## Why the Risks in the Derivatives Market are Often Overblown

Doom pornographers often enjoy posting terrifying tweets of the monstrous Jupiter sized derivatives market. The bubble boys love to post how any day now one of these banks with too much exposure to derivatives will…

## Creating an Adjacency Matrix Using the Dijkstra Algorithm for Graph Convolutional Networks GCNs

Alright so you have a list of geocoordinates (for example maybe street sensors) and you want to create an adjacency matrix to feed into your PyTorch or Tensorflow GCN model such as the A3T-GCN. This…

## Quantitative Easing isn’t Inflationary

The greatest misunderstanding on finance Twitter is central bank lingo. For the past decade and a half tweeps have been yelling that quantitative easing QE is going to cause hyperinflation and the end of the…

## Understanding the Tether Stablecoin Dilemma and the Liquidity Issue

## My Favourite Podcasts From 2022 With Reviews

I was never really a podcast sort of guy and I don’t even know if I ever opened the app on my iPhone before 2022. What did for me was finally turning down the knob…

## Plotting a Macroscopic Fundamental Diagram for Data Scientists in Python for Traffic Flow in Congested Conditions

A Macroscopic Fundamental Diagram, MFD, investigates the flow of traffic through a network of roads that span a spatial dimension. The relationship between the variables speed, flow, and density can be shown in three diagrams…

## Plotting the Optimal Distance for Data Scientists in Python using the K-Nearest Neighbour K-NN Algorithm

This example uses the K-Nearest Neighbour K-NN to connect several points and plotting those as a graph on a Plotly map. This is a quick and simple example that data scientists can use to illustrate a path(s)…

## Plotting the Optimal Route for Data Scientists in Python using the Dijkstra Algorithm

The following example uses OSMnx to generate the optimal path between two geocoordinates and between one and many points and plotting the path(s) on a Plotly map. This is a quick and simple example that…

## Modern Day Parallels to 20th Century Business Plots

We’ve lost interest in democracy and have become enamored with the glamour of technocrats and kleptocrats abetting the rise of modern-day fascism. If you really would like to understand how far right the United States…
