  • Redirecting multiple stdouts to single file

    - by obvio171
    I have a program running on multiple machines with NFS and I'd like to log all their outputs into a single file. Can I just run ./my_program >> filename on every machine or is there an issue with concurrency I should be aware of? Since I'm only appending, I don't think there would be a problem, but I'm just trying to make sure.

  • How does a historical debugger work?

    - by mafutrct
    A historical debugger is able to revert program state (including current instruction) to a former state. How is this possible in managed or unmanaged environments? I can't imagine that the debugger takes a state shot of the whole system on every instruction.

  • Getting a screenshot of a page using .NET - Need help with code

    - by Ender
    I'm writing a specialized crawler and parser for internal use and I require the ability to take a screenshot of a web page in order to check what colours are being used throughout. The program will take in around ten web addresses and will save them as a bitmap image, from there I plan to use LockBits in order to create a list of the five most used colours within the image. To my knowledge it's the easiest way to get the colours used within a web page but if there is an easier way to do it please chime in with your suggestions. Anyway, I was going to use this program until I saw the price tag. I'm also fairly new to C#, having only used it for a few months. Can anyone provide me with a solution to my problem of taking a screenshot of a web page in order to extract the colour scheme? EDIT: Sorry for not getting back to this sooner, but I've been busy with some other things. Anyway, the code seems to work well, but the problem I am having right now is that I am running it within a form, and naturally with Application.Run() being called I cannot run two instances of the same form at once. It recommended Form.showDialog() but that broke everything. Can anyone give me a hand with this code? public static void buildScreenshotFromURL(string url) { int width = 800; int height = 600; using (WebBrowser browser = new WebBrowser()) { browser.Width = width; browser.Height = height; browser.ScrollBarsEnabled = true; // This will be called when the page finishes loading browser.DocumentCompleted += new System.Windows.Forms.WebBrowserDocumentCompletedEventHandler(OnDocumentCompleted); //browser.DocumentCompleted += OnDocumentCompleted; browser.Navigate(url); // This prevents the application from exiting until // Application.Exit is called // Application.Run() does not work as it cannot be called twice, recommended form.showDialog() // but still issues Application.Run(); } } public static void OnDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { // Define size of thumbnail neded int thumbSize = 50; // Now that the page is loaded, save it to a bitmap WebBrowser browser = (WebBrowser)sender; // Code edited from example below to make smaller bitmap and save as PNG using (Graphics graphics = browser.CreateGraphics()) { using (Bitmap bitmap = new Bitmap(browser.Width, browser.Height, graphics)) { Rectangle bounds = new Rectangle(0, 0, bitmap.Width, bitmap.Height); browser.DrawToBitmap(bitmap, bounds); Bitmap thumbBitmap = new Bitmap(bitmap.GetThumbnailImage(thumbSize, thumbSize, thumbCall, IntPtr.Zero)); thumbBitmap.Save("screenshot.png", ImageFormat.Png); handleImage(thumbBitmap); } }

  • Reliable and fast way to convert a zillion ODT files in PDF?

    - by Marco Mariani
    I need to pre-produce a million or two PDF files from a simple template (a few pages and tables) with embedded fonts. Usually, I would stay low level in a case like this, and compose everything with a library like ReportLab, but I joined late in the project. Currently, I have a template.odt and use markers in the content.xml files to fill with data from a DB. I can smoothly create the ODT files, they always look rigth. For the ODT to PDF conversion, I'm using openoffice in server mode (and PyODConverter w/ named pipe), but it's not very reliable: in a batch of documents, there is eventually a point after which all the processed files are converted into garbage (wrong fonts and letters sprawled all over the page). Problem is not predictably reproducible (does not depend on the data), happens in OOo 2.3 and 3.2, in Ubuntu, XP, Server 2003 and Windows 7. My Heisenbug detector is ticking. I tried to reduce the size of batches and restarting OOo after each one; still, a small percentage of the documents are messed up. Of course I'll write about this on the Ooo mailing lists, but in the meanwhile, I have a delivery and lost too much time already. Where do I go? Completely avoid the ODT format and go for another template system. Suggestions? Anything that takes a few seconds to run is way too slow. OOo takes around a second and it sums to 15 days of processing time. I had to write a program for clustering the jobs over several clients. Keep the format but go for another tool/program for the conversion. Which one? There are many apps in the shareware or commercial repositories for windows, but trying each one is a daunting task. Some are too slow, some cannot be run in batch without buying it first, some cannot work from command line, etc. Open source tools tend not to reinvent the wheel and often depend on openoffice. Converting to an intermediate .DOC format could help to avoid the OOo bug, but it would double the processing time and complicate a task that is already too hairy. Try to produce the PDFs twice and compare them, discarding the whole batch if there's something wrong. Although the documents look equal, I know of no way to compare the binary content. Restart OOo after processing each document. it would take a lot more time to produce them it would lower the percentage of the wrong files, and make it very hard to identify them. Go for ReportLab and recreate the pages programmatically. This is the approach I'm going to try in a few minutes. Learn to properly format bulleted lists Thanks a lot.

  • Reading HTTP server push streams with Python

    - by Sam
    I'm playing around trying to write a client for a site which provides data as an HTTP stream (aka HTTP server push). However, urllib2.urlopen() grabs the stream in its current state and then closes the connection. I tried skipping urllib2 and using httplib directly, but this seems to have the same behaviour. Is there a way to get the stream to stay open, so it can be checked each program loop for new contents, rather than waiting for the whole thing to be redownloaded every few seconds, introducing lag?

  • Set compression level when generating a ZIP file using RubyZip

    - by Vincent Robert
    Hi, I have a Ruby program that zips a directory tree of XML files using the rubyzip gem. My problem is that the file is starting to be heavy and I would like to increase the compression level, since compression time is not an issue. I could not find in the rubyzip documentation a way to specify the compression level for the created ZIP file. Anyone know how to change this setting?
