Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

Basile Bouchon (French: [basil buʃɔ̃]) (or Boachon) was a textile worker in the silk center in Lyon who invented a way to control a loom with a perforated paper roll in 1725.[1] The son of an organ maker, Bouchon partially automated the tedious setting up process of the drawloom in which an operator lifted the warp threads using cords.
This development is considered to be the first industrial application of a semi-automated machine.
The cords of the warp were passed through the eyes of horizontal needles arranged to slide in a box. These were either raised or not depending on whether there was not or was a hole in the roll at that point.[2] This was similar to the piano roll developed at the end of the 19th century and may have been inspired by the patterns that were traditionally drawn on squared paper.
Three years later, his assistant Jean-Baptiste Falcon expanded the number of cords that could be handled by arranging the holes in rows and using rectangular cards that were joined together in an endless loop.
Though this eliminated mistakes in the lifting of threads, it still needed an extra operator to control it and the first attempt at automation was made by Jacques Vaucanson in 1745. But it was not until 1805 that the wildly successful Jacquard mechanism was finally produced.

In computer programming, an infinite loop (or endless loop) is a sequence of instructions that, as written, will continue endlessly, unless an external intervention occurs, such as turning off power via a switch or pulling a plug. It may be intentional. There is no general algorithm to determine whether a computer program contains an infinite loop or not; this is the halting problem.
An endless tape cartridge is a tape cartridge or cassette that contains magnetic audio tape that can be played in an endless loop, without the need to rewind to repeat.
The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic-tape sound-recording technology that was popular from the mid-1960s until the early 1980s, when the compact cassette, which antedated the 8-track system, surpassed it in popularity for recorded music. The format was commonly used in cars and was most popular in the United States and Canada, and to a lesser extent, in the United Kingdom, Ireland, and Japan. One advantage of the 8-track tape cartridge was that it could play continuously in an endless loop, and did not have to be ejected, turned around, and reinserted to play the entire tape. After about 80 minutes of playing time, the tape would start again at the beginning. Because of the loop, no rewind is possible; the only options the user has are: play, fast forward, record, and program (track) change. The Stereo 8 Cartridge was created in 1965 by a consortium led by Bill Lear of Lear Jet Corporation, along with Ampex, Ford Motor Company, General Motors, Motorola, and RCA Victor Records (RCA—Radio Corporation of America). While the 8-track format is now considered obsolete, some collectors refurbish cartridges and players, and some artists have continued to release music on 8-track, largely for the novelty factor. Cheap Trick's 2009 album The Latest was issued on 8-track, as was Dolly Parton's 2020 Christmas album A Holly Dolly Christmas, the latter including an exclusive bonus track.

Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
