimately replicating what most of us think is wrong with society, building upon layers and layers of (best-case scenario) obscure and/or weak foundations.

*I would like to extend my gratitude to Google, StackOverflow, GitHub issues but mostly, the people who make the

Once upon a time there was a user that wanted to install firefox.

The user tried to do pacman -S firefox but it didn't work. The all mighty pacman reported that firefox-3.2.4-1.i686.pkg.tar.gz could not be found on his mirror. So the user tried pacman -Sy firefox. It worked and the user rejoiced since he could once again go and troll /h/.

But all was not good. The user had made a grave error!

See, when the user told the almighty pacman to -Sy firefox, pacman did

Your class can be no longer than 100 lines of code.
Your methods can be no longer than five lines of code.
You can pass no more than four parameters and you can’t just make it one big hash.
When a call comes into your Rails controller, you can only instantiate one object to do whatever it is that needs to be done. And your view can only know about one instance variable.

You can break these rules if you can talk your pair into agreeing with you.
