Problem: Background: Thomas Wesley Pentz (born November 10, 1978), better known by his stage name Diplo, is an American DJ, record producer, rapper and songwriter based in Los Angeles, California. He is the co-creator and lead member of the electronic dancehall music project Major Lazer, and along with producer and DJ Skrillex, part of the electronic duo Jack U. He founded and manages record company Mad Decent, as well as co-founding the non-profit organization Heads Decent. Among other jobs, he has worked as a school teacher in Philadelphia.
Context: Diplo was born on November 10, 1978, in Tupelo, Mississippi, the son of Barbara Jean (nee Cox) and Thomas Pentz. He is of German and English descent. The influence of home-grown rap played a key role in helping shape his production style. He spent the majority of his youth in Miami, where he got a taste for the characteristic Miami bass. He began attending the University of Central Florida in 1997, and then moved to Philadelphia to continue his studies at Temple University, where he first garnered attention as a DJ. After frequently running into fellow DJ Low Budget, the two began throwing parties under the Hooked on Hollertronix moniker in 2003 as a way of maintaining control of what they were able to play during DJ gigs in Philadelphia. The success of these parties allowed the two to release mixtapes, both separate and together, gathering acclaim across the country. One such mixtape, Never Scared, was named one of the New York Times top ten albums of 2003, and the Hollertronix name became synonymous with parties featuring guests like Maluca Mala, Bun B, Spank Rock, M.I.A., among others. Hollertronix's sound has been described as "disparate genres to be smashed together for maximum attention-grabbing impact" an aesthetic which takes from the "organic, cohesive, whole" aesthetic of acts such as Bun B, Lil Jon, Drama, M.I.A., Bjork, Busta Rhymes, and others. Diplo accentuated the club aesthetic of his Hollertronix music for a more reflective sound on his solo debut, Florida, which was released on the Ninja Tune imprint, Big Dada Records. The album Florida was pressed twice, first with a CD and the second with a CD and DVD. The DVD was created by System D-128, another artist who has collaborated with Diplo on some audio and video projects. Before Florida's DVD accompaniment, another DVD surfaced called Diplo: "Banned in Libya" which was released by Money Studies, the first label to release a solo project by Diplo under his original DJ name Diplodocus. It was a 45 rpm record called "Thingamajawn" for which there is also a music video System D-128 directed. Similar to the Florida DVD, "Banned in Libya" is an experimental audio and video mix of some of Diplo's original music blended with a number of other unidentified sources. His particular affinity for one genre of music called baile funk, or favela funk, would spawn a series of mixtapes (Favela on Blast, Favela Strikes Back), which served to bring the Brazilian dance music of the ghettos to the United States. It was not long before his Hooked on Hollertronix parties would provide him the success necessary to move to the next logical step and build a studio where music would become his full-time focus. With this goal in mind, Diplo built "The Mausoleum," a video studio, recording studio, record label office, gallery, and event space in Philadelphia. Since its inception, The Mausoleum has become the home to recordings by artists like Christina Aguilera, Shakira, M.I.A., Santigold, Spank Rock, Plastic Little, Blaqstarr, Paper Route Gangstaz, and hosted concerts by Glass Candy, Skream, Boys Noize, Nicos Gun, and more.
Question: Did he work with anyone else notable?
Answer: the Hollertronix name became synonymous with parties featuring guests like Maluca Mala, Bun B, Spank Rock, M.I.A., among others.

Problem: Background: Affirmed (February 21, 1975 - January 12, 2001) was an American Thoroughbred racehorse who was the eleventh winner of the United States Triple Crown of Thoroughbred Racing. Affirmed was also known for his famous rivalry with Alydar, whom he met ten times, including in all three Triple Crown races. Affirmed was the last horse to win the Triple Crown for a 37-year period, which was ended in 2015 by American Pharoah. Affirmed won fourteen Grade
Context: As a four-year-old in 1979, Affirmed started the season with a third place in the Malibu Stakes and a second in the San Fernando Stakes. He had a five race losing sequence prior to starting in the Charles H. Strub Stakes at Santa Anita Park. Laz Barrera replaced Cauthen with Pincay and Affirmed didn't lose again and would dominate the handicaps the rest of the year. Affirmed won the Strub Stakes, and then ran in the Santa Anita Handicap against Exceller, who had defeated Seattle Slew in 1978. Affirmed won easily, running the 1 1/4 miles in 1:58 3/5, setting a stakes record in California's most important stakes race that stood until 2014. Affirmed then went to Hollywood Park, where he won the Californian Stakes, carrying 132 pounds, he then won the Hollywood Gold Cup in a three horse finish, from Sirlad and Text, setting an all time earnings record and running the 1 1/4 miles in a fast 1:58 2/5. Affirmed picked up the Woodward Stakes at Belmont Park, and then faced one more all-time great horse, three-year-old Spectacular Bid, in the Jockey Club Gold Cup, also at Belmont. Spectacular Bid, like Alydar, preferred to run off the pace, and once again, Affirmed was allowed to set a slow pace, going the first half mile in 49 seconds. Spectacular Bid issued challenges at Affirmed, but Affirmed won. Spectacular Bid was undefeated during the rest of his racing career. Affirmed was named Horse of the Year and the American Champion Older Male Horse of 1979, having won 7 of 9 starts with 1 second and 1 third as a four-year-old and earning $1,148,800. In his career, Affirmed earned a then record $2,393,818 (the first Thoroughbred in North America to win over $2 million) with 22 wins, 5 seconds and 1 third from 29 starts. His trainer, Laz Barrera, once said: "Affirmed is greater than Secretariat, or any Triple Crown winner, because only Affirmed had to face Alydar."
Question: When did he start winning again?
Answer:
Laz Barrera replaced Cauthen with Pincay and Affirmed didn't lose again and would dominate the handicaps the rest of the year.
