A secure and private open source alternative to Alexa
I grew up in rural towns all over Ontario, Canada. We weren't particularly well off, although, as a kid in the middle of nowhere, I wasn't really aware of our socioeconomic status. What I was aware of was this beige box called a computer that sat in my dad's office. Dad worked for the bank, and for his job, it was essential for him to have a computer.

Provision Kubernetes NFS clients on a Raspberry Pi homelab
Ephemeral containers are useful, but sometimes data needs to persist between containers or be shared among multiple containers. The solution is mounting external volumes inside the containers, and this is done in Kubernetes with persistent volumes. In large, public cloud deployments, Kubernetes has integrations with the cloud providers' block-storage backends, allowing developers to create claims for volumes to use with their deployments, and Kubernetes works with the cloud provider to create a volume and mount it in the developers' pods.
