The Haskell Programming Language Haskell is an advanced purely-functional programming language. An open-source product of more than twenty years of cutting-edge research, it allows rapid development of robust, concise, correct software. With strong support for integration with other languages, built-in concurrency and parallelism, debuggers, profilers, rich libraries and an active community, Haskell makes it easier to produce flexible, maintainable, high-quality software.

eyestep . org Introduction Herschel is an general-purpose multiparadigm programming language. It is strongly typed, offering type inference and parametric polymorphism (generics). It is consequently object oriented (everything is a object, even functions), while its consequent multiple dispatch approach keeps a strong functional touch. The object model is class-oriented, supporting multiple inheritance as well as the separation of types (protocols, interfaces) and classes. The grammar is regular, small, and context free. View topic - Haskell vs Prolog, or "Giving Haskell a choice" I've become more and more familiar with Haskell, and more and more have I begun to realize its true potential. It's truly frightening, really. One of the things I've started to realize is how well it can adapt different programming paradigms without sacrificing its functional purity.Another language I'm quite fond of is Prolog, and I'm actually somewhat sad I haven't spent more time hacking in it.That said, I decided to try a little experiment: writing Prolog in Haskell, staying as true to Prolog as possible, and see if the forced paradigm breaks it. I'll be rather thorough in explaining how things work for the benefit of the Prolog and Haskell illiterates out there, so if you're familiar with both you might want to tl;dr, or just bask in the glory that is Prolog and Haskell combined. At first this might seem somewhat difficult. Prolog doesn't have functions or procedures, but predicates.

Functional programming Functional programming is a style of programming which models computations as the evaluation of expressions. This article is meant to describe it briefly; however, the best way to understand functional programming is to learn the basics of one of the functional programming languages (learn Haskell). 1 What is functional programming? In functional programming, programs are executed by evaluating expressions, in contrast with imperative programming where programs are composed of statements which change global state when executed. Functional programming typically avoids using mutable state.

TIOBE Software: Tiobe Index TIOBE Index for January 2016 January Headline: Java is TIOBE's Programming Language of 2015! Java has won the TIOBE Index programming language award of the year. This is because Java has the largest increase in popularity in one year time (+5.94%). Hoc - A User Extendable Interactive Language Same as their counterparts above but the C++ libraries are not included in the resulting executable program. The stand-alone interpreter The rest of this chapter describes the general aspects of the interpreter which are common to all applications that contain it. Although for concreteness we use nrniv or neuron.exe, all the examples and fragments can be typed to any program, eg. oc, that contains the interpreter. Starting the interpreter Hoc is started by typing the program name in a terminal window.

Composing Reactive Animations Conal Elliott Microsoft Research Graphics Group Copyright 1998 We have all seen a lot of wonderful looking computer graphics, and many of us have spent time playing video games or watching our kids (or their kids) play them. It is clear that computer graphics, especially interactive graphics, is an incredibly expressive medium, with potential beyond our current imagination.

CLSID Key (COM) A CLSID is a globally unique identifier that identifies a COM class object. If your server or container allows linking to its embedded objects, you need to register a CLSID for each supported class of objects. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{CLSID} Remarks Type theory In mathematics, logic, and computer science, a type theory is any of a class of formal systems, some of which can serve as alternatives to set theory as a foundation for all mathematics. In type theory, every "term" has a "type" and operations are restricted to terms of a certain type. Two well-known type theories that can serve as mathematical foundations are Alonzo Church's typed λ-calculi and Per Martin-Löf's intuitionistic type theory. History[edit] The State of Game Development: Part 1 Working on Game Developer magazine for many years, I've seen a whole lot of charts. We have our salary survey, which you may already be aware of, but we also have tech surveys, a production survey, our front line awards for best industry tools, and other interesting bits of information. We'll attempt to smash all that information together here, in this two-part series, to give you an idea of the current shape of Western game development as a whole, from what tools people are using, to how much they make, to the big trends in design and marketing. In this first installment, we'll just be talking about our charts and studies, specifically.

Hue — a functional programming language for fun & play — Rasmus Andersson Hue is one of my latest hobby projects that didn’t die after a week. It’s a functional programming language, in a sense. There are no statements in this language, but everything is an expression. An expression does something funky and returns something—hopefully—even funkier. That includes if..then..else as well as logical tests and functions. Typeclassopedia By Brent Yorgey, Originally published 12 March 2009 in issue 13 of the Monad.Reader. Ported to the Haskell wiki in November 2011 by Geheimdienst.

Structure of the Registry Each key has a name consisting of one or more printable characters. Key names are not case sensitive. Key names cannot include the backslash character (\), but any other printable character can be used. Value names and data can include the backslash character. The name of each subkey is unique with respect to the key that is immediately above it in the hierarchy. Key names are not localized into other languages, although values may be.
