It’s 9 a.m. on a typical morning in Chengdu and I’m awakened by the sound of my phone alarm. The phone is in my study, connected to my bedroom by sliding doors. I turn off the alarm, pick up my phone, and, like millions of people in China, the first thing I do is check my WeChat. At 9:07, I send my first message of the day.

Before 10 on a normal day in Chengdu, WeChat knows the following things about me: It knows roughly when I wake up, it knows who has messaged me and who I message, it knows what we talk about. It knows my bank details, it knows my address and it knows my coffee preference in the morning. It knows my biometric information; it knows the very contours of my face.

This article compares navigating a computer desktop without the desktop. That is, this article demonstrates how to use a terminal to move around and browse your computer as you would on a desktop, but from a terminal instead.

While the terminal may seem mysterious and intimidating at first, it's easy to learn once you realize that a terminal uses the same information as all of your usual applications. There are direct analogs for everything you do in a GUI to most of the everyday activities you do in a terminal. So instead of starting your journey with the shell by learning terminal commands, begin with everyday tasks that you're already familiar with.

In this post we’ll explore how we can derive logistic regression from Bayes’ Theorem. Starting with Bayes’ Theorem we’ll work our way to computing the log odds of our problem and the arrive at the inverse logit function. After reading this post you’ll have a much stronger intuition for how logistic

In the midst of the deep learning hype, p-values might not be the hottest topic in data science. However, association mapping remains a fundamental tool to justify and underpin scientific conclusions. Inspired by an approach for time series classification based on predictive subsequences (i.e shapelets [1]), we developed S3M, a method that identifies short time series subsequences that are statistically associated with a class or phenotype while tackling the multiple hypothesis problem.

Many games depend on content variety to tailor their gameplay experience. Having repetitive challenges can lead to player boredom, so designers generally aim to create an experience that is constantly engaging. Games usually consist of many facets such as levels, mechanics, graphics, sounds, etc. One of the most unique is level design. It does not introduce a new dimension in the game, instead, it is concerned with the arrangement of the existing elements. With the high demand for content in games, level design becomes a major task in game design. Its role is of pivotal importance, to the extent of being assigned to a different team than the one responsible for game and mechanics design, for games with large scopes.
