  • How to delete/edit files from readonly filesystem

    - by Santosh Linkha
    I am having problem with my memory device (actually a memory card that act external memory device like pendrive). experimentx@workmateX:/var/www/zendtest$ sudo rm /media/A88F-8788/python-2.7.1-docs-html.zip rm: cannot remove `/media/A88F-8788/python-2.7.1-docs-html.zip': Read-only file system I tried to change the file permission of the system but that doesn't work experimentx@workmateX:/var/www/zendtest$ sudo chmod 0777 /media/A88F-8788/python-2.7.1-docs-html.zip chmod: changing permissions of `/media/A88F-8788/python-2.7.1-docs-html.zip': Read-only file system But it perfectly works on windows.

  • Setting up OpenGL camera with off-center perspective

    - by user5484
    Hi, I'm using OpenGL ES (in iOS) and am struggling with setting up a viewport with an off-center distance point. Consider a game where you have a character in the left hand side of the screen, and some controls alpha'd over the left-hand side. The "main" part of the screen is on the right, but you still want to show whats in the view on the left. However when the character moves "forward" you want the character to appear to be going "straight", or "up" on the device, and not heading on an angle to the point that is geographically at the mid-x position in the screen. Here's the jist of how i set my viewport up where it is centered in the middle: // setup the camera // glMatrixMode(GL_PROJECTION); glLoadIdentity(); const GLfloat zNear = 0.1; const GLfloat zFar = 1000.0; const GLfloat fieldOfView = 90.0; // can definitely adjust this to see more/less of the scene GLfloat size = zNear * tanf(DEGREES_TO_RADIANS(fieldOfView) / 2.0); CGRect rect; rect.origin = CGPointMake(0.0, 0.0); rect.size = CGSizeMake(backingWidth, backingHeight); glFrustumf(-size, size, -size / (rect.size.width / rect.size.height), size / (rect.size.width / rect.size.height), zNear, zFar); glMatrixMode(GL_MODELVIEW); // rotate the whole scene by the tilt to face down on the dude const float tilt = 0.3f; const float yscale = 0.8f; const float zscale = -4.0f; glTranslatef(0.0, yscale, zscale); const int rotationMinDegree = 0; const int rotationMaxDegree = 180; glRotatef(tilt * (rotationMaxDegree - rotationMinDegree) / 2, 1.0f, 0.0f, 0.0f); glTranslatef(0, -yscale, -zscale); static float b = -25; //0; static float c = 0; // rotate by to face in the direction of the dude float a = RADIANS_TO_DEGREES(-atan2f(-gCamera.orientation.x, -gCamera.orientation.z)); glRotatef(a, 0.0, 1.0, 0.0); // and move to where it is glTranslatef(-gCamera.pos.x, -gCamera.pos.y, -gCamera.pos.z); // draw the rest of the scene ... I've tried a variety of things to make it appear as though "the dude" is off to the right: - do a translate after the frustrum to the x direction - do a rotation after the frustrum about the up/y-axis - move the camera with a biased lean to the left of the dude Nothing i do seems to produce good results, the dude will either look like he's stuck on an angle, or the whole scene will appear tilted. I'm no OpenGL expert, so i'm hoping someone can suggest some ideas or tricks on how to "off-center" these model views in OpenGL. Thanks!

  • Error correlation ID when trying to create a BI center site in Sharepoint 2010

    - by Patrick Olurotimi Ige
    Before you get to see the template to install the BI center site you will have to activate the PerformancePoint Services Site Collection Features from the : Site Collection Administration  > site collection features But after i activated it and try to create a site i get correlation error bla bla... After looking at the ULS log files i saw something related to not being able to use the SharePoint Server Publishing. So i went to the collection features and activate the SharePoint Server Publishing Infrastructure I could create a BI site

  • Can't Install php5-dev on Ubuntu 12.04 running OpenVZ

    - by MEsch
    I'm trying to fetch the php apc package using pecl and running into a problem that I believe may be caused by OpenVZ. To do so I need php5-dev. When I try to install it via apt-get, I get this: php5-dev : Depends: libssl-dev but it is not going to be installed Depends: libtool (>= 2.2) but it is not going to be installed As I try to manually install dependencies (without success), I believe I've identified libc6-dev as the culprit. libc6-dev : Depends: libc6 (= 2.15-0ubuntu10.2) but 2.15-0ubuntu10+openvz0 is to be installed I have libc6 installed on the system. If it's any help here is my sources.list: deb http://archive.ubuntu.com/ubuntu precise main restricted universe deb http://archive.ubuntu.com/ubuntu precise-updates main restricted universe deb http://security.ubuntu.com/ubuntu precise-security main restricted universe multiverse deb http://archive.canonical.com/ubuntu precise partner This is a very frustrating problem, as I have other instances of Ubuntu 12.04 running just fine elsewhere (though not on OpenVZ).

    Hey guys, I am a software developer since 8 years. I do around 20 projects, some smaller, some bigger. I know to help myself trough magic google, msdn, youttube, tutorials, howTows etc. I play around with the idea to get a friend of mine (who is soft-dev since 5 years) and begin my own software-developer-company. What do you think are the preconditions to get from a freelancer to his own little company with 2-3 employees?

  • System Settings and Software Center does not pull up after fresh install 11.10 amd64

    - by hydroparadise
    I've had a few install rounds with ubuntu ever since 8.04 and has worked flawlessly every time. However, for some reason, when I try to click either System Settings or Software Center, the icon pulses as if it were working to come up but never does. The same goes for System Settings. I would expect that a password dialog would appear, but nothing shows. Is there bug with 11.10 that didn't exist with 11.04?

  • How do I properly center Nifty GUI elements on screen?

    - by Jason Crosby
    I am new to JME3 game engine but I know Android XML GUI layouts pretty good. I have a simple layout here and I cant figure out what is wrong. Here is my XML code: <?xml version="1.0" encoding="UTF-8"?> <nifty xmlns="http://nifty-gui.sourceforge.net/nifty-1.3.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://nifty-gui.sourceforge.net/nifty-1.3.xsd http://nifty-gui.sourceforge.net/nifty-1.3.xsd"> <useControls filename="nifty-default-controls.xml" /> <useStyles filename="nifty-default-styles.xml" /> <screen id="start" controller="com.jasoncrosby.game.farkle.gui.MenuScreenGui"> <layer id="layer" backgroundColor="#66CD00" childLayout="center"> <panel id="panel" align="center" valign="center" childLayout="center" visibleToMouse="true"> <image filename="Textures/wood_floor.png" height="95%" width="95%"/> <panel id="panel" align="center" valign="center" childLayout="center" visibleToMouse="true"> <text text="test" font="Interface/Fonts/Eraser.fnt"></text> </panel> </panel> </layer> </screen> Everything works well until I get to displaying the text. I have tried different alignments and tried moving the text into different panels but no matter what I do the text is never in the center of the screen. It's always in the upper left corner, so far I can only see the lower right part of the text. How can I center the text element in the center of the screen?
