Streaming your Linux desktop to Youtube and Twitch via Nvidia's NVENC and VAAPI:

Considerations to take when live streaming:

The following best practice observations apply when using a hardware-based encoder for live streaming to any platform:

Set the buffer size (-bufsize:v) equal to the target bitrate (-b:v). You want to ensure that you're encoding in CBR mode.
Set up the encoders as shown:

Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.

Bucket setup

You can set your own custom Magento admin URL in:

System -> Configuration -> [ADVANCED] -> Admin -> Admin Base URL

Use Custom Admin URL = (YES)
Custom Admin URL = https://backend.domain.com

NOTE: Make sure you have added a ServerAlias directive to your virtual host configuration for backend.domain.com and that you have a SSL cert or wildcart setup for HTTPS traffic on that subdomain or you will lock yourself out the admin.

Rules for your .htaccess file to prevent duplicate urls and redirect directly to admin dashboard:

-#!/usr/bin/env node
-// Channel ID is on the the browser URL.: https://mycompany.slack.com/messages/MYCHANNELID/
-// Pass it as a parameter: node ./delete-slack-messages.js CHANNEL_ID
-// CONFIGURATION #######################################################################################################
-const token = 'SLACK TOKEN';
-// Legacy tokens are no more supported.
-// Please create an app or use an existing Slack App

	# The settings provided below are a starting point for a 8-16 GB RAM server with 4-8 CPU cores.
	# If you have different resources available you should adjust accordingly to save CPU, RAM & disk I/O usage.
	#

	# 0. For the server, use the "Docker" base image from the ImageHub (https://www.scaleway.com/de/imagehub/docker/)

	# 1. Install https://github.com/calavera/docker-volume-glusterfs
	# Alternatively, just download the prebuilt executable from https://gobuilder.me/get/github.com/calavera/docker-volume-glusterfs/docker-volume-glusterfs_master_linux-arm.zip
	apt-get -y install golang
	export GOPATH=~/go
	go get github.com/calavera/docker-volume-glusterfs
	mv go/bin/docker-volume-glusterfs /usr/local/bin/
