The AT&T Hobbit is a microprocessor design that AT&T Corporation developed in the early 1990s. It was based on the company's CRISP (C-language Reduced Instruction Set Processor) design, which in turn grew out of Bell Labs' C Machine design of the late 1980s. C Machine, CRISP and Hobbit were optimized for running the C programming language. The design concentrated on fast instruction decoding, indexed array access and procedure calls. Its processor was partially RISC-like. The project ended in 1994 because the Hobbit failed to achieve commercially viable sales.

Project Longshot was a conceptual interstellar spacecraft design. It would have been an unmanned probe, intended to fly to and enter orbit around Alpha Centauri B powered by nuclear pulse propulsion.

🔗 Intel

Intel's Skulltrail is an enthusiast gaming platform that was released on February 19, 2008. It is based on the company's 5400 "Seaburg" workstation chipset. The primary difference between Skulltrail and Intel's current and past enthusiast chipsets is a dual CPU socket design that allows two processors to operate on the same motherboard. Therefore, Skulltrail can operate eight processing cores on one system. The platform supports two Core 2 Extreme QX9775 processors (commonly mistaken for the Core 2 Extreme QX9770, which is the LGA775 counterpart), which operate at 3.2 GHz.

Skulltrail was one of the first platforms to support SLI on chipsets not designed by Nvidia. It achieves this by including two NVIDIA nForce 100 PCIe 1.1 switch (two x16 to one x16) chips. The implementation of SLI supports Quad SLI technology, which is achieved through the use of two dual-GPU graphics cards from NVIDIA, including the GeForce 9800 GX2. This gives a total of four graphics processors. Owners of Skulltrail systems can also make use of up to four ATI graphics cards using ATI CrossFireX technology, which made SkullTrail the only platform (other than Intel X58 and P55 Chipset) to support both SLI and CrossFire with public drivers at the time of release. The HP Firebird 803 also supported SLI on one (proprietary, MXM) motherboard at the time, but the drivers were special and only available for Firebird hardware.

The Inca road system (often spelled Inka road system and known as Qhapaq Ñan meaning "royal road" in Quechua) was the most extensive and advanced transportation system in pre-Columbian South America. It was at least 40,000 kilometres (25,000 mi) long. The construction of the roads required a large expenditure of time and effort.

The network was composed of formal roads carefully planned, engineered, built, marked and maintained; paved where necessary, with stairways to gain elevation, bridges and accessory constructions such as retaining walls, and water drainage system. It was based on two north-south roads: one along the coast and the second and most important inland and up the mountains, both with numerous branches. It can be directly compared with the road network built during the Roman Empire, although the Inka road system was built one thousand years later. The road system allowed for the transfer of information, goods, soldiers and persons, without the use of wheels, within the Tawantinsuyu or Inka Empire throughout a territory with an extension was almost 2,000,000 km² (770,000 sq mi) and inhabited by about 12 million people.

The roads were bordered, at intervals, with buildings to allow the most effective usage: at short distance there were relay stations for chasquis, the running messengers; at a one-day walking interval tambos allowed support to the road users and the flocks of carrying llamas. Administrative centers with warehouses for re-distribution of goods were found along the roads. Towards the boundaries of the Inka Empire and in new conquered areas pukaras (fortresses) were found.

Part of the road network was built by cultures that precede the Inka Empire, notably the Wari culture in the northern central Peru and the Tiwanaku culture in Bolivia. Different organizations such as UNESCO and IUCN have been working to protect the network in collaboration with the governments and communities of the six countries (Colombia, Ecuador, Peru, Bolivia, Chile and Argentina) through which the Great Inka Road passes.

In modern times the roads see heavy use from tourism, such as the Inca Trail to Machu Picchu, well known by trekkers, connecting Ollantaytambo with Machu Picchu.

🔗 Computer science

In computing, aspect-oriented programming (AOP) is a programming paradigm that aims to increase modularity by allowing the separation of cross-cutting concerns. It does so by adding behavior to existing code (an advice) without modifying the code itself, instead separately specifying which code is modified via a "pointcut" specification, such as "log all function calls when the function's name begins with 'set'". This allows behaviors that are not central to the business logic (such as logging) to be added to a program without cluttering the code core to the functionality.

AOP includes programming methods and tools that support the modularization of concerns at the level of the source code, while aspect-oriented software development refers to a whole engineering discipline.

Aspect-oriented programming entails breaking down program logic into distinct parts (so-called concerns, cohesive areas of functionality). Nearly all programming paradigms support some level of grouping and encapsulation of concerns into separate, independent entities by providing abstractions (e.g., functions, procedures, modules, classes, methods) that can be used for implementing, abstracting and composing these concerns. Some concerns "cut across" multiple abstractions in a program, and defy these forms of implementation. These concerns are called cross-cutting concerns or horizontal concerns.

Logging exemplifies a crosscutting concern because a logging strategy necessarily affects every logged part of the system. Logging thereby crosscuts all logged classes and methods.

All AOP implementations have some crosscutting expressions that encapsulate each concern in one place. The difference between implementations lies in the power, safety, and usability of the constructs provided. For example, interceptors that specify the methods to express a limited form of crosscutting, without much support for type-safety or debugging. AspectJ has a number of such expressions and encapsulates them in a special class, an aspect. For example, an aspect can alter the behavior of the base code (the non-aspect part of a program) by applying advice (additional behavior) at various join points (points in a program) specified in a quantification or query called a pointcut (that detects whether a given join point matches). An aspect can also make binary-compatible structural changes to other classes, like adding members or parents.

The eight-circuit model of consciousness is a hypothesis by Timothy Leary, and later expanded on by Robert Anton Wilson and Antero Alli, that "suggested eight periods [circuits] and twenty-four stages of neurological evolution". The eight circuits, or eight "brains" as referred by other authors, operate within the human nervous system, each corresponding to its own imprint and direct experience of reality. Leary and Alli include three stages for each circuit that details developmental points for each level of consciousness.

The first four circuits deal with life on Earth, and survival of the species. The last four circuits are post-terrestrial, and deal with the evolution of the species, altered states of consciousness, enlightenment, mystical experiences, psychedelic states of mind, and psychic abilities. The proposal suggests that these altered states of consciousness are recently realized, but not widely utilized. Leary describes the first four as "larval circuits", necessary for surviving and functioning in a terrestrial human society, and proposed that the post terrestrial circuits will be useful for future humans who, through a predetermined script, continue to act on their urge to migrate to outer space and live extra-terrestrially. Leary, Wilson, and Alli have written about the idea in depth, and have explored and attempted to define how each circuit operates, both in the lives of individual people and in societies and civilization.

The term "circuit" is equated to a metaphor of the brain being computer hardware, and the wiring of the brain as circuitry.

Leary uses the eight circuits along with recapitulation theory to explain the evolution of the human species, the personal development of an individual, and the biological evolution of all life.

🔗 Radio Stations

United Biscuits Network (UBN) was an internal radio station serving the factories of United Biscuits (UB) in Britain that operated from 1970 to 1979.

In 1970 the BBC had a monopoly on radio broadcasting in Britain, although there were a few offshore pirate radio broadcasters, such as Radio Caroline. At one time factories had sought to avoid unnecessary background sound, but during the Second World War psychologists found that light background music (muzak) increased productivity at times it was low, a trend that continued after the war. But as jobs became deskilled and ever more monotonous, muzak became less effective, and staff turnover increased. United Biscuits was affected by this trend; Hector Laing, the managing director in the 1960s, needed to reduce the costs of high staff turnover. Inspired by the success of the pirate stations, Laing hired suitable staff, bought state-of-the-art broadcasting equipment, and set up UBN at UB headquarters in Osterley, west London (later the headquarters of broadcaster Sky UK).

The Art of Being Right: 38 Ways to Win an Argument (also The Art of Controversy, or Eristic Dialectic: The Art of Winning an Argument; German: Eristische Dialektik: Die Kunst, Recht zu behalten; 1831) is an acidulous, sarcastic treatise written by the German philosopher Arthur Schopenhauer. In it, Schopenhauer examines a total of thirty-eight methods of showing up one's opponent in a debate. He introduces his essay with the idea that philosophers have concentrated in ample measure on the rules of logic, but have not (especially since the time of Immanuel Kant) engaged with the darker art of the dialectic, of controversy. Whereas the purpose of logic is classically said to be a method of arriving at the truth, dialectic, says Schopenhauer, "...on the other hand, would treat of the intercourse between two rational beings who, because they are rational, ought to think in common, but who, as soon as they cease to agree like two clocks keeping exactly the same time, create a disputation, or intellectual contest."

CleanFlicks was a company founded in Utah in 2000 that rented and sold commercially-released DVDs and VHS tapes from which they had edited content which the company considered inappropriate for children or that viewers might otherwise find offensive. CleanFlicks removed sexual content, profanity, some references to deity, and some violence from movies, either by muting audio or clipping entire portions of the track.

A group of major film productions studios sued CleanFlicks in 2002, arguing that their service constituted copyright infringement. A 2006 court ruling closed the company. On March 13, 2007, CleanFlicks reopened its website with "Movies You Can Trust." While legally enjoined from offering edited movies, an email sent by the company on that date indicated that they had reviewed "tens of thousands" of movies and compiled over 1000 that meet their "family-friendly criteria" for sale and rent. In January 2013, the CleanFlicks.com website was no longer online.
