  • Processes sharing cores on Ubuntu system

    - by muckabout
    My coworkers and I share an 8-core server running Ubuntu for our batch processes. I tend to run 4 processes at a time, each of which consumes 100% CPU per core when nothing else is running. When a coworker runs his processes (typically about 4 at a time), his also get 100% per. However, when both of us run ours (he always goes first), his still get 100% and mine seem to divide the remaining processing power and linger in the 10-40% range. I even reniced his process to a lower value and it did not change. What are the issues that may cause this?

  • Ubuntu Eye-Infinity across 3 displays

    - by Peter G Mac.
    So I purchased a computer recently and have been trying to customise the display. Radeon 6800 series Ubuntu 10.10 I have three 22inch 1080P lcd monitors that are mounted together. Everything is working smooth. How do I get the 'big-desktop' display where I have one enormous display across all monitors? Linux - ATI Catalyst Control Center 11.2 does not give me an option to 'group' my profiles like the pictures on their site show with Windows. I have been searching all over for help. Much Obliged, -Peter

  • Set environment variable in Ubuntu

    - by Junho Park
    In Ubuntu, I'd like to switch my JAVA_HOME environment variable back and forth between Java 5 and 6. I open a terminal and type in the following to set the JAVA_HOME environment variable: export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun And in that same terminal window, I type the following to check that the environment variable has been updated: echo $JAVA_HOME And I see /usr/lib/jvm/java-1.5.0-sun which is what I'm expecting to see. In addition, I modify ~/.profile and set the JAVA_HOME environment variable to /usr/lib/jvm/java-1.5.0-sun. And now for the problem--when I open a new terminal window and I check my JAVA_HOME environment variable by typing in echo $JAVA_HOME I see that my JAVA_HOME environment variable has been reverted back to Java 6. When I reboot my machine (or log out and back in, I suppose) the JAVA_HOME environment variable is set to Java 5 (presumably because of the modification I made in my ~/.profile). Is there a way around this so that I can change my JAVA_HOME environment without having to log out and back in (AND make that environment variable change stick in all new terminal windows)?

  • User defined literal arguments are not constexpr?

    - by Pubby
    I'm testing out user defined literals. I want to make _fac return the factorial of the number. Having it call a constexpr function works, however it doesn't let me do it with templates as the compiler complains that the arguments are not and cannot be constexpr. I'm confused by this - aren't literals constant expressions? The 5 in 5_fac is always a literal that can be evaluated during compile time, so why can't I use it as such? First method: constexpr int factorial_function(int x) { return (x > 0) ? x * factorial_function(x - 1) : 1; } constexpr int operator "" _fac(unsigned long long x) { return factorial_function(x); // this works } Second method: template <int N> struct factorial { static const unsigned int value = N * factorial<N - 1>::value; }; template <> struct factorial<0> { static const unsigned int value = 1; }; constexpr int operator "" _fac(unsigned long long x) { return factorial_template<x>::value; // doesn't work - x is not a constexpr }

  • PHP is_file returns false (incorrectly) for Windows share on Ubuntu

    - by M3Mania
    Ubuntu server, PHP 5.3, connected via Samba to Windows server share. I am using file_exists() to check for availability of file on Windows machine. It returns false, although the filepath does exist. Meanwhile, file_get_contents() on the exact same filepath works fine. I'm wondering if it's a permission issue, since I'm having trouble configuring permissions of the files on the Windows share (it says I don't have permission to change permissions on them). When I look at the permissions through Nautilus, it says the user and group are both root, with 755 rights. I'd like to change the group to www-data, but can't seem to do it.

  • Mono 2.10.5 Runtime error on Ubuntu 11.10

    - by johnluetke
    I've install mono-runtime via apt in order to run my Mono console application on Ubuntu via SSH. However, when I run the command mono myapp.exe, It exits, with no message, and my program does nothing. If I throw the -v switch to Mono, such as mono -v myapp.exe, I get about 10k lines of output (as expected, -v is verbose), with the first few lines being: converting method System.OutOfMemoryException:.ctor (string) Method System.OutOfMemoryException:.ctor (string) emitted at 0xb7052c28 to 0xb7052c4b (code length 35) [myapp.exe] converting method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) Method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) emitted at 0xb7052c68 to 0xb7052cf6 (code length 142) [myapp.exe] converting method System.SystemException:.ctor (string) I read this as the runtime throwing an OutOfMemory exception, but the machine is under no intense load, has plenty of available RAM, and is running nothing other that system processes. I've removed and reinstalled Mono countless times, and have even run the executable on other machines perfectly fine. Am I missing something completely obvious here?

  • JRI Fatal Error on Ubuntu

    - by Peter Jackson
    I have successfully installed JRI and rJava on Windows 7. I am now trying to get it to work on Ubuntu with 64bit OS. I can make rJava calls from within R but getting JRI to work is more difficult. I am running NetBeans 7.1.2 and I have followed various tricks in setting R_HOME and java.library.path to enable all the classes to be loaded. That is, I am past the error messages such as "jri library not found" and "R_HOME not set". From my java code,I can see that R_HOME = /usr/lib64/R. The error message I get now is Fatal error: you must specify '--save', '--no-save' or '--vanilla' This happens when Rengine is first called: Rengine r = new Rengine(args,false,null); This appears to be an error message from R; it seems to be expecting a command line argument. I haven't seen any posting with this error message. Any ideas? Thanks, Peter

  • What library to choose to build a user interface for a C++ software that uses SDL

    - by Barth
    Dear all, I have a simulation software (C++) that runs on the command line. It is platform independent (currently compiling and running on Windows, MacOS X and Linux). When the simulation ends, I visualize the result with SDL; it is a very basic 2d view, mainly color squares next to each other. I would like to have a user interface on top of the simulation so that I can start and pause the simulation, and change the parameters on the fly. Something pretty simple I guess. Well, ideally I will also add a grapher somewhere to see the evolution over time of some parameters. Now, I am wondering what direction I should go. Should I try to use one of the UI libraries for SDL ? Or maybe wxwidget in conjunction with SDL ? Or simply wxwidget and get rid of SDL ? Do you have any experience with this ? Thanks in advance Barth PS: I tried to use AGAR, a SDL UI library. It seemed very promising but I couldn't get it working. Not even the helloworld.

  • [C#] Dynamic user-interface, WPF or not?

    - by pieter.lowie
    Hi, I'm currently working at a application that helps people understand how to do there job. You can see it as a personal coach that guides them trough all the steps they need to do that no normal person could keep remembering. In my previous application we had the ability to show the user up to 4 pictures (what proves to be more then enough). The application would load the data and see how many pictures where in every instruction and then sort out the picture in the best fitting way without messing up the scale and resolution of the pictures. This all was done with GDI+ and worked very well. Ofc, change is something that always happens, my bosses came up with some great ideas. So they want to be able to see movies on the screen, animated gif's, 3D models that can rotate or animate. So I think we had pushed GDI+ to it's limits and it's time to look for something different. I have heard and readed about WPF but have no experience with it. Is it even possible to do all what I ask in WPF? And what about the old picture-merging thing I wrote, can we also get it done in wpf? I tried to make some things working but I didn't went as smooth as I hoped. I'm also concerned about the fact that the interface needs to be dynamic, the one moment it should be showing picture with some text above it, the other moment it should be showing another text with a video under it. I would love to hear some opinions here and if you got some other suggestions I should look into pls tell me. Thnx in advance PS: If WPF is the choice, should I convince my boss to change to .net 4.0?

  • Ubuntu makes noise and heat when AC charger is inserted

    - by user2263752
    I have an issue with heat and noise on my laptop with Ubuntu 14.04 installed. The thing is that when I have the AC charger plugged into the laptop, it automatically goes to "boost mode" or something. And when the laptop is on battery mode, the heat and noise is reduced shortly. I want the laptop to be on battery mode as general and "boost mode" as an option if more power is needed. Any solutions? I have installed tlp that doesn't seen to have any effect.

  • Bash script with regex not behaving on Ubuntu

    - by user265330
    I have a Bash script that is working on my OpenSuSE box, but when copied across to my Ubuntu box, is not working. The script reads in from a file. The file has fields separated by white space (tabs and spaces). #!/bin/bash function test1() { while read LINE do if [[ $LINE =~ "^$" || $LINE =~ "^#.*" ]] ; then continue; fi set -- $LINE local field1=$1 local field2=$2 done < test.file } test1 with test.file containing: # Field1Header Field2Header abcdef A-2 ghijkl B-3 There seem to be two problems: (1) $field2, the one with the hyphen, is blank (2) The regex to strip out the blank lines and lines that start with # is not working Anyone know what's wrong? As I said, it works fine on OpenSuSE. Thanks, Paul

  • mCrypt not present after Ubuntu upgrade to 13.10

    - by VukBG
    After I have upgraded my system from Ubuntu 13.04 to 13.10 several problems have occurred with apache, mysql and php configurations. I solved most of them but I can't seem to get mCrypt library working. Package is installed so i don't need to apt-get it. Server works and everything seems fine, but when I try to run php artisan serve with Laravel 4, I get a message that mCrypt is required. I did php --ri mcrypt and the output was Extension 'mcrypt' not present. I have tried putting extension=mcrypt.so to /etc/php5/apache2/php.ini but it didn't worked. Any ideas?

  • Apache2 on Ubuntu Server w/ CGI, FastCGI, mod_php

    - by illegal3alien
    I've looked at various websites on configuring Apache with cgi and can't get mod_fcgid to work. It works fine using mod_php5, but I wanted to compare performance using cgi and fastcgi. I tried methods using FGCIWrapper among various other techniques and the only one that didn't result in an unlogged 403 or download of the file was using "Action application/x-httpd-php /usr/bin/php-cgi" When trying to configure mod_fcgid the file normally just started a download of an unprocessed file. I used wget to check headers and type was "application/x-httpd-php" At one point I was able to get to the page, but it resulted in a 403, which was listed in access.log, but not error.log (I was told it should be in there too) I tried to get it working on a fresh install of Ubuntu Server 10.04 LTS and 10.10 and had the same results on both, so I'm not doing something correctly in terms of configuration. I tried virtualmin and could only get mod_php to work. The page just prompted a download when selecting cgi or fcgi from the control panel.

  • How can I simplify this user interface?

    - by Bears will eat you
    I'm writing an internal-tools webapp; one of the central pages in this tool has a whole bunch of related commands the user can execute by clicking one of a number of buttons on the page, like this: Ideally, all of the buttons would fit on one line. Ordinarily I'd do this by changing each widget from a button with a (sometimes long) text label to a simple, compact icon - e.g. could be replaced by a familiar disk icon: Unfortunately, I don't think I can do this for every button on this particular page. Some of the command buttons just don't have good visual analogs - "VDS List". Or, if I needed to add another button in the future for some other kind of list, I'd need two icons that both communicate "list-ness" and which list. So, I'm still considering this option, but I don't love it. So it's come time for me to add yet another button to this section (don't you love internal tools?). There's not enough room on that single line to fit the new button. Aside from the icon solution I already mentioned, what would be a good* way to simplify/declutter/reduce or otherwise improve this UI? *As per Jakob Nielsen's article, I'd like to think that a dropdown menu is not the solution.

  • Android API Target Level 5 and 6 for Ubuntu

    - by Sebi
    Today i installed Ubuntu 10.4 and Eclipse Galileo. Then I downloaded the Android SDK and tried to install all packages via the Android SDK Tools. But unfortunately, only the Target Levels 3, 4, 7 and 8 were available. API Level 5 and 6 are missing. Does anybody know the reason for this? I already did a Google search and there seems to be nobody with the same problem. I also tried to restart it and nothing happens, the API Levels are still missing.

  • Why doesn't the Ubuntu Installer see all of my hard drives

    - by atodd
    I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed. I've tried everything I know. I'm not sure if its a BIOS setting or something else I've missed.

  • How to install Revolution R Enterprise?

    - by Abe
    Revolution R Enterprise is available as a red-hat rpm file. Normally I would use alien to install an rpm file, but the instructions for installing this package have an install.py file that I am supposed to execute. When I ./install.py, I get the following instructions: rpm: please use alien to install rpm packages on Debian, if you are really sure use --force-debian switch. See README.Debian for more details. There is no README.Debian file in the directory, and although I am not proficient in python, I can tell that there are at least four different directories with *rpm files in them. Has anyone had success with this? If possible, I'd prefer to install the Enterprise version instead of community version in the Ubuntu repository so that I can test it out.

  • Rhythmbox not saving the album art permanently

    - by Nik
    I run ubuntu 10.10 and use rhythmbox (version 0.13.1) regularly with the albumartsearch plugin installed. However when I change the album art it is only temporary. On moving to the next song it automatically removes the previous song's album art cover. (I do know about banshee but would like to use rhythmbox). The cover art plugin is also installed by default however it cannot display some of the album covers since the songs are in my local language (tamil) hence it cannot retrieve the album cover from the internet. However the albumartsearch plugin seems to do the job although only temporarily. Any reason why it might be? I have tried looking for other rhythmbox plugins which might be similar to albumartsearch but in vain. Any help would be appreciated. I have filed a bug in the albumartsearch plugin's website. Waiting for the reply.

  • Brightness keys adjust brightness too many times

    - by erjiang
    Every time I hit a brightness key on my laptop's keyboard, it adjusts the brightness by three steps instead of one. How can I fix it so that it only adjusts one step at a time? I am using an Acer Aspire D250 with the newest firmware. It was working better when I was using Ubuntu 10.10 with older firmware (although the scale was off). Any tips on debugging this would be appreciated.

  • No wireless and display issues on Dell Inspiron 1210 (Mini 12)

    - by Bryan M.
    I recently upgraded a friend's Dell Mini 12 (Inspiron 1210) from Ubuntu 8.10 to 10.04 netbook edition. After installing, and performing the available updates, I'm unable to detect any wireless networks (it knows it has a wireless card, but won't list any active networks). There also seems to be an issue with the display drivers: when scrolling, resizing, or drawing any windows there is a noticeable lag as I watch the screen redraw. As if there are no compatible display drivers installed. All these problems go away the moment I boot up a version of 8.10. But I'd like to keep 10.04 if possible. Are these common problems? Everything I've read suggest this is laptop should be compatible. Any suggestions? Thanks.

  • Application to display battery info

    - by Nik
    First of all, I am not sure the title of this question is the most appropriate however this is what I meant to say, There are many ways to extend the life of a laptop battery. One way is by not connecting it to the AC adapter all the time which will overcharge it. I read that in this website. Is there an application which automatically prevents the charging of the battery once it has reached 80% charged? I mean that is such a cool feature. Sometimes people tend to forget to remove the AC adapter and this could diminish the capacity and reduce the life time of the battery. Does the battery indicator in ubuntu display info or pop-up when the battery is almost dead (dead not in the sense of usage time) but rather a degraded battery?
