Standards in web development

The W3C maintains a set of open values and guidelines which are generally measured best practices to follow when indoctrination for the web. Often, web developers help contribute to these open principles and guidelines through their work on open source projects operational to help enhance and debug web-based technology.

However, because of the fairly low barrier to entry liberally available development environment, freely available tutorials and in sequence on how to do web development novice web developers often do not adhere to the open standards and strategy. Additionally, poorly intended or proprietary software tools that don't follow the open standards and strategy create ad hoc and de facto principles which must be followed in order to "make things work". This was principally true during the "Browser Wars" of the 1990s. It is becoming less true as more and better tools enter the market.

Web developer

A web developer is a software developer or software engineer who is purposely engaged in the development of World Wide Web application, or scattered network applications that are run over the HTTP protocol from a web server to a web browser. Many web developers are also expert in related areas such as web design, in order architecture, usability engineering, web content organization systems, web server management, database administration, software engineering, project management, network security, and search engine optimization.

Developers often concentrate in either frontend or backend work. Frontend developers tend to focus on the client-side and typically work with technology such as markup languages, ECMAscript and its variants, CSS, and the DOM. Backend developers typically focus on the interaction among server-side frameworks using Perl, Python, Ruby, PHP, JSP, or .NET and databases. Some backend developers maintain database directly on their web servers, while in other situation the backend developer calls data, managed by a record administrator, on an external system.

In recent years the role of Presentation Layer Developer has evolve from the Frontend Technologist/Interface Developer role. Those previous roles specially focused on implementing browser/client side technology such as HTML, CSS and JavaScript. As web architecture has become more complex there has been an augmented need for deeper integration with the application server.

Some, but not all, web developers create graphics, logos, or identity, or create written, video, or audio content for a website. However, in many organization these duties are not the liability of web developers, but instead are handle by web designers or web producers.

Minerals

Minerals are imperative for your body to stay strong. Your body uses minerals for many diverse jobs, including structure bones, making hormones and adaptable your heartbeat.

There are two kinds of mineral deposits: macrominerals and trace minerals. Macrominerals are minerals your body requirements in larger amounts. They comprise calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. Your body wants just small amounts of trace natural resources. These include iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium.

The best way to get the raw materials your body needs is by eating a wide diversity of foods. In some cases, your doctor may advocate a mineral addition.
