Statistical Formulas For Programmers
By Evan Miller DRAFT: May 19, 2013 Being able to apply statistics is like having a secret superpower. Where most people see averages, you see confidence intervals. When someone says “7 is greater than 5,” you declare that they're really the same. In a cacophony of noise, you hear a cry for help. Unfortunately, not enough programmers have this superpower. As my modest contribution to developer-kind, I've collected together the statistical formulas that I find to be most useful; this page presents them all in one place, a sort of statistical cheat-sheet for the practicing programmer. Most of these formulas can be found in Wikipedia, but others are buried in journal articles or in professors' web pages. Send suggestions and corrections to emmiller@gmail.com Table of Contents 1. One of the first programming lessons in any language is to compute an average. 1.1 Corrected Standard Deviation The standard deviation is a single number that reflects how spread out the data actually is. Where: SE=s√N 2. 3.

Platforms
The Aalto University Platforms are designed to initiate and coordinate multi- and interdisciplinary research and teaching in some thematic area. The Platforms bring together Aalto's competences in the area, and increase Aalto's external visibility. Primary purposes of the Platforms are to facilitate and strengthen the industry-academia collaboration, and to increase the internal cooperation within the University. The Platforms and their agendas are born through a bottom-up process, and aim at concrete benefits for the participating actors.

Johnny Depp
Johnny Depp [ˈd͡ʒɑni dɛp][1] est un acteur, réalisateur, guitariste, chanteur, scénariste et producteur de cinéma américain, né le 9 juin 1963 à Owensboro (Kentucky). D'une manière générale, les personnages les plus atypiques qu'il incarne sont aussi audacieux qu'originaux et se démarquent du commun des mortels. Au début des années 1990, il a commencé à collaborer avec celui qui est devenu son réalisateur fétiche et son ami, Tim Burton, avec lequel il a tourné huit films. De 1998 à 2012, il forme un couple iconique avec la chanteuse et actrice française Vanessa Paradis.

Essential Math for Games Programmers
As the quality of games has improved, more attention has been given to all aspects of a game to increase the feeling of reality during gameplay and distinguish it from its competitors. Mathematics provides much of the groundwork for this improvement in realism. And a large part of this improvement is due to the addition of physical simulation. Creating such a simulation may appear to be a daunting task, but given the right background it is not too difficult, and can add a great deal of realism to animation systems, and interactions between avatars and the world. This tutorial deepens the approach of the previous years' Essential Math for Games Programmers, by spending one day on general math topics, and one day focusing in on the topic of physical simulation. Topics for the various incarnations of this tutorial can be found below. Current Materials Slides The latest available versions of the slides for the math tutorials at GDC 2015 are as follows: Past Materials Core Mathematics

Radically Cheap: The Story of Pat Delany, Open Source Machine Tools Advocate
The ex-rancher felt empathy push his problem-solving mind into a new direction. He looked back at all those years he had tinkered with junk-built machine tools in his workshop — all that time spent poring over scans of antique how-to magazines looking for clever hacks to avoid having to buy new tools. It was fun and sometimes necessary for me, he thought, but what I’ve created here can also help many people. This is the story of Pat Delany, one of the leading creative voices in Appropriate Technology — technology that is small-scale, decentralized, labor-intensive, energy-efficient, environmentally sound, and locally controlled. This 78-year-old grandfather came to the field as an outsider, inspired by a second-hand description of a news photo. But his visionary home-built machine-tool designs now have the potential to help millions bootstrap themselves out of poverty. Delany had worked with machines for his entire life and built many machines for himself. The MultiMachine Lost Wisdom

Compute the sign of an integer The last expression above evaluates to sign = v >> 31 for 32-bit integers. Alternatively, if you prefer the result be either -1 or +1, then use: sign = +1 | (v >> (sizeof(int) * CHAR_BIT - 1)); // if v < 0 then -1, else +1 On the other hand, if you prefer the result be either -1, 0, or +1, then use:
