At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO2); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.
By 1976, Aerosmith had recorded three albums: Aerosmith (1973), Get Your Wings (1974), and the breakthrough LP Toys in the Attic (1975), which produced the Top Ten hit "Walk This Way" and the popular "Sweet Emotion." Although often derided by critics, the band had amassed a loyal fan following from relentless touring and their ferocious live shows. They also began living the rock and roll lifestyle to the hilt, indulging their already considerable appetite for drugs. However, their hedonistic lifestyle did not appear to hamper them creatively; Rocks is considered by many fans, critics, and fellow musicians to be one of the highlights of their career. Guitarist Joe Perry later recalled, "There's no doubt we were doing a lot of drugs by then, but whatever we were doing, it was still working for us."
However the Rocks Framework also includes other functionality such as a templated system for producing web pages, which encaspulates general web development problems.
This is an open source project hosted on SourceForge the development team mainly consists of volunteers. Currently this framework is in alpha testing.
This is similar to the active record pattern with one class corresponding to one table in the database however it is slightly different in that each class maps dynamically to the table.
Although as of version 0.02 multiple classes can now be returned using the RocksDBOArray class.
This selects a user with the username value of John. Smith if more than one record is returned an exception will be thrown. A record can be saved like so:
Due to the dynamic nature of Rocks you can specify as many fields as you like in a class. For instance in the example above a field called age could also be provided but unless there is a corresponding field in the database table this will not be saved or updated from data in the database.
Although the Internet protocol suite has been used by academia and the military industrial complex since the early 1980s, rapid adoption of its use was driven by events of the late 1980s and 1990s such as more powerful and affordable computers, the advent of fiber optics, the popularization of HTTP and the Web browser, and a push towards opening the technology to commerce. Internet use grew rapidly in the West from the mid-1990s and from the late 1990s in the developing world. In the 20 years since 1995, Internet use has grown 100-times to reach over one third of the world population, leading to its services and technologies being incorporated into virtually every aspect of contemporary life. The impact of the Internet has been so immense that it has been referred to as the "8th continent".
