#482: quantum of sollazzo – 2022
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’ visualization of the state of gas storage in EU countries. Unsurprisingly, it’s caught everyone’s attention.
‘till next week,
Giuseppe @puntofisso
