Predicting Diabetes with Machine Learning – a brief introduction to Tensorflow: AI for Dummies #1

Everybody uses AI for almost everything these days. From helping shaping ideas to the recommendation systems that tells us which movie to watch next, it’s almost omnipresent. But for many of us (myself included), what happens “under the hood” remains a complete mystery, seeming, at times, almost magical.

This post is the first in the AI for Dummies series, where we’ll try to demystify AI, by learning what it is and how it works, starting from simple use cases and concepts and evolving into more complex and real-world scenarios. This post also serves as an introduction to a few key tools, such as Tensorflow and Keras, as well as a brief introduction to important concepts in this domain.

Configure Spotify’s backstage with Keycloak OiDC as Auth Provider

Spotify’s backstage is a widely used developer portal framework. When properly configured, it is very powerful and integrates with dozens of other tools that are used daily by developers, managers and devops teams.

One of the first aspects to consider when setting up backstage is the user access and authentication. Although Backstage provides a few out-of-the-box identity provider integrations, Keycloak is not one of them, and the process to configure it can be a bit daunting, especially if one is new to Backstage and how it is structure.

This article aims to provide a step-by-step guide on how to create a Keycloak OiDC client and how to configure Backstage to use it.

Setting up a secure Mosquitto MQTT Broker with SSL/TLS and User Access Control– MQTT series #2

Hi and welcome back to the MQTT series, where we’ll go from the protocol basics, to real-world implementations of different use cases, using different brokers and clients. In this article we’ll see how to setup secure a Mosquitto MQTT Broker with TLS and Access Control.

In the previous article we’ve covered the protocol basics, saw how it compares to HTTP and why it is so relevant for IoT.

Today we’ll explore one of most used brokers: Eclispe Mosquitto. We’ll discuss the role of a broker in a MQTT-based architecture and while covering some advantages and disadvantages of Mosquitto, which should help you understand if this is the suitable broker for your use case.

MQTT – The defacto IoT protocol – MQTT series #1

Welcome to the first of a series of MQTT-related articles. In this series, we’ll cover different aspects of the MQTT protocol, from its low-level protocol specification to the deployment of an MQTT broker, from simple to more advanced scenarios.

If you’re starting with MQTT or want to learn more about this protocol, you have come to the right place.

In this first article, we’ll cover the protocol basics and why it is so relevant for IoT communication.
