Question: The Wallflowers are an American rock band formed in Los Angeles in 1989 by singer-songwriter Jakob Dylan and guitarist Tobi Miller. The band has gone through a number of personnel changes but has remained centered on Dylan. After releasing their eponymous debut album in 1992, the Wallflowers released what would become their best-known and highest-selling album, Bringing Down the Horse in 1996, which featured songs such as "One Headlight" and "6th Avenue Heartache". They went on to release an additional three albums before going on a seven-year hiatus, beginning in 2006.

In 2001, Jakob Dylan began writing for the Wallflowers' fourth album, Red Letter Days. Later that year while on tour with John Mellencamp, the band began recording using portable equipment. Some recording was also done at keyboardist Rami Jaffee's house. Once the band was finished touring for the year they began recording the bulk of the new record at Jackson Browne's studio in Santa Monica. By the time the Wallflowers had gotten into Browne's studio, Michael Ward had left the band, leaving them without a lead guitarist for the recording process. Dylan took on much of the lead guitar duties with Mike McCready, Rusty Anderson and Val McCallum also contributing on guitar. Moe Z M.D., who had been touring with Mellencamp, contributed additional percussion and background vocals to the album.Red Letter Days was produced by founding Wallflowers member Tobi Miller along with Bill Appleberry. Recording continued through the new year and was completed on April 12, 2002. The album was mixed by Tom Lord-Alge, who had mixed the band's previous two albums. Mixing was completed on May 15, 2002.  While the Wallflowers were working on Red Letter Days, they recorded a cover of the Beatles' 1965 song "I'm Looking Through You" for the soundtrack to the 2001 film I Am Sam. The soundtrack was released on January 8, 2002.  The first single from the Red Letter Days, "When You're On Top," was released to radio on August 16, 2002. A music video directed by Marc Webb followed. After a few false starts, Red Letter Days was released on November 5, 2002. The album was met with mixed to positive reviews. Many critics noted the harder rock sound and catchy melodies used throughout the album. Commercial performance was relatively mixed as well, peaking at No.32 on the Billboard 200. Around the time of Red Letter Days' release the Wallflowers embarked on a monthlong U.S. tour stretching into early December. After another U.S. tour in January 2003, the Wallflowers toured in several European countries in February including Spain, Italy, Germany and Great Britain. After this tour, the Wallflowers' drummer since 1995, Mario Calire announced he was parting ways with the band.  In 2003, the Wallflowers were featured on the soundtrack for the film American Wedding. The band recorded a cover of Van Morrison's 1970 song "Into the Mystic". The film's music department weren't able to secure the licensing rights to use Morrison's version so they enlisted the Wallflowers to cover the song. Both versions of the song were, however, featured in the film.

Question: 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.

Throughout much of her later career, Hopper was much in demand as a speaker at various computer-related events. She was well known for her lively and irreverent speaking style, as well as a rich treasury of early war stories. She also received the nickname "Grandma COBOL".  While she was working on a Mark II Computer at a US Navy research lab in Dahlgren, Virginia in 1947, her associates discovered a moth that was stuck in a relay; the moth impeded the operation of the relay. While neither Hopper nor her crew mentioned the phrase "debugging" in their logs, the case was held as an instance of literal "debugging." For many years, the term bug had been in use in engineering. The remains of the moth can be found in the group's log book at the Smithsonian Institution's National Museum of American History in Washington, D.C.  Grace Hopper is famous for her nanoseconds visual aid. People (such as generals and admirals) used to ask her why satellite communication took so long. She started handing out pieces of wire that were just under one foot long (11.80 inches = 300 millimeters)--the distance that light travels in one nanosecond. She gave these pieces of wire the metonym "nanoseconds." She was careful to tell her audience that the length of her nanoseconds was actually the maximum speed the signals would travel in a vacuum, and that signals would travel more slowly through the actual wires that were her teaching aids. Later she used the same pieces of wire to illustrate why computers had to be small to be fast. At many of her talks and visits, she handed out "nanoseconds" to everyone in the audience, contrasting them with a coil of wire 984 feet long, representing a microsecond. Later, while giving these lectures while working for DEC, she passed out packets of pepper, calling the individual grains of ground pepper picoseconds.  Jay Elliot described Grace Hopper as appearing to be "'all Navy', but when you reach inside, you find a 'Pirate' dying to be released".
