In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

File System Visualizer, also known as fsv, is a 3D file browser using OpenGL, written by Daniel Richard G. It is a clone of SGI's fsn file manager for IRIX systems, aimed to run on modern Linux and other Unix-like operating systems.[1] While not officially deprecated, the source code for the software has not been modified since 2001.[2]
It is capable of representing file systems in two ways:
In both of these modes, a standard 2D file tree is displayed on the left of the window. The mouse can be used to rotate the 3D representation of the file system, and an "Eagle Eye" function shows the representation from an overhead view. File System Visualizer is also capable of manipulating the files and directories it displays.
The 1993 film Jurassic Park has a scene that prominently features SGI's fsn, the original version of the utility that fsv clones.[3]

File System Visualizer, also known as fsv, is a 3D file browser using OpenGL, written by Daniel Richard G. It is a clone of SGI's fsn file manager for IRIX systems, aimed to run on modern Linux and other Unix-like operating systems. While not officially deprecated, the source code for the software has not been modified since 2001. It is capable of representing file systems in two ways: MapV mode: files and directories are represented as cuboids of equal height, with the size of the cuboid representing the size of the file or directory. TreeV mode: files and directories are shown in a more conventional file tree style, with links between parent directories and subdirectories, and columns of various height (indicating file size) on top of the directories to represent the files inside. In both of these modes, a standard 2D file tree is displayed on the left of the window. The mouse can be used to rotate the 3D representation of the file system, and an "Eagle Eye" function shows the representation from an overhead view. File System Visualizer is also capable of manipulating the files and directories it displays.
In computing, a keyboard controller is a device that interfaces a keyboard to a computer. Its main function is to inform the computer when a key is pressed or released. When data from the keyboard arrives, the controller raises an interrupt (a keyboard interrupt) to allow the CPU to handle the input. If a keyboard is a separate peripheral system unit (such as in most modern desktop computers), the keyboard controller is not directly attached to the keys, but receives scancodes from a microcontroller embedded in the keyboard via some kind of serial interface. In this case, the controller usually also controls the keyboard's LEDs by sending data back to keyboard through the wire. The IBM PC AT used an Intel 8042 chip to interface to the keyboard. This chip had two additional functions: it controlled access to the Intel 80286 CPU's A20 line in order to implement a workaround for a chip bug, and it was used to initiate a software CPU reset in order to allow the CPU to transition from protected mode to real mode because the 286 did not allow the CPU to go from protected mode to real mode unless the CPU is reset. The latter was a problem because the BIOS and services provided by real mode operating systems such as MS-DOS and similar operating systems could only be called by programs in real mode. These behaviors have been used by plenty of software that expects this behavior, and therefore keyboard controllers have continued controlling the A20 line and performing software CPU resets even when the need for a reset via the keyboard controller was obviated by the Intel 80386's ability to switch to real mode from protected mode without a CPU reset. The keyboard controller also handles PS/2 mouse input if a PS/2 mouse port is present.
Mouse Systems Corporation (MSC), formerly Rodent Associates, was founded in 1982 by Steve Kirsch. The company was responsible for bringing the first mouse to the IBM PC.
Mode 7 is a graphics mode on the Super Nintendo Entertainment System (Super NES) video game console that allows a background layer to be rotated and scaled, which may be done on a scanline-by-scanline basis to create many different depth effects. It also supports wrapping effects such as translation and reflection. The most famous of these effects is the application of a perspective effect (Figure 1) on a background layer by adjusting the layer's scale each scanline. This transforms the background layer into a two-dimensional (2D) horizontal texture-mapped plane that trades height for depth, achieving an impression of three-dimensional (3D) graphics. Mode 7 was one of Nintendo's prominent selling points for the Super NES platform in publications such as Nintendo Power and Super NES Player's Guide. Similar faux 3D techniques have been presented on a few 2D systems other than the Super NES, in select peripherals and games.
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.
