I’ve been playing a bit with Elementary OS… it is a nice, simple Linux distro based on Ubuntu. Which means that you you can follow the instructions for Ubuntu whenever you need to install any software in Elementary OS. That said, some installation instructions require specifying the Ubuntu codename, to be able to retrieve the right binary from internet, e.g. Installing Docker Engine. A command commonly used to retrieve the codename of your distro is lsb_release -cs.

I had a very large PDF document (18.9MB), which contained 24 large images, and I needed the file to be less than 5MB as I need to upload it on a website where the maximum file size is 5MB. Using Preview on Mac, it is possible to Export a file and select the format as PDF and Quartz filter: Reduced file size. The problem with this approach is that the image quality suffers greatly and the images in the PDF might end up not being that readable. From within Preview, it is not possible to modify the settings used by the Quartz filter. Here is where the ColorSync utility comes to the rescue :-).

There are times when we update an image used in a deployment and we want our k8s deployment to use the latest image. We can achieve this in two ways, doing a rolling restart of the deployment or by specifying the deployment to run an image with a specific tag. Below the imperative commands that allow us to achieve this:

To install and run minikube in Fedora, we first need to install a Hypervisor. In the example below, I will be installing KVM by installing the virtualisation options available in Fedora (https://docs.fedoraproject.org/en-US/quick-docs/getting-started-with-virtualization/). Note: It is also possible to just install KVM - https://computingforgeeks.com/how-to-install-kvm-on-fedora/.
