The data newsletter by @puntofisso.
Hello, regular readers and welcome new ones :) This is Quantum of Sollazzo, the newsletter about all things data. I am Giuseppe Sollazzo, or @puntofisso. I've been sending this newsletter since 2012 to be a summary of all the articles with or about data that captured my attention over the previous week. The newsletter is and will always (well, for as long as I can keep going!) be free, but you're welcome to become a friend via the links below.
The most clicked link last issue was the NYC Noise Digital Twin.
It's AMA o'clock!

🛠️📖 Tools & Tutorials
Wardley Mapping templates

The Data Visualisation Catalogue
"The Data Visualisation Catalogue is a project developed by Severino Ribecca to create a (non-code-based) library of different information visualisation types. The website serves as a learning and inspiration resource for those working with data visualisation."
Flourish: custom grids of charts
I like this – Flourish has released a way to build custom grids of charts, which can be arranged in a multitude of ways. The one below is geographically arranged by US State. It needs a (free) account.
Building a Single-Page App with htmx
This could be a good starter: "It’s a simple proof of concept todo list. Once the page is loaded, there is no additional communication with a server. Everything happens locally on the client.
How does that work, given that htmx is focused on managing hypermedia exchanges over the network?
With one simple trick: the “server-side” code runs in a service worker."
I haven't managed to use htmx yet, but it looks like it's got plenty of use cases where it would speed up development.
Circle clusters and heatmaps for dense point data in R
This is "a tutorial on some features in my new R package, mapgl, for visualizing clusters of dense point data without showing a bunch of “dots on a map”".
Geocoding CSV files from the command line

🤯 Data thinking

Hurricane Wind Speeds: Understanding the Effect of Model Grids
Cameron Beccario, creator of earth.nullschool.net: "Most of the data you find on earth.nullschool.net and other weather sites/apps come from numerical weather models. These are computer programs that simulate the physical processes of Earth as realistically as possible. They can be very expensive computationally and often require supercomputers to reach the level of detail that is useful for accurate weather forecasting."
A good explanation follows.
🤖 AI
Do AI companies work?
I'm not a market expert but there's something in here that makes me think: "The market needs to be irrational for you to stay solvent."
Google AI vs "vs"
This is hilarious...
