Video blogging, sometimes shortened to vlogging (pronounced 'vlogging', as opposed to 'v-logging') or vidding or vidblogging is a form of blogging for which the medium is video, and is a form of Web television. Entries often combine embedded video or a video link with supporting text, images, and other metadata. Entries can be recorded in one take or cut into multiple parts. It is also a very popular category on YouTube.
Video logs (vlogs) also often take advantage of web syndication to allow for the distribution of video over the Internet using either the RSS or Atom syndication formats, for automatic aggregation and playback on mobile devices and personal computers (See video podcast).
On January 2, 2000, Adam Kontras posted a video alongside a blog entry aimed at informing his friends and family of his cross-country move to Los Angeles in pursuit of show business, marking the first post on what would later become the longest-running video blog in history. In November of that year, Adrian Miles posted a video of changing text on a still image, coining the term vog to refer to his video blog. In 2004, Steve Garfield launched his own video blog and declared that year "the year of the video blog". In an effort to fulfill this prediction, Miles and Garfield soon joined their online colleagues Jay Dedman, Peter Van Dijck, Andreas Haugstrup Pedersen, and Christophe Bouten in creating a group on Yahoo! Groups devoted to video blogging.
In vector calculus, del is a vector differential operator, usually represented by the nabla symbol ∇. When applied to a function defined on a one-dimensional domain, it denotes its standard derivative as defined in calculus. When applied to a field (a function defined on a multi-dimensional domain), del may denote the gradient (locally steepest slope) of a scalar field, the divergence of a vector field, or the curl (rotation) of a vector field, depending on the way it is applied.
Strictly speaking, del is not a specific operator, but rather a convenient mathematical notation for those three operators, that makes many equations easier to write and remember. The del symbol can be interpreted as a vector of partial derivative operators, and its three possible meanings—gradient, divergence, and curl—can be formally viewed as the product of scalars, dot product, and cross product, respectively, of the del "operator" with the field. These formal products do not necessarily commute with other operators or products.
A photo booth is a vending machine or modern kiosk that contains an automated, usually coin-operated, camera and film processor. Today the vast majority of photo booths are digital. Traditionally photo booths contain a seat or bench designed to seat the one or two patrons being photographed. The seat is typically surrounded by a curtain of some sort to allow for some privacy and help avoid outside interference during the photo session. Once the payment is made, the photo booth will take a series of photographs (though most modern booths may only take a single photograph and print out a series of identical pictures). Before each photograph, there will be an indication, such as a light or a buzzer, that will signal the patron to prepare their pose. After the last photograph in the series (typically between 3 and 8) has been taken, the photo booth begins developing the film — a process that used to take several minutes in the old 'wet chemistry' booths, but is now typically accomplished in about 30 seconds with digital technology. The prints are then delivered to the customer.
