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.
Every week I include a six-question interview with an inspiring data person. This week, I speak with Florent Daudens of Le Devoir, a French-language Canadian newspaper which is widely respected for its brilliant approach to interactive data-driven journalism.
There’s a pretty good job opening going at The Guardian, where Ashley Kirk is looking for a Graphics Editor to lead their daily news production team. You can read the job description and apply here
A final shout out to DataJournalism.com’s State of Data Journalism 2021 survey, which many of you might be interested in contributing to: What is the most difficult part of being a data journalist? What tools are currently being used, and how are they perceived by data journalists who use them? How much does the role vary across the globe? Let us know in the survey! The survey offers some very special rewards, including the chance to win a trip to the International Journalism Festival 2022 in Perugia, as well as Amazon Coupons and Digital Goodies.
‘till next week,

This chart on the ratio of acute metrics to COVID cases is one of the best I’ve seen in months, but the whole thread contains some very useful graphics to digest.
The Economist captures visually what Twitter seems to be admitting about its algorithms.
“In the map below, you can see 373 stories of violence towards the queer community in Berlin, collected over the last seven years. The data comes from the Berlin Register, a website that tracks discriminatory incidents and right-wing extremists.“
This is by Rebecca Mary Peake, a junior software developer at Datawrapper.
The United Nations’ OCHA Centre for Humanitarian Data has published this incredibly visual story about “a Chadian girl’s daily journey to collect water [which] illustrates how the climate crisis is affecting her community”, with links to the data.
Parsehub is a web scraper SaaS with a relatively generous free tier.
“A novel dataset consisting of very high resolution multi-spectral satellite images of landfills from Germany, Hungary, Serbia, India and Brazil”, with this blog post describing which steps and datasets the author used to create it.
The Economist’s data team explains in their Off The Charts newsletter the approach they took to visualising the 12-year journey of Lucy, a space probe that visited eight different asteroids.
Useful visual summary by The Guardian, using data from Climate Action Tracker and the World Bank.
“With interpretability becoming an increasingly important requirement for machine learning projects, there’s a growing need for the complex outputs of techniques such as SHAP to be communicated to non-technical stakeholders.“
Data scientist Aidan Cooper explains SHAP in practical terms and discusses what it can be used for.
“Over the years, more women have entered the workforce while the percentage of men has gone down slightly. The chart below shows the shifts since 1960.“
As per usual approach, Nathan at FlowingData also shares links to the data and methodology.
The food timeline is a website that was started in 1999. Its last update dates back to 2021, but I suppose that its UI never changed since the beginning… Jokes aside, its contents are way more interesting.
quantum of sollazzo is also supported by ProofRed’s excellent proofreading service. If you need high-quality copy editing or proofreading, head to http://proofred.co.uk. Oh, they also make really good explainer videos.
