Multiplexing is the ability to send more than one signal over a single line or connection. In OpenSSH, multiplexing can re-use an existing outgoing TCP connection for multiple concurrent SSH sessions to a remote SSH server, avoiding the overhead of creating a new TCP connection and reauthenticating each time. An advantage of SSH multiplexing is that the overhead of creating new TCP connections and

The Julia programming language is easy to use, fast, and powerful. This wikibook is intended as an introduction to the language for the less experienced and occasional programmer. For more learning materials, including links to books, videos, articles/blogs and notebooks, refer to the learning section at Julia's official site. See Jobs for types of jobs and companies using Julia. The official Juli

One of the many things that can be used with Applescript, is System Events. To use the System Event application, you must first give it a "tell" command.

It is very likely that at one point you will want to draw text with OpenGL. It may seem like a very basic functionality of any drawing API, but you will not find any function in OpenGL that deals with text. There are good reasons for that: text is much more complicated than you think. If you are American and use a fixed-width font, then life is simple. You don't have more than 128 possible charact

A cow smiley. All images in this section are by Mariana Ruiz Villarreal (a.k.a. LadyofHats). This tutorial covers toon shading (also known as cel shading) as an example of non-photorealistic rendering techniques. It is one of several tutorials about lighting that go beyond the Phong reflection model. However, it is based on per-pixel lighting with the Phong reflection model as described in Section

The purpose of any exercise is to steadily develop skills and to acquire the automatic algorithms for fulfilling certain operations. As for the SQL language, practical exercises are intended to enable the database programmer to quickly devise SQL queries in order to solve practically any problem, by having already studied similar problems in exercises. This book provides such a collection of pract

Cg programming in the game engine Unity is considerably easier than Cg programming for an OpenGL or Direct3D application. Import of meshes and images (i.e. textures) is supported by a graphical user interface; mipmaps and normal maps can be computed automatically; the most common vertex attributes and uniforms are predefined; OpenGL and Direct3D states can be set by very simple commands; etc. A fr

For any academic/research writing, incorporating references into a document is an important task. Fortunately, LaTeX has a variety of features that make dealing with references much simpler, including built-in support for citing references. However, a much more powerful and flexible solution is achieved thanks to an auxiliary tool called BibTeX (which comes bundled as standard with LaTeX). Recentl

Common dynamic programming implementations for the Longest Common Substring algorithm runs in O(nm) time. All of these implementations also use O(nm) storage. The astute reader will notice that only the previous column of the grid storing the dynamic state is ever actually used in computing the next column. Thus, these algorithm can be altered to have only an O(n) storage requirement. By reassigni

LaTeX and the document class will normally take care of page layout issues for you. For submission to an academic publication, this entire topic will be out of your hands, as the publishers want to control the presentation. However, for your own documents, there are some obvious settings that you may wish to change: margins, page orientation and columns, to name but three. The purpose of this tuto

The latest reviewed version was checked on 27 March 2022. There are 3 pending changes awaiting review. OpenGL logo Welcome to the OpenGL Programming book. OpenGL is an API used for drawing 3D graphics. OpenGL is not a programming language; an OpenGL application is typically written in C or C++. What OpenGL does allow you to do is draw attractive, realistic 3D graphics with minimal effort. The API

At first glance, the fix function may appear odd and useless . However, there is a theoretical reason for its existence: introducing it into the (typed) lambda calculus as a primitive allows you to define recursive functions. fix is simply defined as: fix :: (a -> a) -> a fix f = let {x = f x} in x Doesn't that seem ... magical? You might be wondering: surely fix f will cause an infinite series of

Ruby GUI toolkits are typically 3rd party GUI platforms that are driven (wrapped) by a Ruby driver. Ruby bindings are available for several widget toolkits, among them Tk, Gtk, Fox, Qt, and SWT. QtRuby gives you Ruby bindings to the Qt toolkit (the toolkit used in the KDE desktop system).

Erlang is a general purpose, concurrency-oriented functional programming language suited for fault-tolerant, distributed, soft real-time systems. It features strong dynamic typing, lightweight concurrency, eager evaluation and prolog like pattern matching. Erlang was developed in the 1980s at the Ericsson Computer Science Laboratory to address a then-unfulfilled need for telecommunications program
