Universal Disk Format (UDF) is a profile of the specification known as ISO/IEC 13346 and ECMA-167 and is an open vendor-neutral file system for computer data storage for a broad range of media. In practice, it has been most widely used for DVDs and newer optical disc formats, supplanting ISO 9660. Due to its design, it is very well suited to incremental updates on both recordable and (re)writable optical media. UDF is developed and maintained by the Optical Storage Technology Association (OSTA).

Normally, authoring software will master a UDF file system in a batch process and write it to optical media in a single pass. But when packet writing to rewritable media, such as CD-RW, UDF allows files to be created, deleted and changed on-disc just as a general-purpose filesystem would on removable media like floppy disks and flash drives. This is also possible on write-once media, such as CD-R, but in that case the space occupied by the deleted files cannot be reclaimed (and instead becomes inaccessible).

Multi-session mastering is also possible in UDF, though some implementations may be unable to read disks with multiple sessions.

V (or V: The Original Miniseries) is a two-part American science-fiction television miniseries, written and directed by Kenneth Johnson. First shown in 1983, it initiated the science-fiction franchise concerning aliens known as the "Visitors" trying to gain control of Earth and of the ways the populace reacts.

The Smart File System (SFS) is a journaling filesystem used on Amiga computers and AmigaOS-derived operating systems (though some support also exists for IBM PC compatibles). It is designed for performance, scalability and integrity, offering improvements over standard Amiga filesystems as well as some special or unique features.

The phantom time hypothesis is a historical conspiracy theory asserted by Heribert Illig. First published in 1991, it hypothesizes a conspiracy by the Holy Roman Emperor Otto III, Pope Sylvester II, and possibly the Byzantine Emperor Constantine VII, to fabricate the Anno Domini dating system retrospectively, in order to place them at the special year of AD 1000, and to rewrite history to legitimize Otto's claim to the Holy Roman Empire. Illig believed that this was achieved through the alteration, misrepresentation and forgery of documentary and physical evidence. According to this scenario, the entire Carolingian period, including the figure of Charlemagne, is a fabrication, with a "phantom time" of 297 years (AD 614–911) added to the Early Middle Ages.

A jerrycan (also written as jerry can or jerrican) is a robust liquid container made from pressed steel. It was designed in Germany in the 1930s for military use to hold 20 litres (4.4 imp gal; 5.3 US gal) of fuel. The development of the jerrycan was a significant improvement on earlier designs, which required tools and funnels to use, and it contained many innovative features for convenience of use and robustness. After widespread use by both Germany and the Allies during the Second World War, today similar designs are used worldwide for fuel and water containers, some of which are also produced in plastic. The designs usually emulate the original steel design and are still known as jerrycans. The original design of jerrycan and various derivatives remain in widespread military use.

The Centennial Light is the world's longest-lasting light bulb, burning since 1901, and almost never switched off. It is at 4550 East Avenue, Livermore, California, and maintained by the Livermore-Pleasanton Fire Department. Due to its longevity, the bulb has been noted by The Guinness Book of World Records, Ripley's Believe It or Not!, and General Electric.

A hemispherical combustion chamber is a type of combustion chamber in a reciprocating internal combustion engine with a domed cylinder head. An engine featuring this type of hemispherical chamber is known as a hemi engine.

🔗 Theatre 🔗 Elizabethan theatre

The Parnassus plays are three satiric comedies, or full-length academic dramas, each divided into five acts. They date from between 1598 and 1602. They were performed in London by students for an audience of students as part of the Christmas festivities of St John's College at Cambridge University. It is not known who wrote them.

The titles of the three plays are

• The Pilgrimage to Parnassus
• The Return from Parnassus
• The Return from Parnassus: Or the Scourge of Simony

The second and third plays are sometimes referred to as Part One and Part Two of The Return from Parnassus.

The trilogy raises an Elizabethan question: After college – what comes next? Francis Bacon in his essay "Of Seditions and Troubles" pointed to a 16th-century problem – universities were producing more scholars than there were opportunities for them. The University Wits – Lily, Marlowe, Green, Peele, Nashe and Lodge – were scholars who found employment in theatre, not perhaps their first choice, but there was little else for them. Their great education tended to discourage them from taking up the humble trades of their fathers. The Parnassus plays may not provide a solution, but they at least illustrated the fears of such ambitious young scholastic dreamers.

For the most part, the plays follow the experiences of two students, Philomusus and Studioso. The first play tells the story of two pilgrims on a journey to Parnassus. The plot is an allegory understood to represent the story of two students progressing through the traditional course of education known as the trivium. The accomplishment of their education is represented by Mount Parnassus. The second play drops the allegory and describes the two graduates' unsuccessful attempts to make a living, as does the third play, which is the only one that was contemporaneously published. New in the third play is the serious treatment of issues regarding censorship.

It has been said that this trilogy of plays "in originality and breadth of execution, and in complex relationship to the academic, literary, theatrical and social life of the period, ranks supreme among the extant memorials of the university stage", and that they are "among the most inexplicably neglected key documents of Shakespeare's age".

The eastern coyote (Canis latrans var.) is a wild North American canine of both coyote and wolf parentage. The hybridization likely first occurred in the Great Lakes region, as western coyotes moved east. It was first noticed during the early 1930s to the late 1940s, and likely originated in the aftermath of the extirpation of the gray wolf in southeastern Ontario, Labrador and Quebec, thus allowing coyotes to colonize the former wolf ranges and mix with the remnant wolf populations. This hybrid is smaller than the eastern wolf and holds smaller territories, but is larger and holds more extensive home ranges than the typical western coyote.

🔗 Mammals

Tuffi (born 1946, India – died 1989, Paris, France) was a female Asian elephant that became famous in West Germany during 1950 when she accidentally fell from the Wuppertal Schwebebahn into the River Wupper underneath.

On 21 July 1950, the circus director Franz Althoff (de) had Tuffi, then four years old, traveled on the suspended monorail in Wuppertal, as a publicity stunt. The elephant trumpeted wildly and ran through the carriage, broke through a window and fell 12 metres (39 ft) down into the River Wupper, suffering only minor injuries. A panic had broken out in the carriage and some passengers were injured. Althoff helped the elephant out of the water. Both the circus director and the official who had allowed the ride were fined. Tuffi was sold to Cirque Alexis Gruss (fr) in 1968; she died there in 1989.

No photograph of the incident is known; a widely circulated postcard picture is a montage. A building near the location of the incident, between the stations Alter Markt and Adlerbrücke, features a painting of Tuffi. A local milk-factory has chosen the name as a brand.

The Wuppertal tourist information keeps an assortment of Tuffi-related souvenirs, local websites show original pictures.

In 1970 Marguerita Eckel and Ernst-Andreas Ziegler published a children's picture book about the incident titled Tuffi und die Schwebebahn (“Tuffi and the suspension railway”).
