Digital geometry | Computer graphics data structures
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), pixel refers to a single scalar element of a multi-component representation (called a photosite in the camera sensor context, although sensel is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position. (Wikipedia).
Hi all. In the next series of tutorials we are going to start talking about mobile website design and the first concept you need to be familiar with is a pixel. If you already know what a pixel is, feel free to skip this tutorial.

7. Abstract Art In A Time Of Minification / Jenn Schiffer / ffconf 2017
aesthetic is a major component of any medium for art, including the web, but one thing that has been bothering me lately is: what happened to "view source"? are we destroying aesthetic for the sake of tooling and in spite of access to our industry????¿¿¿¿
