Problem: Grace Brewster Murray Hopper (nee Murray; December 9, 1906 - January 1, 1992) was an American computer scientist and United States Navy rear admiral. One of the first programmers of the Harvard Mark I computer, she was a pioneer of computer programming who invented one of the first compiler related tools. She popularized the idea of machine-independent programming languages, which led to the development of COBOL, an early high-level programming language still in use today. Hopper had attempted to enlist in the Navy during World War II, but she was rejected by the military because she was 34 years of age and thus too old to enlist.

In 1949, Hopper became an employee of the Eckert-Mauchly Computer Corporation as a senior mathematician and joined the team developing the UNIVAC I. Hopper also served as UNIVAC director of Automatic Programming Development for Remington Rand. The UNIVAC was the first known large-scale electronic computer to be on the market in 1950, and was more competitive at processing information than the Mark I.  When Hopper recommended the development of a new programming language that would use entirely English words, she "was told very quickly that [she] couldn't do this because computers didn't understand English." Her idea was not accepted for 3 years, and she published her first paper on the subject, compilers, in 1952. In the early 1950s, the company was taken over by the Remington Rand corporation, and it was while she was working for them that her original compiler work was done. The program was known as the A compiler and its first version was A-0.  In 1952 she had an operational link-loader, which at the time was referred to as a compiler. She later said that "Nobody believed that," and that she "had a running compiler and nobody would touch it. They told me computers could only do arithmetic." She goes on to say that her compiler "translated mathematical notation into machine code. Manipulating symbols was fine for mathematicians but it was no good for data processors who were not symbol manipulators. Very few people are really symbol manipulators. If they are they become professional mathematicians, not data processors. It's much easier for most people to write an English statement than it is to use symbols. So I decided data processors ought to be able to write their programs in English, and the computers would translate them into machine code. That was the beginning of COBOL, a computer language for data processors. I could say "Subtract income tax from pay" instead of trying to write that in octal code or using all kinds of symbols. COBOL is the major language used today in data processing."  In 1954 Hopper was named the company's first director of automatic programming, and her department released some of the first compiler-based programming languages, including MATH-MATIC and FLOW-MATIC.

Question:
Paul Duane Beauregard, (born January 12, 1977) better known by his stage name DJ Paul, is an American rapper, record producer, DJ, songwriter and entrepreneur from Memphis, Tennessee. He is a founding member of hip-hop group Three 6 Mafia and Da Mafia 6iX and the half-brother of the late rapper Lord Infamous. DJ Paul started his career in the late 1980s as a DJ and released a number of solo tapes, as well as three collaboration albums with Lord Infamous as The Serial Killaz. Juicy J was introduced and the three founded the group Three 6 Mafia, going on to achieve national success in the late 1990s and early 2000s.
In early 2013, DJ Paul focused on performing as a DJ, and created a DJ duo, called S.I.M. (Sex is Mandatory). The group created a number of live sets, as well as remixes to songs, such as Just Blaze & Baauer's "Higher".  In late 2013, Paul and Lord Infamous were discussing creating a sequel to their 1993 album Come with Me 2 Hell, when the latter came with the idea to try and reunite the whole Three 6 Mafia crew. Infamous brought back Crunchy Black, Koopsta Knicca and Gangsta Boo, and the five of them reunited as "Da Mafia 6ix" with plans to release an album in 2014. On November 12, 2013, Da Mafia 6ix released their first mixtape 6ix Commandments. The tape was almost entirely produced by DJ Paul and featured Yelawolf, 8Ball & MJG, Krayzie Bone, Bizzy Bone, SpaceGhostPurrp and HCP affiliates Lil Wyte, Skinny Pimp and La Chat, among others. Juicy J and Project Pat also appeared as surprise guests on the posse song "Body Parts", being credited just as "& more" in the track listing.  DJ Paul collaborated on a mixtape titled Clash Of Da Titans with fellow Memphis producer Drumma Boy that was released on October 23, 2013, and on a free EP, called Black Fall, with rapper Yellawolf, which they put out for Halloween on October 31, 2013. On November 26, 2013, DJ Paul released Volume 16: The Original Masters, a remaster of his 1994 mixtape 4 Da Summer of '94. It was revealed on the PSYR17 EP given away at the 2014 Gathering Of The Juggalos that DJ Paul plans to release his next solo album "Master Of Evil" on Psychopathic Records in 2015. He later confirmed it himself on the 28th of August on The Australia underground hip hop podcast "The Underground Podcast", as well as on the outro song to The Killjoy Club's debut album "Reindeer Games".  DJ Paul has been announced to play South by Southwest showcase in Austin, Texas on March 21, 2015.  On August 19, 2016 DJ Paul announced that he has signed to Yelawolf's Slumerican Records.
