Simple steps for getting Kubeflow off the ground on your Mac (hint: it’s not ‘helm install…’)

MicroK8s

MicroK8s is a fully-compliant mini Kubernetes implementation. Thanks to its tiny footprint, it is perfectly suited for local installation. We’ll install it with brew:

➜ brew install ubuntu/microk8s/microk8s

Once it’s installed on your machine, we can provision a local cluster this way:

➜ microk8s install --cpu 2 --mem 8

The additional --cpu and --mem parameters increase the CPU count and memory allocation, which will be helpful later on when we start experimenting with Kubeflow. If everything goes well, you should see this output:

In this article, we will look at how testing differs for Event-Driven systems when compared to traditional point-to-point architecture and we’ll propose an alternative approach for implementing a robust testing strategy for these systems.

Event-Driven architecture refresher

First, let’s do a short review of what an Event-Driven architecture looks like, compared to a traditional point-to-point, synchronous system. Let’s start with the traditional design. Below is an example of an order processing system, which handles payments, shipments, inventory management, and email notifications.

Do you ever find yourself in a need of connecting a monitor, keyboard, and a mouse to your RaspberryPi, just so that you can get its current IP address and then SSH into it from your computer? If so, this short tutorial might help you remove this choir. We will configure an LCD display to show the current IP address of the RaspberryPi at boot time.

Prerequisites

Here are the components we will use:

• Raspberry Pi 4 — you can use any earlier version, as well
• Extension Board — I used a similar to this one
• LCD1602 with an I2C interface…

I recently discovered a new-found passion for DIY projects around IoT devices and set out to build an AI-enabled robot — Nvidia’s JetBot AI. In this first part of the series, I will share my experiences from building the JetBot. In Part 2, I will cover the software side of the robot.

JetBot is powered by Nvidia’s Jetson Nano — a Single Board Computer (SBC), similar to a RaspberryPi, however with one important advantage over it — it sports a powerful 128-core GPU onboard. …

TL;DR

There’s a hard message to be delivered and you’ve likely heard it already — it’ll be a long time before things return to normal. Health experts and epidemiologists agree on this on all accounts, some saying this crisis will permanently change the way we work. To survive, businesses need to adjust to the new reality, rather than close down to wait out the storm.

This post is not a philosophical debate about the superiority of Agile over Waterfall. …

On a recent project, I was working with a team making their first stride into the cloud. The team was maintaining a small portfolio of custom-built applications written in Ruby on Rails and JavaScript (MEAN stack), which were deployed on a local data center and intended to migrate their software into AWS. As the main pain points for the team were manual application updates and rolling out infrastructure changes, the project, from the get-go, was focused on automation. …

A while back I was working for a mid-size client who used AWS as their infrastructure provider. For a long time, there had been little governance over the AWS account, with development teams having full access to the account functions and often provisioning their applications manually. As the cumulative ecosystem of the organization grew to around 300 EC2 instances, manual provisioning was being gradually phased out across teams in favor of automation, thanks to services like CloudFormation, Elastic Beanstalk, and Ansible, however originally set privileges remained still in place.

On one occasion, a set of AWS access keys accidentally leaked…
