TIL the POD in Podman is the same idea as Pods in Kubernetes. Pods are collections of containers that share resources (i.e. volumes, networks, etc.). Create a pod with the podman pod create --name [pod-name] command. You will need to expose ports and setup other resources with the pod create command.

podman pod create --name my-new-pod --infra --publish 8080:80 --network bridge 

Add a container to a pod with the --pod [pod-name] flag in your run command:

podman run -d --pod my-new-pod --name my-nginx docker.io/library/nginx

Load in a browser and see the default nginx page from your pod!

TIL about the special-use *.home.arpa tld. The .home.arpa tld is reserved for “non-unique residential home networks”. If you use Adguard Home, Pi-Hole, or any other DNS server you can freely use .home.arpa for all your local assets (printers, self-hosted server, etc.)!

TIL an easy way to remember if you want a slash or not when you run rsync. A trailing slash will copy the contents of the directory while just the directory name will copy the directory itself. For example

# copies everything in dir into new-dir
rsync -r dir/ new-dir

# copies dir into new-dir
rsync -r dir new-dir

TIL about Python List Comprehensions. I came across code that looked like this in a codebase.

 baz = [foo.bar for foo in foos] 

I could see what was happening (baz is now a list of bar for each object in foos). I didn’t know this was called list comprehension but now I understand the data structure.

List comprehensions are useful for lots of things when you want to create lists from other objects (docs source).

TIL that you can output all the data in “the dot” from a Hugo template using jsonify

<pre>{{ . | jsonify (dict "indent" "  ") }}</pre>

Here is the output of the .Params value for this post

<pre>{{ .Params | jsonify (dict "indent" "  ") }}</pre>

TIL about ncal (most Linux distros) or CAL (on MacOS). I have used cal for quite a while which is a convenient calendar tool in the terminal. However, I hit CAPS LOCK on accident and ran CAL instead of cal, to my surprise it output
