Installing Python 3.6 on Raspbian

As of January 2018, Raspbian does not yet include the latest Python release, Python 3.6. This means we will have to build it ourselves, and here is how to do it. There is also an ansible role attached that automates it all for you.

1. Install the required build-tools (some might already be installed on your system).

How to passthrough SATA drives directly on VMWare EXSI 6.5 as RDMs

There aren't many tutorials about this, the only tutorials I've found were about passing through entire PCIe cards to VMs, or refered to old ESXI versions (below 6.5) that used a more comprehensive desktop client instead of the web app. In v6.5, the web app was introduced and the desktop client was deprecated. You used to be able to setup RDMs in the desktop client, but with the introduction of the web console, this is no longer the case. This tutorial shows you how to pass SATA HDDs to the virtual machine on VMWare ESXI 6.5. This tutorial is partially based on VMWare's own KB and the now deprecated Forza IT blog post.

A word about VMWare ESXI 6.7

There is now an option while editing your VM's settings to add a New raw disk when you click `Add ha

Bootstrap sidero cluster

Below is some basic notes on how i setup and tested sidero on a local laptop

First steps

• Read the docs https://www.sidero.dev/docs/v0.4/ and https://www.talos.dev/docs/v0.14/ and understand a bit on the concepts.
• Grab the binaries - https://www.sidero.dev/docs/v0.4/getting-started/prereq-cli-tools/. Install talosctl, clusterctl. You probs have kubectl. Clusterctl is awesome for creatin ga local docker cluster for instant testing, and talosctl is what you use to talk to talos via api (talosctl -n <nodeip> dmesg | reboot | logs)

Don't grab your clusterctl from arch AUR, its not the right version!

• Figure out your desired baremetal structure. From your git it looks like you have a pi-master - welcome to level 1000. Im running one just fine, but it does increase the complexity/bullshittery. Probs grab some tissues or stand up amd64 nodes first.
• Now to setup dhcp for dual booting. If you do amd64 its not so bad as its one config, but with pi you need to config it to
