• my server suddenly crashes every 2 days or so. Programmer has no idea, please help find the cause, here is the top

  - by Alex

  Every couple of days my server suddenly crashes and I must request hardware reset at data center to get it back running. Today I came back to my shell and saw the server was dead and "top" was running on it, and see below for the "top" right before the crash. I opened /var/log/messages and scrolled to the reboot time and see nothing, no errors prior to the hard reboot. (I checked in /etc/syslog.conf and I see "*.info;mail.none;authpriv.none;cron.none /var/log/messages" , isn't this good enough to log all problems?) Usually when I look at the top, the swap is never used up like this! I also don't know why mysqld is at 323% cpu (server only runs drupal and its never slow or overloaded). Solver is my application. I don't know whats that 'sh' doing and 'dovecot' doing. Its driving me crazy over the last month, please help me solve this mystery and stop my downtimes. top - 01:10:06 up 6 days, 5 min, 3 users, load average: 34.87, 18.68, 9.03 Tasks: 500 total, 19 running, 481 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 96.6%sy, 0.0%ni, 1.7%id, 1.8%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 8165600k total, 8139764k used, 25836k free, 428k buffers Swap: 2104496k total, 2104496k used, 0k free, 8236k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4421 mysql 15 0 571m 105m 976 S 323.5 1.3 9:08.00 mysqld 564 root 20 -5 0 0 0 R 99.5 0.0 2:49.16 kswapd1 25767 apache 19 0 399m 8060 888 D 79.3 0.1 0:06.64 httpd 25781 apache 19 0 398m 5648 492 R 79.0 0.1 0:08.21 httpd 25961 apache 25 0 398m 5700 560 R 76.7 0.1 0:17.81 httpd 25980 apache 25 0 10816 668 520 R 75.0 0.0 0:46.95 sh 563 root 20 -5 0 0 0 D 71.4 0.0 3:12.37 kswapd0 25766 apache 25 0 399m 7256 756 R 69.7 0.1 0:39.83 httpd 25911 apache 25 0 398m 5612 480 R 58.8 0.1 0:17.63 httpd 25782 apache 25 0 440m 38m 648 R 55.2 0.5 0:18.94 httpd 25966 apache 25 0 398m 5640 556 R 55.2 0.1 0:48.84 httpd 4588 root 25 0 74860 596 476 R 53.9 0.0 0:37.90 crond 25939 apache 25 0 2776 172 84 R 48.9 0.0 0:59.46 solver 4575 root 25 0 397m 6004 1144 R 48.6 0.1 1:00.43 httpd 25962 apache 25 0 398m 5628 492 R 47.9 0.1 0:14.58 httpd 25824 apache 25 0 440m 39m 680 D 47.3 0.5 0:57.85 httpd 25968 apache 25 0 398m 5612 528 R 46.6 0.1 0:42.73 httpd 4477 root 25 0 6084 396 280 R 46.3 0.0 0:59.53 dovecot 25982 root 25 0 397m 5108 240 R 45.9 0.1 0:18.01 httpd 25943 apache 25 0 2916 172 8 R 44.0 0.0 0:53.54 solver 30687 apache 25 0 468m 63m 1124 D 42.3 0.8 0:45.02 httpd 25978 apache 25 0 398m 5688 600 R 23.8 0.1 0:40.99 httpd 25983 root 25 0 397m 5272 384 D 14.9 0.1 0:18.99 httpd 935 root 10 -5 0 0 0 D 14.2 0.0 1:54.60 kjournald 25986 root 25 0 397m 5308 420 D 8.9 0.1 0:04.75 httpd 4011 haldaemo 25 0 31568 1476 716 S 5.6 0.0 0:24.36 hald 25956 apache 23 0 398m 5872 644 S 5.6 0.1 0:13.85 httpd 18336 root 18 0 13004 1332 724 R 0.3 0.0 1:46.66 top 1 root 18 0 10372 212 180 S 0.0 0.0 0:05.99 init 2 root RT -5 0 0 0 S 0.0 0.0 0:00.95 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 0:00.01 ksoftirqd/0 4 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT -5 0 0 0 S 0.0 0.0 0:00.15 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:00 .06 ksoftirqd/1 here is a normal top, when server is working fine: top - 01:50:41 up 21 min, 1 user, load average: 2.98, 2.70, 1.68 Tasks: 271 total, 2 running, 269 sleeping, 0 stopped, 0 zombie Cpu(s): 15.0%us, 1.1%sy, 0.0%ni, 81.4%id, 2.4%wa, 0.1%hi, 0.0%si, 0.0%st Mem: 8165600k total, 2035856k used, 6129744k free, 60840k buffers Swap: 2104496k total, 0k used, 2104496k free, 283744k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2204 apache 17 0 466m 83m 19m S 25.9 1.0 0:22.16 httpd 11347 apache 15 0 466m 83m 19m S 25.9 1.0 0:26.10 httpd 18204 apache 18 0 481m 97m 19m D 25.2 1.2 0:13.99 httpd 4644 apache 18 0 481m 100m 19m D 24.6 1.3 1:17.12 httpd 4727 apache 17 0 481m 99m 19m S 24.3 1.2 1:10.77 httpd 4777 apache 17 0 482m 102m 21m S 23.6 1.3 1:38.27 httpd 8924 apache 15 0 483m 99m 19m S 22.3 1.3 1:13.41 httpd 9390 apache 18 0 483m 99m 19m S 18.9 1.2 1:05.35 httpd 4728 apache 16 0 481m 101m 19m S 14.3 1.3 1:12.50 httpd 4648 apache 15 0 481m 107m 27m S 12.6 1.4 1:18.62 httpd 24955 apache 15 0 467m 82m 19m S 3.3 1.0 0:21.80 httpd 4722 apache 15 0 503m 118m 19m R 1.7 1.5 1:17.79 httpd 4647 apache 15 0 484m 105m 20m S 1.3 1.3 1:40.73 httpd 4643 apache 16 0 481m 100m 20m S 0.7 1.3 1:11.80 httpd 1561 root 15 0 12900 1264 828 R 0.3 0.0 0:00.54 top 4434 mysql 15 0 496m 55m 4812 S 0.3 0.7 0:06.69 mysqld 4646 apache 15 0 481m 100m 19m S 0.3 1.3 1:25.51 httpd 1 root 18 0 10372 692 580 S 0.0 0.0 0:02.09 init 2 root RT -5 0 0 0 S 0.0 0.0 0:00.03 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/0 4 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/1 7 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/1 8 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/2 9 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/2 10 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/2 11 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/3 12 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/3 13 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/3 14 root RT -5 0 0 0 S 0.0 0.0 0:00.03 migration/4 15 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/4 16 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/4 17 root RT -5 0 0 0 S 0.0 0.0 0:00.02 migration/5 18 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/5 19 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/5 20 root RT -5 0 0 0 S 0.0 0.0 0:00.01 migration/6 21 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/6 22 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/6 23 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/7

• Invalid workspace Error while installing new EAR on IBM WAS Server

  Hi, When I try to install a new EAR on IBM WAS 6.1 server through "Install new Application" option, it throws an error after 20-30 mins on the installation screen "ADMA5006E: An error occurred configuring ABC in WebSphere Application Server repository: com.ibm.ws.sm.workspace.WorkSpaceException: WKSP0009E Workspace is invalid " and the logs too show [6/11/09 13:07:55:222 IST] 0000002b SystemErr R com.ibm.ws.sm.workspace.WorkSpaceException: WKSP0009E Workspace is invalid [6/11/09 13:07:55:269 IST] 0000002b SystemErr R at com.ibm.ws.sm.workspace.impl.WorkSpaceLogger.createException(WorkSpaceLogger.java:85) [6/11/09 13:07:55:269 IST] 0000002b SystemErr R at com.ibm.ws.sm.workspace.impl.WorkSpaceLogger.createException(WorkSpaceLogger.java:57) Please let me know if anyone has an idea about this one.

• Windows "known folders": is there any one of them which is reliably read/write for all users on all

  - by Stabledog

  SHGetKnownFolderPath() and its cohorts accept one of the constants defined here (http://msdn.microsoft.com/en-us/library/dd378457%28v=VS.85%29.aspx ), returning the path to a directory. I'm looking for one of these folders which is reliably writable by all users (including LocalSystem) on XP, Vista, and Windows 7... but I think I'm striking out. It appears that, in fact, there is no single location on the hard drive anymore where you can put a file and be assured that all users can write to it on all these OS versions, without fiddling the permissions first. Is this true?

• Event Handlers Not Getting Called? - wxWidgets

  - by Alex

  Hello all, I'm working on a program for my C++ programming class, using wxWidgets. I'm having a huge problem in that my event handlers (I assume) are not getting called, because when I click on the button to trigger the event, nothing happens. My question is: Can you help me find the problem and explain why they would not be getting called? The event handlers OnAbout and OnQuit are working, just not OnCompute or OnClear. I'm really frustrated as I can't figure this out. Thanks a bunch in advance! #include "wx/wx.h" #include "time.h" #include <string> using std::string; // create object of Time class Time first; class App: public wxApp { virtual bool OnInit(); }; class MainPanel : public wxPanel { public: // Constructor for panel class // Constructs my panel class // Params - wxWindow pointer // no return type // pre-conditions: none // post-conditions: none MainPanel(wxWindow* parent); // OnCompute is the event handler for the Compute button // params - none // preconditions - none // postconditions - tasks will have been carried otu successfully // returns void void OnCompute(wxCommandEvent& WXUNUSED(event)); // OnClear is the event handler for the Clear button // params - none // preconditions - none // postconditions - all text areas will be cleared of data // returns void void OnClear(wxCommandEvent& WXUNUSED(event)); // Destructor for panel class // params none // preconditions - none // postconditions - none // no return type ~MainPanel( ); private: wxStaticText *startLabel; wxStaticText *endLabel; wxStaticText *pCLabel; wxStaticText *newEndLabel; wxTextCtrl *start; wxTextCtrl *end; wxTextCtrl *pC; wxTextCtrl *newEnd; wxButton *compute; wxButton *clear; DECLARE_EVENT_TABLE() }; class MainFrame: public wxFrame { private: wxPanel *mainPanel; public: MainFrame(const wxString& title, const wxPoint& pos, const wxSize& size); void OnQuit(wxCommandEvent& event); void OnAbout(wxCommandEvent& event); ~MainFrame(); DECLARE_EVENT_TABLE() }; enum { ID_Quit = 1, ID_About, BUTTON_COMPUTE = 100, BUTTON_CLEAR = 200 }; IMPLEMENT_APP(App) BEGIN_EVENT_TABLE(MainFrame, wxFrame) EVT_MENU(ID_Quit, MainFrame::OnQuit) EVT_MENU(ID_About, MainFrame::OnAbout) END_EVENT_TABLE() BEGIN_EVENT_TABLE(MainPanel, wxPanel) EVT_MENU(BUTTON_COMPUTE, MainPanel::OnCompute) EVT_MENU(BUTTON_CLEAR, MainPanel::OnClear) END_EVENT_TABLE() bool App::OnInit() { MainFrame *frame = new MainFrame( _("Good Guys Delivery Time Calculator"), wxPoint(50, 50), wxSize(450,340) ); frame->Show(true); SetTopWindow(frame); return true; } MainPanel::MainPanel(wxWindow* parent) : wxPanel(parent) { startLabel = new wxStaticText(this, -1, "Start Time:", wxPoint(75, 35)); start = new wxTextCtrl(this, -1, "", wxPoint(135, 35), wxSize(40, 21)); endLabel = new wxStaticText(this, -1, "End Time:", wxPoint(200, 35)); end = new wxTextCtrl(this, -1, "", wxPoint(260, 35), wxSize(40, 21)); pCLabel = new wxStaticText(this, -1, "Percent Change:", wxPoint(170, 85)); pC = new wxTextCtrl(this, -1, "", wxPoint(260, 85), wxSize(40, 21)); newEndLabel = new wxStaticText(this, -1, "New End Time:", wxPoint(180, 130)); newEnd = new wxTextCtrl(this, -1, "", wxPoint(260, 130), wxSize(40, 21)); compute = new wxButton(this, BUTTON_COMPUTE, "Compute", wxPoint(135, 185), wxSize(75, 35)); clear = new wxButton(this, BUTTON_CLEAR, "Clear", wxPoint(230, 185), wxSize(75, 35)); } MainPanel::~MainPanel() {} MainFrame::MainFrame(const wxString& title, const wxPoint& pos, const wxSize& size) : wxFrame( NULL, -1, title, pos, size ) { mainPanel = new MainPanel(this); wxMenu *menuFile = new wxMenu; menuFile->Append( ID_About, _("&About...") ); menuFile->AppendSeparator(); menuFile->Append( ID_Quit, _("E&xit") ); wxMenuBar *menuBar = new wxMenuBar; menuBar->Append( menuFile, _("&File") ); SetMenuBar( menuBar ); CreateStatusBar(); SetStatusText( _("Hi") ); } MainFrame::~MainFrame() {} void MainFrame::OnQuit(wxCommandEvent& WXUNUSED(event)) { Close(TRUE); } void MainFrame::OnAbout(wxCommandEvent& WXUNUSED(event)) { wxMessageBox( _("Alex Olson\nProject 11"), _("About"), wxOK | wxICON_INFORMATION, this); } void MainPanel::OnCompute(wxCommandEvent& WXUNUSED(event)) { int startT; int endT; int newEndT; double tD; wxString startTString = start->GetValue(); wxString endTString = end->GetValue(); startT = wxAtoi(startTString); endT = wxAtoi(endTString); pC->GetValue().ToDouble(&tD); first.SetStartTime(startT); first.SetEndTime(endT); first.SetTimeDiff(tD); try { first.ValidateData(); newEndT = first.ComputeEndTime(); *newEnd << newEndT; } catch (BaseException& e) { wxMessageBox(_(e.GetMessage()), _("Something Went Wrong!"), wxOK | wxICON_INFORMATION, this); } } void MainPanel::OnClear(wxCommandEvent& WXUNUSED(event)) { start->Clear(); end->Clear(); pC->Clear(); newEnd->Clear(); }

• Removed MAMP from OS X, dyld still using MAMP libraries

  - by dizzee

  When I try and use a populator or sphinx on a Ruby app I keep receiving dyld errors. I used to use MAMP on OS X Leopard but since I've upgraded to Snow Leopard and am now using standalone MySQL (10.5 64-bit). $ rake ts:index Would return dyld: Library not loaded: /Applications/MAMP/Library/lib/mysql/libmysqlclient.15.dylib Referenced from: /usr/local/bin/indexer Reason: image not found rake aborted! Even though to remove MAMP I just deleted the /Applications/MAMP directory. But it still looks like dylib has references to it. I've tried running: $ sudo update_dyld_shared_cache -verify and restarting but the problem still persists. OS X 10.6.1, MySQL 5.0.85 (x86_64)

• Uploadify Minimum Image Width And Height

  - by Richard Knop

  So I am using the Uplodify plugin to allow users to upload multiple images at once. The problem is I need to set a minimum width and height for images. Let's say 150x150px is the smallest image users can upload. How can I set this limitation in the Uploadify plugin? When user tries to upload smaller picture, I would like to display some error message as well. Here is the PHP file that is called bu the plugin to upload images: <?php define('BASE_PATH', substr(dirname(dirname(__FILE__)), 0, -22)); // set the include path set_include_path(BASE_PATH . '/../library' . PATH_SEPARATOR . BASE_PATH . '/library' . PATH_SEPARATOR . get_include_path()); // autoload classes from the library function __autoload($class) { include str_replace('_', '/', $class) . '.php'; } $configuration = new Zend_Config_Ini(BASE_PATH . '/application' . '/configs/application.ini', 'development'); $dbAdapter = Zend_Db::factory($configuration->database); Zend_Db_Table_Abstract::setDefaultAdapter($dbAdapter); function _getTable($table) { include BASE_PATH . '/application/modules/default/models/' . $table . '.php'; return new $table(); } $albums = _getTable('Albums'); $media = _getTable('Media'); if (false === empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $extension = end(explode('.', $_FILES['Filedata']['name'])); // insert temporary row into the database $data = array(); $data['type'] = 'photo'; $data['type2'] = 'public'; $data['status'] = 'temporary'; $data['user_id'] = $_REQUEST['user_id']; $paths = $media->add($data, $extension, $dbAdapter); // save the photo move_uploaded_file($tempFile, BASE_PATH . '/public/' . $paths[0]); // create a thumbnail include BASE_PATH . '/library/My/PHPThumbnailer/ThumbLib.inc.php'; $thumb = PhpThumbFactory::create(BASE_PATH . '/public/' . $paths[0]); $thumb->adaptiveResize(85, 85); $thumb->save(BASE_PATH . '/public/' . $paths[1]); // add watermark to the bottom right corner $pathToFullImage = BASE_PATH . '/public/' . $paths[0]; $size = getimagesize($pathToFullImage); switch ($extension) { case 'gif': $im = imagecreatefromgif($pathToFullImage); break; case 'jpg': $im = imagecreatefromjpeg($pathToFullImage); break; case 'png': $im = imagecreatefrompng($pathToFullImage); break; } if (false !== $im) { $white = imagecolorallocate($im, 255, 255, 255); $font = BASE_PATH . '/public/fonts/arial.ttf'; imagefttext($im, 13, // font size 0, // angle $size[0] - 132, // x axis (top left is [0, 0]) $size[1] - 13, // y axis $white, $font, 'HunnyHive.com'); switch ($extension) { case 'gif': imagegif($im, $pathToFullImage); break; case 'jpg': imagejpeg($im, $pathToFullImage, 100); break; case 'png': imagepng($im, $pathToFullImage, 0); break; } imagedestroy($im); } echo "1"; } And here's the javascript: $(document).ready(function() { $('#photo').uploadify({ 'uploader' : '/flash-uploader/scripts/uploadify.swf', 'script' : '/flash-uploader/scripts/upload-public-photo.php', 'cancelImg' : '/flash-uploader/cancel.png', 'scriptData' : {'user_id' : 'USER_ID'}, 'queueID' : 'fileQueue', 'auto' : true, 'multi' : true, 'sizeLimit' : 2097152, 'fileExt' : '*.jpg;*.jpeg;*.gif;*.png', 'wmode' : 'transparent', 'onComplete' : function() { $.get('/my-account/temporary-public-photos', function(data) { $('#temporaryPhotos').html(data); }); } }); $('#upload_public_photo').hover(function() { var titles = '{'; $('.title').each(function() { var title = $(this).val(); if ('Title...' != title) { var id = $(this).attr('name'); id = id.substr(5); title = jQuery.trim(title); if (titles.length > 1) { titles += ','; } titles += '"' + id + '"' + ':"' + title + '"'; } }); titles += '}'; $('#titles').val(titles); }); }); Now bear in mind that I know how to check images dimensions in the PHP file. But I'm not sure how to modify the javascript so it won't upload images with very small dimensions.

• iPhone long plist

  - by Zac Altman

  I have some data i want to add in to my app...about 650 categories (includes a name + id number), each with an average of 85 items (each with a name/id number). Will the iPhone support such a large plist? I want to first display the categories in a UITableView, when a category is selected I want to display all of the associated items. Having such a large plist, im not sure if the iPhone will lag when loading the items. At over 51,000 lines it seems like...it might.

I'm having a huge problem in that my event handlers (I assume) are not getting called, because when I click on the button to trigger the event, nothing happens. My question is: Can you help me find the problem and explain why they would not be getting called? The event handlers OnAbout and OnQuit are working, just not OnCompute or OnClear. I'm really frustrated as I can't figure this out. Thanks a bunch in advance! #include "wx/wx.h" #include "time.h" #include <string> using std::string; // create object of Time class Time first; class App: public wxApp { virtual bool OnInit(); }; class MainPanel : public wxPanel { public: // Constructor for panel class // Constructs my panel class // Params - wxWindow pointer // no return type // pre-conditions: none // post-conditions: none MainPanel(wxWindow* parent); // OnCompute is the event handler for the Compute button // params - none // preconditions - none // postconditions - tasks will have been carried otu successfully // returns void void OnCompute(wxCommandEvent& WXUNUSED(event)); // OnClear is the event handler for the Clear button // params - none // preconditions - none // postconditions - all text areas will be cleared of data // returns void void OnClear(wxCommandEvent& WXUNUSED(event)); // Destructor for panel class // params none // preconditions - none // postconditions - none // no return type ~MainPanel( ); private: wxStaticText *startLabel; wxStaticText *endLabel; wxStaticText *pCLabel; wxStaticText *newEndLabel; wxTextCtrl *start; wxTextCtrl *end; wxTextCtrl *pC; wxTextCtrl *newEnd; wxButton *compute; wxButton *clear; DECLARE_EVENT_TABLE() }; class MainFrame: public wxFrame { private: wxPanel *mainPanel; public: MainFrame(const wxString& title, const wxPoint& pos, const wxSize& size); void OnQuit(wxCommandEvent& event); void OnAbout(wxCommandEvent& event); ~MainFrame(); DECLARE_EVENT_TABLE() }; enum { ID_Quit = 1, ID_About, BUTTON_COMPUTE = 100, BUTTON_CLEAR = 200 }; IMPLEMENT_APP(App) BEGIN_EVENT_TABLE(MainFrame, wxFrame) EVT_MENU(ID_Quit, MainFrame::OnQuit) EVT_MENU(ID_About, MainFrame::OnAbout) END_EVENT_TABLE() BEGIN_EVENT_TABLE(MainPanel, wxPanel) EVT_MENU(BUTTON_COMPUTE, MainPanel::OnCompute) EVT_MENU(BUTTON_CLEAR, MainPanel::OnClear) END_EVENT_TABLE() bool App::OnInit() { MainFrame *frame = new MainFrame( _("Good Guys Delivery Time Calculator"), wxPoint(50, 50), wxSize(450,340) ); frame->Show(true); SetTopWindow(frame); return true; } MainPanel::MainPanel(wxWindow* parent) : wxPanel(parent) { startLabel = new wxStaticText(this, -1, "Start Time:", wxPoint(75, 35)); start = new wxTextCtrl(this, -1, "", wxPoint(135, 35), wxSize(40, 21)); endLabel = new wxStaticText(this, -1, "End Time:", wxPoint(200, 35)); end = new wxTextCtrl(this, -1, "", wxPoint(260, 35), wxSize(40, 21)); pCLabel = new wxStaticText(this, -1, "Percent Change:", wxPoint(170, 85)); pC = new wxTextCtrl(this, -1, "", wxPoint(260, 85), wxSize(40, 21)); newEndLabel = new wxStaticText(this, -1, "New End Time:", wxPoint(180, 130)); newEnd = new wxTextCtrl(this, -1, "", wxPoint(260, 130), wxSize(40, 21)); compute = new wxButton(this, BUTTON_COMPUTE, "Compute", wxPoint(135, 185), wxSize(75, 35)); clear = new wxButton(this, BUTTON_CLEAR, "Clear", wxPoint(230, 185), wxSize(75, 35)); } MainPanel::~MainPanel() {} MainFrame::MainFrame(const wxString& title, const wxPoint& pos, const wxSize& size) : wxFrame( NULL, -1, title, pos, size ) { mainPanel = new MainPanel(this); wxMenu *menuFile = new wxMenu; menuFile->Append( ID_About, _("&About...") ); menuFile->AppendSeparator(); menuFile->Append( ID_Quit, _("E&xit") ); wxMenuBar *menuBar = new wxMenuBar; menuBar->Append( menuFile, _("&File") ); SetMenuBar( menuBar ); CreateStatusBar(); SetStatusText( _("Hi") ); } MainFrame::~MainFrame() {} void MainFrame::OnQuit(wxCommandEvent& WXUNUSED(event)) { Close(TRUE); } void MainFrame::OnAbout(wxCommandEvent& WXUNUSED(event)) { wxMessageBox( _("Alex Olson\nProject 11"), _("About"), wxOK | wxICON_INFORMATION, this); } void MainPanel::OnCompute(wxCommandEvent& WXUNUSED(event)) { int startT; int endT; int newEndT; double tD; wxString startTString = start->GetValue(); wxString endTString = end->GetValue(); startT = wxAtoi(startTString); endT = wxAtoi(endTString); pC->GetValue().ToDouble(&tD); first.SetStartTime(startT); first.SetEndTime(endT); first.SetTimeDiff(tD); try { first.ValidateData(); newEndT = first.ComputeEndTime(); *newEnd << newEndT; } catch (BaseException& e) { wxMessageBox(_(e.GetMessage()), _("Something Went Wrong!"), wxOK | wxICON_INFORMATION, this); } } void MainPanel::OnClear(wxCommandEvent& WXUNUSED(event)) { start->Clear(); end->Clear(); pC->Clear(); newEnd->Clear(); }

• How to implement SCORM in Objective C

  - by iranjan

  Hey, Do you know how to implement SCORM (Sharable Content Object Reference Model) in Objective C for eLearning content? Let me explain you what exactly I am looking for. I have one MCQ (multiple choice question) application which has 4 questions. On attempting each question I want my application to interact with a SCORM compatible server with result (whether the user has attempted correct one or not). The communication channel should be to and fro. May be at the end of the MCQ I want to show result which will come from the server with some calculations*(like Score : 85% number of attempts : 16 average score:16.7% etc.)*. How should I go about it? Please guide if you have already achieved it regards Ranjan.

• Implementing a horizontal compass on the iPhone - algorithm?

  - by Andrew Johnson

  A horizontal compass looks something like this if you are facing due East (90 degrees). 85----90---95 If you were facing due 355 degrees northwest, it would look like this: 350----355---0 As you turn the compass, the number should cycle from 0 - 360 - 0 So, my question is, how would you implement a view like this on the iPhone? I had a couple of ideas: Make one long image with all numbers and tick marks, and shift it left/right when the compass heading changes Create pieces of the view as tiles and append them when the compass heading changes. Create a line of tick marks that shifts with the compass heading, and just write numbers on it as needed. How would you attack this problem? Im mainly looking for algorithmic advice, but if you ave code or pseudo-code to demonstrate, that would be helpful too.

• imagejpeg memory exhaustion

  - by 0plus1

  I'm creating thumbnails cycling through a lot of images, when I find a large image I get: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 13056 bytes) Now I already know how to circumvent this with: ini_set('memory_limit', '-1'); What I want to know is why it exhaust the memory! Is there some debug tools that will show me exactly when memory is exhausting? And specifically that will show me if there are variables/arrays that are killing my memory? OR, are there better way to resize images other then: $thumb=imagecreatetruecolor($newwidth,$newheight); $source=imagecreatefromjpeg($imgfile); imagecopyresampled($thumb,$source,0,0,0,0,$newwidth,$newheight,$width,$height); imagejpeg($thumb,$destinationfile,85); ? Thank you very much!

• Media Foundation: another way to call IMFActivate::ShutdownObject?

  - by KenC

  Hi, Here is a question about IMFActivate::ActivateObject and IMFActivate::ShutdownObject in Media Foundation. According to MSDN, the component that calls ActivateObject is responsible for calling ShutdownObject. But there are two examples not following this rule: http://msdn.microsoft.com/en-us/library/dd388503%28VS.85%29.aspx and http://msdn.microsoft.com/en-us/library/dd317912%28VS.85%29.aspx In these two examples, they call ActivateObject and then release IMFActivate interface without calling ShutdownObject method. This is going to lead to memory leaking, right? Or there is another way to release the resource occupied by the object? (Can I use IMFMediaSource::Shutdown to release the object instead of using IMFActivate::ShutdownObject) Thanks in advance.

• How to Look Up Email by Full Name in Active Directory?

  - by Danny

  I want to search for a user's email by using Active Directory. Available is the user's full name (ex. "John Doe" for the email with an email "[email protected]"). From what I've searched, this comes close to what I'm looking to do -- except that the Filter is set to "SAMAccountName", which is not what I have. Unless I'm misunderstanding, I just need to pick the right attribute and toss in the full name name in the same way. Unfortunately, I don't know what this attribute is, apparently no one has had to ask about searching for information in this manner, and that is a pretty big list (msdn * microsoft * com/en-us/library/ms675090(v=VS.85) * aspx, stackoverflow didn't let me link 2 hyperlinks because I don't have 10 rep) of attributes. Does anyone know how to obtain the user's email address through an Active Directory lookup by using the user's full name?

So I can easily pick fields by a simple query. if I can use Bacthmove Plz give me the guild lines. Also Is there any other Techniques for this? Thanks and Regards, Vijesh V.Nair

• How can I parse a C header file with Perl?

  - by Alphaneo

  Hi, I have a header file in which there is a large struct. I need to read this structure using some program and make some operations on each member of the structure and write them back. For example I have some structure like const BYTE Some_Idx[] = { 4,7,10,15,17,19,24,29, 31,32,35,45,49,51,52,54, 55,58,60,64,65,66,67,69, 70,72,76,77,81,82,83,85, 88,93,94,95,97,99,102,103, 105,106,113,115,122,124,125,126, 129,131,137,139,140,149,151,152, 153,155,158,159,160,163,165,169, 174,175,181,182,183,189,190,193, 197,201,204,206,208,210,211,212, 213,214,215,217,218,219,220,223, 225,228,230,234,236,237,240,241, 242,247,249}; Now, I need to read this and apply some operation on each of the member variable and create a new structure with different order, something like: const BYTE Some_Idx_Mod_mul_2[] = { 8,14,20, ... ... 484,494,498}; Is there any Perl library already available for this? If not Perl, something else like Python is also OK. Can somebody please help!!!

• GROUP BY as a way to pick the first row from a group of similar rows, is this correct, is there any

  - by FipS

  I have a table which stores test results like this: user | score | time -----+-------+------ aaa | 90% | 10:30 bbb | 50% | 9:15 *** aaa | 85% | 10:15 aaa | 90% | 11:00 *** ... What I need is to get the top 10 users: user | score | time -----+-------+------ aaa | 90% | 11:00 bbb | 50% | 9:15 ... I've come up with the following SELECT: SELECT * FROM (SELECT user, score, time FROM tests_score ORDER BY user, score DESC, time DESC) t1 GROUP BY user ORDER BY score DESC, time LIMIT 10 It works fine but I'm not quite sure if my use of ORDER BY is the right way to pick the first row of each group of sorted records. Is there any better practice to achieve the same result? (I use MySQL 5)

• ANSI SQL question - how to insert or update a record if it already exists?

  - by morpheous

  Although I am using mySQL (for now), I dont want any DB specific SQL. I am trying to insert a record if it doesn't exist, and update a field if it does exist. I want to use ANSI SQL. The table looks something like this: create table test_table (id int, name varchar(16), weight double) ; //test data insert into test_table (id, name, weight) values(1,'homer', 900); insert into test_table (id, name, weight) values(2,'marge', 85); insert into test_table (id, name, weight) values(3,'bart', 25); insert into test_table (id, name, weight) values(4,'lisa', 15); If the record exists, I want to update the weight (increase by say 10)
