Ping (networking utility)

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer and back. The name comes from active sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water; however, the backronym "PING" meaning "Packet InterNet Groper" has been in use since early days in computing for testing and measuring networks and the Internet.

Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP echo reply. It measures the round-trip time from transmission to reception, reporting errors and packet loss. The results of the test usually include a statistical summary of the response packets received, including the minimum, maximum, the mean round-trip times, and usually standard deviation of the mean.

Ping (blogging)

In blogging, a ping is an XML-RPC-based push mechanism by which a weblog notifies a server that its content has been updated. An XML-RPC signal is sent from the weblog to one or more "Ping Server(s)" (controlled by the weblog) to notify a list of their "Services" of new content on the weblog.

A Ping Server may notify multiple services when pinged;

The technology was first introduced by Dave Winer to Weblogs.com in October 2001. Today, most blog authoring tools automatically ping one or more servers each time the blogger creates a new post or updates an old one.

Open ping servers, like Moreover Technologies' Weblogs.com, let other web services subscribe to a list of blogs that have recently pinged them. Blog search engines can provide fresh results very quickly by polling only the newly updated blogs. Similarly, aggregators use results from ping servers to tell subscribers which items on their subscription lists have fresh material.

Run, Joe, Run

Run, Joe, Run was a Saturday-morning television program that aired on NBC from 1974 to 1976. It centered on Joe, a German Shepherd dog in the military's K-9 corps, and his master, Sergeant Will Corey (played by Arch Whiting). One day, during training, Joe was falsely accused of attacking his master, a crime for which the dog would be put to sleep as punishment. However, he escaped before being killed and a $200 bounty was put on his head.

Sgt. Corey believed Joe was innocent and also pursued him, hoping to find Joe before the authorities did. While on the run, Joe helped people he encountered.

During the show's second season, Sgt. Corey, having never found Joe (although he always came close), was called back to duty. Joe then teamed with a hiker, Josh McCoy (played by Chad States), and continued to help others, all the while still on the run.

The show was considered as a cross between Lassie and The Fugitive. Like The Fugitive, and later, The Incredible Hulk, it centered on a falsely accused person (in this case, the "person" was a dog) running from authorities and helping out people he meets along the way. The show was produced by D'Angelo Productions, which also produced the NBC young adult drama, Westwind, and other live-action series for Saturday mornings.
