Dr Dobbs - F#: Putting the 'Fun' into 'Functional' - 0 views

  • You would be forgiven if you thought the "F" in F# -- which made its debut as part of Visual Studio 2010 -- stands for "functional." After all, F# (pronounced "F sharp") is a functional programming language for the .NET Framework that combines the succinct, expressive, and compositional style of functional programming with the runtime, libraries, interoperability, and object model of .NET. But Don Syme, inventor of F# and leader of the team that incubated the language, has a different, truncated, and entirely whimsical definition. "In the F# team," says Syme, a principal researcher at Microsoft Research Cambridge, "We say, 'F is for Fun.' F# enables users to write simple code to solve complex problems. Programming with F# really does make many programming tasks simpler, and our users have consistently reported that they've found using the language enjoyable." Indeed, F#, which has been developed in a partnership between Microsoft Research and the Microsoft Developer Division, is already popular with the .NET developer community. The language is widely known in the academic community and among thought leaders, and the list of admirers will only increase as Visual F#, the result of a partnership between Microsoft Research Cambridge and Microsoft's Developer Division, becomes a first-class language in Visual Studio 2010.

Xtext - A Language Development Framework | Eclipse Live - 0 views

  • On June 23, the new Xtext version 1.0 will be released as part of Eclipse's annual release train. During the last year Xtext has grown from a tiny DSL editor generator, to a full-blown language development framework. With Xtext 1.0 you can develop complex programming languages and you not only get an advanced editor, but a complete integrated development environment (IDE) based on Eclipse. The new workspace indexer and the builder infrastructure enable sophisticated IDE features, as we will demonstrate in this webinar. The new JVM-types allow you to link to and integrate with any Java element and Eclipse's JDT. During the webinar we will give a short overview on Xtext and how it works behind the scenes. We will demo different aspects of the framework’s features and show how to implement an interpreter for arithmetic expressions. The 60 minutes will be a great opportunity for you to get in touch with the Xtext core committers, ask questions and learn about the new and noteworthy features in version 1.0.

Don Syme's WebLog on F# and Related Topics : F# 2.0 Released - 0 views

  • Today sees the launch of Visual Studio 2010, at five launch events around the world, as announced by Bob Muglia, Jason Zander and S. Somasegar, and presented live today in Las Vegas.   Visual Studio 2010 includes the official version 2.0 of the F# language. As is our custom on the F# team, we also release a matching MSI and ZIP of F# 2.0 (for use with Visual Studio 2008 and as a standalone compiler on a range of platforms)   Today represents the culmination of 7 years of work on the language at Microsoft Research, and, more recently, the Microsoft Developer Division. I am immensely proud of what we’ve achieved. F# brings a productive functional and object-oriented programming language to .NET, extending the platform to new audiences in technical, algorithmic, data-rich, parallel and explorative domains, and its inclusion in Visual Studio 2010 represents a huge milestone for the language.   To help understand what we’re doing with F#, I’ve listed some of the common questions people have about the language below.  We thank everyone who has been involved in the production of F#, especially the many users who have given us feedback on the language!

Extending Visual Studio - 0 views

  •  
    Visual Studio provides very powerful capabilities for us to extend its functional using various technologies and approaches. You can both automate routine actions using simplest macros and carry out a deep integration of any third-party or your own user components. In fact, while extending Visual Studio, you are limited only by your own imagination, so you can realize such eccentric solutions as integration of your favorite Instant Messenger client into the project window, or even an "achievements for developers" ( http://visualstudiogallery.msdn.microsoft.com/bc7a433b-b594-48d4-bba2-a2f24774d02f ) system like in videogames! After all, any serious developer must know and be able to adjust the development environment to his/her own needs, as well as be able to handle its possible "glitches". At the same time, creating extensions is nowadays simple and transparent as never before, regardless of your previous experience of working with Visual Studio! You can both integrate a native library module that will be able to directly handle the low-level COM interfaces of the API environment, and a managed build that will have an access to almost all of these APIs through convenient managed wraps. While the native unit will surely provide the developer with the absolute control over the situation, using managed builds for extensions will help you get rid of a very complicated process of calculating the number of COM-objects instances and direct memory handling, allowing you to focus on implementing the functionality you need with all the power .NET Framework and Common Language Runtime can provide. If you've got interested in the subject of extending Visual Studio, you can try it right now starting with 3 simple steps described in this article. This guide will allow you to create a completely functional managed extension module for all the Visual Studio versions literally within 10 minutes and start using your functional at once, while the rest articles of this series

C9 Lectures: Dr. Don Syme - Introduction to F#, 1 of 3 | Going Deep | Channel 9 - 0 views

  • F# is Microsoft's first functional programming language to be included as one of Visual Studio's official set of languages. F# is a succinct, efficient, expressive functional/object-oriented programming language under joint development by Microsoft Developer Division and Microsoft Research. During the course of Erik Meijer's fantastic lecture series on functional programming fundamentals several of you asked for examples of specific topics in F#. Well, we listened. Dr. Don Syme is a principal researcher in MSR Cambridge. He has a rich history in programming language research, design, and implementation (C# generics being one of his most recognized implementations), and is the principle creator of F#. Who better to lecture on the topic than Don? This three part series will serve as an introduction to F#, including insights into the rationale behind the history and creation of Microsoft's newest language.

The Unheralded Benefits of the F# Programming Language « The Nomadic Developer - 0 views

  • As many long time readers know, I am an enthusiast of the F# programming language.  I make no apologies for the fact that, if you are developing software on the .NET platform, F# is one of the better choices you can make for numerous reasons.  It is one of the reasons I proudly contributed as a co-author to the book, Professional F# 2.0, which is being published by Wrox in October. Some of the oft cited benefits of F# are that, to distill them quickly, it is good at doing intensely mathematical operations, it is built for parallelism, and it is good at helping define domain specific languages.  Those benefits are so often cited by speakers on the F# speaker circuit that they pretty much seem cliche to me at this point (note, yours truly is proud to call himself a member of said circuit, and often gives this talk!)  As great as these features are, there are a couple features, that in my more mundane F# experiences, seem to stand out as things that “save my ass”, for lack of a better phrase, more often than not.

Develop Web Apps in F# with WebSharper | .NET Zone - 0 views

  • In ASP.NET development, F# also offers productivity advantages over VB and C#.  F# is different because it is statically checked and type-safe.  It addresses weaknesses in ASP.NET development like untyped values, complex form construction, and using strings for IDs and method names that connect markup with code-behind (class-files).  Writing a web application in F# on the WebSharper platform can be less-time consuming if a developer is not great at writing web apps in JavaScript.  Through WebSharper, developers can write a web app using a large subset of F# and .NET core libraries and then just let WebSharper map the code to JavaScript.  WebSharper can integrate with ASP.NET applications, but it is different from the standard approach because it builds applications from miniature web pages called "pagelets".  The pagelets correspond to functions on the client-side and they are automatically translated into JavaScript.   WebSharper supports a wide range of JavaScript libraries, making it easy for developers to optimize their code in whatever way they choose.  jQuery, qooxdoo, Flapjax, and Yahoo UI are all supported by WebSharper.  The leap from F# to JavaScript is manageable because both are functional languages that support lambda expressions and closures.  Another unique part of WebSharper is a "formlet".  A formlet is a special pagelet that provides form functionality.  Formlets in Web Sharper run and validate on the client, submitting their result to a either a client- or a server-side callback.

Could you help me, please? Static analysis of C++Builder and WinRT projects. - 0 views

  •  
    m addressing developers with a specific request. Our plans for the PVS-Studio 5.00 static code analyzer are to implement integration with the C++Builder environment and support for the C++/CX language extension. Unfortunately, we have very few projects developed in that environment or involving that extension, and we find it therefore difficult to test the new functionality. That's why I'm asking the community to share the source codes of your projects with us. Now let's speak of it all in detail. Continue: http://www.viva64.com/en/b/0184/

InfoQ: Erlang Style Concurrency for .NET Applications Part 1 - CCR - 0 views

  • Erlang allows for massively scalable concurrency, often with millions of lightweight, thread-like components known as actors. Unfortunately, using Erlang requires rewriting all of your legacy code into a rather esoteric language. But there are other options, such as the little known CCR platform that was developed by .NET's robotics department. Actor based languages such as Erlang are able to achieve high degrees of parallelism by using the Actor model. Under this model the fundamental unit of concurrency is not a thread or fiber, but rather something much smaller. Known as a "process" in Erlang, each unit of concurrency has a base overhead of about 1200 bytes on a 32-bit system. By comparison, a thread on the Windows operating system defaults to 1 MB just for the stack, additional space is also needed for bookkeeping and thread local storage. Because they are so lightweight, an application can spawn literally millions of processes simultaneously.

All possible ways to run java program. - 0 views

  •  
    During compilation phase Java compiler compiles the source code and generates bytecode. This intermediate bytecode is saved in form of a .class file. In second phase, Java virtual machine (JVM) also called Java interpreter takes the .class as input and generates output by executing the bytecode. Java is an object oriented programming language; therefore, a program in Java is made of one or more classes. No matter how trivial a Java program is, it must be written in form of a class.

Vale Java? Scala Vala palava - O'Reilly Broadcast - 0 views

  • Dave Megginson (who drove the development of the SAX API that will be familiar to many XML developers who use Java) recently wrote Java is dead. Java stood out as a programming language (though not as a platform) in that Sun had refused to standardize it through an independent and reputable standards organization (a lot of the hard work had been done in one attempt to put it through ECMA and one to put it through ISO, both times Sun pulled out and eventually made their highly unsatisfactory JCP Java Community Process system.) Without the ability to alter Java significantly in ways that might go against their druthers, Java suffered two major forks (Microsoft's J++ then its C#, and IBM's SWT) where significant players disagreed with a major component (the graphics library). Java succeeded in middleware, and but failed to take advantage of the rise of browsers on the deskop: their HTML parser was great for the middle 1990s but was deliberately neglected to the point of being unusable: it is hard not to see this as a deliberate attempt by Sun to leave the browser market to its friends and enemies. I really liked Java, and bet my company on it (in a sense): I would not do that today.

OOPHP- The Basics Of Classes And Objects - PHP Tutorials | Dream.In.Code - 1 views

  • As PHP is not a strictly OOP language, it is very easy to slip into sloppier and more procedural code as well as program in PHP one's entire career and not deal with OOP at all. In this tutorial, I will cover the following: Why use OOP over procedural programming, as I have been doing?Encapsulation and modularityBasic class design

ScalaModules: a DSL for bringing OSGi to Scala | Lambda the Ultimate - 0 views

  • ScalaModules is an open source project aimed at providing fluent support for OSGi to Scala developers. It takes advantage of Scala's infix operator notation, higher order functions, and implicit conversions. ScalaModules transparently uses the Scala compiler to wrap an OSGi BundleContext with its own RichBundleContext model. This general technique is not unusual for creating DSLs in mainstream languages. Sean McDirmid uses similar tricks for his C# Bling library for WPF, except that Bling must overcome the lack of C# offering comparable extensions to Scala.

Introduction to CRUD Functions in PHP - 0 views

  • Building a dynamic PHP site requires you to understand how CRUD (create, read, update, delete) functions work. There are a variety of ways to implement these functions include databases, and most commonly through mySQL.  With these functions you can add new entries to the database (registration), view existing entries (retrieve users or fields), update the entries to your table or delete users (who may unsubscribe or permanently delete their accounts.) For a user account based sites, these functions are essential for keeping your user and information database up to date.
