  • graph algorithms on GPU

    - by scatman
    the current GPU threads are somehow limited (memory limit, limit of data structures, no recursion...). do you think it would be feasible to implement a graph theory problem on GPU. for example vertex cover? dominating set? independent set? max clique?.... is it also feasible to have branch-and-bound algorithms on GPUs? Recursive backtracking?

  • Mongrel not using latest deployed code, despite multiple restarts

    - by ming yeow

Where could the server be potentially caching the model files?

  • How do I constrain the SCons Command builder to run only if its dependencies have changed?

    - by saffsd
    I am using the Command builder in scons to specify that a particular script needs to be invoked to produce a particular file. I would like to only run the script if it has been modified since the file was previously generated. The default behaviour of the Command builder seems to be to always run the script. How can I change this? This is my current SConstruct: speed = Command('speed_analysis.tex','','python code/speed.py') report = PDF(target = 'report.pdf', source = 'report.tex') Depends(report, speed)

  • "session" bean scope in a web application - reliable ?

    - by EugeneP
    Can you rely on this scope and be sure that every time 1) a new session starts, the Spring bean will be initialized with default values 2) while session is kept alive, the current object will store its state during session life, will never be lost or corrupted and can always be got with [webappcontext].getBean ?

  • Sending HTML email from PHP

    - by KevinM
    I am trying to send a simple HTML e-mail from PHP. The code below simply results in a blank e-mail in GMail. It also has an empty attachment called 'noname', which is not at all what I want; though that might just be a symptom of it not working. The code I am using is: <?php //define the receiver of the email $to = '[email protected]'; //define the subject of the email $subject = 'Test HTML email'; //create a boundary string. It must be unique //so we use the MD5 algorithm to generate a random hash $random_hash = md5(date('r', time())); //define the headers we want passed. Note that they are separated with \r\n $headers = "From: [email protected]\r\nReply-To: [email protected]"; //add boundary string and mime type specification $headers .= "\r\nContent-Type: multipart/alternative; boundary=\"PHP-alt-".$random_hash."\""; //define the body of the message. ob_start(); //Turn on output buffering ?> --PHP-alt-<?php echo $random_hash; ?> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Hello World!!! This is simple text email message. --PHP-alt-<?php echo $random_hash; ?> MIME-Version: 1.0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 7bit <h2>Hello World!</h2> <p>This is something with <b>HTML</b>formatting.</p> --PHP-alt-<?php echo $random_hash; ?>-- <? //copy current buffer contents into $message variable and delete current output buffer $message = ob_get_clean(); //send the email $mail_sent = @mail( $to, $subject, $message, $headers ); //if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" echo $mail_sent ? "Mail sent" : "Mail failed";

  • Auto-Completion in Unix VI editor

    - by IllustratedInsomnia
    Hey guys, after using graphical IDE's like Visual Studio, I'm used to pressing CTRL+Space to auto-complete a variable or function name. Now, I know such a thing isn't completely possible in VI, but I heard there was a list of commands that could be mapped that allowed automatic completion of variables and functions in the current file opened. Does anyone know what this sequence is? Thanks in advance.

  • cpp/Qt : per class debugging

    - by dzen
    I'm developing a Qt application. For each class, I'm trying to mimic the framework, such as error() and errorString() method, use of Private implementation. But I would like to add a per class debugging: Set a macro to the desired level of debug, have a macro or a function that knows the level of debug, and use qDebug() or qWarning() which is class independant, and will know the current class's name (for some pretty prints) Anyone have a good idea to implement this ?

  • Does control return after "execvp()"

    - by Ajay Garg
    "execvp()" replaces the current program with the to-be-execed program (of course in the same process context). So, putting, say, any printf() calls after execvp() won't work. That is what the docs say, and I have verified it as well. But then, why is _exit() needed..? Does it so happen that the control DOES return to statements post execvp() ? I will be grateful for any pointers. Thanks

  • Determine modifier key state without an InputEvent object in Java

    - by heycam
    I need to determine the current state of the Shift key, but at the time I need the state I don't have an InputEvent object around. I need something like java.awt.Toolkit.getLockingKeyState(int) that works for Shift, not just the locking keys like VK_CAPS_LOCK. Is there a way I can do this without listening to input events and storing the for later when I need to check the state? Thanks!

  • Is it possible to have yui editor change paragraph style without selecting text?

    - by user126861
    Is it possible to change the behavior of the yui text editor so that when you make markup changes (via the toolbar bar buttons), for example changing from a paragraph to say a heading or to a list, and you dont have any text selected it assumes you mean the current block that the cursor is in So to change a paragraph to a heading rather than selecting the whole line you just place the cursor somewhere in the paragraph and select heading from the styles drop down.

  • Helping Kohana 3 ORM to speed up a little

    - by Luke
    I noticed that Kohana 3 ORM runs a "SHOW FULL COLUMNS" for each of my models when I start using them: SHOW FULL COLUMNS FROM `mytable` This query might take a few clock cycles to execute (in the Kohana profiler it's actually the slowest of all queries ran in my current app). Is there a way to help Kohana 3 ORM to speed up by disabling this behaviour and explicitly define the columns in my models instead?
