Data delivered over an unencrypted channel is insecure, untrustworthy, and trivially intercepted. We owe it to our users to protect the security, privacy, and integrity of their data — all data must be encrypted while in flight and at rest. Historically, concerns over performance have been the common excuse to avoid these obligations, but today that is a false dichotomy. Let's dispel some myths.

Any traditional introductory statistics course will teach students the definitions of modes, medians and means. But, because introductory courses can’t assume that students have much mathematical maturity, the close relationship between these three summary statistics can’t be made clear. This post tries to remedy that situation by making it clear that all three concepts arise as specific parameterizations of a more general problem.

Finding planets orbiting nearby stars has been a holy grail in astronomy for more than 400 years. We began working on this problem 30 years ago, at a time when there were no known extrasolar planets. In late 1995 we began routinely finding planets around the nearest stars. Since then we have found several hundred planets, including the first sub-saturn mass planet, the first neptune mass planet, the first terrestrial mass planet, the first multiple planet system, and the first transiting planet.

In this post, I implement the Held-Karp algorithm, an exact algorithm to the Travelling Salesman Problem (TSP). The algorithm is then ported to run on the GPU in browser, through WebGL, using gpgpu.js, where it experiences up to a 10-100x speedup at the higher node counts.

But no one actually involved in the ticket scalping industry thinks that banning bots will do much to slow down the secondary market. Seven years after his Los Angeles office was raided by shotgun-wielding FBI agents, Lowson told me he's switched teams. Now, he's out to expose the secrets of the ticket industry in a bid to make sure tickets are sold directly to their fans.

Hazlewood’s music blasted off into the psychedelic, flower-power stratosphere as the ’60s progressed. But Trouble Is A Lonesome Town is steeped in warped, Gothic Americana of a much earlier vintage. It’s full of cheerful ditties about morbid subjects. Hazlewood introduces us to Trouble’s sharply dressed undertaker in “We All Make The Flowers Grow,” an upbeat number about how time and the lurking shadow of the Grim Reaper will soon reduce us all to plant food. But the tone is cheeky and irreverent, not despairing:

This post introduces eigenvectors and their relationship to matrices in plain language and without a great deal of math. It builds on those ideas to explain covariance, principal component analysis, and information entropy.
