Cascading Style Sheets

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language. Although most often used to set the visual style of web pages and user interfaces written in HTML and XHTML, the language can be applied to any XML document, including plain XML, SVG and XUL, and is applicable to rendering in speech, or on other media. Along with HTML and JavaScript, CSS is a cornerstone technology used by most websites to create visually engaging webpages, user interfaces for web applications, and user interfaces for many mobile applications.

CSS is designed primarily to enable the separation of document content from document presentation, including aspects such as the layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple HTML pages to share formatting by specifying the relevant CSS in a separate .css file, and reduce complexity and repetition in the structural content, such as semantically insignificant tables that were widely used to format pages before consistent CSS rendering was available in all major browsers. CSS makes it possible to separate presentation instructions from the HTML content in a separate file or style section of the HTML file. For each matching HTML element, it provides a list of formatting instructions. For example, a CSS rule might specify that "all heading 1 elements should be bold", leaving pure semantic HTML markup that asserts "this text is a level 1 heading" without formatting code such as a <bold> tag indicating how such text should be displayed.

Polikarpov Po-2

The Polikarpov Po-2 (also U-2) served as a general-purpose Soviet biplane, nicknamed Kukuruznik (Russian: Кукурузник, from Russian "kukuruza" (кукуруза) for maize; thus, "maize duster" or "crop duster"), NATO reporting name "Mule". The reliable, uncomplicated concept of the Po-2's design made it an ideal training aircraft, as well as doubling as a low-cost ground attack, aerial reconnaissance, psychological warfare and liaison aircraft during war, proved to be one of the most versatile light combat types to be built in the Soviet Union. As of 1978 it remained in production for a longer period of time than any other Soviet-era aircraft.

It is one of the most produced aircraft, and may be the most produced biplane with production possibly as high as 30,000 Po-2s built between 1928 and 1959. However, production figures for Polikarpov U-2 and Po-2 bombers and trainers combined are between 20,000 and 30,000. with production ending as early as 1952. Correct figures are hard to come by since low-rate production by small repair shops and air clubs likely continued until 1959.

Photographic developer

In the processing of photographic films, plates or papers, the photographic developer (or just developer) is one or more chemicals that convert the latent image to a visible image. Developing agents achieve this conversion by reducing the silver halides, which are pale-colored, into silver metal, which is black (when a fine particle). The conversion occurs within the gelatine matrix. The special feature of photography is that the developer only acts on those particles of silver halides that have been exposed to light. Generally, the longer a developer is allowed to work, the darker the image.

Chemical composition of developers

For black-and-white photography, the developer typically consists of a mixture of chemical compounds prepared as an aqueous solution. Three main components of this mixture are:

Software developer

A software developer is a person concerned with facets of the software development process, including the research, design, programming, and testing of computer software. Some notable software developers include Peter Norton (developer of Norton Utilities), Richard Garriott (Ultima-series creator), and Philippe Kahn (Borland key founder), all of whom started as entrepreneurial individuals or small-team software developers.

Other names which are often used in the same close context are programmer, software analyst, and software engineer. According to developer Eric Sink, the differences between system design, software development and programming are more apparent. Already in the current market place there can be found a segregation between programmers and developers, being that one who implements is not the same as the one who designs the class structure or hierarchy. Even more so that developers become systems architects, those who design the multi-leveled architecture or component interactions of a large software system.
