  • Accessibility bus warning when opening files in Eclipse from command line (Ubuntu 13.10)

    - by Reese
    Similar to closed issue Gnome Menu Broken? When opening a file from the command line for edits in Eclipse , I get this warning: ** (eclipse:nnnn): WARNING **: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. The 4-digit number at (eclipse:nnnn) changes each time I issue an 'eclipse some/file.ext' command. The file opens but the warning is an annoyance that shouldn't be happening, it may be indicative of some other problem. Updated Ubuntu 13.10 64-bit, updated Eclipse Luna.

  • A command-line clipboard copy and paste utility?

    - by Peter.O
    In Windows I used command-line clipboard copy-and-paste utilities... pclip.exe and gclip.exe These were UnixUtils ports for Windows (but they only handled plain text). There were a couple of other native Windows utils which could write/extracy any format. I've looked for something similar in Synaptic Package Manager, but I can't find anything. Is there something there, that I've missed? ... or maybe this is available in bash scripting? The type of utility I'd like will be able to read/write via std-in/std-out or file-in/file-out, and handle Unicode/Rich-text/Picture/etc clipboard formats... Late Edit: NB: I'm not after a clipboard manager.

  • Hide debug information when running apps from the command line

    - by tutuca
    Most of the time running a gtk application from the command line it starts dumping debug information to the stdio even though I put them in background. Example: ~$ gedit test.html # and ctrl+z to suspend zsh: suspended gedit .zshrc ~$ bg [1] + continued gedit .zshrc ~$ # do some editing (gedit:6208): GtkSourceView-WARNING **: Could not find word to remove in buffer (whoosh), this should not happen! (gedit:6208): GtkSourceView-WARNING **: Could not find word to remove in buffer (haystack), this should not happen! I want to note that the error, or warning, changes according to what I'm doing at the moment. The GtkSourceView-WARNING shown here is one of the cases. Anyway... Do you know if it's at all possible to avoid getting that information printed out?

  • Mount encrypted volumes from command line?

    - by cha
    If I have an encrypted external disk (or an internal disk that is not in fstab), I see an entry for it in Nautilus -- with an entry like "X GB Encrypted Volume". I can click on this volume, and am prompted for a password to decrypt and mount the device. But how do I do this from the command line? This wiki page, and other docs I can find, only refer to GUI methods of decrypting the device; but this won't do in the context of headless servers or SSH logins. Is there a simple way to get devices to mount to automatic locations in "/media" just like they would with the GUI? (I'm not asking about encrypted home directories -- I'm aware of ecryptfs-mount-private. This question is about additional encrypted volumes.)

  • Looking for an old classic book about Unix command-line tools

    - by Little Bobby Tables
    I am looking for a book about the Unix command-line toolkit (sh, grep, sed, awk, cut, etc.) that I read some time ago. It was an excellent book, but I totally forgot its name. The great thing about this specific book was the running example. It showed how to implement a university bookkeeping system using only text-processing tools. You would find a student by name with grep, update grades with sed, calculate average grades with awk, attach grades to IDs with cut, and so on. If my memory serve, this book had a black cover, and was published circa 1980. Does anyone remember this book? I would appreciate any help in finding it.

  • Editing a command-line argument to create a new variable

    - by user1883614
    I have a bash script called test.sh that uses command-line argument: lynx -dump $1 > $name".txt" But I need name to be created from the argument by specific keywords in the argument. An example is: http://www.pcmag.com/article2/0,2817,2412941,00.asp http://www.pcmag.com/article2/0,2817,2412919,00.asp Both are two separate articles but are the difference can only be seen in those 12 characters. How do I create a variable from a url for those 12 characters? So that when I run test.sh in Terminal: ./test.sh http://www.pcmag.com/article2/0,2817,2412941,00.asp there is a text file saved as 0,2817,2412941,00?

  • Imaging: Paper Paper Everywhere, but None Should be in Sight

    - by Kellsey Ruppel
    Author: Vikrant Korde, Technical Architect, Aurionpro's Oracle Implementation Services team My wedding photos are stored in several empty shoeboxes. Yes...I got married before digital photography was mainstream...which means I'm old. But my parents are really old. They have shoeboxes filled with vacation photos on slides (I doubt many of you have even seen a home slide projector...and I hope you never do!). Neither me nor my parents should have shoeboxes filled with any form of photographs whatsoever. They should obviously live in the digital world...with no physical versions in sight (other than a few framed on our walls). Businesses grapple with similar challenges. But instead of shoeboxes, they have file cabinets and warehouses jam packed with paper invoices, legal documents, human resource files, material safety data sheets, incident reports, and the list goes on and on. In fact, regulatory and compliance rules govern many industries, requiring that this paperwork is available for any number of years. It's a real challenge...especially trying to find archived documents quickly and many times with no backup. Which brings us to a set of technologies called Image Process Management (or simply Imaging or Image Processing) that are transforming these antiquated, paper-based processes. Oracle's WebCenter Content Imaging solution is a combination of their WebCenter suite, which offers a robust set of content and document management features, and their Business Process Management (BPM) suite, which helps to automate business processes through the definition of workflows and business rules. Overall, the solution provides an enterprise-class platform for end-to-end management of document images within transactional business processes. It's a solution that provides all of the capabilities needed - from document capture and recognition, to imaging and workflow - to effectively transform your ‘shoeboxes’ of files into digitally managed assets that comply with strict industry regulations. The terminology can be quite overwhelming if you're new to the space, so we've provided a summary of the primary components of the solution below, along with a short description of the two paths that can be executed to load images of scanned documents into Oracle's WebCenter suite. WebCenter Imaging (WCI): the electronic document repository that provides security, annotations, and search capabilities, and is the primary user interface for managing work items in the imaging solution SOA & BPM Suites (workflow): provide business process management capabilities, including human tasks, workflow management, service integration, and all other standard SOA features. It's interesting to note that there a number of 'jumpstart' processes available to help accelerate the integration of business applications, such as the accounts payable invoice processing solution for E-Business Suite that facilitates the processing of large volumes of invoices WebCenter Enterprise Capture (WEC): expedites the capture process of paper documents to digital images, offering high volume scanning and importing from email, and allows for flexible indexing options WebCenter Forms Recognition (WFR): automatically recognizes, categorizes, and extracts information from paper documents with greatly reduced human intervention WebCenter Content: the backend content server that provides versioning, security, and content storage There are two paths that can be executed to send data from WebCenter Capture to WebCenter Imaging, both of which are described below: 1. Direct Flow - This is the simplest and quickest way to push an image scanned from WebCenter Enterprise Capture (WEC) to WebCenter Imaging (WCI), using the bare minimum metadata. The WEC activities are defined below: The paper document is scanned (or imported from email). The scanned image is indexed using a predefined indexing profile. The image is committed directly into the process flow 2. WFR (WebCenter Forms Recognition) Flow - This is the more complex process, during which data is extracted from the image using a series of operations including Optical Character Recognition (OCR), Classification, Extraction, and Export. This process creates three files (Tiff, XML, and TXT), which are fed to the WCI Input Agent (the high speed import/filing module). The WCI Input Agent directory is a standard ingestion method for adding content to WebCenter Imaging, the process for doing so is described below: WEC commits the batch using the respective commit profile. A TIFF file is created, passing data through the file name by including values separated by "_" (underscores). WFR completes OCR, classification, extraction, export, and pulls the data from the image. In addition to the TIFF file, which contains the document image, an XML file containing the extracted data, and a TXT file containing the metadata that will be filled in WCI, are also created. All three files are exported to WCI's Input agent directory. Based on previously defined "input masks", the WCI Input Agent will pick up the seeding file (often the TXT file). Finally, the TIFF file is pushed in UCM and a unique web-viewable URL is created. Based on the mapping data read from the TXT file, a new record is created in the WCI application.  Although these processes may seem complex, each Oracle component works seamlessly together to achieve a high performing and scalable platform. The solution has been field tested at some of the largest enterprises in the world and has transformed millions and millions of paper-based documents to more easily manageable digital assets.

  • How do I get long command lines to wrap to the next line?

    - by BrianH
    Edit It was my .bashrc file. I've copied the same profile from machine to machine, and I used special characters in my $PS1 that are somehow throwing it off. I'm now sticking with the standard bash variables for my $PS1. Thanks to @ændrük for the tip on the .bashrc! ...End Edit... Something I have noticed in Ubuntu for a long time that has been frustrating to me is when I am typing a command at the command line that gets longer (wider) than the terminal width, instead of wrapping to a new line, it goes back to column 1 on the same line and starts over-writing the beginning of my command line. (It doesn't actually overwrite the actual command, but visually, it is overwriting the text that was displayed). It's hard to explain without seeing it, but let's say my terminal was 20 characters wide (Mine is more like 120 characters - but for the sake of an example), and I want to echo the English alphabet. What I type is this: echo abcdefghijklmnopqrstuvwxyz But what my terminal looks like before I hit the key is: pqrstuvwxyzghijklmno When I hit enter, it echos abcdefghijklmnopqrstuvwxyz so I know the command was received properly. It just wrapped my typing after the "o" and started over on the same line. What I would expect to happen, if I typed this command in on a terminal that was only 20 characters wide would be this: echo abcdefghijklmno pqrstuvwxyz Background: I am using bash as my shell, and I have this line in my ~/.bashrc: set -o vi to be able to navigate the command line with VI commands. I am currently using Ubuntu 10.10 server, and connecting to the server with Putty. In any other environment I have worked in, if I type a long command line, it will add a new line underneath the line I am working on when my command gets longer than the terminal width and when I keep typing I can see my command on 2 different lines. But for as long as I can remember using Ubuntu, my long commands only occupy 1 line. This also happens when I am going back to previous commands in the history (I hit Esc, then 'K' to go back to previous commands) - when I get to a previous command that was longer than the terminal width, the command line gets mangled and I cannot tell where I am at in the command. The only work-around I have found to see the entire long command is to hit "Esc-V", which opens up the current command in a VI editor. I don't think I have anything odd in my .bashrc file. I commented out the "set -o vi" line, and I still had the problem. I downloaded a fresh copy of Putty and didn't make any changes to the configuration - I just typed in my host name to connect, and I still have the problem, so I don't think it's anything with Putty (unless I need to make some config changes) Has anyone else had this problem, and can anyone think of how to fix it? Thanks in advance! Brian

  • Quick 2D sight area calculation algorithm?

    - by Rogach
    I have a matrix of tiles, on some of that tiles there are objects. I want to calculate which tiles are visible to player, and which are not, and I need to do it quite efficiently (so it would compute fast enough even when I have a big matrices (100x100) and lots of objects). I tried to do it with Besenham's algorithm, but it was slow. Also, it gave me some errors: ----XXX- ----X**- ----XXX- -@------ -@------ -@------ ----XXX- ----X**- ----XXX- (raw version) (Besenham) (correct, since tunnel walls are still visible at distance) (@ is the player, X is obstacle, * is invisible, - is visible) I'm sure this can be done - after all, we have NetHack, Zangband, and they all dealt with this problem somehow :) What algorithm can you recommend for this? EDIT: Definition of visible (in my opinion): tile is visible when at least a part (e.g. corner) of the tile can be connected to center of player tile with a straight line which does not intersect any of obstacles.

  • How to detect 2D line on line collision?

    - by Vish
    I'm a flash actionscript game developer who is a bit backward with mathematics, though I find physics both interesting and cool. For reference this is a similar game to the one I'm making: Untangled flash game I have made an untangled game almost to full completion of logic. But, when two lines intersect, I need those intersected or 'tangled' lines to show a different color; red. It would be really kind of you people if you could suggest an algorithm with/without math for detecting line segment collisions. I'm basically a person who likes to think 'visually' than 'arithmetically' :) P.S I'm trying to make a function as private function isIntersecting(A:Point, B:Point, C:Point, D:Point):Boolean Thanks in advance.

  • How to get working cups command line tools on Server 14.04

    - by Nick
    It looks like some of the commands like lpr and lprm have broken versions that don't work with cups. These commands worked properly on 10.04. lpr for cups has an -o option, but no lpr is intalled when cups is installed, and the lpr installed with apt-get install lpr does not have the -o option and does not appear to be the cups version of lpr. man lpr shows BSD General Commands Manual at the top, where man lpr on the Ubuntu 10.04 server said Apple, inc in the same spot. which leads me to believe the "wrong" lpr is in the "lpr" package or package names got moved around. There is also a lprng package, but trying to install it wants to remove cups and cups-client. lprm also returns lprm: PrinterName: unknown printer when PrinterName is in fact a valid printer installed with cups and does appear in lpstat -t. How do I get the proper cups versions of lpr working on Server 14.04?

  • Command line options style - POSIX or what?

    - by maaartinus
    Somewhere I saw a rant against java/javac allegedly using a mix of Windows and Unix style like java -classpath ... -ea ... Something IMHO, it is no mix, it's just like find works as well, isn't it? AFAIK, according to POSIX, the syntax should be like java --classpath ... --ea ... Something and -abcdef would mean specifying 6 short options at once. I wonder which version leads in general to less typing and less errors. I'm writing a small utility in Java and in no case I'm going to use Windows style /a /b since I'm interested primarily in Unix. What style should I choose?

  • How do I start "Ubuntu classic desktop" (no effects) from the command line

    - by Andrew Stern
    I am able to run sessions over an ssh connection but I rather use the "Ubuntu classic desktop (no effects)" version on Ubuntu 11.04 instead of the new Unity since I don't have 3d support on the laptop I'm using to display the graphical User Interface. How can I startup the older gnome-session without the 3d effects? I tried gnome-session but it seems to be the option with the 3d effects and I want a more stripped down session over my ssh session.

  • Any command line calculator for Ubuntu?

    - by AgentCool
    I am looking for a Calculator which can do calculations in the terminal itself without any other extra prefixes and suffixes. For example: If I typed something like 10000-9000 in the terminal, the answer should come out as 1000. Once again I am saying, I just need a quick calculator in terminal, without any characters added. I know if I switch to Python, it can do that but I don't want it in such a way.

  • Problem with reading file line-by-line

    - by Maulrus
    I'm trying to complete an exercise to write a program that takes the following command line arguments: an input file, an output file, and an unspecified number of words. The program is to read the contents of the input file line by line, find for each word given which lines contain the word, and print the lines with their line number to the output file. Here's my code: #include <iostream> #include <fstream> #include <string> #include <sstream> using namespace std; int main(int argc, char* argv[]) { if (argc < 4) { cerr << "Error #1: not enough arguments provided\n"; return 1; } ifstream in(argv[1]); if (!in.is_open()) { cerr << "Error #2: input file could not be opened\n"; return 2; } ofstream out(argv[2]); if (!out.is_open()) { cerr << "Error #3: output file could not be opened\n"; return 3; } ostringstream oss; for (int i = 3; i < argc; ++i) { int k = 0; string temp; oss << argv[i] << ":\n\n"; while (getline(in, temp)) { ++k; unsigned x = temp.find(argv[i]); if (x != string::npos) oss << "Line #" << k << ": " << temp << endl; } } string copy = oss.str(); out << copy; in.close(); out.close(); return 0; } If I try to run that, I get the predicted output for the first word given, but any words following it aren't found. For example, for the source code above will give the following output: in: Line #1: #include <iostream> Line #2: #include <fstream> Line #3: #include <string> Line #4: #include <sstream> Line #5: using namespace std; Line #7: int main(int argc, char* argv[]) { Line #12: ifstream in(argv[1]); Line #13: if (!in.is_open()) { Line #14: cerr << "Error #2: input file could not be opened\n"; Line #22: ostringstream oss; Line #23: string temp; Line #24: for (int i = 3; i < argc; ++i) { Line #26: int k = 0; Line #28: while (getline(in, temp)) { Line #30: unsigned x = temp.find(argv[i]); Line #31: if (x != string::npos) Line #32: oss << "Line #" << k << ": " << temp << endl; Line #35: string copy = oss.str(); Line #37: in.close(); out: That is, it'll find all the instances of the first word given but not any following. What am I doing wrong here?

  • E: Sub-process /usr/bin/dpkg returned an error code (1) seems to be choking on kde-runtime-data version issue

    - by BMT
    12.04 LTS, on a dell mini 10. Install stable until about a week ago. Updated about 1x a week, sometimes more often. Several days ago, I booted up and the system was no longer working correctly. All these symptoms occurred simultaneously: Cannot run (exit on opening, every time): Update manager, software center, ubuntuOne, libreOffice. Vinagre autostarts on boot, no explanation, not set to startup with Ubuntu. Using apt-get to fix install results in the following: maura@pandora:~$ sudo apt-get -f install Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... Done The following package was automatically installed and is no longer required: libtelepathy-farstream2 Use 'apt-get autoremove' to remove them. The following extra packages will be installed: gwibber gwibber-service kde-runtime-data software-center Suggested packages: gwibber-service-flickr gwibber-service-digg gwibber-service-statusnet gwibber-service-foursquare gwibber-service-friendfeed gwibber-service-pingfm gwibber-service-qaiku unity-lens-gwibber The following packages will be upgraded: gwibber gwibber-service kde-runtime-data software-center 4 upgraded, 0 newly installed, 0 to remove and 39 not upgraded. 20 not fully installed or removed.

  • TechEd 2010 Day Two – No SQL Server in Sight

    - by BuckWoody
    Today I worked the booth at TechEd 2010, manning the new “Surface” computer, which is just the coolest object on the planet. After that I didn’t attend a single SQL Server session – instead I’ve been frequenting SharePoint, Microsoft Office, and even the High-Performance Computing sessions. The reason is that I get really high quality SQL Server presentations at PASS, SQL Saturdays, and online from Microsoft and other vendors. While there are SQL Server sessions here (after all, I’m giving one of them!) I tend to try and see things that I don’t normally get to learn about. And the cross-pollination between those technologies and mine is fantastic.     I’ve even managed to go to an Entity Framework presentation for the developers. I actually have (a little) more respect for that technology – and I’ve modified my presentation to encompass more of that information. So whenever you have the chance, take a walk outside your comfort zone. Even at PASS and SQL Saturdays (and certainly online) you can investigate technologies other than the ones you know best.  Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • How to prevent "underwater sight" in games

    - by CPP_Person
    In many games where the player can go underwater, it seems like when you look where the top half of the screen is in the air, and the bottom half the screen is in the water, it's almost like the water doesn't exist and the player is... flying slowly with water sounds? Is there a logical way to solve this? An algorithm? Doesn't seem like any solution has come up yet since many games still have this. I don't want to make the same mistake.
