Let’s have a look at two popular ways of opening remote shells: the good ol’ ssh and its modern counterpart, kubectl exec. Below, I will only look at the “kubectl exec” subcommand and its friends. kubectl itself is a swiss-army knife for all things Kubernetes. Comparing all of it to ssh is like comparing systemd to BSD init. Also, I will use “SSH” to mean “OpenSSH”, which is the de-facto standard for SSH protocol implementation.

Did you know that in the United States, the Social Security Number was never intended to become the defacto method for physical identification? On its surface, this may come as a shock given how ubiquitously SSNs are used for this exact reason, but looking beneath the surface, we find that SSNs are terrible forms of identification. Ignoring the security concerns of a nine digit numeric code, an SSN is not for universal identification.

Just like how computers use trusted third parties and chains of trust to connect with one another, organizations use (admittedly much slower and more human powered) authoritative standards organizations (AICPA) and certified audit firms to create a trust system between organizations.

Designing software is tough. Whether you’re a designer, a product manager, or an engineer, we all play a major role in what the end user gets their hands on. Perhaps one of the most critical pieces on the journey to making great software is the relationship between designers and developers. When software is done right, it’s easy, intuitive, and a joy to use. This is no accident - it’s very intentional and it often takes countless iterations to get products to look and feel great.
