PowerHouse is a byte-compiled fourth-generation programming language (or 4GL) originally produced by Quasar Corporation (later renamed Cognos Incorporated) for the Hewlett-Packard HP3000 mini-computer, as well as Data General and DEC VAX/VMS systems. It was initially composed of five components:
Wallbox was founded in Barcelona, Spain by Enric Asunción and Eduard Castañeda in 2015 initially using the name Wall Box Chargers. In 2017, Wallbox came first in South Summit, a European startup competition. Wallbox then came in third place at the Startup World Cup in May 2018.
The object itself was detected in ESO images dating back to 1980, but its identification as a quasar occurred only several decades later. [2]An automated analysis of 2022 data from the European Space Agency's Gaia satellite did not confirm J0529-4351 as too bright to be a quasar, and suggested it was a 16th magnitude star with a 99.98% probability.
The Quasar Framework (commonly referred to as Quasar; pronounced / ˈ k w eɪ. z ɑːr / [4]) is an open-source Vue.js based framework for building apps with a single codebase. It can be deployed on the Web as a SPA, PWA, SSR, to a Mobile App, using Cordova for iOS & Android, and to a Desktop App, using Electron for Mac, Windows, and Linux.

At least three generations have been used: SDS-1 from 1976 to 1987; SDS-2 from 1989 to 1996; SDS-3 from 1998 to the present. It is believed that these satellites were known by the code name Quasar. [1] The first generation was named simply 'SDS', the second generation was named 'Quasar' and the third generation each had their own designations. [2]
The effect is sometimes called the "Doppler–Fizeau effect". In 1868, British astronomer William Huggins was the first to determine the velocity of a star moving away from the Earth by the method. [5] In 1871, optical redshift was confirmed when the phenomenon was observed in Fraunhofer lines, using solar rotation, about 0.1 Å in the red. [6]
Quasar Data Products Inc. (QDP), later QDP Computer Systems Inc., was an American computer company based in 1979 in North Olmsted, Ohio, United States. The company was founded by Brian A. Catalucci and Dave L. Kelley, the former a trained engineer who had previously worked as an airline pilot.
