Null Std nullstd

This example demonstrates how to take the size of objects into account when selecting objects efficiently with a quadtree. Selected objects are shown in red, visited but not selected objects are shown in yellow. The efficiency depends on the biggest width and biggest height among all object. It is assumed that all objects are rectangle-shaped.

Example series:

Quadtree 1
Quadtree 2
Quadtree 3

Based on Mike Bostock's quadtree example.

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

Docker with SSL and an nginx reverse proxy

Running your ASP.NET Core (or other) application in Docker using SSL should not be an overwhelming task. These steps should do the trick.

Run the following steps from a Linux terminal (I used WSL or WSL2 on Windows from the Windows Terminal).

1. Create a `conf` file with information about the cert you'll be creating

It should look something like the content below; call it my-site.conf or something like that.

Ingress MetalLB

Out of the box, the MicroK8s distribution of ingress-nginx installed as the MicroK8s addon ingress binds to ports 80+443 on the node's IP address using a hostPort, as we can see here:

microk8s kubectl -n ingress describe daemonset.apps/nginx-ingress-microk8s-controller
Name:           nginx-ingress-microk8s-controller
Selector:       name=nginx-ingress-microk8s

	#!/usr/bin/env python3.5
	import socket
	import asyncio
	from struct import pack, unpack


	class Client(asyncio.Protocol):
	def connection_made(self, transport):
	self.transport = transport
	self.server_transport = None
