  • How to preserve file attributes when one copies files in Windows?

    - by netvope
    On Linux, we can simply do: cp -pr directory How to do that in Windows? Can it be done in Windows Explorer? Any GUI tool suggestions? It would be the best if I can keep the NTFS permissions and creation/modification/access time. At a minimum, I need to preserve the modification date for the files and the directories. Windows Explorer's copy does not preserve the modification date for directories.

  • What are your favorite open source tools? (that are not very famous)

    - by sucuri
    I believe every system administrator is used to open source by now. From Apache to Firefox or Linux, everyone uses it at least a little bit. However, most open source developers are not good in marketing, so I know that there are hundreds of very good tools out there that very few people know. To fill this gap, share your favorite open source tool that you use in your day-to-day work that is not very famous. *I will post mine in the comments.

  • '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?

  • How can I identify a mystery tray icon in Windows 7?

    - by Mark
    A new icon has appeared in my tray in Windows 7 recently - a black square with a white A in it: It doesn't have any tooltip or right-click context menu so I haven't been able to identify which process it belongs to. I tried using the "Find Window's Process" tool in Process Explorer but that won't identify individual tray icons. Short of killing processes until it disappears, is there a good way to identify which process this icon belongs to?

  • ruby on rails server is intermittently slow

    - by Richard
    My rails installation was chugging along nicely. Last night we had to perform a hot-patch with was really a standard deploy of some exception code. Once capistrano finished the operation one of our admins discovered that there were two long running passenger processes. While we have deployed release over the past two weeks it would appear that these processes have been here and alive the whole time. Granted they could have been zombies or any other artifact and at this point we do not know what state they were in. Which leads me to the question: There are so many moving parts between the rails application and the OS/hardware that being a SME is probably no longer possible. So; how does a sysadmin perform root-cause analysis with any certainty? And: When do I just start rebooting servers?

  • Multiple pages per sheet (PDF)

    - by smihael
    I use the following commands pdf2ps input.pdf - | psnup -pA4 -4 >> output.ps ps2pdf output.ps output.pdf rm output.ps to merge multiple pages (in this case 4) from input file to one sheet in outupt file. How can I modify pipelining so that I won't have to use 2 commands, but just a single one liner? Is there any other commandline tool that would do the same and can work directly on pdf files?

  • Alternative to Softerra's LDAP Administrator?

    - by Michael Mao
    I am looking for an alternative to Softerra's LDAP Administrator, simply for the price is over-budget for a small team to test the LDAP credentials. So I really appreciate if someone can point me to some other alternatives for a Windows-based environment. We've got our Active Directory setup already, I only need a tool to confirm the access as a proof to customers. Sorry I am not a security guru, I am quite the opposite... Thanks for any suggestion in advance!

  • Storage sizing for virtual machines

    - by njo
    I am currently doing research to determine the consolidation ratio my company could expect should we start using a virtualization platform. I find myself continually running into a dead end when researching how to translate observed performance (weeks of perfmon data) to hdd array requirements for a virtualization server. I am familiar with the concept of IOPs, but they seem to be an overly simplistic measurement that fails to take into account cache, write combining, etc. Is there a seminal work on storage array performance analysis that I'm missing? This seems like an area where hearsay and 'black magic' have taken over for cold, hard fact.

  • Can a PCI Graphics card, and AGP be used together?

    - by Everyone
    The question pretty much says it all. I use an old 845GBV board ( to-date reliant upon the integrated graphics processor ). All slots on the board are unused. Lately I've been thinking in terms changing it to a dual monitor so that I can use one console for documentation/help/sample code/whatever, the other one to play with code. Assuming this board can handle a PCI GPU, can an AGP4x board coexist with a PCI GPU?

  • Extract structured data from many MS Word files

    - by Mark
    I have ~160 MS Word files that contain structured data. The data is formatted identically across all files and resides in a tabular format. I'd like to extract the data into a database, XML or just an aggregate table without opening each of the files independently. Is there a tool or method I can use to extract this data?
