Making multiple MySQL versions work with Homebrew was tricky to say the least. Fortunately there are 2 new easy ways that I learned of to achieve this.

DBngin app

As @4unkur and @henrytirla commented below, there is this extremely easy to use app called DBngin, which lets you setup multiple databases (not only MySQL) simultaneously using different ports:

Running Sway on Void Linux (without SystemD)

elogind is the part of SystemD logind that can run as standalone. So we need it to run Sway without SystemD. To do that we need to build wlroots with elogind option. Then we can install and use Sway as normal from the current repo. There are other ways to achieve this without elogind here. But I tried with the elogind option and I was successful.

UPDATE: I tried again on a fresh install. The elogind option is set by default on the repo version. So you can skip the xbps-src command below and continue. wlroots should install as a dependency of sway if you follow the later commands.

git clone git://github.com/void-linux/void-packages.git
cd void-packages
./xbps-src binary-bootstrap

Kubernetes v1.16 API deprecation testing

Examples of how to test the impact of the v1.16 API deprecations and ways to debug early!

If this is the first time you're hearing of these deprecations STOP and read this blog post (thanks @vllry!).

Common misunderstandings

The exact apiVersion: value that I use in my manifest is stored on disk (etcd).

Fetch details of an existing RKE cluster template:

data "rancher2_cluster_template" "hardened" {
    name = "hardened-template"
}

or create a new RKE cluster template:

	# export the task def
	family='TaskDefName'
	$ aws ecs describe-task-definition --task-definition $family \
	--query "taskDefinition.{family:family, taskRoleArn:taskRoleArn, executionRoleArn:executionRoleArn, networkMode:networkMode, containerDefinitions:containerDefinitions, volumes:volumes, placementConstraints:placementConstraints, requiresCompatibilities:requiresCompatibilities, cpu:cpu, memory:memory, tags:tags, pidMode:pidMode, ipcMode:ipcMode, proxyConfiguration:proxyConfiguration}" \| jq 'del(.[] \| nulls)' > taskDef.json

	# import the task def into newFamily task family
	$ aws ecs register-task-definition --cli-input-json file://taskDef.json --family newFamily

	# one-liner
	aws ecs describe-task-definition --task-definition $family \
