Data Lake, Data Lab, Data Hub: what's the difference?

In this post we’ll explore the concepts of data lake, data hub and data lab. There are many opinions and interpretations of these concepts, and they are broadly comparable. In fact, many might say they’re synonymous and we’re just splitting hairs. But let’s look again carefully. We can discern some subtle trends in the way people are doing things, and find distinctions in these expressions.

What's new in security for Ubuntu 21.04?

Ubuntu 21.04 is the latest release of Ubuntu and comes at the mid-point between the most recent Long Term Supported (LTS) release of Ubuntu 20.04 LTS and the forthcoming 22.04 LTS release due in April 2022. This provides a good opportunity to take stock of some of the latest security features delivered in this release, on the road to 22.04 LTS. Ubuntu 21.04 brings with it a vast amount of improvements and features across a wide variety of packages.

Introduction to open source private LTE and 5G networks

It’s so easy these days to set-up your own WiFi network. You order a router online, plug it into the electrical socket, define a password and you’re good to go. WiFi is fast, reliable and easy to use. But if you want to cover a wider area or connect hundreds of small devices it quickly becomes inefficient and expensive. Is the only way to go to your local mobile network operator and sign a contract? No! Thanks to open source technology, you can build your own LTE or 5G network.

The State of Robotics - April 2021

Together we have reached the end. Two partners, two allies, two distributions that supported millions of innovators have reached their end-of-life (EOL). April will be remembered as the month where ROS Kinetic and Ubuntu Xenial reached EOL. ROS Kinetic is one of the most used, widely deployed and extensively contributed ROS distributions (1st with 1233 repos in ros/rosdistro). Released in 2016, it supported newer related components, notably Gazebo 7 and OpenCV 3, and this month has reached its end.

KubeCon Operator Day keynote with Mark Shuttleworth

Operators, Models, Kubernetes, Hybrid Clouds, massive scale and bootstrapping quickly - Kubernetes is taking the the world by storm. So what's next? Mark Shuttleworth (one time astronaut, founder of Canonical, the company behind Ubuntu) talks with David Booth (VP Cloud Native Applications at Canonical) about the past and lays down a vision for the future. Miro board Juju website The Kubernetes and Cloud Native operations survey.

Simplifying MLOps with model-driven operators

In early markets such as MLOps, solutions to parts of a large problem arise from multiple open source communities, startups and industry leaders. For the consumer, this entails one problem - integrating pieces of a software puzzle in a maintainable way. Model-driven operators promise a solution by connecting the ops of a single application with declarative integration in a standard that empowers providers.

Highly available Kubernetes in IoT: MicroK8s on RaspberryPi

Learn how to set up a Pi-Hole instance with a single command and a cluster of Raspberry Pis on MicroK8s. High availability, load balancing and Kubernetes configuration included. The Raspberry Pi 4 brings the graphics, RAM and connectivity needed for a Linux workstation, so why not use a cluster to set up your own Pi-Hole, the open source network-level ad blocker that acts as a DNS sinkhole or DHCP server.

Secure container orchestration at the edge

The cloud-native way of building software allows for consistency across developer environments and massive scalability of application deployments. Both these attributes are useful for edge, but create new challenges related to security and resilience. Watch this demo to see how Canonical’s modular technology stack addresses these challenges by using well-known cloud primitives.
