  • android third party libraries

    - by Terrance
    Its hard to believe that there aren't a ton of awesome third party (possibly open source) libraries out on the web for android using java but, I cant say I have found a great many so far but, droid seems like the only notable one I've come across. Any other majorly useful android libraries out there? Sorry in advanced if there is a dupe out there somewhere (seems like there should be) but if there is by all means post it and let me know.

  • Maven Integrated View for NetBeans IDE

    - by Geertjan
    Started working on an oft-heard request from Kirk Pepperdine for an integrated view for multimodule builds for Maven projects in NetBeans IDE, as explained here. I suddenly had some kind of brainwave and solved all the remaining problems I had, by delegating to the LogicalViewProvider's node, instead of the project's node, which means I inherit all the icons, actions, package nodes, and anything else that was originally defined within the original project, in this case for the open source JAnnocessor project: Above, you can see that the Maven submodules can either be edited in-line, i.e., within the parent project, or separately, by opening them in the traditional NetBeans way. Get the module here: http://plugins.netbeans.org/plugin/45180/?show=true Some people out there might be interested in how this is achieved. First, hide the original ModulesNodeFactory in the layer. Then create the following class, which creates what you see in the screenshot above: import java.util.ArrayList; import java.util.List; import javax.swing.event.ChangeListener; import org.netbeans.api.project.Project; import org.netbeans.spi.project.SubprojectProvider; import org.netbeans.spi.project.ui.LogicalViewProvider; import org.netbeans.spi.project.ui.support.NodeFactory; import org.netbeans.spi.project.ui.support.NodeList; import org.openide.nodes.FilterNode; import org.openide.nodes.Node; @NodeFactory.Registration(projectType = "org-netbeans-modules-maven", position = 400) public class ModulesNodeFactory2 implements NodeFactory { @Override public NodeList<?> createNodes(Project prjct) { return new MavenModulesNodeList(prjct); } private class MavenModulesNodeList implements NodeList<Project> { private final Project project; public MavenModulesNodeList(Project prjct) { this.project = prjct; } @Override public List<Project> keys() { return new ArrayList<Project>( project.getLookup(). lookup(SubprojectProvider.class).getSubprojects()); } @Override public Node node(final Project project) { Node node = project.getLookup().lookup(LogicalViewProvider.class).createLogicalView(); return new FilterNode(node, new FilterNode.Children(node)); } @Override public void addChangeListener(ChangeListener cl) { } @Override public void removeChangeListener(ChangeListener cl) { } @Override public void addNotify() { } @Override public void removeNotify() { } } } Considering that there's only about 5 actual statements above, it's pretty amazing how much can be achieved with so little code. The NetBeans APIs really are very cool. Hope you like it, Kirk!

  • Map building - Tower Defense

    - by Dan K
    Before diving too deep into my question, let it be known that I am learning as far as java script goes and figured a simple Tower Defense game would be an excellent way to learn things. So I have found a simple background image with a path drawn on it and my question is how would I go about building a path so that I can animate my objects. Would I have to take the image and overlay a grid system, or can I store the path in some sort of array and have my objects move across it? Here is the background image:

  • How To Disable Individual Plug-ins in Google Chrome

    - by The Geek
    Have you ever wondered how to disable useless or insecure browser plug-ins in Google Chrome? Here’s the lowdown on how to get rid of Java, Acrobat, Silverlight, and the rest of the plugins you probably want to get rid of. Disabling Plugins in Google Chrome If you head to about:plugins in your address bar, you’ll probably see a list of plugins, but won’t be able to disable them yet. What you’ll need to do is switch over to the Dev channel of Chrome, which gives you access to all the latest features—though you might be warned that sometimes the dev channel might be less stable than the release or beta channels. Ready to proceed? Head to the Dev Channel page, and then click the link to run the installer. You’ll be prompted to restart Chrome when you’re done. Note that Mac and Windows users can both run an installer to switch. Linux users will have to install a package. Note: Once you’ve switched to the Dev channel, you can’t really switch to the stable channel. You’ll have to uninstall Chrome and then reinstall the regular version. Now that you’ve switched to the dev channel and restarted your browser, head to about:plugins in the address bar, and then just disable each plugin you really don’t need. Plugins you can generally live without?  Java, Acrobat, Microsoft Office, Windows Presentation Foundation, Silverlight. These will be on a case-by-case basis, of course, but the vast majority of large websites don’t require any of those. When it comes right down to it, the only plugin that most people require is Flash… and leave the “Default Plug-in” alone too. Special thanks to @jordanconway for pointing out the solution.

  • Something similar to Objective-C categories in other languages?

    - by adig
    I understand Objective-C categories and how they become useful, but I always have a hard time explaining the concept to other programmers that are not familiar with Objective C. Maybe I'm just bad at explaining things, but I was thinking at another way to explain it by comparing to similar features offered by other (more popular) languages. (ex : I can explain the similarities between Objective C protocols and Java Interfaces) Any examples similar to Categories ?

  • [GEEK SCHOOL] Network Security 8: Keep Your System Updated for Security and Stability

    - by Ciprian Rusen
    Another important step in securing any computer or device is setting up automated updates. Your device’s security relies on your operating system, apps, plug-ins, and programs always being up to date. For example, using outdated Internet browsers and plug-ins like Adobe Flash, Java, or Silverlight represents a big security problem. There are many websites on the Internet that exploit security bugs in your browser or the plug-ins you have installed.Click Here to Continue Reading

Live, Thursday Nov 8, 10am PT/ 1pm ET. Solving Big Problems in Our 21st Century Information Society | Irving Wladawsky-Berger "I believe that the kind of extensive collaboration between the private sector, academia and government represented by the Internet revolution will be the way we will generally tackle big problems in the 21st century. Just as with the Internet, governments have a major role to play as the catalyst for many of the big projects that the private sector will then take forward and exploit. The need for high bandwidth, robust national broadband infrastructures is but one such example." — Irving Wladawsky-Berger SOA Still Not Dead: Ratification of Governance Standard Highlights SOA’s Continued Relevance So just about the time I dig into Google Trends to learn that the conversation about governance peaked in 2004, along comes all this InfoQ article by Richard Seroter.

So how do organizations provide all stakeholders with the information they need?" Leon provides answers in this post. Thought for the Day "(When) asking skilled architects…what they do when confronted with highly complex problems…(they) would most likely answer, 'Just use Common Sense.'

  • Oracle's Cloud Strategie nach der OOW 2012

    - by Manuel Hossfeld
    Auf der diesjährigen Oracle Open World war „die Cloud“ nicht nur ein vielbenutztes Buzzword, sondern auch Anlass für einige interessante Ankündigungen. Wer keine Zeit oder Muße hatte, sich die entsprechenden Keynotes von Larry Ellison und Thomas Kurian anzuhören, erfährt in diesem Artikel die wesentlichen Änderungen. Die erste Neuerung: Oracle wird in Zukunft alle drei „Sorten“ bzw. „Ebenen“ von Cloud Computing anbieten: SaaS (Software as a Service) – die Bereitstellung von kompletten Fachanwendungen z.B. aus der eBusiness Suite in Form eines Mietmodells - gab es schon länger. Abgesehen von der Tatsache, dass hier zusätzliche/neuere Komponenten und Module der durch die letzten Zukäufe von Oracle noch breiter gewordenen Palette angeboten werden, ändert sich am Prinzip nichts. Bei PaaS (Plattform as a Service) sind vor allem die beiden bereits letztes Jahr angekündigten Dienste „Database Service“ (basierend auf APEX) und „Java Service“ (basierend auf Weblogic) zu nennen, für die nun auch konkrete Pakete und Preise (ca.175$ bis 2000$/Monat) sowie die Möglichkeit zur Anmeldung auf http://cloud.oracle.com vorliegen. Interessanterweise gehört auch ein sog. „Social Service“ in diese Schicht, mit der Oracle Kunden ihre Anwendungen in Zukunft auf standardisierte Weise durch Social Networking Funktionalität wie z.B. Microblogging erweitern können.Ebenso neu angekündigt wurde ein "Developer Service", welcher z.B. Sourcecode-Verwaltung durch GIT Repositories sowie Wikis und Issue Tracking bereit stellen soll. Die dort mittels JDeveloper, Netbeans oder Eclipse erstellten Applikationen können dann nahtlos innerhalb kürzester Zeit in den Java Service deployed werden. Komplett neu und für einige sicher überraschend ist hingegen der Bereich IaaS (Infrastructure as a Service) – Hier geht es um die Bereitstellung von Basis-Infrastrukturkomponenten wie Storage, Rechenleistung (letztlich also Betriebssysteme / VMs) und Messaging / Queueing. Genaue Details oder Preise zu den IaaS Angeboten sind noch nicht bekannt, aber zumindest zu den Storage- und Messaging Services können grundlegende Daten bereits auf http://cloud.oracle.com eingesehen werden Die zweite Neuerung: Kunden können in Zukunft als Alternative zum Betrieb der o.g. „Oracle Cloud“, diese auch komplett hinter ihrer eigenen Firewall aufbauen lassen. Mit anderen Worten: Oracle baut und betreibt bei diesem als „Oracle Private Cloud“ bezeichneten Angebot alle Komponenten selbst – die Daten verlassen aber niemals das Gebäude des Kunden. Letzteres ist gerade bei uns im Datenschutz-sensiblen Deutschland ein wichtiger Aspekt. Da die verwendeten Komponenten in beiden Fällen die gleichen sind, ist auch ein „Umziehen“ oder Erweitern der Private Cloud in die Public Cloud (oder zurück) ohne Änderungen an den Anwendungen möglich. Der Möglichkeit einer "Hybrid Cloud", bei der Teile einer Anwendung hinter der eigenen Firewall, andere Teile aber in der Oracle Cloud laufen, wird damit Realität.

  • Windows8, JavaScript and HTML5 - A good thing?

    - by Albers
    Most of us have seen the Windows 8 news regarding support for native HTML5/JavaScript applications. The press has pushed this as a potential threat to the .NET developer community because JavaScript and HTML5 were called "our new developer platform". The press release refers to "Web-connected and Web-powered apps built using HTML5 and JavaScript that have access to the full power of the PC.".Microsoft has also been hush on details related to these comments. Before we buy the hype and start worrying about a world where we drop our Visual Studio licenses and buy DreamWeaver - let's think about how Windows 8 HTML/JavaScript applications would be implemented. The HTML5 spec offers support for offline applications, but this won't offer the OS-integrated experience the press release refers to. MS has to be planning a way to extend access beyond the traditional JavaScript feature set. Microsoft has a similar option today: HTML Applications or HTAs. They come close to required features, but HTAs need ActiveX or Java integration to provide the promised OS-level access. I'm guessing that Microsoft's future OS strategy isn't built on developers cranking out ActiveX controls or Java applets. So where is Microsoft headed? One possibility is that MS builds a new JavaScript framework from the ground up outside their current APIs. Another idea would be for Microsoft to add support for JavaScript as a first class .NET language using the Dynamic Language Runtime. A solution based on the DLR could be integrated into an HTA-like model to provide the promised access, along with the full range of features in .NET Framework. Security comes included in the Framework. And the work necessary to support this integration would tie in nicely with the effort MS has recently made providing better JavaScript and HTML5 support in Visual Studio 2010. As a bonus, a full-fledged JavaScript DLR implementation would allow single language web solutions across client and server (think node.js) and would appeal to developers who are familiar with JavaScript but have less experience with the Microsoft tech stack. We will all get a better picture after the Build conference in September. But in the mean time we know that Microsoft has a reputation for providing strong developer support. We might want to reserve our harshest judgement and consider that the press release could hint at new opportunities for .NET development.

  • Library to fake intermittent failures according to tester-defined policy?

    - by crosstalk
    I'm looking for a library that I can use to help mock a program component that works only intermittently - usually, it works fine, but sometimes it fails. For example, suppose I need to read data from a file, and my program has to avoid crashing or hanging when a read fails due to a disk head crash. I'd like to model that by having a mock data reader function that returns mock data 90% of the time, but hangs or returns garbage otherwise. Or, if I'm stress-testing my full program, I could turn on debugging code in my real data reader module to make it return real data 90% of the time and hang otherwise. Now, obviously, in this particular example I could just code up my mock manually to test against a random() routine. However, I was looking for a system that allows implementing any failure policy I want, including: Fail randomly 10% of the time Succeed 10 times, fail 4 times, repeat Fail semi-randomly, such that one failure tends to be followed by a burst of more failures Any policy the tester wants to define Furthermore, I'd like to be able to change the failure policy at runtime, using either code internal to the program under test, or external knobs or switches (though the latter can be implemented with the former). In pig-Java, I'd envision a FailureFaker interface like so: interface FailureFaker { /** Return true if and only if the mocked operation succeeded. Implementors should override this method with versions consistent with their failure policy. */ public boolean attempt(); } And each failure policy would be a class implementing FailureFaker; for example there would be a PatternFailureFaker that would succeed N times, then fail M times, then repeat, and a AlwaysFailFailureFaker that I'd use temporarily when I need to simulate, say, someone removing the external hard drive my data was on. The policy could then be used (and changed) in my mock object code like so: class MyMockComponent { FailureFaker faker; public void doSomething() { if (faker.attempt()) { // ... } else { throw new RuntimeException(); } } void setFailurePolicy (FailureFaker policy) { this.faker = policy; } } Now, this seems like something that would be part of a mocking library, so I wouldn't be surprised if it's been done before. (In fact, I got the idea from Steve Maguire's Writing Solid Code, where he discusses this exact idea on pages 228-231, saying that such facilities were common in Microsoft code of that early-90's era.) However, I'm only familiar with EasyMock and jMockit for Java, and neither AFAIK have this function, or something similar with different syntax. Hence, the question: Do such libraries as I've described above exist? If they do, where have you found them useful? If you haven't found them useful, why not?

  • Tweaking AStar to find closest location to unreachable destination

    - by Shivan Dragon
    I've implemented AStar in Java and it works ok for an area with obstacles where the chosen destination is reachable. However, when the destination is unreachable, the calculated "path" is in no way to the closest location (to the unreachable location) but is instead some random path. Is there a feasible way to tweak AStar into finding the path to the closest location to an unreachable destination?

  • What are the arguments against parsing the Cthulhu way?

    - by smarmy53
    I have been assigned the task of implementing a Domain Specific Language for a tool that may become quite important for the company. The language is simple but not trivial, it already allows nested loops, string concatenation, etc. and it is practically sure that other constructs will be added as the project advances. I know by experience that writing a lexer/parser by hand -unless the grammar is trivial- is a time consuming and error prone process. So I was left with two options: a parser generator à la yacc or a combinator library like Parsec. The former was good as well but I picked the latter for various reasons, and implemented the solution in a functional language. The result is pretty spectacular to my eyes, the code is very concise, elegant and readable/fluent. I concede it may look a bit weird if you never programmed in anything other than java/c#, but then this would be true of anything not written in java/c#. At some point however, I've been literally attacked by a co-worker. After a quick glance at my screen he declared that the code is uncomprehensible and that I should not reinvent parsing but just use a stack and String.Split like everybody does. He made a lot of noise, and I could not convince him, partially because I've been taken by surprise and had no clear explanation, partially because his opinion was immutable (no pun intended). I even offered to explain him the language, but to no avail. I'm positive the discussion is going to re-surface in front of management, so I'm preparing some solid arguments. These are the first few reasons that come to my mind to avoid a String.Split-based solution: you need lot of ifs to handle special cases and things quickly spiral out of control lots of hardcoded array indexes makes maintenance painful extremely difficult to handle things like a function call as a method argument (ex. add( (add a, b), c) very difficult to provide meaningful error messages in case of syntax errors (very likely to happen) I'm all for simplicity, clarity and avoiding unnecessary smart-cryptic stuff, but I also believe it's a mistake to dumb down every part of the codebase so that even a burger flipper can understand it. It's the same argument I hear for not using interfaces, not adopting separation of concerns, copying-pasting code around, etc. A minimum of technical competence and willingness to learn is required to work on a software project after all. (I won't use this argument as it will probably sound offensive, and starting a war is not going to help anybody) What are your favorite arguments against parsing the Cthulhu way?* *of course if you can convince me he's right I'll be perfectly happy as well
