  • How do I preserve ownership permissions when copying to an external volume?

    - by Yitzchak
    When I upgrade or reinstall linux I backup my home folder by running sudo cp -pr /home/users/yitzchak /media/externalHDD/backups. When I do this I get errors saying that permissions could not be preserved and when I copy the folder back onto my local disk I see that ownership has been changed to root and I have to chown all of them back, which has to be done manually piecemeal because not all files have the same group. Is there any way around that?

  • xmonad + urxvt issue: text disappears after resizing

    - by user1212010
    I'm using Arch Linux + xmonad + urxvt bundle and trying to resolve the conflict between xmonad and urxvt. Better to explain with shots: Firstly, open the terminal and get some full-length output. Secondly, create another window, which squeezes the first. And, finally, close it to find out that half of the output disappeared. Sometimes it behaves correctly, sometimes not. Tried to find out why, but failed. Many thx in advance!

  • Convert Chinese character .wav song into .mp3 or .wma on English OS

    - by Jack
    I have bunch of Chinese .wav files on my hard disk that I'm trying to convert into .mp3 with Audacity but it appear that Audacity can not read Chinese character songs but the .wav file display correctly on my 32 bits Win7 Ultimate(English) pc. I have to rename these Chinese character songs into English file name in order to convert them. Does anyone know if there is any software (prefer open source) that will take Chinese character file name(.wav) and convert it into .mp3 without renaming the file?

  • 'No volume found' on Windows 7 VM (VHD), can I get anything back?

    - by duka34
    The worst possible situation... Despite my vigilence doing backups, and trying to keep my PC secure, one of my VMs disk seems to be wiped out. Using the VHD tool from R1Soft (HyperV VHD Explorer), when I attach the VHD, it says no volumes found so it looks like something wiped out the VHD (which it still its original size). It seems that something has sneaked through whatever security I have/had and has wreaked havoc. Can I recover anything from this?

  • Is it possible to run multiple mongod instances on a single set of database files

    - by 9point6
    We have large multi-gigabyte data sets on which we run very complex queries, for example { $or: [ { id: 30000001, ... }, { id: 30000005, ... }, ..., { id: 30001005, ... } ] } It seems that CPU is actually a bottleneck at this point, so I'd be advantageous to be able to run multiple mongod instances on the same set of database files. We've considered using replica sets to this end, but would prefer to not require the extra disk space simply for CPU reasons.

  • Booting a virtual os on a physical environment

    - by Nrew
    Is there an application that allows you to add a virtualized version of your operating system into the mbr? By virtualized, I mean that if you boot this one, any changes made in it will not be committed to the disk. Just like how deepfreeze, returnil, and shadow user works. Is it possible to do that? Because the applications mentioned above requires you to reboot if you want that changes will not be retained.

  • iSCSI NAS supporting VMware Esxi 5.1 servers in a software development environment

    - by BigTFromAZ
    I would like to build (or purchase) the smallest, quietest most energy efficient servers that I can for a low demand environment. These would only have a small disk for guest swap files, a CPU (XEON preferred), 32 Gb of memory and minimal graphics. The virtual machines need to be up but demand will be quite low. Any thought on case, format processors, fans, motherboard, et al? Small, quiet and lots of RAM are the operative words here.

  • How can I create an Computer Icon on Windows 8 Server Beta's Desktop?

    - by bernd_k
    For some bad reason Microsoft decided to remove all standard desktop icons besides the Recyle bin. It is easy to create shortcuts to each single disk using create shortcut method. But I would like to have the computer icon too. I guess there will be an increased demand to create useful shortcuts on Windows 8 Servers Desktop, because the metro surface 'on the backside of your screen' is just impractical.

  • Create text file named after a cell containing other cell data

    - by user143041
    I tried using the code below for the Excel program on my `Mac Mini using the OS X Version 10.7.2 and it keeps saying Error due to file name / path: (The Excel file I am creating is going to be a template with my formulas and macros installed which will be used over and over). Sub CreateFile() Do While Not IsEmpty(ActiveCell.Offset(0, 1)) MyFile = ActiveCell.Value & ".txt" fnum = FreeFile() Open MyFile For Output As fnum Print #fnum, ActiveCell.Offset(0, 1) & " " & ActiveCell.Offset(0, 2) Close #fnum ActiveCell.Offset(1, 0).Select Loop End Sub What Im trying to do: 1st Objective I would like to have the following data to be used to create a text file. A:A is what I need the name of the file to be. B:2 is the content I need in the text file. So, A2 - "repair-video-game-Glassboro-NJ-08028.txt" is the file name and B2 to be the content in the file. Next, A3 is the file name and B3 is the content for the file, etc. ONCE the content reads what is in cell A16 and B16 (length will vary), the file creation should stop, if not then I can delete the additional files created. This sheet will never change. Is there a way to establish the excel macro to always go to this sheet instead of have to select it with the mouse to identify the starting point? 2nd Objective I would like to have the following data to be used to create a text file. A:1 is what I need the name of the file to be. B:B is the content I want in the file. So, A2 - is the file name "geo-sitemap.xml" and B:B to be the content in the file (ignore the .xml file extension in the photo). ONCE the content cell reads what is in cell "B16" (length will vary), the file creation should stop, if not then I can adjust the cells that have need content (formulated content you see in the image is preset for 500 rows). This sheet will never change. Is there a way to establish the excel macro to always go to this sheet instead of have to select it with the mouse to identify the starting point? I can Provide the content in the cells that are filled in by excel formulas that are not not to be included in the .txt files. It is ok if it is not possible. I can delete the extra cells that are not populated (based on the data sheet). Please let me know if you need any more additional information or clarity and I will be happy to provide it.

  • Setup wiped Polycom phone without SIP server

    - by Justin
    I'm troubleshooting a Polycom SoundPoint IP 550. I have wiped the hard disk of the phone (via a menu option) and now it's stuck in a reboot cycle. Apparently the only way to setup the firmware of the phone is to use a boot server. Does anyone know another way to setup the phone/firmware?

  • How big are most production databases?

    - by TheLQ
    Seeing some posts that say 10 million rows in a table is nothing made me wonder: Just how big are most production databases? I'm not talking about physical disk size of the database (saying 60 GB tells me nothing), I'm wondering how many rows. Personally the largest DB I've ever worked with was a test DB of a production system with 10 million rows. But I've seen people brag about DB's in the billions of rows.

  • Postfix - How to process incoming emails?

    - by Borivojevic
    Hello Does anybody know how to process incoming emails for virtual mailboxes in postfix? I am building web application where users add new content by sending emails to application. Email address used for each user is custom (eg. [email protected]) and it is dynamically created as a Postfix virtual mailbox. User needs to be able to send email to his custom mailbox address ([email protected]) and i want to process each incoming email, parse it's contents and populate my database with data from email. I tried using Postfix After Queue filter but what i really wont is to process emails once they are saved in users virtual mailbox folder.

  • Can't log into Windows XP

    - by lamcro
    Immediately after choosing an account, and starting to log in, it shows the logging out message and goes back to the account selection display. This even happened in safe mode with the administrator's account. So I can't log in. I'll be using a Linux Live CD to extract the laptop's data. Could this be a virus or a hard disk problem? And what should I do?

  • Advise about quick/full format

    - by ile
    Is it virus-safe to do quick format of hard drive? I want to format disk that was infected and install windows 7 on it, but I am not sure if Quick Format is secure enough. I am aware that it does not delete data but pointers to it, so I wonder if it is possible that virus activates from that data? Thanks

  • Is data=journal on a separate device on Ext4 as good as using a RAID controller with battery backed cache for file system consistency?

    - by Jeff Strunk
    It seems to me that data=journal prevents file system inconsistency in the case of power failure. Using it with a dedicated journal device mitigates the performance penalty of writing the data twice. A power outage would still lose the data that is currently being written to the journal, but the file system on disk would always be consistent. If that amount of loss is acceptable, is a RAID controller with battery backed cache really worthwhile?

  • Can't use Bootcamp partition for Windows 8 installation

    - by Hedge
    I'm trying to install Windows 8 with Bootcamp on my Macbook Pro. Sadly it won't let me get past the disk partition choice (even after formatting the Bootcamp-drive). It says: Windows can't be installed on this storage device. The chosen harddisk contains a MBR-partition-table. Windows can only be installed on GPT-harddisks on EFI-systems. freely translated What is going wrong here? Here's a photo:

    - by AridDecay
    I'm trying to find a place where I can download both Vista Home Premium and Windows 7 OEM Iso's. I own both, and my hard drive died in my Vista computer, so I ran out, bought another one and now need to re-install my OS. However, the computer came with it, and didn't come with a disk (Thanks Acer!) So, is there a place I can download an ISO of my Windows that ISN'T illegaly activated? I can't find any torrents that are legitimate. Thanks in advance!

  • Accountability in a cloud infrastructure (Amazon, etc)

    - by WinkyWolly
    I was curious how companies such as Amazon would handle some sort of investigation that needed to look into data potentially stored on one of their on-demand nodes. What typically happens to data in an environment like this after the VM is destroyed (literally what happens on the disk / FS)? Would it actually be possible to recover data from a destroyed node? Just a curiosity :)

  • Amazon S3 Iterating Through Multi-Page Results. (withMarker)

    - by Jitu
    Trying to iterate through AmazonS3 that has around 5000+ keys stored in the bucket, used sample code based on provided link on Amazon Developer Guide http://docs.amazonwebservices.com/AmazonS3/latest/dev/ListingObjectKeysUsingNetSDK.html Issue is iteration fails when NexMarker is passed which has length of more than 128 string characters, which seems unusal as withMarker accepts string as parameter and there is no documentation on limit to withMarker. request.Marker = response.NextMarker; Has anyone faced similar issue. Thanks in advance.
