Data bite back: a Harvard lesson

June 7, 2017
By

New York Times reports that Harvard rescinded admission offers to 10 students (link). These kids allegedly engaged in horrible behavior on "private" chatrooms online. Not reported is how Harvard admission officers got a hold of such information. Is it possible there are jealous classmates? I am not condoning the bad behavior - I put this link up to remind people: (a) no data are private, not even "deleted" data (b)…

The Times agrees on privacy and kind of on fake news business

May 11, 2017
By

The New York Times Magazine has been publishing some pieces that directly relate to a couple of my blog posts. In this article, Amanda Hess noticed that "privacy became a commodity for the rich and powerful." This echoes my blog post on "Data is the next frontier of equal rights." Hess discussed the asymmetry and hypocrisy of the situation whereby the same businesses and business executives that are wantonly stripping…

That fake news business

May 4, 2017

When Hillary Clinton unexpectedly lost the election in November 2016, it was high time for pundits to espouse their pet theories for the shocking losses suffered by the Democrats at all levels of government. The usual suspects were put on parade, such as “Bernie Bros” who abstained from voting and the “deplorables” who voted against their own interests. For the first time, two unlikely entities faced scrutiny: the social-media giant,…

Data sleaze: Uber and beyond

April 26, 2017
By

There has been a barrage of negative publicity related to Uber recently. The latest salvo is a long article in the New York Times (link). This piece focuses on Uber's CEO, who was trained as a computer engineer, but my interest lies primarily in several revelations about how Uber collects and uses customer data. The key episode picked up by various outlets (e.g. TechCrunch, Wired) involves Uber "secretly identifying and…

Reorientation in the French election

Financial Times has this chart up about the voters for the National Front, which is Marie Le Pen's party. I find the chart very hard to decipher, even though I usually like the dot plot format. The first thing to...

My pre-existing United boycott, and some musing on randomness and fairness

April 12, 2017
By

You probably already saw the video - if not, do yourself a favor, and search for "man forcibly removed from overbooked United flight." Other than the video evidence, which is damning, we don't have many facts, other than assertions made by various parties, repeated endlessly on social media and mainline media. Some facts, such as the United CEO claiming the passenger was "belligerent," is an assault on the meaning of…

Confused by machines, or spooked by the machine-makers

March 29, 2017
By

This New York Times article draws attention to real trends in the financial investments industry but gets completely lost in the smoke around those pushing "machines" and "data". The trend most concerning to the investments industry is the sustained, large-scale outflow of money from "actively-managed" funds, mutual funds being the biggest category of such. The industry makes loads of money from management fees by promoting the idea that investors are…
