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 tutorial uses OSMnx to measure the distance of optimal paths between each of the geocoordinates…

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 US Dollar. None of these doomsday predictions have materialized. …

You might not like the new owner and are worried about you data. Perhaps you’re a journalist who quickly needs to scrub tweets. Maybe you just want delete your childish embarrassing tweets from when you were young. You want to start over. Turns out many services only delete the last…

After the recent FTX collapse I want to return attention to what really is the underlying problem with the entire crypto ecosystem, namely the lack of real liquidity. This was brought on by the introduction of stablecoins in the previous bull market starting 2014, an almost monopoly ended up going…

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 a bit on the amount of music I consumed throughout the day making more time…

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 and together make up the MFD. The diagram can then be used to identify the…

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 graph for their professional or academic papers. A brief file structure overview of the…

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 data scientists can use to illustrate a path(s) for their professional or academic papers. A…

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 has shifted then look no further than building schools and roads which are now largely…
