QUAD is a high-performance data compressor based on the LZ algorithms (LZ77, LZ78, LZW). It's designed to produce small files but still decompress fast and with little memory. QUAD is licensed under the LGPL.

A Zeppelin is a type of rigid airship named after the German inventor Ferdinand von Zeppelin who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874 and developed in detail in 1893. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word zeppelin came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins as bombers and as scouts, resulting in over 500 deaths in bombing raids in Britain.
LZ77 and LZ78 are the two lossless data compression algorithms published in papers by Abraham Lempel and Jacob Ziv in 1977 and 1978. They are also known as LZ1 and LZ2 respectively. These two algorithms form the basis for many variations including LZW, LZSS, LZMA and others. Besides their academic influence, these algorithms formed the basis of several ubiquitous compression schemes, including GIF and the DEFLATE algorithm used in PNG and ZIP.
In military terminology a landing zone (LZ) is an area where aircraft can land.
The Battle of Ia Drang was the first major battle between the United States Army and the People's Army of Vietnam (PAVN), as part of the Pleiku Campaign conducted early in the Vietnam War, at the eastern foot of the Chu Pong Massif in the central highlands of Vietnam, in 1965. It is notable for being the first large scale helicopter air assault and also the first use of Boeing B-52 Stratofortress strategic bombers in a tactical support role. Ia Drang set the blueprint for the Vietnam War with the Americans relying on air mobility, artillery fire and close air support, while the PAVN neutralized that firepower by quickly engaging American forces at very close range.
Operation Hastings was an American military operation in the Vietnam War. The operation was a qualified success in that it pushed the People's Army of Vietnam (PAVN) forces back across the Demilitarized Zone (DMZ). As the PAVN clearly did not feel constrained by the "demilitarized" nature of the DMZ, US military leadership ordered a steady build-up of U.S. Marines near the DMZ from 1966 to 1968.
Operation Sure Win 202 was a 1964 Army of the Republic of Vietnam (ARVN) operation carried out with US support. ARVN commandos were transported by U.S. helicopters behind entrenched Viet Cong (VC) positions, attacking them with shoulder fired rockets and flame throwers. Sniper teams then tracked the fleeing rebels and engaged them.
DELAG, acronym for Deutsche Luftschiffahrts-Aktiengesellschaft, was the world's first airline to use an aircraft in revenue service. It operated a fleet of zeppelin rigid airships manufactured by the Luftschiffbau Zeppelin Corporation. Its headquarters were located in Frankfurt, Germany.

LZ-3 is an autovía located on the island of Lanzarote in the Canary Islands. It serves as a ring road to the island's capital city, Arrecife.
The ZeppelinLZ 3 was a German experimental airship constructed in Friedrichshafen under the direction of Ferdinand von Zeppelin. It was first flown on 9 October 1906 and was later purchased by the German Army and operated as Z I until being retired in 1913. Before being purchased by the Army, LZ 3 made many flights and carried a number of influential passengers, including the German Crown Prince.
LZ4 is a lossless data compression algorithm that is focused on compression and decompression speed. It belongs to the LZ77 family of byte-oriented compression schemes.
The Zeppelin P Class was the first Zeppelin airship type to be produced in quantity after the outbreak of the First World War. Twenty-two of the type were built as well as twelve of a lengthened version, the Q Class. They were used for many of the airship bombing raids on the United Kingdom in 1915-16, for naval patrol work over the North Sea and Baltic and were also deployed on the eastern and south-eastern fronts.
Dmitri Sergeyevich Aliev is a Russian figure skater. He is the 2020 European champion and the 2020 Russian national champion. On the junior level, he is the 2017 World Junior silver medalist, the 2016–17 Junior Grand Prix Final champion, a two-time medalist at the 2016 Youth Olympics, and a two-time Russian national junior champion.
Landing Zone 1 and Landing Zone 2, also known as LZ-1 and LZ-2 respectively, are landing facilities on Cape Canaveral Space Force Station for recovering components of SpaceX's VTVL reusable launch vehicles. LZ-1 and LZ-2 were built on land leased in February 2015, on the site of the former Cape Canaveral Launch Complex 13. SpaceX built Landing Zone 2 at the facility to have a second landing pad, allowing two Falcon Heavy boosters to land simultaneously.
The LZ 85, tactical number L 45, also known as Zeppelin of Laragne by the French public, was a World War I R-Class zeppelin of the German Navy that carried out a total of 27 flights, including 3 raids on England and 12 reconnaissance missions.
Operation Paul Revere was a 3rd Brigade, 25th Infantry Division operation that took place west of Pleiku, lasting from 10 May to 1 August 1966.

Operation Imperial Lake was a U.S. Marine Corps, Republic of Korea Marine Corps and U.S. Army operation in the Quế Sơn District, Quảng Nam Province, South Vietnam that took place from 1 September 1970, to 7 May 1971. It was the last operation of the 1st Marine Division during the Vietnam War.
Operation Wayne Grey was an operation carried out by the United States Army, 1st Brigade, 4th Infantry Division and supporting elements, on March 1 to April 14, 1969. Its main objective was to cut off lines of communication and supply to the People's Army of Vietnam (PAVN) 24th and 66th Infantry Regiments as well as preventing them from retreating into Cambodia.
