Ornamental Hairpin (簪, Kanzashi) is a 1941 Japanese comedy-drama film written and directed by Hiroshi Shimizu. It is based on the short story Yottsu no yubune (四つの湯槽, lit. "The four bathtubs") by Masuji Ibuse.

The ship's cat has been a common feature on many trading, exploration, and naval ships dating to ancient times. Cats have been carried on ships for many reasons, most importantly to control rodents. Vermin aboard a ship can cause damage to ropes, woodwork, and more recently, electrical wiring. Also, rodents threaten ships' stores, devour crews' foodstuff, and could cause economic damage to ships' cargo such as grain. They are also a source of disease, which is dangerous for ships that are at sea for long periods of time. Rat fleas are carriers of plague, and rats on ships were believed to be a primary vector of the Black Death.

Cats naturally attack and kill rodents, and their natural ability to adapt to new surroundings made them suitable for service on a ship. In addition, they offer companionship and a sense of home, security and camaraderie to sailors away from home.

CipherSaber is a simple symmetric encryption protocol based on the RC4 stream cipher. Its goals are both technical and political: it gives reasonably strong protection of message confidentiality, yet it's designed to be simple enough that even novice programmers can memorize the algorithm and implement it from scratch. According to the designer, a CipherSaber version in the QBASIC programming language takes just sixteen lines of code. Its political aspect is that because it's so simple, it can be reimplemented anywhere at any time, and so it provides a way for users to communicate privately even if government or other controls make distribution of normal cryptographic software completely impossible.

A train ferry is a ship (ferry) designed to carry railway vehicles. Typically, one level of the ship is fitted with railway tracks, and the vessel has a door at the front and/or rear to give access to the wharves. In the United States, train ferries are sometimes referred to as "car ferries", as distinguished from "auto ferries" used to transport automobiles. The wharf (sometimes called a "slip") has a ramp, and a linkspan or "apron", balanced by weights, that connects the railway proper to the ship, allowing for the water level to rise and fall with the tides.

While railway vehicles can be and are shipped on the decks or in the holds of ordinary ships, purpose-built train ferries can be quickly loaded and unloaded by roll-on/roll-off, especially as several vehicles can be loaded or unloaded at once. A train ferry that is a barge is called a car float or rail barge.

A stick bomb is a (mechanical) spring-loaded device constructed out of flat sticks woven together under a bending moment. Other names for stick bombs include Chinese stick puzzles, Cobra wave, and frame bombs. Stick bombs are created for fun and as art, not for any practical use.

The Hindenburg Omen was a proposed technical analysis pattern, named after the Hindenburg disaster of May 6, 1937. It was created by Jim Miekka, who believed that it portended a stock market crash.

We (Russian: Мы, romanized: My) is a dystopian novel by Russian writer Yevgeny Zamyatin, written 1920–1921. The novel was first published as an English translation by Gregory Zilboorg in 1924 by E. P. Dutton in New York. The novel describes a world of harmony and conformity within a united totalitarian state. George Orwell claimed that Aldous Huxley's 1931 Brave New World must be partly derived from We, but Huxley denied it.

The AlphaSmart was a brand of portable, battery powered, word-processing keyboards manufactured by NEO Direct, Inc. (formerly Renaissance Learning, Inc, formerly AlphaSmart, Inc., formerly Intelligent Peripheral Devices, Inc.). Originally released in 1993, the first AlphaSmart models were intended for writing on-the-go and could be plugged into a computer to transfer saved written text. The units' portability and long battery life made them valuable to journalists, writers, and students. Later models expanded functionality by spell-checking, running applications, and accessing wireless printers.

The last model, Neo 2, was released in 2007, and production was discontinued by the company in late September 2013, although the company still offers support and software to existing users.
