I recently saw a post from OpenCulture, that I explored, and tweeted about: the shortest known paper published in a serious math journal. The Shortest-Known Paper Published in a Serious Math Journal: Two Succinct Sentences https://t.co/6cjmgqOsDC via @openculture — Babis Τsourakakis (@Tsourolampis) March 21, 2017 I wrote few lines of C++ code to search for […]

Suppose there is an underlying 1 dimensional histogram stored in the cloud. As a concrete example, consider the distribution of bank deposits (x-axis is the amount of dollars, and the y-axis is the count of accounts). For simplicity let’s assume that all the amounts of money deposited are integers within the range . The histogram is queried by […]

    Here is an abstract from an interview with Edsger Dijkstra about his shortest path algorithm. There’s a curious story behind your “shortest path” algorithm. In 1956 I did two important things, I got my degree and we had the festive opening of the ARMAC.c We had to have a demonstration. Now the ARRA, […]

  One should always be drunk. That’s all that matters; That’s our one imperative need. So as not to feel Time’s Horrible burden that breaks your shoulders and bows You own, you must get drunk without ceasing. But what with? With wine, with poetry, or with Virtue, as you choose. But get drunk. And if, […]

Let  be independent uniform random variables from , and consider the random variable . Computing the expectation is a routine computation: . However, there a slick way of computing this expectation. Let be another uniform random variable in . Consider the probability . On the one hand due to symmetry, it is equal to , on […]
