  • Howto boot directly into a VirtualBox image?

    - by mawimawi
    I have a running setup as following: Native OS: Windows 7 64bit, 3 Partitions: c: (System) d: (FAT32, here is my vdi file) e: (unformatted) VirtualBox: Fedora 14 running off the vdi file on drive d. Usually this setup is great for me, but sometimes I'd like to run Linux natively, and not inside VirtualBox. Is there a way to boot directly into the vdi file without the Windows overhead? E.g. using a USB stick with some modified Linux Kernel / GRUB that can mount the vdi file directly as "/"? Or copy the contents of my vdi file to the empty partition and somehow use this from VirtualBox (when booting into Windows) AND directly booting into Linux? Hope to get some hints or even howtos.

  • Can't double click files to open them in inDesign (CS5)

    - by Matt
    I cannot open a file unless I open inDesign (the program) and then do File-Open If I double click, it starts to open, then just hangs forever. AFTER I close it, and look in the directory where they're saved, I see a (temporary?) "lock" file. Now I can double click the original file and it opens just fine. However, now when I close iD it deletes the file and the whole process starts again... I have tried updating the software, uninstalled COMPLETELY and reinstalled, tried a brand new Win7 install. These files are all saved on a network drive, the computer is a new quad-core Dell with 12GB of RAM and a fresh x64 Win7 install on the SSD. Does not happen with other programs.

  • Complete RESTful API debugging/testing tool

    - by vartec
    I'm looking for the most complete tool, preferably portable GUI or browser plugin to test RESTful API. What I need is: GET/POST/DELETE/PUT support multiple file uploads as fields (multipart/form-data) file uploads as body Extra points for: possibility to save multiple configurations and use them to pre-fill parameters OAuth support nice JSON response formatting Currently I'm using 3 tools: Chrome REST Console extension — My favorite, very nicely done. Has OAuth. However the functionality missing for me is sending file as a body of the request; Cannot send multiple files; Firefox Poster add-on — Quite nice, but the functionality it's missing for file as POST fields parameters; Also cannot send multiple files; cURL — can do anything, but it's quite tedious to use it from command line.

  • How to completely integrate Nemo with Ubuntu?

    - by user74660
    I have installed Nemo (a fork of Nautilus created by the Linux Mint Team) in my Ubuntu 12.04.1 LTS with Gnome Shell 3.4.2. I followed the instructions here (https://help.ubuntu.com/community/DefaultFileManager), changing the "inode" and "x-directory" in the file "defaults.list", to make Nemo my default file manager. Now everything works perfectly, except for one thing: opening folders from desktop. I have set the option "Have file manager handle the desktop" on. Cool. The problem is that the desktop seems to be handled by Nautilus only, even if I have set another file manager as default. Every time I double click a folder on the desktop, it is opened by Nautilus, not Nemo. Please, does anybody know how to fix this? Thanks for your time. :)

  • double-click does not open the default program

    - by Chang
    I installed Ubuntu 12.04, with texlive-full and texworks. When I double-click a .tex file in Nautilus, it pops up a Do you want to run "xxxxxxxx.tex", or display it contents? "xxxxxxxx.tex" is an executable text file. Run in Terminal Display Cancel Run If I choose Display, it opens texworks. How can I make it open without seeing the above conversation window? By the way, is .tex file indeed an executable file? ADDED Just for the case, my ~/.local/share/applications/mimeapps.list file looks like the following: [Default Applications] text/html=google-chrome.desktop x-scheme-handler/http=google-chrome.desktop x-scheme-handler/https=google-chrome.desktop x-scheme-handler/about=google-chrome.desktop x-scheme-handler/unknown=google-chrome.desktop text/x-tex=texworks.desktop x-scheme-handler/mailto=google-chrome.desktop [Added Associations] text/x-tex=texworks.desktop; text/x-bibtex=jabref.desktop;gedit.desktop; I observe texworks are both up and down. Should I remove one? ADDED This does not happen with all .tex files. In fact, I am currently using Ubuntu 12.04 under Virtual Box with Windows 7 host. I have my Dropbox account synced with the Windows 7 host, and I access files in Dropbox in Ubuntu through Virtual Box's shared folder functionality. (I didn't install Dropbox client in Ubuntu.) Files in Dropbox are owned by root with group vboxsf. My personal account is in the group vboxsf. It seems that I have to uncheck the option for "executable", but I have all my .tex files in the Dropbox shared folder. Would there be any workaround?

  • MIT and copyright

  • Need instructions how to create wpa_supplicant.conf and add fast_reauth=0 to it // WPA 2 Enterprise & frequent wlan disconnects

    - by nutty about natty
    Like many other natty users on a university / academic network, I'm experiencing annoying frequent disconnects / hangs / delays. See, for instance: https://bugs.launchpad.net/ubuntu/+source/wpasupplicant/+bug/429370 I would like to learn how to add fast_reauth=0 to the wpa_supplicant.conf file. This file, it seems, does not exit by default, and needs to be manually created first: http://w1.fi/gitweb/gitweb.cgi?p=hostap.git;a=blob_plain;f=wpa_supplicant/README [quote] You will need to make a configuration file, e.g., /etc/wpa_supplicant.conf, with network configuration for the networks you are going to use. [unquote] Further, I installed wpa_gui which probably needs to be launched with parameters, else it's pretty blank... What I'm hoping for is this: That creating a wpa_supplicant.conf file with fast_reauth=0 in it, saving it to the relevant path, will work and make my uni wireless (more or even completely) stable. I read mixed reviews about wicd (as an alternative to the network manager). Also note that on my basic wlan at home (with bog-standard wpa encryption) the connection is stable. Thanks!

  • Setting up dual monitors, Xorg.conf issues

    - by JTS
    I just got a new computer (W520, Graphics card nVidia GF106 [Quadro 2000]) and installed ubuntu on it using wubi. I have everything working, so I wanted to set it up to be able to use two monitors with an extended screen. I figured I had to edit Xorg.conf, but the file didnt exist. So I tried to create it by booting in recovery mode, and executing Xorg -configure but I am getting these errors: (EE) Failed to load module "vmwgfx" (module does not exist, 0) (EE) vmware: Please ignore the above warnings about not being able to load module/driver vmwgfx (++) Using config file: "/root/xorg.conf.new" (==) Using system config directory "/usr/share/X11/xorg.conf.d" (EE) [drm] No DRICreatedPCIBusID symbol Number of created screens does not match number of detected devices. Configuration failed. ddxSigGiveUp: Closing log Any idea how I can get Xorg -configure to work, so that I can have an xorg.conf file that I can edit to enable twinview? EDIT: Another way I could ask the same question to solve this problem is, why can't I boot with an xorg.conf file generated by nvidia-xconfig? Is there something in the generated xorg.conf file that might need editing?

  • How to Banish Duplicate Photos with VisiPic

    - by Jason Fitzpatrick
    You meant well, you intended to be a good file custodian, but somewhere along the way things got out of hand and you’ve got duplicate photos galore. Don’t be afraid to delete them and lose important photos, read on as we show you how to clean safely. Deleting duplicate files, especially important ones like personal photos, makes a lot of people quite anxious (and rightfully so). Nobody wants to be the one to realize that they deleted all the photos of their child’s first birthday party during a hard drive purge gone wrong. In this tutorial we’re going to show you how to go beyond the limited reach of  tools which simply compare file names and file sizes. Instead we’ll be using a program that combines that kind of comparison with actual image analysis to help you weed out not just perfect 1:1 file duplicates but also those piles of resized for email images, cropped images, and other modified images that might be cluttering up your hard drive. How to Banish Duplicate Photos with VisiPic How to Make Your Laptop Choose a Wired Connection Instead of Wireless HTG Explains: What Is Two-Factor Authentication and Should I Be Using It?

  • How to Use KDE Dialogs in Gtk Apps

    - by MountainX
    I want to use KDE file dialogs (file open, file save) in Firefox in Kubuntu 12.04. This requires something like the ancient KGtk script, but for KDE 4.x and recent Firefox versions. Does such a thing exist? Note, I'm not asking about theming/looks. I'm asking about actually using KDE file dialogs instead of XUL or GTK dialog. And the preference ui.allow_platform_file_picker doesn't affect this. I have already tried setting it to true and false. Neither options results in using KDE dialogs. Thanks.

  • Oracle Solaris Crash Analysis Tool 5.3 now available

    - by user12609056
    Oracle Solaris Crash Analysis Tool 5.3 The Oracle Solaris Crash Analysis Tool Team is happy to announce the availability of release 5.3.  This release addresses bugs discovered since the release of 5.2 plus enhancements to support Oracle Solaris 11 and updates to Oracle Solaris versions 7 through 10. The packages are available on My Oracle Support - simply search for Patch 13365310 to find the downloadable packages. Release Notes General blast support The blast GUI has been removed and is no longer supported. Oracle Solaris 2.6 Support As of Oracle Solaris Crash Analysis Tool 5.3, support for Oracle Solaris 2.6 has been dropped. If you have systems running Solaris 2.6, you will need to use Oracle Solaris Crash Analysis Tool 5.2 or earlier to read its crash dumps. New Commands Sanity Command Though one can re-run the sanity checks that are run at tool start-up using the coreinfo command, many users were unaware that they were. Though these checks can still be run using that command, a new command, namely sanity, can now be used to re-run the checks at any time. Interface Changes scat_explore -r and -t option The -r option has ben added to scat_explore so that a base directory can be specified and the -t op[tion was added to enable color taggging of the output. The scat_explore sub-command now accepts new options. Usage is: scat --scat_explore [-atv] [-r base_dir] [-d dest] [unix.N] [vmcore.]N Where: -v Verbose Mode: The command will print messages highlighting what it's doing. -a Auto Mode: The command does not prompt for input from the user as it runs. -d dest Instructs scat_explore to save it's output in the directory dest instead of the present working directory. -r base_dir Instructs scat_explore to save it's under the directory base_dir instead of the present working directory. If it is not specified using the -d option, scat_explore names it's output file as "scat_explore_system_name_hostid_lbolt_value_corefile_name." -t Enable color tags. When enabled, scat_explore tags important text with colors that match the level of importance. These colors correspond to the color normally printed when running Oracle Solaris Crash Analysis Tool in interactive mode. Tag Name Definition FATAL An extremely important message which should be investigated. WARNING A warning that may or may not have anything to do with the crash. ERROR An error, usually printer with a suggested command ALERT Used to indicate something the tool discovered. INFO Purely informational message INFO2 A follow-up to an INFO tagged message REDZONE Usually used when prnting memory info showing something is in the kernel's REDZONE. N The number of the crash dump. Specifying unix.N vmcore.N is optional and not required. Example: $ scat --scat_explore -a -v -r /tmp vmcore.0 #Output directory: /tmp/scat_explore_oomph_833a2959_0x28800_vmcore.0 #Tar filename: scat_explore_oomph_833a2959_0x28800_vmcore.0.tar #Extracting crash data... #Gathering standard crash data collections... #Panic string indicates a possible hang... #Gathering Hang Related data... #Creating tar file... #Compressing tar file... #Successful extraction SCAT_EXPLORE_DATA_DIR=/tmp/scat_explore_oomph_833a2959_0x28800_vmcore.0 Sending scat_explore results The .tar.gz file that results from a scat_explore run may be sent using Oracle Secure File Transfer. The Oracle Secure File Transfer User Guide describes how to use it to send a file. The send_scat_explore script now has a -t option for specifying a to address for sending the results. This option is mandatory. Known Issues There are a couple known issues that we are addressing in release 5.4, which you should expect to see soon: Display of timestamps in threads and clock information is incorrect in some cases. There are alignment issues with some of the tables produced by the tool.

  • How can I keep directories in sync

    - by Guillaume Boudreau
    I have a directory, dirA, that users can work in: they can create, modify, rename and delete files & sub-directores in dirA. I want to keep another directory, dirB, in sync with dirA. What I'd like, is a discussion on finding a working algorithm that would achieve the above, with the limitations listed below. Requirements: 1. Something asynchronous - I don't want to stop file operations in dirA while I work in dirB. 2. I can't assume that I can just blindly rsync dirA to dirB on regular interval - dirA could contain millions of files & directories, and terrabytes of data. Completely walking the dirA tree could take hours. Those two requirements makes this really difficult. Having it asynchronous means that when I start working on a specific file from dirA, it might have moved a lot since it appeared. And the second limitation means that I really need to watch dirA, and work on atomic file operations that I notice. Current (broken) implementation: 1. Log all file & directory operations in dirA. 2. Using a separate process, read that log, and 'repeat' all the logged operations in dirB. Why is it broken: echo 1 > dirA/file1 # Allow the 'log reader' process to create dirB/file1: log = "write dirA/file1"; action = cp dirA/file1 dirB/file1; result = OK echo 1 > dirA/file2 mv dirA/file1 dirA/file3 mv dirA/file2 dirA/file1 rm dirA/file3 # End result: file1 contains '1' # 'log reader' process starts working on the 4 above file operations: log = "write file2"; action = cp dirA/file2 dirB/file2; result = failed: there is no dirA/file2 log = "rename file1 file3"; action = mv dirB/file1 dirB/file3; result = OK log = "rename file2 file1"; action = mv dirB/file2 dirB/file1; result = failed: there is no dirB/file2 log = "delete file3"; action = rm dirB/file3; result = OK # End result in dirB: no more files! Another broken example: echo 1 > dirA/dir1/file1 mv dirA/dir1 dirA/dir2 # 'log reader' process starts working on the 2 above file operations: log = "write file1"; action = cp dirA/dir1/file1 dirB/dir1/file1; result = failed: there is no dirA/dir1/file1 log = "rename dir1 dir2"; action = mv dirB/dir1 dirB/dir2; result = failed: there is no dirA/dir1 # End result if dirB: nothing!

  • Creating a Template Like System in cPanel

    - by clifgray
    I am creating a medium sized website using cPanel and their File Manager system and the majority of my pages are going to be the same with a different title and content section and I wanted to see if there is a system for making one general template file and then having all the other pages inherit from that file so all I have to do is have a content and title section and the rest of the links, headers, and whatnot can be changed throughout the site by just changing one file. Is there anything like this? I have used Jinaj2 in python and a few other systems for other server scripting languages but I am not sure how to implement it with cPanel.

  • Domain files download upon opening

    - by Marian
    I'm having this wierd issue with my Domain. My domain is saoo.eu hosted on HostZilla. The issue is that whenever I open an html/php file it automatically downloads it instead of opening it into the browser. Example the saoo.eu/test.html page. Same thing happens with the index.html file. What is going on? Also if I want an PHP code ran into an HTML file I have to add an .htaccess file. But it doesn't seem to work. Tested it before.

  • What do the numbers 240 and 360 mean when downloading video? How can I tell which video is more compressed?

    - by DaMing
    I have downloaded some computer science lectures from YouTube recently. There is usually more than one choice of file size and file format to download. I noticed that for the same video, the downloadable one with FLV 240 extension is larger than another one with MPEG4 360 extension. What does the number (240 and 360) mean? And which file's compression rate is bigger? That is to say, which one removed much more file elements than the other from the orignal file?

  • How do I add a shapefile in ArcGIS via python scripting?

    - by Tom W
    I am trying to automate various tasks in ArcGIS Desktop (using ArcMap generally) with Python, and I keep needing a way to add a shape file to the current map. (And then do stuff to it, but that's another story). The best I can do so far is to add a layer file to the current map, using the following ("addLayer" is a layer file object): def AddLayerFromLayerFile(addLayer): import arcpy mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] arcpy.mapping.AddLayer(df, addLayer, "AUTO_ARRANGE") arcpy.RefreshActiveView() arcpy.RefreshTOC() del mxd, df, addLayer However, my raw data is always going be shape files, so I need to be able to open them. (Equivantly: convert a shape file to a layer file wiothout opening it, but I'd prefer not to do that).

  • Using mod_rewrite to shutdown website.

    - by moolagain
    Hi, I am trying to shutdown a website to everyone except my ip address. I almost have it working. I cannot access www.mysite.com, but I can access all folders that have another .htaccess file in them. I have a .htaccess file in /www with the following code: #Use this when website is down RewriteEngine on #this allows access through my ip RewriteCond %{REMOTE_ADDR} !^(66\.777\.888\.99)$ RewriteRule !down.php$ /down.php [L] Some folders in my site have .htaccess files in them. If I have a file with the line: RewriteEngine on I can still access the folder. For example, if I have the second .htaccess file in /www/about, then I can still access mysite.com/about (but the .css file included on that page actually loads down.php). If I delete "RewriteEngine on" I get redirected to down.php. Any ideas? I think my mod_rewrite gets confused with multiple .htaccess files. Thanks!

  • What would cause different rates of packet loss between client and server in UDP?

    - by febreezey
    If I've implemented a reliable UDP file transfer protocol and I have a file that deliberately drops a percentage of packets when I transmit, why would it be more evident that transmission time increases as the packet loss percentage increases going from the client to server as opposed from the server to the client? Is this something that can be explained as a result of the protocol? Here are my numbers from two separate experiments. I kept the max packet size to 500 Bytes and the opposite direction packet loss to 5% with a 1 Megabyte file: Server to Client loss Percentage varied: 1 MB file, 500 b segments, client to server loss 5% 1% : 17253 ms 3% : 3388 ms 5% : 7252 ms 10% : 6229 ms 11% : 12346 ms 13% : 11282 ms 15% : 9252 ms 20% : 11266 ms Client to Server loss percentage varied 1 MB file, 500 b segments, server to client loss 5% 1%: 4227 ms 3%: 4334 ms 5%: 3308 ms 10%: 31350 ms 11%: 36398 ms 13%: 48436 ms 15%: 65475 ms 20%: 120515 ms You can clearly see an exponential increase in the client to server group

  • XSF-FO intellisense and national languages with Apache FOP

    - by Lukasz Kurylo
    Some time ago I showed how to get an intellisense and how to configure the FO.NET to acquire national characters inside the generated pdf files. Due to the limitations that I mensioned in my previous post, I started playing with the Apache FOP. In this post I want to show, how to acquire the same result as I showed in the two posts related to FO.NET.   Intellisense   To get the intellisense from the XSL-FO templates set the xsi:schemaLocation the same way I showed it in this post. The only diffrence to FO.NET is that, during generating the document by the code I showed last time we will get an exception:   org.apache.fop.fo.ValidationException: Invalid property encountered on "fo:root": xsi:schemaLocation (See position 6:11)   Fortunatelly there is a very easy way to resolve this without removing the entire attribute along with the intellisense. Add to the FopFactory the ignoreNamespace by:   FopFactory fopFactory = FopFactory.newInstance(); fopFactory.ignoreNamespace(http://www.w3.org/2001/XMLSchema-instance);   Notice that, the url specified in this method this is a namespace for the xmlns:xsi namespace, not xsi.schemaLocation.   Fonts / national characters   This point is a little dfferent to acquire, but not more complicated that it was with FO.NET. To set the fonts in Apache FOP 1.0, we need a configuration file. A sample one can be get from the directory where we unpacked the fop binaries, from conf subdirectory. There is a file called fop.xconf. We must copy this file to our solution. In the simplest way, in the <fonts> tag we can add  <auto-detect/>. Thanks to this, FOP will index all fonts available on the installed operating system. There probably should be no problem, if we have a http handler or a WCF Service on the server that serves the generated pdf documents. In this situation we can use all available fonts on this server.   To use this config file, we must set a path to it:   FopFactory fopFactory = FopFactory.newInstance(); fopFactory.setUserConfig(new File("fop.xconf"));

  • Where should I handle fatal exceptions

    - by Puckl
    For example, I have a controller that loads a file and hands it over to the processing. Should I handle the exception in the file loader and return Null if something is wrong, or should I throw the exception and handle it in the controller? Without the file the rest of the program can´t work. Where should I handle a exception that shuts down the program properly? I want to shut down an Android application properly.
