In the perfect case the crossfader would keep constant output level. However, there's no standard how this should be achieved. Many DJ equipment manufacturers offer different mixers for different purposes (e.g. scratching, beatmixing, cut mixing, etc.). High-end mixers often have crossfade curve switches allowing the DJ to select the type of crossfade necessary. Experienced DJs are also able to crossfade between tracks using the channel faders.
There are many software applications that feature virtual crossfaders. For instance, burning-software for the recording of audio-CDs.
On a mixer with auxiliary send mixes, the send mixes are configured pre-fader or post-fader.
If a send mix is configured pre-fader, then changes to the main channel strip fader does not affect the send mix. This is useful for stage monitor mixes where changes in the Front of House channel levels would distract the musicians.
If a send mix is configured post-fader, then the level sent to the send mix follows changes to the main channel strip fader. This is useful for reverberation and other signal processor effects.
Centenary Medal
The Centenary Medal is an award given by the Australian Government in 2001. It was set up to celebrate the Centenary of Federation of Australia and to honour people who have made a contribution to Australian society or government. Possible winners were studied by a group headed by the historian Professor Geoffrey Blainey.
The front of the medal has a seven-pointed Commonwealth Star, for the six Australian states, with the seventh point for Australia's territories. At the centre of the star is an image showing the Indigenous Australian traditions at the heart of the continent. Around the edge are 100 dots for 100 years of federation. The other side has a seven pointed star, with the words "For Contribution Made to Australian Society" around the edge.
The colours in the ribbon are crimson, which represents federation, and blue and gold for the beginning of the 21st Century. The seven gold and red lines signify the states' pathways to federation. The bar and ribbon are the same so that a person with the award can be recognized easily.
Backspace
Backspace is the keyboard key (sometimes labeled as: ← ) that originally pushed the typewriter carriage one position backwards, and for modern computer screens, moves the cursor one position backwards, deletes the preceding character, and shifts back the text after it by one position.
In typewriters, a typist would, for example, type a lowercase letter "a" with acute accent (á) by typing a lowercase letter "a" then backspace, and then the acute accent key (also known as overstrike). This is the basis for such spacing modifiers in computer character sets such as the ASCII caret (^, for the circumflex accent). Backspace composition no longer works with digital displays or typesetting systems. It has to some degree been replaced with the combining diacritical marks mechanism of Unicode, though such characters do not work well with many fonts, and precomposed characters continue to be used. Some software like TeX or Microsoft Windows use the opposite method for diacritical marks, namely positioning the accent first, and then placing the base letter at that position.
Pressing the backspace key on a computer terminal would generate the ASCII code 08, BS or Backspace, a control code which would delete the preceding character. That control code could also be accessed by pressing Control-H, as H is the eighth letter of the Latin alphabet. Terminals which did not have the backspace code mapped to the function of moving the cursor backwards and deleting the preceding character would display the symbols ^H (caret, H – see Caret notation) when the backspace key was pressed. This sequence is still used humorously for epanorthosis by computer literates, denoting the deletion of a pretended blunder, much like a strikethrough.
Example:
A more concise alternative sometimes seen is ^W, which is the shortcut to delete the previous word in the Berkeley Unix terminal line discipline. One ^W can replace a whole string of ^H's. This shortcut has also made it into the Vi text editor. For really embarrassing blunders, ^U (kill line) can outdo a series of ^W.
The backspace is distinct from the delete key, which in paper media for computers would punch out all the holes to strike out a character, and in modern computers deletes text "following" it. Also, the delete key often works as a generic command to remove an object (such as an image inside a document, or a file in a file manager), while backspace usually has no effect.
In modern systems, the backspace key is often mapped to the delete character (0x7f in ASCII or Unicode), although the backspace key's function of deleting the character before the cursor remains.
In a mainframe environment, "to backspace" means to move a magnetic tape backwards, typically to the previous block.
The backspace key is commonly used to go back a page when exploring folders in graphical environments, or when browsing the Web in web browsers.
Although the term "backspace" is the standard name of the key which deletes the character to the left of the cursor, the actual key may be labelled in a variety of ways, for example "delete", "Erase" (for example in XO-1, One Laptop Per Child), or with a left pointing arrow.
Australian Sports Medal
The Australian Sports Medal was an award given during 2000 to recognise achievements in Australian sport.
Winners of the award included competitors, coaches, sports scientists, office holders, and people who maintained sporting facilities and services. Over 18,000 Medals were awarded.
Marin Mersenne
Marin Mersenne, (born 8 September 1588, in modern-day Sarthe, died 1 September 1648, in Paris) was a French theologian and mathematician. He developed the first laws of acoustics, which was known by his name for a long time. Today, he is mainly remembered for the Mersenne primes. Together with Galileo Galilei he built the laws which describe how a mass falls in an empty space. He was in favour of modern science, and did not agree with "occultist" movements.
He often travelled to meet great scientists, which made him an important mediator. This is especially true for mathematicians such as Pierre Gassendi, Gilles Personne de Roberval, Blaise Pascal und Pierre de Fermat. To tell Mersenne of a discovery was like publishing it. He told Gassendi to reply to the "Meditations" of Descartes. Mersenne gave Huygens the idea of using a pendulum to measure time. This led to the development of pendulum clocks.
Land Transport Authority
The Land Transport Authority (Abbreviation: LTA; Chinese: 陆路交通管理局 (shortform: 陆交局); Malay: Penguasa Pengangkutan Darat; ) of Singapore is a statutory board of the Ministry of Transport. It was founded in 1 September 1995, by merging four agencies, which are Registry of Vehicles, Mass Rapid Transit Corporation, Roads & Transportation Division of the Public Works Department of Singapore and Land Transport Division of the then-Ministry of Communications. LTA leads the development of land transport in Singapore.
Usage share of web browsers
The usage share of web browsers
is the percentage (%) of viewers at a group of websites who use a particular web browser. For example, when it is said that Internet Explorer has 7% usage share (April 2018), it means that some version of Internet Explorer is used by nearly 7 of every 100 visitors who visit a given set of websites.
It can be misleading to measure the browser usage in the number of requests (page hits) made by each user agent.
Not all requests are generated by a user, as a user agent can make requests at regular time intervals without user input. In this case the user's activity might be overestimated. Some examples:
It is also possible to underestimate the usage share by using the number of requests, for example:
The following table summarizes the usage share of browsers for all platforms.
