8th millennium

The eighth millennium of the Gregorian calendar will begin on January 1, 7001, and end on December 31, 8000. It will be the eighth millennium in the Anno Domini or Common Era.

Astronomical events

All these dates are in a uniform time scale such as Terrestrial Time. When converted to our ordinary solar time or Universal Time, which is decidedly non-uniform, via ΔT, the dates would be about one day earlier.

USB

USB, short for Universal Serial Bus, is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. It is currently developed by the USB Implementers Forum.

USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.

Overview

In general, there are three basic kinds or sizes related to the USB connectors and types of established connection: the older "standard" size, in its USB 1.1, 2.0, and 3.0 variants (for example, on USB flash drives), the "mini" size (primarily for the B connector end, such as on many cameras), and the "micro" size, in its USB 1.1, 2.0, and 3.0 variants (for example, on most modern mobile phones).

Amateur radio

Amateur radio (also called ham radio) describes the use of radio frequency spectra for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the International Telecommunication Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics and the host government's radio regulations. Radio amateurs use a variety of voice, text, image, and data communications modes and have access to frequency allocations throughout the RF spectrum to enable communication across a city, region, country, continent, the world, or even into space.

Radio software

Almost all radio stations today use some form of broadcast automation. Although some only use small scripts in audio players, a more robust solution is using a full Radio Automation Suite. There are many commercial and free radio automation packages available.

Radio software history

Radio software allows AM & FM broadcasting to reproduce music and voices from the computer’s hard disk instead of using CD, tape recorders or the old cartridge tape (see Fidelipac). Usually the radio stations stores all advertising campaigns and most of the music in hard disk. Then, instant replay of all the recorded material is done from a keyboard or with a click of the mouse. Now the PC is part of every AM & FM broadcasting, webcasting or podcasting system around the world.

Radio software not only reproduces audio. It is possible to create a “playlist” that can reproduce automatically, without a board operator, a complete radio program, including meteorological announces, advertising campaigns, music tunes, satellite network connection, etc. Then, 24 hours radio stations are possible, also in small towns that can not afford to have operators and speakers all around the clock. Standard PCs are connected in a LAN network to be used on the Master Control Room, Production, News, Administration, etc.
