1990 is the eleventh album by American singer-songwriter Daniel Johnston. It was released through record label Shimmy Disc, it was intended that all tracks would be studio recordings. However, Johnston's ongoing problems with mental illness prevented him from completing an album's worth of sessions; as a result, the album is compiled from home recordings and live performances. Johnston alludes to this in the film The Angel and Daniel Johnston – Live at the Union Chapel when he mentions that the album had intended to be called 1989, but they had not been able to release it that year. All tracks are written except as noted.

With his colleagues at the Office for Science and Society, he pioneered the McGill COurses ONline initiative. A proponent of massive open online courses, Harpp thinks students can benefit from having access these academic opportunities: "What if the best organic chemistry course, was put on by somebody from, the University of Illinois, why shouldn’t we?"Harpp is interested in academic integrity.

He followed up on his research on the prevalence of cheating by university students by inventing a computer program that spots cheating in multiple-answer exams. Use of the software, with the introduction of multiple versions of each exam, is credited to eliminating this type of cheating at McGill's: "I think 90 per cent of the students who tend to cheat will and say,'Nah.'"Harpp did his Bachelor of Arts at Middlebury College, his Masters at Wesleyan University and his Ph.
