• Middle tier language for interfacing C/C++ with db and web app

  - by ggkmath

  I have a web application requiring a middle-tier language to communicate between an oracle database and math routines on a Linux server and a flex-based application on a client. I'm not a software expert, and need recommendations for which language to use for the middle-tier. The math routines are currently in Matlab but will be ported to C (or C++) as shared libraries. Thus, by default there's some C or C++ communication necessary. These routines rely on FFTW (www.fftw.org), which is called directly from C or C++ (thus, I don't see re-writing these routines in another language). The middle tier must manage traffic between the client, the math routines, and the Oracle database. The client will trigger the math routines aynchronously, and the results saved in the db and transferred back to the client, etc. The middle-tier will also need to authenticate user accounts/passwords, and send out various administrative emails. Originally I thought PhP the obvious choice, but interfacing asychronously multiple clients with the C or C++ routines doesn't seem straightforward. Then I thought, why not just keep the whole middle tier in C or C++, but I'm not sure if this is done in the industry (C or C++ doesn't seem as web-friendly as other languages). There's always Jave + JNI, but maybe that introduces other complications (not sure). Any feedback appreciated.

• "Walking" along a rotating surface in LimeJS

  - by Dave Lancea

  I'm trying to have a character walk along a plank (a long, thin rectangle) that works like a seesaw, being rotated around a central point by box2d physics (falling objects). I want the left and right arrow keys to move the player up and down the plank, regardless of it's slope, and I don't want to use real physics for the player movement. My idea for achieving this was to compute the coordinate based on the rotation of the plank and the current location "up" or "down" the board. My math is derived from here: http://math.stackexchange.com/questions/143932/calculate-point-given-x-y-angle-and-distance Here's the code I have so far: movement = 0; if(keys[37]){ // Left movement = -3; } if(keys[39]){ // Right movement = 3; } // this.plank is a LimeJS sprite. // getRotation() Should return an angle in degrees var rotation = this.plank.getRotation(); // this.current_plank_location is initialized as 0 this.current_plank_location += movement; var x_difference = this.current_plank_location * Math.cos(rotation); var y_difference = this.current_plank_location * Math.sin(rotation); this.setPosition(seesaw.PLANK_CENTER_X + x_difference, seesaw.PLANK_CENTER_Y + y_difference); This code causes the player to swing around in a circle when they are out of the center of the plank given a slight change in rotation of the plank. Any ideas on how I can get the player position to follow the board position?

• LWJGL Java 2D collision when lagging

  - by user1990950

  I'm using a tile based collision, but when the game is lagging (the lag isn't the problem) the collision fails and the player falls through tiles. This is the movement/collision detection code of my Player class: gravity.y = gspeed; speed.y+=gravity.y; position.set(position.x + direction.x * speed.x * deltaSeconds, position.y + direction.y * speed.y * deltaSeconds); for (int i = (int) Math.round(position.x / 32) - 2 * t; i < (int) Math.round(position.x / 32) + 3 * t; i++) { for (int j = (int) Math.round(position.y / 32); j < (int) Math.round((position.y + height + 64) / 32); j++) { checkCollision(i, j, deltaSeconds); } } public void checkCollision(int i, int j, float deltaSeconds) { bbox.setBounds((int) position.x, (int) position.y, (int) width, (int) height); Tile t = null; t = Map.getTile(i, j); if (t != null) { if (t.isSolid()) { if (t.getTop().intersects(bbox)) { if (position.y + height < t.y * 32 + 32) { if (speed.y >= 0) { position.y = t.y * 32 - height; speed.y = 0; gravity.y = 0; jumpState = 0; } } } if (t.getBottom().intersects(bbox)) { if (position.y < t.y * 32 + 32) { position.y = t.y * 32 + 32; speed.y = 0; } } else { if (t.getLeft().intersects(bbox)) { if (position.x + width > t.x * 32) { position.x = t.x * 32 - width; speed.x = 0; } } if (t.getRight().intersects(bbox)) { if (position.x < t.x * 32 + 32) { position.x = t.x * 32 + 32; speed.x = 0; } } } } } } Is it possible to fix my code, if yes how? Or is it possible to tell if the game is lagging?

• Smooth drag scrolling of an Isometric map - Html5

  - by user881920

  I have implemented a basic Isometric tile engine that can be explored by dragging the map with the mouse. Please see the fiddle below and drag away: http://jsfiddle.net/kHydg/14/ The code broken down is (CoffeeScript): The draw function draw = -> requestAnimFrame draw canvas.width = canvas.width for row in [0..width] for col in [0..height] xpos = (row - col) * tileHeight + width xpos += (canvas.width / 2) - (tileWidth / 2) + scrollPosition.x ypos = (row + col) * (tileHeight / 2) + height + scrollPosition.y context.drawImage(defaultTile, Math.round(xpos), Math.round(ypos), tileWidth, tileHeight) Mouse drag-scrolling control scrollPosition = x: 0 y: 0 dragHelper = active: false x: 0 y: 0 window.addEventListener 'mousedown', (e) => handleMouseDown(e) , false window.addEventListener 'mousemove', (e) => handleDrag(e) , false window.addEventListener 'mouseup', (e) => handleMouseUp(e) , false handleDrag = (e) => e.preventDefault() if dragHelper.active x = e.clientX y = e.clientY scrollPosition.x -= Math.round((dragHelper.x - x) / 28) scrollPosition.y -= Math.round((dragHelper.y - y) / 28) handleMouseUp = (e) => e.preventDefault() dragHelper.active = false handleMouseDown = (e) => e.preventDefault() x = e.clientX y = e.clientY dragHelper.active = true dragHelper.x = x dragHelper.y = y The Problem As you can see from the fiddle the dragging action is ok but not perfect. How would I change the code to make the dragging action more smooth? What I would like is the point of the map you click on to stay under the mouse point whilst you drag; the same as they have done here: http://craftyjs.com/demos/isometric/

• Lerping to a center point while in motion

  - by Fibericon

  I have an enemy that initially flies in a circular motion, while facing away from the center point. This is how I achieve that: position.Y = (float)(Math.Cos(timeAlive * MathHelper.PiOver4) * radius + origin.Y); position.X = (float)(Math.Sin(timeAlive * MathHelper.PiOver4) * radius + origin.X); if (timeAlive < 5) { angle = (float)Math.Atan((0 - position.X) / (0 - position.Y)); if (0 < position.Y) RotationMatrix = Matrix.CreateRotationX(MathHelper.PiOver2) * Matrix.CreateRotationZ(-1 * angle); else RotationMatrix = Matrix.CreateRotationX(MathHelper.PiOver2) * Matrix.CreateRotationZ(MathHelper.Pi - angle); } That part works just fine. After five seconds of this, I want the enemy to turn inward, facing the center point. However, I've been trying to lerp to that point, since I don't want it to simply jump to the new rotation. Here's my code for trying to do that: else { float newAngle = -1 * (float)Math.Atan((0 - position.X) / (0 - position.Y)); angle = MathHelper.Lerp(angle, newAngle, (float)gameTime.ElapsedGameTime.Milliseconds / 1000); if (0 < position.Y) RotationMatrix = Matrix.CreateRotationX(MathHelper.PiOver2) * Matrix.CreateRotationZ(MathHelper.Pi - angle); else RotationMatrix = Matrix.CreateRotationX(MathHelper.PiOver2) * Matrix.CreateRotationZ(-1 * angle); } That doesn't work so fine. It seems like it's going to at first, but then it just sort of skips around. How can I achieve what I want here?

• what's wrong with my lookAt and move forward code?

  - by alaslipknot

  so am still in the process of getting familiar with libGdx and one of the fun things i love to do is to make basics method for reusability on future projects, and for now am stacked on getting a Sprite rotate toward target (vector2) and then move forward based on that rotation the code am using is this : // set angle public void lookAt(Vector2 target) { float angle = (float) Math.atan2(target.y - this.position.y, target.x - this.position.x); angle = (float) (angle * (180 / Math.PI)); setAngle(angle); } // move forward public void moveForward() { this.position.x += Math.cos(getAngle())*this.speed; this.position.y += Math.sin(getAngle())*this.speed; } and this is my render method : @Override public void render(float delta) { // TODO Auto-generated method stub Gdx.gl.glClearColor(0, 0, 0.0f, 1); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); // groupUpdate(); Vector3 mousePos = new Vector3(Gdx.input.getX(), Gdx.input.getY(), 0); camera.unproject(mousePos); ball.lookAt(new Vector2(mousePos.x, mousePos.y)); // if (Gdx.input.isTouched()) { ball.moveForward(); } batch.begin(); batch.draw(ball.getSprite(), ball.getPos().x, ball.getPos().y, ball .getSprite().getOriginX(), ball.getSprite().getOriginY(), ball .getSprite().getWidth(), ball.getSprite().getHeight(), .5f, .5f, ball.getAngle()); batch.end(); } the goal is to make the ball always look at the mouse cursor, and then move forward when i click, am also using this camera : // create the camera and the SpriteBatch camera = new OrthographicCamera(); camera.setToOrtho(false, 800, 480); aaaand the result was so creepy lol Thank you

• Visual Studio 2008 maintenance mode - I can't remember my installation source drive letter!!!

  - by Dave

  I've searched high and low for this and can't find the answer anywhere. I installed VS2008, but my drive letters are all mapped differently now, and of course I need to add a component to my current installation (VC++). But since I don't know which drive letter it was installed from, and since I don't want to try to figure it out the brute force way, I was hoping that someone here knew how to figure that out. I poked through HKCU and HKLM in the registry, hoping to find the info there, but couldn't. Does anyone know how to get this to work? Right now, I get the error "A selected drive is no longer valid. Please review your installation path settings before continuing with setup".

• Sensor Manager getOrientation, doesnt display text and only works in debug mode?

  - by Aidan

  Hi Guys, My code appears to crash. I'm trying to setup a SensorManager for getting the Orientation of the device. I also have a listener that should update when conditions change. But when I run this code it crashes... public void sensor(){ // Locate the SensorManager using Activity.getSystemService sm = (SensorManager) getSystemService(SENSOR_SERVICE); sm.getOrientation(mR, mOrientation); // Register your SensorListener sm.registerListener(sl, sm.getDefaultSensor(Sensor.TYPE_ORIENTATION),SensorManager.SENSOR_DELAY_NORMAL); } private final SensorEventListener sl = new SensorEventListener() { @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { } @Override public void onSensorChanged(SensorEvent event) { if (event.sensor.getType()==Sensor.TYPE_ORIENTATION) { Global.Orientation = "Orientation is equal to: "+ SensorManager.getOrientation(mR, mOrientation); } } sm is defined as SensorManager sm; as a class wide variable also. I've got some other classes outputting the Orientation to a screen which I know works. The problem is somewhere in these methods. Am I doing it wrong or Is there a better way of doing this?

• Any way to disable horizontal scroll for FlowLayoutPanel in AutoScroll mode?

  - by P a u l

  I need a System.Windows.Forms.FlowLayoutPanel that only auto scrolls vertically. WrapContents is false, and I want it to work like a vertical stack panel. I can't find a way to disable the horizontal scroll. I've googled it, can't find a usable solution so far. The alternative is to abandon the FlowLayoutPanel, and try another control. What acts somewhat like a WPF stack panel but that expands and shrinks vertically with the contained controls?

• How to encrypt an NSString in Objective C with DES in ECB-Mode?

  - by blauesocke

  Hi, I am trying to encrypt an NSString in Objective C on the iPhone. At least I wan't to get a string like "TmsbDaNG64lI8wC6NLhXOGvfu2IjLGuEwc0CzoSHnrs=" when I encode "us=foo;pw=bar;pwAlg=false;" by using this key: "testtest". My problem for now is, that CCCrypt always returns "4300 - Parameter error" and I have no more idea why. This is my code (the result of 5 hours google and try'n'error): NSString *token = @"us=foo;pw=bar;pwAlg=false;"; NSString *key = @"testtest"; const void *vplainText; size_t plainTextBufferSize; plainTextBufferSize = [token length]; vplainText = (const void *) [token UTF8String]; CCCryptorStatus ccStatus; uint8_t *bufferPtr = NULL; size_t bufferPtrSize = 0; size_t *movedBytes; bufferPtrSize = (plainTextBufferSize + kCCBlockSize3DES) & ~(kCCBlockSize3DES - 1); bufferPtr = malloc( bufferPtrSize * sizeof(uint8_t)); memset((void *)bufferPtr, 0x0, bufferPtrSize); // memset((void *) iv, 0x0, (size_t) sizeof(iv)); NSString *initVec = @"init Vec"; const void *vkey = (const void *) [key UTF8String]; const void *vinitVec = (const void *) [initVec UTF8String]; ccStatus = CCCrypt(kCCEncrypt, kCCAlgorithmDES, kCCOptionECBMode, vkey, //"123456789012345678901234", //key kCCKeySizeDES, NULL,// vinitVec, //"init Vec", //iv, vplainText, //"Your Name", //plainText, plainTextBufferSize, (void *)bufferPtr, bufferPtrSize, movedBytes); NSString *result; NSData *myData = [NSData dataWithBytes:(const void *)bufferPtr length:(NSUInteger)movedBytes]; result = [myData base64Encoding];

• How i can add border to ListViewItem, ListView in GridView mode.

  - by Andrew

  Hello! I want to have a border around ListViewItem (row in my case). ListView source and columns generated during Runtime. In XAML i have this structure: <ListView Name="listViewRaw"> <ListView.View> <GridView> </GridView> </ListView.View> </ListView> During Runtime i bind listview to DataTable, adding necessary columns and bindings: var view = (listView.View as GridView); view.Columns.Clear(); for (int i = 0; i < table.Columns.Count; i++) { GridViewColumn col = new GridViewColumn(); col.Header = table.Columns[i].ColumnName; col.DisplayMemberBinding = new Binding(string.Format("[{0}]", i.ToString())); view.Columns.Add(col); } listView.CoerceValue(ListView.ItemsSourceProperty); listView.DataContext = table; listView.SetBinding(ListView.ItemsSourceProperty, new Binding()); So i want to add border around each row, and set border behavior (color etc) with DataTriggers (for example if value in 1st column = "Visible", set border color to black). Can i put border through DataTemplate in ItemTemplate? I know solution, where you manipulate with CellTemplates, but i don't really like it. I want something like this if this even possible. <DataTemplate> <Border Name="Border" BorderBrush="Transparent" BorderThickness="2"> <ListViewItemRow><!-- Put my row here, but i ll know about table structure only during runtime --></ListViewItemRow> </Border> </DataTemplate>

• Error displaying a WinForm in Design mode with a custom control on it.

  - by George

  I have a UserControl that is part of a Class library. I reference this project from my solution. This adds a control from the referenced project to my toolbox. I add tghe control to a form. Everything looks good, I compile all and run. Perfect... But when I close the .frm with the control on it and re-open it, I get this error. The code continues to run. It may have something to do with namespaces. The original namespace was simply "Design" and this was ambiguous and conflicting so i decided to rename it. I think that's when my problems began.

• Can a View Controller manage more than 1 nib based view?

  - by Hugo Brynjar

  I have a VC controlling a screen of content that has 2 modes; a normal mode and an edit mode. Can I create a single VC with 2 views, each from separate nibs? In many situations on the iphone, you have a VC which controls an associated view. Then on a button press or other event, a new VC is loaded and its view becomes the top level view etc. But in this situation, I have 2 modes that I want to use the same VC for, because they are closely related. So I want a VC which can swap in/out 2 views. As per here: http://stackoverflow.com/questions/863321/iphone-how-to-load-a-view-using-a-nib-file-created-with-interface-builder/2683153#2683153 I have found that I can load a VC with an associated view from a nib and then later on load a different view from another nib and make that new view the active view. NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"EditMode" owner:self options:nil]; UIView *theEditView = [nibObjects objectAtIndex:0]; self.editView = theEditView; [self.view addSubview:theEditView]; The secondary nib has outlets wired up to the VC like the primary nib. When the new nib is loaded, the outlets are all connected up fine and everything works nicely. Unfortunately when this edit view is then removed, there doesn't seem to be any elegant way of getting the outlets hooked up again to the (normal mode) view from the original nib. Nib loading and outlet setting seems a once only thing. So, if you want to have a VC that swaps in/out 2 views without creating a new VC, what are the options? 1) You can do everything in code, but I want to use nibs because it makes creating the UI simpler. 2) You have 1 nib for your VC and just hide/show elements using the hidden property of UIView and its subclasses. 3) You load a new nib as described above. This is fine for the new nib, but how do you sort the outlets when you go back to the original nib. 4) Give up and accept having a 1:1 between VCs and nibs. There is a nib for normal mode, a nib for edit mode and each mode has a VC that subclasses a common superclass. In the end, I went with 4) and it works, but requires a fair amount of extra work, because I have a model class that I instantiate in normal mode and then have to pass to the edit mode VC because both modes need access to the model. I'm also using NSTimer and have to start and stop the timer in each mode. It is because of all this shared functionality that I wanted a single VC with 2 nibs in the first place.

• What permissions do I need to grant to run RavenDB in Server mode?

  - by dalesmithtx

  I'm reading through Rob Ashton's excellent blog post on RavenDB: http://codeofrob.com/archive/2010/05/09/ravendb-an-introduction.aspx and I'm working through the code as I read. But when I try to add an index, I get a 401 error. Here's the code: class Program { static void Main(string[] args) { using (var documentStore = new DocumentStore() { Url = "http://localhost:8080" }) { documentStore.Initialise(); documentStore.DatabaseCommands.PutIndex( "BasicEntityBySomeData", new IndexDefinition<BasicEntity, BasicEntity>() { Map = docs => from doc in docs where doc.SomeData != null select new { SomeData = doc.SomeData }, }); string entityId; using (var documentSession = documentStore.OpenSession()) { var entity = new BasicEntity() { SomeData = "Hello, World!", SomeOtherData = "This is just another property", }; documentSession.Store(entity); documentSession.SaveChanges(); entityId = entity.Id; var loadedEntity = documentSession.Load<BasicEntity>(entityId); Console.WriteLine(loadedEntity.SomeData); var docs = documentSession.Query<BasicEntity>("BasicEntityBySomeData") .Where("SomeData:Hello~") .WaitForNonStaleResults() .ToArray(); docs.ToList().ForEach(doc => Console.WriteLine(doc.SomeData)); Console.Read(); } } } It throws the 401 error when on the line that makes the PutIndex() call. Any ideas what permissions I need to apply? And where I need to apply them?

• Enable scratch buffer to execute R code in emacs-ess

  - by sheed03

  Hello, I have switched to using emacs-ess for my R code development and it is working great. I would like to be able to write some small R code I am using for debugging my R script into the scratch buffer, and be able to execute the scratch buffer code in the R process buffer. I've found how I could change the scratch buffer's mode to text by putting the following in the .emacs file: (setq initial-major-mode 'text-mode) Is there a similar statement I can put in my .emacs file that would make the scratch buffer have the ess-mode? I tried the following which results in an error about wrong type argument: (setq initial-major-mode 'ess-mode)

• Can I use the auto-generated Linq-to-SQL entity classes in 'disconnected' mode?

  - by Gary McGill

  Suppose I have an automatically-generated Employee class based on the Employees table in my database. Now suppose that I want to pass employee data to a ShowAges method that will print out name & age for a list of employees. I'll retrieve the data for a given set of employees via a linq query, which will return me a set of Employee instances. I can then pass the Employee instances to the ShowAges method, which can access the Name & Age fields to get the data it needs. However, because my Employees table has relationships with various other tables in my database, my Employee class also has a Department field, a Manager field, etc. that provide access to related records in those other tables. If the ShowAges method were to invoke any of those methods, this would cause lots more data to be fetched from the database, on-demand. I want to be sure that the ShowAges method only uses the data I have already fetched for it, but I really don't want to have to go to the trouble of defining a new class which replicates the Employee class but has fewer methods. (In my real-world scenario, the class would have to be considerably more complex than the Employee class described here; it would have several 'joined' classes that do need to be populated, and others that don't). Is there a way to 'switch off' or 'disconnect' the Employees instances so that an attempt to access any property or related object that's not already populated will raise an exception? If not, then I assume that since this must be a common requirement, there might be an already-established pattern for doing this sort of thing?

• In VisualStudio 2008, emacs mode - how can you enable "overwrite"?

  - by Abby Fichtner

  Using VisualStudio 2008, have emacs keyboard mapping scheme enabled. If I select text and try to paste over it, it INSERTS the new text, rather than replacing it. Also, if I select text and hit DELETE it deletes the first character AFTER the selected text (just as if I didn't have any text selected). Does anyone know how to fix this so that I get the standard windows behavior. That is: If I select text and try to paste over it, it replaces the selected text with what I pasted in. If I select text and hit the DELETE key, it actually deletes the text I have selected Thanks! Abby
