  • Why do people like widescreen when it is, de facto, less space?

    - by Kerry
    I find that many of my friends/non-programmers or designers like widescreens. It makes very little sense to me as you in fact have less space than a 4:3 (do the math). The closer to a perfect square the more space you actually have on your screen. I got a 21" 16:9 and two 19" 4:3 The 21" is nearly the same height, but I think its a tenth of an inch shorter if I'm correct. I forget the calculation but it is nearly the same actual space. I can understand if you're using your computer for constant movie-watching but I think that's more of people's "ideal" than a reality. Thoughts?

  • How do I make the PC Zune download a movie, not stream it?

    - by bharal
    As the title suggests - I have bought a TV show series season on PC Zune. My girlfriend watched the show, and now I'd like to be able to watch the show too. The catch - I'm going to go overseas on a trip soon, and I'd like to be able to watch the show from outside the US. Given that Zune won't let me stream things overseas (past experience, anyway), I would like to download the show to my computer and watch it that way. The problem is that although the full season has been "watched" it appears it was only streamed, not downloaded. Or rather, that one episode was downloaded, and the rest streamed. I bought a season pass (so all the episodes at once) and the show was bought, not rented. How do I make Zune download, not stream, a show?

  • Unable to log in due to freeze, occasional error message

    - by Xianlin Xiong
    I'm new to Ubuntu. And I have some problems now. I downloaded Ubuntu 11.10 and burned it onto a CD. Then I load it in my conputer, it's easy. But when I finished those and restarted the computer, the problem comes: After I choose to log in the Ubuntu system,the screen stays in pink, and it can't jump into (about 30 min), and then I have no choices but to press Ctrl+Alt+Del to reboot. Another time I choose Ubuntu to log in, it shows on the screen that "BusyBox v1.18.4 ...... built-in shell ...... initramfs". However the Live CD works very well. What’s more, there is a Windows 7 partition on the hard drive. (Windows 7 is also okay.) But I leave more than 20GB on the hard drive to Ubuntu. When I installed Ubuntu, I only made two partitions (swap and /). I don’t know where the problems happened and how to deal with them. And I hope someone can help me out with the troubles.

  • Client/Server game even in solo: any big problem?

    - by Klaim
    I'm making a game which have strong basic design based on multiplayer but also should provide a really interesting and self-sufficient solo game. A bit like a real-time strategy game. The events and actions taken shouldn't be as massive and immediate as in a FPS, so you can also think the networking like for an RTS. It's a PC game, targetting Windows, MacOSX and Linux (Ubuntu & Fedora). It's programmed in C++, using a variety of open source libraries, so I have great (potential) control over the performances. So far I always considered that just making the game work with two applications, client & server, even in solo mode was ok. However, as I'm in the process of starting the network code I'm having doubts about if it's a good idea. I'm not a specialist so I might be missing something in my analysis. I see these pros and cons: Pros: The game works only one way so if I fix a bug it should apply on all game modes, whatever the distance with the server is; Basic networking issues would be detected early, including behaviour with the protection softwares (firewall) installed (i am not specialist so this might be wrong); Cons: I suppose that even if it should be really fast enough, networking client and server on the same computer would still be slower than no networking and message passing in (one) process memory. Maybe debugging would be more difficult? I don't have experience in this case but so far I assume that debugging with Visual Studio allows me to debug multiple process so it shouldn't be really different. Also, remote debugging. My question is: is there a big disadvantage that I missed? Or maybe there are advantages that I missed and that should encourage me to just continue with only client-server game sessions?

  • Windows XP SP3 dissapearing mapped drives

    - by Alan Spark
    I am running Windows XP Pro SP3 and I've got a few shares on my NAS that are mapped to reconnect automatically. I can access the drives soon after starting windows but after a period of inactivity I get the error "The local device name is already in use". This cannot be remedied until I restart the computer - I've tried disconnecting and re-mapping without success. This was working fine until I recently reinstalled Windows and I'm not sure what is going on. Any help would be greatly appreciated. Thanks, Alan

  • Changing languages rapidly causes Linux to crash.

    - by eZanmoto
    So I'm running Xmonad on my college computer (which runs Kubuntu) and whenever I leave my desk, instead of using x-screensaver which is incredibly buggy and slow, I just change to another workstation, open a terminal and change language to a language which uses symbols instead of letters, and then change back using an aliased command. For example, my .profile has the lines alias qwer="setxkbmap jp" alias *******="setxkbmap ie" where ******* is my password, using japanese characters. Changing languages seems to be much faster than running x-screensaver. The problem: rapidly changing languages seems to crash Linux; it just won't accept input (and it's not because the language hasn't changed back, nothing is output to the console). I can't use Ctrl+Alt+F1..F7, I can't "raise the elephants", anything, it just won't work. I'm just wondering, is this a known issue, and if so, is there something I can do about it?

  • Daemon Tools error (0xc0000006)

    - by Roberts
    I tried to reinstall Windows XP to Windows 7, but I could not install the video card drivers because the driver installation software only works on XP.I have launched the setup program with XP mode. After I installed the setup, I restarted the computer and Windows 7 wasn't booting.But that isn't the problem why I asked this question. The problem is that I have reinstalled my Windows 7 Ultimate to Windows XP SP3 and I wanted to install Dameon Tools.After installation I restarted the PC (as the setup wanted) and when the Daemon Tools launches it shows the error: Application failed to initialize properly (0xc0000006). Click OK to terminate the application.

  • What iPhone apps have I already purchased?

    - by torbengb
    I've bought many iPhone apps by now, some free and some paid. I've reinstalled my computer, and in the new installation, iTunes is completely blank. On first sync, iTunes downloads the apps that are currently installed on my iPhone. But what about all those apps that I have bought and aren't currently installed? Is there a way to re-download all my apps into iTunes? Where can I see a listing of all the apps I've ever downloaded? (Update: Apparently not all purchased content is restored - some things are inexplicably missing. You won't be charged anew for downloading them again, but you also won't be told what it is that you're missing. See here for details...)

  • 11.10 system crashes for no apparent reason [closed]

    - by varanoid
    I'm relatively new to Linux, and while I know a fair amount about computers and programming, it certainly isn't my specialty. I have a dual boot with Windows 7, and it has been working very well for me until recently. Just randomly the computer will freeze. The last time I was smart enough to keep the System Monitor open when it happened, and it looks like at the time of freezing "bash" and a bunch of other processes that I don't recognize seem to have flooded the memory. So it looks like my memory is getting overloaded and this is what is crashing the system, but I honestly have no idea what could be doing it. Generally I have a bunch of programs running, but they don't take much RAM or CPU: Transmission, Libre Office Writer, Firefox, Empathy, and Banshee. Sometimes I also have Text Editor and Terminal open, but it crashes regardless. When it crashes, it seems that all of the programs are working fine but things like windows, the taskbar, and operations like Alt+Tab just stop working properly or at all. Sometimes the mouse and keyboard freeze and I have to power off manually. Other than that I don't know what the problem is. The only irregularity I've experienced is that I can't download "Debian package management system" even though other updates download fine.

  • Syncing Large Directories/Filesystems using USB Drive [closed]

    - by Alan Lue
    Does anyone have a solution for syncing large directories/filesystems using just a USB flash drive (and specifically without using a network connection)? The objective is simply to sync a user directory between two computers. The contents of the user directory could amount to a large quantity of data—say, a quantity larger than could be stored on any single USB drive—but the aggregate size of changes that must be propagated by a single sync could easily fit on a USB drive. As an example, suppose a user directory is already synchronized between a desktop and a laptop computer. Here's a use case: Some changes are made in the user directory on the desktop. We mount a USB drive onto the desktop and copy whatever changes need to be applied to the laptop user directory in order to synchronize the desktop and laptop user directories. We now mount the USB drive onto the laptop and apply the changes. The desktop and laptop user directories are now synchronized. Any ideas? Alan

  • Black screen on Windows 7 right after opening Google Sketchup or Minecraft

    - by Aero
    I get a black screen on Windows 7 right after opening Google Sketchup or Minecraft. I presume there are other applications that cause this too - but I have not tried to open them. The window initially stops responding for a few seconds, before I get a black screen and my Skype call ends abruptly. I have tried waiting for a few minutes but nothing happens. I have to power down my computer and then boot it up again. This is becoming an annoyance, and I don't know what's causing it. Here are my specs, if it helps: My graphics card is an ATI RADEON XPRESS 1100. If you need any more info or if I've missed anything please ask. Thanks :-)

  • Mysterious "media" volume mounted on desktop Mac OS X

    - by Allen
    I have a mysterious volume mounted on my desktop that I can't seem to forcibly unmount. I've tried using umount and also diskutil, but it seems to automatically remount itself. I've copied my hdd with Time Machine, and copied it onto a new computer, and it also has the drive mounted on it. It's not pointing to anything and I can't open it, nor can I forcibily remove it by hand with rm -Rf. Any ideas? I noticed this problem after I upgraded to Mountain Lion from Lion. It causes problems because when I try to select a file using the built in Finder dialog box, it freezes for a few minutes because it tries to cache or read into the "media" mounted volume.

Domain with specific port is pointing on computer in local network (fixed ip) like: mydomain.com:87 -> 192.168.1.1 Local machine is running on win server 2008. Everything works fine on local network. But mydomain.com:87 is not working. Are there extra settings for win server to allow connection from outside? (Firewall is turned off while searching for working result.)

  • How to tell if my sound card is listed in Device Manager?

    - by Bruhan
    The sound on my computer suddenly stopped working. When I check Sounds and Audio Devices in the Control Panel, I get "No Audio Device" with everything grayed out. When I check the Device Manager under "Sound, video and game controllers" I see the following list: Audio Codecs Legacy Audio Drivers Legacy Video Capture Devices Media Control Devices MPU-401 Compatible MIDI Device Standard Game Port Video Codecs None of these looks like my sound card. Of course, my sound "card" is not really a sound card, it's integrated with the nVidia-nForce motherboard. I'm running Windows XP. So is one of the above my sound device, or is the OS not detecting it? If the latter, how do I get it to detect it?

  • OS X software updates download but don't install

    - by ridogi
    I've got three 10.6 computers that won't install OS X updates. Checking for new software will show about a dozen updates (Security updates, Safari, iPhoto, printers, etc) and if choose install it downloads them. After downloading and then clicking restart the computer sits at the purplish sky desktop with no progress bar, and then after about 3 minutes it goes back to the login window (without ever installing or restarting). If I then select check for updates the same updates will all be presented and I can repeat the process. Manually downloading and installing an update such as 10.6.8 combo updater works as it should, and then check for updates no longer presents that particular update as an option. This seems to be the result of some setting or 3rd party application as I've got 3 out 7 computers experiencing this exact same problem. What could cause this and how can I fix it?

  • Unity no longer loads in 13.04 for main user

    - by user152973
    When Ubuntu starts up, Unity fails to load (I can only see my desktop with no unity sidebar and no system bar in the top right). I tried the advice of Unity does not start in Ubuntu 13.04 which recommended the following commands: dconf reset -f /org/compiz/ unity --reset-icons &disown I ran the commands without errors an restarted the computer, but the problem persists. I am currently running Gnome. I have looked at other pages from the Google search "ubuntu unity failed to load 13.04", but the advice was similar to above and seems to be concerned with a system upgrade in April 18, 2013. I suspect my issue is something far more recent. Please give me advice on how to restore Unity on my account or at least figure out what the problem is. Thank you. Some information that might be relevant: -Unity has worked fine on 13.04 for the 6 months that I've had it until today. (November 10, 2013) -I have set up the update tool to automatically update when available. It is very possible that the system applied some updates without my knowledge. -Interestingly, Unity works fine on the Guest account. -I have made it so the system automatically logs me in at start-up. -This is a personal laptop. No one else has access to it. -I was not doing anything with the system settings or the terminal and have not installed any new software for the past 3 days. -I am running the System76 native Linux laptop Ultra Lemur. I did not contact their support yet because it seemed unlikely that this is a System76-specific error.

  • How to optimize a box2d simulation in action game?

    - by nathan
    I'm working on an action game and i use box2d for physics. The game use a tiled map. I have different types of body: Static ones used for tiles Dynamic ones for player and enemies Actually i tested my game with ~150 bodies and i have a 60fps constantly on my computer but not on my mobile (android). The FPS drop as the number of body increase. After having profiled the android application, i saw that the World.step took around 8ms in CPU time to execute. Here are few things to note: Not all the world is visible on screen, i use a scrolling system Enemies are constantly moving toward the player so there is alaways to force applied to their body Enemies need to collide between each others Enemies collide with tiles I also now that i can active/desactive or sleep/awake bodies. Considering the fact that only a part of the enemies are possibly displayed on screen, is there any optimizations i can do to reduce the execution time of box2d simulation? I found a guy trying an optimization based on distance of enemies from the player (link). But i seems like he just desactives far bodies (in my case, i could desactive bodies that are not visible). But my enemies need to move even when they are not visible on screen, and applying forces will not workd on inactive bodies. Should i play with sleeping bodies here? Also, enemies are composed by two fixtures and are constantly colliding with each others and with tiles but i really never need to get notified about that. Is there anything i can do to optimize this kind of scenario? Finally, am i wrong to try to run simulation at 60FPS on mobile and should i try to make it run at 30FPS?

  • Is it possible to pick out what applications that should run through a VPN in Ubuntu 9.10

    - by user31257
    Hi, I'm using Ubuntu 9.10 and I'm wondering if it is possible to pick out what applications that should use a VPN. Say for example that I want to route Transmissions connection through a VPN, but I also want to be able to access my computer over SSH via my usual static IP-adress ( running the SSH- deamon over my normal internet connection) . Is there anyway to do this? As I've been searching the web I found that at least it is possible to set whether you want both your internet connection and your "local network" to go through the VPN or if you want just the "local network" to go through it. I'm using the network-manager-pptp with the pptp- protocol.

  • Synchronisation software to find files that have moved paths within a folder?

    - by kpierce8
    Say I have a pictures folder which I reorganized on one computer. I'd like to use that directory as the base and compare it with another version on a backup drive. Will any Synchronisation/compare program find that a file in one folder has moved locations within a compare folder? For instance, say I reorganized my pictures from trips into folders by year with the trips folders inside each year folder. If I use a regular compare utility I wind up with two copies of everything that's moved in different locations.

  • is it okay to use random URLs instead of passwords?

    - by stew
    Is it considered "safe" to use URL constructed from random characters like this? http://example.com/EU3uc654/Photos I'd like to put some files/picture galleries on a webserver that are only to be accessed by a small group of users. My main concern is that the files should not get picked up by search-engines or curious power-users that poke around my site. I've set up an .htaccess file, just to notice that clicking on http://user:pass@url/ links doesn't work well with some browsers/email clients, prompting dialogs and warnings messages that confuse my not-too-computer-savy users.

  • Is running multiple databases on login going to make my Mac really slow?

    - by Walrus the Cat
    Sometime ago, I installed Postgres, and the Launch agent that causes it to run when I log in. Just now, I did the same thing for Mongo. I was just about to do it for Couch. I don't remember if I ever did it for MySQL, but I probably did. Mongo and Couch are just 'when I have time to look into it' sort of things, but I don't want to have to remember to start them when I do. I have a 2.4 Ghz processor and 8 GB ram. Is this sort of behavior going to significantly impact my computer's performance? Should I be scrambling to uninstall all but the database I'm currently using, or can I install all the things and run them all the time? Thanks

  • Where is the best place to teach myself a language, and which one?

    - by Lorinda
    Hello, I do not know any programming languages at all. I will self teach myself and need to know the best place to do so where I can learn from a most basic level. Where is a great place to begin learning a language? What language is best to learn first? Is it silly to learn Ruby first? Here, I came across someone saying that learning some of the higher languages can make you 'lazy' if you learn them first. Like Ruby amongst others. For my first language, my husband is advising me to learn Ruby (for his own personal interests). However, I need some independent advice of how to get started and what language I should learn first. I will eventually learn Ruby and then Rails. Four months ago, my husband ordered a text of objective C because he thought he would take it on. I flipped through and it was clearly starting at a place more advanced than where I am coming from. I have dabbled with a Ruby tutorial and I don't get it. I get what I am putting in is what I get, but I don't understand what is leading up to that. I need to know ALL the rules first. I then looked up computer languages and stared researching binary code which helped a lot, but not where I want to start. I don't have a lot of time right now in my life (with four kids) to go back that far. If I were going to school, that would be different. Any advice you could give is most welcomed.

  • I screwed up, exit in .bashrc

    - by camel_space
    I put "exit" in my .bashrc file. I don't have physical access to the machine so to connect to it I use ssh. I don't have root privileges. Every time I connect to the server, the connection automatically closes. So far, I've tried: Overwriting .bashrc with scp and sftp. The connection closes before I can do anything. Using a few different GUI programs to access ssh (connection closes) Overwriting the file with ftp. (can't use ftp) From my home computer $ ssh host "bash --noprofile --norc" (connection closes) $ ssh host "mv .bashrc bashrc_temp" (connection closes) $ ssh host "rm .bashrc" (same thing) $ ssh host -t (connection closes) Is there anything I can do to disable .bashrc or maybe overwrite the file before .bashrc is sourced?

  • Looking for a way execute a task on all files in a directory (recursively) on Windows

    - by stzzz1
    I have a huge number of mp4 video files that needs to have a volume boost. I need a way to execute a ffmpeg audio filter on all files in a specified base directory (and in subdirectories as well). My problem is that I'm working on a Windows computer and I have no knowledge of its shell syntax. I would like to do the equivalent of what this bash script does : TARGET_FILES=$(find /path/to/dir -type f -name *.mp4) for f in $TARGET_FILES do ffmpeg -i $f -af 'volume=4.0' output.$f done I spent quite some time this afternoon looking for a solution but the recursive nature of what I need (that is so simple with find!) isn't too clear. Any help would be greatly appreciated!
