Similar to archive, but available to public. Focus on RSS and CDN.

RSS is simple with Cryogen via Tags. Can create a variety of channels, offering selection of readers.

Embed iframe. Sign content, or auth via YubiKey.

System login also possible in another episode: here.

Lots of hacking on this one, check the YT channel. Recent days.

Archival Project

Tue, 06 Mar 2018 00:00:00 +0000

Creates a fair use copy of online resources, such as your own YouTube playlists and videos.

Archived material is bundled into a maximally available static distribution format. At its most general and simple, one large incrementally built docker image can be created and distributed to a CDN.

Webserver

Sun, 04 Feb 2018 00:00:00 +0000

Simple website

(Not scalable)

Needs

Tiny Computer

Generate

Download and write RasPi SD card image

xz -e hypriot-1.7.0.img.xz

dd if=hypriot-1.7.0.img of=/dev/sda bs=128KB conv=fsync

When this completes, the card is ready to boot up the RasPi.

Insert SD card into RasPi, boot up, and configure
Create a new directionctory with index file and start script

cp tinydatacenter/starter-website.com mysite.com

cd mysite.com

nano index.html

Nano is a text editor similar to MS Word, except it runs without a cursor or windows that can be moved around. It's called a "Command line tool"

If this is too uncomfortable we can skip sraight to installing a desktop system so that you can use a normal window based text editor.

Docker

Sun, 04 Feb 2018 00:00:00 +0000

Docker is a tool that lets people create software packages that can be run on any system that supports Docker and the same processor architecture.

Needs

Website (connected to Internet optional)

Generate

Create a Dockerfile

The Dockerfile picks a base "image" and adds the necessary files needed to run the website. The base image should have the same software that you used to create your website with. After the first website, usually you create a Dockerfile right away that resembles a project that you've created before.

FROM rpi-whatever
WORKDIR /www
ADD index.html index.html
CMD ["python", "-m" ,"SimpleHTTPServer", "9090", "."]

Operate

Build website with docker

docker build -t mysite.com .

Start website with docker

docker run -d --restart always \
--name mysite.com-www \

mysite.com

This is a long command, so it's useful to put it into a script file. Let's call it start.sh.

Script files have two extra parts, there is a top line that tells it which command to use to run (what you normally interact with on the screen is called bash).

#!/bin/bash

[the commands]

And then run

chmod a+x start.sh

Destroy

Stop docker process

docker rm -f mysite.com-www

Desktop

Sun, 04 Feb 2018 00:00:00 +0000

Installing a desktop is a side route and not required for any kind of services, but it's comfortable for people to be able to use a mouse and have a familiar graphical interface to use. It's similar to Mac and Windows, but something different called Linux that is created as free software similar to the methodology used to create this set of tutorials.

Needs

1 raspi
keyboard
mouse

Generate

The desktop system is a software package like any other. It can be installed and uninstalled, is optional to start and stop, and can be configured to start automatically.

sudo apt-get install ____

There are a number of pieces to install to this, beyond the scope of what I hope to accomplish. Others have created a script that we can leverage. It's good practice to study the source code. Here's the full command:

``
startx will run the desktop system

Operate

Destroy

Go to account and then logout, which will return you to the command line (like old school MS dos)
sudo apt-get remove _____
