  • BSOD trying to migrate Windows XP from a physical to a virtual machine

    - by pauldoo
    I am attempting to migrate a Windows XP Home installation from a physical machine to a virtual machine. The physical machine has two hard disks; the first is 250GB containing the "C:", the second is 1TB containing "D:". I'd like to create a new virtual machine stored on the D:, which is a copy of the Windows XP Home installation that is currently on the C:. (This will leave the 250GB drive clear for me to install a fresh copy of Windows 7, and still be able to access the old XP installation if necessary.) The first method I tried was to follow the instructions here: http://www.virtualbox.org/wiki/Migrate_Windows I booted up from an Ubuntu Live CD in order to execute the Linux commands whilst the Windows system wasn't running. With this method the virtual machine would always blue screen on startup with a "STOP 0x0000007B" message. The instructions above say to try a "repair install" using the Windows XP disc. Unfortunately for me my XP disc is scratched and will not boot so I was unable to try a repair install. The second method I tried was to use "VMWare Converter Standalone Client". This tool executed without any errors, but again produced a virtual machine that blue screens on startup with the same "STOP" message. Are there any other methods to move the Windows XP installation into a virtual machine? I think next I will try some more manual process to create the cloned virtual machine. I think I will try installing a fresh copy of Windows XP to a virtual machine, then once that is booting OK I will ntfsclone the source C: partition over the top. Perhaps this will fix the booting problems if the issue is related to the MBR or partition table in some way.

  • Dual VGA monitors with Quadro FX 580?

    - by dentrasi
    I have a machine with a Quadro FX 580 card (DVI and two Displayport). Attached to it are two 19" Acer screens, which are both (annoyingly) VGA. The first one works perfectly, with a DVI-VGA adaptor. The second one doesn't work. It's got a VGA cable, which goes into a VGA-DVI converted, which then goes into a DVI-Displayport converter. Initally, I was getting 'Cable Unplugged' on the screen, and it couldn't be seen by Windows or the nVidia control panel. After swapping the VGA-DVI adaptor (which works perfectly on another machine), Windows can now see the monitor. The nVidia panel sees the model and native resolution, but I get a constant 'No Signal' error. Switching to the other Displayport makes no difference. I suspect that the card is seeing a DVI connection plugged into it (nVididaCP shows the monitor as having a DVI connection), and it only sending out a digital signal because of this. Does anyone know of a solution (other than trying to get a Displayport-VGA adaptor), or of a way to force the card to see it as VGA? Thanks, ~Dentrasi

  • Puppet's automatically generated certificates failing

    - by gparent
    I am running a default configuration of Puppet on Debian Squeeze 6.0.4. The server's FQDN is master.example.com. The client's FQDN is client.example.com. I am able to contact the puppet master and send a CSR. I sign it using puppetca -sa but the client will still not connect. Date of both machines is within 2 seconds of Tue Apr 3 20:59:00 UTC 2012 as I wrote this sentence.

  • Simple P2V help from Linux to Windows

    - by Ke
    Hi, I have two OS's installed on different drives in my PC. One linux (Centos 5.4) and one windows 7. Its getting tiresome to constantly have to stop and restart the PC when I want to use either OS. I would very much like to use Windows 7 as my host OS and access my linux OS from within Windows. However, im having trouble deciphering exactly how to do this (many of the articles seem confusing and a bit overkill) From what i have seen its possible to use VMWare converter to convert the physical linux image to a virtual image so that I can use it in windows. As im having problems understanding how this is done, I would really appreciate a step by step guide (for a newbie), or any simple tutorials that you can point me at. Some questions beforehand: 1) My linux image is around 80gb, do i need to take this into consideration? The linux drive is around 180gb in total. All my other drives are NTFS non writeable in linux (as I use them in windows and ntfs is dodgy in linux), so probably not possible to move the image over to my ntfs drives 2) Can I just zip the linux files up somehow and transfer it to windows to create the p2v? 3) Is it possible to do the P2V conversion while I am logged into windows. I can see the actual linux drive loaded in disk manager, but windows doesnt read linux file systems so im confused as to how to access the linux drive if this is possible. 4) Or will i need to do the whole p2v conversion inside linux? Cheers, any help is much appreciated Ke (a confused p2v newbie)

  • Long Gigabit Ethernet Run

    - by Timothy R. Butler
    I am trying to get an Gig-E network between two buildings that are approximately 260 ft. away. While some TRENDnet switches failed to be able to connect to each other over Cat 6 at that distance, two Netgear 5-port Gig-E switches do so just fine. However, it still fails after I put in place APC PNET1GB ethernet surge protectors at each end before the line connects to the respective switches. So I find myself wondering if I simply need to find a better surge protector that doesn't degrade the signal as much (if so, what kind would you recommend?) or if I should give up on copper and use fiber between the buildings. If I opt to go the latter route, I could really use some pointers. It looks like LC connectors are the most common, but I keep running into some others as well. A media converter on each end seems like the simplest solution, but perhaps a Gig-E switch with an SFP port would make more sense? Given a very limited budget, sticking with my existing copper seems best, but if it is bound to be a headache, a 100 meter fiber cable is something I think I can swing cost wise.

  • IE8 error with Certificate

    - by Jon B
    I have installed a certificate with multiple Common Names on a Red Hat server in the jks format. The web page can be accessed with Firefox and the certificate gets imported. However, IE8 gives the error "Internet Explorer cannot display the webpage". I added the cert with MMC and its properties shows "This certificate has an nonvalid digital signature.". Also the cert doesn't have the URL of the web page in it. The cert does have a valid signature in Firefox and the URL mismatch is ignored. How can I get IE8 to accept it. This cert is required for another Application (where it works fine) and cannot be changed except to change the format. I already have it in PKCS12, jks and pem formats.

  • store everything only once, smarter

    In the digital world a lot is stored multiple times. As a thought experiment or creative challenge I want you to think about making this more efficient and maybe reuse more. Think of the following cases: an mp3 track is downloaded multiple times, copied over various devices on website a login form is often rebuild many times, why not reuse more code? words themselves are used many times questions and answers are accidentally saved at many places in parallel images or photos often describe the same data (Eiffel tower, Golden gate, Taj Mahal) etc etc Are you aware of solutions? Or are you thinking about similar topics? Ideas? Blueprints? I'd love to hear from you!

  • Windows Vista claims wireless key is the wrong length

    - by humble coffee
    A family member of mine is house sitting and has been given the details of their wifi. The access point is an Airport Express, it has WEP encryption (I think) and they've been given a passphrase to use. I know it's a passphrase and not the encrypted key as it's an English word. The passphrase is 10 characters long. The problem is that Vista complains that it's not a valid key as it must be a 5 or 13 character non-hex key or a 10 or 26 character hex key. (From what I've read this suggests the encryption is WEP?) I've found a couple of suggested solutions, but I'm not actually at the house at the moment so I wanted to make sure I have a good chance of getting it to work when I'm there but have no internets to ask. Solution 1: Vista needs to be told explicitly what kind of encryption and key is being used. Specify in the connection settings that you are using WEP and that it is a "shared key". Solution2: Try converting the passphrase to hexadecimal using an ASCII-hex converter and entering that.

  • USB interface barcode scanners

    - by Nimbuz
    Not exactly a programming question, but close. I'll try my luck anyway. The keyboard wedge barcode scanner inserts the translation device between the reader and the keyboard. Data sent through a wedge appears as if it was typed into the computer, while the keyboard itself remains fully functional. Because a computer using a keyboard wedge can't tell the difference between data that is entered by a scanning device, or data that is entered by keyboard typing, a wedge can be used to easily add barcode reading capability to an existing computer without modifying software applications. I'd like to know if all USB interface barcode scanners automatically translate digital signals from a barcode reader into keyboard strokes for a applications just like wedge or is USB different from wedge? Many thanks

  • LabVIEW: converting numeric array to string array

    - by JaysonFix
    Using LabVIEW 2009, I have a VI that outputs an array of U64 integers. I'd like the user to be able to perform discrete selection from among the elements of this array. I'm thinking of accomplishing this by programmatically populating a Menu Ring (as shown at http://digital.ni.com/public.nsf/allkb/FB0409491FAB16FA86256D08004FCE7E). However, I apparently need to convert my array of U64 ints to an array of strings, as it is an array of strings that is used to populate the Menu Ring. My question: how can I convert the array of U64 ints to an array of strings?

  • How to "kill" background worker completely?

    - by Ken Hung
    Hi All, I am writing a windows application that runs a sequence of digital IO actions repeatedly. This sequence of actions starts when the user click a "START" button, and it is done by a background worker in backgroundWorker1_DoWork(). However, there are occasions when I get the "This backgroundworker is currently busy......." error message. I am thinking of implementing the following in the code, by using a while loop to "kill" the background worker before starting another sequence of action: if (backgroundWorker1.IsBusy == true) { backgroundWorker1.CancelAsync(); while (backgroundWorker1.IsBusy == true) { backgroundWorker1.CancelAsync(); } backgroundWorker1.Dispose(); } backgroundWorker1.RunWorkerAsync(); I think my main concern is, will the backgroundWorker1 be "killed" eventually? If it will, will it take a long time to complete it? Will this coding get me into an infinite loop?

  • How to efficiently track my geolocation during traveling using iPhone

    - by Peter Kruithof
    I'm going to travel through Thailand and I want to keep track of my location to geotag photos afterwards taken with a digital camera (iPhone's camera is not good enough). There are two things that are important here: I don't want to update manually I want the battery to last as long as possible, since the times I will be able to charge will be scarce I've thought about creating a web page that periodically sends my geolocation to a script that stores it in a database, but I don't know if GPS data is available in Mobile Safari. Second, I want the data I send to be as small as possible, and the frequency this is done s few as possible, because of the pricing of mobile data usage abroad. Any suggestions what would be a good solution here?

  • Getting 2560x1600 out of an ATI Radeon HD 4670 on Windows 7

    - by Alexey
    Greetings, I've got a Dell Studio XPS 1640 laptop (with an ATI Radeon HD 4670 graphics card) running Windows 7, and just bought a Dell 3007HPC 30-inch monitor for it. I'm trying to figure out how to get the full 2560x1600 experience out of this setup. Here's what I've done so far: Plug in using an HDMI cable and an HDMI--D-DVI converter on the monitor side. Open up Screen Resolution. Maximum supported setting is 1920x1080. Tried that (several times) - sometimes it doesn't work at all (blank screen); other times, it only shows the first 1280x800 pixels on the bigger screen. Tried using the Catalyst control center - played with various settings there, couldn't get the screen to show anything interesting. Tried using PowerStrip to set a custom resolution, again, no luck. Spoke to a Dell Preferred Custom Support guy for about an hour before giving up. He remote-accessed my computer, and told me that (1) The maximum supported resolution for XPS 1640 is 1920x1080, and (2) 'it seems to be working from where he sees it, must be a connection issue'. None of this has helped. Does anybody have ideas? Should I be using a different cable set up? Am I using Powerstrip wrong?

  • What is the underlying reason for not being able to put arrays of pointers in unsafe structs in C#?

    - by cons
    If one could put an array of pointers to child structs inside unsafe structs in C# like one could in C, constructing complex data structures without the overhead of having one object per node would be a lot easier and less of a time sink, as well as syntactically cleaner and much more readable. Is there a deep architectural reason why fixed arrays inside unsafe structs are only allowed to be composed of "value types" and not pointers? I assume only having explicitly named pointers inside structs must be a deliberate decision to weaken the language, but I can't find any documentation about why this is so, or the reasoning for not allowing pointer arrays inside structs, since I would assume the garbage collector shouldn't care what is going on in structs marked as unsafe. Digital Mars' D handles structs and pointers elegantly in comparison, and I'm missing not being able to rapidly develop succinct data structures; by making references abstract in C# a lot of power seems to have been removed from the language, even though pointers are still there at least in a marketing sense. Maybe I'm wrong to expect languages to become more powerful at representing complex data structures efficiently over time.

  • VMware Fusion won't boot my Boot Camp partition

    - by Sean
    I have a Boot Camp partition on my MacBook that I would ultimately like to convert to a VMware virtual machine image. I've installed VMware Fusion and tried to start up my Boot Camp install using the Boot Camp button on the initial welcome screen. It brings up the "VMware Fusion is preparing your Boot Camp partition to run as a virtual machine" dialog, but afterward it shows an error dialog with the following message: Boot Camp partition preprocessing failed. You may not be able to boot your Boot Camp partition as a virtual machine. It then tries to boot the new VM, but it blue screens during the boot process. The info on the blue screen doesn't provide much in the way of help though. Running chkdsk has no effect. After searching around, some people recommended using VMware's stand-alone converter utility from within Windows to create an image, but the utility said it couldn't create an image because my disk uses a GUID Partition Table (GPT). I'm wondering if this is why it can't boot my BC partition from Fusion. Has anyone else run into this and found a fix?

  • Java playback of 24 bit audio is incorrect

    - by Paul Hampson
    I am using the javax sound API to implement a simple console playback program based on http://www.jsresources.org/examples/AudioPlayer.html. Having tested it using a 24 bit ramp file (each sample is the last sample plus 1 over the full 24 bit range) it is evident that something odd is happening during playback. The recorded output is not the contents of the file (I have a digital loopback to verify this). It seems to be misinterpreting the samples in some way that causes the left channel to look like it is having some gain applied to it and the right channel looks like it is being attenuated. I have looked into whether the PAN and BALANCE controls need setting but these aren't available and I have checked the windows xp sound system settings. Any other form of playback of this ramp file is fine. If I do the same test with a 16bit file it performs correctly with no corruption of the stream. So does anyone have any idea why the Java Sound API is modifying my audio stream?

  • Does the Lenovo t60p vga port support an s-video signal?

    - by Matthijs Wessels
    I just bought a new television. The problem is it turns out it doesn't have a VGA port. It does have: s-video, component, hdmi and scart. My Lenovo t60p only has vga. If have search frantically for a solution and even though it seems I have sooo many options they are all dead ends. Or I keep ending up having to buy a 100 euro box to convert the signal. However, I found that some video cards support s-video through the vga port. It says look it up in your video cards documentation. I have a Lenovo t60p laptop with a ATI MOBILITY FireGl v5250. But I can't seem to get my hands on any documentation where this is supposed to be documented. I found this website: http://forum.notebookreview.com/showthread.php?t=179529&highlight=s-video There this guy says he thinks it's in the t60 but dropped in the t61, but suggests to the guy with the t60 that it won't work. I can't really conclude anything from that. Furthermore, I am not looking for the best of the best quality. So when I found this: *http://www.amazon.com/VideoSecu-Computor-Presentation-Converter-VGA2TV/dp/B000X3FAJU/ref=pd_cp_e_3_img I woudl be quite happy with this. Except that I don't think I can order it because I don't live in the US. Can anybody give me a definite answer, to whether the vga port of my lenovo t60p ati firegl v5250 supports s-video? So that I can just by a vga to s-video cable to achieve my goal.

  • Windows 7 blank dvi screen

    - by user99
    I've just upgraded to Windows 7 Ultimate 64 bit. I had an issue during installation; after setup rebooted instead of going to the 'Completing installation' screen I just got a blank screen. I eventually(!) figured out that this meant 'un-plug your second monitor to proceed'. When I did this, installation completed in a snap and everything runs fine. However, whenever I plug my second monitor into my PC, it gets no signal, the the primary monitor removes all windows. icons, the taskbar and the cursor just shows the desktop wallpaper. I'm running a GTS8800 512mb, with the latest drivers (197 IIRC). The monitors are identical, and both plug into DVI sockets on the graphics card, the only difference is I connect one using a straight DVI cable and the other using a VGA cable and a VGA-DVI converter. It's the DVI cabled one that has the issues (if I plug it in by itself it gets no signal). Everything was working fine before I upgraded to Windows 7 (I used to run XPSP2). Anyone have any ideas?

  • [jquery/javascript] Trigger function when mouse click inside textarea AND type stop typing...

    - by marc
    Welcome, In short, my website use BBcode system, and i want allow users to preview message without posting it. I'm using JQuery library. I need 3 actions. 1) When user click in textarea i want display DIV what will contain preview, i want animate opening. 2) When user typing, i want dynamical load parsed by PHP code to DIV. (i'm still thinking what will be best option... refresh every 2 seconds, or maybe we can detect and refresh after 1 second of inactivity [stop typing]) 3) When user click outside textarea i want close preview div with animation. For example the PHP parser will have patch /api/parser.php and variable by POST called $_POST['message']. Any idea my digital friends ?

  • Firewall for internal networks

    - by Cylindric
    I have a virtualised infrastructure here, with separated networks (some physically, some just by VLAN) for iSCSI traffic, VMware management traffic, production traffic, etc. The recommendations are of course to not allow access from the LAN to the iSCSI network for example, for obvious security and performance reasons, and same between DMZ/LAN, etc. The problem I have is that in reality, some services do need access across the networks from time to time: System monitoring server needs to see the ESX hosts and the SAN for SNMP VSphere guest console access needs direct access to the ESX host the VM is running on VMware Converter wants access to the ESX host the VM will be created on The SAN email notification system wants access to our mail server Rather than wildly opening up the entire network, I'd like to place a firewall spanning these networks, so I can allow just the access required For example: SAN SMTP Server for email Management SAN for monitoring via SNMP Management ESX for monitoring via SNMP Target Server ESX for VMConverter Can someone recommend a free firewall that will allow this kind of thing without too much low-level tinkering of config files? I've used products such as IPcop before, and it seems to be possible to achieve this using that product if I re-purpose their ideas of "WAN", "WLAN" (the red/green/orange/blue interfaces), but was wondering if there were any other accepted products for this sort of thing. Thanks.

    - by Maxood
    I'm an undergrad Computer Science student and studying online. There is a lot of self study, independent research and practice i have to do myself. I wonder how beneficial would it be to choose this subject combination in programming: Data Structures OOP Assembly Language & Computer Architecture Although i also have the option to take DLD (Digital Logic Design) or Data communication courses instead of Assembly Language. My interest lies in programming and i'm also working as a programmer at local software house. Can anyone give me some good advice and suggestions.

  • Preserve time stamp when shrinking an image

    - by Ckhrysze
    My digital camera takes pictures with a very high resolution, and I have a PIL script to shrink them to 800x600 (or 600x800). However, it would be nice for the resultant file to retain the original timestamp. I noticed in the docs that I can use a File object instead of a name in PIL's image save method, but I don't know if that will help or not. My code is basically name, ext = os.path.splitext(filename) # open an image file (.bmp,.jpg,.png,.gif) you have in the working folder image = Image.open(filename) width = 800 height = 600 w, h = image.size if h > w: width = 600 height = 800 name = name + ".jpg" shunken = image.resize((width, height), Image.ANTIALIAS) shunken.save(name) Thank you for any help you can give!
