Snap (computer graphics)

In computer graphics, snapping allows an object to be easily positioned in alignment with grid lines, guide lines or another object, by causing it to automatically jump to an exact position when the user drags it to the proximity of the desired location.

Some CAD software provides a "Snap" pull-down menu with diverse options as preferences for the practice of the operation.

In Windows with the option snap enabled, vertical positioning of a window against the top edge of the screen causes it to change into full screen.

Jounce

In physics, jounce or snap is the fourth derivative of the position vector with respect to time, with the first, second, and third derivatives being velocity, acceleration, and jerk, respectively; hence, the jounce is the rate of change of the jerk with respect to time. Jounce is defined by any of the following equivalent expressions:

The following equations are used for constant jounce:

where

The notation (used in ) is not to be confused with the displacement vector commonly denoted similarly. Currently, there are no well-accepted designations for the derivatives of jounce. The fourth, fifth and sixth derivatives of position as a function of time are "sometimes somewhat facetiously" referred to as snap, crackle and pop respectively. Because higher-order derivatives are not commonly useful, there has been no consensus among physicists on the proper names for derivatives above jounce.

The dimensions of jounce are distance per (time to the power of 4). In SI units, this is "metres per quartic second", "metres per second per second per second per second", m/s⁴, m · s⁻⁴, or 100 Gal per second squared in CGS units. This pattern continues for higher order derivatives, with the 5th being m/s⁵.

VoIP spam

VoIP spam or SPIT (Spam over Internet Telephony) are bulk unsolicited, automatically dialled, pre-recorded phone calls using the Voice over Internet Protocol (VoIP). Telephone spam is comparable to E-mail spam, but due to its synchronous character, different mitigation methods are needed.

Voice over IP systems, like e-mail and other Internet applications, are susceptible to abuse by malicious parties who initiate unsolicited and unwanted communications. Telemarketers, prank callers, and other telephone system abusers are likely to target VoIP systems increasingly, particularly if VoIP supplants conventional telephony. The VoIP technology provides convenient tools (e.g. Asterisk and SIPp) and low-priced possibilities to place a large number of Spam calls.

The underlying technology driving this threat is Session Initiation Protocol (SIP). This technology has received significant support from most major telecommunication vendors, and is showing signs of becoming the industry standard for voice, video and other interactive forms of communication such as instant messaging and gaming.

Spit (nightclub)

Spit (alternately known as Uncle Sam's) was a nightclub and music venue located on Hempstead Turnpike in Levittown, New York. The club opened in 1978 and closed in 1992. Some well-known bands performed at the club including Madonna, Blue Öyster Cult and Duran Duran. Some performances were broadcast on WLIR radio. The building was set fire in 1994 by the owners in attempt to collect insurance. They were charged and convicted of arson.
