Tongue-in-cheek
The tongue-in-cheek figure of speech is used to imply that a statement or other production is humorously or otherwise not seriously intended, and it should not be taken at face value. The facial expression typically indicates that one is joking or making a mental effort. In the past, it may also have indicated contempt, but that is no longer common.
By 1842, the phrase had acquired its contemporary meaning, indicating that a statement was not meant to be taken seriously. Early users of the phrase include Sir Walter Scott in his 1828 The Fair Maid of Perth.
History
Putting one's tongue into a cheek was formerly used to signify contempt. For example, in Tobias George Smollett's The Adventures of Roderick Random, which was published in 1748, the eponymous hero is taking a coach to Bath and apprehends a highwayman. This provokes an altercation with a less brave passenger:
A similar usage appears in 1828 in The Fair Maid of Perth by Sir Walter Scott, "The fellow who gave this all-hail thrust his tongue in his cheek to some scapegraces like himself."
Truncated cube
In geometry, the truncated cube, or truncated hexahedron, is an Archimedean solid. It has 14 regular faces (6 octagonal and 8 triangular), 36 edges, and 24 vertices.
If the truncated cube has unit edge length, its dual triakis octahedron has edges of lengths 2 and 
.
Area and volume
The area A and the volume V of a truncated cube of edge length a are:
Orthogonal projections
The truncated cube has five special orthogonal projections, centered, on a vertex, on two types of edges, and two types of faces: triangles, and octagons. The last two correspond to the B2 and A2Coxeter planes.
Spherical tiling
The truncated cube can also be represented as a spherical tiling, and projected onto the plane via a stereographic projection. This projection is conformal, preserving angles but not areas or lengths. Straight lines on the sphere are projected as circular arcs on the plane.
Cartesian coordinates
The following Cartesian coordinates define the vertices of a truncated hexahedron centered at the origin with edge length 2ξ:

Goa'uld technology in Stargate
This is a list of Goa'uld technologies in the Stargate franchise. The Goa'uld are the main adversaries for most of the run of Stargate SG-1. They scavenged or conquered most of their advanced technologies from other races. However, there are innovators amongst the Goa'uld; Anubis and Ba'al in particular have been depicted with a great deal of technological ingenuity. Rather than being designed as practical, many Goa'uld devices, such as the staff weapon, are designed to have higher visual impact, meant to intimidate and reinforce their position as gods to their followers. Some pieces of Goa'uld technology, such as the hand device and the healing device, respond only to mental commands and require naqahdah in the bloodstream of the user to operate.

GNU Core Utilities
The GNU Core Utilities or coreutils is a package of GNU software containing reimplementations for many of the basic tools, such as cat, ls, and rm, used on Unix-like operating systems. It is a combination of a number of earlier packages, including textutils, shellutils, and fileutils, along with some other miscellaneous utilities.
GNU coreutils capabilities
The GNU core utilities support long options as parameters to the commands, as well as (unless the POSIXLY_CORRECT environment variable is set) the relaxed convention allowing options even after the regular arguments. Note that this environment variable enables a different functionality in BSD.
