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.

CommonLoops (the Common Lisp Object-Oriented Programming System;[1] an acronym reminiscent of the earlier Lisp OO system "Loops" for the Interlisp-D system[2]) is an early programming language which extended Common Lisp to include Object-oriented programming functionality and is a dynamic object system which differs from the OOP facilities found in static languages such as C++ or Java. Like New Flavors, CommonLoops supported multiple inheritance, generic functions and method combination. CommonLoops also supported multi-methods and made use of metaobjects. CommonLoops and New Flavors were the primary ancestors of CLOS.[3] CommonLoops was supported by a portable implementation known as Portable CommonLoops (PCL) which ran on all Common Lisp implementations of the day.

CommonLoops (the Common Lisp Object-Oriented Programming System; an acronym reminiscent of the earlier Lisp OO system "Loops" for the Interlisp-D system) is an early programming language which extended Common Lisp to include Object-oriented programming functionality and is a dynamic object system which differs from the OOP facilities found in static languages such as C++ or Java. Like New Flavors, CommonLoops supported multiple inheritance, generic functions and method combination. CommonLoops also supported multi-methods and made use of metaobjects. CommonLoops and New Flavors were the primary ancestors of CLOS. CommonLoops was supported by a portable implementation known as Portable CommonLoops (PCL) which ran on all Common Lisp implementations of the day.
The Common Lisp Object System (CLOS) is the facility for object-oriented programming in ANSI Common Lisp. CLOS is a dynamic object system which differs radically from the OOP facilities found in more static languages such as C++ or Java. CLOS was inspired by earlier Lisp object systems such as MIT Flavors and CommonLoops, although it is more general than either. Originally proposed as an add-on, CLOS was adopted as part of the ANSI standard for Common Lisp and has been adapted into other Lisp dialects such as EuLisp or Emacs Lisp.
Robert Tappan Morris (born November 8, 1965) is an American computer scientist and entrepreneur. He is best known for creating the Morris worm in 1988, considered the first computer worm on the Internet. Morris was prosecuted for releasing the worm, and became the first person convicted under the then-new Computer Fraud and Abuse Act (CFAA). He went on to cofound the online store Viaweb, one of the first web applications, and later the venture capital funding firm Y Combinator, both with Paul Graham, Jessica Livingston and Trevor Blackwell. He later joined the faculty in the department of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology (MIT), where he received tenure in 2006. He was elected to the National Academy of Engineering in 2019.
Common Lisp (CL) is a dialect of the Lisp programming language, published in American National Standards Institute (ANSI) standard document ANSI INCITS 226-1994 (S2018) (formerly X3.226-1994 (R1999)). The Common Lisp HyperSpec, a hyperlinked HTML version, has been derived from the ANSI Common Lisp standard. The Common Lisp language was developed as a standardized and improved successor of Maclisp. By the early 1980s, several groups were already at work on diverse successors to MacLisp: Lisp Machine Lisp (aka ZetaLisp), Spice Lisp, NIL and S-1 Lisp. Common Lisp sought to unify, standardize, and extend the features of these MacLisp dialects. Common Lisp is not an implementation, but rather a language specification. Several implementations of the Common Lisp standard are available, including free and open-source software and proprietary software products. Common Lisp is a general-purpose, multi-paradigm programming language. It supports a combination of procedural, functional, and object-oriented programming paradigms. As a dynamic programming language, it facilitates evolutionary and incremental software development, with iterative compiling into efficient runtime programs. This incremental development is often done interactively without interrupting the running application. It also supports optional type annotation and casting, which can be added as needed at the later profiling and optimization stages, to permit the compiler to generate more efficient code. For instance, fixnum can hold an unboxed integer in a range supported by the hardware and implementation, permitting more efficient arithmetic than on big integers or arbitrary precision types. Similarly, the compiler can be told on a per-module or per-function basis which type of safety level is wanted, using optimize declarations. Common Lisp includes the Common Lisp Object System (CLOS), an object system that supports multiple dispatch (multimethods) and method combinations. It is often implemented with a metaobject protocol. Common Lisp is extensible through standard features such as Lisp macros (code transformations) and reader macros (input parsers for characters). Common Lisp provides partial backwards compatibility with Maclisp and John McCarthy's original Lisp. This allows older Lisp software to be ported to Common Lisp.
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.
