Shortcuts that I overrode for Excel:

Editing a cell is now CMD + Return/Enter/Shift (used to be Option + U or F2)

Setup:

Install Karabiner-Elements
Set everything up properly
Go to your terminal and run cd ~/.config/karabiner/assets/complex_modifications && touch excel.json
Copy and paste everything from the json content below into excel.json
Go to Karabiner-Elements > Complex Modifications > Import Rule then enable the Excel rule thingy

AWS EKS service provides the Kubernetes control plane. Price for EKS Service is $0.20 per hour / cluster.

EKS Use Case Monthly Cost

Three clusters with four worker nodes.

Example database setup of fine-grained role-based access control

For full code example using an ORM and all SQL queries shown, please visit: https://github.com/Andrew-Chen-Wang/role-based-fine-grained-access-control

This is an example implementation of relational database tables for fine-grained access control with custom permissions and roles, similar to AWS IAM roles and policies/permissions.

The example demonstration utilizes Django models as an easier way to interpret. It is also because I ripped it off my current application for others to inspect.

At Lazify, we allow roles to be dynamically created for our enterprise customers. We assume permissions are not allowed to be generated. This is because permissions, in our application, are baked into our backend logic. If dynamic permissions are allowed, prefer the method described in point 1 using a Permission table and an M2M between Permission and your User; just note that the below Python implementation does not demonstrate this.

	I've had to monkeypatch django-ratelimit due to slow development.
	The patch is basically allowing Django Axes with Django ipware
	to grab the IP address rather than taking the IP straight from
	META attribute in the request object.

	You can find an initial implementation here:
	https://github.com/jsocol/django-ratelimit/pull/208

	but the PR lead no where due to just not knowing how

	let spreadsheet = "Today's Save Plates"

	function capitalizeFirstLetter(string) {
	return string.charAt(0).toUpperCase() + string.slice(1);
	}

	function increment_char(c) {
	return c !== 'Z' ? String.fromCharCode(c.charCodeAt(0) + 1) : 'A';
	}
