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... my screenprinting toot. Really?!
This issue reaches you on the first day in my new role. Feeling a mixture of excitement and terror as I write that :-)
'till next week,
I've covered the excellent Mapping Diversity project before, a look at how street names are chosen. The team behind it has now [released the full dataset](https://www.europeandatajournalism.eu/cp_data_news/mapping-diversity-full-dataset-release/ used in the analysis.
"A diminishing pool of Americans are eligible to join the Army, Navy, or Air Force. An even smaller pool want to."
A chart of why young people don't want to join, you'll soon realise that it would be great to see the same data split by gender.

"Tips & tricks , inspired by DuckDB, Parquet files and OpenCoesione". This is an automated tranlation of this amazing article in Italian by data guru Andrea Borruso. It covers DuckDB, Miller, and VisiData.
You will remember that last week I linked to my own step-by-step how to for a map of distances in QGIS (it's here in case you missed it). Totò Fiandaca has greatly improved it and made it dynamic, using the shapefile of all mayoralties, showing how to assign each mayoralty. It's in Italian and here is automatically translated into English, but the images should be relatively self-explanatory.
This is an online book which says it is "a complete introduction to the web as a platform for 3D graphics using the three.js WebGL library, from one of the core three.js developers."
By developer Lewy Blue, it looks pretty comprehensive and interactive.
The popular network analysis tool has launched a web version called Gephi Lite.
You can now use QGIS geoprocessing algorithms in the R programming language, thanks to the CRAN release of the qgisprocess library. As Robin Lovelace notes: "You can now call any of ~1000 geo algorithms in QGIS + plugins from #rstats. "
"A modern yet simple multi-platform video cutter and joiner."
"An Overview of Retrieval Augmented Generation (RAG). Demystifying and deconstructing Q&A bots that work over your data."

"Prigozhin’s press service actively responds via Telegram to questions asked by journalists. Questions are mostly posted as screenshots, responses are mostly posted as audio messages, other posts include video. How do we turn these into something that can be searched and analysed?"
By Osservatorio Balcani Caucaso's Giorgio Comai.
This website does exactly what it says on the tin, and it seems to be doing it really well. It uses data from open-meteo. The source code is on GitHub (albeit with a slightly restrictive CC BY-SA-NC).
"States now offer a vast menu of personalized plate options for a dizzying array of organizations, professions, sports teams, causes and other groups."
