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.
.web is a generic top-level domain that will be awarded by ICANN to one of seven registry applicants. The .web TLD will be in the official root once ICANN awards the registry contract.
Historic information about .web
.web was operated as a prospective registry, not in the official root, by Image Online Design since 1995. It originated when Jon Postel, then running the top level of the Domain Name System basically single-handedly, proposed the addition of new top-level domains to be run by different registries. Since Internet tradition at the time emphasized "rough consensus and running code", Christopher Ambler, who ran Image Online Design, saw this as meaning that his company could get a new TLD into the root by starting up a functional registry for it. After asking and receiving permission from IANA to do so, IOD launched .web, a new unrestricted top level domain.
Since then IOD has tried to get their domain into the official root through several plans to admit new top-level domains. Several new-TLD plans in the late 1990s, including Postel's original proposal, failed to reach sufficient consensus among the increasingly contentious factions of the Internet to admit any new TLDs, including .web. When ICANN accepted applications for new TLDs in 2000 which resulted in the seven new domains added soon afterward, IOD's application was not approved; neither was it officially rejected, however, since all unapproved applications remain in play for possible future acceptance. A second round of new TLDs, however, was done entirely with new applications, and only for sponsored domains (generally intended for use by limited communities and run by nonprofit entities). The .web registry remains hopeful, however, that their application will eventually be approved. On May 10, 2007, ICANN announced the opening of public comments towards a new, third round of new gTLDs, a round in which IOD has not participated.
Since vector fields can be visualized as stream-lines of a stationary flow or as Faraday’s lines of force, a non-vanishing vector field in space generates a space-filling system of lines through each point, known to mathematicians as a congruence (i.e., a local foliation). Ricci’s vision filled Riemann’s n-dimensional manifold with n congruences orthogonal to each other, i.e., a local orthogonal grid.
