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%). Java leaves runner ups Visual Basic.NET (+1.51%) and Python (+1.24%) far behind. Java's rise goes hand in hand with Objective-C's decline (-5.88%). So what is the outlook for 2016? The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system.

AlloCiné : Cinéma, Séries TV, Stars, Vidéos, DVD et VOD Writing a UPnP Service This chapter explains how to implement a UPnP service using GUPnP. For this example we will create a virtual UPnP-enabled light bulb. Before any code can be written, the device and services that it implement need to be described in XML. The first step is to write the device description file. <? The specVersion tag defines what version of the UPnP Device Architecture the document conforms to. Next there is the root device tag. Next we have friendlyName, manufacturer and modelName. Next there is the UDN, or Unique Device Name. Finally we have the serviceList which describes the services this device provides. Becase we are using a standard service we can use the service description from the specification. <? Again, the specVersion tag defines the UPnP version that is being used. Every action has a name and a list of arguments. stateVariables need to specify their name and dataType. Before starting to implement the device, some boilerplate code is needed to initialise GUPnP.
App Inventor for Android App Inventor for Android is an open-source web application originally provided by Google, and now maintained by the Massachusetts Institute of Technology (MIT). App Inventor and the projects on which it is based are informed by constructionist learning theories, which emphasizes that programming can be a vehicle for engaging powerful ideas through active learning. As such, it is part of an ongoing movement in computers and education that began with the work of Seymour Papert and the MIT Logo Group in the 1960s and has also manifested itself with Mitchel Resnick's work on Lego Mindstorms and StarLogo.[1][2] Implementation[edit] App Inventor includes: History[edit] The application was made available through request on July 12, 2010, and released publicly on December 15, 2010. On December 6, 2013 (the start of the Hour of Code),[8] MIT released App Inventor 2, renaming the original version "App Inventor Classic"[9] Major differences are: See also[edit] References[edit] External links[edit]

On Unix, Linux and OS X systems start Gnuplot by simply opening a terminal and typing: gnuplot For help on any topic type help followed by the name of the topic. In general, any mathematical expression accepted by C, FORTRAN, Pascal, or BASIC may be plotted. The supported functions include: The supported operators in Gnuplot are the same as the corresponding operators in the C programming language, except that most operators accept integer, real, and complex arguments. 3. plot and splot are the primary commands in Gnuplot. where either a [function] or the name of a data file enclosed in quotes is supplied.
An iPhone Lover’s Confession: I Switched To the Nexus 4. Completely. First things first, I’d love to get in touch on Google+ and Twitter (@ralf). Over the past few years I’ve invested a lot into Apple products and services. If you’d come by my house, you’d find four of the latest Apple TVs, two iMacs, the latest MacBook Air, a MacBook Pro, more than five AirPort Express stations and Apple’s Time Capsule. You could touch every single iPhone, from the first up to the iPhone 5, iPads ranging from first generation to fourth and we’ve lately added two iPad minis. My iTunes Library comprises well over 8.000 songs – all purchased via the iTunes Store. The reach of Apple’s products goes beyond my personal life. As the co-founder of Germany’s largest mobile development shop, I’m dealing with apps – predominantly iOS powered – in my daily professional life. Driven primarily by the business I run, I tried to give Android a chance more than once. And then I got the Nexus 4. In this somewhat lengthy post, I’ll try to explain why. Summary This has changed completely.
Beginning and Intermediate-Level Servlet and JSP Tutorials The beginning and intermediate-level tutorials on this page were originally based on the second edition of Marty's book Core Servlets and JavaServer Pages, but have been extensively upgraded since then, including coverage of servlets 3.0 and JSP 2.2 (e.g., for Tomcat 7). The materials have been tested by Marty in live training courses in Canada, Australia, Puerto Rico, Japan, Cambodia, Mexico, India, Norway, the Philippines, and dozens of US venues. Click on a topic below to get the detailed tutorial, download the source code, or get the exercises on the topic. Practice is the key to learning, so if you serious about learning the technology, you should do at least some of the exercises in each topic before moving on to the next topic. These tutorials assume that you already know Java; they definitely move too fast for those without prior Java experience. If you find these free tutorials helpful, we would appreciate it if you would link to us.
