  • Flipping an image using a one dimensional array of characters.

    - by Jeff
    I have the data of an image loaded into memory as a one dimensional array. Since I'm trying to use OpenGL to draw it, and since it reads from the bottom up, I want to try and flip the elements of the array before they're sent to OpenGL. Maybe there's a way to tell OpenGL to read from the top to the bottom? Anyways, I tried using a few methods of sorting arrays and they also flip the image horizontally, which is very much like the original problem. So can I flip the data only one way?

  • Help on choosing which SQL Server 2008 scale-out solution to pick (replication, ...)

    - by usr
    I am currently crossing the jungle of SQL Server scale-out technologies like replication, log-shipping, mirroring... I have the following constraints on my choice: I want the read-only load to be spread accross the primary and the secondary (mirror, subscriber) server Write load can be sent directly to the primary server The solution should be nearly maintainance free. Schema changes should just replicate to the secondary server (attention: replication has some serious constraints here as it seems) Written data should be accessible very quickly (in under 1s, but better would be instantaneously) on the secondary server On server failure I can tollerate up to one hour of data loss easily. I am more concerned with easy scalability Here are some options for what I could pick: http://msdn.microsoft.com/en-us/library/bb510414.aspx. Any experience you could share?

  • bandwidth throttling C linux

    - by bob moch
    hi im currently creating a function to create a sleep time i can pause between packets for my port scanner im creating for personal/educational use for my home network. what im currently doing is opening /proc/net/dev and reading the 9th set of digits for the eth0 interface to find out the current packets being set and then reading it again and doing some math to figure out a delay to sleep between sending a packet to a port to identify it and fingerprint it. my problem is that no matter what throttle % i use it always seems to send the same rate of packets. i think its mainly my way of mathematically creating my sleep delay. edit:: dont mind the function declaration and the struct stuff all im doing is spawning this function in a thread and passing a pointer to a struct to the function, recreating the struct locally and then freeing the passed structs memory. void *bandwidthmonitor_cmd(void *param) { char cmdline[1024], *bytedata[19]; int i = 0, ii = 0; long long prevbytes = 0, currentbytes = 0, elapsedbytes = 0, byteusage = 0, maxthrottle = 0; command_struct bandwidth = *((command_struct *)param); free(param); //printf("speed: %d\n throttle: %d\n\n", UPLOAD_SPEED, bandwidth.throttle); maxthrottle = UPLOAD_SPEED * bandwidth.throttle / 100; //printf("max throttle:%lld\n", maxthrottle); FILE *f = fopen("/proc/net/dev", "r"); if(f != NULL) { while(1) { while(fgets(cmdline, sizeof(cmdline), f) != NULL) { cmdline[strlen(cmdline)] = '\0'; if(strncmp(cmdline, " eth0", 6) == 0) { bytedata[0] = strtok(cmdline, " "); while(bytedata[i] != NULL) { i++; bytedata[i] = strtok(NULL, " "); } bytedata[i + 1] = '\0'; currentbytes = atoi(bytedata[9]); } } i = 0; rewind(f); elapsedbytes = currentbytes - prevbytes; prevbytes = currentbytes; byteusage = 8 * (elapsedbytes / 1024); //printf("usage:%lld\n",byteusage); if(ii & 0x40) { SLEEP += (maxthrottle - byteusage) * -1.1;//-2.5; if(SLEEP < 0){ SLEEP = 0; } //printf("sleep:%d\n", SLEEP); } usleep(25000); ii++; } } return NULL; } SLEEP and UPLOAD_SPEED are global variables and UPLOAD_SPEED is in kb/s and generated via a speedtest function that gets the upload speed of my computer. this function is running inside a POSIX thread updating SLEEP which my threads doing the socket work grab to sleep by after every packet. as testing instead of only doing the ports i want to check i make it do all the ports over and over again so i can run dstat on a machine to check bandwidth and no matter what bandwidth.throttle is set to it always seems to generate the same amount of bandwidth to the dstat machine. the way i calculate how much i "should" throttle by is by finding the maximum throttle speed which is defined as maxthrottle = upload_speed * throttle / 100; for example if my upload speed was 1000kb/s and my throttle was 90 (90%) my max throttle would be 900kb/s from there it would find the current bytes sent from /proc/net/dev and then find my sleep time via incrementing or decrementing it via sleep += (maxthrottle - bytesysed) * -1.1; this should in theory increase or decrease the sleep time based on how many bytes used there are. the if(ii & 0x40) statement is just for some moderation control. it makes it so it only sets sleep to a new time every 30-40 iterations. final notes: the main problem is that the sleep timer does not seem to modify the speed of packets being set. or maybe its just my implementation because on a freshly restarted machine where /proc/net/dev has low numbers of bytes sent it seems to raise the sleep timer accordingly on my 60kb/s upload machine (ex if i set the throttle to 2 it will incline the sleep timer until network bandwidth out reaches the max bandwidth threshold, but when i try running it on a server which as been online forever it doesnt seem to work as nicely if at all. if anyone can suggest a new method of monitoring the network to adjust a sleep delay then let me know or if anyone sees a flaw in my code. thank you.

  • Replace non-html links with <A> tags

    - by tombazza
    I have a block of code that will take a block of text like the following: Sample text sample text http://www.google.com sample text Using the preg_replace_callback method and the following regular expression: preg_replace_callback('/http:\/\/([,\%\w.\-_\/\?\=\+\&\~\#\$]+)/', create_function( '$matches', '$url = $matches[1]; $anchorText = ( strlen($url) > 35 ? substr($url, 0, 35).\'...\' : $url); return \'<a href="http://\'. $url .\'">\'. $anchorText .\'</a>\';'), $str); Will convert the sample text to look like: Sample text sample text < a href="http://www.google.com"http://www.google.com< /a sample text My problem now is that we have introduced a rich text editor that can create links before being sent to the script. I need to update this piece of code so that it will ignore any URLs that are already inside an tag.

  • PivotControl item changing behavior in Silverlight Windows Phone 7

    - by Rosarch
    I have an app where the user is sent to a page with a PivotControl. The SelectedIndex is not known until the user navigates to the page. I'm setting the SelectedIndex, but it causes the PivotControl to start on index 0, then flip through to the index I set. This is kind of annoying, and I'd rather just have it go directly to the index I set. Is there some way around this? One hack I thought up was providing the data to pivotControl.ItemsSource in an order such that the item I want the user to start on is index 0 in ItemsSource. But that would be kind of messy, and I'm wondering if there's a more elegant solution.

  • How to send mail using PHP?

    - by phpaddict
    I'm using Windows Vista OS. PHP, MySQL as the database and Apache web server. I want to send notification to those who want to join in my site. But the problem is when I click submit. It doesn't send anything to the email address of the user. What to do you think is the best solution for this? <?php $to = "[email protected]"; $subject = "Hi!"; $body = "Hi,\n\nHow are you?"; if (mail($to, $subject, $body)) { echo("<p>Message successfully sent!</p>"); } else { echo("<p>Message delivery failed...</p>"); } ?>

  • JQuery-code on different content pages

    - by Ockonal
    Hello, I have a site with menu, which reloads content. Content is dynamically loadable, using ajax and php-script. At different content pages I need in different jquery-plugins. But If I'm writing including need plugin directly in some content page, I get a big lags during loading. So, now I'm includgin all plugins into main page... And it's not the best idea... Any suggestion? UPD: I have a div with content. Content is shown with effects (rolling up/down). When part of menu is clicked, I'm sending ajax-responce to the php script, which reads need text from database and returns it to the main page, from which I sent the responce. Than I'm pasting that content into a div and roll id down. So I'll include jquery-plugins in content pages, the animation of rolling will'nt be normal.

  • Zend Framework: How to handle exceptions in Ajax requests?

    - by understack
    Normally when an exception is thrown, Error controller takes command and displays error page with regular common header and footer. This behavior is not wanted in Ajax request. Because in case of error, whole html page is sent over. And in cases where I'm directly loading the content of http response in a div, this is even more unwanted. Instead in case of Ajax request, I just want to receive 'the actual error' thrown by exception. How can I do this? I think, one dirty way could be: set a var in ajax request and process accordingly. Not a good solution.

  • Suspension of Gmail account [closed]

    - by Ifeanyi Agu
    I have a Joomla site with my gmail account (google apps) being used as the SMTP server for sending mails. I also have a newsletter component on this site. I tried sending newsletter to all my subscribers and I noticed that the SMTP server could not be connected to. I then checked the emails of my company and noticed that the one I used to set it up was suspended. I cannot really explain why Google suspended the email account. Please could anyone tell me if Google saw the mails that were being sent as spam.

  • can I change my open ID URL change?

    - by dhruvbird
    I wanted to know if I can change my open ID url from say: www.abc.com/username to www.pqr.com/username while the relying party still thinks I am the same user? or even say: www.abc.com/something/username to www.abc.com/somethingelse/username I intuitively think that this is not possible since if it were, then it is possible for anyone to spoof anyone else's identity. Also, does Open ID specify which fields the relying party should use to ensure secure determination of the user's identity? For example, I would expect it to club the URL provided with the username/email address sent back by the Open ID server.

  • Send data over telnet without pressing enter

    - by Matt
    I've recently started messing around with Java sockets and telnet... I want the user to be able to connect to the server, just type a letter and have it sent to the server, without pressing enter to send it. I'm sure there's no way for the server to set this up, but maybe telnet has a parameter or something which could allow this? Maybe if I got the user to type stty cbreak or stty raw before running telnet, this would work? (UNIX only, I know!) If I can get telnet to do this then it saves me having to write a special client just for this feature...

  • How do you send an array as part of an (jquery) ajax request

    - by Ankur
    I tried to send an array as part of an ajax request like this: var query = []; // in between I add some values to 'query' $.ajax({ url: "MyServlet", data: query, dataType: "json", success: function(noOfResults) { alert(noOfResults); } }); } I wanted to see what I get back in the servlet, so I used this line: System.out.println(request.getParameterMap().toString()); Which returned {} suggesting an empty map. Firebug tells me I am getting a 400 bad request error If I send a queryString like attribute=value as the 'data' then everything works fine, so it has to do with not being able to send an array as is. What do I have to do to get that data into the servlet for further processing. I don't want to pull it out and turn it into a queryString in the JS if I can avoid it. EDIT: I used the .serializeArray() (jQuery) function before sending the data. I don't get the 400 but nothing useful is being sent through.

  • Email delivery failure - bounceback address

    - by user808532
    I've been looking for documentation on the standard behaviour for mail servers who fail to deliver their mail. I want the 'From' field to be different from the account that receives emails when there is a delivery failure. E.g. My program sends an email from '[email protected]', and on failure to deliver I want to be sent the delivery failure bounceback at '[email protected]'. Is this accomplished by setting the reply-to? Or should I login with the 'failedemails' account and therefore it will receive the email back? Thanks.

  • Socket.io Duplicate clients on a namespace

    - by Servernumber
    Hi I'm trying to use dynamic namespace to create them on demand. It's working except that I get duplicate or more client for some reason Server side : io.of("/" + group ).on("connection", function(socket_group) { socket_group.groupId = group; socket_group.on("infos", function(){ console.log("on the group !"); }) socket_group.on('list', function () { Urls.find({'group' : '...'}).sort({ '_id' : -1 }).limit(10).exec(function(err, data){ socket_group.emit('links', data); }); }) [...] }) Client Side : socket.emit('list', { ... }); On the client side only one command is sent but the server is always responding with 2 or more responses. Every time I close/open my app the response is incremented. Thanks if you find out.

  • How to have a run in an Service?

    - by user1497664
    I have implemented an service that runs in a seperate process. This service contains a separate thread where i have a socket connection. This thread has a run() where it is continuously sending data to the port. My problem is after triggering the run() in the thread i don't get any contact with it anymore, i can see in the program that have open the socket that it consciously sends the data but the idea was that i while it is running i could change data that it sends for an example time. here is my run in the external thread: public void run() { if(run) { // Team and player names message is sent when entering in a game setBaseMessage(); SendMessageToCOMPort(base_message + CalculateCRC(base_message)); sleep(); // waits for 100 ms } } Anyone have any idea what might be wrong ?

  • Are there any alternative to the header(); function ?

    - by Simon
    The thing is, I have a log-in page. And, when user enters Username & Password, they must be re-directed to success/failure page. Now, I have placed a "header('location:welcome.php');" after mysql rows are returned. But, it is giving me Header already sent errors, and I don't know much about PHP to do anything about it, let alone understand why it is happening. So, how to you transfer a user to another page after log-in data is verified? Same problem is happening with register, post, comment and search functions in my site.

  • Multifunctioning in Javascript

    - by Starx
    The concept is running multiple functions concurrently. The reason is, I have a page which performs various actions through ajax. These actions includes making multiple backups of new files uploaded in the upload directory. But I want this process to be initiated by a moderator. As this is a very lengthy process(might even take hours to complete), it blocks others ajax requests from executing, until this process complete. I want to execute functions along with the previously executed function parallelly. I am using jQuery's Ajax to sent initiate the request.

  • In Xcode, the main controller is hopelessly misconfigured. What are the steps I can take to fix all

    - by MikeN
    Somehow the main .xib file for my iphone project got deleted. I created a replacement .xib file, but the properties are not setup correctly for the MainWindow to load this one. I don't understand and am hopelessly confused about any of the properties and which ones may or may not be sent. What are the X properties that all need to be set to have this work correctly? I've checked all of these, but there appear to be others: 1) The app delegate for the project is set to the new ControllerUI class. 2) The MainWindow.xib shows the correct .xib file as being loaded from (it has a link in its UI to the .xib file that should be loaded on project run. There appear to be other settings that have to be changed and I can't find them. Is there a way in XCode to recreate the MainWindow.xib file? Should I just create a new project and move all of the other files into it?

  • WPF binding: Doing a temperature converter app

    - by Bob
    Hi there, I'm doing a little app that basically has 2 text boxes. You'll enter Fahrenheit into TextBoxA and Celsius into TextBoxB. As the text changes in TextBoxA I want the equivalent Celsius value to be displayed in TextBoxB and vice versa. I can come up with a solution pretty easy for this but i'm trying to be a little clever. Is there a way to do it all in Xaml except for a Convert class that does the maths? So basically I want the TextChanged event of one textBox to pass in it's value into a Converter class that is evaluated and sent to the other TextBox and visa versa. Anyone know how I can achieve this ... and if it's possible at all?

  • Function 'didFinishLaunchingWithOptions' getting invoked inappropriately

    - by clint
    I connected my IOS device to a MAC processor and installed/initialized my app running in xcode or dragged it from itunes folder. Now i physically disconnected my device from the processor and through wifi enabled in the device, sent notifications/messages through APNS to the device. I was able to successfully receive notifications in the device. Now after some time, i reconnected the device to the processor, which lead to a problem of the app launching again and calling 'didFinishLaunchingWithOptions' method again, which is not desirable as the launch/initialization should happen only once. This behaviour is random ie. every time when i disconnect/reconnect, it is not happening, only sometimes. Why is this happening. What could be the reason for this random behaviour. Any help will be appreciated.Thanks

  • Serialization of a TChan String

    - by J Fritsch
    I have declared the following type KEY = (IPv4, Integer) type TPSQ = TVar (PSQ.PSQ KEY POSIXTime) type TMap = TVar (Map.Map KEY [String]) data Qcfg = Qcfg { qthresh :: Int, tdelay :: Rational, cwpsq :: TPSQ, cwmap :: TMap, cw chan :: TChan String } deriving (Show) and would like this to be serializable in a sense that Qcfg can either be written to disk or be sent over the network. When I compile this I get the error No instances for (Show TMap, Show TPSQ, Show (TChan String)) arising from the 'deriving' clause of a data type declaration Possible fix: add instance declarations for (Show TMap, Show TPSQ, Show (TChan String)) or use a standalone 'deriving instance' declaration, so you can specify the instance context yourself When deriving the instance for (Show Qcfg) I am now not quite sure whether there is a chance at all to serialize my TChan although all individual nodes in it are members of the show class. For TMap and TPSQ I wonder whether there are ways to show the values in the TVar directly (because it does not get changed, so there should no need to lock it) without having to declare an instance that does a readTVar ?
