FAQ: What's the difference between a gyro and an accelerometer? Do I need both? [Marc Ramsey gave a fantastically clear and concise answer to a question that's asked here every week, so I'm going to reprint it here with some slight edits as a FAQ that we can link to from the front page.] Q: What's the difference between a gyro and an accelerometer? Do I need both? An accelerometer measures acceleration. A 3-axis accelerometer will tell you the orientation of a stationary platform relative to earth's surface, once that platform starts moving, however, things get more complicated. If the platform is in free-fall, it will show zero acceleration. A gyro measures rate of rotation around a particular axis. So, in a nutshell: Accelerometers are right in the long term but wrong (noisy) in the short term. But even that only works in for pitch and roll. GPS has a relatively slow update rate (1 to 10 Hz) and is subject to short term errors. Infra-red horizon sensing "copilots" are inexpensive and work fairly well as long as they have a clear view of the horizon.
GUI Architectures There have been many different ways to organize the code for a rich client system. Here I discuss a selection of those that I feel have been the most influential and introduce how they relate to the patterns. Graphical user interfaces have become a familiar part of our software landscape, both as users and as developers. Looking at it from a design perspective they represent a particular set of problems in system design - problems that have led to a number of different but similar solutions. My interest is identifying common and useful patterns for application developers to use in rich-client development. In this essay I want to explore a number of interesting architectures and describe my interpretation of their most interesting features. To some extent you can see this essay as a kind of intellectual history that traces ideas in UI design through multiple architectures over the years. Forms and Controls To explore it, and indeed the other architectures, I'll use a common example.
Packagist Number of Internet Users (2016) Around 40% of the world population has an internet connection today (view all on a page ). In 1995, it was less than 1%. The number of internet users has increased tenfold from 1999 to 2013. The first billion was reached in 2005. The second billion in 2010. The third billion in 2014.

This Open Source Digital Condom Will Literally Shock You The condom has hardly changed in a hundred years, which is pretty ridiculous if you consider how few people actually like the damn things. A lot of people, in fact, are so unhappy with the timeworn rubber, they eschew using it at all—a problem a couple of researchers out of Georgia Tech think can be solved with electronics. Fraz Peer and Andrew Quitmeyer created a prototype of an open source, digital condom that's literally wired with electrodes along the side of the sleeve and hooked up to a microcontroller for power. The researchers bravely tested the sex gadget on themselves, as well as others, and apparently people found the resulting sensation to be "pleasurable, comforting, and exciting"—which I can only assume was after the initial terror and awkwardness of getting your manhood mildly electrocuted. Peer and Quitmeyer created two DIY versions of the Eel, one that's a rolled out existing condom rigged up with electrodes and the other that's basically a conductive sock. @meghanneal
