  • Using delayed_job to process file uploads across multiple servers

    - by Steve Klabnik
    Does anyone have any good resources on how to do this? Basically, I'm working on a project (in Rails) where people can upload files. They might be big. I'd like to process them using delayed_job before sending them to S3. I'd also like to do this processing on a separate job queue server, rather than on the webserver itself. I'd rather not have to upload the files to the webserver, then transfer them to the job queue server, and then upload them to S3 if I don't have to. Thanks.

  • File Hierarchy system with a web application logic question: List searching

    - by molleman
    I need to search through a list of folders that could have more folders inside it, and add a new folder depending what folder is its parent.(the path is stored as a String for eg = "root/MyCom/home/") Then i fill in a field with a new folder name and add it to the final folder(eg "home/"). Below as you can see , I can navigate to the right location and add the new folder to a current folder, My trouble is that i cannot ensure that currentFolder element is placed back in the list it came from how could i add a folder to a list of folders, that could be within a list of folders,that could be within a list of folders and endless more? YFUser user = (YFUser)getSession().getAttribute(SESSION_USER); Folder newFolder = new Folder(); newFolder.setFolderName(foldername); // this is the path string (root/MyCom/home/) split in the different folder names String folderNames[] = folderLocationString.split("/"); int folderNamesLength = folderNames.length; Folder root = user.getRoot(); Folder currentFolder = root; for(int i=0;i<=folderNamesLength; i++){ // because root is folderNames[i] String folderName = folderNames[i++]; int currentFolderSize = currentFolder.getChildren.getSize(); for(int o=1; o<= currentFolderSize ; o++){ if(currentFolder.getChildren().get(o) instanceof Folder){ if(folderName.equals(currentFolder.getChildren().get(o).getFolderName())){ currentFolder = currentFolder.getChildren().get(o); if (i == counter){ //now i am inside the correct folder and i add it to the list of folders within it //the trouble is knowing how to re add this changed folder back to the list before it currentFolder.getChildren.add(newFolder); } } } } }

  • gvim "open in new window" should change directory to the one of the current file

    - by Flavius
    Hi I'm working in gvim with sessions and tabs, and everything works great. However there is something that is bothering me. Say I have two files open: /A/B/foo.ext and /C/D/E/bar.ext, the latter being opened last. Now say I want to open /A/B/foobar.ext. I have to go through the hassle of navigating upwards to / and from there to /A/B. I would like to simply change my active tab to /A/B/foo.ext and have gvim automatically change its active directory to /A/B/, so that when I want to open /A/B/foobar.ext with /A/B/foo.ext being active, I'm already in the right CWD. This would be very time-saving if you work with two different projects at a time and need to switch back and forth between the two. Is there any such script that does just that? Thanks.

  • Eclipse: view a document using custom spacing, save using the file's spacing

    - by Steven Sproat
    I have a silly use case for eclipse: At work, they use 2 spaces for a tab character. Indentation looks really squashed and I'm finding it obstructs readability. Now, I can't set Eclipse to use 4 spaces for a tab as it'll edit any files I change, and obviously don't want to violate the coding standards. So, can I have a custom view onto my document, with saving maintaining the original spacing? Cheers

  • Showing errors in updatepanel after processing a CSV file

    - by Younes
    I have a csv importroutine which imports my CSV values into Sitecore. After this proces is done i want to show the errors in an asp:literal. This is not working, and I think this is because i need an updatepanel for this in order to be able to update text after the first postback (the csv upload / import). I made this: <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder> <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" /> </ContentTemplate> </asp:UpdatePanel> and coded this: string melding = string.Format("Er zijn {0} objecten geïmporteerd.{1}", nrOfItemsImported, errors); ViewState["Melding"] = melding; And i have a button. On the onclick of this button I have: Literal literal = new Literal(); literal.Text = (string)ViewState["Melding"]; literal.ID = DateTime.Now.Ticks.ToString(); UpdatePanel1.ContentTemplateContainer.Controls.Add(literal); PlaceHolder1.Controls.Add(literal); When i now press the button i want to update the panel so that it will show my Literal with the errormsg on it. This however isn't happening. How can this be? I'm guessing it has something to do with my viewstate, i don't see keys on the viewstate after I press the button...

(expect: "File1-1" display only in "Folder2") What happen? How can i solve this problem?

  • Creating managed file transfer software in java

    - by Shekhar
    Hello, I have been asked to do some POC on how we can provide a software solution which will be able to manage files. Manage files means it will be able to move files from source to destination servers. The client gave us 4 page document detailing what sort of software they are looking for. They dont want to use existing commercial softwares. They want to build their own customizable software. Has anybody worked on this type of project? Please provide your inputs on how should i approach this project. The software should be platform independent and should be built in java.

  • How do I run a batch file async using PSExec?

    - by Paul Mrozowski
    I have a batch file I run that, among other things, reset's the NICs in the machine. I have some watchdog software running on another machine that monitors the first one. I'd like to run this batch file using PSExec when it detects certain types of failures. The problem I'm having is that since the batch file reset's the NIC's it kills the connection PSExec has (I'm OK with that). The real issue is that when PSExec dies the batch file stops running (leaving the NIC's disabled). I've tried using the -i option with PSExec with no luck. Any ideas about basically just fire off the batch file and NOT have it stop when PSExec is disconnected?

  • Add webservice reference, the classes in different file

    - by ArunDhaJ
    Hi, When I add webservice as service reference in my .Net project, it creates a service folder within "Service References". All the interfaces and classes are contained within that service folder. I wanted to know how to split the interface's method and classes. Actually I wanted the web service reference to import classes defined in different dll. I wanted to define this way because of my design constraints. I've 3 layered application. Of which third layer is communication layer which holds all web service references. second is business layer and first is presentation layer. If the class declarations are in layer-3 and I'm accessing those classes from presentation layer, it is logically a cross-layer-access-violation. Instead, I wanted a separate project which holds only the class declarations and this would be used in all 3 layers. I didn't faced any problems to achieve this with layer-1 and layer-2. But, I'm not sure how to make communication layer to use this common declaration dll. Your suggestion would help me to design my application better. Thanks in advance Regards ArunDhaJ

  • Shrinking a Linux OEL 6 virtual Box image (vdi) hosted on Windows 7

    - by AndyBaker
    v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Recently for a customer demonstration there was a requirement to build a virtual box image with Oracle Enterprise Manager Cloud Control 12c. This meant installing OEL Linux 6 as well as creating an 11gr2 database and Oracle Enterprise Manager Cloud Control 12c on a single virtual box. Storage was sized at 300Gb using dynamically allocated storage for the virtual box and about 10Gb was used for Linux and the initial build. After copying over all the binaries and performing all the installations the virtual box became in the region of 80Gb used size on the host operating system, however internally it only really needed around 20Gb. This meant 60Gb had been used when copying over all the binaries and although now free was not returned to the host operating system due to the growth of the virtual box storage '.vdi' file.  Once the ‘vdi’ storage had grown it is not shrunk automatically afterwards. Space is always tight on the laptop so it was desirable to shrink the virtual box back to a minimal size and here is the process that was followed. Install 'zerofree' Linux package into the OEL6 virtual box The RPM was downloaded and installed from a site similar to below; http://rpm.pbone.net/index.php3/stat/4/idpl/12548724/com/zerofree-1.0.1-5.el5.i386.rpm.html A simple internet search for ’zerofree Linux rpm’ was easy to perform and find the required rpm. Execute 'zerofree' package on the desired Linux file system To execute this package the desired file system needs to be mounted read only. The following steps outline this process. As root: # umount /u01 As root:# mount –o ro –t ext4 /u01 NOTE: The –o is options and the –t is the file system type found in the /etc/fstab. Next run zerofree against the required storage, this is located by a simple ‘df –h’ command to see the device associated with the mount. As root:# zerofree –v /dev/sda11   NOTE: This takes a while to run but the ‘-v’ option gives feedback on the process. What does Zerofree do? Zerofree’s purpose is to go through the file system and zero out any unused sectors on the volume so that the later stages can shrink the virtual box storage obtaining the free space back. When zerofree has completed the virtual box can be shutdown as the last stage is performed on the physical host where the virtual box vdi files are located. Compact the virtual box ‘.vdi’ files The final stage is to get virtual box to shrink back the storage that has been correctly flagged as free space after executing zerofree. On the physical host in this case a windows 7 laptop a DOS window was opened. At the prompt the first step is to put the virtual box binaries onto the PATH. C:\ >echo %PATH%   The above shows the current value of the PATH environment variable. C:\ >set PATH=%PATH%;c:\program files\Oracle\Virtual Box;   The above adds onto the existing path the virtual box binary location. C:\>cd c:\Users\xxxx\OEL6.1   The above changes directory to where the VDI files are located for the required virtual box machine. C:\Users\xxxxx\OEL6.1>VBoxManage.exe modifyhd zzzzzz.vdi compact  NOTE: The zzzzzz.vdi is the name of the required vdi file to shrink. Finally the above command is executed to perform the compact operation on the ‘.vdi’ file(s). This also takes a long time to complete but shrinks the VDI file back to a minimum size. In the case of the demonstration virtual box OEM12c this reduced the virtual box to 20Gb from 80Gb which was a great outcome to achieve.

  • Makefile and rm -f file.{ext1,ext2,ext3} issue

    - by ak91
    Hello, Could you explain me, why Makefile rule: clean: rm -f foo.{bar1,bar2,bar3} does not result in removing files: foo.bar1 foo.bar2 and foo.bar3? I believe I saw pattern like that many times in various Makefiles, but I'm currently writing my own Makefile and can't make that rule work correctly (no files are removed). I'm using: gnu make 3.81 gnu bash 4.1.5 Bash evals that pattern as I suspect: $ echo test.{a,b,c} test.a test.b test.c Thanks!

  • How to diff two regions of the same file in Eclipse

    - by Thomas Nilsson
    I'm a TDDer and often have a need to refactor out common or similar code. If it is exactly the same there is no big problem, Eclipse can almost always do that by itself. But to get there I'm finding myself often looking at similar, but not identical, code fragments in the same, or even different, files. It would be very handy if there was a possibility to mark two regions and get Eclipse (or some other tool) to mark the differences. With this information it would be much simpler to iteratively move the regions closer until they are the same and then activate the Extract Method refactoring. It can be done in Emacs of course, but I'd like to have this readily available from Eclipse. Any pointers?

  • using string to read file - XCode

    - by Fernando
    The following does not work and gives me a SIGABRT when I run in the debugger: std::ifstream inFile; inFile.open("/Users/fernandonewyork/inputText.txt"); cout << inFile << endl; vector<string> inText; if (inFile) { string s4; while (inFile>>s4) { inText.push_back(s4); } } inFile.close(); The following does: std::ifstream inFile; inFile.open("/Users/fernandonewyork/inputText.txt"); cout << inFile << endl; vector<string> inText; if (inFile) { string s4("This is no lnger an empty string"); while (inFile>>s4) { inText.push_back(s4); } } inFile.close(); I was under the impression I was able to simply use s4 without having to worry about any space considerations, or is something else happening here? This is the full error I get from the top code: malloc: * error for object 0x100010a20: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug Program received signal: “SIGABRT”.
