  • Tracing slow Java I/O in Solaris 10

    - by antispam
    We have a Java application which is significantly slower in Solaris 10 server than in Windows PC. We have profiled (-Xprof) the application and observed that UnixFileSystem.getBooleanAttributes0 method consumes about 40% CPU time with native calls. How can we follow our search to identify which is the cause of the slow behaviour? Thank you very much.

  • Physical button to run scripts on a windows machine?

    - by NoCarrier
    I frequently come in contact with people who absolutely cannot operate a PC, no matter how you train them. I need some sort of programmable physical button or remote control, where when they click it, it will execute a script on a windows machine. (and no, wiseguys, a mouse won't do) Does such a thing exist?

  • Benchmark virtual machines?

    - by evan
    I'm looking for a good way to benchmark the performance of Ubuntu machines (preferably from the command line - only care about harddrive speed, memory, and cpu - not graphics). Are there any programs that could also be used on Mac or Windows so I could compare the results against an Apple or PC Desktop? Ultimately I'd like to use these benchmarks to compare different virtual machine configurations (speeds on different hosts and different hardware to get practical idea of the differences between different setups a rigs). Thanks!

  • NTFS.SYS error at boot in Win XP

    - by petergrf
    I am using Windows XP and this morning it didn't boot, it showed an error on "Windows/system32/config/SYSTEM" so I connected the hd to another pc, rename that file and then copy the one in Windows/Repair. And now it shows the error cannot find or corrupted "ntfs.sys". I tried copying ntfs.sys from the windows installation cd but still get the same error, also tried "EXPAND :\i836\ntoskrnl.exe ( and ntkrnlpa.exe ) :\Windows\System32" but the error persist. What other fixes can I try?

  • RDPClip is not launching when I use Remote Desktop

    - by Ross
    When I'm using remote desktop to connect to my PC from my laptop(both running Windows 7 ultimate), RDPClip.exe never gets started. I can run it manually and copy/paste will work just fine, but I have no idea why it won't start automatically. I've done the usual of making sure the "Drives" checkbox is checked, but other than that I have no idea why it's mad.

  • Does this video card support sound?

    - by Macros
    Probably a rookie question but here goes...I am looking to buy a new video card for a few year old PC which will be used as a media centre. The card I am looking at is this one http://www.ebuyer.com/product/173708, with the main aim being to play blu-ray films. In the product description it states that the card has 7.1 audio channel support, does this mean it will play the sound from the blu-ray through the HDMI, or do I need a separate sound card?

  • Windows 7 boots with a blank screen with mouse cursor only.

    - by user2352
    My Windows 7 machine was powered down without logging out first. Now when booting the PC, Windows 7 does not completely start--instead it boots to an all-black screen with a mouse cursor that can be moved around. There are no icons, toolbars, etc. Ctrl+Alt+Del does not bring up the Task Manager. Booting to Safe Mode renders the same result.

  • Is it safe to swap SATA ports during hibernation?

    - by netvope
    I hibernated my Windows 7 desktop PC, replaced the SATA cables of my 2 hard drives (without paying attention to which ports they were connected), and resumed the system. Everything appeared normal and it entered the desktop with all the applications previously open before hibernation. However, after a few seconds, the screen became frozen and the system no longer responded to anything (mouse/keyboard/network ping). Does anyone have a definitive answer on whether changing SATA ports of the HDDs during hibernation would crash a Windows 7 system?

  • What is the bitrate of itunes streaming

    - by The Journeyman geek
    I've been using itunes streaming (in part cause its easy) to access my music collection between two windows PCs. I'm half certain it sounds kinda 'flat' so i'm wondering, what bitrate it uses, and format - it sounds fine off a PMP, and even better on a PC, so i assume i can tell the difference.

  • Creating a password-protected task in Windows 7

    - by Matthias
    I would like to configure a task like "child control software", so it would hibernate the pc at certain times. Is it possible to prevent modification (here: pausing) of a task through requiring the entering of the admin password to modify, EVEN THOUGH the currently-logged-in (and only) user is the admin account itself? (Do you know of any child control software that does NOT require an additional account yet is able to hibernate the system at certain times?) Thanks a lot!

  • Partitioning Windows 8.1 in order to have data partition first and system partitions at HDD end

    - by LivingSilver94
    How can I have recovery partition at the HDD end? My aim is to have data partition installed on fastest sectors of my hard drive, as I don't really care if restoring operations are slow... During Windows installation, when I create a partition, I get immediately created EFI and recovery ones just before the actual data partition. EFI position is good, I want my PC boot fast, but I want to move partitions I don't care about speed. I've also considered GParted, but I think I'm not able to use it :P

  • HDMI Disconnects after TV has been off for a while

    - by Adam Haile
    I have an EVGA NVidia GT 610 card in a media center PC running Windows 8 x64 When the TV has been turned off for a while and then turned back on, there will usually be no HDMI signal until I unplug the HDMI cable and plug it back in. Any ideas how what might be causing this or what I should check? I have the latest drivers from NVidia and the card recognizes the TV just fine. Also, my XBox 360 and PS3 work just fine and always show up.

  • i7 4770k or i7 4930k - Which for faster compile times? [on hold]

    - by Chumm
    I've looked up comparisons and found that single core performance seems to be better on i7 4770k, but has less cores that the i7 4930k. Would VS take advantage of extra cores when compiling, or would the difference be negible. I'm looking to buy the PC primarily for programming, so which would be better for visual studio? I already have the rest of my build ready, I just need to decide on this! :) thanks

  • Will any USB DVD reader work with Apple Mac's?

    - by Kev
    Following on from this question: Can Apple Macintosh computers boot from a USB volume? Can I use any USB 2.0 DVD drive to boot a Mac from? I had a look around my local PC World today and only the more expensive drives explicitly state on the packaging that they were Mac compatible. Is this just because these products have been through Apple's hardware approval/testing programme, or do Mac's have some special requirement?

  • Can I combine two LANs into one to get double speed?

    - by Salaam
    Hey guys, I have 2 LANs in my own PC & 2 Routers (TP-Link WR941N each) with 2 internet accounts (512Kbps each) connected to the same ISP signal & company using NanoStation 5 from ubnt. As you know the connections work separately by default! (I use Windows 7 64bit) Can I merge them to get double speed (download/upload simultaneously) using regedit or special software or any other method? I'd be much appreciated if u could help me doing that Best Regards, Salaam
