You can demostrate how kubernetes stores everything in etcd (v3):

One-liner

You can exec etcdctl rigth in the etc pod:

kubectl exec -it \
  -n kube-system etcd-minikube \
  -- sh -c 'ETCDCTL_CACERT=/var/lib/localkube/certs/etcd/ca.crt \
 ETCDCTL_CERT=/var/lib/localkube/certs/etcd/peer.crt \

DOM Performance

• How the browser renders the document
  • Receives the data (bytes) from the server.
  • Parses and converts into tokens (<, TagName, Attribute, AttributeValue, >).
  • Turns tokens into nodes.
  • Turns nodes into the DOM tree.
• Builds CSSOM tree from the css rules.

If you use Storybook with Next.js and have components using next/link you'll have to mock next/router the same you would for testing with Jest or others. Simply create a file with the mock router as shown below and import it in your Storybook config.

This is based on some information from an issue on Next.js:

Building a Nix Package (The C&C++ Version)

Nix can be used to build any kind of package. But here I'm just going to focus on the simple C&C++ case.

Firstly we have to know that the final built packages will located inside /nix/store. Which is globally readable directory of all build inputs and build outputs of the Nix system. The emphasis is on readable, not writable, that is /nix/store is meant to be modified by the user or programs except for the Nix system utilities. This centralises the management of packages, and keeps our packages and package configuration consistent.

So what exactly are we trying to build. Our goal is to build a directory that will be located in /nix/store/*-package-version/, where * is the hash of the package. Preferably a version is also available, but some C&C++ packages don't have versions, so in that case, there's only /nix/store/*-package/.

What will be inside this directory? It follows the GNU Coding Standards descri
