The Hackers on Planet Earth (HOPE) conference series is a hacker convention sponsored by the security hacker magazine 2600: The Hacker Quarterly that until 2020 was typically held at Hotel Pennsylvania, in Manhattan, New York City. Occurring biennially in the summer, there have been twelve conferences to date with the most recent occurring July 20–23, 2018. HOPE 2020, originally planned to be held at St. John's University, was instead held as a nine-day virtual event from July 25 to August 2, 2020. HOPE features talks, workshops, demonstrations, tours, and movie screenings. HOPE was significantly inspired by the quadrennial Hack-Tic events in the Netherlands which also inspired the annual Chaos Communication Congress (C3) held in Germany. Summercon was also an influential predecessor.

Manhattan Mall is an inactive indoor shopping mall at 33rd Street and Sixth Avenue in Midtown Manhattan, New York City. There are entrances to the New York City Subway's 34th Street–Herald Square station and the PATH's 33rd Street station on the second basement level. The mall replaced the former flagship store of the Gimbels department store chain, which operated from 1910 to 1986. It opened in 1989 as a shopping center called A&S Plaza and was rebranded Manhattan Mall in 1995. Stern's department store occupied the anchor store space from 1995–2001. The upper floors were converted into office space in the 2000s decade, with the mall focusing on the first, second, and two basement levels instead. JCPenney operated the large anchor store from 2007 to 2020. The coronavirus pandemic hit the mall hard in 2020, with the remaining stores departing and the location relegated to being a dead mall. As of mid 2022, the mall area functions primarily as an expanded lobby for the offices of 100 w33rd st, allowing office tenants direct access from sixth ave as well as the local subway station. The EXPRESS store has been replaced with Aeropostale, but the southern end of the Manhattan Mall is still WIP.
