Scheme Programming Language - 1,539 words
Each programming language presents a particular world view in the features it allows, supports, and forbids. This series of articles describes the world view of the Scheme Programming Language. This view contains many elements desired in a modern programming language: multi-paradigm support, composable, reusable abstractions, ability to create languages specialized for particular applications, clean separation of the generic and the implementation specific, and scalability from stand alone utilities to major software systems. Scheme started as an experiment in programming language design by challanging some fundamental design assumptions. It is currently gaining favor as a first programming ...

... n slowly or are not very space efficient and then reliably transformed into programs which are smaller and run much faster--and are also correct. Code transformations become second nature to experienced Scheme programmers. When a function similar to the recursive function fact is seen, it tends to get written down in the iterative form. Scheme has several important advantages. Its elegantly simple, regular structure and trivial syntax avoids "special case" confusion. Its expressiveness means that one spends little time trying to work around the language--it lets users concentrate on *what* they want to say rather than on *how* to say it. Its support of a variety of styles (including OO, ...

Stated differently, businesses must design the processes customers will use to conduct E-commerce transactions from a customer prospective. In other words, your business processes must support the customers needs, not merely your business needs. Many of the technologies noted above can provide customers with the ability to initiate and complete transactions on their own. They should be allowed to do so. When customers can complete most transactions using technology, midd ...

Although DOS had cornered the PC market, UNIX was still dominant on the larger workstations. The birth of UNIX in 1969 provided the world with its first modern operating system. An interactive multi-user operating system, UNIX was initially developed by programmers for their own use. Working for Bell Laboratories, Ken Thompson and Dennis Ritchie created UNIX as an operating system for the PDP-7 computer. Designed as a simplification of an operating system named Multics, UNIX was developed in Assembly language, a pri ...

Patented Algorithms - 949 words
Software consists of lists of instructions that a computer reads and executes. The tasks done by a computer are largely repetitive; the same chunks of instructions are executed many times. Each chunk performs one specific task and goes by the label algorithm, a method for accomplishing a specific task. In the United States, it is possible to obtain a patent for a software algorithm. One example of a patented software algorithm is the LZW software algorithm. The LZW patent is owned by Unisys. The algorithm is commonly used to compress an image file into a format know as the Graphics Interchange Format (gif). Patent law was created to protect the rights of the inventor and to encourage innovat ...

Many have heard of Java, yet few know what it is, or what it can do. It certainly has the potential to become a part of our everyday lives, existing in our mobile phones, televisions, and Internet browsers.

A high-level programming language developed by Dennis Ritchie at Bell Labs in the mid 1970s. Although originally designed as a systems programming language, C has proved to be a powerful and flexible language that can be used for a variety of applications, from business programs to engineering. C is a particularly popular language for personal computer programmers because it is relatively small -- it requires less memory than other languages. The first major program written in C was the UNIX operating system, and for many years C was considered to be inextricably linked with UNIX. Now, however, C is an important language independent of UNIX. Although it is a high-level language, C is much cl ...

Otherwise, the term object-oriented is generally used to describe a system that deals primarily with different types of objects, and where the actions you can take depend on what type of object you are manipulating. For example an object-oriented draw program might enable you to draw many types of objects, such as circles, rectangles, triangles, etc. Applying the same action to each of these objects, however, would produce different results. If the action is Make 3D, for instance, the result would be a ...

Bill Gates And Economics - 1,297 words
On October 28, 1955, William Henry Gates, lll, was born. Gates and his two sisters grew up in Seattle, Washington. His late mother was a teacher and his father is a lawyer. Gates went to public school until junior high in which he attended Lakeside School, where he met Paul Allen. In 1968, at the age 13, Gates began programming computers. Soon afterward, Gates, Allen, and some other students convinced a computer company to give them full access to a new minicomputer; in exchange they would try to find flaws in the system. Gates spent most of his time on the computer figuring out its program language. In 1972, Gates and Allen started their first business. They made car-counting machines for t ...

While you can learn to use the Internet without knowing Unix, you can't be an Internet hacker without understanding it. For this reason, the hacker culture today is pretty strongly Unix-centered. (This wasn't always true, and some old-time hackers aren't happy about it, but the symbiosis between Unix and the Internet has become strong enough that even Microsoft's muscle doesn't seem able to seriously dent it.) So, bring up a Unix -- I like Linux myself but there are other ways (and yes, you can run both Linux and DOS/Windows on the same machine). Learn it. Run it. Tinker with it. Talk to the Internet with it. ...

The Matrix - 4,268 words
Reality Bytes: A journey through perceptions of reality in 'The Matrix' and the technological world. The idea for this dissertation arose from the culmination of a number of thoughts that have interested me for some time. The question of 'reality' has always intrigued me. I perceived it as tangible and exact but at the same time intensely vulnerable. I saw the frailties of 'reality' exposed by the many differing ways it can be perceived. These differences of perception can be attributed to factors such as age, sex, colour, nationality, religion, political views, all of which alter the way we process what are presented to us as 'facts' by our senses. So numerous are these factors, I reasoned, ...
