  • Customize the Background in Boxee

    - by DigitalGeekery
    Are you a Boxee user who thinks the default background is little boring? Today we’ll take a look at how to freshen up the look of Boxee by changing the background. Boxee Background When you log into Boxee, select the Settings button at the upper left corner of the Home page.   Select General on the Settings screen. When you select or hover your mouse over the Background Image button, you’ll see options to set a background image or set a background image folder. You’ll have the option of settings a single static image as your background, or choosing an images folder.   If you choose a folder, Boxee will rotate through the images in the folder. To set Background images folder, select that option. Browse for your image folder.. And then select OK.   Boxee will rotate through the images in the folder.   Images will change every ten seconds.   If you prefer a single static image, select Set background image   Choose a image and select OK. Now just enjoy you nice new backgrounds.   If you ever wish to revert back to the default Boxee background, simply select Reset Images on the Settings \ General screen. Adding your own backgrounds is a nice way to customize your Boxee experience. Ideally, you’ll want to choose high resolution images and images oriented as landscape rather than portrait. If you are unfamiliar with Boxee, check out our article on getting started with Boxee.  Looking for a Boxee remote? Read how to use your iPhone or iPod Touch as a Boxee remote.

  • Looking for mass cropping software

    - by Bart van Heukelom
    I'm looking for a tool than runs on Ubuntu that can let me: Open an image in a folder which has thousands Crop and rotate it Save as a copy, automatically named (not manually), with one click. Preferably with something in the name that I can later use to filter these cropped copies in Nautilus (unless it saves in another directory, that'd be even better). Move to next image and repeat Does it exist?

  • Multi-touch mouse gestures in Ubuntu 13.10?

    - by Alex Li
    I have Ubuntu 13.10 and Windows 8 installed as dual boot. There is a mousepad specific driver in Windows 8 that lets me use multi-touch gestures such as two finger swipe to go back/forward, pinch to zoom in/out, and pivot rotate. The driver/touchpad is made by Alps. But on Ubuntu 13.10 there is no multi-touch support like those I can use on Windows. How can I get the same mouse gestures on Windows to work on Ubuntu 13.10?

  • Creating predefinied camera views - How do I move the camera to make sense while using Controller?

    - by Deukalion
    I'm trying to understand 3D but the one thing I can't seem to understand is the Camera. Right now I'm rendering four 3D Cubes with textures and I set the Project Matrix: public BasicCamera3D(float fieldOfView, float aspectRatio, float clipStart, float clipEnd, Vector3 cameraPosition, Vector3 cameraLookAt) { projection_fieldOfView = MathHelper.ToRadians(fieldOfView); projection_aspectRatio = aspectRatio; projection_clipstart = clipStart; projection_clipend = clipEnd; matrix_projection = Matrix.CreatePerspectiveFieldOfView(projection_fieldOfView, aspectRatio, clipStart, clipEnd); view_cameraposition = cameraPosition; view_cameralookat = cameraLookAt; matrix_view = Matrix.CreateLookAt(cameraPosition, cameraLookAt, Vector3.Up); } BasicCamera3D gameCamera = new BasicCamera3D(45f, GraphicsDevice.Viewport.AspectRatio, 1.0f, 1000f, new Vector3(0, 0, 8), new Vector3(0, 0, 0)); This creates a sort of "Top-Down" camera, with 8 (still don't get the unit type here - it's not pixels I guess?) But, if I try to position the camera at the side to make "Side-View" or "Reverse Side View" camera, the camera is rotating to much until it's turned around it a couple of times. I render the boxes at: new Vector3(-1, 0, 0) new Vector3(0, 0, 0) new Vector3(1, 0, 0) new Vector3(1, 0, 1) and with the Top-Down camera it shows good, but I don't get how I can make the camera show the side or 45 degrees from top (Like 3rd person action games) because the logic doesn't make sense. Also, since every object you render needs a new BasicEffect with a new projection/view/world - can you still use the "same" camera always so you don't have to create a new View/Matrix and such for each object. It's seems weird. If someone could help me get the camera to navigate around my objects "naturally" so I can be able to set a few predtermined views to choose from it would be really helpful. Are there some sort of algorithm to calculate the view for this and perhaps not simply one value? Examples: Top-Down-View: I have an object at 0, 0, 0 when I turn the right stick on the Xbox 360 Controller it should rotate around that object kind of, not flip and turn upside down, disappear and then magically appear as a tiny dot somewhere I have no clue where it is like it feels like it does now. Side-View: I have an object at 0, 0, 0 when I rotate to sides or up and down, the camera should be able to show a little more of the periphery to each side (depending on which you look at), and the same while moving up or down.

  • GLM Velocity Vectors - Basic Maths to Simulate Steering

    - by Reanimation
    UPDATE - Code updated below but still need help adjusting my math. I have a cube rendered on the screen which represents a car (or similar). Using Projection/Model matrices and Glm I am able to move it back and fourth along the axes and rotate it left or right. I'm having trouble with the vector mathematics to make the cube move forwards no matter which direction it's current orientation is. (ie. if I would like, if it's rotated right 30degrees, when it's move forwards, it travels along the 30degree angle on a new axes). I hope I've explained that correctly. This is what I've managed to do so far in terms of using glm to move the cube: glm::vec3 vel; //velocity vector void renderMovingCube(){ glUseProgram(movingCubeShader.handle()); GLuint matrixLoc4MovingCube = glGetUniformLocation(movingCubeShader.handle(), "ProjectionMatrix"); glUniformMatrix4fv(matrixLoc4MovingCube, 1, GL_FALSE, &ProjectionMatrix[0][0]); glm::mat4 viewMatrixMovingCube; viewMatrixMovingCube = glm::lookAt(camOrigin, camLookingAt, camNormalXYZ); vel.x = cos(rotX); vel.y=sin(rotX); vel*=moveCube; //move cube ModelViewMatrix = glm::translate(viewMatrixMovingCube,globalPos*vel); //bring ground and cube to bottom of screen ModelViewMatrix = glm::translate(ModelViewMatrix, glm::vec3(0,-48,0)); ModelViewMatrix = glm::rotate(ModelViewMatrix, rotX, glm::vec3(0,1,0)); //manually turn glUniformMatrix4fv(glGetUniformLocation(movingCubeShader.handle(), "ModelViewMatrix"), 1, GL_FALSE, &ModelViewMatrix[0][0]); //pass matrix to shader movingCube.render(); //draw glUseProgram(0); } keyboard input: void keyboard() { char BACKWARD = keys['S']; char FORWARD = keys['W']; char ROT_LEFT = keys['A']; char ROT_RIGHT = keys['D']; if (FORWARD) //W - move forwards { globalPos += vel; //globalPos.z -= moveCube; BACKWARD = false; } if (BACKWARD)//S - move backwards { globalPos.z += moveCube; FORWARD = false; } if (ROT_LEFT)//A - turn left { rotX +=0.01f; ROT_LEFT = false; } if (ROT_RIGHT)//D - turn right { rotX -=0.01f; ROT_RIGHT = false; } Where am I going wrong with my vectors? I would like change the direction of the cube (which it does) but then move forwards in that direction.

  • Rotating Oracle Database's Alert Log with ADRCI

    Many Oracle database administrators would not only like to report on (ORA-) errors but also manage the alert log itself--saving and/or trimming the alert log, aka alert log rotation. Oracle's new ADR with command interface can easily be used to help rotate Oracle's alert log.

  • Smooth pixels while rotating sprite

    - by goodm
    I just started with andengine, so this maybe gonna be silly question. How to make my sprites more smooth while I rotate them? Or maybe it because this is screenshot from tablet? Thanks JohnEye it works: Just need to change my BitmapTextureAtlas from: BitmapTextureAtlas carAtlas = new BitmapTextureAtlas(this.getTextureManager(),100, 63); to: BitmapTextureAtlas carAtlas = new BitmapTextureAtlas(this.getTextureManager(),100, 63, TextureOptions.BILINEAR);

  • Displaylink USB show "Logo / Loading" on monitor

    - by Ken Le
    I tried with this problem for 2 years already. LOL, today, I install Ubuntu for I have to resolve it or I will back to stupid Windows 7. First, I have 3 monitors. My graphic card is support dual ( ATI Radeon ), so I have no problem on extend those multi monitor on VGA and DVI. The 3rd monitor is Displaylink USB. After installed everything required, when I reboot, the displaylink monitor show "Ubuntu ...." like logo / loading screen. I go to System Display , Detect monitor, it only show my 1st and 2nd, NO 3RD Displaylink. I can move my mouse between those 1st & 2nd, but the 3rd is only show the Ubuntu Screen. I press Ctrl+Alt+1, then screen switch to Displaylink USB 3RD monitor, but its "Terminal" not a desktop. Then I press Ctrl+Alt+7 , the screen switch back to my 1st, 2nd, and the displaylink 3rd is witch back to Logo / Ubuntu again.

  • Quaternion based rotation and pivot position

    - by Michael IV
    I can't figure out how to perform matrix rotation using Quaternion while taking into account pivot position in OpenGL.What I am currently getting is rotation of the object around some point in the space and not a local pivot which is what I want. Here is the code [Using Java] Quaternion rotation method: public void rotateTo3(float xr, float yr, float zr) { _rotation.x = xr; _rotation.y = yr; _rotation.z = zr; Quaternion xrotQ = Glm.angleAxis((xr), Vec3.X_AXIS); Quaternion yrotQ = Glm.angleAxis((yr), Vec3.Y_AXIS); Quaternion zrotQ = Glm.angleAxis((zr), Vec3.Z_AXIS); xrotQ = Glm.normalize(xrotQ); yrotQ = Glm.normalize(yrotQ); zrotQ = Glm.normalize(zrotQ); Quaternion acumQuat; acumQuat = Quaternion.mul(xrotQ, yrotQ); acumQuat = Quaternion.mul(acumQuat, zrotQ); Mat4 rotMat = Glm.matCast(acumQuat); _model = new Mat4(1); scaleTo(_scaleX, _scaleY, _scaleZ); _model = Glm.translate(_model, new Vec3(_pivot.x, _pivot.y, 0)); _model =rotMat.mul(_model);//_model.mul(rotMat); //rotMat.mul(_model); _model = Glm.translate(_model, new Vec3(-_pivot.x, -_pivot.y, 0)); translateTo(_x, _y, _z); notifyTranformChange(); } Model matrix scale method: public void scaleTo(float x, float y, float z) { _model.set(0, x); _model.set(5, y); _model.set(10, z); _scaleX = x; _scaleY = y; _scaleZ = z; notifyTranformChange(); } Translate method: public void translateTo(float x, float y, float z) { _x = x - _pivot.x; _y = y - _pivot.y; _z = z; _position.x = _x; _position.y = _y; _position.z = _z; _model.set(12, _x); _model.set(13, _y); _model.set(14, _z); notifyTranformChange(); } But this method in which I don't use Quaternion works fine: public void rotate(Vec3 axis, float angleDegr) { _rotation.add(axis.scale(angleDegr)); // change to GLM: Mat4 backTr = new Mat4(1.0f); backTr = Glm.translate(backTr, new Vec3(_pivot.x, _pivot.y, 0)); backTr = Glm.rotate(backTr, angleDegr, axis); backTr = Glm.translate(backTr, new Vec3(-_pivot.x, -_pivot.y, 0)); _model =_model.mul(backTr);///backTr.mul(_model); notifyTranformChange(); }

  • How to use uTouch on multitouch-enabled touchpads?

    - by Freddi
    I currently have a Synaptics touchpad with only few classic multitouch features (2 finger scroll, right click). By installing the uTouch testing suite, I saw that it doesn't accept my touchpad as input device. I want to buy a newer notebook and would like to benefit of uTouch features (window management, swipe, pinch, rotate). Does uTouch only work on touchscreens or also on touchpads? What requirements should I take into account when choosing a new notebook?

  • How do you demonstrate performance in paired-programming environments?

    - by NT3RP
    Performance reviews have come up recently at my work, and I was put in an interesting position. Our team does a lot of pair programming, which has a tendency of averaging out the skill differences between team members (especially considering we rotate pairs). Generally, when doing performance reviews, you look back at the work you've done, and demonstrate what you've accomplished, and how you've exceeded expectations to try to negotiate a raise or other benefits. How do you demonstrate (or even measure) individual performance in an environment like this?

  • Unit turning in navmesh-based pathfinding

    - by Haddayn
    I'm working on an RTS game, and I'm using navmeshes for unit pathfinding. I do know how to find a general path within a navmesh, but how do you determine if the unit have enough space to turn? I have units of different shapes (mostly rectangles with different dimensions), and with different turn radii. Additionally some of units can turn in place, and some can move in reverse. So, how to find a path which unit can follow, considering that it can not rotate easily?

  • Fastest way to check if two square 2D arrays are rotationally and reflectively distinct

    - by kustrle
    The best idea I have so far is to rotate first array by {0, 90, 180, 270} degrees and reflect it horizontally or/and vertically. We basically get 16 variations [1] of first array and compare them with second array. if none of them matches the two arrays are rotationally and reflectively distinct. I am wondering if there is more optimal solution than this brute-force approach? [1] 0deg, no reflection 0deg, reflect over x 0deg, reflect over y 0deg, reflect over x and y 90deg, no reflection ...

  • Supermicro X8SIL-F with Enermax Modu82+ 625W PSU booting issue

    - by Richard Whitman
    I am assembling a custom PC. The configuration is below: Motherboard: Supermicro X8SIL-F Processor: Intel Xeon 3430 Power Supply: Enermax Modu82+ 625W. Memory: Kingston KVR1333D3LQ8R9S/8GEC 8GBx1 installed in DimmA1 This power switch: Frozen CPU switch When I turn on the PSU, the motherboard tries to start itself before I even push the power switch. The following happens: The CPU fan rotates like once or twice, and then stops. After 1-2 seconds, the CPU fan tries to rotate again and stops after about one or two rotations. Finally, after another 1-2 seconds, it again starts and this time it rotates for about 3-4 seconds before stopping. If I pull out the Power switch, and turn on the PSU, again the MB turns on itself and the following happens: The CPU fan rotates like once or twice, and then stops. After 1-2 seconds, the CPU fan tries to rotate again and stops after about one or two rotations. Finally, after another 1-2 seconds, it again starts and the system boots properly I am sure there is nothing wrong with any of the components, because I have two sets of identical components (2 MBs, 2 CPUs, 2 PSUs, 2 switches and so on). And both of the systems show the same symptoms. Why is the MB booting up by itself? Why does it fail to boot when the Power Switch is installed? Is something wrong with the type of Power Switch I am using? PS: the power switch is installed correctly, I have double checked the MB manual to make sure its connecting the right pins.

  • How to convert JPEG JFIF files to JPEG Exif format?

    - by tigrou
    I recently put the SD card of my camera in a Windows 7 PC and start browsing pictures on it. I noticed some were not aligned correctly and use rotate feature included in Windows Photo Viewer in order to view them as I wanted. What I didn't know is that when rotate feature is used, it also overwrite the picture when pressing next or previous button resulting in a possible loss of quality (which is in my opinion a bad idea, app should at least warn user of what will happened when using such a feature). After that, I re-inserted the SD card back in my camera and bad surprise happened : the rotated picture could not be previewed anymore. Instead, i got a black screen saying "Incompatible JPEG format". Other files (untouched) are still working ok. To try to understand what happened I opened a JPEG file from camera and one generated on windows 7 in a hex editor. Here is the difference : The camera JPEG files have a Exif tag in them (with 0xE1 in header). Other JPEG files (Windows 7) have first a JFIF tag in it, followed by a Exif tag (with 0xE0 in header). So if i understand it well, both are JPEG files, but using a different internal format. Here is my question : is it possible (using some tool) to convert JFIF files to Exif format ? I understand that original camera files have been reencoded and thus lose some quality (getting originals back is impossible). What i want know if convert them from JFIF back to Exif (without a second loss of quality if possible...)

    I see only two files maillog and maillog.1 in /var/log. grepping for maillog in logrotate.d directory gives three files that have a mention of maillog. syslog /var/log/messages /var/log/secure /var/log/maillog /var/log/spooler /var/log/boot.log /var/log/cron { #/var/log/messages /var/log/secure /var/log/spooler /var/log/boot.log /var/log/cron { daily sharedscripts postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true endscript } syslog-ng /var/log/messages /var/log/secure /var/log/maillog /var/log/spooler /var/log/boot.log /var/log/cron /var/log/kern.log /var/log/kern { sharedscripts postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true endscript } and maillog. /var/log/maillog { daily compress # rotate 365 rotate 14 sharedscripts postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true endscript } I am new to logrotate so may be I am missing something obvious. What can be the issue? The setup was already done when I started managing the server so I don't also know as do why do I have 3 mentions for maillog in logrotate.

  • Apache, logerror and logrotate: what is the best method?

    - by OlivierDofus
    Hi! Here's a vhost example of my sites: <VirtualHost *:80> DocumentRoot /datas/web/woog ServerName woog.com ServerAlias www.woog.com ErrorLog "|/httpd-2.2.8/bin/rotatelogs /logs/woog/error_log 86400" CustomLog "|/httpd-2.2.8/bin/rotatelogs /logs/woog/access_log 86400" combined DirectoryIndex index.php index.htm <Location /> Allow from All </Location> <Directory /*> Options FollowSymLinks AllowOverride Limit AuthConfig </Directory> </VirtualHost> I've got 12 sites running now. This gives something like: [Shake]:/sources/software/mod_log_rotate# ps x | grep rotate /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/error_log 86400 /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/error_log 86400 [snap (as many error_log as virtual hosts)] /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/access_log 86400 /httpd-2.2.8/bin/rotatelogs /logs/[hidden siteweb]/access_log 86400 [snap (as many access_log as virtual hosts)] grep rotate [Shake]:/sources/software/mod_log_rotate# !!! I've been looking everywhere but I've only found mod_log_rotate. The "little" problem is that the author (very good C developper) explains: "Unfortunately Apache error logs are handled in such a way that we can't work the same log rotation magic on them. Like transfer logs they support piped logging though so you can still use rotatelogs for them. " So my question is: what would be the best way to handle multiple logs? If I just do a very classical log and I use the system's "logrotate" program couldn't this be a good deal? How would/do you deal with that? Thank you!

  • Concatenating gziped Apache logs

    - by markdrayton
    We rotate and compress our Apache logs each day but it's become apparent that this isn't frequently enough. An uncompressed log is about 6G, which is getting close to filling our log partition (yep, we'll make it bigger in the future!) as well as taking a lot of time and CPU to compress each day. We have to produce a gziped log for each day for our stats processing. Obviously we could move our logs to a partition with more space but I also want to spread the compression overhead throughout the day. Using Apache's rotatelogs we can rotate and compress the log more often -- hourly, say -- but how can I concatenate all the hourly compressed logs into a running compressed log for the day, without decompressing the previous logs? I don't want to uncompress 24 hours' worth of data and recompress it because that has all the disadvantages of our current solution. Gzip doesn't seem to offer any append or concatenate option but perhaps I've missed something obvious. This question suggests straight shell concatenation "works" in that the archive can be decompressed but that gzip -l doesn't work seems a bit dodgy. Alternatively, perhaps this is still a bad way to do things. Other suggestions are welcome -- our only constraints are our relatively small log partitions and the need to provide a daily compressed log.
