Keybase proof

I hereby claim:

• I am msmyers on github.
• I am msmyers (https://keybase.io/msmyers) on keybase.
• I have a public key ASCKtjsOcPrM7iRvq9ROBPnezPWsoBWUJNzP3KK808HuEAo

To claim this, I am signing this object:

# Assumptions: easyrsa3 available in current dir, and functional openssl.
# This basic example puts the "evoeco_ca" and "children_ca" PKI dirs on the same system.
# A real-world setup would use different systems and transport the public components.

Installing cloud-init on a fresh Raspbian Lite image

This is a work in Progress!

Purpose

This mainly demonstrates my goal of preparing a Raspberry Pi to be provisioned prior to its first boot. To do this I have chosen to use the same cloud-init that is the standard for provisioning servers at Amazon EC2, Microsoft Azure, OpenStack, etc.

I found this to be quite challenging because there is little information available for using cloud-init without a cloud. So, this project also servers as a demonstration for anyone on any version of Linux who may want to install from source, and/or use without a cloud. If you fall into that later group, you probably just want to read the code. It's bash so everything I do, you could also do at the command line. (Even the for loop.)

Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

1. List the topics to which the group is subscribed

kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe

Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

2. Reset the consumer offset for a topic (preview)

By default, binaries installed by gem will be placed into:
  /usr/local/lib/ruby/gems/3.1.0/bin

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have ruby first in your PATH, run:

msmyers

#!/bin/sh

# This script installs the Nix package manager on your system by
# downloading a binary distribution and running its installer script
# (which in turn creates and populates /nix).

{ # Prevent execution if this script was only partially downloaded
oops() {
    echo "$0:" "$@" >&2
    exit 1
