So it's an article about hardware, screens, and typical linux command line tools? What is the whole point he is trying to make that is not covered in 1000s other articleS?
As for why it's notable and on the front page, if you don't know who Alex Ellis is, I strongly suggest you take a closer look at the OpenFaaS org on GitHub, if you're at all into K8s or want to do serverless stuff on K8s. Last week I had heard of this guy and thought I mostly knew why he was notable, but this weekend I started to try working with OpenFaaS, and found no less than 5 or more important projects under his name while traveling down the rabbit hole of "what's the best way for me to run this as a developer" – if my experience is not unique, then that answers it for me, why HN apparently cares what his setup is like in particular.
Check out K3sup and inlets-operator, for example. The most surprising problem I solved on his dime this weekend was "how do I use cert-manager to get certificates for my Kubernetes ingresses, when the K8s cluster is private and LetsEncrypt can't reach it?" – I wasn't even hoping to solve this, but it just works out of the box, with a handful of apps provided through "k3sup app install" (including cert-manager, of course), your ingresses can get a public IP for long enough to perform the HTTP challenge, and your private cluster can get TLS certs handled automatically for a couple pennies, without any awkward certificate secrets hand-off process (where an admin carries the TLS certs from an internet-facing cluster over to the private cluster, for example, as I've heard of others doing to bootstrap their private clusters.)
