  • Why don't we have an "unofficial" software center with all the PPAs?

    - by balki
    Many questions are answered simply with add this repository and install. I understand that Ubuntu developers cannot quickly verify all packages and make them available in official repositories. But is there an unofficial main repository or software center where developers can register their PPAs? Adding individual repositories is a pain and the update also takes longer as it has to check all the PPAs. Like we have alternative markets for android, it would be great if there are any popular alternative software sources that we can reasonably trust.

  • How to handle a Tile Map Scrolling [duplicate]

    - by DGomez
    This question already has an answer here: Implementing a camera / viewport to a 2D game 1 answer i'm making a video game, and i'm having, i think, a concept problem. The game will be a platformer which will use tile maps, so to start i will create a mask matrix indicating the tiles to be loaded, and etc..., so my problem is, how to handle the scrolling? should i create a giant mask matrix indicating in each position of the whole level what is supposed to be loaded, and according to the position of the player, change the section to be drawed?? Is this a correct approach to this situation??

  • What You Said: Staying Productive While Working from home

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your telecommuting/work-from-home productivity tips. Now we’re back with a tips and tricks roundup; read on to see how your fellow readers stay focused at home. By far and away the most common technique deployed as carefully isolating work from home life. Carol writes: I love working from home and have done so for 6 years now. I have a routine just as if I was going to an office, except my commute is 12 steps. I get ready for work, grab my purse and smart phone and go to up the steps to my office. I maintain a separate phone line and voice mail for work that I cannot answer from anywhere but my work desk. I use call forwarding when I travel so only my office phone number is published. I have VOIP phone service so I can forward calls from the internet if I forget, or need to change where the phone is forwarded. I do have a wired and wireless head set so I can go get a cold drink if on one of those long boring conference calls. I plan my ‘get off from work’ time and try to stick to it, as with any job some days I am late getting off, but it all works out. I make sure my office is for work only, any other computer play time is in a different part of the house on different computer. My office has laptop, dock, couple of monitors, multipurpose printer, fax, scanner, file cabinets – just like the office at a company. I just also happen to have a couple of golden retrievers that come to work with me and usually lay quietly until 5, and yes they know it is 5pm sometimes before I do. For me, one of the biggest concerns when working from home is not being unproductive, but the danger of never stopping work. You could keep going and going because let’s face it – the company will let you do it, so I set myself up to prevent that and maintain a separateness.

  • How can I change resolution of "my video" in Skype?

    - by koushik
    I have a logitech Quickcam Pro 9000 connected to my ubuntu desktop and it works fine with Skype. However, Skype inputs and sends my video at the native (for the webcam I think) resolution of 1600 x 1200. I can confirm that the camera supports a wide variety of resolutions starting from 160 x 120 upto 1600 x 1200 (including e.g., 320 x 240, 352 x 288) using cheese. I can select these resolutions and see the output is appropriately scaled. Also, I don't see any improvements in smoothness of motion in the captured video so I suspect the original 1600 x 1200 is scaled down in the path somewhere. Is it possible to somehow to enable this scaling capability towards Skype?

  • Isometric tile range aquisition

    - by Steve
    I'm putting together an isometric engine and need to cull the tiles that aren't in the camera's current view. My tile coordinates go from left to right on the X and top to bottom on the Y with (0,0) being the top left corner. If I have access to say the top left, top right, bot left and bot right corner coordinates, is there a formula or something I could use to determine which tiles fall in range? I've linked a picture of the layout of the tiles for reference. If there isn't one, or there's a better way to determine which tiles are on screen and which to cull, I'm all ears and am grateful for any ideas. I've got a few other methods I may be able to try such as checking the position of the tile against a rectangle. I pretty much just need something quick. Thanks for giving this a read =)

  • How can I get my wireless webcam to work?

    - by hellocatfood
    I recently bought this wireless webcam. I'm having trouble getting it to work on Ubuntu 11.04. I ran lsusb and got the folowing information about the device Bus 006 Device 003: ID 0416:a91a Winbond Electronics Corp. I did a Google serach for teh device ID and this website informs me that it matches the LogiLink Wireless Webcam (so Maplin probably just rebranded this!). What this website states is that this device should work, which it doesn't. The problem I'm facing is that I don't get any actual video being streamed or shown. The built in microphone works and, when running Cheese, when I press the camera button on the webcam itself the software recognises that the button is pressed. On that note, when running cheese from the terminal with this webcam attached I get the following error libv4l2: error getting pixformat: Invalid argument libv4l2: error setting pixformat: Input/output error Any help is appreciated

  • C# XNA render an entire frame to a texture2d

    - by redcodefinal
    I asked a question here: C# XNA Make rendered screen a texture2d But, I ended up not getting the exact result I was looking for since I didn't ask the question right. In a game I am writing, I render an extremely large city out of objects, this can cause lag when moving the camera to view things that are off screen. I need a way to render then ENTIRE city, even the stuff that is off screen, and make it into a Texture2D. The answer I chose for the last one didn't work entirely right because it only gets what is on screen, not what is off.

  • Somes importants shorcuts of Blender does not work on Ubuntu

    - by Linko
    In Ubuntu (and Mint) some important shortcuts for Blender does not work. Alt + right click to select an edge loop (heavily used on all 3D softwares) doesn't work, a useless menu of Ubuntu pop up to ask if the application must be closed or minimize. Ctrl + Alt + 0 to define the current view as the view of the camera minimize the application. This shortcut of Ubuntu is useless, it's faster to click on the minimize icon. Ctrl + number to apply a subdivision surface level do nothing on Blender, it's one of the most used shortcut of Blender. For the moment I stay on Windows 7 just to use these 3 shortcuts.

  • What are the semantics of glRotate and glTranslate's parameters?

    - by Zarkopafilis
    I have been trying to play with OpenGL after watching some tutorials and I don't understand how the glTranslatef and glRotatef functions work. I believe a simple picture would help me. I understand that glTranslatef changes the position of the "camera" (but does it change the position in wich the shapes are getting drawn)? However, I don't understand the rotation concept at all. If I do glRotatef(1,0,0,1) it makes my quad spin around. If I just do glRotatef(1,0,0,0) it makes the quad smaller (further away) but if I try to rotate around the X or Y axis, I get a black screen. I don't understand the angle either. Help would be appreciated.

  • XNA Octree with batching

    - by Alex
    I'm integrating batching in my engine. However I'm using an octree which is auto generated around my scene. Now batching renders a hole group at ones while an octree sorts out which objects that should be rendered within the camera frustum, therefore dividing the group. Batching and octree doesn't go along very well, right? Problem: The way I see it I have two options, either create batch groups based on objects who are close to one another within the octree or I can rebuild the batching matrixbuffer for the instances visible each frame. Which approach should I go with or does there exist another solution?

  • Do I lose/gain performance for discarding pixels even if I don't use depth testing?

    - by Gajoo
    When I first searched for discard instruction, I've found experts saying using discard will result in performance drain. They said discarding pixels will break GPU's ability to use zBuffer properly because GPU have to first run Fragment shader for both objects to check if the one nearer to camera is discarded or not. For a 2D game I'm currently working on, I've disabled both depth-test and depth-write. I'm drawing all objects sorted by their depth and that's all, no need for GPU to do fancy things. now I'm wondering is it still bad if I discard pixels in my fragment shader?
