The Debian Stable distribution is one of the most popular for personal computers and network servers, and has been used as a base for several other Linux distributions. Debian was first announced in 1993 by Ian Murdock, Debian 0.01 was released in August 1993, and the first stable release was made in 1996.
When you first create a new Debian 8 server, there are a few configuration steps that you should take early on as part of the basic setup. This will increase the security and usability of your server and will give you a solid foundation for subsequent actions.
These resources are then returned to the client as though they originated from the server itself (or servers themselves). While a forward proxy acts as an intermediary for its (usually nearby) associated clients and returns to them resources accessible on the Internet, a reverse proxy acts as an intermediary for its (usually nearby) associated servers and only returns resources provided by those associated servers.
In the first part of this book, we will explore the history and importance of design patterns which can really be applied to any programming language. If you’re already sold on or are familiar with this history, feel free to skip to the chapter “What is a Pattern?” to continue reading.
Design patterns can be traced back to the early work of an architect named Christopher Alexander. He would often write publications about his experience in solving design issues and how they related to buildings and towns. One day, it occurred to Alexander that when used time and time again, certain design constructs lead to a desired optimal effect.
Node.js uses an event-driven, non-blocking model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. This simple web server written in Node responds with “Hello World” for every request. To run the server, put the code into a file example.js and execute it with the node program from the command line.
Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types.
I don’t believe you have to be better than everybody else. I believe you have to be better than you ever thought you could be.— Ken Venturi
A mountain range is a geographic area containing numerous geologically related mountains. A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related.
A lot of mobile-minded talented folks across the globe produce great work, but yet sometimes you still hear many of them complain about their relationships with their clients. They often mention feeling isolated and not truly understanding what the client really needed.
Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation semantics (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can also be applied to any kind of XML document, including plain XML, SVG and XUL.
Before you begin this guide, you should have a regular, non-root user with sudo privileges configured on your server. You can learn how to configure a regular user account by following steps 1-4 in our initial server setup guide for Ubuntu 14.04.
Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film. The captured images are digitized and stored as a computer file ready for further digital processing, viewing, digital publishing or printing.
Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing.
