Your location for sale

Companies collect and aggregate location data from millions of people’s phones. Then that data gets sold in a multibillion-dollar market. Jon Keegan and Alfred Ng for The Markup report on who’s doing the collecting and where your data goes: Once a person’s location data has been collected from an app and it has entered the location data marketplace, it can be sold over and over again, from the data providers...

Derek Thompson for The Atlantic highlights recent research comparing mortality in America against rates in Europe: According to a new working paper released by the National Bureau of Economic Research, Americans now die earlier than their European counterparts, no matter what age you’re looking at. Compared with Europeans, American babies are more likely to die before they turn 5, American teens are more likely to die before they turn 20,...

Check your presumptions while you’re reading this chart about Israel’s vaccination campaign

On July 30, Israel began administering third doses of mRNA vaccines to targeted groups of people. This decision was controversial since there is no science to support it. The policymakers do have educated guesses by experts based on best-available information. By science, I mean actual evidence. Since no one has previously been given three shots, there can be no data on which anyone can root such a decision. Nevertheless, the...

Testing the TikTok algorithm

The Wall Street Journal tested out the TikTok algorithm with bots to see how quickly the app converged towards a user’s pre-specified interests. As viewing time of videos as the main signal, and to nobody’s surprise (I think), it only took a couple of hours for TikTok to narrow down interests. This is how most social services work these days? The concerning part is that almost all TikTok videos are...

An AI chatbot to talk to the dead

Joshua Barbeau fed an AI chatbot with old texts from his fiancee who had died years before, so that he could talk to her again. Jason Fagone for the San Francisco Chronicle wrote about Barbeau’s experience: As Joshua continued to experiment, he realized there was no rule preventing him from simulating real people. What would happen, he wondered, if he tried to create a chatbot version of his dead fiancee?...

The graphic presents four measures of wellbeing in society - life expectancy, infant mortality rate, murder rate and prison population. The primary goal is to compare nations across those metrics. The focus is on comparing how certain nations (or subgroups) rank against each other, as indicated by the relative...

I am sure this will be a useful reference for my future self, but I am also hoping it might be useful for one or the other person out there. It’s split into 19 lessons over...
