• Windows 7 and 11.10 side by side from scratch what am I doing wrong?

  - by Bill.Caffery

  I have tried everything I can think of at this point and I'm at a total loss. I have a 2TB drive I want to install Windows 7 and 11.10 (both are 64 bit) side by side, but once I install Windows it must need gpt to work or something because no matter how many times I've removed it, it always returns. If I use gdisk and set the disk as mbr, Windows won't load. Now this last time I ran gdisk and tried to boot into Windows before I installed Ubuntu all the way and ended up at a grub rescue prompt. Any help please? Also let me say I have been searching and reading for days and have tried everything I can find to make this work so this isn't a one time event, it's continual.

• Installing package + dependancies and removing them all

  - by Sman789

  I currently use Xubuntu and was considering installing/trying GNOME Shell or Cinnamon by installing their respective metapackage. However, doing so would result in a massive number of dependencies being installed which would be almost impossible to remove individually at a later date if I decided I didn't like it. I wonder, therefore, if there is a way that I can track which packages Synaptic automatically downloads as part of the process and create a script of some sort to remove them all as well. I could then rest assured that if I don't like any of my new desktop environments, I can remove them in full without leaving a load of other applications and libraries lying around. Thankyou for any help! :)

• What is the current frequency of my processor (CPU-Z equivalent)?

  - by Anake

  Is there a ubuntu program like CPU-Z which will show me the actual frequency of my processor? I do a fair amount of scientific computing which leads to me running my programs for up to 10 hrs. To alleviate this problem a little I overclock my CPU. However I can't see what the actual clock of my processor from within ubuntu which means I either have to restart and look at the bios or load into windows. If there was an applet or command line command to find out this information it would be very helpful. Thanks for your help

• Extracting, Transforming, and Loading (ETL) Process

  The process of Extracting, Transforming, and Loading data in to a data warehouse is called Extract Transform Load (ETL) process.  This process can be used to obtain, analyze, and clean data from various data sources so that it can be stored in a uniform manner within a data warehouse. This data can then be used by various business intelligence processes to provide an organization with more of an in depth analysis of the current state of the company and where it is heading. A standard ETL process that might be used by a health care system may include importing all of their patients names, diagnoses and prescriptions in to a unified data warehouse so that trends can be spotted in regards to outbreaks like the flu and also predict potential illness that a patient might be affected by based on other patients with similar symptoms.

• Turned off my computer and o it's opened up in grub. How do I tell it to boot into lubuntu?

  - by Magpie

  It's just a commandline. I have tried my usual trick of sticking a usb with lubuntu in there to see if I can boot from my usb but I get a boot error (I normally wouldn't using that usb). GNU grub version 2.00-7ubuntu11 also just using basic things I know I hits ls then tried boot hd0 but it says: you need to load the kernel first I have no idea how to do this. I looked at the commands and most of them hve obscure names that are not helpful. UPDATE: I hit exit and that allowed be to boot from usb. Hopefully I will be able to find what I need to install to get it booting normally again from there.

• Problem with Arcam rpac and Ubuntu 12.04

  - by user108393

  I have recently (?mistakenly) purchased an Arcam rpac USB DAC for my Ubuntu (12.04) PC. I have torn out all but 3 of my hairs trying to get this to work and have had absolutely no luck so far. I can see the Arcam USB audio device when i run aplay -l, however I cannot see it listed under the Sound settings. I can see the soundcard device when running alsamixer also, but if I try and select it, alsamixer crashes, stating "cannot load mixer controls: Invalid argument". Any ideas how to get this working (if it's even possible)? Does anyone else out there have the rpac with ubuntu? Thank you! Aman

• How to revert to 10.04

  - by Keith Mastin

  Since "upgrading" to 12.10, the multitude of problems and slowness has wondering me , if I'm running windows, so I want to take it back to 10.04. Just some of the problems that we never had in 10.4: Can't play YouTube and chat at same time; Can't open more than 5 photos in GIMP without constant grayouts; Can't easily close apps or programs on desktop; Can't Use Avidimux and Audacity at same time, CPU load stays at 100%; New Gnome is not nearly as intuitive as classic, focus is all over the place, have to constantly switch to have the focus on right window of same program (either browser), etc. Do I need to wipe my system partition and start over, or is there an easier way to downgrade?

• Are HTTP requests cached? [closed]

  - by nischayn22

  Many HTTP requests are sent repeatedly by browsers on almost every page load, such as requesting the jQuery .js file etc. Since these are already used on too many sites doesn't modern browsers keep a cache for this? I am thinking of a system where the browser has a cached copy of the .js file used very very frequently. On a new request for the .js file, it sends the server a request for a hash of the .js file (provided the server can reply to that) and compares the returned hash with the cached copy's hash... rest is intuitive.

• Invoking JavaScript from Java

  - by Geertjan

  Here's an Action class defined in Java. The Action class executes a script via the JavaFX WebEngine: @NbBundle.Messages("CTL_AddBananasAction=Add Banana") private class AddBananasAction extends AbstractAction { public AddBananasAction() { super(Bundle.CTL_AddBananasAction()); } @Override public void actionPerformed(ActionEvent e) { Platform.runLater(new Runnable() { @Override public void run() { webengine.executeScript("addBanana(' " + newBanana + " ') "); } }); } }How does the 'executescript' call know where to find the JavaScript file? Well, earlier in the code, the WebEngine loaded an HTML file, where the JavaScript file was registered: WebView view = new WebView(); view.setMinSize(widthDouble, heightDouble); view.setPrefSize(widthDouble, heightDouble); webengine = view.getEngine(); URL url = getClass().getResource("home.html"); webengine.load(url.toExternalForm()); Finally, here's a skeleton 'addBanana' method, which is invoked via the Action class shown above: function addBanana(user){ statustext.text(user); } By the way, if you have your JavaScript and CSS embedded within your HTML file, the code navigator combines all three into the same window, which is kind of cool:

• Battery life decreased after upgrade to 11.04

  - by bruno077

  After upgrading from Ubuntu 10.10, my battery life has decreased dramatically. There was a bug in Ubuntu 10.10 where the Load Balancing Tick and Kworker would interrupt and wake-up the cpu too much, and this wasn't normal. I applied a gnome-power-manager fix back then, following this question, which leads to this bug report, and battery life increased to 3.5 hours. I'm getting around two hours of battery-life in Natty, and calling Intel's powertop reveals that this bug is back. Is there a fix for Natty yet? I have a Core 2 Duo ULV, Thinkpad Edge 13

• Quantal upgrade broke my gnome-shell!

  - by hwjp

  Just updated to quantal 12.10, and Unity works fine, but and I can't get gnome-shell to work :( Some symptoms: when using gdm as the default, it decided to display everything in chinese. When attempting to log in, it accepts the password, and then seems to crash when trying to load my desktop, and seems to restart gdm and send me back to the login screen when switching to lightdm as the window manager, it gets a little further (and in english), bringing up a desktop, but a broken one -- the propeller key doesn't bring up a menu, there's no menubar or notifactions area. i can do a few things, like bring up a terminal with ctrl+alt+t, and launch eg firefox from there, but not much else. I have tried uninstalling gnome-shell, deleting /etc/gdm, and reinstalling Any other suggestions? Which log files to look at for example?

• reading parameters and files on browser, looking how to execute on server

  - by jbcolmenares

  I have a site done in Rails, which uses javascript to load files and generate forms for the user to input certain information. Those files and parameters are then to be used in a fortran code on the server. When the UI was on the server (using Qt), I would create a parameters file and execute the fortran code using threads so I wouldn't block the computer. Now that is web-based, I need to make the server and browser talk. What's the procedure for that? where should I start looking? I'm already using rails + javascript. I need that extra tool to do the talking, and no idea where to start.

• Assigning a different texture based on picking(XNA)

  - by Thomas Carmichael

  I'm making a game using XNA. I have some simple objects like cube and sphere, and I would like to change the texture of one face of these objects based on picking. That is, when the cursor is over one face, it turns red. The only way I've seen to do this is to overload the content processor as here: http://xbox.create.msdn.com/en-US/education/catalog/sample/picking_triangle but it seems like it shouldn't be this complicated. I'm using .x models, and would like to be able to implement this for more complex models in the future beyond cubes/spheres/etc. Is this the best/only way to go about it? I'll figure that out if that's what is necessary, but it seems that there would be a simpler solution to load a different texture to a face than I've seen, I just don't know what it is.

• Black screen with blinking cursor after dual boot install 14.04

  - by chillstream

  I have just installed Ubuntu 14.04 on my toshiba laptop along side Windows 7. When the menu comes up to choose which OS to boot into, I can easily boot into Windows 7. I cannot successfully boot into Ubuntu. All I get is a blinking cursor on a black/purple screen. I attempted the nomodeset trick, which was a bit more successful. I got a screen with a lot of code, but then it stopped with a blinking cursor at the bottom and wouldn't load anymore. As a last resort, would returning my laptop to factory settings get rid of linux and the partitions made to the drive? I already did this to my laptop when it was just windows, which is why I thought I might as well try to add Ubuntu. But it's a lengthy process, and if it won't get rid of the partitions and ubuntu, I won't bother. I appreciate any help ~many thanks

• How do you enhance your websites speed without compromising the design and access?

  - by Thorn007

  How do you enhance your websites load speed without killing the design and accessibility? File compression, CDN, Gzip? What are the best tools for doing so? For example, Google has optimized their site without compromising the design. Also, many website can kill the purity of their images with compression. Is there a way, more or lest best practice, to increase speed without compromising the design and accessibility? Note: sorry for being so vague but I don't know how else to phrase this question.

• Open file with java application [migrated]

  - by Giaphage47

  I am using Ubuntu. I would like to have a user be able to double-click (or whatever they have set to open a file) on the save file for a java game i'm making, and have the game start and automatically load the save. How could I make the game launch instead of opening the file, and then pass the save's file name or location as an argument? Would i have to have the game create a new mime type the first time it ran, or something similar, so that Ubuntu knows what to do with the save when the user tries to open it?

• Logitech Wireless Keyboard & mouse not working aftesr upgrade to 12.04?

  - by deerjay99

  I upgraded my Dell Dimension 9200C to 12.04 Precise Pangolin with no issues, I ran it fine for a night but when I went back in a couple days later my Logitech Wireless Keyboard K350 and M510 mouse weren't active when booted. I can boot into an older version from the main the boot screen the mouse and keyboard work, but the network stack is gone. It says the networking manager on this version is not compatible. I'm scratching my head, it isn't the mouse and keyboard, they work fine on my dual boot, and they load fine in Knoppix. They did work fine on 12.04 for 1 night. Open to suggestions before I re-install completely.

• Cocos2D Command-Line Application

  - by Hasyimi Bahrudin

  Is it possible to create a terminal application which uses cocos2d? I've tried to make one using cocos2d 2.x, but it requires a MacGLView to be initialized. I need it so that I could program a terminal application that generates a screenshot given a TMX file and an optional preferred width or height parameter (for resizing). Then I can automate the generation of map previews for my game, instead of manually taking screenshots. It's not practical to load the actual TMX and resize it inside the game (what I'm currently doing), because each TMX file has 7 layers, my tile sheet is huge, and I have lots of levels.

• Any good stories or blog posts of a startup's server/stack evolving as they got bigger? [closed]

  - by user72245

  I know lots of startups often go for practical, simple, efficient. So maybe tossing a Ruby program on a basic Apache server. Get some users up and running, etc. Then Ruby starts to not be fast enough, so they throw more servers at the problem? And load balancing or something? And then when stuff gets REALLY crazy, language changes, etc? I'm looking for someone who has cleanly and simply told their own company's story like this. Are there any good ones?

• Slow internet connection with a Digicom Wireless 11n 300m (rt2800)

  - by beboka8

  After upgrading to ubuntu 11.10 the speed of my internet connection has considerably reduced. I surf on internet using a wireless usb adapter Digicom Wireless 11n 300m which works with rt2800usb driver. The fact is, on the installation cd there's no tracks of that driver but instead of it there is another one called rt2870 which I tried to load using ndiswraper, but it did not recognize any hardware. I'm not sure the solution of my problem is simply changing the driver, but I have no other ideas. Can anyone help me?
