kubectl helper tools
There are many good tools that extend kubectl functionality or makes working with Kubernetes on the command line a better experience. kubectx and kubens are good examples.

Pinescript working if-(then)-else examples
tl;dr – I wrote some working IF statements that I could copy/paste for myself to Pinescript, as this construct is among the f*cked up ones in this language.

LVM snapshots, destroy or merge?
