  • C++ domain specific embedded language operators

    - by aaa
    hi. In numerical oriented languages (Matlab, Fortran) range operator and semantics is very handy when working with multidimensional data. For example: A(i:j,k,:n) // represents two-dimensional slice B(i:j,0:n) of A at index k unfortunately C++ does not have range operator (:). of course it can be emulated using range/slice functor, but semantics is less clean than Matlab. I am prototyping matrix/tensor domain language in C++ and am wondering if there any options to reproduce range operator. I still would like to rely on C++/prprocessor framework exclusively. So far I have looked through boost wave which might be an suitable option. is there any other means to introduce new operators to C++ DSL?

  • Can't install software from Ubuntu software center

    - by Casbar
    I've been experimenting with Ubuntu 10.04(64bit) inside a VirtualBox VM. This isn't my first experience with Linux, but I'm still very much a Linux noob. Whenever I try to install software from the Ubuntu Software Center, the installation gets interrupted and I get a warning that this installation requires untrusted sources. I can install anything I want using apt-get, it's just the gui that doesn't work. I've done research on the issue and taken the following precautions with no result: under software sources Allowed Canonical partners Allowed source code Changed the download source to main server I get no errors when running an apt-get update. Can anyone shed some light on the issue?

  • Does there exist video chat software which works over a LAN between different types of devices?

    - by Graphics Noob
    What I'm trying to do is set up a local area network, without internet access, which allows the users to video chat with each other. The connected devices will include Linux and Android devices, so software which will run with just those two types of systems will work, although running through a browser would be optimal. The most promising lead I've found so far is camfrog, which has a video-chat app for android and a video chat server for linux. The problem is that the documentation for the server is non-existant, and I don't know if the android app can directly connect to the video chat server over a LAN or if it can only connect to camfrog's video chat server over the internet.

  • X server not starting up after new kernel compilation

    - by tech_learner
    I have compiled the Kernel on my 64-bit Debian XPS Studio 1340 Dell system. srikanth@debian:~ - 05:40:52 PM - $ uname -a Linux debian 2.6.32-5-amd64 #1 SMP Thu Mar 22 17:26:33 UTC 2012 x86_64 GNU/Linux Kernel version that I have used and compiled from kernel.org is 2.6.35.13 I have nvidia installed on old kernel. I got the old config and I used the same config to compile the new kernel. Everything went well and I got two debian packages ( image and headers ) which I have installed on my system. When I select the new kernel on the boot menu and I go into it, the X server is not starting up possibly because I have to "rebuild" ( not sure how to do that ) according to this link: http://www.linuxquestions.org/questions/slackware-14/x-server-not-starting-after-kernel-compilation-605265/ Can you suggest how to do the rebuild on nvidia module so that I can start x ( without seeing any blank screen or error saying nvidia module is missing ) ? PS: The link that I have used to compile the kernel is https://help.ubuntu.com/community/Kernel/Compile#Alternate_Build_Method:_The_Old-Fashioned_Debian_Way

  • Excel embedded in a php page

    - by Brian
    I have a client who wants to be able to embed an Excel document (one that is currently sitting on the same server as the HTML document) like how you would embed a Flash app on a page. I'm correct in assuming this is not possible, right? Please confirm/deny so we can hopefully move on from this because he seems to think this is possible. We are on a LAMP setup so no .NET tricks, unfortunately.

  • Compress a directory in linux

    - by user9589
    I'm trying to compress a directory and ftp it to a windows ftp. I have tried ever tar command i can find to compress a directory. It appears to be ok then I try and view it's contents using winrar. Winrar keeps telling me the file is corrupt. I have viewed other .gz or .bz2 files using winrar but for some odd reason I can't get it to work. Does anyone else have a suggestion as to something else to try. I would prefer just to have it zip the files so they have a .zip extension but even then when i try to browse it's contents both windows and winrar claim it's corrupt.

  • Kill xserver from command line (init 3/5 does not work)

    - by Richard Martinez
    I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail. The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. Note: If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?

  • MVC 4 iframe embedded in desktop page showing mobile view

    - by Reto Laemmler
    I use Index.cshtml and Index.mobile.cshtml. My Index.cshtml is a mobile app landing page containing an iframe to live demo the mobile web app. Index.mobile.cshtml is the mobile web app itself. The problem is, the iframe keeps loading the desktop version itself. As far as I know, I cannot configure the user agent of the iframe to a mobile type. It should be solvable with some routing but I couldn't figure out how!?

  • NIS AD password synch for new accounts

    - by user135004
    I have a Win2k3R2 DC with NIS. All is working well but its no longer synching the passwords for new accounts. When creating a new AD user, NIS does its thing and sends its Unix account to the synched linux server. It's doing everything its supposed to do but not the users password to the server (getent passwd returns the ABCD!efgh12345$67890 password for the new account). Thinking that password synchronization is not working, I changed the password of an existing working account and it synchs the new password. If I delete a new or old AD user, it deletes it on the linked linux server as well. All this tells me that NIS is doing its thing (at least with existing accounts) No updates have been installed on the DC. I am not even sure where to start here.

  • I'll be setting up a dedicated web server at work soon, my first non hobby server - What should I know?

    - by Rogue Coder
    I've been running my own dedicated server running CentOS and a LAMP stack for 2-3 years now, but it's only been hosting my own websites which aren't super important. However, I will soon be setting up a Linux Webserver and Linux Database Server at work, and I'm wondering what are some important things I should be doing. It's an internal server only, so only people in the company can access it. Should I get a slave server for both of my servers for backups? If I do this, how many backups should I be keeping and how often should those backups be done? Right now on my current server I run a cron job nightly to backup my MySQL databases (Usually 40mb files once compressed), and bi-weekly cron jobs to backup my web root. I just store these files on my local computer via FTP. Also, for an internal server like this, should I look at using LightHTTPD or NginX to increase performance, or will Apache be fine?

  • .NET make a copy of an embedded file resource to the local drive

    - by Matt H.
    Hi, i'm new to the realm to working with Files in .NET I'm creating a WPF application in VB.NET with the 3.5 Framework. (If you provide an example in C#, that's perfectly fine.) In my project I have a Template for an MS Access database. My desired behavior is that when the users clicks File--New, they can create a new copy of this template, give it a filename, and save it to their local directory. The database already has the tables and some starting data needed to interface with my application (a user-friendly data editor) I'm thinking the approach is to include this "template.accdb" file as a resource in the project, and write it to a file somehow at runtime? Any guidance will be very, very appreciated. Thanks!

  • Mounting Wubi part from another Linux installation

    - by FrankSus
    hope someone can help. I need to access 11.04 ubuntu files residing on a second hard drive (dual boot XP/Ubuntu) from a 10.04 hard drive installation. The 11.04 system co-exists with XP on the second drive. This drive is HPFS/NTFS. My 10.04 installation mounts and displays the contents of the XP installation and all files but the 11.04 system is nowhere to be seen. How can I see and access the Ubuntu partition, please?
