• How to control in the vertex shader where pixel ends up in the renderTarget?

  - by cubrman

  What if I have an arbitrary renderTarget, that is smaller than the screen (say it is 1x1 pixel) and I want to make sure in the VertexShaderFunction that all my pixels end up exactly in that 1 pixel region? No matter what I do, they all seem to get culled at some point, though GraphicDevise.Clear() works OK. Where is the top left corner of the renderTarget Vertex-shader-vise? I tried output.Position = (0,0,0,0)/(0,0,0,1)/(1,1,1,1)/(-0.5,0.5,0,1) NOTHING works! Fullscreen quad is not an option 'cause I actually need to process geometry in the shaders to get the results I need.

• Brainworkshop won't go fullscreen

  - by user1777025

  I am unable to run brainworkshop in fullscreen mode. After correctly changing the config.ini file to launch the script in fullscreen mode all I get is a window of the same size as before but with no frame or title bar, aligned to the top right (below the menu bar and to the right of the edge of the screen). I tried posting a screenshot but as I'm a new user I wasn't allowed to... I tried looking around in the pyglet files to see if I could find anything that might be causing this but it's all beyond me. Any suggestions? Right after posting this I relaunched the script and now the same borderless, resizeable window is launched aligned to the bottom right hand corner of the screen... I'm running ubuntu 12.04 and brainworkshop 4.8.4.

• SQL Social

  - by SteveP

  Wanted to thanks Simon for putting together a great event last night.  It was a real pleasure to be in the company of some of the greats(Itzik, Greg, Davide, Bill and not forgetting Mr Sabin) in the SQL server space.  The venue was superb and the knowledge of the panel covered pretty much every corner of the SQL Server platform.  I'm very much looking forward to seeing how the social evenings progress.  It's going to be hard to follow this one.

• I can't open Ubuntu Software Center

  - by user165700

  I downloaded google chrome that was made for my computer from https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb. For some reason after I installed I can't open. Also in the corner where the time and other things are there's this red circle with a white dash in the middle of it. It says "An error occured, please run package manager from the right click menu or apt-get in a terminal to see what is wrong. The error message was: 'Unknown Error:''(E:The package google-chrome-stable needs to be reinstalled,but I can't find an archive for it.)' This usually means that your installed packages have unmet dependencies.

• Steady zoom on center in LWJGL (Modelview)

  - by l5p4ngl312

  I am having a problem in LWJGL with zooming in and out. I am using glScaled(zoom, zoom, 1) before glTranslated. There are 2 problems: 1. The rate of zoom speeds up a lot when zooming out (lower zoom value). 2. It zooms in on the bottom left corner of the screen rather than the center. Eventually, I would like to have the zoom focused on the mouse position. I have tried to fix these problems by make it glScaled(zoom^12, zoom^12, 1) so that the greater the zoom value, the faster it will zoom in order to balance out the faster zoom at lower zoom values. To compensate for the zoom focused on the bottom left, I have tried to subtract (zoom+1)^10 + 2^10 from the X and Y of each sprite. This results in a curved zoom path, first to the left and then to the right. It is a 2D game.

• Remove/add indicator icons

  - by user209835

  I'm trying out Ubuntu 13.10. I would like to remove some of the default indicator icons in the upper right corner. Is there an easy way to do it? And then I would like to add some other icons (guake, pidgin, shutter, dropbox, kupfer etc.). I have already got the dropbox icon but it's in grey. I would like the default blue icon with the green marker. But if I change theme in ubuntu-tweak or gnome-tweak then the nice shutdown-icon disappears. In linux mint this just works :-).

• Beginner's guide to writing comments?

  - by Cameron

  Is there a definitive guide to writing code comments, aimed at budding developers? Ideally, it would cover when comments should (and should not) be used, and what comments should contain. This answer: Do not comment WHAT you are doing, but WHY you are doing it. The WHAT is taken care of by clean, readable and simple code with proper choice of variable names to support it. Comments show a higher level structure to the code that can't be (or is hard to) show by the code itself. comes close, but it's a little concise for inexperienced programmers (an expansion on that with several examples and corner cases would be excellent, I think).

• How to flip a BC6/BC7 texture?

  - by postgoodism

  I have some code to load DDS image files into OpenGL textures, and I'd like to extend it to support the BC6 and BC7 compressed formats introduced in D3D11. Since DirectX and OpenGL disagree about whether a texture's origin is in the upper-left or lower-left corner, my DDS loader flips each image's pixels along the Y axis before passing the pixels to OpenGL. Flipping compressed textures presents an additional wrinkle: in addition to flipping each row of 4x4-pixel blocks, you also need to flip the pixels within each block. I found code here to flip BC1/BC2/BC3 blocks, and from the block diagrams on MSDN it was easy to adapt the BC3-flipping code to handle BC4 and BC5. The BC6 and BC7 formats look significantly more intimidating, though. Is there a similar bit-twiddling trick to flip these formats, or would I have to fully decompress and recompress each block?

• I can't get Ubuntu installation to start

  - by tyler

  I have a computer with the following configuration: AZUS Sabertooth Motherboard Intel I5 2500 CPU Windows 7 installed I'm trying to install linux. I first attempted to install pin guy. I burned the ISO, booted from it, got the initial menu; attempting to either run the live version from DVD, or install to system. However the process stops at a blank screen with the blinking cursor in left corner. So I downloaded Ubuntu and got the same results. Then I tried wubi and ended up in the same position. EDIT: UEFI might be part of the problem? Based on the link below I have determined that the process will be too time consuming and or risky so I'm giving up. https://help.ubuntu.com/community/UEFIBooting

• How do I import Amazon MP3s with Banshee and the new Amazon Cloud Player?

  - by adempewolff

  Banshee's Amazon MP3 Import extension until recently allowed seamless importing of songs purchased from Amazon MP3. It did this by a)opening .amz files and using them to connect to and download the purchased files from Amazon's servers, and b) using hooks in Banshee's built-in browser to automatically recognize and open the .amz files when clicked on in the browser. However, recently this functionality stopped working. Banshee will display Contacting Server in the lower left hand corner for a little while and then stop. Furthermore opening the Amazon Cloud Player in the Banshee browser or any other browser on a Linux system to manually download the .amz file now results in the message: On Linux systems, Cloud Player only supports downloading songs one at a time. To download your music, deselect all checkboxes, select the checkbox for the song you want to download, then click the "Download" button. How can I get around this and import my purchased music into Banshee as I used to?

• How can I force X to start in a computer without a monitor?

  - by Javier Rivera

  I have I computer that have no monitor attached. When I boot it X fails to start because there is no monitor detected. If I boot it with a monitor attached and after X is started I remove the monitor everything works fine. Details and Background: This computer is a kind of hardware consolidation server. It's only purpose is to run two Virtual Box VM's that run Windows XP and some important but seldom used (once or twice a month) programs. For a couple of time it has been lying in a corner with an old monitor attached to it and working great. But space in the office was getting scarce and I moved the computer to the server room. There is no monitor attached to it there (no space), and sometimes the computer is rebooted. When it boots without monitor X is not started, the vms don't start and I get called to solve the problem.

• Resetting network adapter?

  - by Quixo

  I'm running Ubuntu 12.04. I get a strong wireless signal throughout my house, and the wireless symbol in the upper-right-hand corner shows that it's connected. The problem is, occasionally I am unable to access the internet (still having a strong symbol). This happened with Windows 7, too, but running the network troubleshooter fixed it each time. It claimed to be "resetting the network adapter". So, what I need to know is: How do I replicate that process on Ubuntu? Thanks for your help!

• Beginner Guide to User Styles for Firefox

  - by Asian Angel

  While the default styles for most websites are nice there may be times when you would love to tweak how things look. See how easy it can be to change how websites look with the Stylish Extension for Firefox. Note: Scripts from Userstyles.org can also be added to Greasemonkey if you have it installed. Getting Started After installing the extension you will be presented with a first run page. You may want to keep it open so that you can browse directly to the Userstyles.org website using the link in the upper left corner. In the lower right corner you will have a new Status Bar Icon. If you have used Greasemonkey before this icon works a little differently. It will be faded out due to no user style scripts being active at the moment. You can use either a left or right click to access the Context Menu. The user style script management section is also added into your Add-ons Management Window instead of being separate. When you reach the user style scripts homepage you can choose to either learn more about the extension & scripts or… Start hunting for lots of user style script goodness. There will be three convenient categories to get you jump-started if you wish. You could also conduct a search if you have something specific in mind. Here is some information directly from the website provided for your benefit. Notice the reference to using these scripts with Greasemonkey… This section shows you how the scripts have been categorized and can give you a better idea of how to search for something more specific. Finding & Installing Scripts For our example we decided to look at the Updated Styles Section”first. Based on the page number listing at the bottom there are a lot of scripts available to look through. Time to refine our search a little bit… Using the drop-down menu we selected site styles and entered Yahoo in the search blank. Needless to say 5 pages was a lot easier to look through than 828. We decided to install the Yahoo! Result Number Script. When you do find a script (or scripts) that you like simply click on the Install with Stylish Button. A small window will pop up giving you the opportunity to preview, proceed with the installation, edit the code, or cancel the process. Note: In our example the Preview Function did not work but it may be something particular to the script or our browser’s settings. If you decide to do some quick editing the window shown above will switch over to this one. To return to the previous window and install the user style script click on the Switch to Install Button. After installing the user style the green section in the script’s webpage will actually change to this message… Opening up the Add-ons Manager Window shows our new script ready to go. The script worked perfectly when we conducted a search at Yahoo…the Status Bar Icon also changed from faded out to full color (another indicator that everything is running nicely). Conclusion If you prefer a custom look for your favorite websites then you can have a lot of fun experimenting with different user style scripts.

• Running 32-bit Firefox with sun-jre in 64-bit Ubuntu

  - by rojanu

  I am trying to run juniper networks connect program to vpn into work and it only works on 32bit sun jre. All the things I have found with google failed so far. I can't use any scripts, like madscientists, as part of the authentication I need to provide some random characters from a grid. So to isolate this 32bit app install to a corner, I downloaded firefox and jre and unpack them to /opt. I run firefox with sudo as Juniper asks for root password. Here is Firefox plugins folder /ot/firefox32/plugins# ls -la total 8 drwxr-xr-x 2 root root 4096 Mar 11 00:57 . drwxr-xr-x 11 root root 4096 Mar 10 23:48 .. lrwxrwxrwx 1 root root 49 Mar 11 00:57 libnpjp2.so -> /opt/java/32/jdk1.6.0_31/jre/lib/i386/libnpjp2.so Firefox lists sun jre but when check it with "http://java.com/en/download/installed.jsp" it either can't detect java or Firefox freezes Any Ideas? Thanks

• What happens if you're unable to solve a problem?

  - by gablin

  I'm a year away from graduating from university, and I'm really looking forward to solving practical problems. Especially non-trivial ones which require a bit of research and a lot of thinking. But at the same time, that is also my greatest fear - being faced with a problem that I'm unable to solve, no matter how hard I try. And with pressure to deliver code on impending deadlines just around the corner, it does look a bit scary when viewing it from the safe playgrounds on uni (where the worst thing that can happen is that you have to redo a course or exam). So for those who have been in industry for any longer length of time, what would happen if you were told to solve a problem that you couldn't? Has it happened, and if so, what did happen? Did they just drop it and said "Oh well, guess we can make do with something else"? Were there consequences? Were you reprimanded, or even fired?

• Determine percentage of screen covered by an object without using frustum culling

  - by Meltac

  On the CPU-side of an 3D first-person / ego perspective game I need to check whether what the players currently sees on screen is the inside of a box object defined by world space coordinates (the player might be outside of that box but on screen sees only/mostly the inside of the box, or vice-versa, looks from within the box to the outside). The "casual" way of performing such a check would incorporate frustum culling but such an approach would be hard to achieve with my given set of engine parameters which I'd like to avoid if there is a simpler way. What I actually have at the point where I would like to do the check (high-level script on CPU, not GPU side): Camera world position Camera direction Camera FOV Two Box corner world coordinates (left-bottom-front, right-top-back) What I do not have right away: View frustrum definition (near/far plane or say 6 planes defining frustum) Any specific pixel information (uv, view space position, depth or the like) What I would like to calculate: Percentage of screen "covered" by box. Any hints on how to perform such calculation?

• Force gdm login screen to the primary monitor

  - by Kirill

  I have two monitors attached to my video card. Primary monitor has a resolution equal to 1280x1024 and the second has 1920x1200. My gdm login screen always appears on the second monitor even if it is switched off. My question is how to force gdm to show the login screen always on the primary monitor with resolution 1280x1024? I use Nvidia GT9500 videcard in Twinview mode. I can't use Xinerama because vpdau doesn't work correclty in this mode. What I have found is that mouse pointer always appears in the center of union of the screens and center is always on the monitor with higher resolution. Login screen always shows where mouse cursor is. Now my primary monitor has a resolution equal to 1920x1080. The problem still persists, mouse cursor always appears in the right-bottom corner of the second monitor.

• Setting Anchor Point

  - by Siddharth

  I want to set anchor point for the sprite like cocos2d has done for their implementation. I do not found any thing like that in andengine so please provide guidance on that. I want to move the sprite on touch so I use following code but that does not work for me. super.setPosition(pX - this.getWidthScaled() / 2, pY - this.getHeightScaled() / 2); Because I touch on the corner of the image but automatically it comes at center of the image because of above code. I want to remain the touch at desire position and drag it. For me the anchor point became useful. But I don't found anything in andengine.

• Ubuntuone fails to sync with 'File Sync starting...' displayed

  - by a different ben

  I am on 12.04 using ubuntuone-client 3.0.1-0ubuntu1.0.1. I actually have two machines that I sync with, having the same Ubuntu version and ubuntuone-client version. One is fine, the other is not. File sync has frozen within a user-defined folder under my home folder. The graphical client reports in the top-right corner: 'File Sync starting...', but this doesn't change. I have two files with changes that show a syncing overlay in Nautilus. They are both very small text files. Here are some details: harb@joan:~$ u1sdtool --status State: READY connection: With User Not Network description: ready to connect is_connected: False is_error: False is_online: False queues: WORKING harb@joan:~$ u1sdtool --current-transfers Current uploads: 0 Current downloads: 0 The status seems to suggest that I am not connected to a network, however I am connected to a network - in fact I am accessing this machine via NX. Is it not working because I am connected via NX? Happy to provide other info, just not sure what would be useful.

• Ubuntu server 13 hangs on boot

  - by Slava Fomin II

  I formatted my WD30EFRX 3TB SATA HDD as GPT with the following layout: 200 MB FAT32 (BOOTABLE) 50GB EXT4 (Mount point: /) 4 GB SWAP SPACE ~2.9 TB EXT4 (with no mount point) Then i created a Flash USB using Rufus 1.3.3 and the following ISO-image: ubuntu-13.04-server-amd64.iso. I used following configuration to create the USB: GPT partition scheme for UEFI computer FAT32 (16KB) I successfully booted from this USB on my Intel D510MO motherboard in UEFI mode (there were a black and white boot loader menu instead of a colorful GUI) and installed the OS. During the boot loader installation i saw it was grub-efi-amd64 as it must be. After installation i removed the flash drive and tried to boot the system, but just after a BIOS POST it hangs (there is a white blinking cursor at the left top corner of the black screen) and nothing happens. UEFI Mode is enabled in the BIOS configuration and i've updated the BIOS to the latest firmware. What went wrong, how i can confirm that system was installed properly? How can i boot the OS?

• Gmail Rolls Out New Compose Features

  - by Jason Fitzpatrick

  Gmail has several new features that make it even easier to compose email messages including pop-over compositions windows (similar to the Google Chat window), contact profile pictures in the address box, and drag and drop address switching. If you’ve ever had to open two separate windows in order to continually tab back and forth so you could reference one email while composing another, you’ll certainly appreciate the new pop-over compose window that allows you to work within Gmail while keeping a small email composition window open in the corner–as seen in the screenshot above. In addition to that major change, Gmail has also introduced contact photos in the address suggestion window (making it easier than ever to make sure you’re selecting the right recipient) and the ability to drag and drop addresses between the To:, CC:, and BCC: address slots.
