  • How can I get Xubuntu's workspace switcher to show the proper sized desktop?

    - by Jennifer Jones
    I recently installed the Xubuntu desktop over my Ubuntu 12.04 installation, and have been customizing it to my liking. My laptop comes to class with me, and when it's not out of the room, it's usually connected to a second monitor. When I am not connected to the monitor, the workspace switcher shows that my windows are all inside about half of each workspace, but there's only one monitor connected. I'm looking for a way to get it to show workspaces that are reminiscent of this monitor's size and nothing more. Is there a way to fix that? I can attach a picture of the problem if necessary.

  • Tip #15: How To Debug Unit Tests During Maven Builds

    - by ByronNevins
    It must be really really hard to step through unit tests in a debugger during a maven build.  Right? Wrong! Here is how i do it: 1) Set up these environmental variables: MAVEN_OPTS=-Xmx1024m -Xms256m -XX:MaxPermSize=512mMAVEN_OPTS_DEBUG=-Xmx1024m -Xms256m -XX:MaxPermSize=512m  -Xdebug (no line break here!!)  -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9999MAVEN_OPTS_REG=-Xmx1024m -Xms256m -XX:MaxPermSize=512m 2) create 2 scripts or aliases like so:  maveny.bat: set MAVEN_OPTS=%MAVEN_OPTS_DEBUG% mavenn.bat: set MAVEN_OPTS=%MAVEN_OPTS_REG%    To debug do this: run maveny.bat run mvn install attach your debugger to port 9999 (set breakpoints of course) When maven gets to the unit test phase it will hit your breakpoint and wait for you. When done debugging simply run mavenn.bat Notes If it takes a while to do the build then you don't really need to set the suspend=y flag. If you set the suspend=n flag then you can just leave it -- but only one maven build can run at a time because of the debug port conflict.

    - by Hamish Hagaheygui
    Hi there, sorry im new here but i have a serious problem; I changed the CSS style sheet for IE7 for my site http://bumblebbids.com , but now when using IE7 it has no graphics and all of the scripts code is printed ; I have tried replacing the original stylesheet but it made no difference, so please suggest ways that i can fix this? If not, would it be possible to have a 'Incompatible browser' message that only appears for IE7 users? Thanks

  • Packages organisation with MVC design pattern

    - by Oltarus
    I have been programming quite a lot now and still can't decide which of these packages hierachies was the best: package1 Class1Controller Class1Model Class1View package2 Class2Controller Class2Model Class2View or controller Class1Controller Class2Contoller model Class1Model Class2Model view Class1View Class2View In other words, is it better to apply the MVC design pattern to classes or to packages? Is there any reason to choose one over the other? My question is language-agnostic, but I'm mostly a Java programmer, if it does any difference.

  • Why Real Web Developers Don't Use DreamWeaver

    We know there are Web Designers and there are Web Developers, and that they are very different animals altogether (check out our article on the difference between Web Designers and Web Developers), but they both, naturally, have a pride in what they do. A Web Developer derives his or her pride from staying on concept and delivering a website which performs as quickly as it possibly can. It's in the developers interest to make sure the pages s/he develops use as little of the resources available as possible.

  • ejabberd starts slow and fails

    - by Michael Tanner
    I installed ejabberd and tried to set it up. On my server there are strict rules which allow only several services and denies everything else. I experienced starting problems with my iptables rules and found out that ejabberd works when I allow everything in the iptables and restore my rules afterwards. Then it also works for connecting, registering and else. What could be the problem in my rules? Attached here: http://fixee.org/paste/s5s744j/ Would be nice to get a correction straight on fixee if I made a mistake. Thanks in advance. Edit 1: In the log files there are no specific error messages during startup.

  • Bullet Physics - Casting a ray straight down from a rigid body (first person camera)

    - by Hydrocity
    I've implemented a first person camera using Bullet--it's a rigid body with a capsule shape. I've only been using Bullet for a few days and physics engines are new to me. I use btRigidBody::setLinearVelocity() to move it and it collides perfectly with the world. The only problem is the Y-value moves freely, which I temporarily solved by setting the Y-value of the translation vector to zero before the body is moved. This works for all cases except when falling from a height. When the body drops off a tall object, you can still glide around since the translate vector's Y-value is being set to zero, until you stop moving and fall to the ground (the velocity is only set when moving). So to solve this I would like to try casting a ray down from the body to determine the Y-value of the world, and checking the difference between that value and the Y-value of the camera body, and disable or slow down movement if the difference is large enough. I'm a bit stuck on simply casting a ray and determining the Y-value of the world where it struck. I've implemented this callback: struct AllRayResultCallback : public btCollisionWorld::RayResultCallback{ AllRayResultCallback(const btVector3& rayFromWorld, const btVector3& rayToWorld) : m_rayFromWorld(rayFromWorld), m_rayToWorld(rayToWorld), m_closestHitFraction(1.0){} btVector3 m_rayFromWorld; btVector3 m_rayToWorld; btVector3 m_hitNormalWorld; btVector3 m_hitPointWorld; float m_closestHitFraction; virtual btScalar addSingleResult(btCollisionWorld::LocalRayResult& rayResult, bool normalInWorldSpace) { if(rayResult.m_hitFraction < m_closestHitFraction) m_closestHitFraction = rayResult.m_hitFraction; m_collisionObject = rayResult.m_collisionObject; if(normalInWorldSpace){ m_hitNormalWorld = rayResult.m_hitNormalLocal; } else{ m_hitNormalWorld = m_collisionObject->getWorldTransform().getBasis() * rayResult.m_hitNormalLocal; } m_hitPointWorld.setInterpolate3(m_rayFromWorld, m_rayToWorld, m_closestHitFraction); return 1.0f; } }; And in the movement function, I have this code: btVector3 from(pos.x, pos.y + 1000, pos.z); // pos is the camera's rigid body position btVector3 to(pos.x, 0, pos.z); // not sure if 0 is correct for Y AllRayResultCallback callback(from, to); Base::getSingletonPtr()->m_btWorld->rayTest(from, to, callback); So I have the callback.m_hitPointWorld vector, which seems to just show the position of the camera each frame. I've searched Google for examples of casting rays, as well as the Bullet documentation, and it's been hard to just find an example. An example is really all I need. Or perhaps there is some method in Bullet to keep the rigid body on the ground? I'm using Ogre3D as a rendering engine, and casting a ray down is quite straightforward with that, however I want to keep all the ray casting within Bullet for simplicity. Could anyone point me in the right direction? Thanks.

  • ubuntu 12.04 nvidia breaks resolution

    - by Terje Kristiansen
    i am running ubuntu 12.04 64-bit and i have a nvidia Geforce GT 650m, it was running fine with 1920 x 1024, except a lot of tearing everytime i ran videos. I thought activating the nvidia driver maybe would fix this. When entering "nvidia X server setting" it says " you do not appear to be using nvidia X driver. Please edit your X configuration file ( just run "nvidia-xconfig" as root), and restart the X server. I did and then the computer reboots with a resolutioin of 640 x 480. How can i restore the previous settings, or preferably get it to show full resolution without tearing ? When i enter "nvidia X Server Settings" now it still says the same as above, " do not appear to be using nvidia X driver" when i go to "system settings, additional drivers" it says nvidia_current -- "This driver is activated but not currently in use" astr0

  • Take Snapshots of Your Favorite Movie Scenes in VLC

    - by DigitalGeekery
    Have you ever wanted to grab a screenshot of your favorite TV or movie scene? Today we’ll show you how to do so with VLC Media Player. If you don’t have it already, download and install the latest version of VLC (link below). Start playing your movie, and to grab a snapshot, select Video from the menu and click Snapshot.   When you take a snapshot, by default a preview is displayed at the top left and the folder where the file is saved is briefly displayed on the screen. If you enable the Advanced Controls, you can take a snapshot with a click of a button, and advance the video frame by frame to get a more accurate shot. To enable the Advanced Controls, select View and Advanced Controls.   You’ll see the Advanced Controls buttons appear below the slider. Now just click on the Snapshot button to grab an image.   You can more easily control the frame you wish to grab by pressing the Frame by Frame button. You can pause the movie when it is near the perfect spot for your snapshot, and then press the Frame by Frame button to advance a single frame at a time. By default, the snapshots are saved as PNG files in your My Pictures folder in Windows. You can change those setting in the Preferences. First, you’ll need to select All under Show settings at the bottom. Then click on Video on the left. Scroll down a bit and you’ll see the Snapshot section. Here you can change the format from PNG to JPG, change the directory to which the snapshots are stored, turn on and off the preview, and change the filename prefix. Click Save when finished.   Now you have nice screenshots of your favorite movie to display as you wish…such as a Desktop Background!   VLC is an excellent media player that runs on Windows, Mac, and Linux. In addition to playing almost any media file, it also makes grabbing screenshots of your videos a breeze. Want to know more about VLC?

  • Upgrading from Express Edition to Standard Edition

    - by TiborKaraszi
    Say you encounter an SQL Server which is Express Edition, and it really should have been some higher edition. Sounds familiar? It is common for me as a consultant to find plenty of SQL Servers at a customer's site. Many of the databases in these will be moved (typically using backup and restore) to a "real" SQL Server. But in some cases, this might not be desirable. You want to convert the whole instance, from Express to a "real" SQL Server edition. I'm attending a great SharePoint course for Daniel...(read more)

  • Avoiding connection timeouts on first connection to LocalDB edition of SQL Server Express

    - by Greg Low
    When you first make a connection to the new LocalDB edition of SQL Server Express, the system files, etc. that are required for a new version are spun up. (The system files such as the master database files, etc. end up in C:\Users\<username>\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\LocalDBApp1) That can take a while on a slower machine, so this means that the default connection timeout of 30 seconds (in most client libraries) could be exceeded. To avoid this hit on the...(read more)

  • JDK bug migration milestone: JIRA now the system of record

    - by darcy
    I'm pleased to announce the OpenJDK bug database migration project has reached a significant milestone: the JDK has switched from the legacy Sun "bugtraq" system to a new internal JIRA instance as the system of record for our bug tracking. This completes the initial phase of the previously described plan of getting OpenJDK onto an externally visible and writable bug tracker. The identities contained in the current system include recognized OpenJDK contributors. The bug migration effort to date has been sizable in multiple dimensions. There are around 140,000 distinct issues imported into the JDK project of the JIRA instance, nearly 165,000 if backport issues to track multiple-release information are included. Separately, the Code Tools OpenJDK project has its own JIRA project populated with several thousands existing bugs. Once the OpenJDK JIRA instance is externalized, approved OpenJDK projects will be able to request the creation of a JIRA project for issue tracking. There are many differences in the schema used to model bugs between the legacy bug system and the schema for the new JIRA projects. We've favored simplifications to the existing system where possible and, after much discussion, we've settled on five main states for the OpenJDK JIRA projects: New Open In progress Resolved Closed The Open and In-progress states can have a substate Understanding field set to track whether the issues has its "Cause Known" or "Fix understood". In the closed state, a Verification field can indicate whether a fix has been verified, unverified, or if the fix has failed. At the moment, there will be very little externally visible difference between JIRA for OpenJDK and the legacy system it replaces. One difference is that bug numbers for newly filed issues in the JIRA JDK project will be 8000000 and above. If you are working with JDK Hg repositories, update any local copies of jcheck to the latest version which recognizes this expanded bug range. (The bug numbers of existing issues have been preserved on the import into JIRA). Relatively soon, we plan for the pages published on bugs.sun.com to be generated from information in JIRA rather than in the legacy system. When this occurs, there will be some differences in the page display and the terminology used will be revised to reflect JIRA usage, such as referring to the "component/subcomponent" of an issue rather than its "category". The exact timing of this transition will be announced when it is known. We don't currently have a firm timeline for externalization of the JIRA system. Updates will be provided as they become available. However, that is unlikely to happen before JavaOne next week!

  • How can I deal with actor translations and other "noise" in third-party motion capture data?

    - by Charles
    I'm working on a game, and I've run into a problem with motion capture data. My team is using 3DS Max 2011 and trying to put free motion capture files on our models. The problem we're having is it has become extremely hard to find motion capture data that stays in place. We've found some great motion captures of things like walking and jumping but the actors themselves move within the data, so when we attach these animations to our models and bring them into XNA, the models walk forward even when they should technically be standing still (and then there's also the problem of them resetting at the end of the animation). How can we clean up, at runtime or asset-processing time, the animation in these motion capture files?

  • What is 'Ubuntu Unity' (for the Desktop)?

    - by Martin
    Ok, so there's the buzz of Canonical (wanting to) switch for new Ubuntu version from the GNOME default desktop to their own Unity shell. (I hope that's accurate.) It seems I can not totally fathom what Unity actually is. For looking at its homepage it currently is firmly targeted at netbooks and the somehow different usage model on these. Is it a classical desktop? -- Taskbar? Shortcuts? Is the difference between Ubuntu(GNOME)+Unity more/less pronounced than the difference between Ubuntu and Kubuntu? Will "my parents" be able to get the interface if they've been using the classical gnome desktop so far? Edit: I would not like to split this up into more specific questions, as What is Unity? is exactly what the people I set up Ubuntu boxes for will ask me if they hear that the newer Ubuntu version is using that instead of the Desktop -- and it might well happen someone phrases it like that :-) I will certainly not give them the link to the HP as the explanation there does not lay out if it is a desktop or something more or something less: (It does not for me - therefore I'm asking here.) Unity is designed for netbooks and related touch-based devices. It includes [...] that makes it fast and easy to access [...] while removing screen elements that are rarely used in mobile and netbook computing. (emphasis mine) -- the explanation there doesn't even mention the desktop-PC! Unity has a vertical task management panel on the left-hand side and a menu panel at the top of the screen. [...] This sounds like a re-themed normal desktop. Clicking on an icon will give the target application focus if it is already running or launch it if it is not already running. If you click the ... Aha. Sounds like Windows 7. ... icon of an application that already has focus, Unity will activate an Expose-style view of all the open windows associated with that application. No clue what that's supposed to be. So it would really be nice if someone could explain for non desktop-design-terms experts what Unity is.

  • determine collision angle on a rotating body

    - by jorb
    update: new diagram and updated description I have a contact listener set up to try and determine the side that a collision happened at relative to the a bodies rotation. One way to solve this is to find the value of the yellow angle between the red and blue vectors drawn above. The angle can be found by taking the arc cosine of the dot product of the two vectors (Evan pointed this out). One of my points of confusion is the difference in domain of the atan2 function html canvas coordinates and the Box2d rotation information. I know I have to account for this somehow... SS below questions: Does Box2D provide these angles more directly in the collision information? Am I even on the right track? If so, any hints? I have the following javascript so far: Ship.prototype.onCollide = function (other_ent,cx,cy) { var pos = this.body.GetPosition(); //collision position relative to body var d_cx = pos.x - cx; var d_cy = pos.y - cy; //length of initial vector var len = Math.sqrt(Math.pow(pos.x -cx,2) + Math.pow(pos.y-cy,2)); //body angle - can over rotate hence mod 2*Pi var ang = this.body.GetAngle() % (Math.PI * 2); //vector representing body's angle - same magnitude as the first var b_vx = len * Math.cos(ang); var b_vy = len * Math.sin(ang); //dot product of the two vectors var dot_prod = d_cx * b_vx + d_cy * b_vy; //new calculation of difference in angle - NOT WORKING! var d_ang = Math.acos(dot_prod); var side; if (Math.abs(d_ang) < Math.PI/2 ) side = "front"; else side = "back"; console.log("length",len); console.log("pos:",pos.x,pos.y); console.log("offs:",d_cx,d_cy); console.log("body vec",b_vx,b_vy); console.log("body angle:",ang); console.log("dot product",dot_prod); console.log("result:",d_ang); console.log("side",side); console.log("------------------------"); }
