Taints, tolerations and node affinity : the e-magnetism of Kubernetes Nodes in the Kube Scheduler

We can think of Node Affinity as analagous analogus to magnetic attraction;

We can think of Node Taints as the complement of that (magnetic repulsion);

We can think of the determinant of a Node's eventual location as being "up to the Kube scheduler.

That's why we'll often have an effect of NoSchedule for nodes we'll want an exception of sorts for.

• See Scheduling/Eviction: Taints and Tolerations.

Making local dev servers w Webpack 4

To use an environment variable in webpack, set module.exports to a function which returns the config object.

Only a function can take in env and argv as args, and you'll need those.

Then use defineWebpackPlugin to set environment variables.

Remember that Webpack 4 is "no config"; just set mode when you startup webpack dev-versus-prod in your package.json.

WIP. This is a tutorial I'm writing which is in progress :) - Amanda

Intro to binary (and some computer architecture)

Intended audience(s) include:

• Very early career engineers who don't have a 'math background' (yet!)
• Junior developers and interns who want to "understand" rather than just "complete tutorials"
• Web developers who didn't take CS courses, but still want to understand "how things work" "under the hood"
