Pump

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.

Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy to perform mechanical work by moving the fluid. Pumps operate via many energy sources, including manual operation, electricity, engines, or wind power, come in many sizes, from microscopic for use in medical applications to large industrial pumps.

Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis.

Pump (skateboarding)

Pumping is a skateboarding technique used to accelerate without the riders' feet leaving the board. Pumping can be done by turning or on a transition, like a ramp or quarter pipe. When applied to longboards, it is also known as Long distance skateboard pumping or LDP. Pumping is a technique similar to pumping a surfboard.

Transition

Transition pumping can only be done when there is a slope differential between the front and rear wheels. That is to say, it can only be done at the top and bottom of any ramp, but can be done through the entire pipe. The rider should actually push downward on the truck with the greatest slope under the wheels. On the top of a ramp the front wheels should be pushed, and at the bottom the rear trucks should be pushed. On a pipe the weight should be applied to the rear truck throughout the entire transition.

Slalom

Flatland pumping is essentially carving with the proper amount of weight application in order to gain momentum. It involves shifting one's weight in sync with the board's movements in order to gain momentum, like pivoting, but with all four wheels on the ground. By keeping the proper timing, the proper foot position, and the proper set up, one can yield great results.

Pump.io

Pump.io (pronounced "pump eye-oh") is a general purpose activity streams engine that can be used as a federated social networking protocol which "does most of what people really want from a social network". Started by Evan Prodromou, it is a follow up to StatusNet;Identi.ca, which was the largest StatusNet service, switched to pump.io in June 2013. However, while StatusNet offered functionality similar to Twitter, pump.io offers much more general purpose social networking, and is being adopted by other types of web applications, such as MediaGoblin.

Technology

Designed to be much more lightweight and efficient than its StatusNet predecessor, Pump.io is written in Node.js and uses Activity Streams as the format for commands and to transfer data via a simple REST inbox API.
