  • Kenai.com Infrastructure Will Be Coming to java.net

    editor
    8 Feb 2010 | 9:47 am
    Our java.net spotlight this week is the announcement by Oracle's Ted Farrell about the future of Kenai.com and its infrastructure. Prior to Ted's announcement, all that was known publicly was that Kenai was going to be closed down. It turns out that, while that's true with respect to the domain name, it's not true that the Kenai infrastructure and project contents will be eliminated. Here's Ted's complete message: Gentlepeople, In an effort to get information out to the Kenai community quickly, while trying to manage the integration of our two companies, I think we did a poor job at…

  • New Poll: Does Your Company Use an Enterprise Repository Manager?

    editor

    This week's new java.net poll asks Does your company use an enterprise repository manager for development? A month ago we published John Ferguson Smart's article, Maven Repository Managers for the Enterprise. The larger the developer team, and the more diverse the products the team produces, the greater the benefits of using a repository manager become. As John says: A correctly-configured repository manager can speed up your builds, save bandwidth, help you share artifacts within your organization, and give you better control as to what dependencies are used in your projects and where they…

  • Incorporating Neural Networks into Java Apps

    4 Feb 2010 | 2:00 pm
    On NetBeans Zone there has been a good three part series of articles about Neuroph, a Java framework for developing neural networks. Part 1 and part 2 focus on what neural networks are and what they are typically used for. Basically a neural network is a structured model of nodes that map input data to an output. The model changes as it assigns weights to the connections between the nodes based on a training process with a set of data. What really caught my eye was part 3 on using a neural network for image recognition. There's a demo application called easyNeurons that makes trying out a…

    2 Feb 2010 | 5:30 am
    There are two ways of Thread creation either by implementing Runnable or extending the Thread class. In both the cases you need to start the thread for getting the functionality you need. So in order to start a thread we need a method which is start() and it is invoked on Thread object. Remember:-start() method is always invoked on Thread object to start a separate call stack of this thread,but if you call the run() method on your Runnable object then it is simply a method call and cannot initiate a separate call stack.

    Vaibhav Pandey
    19 Jan 2010 | 5:30 am
    In the previous tutorials about Threads we have learnt about the basics of Threads,How to create a Thread and also how to start a Thread. So far we have learnt how to start a single Thread but in this tutorial we will learn about how we can start and run Multiple Threads To start Multiple Threads we use Runnable interface method which is best one. So we will implement the Runnable interface in our class and use the instance of our class to start Threads. To start a Thread we simply need a method start() to begin all the Threads. Consider following example it will help you understand the…

  • Initializing Your Java Dynamically Using Any Expression

    Vaibhav Pandey
    5 Jan 2010 | 6:03 am
    There are two types of variable mainly:- 1. Instance Variable or Class Variable2. Local Variable or method variable Instance variable are initialized by JVM to their default values if not defined explicitly. Whereas the local variables needs to be defined each time time they are declared. But the local variables can be used to a greater effect by using the concept of dynamic initialization. Dynamic Initialization can be defined as the dynamic operation that allows variables to be initialized dynamically using any expression valid at the time of the variable declaration. Above definition…

  • Understanding The Java Trade Offs Between Speed And Efficiency

    22 Dec 2009 | 5:30 am
    Java is a common programming language and the basic purpose of Java is to develop network programs. Now it is also used to develop system software’s and programs too. The Java architecture has trade off between speed and efficiency. In case of Java the efficiency beats the speed the execution and rightly so because there are issues which are needed to be addressed in order to become a sound programming language. Java has some incredible features which are not in any programming language. But these features comes at some price. The features offered by Java makes Java programs slow in…

  • Learning To Use The Java Sandbox

    Vaibhav Pandey
    8 Dec 2009 | 5:30 am
    The sandbox allows code to be downloaded from any source,but applies restriction on it upon execution. You can also say sandbox isolates particular code during execution to apply the restrictions. A Java sandbox is an area in memory outside which the Java program cannot make calls. This prevents Java programs from being able to call low level system functions that may cause data corruption or other damages. The Java sandbox is used by Java to discourage unsafe applets from accessing the resources. It applies several restrictions on the applets. The Java sandbox has three components:- The…

    Having spent most of my life turning science fiction into reality, I'm incredibly amused by the recent Blessing of the Plow service performed in London. Another step in the journey: The congregation at St Lawrence Jewry in the City of London raised their mobiles and iPods above their heads and Canon Parrott raised his voice to the heavens to address the Lord God of all Creation. “May our tongues be gentle, our e-mails be simple and our websites be accessible,” he said. Great efforts have been made to modernise the Church of England, but its liturgy dates from before the arrival of the…

These are all cranked to eleven. Update: for those who don't get the say "Tweet" again design, you'll just have to watch Pulp Fiction.

    Lots of people have opined on Apple's iPad, many deriding it's closed nature and lack of features.  The thing is, those problems don't matter to most people. The iPad isn't for you or me. It's for everyone else. I've spent the last 20 years hoping we would have the technology to build such a device, even though I knew it was a device I would not personally use. But that doesn't matter.. Make no mistake, the simplified and locked down iPhone OS (running on both the iPhone and the iPad) is the future. Eventually at least 90% of people will use an iPhone, Chrome Pad, netbook, or similar…

    You might be wondering where I've been the past few months. JavaFX and Java Store work has definitely heated up, which has taken up the bulk of my time. I've also been working on Project Maitai, a tool for reactive visual artwork, as well as traveling to Sweden to speak at OreDev. Now that the Oracle acquisition has received approval (or at least been approved to receive approval), I'm hoping that things will move ahead quickly and we can all get back to writing great software. JavaFX I've been playing with JavaFX 1.3 and I have to say it's great. Even with the new graphics stack and compiler…

    As many of you may know, user interface design is a passion of mine. I want software that both looks pretty and acts well. I've had lots of ideas on the topic, often bleeding over into art and traditional design, in addition to usability. After thinking about it for a couple of years I've finally decided to create a blog dedicated to the topic: www.joshondesign.com At Josh On Design I'll be writing on art, design, and usability, but with a twist. There are plenty of design sites that focus on professional designers. My site will focus specifically on design for software engineers. It's an…

    One of the big announcements at JavaOne was the Java Store. I'm especially proud of it because I've been secretly working on the project for the past few months. Since the announcement I've gotten a lot of questions on the store and how it relates to the rest of the Java ecosystem. To supplement the excellent FAQ I thought I'd answer a few questions. What's the one paragraph summary of what you've announced? We have announced the private beta of the Java Store, a desktop client to let people browse and purchase desktop Java applications, and the open beta of the Java warehouse where…

Lots of JavaFX related things were announced at JavaOne, many of them concerning future products and other bits that aren't released yet. This post won't cover any of those. There were so many things discussed at JavaOne that I'm afraid some of the key points of the new JavaFX might have been missed. In this post I'm only going to cover the things that you can actually download and work with today. I'm talking only about the new version…

    We knew Xmlvm, a Java to Objective-C cross-compiler (that uses XSL stylesheets to transform JVM calls to Objective-C instructions) – that also provides a subset of Cocoa APIs in Java. Now we can discover iSpectrum from FlexyCore (french startup founded in 2008 by people that worked at INRIA and Texas Instruments), a solution composed of an Eclipse plugin (3.4 version min), Java ports of iPhone APIs (UIKit, CoreLocation, MediaPlayer), and an emulator. The Java code is compiled into Objective-C, and the Eclipse debugger is available. Compiling and using the emulator however require an…

  • N-Gram Language Guessing with NGramJ

    rsmudge
    8 Feb 2010 | 3:14 pm
    NGramJ is a Java library for language recognition. It uses language profiles (counts of character sequences) to guess what language some arbitrary text is. In this post I’ll briefly show you how to use it from the command-line and the Java API. I’ll also show you how to generate a new language profile. I’m doing this so I don’t have to figure out how to do it again. Running You can get a feel for how well NGramJ works by trying it on the command line. For example: $ cat >a.txt This is a test. $ java -jar cngram.jar -lang2 a.txt speed: en:0.667 ru:0.000 pt:0.000 ..

    Aims. Aims are a good thing to have, but whether you have the motivation to achieve your aims, is the problem. Motivation is a rare thing in your standard person, if we’re honest, we can say that probably over 50% of people are very lazy. If you’re like me, you say you really want to do something – but never get around to doing it. I’ve got some aims for my life, and this year, that I’d love to achieve, but then as I said, whether I have the motivation to try and get these aims, is a different matter. There are things that can motivate us to achive them, such as…
