  • Is Python worth learning? Is it a useful tool?

    - by Kenneth
    I recently had a discussion with a professor of mine on the topic of web development. I had recently decided I would learn python to increase my arsenal of web tools which I mentioned to him at that time. He almost immediately asked why I would waste my time on that. I'm not certain but I think he recently started in on researching and studying web development so he could pick up the web development classes that haven't been taught for a while after the previous professor who taught those classes left. I've heard a lot about python and thought maybe he was mistaken about its usefulness. Is python a useful tool to have? What applications can it be used for? Is it better than other similar alternatives? Does it have useful applications outside of web development as well?

  • Java game object pool management

    - by Kenneth Bray
    Currently I am using arrays to handle all of my game objects in the game I am making, and I know how terrible this is for performance. My question is what is the best way to handle game objects and not hurt performance? Here is how I am creating an array and then looping through it to update the objects in the array: public static ArrayList<VboCube> game_objects = new ArrayList<VboCube>(); /* add objects to the game */ while (!Display.isCloseRequested() && !Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) { for (int i = 0; i < game_objects.size(); i++){ // draw the object game_objects.get(i).Draw(); game_objects.get(i).Update(); //world.updatePhysics(); } } I am not looking for someone to write me code for asset or object management, just point me into a better direction to get better performance. I appreciate the help you guys have provided me in the past, and I dont think I would be as far along with my project without the support on stack exchange!

  • Rotating a cube using jBullet collisions

    - by Kenneth Bray
    How would one go about rotating/flipping a cube with the physics of jBullet? Here is my Draw method for my cube object: public void Draw() { // center point posX, posY, posZ float radius = .25f;//size / 2; glPushMatrix(); glBegin(GL_QUADS); //top { glColor3f(5.0f,1.0f,5.0f); // white glVertex3f(posX + radius, posY + radius, posZ - radius); glVertex3f(posX - radius, posY + radius, posZ - radius); glVertex3f(posX - radius, posY + radius, posZ + radius); glVertex3f(posX + radius, posY + radius, posZ + radius); } //bottom { glColor3f(1.0f,1.0f,0.0f); // ?? color glVertex3f(posX + radius, posY - radius, posZ + radius); glVertex3f(posX - radius, posY - radius, posZ + radius); glVertex3f(posX - radius, posY - radius, posZ - radius); glVertex3f(posX + radius, posY - radius, posZ - radius); } //right side { glColor3f(1.0f,0.0f,1.0f); // ?? color glVertex3f(posX + radius, posY + radius, posZ + radius); glVertex3f(posX + radius, posY - radius, posZ + radius); glVertex3f(posX + radius, posY - radius, posZ - radius); glVertex3f(posX + radius, posY + radius, posZ - radius); } //left side { glColor3f(0.0f,1.0f,1.0f); // ?? color glVertex3f(posX - radius, posY + radius, posZ - radius); glVertex3f(posX - radius, posY - radius, posZ - radius); glVertex3f(posX - radius, posY - radius, posZ + radius); glVertex3f(posX - radius, posY + radius, posZ + radius); } //front side { glColor3f(0.0f,0.0f,1.0f); // blue glVertex3f(posX + radius, posY + radius, posZ + radius); glVertex3f(posX - radius, posY + radius, posZ + radius); glVertex3f(posX - radius, posY - radius, posZ + radius); glVertex3f(posX + radius, posY - radius, posZ + radius); } //back side { glColor3f(0.0f,1.0f,0.0f); // green glVertex3f(posX + radius, posY - radius, posZ - radius); glVertex3f(posX - radius, posY - radius, posZ - radius); glVertex3f(posX - radius, posY + radius, posZ - radius); glVertex3f(posX + radius, posY + radius, posZ - radius); } glEnd(); glPopMatrix(); Update(); } This is my update method for the cube position: public void Update() { Transform trans = new Transform(); cubeRigidBody.getMotionState().getWorldTransform(trans); posX = trans.origin.x; posY = trans.origin.y; posZ = trans.origin.z; Quat4f outRot = new Quat4f(); trans.getRotation(outRot); rotX = outRot.x; rotY = outRot.y; rotZ = outRot.z; rotW = outRot.w; } I am assuming I need to use glrotatef, but it does not seem to work at all when I try that.. this is how I have tried to rotate the cubes: GL11.glRotatef(rotW, rotX, 0.0f, 0.0f); GL11.glRotatef(rotW, 0.0f, rotY, 0.0f); GL11.glRotatef(rotW, 0.0f, 0.0f, rotZ);

  • jBullet Collision/Physics not working as expected

    - by Kenneth Bray
    Below is the code for one of my objects in the game I am creating (yes although this is a cube, I am not making anything remotely like MineCraft), and my issue is I while the cube will display and is does follow the physics if the cube falls, it does not interact with any other objects in the game. If I was to have multiple cubes in screen at once they all just sit there, or shoot off in all directions never stopping. Anyway, I am new to jBullet, and any help would be appreciated. // Constructor public Cube(float pX, float pY, float pZ, float pSize) { posX = pX; posY = pY; posZ = pZ; size = pSize; rotX = 0; rotY = 0; rotZ = 0; // physics stuff fallMotionState = new DefaultMotionState(new Transform(new Matrix4f(new Quat4f(0, 0, 0, 1), new Vector3f(posX, posY, posZ), 1))); fallRigidBodyCI = new RigidBodyConstructionInfo(mass, fallMotionState, fallShape, fallInertia); fallRigidBody = new RigidBody(fallRigidBodyCI); }

  • Moving the jBullet collision body to with the player object

    - by Kenneth Bray
    I am trying to update the location of the rigid body for a player class, as my player moves around I would like the collision body to also move with the player object (currently represented as a cube). Below is my current update method for when I want to update the xyz coords, but I am pretty sure I am not able to update the origin coords? : public void Update(float pX, float pY, float pZ) { posX = pX; posY = pY; posZ = pZ; //update the playerCube transform for the rigid body cubeTransform.origin.x = posX; cubeTransform.origin.y = posY; cubeTransform.origin.z = posZ; cubeRigidBody.getMotionState().setWorldTransform(cubeTransform); processTransformMatrix(cubeTransform); } I do not have rotation updated, as I do not actually want/need the player body to rotate at all currently. However, in the final game this will me put in place.

  • HowTo Enable jBullet DebugMode

    - by Kenneth Bray
    I would like to render the physics world of jBullet to debug some issues in my game, and I am not finding too much on enabling the debugDraw method of jBullet. Do I need to write my own debugDraw method, or is there an easier way to draw the physics models to the screen? If there is already a built in method I would prefer to use that, otherwise I guess I will start making my own functions to handle this.

  • The ghost of icons past

    - by Kenneth Cochran
    I am fortnightly( or an approximation thereof) visited by the ghosts of icons, long departed. These apparitions only reveal themselves momentarily after I've logged in then vanish. Returning from whence they came. I've investigated their history and found no clues as to why they continue to haunt me. I sought out an exorcist but those I found were only qualified to expel spirits of humans and demons. Not one had any experience with digital poltergeists. Perhaps praying to Saint William of Redmond will improve the Vista before me. Dost thou agree?

  • Share internet with my phone?

    - by Kenneth Cochran
    Most people want to use their cellphone as a modem for their computer, commonly referred to as 'tethering'. I'm actually interested in doing the opposite: Sharing my landline internet connection(which is much faster than any 3G service) with by cellphone. My phone is a Verizon BlackBerry Curve 8330 and it has USB and bluetooth connections. I know both USB and Bluetooth are capable of supporting tcp/ip traffic what's not so clear is: Is IP over USB or Bluetooth standardized? Is it supported on my phone? Has my cellphone company crippled my phone to prevent me from using it?

  • What is the easiest way to do a direct file transfer of an extremely large file over the Internet?

    - by Kenneth Cochran
    I would like to transfer a 20+ GB file to a friend. I would like it to: Be fast Ensure data integrity Not require opening ports in either end's firewall Be free Not broadcast the file's existence to everyone on the Internet I've looked a several technologies and nothing seems to fit: Gnutella, BitTorrent, et al. satisfies 1, 2 and 4 JetBytes... 1, 3, 4 and 5 Yahoo Messenger, AIM, etc. 3, 4 and 5 FTP, SFTP... 1?, 4 and 5 rsync... 1, 2, 4 and 5 For a file this size speed and data integrity are the most important. No one wants a 20 GB file to fail a MD5 check after spending two days downloading it. Is there anything that meets all these requirements?

  • Open port in gufw is closed, no incoming connection on deluge

This is connected to the firewall. Because when I turn off the firewall, the port is open. So this is not a problem with my modem. Do I need the firewall? The broadband modem has a hardware firewall. Update: Forgot to add. When my firewall is inactive, it closes ports after a time. So when I use linuxdc, I have to flush iptabels and activating it again. Is this supposed to do this when the firewall is deactivated? Update again: All my ports are closed now, flushing the iptable does not work anymore. I have uninstalled gufw, but still all my ports are closed. And to say it again, this has nothing to do with my broadband modem since it worked when I used windows 7. I need help to open the ports.

  • Synchronizing a collection of wrapped objects with a collection of unwrapped objects

    - by Kenneth Cochran
    I have two classes: Employee and EmployeeGridViewAdapter. Employee is composed of several complex types. EmployeeGridViewAdapter wraps a single Employee and exposes its members as a flattened set of system types so a DataGridView can handle displaying, editing, etc. I'm using VS's builtin support for turning a POCO into a data source, which I then attach to a BindingSource object. When I attach the DataGridView to the BindingSource it creates the expected columns and at runtime I can perform the expected CRUD operations. All is good so far. The problem is the collection of adapters and the collection of employees aren't being synchronized. So all the employees I create an runtime never get persisted. Here's a snippet of the code that generates the collection of EmployeeGridViewAdapter's: var employeeCollection = new List<EmployeeGridViewAdapter>(); foreach (var employee in this.employees) { employeeCollection.Add(new EmployeeGridViewAdapter(employee)); } this.view.Employees = employeeCollection; Pretty straight forward but I can't figure out how to synchronize changes back to the original collection. I imagine edits are already handled because both collections reference the same objects but creating new employees and deleting employees aren't happening so I can't be sure.

  • DataTable to Object collection

    - by Kenneth Cochran
    I'm working on a data import feature and I've been able to load an excel sheet into a DataTable using Ado.NET with the MSJet db engine. I created a simple one-to-one mapping dialog, in which the user drags column headings from their spreadsheet to a list of object properties. What's stumping me is how to turn each DataRow into a business object. Is there an easy way to do this? If there is a better way than using a DataTable as a middleman I'm open to suggestion? I use NHibernate extensively through out the rest of my program but I couldn't find any attempts to map to an excel spreadsheet. I went with a DataTable because the technique was well documented.

  • Techniques for sharing a value among classes in a program

    - by Kenneth Cochran
    I'm using Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\MyProgram" As the path to store several files used by my program. I'd like to avoid pasting the same snippet of code all over the my applcation. I need to ensure that: The path cannot be accidentally changed once its been set The classes that need it have access to it. I've considered: Making it a singleton Using constructor dependency injection Using property dependency injection Using AOP to create the path where its needed. Each has pros and cons. The singleton is everyone's favorite whipping boy. I'm not opposed to using one but there are valid reasons to avoid it if possible. I'm already heavily using constructor injection through Castle Windsor. But this is a path string and Windsor doesn't handle system type dependencies very gracefully. I could always wrap it in a class but that seems like overkill for something as simple as a passing around a string value. In any case this route would add yet another constructor argument to each class where it is used. The problem I see with property injection in this case is that there is a large amount of indirection from the where the value is set to where it is needed. I would need a very long line of middlemen to reach all the places where its used. AOP looks promising and I'm planning on using AOP for logging anyway so this at least sounds like a simple solution. Is there any other options I haven't considered? Am I off base with my evaluation of the options I have considered?

  • C# Fun with Generics - Mutual Dependencies

    - by Kenneth Cochran
    As an experiment I'm trying to write a generic MVP framework. I started with: public interface IPresenter<TView> where TView: IView<IPresenter<... { TView View { get; set;} } public interface IView<TPresenter> where TPresenter:IPresenter<IView<... { TPresenter Presenter { get; set; } } Obviously this can't work because the types of TView and TPresenter can't be resolved. You'd be writing Type<Type<... forever. So my next attempt looked like this: public interface IView<T> where T:IPresenter { ... } public interface IView:IView<IPresenter> { } public interface IPresenter<TView> where TView: IView { ... } public interface IPresenter: IPresenter<IView> { ... } This actually compiles and you can even inherit from these interfaces like so: public class MyView : IView, IView<MyPresenter> { ... } public class MyPresenter : IPresenter, IPresenter<MyView> { ... } The problem is in the class definition you have to define any members declared in the generic type twice. Not ideal but it still compiles. The problem's start creeping up when you actually try to access the members of a Presenter from a View or vice versa. You get an Ambiguous reference when you try to compile. Is there any way to avoid this double implementation of a member when you inherit from both interfaces? Is it even possible to resolve two mutually dependent generic types at compile time?

  • SubSonic 3 issue creating List<>

    - by Brian Cochran
    I have an application that requires we use distinct user connection strings per user. We are trying to upgrade from SubSonic 2.x to 3.0. I'm running into issues with trying to create a List< of objects. When I try to create a List like this: List<table_name> oList = table_name.All().Where(tn => tn.table_id == TableId).ToList(); I get the error "Connection string 'ConnectionStringName' does not exist." So, I try to create the List< like this: List<table_name> oList = table_name.All(sConnectionString, "System.Data.SqlClient").Where(tn => tn.table_id == TableId).ToList(); I get the error "The name 'table_name' does not exist in the current context." I'm using SQL Server, and the sConnectionString is definitely verified to be a good connection string, and the table_name is a table in the database. What am I doing wrong?

  • SharePoint Records Center Submitted E-mail Records not picked up

    - by Kenneth Verburg
    We have set up a new SharePoint 2007 site with a Records Repository. We're using Exchange 2007 Managed Folders to route e-mails to this repository based on the 'label' attached to the e-mail as set in the Exchange 2007 journaling options. E-mails added to a Managed Folder get sent to SharePoint, they end up in the "Submitted E-mail Records" list of the Records Repository. That's according to plan, but the e-mails are not routed to the respective document library as defined by the label. Instead an error appears in the event viewer for every e-mail listed in the Submitted E-mail Records list, on every interval of the records repository schedule (set to every two minutes for testing purposes): Value cannot be null, parameter name: g. Sending a document from the SharePoint site iself to the Records Repository via the Send To... link works fine, but e-mails get stuck in the list... We have set Document Libraries in the Respository with and without content types (with matching names with the Label and the Record Routing rule set). Any ideas what could be wrong? This is in the event log: Every two minutes the following error appears in the Application Log: Source: Office SharePoint Server Category: Records Center Type: Error Event ID: 4975 User: N/A Computer: SPS2007 Description: Value cannot be null. Parameter name: g For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

  • Change the number of consecutive frequent ssh login before temporary blocking the user login

    - by Kenneth
    my server currently would temporarily refuse a user to login for certain amount of time (maybe ~20min) if the user consecutively frequent ssh login for 3 times. Can I change this behaviour (say relaxed the definition of frequent maybe from 'within 5 sec' to 'within 10 sec'; or increase the # of consecutive login from 3 to 5)? Thanks. Added: Ah.. now I think the problem was not with the ssh. I just tried on another newly installed server. consecutive successful login won't block the user. I have no sudo permission on the server I mentioned above. Now I suspect this behaviour may cause by the firewall in the system. Thanks everyone's comments. ADDED 2: Ah... after some searches. I think the server is using /sbin/iptables to do it as I can see the iptables program is there even though I don't have permission to list the rules. Thanks everyone, special thank to jaume and Mark!

  • Problems getting Squirrelmail and passenger working on apache

    - by Kenneth
    I'm trying to have a setup where I want to run a squirrelmail and Passenger on the same apache server, having a url point to squirrelmail and everything else handled by passenger. I've gotten so far that both squirrelmail and passenger will run fine by themselves but when passenger is running it handles all urls. So far I've tried using Alias and Redirect to point a webmail/ url to squirrelmails directory but that does not work. Here is my httpd.conf file: <VirtualHost *:80> ServerName not.my.real.server.name DocumentRoot /var/www/sinatra/public # Does not work: #Redirect webmail/ /usr/share/squirrelmail/ #<Directory /usr/share/squirrelmail> # Require all granted #</Directory> <Directory /var/www/sinatra/public> Order allow,deny Allow from all </Directory> </VirtualHost>

  • Dell PS/2 Keyboard Stops Working Randomly After Power Disturbance

    - by Kenneth Murphy
    I have a Dell PS/2 keyboard connected to a desktop PC running Slackware 12.2 & Windows XP. After a recent, brief power outage/disturbance at my home, the keyboard has begun to quit working at random times. It has stopped at POST, but not by keyboard error -- I have to press the F1 key to continue booting, and at times the keyboard has already stopped working. Other times, the keyboard will work perfectly for a long time (a day or more) before it finally quits. It has stopped at boot, in Windows XP, and in Slackware. The led lights continue to work regardless. I have tried another PS/2 keyboard and it seems to be immune to this problem. The USB mouse always works. Does anyone have any ideas about how this might have happened? If this is related to the power disturbance that killed the power to the running PC, is it feasible that it would have only fried the keyboard itself (which still works sometimes) and not the PS/2 port nor anything else? I have experienced no other problems since the event.
