  • Creating a Custom Ubuntu Daemon

    - by Chris S
    What's the "correct" way to create a custom daemon in Ubuntu, that will start at boot time and be controllable by Ubuntu's standard daemon start/stop commands? Can I just copy and paste one of the scripts in /etc/init.d or do I need to "register" the daemon somewhere else?

  • Need some help setting up subdomains for my site

    - by KarimSaNet
    I'm setting up my website and want to have it so all subdomain requests are rewritten to the appropriate subdirectory. For example http://projects.karimsa.net/ -> http://karimsa.net/projects/ But I want to use the Apache rewrite mod to do this so that the URL in the browser stays the same. Here is what my config looks like at the moment: ## rewrite subdomains RewriteEngine On RewriteCond %{HTTP_HOST} ^(.*).karimsa.net RewriteCond %{HTTP_HOST} !^www.karimsa.net [NC] RewriteRule ^(.*)$ http://karimsa.net/%1/$1 [R=301,L] And my CNAME records on 'projects.karimsa.net': Domain TTL Data Type projects.karimsa.net 14400 karimsa.net CNAME Theoretically, I feel this should work. But when I go to the URL, it gives me a server misconfiguration error, my provider's default webpage. What I should see is the index.php under /projects/. What am I doing wrong? Any help would be appreciated, thanks for reading. Addition: I realized I forgot to mention some of the problem. The domain 'karimsa.net' is parked at 'karimsa.x10.mx'. If I set up the same configuration on 'projects.karimsa.x10.mx', the rewrite and CNAME work. But on the parked domain I still get the default webpage.

  • php cURL problem

    - by dfilkovi
    I have a problem logging onto a page and then using it with cURL. I login, get PHPSESSID and cookie, and then try to do an action but page returns 'not logged in'. But if I manually log in and copy/paste that PHPSESSID into curl cookies .txt file, everything works fine. So why doesn't it work with PHPSESSID from cURL?

  • check if foler exists in the root jquery

    - by Dimal Chandrasiri
    I'm trying to load an image to a div background using the following file structure in the root. WebContent -- | zharaimages -- | [ItemID] -- | Image.jpg This is done by jQuery and the file structure is inside the root. The ItemID folder is dynamic and I have to check whether the path exists using jQuery and if the path is not valid, I should go to a default path to fetch the default image. How can I check the path is valid using jQuery. I'm hoping to this can be done without an ajax call. Can any one help me on a tutorial or an API I can use for this! UPDATE The files are on the server. The concept I have is that I have 100s of item elements & I want to load an image for each item element. The images are saved in the server ( a local host ) and the folder hierarchy is divided using the item ID as shown. What I want to do is check whether the image file exists before appending it to the background of the item element div. Is this possible. This is a web application developed using spring.

  • linux process scheduling delayed for long time

    - by Medicine
    I have done strace on my multi-threaded c++ application running on linux after couple hours of running, none of the threads got run, for about 12 seconds. I have seen that the unfinished select system call which is called with a timeout was unfinished before the thread was suspended, reported after it resumed that, it took 11.x seconds for the operation to finish. This is clear indication that the process got starved for a long time. All threads in the process are created with default scheduling policy(SCHED_OTHER) of linux and default priority. There are another 5 similar apps running on the same box which are also heavy I/O bound like this app due to heavy data received on the socket. But most of the time, this app is getting scheduled delay. The other apps are created with same sched policy and priority as this i.e. the defaults. why is only this process gets blocked almost all of the time? Could it be because this process is more I/O intensive as in more busy due to may be higher rates of data? So, the linux dynamic priority adjusting in play here which pushed this process down?

  • how to compare dll files

    - by queandans
    I have a post-build script after building my c# project that will place one of the dll files in a specific directory. This dll is saved in SVN. My question is, is there a way that when building my project, it knows that this dll has not changed and would know not to be copied over to the directory so the there will not be a modified copy for the SVN?

  • Call to a member function ... on a non-object

    - by jayceekay
    i have an object which is instantiated in an initialize file, which is called with every request. the name is right, so why is it telling me that oourls isn't an object and that redirectLoggedIn isn't its method? a var dump on oourls says NULL. but it's instantiated, and the backtrace at the bottom shows that it goes through initialization and instantiates it. pretty small snippet of code, here's the relevant bit: if($email) { global $session; $session->grantLogin($email); global $oourls; $oourls->redirectLoggedIn(); } else { return false; } and here's the output of debug_print_backtrace i threw in above the oourls method call because i'm completely confused: #0 accounts::verifyEmailRegisterAccount(37a6274c8f4bfa5c537b40e8e04d634a) called at [\public\includes\default\verifyemail.php:16] #1 require_once(\public\includes\default\verifyemail.php) called at [\support\php\ObjectOrientedURLs.class.php:48] #2 ObjectOrientedURLs->mhqqrVerifyemail(Array ([0] => 37a6274c8f4bfa5c537b40e8e04d634a)) #3 ReflectionMethod->invoke(ObjectOrientedURLs Object (), Array ([0] => 37a6274c8f4bfa5c537b40e8e04d634a)) called at [\support\php\ObjectOrientedURLs.class.php:280] #4 ObjectOrientedURLs->parseAndInvokeURL() called at [\support\php\ObjectOrientedURLs.class.php:255] #5 ObjectOrientedURLs->__construct() called at [\support\php\initialize.php:76] #6 require_once(\support\php\initialize.php) called at [\public\index.php:2]

  • git recognizes directory as file

    - by dbarrera
    A recent issue has arised. I have my local copy of code at ~/code/ directory where I made a git init. Whenever I copied a folder with files within it, git recognized folders and files normally. But today I copied a folder and when I did a git status, git recognized hw2/ folder as a file. Additionally, I removed .git folder and reinitialized git and now every folder is recognized as file. Any ideas why this could be?

  • .Net file writing and string splitting issues

    - by sagar
    I have a requirement where the file should be split using a given character. Default splitting options are CRLF and LF In both these cases I am splitting the line by \r\n and \r respectively. Also I have requirement where any size of file should be processed. (Processing is basically inserting the given string in a file at given position). For this I am reading the file in chunk of 1024 bytes. Then I am applying the string.Split() method. Split() method gives options for ignoring white spaces and none. I have to add back these line break characters to the line. for this I am using a binary writer and I am writing the byte array to the new file. Issue:- 1) When line break is CRLF, and the split option is NONE, while spaces are also added in the splitted array. Second option is given (to ignore white spaces) CRLF works properly. 2)Bit ignoring white space option creates other problems, as I am reading the file byte by byte I can't ignore a white space. 3)When line break characters are other than default(e.g. '|', a null value is prepended to the resulting line. Can anybody give solution to my issues?
