Sock!

Sock! is an album by saxophonist Gene Ammons compiling sessions recorded between 1954 and 1962 and released on the Prestige label in 1965.

Reception

Allmusic awarded the album 1½ stars with its review by Scott Yanow stating, "Sock! is basically a mess. The ten brief songs are strung together with no thought given to sound or segues, and the material itself is pretty weak".

Track listing

Sock

A sock is an item of clothing worn on the feet and often covering the ankle and some part of the calf. Some type of shoe or boot is typically worn over socks. In ancient times, socks were made from leather or matted animal hair. In the late 16th century, machine-knit socks were first produced. Until 1800 both hand knitting and machine knitting were used to produce socks, but after 1800, machine knitting became the predominant method.

One of the roles of socks is absorbing perspiration. The foot is among the heaviest producers of sweat in the body, as it can produce over 0.25 US pints (0.12 l) of perspiration per day. Socks help to absorb this sweat and draw it to areas where air can evaporate the perspiration. In cold environments, socks made from wool insulate the foot and decrease the risk of frostbite. Socks are worn with sport shoes (typically white-coloured socks) and dress shoes (typically dark-coloured socks). In addition to the numerous practical roles played by socks, they are also a fashion item, and they are available in myriad colours and patterns.

Unix domain socket

A Unix domain socket or IPC socket (inter-process communication socket) is a data communications endpoint for exchanging data between processes executing on the same host operating system. Like named pipes, Unix domain sockets support transmission of a reliable stream of bytes (SOCK_STREAM, compare to TCP). In addition, they support ordered and reliable transmission of datagrams (SOCK_SEQPACKET), or unordered and unreliable transmission of datagrams (SOCK_DGRAM, compare to UDP). The Unix domain socket facility is a standard component of POSIX operating systems.

The API for Unix domain sockets is similar to that of an Internet socket, but rather than using an underlying network protocol, all communication occurs entirely within the operating system kernel. Unix domain sockets use the file system as their address name space. Processes reference Unix domain sockets as file system inodes, so two processes can communicate by opening the same socket.

In addition to sending data, processes may send file descriptors across a Unix domain socket connection using the sendmsg() and recvmsg() system calls. This allows the sending processes to grant the receiving process access to a file descriptor for which the receiving process otherwise does not have access. This can be used to implement a rudimentary form of capability-based security. For example, this allows the Clam AntiVirus scanner to run as an unprivileged daemon on Linux and BSD, yet still read any file sent to the daemon's Unix domain socket.
