  • AndEngine GLES2 - getting Black screen on emulator 4.1

    - by dizworld.com
    I'm new in andengine . I create following code public class MainActivity extends BaseGameActivity { static final int CAMERA_WIDTH = 800; static final int CAMERA_HEIGHT = 480; public Font mFont; public Camera mCamera; //A reference to the current scene public Scene mCurrentScene; public static BaseActivity instance; public EngineOptions onCreateEngineOptions() { instance = this; mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT); return new EngineOptions(true, ScreenOrientation.LANDSCAPE_SENSOR, new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), mCamera); } @Override public void onCreateResources(OnCreateResourcesCallback arg0) throws Exception { mFont = FontFactory.create(this.getFontManager(),this.getTextureManager(), 256, 256,Typeface.create(Typeface.DEFAULT, Typeface.BOLD), 32); mFont.load(); } @Override public void onCreateScene(OnCreateSceneCallback arg0) throws Exception { mEngine.registerUpdateHandler(new FPSLogger()); mCurrentScene = new Scene(); Log.v("Scene","enter"); mCurrentScene.setBackground(new Background(0.09804f, 0.7274f, 0.8f)); // return mCurrentScene; } @Override public void onPopulateScene(Scene arg0, OnPopulateSceneCallback arg1) throws Exception { // TODO Auto-generated method stub } } I got code on sites there is returning scene but in AndEngine GLES2 in method onCreateScene() there is no return scene ... so my First run is BLACK .. any suggestion :)

  • How to sync client and server at the first frame

    - by wheelinlight
    I'm making a game where an authoritative server sends information to all clients about states and positions for objects in a 3d world. The player can control his character by clicking on the screen to set a destination for the character, much like in the Diablo series. I've read most information I can find online about interpolation, reconciliation, and general networking architecture (Valve's for instance). I think I understand everything but one thing seems to be missing in every article I read. Let say we have an interpolation delay of 100ms, server tickrate=50ms, latency=200ms; How do I know when 100ms has past on the client? If the server sends the first update on t=0, can I assume it arrives at t=200, therefore assuming that all packets takes the same amount of time to reach the client? What if the first packet arrives a little quick, for instance at t=150. I would then be starting the client with t=150 and at t=250 it will think it has past 100ms since its connect to the server when it in fact only 50ms has past. Hopefully the above paragraph is understandable. The summarized question would be: How do I know at what tick to start simulating the client? EDIT: This is how I ended up doing it: The client keeps a clock (approximately) in sync with the server. The client then simulates the world at simulationTime = syncedTime - avg(RTT)/2 - interpolationTime The round-trip time can fluctuate so therefore I average it out over time. By only keeping the most recent values when calculating the average I hope to adapt to more permanent changes in latency. It's still to early to draw any conclusion. I'm currently simulating bad network connections, but it's looking good so far. Anyone see any possible problems?

  • Select firefox search result

    - by Nicolas C.
    I am working on a daily basis on a web application with very large menus. Also doing lots of other Excel manipulations, copy and pasting, etc., I am quite fond of keyboard shortcuts as much faster than using the mouse to point, double-click and then going back to my keyboard etc. Hence, my question is quite simple, does anyone know if there is any shortcut under Firefox which would let me actually select (and not highlight) in my web page the search result so that I can for instance do the following manipulation sequence? [Ctrl]+[F] type the search string, for instance 'regional_unit' the missing shortcut to actually select in my page the string which is currently highlighted thanks to the search feature of FF [Space] or [Enter] key to activate the web element which in my case would systematically correspond to a link or button, etc. May be there would be an addon replacing the default search feature, I don't know... I tried to look over the internet but with the words I am using for this investigation, I do not get relevant search results under Google :(. Thanks a lot

  • How do you avoid name similarities between your classes and the native ones?

    - by Oscar
    I just ran into an "interesting problem", which I would like your opinion about: I am developing a system and for many reasons (meaning: abstraction, technology independence, etc) we create our own types for exchanging information. For instance: if there is a method which is called SendEmail and is invoked by the business logic, it way have a parameter of type OurCompany.EMailMessage, which is an object which is completely technology independent and contains only "business relevant data" (for instance, no information abut head encoding). Inside the SendEmail function, we get this information from our EMailMEssage object and create a MailMessage (this one is technolgy specific) object so it can be sent over the network. As you can already notice, our class has a very similar name to the "native" language class. The problem is: this is exactly what they are, email messages, so it is hard to find another meaningful name for them. Do you have this problem often? How do you manage it? Edit: @mgkrebbs just commented about using fully qualified names. This is our current approach, but a little bit too verbose, IMHO. I would like something cleaner, if possible.

  • MSSQL: Choice of service accounts

    - by Troels Arvin
    When installing MS SQL Server 2008, one needs to associate a service account with the installation (possibly even several accounts, one for the SQL Server Agent, one for Analysis Services, ..., but let's leave that for the case of simplicity). The service account may be local account, or a Windows domain account. If a domain account is used: Can MSSQL start, if connectivity to the domain controllers is temporarily down? If the answer is yes: Should each DBMS instance on each server have a separate account, or does it make sense to use a particular "MSSQL" domain account on all MSSQL-installations in the organization? If separate accounts are used for each instance on each server: Does it make sense to create a special MSSQL security group in the domain and place all the MSSQL service accounts in that group, perhaps to ease replication, etc? Is there a common, generally accepted naming convention for MSSQL service account(s)?

  • Automating the Backup of a SQL Server 2008 Express Database

    - by JaydPage
    Steps Involved: 1) Create a Database Backup Script. 2) Create a Scheduled Task To Run the Backup Script. 1 Create a Database Backup Script. a) Download and install SQL Server Management Studio. This is a free tool available on the Microsoft website. b) Once Management Studio is installed launch it and connect to the SQL server instance that contains the database that you want to back up. c) Right click on the database and then in the menu choose Tasks -> Back up... d) This will open up a window where you can choose your backup options, once you are happy with the options click on the "Script" button near the top and select the "Script Action to File" option. e) Save the File. 2 Create a Schedule Task to Run the Backup Script a) Open up Windows Task Scheduler. b) Create a new Task using the wizard, when asked to select a program browse to C:\Program Files\Microsoft SQL Server\100\Tools\binn\SQLCMD.exe c) There are 2 arguments that need to be set: -S \SERVER_INSTANCE_NAME  -i "PATH_OF_SQLBACKUP_SCRIPT" where SERVER_INSTANCE_NAME  is the name of the instance of SQL server that contains your database e.g. (local) and PATH_OF_SQLBACKUP_SCRIPT is the path of your backup script e.g. "C:\Program Files\Microsoft SQL Server\DatastoreBackup.sql" d) Adjust the task to run at the desired times and you are done.

  • How do you keep up with Nagios/Capistrano configs when using EC2?

    - by imaginative
    I use Amazon EC2 for my mobile app. Depending on load of the application at a given time, I might spawn new instances and then take them down when load is lower to save costs. How does one keep up with Nagios configurations for such a dynamic environment? When one deals with managed hardware, configuration files are predictable. In this case Nagios, Capistrano and a bunch of other configuration files would need to be added. Capistrano needs to know where to deploy a new build to for an app server. Nagios needs to know to remove an existing instance or add a new instance for monitoring. Nagios also needs to know if a node was intentionally taken down or if the host is down due to error. How is this done with the wonderful world of VPS/dynamic instances?

  • For an ORM supporting data validation, should constraints be enforced in the database as well?

    - by Ramnique Singh
    I have always applied constraints at the database level in addition to my (ActiveRecord) models. But I've been wondering if this is really required? A little background I recently had to unit test a basic automated timestamp generation method for a model. Normally, the test would create an instance of the model and save it without validation. But there are other required fields that aren't nullable at the in the table definition, meaning I cant save the instance even if I skip the ActiveRecord validation. So I'm thinking if I should remove such constraints from the db itself, and let the ORM handle them? Possible advantages if I skip constraints in db, imo - Can modify a validation rule in the model, without having to migrate the database. Can skip validation in testing. Possible disadvantage? If its possible that ORM validation fails or is bypassed, howsoever, the database does not check for constraints. What do you think? EDIT In this case, I'm using the Yii Framework, which generates the model from the database, hence database rules are generated also (though I could always write them post-generation myself too).

  • Enable a program in Windows to run multiple times?

    - by user135490
    I've got this legacy software that only allows you to run one copy at a time, it detects that you have another session opened and it won't allow you to open a second instance. The problem is this is a cpu intensive program and it only use a single core. Is there any hacks or tweaks so I can trick it and open more than one instance? This would allow me to retire about 5 servers... I'm using Windows 2008 R2. I had to use cff explorer to enable the use more than 2GB RAM as the program crashes when it tries to use more than 2GB.

  • Is there any way to prevent a Mac from creating dot underscore files?

    - by SoaperGEM
    At work we're letting one of our very tech savvy clients actually help out a little with a few development projects specific to him. However, he uses his own personal Macbook, and as he edits files on our (Windows) networks, his Macbook always creates a bunch of unnecessary meta files that we end up deleting later. For instance, it creates a file called .DS_Store in any directory he opens, as well as "dot underscore" files for each file he edits. So for instance, if he's editing a file called "Main.php", his Macbook will create another file called "._Main.php". I know there are ways to prevent creation of .DS_Store files, but none about how to prevent creation of these hidden files prefixed with dot underscore. Is there any way to turn that off on Macs? Any way to prevent it from creating those files in the first place?

  • Encapsulating code in F# (Part 2)

    - by MarkPearl
    In part one of this series I showed an example of encapsulation within a local definition. This is useful to know so that you are aware of the scope of value holders etc. but what I am more interested in is encapsulation with regards to generating useful F# code libraries in .Net, this is done by using Namespaces and Modules. Lets have a look at some C# code first… using System; namespace EncapsulationNS { public class EncapsulationCLS { public static void TestMethod() { Console.WriteLine("Hello"); } } } Pretty simple stuff… now the F# equivalent…. namespace EncapsulationNS module EncapsulationMDL = let TestFunction = System.Console.WriteLine("Hello") ()   Even easier… lets look at some specifics about F# namespaces… Namespaces are open. meaning you can have multiple source files and assemblies can contribute to the same namespace. So, Namespaces are a great way to group modules together, so the question needs to be asked, what role do modules play. For me, the F# module is in many ways similar to the vb6 days of modules. In vb6 modules were separate files and simply allowed us to group certain methods together. I find it easier to visualize F# modules this way than to compare them to the C# classes. However that being said one is not restricted to one module per file – there is flexibility to have multiple modules in one code file however with my limited F# experience I would still recommend using the file as the standard level of separating modules as it is very easy to then find your way around a solution. An important note about interop with F# and other .Net languages. I wrote a blog post a while back about a very basic F# to C# interop. If I were to reference an F# library in a C# project (for instance ‘TestFunction’), in C# it would show this method as a static method call, meaning I would not have to instantiate an instance of the module.

  • How to disable Spotlight content indexing in Mac OS

    - by o.v.
    From Windows experience, I could always elect Live search to only index file names not their content. Is this something that can be done with Spotlight on a Mac? It used to index absolutely everything, for instance it would return a bunch of video files for any obscure character combination typed into the search field. Right now I've disabled Spotlight entirely as per this answer, but it seems to have disabled searching altogether. For instance, Finder is yet to locate any .pdf files in a small directory as I'm typing this question (unlike windows search which would still be able to work even with indexing disabled) Alternatively, if there is any way (including a trusted third-party app) that will index file names and metadata e.g. ID3 tags that would likely be the preferred option.

  • Windows 7 file explorer preview window and password protected word documents

    - by Carbonara
    When using the Windows 7 Explorer with the preview pane open you get a little preview of a file when you click on it. This includes Word, Excel spreadsheets, etc. My problem is if the Word document is password protected. Clicking on it in Explorer automatically asks for the password to display its preview. It does this if you single or double clicking on it. You then get an empty Word instance running (which allows it to display the preview) and another instance of Word with your actual file and you're asked for the password twice in total. This is annoying and untidy. Is there a way of stopping the preview pane from wanting to display password protected documents and thus not asking for the password to display a preview?

  • Virtual Box - not filling entire screen

    - by jdavis
    I am new to VirtualBox and am trying to set up an instance of Windows 7 64. I have the virtual machine instance running with Windows 7 now installed, but it only fills up a small portion of my screen. Even when I go full screen, the window stays the same size and the rest of the screen is filled with gray space. I have installed VirtualBox Guest Additions, which allowed me to go from a resolution of 800x600 to 1024x768, but this still isn't satisfactory as my laptop display is 1600x900. Any help on this would be most appreciated. Thanks.

  • How do I move *all* the installed software on my EC2 isntance to EBS?

    - by drhyde
    I got started with Eric Hammond's great article over at http://aws.amazon.com/articles/1663 where he goes through installing MySQL and configuring it to use EBS. I got that going. I also have a lot of other stuff installed on that EC2 instance: Rails, a bunch of gems, Nginx+Passenger and so on - my understanding is that unless I explicitly configure it to use EBS, all of this sits on the EC2 instance's ephemeral storage - right? How can I move all the software I have installed to EBS - or better yet how can I set up such that going forward also any new gems etc that I install also go to the EBS volume?

  • Spring Cleaning

    - by Tim Dexter
    I recently got a shiny new laptop; moving my shiz from old to new, was not the nightmare it used to be. I have gotten into the habit of using a second hard drive in the media bay where the CDROM normally sits. That drive contains my life's work with BIP. I can pull it out and plug it into another machine very easily. I have been sorting through some old directories and files, archiving some, sharing others with colleagues. For instance, a little dated but if you were looking for a list of Publisher reports available in EBS R12.1, here it is. Im trying to track down a more recent R12 instance and will re-post the document. I also found another gem; its a little out there in terms of usefulness but Im sharing it none the less. You can embed, locally or remotely reference SVG graphics (in XML format) and bring the images into the BIP outputs. Template and sample data here. A nice set of templates showing page number control and page suppression - they will need some explanation, so I'll save them for another post. The list goes on but I'll save them for later. Back to the clean up!

  • Windows 7 - Move open programs more freely on the taskbar

    - by SalamiArmi
    When I used Windows XP last year, I had a program called Taskix which let me move the tabs in the taskbar around for programs in any order I wanted. Now that I have Windows 7, a similar function comes built into the operating system - however, it isn't as flexible as Taskix was in XP. Theoretical situation: 1. Open a folder named #1 2. In folder #1, open an instance of a program 3. Open a folder named #2 4. In folder #2, open an instance of the same program that was opened in step 2. After doing this, I will have (in order, on the taskbar) 2 folders open and 2 instances of the programs open. My question really is: Is there any way to fight this automatic ordering of tabs on the taskbar? A registry hack or something would be best, but if there's a third party program out there, that would be nice to know about. Thanks!

  • Extensions disappear when I close and open Google Chrome

    - by PavanM
    I am running the latest version of Google Chrome 23.0.1271.97 (Official Build 171054) m on Windows 7. Any new extension I install simply disappears(not disabled, total disappearance) once I close and re-start google chrome. This is not happening to one of my old extension. It stays there across chrome re-starts. I tried everything google help suggested- I created new user profile by renaming the Defaults folder I checked for any permission change that the extensions might have undergone. This is not the case. I am not running in developer mode. This happens when I close ALL instances of google chrome. Even if one instance of chrome is running, this doesn't happen. But I cant have an instance of Google Chrome always running :( I even reported the issue to Google Chrome team to no avail and new.crbug.com is offline. And I skimmed through many threads opened for the same issue only to find souls like me. SE is my last resort :)

  • Wordpress serving PHP but not CSS or JS

    - by Jason
    I'm trying to set up an Amazon EC2 instance to run a Django app and a WP instance side by side, differing only by the incoming URL. Initially, accessing the site via mysite.com/wordpress worked, but I also needed to catch the incoming requests from a subdomain address blog.mysite.com. To do that, I created a default file in /etc/apache2/sites-enabled and included two virtualhost directives, one of which was <VirtualHost *:80> ServerName www.blog.mysite.com <Directory /var/www/wordpress> Order deny,allow Allow from all </Directory> </VirtualHost> This created some errors with the other virtualhost, so I restored the default 000-default file configuration and restarted. Now, accessing mysite.com/wordpress takes forever, and even then the CSS and JS files are not loading. Iside the Firebug Net tab, I can see the HTML response, but the CSS and JS files are not loading at all. What happened here?

  • Windows Server R2 Task Scheduler - Open Programs On Startup

    - by Markive
    I want Fiddler and some other programs to run on startup, so it's there and running every time I bring up an instance of my test server on EC2. There's a few questions about running scripts on Startup with Task Scheduler, but this needs to work slightly differently. I have set this up to run on startup but when I RDP into the server I can see Fiddler is running in Task Manager (so I can't manually run a second instance of the program), but it's not viewable on the task bar? So I can't actually see the interface? Here's my setup: General Tab Running with highest privileges Run whether user is logged on or not Configure for Windows 2008 server R2 Triggers Tab At startup Others are obvious and defaults.. What am I doing wrong?

  • SQL server could not connect: Lacked Sufficient Buffer Space...

    - by chumad
    I recently moved my app to a new server - the app is written in c# against the 3.5 framework. The hardware is faster but the OS is the same (Win Server 2003). No new software is running. On the prior hardware the app would run for months with no problems. Now, in this new install, I get the following error after about 3 days, and the only way to fix it is to reboot: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.) I have yet to find a service I can even shut down to make it work. Anyone had this before and know a solution?

  • REST API wrapper - class design for 'lite' object responses

    - by sasfrog
    I am writing a class library to serve as a managed .NET wrapper over a REST API. I'm very new to OOP, and this task is an ideal opportunity for me to learn some OOP concepts in a real-life situation that makes sense to me. Some of the key resources/objects that the API returns are returned with different levels of detail depending on whether the request is for a single instance, a list, or part of a "search all resources" response. This is obviously a good design for the REST API itself, so that full objects aren't returned (thus increasing the size of the response and therefore the time taken to respond) unless they're needed. So, to be clear: .../car/1234.json returns the full Car object for 1234, all its properties like colour, make, model, year, engine_size, etc. Let's call this full. .../cars.json returns a list of Car objects, but only with a subset of the properties returned by .../car/1234.json. Let's call this lite. ...search.json returns, among other things, a list of car objects, but with minimal properties (only ID, make and model). Let's call this lite-lite. I want to know what the pros and cons of each of the following possible designs are, and whether there is a better design that I haven't covered: Create a Car class that models the lite-lite properties, and then have each of the more detailed responses inherit and extend this class. Create separate CarFull, CarLite and CarLiteLite classes corresponding to each of the responses. Create a single Car class that contains (nullable?) properties for the full response, and create constructors for each of the responses which populate it to the extent possible (and maybe include a property that returns the response type from which the instance was created). I expect among other things there will be use cases for consumers of the wrapper where they will want to iterate through lists of Cars, regardless of which response type they were created from, such that the three response types can contribute to the same list. Happy to be pointed to good resources on this sort of thing, and/or even told the name of the concept I'm describing so I can better target my research.

  • Designing object oriented programming

    - by Pota Onasys
    Basically, I want to make api calls using an SDK I am writing. I have the following classes: Car CarData (stores input values needed to create a car like model, make, etc) Basically to create a car I do the following: [Car carWithData: cardata onSuccess: successHandler onError: errorHandler] that basically is a factory method that creates instance of Car after making an API call request and populating the new Car class with the response and passes that instance to the successHandler. So "Car" has the above static method to create that car, but also has non-static methods to edit, delete cars (which would make edit, delete API calls to the server) So when the Car create static method passes a new car to the successHandler by doing the following: successHandler([[Car alloc] initWithDictionary: dictionary) The success handler can go ahead and use that new car to do the following: [car update: cardata] [car delete] considering the new car object now has an ID for each car that it can pass to the update and delete API calls. My questions: Do I need a cardata object to store user inputs or can I store them in the car object that would also later store the response from all of the api calls? How can I improve this model? With regards to CarData, note that there might be different inputs for the different API calls. So create function might need to know model, make, etc, but find function might need to know the number of items to find, the limit, the start id, etc.

  • Could a singleton type replace static methods and classes?

    - by MKO
    In C# Static methods has long served a purpose allowing us to call them without instantiating classes. Only in later year have we became more aware of the problems of using static methods and classes. They can’t use interfaces They can’t use inheritance They are hard to test because you can’t make mocks and stubs Is there a better way ? Obviously we need to be able to access library methods without instantiated classes all the time otherwise our code would become pretty cluttered One possibly solution is to use a new keyword for an old concept: the singleton. Singleton’s are global instances of a class, since they are instances we can use them as we would normal classes. In order to make their use nice and practical we'd need some syntactic sugar however Say that the Math class would be of type singleton instead of an actual class. The actual class containing all the default methods for the Math singleton is DefaultMath, which implements the interface IMath. The singleton would be declared as singleton Math : IMath { public Math { this = new DefaultMath(); } } If we wanted to substitute our own class for all math operations we could make a new class MyMath that inherits DefaultMath, or we could just inherit from the interface IMath and create a whole new Class. To make our class the active Math class, you'd do a simple assignment Math = new MyMath(); and voilá! the next time we call Math.Floor it will call your method. Note that for a normal singleton we'd have to write something like Math.Instance.Floor but the compiler eliminates the need for the Instance property Another idea would be to be able to define a singletons as Lazy so they get instantiated only when they're first called, like lazy singleton Math : IMath What do you think, would it have been a better solution that static methods and classes? Is there any problems with this approach?

  • Solutions for "Maintenance Mode"

    - by Ka Lyse
    Given a web application running across 10+ servers, what techniques have you put in place for doing things like altering the state of your website so that you can implement certain features. For instance, you might want to: Restrict Logins/Disable Certain Features Turn Site to "Read Only" Turn Site to Single "Maintenance Mode" page. Doing any of the above is pretty trivial. You can throw a particular "flag" in an .ini file, or add a row/value to a site_options table in your database and just read that value and do the appropriate thing. But these solutions have their problems. Disadvantages/Problems For instance, if you use a file for your application, and you want to switch off a certain feature temporarily, then you need to update this file on all servers. So then you might want to look at running something like ZooKeeper, but you are probably overcomplicating things. So then, you might decide that you want to store these "feature" flags in a database. But then you are obviously adding unncessary queries to each page request. So you think to yourself, that you will throw memcached in to the mix and just cache the query. Then you just retrieve all of your "Features" from memcached and add a 2ms~ latency to your application on every page. So to get around this, you decide to use a two tier-cache system, whereby you use an inmemory cache on each machine, (like Apc/Redis etc). This would work, but then it gets complicated, because you would have to set the key/hash life to perhaps 60 seconds, so that when you purge/invalidate the memcached object storing your "Features" result, your on machine cache is prompt enough to get the the new states. What suggestions might you have? Keeping in mind that optimization/efficiency is the priority here.
