  • How to debug high memory usage by registry?

    - by bkr
    I have a windows 2008 r2 server running ADFS2 and some web apps that is having issues with low memory. Digging around I found that the 5.5 GB were being used under Kernel Memory (paged). Further digging with Poolmon, I discovered that the majority of that (5GB+) was being used by CM - configuration manager. Also known as the registry. I'm really now sure how to tell why the registry is using so much memory however, or how to release it? Looking at the physical registry files they don't appear that large. EDIT #1 Using the powershell script @ http://jdhitsolutions.com/blog/2011/05/get-registry-size-and-age/ confirms what I saw looking at the physical registry files, that they're relatively small Computername : (removed) Status : OK CurrentSize : 67 MaximumSize : 2048 FreeSize : 1981 PercentFree : 96.728515625 Created : 4/1/2011 11:38:02 AM Age : 454.23:41:28.2540682

  • using ruby-debug with jruby-1.5.0

    - by brad
    Release notes say that ruby-debug is installed by default. I'm using rvm. In my rails app I figured something as simple as script/server --debugger would suffice, but it complains that the ruby-debug gem isn't installed, suggests using gem install ruby-debug, which of course doesn't work (building native extensions) and is contrary to the docs anyway. Just wondering if anyone's had any luck using the built in ruby-debug in jruby 1.5 and what one needs to do in order run jruby in debug mode

  • Server memory issues, and expected level of service from hosting company

    - by Greg
    I'm involved in maintaining an Ubuntu VPS which runs our django websites (nginx/apache/mod_wsgi) and we've been having some memory spikes which have either caused the database to die, or induced kernel panic when the memory management system can't find any killable processes. I'm working on fixing the memory spikes, but I'm wondering whether there's anything I can do to better deal with the problem if it occurs again. Are there any tools I could use to detect the memory spikes and then, say, kill the offending process and email the server admin to fix it up? Killing off one website so that the server can remain operational is certainly preferable to the whole thing falling over. Also, we were charged $600 for after-hours service because we had to get the hosting company to restart the server - is this standard practice among hosting companies? Another provider I work with provides a panel with which I can stop and start the server myself, and given that a restart was all that was needed, $600 seems mightily excessive. (That's NZD, it's around $445 USD)

  • Help needed for SOAPUI

    - by Kangkan
    I am trying to test my webservice using SOAPUI (the free version). For testing concurrency, I wished to fire concurrent threads from SOAPUI onto the service. But with the options, the thred count increases gradually (even in the burst mode). The machine where SOAPUI is installed is a WinXP machine. Can I actually do the concurrency testing? If so how? Please guide me.

  • Does the openssl command line do key strengthening?

    - by chotchki
    If I run the openssl command line in hmac mode (as below), is the key used for the hmac used directly or is it hashed before using it as the key? echo "foo" | openssl dgst -sha256 -binary -hmac "test" | openssl base64 Similarly, when encrypting a file with openssl (as below)is the pass phrase hashed with the salt? (If so how is it done? A pointer to the right source file would be even better.) openssl enc -salt

  • How can the subView detect that the mainView is rotating?

    - by wolverine
    I have a mainView. To this view, I am adding a view of the same size. When the mainView(the background) rotates, its being detected but the subview doesnt have any idea about being rotated. And its functions are not even being called. Even when the program launches too, if I am in landscape mode, its the same way. How can I make the subView know that the device is being rotated?

  • finding process bottlenecks rails/ruby

    - by Ben
    I just got started with rails, and when I testing in development mode, I see in the logs that my Mailer action is taking 1175ms. Is there anyway to find out what exactly is the slow step? Also, there is a line that says (View:2, DB:1). I assume the DB means number of database lookups, but what about the view?

  • C#: how to obtain the current clock speed of an Intel i-series CPU when TurboBoost is activated

    - by shifuimam
    I know that it's possible to get this information - Intel's own TurboBoost sidebar gadget appears to use an ActiveX control to determine the current clock speed of an i3/i5/i7 CPU when TurboBoost is active. However, I'm wanting to do this programmatically in C# - obtaining the CurrentClockSpeed value from WMI tops out at the set maximum clock speed of the CPU, so in TurboBoost mode, it doesn't report the current actual clock speed.

  • How to change the install path of my Linux Source tree?

    - by Sen
    I was trying to bring up my custom kernel. I did the following : make menuconfig && make modules && make modules_install && make install I would like to change the install PATH. How can i do that? I tried doing export INSTALL_PATH=<my custom path> But then it is only creating the vmlinux.bin(it is not creating the ramdisk image!!) But if i am not doing that, make install will automatically create the ramdisk image in the default /boot folder. How can i change that?? Thanks, Sen

  • NTFS write speed really slow (<15MB/s)

    - by Zulakis
    I got a new Seagate 4TB harddrive formatted with ntfs using parted /dev/sda > mklabel gpt > mkpart pri 1 -1 mkfs.ntfs /dev/sda1 When copying files or testing writespeed with dd, the max writespeed I can get is about 12MB/s. The harddrive should be capable of atleast 100MB/s. top shows high cpu usage for the mount.ntfs process. The system has a AMD dualcore. This is the output of parted /dev/sda unit s print: Model: ATA ST4000DM000-1F21 (scsi) Disk /dev/sda: 7814037168s Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 2048s 7814035455s 7814033408s pri The used kernel is 3.5.0-23-generic. The ntfs-3g versions I tried are ntfs-3g 2012.1.15AR.1 (ubuntu 12.04 default) and the newest version ntfs-3g 2013.1.13AR.2. When formatted with ext4 I get good write speeds with about 140MB/s. How can I fix the writespeed?

  • ubuntu Grub boot hangs on external usb drive

    - by schoetbi
    Hi, i just gave xubuntu another try and installed it ordinarily on a external usb harddisk. I have another harddisk installed inside the laptop that has Windows Xp on it. Now the problem: When I boot from the external drive the boot menu of Grub 2 shows up and i see all installed bootable partitions including windows. Now I select Xubuntu and wait. When the Xubuntu Logo shows up the boot process hangs. Now the funny thing. When the logo shows up I can unplug the usb drive and reconnect it real fast. Then the boot process will continue!!! Since I am a Linux newbie I would appreciate every hint that can solve this so that I can enjoy a smooth Linux boot:-) EDIT Grub version is: tobias@ubuntu:~$ grub-install -v grub-install (GRUB) 1.98+20100804-5ubuntu3 Kernel is: tobias@ubuntu:~$ uname -r 2.6.35-23-generic Xubuntu is 9.10 Thanks

  • Performing full screen grab in windows

    - by Steven Lu
    I am working an idea that involves getting a full capture of the screen including windows and apps, analyzing it, and then drawing items back onto the screen, as an overlay. I want to learn image processing techniques and I could get lots of data to work with if I can directly access the Windows screen. I could use this to build automation tools the likes of which have never been seen before. More on that later. I have full screen capture working for the most part. HWND hwind = GetDesktopWindow(); HDC hdc = GetDC(hwind); int resx = GetSystemMetrics(SM_CXSCREEN); int resy = GetSystemMetrics(SM_CYSCREEN); int BitsPerPixel = GetDeviceCaps(hdc,BITSPIXEL); HDC hdc2 = CreateCompatibleDC(hdc); BITMAPINFO info; info.bmiHeader.biSize = sizeof(BITMAPINFOHEADER); info.bmiHeader.biWidth = resx; info.bmiHeader.biHeight = resy; info.bmiHeader.biPlanes = 1; info.bmiHeader.biBitCount = BitsPerPixel; info.bmiHeader.biCompression = BI_RGB; void *data; hbitmap = CreateDIBSection(hdc2,&info,DIB_RGB_COLORS,(void**)&data,0,0); SelectObject(hdc2,hbitmap); Once this is done, I can call this repeatedly: BitBlt(hdc2,0,0,resx,resy,hdc,0,0,SRCCOPY); The cleanup code (I have no idea if this is correct): DeleteObject(hbitmap); ReleaseDC(hwind,hdc); if (hdc2) { DeleteDC(hdc2); } Every time BitBlt is called it grabs the screen and saves it in memory I can access thru data. Performance is somewhat satisfactory. BitBlt executes in 50 milliseconds (sometimes as low as 33ms) at 1920x1200x32. What surprises me is that when I switch display mode to 16 bit, 1920x1200x16, either through my graphics settings beforehand, or by using ChangeDisplaySettings, I get a massively improved screen grab time between 1ms and 2ms, which cannot be explained by the factor of two reduction in bit-depth. Using CreateDIBSection (as above) offers a significant speed up when in 16-bit mode, compared to if I set up with CreateCompatibleBitmap (6-7ms/f). Does anybody know why dropping to 16bit causes such a speed increase? Is there any hope for me to grab 32bit at such speeds? if not for the color depth, but for not forcing a change of screen buffer modes and the awful flickering.

  • How do I get TextMate style quotes in Emacs?

    - by pdcawley
    In textmate, when there's a current selection, I hit the " key and the selection gets surrounded by quotes. The same thing happens with other balanced characters like (, {, [ and '. Am I missing something obvious in Emacs configuration that would enable similar behaviour when using transient mark mode, or do I need to break out elisp and write something?

In php, http://php.net/manual/en/function.ftp-fget.php this function allows arbitay starting point: bool ftp_fget ( resource $ftp_stream , resource $handle , string $remote_file , int $mode [, int $resumepos = 0 ] ) however it does not allow me to set "how many bytes" i want to download.

  • Visual Basic 9 with Visual Studio 2010

    - by jaraics
    I'm working on a project started in VB9 (VS 2008) and now I've migrated to VS2010 (VB10) but on the production server the IDE is still VS 2008. On my developement enviroment the code compiles fine, but sometimes, - let's say - I forget an _ at the end of the line which causes the VB9 compiler to throw an error. So the question is, how could I build a project with the VS 2010 IDE but VB9 compiler? Or to force the VB10 compiler into VB9 mode?

  • Where to store application global variable?

    - by Shawn Mclean
    I'm using silverlight, project structure is similiar to any other .net app. I have a map control that I would like to store what mode it is in (either road or aerial) so that other controls can access this. Where do I put this enum variable, I plan to use 2 way binding on it so both are updated when either changes. Thanks.
