Scott:

In Search Of Missing Us Suicides by Scott Alexander – “Among US states, there’s a clear relationship between gun ownership rates and suicide rates, but not between gun ownership rates and homicide rates. You might conclude guns increase suicides but not homicides. Then you might predict that the gun-loving US would be an international outlier in suicides but not homicides. In fact, it’s the opposite. Why?”

Highlights From The Comments On Basic Jobs by Scott Alexander – Lots of currated comments about ‘Guaranteed Basic Jobs’ vs Universal Basic Income. Scott responds to several of them.

Monopoly: A Manifesto And Fact Post by Sarah Constantin – Tons of graphs showing how bad the great stagnation has been. GDP growth measured in commodities has been anemic, more industry concentration and barriers to entry, very low productivity growth. Some thoughts on why solving the problem of increasing monopoly is hard.

Dear Graduating Sixth Graders by Duncan Sabien – Duncan’s speech at a sixth grade graduation. A major focus is that in the path 12-13 year olds were often already working and would be preparing for marriage. People that age have not gotten less capable, just less driven and motivated.

Silence Around Test Scores Serves the Privileged by Daniel Friedman – In defense of talking about your SAT and IQ score. “Surely it’s no coincidence that the only admissions criteria it’s taboo to discuss is the one that money can’t buy. Surely it’s no coincidence that the means by which undesirable minorities squeezed their way into elite spaces has become something that we’re supposed to treat as shameful. Surely it’s no coincidence that the one thing that reveals the mediocrity of the children of the rich and powerful has become taboo to talk about.”

Misc:

Understanding How To Implement A Character Based RNN Language Model by Eli Bendersky – “In a single gist, Andrej Karpathy did something truly impressive. In a little over 100 lines of Python – without relying on any heavy-weight machine learning frameworks – he presents a fairly complete implementation of training a character-based recurrent neural network (RNN) language model; this includes the full backpropagation learning with Adagrad optimization. I love such minimal examples because they allow me to understand some topic in full depth, connecting the math to the code and having a complete picture of how everything works. In this post I want to present a companion explanation to Karpathy’s gist, showing the diagrams and math that hide in its Python code.”
