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 Count's excellent SQL Tutorial canvas.
This week we welcome a new sponsor – the Richmond CDO Forum, a residential conference for Chief Data Officers which will be in September 2024. Really happy to have them on board. Details below.
'till next week,
Giuseppe @puntofisso

Hashing
"As a programmer, you use hash functions every day. They're used in databases to optimise queries, they're used in data structures to make things faster, they're used in security to keep data safe. Almost every interaction you have with technology will involve hash functions in one way or another. Hash functions are foundational, and they are everywhere."
This is a great intro, and it's beautifully interactive.
Geospatial Data Science with Earth Engine and Geemap
"Geemap is intended for students and researchers, who would like to utilize the Python ecosystem of diverse libraries and tools to explore Google Earth Engine. It is also designed for existing GEE users who would like to transition from the GEE JavaScript API to Python API. Geemap provides an interactive graphical user interface for converting GEE JavaScripts to Python scripts without the need to write any code. It can save users a lot of time and effort by providing a simple interface for exploring and visualizing Earth Engine datasets."

Train or car?
A Twitter thread by Jules Grandin of Les Echos shows the time-saving of car vs train for a select few French cities. Some are remarkably better connected by train than others, which shows in a huge time difference.

Atmospheric Carbon Dioxide Tagged by Source
"Carbon dioxide (CO2) is the most prevalent greenhouse gas driving global climate change. However, its increase in the atmosphere would be even more rapid without land and ocean carbon sinks, which collectively absorb about half of human emissions every year. Advanced computer modeling techniques in NASA's Global Modeling and Assimilation Office allow us to disentangle the influences of sources and sinks and to better understand where carbon is coming from and going to."
