Software development activities

The most important task in creating a software product is extracting the requirements or requirements analysis. Customers typically have an abstract idea of what they want as an end result, but not what software should do. Incomplete, ambiguous, or even contradictory requirements are recognized by skilled and experienced software engineers at this point. Frequently demonstrating live code may help reduce the risk that the requirements are incorrect.

Once the general requirements are gleaned from the client, an analysis of the scope of the development should be determined and clearly stated. This is often called a scope document. Certain functionality may be out of scope of the project as a function of cost or as a result of unclear requirements at the start of development. If the development is done externally, this document can be considered a legal document so that if there are ever disputes, any ambiguity of what was promised to the client can be clarified.

Software development process

A software development process is a structure imposed on the development of a software product. Synonyms include software life cycle and software process. There are several models for such processes, each describing approaches to a variety of tasks or activities that take place during the process.

A largely growing body of software development organizations implements process methodologies. Many of them are in the defense industry, which in the U.S. requires a rating based on 'process models' to obtain contracts.

The international standard for describing the method of selecting, implementing and monitoring the life cycle for software is ISO 12207.

Software Developer

A software developer is a person or organization concerned with the facts of the software development process wider than design and coding, a somewhat broader scope of computer programming or a specialty of project managing including some aspects of software product management. This person may contribute to the overview of the project on the application level rather than component level or individual programming tasks. Software developers are often still guided by lead programmers but also encompass the class of freelance software developers.

Other names which are often used in the same close context are software analyst and software engineer.

Web design

Web page design is a process of conceptualization, planning, modeling, and execution of electronic media content delivery via Internet in the form of technologies (such as markup languages) suitable for interpretation and display by a web browser or other web-based graphical user interfaces (GUIs).

The intent of web design is to create a web site (a collection of electronic files residing on one or more web servers) that presents content (including interactive features or interfaces) to the end user in the form of web pages once requested. Such elements as text, forms, and bit-mapped images (GIFs, JPEGs, PNGs) can be placed on the page using HTML, XHTML, or XML tags. Displaying more complex media (vector graphics, animations, videos, sounds) usually requires plug-ins such as Flash, QuickTime, Java run-time environment, etc. Plug-ins are also embedded into web pages by using HTML or XHTML tags.

Improvements in the various browsers' compliance with W3C standards prompted a widespread acceptance of XHTML and XML in conjunction with Cascading Style Sheets (CSS) to position and manipulate web page elements. The latest standards and proposals aim at leading to the various browsers' ability to deliver a wide variety of media and accessibility options to the client possibly without employing plug-ins.

Steroids

You may have heard about anabolic steroids, which can have harmful effects. But there's another type of steroid - sometimes called a corticosteroid - that treats a variety of problems. These steroids are similar to hormones that your adrenal glands produce to fight stress associated with illnesses and injuries. They reduce inflammation and affect the immune system.
You may need to take corticosteroids to treat
* Arthritis
* Asthma
* Autoimmune diseases such as lupus and multiple sclerosis
* Skin conditions such as eczema and rashes
* Some kinds of cancer
Steroids are strong medicines, and they can have side effects, including weakened bones and cataracts. Because of this, you usually take them for as short a period as possible.

A Snapshot of Macro-Economics

Economics is the learning of making choices. High school and college students all over required to take economic courses in order to achieve a diploma. Why is economics so important because it provides a guide for students for real-world situations. Economics is divided into two types microeconomics and macroeconomics. Microeconomics is the study of economics at a slim level. For example absorbed on how a detailed business functions is microeconomics.
Studying the world economy is classified as Macroeconomics; its center on a much broader level. All students must understand the concept of insufficiency. Scarcity is a condition that occurs because society has unlimited wants and needs however the amount of property is limited. Unlimited wants and needs are what encourage us to create goods and services. We are never satisfied therefore we always have a want or need. On the other hand our income is limited.

Server-side scripting

Server-side scripting is a web server knowledge in which a user's request is fulfilled by organization a script directly on the web server to make dynamic HTML pages. It is typically used to provide interactive web sites, that border to databases or other data food. This is different from client-side scripting where scripts are run by the presentation web browser, usually in JavaScript. The primary benefit to server-side scripting is the aptitude to highly customize the response based on the user's supplies, access rights, or queries into data stores.

When the server serves data in a usually used manner, for example according to the HTTP or FTP protocols, users may have their option of a number of client programs. In the case of more specialized application, programmers may write their own server, client, and infrastructure protocol, that can only be used with one one more.

Markup language

A markup language is an artificial language using a set of comments to text that give commands concerning the structure of text or how it is to be displayed. Markup languages have been in use for centuries, and in fresh years have also been used in computer typesetting and word-processing systems.

A well-known example of a markup language in use today in calculate is HyperText Markup Language, one of the the majority used in the World Wide Web. HTML follows some of the markup convention used in the publish industry in the message of printed work amongst authors, editors, and printers.

Client-side scripting

Client-side scripting generally refers to the class of computer programs on the web that are execute client-side, by the user's web browser, instead of server-side. This type of computer programming is an significant part of the Dynamic HTML concept, enabling web pages to be scripted; that is, to have different and changing content depending on user input, environmental conditions, or other variables.

Web author write client-side script in languages such as JavaScript and VBScript.

Client-side scripts are often embedded within an HTML text, but they may also be enclosed in a separate file, which is referenced by the document that uses it. Upon request, the necessary files are sending to the user's computer by the web server on which they reside. The user's web browser executes the script, and then displays the document, including any visible production from the script. Client-side scripts may also contain orders for the browser to follow if the user interacts with the text in a certain way, e.g., clicks a certain button. These instructions can be followed without further message with the server, though they may require such message.

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.

Hodgkin's Disease

Hodgkin's disease is a kind of lymphoma. Lymphoma is growth of lymph tissue establish in the lymph nodes, spleen, liver, and bone core. The first sign of Hodgkin's illness is often a distended lymph node. The disease can increase to nearby lymph nodes. Later it may increase to the lungs, liver or bone marrow. The cause is indefinite.

Hodgkin's illness is rare. Symptoms take in

* painless bulge of the lymph nodes in the neck, armpits, or groin
* fever and chills
* night sweats
* weight loss
* loss of appetite
* itchy skin

Doctors can diagnose Hodgkin's illness with a biopsy. This involves remove and investigative a piece of tissue under a microscope. Treatment varies depending on how far the disease has increase and often includes emission therapy or chemotherapy. The earlier the illness is diagnosed, the more effectual the treatment. In most cases, Hodgkin's disease can be cure.

Bone Marrow Diseases

Bone marrow is the spongy tissue within some of your bones, such as your hip and thigh bones. It contains young cells, called stem cells. The stanch cells can expand into the red blood cells that carry oxygen from side to side your body, the white blood cells that scrap infections, and the platelets that assist with blood clotting.

If you have a bone marrow illness, there are harms with the stem cells or how they expand. Leukemia is a cancer in which the bone marrow produces abnormal white blood cells. With aplastic anemia, the bone marrow doesn't make red blood cells. Other diseases, such as lymphoma, can increase into the bone marrow and distress the creation of blood cells. Other causes of bone essence disorders include your genetic makeup and ecological factors.

Symptoms of bone marrow disease vary. Treatments depend on the disorder and how harsh it is. They might engage medicines, blood transfusions or a bone marrow remove.

Child Abuse

Child abuse is doing incredible or fault to do something that consequence in harm to a child or puts a child at risk of harm. Child violence can be physical, sexual or emotional. Neglect, or not providing for a child's needs, is also an outline of abuse.

Most abused children endure greater emotional than physical damage. An abused child may become dejected. He or she may leave, think of suicide or become violent. An older child may use drugs or alcohol, try to run left or abuse others.

Child abuse is a serious trouble. If you think a child is being abused or neglected, call the police or your local child safety agency.
