  • Proper way to re-image Windows 7?

    - by Alec
    I had a driver completely fail on me so I have to restore my computer from a system image backup. I used an installation DVD to run the Re-Image utility on there, but after 8 hours of "preparing the image" to be restored, it began restoring to my hard drive. After 12 hours there, it was 5-8% complete. I figured I must have done something wrong or it started doing something wrong. So I installed a fresh copy of Win-7 and ran the utility from there. It's going at the same snail's pace. I still think I must be doing something incorrectly - I don't see how it could possibly take so long, I could probably manually flip the on my hard drive and be done before that utility. Am I doing this correctly or is there something else I should be doing? Edit: In case my hardware is relevant: Win 7 64 bit Core i7 8 GB Ram 640GB Internal 1TB External connected via eSATA I had approximately 400GB of data on my computer before it crashed.

  • Installing Sharepoint 2007 on Windows Server 2008 R2

    - by ronischuetz
    we are using in our lab a clean installation of Windows Server 2008 R2 which is running as Hyper-V instance. Today we wanted to install a clean installation of Sharepoint 2007 with SP1 on this machine and we explorer an error that we are not able to install it. The setup is comes up with an error which is described here: http://support.microsoft.com/kb/962935 but this is not our szenario. A printscreen of this message can be found here: http://www.ronischuetz.com/images/SP_2007SP1_Inst_Error.png @Microsoft, my personal point of view is that it cannot be that we need to install first 2008, then Sharepoint 2007 with SP1, then SP2 and upgrade to 2008 R2. Nobody is going be happy with this solution and I hope we find a fast way how customers can install Sharepoint direclty on 2008 R2. Anyway, thanks in advance for any further information how we should go on with this issue. The issue is listed here: http://social.msdn.microsoft.com/Forums/en-US/sharepointadmin/thread/91a6be50-9009-43c8-a37c-66cfb83d738f

  • how insecure is my short password really?

    - by rika-uehara
    Using systems like TrueCrypt, when I have to define a new password I am often informed that using a short password is insecure and "very easy" to break by brute-force. I always use passwords of 8 characters in length, which are not based on dictionary words, which consists of characters from the set A-Z, a-z, 0-9 I.e. I use password like sDvE98f1 How easy is it to crack such a password by brute-force? I.e. how fast. I know it heavily depends on the hardware but maybe someone could give me an estimate how long it would take to do this on a dual core with 2GHZ or whatever to have a frame of reference for the hardware. To briute-force attack such a password one needs not only to cycle through all combinations but also try to de-crypt with each guessed password which also needs some time. Also, is there some software to brute-force hack truecrypt because I want to try to brute-force crack my own passsword to see how long it takes if it is really that "very easy".

  • What is the best way to test using grails using IDEA?

    - by egervari
    I am seriously having a very non-pleasant time testing using Grails. I will describe my experience, and I'd like to know if there's a better way. The first problem I have with testing is that Grails doesn't give immediate feedback to the developer when .save() fails inside of an integration test. So let's say you have a domain class with 12 fields, and 1 of them is violating a constraint and you don't know it when you create the instance... it just doesn't save. Naturally, the test code afterward is going to fail. This is most troublesome because the thingy under test is probably fine... and the real risk and pain is the setup code for the test itself. So, I've tried to develop the habit of using .save(failOnError: true) to avoid this problem, but that's not something that can be easily enforced by everyone working on the project... and it's kind of bloaty. It'd be nice to turn this on for code that is running as part of a unit test automatically. Integration Tests run slow. I cannot understand how 1 integration test that saves 1 object takes 15-20 seconds to run. With some careful test planning, I've been able to get 1000 tests talking to an actual database and doing dbunit dumps after every test to happen in about the same time! This is dumb. It is hard to run all the unit tests and not integration tests in IDEA. Integration tests are a massive pain. Idea actually shows a GREEN BAR when integration tests fail. The output given by grails indicates that something failed, but it doesn't say what it was. It says to look in the test reports... which forces the developer to launch up their file system to hunt the stupid html file down. What a pain. Then once you got the html file and click to the failing test, it'll tell you a line number. Since these reports are not in the IDE, you can't just click the stack trace to go to that line of code... you gotta go back and find it yourself. ARGGH!@!@! Maybe people put up with this, but I refuse. Testing should not be this painful. It should be fast and painless, or people won't do it. Please help. What is the solution? Rails instead of Grails? Something else entirely? I love the Grails framework, but they never demo their testing for a reason. They have a snazzy framework, but the testing is painful. After having used Scala for the last 1.5 months, and being totally spoiled by ScalaTest... I can't go back to this.

  • Tiny linux box with 2xGbLAN, WLAN and 10MB/s AES throughput?

    - by Nakedible
    I'd like to find a small linux box with the following specifications: Small (mini-ITX size is OK) Fanless Runs Debian At least two gigabit network interfaces WLAN that supports "host ap" with hostapd + mac80211 in AP mode Can encrypt AES at least 10 megabytes per second Total cost $300 or less Solutions from multiple parts also accepted - I can buy an external network card etc. and build the box myself if the components are available. If you don't know about the "host ap" thing, just suggest your solution, I'll find out if I can get that resolved. If I can't get all that, I can possibly skip the "runs Debian" part, and I can definitely skip the hostapd part if the box can be a wireless access point with multiple ESSIDs out of the box. Something like Asus RT-N16 is close - doesn't run Debian easily, and probably doesn't encrypt AES fast enough. Something like Zotac ZBOX HD-ID11 is also close - no idea which WLAN card it has and it lacks second gigabit interface, but otherwise nice.

  • MSDCS zone missing

    - by hyp
    I seem to have an issue with our AD/DNS, the structure looks like: but the BPA gives me an error: Issue: The Active Directory integrated DNS zone _msdcs.<domain> was not found. Impact: DNS queries for the Active Directory integrated zone _msdcs.<domain> might fail. Resolution: Restore the Active Directory integrated DNS zone _msdcs.<domain> Now we've got 4 DC's in total: 2 running Server 2008 R2, 2 running Server 2003. The older ones will be retired sometime this year. Actually everything seems to be working ok (if something isn't then we don't know about it), we've got quite a few .NET applications authenticating against AD, no DNS issues from what I can tell and various bits on the network point to all 4 controllers. Furthermore a dcdiag /dnsall comes up with all passes. Is this something I should be worried about?

  • ODBC Connection Pooling

    - by beansy
    I have inherited a suite of .Net c# applications from a developer which talk to an Informix database on a unix server. Instead of using the usual practices for managing the database connections (disposable pattern / "open late / close early"), the code seems to open one ODBC connection when each app loads and doesn't close it. Connection pooling is turned via the ODBC administrator. Is there any way of seeing how many ODBC connections are open? What is the effect of turning off connection pooling? Am I right in thinking the .NET framework will use connection pooling anyway?

  • Restore default ownership in CentOS after terrible chown

    - by tgm
    Is there any way to restore the default ownership of a CentOS filesystem after an accidental chown -R user:group /* ? Before I go and reinstall, I thought I'd ask and perhaps save some time. I'm in the process of setting up a new dev machine (thankfully not prod) and typed too fast or missed the . key or something. I tried to cancel as soon as I caught it but all my /bin /boot /dev etc had already been changed. Is there hope, or just reinstall and be happy it wasn't a production machine?

  • Git pull with unstaged changes

    - by Peter
    Attempting a git pull when you have unstaged changes will fail, saying you can commit or stash then. I suppose a workaround is to git stash, git pull, then git stash pop. However, is there an alternative way to do this? I would like to forcefully git pull if there are unstaged changes, but only if the files being brought down do not override the modified files? AKA. if I have a repo with the files "derp1", "derp2", "derp3" and modify "derp1" locally, a git pull will bring down and overwrite everything except the "derp1" file. I assume a git stash + pull + stash pop achieves this already? And is there a better way? I suppose this could also work differently if it occurs on a submodule.

  • Error When Loading Images on Local Host Test Server

    - by ke4ktz
    I have a peculiar problem that I just can't seem to find an explanation. I'm working on an AngularJS site for our family and am integrating data from various web services. Currently I am working on the photos section which will integrate in photos from our Flickr account. I have a main page which lists the various photo sets and displays the set's primary photo along with the title. (Note: I'm using the Flickr 'extras' parameter to return the primary photo's URL in the API calls.) <div data-ng-repeat="p in vm.photoSets"> <a ng-href="#/photos/{{p.id}}"> <img ng-src="{{p.primary_photo_extras.url_s}}"></img> </a> <h4>{{p.title._content}}</h4> </div> When clicking on the photo, the routing will display a page with a list of all the photos from that set, showing the image and the title. <div data-ng-repeat="p in vm.photoSetData.photo"> <a ng-href="#/photos/{{vm.photoSetId}}/{{p.id}}" <img ng-src="{{p.url_s}}"></img> </a> <h4>{{p.title}}</h4> </div> Now, here's where the problem is occuring. When I upload the code to my public website on my hosting provider, everything works just fine. Both pages display their respective photos. However, when I attempt to run the site on my local system, either in MAMP or NodeJS (using http-server), the second page gives me an error for each image: Error: [$interpolate:interr] Can't interpolate: {{p.url_s}} Error: [$sce:insecurl] Blocked loading resource from url not allowed by $sceDelegate policy.

In fact, the image title does display! I've tested it with Firefox, Safari and Chrome...all three browsers fail. I cannot find any explanation as to why it would work remotely but fail locally. Also, the images show up on the first page, but not on the second, even though one of the images on the second page is the same image URL as on the first page. Even going directly to the second page, bypassing the first page, still fails. Any ideas on how to fix this? It would be nice to test locally without having to upload to the server each time I make a change. Update: I have shut off the $sce security to see if that was causing the issue. Although it resulted in turning the error off, the files still don't load on the local test server. I have used the developer tools' network monitor and it doesn't even show an attempt to retrieve the files. AngularJS appears to shut down the retrieval, although the correct path shows up in the DOM.

  • Why do C compilers prepend underscores to external names?

    - by Michael Burr
    I've been working in C for so long that the fact that compilers typically add an underscore to the start of an extern is just understood... However, another SO question today got me wondering about the real reason why the underscore is added. A wikipedia article claims that a reason is: It was common practice for C compilers to prepend a leading underscore to all external scope program identifiers to avert clashes with contributions from runtime language support I think there's at least a kernel of truth to this, but also it seems to no really answer the question, since if the underscore is added to all externs it won't help much with preventing clashes. Does anyone have good information on the rationale for the leading underscore? Is the added underscore part of the reason that the Unix creat() system call doesn't end with an 'e'? I've heard that early linkers on some platforms had a limit of 6 characters for names. If that's the case, then prepending an underscore to external names would seem to be a downright crazy idea (now I only have 5 characters to play with...).

  • FTP Issue when connecting to a debian machine from windows

    - by erin c
    I have a .net application which copies bunch of files to a specific FTP folder on a debian machine on periodical basis, ftp folder has 755 mod, owner of the directory is the ftp username that I authenticate in .net application. So far I tested this application with bunch of debian boxes, my initial attempts generally fail with following message if I try it with a debian machine that I haven't tried it before: "remote server returned an error 550 File unavailable" When I see this error, I log onto another debian machine on my network, and I try FTP'ing the debian box that returns the error message from command line. I generally "put" a very small file to the folder in question, right after that windows application starts copying files successfully via FTP. It is as if my command line ftp operation fixes the problem and makes debian compatible with my .net application. I checked permissions before and after the problem, it doesn't look like what I did changed anything, I am at loss understanding why this problem occurs and why it is fixed with my silly hack. Can anybody tell me where to look at next to fix this extremely annoying issue?

  • Input not cleared.

    - by SoulBeaver
    As the question says, for some reason my program is not flushing the input or using my variables in ways that I cannot identify at the moment. This is for a homework project that I've gone beyond what I had to do for it, now I just want the program to actually work :P Details to make the finding easier: The program executes flawlessly on the first run through. All throws work, only the proper values( n 0 ) are accepted and turned into binary. As soon as I enter my terminate input, the program goes into a loop and only asks for the termiante again like so: When I run this program on Netbeans on my Linux Laptop, the program crashes after I input the terminate value. On Visual C++ on Windows it goes into the loop like just described. In the code I have tried to clear every stream and initialze every variable new as the program restarts, but to no avail. I just can't see my mistake. I believe the error to lie in either the main function: int main( void ) { vector<int> store; int terminate = 1; do { int num = 0; string input = ""; if( cin.fail() ) { cin.clear(); cin.ignore( numeric_limits<streamsize>::max(), '\n' ); } cout << "Please enter a natural number." << endl; readLine( input, num ); cout << "\nThank you. Number is being processed..." << endl; workNum( num, store ); line; cout << "Go again? 0 to terminate." << endl; cin >> terminate // No checking yet, just want it to work! cin.clear(); }while( terminate ); cin.get(); return 0; } or in the function that reads the number: void readLine( string &input, int &num ) { int buf = 1; stringstream ss; vec_sz size; if( ss.fail() ) { ss.clear(); ss.ignore( numeric_limits<streamsize>::max(), '\n' ); } if( getline( cin, input ) ) { size = input.size(); for( int loop = 0; loop < size; ++loop ) if( isalpha( input[loop] ) ) throw domain_error( "Invalid Input." ); ss << input; ss >> buf; if( buf <= 0 ) throw domain_error( "Invalid Input." ); num = buf; ss.clear(); } }

  • Using string.Format for simple things?

    - by Gerrie Schenck
    In my early .Net programming days, I used string.Format() only for complex string concatenations, for example to compile strings as Problem with customer order 234 of date 2/2/2002 and payment id 55543. But now I use string.Format for almost every string concatenation I have to do, also simple ones such as prefixing a string with something. Console.WriteLine(string.Format("\t\t{0}", myString)); Is there any possible overhead on this? Maybe I should use the regular + operator to do these simple operations? What's your opinion on this?

  • What programs should I write to truly experience this fancy new language ?

    - by privatehuff
    Tried Scheme at one point, just built up half of a "math" and "string" library before getting bored... Similar experience with Java, but stopped early because I was appalled at the lack of operator overloading. When you try out a new language, is there a program/game/function/exercise/problem that you use to get into the hot meaty center and really EXPERIENCE the language? I've been wanted to try Python, Ruby, some lisps, etc but can't seem to find any meaningful work to do with them, or any reason to use them for anything over languages I already know. Sorry this is a discussion, but you are EXACTLY the people I want to get input from on this

  • Arch linux ati graphics crash after grub install

    - by Jay
    Ok, so I've had an arch linux w/ gnome 3 installed for a while now. And a while ago I installed ubuntu as another partition, I think to fix an issue that cause arch to fail. So, it was all working fine, but then I went and reinstalled grub 1 on the arch partition; Ubuntu had overwritten it on the install. Then when I tried to boot into arch it booted, but the graphics wasn't working correctly: gdm wouldn't even show, and there were weird colors instead. So, I uninstalled xf86-video-ati and then installed xf86-video-vesa. That made gdm run in fallback mode and I was able to boot to gnome 3 fallback mode (or whatever it's called). But I can't seem to get the graphics working correctly.

  • Generate or update a PDF to include an encrypted, hidden watermark?

    - by Dave Jarvis
    Background Using LaTeX to write a book. When a user purchases the book, the PDF will be generated automatically. Problem The PDF should have a watermark that includes the person's name and contact information. Question What software meets the following criteria: Applies encrypted, invisible watermarks to a PDF Open Source Platform independent (Linux, Windows) Fast (marks a 200 page PDF in under 1 second) Batch processing (exclusively command-line driven) Collusion-attack resistant Non-fragile (e.g., PDF - EPS - PDF still contains the watermark) Well documented (shows example usages) Ideas & Resources Some thoughts and findings: Natural language processing (NLP) watermarks. Apply steganography on a randomly selected image. http://openstego.sourceforge.net/cmdline.html The problem with NLP is that grammatical errors can be introduced. The problem with steganography is that the images are sourced from an image cache, and so recreating that cache with watermarked images will impart a delay when generating the PDF (I could just delete one image from the cache, but that's not an elegant solution). Thank you!

  • Can KVM CPU assignment count differ from physical hosts CPU count?

    - by javano
    I have read this question. I knew already that I could for example, have a quad core machine with four guests each having two vCPUs. As they don't all be require 100% CPU usage all the time, the scheduler would handle this for me. My question is about how this relates to a fail-over or migration situation; If host1 has two dual-core CPUs, and I assign guest1 four vCPUs (so it accessed all four physical cores), what will happen if I try and migrate it to host2 which only has one dual-core CPU? Can qemu-kvm emulate more vCPUs than there are physical? Or would I have to shut down the virtual machine, change the CPU assignment, migrate it, and then boot it back up (so no live migration)? Many thanks.

  • Benchmarks relevant for a Visual Studio .Net development workstation

    - by user30715
    I am developing a system with Windows 7-64, Visual Studio and Sharepoint on a virtual workstation on some kind of VMWare server. The system is painfully slow, with VS lagging behind when entering code, Intellisense lagging, opening and saving files takes ages when compared to a normal budget laptop. As far as I can see the virtual machine has OK specs and does not seem to be swapping etc., and the IT dept also says that they can't see anything wrong when they're monitoring the system. As long as the problem is not well-documented, the IT dept and management does not want to throw money (=upgraded laptops) at us, so I need to show some sort of benchmark. It has been many years since I did any system benchmarking, and I don't know the current benchmark software, so my question is which benchmark will be most relevant for Visual Studio performance? Not just for compiling fast, but also to reflect the "responsiveness" of the system. Cheers, user30715

  • IBM laptop remove access-connections

    I installed IBM Access Connections on my IBM t61 laptop to manage my wireless connections but it simply will not connect to my network. I want to uninstall it and try the Intel software which is capable to performing the same task. However, when I go into "Control Panel" - "Add/Remove Programs" and try to "Remove" this package, it simply opens up a screen and closes it immediately. This happens too fast for me to see whether its an error. Has anyone encountered this issue ? The event logs do not show any error.

  • Perform action based on load avg

    - by sfx
    I'm running some web applications on an debian server and have to struggle with ddos attacks sometimes. It's eating up all my resources and I can't ssh anymore into the server. An idea was to drop all connections if the load avg is too high, so there are still resources for me and accept new connections if the load avg is low enough. Since this has to work under heavy load I'm afraid a cronjob wouldn't be fast enough or take too much resources. tl;dr: Is there a way to configure the behavior if the load avg is above a specific threshold?

  • Limit disk I/O one program creates?

    - by Posipiet
    Hardware: one virtualization server. Dual Nehalem, 24GB RAM, 2 TB mirrored HD. Software: Debian, KVM, virt-manager on the server with several virtual machines that use Linux too. 2 TB Disk is a big LVM, each VM gets a logical volume and makes its own partitions in that. Problem: One of the programs that runs on one of the VMs creates huge disk load. This never was an issue, because the program never ran on such a powerful hardware. Now the CPUs are fast, and lots of I/O is the result. We cant do much against that at the moment, because the tool is a black box. On the other hand, the speedy computation is welcome. The program creates about 5 GB of temp files which get overwritten during the next iteration. Question: How can we limit the disk I/O for the process?

  • CAsyncSocket and ThreadPool problem

    - by zabulus
    I have a server application with such structure: There is one object, call him Server, that in endless cycle listens and accepts connections. I have descendant class from CAsyncSocket, that has overriden event OnReceive, call him ProxySocket. Also I have a thread pool with early created threads. When connection is received by server object he accepts the new connection on the new object ProxySocket. When data arrives to the ProxySocket, he creates a command object and gives it to thread pool. In this command object I giving the socket handle of a ProxySocket. When new object of command is creating - I creating a new Socket in working thread and attach handle to it. My issue is next: When command ends, socket doesn't close, I just detach handle it and set CSocket handle to INVALID_SOCKET value, as planned. But my first ProxySocket object doesn't receives messages of new data receiving after that. How can I solve this?

  • distributed, fault-tolerant network block device

    - by gucki
    I'm looking for a distributed, fault-tolerant network storage system which exposes block devices (not filesystems) on the clients. A client's block device should write simultaneously to several storage nodes A client's block device should not fail as long as not all storage nodes backing it went down The master should automatically redistribute storages' data when a storage node fails or gets added/ removed A single master (which is for metadata only) is fine So ideally the architecture would be very similar to moosefs (http://www.moosefs.org/) but instead of exposing a real filesystem mounted using a fuse client it'd expose block devices on the clients. I know of iscsi and drbd but both don't seem to offer what I'm looking for. Or am I missing something?

  • IIS's SMTP Pickup timing

    - by fatcat1111
    I have IIS's SMTP server set up as a closed relay, and it's working nicely. I also have an application that writes EML files. If the EML files are written to a temporary directory, then moved to the server's Pickup directory, email is sent as expected. However, if I have the application write the EML files directly to the Pickup directory, the email will often fail to send. This seems to be a race condition: the server starts processing the EML file as soon as it detects it in Pickup, even though the application hasn't completed writing it. The result is the server considers the EML to be malformed, and it punts it to Badmail. While I very much appreciate the server's earnestness, it seems that I need to dial it back a bit for this scenario. Does anybody know if IIS's SMTP server's polling frequency can be configured? I am using IIS7, Windows Server 2008 R2. The application that writes the EML cannot be modified.
