• External monitor on old Dell 700m?

  - by Adam Henne

  Okay, linux noob. I installed 10.04 on an old Dell 700m in hopes of using it as a media center device. That seems to work great, except now it won't output to the external monitor. VGA cable works fine, TV recognizes other computers fine, it's the laptop that won't output. Turns out that the 700m, unlike every other computer out there, doesn't have a Fn hotkey to switch monitors. The only way to do it in Windows was to go through the Control Panel. In Ubuntu, though, the Monitor setup won't detect or recognize any monitors. The laptop display works fine, but I can't adjust or add anything. I did a little research and found suggestions for older Ubuntu builds involving the xorg.conf. I tried one out, in spite of my unfamiliarity, and it's screwed the whole display big time. I can fix that with a clean reinstall, that's no problem, but I'm cautious about editing xorg again. Any suggestions? Thank you!

• Cannot create a neutral unit with a trigger

  - by Xitcod13

  I've been playing around with the starcraft UMS (Use map settings) for a while and usually i figure things out pretty quickly when im stuck. Alas not this time. I'm trying to place a neutral unit (player 12) using a trigger. It refuses to work. I'm using Scmdraft 2.0 as my editor (but i cant get it to work in other editors either) (all neutral units placed before the game starts are visible and all other triggers work fine. Also i created a text msg and it does displays it in-game so the trigger triggers ) For testing I created a trigger that looks like this: Player: neutral (i tried neutral players player 1 and all players as well) Condition: -always Action: -Create *1 Terran Medic* at '*location 022*' for *Neutral* (also tried neutral players) When I start the game nothing happens. Here is what I tried: I tried placing a start location for neutral player (player 12) I tried changing the owner under map properties of player 12 to neutral and computer from unused which was the default. Although it seems like it should be a common enough problem, I don't see it in any FAQ and I cant find anything about it when I Google it. Thanks in advance.

• Use a SQL Database for a Desktop Game

  - by sharethis

  Developing a Game Engine I am planning a computer game and its engine. There will be a 3 dimensional world with first person view and it will be single player for now. The programming language is C++ and it uses OpenGL. Data Centered Design Decision My design decision is to use a data centered architecture where there is a global event manager and a global data manager. There are many components like physics, input, sound, renderer, ai, ... Each component can trigger and listen to events. Moreover, each component can read, edit, create and remove data. The question is about the data manager. Whether to Use a Relational Database Should I use a SQL Database, e.g. SQLite or MySQL, to store the game data? This contains virtually all game content like items, characters, inventories, ... Except of meshes and textures which are even more performance related, so I will keep them in memory. Is a SQL database fast enough to use it for realtime reading and writing game informations, like the position of a moving character? I also need to care about cross-platform compatibility. Aside from keeping everything in memory, what alternatives do I have? Advantages Would Be The advantages of using a relational database like MySQL would be the data orientated structure which allows fast computation. I would not need objects for representing entities. I could easily query data of objects near the player needed for rendering. And I don't have to take care about data of objects far away. Moreover there would be no need for savegames since the hole game state is saved in the database. Last but not least, expanding the game to an online game would be relative easy because there already is a place where the hole game state is stored.

• How can I check myself when I'm the only one working on a project?

  - by Ricardo Altamirano

  I'm in between jobs in my field (unrelated to software development), and I recently picked up a temporary side contract writing a few applications for a firm. I'm the only person working on these specific applications. Are there ways I should be checking myself to make sure my applications are sound? I test my code, try to think of edge cases, generate sample data, use source control, etc. but since I'm the only person working on these applications, I'm worried I'll miss bugs that would easily be found in a team environment. Once I finish the application, either when I'm happy with it or when my deadline expires, the firm plans to use it in production. Any advice? Not to use a cliche, but as of now, I simply work "to the best of my ability" and hope that it's enough. Incidentally, I'm under both strict NDA's and laws about classified material, so I don't discuss the applications with friends who have actually worked in software development. (In case it's not obvious, I am not a software developer by trade, and even my experience with other aspects of information technology/computer science are limited and restrained to dabbling for the most part).

• 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?

• 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?

• Outlook 2010 : "An error occurred when setting schedule permissions"

  - by francisswest

  Computer: Windows 7 x64 Enterprise. Office 2010 with Outlook 2010. Exchange account and a couple of IMAP accounts connected to the Outlook profile. Error: When attempting to share the calendar with anyone (selected from the address book) by click on "Calendar Permissions" seen here You can add or remove people without issue, except that no matter what, even if nothing is done, just opening the sharing window and closing it, you get an error message that says "An error occurred when setting schedule permissions" Verified that the issue doesnt actually effect the sharing, or the general setting of permissions. The error however is disconcerting to my user, and I would like to alleviate the problem if possible. Thanks!

• 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 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.

• 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.

• Error Formatting Memory Card

  - by Kirby Fromm

  I just tried to look at some of my pictures on my sony cyber-shot dsc-tx5, with a Lexar platinum II 16 GB memory stick, and it is now saying I have a formatting error every time I turn the camera on. The card and Camera are both 3 months old and have worked perfectly before. I tried to check the card on my computer and it says there is an error, so the camera is working but the card is not. Does anyone know how I can fix this to get the pictures off of the card?

• 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 :-)

• Strange ports on default install of W7

  - by Sabre

  I have a base new install of windows 7, and when I went to look for something else I saw the attached netstat output. What concerns me is that this is Windows + Truecrypt + drivers, nothing else installed. The sequential high ranged ports belonging to several different seemingly not out of place services seemed odd. So I torched the install, used Active@ to scrub the disk, re-downloaded the ISO from MSDN, and did a fresh reinstall, viola, they are there again. It just seems out of place, I have seen a many netstats over the years, this one just strikes me as odd, so I started thinking rootkit? (JUst FYI, when I reloaded I named the machine "Error" so that is why the task manager reads the computer name as such.) So I would like to know if anyone else could explain it, and therefore is may be normal, or would they be worried as well, and should I start considering I have some very strange thing occuring on my network?

• 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?

• 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.

• VMWare Workstation 8, Sharing a VM without copying them to "Shared VMs location"

  - by Stebi

  I have a host computer (Win7-64) with three different harddrives. It runs several VMs which are distributed among those harddrives for a better performance. Now with VMWare Workstation 8 it is possible to "share" the VMs. I'd like to use this feature, but I have to convert the VMs to "Shared VMs". When I try this WMWare forces me to copy the VMs to one predefined folder, thus making my effort of distributing the VMs among the harddrives meaningless. Is there any possibility to keep the VMs where they are and share them anyway?

• What is the best objective way to measure language popularity trends? (What's better than TIOBE?)

  - by Eric Wilson

  The best way to get data on computer language popularity that I know is the TIOBE index. But everyone knows that TIOBE is hopelessly flawed. (If someone provides a link to support this, I'll add it here.) So is there any data on programming language popularity that is generally considered meaningful? The only other option I know is to look at the trends at indeed.com, which is inherently flawed, being based on job postings. It isn't like I would make a future language decision solely based on an index, but it might provide a useful balance to the skewed perspective one obtains by talking to ones friends and colleagues. To illustrate that bias, I'll point out that based on the experience of those I personally know, the only languages used professionally today (in order of popularity) are Java, C#, Groovy, JavaScript, Ruby, Objective C, and Perl. (Though it is evident that C, C++ and PHP were used in the past.) So my question is, everyone bashes TIOBE, but is there anything else? If so, can anyone explain how we know the alternative has better methodology? Thanks.

• 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...)

• Wallpapers of only some users being dynamically loaded in LightDM

  - by Kazark

  As this answer explains: Ubuntu 12.04 Unity greeter has introduced selected user dynamic background, that means that when selecting a user from the available users list the background will change to reflect the selected user's desktop background. However, I am puzzled, because in my experience this isn't consistently true. On one of my family members' computers, where there are three users, only one of the users' background shows in LightDM. None of the users are newly created. The user whose background is showing has a custom background; one of the users whose background doesn't show also does; and the other one who doesn't has the default switching wallpaper set. It is not a clean install but has been incrementally upgraded from about 8.04. Any idea what could be happening? This is a similar question, though we're also having the opposite problem (default wallpapers not showing). (I do not have access to the computer mentioend above at the moment; when I do I will use some of the criteria given there to analyze the problem further.)

• 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.

• View apache server across virtual machine?

  - by Mark

  I installed VirtualBox on my Windows 7 machine. Through VirtualBox, I installed Ubuntu 9.10 with apache2. I can view http://localhost from Ubuntu, but is there anyway I can view it from my windows machine too? i.e. run the apache server on ubuntu, and view it from windows? I figured it would open a port or something that would be visible to my whole computer regardless of its virtualness, but I guess not. How do I get around this?

• 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

• Reasons for Wi-Fi to be slower on Ubuntu compared to Windows?

  - by den-javamaniac

  I'm using 64-bit Ubuntu 12.04 and Windows 7 64 bit – dual boot on the same computer. Connecting to the same wireless network. And it turns out that on Windows I get a more stable and stronger signal than on Ubuntu. To my knowledge there's a router which serves as a gateway and then there's a cable connected to the router which goes further to ISP, so the results for both OS should be the same. I've tested the issue on both OSs at various times and it gave me the same result. The question is why? Why Ubuntu networking is worse than that of Windows?
