Question:
Stallman was born to Alice Lippman, a school teacher, and Daniel Stallman, a printing press broker, in 1953 in New York City. Stallman had a difficult relationship with his parents, as his father had a drinking habit and verbally abused his stepmother. He later came to describe his parents as "tyrants". He was interested in computers at a young age; when Stallman was a pre-teen at a summer camp, he read manuals for the IBM 7094.
As a first-year student at Harvard University in fall 1970, Stallman was known for his strong performance in Math 55. He was happy: "For the first time in my life, I felt I had found a home at Harvard."  In 1971, near the end of his first year at Harvard, he became a programmer at the MIT Artificial Intelligence Laboratory, and became a regular in the hacker community, where he was usually known by his initials, RMS (which was the name of his computer accounts). Stallman received a bachelor's degree in physics (magna cum laude) from Harvard in 1974.  Stallman considered staying on at Harvard, but instead he decided to enroll as a graduate student at MIT. He pursued a doctorate in physics for one year, but left that program to focus on his programming at the MIT AI Laboratory.  While working (starting in 1975) as a research assistant at MIT under Gerry Sussman, Stallman published a paper (with Sussman) in 1977 on an AI truth maintenance system, called dependency-directed backtracking. This paper was an early work on the problem of intelligent backtracking in constraint satisfaction problems. As of 2009, the technique Stallman and Sussman introduced is still the most general and powerful form of intelligent backtracking. The technique of constraint recording, wherein partial results of a search are recorded for later reuse, was also introduced in this paper.  As a hacker in MIT's AI laboratory, Stallman worked on software projects such as TECO, Emacs for ITS, and the Lisp machine operating system (the CONS of 1974-1976 and the CADR of 1977-1979--this latter unit was commercialized by Symbolics and LMI starting around 1980). He would become an ardent critic of restricted computer access in the lab, which at that time was funded primarily by the Defense Advanced Research Projects Agency. When MIT's Laboratory for Computer Science (LCS) installed a password control system in 1977, Stallman found a way to decrypt the passwords and sent users messages containing their decoded password, with a suggestion to change it to the empty string (that is, no password) instead, to re-enable anonymous access to the systems. Around 20% of the users followed his advice at the time, although passwords ultimately prevailed. Stallman boasted of the success of his campaign for many years afterward.

Question:
Carousel is the second musical by the team of Richard Rodgers (music) and Oscar Hammerstein II (book and lyrics). The 1945 work was adapted from Ferenc Molnar's 1909 play Liliom, transplanting its Budapest setting to the Maine coastline. The story revolves around carousel barker Billy Bigelow, whose romance with millworker Julie Jordan comes at the price of both their jobs. He participates in a robbery to provide for Julie and their unborn child; after it goes tragically wrong, he is given a chance to make things right.
The cast album of the 1945 Broadway production was issued on 78s, and the score was significantly cut--as was the 1950 London cast recording. Theatre historian John Kenrick notes of the 1945 recording that a number of songs had to be abridged to fit the 78 format, but that there is a small part of "Soliloquy" found on no other recording, as Rodgers cut it from the score immediately after the studio recording was made.  A number of songs were cut for the 1956 film, but two of the deleted numbers had been recorded and were ultimately retained on the soundtrack album. The expanded CD version of the soundtrack, issued in 2001, contains all of the singing recorded for the film, including the cut portions, and nearly all of the dance music. The recording of the 1965 Lincoln Center revival featured Raitt reprising the role of Billy. Studio recordings of Carousel's songs were released in 1956 (with Robert Merrill as Billy, Patrice Munsel as Julie, and Florence Henderson as Carrie), 1962 and 1987. The 1987 version featured a mix of opera and musical stars, including Samuel Ramey, Barbara Cook and Sarah Brightman. Kenrick recommends the 1962 studio recording for its outstanding cast, including Alfred Drake, Roberta Peters, Claramae Turner, Lee Venora, and Norman Treigle.  Both the London (1993) and New York (1994) cast albums of the Hytner production contain portions of dialogue that, according to Hischak, speak to the power of Michael Hayden's portrayal of Billy. Kenrick judges the 1994 recording the best all-around performance of Carousel on disc, despite uneven singing by Hayden, due to Sally Murphy's Julie and the strong supporting cast (calling Audra McDonald the best Carrie he has heard). The Stratford Festival issued a recording in 2015.

Question:
A big band is a type of musical ensemble that usually consists of ten or more musicians with four sections: saxophones, trumpets, trombones, and a rhythm section. Big bands originated during the early 1910s and dominated jazz in the early 1940s when swing was most popular. The term "big band" is also used to describe a genre of music. One problem with this usage is that it overlooks the variety of music played by these bands.
Before 1914, social dance in America was dominated by steps such as the waltz and polka. As jazz migrated from its New Orleans origin to Chicago and New York City, energetic, suggestive dances traveled with it. During the next decades, ballrooms filled with people doing the jitterbug and Lindy Hop. The dance duo Vernon and Irene Castle popularized the foxtrot while accompanied by the orchestra of James Reese Europe.  One of the first bands to accompany the new rhythms was led by a drummer, Art Hickman, in San Francisco in 1916. Hickman's arranger, Ferde Grofe, wrote arrangements in which he divided the jazz orchestra into sections that combined in various ways. This intermingling of sections became a defining characteristic of big bands. In 1919, Paul Whiteman hired Grofe to use similar techniques for his band. Whiteman was educated in classical music, and he called his new band's music symphonic jazz. The methods of dance bands marked a step away from New Orleans jazz. With the exception of Jelly Roll Morton, who continued playing in the New Orleans style, bandleaders paid attention to the demand for dance music and created their own big bands. They incorporated elements of Broadway, Tin Pan Alley, ragtime, and vaudeville.  Duke Ellington led his band at the Cotton Club in Harlem. Fletcher Henderson's career started when he was persuaded to audition for a job at Club Alabam in New York City, which eventually turned into a job as bandleader at the Roseland Ballroom. At these venues, which themselves gained notoriety, bandleaders and arrangers played a greater role than they had before. Hickman relied on Ferde Grofe, Whiteman on Bill Challis. Henderson and arranger Don Redman followed the template of King Oliver, but as the 1920s progressed they moved away from the New Orleans format and transformed jazz. They were assisted by a band full of talent: Coleman Hawkins on tenor saxophone, Louis Armstrong on cornet, and multi-instrumentalist Benny Carter, whose career lasted into the 1990s.
