Not OP but here's why I think it's a great choice: it's the kind of book you could read many times and still not understand every nuance. There's a joke in the literary world that …

Since the GPS signal is just disciplining a local oscillator, it would have to be a sustained outage before drift starts to really matter. But yeah there is a point where it would …

Couldn't agree more on the mechanism design front. There are so many dimensions to the problem - especially for US equities - that the design becomes quite nuanced and tradeoffs ha…

There's a protocol being worked on called STIR/SHAKEN to address robocalls [0]. It's more like website / browser certificate PKI than spam filtering. Some of the major US telcos ar…
