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 week was Reuters Graphics' look at the impact on heat of different types of surfaces.
'till next week,
The Economist's Graphic Detail: "The extent of newly exposed ocean is the size of Argentina".

Impressive analysis and data visualization. Article on the Financial Times, and, on this Twitter thread, John Burn-Murdoch's salient points.
Carbon Brief: "Human-ignited fires play a decisive role in shaping the Amazon’s future, potentially locking more than three-quarters of the rainforest into a “treeless state”, a new study finds."
Tweet by Max Roser.

Think Markdown for diagrams, getting something akin to ASCII art as a result.
Useful article on Bellingcat – I wasn't aware of PeakVisor!
"A short, shaky video and a single photograph show mourners standing on a mountainside as a row of bodies lie shrouded, about to be buried. Both images appear to be taken from close viewpoints and at nearly the same time — 17:53 UTC on May 28, 2022. But where exactly were they taken?"
"Welcome to the g9 gallery! Drag all the graphics!"
g9 is a library to draw shapes based on data.
"A collection of pure bash alternatives to external processes."
Mapbox's Eric Fischer writes: "Here are some of the lessons I learned in the process about making dot maps look good on the web", at a huge scale.
"Jupyter AI brings generative artificial intelligence to Jupyter notebooks, giving users the power to explain and generate code, fix errors, summarize content, ask questions about their local files, and generate entire notebooks from a natural language prompt."
This blog post offers a look at Jupyter AI, an extension for the popular notebook framework.
Randy Yu: "If you’ve ever run any query that involved joining one or more tables together and counting things, you’ve probably come across situations where you had unintentionally introduced a bug and rows that you thought were singletons became multiple rows with mostly duplicated data."
Don't use DISTINCT to de-duplicate your queries. Write them well in the first place.
"Many of the tags like \<html> don’t make sense to include in the text of a blog post, but if you’re viewing this post on patrickweaver.net, then every one of the elements is used somewhere on this page."
Finance Toolkit is "an open-source toolkit in which all relevant financial ratios (50+), indicators and performance measurements are written down in the most simplistic way allowing for complete transparency of the calculation method."
Cartographer Daniel Huffman explains the thinking behind a map he designed: "This time around, the piece is for a small homeowners association, as requested by one of the residents, who is also my brother. He had originally annotated some satellite imagery back in 2009 and shared printouts with others in the community. As I had learned some cartography in the last 14 years, he asked if I’d be willing to help him re-make his older work."

"Based on hundreds of graph examples, this gallery guides you through the basic concepts of data visualization with React and D3.js. It also provides ready-to-use templates to get started quicker."
"The Straits Times’ digital graphics team and photo desk teamed up to programmatically extract Singapore’s hues from thousands of photos."
"Visualize climate change data with a 3D globe."
"Hi 👋 I’m Luc, engineer in the visualization team. For this Weekly Chart, I gathered data from my favorite novel, “Mrs. Dalloway” by Virginia Woolf, about how time and space are used in its narration."
"When you think about the Fibonacci sequence, you probably imagine a swirling vortex of oscillating points stretching outwards to infinity. [...] Okay, no, obviously you don’t. Yet."
I love a good traffic simulation. This one is by the Los Angeles Times.
