• Is there a visual web application builder or rapid webapp prototyping framework?

  - by Jesper Mortensen

  Question: Is there such a thing as a self-hosted framework or CMS especially tailored towards the creation of interactive web applications without -- or with an absolute minimum of -- programming? (Substantially less programming than say a simple Rails app or a plugin for Wordpress, Joomla etc would require.) As for desired features I'd settle for whatever is available, but some ideas could be: A User authentication and Permissions system. A GUI-driven input form builder. A GUI-driven template / visual site design builder. A simple scripting language (think AppleScript-like simplicity) A highly modular architecture, with high-level business objects (users, forms data, etc) exposed for easy re-use. If something like the above doesn't exist, then what comes near this? Need: This is for self-hosted rapid prototyping of web applications, and limited user testing of webapp user interface designs in a closed user test. Notes: I know about Ruby on Rails (Rails), Django, Pyramid etc. I'm looking for something much faster to work in, for making prototypes. I know about CMS's in general but find that most of them are tailored towards displaying information to the end users. If there is an exceptionally easy-to-master CMS with easy scripting (lets say much more so than for example Wordpress) then I'd be interested.

• Java EE @ No Fluff Just Stuff Tour

  - by reza_rahman

  If you work in the US and still don't know what the No Fluff Just Stuff (NFJS) Tour is, you are doing yourself a very serious disfavor. NFJS is by far the cheapest and most effective way to stay up to date through some world class speakers and talks. This is most certainly true for US enterprise Java developers in particular. Following the US cultural tradition of old-fashioned roadshows, NFJS is basically a set program of speakers and topics offered at major US cities year round. Many now famous world class technology speakers can trace their humble roots to NFJS. Via NFJS you basically get to have amazing training without paying for an expensive venue, lodging or travel. The events are usually on the weekends so you don't need to even skip work if you want (a great feature for consultants on tight budgets and deadlines). I am proud to share with you that I recently joined the NFJS troupe. My hope is that this will help solve the lingering problem of effectively spreading the Java EE message here in the US. For NFJS I hope my joining will help beef up perhaps much desired Java content. In any case, simply being accepted into this legendary program is an honor I could have perhaps only dreamed of a few years ago. I am very grateful to Jay Zimmerman for seeing the value in me and the Java EE content. The current speaker line-up consists of the likes of Neal Ford, Venkat Subramaniam, Nathaniel Schutta, Tim Berglund and many other great speakers. I actually had my tour debut on April 4-5 with the NFJS New York Software Symposium - basically a short train commute away from my home office. The show is traditionally one of the smaller ones and it was not that bad for a start. I look forward to doing a few more in the coming months (more on that a bit later). I had four talks back to back (really my most favorite four at the moment). The first one was a talk on JMS 2 - some of you might already know JMS is one of my most favored Java EE APIs. The slides for the talk are posted below: What’s New in Java Message Service 2 from Reza Rahman The next talk I delivered was my Cargo Tracker/Java EE + DDD talk. This talk basically overviews DDD and describes how DDD maps to Java EE using code examples/demos from the Cargo Tracker Java EE Blue Prints project. Applied Domain-Driven Design Blue Prints for Java EE from Reza Rahman The third talk I delivered was our flagship Java EE 7/8 talk. As you may know, currently the talk is basically about Java EE 7. I'll probably slowly evolve this talk to gradually transform it into a Java EE 8 talk as we move forward (I'll blog about that separately shortly). The following is the slide deck for the talk: JavaEE.Next(): Java EE 7, 8, and Beyond from Reza Rahman My last talk for the show was my JavaScript+Java EE 7 talk. This talk is basically about aligning EE 7 with the emerging JavaScript ecosystem (specifically AngularJS). The slide deck for the talk is here: JavaScript/HTML5 Rich Clients Using Java EE 7 from Reza Rahman Unsurprisingly this talk was well-attended. The demo application code is posted on GitHub. The code should be a helpful resource if this development model is something that interests you. Do let me know if you need help with it but the instructions should be fairly self-explanatory. My next NFJS show is the Central Ohio Software Symposium in Columbus on June 6-8 (sorry for the late notice - it's been a really crazy few weeks). Here's my tour schedule so far, I'll keep you up-to-date as the tour goes forward: June 6 - 8, Columbus Ohio. June 24 - 27, Denver Colorado (UberConf) - my most extensive agenda on the tour so far. July 18 - 20, Austin Texas. I hope you'll take this opportunity to get some updates on Java EE as well as the other awesome content on the tour?

• What's a "Cloud Operating System"?

  - by user12608550

  What's a "Cloud Operating System"? Oracle's recently introduced Solaris 11 has been touted as "The First Cloud OS". Interesting claim, but what exactly does it mean? To answer that, we need to recall what characteristics define a cloud and then see how Solaris 11's capabilities map to those characteristics. By now, most cloud computing professionals have at least heard of, if not adopted, the National Institute of Standards and Technology (NIST) Definition of Cloud Computing, including its vocabulary and conceptual architecture. NIST says that cloud computing includes these five characteristics: On-demand self-service Broad network access Resource pooling Rapid elasticity Measured service How does Solaris 11 support these capabilities? Well, one of the key enabling technologies for cloud computing is virtualization, and Solaris 11 along with Oracle's SPARC and x86 hardware offerings provides the full range of virtualization technologies including dynamic hardware domains, hypervisors for both x86 and SPARC systems, and efficient non-hypervisor workload virtualization with containers. This provides the elasticity needed for cloud systems by supporting on-demand creation and resizing of application environments; it supports the safe partitioning of cloud systems into multi-tenant infrastructures, adding resources as needed and deprovisioning computing resources when no longer needed, allowing for pay-only-for-usage chargeback models. For cloud computing developers, add to that the next generation of Java, and you've got the NIST requirements covered. The results, or one of them anyway, are services like the new Oracle Public Cloud. And Solaris is the ideal platform for running your Java applications. So, if you want to develop for cloud computing, for IaaS, PaaS, or SaaS, start with an operating system designed to support cloud's key requirements…start with Solaris 11.

• Reading Open Source Projects

  - by Hossein

  About my programming knowledge: I have basic knowledge of programming. Have never worked in a team project. Have done, only, a couple of small solo projects. Problem: Consider a typical open source project. We want to know about the project, so that we can contribute, test it, just out of curiosity, etc. The documentations do not describe the code architecture, usually, so RTFM(!) wouldn't apply here. They usually tend to describe how to use the software, not how it is designed. Mailing Lists in big projects are very crowded. Tens of e-mails are send in just an hour. also, following the mailing list to know the project is like understanding a film when you have arrived late, when half of the film is gone or even worse. Obviously, the code is not like a novel. So, you can't start from downloading the source code and just "start from the first page and so on"! Question: How should one understand open source project? What are the steps to do in an open source project, to understand how the whole thing works and get into speed with the "under the hood"?

• Oracle and Cavium to work together on Java SE 8 on 64-bit ARMv8

  - by Henrik Stahl

  We have been working for some time on a standard Oracle JDK 8 port to the upcoming introduction of 64-bit servers based on the new ARMv8 micro architecture. At ARM TechCon 2013 in Santa Clara, California, we announced a roadmap with an expected GA in 2015. This project is going very well and is ahead of schedule. We will soon be at the point where we will make binaries available outside of Oracle - first in a managed beta program with select customers/partners, and sometime during the fall of 2014 as a public early access program. Unless something changes, we are looking at a early 2015 GA. We should be able to share a detailed ramp down and GA plan by JavaOne 2014. One of the things we (obviously) need to produce a high-quality port is hardware for development and QA. We are therefore happy to announce that we will be collaborating with Cavium on this project. Cavium has been a supporter of the Java ecosystem for a long time and we have numerous joint customers running various Java versions on Cavium MIPS and ARM-based hardware. Cavium has now agreed to provide us with development hardware and engineering resources so that we can certify and optimize the initial Oracle JDK 8 release on Cavium's ThunderX hardware. This is expected to improve quality and performance of JDK 8 on ARMv8 in general, as well as on Cavium's hardware. For more information: Cavium announcement on the ThunderX product family Cavium announcement on Oracle collaboration As a reminder, we plan to release the Oracle JDK 8 port to 64-bit ARMv8 under the royalty-free (for general purpose servers etc) Binary Code License, but we have no current plans to open source it.

• The Endeca UI Design Pattern Library Returns

  - by Joe Lamantia

  I'm happy to announce that the Endeca UI Design Pattern Library - now titled the Endeca Discovery Pattern Library - is once again providing guidance and good practices on the design of discovery experiences.  Launched publicly in 2010 following several years of internal development and usage, the Endeca Pattern Library is a unique and valued source of industry-leading perspective on discovery - something I've come to appreciate directly through  fielding the consistent stream of inquiries about the library's status, and requests for its rapid return to public availability. Restoring the library as a public resource is only the first step!  For the next stage of the library's evolution, we plan to increase the scope of the guidance it offers beyond user interface design to the broader topic of discovery.  This could include patterns for architecture at the systems, user experience, and business levels; information and process models; analytical method and activity patterns for conducting discovery; and organizational and resource patterns for provisioning discovery capability in different settings.  We'd like guidance from the community on the kinds of patterns that are most valuable - so make sure to let us know. And we're also considering ways to increase the number of patterns the library offers, possibly by expanding the set of contributors and the authoring mechanisms. If you'd like to contribute, please get in touch. Here's the new address of the library: http://www.oracle.com/goto/EndecaDiscoveryPatterns And I should say 'Many thanks' to the UXDirect team and all the others within the Oracle family who helped - literally - keep the library alive, and restore it as a public resource.

• Were the first assemblers written in machine code?

  - by The111

  I am reading the book The Elements of Computing Systems: Building a Modern Computer from First Principles, which contains projects encompassing the build of a computer from boolean gates all the way to high level applications (in that order). The current project I'm working on is writing an assembler using a high level language of my choice, to translate from Hack assembly code to Hack machine code (Hack is the name of the hardware platform built in the previous chapters). Although the hardware has all been built in a simulator, I have tried to pretend that I am really constructing each level using only the tools available to me at that point in the real process. That said, it got me thinking. Using a high level language to write my assembler is certainly convenient, but for the very first assembler ever written (i.e. in history), wouldn't it need to be written in machine code, since that's all that existed at the time? And a correlated question... how about today? If a brand new CPU architecture comes out, with a brand new instruction set, and a brand new assembly syntax, how would the assembler be constructed? I'm assuming you could still use an existing high level language to generate binaries for the assembler program, since if you know the syntax of both the assembly and machine languages for your new platform, then the task of writing the assembler is really just a text analysis task and is not inherently related to that platform (i.e. needing to be written in that platform's machine language)... which is the very reason I am able to "cheat" while writing my Hack assembler in 2012, and use some preexisting high level language to help me out.

• How to get Autocad working with Wine?

  - by gabriel

  I am trying 3 years now installing Autocad,*3ds Max* and Revit architecture on Ubuntu with wine! Every year I am very optimistic 'cause I see the new wine versions already improved. So, now I am starting again in a clean Ubuntu installation to install Autocad 2013 with wine 1.4. I am not trying to have an answer only for me, but I want this community to try and finally we can achieve that! The winetricks have already net framework 4 to install which is the reason I have not already ran to the past Autocad. So, I would like to remove completely my windows 7 partition from my pc and go on a linux machine without loosing the powerfull architectural programms.I know all about Blender and staff so I just want you to help find a solution on that, because I know there is a solution! Maybe I will have to learn all the c++ or python etc. But I am sure that a solution can come with the help of all of us! Any suggestion about this problem will be very nice and helpfull.

• Should I pick up a functional programming language?

  - by Statement

  I have recently been more concerned about the way I write my code. After reading a few books on design patterns (and overzealous implementation of them, I'm sure) I have shifted my thinking greatly toward encapsulating that which change. I tend to notice that I write less interfaces and more method-oriented code, where I love to spruce life into old classes with predicates, actions and other delegate tasks. I tend to think that it's often the actions that change, so I encapsulate those. I even often, although not always, break down interfaces to a single method, and then I prefer to use a delegate for the task instead of forcing client code to create a new class. So I guess it then hit me. Should I be doing functional programming instead? Edit: I may have a misconception about functional programming. Currently my language of choice is C#, and I come from a C++ background. I work as a game developer but I am currently unemployed. I have a great passion for architecture. My virtues are clean, flexible, reusable and maintainable code. I don't know if I have been poisoned by these ways or if it is for the better. Am I having a refactoring fever or should I move on? I understand this might be a question about "use the right tool for the job", but I'd like to hear your thoughts. Should I pick up a functional language? One of my fear factors is to leave the comfort of Visual Studio.

• How to get initial API right using TDD?

  - by Vytautas Mackonis

  This might be a rather silly question as I am at my first attempts at TDD. I loved the sense of confidence it brings and generally better structure of my code but when I started to apply it on something bigger than one-class toy examples, I ran into difficulties. Suppose, you are writing a library of sorts. You know what it has to do, you know a general way of how it is supposed to be implemented (architecture wise), but you keep "discovering" that you need to make changes to your public API as you code. Perhaps you need to transform this private method into strategy pattern (and now need to pass a mocked strategy in your tests), perhaps you misplaced a responsibility here and there and split an existing class. When you are improving upon existing code, TDD seems a really good fit, but when you are writing everything from scratch, the API you write tests for is a bit "blurry" unless you do a big design up front. What do you do when you already have 30 tests on the method that had its signature (and for that part, behavior) changed? That is a lot of tests to change once they add up.

• Desktop Applications Versus Web Applications

  Up until the advent of the internet programmers really only developed one type of application used by end-users.  This type of application was called a desktop application. As the name implies, these applications ran strictly from a desktop computer, and were limited by the resources available to the computer. Initially, this type of applications did not need resources outside of the scope of the computer in which they installed. The problem with this type of application is that if multiple end-users need to access the same desktop application, then the application must be installed on the end-user’s computer. In this age of software development security was not as big of a concern as it is today with other types of applications. This is primarily due to the fact that an end-user must have access to the computer where the software is installed in order for them to access the application. In addition, developers could also password protect the application just in case an authorized end-user was able to gain access to the computer. With the birth of the internet a second form of application emerged because developers were trying to solve inherent issues with the preexisting desktop application. One of the solutions to overcome some of the short comings of desktop applications is the web application. Web applications are hosted on a centralized server and clients only need to have network access and a web browser in order to access the application. Because a web application can be installed on a remote server it removes the need for individual installations of the same application on each end-user’s computer.  The main benefits to an application being hosted on a server is increased accessibility to the application due to the fact that nothing has to be installed on a desktop computer for an end-user to be able to access the application. In addition, web applications are much easier to maintain because any change to the application is applied on the server and is inherently applied to any end-user trying to use the application. This removes the time needed to install and maintain individual installations of a desktop application. However with the increased accessibility there are additional costs that are incurred compared to a desktop application because of the additional cost and maintenance of a server hosting the application. Typically, after a desktop application is purchased there are no additional reoccurring fees associated with the application.  When developing a web based application there are additional considerations that must be addressed compared to a desktop application. The added benefit of increased accessibility also now adds a new failure point when trying to gain access to an application. An end-user now must have network connectivity in order to access the application. This issue is not a concern for desktop applications because there resources are typically bound to the computer in which they run. Since the availability of an application is increased with the use of the client-server model in a web based application, additional security concerns now come in to play. As stated before a, desktop application is bound to the accessibility of the end-user to the computer that the application is installed. This is not the case with web based applications because they potentially could have access from anywhere with the proper internet/network connection. Additional security steps are required to insure the integrity of the application and its data. Examples of these steps include and are not limited to the following: Restricted/Password Areas This form of security is used when specific information can only be accessed by end-users based on a set of accessibility rules. IP Restrictions This form of security is used when only specific locations need to access an application. This form of security is applied from within the web server or a firewall. Network Restrictions (Firewalls) This form of security is used to contain access to an application within a specific sub set of a network. Data Encryption This form of security is used transform personally identifiable information in to something unreadable so that it can be stored for future use. Encrypted Protocols (HTTPS) This form of security is used to prevent others from reading messages being sent between applications over a network.

• Integrating with Oracle Fusion Applications: Discovering Integration Artifacts

  - by Lionel Dubreuil

  Oracle Enterprise Repository serves as the core element to the Oracle SOA Governance solution. An industry-leading metadata repository, Oracle Enterprise Repository provides a solid foundation for delivering governance throughout the service-oriented architecture (SOA) lifecycle by acting as the single source of truth for information surrounding SOA assets and their dependencies. For Fusion Applications, the use of OER has been extended to include other integration asset types such as interface tables and other technical information such as data models, tables, views, lookups, profile options, et cetera. E-Business Suite users familiar with iRepository or eTRM will recognize the functionality in Fusion Applications OER. Oracle Enterprise Repository for Fusion Applications provides a common catalog of technical information, searchable using many different mechanisms. Customers can locate technical information by the name, description or keyword of the information they are looking for. They can also search by the type of asset they are trying to locate and/or where the asset sits in the product taxonomy. They can also see the how the asset dances in the choreography of some illustrative co-existence scenarios. These scenarios are laid out as both functional flow diagrams as well as technical interaction diagrams. Rajesh Raheja, software architect at Oracle, has recently posted an article on this topic: visibility and control are the key tenets to SOA governance, and the first step in integrating with Oracle Fusion Applications is to find out what are the integration options available. Oracle Enterprise Repository, an industry-leading metadata repository, provides this visibility. You can find his full blog post here.

• Sprinkle Some Magik on that Java Virtual Machine

  - by Jim Connors

  GE Energy, through its Smallworld subsidiary, has been providing geospatial software solutions to the utility and telco markets for over 20 years.  One of the fundamental building blocks of their technology is a dynamically-typed object oriented programming language called Magik.  Like Java, Magik source code is compiled down to bytecodes that run on a virtual machine -- in this case the Magik Virtual Machine. Throughout the years, GE has invested considerable engineering talent in the support and maintenance of this virtual machine.  At the same time vast energy and resources have been invested in the Java Virtual Machine. The question for GE has been whether to continue to make that investment on its own or to leverage massive effort provided by the Java community? Utilizing the Java Virtual Machine instead of maintaining its own virtual machine would give GE more opportunity to focus on application solutions.   At last count, there are dozens, perhaps hundreds of examples of programming languages that have been hosted atop the Java Virtual Machine.  Prior to the release of Java 7, that effort, although certainly possible, was generally less than optimal for languages like Magik because of its dynamic nature.  Java, as a statically typed language had little use for this capability.  In the quest to be a more universal virtual machine, Java 7, via JSR-292, introduced a new bytecode called invokedynamic.  In short, invokedynamic affords a more flexible method call mechanism needed by dynamic languages like Magik. With this new capability GE Energy has succeeded in hosting their Magik environment on top of the Java Virtual Machine.  So you may ask, why would GE wish to do such a thing?  The benefits are many: Competitors to GE Energy claimed that the Magik environment was proprietary.  By utilizing the Java Virtual Machine, that argument gets put to bed.  JVM development is done in open source, where contributions are made world-wide by all types of organizations and individuals. The unprecedented wealth of class libraries and applications written for the Java platform are now opened up to Magik/JVM platform as first class citizens. In addition, the Magik/JVM solution vastly increases the developer pool to include the 9 million Java developers -- the largest developer community on the planet. Applications running on the JVM showed substantial performance gains, in some cases as much as a 5x speed up over the original Magik platform. Legacy Magik applications can still run on the original platform.  They can be seamlessly migrated to run on the JVM by simply recompiling the source code. GE can now leverage the huge Java community.  Undeniably the best virtual machine ever created, hundreds if not thousands of world class developers continually improve, poke, prod and scrutinize all aspects of the Java platform.  As enhancements are made, GE automatically gains access to these. As Magik has little in the way of support for multi-threading, GE will benefit from current and future Java offerings (e.g. lambda expressions) that aim to further facilitate multi-core/multi-threaded application development. As the JVM is available for many more platforms, it broadens the reach of Magik, including the potential to run on a class devices never envisioned just a few short years ago.  For example, Java SE compatible runtime environments are available for popular embedded ARM/Intel/PowerPC configurations that could theoretically host this software too. As compared to other JVM language projects, the Magik integration differs in that it represents a serious commercial entity betting a sizable part of its business on the success of this effort.  Expect to see announcements not only from General Electric, but other organizations as they realize the benefits of utilizing the Java Virtual Machine.

• New Working Environment Starting November

  - by Jenson

  Normal 0 false false false EN-GB X-NONE X-NONE MicrosoftInternetExplorer4 This is actually a post dated update. After I’ve been working in the private sectors for so many years (the 2 years when I was working as IT trainer in a secondary school is not counted, as I was working under a contract with a private IT training agency), I’ve decided to try my luck into public sector. And fortunately, I passed the interview and I was offered a position of Web Administrator in a government statutory board, that’s Agency for Science, Technology and Research (of Singapore). During my previous employment with a Japanese MNC (multinational company), it was a totally new environment for me, as I had never worked for a Japanese company before, but the first time I work for Japanese company also gave me the very first nightmare I have with them, and vowed not to work for them anymore, and any other Japanese companies. No doubt I have freedom of choosing the tools and methods I wish to use for the projects, but the project management is simply too messy and out of order. And a lot of time, I don’t find that everyone is working as a team, more like achieving their own goals. Accountability for project is not shared, all lumped onto the shoulders of the developer in charge (they called it Software Engineer). I was working on a windows based .NET project, which I already voiced out that it’s not manageable by just 1 software engineer, but it seems like nobody cares, even the one who propose the solution to customer doesn’t care much. What he cares is whether you deliver the project on time so that he can please his customer and the senior management of his good work. Too many stories to tell, and I just simple doesn’t want to talk too much on this as it has already became the past to me. With my new title with the government agency, I hope to contribute my best to them, while learning as much as I can. I will share whatever I can on technologies, methodologies, and etc whichever I’m allowed and permitted to (of course, for those non-work-related stuff, I would be glad to share with you without much hesitation). Thank you! /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

• New way of integrating Openfeint in Cocos2d-x 0.12.0

  - by Ef Es

  I am trying to implement OpenFeint for Android in my cocos2d-x project. My approach so far has been creating a button that calls a static java method in class Bridge using jnihelper functions (jnihelper only accepts statics). Bridge has one singleton attribute of type OFAndroid, that is the class dynamically calling the Openfeint Api methods, and every method in the bridge just forwards it to the OFAndroid object. What I am trying to do now is to initialize the openfeint libraries in the main java class that is the one calling the static C++ libraries. My problem right now is that the initializing function void com.openfeint.api.OpenFeint.initialize(Context ctx, OpenFeintSettings settings, OpenFeintDelegate delegate) is not accepting the context parameter that I am giving him, which is a "this" reference to the main class. Main class extends from Cocos2dxActivity but I don't have any other that extends from Application. Any suggestions on fixing it or how to improve the architecture? EDIT: I am trying a new solution. Make the bridge class into an Application child, is called from Main object, initializes OpenFeint when created and it can call the OpenFeint functions instead of needing an additional class. The problem is I still get the error. 03-30 14:39:22.661: E/AndroidRuntime(9029): Caused by: java.lang.NullPointerException 03-30 14:39:22.661: E/AndroidRuntime(9029): at android.content.ContextWrapper.getPackageManager(ContextWrapper.java:85) 03-30 14:39:22.661: E/AndroidRuntime(9029): at com.openfeint.internal.OpenFeintInternal.validateManifest(OpenFeintInternal.java:885) 03-30 14:39:22.661: E/AndroidRuntime(9029): at com.openfeint.internal.OpenFeintInternal.initializeWithoutLoggingIn(OpenFeintInternal.java:829) 03-30 14:39:22.661: E/AndroidRuntime(9029): at com.openfeint.internal.OpenFeintInternal.initialize(OpenFeintInternal.java:852) 03-30 14:39:22.661: E/AndroidRuntime(9029): at com.openfeint.api.OpenFeint.initialize(OpenFeint.java:47) 03-30 14:39:22.661: E/AndroidRuntime(9029): at nurogames.fastfish.NuroFeint.onCreate(NuroFeint.java:23) 03-30 14:39:22.661: E/AndroidRuntime(9029): at nurogames.fastfish.FastFish.onCreate(FastFish.java:47) 03-30 14:39:22.661: E/AndroidRuntime(9029): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1069) 03-30 14:39:22.661: E/AndroidRuntime(9029): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2751)

• Determinism in multiplayer simulation with Box2D, and single computer

  - by Jake

  I wrote a small test car driving multiplayer game with Box2D using TCP server-client communcations. I ran 1 instance of server.exe and 2 instance of client.exe on the same machine that I code and compile the executables. I type inputs (WASD for a simple car movement) into one of the 2 clients and I can get both clients to update the simulation. There are 2 cars in the simulation. As long as the cars do not collide, I get the same identical output on both client.exe. I can run the car(s) around for as long as I could they still update the same. However, if I start to collide the cars, very quickly they go out of sync. My tools: Windows 7, C++, MSVS 2010, Box2D, freeGlut. My Psuedocode: // client.exe void timer(int value) { tcpServer.send(my_inputs); foreach(i = player including myself) inputs[i] = tcpServer.receive(); foreach(i = player including myself) players[i].process(inputs[i]); myb2World.step(33, 8, 6); // Box2D world step simulation foreach(i = player including myself) renderer.render(player[i]); glutTimerFunc(33, timer, 0); } // server.exe void serviceloop { while(all clients alive) { foreach(c = clients) tcpClients[c].receive(&inputs[c]); // send input of each client to all clients foreach(source = clients) { foreach(dest = clients) { tcpClients[dest].send(inputs[source]); } } } } I have read all over the internet and SE the following claims (paraphrased): Box2D is deterministic as long as floating point architecture/implementation is the same. (For any deterministic engine) Determinism is gauranteed if playback of recorded inputs is on the same machine with exe compiled using same compiler and machine. Additionally my server.exe and client.exe gameloop is single thread with blocking socket calls and fixed time step. Question: Can anyone explain what I did wrong to get different Box2D output?

• Using unordered_multimap as entity and component storage

  - by natebot13

  The Setup I've made a few games (more like animations) using the Object Oriented method with base classes for objects that extend them, and objects that extend those, and found I couldn't wrap my head around expanding that system to larger game ideas. So I did some research and discovered the Entity-Component system of designing games. I really like the idea, and thoroughly understood the usefulness of it after reading Byte54's perfect answer here: Role of systems in entity systems architecture. With that said, I have decided to create my current game idea using the described Entity-Component system. Having basic knowledge of C++, and SFML, I would like to implement the backbone of this entity component system using an unordered_multimap without classes for the entities themselves. Here's the idea: An unordered_mulitmap stores entity IDs as the lookup term, while the value is an inherited Component object. Examlpe: ____________________________ |ID |Component | ---------------------------- |0 |Movable | |0 |Accelable | |0 |Renderable | |1 |Movable | |1 |Renderable | |2 |Renderable | ---------------------------- So, according to this map of objects, the entity with ID 0 has three components: Movable, Accelable, and Renderable. These component objects store the entity specific data, such as the location, the acceleration, and render flags. The entity is simply and ID, with the components attached to that ID describing its attributes. Problem I want to store the component objects within the map, allowing the map have full ownership of the components. The problem I'm having, is I don't quite understand enough about pointers, shared pointers, and references in order to get that set up. How can I go about initializing these components, with their various member variables, within the unordered_multimap? Can the base component class take on the member variables of its child classes, when defining the map as unordered_multimap<int, component>? Requirements I need a system to be able to grab an entity, with all of its' attached components, and access members from the components in order to do the necessary calculations and reassignments for position, velocity, etc. Need a clarification? Post a comment with your concerns and I will gladly edit or comment back! Thanks in advance! natebot13

• The Power to Control Power

  - by speakjava

  I'm currently working on a number of projects using embedded Java on the Raspberry Pi and Beagle Board.  These are nice and small, so don't take up much room on my desk as you can see in this picture. As you can also see I have power and network connections emerging from under my desk.  One of the (admittedly very minor) drawbacks of these systems is that they have no on/off switch.  Instead you insert or remove the power connector (USB for the RasPi, a barrel connector for the Beagle).  For the Beagle Board this can potentially be an issue; with the micro-SD card located right next to the connector it has been known for people to eject the card when trying to power off the board, which can be quite serious for the hardware. The alternative is obviously to leave the boards plugged in and then disconnect the power from the outlet.  Simple enough, but a picture of underneath my desk shows that this is not the ideal situation either. This made me think that it would be great if I could have some way of controlling a mains voltage outlet using a remote switch or, even better, from software via a USB connector.  A search revealed not much that fit my requirements, and anything that was close seemed very expensive.  Obviously the only way to solve this was to build my own.Here's my solution.  I decided my system would support both control mechanisms (remote physical switch and USB computer control) and be modular in its design for optimum flexibility.  I did a bit of searching and found a company in Hong Kong that were offering solid state relays for 99p plus shipping (£2.99, but still made the total price very reasonable).  These would handle up to 380V AC on the output side so more than capable of coping with the UK 240V supply.  The other great thing was that being solid state, the input would work with a range of 3-32V and required a very low current of 7.5mA at 12V.  For the USB control an Arduino board seemed the obvious low-cost and simple choice.  Given the current requirments of the relay, the Arduino would not require the additional power supply and could be powered just from the USB.Having secured the relays I popped down to Homebase for a couple of 13A sockets, RS for a box and an Arduino and Maplin for a toggle switch.  The circuit is pretty straightforward, as shown in the diagram (only one output is shown to make it as simple as possible).  Originally I used a 2 pole toggle switch to select the remote switch or USB control by switching the negative connections of the low voltage side.  Unfortunately, the resistance between the digital pins of the Arduino board was not high enough, so when using one of the remote switches it would turn on both of the outlets.  I changed to a 4 pole switch and isolated both positive and negative connections. IMPORTANT NOTE: If you want to follow my design, please be aware that it requires working with mains voltages.  If you are at all concerned with your ability to do this please consult a qualified electrician to help you.It was a tight fit, especially getting the Arduino in, but in the end it all worked.  The completed box is shown in the photos. The remote switch was pretty simple just requiring the squeezing of two rocker switches and a 9V battery into the small RS supplied box.  I repurposed a standard stereo cable with phono plugs to connect the switch box to the mains outlets.  I chopped off one set of plugs and wired it to the rocker switches.  The photo shows the RasPi and the Beagle board now controllable from the switch box on the desk. I've tested the Arduino side of things and this works fine.  Next I need to write some software to provide an interface for control of the outlets.  I'm thinking a JavaFX GUI would be in keeping with the total overkill style of this project.
