• Changing mouse behaviour in EOG

  - by Wauzl

  When I open a photo in eog I can easily zoom with the mouse mouse wheel. This is kind of nice but since I have a touchpad with two-fingered scrolling and horizontal scrolling I'd rather scroll in the image and zoom by using Ctrl+Mouse Wheel? I basically want the same behaviour as in evince: Horizontal Scroll and Normal Scroll navigate within the image and Ctrl + Mouse Wheel zooms in and out. Is this possible somehow? [EDIT] I just figured out that what I want is already implemented: I can pan the image by using Ctrl + Mouse Wheel. This is fine as it is the behaviour I want only with the Ctrl inverted. But I cannot pan to the left. Up, down and right work fine. What's the problem?

• It's noisy in ubuntu,why?

  - by Jinx

  I just installed an ubuntu on my pc(Dell Inspiration I560SR-358, with CPU E5700 3GHz, 4G memory, and NVIDIA GeForce G310). The pc becomes noisy before that it's quiet with a windows 7 on it. How come? How to set it to be quiet again in unbuntu 10.04. One of the two cpu usage is always 100%. I think that is the reason. //re-edit Everything gets ok after I restart the computer.But the fan is still running which makes it noisy, if i switch to windows 7, it becomes quiet again.

• How can I make the camera return to the beginning of the terrain when it reaches the end?

  - by wbaccari

  How can I make the camera return to the beginning of the terrain when it reaches the end? I tried using the ICameraSceneNode*-setPosition(). if (camera->getPosition().X>1200.f) camera->setPosition(vector3df(1.f,1550.f,camera->getPosition().Z)); if (camera->getPosition().X<0.f) camera->setPosition(vector3df(1199.f,1550.f,camera->getPosition().Z)); if (camera->getPosition().Z>1200.f) camera->setPosition(vector3df(camera->getPosition().X,1550.f,1.f)); if (camera->getPosition().Z<0.f) camera->setPosition(vector3df(camera->getPosition().X,1550.f,1199.f)); It seems to work fine with a flat terrain (one shade of grey in heightmap) but it starts to produce a strange behavior as soon as i try to add some hills. Edit: The setPosition() call seems to perform a translation of the camera toward the new position, therefore the camera stops at the first obstacle it encounters on its way.

• Which simple Java JPA ORM tool to use ?

  - by Guillaume

  What Java ORM library implementing JPA that match following criteria would you recommend and why ? free & open source alive (at least bug fixes and a mailing list) with good documentation simple (simpler than hibernate) I need to select a simple ORM tool that can be set up in minutes, without too much configuration and easy to understand, for setting simple CRUD DAOs. A query builder will be an interesting plus. Later I can have to move to Hibernate, that's why being JPA compliant is a must. I have found some candidates on the web, but not so much feedback, so I will gladly take your advices on the topic. ----- EDIT --------- I have been successfully testing ebean/avaje with a small test cases. Any one has a feedback on using these tools in production ?

• how to create texture for modelmesh?

  - by Berend

  Is there a possibiltiy to create a texture from a meshpart in xna. By getting a flat version of the mesh. So I can create a texture for it and edit that texture(via rendertarget)? I need to get the texture(wich is not yet a texture) so I can put another texture on it. I can create a texture and put it on a certain mesh. But I just cant figure out how I can create a texture with the right size. I also already found out i can use text2dproj in hlsl. But when i do this i get a gray stripe in the look. Is there a better solution?

• Ubuntu installer doesn't see internal hard drive on DELL Vostro 3360

  - by valk

  I just received a new DELL Vostro 3360, it has Windows 7 preinstalled. When it comes to the partition window I can't see the hard drive there. I see only /dev/sda or /dev/sdb (either one and in both cases it's a usb drive from which I'm installing). I tried every imaginable BIOS configuration. Tried to change the SATA mode to ATA, DHCI and more. EDIT: I tried to install with standard Ubuntu 12.04 32 bit, and 11.10 64 bit official versions. No luck. I'll appreciate any suggestion.

• Transformation matrix that maps a window

  - by gbhall

  I'm currently learning OpenGL at uni, and they give us questions to help us learn (these are not worth anything), however I'm stuck on this one question and would have to travel over an hour and a half to uni for an answer. How do I do this question? Please include as many steps as you can, I want to be able to follow exactly how to do this. Find the transformation that maps a window whose lower left corner is at (1,1) and upper right corner is at (3,5) onto: The entire device screen whose dimension is (600, 500) A viewport that has lower left corner at (100,100) and upper right corner at (400,400) Edit: Damn sorry I should have added I am meant to find the matrix, so no code.

• Time jumping forward on NTP failure

  - by Dan

  I have been having some weird problems with NTP for a while. If I use ntpdate to set the time then it sets fine. ntpd then invariably fails to find a server (I have loads configured) and decides to set the clock forward about 5 hours. It's a Xen server with dom0 set to a different timezone so I'm not sure if that is interfering with it. How can I make sure I ignore the dom0 time and have ntpd not change the time if it fails to reach a time server? EDIT: I now do not think it is ntpd giving me problems, I turned ntpd off and it jumped forward seemingly randomly.

• Command 'setenv' not found upon installation of Crystal09 program

  - by Geninho

  Command 'setenv' not found I use ubuntu 11.04 I tried to install the program "Crystal09" and in the tutorial asks you to copy the file cry2k9.cshrc to the home directory. I copied the file, but when I do the command "source cry2k9.cshrc" (which is the installation tutorial) the following error appears (This error message is in Portuguese-br): (Translated :edit) Command 'setenv' not found, did you mean: Command 'netenv' package 'netenv' (universe) setenv: command not found Command 'setenv' not found, did you mean: Command 'netenv' package 'netenv' (universe) setenv: command not found CRY2K9_SCRDIR - scratch directory (integrals and temp files): CRY2K9_EXEDIR - directory with crystal executables: CRY2K9_UTILS - running scripts and misc: /runcry09, runprop09 CRY2K6_GRA - graphical scripts: /maps06, doss06, band06 CRY2K9_TEST - directory with test cases:

• /etc/X11/xorg.conf doesn't exist?

  - by BBetances

  I'm trying to get my video card properly setup to handle 3D acceleration. After searching a bit, I've come across a few howtos that tell me I need to edit my xorg.conf file. That file doesn't exist. X.org is installed by default, I'm sure, and I figured this video card would be widely supported. 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) Any ideas on how I can get this to work properly and play Starcraft II? Or any game for that matter? No resolution problems or anything, just no 3D rendering.

• Panel Background color, Transparency and background image don't work with Ambiance theme

  - by Ash G

  As the title suggests. Selecting a background image, color or using the transparency sitting doesn't work with the Ambiance theme. Sections of the panel will take the new settings, but many of the applets including the clock, Indicator Applet Session, Indicator Applet, Rhythmbox icon, Tomboy Icon, Separators and various others retain the Ambiance theme background. This carries over through restart. Also you cannot resize the panel in Ambiance above 24 pixels as the background image doesn't scale. Am I doing something wrong, is it a bug or is it meant to be like that? I really like Ambiance, but am having a hard time using it because of these issues Edit: It seems these issues carry over to Radiance and New Wave as well

• Tiled/TMX C++ Library/Parser

  - by Ben

  Where can I find an easy to use and up to date C++ parser/library for the .tmx map format (used by the Tiled Map Editor) ? EDIT: David's comment, 'Unless you want to build your game around the format of the parser..', got me thinking... So I have downloaded pugixml, which is an easy to use xml-parser with very straightforward documentation. Together with the spec for the TMX Map Format, I think I'll give it a try myself. I'll probably compare with Cocos2d-x's CCTMXTiledMap at some point.

• How is this number calculated?

  - by Hamid

  I have numbers; A == 0x20000000 B == 18 C == (B/10) D == 0x20000004 == (A + C) A and D are in hex, but I'm not sure what the assumed numeric bases of the others are (although I'd assume base 10 since they don't explicitly state a base. It may or may not be relevant but I'm dealing with memory addresses, A and D are pointers. The part I'm failing to understand is how 18/10 gives me 0x4. Edit: Code for clarity: *address1 (pointer is to address: 0x20000000) printf("Test1: %p\n", address1); printf("Test2: %p\n", address1+(18/10)); printf("Test3: %p\n", address1+(21/10)); Output: Test1: 0x20000000 Test2: 0x20000004 Test3: 0x20000008

• How to handle bugs that I think I fixed, but I'm not entirely sure

  - by vsz

  There are some types of bugs which are very hard to reproduce, happen very rarely and seemingly by random. It can happen, that I find a possible cause, fix it, test the program, and can't reproduce the bug. However, as it was impossible to reliably reproduce the bug and it happened so rarely, how can I indicate this in a bugtracker? What is the common way of doing it? If I set the status to fixed, and the solution to fixed, it would mean something completely fixed, wouldn't it? Is it common practice to set the status to fixed and the solution to open, to indicate to the testers, that "it's probably fixed, but needs more attention to make sure" ? Edit: most (if not all) bugtrackers have two properties for the status of a bug, maybe the names are not the same. By status I mean new, assigned, fixed, closed, etc., and by solution I mean open (new), fixed, unsolvable, not reproducible, duplicate, not a bug, etc.

• Achieving more fluent movement

  - by Robin92

  I'm working on my first OpenGL 2D game and I've just locked the framerate of my game. However, the way objects move is far from satisfying: they tend to lag, which is shown in this video. I've thought how more fluent animation can be achieved and started getting segmentation faults due to accessing the same object by two different threads. I've tried the following threads' setting: Drawing, creating new objects Moving player, moving objects, deleting objects Currently my application uses this setting: Drawing, creating new objects, moving objects, deleting object Moving player Any ideas would be appreciated. EDIT: I've tried increasing the FPS limit but lags are noticeable even at 200 fps.

• Ubuntu Server 12.10 No GUI Headless Boot and/or Reboot

  - by Ubuntu User

  I have a headless server running the latest Ubuntu Server 12.10. It does not have any GUI at all. I am having the same issue that others are having which is that when you boot or reboot without a monitor (headless) the computer does not boot. The solution presented to others was to edit their xorg.conf file. But since I do not want a GUI installed (and therefore chose not to install a GUI after installing Ubuntu 12.10) I do not have a xorg.conf file in the /etc/X11/ directory. Ubuntu is a widely used distro of Linux, especially for server applications, I absolutely love it. Therefore, there has to be someone who solved this already?

• Procedural Mesh: UV mapping

  - by Esa

  I made a procedural mesh and now I want to apply a texture to it. The problem is, I cannot get it to stick the way I want it to. The idea is to have the texture painted only once over the whole mesh, so that there is no repeating. How should I map the UV to make that happen? My mesh is a simple plane consisting of 56 triangles. I'd add pictures to clear things up but I cannot since my reputation is below 10 points. Any help is appreciated. EDIT(Kind people gave me up votes, thank you): Meet my mesh: And when textured(tried to repeat the texture): And my texture:

• Stuck while Booting Text Mode in Ubuntu 12.04?

  - by sameetandpotatoes

  I edited the /etc/default/grub file and changed: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” to GRUB_CMDLINE_LINUX_DEFAULT=”text” This does make Ubuntu boot up into text mode; however, it gets stuck while booting up and it does not show me the login text. Instead it says something like this: Begin running /scripts/init-bottom USB hub found ...More irrelevant things... *Stopping LightDM Display Manager I can press Ctrl + Alt + F2 and see the login and boot up like normal, but is there any reason for this? How can I change it so it does not get get stuck? Edit: After 5 minutes, a new line came up: 557.1206341 ieee80211 phy0: channel change: 5540 -> 5560 failed (3).

• Remove bottom panel from a remastered LiveCD

  How can I remove or autohide to 0 the bottom Gnome panel from a remastered liveCD and autostart AWN (or any dock for that matter...) to replace it? , just as moonOS 4 (the distro that gave me the idea to try to do this) Using this command to enable the auto hide gconftool-2 -t bool -s /apps/panel/default_setup/toplevels/bottom_panel/auto_hide "true" i Figured out how to Autostart AWN,however that involves removing BOTH panels, so im not quite there yet Using UCK gconf-editor to manually edit the option to auto hide the bottom panel doesn't work, when testing the livecd BOTH panels are still there, even though i use the command and then run gconf-editor to check that the option is eneabled, which it is, however, once the livecd starts the autohide feature is disabled

• Align tetrahedrons

  - by thedeadlybutter

  I'm currently generating tetrahedron meshes in Unity When a player clicks the side of a mesh, a new one spawns aligned with it, like this. I'm not sure how nor can I find any information on implementing a tetra hedron grid. I tried playing around with the vertices until I realized I need to adjust position & rotation. Any ideas? EDIT: To be clear, the second image was manually placed objects in the Unity Editor. I'm looking to make an algorithm that places the meshes correctly.

• Windows 8 SDK and Orca

  - by John Paul Cook

  The Windows 8 SDK has a new version of Orca for those of us who edit msi files. The download is for a small executable, sdksetup.exe which causes the following dialog box to appear.

In this example, the files are downloaded to D:\Media\Windows8\SDK Figure 1. Downloading the Windows 8 SDK to D:\Media\Windows8\SDK instead of installing it. Click the D ownload...(read more)

• How To Get Browser To Open From Same Folder?

  - by Bad Learner

  I don't know how to make the title any more clear. Let me give an example - When I want to add an image to an article on my blog, I click "Browse" button in the image uploader, and then upload the image to the blog. The problem is, when I want to upload another image to my blog, I want the browser to look into the same directory; but it's always takes me to the "Recently Used" directory. Is there a way to change this? I hope I have made myself clear enough. EDIT: I only use Chrome, so I am referring to it.
