This page is a curated collection of Jupyter/IPython notebooks that are notable for some reason. Feel free to add new content here, but please try to only include links to notebooks that include interesting visual or technical content; this should not simply be a dump of a Google search on every ipynb file out there.

Important contribution instructions: If you add new content, please ensure that for any notebook you link to, the link is to the rendered version using nbviewer, rather than the raw file. Simply paste the notebook URL in the nbviewer box and copy the resulting URL of the rendered version. This will make it much easier for visitors to be able to immediately access the new content.

Note that Matt Davis has conveniently written a set of bookmarklets and extensions to make it a one-click affair to load a Notebook URL into your browser of choice, directly opening into nbviewer.

HP Smart Storage Admin CLI (`ssacli`) installation and usage on Proxmox PVE (6.x)

Why use HP Smart Storage Admin CLI?

You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS. That means no host downtime when managing your storage.

CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.

ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.

Installation

Method 1: NFS server on LXC container

Create a priviledged LXC container with:

mount=nfs,nesting=1

apt update

apt install nfs-kernel-server

This (and related gists) captures how i created my docker swarm architecture. This is intended mostly for my own notes incase i need to re-creeate anything later! As such expect some typos and possibly even an error...

Installation Step-by-Step

Each major task has its own gist, this is to help with maitainability long term.

Deploying Traefik using forward proxy mode with Authentik

This is an example guide how to deploy Authentik with Traefik in forward auth proxy mode - that means that any application behind the proxy will be automatically authenticated by Traefik. This allows better reuse of code and completely moves user management to Traefik & Authentik.

In this guide we use custom DNS to make the requests nicer and to show that it works with DNS. So step #1 is to put following records to your /etc/hosts (for example by sudo nano /etc/hosts and adding these values)

Mastodon Docker Setup

In this guide we will only focus on using the prebuilt images from Docker Hub.

Prerequisites: You have Git, Docker, Docker compose and Nginx pre-installed.
