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.
‘till next week,
Giuseppe @puntofisso

Visualizing Your Personal Gender Pay Gap: How Does Your Salary Compare?
“Every year the Data Visualization Society (DVS) conducts a huge survey called the State of the Industry—collecting a rich array of data that paints a picture of the data visualization industry today: who is in it, what exactly do they do, and how do they do it?“
Elezioni 2022, ecco la mappa dei collegi elettorali di Camera e Senato
A general election in Italy will happen in a few weeks. Last week’s Six Questions guest Riccardo Saporiti has written about it, using the recently released official maps of electoral boundaries. In Italian and automatically translated into English. (via Luca Tremolada)
Real-Time Statistics on Europe’s Gas Supplies
“Gas supplies are flowing to Germany from Russia again after maintenance on the Nord Stream 1 pipeline, but how well filled are the country’s gas storage facilities? Is the country successfully reducing its reliance on Moscow? You can follow the data with our live tracker.“
By German magazine Der Spiegel.
Fear of Rampant Crime Is Derailing New York City’s Recovery
“Violent incidents are up since the pandemic began — and New Yorkers are nervous. But widespread anxiety obscures the fact that crime is still at decades-long lows.“
Just look at the chart below and some of the other stats :(
The staggering scope of U.S. gun deaths goes far beyond mass shootings
“There is not one clear answer as to what is driving the rise in bloodshed, experts said, but possible factors include the stress of the coronavirus pandemic, fraying ties between the police and the public, mounting anger, worsening mental strain and the sheer number of guns in America.“
A look at some data about gun sales and deaths.
Myanmar Conflict Map
“The Myanmar Conflict Map is a platform for tracking, visualising, and analysing reports of violence in Myanmar.“
By the International Institute for Strategic Studies.
Tools & Tutorials
Tutorial – Where are the nearest OBGYN emergency rooms and maternity wards?
Another great tutorial by AllThatGeo:
“in this month’s tutorial, I’m sharing how I used Web AppBuilder to create an app to find the nearest emergency room to any given point. Here’s the high-level workflow I followed:
Choose the tool: ArcGIS Web AppBuilder.
Prepare the data: Extract the data from the source and add it to ArcGIS Online.
Create a visualisation: Configure Theme, Map, Attribute and two Widgets: Near me (including routing service) and About.
Share your work: Preview the app in different screen sizes and publish it for public access.”

The Bayesian Bootstrap
“In causal inference we do not want just to compute treatment effect, we also want to do inference (duh!). In some cases, it’s very easy to compute the asymptotic difference of an estimator, thanks to the central limit theorem. This is the case of computing the average treatment effect in AB tests or randomized controlled trials, for example. However, in other settings, inference is more complicated. […]
The bootstrap is the answer! It is a very powerful procedure to compute the distribution of an estimator, without needing any knowledge of the data generating process.[…]
Can we do better? The answer is yes! The Bayesian Bootstrap is a powerful procedure that in a lot of setting performs better than the bootstrap.“
An indepth explanation of the Knuth-Morris-Pratt algorithm
An article that helps you understand the Knuth-Morris-Pratt algorithm with animations. KMP is used to perform substring match efficiently.
wandb
“A tool for visualizing and tracking your machine learning experiments.“
“Use W&B to build better models faster. Track and visualize all the pieces of your machine learning pipeline, from datasets to production models.“
Open Source Tools for Computational Biology
“The movement towards open source tools and knowledge for building biotech is important for the next wave of biotech innovation. We rounded up free open source software that founders, computational biologists, and data scientists are using that could help you get started on building products.“

Data thinking
Cadastre in Wartime
“Despite the current conflict, the topographic and cadastral land-register services of the Ukrainian StateGeoCadastre are still operational, certainly in the regions where the country is not under attack. Restricted public access to information is the main difference between the cadastre during wartime and the cadastre in peacetime, besides of course the concerns about staff and systems. Major projects, such as facilitating the sale of state-owned land, have been put on hold.“
Who Is Collecting Data from Your Car?
“A firehose of sensitive data from your vehicle is flowing to a group of companies you’ve probably never heard of.“
Building Modern Data Teams
“The modern data stack left behind building high performing teams. We’re here to change that. Curated with love by Emilie Schario and Amplify Partners.“
A good collection of resources.

How far can you go by train in 5h?
“This map shows you how far you can travel from each station in Europe in less than 5 hours.“
(h/t Durand D’souza)
Inflation for Americans at each age
“Households under age 40 spend more of their budgets on items with the fastest-rising prices.“
An interesting look at how inflation affects different groups in different ways. There is also a more in-depth explanation on the Washington Post’s How To Read This Chart newsletter.
Google measures when our phones are at ‘places of work’
A nice dataviz Twitter thread and a YouTube video walkthrough based on Google’s Community Mobility Reports.
