Nachos, in their simplest form, are usually tortilla chips covered in melted cheese. First created in 1943 by Ignacio "Nacho" Anaya, the original nachos consisted of fried tortilla chips covered with melted cheese and jalapeño peppers. The first ballpark nachos were served at Arlington Stadium in Arlington, Texas. The International Day of the Nacho is celebrated on October 19th with the International Nacho Festival held at Piedras Negras, Coahuila, Mexico.

Not Another Completely Heuristic Operating System, or Nachos, is instructional software for teaching undergraduate, and potentially graduate level operating systems courses. It was developed at the University of California, Berkeley, designed by Thomas Anderson, and is used by numerous schools.Originally written in C++ for MIPS, Nachos runs as a user-process on a host operating system. A MIPS simulator executed the code for any user programs running on top of the Nachos operating system. Ports of the Nachos code exist for a variety of architectures.In addition to the Nachos code, a number of assignments are provided with the Nachos system. The goal of Nachos is to introduce students to concepts in operating system design and implementation by requiring them to implement significant pieces of functionality within the Nachos system.
