  • how install minimum domain email piping to script in centos?

    - by Adam Ramadhan
    hello i have search google on a simple tutorial on how to make a piping email. first how does really email technically work? "stmp is a process that binds to 25, waiting for email request that goes in from another stmp process(in another server) determined by the domain MX route that will send the message to port 25 if any email goes though the MX.domain.tld" that is in a nutshell how emailing work, am i right? or there is something wrong here? second, so if im right, we need to set a SMTP server so we can receive incoming emails from MX SMTP route right? ive googled though google and found two best STMP servers from my opinion, they are EXIM and POSTFIX, can anybody give us a simple tutorial installing and setting up an email piping for a fresh installed linux/centos? example *.domain.tld -> allinonepipe.php thanks.

  • Change a Recursive function that has a for loop in it into an iterative function?

    - by Bill
    So I have this function that I'm trying to convert from a recursive algorithm to an iterative algorithm. I'm not even sure if I have the right subproblems but this seems to determined what I need in the correct way, but recursion can't be used you need to use dynamic programming so I need to change it to iterative bottom up or top down dynamic programming. The basic recursive function looks like this: Recursion(i,j) { if(i>j) return 0; else { //This finds the maximum value for all possible subproblems and returns that for this problem for(int x = i; x < j; x++) { if(some subsection i to x plus recursion(x+1,j) is > current max) max = some subsection i to x plus recursion(x+1,j) } } } This is the general idea, but since recursions typically don't have for loops in them I'm not sure exactly how I would convert this to iterative. Does anyone have any ideas?

  • How practical to change MVC app from traditional authentication to cookieless?

    - by Phil.Wheeler
    I have an application written in MVC that uses your regular .Net Forms Authentication. There's nothing particularly new or exciting going on with it. My client has now asked that users be able to log in to the app on the same machine but in different browsers, or different tabs within the same browser. To my mind, he's asking for a scope change to have authentication moved to cookieless instead of its current design. Not having had any experience with doing this in MVC, I'm curious to know before I get started how much hurt I'm in for by trying this. Are there better ways to do it? What should I consider? Any advice appreciated.

  • How to deal with files that are relevant to version control, but that frequently change in irrelevant ways?

    - by Jens Mühlenhoff
    .dproj files are essential for Delphi projects, so they have to be under version control. These files are controlled by the IDE and also contain some information that is frequently changed, but totally irrelevant for version control. For example: I change the start parameters of the application frequently (several times a day), but don't want to accidently commit the project file if only the part dealing with the start parameters has changed. So how to deal with this situation? A clean solution would be to take the file apart, but that isn't possible with the Delphi IDE AFAIK. Can you ignore a specific part of a file? We're using Subversion at the moment, but may migrate to Git soon.

  • How do I change the console resolution of Ubuntu 9.10 Server running on VMWare?

    - by Raam Dev
    I'm running Ubuntu 9.10 Server in VMWare Fusion (on a Mac) and I'm having trouble changing the console resolution. It seems to be stuck on 640x480. Ubuntu 9.10 uses Grub2, so there is no /etc/grub/menu.lst. I tried adding vga=791 to the kernel parameters (both during boot and by adding it to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and then running update-grub2) and neither had any effect. When using vga=791, grub says that vga=791 is depreciated and that I should use gfxpayload=1024x768x16,1024x768 instead. However, that also does absolutely nothing. I have a feeling this problem is specific to running Ubuntu 9.10 in VMWare, but Google hasn't turned up anything.

  • Is it possible to specify Jquery File Upload to post back only once (for multiple files)?

  • How can I change the subject of messages on an Exchange server automatically?

    - by Chris R
    I want to do something more than just normal mail - folder rules; I want to put a layer in front of my exchange server that lets me, for example, rewrite subjects into a more readable form. I get automated messages whose subject format makes them almost useless. Changing the emitting software is not going to happen, so I need to do something client side. I'm interested in anything that would allow me to do this, either on a mac, or on an older linux distro. Preferably the latter, and preferably in a way that I can turn on and forget about.

  • jQuery + External javascript: How to embed videoplayer in div

    - by Dennis
    I just started with jQuery and so far I have a really good impression of the framework. But now I have a problem that I can't figure out on myself. I want to embed an external javascript file that loads a videoplayer and displays it. If I include the <script>...</script> directly in HTML it loads just fine. But when I try to load it with jQuery it has very different behaviors in several browsers but it doesn't work in a single one. Either the player is not loaded at all or it doesn't update the selected div but reloads the player on a blank page. This is the source: <html> <head> <style type="text/css"> div#test { width: 100%; height: 500px; margin: 10px auto; padding: 5px; border: 1px solid #777; background-color: #fbca93; text-align: center; } </style> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script> $(document).ready(function(){ var video = "<script type=\'text\/javascript\' src=\'http:\/\/www.physicalfitnet.com\/video_syndication\/embed\/jssingle.aspx?vid=651&pub=9DF8233261D101B86368400385B8FF2E\'><\/script>"; $("div#test").html(video); }); </script> </head> <body> <div id="test"> Hi</div> </body> </html> I uploaded everything to http://kernast.de/test ... any help is appreciated.

  • How can I change the flow through this PAM (programmable authentication module) file?

    - by Jamie
    I'd like the PAM module to skip the pam_mount.so line when a unix login succeeds. I've tried various things including: auth [success=2 default=ignore] pam_unix.so nullok_secure auth [success=2 default=ignore] pam_winbind.so krb5_auth krb5_ccache_type=FILE cached_login try_first_pass auth requisite pam_deny.so auth requisite pam_permit.so auth required pam_permit.so auth optional pam_mount.so But can't get it to work. Conversely, when a session shuts down, how can I modify the following os that an unmount command (via pam_mount.so) is avoided during a unix login? session [default=1] pam_permit.so session requisite pam_deny.so session required pam_permit.so session required pam_unix.so session optional pam_winbind.so session optional pam_mount.so

  • Can you catch exceeded allocated memory error before it kills the script?

    - by kristovaher
    The thing is that I want to catch memory problems before they happen. I have a system that gets rows from database and casts the returned associative array to a variable, but I never know what the size of the database result is is or how much memory it will take once the database request is made. This means that my software can fail simply because memory is exceeded. But I want to avoid that somehow. One of the ways is to obviously make database requests that are smaller, but what if this is not possible or what if I do not know the size of data that is returned from database? Is it possible to 'catch' situations where memory use is exceeded in PHP? Something like this: $requestOk=memory_test(function(){ return doSomething(); }); if($requestOk){ // Memory seems fine // $requestOk now has the value from memory_test() function } else { // Function would have exceeded memory } I just find it problematic that my script can just die at any moment because of memory issues. From what I know, try-catch cannot be used here because it is a fatal error. Any help would be appreciated!

  • How to notify table-data change to a client program?

    - by JMSA
    Suppose I have an application that access data resident in a central DB server and more than one user access data from client machines networked with the DB server. Suppose two client machines are running a copy of the application and two users are accessing the same DB table. How can I automatically refresh the data on the GUI, that is being viewed by one client, as soon as a change is made by another client in the DB table-data? Which technology should be used to solve this particular scenario in .net? WCF?

  • Change ownership of directory and all contents to a new user from root.

    - by Andrew Fashion
    I created a website under /var/www/html/ all under root, all images, files, .htacess, directories, etc... I uploaded and configured everything as root.

There is also about 30GB of images in the folder as well. How can I go about changing all of this? I am running CentOS 5.5 64 bit. Thank you!

  • jquery touch punch - draggable on ipad

    - by dshuta
    i am starting to work with the jquery touch punch extensions in order to allow draggability on ipad, but i am getting tripped up right away. probably something terribly dumb on my part. the draggable example from the developer works fine on my ipad: http://furf.com/exp/touch-punch/draggable.html but not for me: http://danshuta.com/touchpunch/ this works fine in my desktop browser, but on the ipad it just focuses on the block and scrolls the entire page as i drag, as if it were just an image or other normal embedded object. as this is what happens normally with jquery/ui on ipad, this makes me think it is not loading or otherwise ignoring the "punch" code from my site (though if i host the jquery files on my site via the same path, those load and function fine in desktop browser). here's the entire code, very basic: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>Touchpunchtest</title> <script src="http://code.jquery.com/jquery.min.js"></script> <script src="http://code.jquery.com/ui/1.8.17/jquery-ui.min.js"></script> <script src="js/jquery.ui.touch-punch.js"></script> </head> <body> <div id="draggybox" onclick="void(0)" style="width: 150px; height: 150px; background: green;"></div> <script>$('#draggybox').draggable();</script> </body> </html> what am i missing?!

  • How to inject php code from database into php script ?

    - by luxquarta
    I want to store php code inside my database and then use it into my script. class A { public function getName() { return "lux"; } } // instantiates a new A $a = new A(); Inside my database there is data like "hello {$a->getName()}, how are you ?" In my php code I load the data into a variable $string $string = load_data_from_db(); echo $string; // echoes hello {$a->getName()}, how are you ? So now $string contains "hello {$a-getName()}, how are you ?" {$a-getName()} still being un-interpretated Question: I can't find how to write the rest of the code so that {$a-getName()} gets interpretated "into hello lux, how are you". Can someone help ? $new_string = ?????? echo $new_string; //echoes hello lux, how are you ? Is there a solution with eval() ? (please no debate about evil eval ;)) Or any other solution ?

  • How to change the default Help browser for VS2010?

    - by Scott Bilas
    Visual Studio 2010 changed the help system to run a little daemon and launch the system default web browser to view it. I'm using Firefox for my system browser but would like to use Chrome for VS help. Is there an option to change the Help browser that I'm not seeing in Tools|Options? If not, is there a workaround or registry setting to do this? As a backup I've been using H3Viewer but I'd like to be able to get context-sensitive F1 help from within the VS IDE.

I found instructions for TFS 2008 saying to use TFSAdminUtil ActivateAT , but this tool has now been replaced by TFSConfig and I can't see an obvious replacement for 'ActivateAT'. Any ideas what the new command should be?

  • How to change the mail domain server so it's not displaying IP? Changing [email protected] to [email protected]

  • change the return of to_param by action? or, terribly broken edit action if perma-url is returned in

    - by Stacia
    I did some stuff to have to_param return a perma-url so I'd have seo friendly links. Upon creation and update it will generate and return the perma-url in a to_param method that I put in the model. However this causing me some grief in other areas. I have a form that looks like this: <% @apps.each do |app| %> <% fields_for "[id][]", app do |fields| %> .... this fails terribly since it tries to insert the perma-url in place of the id. If I could just restrict to_param by action, that could solve things. If I change app to app.id, that fails since I have stuff like this: fields.check_box :is_featured . I suppose I could get the app instance, but that feels hacky. Again please excuse my lack of rails-foo ;)

  • How to change the coordinate of a point that is inside a GraphicsPath?

    - by Ben
    Is there anyway to change the coordinates of some of the points within a GraphicsPath object while leaving the other points where they are? The GraphicsPath object that gets passed into my method will contain a mixture of polygons and lines. My method would want to look something like: void UpdateGraphicsPath(GraphicsPath gPath, RectangleF regionToBeChanged, PointF delta) { // Find the points in gPath that are inside regionToBeChanged // and move them by delta. // gPath.PathPoints[i].X += delta.X; // Compiles but doesn't work } GraphicsPath.PathPoints seems to be readonly, so does GraphicsPath.PathData.Points. So I am wondering if this is even possible. Perhaps generating a new GraphicsPath object with an updated set of points? How can I know if a point is part of a line or a polygon? If anyone has any suggestions then I would be grateful.
