  • Logging in over and over again. How to fix this?

    - by romeovs
    Ok, I messed up. I installed ubuntu 11.10, installed awesome wm and removed unity, to have something to fall back on, I also installed gnome-session-fallback. I was messing around and did the following, because the awesome wiki told me to: gconftool-2 --type bool --set /apps/nautilus/preferences/show_desktop False # Still disable the buggy Nautilus desktop thing gconftool-2 --type string --set /desktop/gnome/session/required_components/windowmanager awesome # sets awesome as wm Now here's what's wrong: I can start up decently, and then I get into a login window (that of gnome-session-fallback). I enter my username, select the preferred window manager (awesome in my case) and enter my password. It accepts these, but then hold for a second and just opens the login window again, in effect preventing me from actually logging in. I also tried gconftool-2 --unset (from the tty) on these settings, but that didn't work either. What can I do to revert the gconftool-2 settings to something that should work? I tried apt-get purging gnome-session-fallback and lightdm, and then installing them again, but that didn't work.

  • Android 2D terrain scrolling

    - by Nikola Ninkovic
    I want to make infinite 2D terrain based on my algorithm.Then I want to move it along Y axis (to the left) This is how I did it : public class Terrain { Queue<Integer> _bottom; Paint _paint; Bitmap _texture; Point _screen; int _numberOfColumns = 100; int _columnWidth = 20; public Terrain(int screenWidth, int screenHeight, Bitmap texture) { _bottom = new LinkedList<Integer>(); _screen = new Point(screenWidth, screenHeight); _numberOfColumns = screenWidth / 6; _columnWidth = screenWidth / _numberOfColumns; for(int i=0;i<=_numberOfColumns;i++) { // Generate terrain point and put it into _bottom queue } _paint = new Paint(); _paint.setStyle(Paint.Style.FILL); _paint.setShader(new BitmapShader(texture, Shader.TileMode.REPEAT, Shader.TileMode.REPEAT)); } public void update() { _bottom.remove(); // Algorithm calculates next point _bottom.add(nextPoint); } public void draw(Canvas canvas) { Iterator<Integer> i = _bottom.iterator(); int counter = 0; Path path = new Path(); path.moveTo(0, _screen.y); while (i.hasNext()) { path.lineTo(counter, _screen.y-i.next()); counter += _columnWidth; } path.lineTo(_screen.x, _screen.y); path.lineTo(0, _screen.y); canvas.drawPath(path2, _paint); } } The problem is that the game is too 'fast', so I tried with pausing thread with Thread.sleep(50); in run() method of my game thread but then it looks too torn. Well, is there any way to slow down drawing of my terrain ?

  • Can I use Unity with XMonad?

    - by geniass
    I've been using Fedora for a while, but I recently decided to upgrade my ubuntu installation from 12.04 to 12.10. While I was using Fedora, I found xmonad tiling window manager which I sort of got working with xfce. I really like xmonad and I now automatically use the keyboard shortcuts without even thinking. So I would like to use xmonad with unity. Now, I have seen several blog posts etc. that explain how to setup the whole thing in 12.04, with Unity2D. But now, Unity2D has been removed, and the old methods no longer apply. I have read that Unity is actually just a Compiz plugin, and that the wm can't be replaced. Does no version of Unity have a replaceable WM? I've also tried MATE (GNOME2 fork) with xmonad on 12.10 and that is totally broken for me, but that's for another question.

    - by Shirisha
    I am trying to create app which is match text with appropriate images by pointing with line. I want to create app exactly same which is shown in the below image: can any one please give me an idea? This is my main class: public class MatchActivity extends Activity { ArrayAdapter<String> listadapter; float x1; float y1; float x2; float y2; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); String[] s1 = { "smiley1", "smiley2", "smiley3" }; ListView lv = (ListView) findViewById(R.id.text_list); ArrayList<String> list = new ArrayList<String>(); list.addAll(Arrays.asList(s1)); listadapter = new ArrayAdapter<String>(this, R.layout.rowtext, s1); lv.setAdapter(listadapter); GridView gv = (GridView) findViewById(R.id.image_list); gv.setAdapter(new ImageAdapter(this)); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> arg0, View v, int arg2, long arg3){ x1=v.getX(); y1=v.getY(); Log.d("list","text positions x1:"+x1+" y1:"+y1); } }); gv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> arg0, View v, int arg2, long arg3){ DrawView draw=new DrawView(MatchActivity.this); x2=v.getX(); y2=v.getY(); draw.position1.add(x1); draw.position1.add(y1); draw.position2.add( x2); draw.position2.add(y2); Log.d("list","image positions x2:"+x2+" y2:"+y2); LinearLayout ll=LinearLayout)findViewById(R.id.draw_line); ll.addView(draw); } }); } } This is my drawing class to draw a line: public class DrawView extends View { Paint paint = new Paint(); private List<Float> position1=new ArrayList<Float>(); private List<Float> position2=new ArrayList<Float>();; public DrawView(Context context) { super(context); invalidate(); Log.d("drawview","In DrawView class position1:"+position1+" position2:"+position2) ; } @Override public void onDraw(Canvas canvas) { super.onDraw(canvas); Log.d("on draw","IN onDraw() position1:"+position1+" position2:"+position2); assert position1.size() == position2.size(); for (int i = 0; i < position1.size(); i += 2) { float x1 = position1.get(i); float y1 = position1.get(i + 1); float x2 = position2.get(i); float y2 = position2.get(i + 1); paint.setColor(Color.BLACK); paint.setStrokeWidth(3); canvas.drawLine(x1,y1, x2,y2, paint); } } } Thanks in advance .

  • The busy developers guide to the Kinect SDK Beta

    - by mbcrump
    The Kinect is awesome. From day one, I’ve said this thing has got potential. After playing with several open-source Kinect projects, I am please to announce that Microsoft has released the official SDK beta on 6/16/2011. I’ve created this quick start guide to get you up to speed in no time flat. Let’s begin: What is it? The Kinect for Windows SDK beta is a starter kit for applications developers that includes APIs, sample code, and drivers. This SDK enables the academic research and enthusiast communities to create rich experiences by using Microsoft Xbox 360 Kinect sensor technology on computers running Windows 7. (defined by Microsoft) Links worth checking out: Download Kinect for Windows SDK beta – You can either download a 32 or 64 bit SDK depending on your OS. Readme for Kinect for Windows SDK Beta from Microsoft Research  Programming Guide: Getting Started with the Kinect for Windows SDK Beta Code Walkthroughs of the samples that ship with the Kinect for Windows SDK beta (Found in \Samples Folder) Coding4Fun Kinect Toolkit – Lots of extension methods and controls for WPF and WinForms. Kinect Mouse Cursor – Use your hands to control things like a mouse created by Brian Peek. Kinect Paint – Basically MS Paint but use your hands! Kinect for Windows SDK Quickstarts Installing and Using the Kinect Sensor Getting it installed: After downloading the Kinect SDK Beta, double click the installer to get the ball rolling. Hit the next button a few times and it should complete installing. Once you have everything installed then simply plug in your Kinect device into the USB Port on your computer and hopefully you will get the following screen: Once installed, you are going to want to check out the following folders: C:\Program Files (x86)\Microsoft Research KinectSDK – This contains the actual Kinect Sample Executables along with the documentation as a CHM file. Also check out the C:\Users\Public\Documents\Microsoft Research KinectSDK Samples directory: The main thing to note here is that these folders contain the source code to the applications where you can compile/build them yourself. Audio NUI DEMO Time Let’s get started with some demos. Navigate to the C:\Program Files (x86)\Microsoft Research KinectSDK folder and double click on ShapeGame.exe. Next up is SkeletalViewer.exe (image taken from http://www.i-programmer.info/news/91-hardware/2619-microsoft-launch-kinect-sdk-beta.html as I could not get a good image using SnagIt) At this point, you will have to download Kinect Mouse Cursor – This is really cool because you can use your hands to control the mouse cursor. I actually used this to resize itself. Last up is Kinect Paint – This is very cool, just make sure you read the instructions! MS Paint on steroids! A few tips for getting started building Kinect Applications. It appears WPF is the way to go with building Kinect Applications. You must also use a version of Visual Studio 2010.  Your going to need to reference Microsoft.Research.Kinect.dll when building a Kinect Application. Right click on References and then goto Browse and navigate to C:\Program Files (x86)\Microsoft Research KinectSDK and select Microsoft.Research.Kinect.dll. You are going to want to make sure your project has the Platform target set to x86. The Coding4Fun Kinect Toolkit really makes things easier with extension methods and controls. Just note that this is for WinForms or WPF. Conclusion It looks like we have a lot of fun in store with the Kinect SDK. I’m very excited about the release and have already been thinking about all the applications that I can begin building. It seems that development will be easier now that we have an official SDK and the great work from Coding4Fun. Please subscribe to my blog or follow me on twitter for more information about Kinect, Silverlight and other great technology.  Subscribe to my feed

  • Day 5 - Tada! My Game Menu Screen Graphics

    - by dapostolov
    So, tonight I took some time to mash up some graphics for my game menu screen. My artistic talent sucks...but here goes nothing...voila, my menu screen!! The Menu Screen The screen above is displaying 4 sprites, even though it looks like maybe 7... I guess one of the first things for me to test in the future is ... is it more memory efficient (and better frame rate) to draw one big background image OR tp paint the screen black, and place each sprite in set locations? To display the 4 sprites above, I borrowed my code from yesterday ... I know, tacky, but...I wanted to see it, feel it. Do you feel it? FEEL IT! (homer voice & shakes fist) Note: the menu items won't scale properly as it stands with this code, well pretty much they do nothing except look pretty... Paint.Net & Google Fun So how did I create that image above? Well, to create the background and 3 menu items I used Paint.Net. Basically, I scoured Google images for: a stone doorway, a stone pillar, an old book, a wizards hat, and...that's it pretty much it! I'll let you type in those searches and see if you can locate the images I used. I know, bad developer...but I figured since I modified the images considerably it doesn't count...well for a personal project it shouldn't count...*shrug* Anyhow, I extracted each key assest I wanted from each image and applied lots of matting, blurring, color changes, glow effects and such. Then, using my vivid imagination I placed / composed each of the layered assets into the mashed up the "scene" above. Pretty cool, eh? Hey, did you know, the cool mist effect is actually a fire rendition in Paint.net? I set it to black & white with opacity set next to nothing. I'm also very proud of the yellow "light" in the stone doorway. I drew that in and then applied gausian blur to it to give it the effect of light creeping out around the door and into the room...heheh. So did I achieve the dark, mysterious ritual as I stated in my design doc? I think I had a great stab at it! Maybe down the road I can get a real artist to crank out some quality graphics for the game... =) So, What's Next? Well, I don't have that animated brazier yet...however, I thought it would be even cooler if I can get that door pulsing that yellow light and it would be extremely cool to have the smoke / mist moving across the screen! Make the creative ideas stop!! (clutches head) haha! I'm having great fun working on this project =) I recommend others giving something like this a try, it's really fulfilling. OK. Tomorrow... I think I'm going to start creating some game / menu objects as per the design doc, maybe even get a custom mouse cursor up on the screen and handle a couple of mouse events, and lastly, maybe a feature to toggle a framerate display... D.

  • Adding visible "Markers" to represent Geopoints to a MapView using ItemizedOverlay in Android

    - by LordSnoutimus
    Hello, I am building an application which stores GPS locations in a SQLite database and then outputs the data onto a MapView using an Overlay by drawing a red line between the points. I want to be able to show graphical markers (images) for each of these points as well as the red line. My code is as follows: public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { populate(); points.addElement(point); } //public void setProjection(Projection projection) { // this.projection = projection; // } public void draw(Canvas canvas, MapView view, boolean shadow) { populate(); int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } } What would be the easiest way to implement adding markers for each GeoPoint? Thanks

  • Overlay only draws line between first 2 GPS points in Android

    - by LordSnoutimus
    Hi, I am experiencing an unusual error using ItemizedOverlay in Android. I am creating a GPS tracking device that plots a route between waypoints stored in a database. When I provide the first two sets of longitude and latitude points through the emulator in Eclipse, it draws a red line just how I want it, but if I send another GPS point, it animates to the point, but does not draw a line from the last point. public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { points.addElement(point); } public void draw(Canvas canvas, MapView view, boolean shadow) { int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } }

  • Is Google Analytics for Mobile available for Windows Mobile / Compact Framework

    - by Michal Drozdowicz
    Recently Google introduced an SDK for application usage tracking on mobile devices (Google Analytics for Mobile Apps). Unfortunately, it seems that it only supports IPhone and Android devices. Do you have any idea if this framework can somehow be used from Windows Mobile / Compact Framework applications or if Google is planning to release an SDK for WM? BTW, I don't mean a WM application for browsing through GA server reports, but an SDK for tracking your mobile app's usage.

  • Blackberry (Java) - Drawing graphics on top of rendered text/buttons etc

    - by paullb
    Based off the one of the demos I have the following code.

I would like both the text contents and the paint function contents to appear. Is this possible? public CityInfoScreen() { //invoke the MainScreen constructor super(); //add a screen title LabelField title = new LabelField("City Information Kiosk", LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH); setTitle(title); //add a text label add(new RichTextField("Major U.S. Cities")); //add a drop-down list with three choices: //Los Angeles, Chicago, or New York //...

  • Microsoft Word files have weird icons suddenly?

I can open the files just fine, and I tried restarting my computer, creating new files, clicking F5 on the desktop, turning off my Windows XP theme patcher, and none of them worked, any ideas? EDIT: I've also noticed that it happened to the following programs: Windows Live Messenger, iTunes, and Skype, so not just MS Office. Yet, some are still fine like IE, Paint, GIMP, Paint.NET, a few web browsers, etc.

  • How do I make Windows pbrush default to a save-as JPG format?

    - by nik
    Every time I want to save some image I paste into the Paint application, it chooses a BMP/DIB format (which is the worst for saving things from the clipboard). How can I hack this Windows pbrush application into defaulting to a JPEG format save always? If it matters I am using Windows XP SP3 and Paint 5.1 at the moment. But, I thought the hack would be generic, and I'd like to do this across all my Windows machines.

  • Onpaint events (invalidated) changing execution order after a period normal operation (runtime)

    - by Luke Mcneice
    I have 3 data graphs that are painted via the their paint events. When I have data that I need to insert into the graph I call the controls invalidate() command. The first control's paint event actually creates a bitmap buffer for the other 2 graphs to avoid repeating a long loop. So the invalidate commands are in a specific order (1,2,3). This works well, however when the graphed data reaches the end of the graph window (PictureBox) where the data would normally start scrolling, the paint events begin firing in the wrong order (2,3,1). has anyone came across this before? why might this be happening?

  • Drawing lines between views in a TableLayout

    - by RiThBo
    Firstly - sorry if you saw my other question which I deleted. My question was flawed. Here is a better version If I have two views, how do I draw a (straight) line between them when one of them is touched? The line needs to be dynamic so it can follow the finger until it reaches the second view where it "locks on". So, when view1 is touched a straight line is drawn which then follows the finger until it reaches view2. I created a LineView class that extends view, but I don't how to proceed. I read some tutorials but none show how to do this. I think I need to get the coordinates of both view, and then create a path which "updates" on MotionEvent. I can get the coordinates and the ids of the views I want to draw a line between, but the line that I try to draw between them either goes above it, or the line does not reach past the width and height of the view. Any advice/code/clarity would be much appreciated! Here is some code: My layout. I want to draw a line between two views contained in theTableLayout.# <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/activity_game_relative_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TableLayout android:layout_marginTop="35dp" android:layout_marginBottom="35dp" android:id="@+id/tableLayout1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" > <TableRow android:id="@+id/table_row_1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="5dip" > <com.example.view.DotView android:id="@+id/game_dot_1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="10dp" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_marginTop="10dp" /> <com.example.view.DotView android:id="@+id/game_dot_2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="10dp" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_marginTop="10dp" /> <com.example.view.DotView android:id="@+id/game_dot_3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="10dp" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_marginTop="10dp" /> </TableRow> <TableRow android:id="@+id/table_row_2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="5dip" > <com.example.view.DotView android:id="@+id/game_dot_7" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="10dp" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_marginTop="10dp" /> <com.example.view.DotView android:id="@+id/game_dot_8" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="10dp" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_marginTop="10dp" /> <com.example.dotte.DotView android:id="@+id/game_dot_9" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="10dp" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_marginTop="10dp" /> </TableRow> </TableLayout> </RelativeLayout> This is my LineView class. I use this to try and draw the actual line between the points. public class LineView extends View { Paint paint = new Paint(); float startingX, startingY, endingX, endingY; public LineView(Context context) { super(context); // TODO Auto-generated constructor stub paint.setColor(Color.BLACK); paint.setStrokeWidth(10); } public void setPoints(float startX, float startY, float endX, float endY) { startingX = startX; startingY = startY; endingX = endX; endingY = endY; invalidate(); } @Override public void onDraw(Canvas canvas) { canvas.drawLine(startingX, startingY, endingX, endingY, paint); } } And this is my Activity. public class Game extends Activity { DotView dv1, dv2, dv3, dv4, dv5, dv6, dv7; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_game); getWindow().getDecorView().setSystemUiVisibility( View.SYSTEM_UI_FLAG_LOW_PROFILE); findDotIds(); RelativeLayout rl = (RelativeLayout) findViewById(R.id.activity_game_relative_layout); LineView lv = new LineView(this); lv.setPoints(dv1.getLeft(), dv1.getTop(), dv7.getLeft(), dv7.getTop()); rl.addView(lv); // TODO: Get the coordinates of all the dots in the TableLayout. Use view tree observer. } private void findDotIds() { // TODO Auto-generated method stub dv1 = (DotView) findViewById(R.id.game_dot_1); dv2 = (DotView) findViewById(R.id.game_dot_2); dv3 = (DotView) findViewById(R.id.game_dot_3); dv4 = (DotView) findViewById(R.id.game_dot_4); dv5 = (DotView) findViewById(R.id.game_dot_5); dv6 = (DotView) findViewById(R.id.game_dot_6); dv7 = (DotView) findViewById(R.id.game_dot_7); } } The views I want to draw lines between are in the TableLayout.

  • How could I evaluate this in code?

    - by WM
    There is a medieval puzzle about an old woman and a basket of eggs. On her way to market, a horseman knocks down the old woman and all the eggs are broken. The horseman will pay for the eggs, but the woman does not remember the exact number she had, only that when she took the eggs in pair, there was one left over; similarly, there was one left over when she took them three or five at a time. When she took them seven at a time, however, none were left. Write an application that can determine the smallest number of eggs the woman could have had. It might be a multiple of seven because there are no eggs left when it's seven at a time. But I have a problem. 49 eggs -1=2*24 49 eggs -1=3*16 49 eggs-4=5*9 49 eggs-0=7*7
