Crib barn

Crib barns were a popular type of barn found throughout the U.S. south and southeast regions. Crib barns were especially ubiquitous in the Appalachian and Ozark Mountain states of North Carolina, Virginia, Kentucky, Tennessee and Missouri and Arkansas.

Design

These barns were composed of multiple cribs, up to six, which were used for feed storage or livestock pens. Crib barn construction was somewhat simplistic compared to other types of barns, such as the prairie barn or the round barn, which gained popularity in American agriculture. Crib barns were most often built of unchinked logs and may or may not have included a hay loft depending on the specific barn. Unaltered examples of crib barns usually have roofs covered with undressed wood shingles, which, over time, were replaced with tin or asphalt. It is the rustic appearance of crib barns that cause them to stand out.

The most popular type of crib barn built in the Appalachian states was also the simplest to construct considering its size and stability. The "Double Crib" consisted of two cribs separated by a breezeway and covered by the same roof. This type of barn is the most common in Appalachia. The doors in this type of crib barn face either front or in, toward the breezeway. The loft, as is typical with crib barns that have lofts, is used for storage of feed and hay in this design of crib barn while the first floor is used for stabling. The breezeway, which essentially acted as a driveway which entered the barn was often used for threshing grain.

Bach (New Zealand)

A bach (pronounced 'batch') (/ˈbætʃ/; (also called a crib in the southern half of the South Island) is a small, often very modest holiday home or beach house. Baches are an iconic part of New Zealand history and culture, especially in the middle of the 20th century, where they symbolized the beach holiday lifestyle that was becoming more accessible to the middle class.

"Bach" was [thought to be] originally short for bachelor pad, but actually they often tended to be a family holiday home. An alternative theory for the origination of the word is that bach is Welsh for small, although the pronunciation of this word is somewhat different. Baches began to gain popularity in the 1950s as roads improved and the increasing availability of cars allowed for middle-class beach holidays, often to the same beach every year. With yearly return trips being made, baches began to spring up in many family vacation spots.

Construction

Post-World War II

They are almost always small structures, usually made of cheap or recycled material like fibrolite (asbestos sheets), corrugated iron or used timber. They were influenced by the backwoods cabins and sheds of the early settlers and farmers. Other baches used a caravan as the core of the structure, and built extensions on to that. Many cities were dismantling tram lines in the 1950s, and old trams were sometimes used as baches.

Known-plaintext attack

The known-plaintext attack (KPA) is an attack model for cryptanalysis where the attacker has access to both the plaintext (called a crib), and its encrypted version (ciphertext). These can be used to reveal further secret information such as secret keys and code books. The term "crib" originated at Bletchley Park, the British World War II decryption operation.

History

The usage "crib" was adapted from a slang term referring to cheating (e.g., "I cribbed my answer from your test paper.") A "crib" originally was a literal or interlinear translation of a foreign-language text — usually a Latin or Greek text — that students might be assigned to translate from the original language.

The idea behind a crib is that cryptologists were looking at incomprehensible ciphertext, but if they had a clue about some word or phrase that might be expected to be in the ciphertext, they would have a "wedge," a test to break into it. If their otherwise random attacks on the cipher managed to sometimes produce those words or (preferably) phrases, they would know they might be on the right track. When those words or phrases appeared, they would feed the settings they had used to reveal them back into the whole encrypted message to good effect.
