  • How to encourage Windows administrators to pick up scripting

    - by icelava
    When i worked as an administrator in my first job, I was frustrated our administration processes with Windows servers were a series of point-and-clicks; we could never match the level of efficiency with the Unix servers which had a group of shell scripts to automate a lot of the work. I soon read about WSH and ADSI and wasted no time learning just how much automation I was able to achieve with scripting. There was a huge problem though - almost none of my Windows colleagues were really interested in learning scripting. They seemed happy with the manually mouse-clicking chores and were never excited at the prospect of using scripts to do the work on their behalf. I struggled to convince them to pick up scripting skills despite the evident increases in efficiency. I left that job in pursuit of a full-time software development career thereafter. Almost a decade on working in various environments and different customers, I still encounter Windows administrators mainly possessing this general "mood" where they would avoid scripting as much as possible. Despite the increasing level of accessibility Windows server technologies are opening up for scripting and automation. I am almost certain the majority of administrators are administrators precisely because they absolutely hate performing any kind of programming duties. What are some means to encourage and motivate administrators that scripting can really help them in the long run?

  • ffmpeg hangs when creating a video

    - by FearUs
    I am trying to insert an audio channel with a video: first of all I extract the audio from the original video for processing: ffmpeg -i lotr.mp4 lotr.wav I then extract all frames for later processing too: ffmpeg -i lotr.mp4 -f image2 %d.jpg When done processing audio and video streams, I try to create the video ffmpeg -f image2 -r 15 -i %d.jpg new.mp4 then merge with the audio: ffmpeg -i new.mp4 -i lotr.wav -map 0:0 -map 1:0 new_w_audio.mp4 Result: CPU activity = 100%, the process hangs and never returns.

  • SmartSVN - Unable to create new repository profile

    - by Sandeepan Nath
    I have just installed SmartSVN on this fedora system. The application starts (on running ./smartsvn.sh) with its usual UI but many things are not working. Creating New repository profile Trying to create a new repository profile (Repositories- Repository Profiles- Add) An Error occurred while processing an SVN command - Cannot connect to 'svn+ssh://192.168.0.103': There was a problem while connecting to 192.168.0.103:22 Quick Checkout Trying to do Quick Checkout (less configuration) An Error occurred while processing an SVN command - Malformed XML. Some Observations When I run the smartsvn.sh file like this:- ./smartsvn.sh It shows this in the console - Warning: /bin/java does not exist Could not lock /root/.smartsvn/_lock_ Switched to running instance I was using SmartSVN in another system before this where it was working. There too, it was showing the warning like Warning: /bin/java does not exist but this part was not showing:- Could not lock /root/.smartsvn/_lock_ Switched to running instance I have only JRE installed in both the systems and not JDK. So, what could be the reason? Any pointers? Thanks, Sandeepan

  • forward mails from sendmail + mimedefang on two unix boxes

    - by SWKK
    I am not a unix expert, more like a novice. I have one user account replicated on two unix boxes receiving same mails on both boxes for fail over. Sendmail has mimedefang utility running to process these mails. After all the processing is complete, more like weeding the spam, viruses etc. I need to forward these mails coming to the same account on both boxes to goto a central mailbox on MS Exchange for this account. Problem is I am using .forward file hence both unix boxes forward the mail after processing. I just want to be able to ignore one of the two mails. Has anyone tried something similar? any directions? Please?

  • Choosing between a dedicated and virtual dedicated server for my startup

    - by MarathonStudios
    I'm about to launch a startup site I've been working on for some time, and I'm just now looking over hosting plans. The site's main feature is fairly processor-heavy (a lot of text processing), so I probably need something other then shared hosting to ensure I don't get shut down for overusing resources. I would like to spend as little as possible on hosting until the site starts generating income, so under-$60/mo is my goal. One caveat is that I need a Windows box for this particular site, so it's harder to get a good deal. For that price, I can either get a bottom-tier dedicated (2gigs ram, pentium 4) or a middle-tier VPS (3gb RAM, a bit more traffic and HD) for a few bucks more per month. I had a bad experience with a low-end VPS a few months ago, so making sure that whatever I get can handle the basic traffic of a website as well as giving me what I need (extra processing power) is essential. Do you have any suggestions as to which way to go, or a certain hosting company you've worked with that you can recommend?

  • How to directly rotate CVImageBuffer image in IOS 4 without converting to UIImage?

    - by Ian Charnas
    I am using OpenCV 2.2 on the iPhone to detect faces. I'm using the IOS 4's AVCaptureSession to get access to the camera stream, as seen in the code that follows. My challenge is that the video frames come in as CVBufferRef (pointers to CVImageBuffer) objects, and they come in oriented as a landscape, 480px wide by 300px high. This is fine if you are holding the phone sideways, but when the phone is held in the upright position I want to rotate these frames 90 degrees clockwise so that OpenCV can find the faces correctly. I could convert the CVBufferRef to a CGImage, then to a UIImage, and then rotate, as this person is doing: Rotate CGImage taken from video frame However that wastes a lot of CPU. I'm looking for a faster way to rotate the images coming in, ideally using the GPU to do this processing if possible. Any ideas? Ian Code Sample: -(void) startCameraCapture { // Start up the face detector faceDetector = [[FaceDetector alloc] initWithCascade:@"haarcascade_frontalface_alt2" withFileExtension:@"xml"]; // Create the AVCapture Session session = [[AVCaptureSession alloc] init]; // create a preview layer to show the output from the camera AVCaptureVideoPreviewLayer *previewLayer = [AVCaptureVideoPreviewLayer layerWithSession:session]; previewLayer.frame = previewView.frame; previewLayer.videoGravity = AVLayerVideoGravityResizeAspectFill; [previewView.layer addSublayer:previewLayer]; // Get the default camera device AVCaptureDevice* camera = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo]; // Create a AVCaptureInput with the camera device NSError *error=nil; AVCaptureInput* cameraInput = [[AVCaptureDeviceInput alloc] initWithDevice:camera error:&error]; if (cameraInput == nil) { NSLog(@"Error to create camera capture:%@",error); } // Set the output AVCaptureVideoDataOutput* videoOutput = [[AVCaptureVideoDataOutput alloc] init]; videoOutput.alwaysDiscardsLateVideoFrames = YES; // create a queue besides the main thread queue to run the capture on dispatch_queue_t captureQueue = dispatch_queue_create("catpureQueue", NULL); // setup our delegate [videoOutput setSampleBufferDelegate:self queue:captureQueue]; // release the queue. I still don't entirely understand why we're releasing it here, // but the code examples I've found indicate this is the right thing. Hmm... dispatch_release(captureQueue); // configure the pixel format videoOutput.videoSettings = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithUnsignedInt:kCVPixelFormatType_32BGRA], (id)kCVPixelBufferPixelFormatTypeKey, nil]; // and the size of the frames we want // try AVCaptureSessionPresetLow if this is too slow... [session setSessionPreset:AVCaptureSessionPresetMedium]; // If you wish to cap the frame rate to a known value, such as 10 fps, set // minFrameDuration. videoOutput.minFrameDuration = CMTimeMake(1, 10); // Add the input and output [session addInput:cameraInput]; [session addOutput:videoOutput]; // Start the session [session startRunning]; } - (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection { // only run if we're not already processing an image if (!faceDetector.imageNeedsProcessing) { // Get CVImage from sample buffer CVImageBufferRef cvImage = CMSampleBufferGetImageBuffer(sampleBuffer); // Send the CVImage to the FaceDetector for later processing [faceDetector setImageFromCVPixelBufferRef:cvImage]; // Trigger the image processing on the main thread [self performSelectorOnMainThread:@selector(processImage) withObject:nil waitUntilDone:NO]; } }

  • Problem upgrading kernel on debian 3.1

    - by exhuma
    Hi, I have a quite old box in a remote server farm. So I have no direct access. Only remote SSH (and via SSH to a serial console). I haven't updated this box in ages. Now, whenever I want to install a new package, a dependency to glibc appears. Unfortunately, the install of glibc depends on a 2.6 kernel and I am running a venerable 2.4 kernel (one more reason to upgrade). The problem is, that the install of a new kernel has an indirect (over locales) dependency to glibc. So, to install glibc, I need a new kernel. For a new kernel, I need to upgrade glibc. Essentially I am blocked. What's the best way to proceed considering I have no "hardware" access?

  • 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!

  • Do I need to retain Sharepoint usage analysis log files

    - by dunxd
    Our Sharepoint installation currently has 30Gb of Usage Analysis Log file - these date back about six months. I have configured Sharepoint to do Usage Analysis Processing every night, so I am wondering whether I need to keep these files for so long. Sharepoint doesn't seem to clean up these files automatically - I think six months ago I had to clear out logs due to disk space issues. So my question is, do I need to retain these files in order to get decent usage analysis reports, or can I delete them as soon as the usage analysis processing has completed?

  • Multiple Graphics cards - Non Multi-Display Setup

    - by Alan Thomas
    Is it possible for me to utilize the processing capabilities of multiple graphics cards, even if I'm only using one monitor? I recently bought a new AMD graphics card, fairly top of the line. I also have a two year old, decent nVidia card. They're obviously very different cards. I don't really mind for gaming because my current card can handle most games fine by itself. I'm concerned about video editing programs such as Adobe Premiere and After Effects. Would the system be able to utilize the power of both cards to, say, render a video? I have both drivers still installed on my machine. And because there is only one monitor connected to my current graphics card (AMD) the nVidia would be connected to no display. So I am wondering whether it would or could be utilized in some way to help in processing video. Thanks!

  • Ubuntu can't install an older version of a package

    - by Trevor Newhook
    When I try to do an apt-get install, I keep getting an error: Depends: libgtk-3-common (= 3.4.1-0ubuntu1) but 3.4.2-0ubuntu0.4 is to be installed when I run sudo apt-get -f install, I get several dpkg: warning: files list file for package 'XXX' missing, assuming package has no files currently installed. then Preparing to replace libgtk-3-bin 3.4.1-0ubuntu1 (using .../libgtk-3-bin_3.4.2-0ubuntu0.4_i386.deb) ...

  • How to make a quiet laptop?

    - by psihodelia
    Most modern laptops have very noisy fans. I am looking for a quiet laptop or a small stationary computer which has all its hardware built in a display. Most tasks will be PDF/docs processing, real-time audio processing, web-surfing and Skype video chats. Certainly, there is no any fan-less model today; but maybe some of the existed laptops do not switch on their fans so often or implement different solutions? For example, an iPad has no fan at all and it is fast enough for my needs, but it has no normal operating system, so I can't use it for anything but audio chats and web-surfing. Or maybe I can buy a laptop and tweak it to make it absolutely noiseless? Can you recommend any solution please?

  • Display CPU usage separately (without root privileges)

    - by synaptik
    I need to display the CPU usage for each processing core on a single shared-memory 12-core (SMP) machine. I don't have access to install htop, else I would simply use that. I don't need fancy graphs or meters, though they would be nice. For example, simply displaying: X X X X X X X X X X X X where each X is the percentage utilization of 1 of the 12 processing cores on my machine. FYI: I know I can simply look at the utilization in "top" and divide that number by the number of cores on my machine, but I prefer a solution that shows each core separately.

  • Hardware recommendations for building an Ubuntu encrypted file server

    - by Robert Mashlan
    I would like to build a file server for my home network using Ubuntu. It will serve files from RAID1 configured disks, either in the OS or in hardware. It will be connected to a Gigabit ethernet LAN. The disks will use an encrypted file system. It will serve samba shares. I would like a recommendation on what kind of processing power/memory I would need to build a box that would be able to sustain the full capacity of the Gigabit ethernet connection in a file transfer for a single connection with the overhead of serving from an encrypted disk. I'm not looking to build a dream server, I just want enough processing capacity for high performance (and reliable) file sharing and spend as little as possible for it. This may be tangential, but what kind of hardware would I need to have a server be able to reliably go into a low power mode when no requests are being made of it?
