Keynote (presentation software)

Keynote is a presentation software application developed as a part of the iWork productivity suite by Apple Inc. Keynote 6.0 was announced on October 23, 2013 and is the most recent version for the Mac. On January 27, 2010, Apple announced a new version of Keynote for iPad with an all new touch interface.

History

Keynote began as a computer program for Apple CEO Steve Jobs to use in creating the presentations for Macworld Conference and Expo and other Apple keynote events. Prior to using Keynote, Jobs had used Concurrence, from Lighthouse Design, a similar product which ran on the NeXTSTEP and OpenStep platforms.

The program was first sold publicly as Keynote 1.0 in 2003, competing against existing presentation software, most notably Microsoft PowerPoint.

In 2005 Apple began selling Keynote 2.0 in conjunction with Pages, a new word processing and page layout application, in a software package called iWork. At the Macworld Conference & Expo 2006, Apple released iWork '06 with updated versions of Keynote 3.0 and Pages 2.0. In addition to official HD compatibility, Keynote 3 added new features, including group scaling, 3D charts, multi-column text boxes, auto bullets in any text field, image adjustments, and free form masking tools. In addition, Keynote features three-dimensional transitions, such as a rotating cube or a simple flip of the slide.

Database index

A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Indexes can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records.

An index is a copy of select columns of data from a table that can be searched very efficiently that also includes a low-level disk block address or direct link to the complete row of data it was copied from. Some databases extend the power of indexing by letting developers create indices on functions or expressions. For example, an index could be created on upper(last_name), which would only store the upper case versions of the last_name field in the index. Another option sometimes supported is the use of partial indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.

Key (music)

In music theory, the key of a piece is the tonic note and chord that provides a subjective sense of arrival and rest. Other notes and chords in the piece create varying degrees of tension, resolved when the tonic note or chord returns. The key may be major or minor, although major is assumed in a phrase like "this piece is in C." Popular songs are usually in a key, and so is classical music during the common practice period, about 1650–1900. Longer pieces in the classical repertoire may have sections in contrasting keys.

Methods that establish the key for a particular piece can be complicated to explain, and vary over music history. However, the chords most often used in a piece in a particular key are those that contain the notes in the corresponding scale, and conventional progressions of these chords, particularly cadences, orient the listener around the tonic.

The key signature is not a reliable guide to the key of a written piece. It does not discriminate between a major key and its relative minor; the piece may modulate to a different key; if the modulation is brief, it may not involve a change of key signature, being indicated instead with accidentals. Occasionally, a piece in a mode such as Mixolydian or Dorian is written with a major or minor key signature appropriate to the tonic, and accidentals throughout the piece.

Bossé

Bossé can be:

Turbomasters

Turbomasters were an Australian, Canadian, and European exclusive range of Transformers toys, released in 1992 as part of their final year of products for the original franchise. A subgroup of the Autobots, there were six Turbomasters: Thunder Clash, Rotorstorm, Boss, Hurricane, Flash, and Scorch. They all had the gimmick of missile launchers which became their engines or turbines when in vehicle mode. Their rivals were the Decepticon Predators. A seventh Turbomaster called Hyperdrive was designed but never released.

Members

Thunder Clash - Function: Commander-in-chief. Thunder Clash is the leader of the Turbomasters and commands the respect of the Autobots, and the loathing of the Predators. He possesses a sharp and keen strategic mind, able to counter the abilities the Predators possess. Thunder Clash transforms into a Cybertronian truck cab with an accompanying trailer, which transforms into a command center.

Rotorstorm - Function: Guide and strategician. The only airborne member of the Turbomasters, Rotorstorm transforms into a helicopter. Possesses a "dodge" ability that allows him to guide his grounded comrades. He maintains an image that he is a ruthless and fearless fighter, respected by all, even the Decepticons, so that he can inspire and motivate his comrades.

Boss (Australian band)

Boss were a hard rock-heavy metal band from Sydney, Australia.

History

Craig Csongrady (vocals) originally formed Boss in Adelaide, Australia, during 1979. Kevin Pratt (guitar) and Csongrady moved in 1980 to Sydney, where Dapto, Wollongong guitarist Peter Sutcliffe was added to the line-up. Boss commenced a heavy schedule of live performances on the Sydney pub and club circuit. Most notably, some of the band's best performances were at the Astra Hotel Bondi. In 1983, Boss released a two-track self-titled single, produced by Jon Kennett.

The band had a very short-lived career that was at its peak in 1984 with the international release of the LP Step On It. The LP was well received in Europe, but failed to achieve the same success locally, and the band fell apart soon after. Many fans were disappointed to learn that a Roland TR-909 drum machine was used instead of a real drummer on the Step On It LP. The success of Step On It also saw Boss support a number of bigger acts including Iron Maiden, Twisted Sister, and Ronnie James Dio.
