• How to shrink Windows partition with unmovable files in dual boot installation

  - by Tim

  To install Ubuntu alongside Windows 7, I have to shrink Windows 7 partition C:. But due to some unmovable files, I cannot shrink as much as I plan by using Windows own shrinking tool. I guess many of you who have both OSes on the same hard drive must have similar experience. How to solve this problem? Any reference that can help is also appreciated! Thanks and regards! UPDATE: I have identified what unmovable file currently stop further shrinking: \ProgramData\Microsoft\Search\Data\Applications\Windows\Projects\SystemIndex\Indexer\CiFiles\00010015.wid::$DATA If I understand correctly, the file belongs to Windows Search. Can I set up somewhere in Windows system settings to temperately eliminate the file and similar ones (because there are many similar files under the same directory which I guess will also stand in the way of shrinking and unmovable by defrag)?

• Error installing gPodder

  - by Ron Webb

  A few weeks ago (newbie alert!) I started using XUbuntu 12.04 with Xfce 4.8. I'm trying to install gPodder Podcast Client (see https://launchpad.net/~thp/+archive/gpodder). I've added the PPA via terminal commands as instructed. When I click the Install button in the Ubuntu Software Centre I get the following error: Package dependencies cannot be resolved This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time. Details: The following packages have unmet dependencies: gpodder: Depends: python-webkit but it is not going to be installed What do I need to do? Just to make thing more complicated -- I'm not sure, but before I found the launchpad.net link, I think I may have tried to install gPodder from the default Ubuntu repositories (also unsuccessfully). There may be remnants of the previous attempt still installed, which may be blocking the new install. Where/how can I find them?

• Is it practical to have perfect validation score on HTML?

  - by Truth

  I was in a heated discussion the other day, about whether or not it's practical to have a perfect validation score on any HTML document. By practical I mean: Does not take a ridiculous amount of time compared to it's almost-perfect counterpart. Can be made to look good on older browsers and to be usable on very old browsers. Justifies the effort it may take to do so (does it come with some kind of reward on SEO/Usability/Accessibility that cannot be achieved in a simpler way with almost-perfect validation) So basically, is perfect validation score practical on any HTML document?

• How can I get my game to show up in the Games Explorer on Windows?

  - by Kraemer

  I want to create an installer for a game which allows for an icon to be put in the Games Explorer for Vista and Windows 7. I have created the GDF, then built the script for project and obtained the .h, .gdf and .rc files. But I can't compile (using Visual Studio 2010) the .rc file into an executable to be used after that in order to create the installer. I get the following error after I set the executable path: "Could not load file or assembly'Microsoft.VisualStudio.HpcDebugger.Impl, Version 10.0.0.0, Culture=neutral, PublickKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified." Any ideas what I'm doing wrong?

• Starting old computer - nothing shown on screen at boot

  - by Jonas

  I'm trying to start an about 10 years old PC computer. But nothing is shown on the screen, and it beeps everytime I press a key on the keyboard. I can press Ctrl+Alt+Del to reboot the computer. The monitor is newer and seem to work with other computers. I don't see anything from POST/BIOS at start or later. I have tried to change to another graphic card, but it didn't change anything. What can I do to solve this problem? Update: I have now tried with another computer (the one where the "another graphic card" came from) and I got the same problem. I doesn't show anything on the screen. Both these computers had a GeForce2 MX 400 graphic card. I tried with another computer screen it didn't work - it was showing "signal out of range". So is the graphic card GeForce2 MX 400 too old for newer TFT-monitors? I tried with a third computer so I know that the monitors are working, and both monitors work fine with that computer.

• what is the purpose of arrows?

  - by Simon

  I am learning functionnal programming with Haskell, and I try to grab concepts by first understanding why do I need them. I would like to know the goal of arrows in functional programming languages. What problem do they solve? I checked http://en.wikibooks.org/wiki/Haskell/Understanding_arrows and http://www.cse.chalmers.se/~rjmh/afp-arrows.pdf. All I understand is that they are used to describe graphs for computations, and that they allow easier point free style coding. The article assume that point free style is generally easier to understand and to write. This seems quite subjective to me. In another article (http://en.wikibooks.org/wiki/Haskell/StephensArrowTutorial#Hangman:_Main_program), a hangman game is implemented, but I cannot see how arrows makes this implementation natural. I could find a lot of papers describing the concept, but nothing about the motivation. What I am missing?

• How to name setter that does data conversion?

  - by IAdapter

  I'm struggling with how to name this method, I don't like the "set" prefix, because I feel it should be reserved for normal "dumb" setters and some tools might not like it (i did not check it in checkstyle, pmd, etc., but I got a feeling they won't like it.) for example (in java, but I feel its language agnostic) public void setActionListenerClicked(boolean actionListenerClicked) { this.actionListenerClicked = actionListenerClicked ? "1" : "0"; } The only purpose of this method is ONLY to set, this method is needed and cannot be joined with any other (because of framework used). P.S. I DO know that question is similar to How to name multi-setter?, but I feel its not the same question.

• How do I use Brasero to burn a movie in DVD format?

  - by Ants

  I have to present an assessment for my Uni course in the form of a DVD movie (so it can be played on a DVD player) but so far, Brasero doesn't seem to be doing it. For example, I left it for over an hour today (as it said it was burning) and the DVD came out empty. Other times, it flat out says it cannot burn the DVD. I am running Ubuntu 10.10, I have ubuntu restricted extras installed and the Medibuntu packages that allow me to watch DVDs. Any ideas?

• SharePoint Apps a word of caution

  - by Sahil Malik

  SharePoint 2010 Training: more information Lucky for SharePoint, it is the first foray into this brave world where the browser is masquerading as an operating system. For the very first time, with SharePoint 2013, we will have apps from different vendors, talking to different domains live in the browser. Sound fun eh? Well, all is hunky dory until you consider that browsers don’t have concepts such as process isolation, encryption, obfuscation etc.. Stuff that we are so used to in operating systems that we don’t even think about it. Browsers have JavaScript, and broken HTML5 – it is not secure! In fact, in the current technology spectrum you cannot achieve anything other than laughable security at message level without involving a plugin or some sort of thick code like Java. The only security worth it’s salt in pure html/javascript scenarios, still, is transport security – and that’s it. Read full article ....

• How can I launch Matlab 2012 on Ubuntu 12.04?

  - by Mattia

  I have a problem with the MATLAB 2012 installation. After having installed it using alt+f2 and having used gksudo nautilus I have installed MATLAB in the correct folder which is: /usr/local/MATLAB/R2012a Then I inserted the license and the window told "activation complete" or something like that. This made me happy, but only for a while because as soon as I try to search for Matlab within the applications I cannot find it and neither if I try to run matlab into terminal it says: command not found Can someone help me!? Tanks in advance!

• How can I locate the frames of a spritesheet PNG based on this PLIST data?

  - by kitsune

  Someone asked me to reskin a certain game. Now he only sent me the whole sprite PNG and PLIST files of the sprites. He instructed me to rename each sprite with the same name corresponding to each original sprite. The problem is, he gave me the whole sprite sheet instead of each individual sprite and the PLIST. Now yes, I can read the PNG filenames from the PLIST, but I cannot rename the reskin sprites I did because I'm not sure which sprite is boy_gun_3_3.png; there are multiple guns, I don't know which is which. Is there a way to extract individual accurately named individual PNG files from the single sprite sheet using the PLIST?

• Should I use float, double, or decimal for stats, position, etc?

  - by Ryan Peschel

  The problem with float and double is that they are not exact. If you are to do something like store replays, the values would have to be exact. The problems with decimal is that they are approximately 16x slower (confirmed by searching and personal testing) than floats and doubles. Couldn't Vector2s be another problem because they use floats internally for all the components? How do other games solve this problem? I'm sure they must use floats and doubles but aren't they not deterministic across platforms and different architecture? The replay files for games like SC2 run in a linear fashion so you cannot skip ahead so how do they solve the determinism issue with floating point numbers?

• why is it a risk to clone a LUKS container?

  - by laramichaels

  I recently installed Ubuntu onto an encrypted partition using the LUKS+LVM combination that the 'alternate' installer offers. Now I want to create backups of my HD. From the LUKS FAQ: 6.15 Can I clone a LUKS container? You can, but it breaks security, because the cloned container has the same header and hence the same master key. You cannot change the master key on a LUKS container, even if you change the passphrase(s), the master key stays the same. That means whoever has access to one of the clones can decrypt them all, completely bypassing the passphrases. How can the existence of a perfect clone of my encrypted HD break security if it contains the exact same information as my live encrypted HD? In which sense does keeping updated clones of my LUKS-encrypted HD around "break security"?

• removing ubuntu from a laptop (corrupted ubuntu)

  - by Ron

  I wanted to update my (very old) Ubuntu installation on my dual boot laptop. The other OS is win7. However, when I tried to boot into it I got: \ubuntu\winboot\wubildr.mbr cannot be loaded. Status 0xE0000000C. I assume the mbr is the master boot record for the Ubuntu installation. I looked at my C: drive and there's a WUBILDR and WUBILDR.MBR file there. Is it as simple as deleting them? ALSO, I just noticed there is no UBUNTU partition. If I delete these files and then get rid of the startup option for Ubuntu, is that all I have to do? (My goal is to have an up-to-date Ubuntu OS alongside Win 7).

• replacing kernel on non-booting ec2 instance

  - by TheToolBox

  So I had an amazon ec2 instance crash during the update to 14.04LTS. Frustratingly, it appears the kernel might be bad (or at least that's what the log below says to me, I could totally be wrong). I'm able to mount the volume to another, working server, chroot the broken volume, and sudo apt-get remove linux-headers-3.MOSTRECENT. Unfortunately though, when I try sudo update-grub, it comes back with /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). What am I missing? Here's the log from the server's attempted bootup: [H[J Booting 'Ubuntu 14.04 LTS, memtest86+' root (hd0) Filesystem type is ext2fs, using whole disk kernel /boot/memtest86+.bin ============= Init TPM Front ================ Tpmfront:Error Unable to read device/vtpm/0/backend-id during tpmfront initialization! error = ENOENT Tpmfront:Info Shutting down tpmfront xc: error: panic: xc_dom_core.c:621: xc_dom_find_loader: no loader found: Invalid kernel xc_dom_parse_image returned -1 close(3) Error 9: Unknown boot failure Press any key to continue...

• How to safely move where itunes saves music/iphone apps/and meta data to another internal Drive?

  - by GingerLee

  In the past, when I have moved my itunes data from one computer to another, I usually just follow these steps: Copy the contents of two folders: %USERPROFILE%\Music\iTunes %USERPROFILE%\AppData\Roaming\Apple Computer 1) Install iTunes on the new computer, start it and close it (don't let it search for music). 2) Copy all the files in the above folders from old PC to new PC. 3) Start iTunes and authorize the new computer (and deauthorize old one). 4) Before syncing, update all iphone apps to current versions on both my iphone and in itunes. 5) The Sync. The above steps always work for me, and basically Itunes on my new PC works exactly as it did on the old PC. My Question: In the hopes of bybassing the above steps in the future, I would like to just have Itunes use another internal Drive that I use for file storage (e.g. D:/) as the path for the above two directory? Then if I move to new PC again, I could just setup itunes to use the correct path. Is that possible yet with minimal implications? If so how?

• Outlook 2010 Crashing Unpredictably

  - by cbkadel

  Very often when I open up Outlook 2010 and start doing actions in it, it will hang and become non responsive. I have tried letting it finish, but it never does come back (up to 20 minutes of letting it try). I generally have to restart Outlook and try again. Usually after about an hour of doing this, Outlook somehow snaps out of it and works for the rest of the day. It's generally in the morning (though I doubt that's the key variable). Generally, the emails that cause problems are HTML/formatted, but not always. What I've done so far to troubleshoot: Install Latest Outlook Hotfix (I think Dec 14, 2010) Start Outlook in Safe Mode Neither of those steps seem to make a difference. Usually - after about 10-15 restarts of Outlook on any given day, then it starts working thereafter. My next step is to uninstall/reinstall Office 2010, but I'm hoping someone has seen this and knows what to do about it - though not sure. My configuration is like this: Microsoft Online Services (using Microsoft's Sign In App) - Connecting to Exchange I have two other Exchange accounts in this profile (new feature in 2010) connected through Outlook Anywhere. Life Meeting Conferencing Add In I've disabled the People tab/add in. I've disabled the "Send to Bluetooth" add-in. Not sure what else to do. Thanks in advance.

• Which creative framework can create these games? [closed]

  - by Rahil627

  I've used a few game frameworks in the past and have run into limitations. This lead me to "creative frameworks". I've looked into many, but I cannot determine the limitations of some of them. Selected frameworks ordered from highest to lowest level: Flash, Unity, MonoGame, OpenFrameworks (and Cinder), SFML. I want to be able to: create a game that handles drawing on an iPad create a game that uses computer vision from a webcam create a multi-device iOS game create a game that uses input from Kinect Can all of the frameworks handle this? What is the highest level framework that can handle all of them?

• Permissions depending on parameters passed to application

  - by Engineiro

  I have a java app that writes to a very important table I have. This is sudo protected, but this app takes a parameters for where the output should go. The default is the REAL DEAL but the "output" parameter takes priority over the default, so if a user provides a path that they have write permission for, say: /home/username/mystuff then I would like for users to be allowed to write to these directories. The app is launched in a shell script, so I am wondering if I can check that the string does not equal /path/to/real/deal and not empty (since /path/to/real/deal is the default) and allow users to write to places they have permissions for. My impression of linux permissions is that it is tied to the application itself and cannot be conditionally approved, but I wonder if there is some bash fu or alternative method I can perform to get me my desired result. Using Ubuntu 10.04.4 LTS

• Boot records messed on dual boot (win7 and ubuntu) machine with SSD and HDD

  - by Michael

  i have a lenovo ideapad y570 with two hard drives: SSD and normal HDD both managed by RapidDrive and windows 7 pre-installed. First, i have shrunk my 500 GB HDD a little bit to make some place for a linux installation. Then i installed linux mint 12 to it, also installed grub onto the drive (dev/sdb). Installation programm has not allowed me to install grub on sda. Then i replaced linux mint with ubuntu 12.04 but installed grub onto the SSD (which is dev/sda and was the default-option). After that i could boot into my windows, only ubuntu worked. So i did a research, and tried: rewriting mbr of windows into sda1, reinstalling grub, replacing grub2 with grub-legacy, and now i think my partitions table are totally messed. Here is fdisk -l output: ubuntu@ubuntu:~$ sudo fdisk -l Disk /dev/sda: 64.0 GB, 64023257088 bytes 255 heads, 63 sectors/track, 7783 cylinders, total 125045424 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 * 2048 411647 204800 7 HPFS/NTFS/exFAT /dev/sda2 411648 1009430959 504509656 7 HPFS/NTFS/exFAT Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x5e5d1cc8 Device Boot Start End Blocks Id System /dev/sdb1 * 1979 884389887 442193954+ 12 Compaq diagnostics /dev/sdb2 884391934 976771071 46189569 5 Extended /dev/sdb5 884391936 937705471 26656768 83 Linux /dev/sdb6 937707520 967006207 14649344 83 Linux /dev/sdb7 967008256 976771071 4881408 82 Linux swap / Solaris I also cant mount any windows partitions to recover data. And when i open gparted, the whole sda-disk appears unallocated and it states "can not have a partition outside the disk!", also the end-sector address of /dev/sda2 confuses me. If i boot from the SSD, it throws some mbr error and wont boot, if i boot from the HDD, i only get the grub bash. How do i restore the partition tables? I can boot only from a live-cd at the machine. Thanks for any help.
