  • Should I refactor this code?

    - by user156814
    The code is for a view debate page. The code is supposed to determine whether or not to show an add reply form to the viewing user. If the user is logged in, and the user is not the creator of the debate, then check if the user already replied to the debate. If the user did not already reply to the debate then show the form... Otherwise, Check If the user wants to edit their already existing reply by looking in the url for the reply id If any of these tests dont pass, Then I save the reason as an int and pass that to a switch statement in the view. The logic seems easy enough, but my code seems a little sloppy. Here's the code.. (using Kohana V2.3.4) public function view($id = 0) { $debate = ORM::factory('debate')->with('user')->with('category')->find($id); if ($debate->loaded == FALSE) { url::redirect(); } // series of tests to show an add reply form if ($this->logged_in) { // is the viewer the creator? if ($this->user->id != $debate->user->id) { // has the user already replied? if (ORM::factory('reply') ->where(array('debate_id' => $id, 'user_id' => $this->user->id)) ->count_all() == 0) { $form = $errors = array ( 'body' => '', 'choice_id' => '', 'add' => '' ); if ($post = $this->input->post()) { $reply = ORM::factory('reply'); // validate and insert the reply if ($reply->add($post, TRUE)) { url::redirect(url::current()); } $form = arr::overwrite($form, $post->as_array()); $errors = arr::overwrite($errors, $post->errors('reply_errors')); } } // editing a reply? else if (($rid = (int) $this->input->get('edit')) AND ($reply = ORM::factory('reply') ->where(array('debate_id' => $id, 'user_id' => $this->user->id)) ->find($rid))) { $form = $errors = array ( 'body' => '', 'choice_id' => '', 'add' => '' ); // autocomplete the form $form = arr::overwrite($form, $reply->as_array()); if ($post = $this->input->post()) { // validate and insert the reply if ($reply->edit($post, TRUE)) { url::redirect(url::current()); } $form = arr::overwrite($form, $post->as_array()); $errors = arr::overwrite($errors, $post->errors('reply_errors')); } } else { // user already replied $reason = 3; } } else { // user started the debate $reason = 2; } } else { // user is not logged in. $reason = 1; } $limits = Kohana::config('app/debate.limits'); $page = (int) $this->input->get('page', 1); $offset = ($page > 0) ? ($page - 1) * $limits['replies'] : 0; $replies = ORM::factory('reply')->with('user')->with('choice')->where('replies.debate_id', $id); $this->template->title = $debate->topic; $this->template->debate = $debate; $this->template->body = View::factory('debate/view') ->set('debate', $debate) ->set('replies', $replies->find_all($limits['replies'], $offset)) ->set('pagination', Pagination::factory(array ( 'style' => 'digg', 'items_per_page' => $limits['replies'], 'query_string' => 'page', 'auto_hide' => TRUE, 'total_items' => $total = $replies->count_last_query() )) ) ->set('total', $total); // are we showing the add reply form? if (isset($form, $errors)) { $this->template->body->add_reply_form = View::factory('reply/add_reply_form') ->set('debate', $debate) ->set('form', $form) ->set('errors', $errors); } else { $this->template->body->reason = $reason; } } Heres the view, theres some logic in here that determines what message to show the user. <!-- Add Reply Form --> <?php if (isset($add_reply_form)): ?> <?php echo $add_reply_form; ?> <?php else: ?> <?php switch ($reason) { case 1 : // not logged in, show a message $message = 'Add your ' . html::anchor('login?url=' . url::current(TRUE), '<b>vote</b>') . ' to this discussion'; break; case 2 : // started the debate. dont show a message for that. $message = NULL; break; case 3: // already replied, show a message $message = 'You have already replied to this debate'; break; default: // unknown reason. dont show a message $message = NULL; break; } ?> <?php echo app::show_message($message, 'h2'); ?> <?php endif; ?> <!-- End Add Reply Form --> Should I refactor the add reply logic into another function or something.... It all works, it just seems real sloppy. Thanks

  • exception with Linq to SQL using sdf file

    - by Ben
    Hi, I've set up a project with an SDF local database file and am trying to access it using an LINQ To SQL (".dbml") file. I have used the connection string provided by the sdf file and can instanciate the object with out a problem: thisDataContext = new MyDataContext(GetConnectionString()); However, whenever i try to access any information from it eg var collection = (from MyObject p in thisDataContext.MyTable select p); I get the error - "The table name is not valid. [ Token line number (if known) = 2,Token line offset (if known) = 14,Table name = Person ]" I am using Visual Studio 2008 SP1 .Net 3.5 and SQL 2008 CE. I gather something similar happened for SQL 2005 CE and a Hotfix was released, but i would have thought the fix would have been fixed in this version before release. Does anyone know the fix for this? Thanks

  • How to get rid of previous reflection when reflecting a UIImageView (with changing pictures)?

    - by epale
    Hi everyone, I have managed to use the reflection sample app from apple to create a reflection from a UIImageView. But the problem is that when I change the picture inside the UIImageView, the reflection from the previous displayed picture remains on the screen. The new reflection on the next picture then overlaps the previous reflection. How do I ensure that the previous reflection is removed when I change to the next picture? Thank you so much. I hope my question is not too basic. Here is the codes which i used so far: //reflection self.view.autoresizesSubviews = YES; self.view.userInteractionEnabled = YES; // create the reflection view CGRect reflectionRect = currentView.frame; // the reflection is a fraction of the size of the view being reflected reflectionRect.size.height = reflectionRect.size.height * kDefaultReflectionFraction; // and is offset to be at the bottom of the view being reflected reflectionRect = CGRectOffset(reflectionRect, 0, currentView.frame.size.height); reflectionView = [[UIImageView alloc] initWithFrame:reflectionRect]; // determine the size of the reflection to create NSUInteger reflectionHeight = currentView.bounds.size.height * kDefaultReflectionFraction; // create the reflection image, assign it to the UIImageView and add the image view to the containerView reflectionView.image = [self reflectedImage:currentView withHeight:reflectionHeight]; reflectionView.alpha = kDefaultReflectionOpacity; [self.view addSubview:reflectionView]; //reflection */ Then the codes below are used to form the reflection: CGImageRef CreateGradientImage(int pixelsWide, int pixelsHigh) { CGImageRef theCGImage = NULL; // gradient is always black-white and the mask must be in the gray colorspace CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceGray(); // create the bitmap context CGContextRef gradientBitmapContext = CGBitmapContextCreate(nil, pixelsWide, pixelsHigh, 8, 0, colorSpace, kCGImageAlphaNone); // define the start and end grayscale values (with the alpha, even though // our bitmap context doesn't support alpha the gradient requires it) CGFloat colors[] = {0.0, 1.0, 1.0, 1.0}; // create the CGGradient and then release the gray color space CGGradientRef grayScaleGradient = CGGradientCreateWithColorComponents(colorSpace, colors, NULL, 2); CGColorSpaceRelease(colorSpace); // create the start and end points for the gradient vector (straight down) CGPoint gradientStartPoint = CGPointZero; CGPoint gradientEndPoint = CGPointMake(0, pixelsHigh); // draw the gradient into the gray bitmap context CGContextDrawLinearGradient(gradientBitmapContext, grayScaleGradient, gradientStartPoint, gradientEndPoint, kCGGradientDrawsAfterEndLocation); CGGradientRelease(grayScaleGradient); // convert the context into a CGImageRef and release the context theCGImage = CGBitmapContextCreateImage(gradientBitmapContext); CGContextRelease(gradientBitmapContext); // return the imageref containing the gradient return theCGImage; } CGContextRef MyCreateBitmapContext(int pixelsWide, int pixelsHigh) { CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); // create the bitmap context CGContextRef bitmapContext = CGBitmapContextCreate (nil, pixelsWide, pixelsHigh, 8, 0, colorSpace, // this will give us an optimal BGRA format for the device: (kCGBitmapByteOrder32Little | kCGImageAlphaPremultipliedFirst)); CGColorSpaceRelease(colorSpace); return bitmapContext; } (UIImage *)reflectedImage:(UIImageView *)fromImage withHeight:(NSUInteger)height { if (!height) return nil; // create a bitmap graphics context the size of the image CGContextRef mainViewContentContext = MyCreateBitmapContext(fromImage.bounds.size.width, height); // offset the context - // This is necessary because, by default, the layer created by a view for caching its content is flipped. // But when you actually access the layer content and have it rendered it is inverted. Since we're only creating // a context the size of our reflection view (a fraction of the size of the main view) we have to translate the // context the delta in size, and render it. // CGFloat translateVertical= fromImage.bounds.size.height - height; CGContextTranslateCTM(mainViewContentContext, 0, -translateVertical); // render the layer into the bitmap context CALayer *layer = fromImage.layer; [layer renderInContext:mainViewContentContext]; // create CGImageRef of the main view bitmap content, and then release that bitmap context CGImageRef mainViewContentBitmapContext = CGBitmapContextCreateImage(mainViewContentContext); CGContextRelease(mainViewContentContext); // create a 2 bit CGImage containing a gradient that will be used for masking the // main view content to create the 'fade' of the reflection. The CGImageCreateWithMask // function will stretch the bitmap image as required, so we can create a 1 pixel wide gradient CGImageRef gradientMaskImage = CreateGradientImage(1, height); // create an image by masking the bitmap of the mainView content with the gradient view // then release the pre-masked content bitmap and the gradient bitmap CGImageRef reflectionImage = CGImageCreateWithMask(mainViewContentBitmapContext, gradientMaskImage); CGImageRelease(mainViewContentBitmapContext); CGImageRelease(gradientMaskImage); // convert the finished reflection image to a UIImage UIImage *theImage = [UIImage imageWithCGImage:reflectionImage]; // image is retained by the property setting above, so we can release the original CGImageRelease(reflectionImage); return theImage; } */

  • Address of function is not actual code address

    - by mrjoltcola
    Debugging some code in Visual Studio 2008 (C++), I noticed that the address in my function pointer variable is not the actual address of the function itself. This is an extern "C" function. int main() { void (*printaddr)(const char *) = &print; // debug shows printaddr == 0x013C1429 } Address: 0x013C4F10 void print() { ... } The disassembly of taking the function address is: void (*printaddr)(const char *) = &print; 013C7465 C7 45 BC 29 14 3C 01 mov dword ptr [printaddr],offset print (13C1429h) What am I missing?

  • AHCI Driver for own OS

    - by user1496761
    I have been programming a little AHCI driver for two weeks. I have read this article and Intel's Serial ATA Advanced Host Controller Interface (AHCI) 1.3. There is an example, which shows how to read sectors via DMA mode (osdev.org). I have done this operation (ATA_CMD_READ_DMA 0xC8) successfully, but when i tried to write sectors (ATA_CMD_WRITE_DMA 0xCA) to the device, the HBA set the error Offset 30h: PxSERR – Port x Serial ATA Error - Handshake Error (this is decoding from Intel AHCI specification). I don't understand why it happened. Please, help me. In addition, I have tried to issue the command IDENTIFY 0xEC, but not successfully...

  • DataGrid rendering fails

    - by patryk.beza
    I have DataGrid with groups of data. The problem is that after binding data I have strange effect (text was blured by me; the problem are cells' paddings/margins). This effect can be easily 'fixed' by user because after one click on top expander data hides and after second click on the expander, rows in DataGrid are displayed correctly. My XAML code: <DataGrid Name="myDataGrid" Grid.Row="0" ItemsSource="{Binding}" AutoGenerateColumns="False" Background="White" RowBackground="#FBFFFA" AlternatingRowBackground="#EEFAEB" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"> <DataGrid.Columns> <!-- Columns definitions with binding ( . . . ) --> </DataGrid.Columns> <DataGrid.CellStyle> <Style TargetType="{x:Type DataGridCell}"> <Setter Property="Padding" Value="7,3"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type DataGridCell}"> <Border Padding="{TemplateBinding Padding}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True"> <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="Center" /> </Border> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="DataGridCell.IsSelected" Value="True"> <Setter Property="Background"> <Setter.Value> <LinearGradientBrush EndPoint="0.504,1.5" StartPoint="0.504,0.03"> <GradientStop Color="#008C13" Offset="0"/> <GradientStop Color="#19FF38" Offset="0.8"/> </LinearGradientBrush> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> </DataGrid.CellStyle> <DataGrid.GroupStyle> <GroupStyle> <GroupStyle.HeaderTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Path=Name}" FontWeight="Bold" Padding="3" /> </StackPanel> </DataTemplate> </GroupStyle.HeaderTemplate> <GroupStyle.ContainerStyle> <Style TargetType="{x:Type GroupItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type GroupItem}"> <Expander> <Expander.Header> <StackPanel Orientation="Horizontal"> <TextBlock Text="Rok " /> <TextBlock Text="{Binding Name}" /> </StackPanel> </Expander.Header> <ItemsPresenter /> </Expander> </ControlTemplate> </Setter.Value> </Setter> </Style> </GroupStyle.ContainerStyle> </GroupStyle> </DataGrid.GroupStyle> </DataGrid> DataGrid's DataContext is set from code (rows with data in DataGrid are displayed after clicking proper button): ICollectionView myView = CollectionViewSource.GetDefaultView(myList); if (operationsView.GroupDescriptions.Count > 0) operationsView.GroupDescriptions.Clear(); operationsView.GroupDescriptions.Add(new PropertyGroupDescription("myGroupDescProperty")); FinancialIncomeOperationsListDataGrid.DataContext = operationsView; Is there any way to manually update layout of the DataGrid?

  • Linq to SQL and SQL Server Compact Error: "There was an error parsing the query."

    - by Jeremy
    I created a SQL server compact database (MyDatabase.sdf), and populated it with some data. I then ran SQLMetal.exe and generated a linq to sql class (MyDatabase.mdf) Now I'm trying to select all records from a table with a relatively straightforward select, and I get the error: "There was an error parsing the query. [ Token line number = 3,Token line offset = 67,Token in error = MAX]" Here is my select code: public IEnumerable ListItems() { MyDatabase db_m = new MyDatabase("c:\mydatabase.sdf"); return this.db_m.TestTable.Select(test = new Item() { .... } } I've read that Linq to SQL works with Sql Compact, is there some other configuration I need to do?

  • Read and write from a byte stream if the endianess of the data is different from that of the current

    - by Sam Holder
    I have a stream of bytes which contains a flag which identifies the endianness of the data in the header. I want to read the doubles from the stream, which will presumably need to be different if the endianness of the data in the header is different? I am currently using a BinaryReader and calling ReadDouble to read the data from the stream, but if the endianness flag indicates that the data stream has a different endianness than the machine architecture then presumably this will not work? How should this be handled? Should I check the endianness of my data against that of the current machine then when I want to read a double instead read the bytes raw into a byte array and do array.Reverse to reverse the data before using BitConverter.ToDouble () with the reversed data and a zero offset? I could just test this but I do not have a source of data for both endianness so am a bit concerned about creating test data to test the parsing and this being different from what 'real' data might look like.

  • SQL Query with ORDER BY Part 2

    - by Brett
    Hi SQL'ers, This is a followup question to: SQL Query with ORDER BY But I think the SQL logic is going to be quite different, so I am posting it as separate question. I am trying to extend my sql SELECT query it and having some trouble: I have the table: id type radius ------------------------- 1 type1 0.25 2 type2 0.59 3 type1 0.26 4 type1 0.78 5 type3 0.12 6 type2 0.45 7 type3 0.22 8 type3 0.98 and I am trying to learn how to SELECT the second smallest radius for each given type. So the returned recordset should look like: id type radius ------------------------- 3 type1 0.26 2 type2 0.59 7 type3 0.22 (Note: in the referenced question, I was looking for the lowest radius, not the second lowest radius). I am assuming I have to use LIMIT and OFFSET, but if I use the MIN() won't that return a distinct record containing the minimum radius? Does anyone have any thoughts on how to attack this? Many thanks, Brett

  • Why does xdebug crash apache on every XAMPP install I've tried?

    - by Ian Cook
    I've installed the Windows XAMPP package on three separate computers, 2 running Windows Vista 32 bit ( 1 Ultimate / 1 Home Premium ) and 1 running Windows Vista 64 Home Premium. After enabling xdebug in php.ini and restarting apache, viewing the default XAMPP localhost index causes apache to crash in the same way every time, reporting 'php_xdebug.dll' as the Fault Module Name. Here's the full report from the Windows Crash Reporter thing: Problem signature: Problem Event Name: APPCRASH Application Name: apache.exe Application Version: 2.2.9.0 Application Timestamp: 4853f994 Fault Module Name: php_xdebug.dll Fault Module Version: 2.0.3.0 Fault Module Timestamp: 47fcd9b9 Exception Code: c0000005 Exception Offset: 00008493 OS Version: 6.0.6001.2.1.0.768.3 Locale ID: 1033 Additional Information 1: a34a Additional Information 2: c9c5f4fd744690d388ab9d5b3eb051a7 Additional Information 3: cb2e Additional Information 4: 650bb5690556a17e911375b94d3e16f0 I've tried Googling this issue but haven't found any resolution, only reports of similar errors. EDIT: I enabled the extension line for php_xdebug.dll and that seems to have stopped the crashing so far.

  • How do I wait for "animated scroll to id" to complete before focusing on first form field?

    - by codemonkey613
    So, I have a link at the bottom of website. When it is clicked, it scrolls to a form at the top of the page with the animated style. And as it arrives at top of page, it focuses on the first field in form. Currently, this is my code: $(document).ready(function() { $('#goto-show-form').click(function() { $('html, body').animate({scrollTop: $("#show-form").offset().top}, '500'); $('#first-field').focus(); return false; }); }); What happens is it begins scrolling, then focuses to form field while still in process of scrolling, then returns to last position in scrolling process and continues scrolling up. Instead of being smooth, you can see it cuts back and forth. How can I tell jquery to wait until scrolling is complete before focusing to the form field? Here is the website: http://bit.ly/dfjvmT (The link that starts scroll is "Send us your resume" at the bottom.) Thanks.

  • Error when pushing to Heroku - ...appear in group - Ruby on Rails

    - by bgadoci
    I am trying to deploy my first rails app to Heroku and seem to be having a problem. After git push heroku master, and heroku rake db:migrate I get an error saying: SELECT posts.*, count(*) as vote_total FROM "posts" INNER JOIN "votes" ON votes.post_id = posts.id GROUP BY votes.post_id ORDER BY created_at DESC LIMIT 5 OFFSET 0): I have included the full error below and also included the PostControll#index as it seems that is where I am doing the grouping.

  • Cocos2D, UIScrollView, and initial placement of a scene

    - by diatrevolo
    Hello: I am using a UIScrollView to forward touches to Cocos2D as outlined in http://getsetgames.com/2009/08/21/cocos2d-and-uiscrollview/ Everything works great after a few days of working with it, except one thing: when the initial view appears on the screen, the background appears to be scrolled to the center. As soon as I try to scroll around, the image jumps to 0,0, and everything works as normal, except the touches are offset by half the width and height of the background image. Am I overlooking something basic? I can't think of a useful portion of the code that illustrates the issue, as I can't track it down, but would be happy to post code if anyone has any ideas. Thanks in advance, -Roberto

  • Why does the JavaScript need to start with ";" ?

    - by TK
    I have recently noticed that a lot of JavaScript files on the web starts with ; immediately following the comment section. For example, this jQuery plugin's code starts with /** * jQuery.ScrollTo * Copyright (c) 2007-2008 Ariel Flesler - aflesler(at)gmail(dot)com | http://flesler.blogspot.com * Dual licensed under MIT and GPL. * Date: 9/11/2008 .... skipping several lines for brevity... * * @desc Scroll on both axes, to different values * @example $('div').scrollTo( { top: 300, left:'+=200' }, { axis:'xy', offset:-20 } ); */ ;(function( $ ){ Why does the file needs to start with ;? I see this convention on server-side JavaScript files as well. What is an advantage and disadvantage of doing this?

  • Troubleshooting latency spikes on ESXi NFS datastores

    - by exo_cw
    I'm experiencing fsync latencies of around five seconds on NFS datastores in ESXi, triggered by certain VMs. I suspect this might be caused by VMs using NCQ/TCQ, as this does not happen with virtual IDE drives. This can be reproduced using fsync-tester (by Ted Ts'o) and ioping. For example using a Grml live system with a 8GB disk: Linux 2.6.33-grml64: root@dynip211 /mnt/sda # ./fsync-tester fsync time: 5.0391 fsync time: 5.0438 fsync time: 5.0300 fsync time: 0.0231 fsync time: 0.0243 fsync time: 5.0382 fsync time: 5.0400 [... goes on like this ...] That is 5 seconds, not milliseconds. This is even creating IO-latencies on a different VM running on the same host and datastore: root@grml /mnt/sda/ioping-0.5 # ./ioping -i 0.3 -p 20 . 4096 bytes from . (reiserfs /dev/sda): request=1 time=7.2 ms 4096 bytes from . (reiserfs /dev/sda): request=2 time=0.9 ms 4096 bytes from . (reiserfs /dev/sda): request=3 time=0.9 ms 4096 bytes from . (reiserfs /dev/sda): request=4 time=0.9 ms 4096 bytes from . (reiserfs /dev/sda): request=5 time=4809.0 ms 4096 bytes from . (reiserfs /dev/sda): request=6 time=1.0 ms 4096 bytes from . (reiserfs /dev/sda): request=7 time=1.2 ms 4096 bytes from . (reiserfs /dev/sda): request=8 time=1.1 ms 4096 bytes from . (reiserfs /dev/sda): request=9 time=1.3 ms 4096 bytes from . (reiserfs /dev/sda): request=10 time=1.2 ms 4096 bytes from . (reiserfs /dev/sda): request=11 time=1.0 ms 4096 bytes from . (reiserfs /dev/sda): request=12 time=4950.0 ms When I move the first VM to local storage it looks perfectly normal: root@dynip211 /mnt/sda # ./fsync-tester fsync time: 0.0191 fsync time: 0.0201 fsync time: 0.0203 fsync time: 0.0206 fsync time: 0.0192 fsync time: 0.0231 fsync time: 0.0201 [... tried that for one hour: no spike ...] Things I've tried that made no difference: Tested several ESXi Builds: 381591, 348481, 260247 Tested on different hardware, different Intel and AMD boxes Tested with different NFS servers, all show the same behavior: OpenIndiana b147 (ZFS sync always or disabled: no difference) OpenIndiana b148 (ZFS sync always or disabled: no difference) Linux 2.6.32 (sync or async: no difference) It makes no difference if the NFS server is on the same machine (as a virtual storage appliance) or on a different host Guest OS tested, showing problems: Windows 7 64 Bit (using CrystalDiskMark, latency spikes happen mostly during preparing phase) Linux 2.6.32 (fsync-tester + ioping) Linux 2.6.38 (fsync-tester + ioping) I could not reproduce this problem on Linux 2.6.18 VMs. Another workaround is to use virtual IDE disks (vs SCSI/SAS), but that is limiting performance and the number of drives per VM. Update 2011-06-30: The latency spikes seem to happen more often if the application writes in multiple small blocks before fsync. For example fsync-tester does this (strace output): pwrite(3, "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"..., 1048576, 0) = 1048576 fsync(3) = 0 ioping does this while preparing the file: [lots of pwrites] pwrite(3, "********************************"..., 4096, 1036288) = 4096 pwrite(3, "********************************"..., 4096, 1040384) = 4096 pwrite(3, "********************************"..., 4096, 1044480) = 4096 fsync(3) = 0 The setup phase of ioping almost always hangs, while fsync-tester sometimes works fine. Is someone capable of updating fsync-tester to write multiple small blocks? My C skills suck ;) Update 2011-07-02: This problem does not occur with iSCSI. I tried this with the OpenIndiana COMSTAR iSCSI server. But iSCSI does not give you easy access to the VMDK files so you can move them between hosts with snapshots and rsync. Update 2011-07-06: This is part of a wireshark capture, captured by a third VM on the same vSwitch. This all happens on the same host, no physical network involved. I've started ioping around time 20. There were no packets sent until the five second delay was over: No. Time Source Destination Protocol Info 1082 16.164096 192.168.250.10 192.168.250.20 NFS V3 WRITE Call (Reply In 1085), FH:0x3eb56466 Offset:0 Len:84 FILE_SYNC 1083 16.164112 192.168.250.10 192.168.250.20 NFS V3 WRITE Call (Reply In 1086), FH:0x3eb56f66 Offset:0 Len:84 FILE_SYNC 1084 16.166060 192.168.250.20 192.168.250.10 TCP nfs > iclcnet-locate [ACK] Seq=445 Ack=1057 Win=32806 Len=0 TSV=432016 TSER=769110 1085 16.167678 192.168.250.20 192.168.250.10 NFS V3 WRITE Reply (Call In 1082) Len:84 FILE_SYNC 1086 16.168280 192.168.250.20 192.168.250.10 NFS V3 WRITE Reply (Call In 1083) Len:84 FILE_SYNC 1087 16.168417 192.168.250.10 192.168.250.20 TCP iclcnet-locate > nfs [ACK] Seq=1057 Ack=773 Win=4163 Len=0 TSV=769110 TSER=432016 1088 23.163028 192.168.250.10 192.168.250.20 NFS V3 GETATTR Call (Reply In 1089), FH:0x0bb04963 1089 23.164541 192.168.250.20 192.168.250.10 NFS V3 GETATTR Reply (Call In 1088) Directory mode:0777 uid:0 gid:0 1090 23.274252 192.168.250.10 192.168.250.20 TCP iclcnet-locate > nfs [ACK] Seq=1185 Ack=889 Win=4163 Len=0 TSV=769821 TSER=432716 1091 24.924188 192.168.250.10 192.168.250.20 RPC Continuation 1092 24.924210 192.168.250.10 192.168.250.20 RPC Continuation 1093 24.924216 192.168.250.10 192.168.250.20 RPC Continuation 1094 24.924225 192.168.250.10 192.168.250.20 RPC Continuation 1095 24.924555 192.168.250.20 192.168.250.10 TCP nfs > iclcnet_svinfo [ACK] Seq=6893 Ack=1118613 Win=32625 Len=0 TSV=432892 TSER=769986 1096 24.924626 192.168.250.10 192.168.250.20 RPC Continuation 1097 24.924635 192.168.250.10 192.168.250.20 RPC Continuation 1098 24.924643 192.168.250.10 192.168.250.20 RPC Continuation 1099 24.924649 192.168.250.10 192.168.250.20 RPC Continuation 1100 24.924653 192.168.250.10 192.168.250.20 RPC Continuation 2nd Update 2011-07-06: There seems to be some influence from TCP window sizes.

Update 2011-07-31: I can also reproduce this problem on the new ESXi build 4.1.0.433742.

  • jQuery: Highlight element under mouse cursor?

    - by Ralph
    I'm trying to create an "element picker" in jQuery, like Firebug has. Basically, I want to highlight the element underneath the user's mouse. Here's what I've got so far, but it isn't working very well: $('*').mouseover(function (event) { var $this = $(this); $div.offset($this.offset()).width($this.width()).height($this.height()); return false; }); var $div = $('<div>') .css({ 'background-color': 'rgba(255,0,0,.5)', 'position': 'absolute', 'z-index': '65535' }) .appendTo('body'); Basically, I'm injecting a div into the DOM that has a semi-transparent background. Then I listen for the mouseover event on every element, then move the div so that it covers that element. Right now, this just makes the whole page go red as soon as you move your mouse over the page. How can I get this to work nicer? Edit: Pretty sure the problem is that as soon as my mouse touches the page, the body gets selected, and then as I move my mouse around, none of the moments get passed through the highligher because its overtop of everything. Firebug Digging through Firebug source code, I found this: drawBoxModel: function(el) { // avoid error when the element is not attached a document if (!el || !el.parentNode) return; var box = Firebug.browser.getElementBox(el); var windowSize = Firebug.browser.getWindowSize(); var scrollPosition = Firebug.browser.getWindowScrollPosition(); // element may be occluded by the chrome, when in frame mode var offsetHeight = Firebug.chrome.type == "frame" ? FirebugChrome.height : 0; // if element box is not inside the viewport, don't draw the box model if (box.top > scrollPosition.top + windowSize.height - offsetHeight || box.left > scrollPosition.left + windowSize.width || scrollPosition.top > box.top + box.height || scrollPosition.left > box.left + box.width ) return; var top = box.top; var left = box.left; var height = box.height; var width = box.width; var margin = Firebug.browser.getMeasurementBox(el, "margin"); var padding = Firebug.browser.getMeasurementBox(el, "padding"); var border = Firebug.browser.getMeasurementBox(el, "border"); boxModelStyle.top = top - margin.top + "px"; boxModelStyle.left = left - margin.left + "px"; boxModelStyle.height = height + margin.top + margin.bottom + "px"; boxModelStyle.width = width + margin.left + margin.right + "px"; boxBorderStyle.top = margin.top + "px"; boxBorderStyle.left = margin.left + "px"; boxBorderStyle.height = height + "px"; boxBorderStyle.width = width + "px"; boxPaddingStyle.top = margin.top + border.top + "px"; boxPaddingStyle.left = margin.left + border.left + "px"; boxPaddingStyle.height = height - border.top - border.bottom + "px"; boxPaddingStyle.width = width - border.left - border.right + "px"; boxContentStyle.top = margin.top + border.top + padding.top + "px"; boxContentStyle.left = margin.left + border.left + padding.left + "px"; boxContentStyle.height = height - border.top - padding.top - padding.bottom - border.bottom + "px"; boxContentStyle.width = width - border.left - padding.left - padding.right - border.right + "px"; if (!boxModelVisible) this.showBoxModel(); }, hideBoxModel: function() { if (!boxModelVisible) return; offlineFragment.appendChild(boxModel); boxModelVisible = false; }, showBoxModel: function() { if (boxModelVisible) return; if (outlineVisible) this.hideOutline(); Firebug.browser.document.getElementsByTagName("body")[0].appendChild(boxModel); boxModelVisible = true; } Looks like they're using a standard div + css to draw it..... just have to figure out how they're handling the events now... (this file is 28K lines long) There's also this snippet, which I guess retrieves the appropriate object.... although I can't figure out how. They're looking for a class "objectLink-element"... and I have no idea what this "repObject" is. onMouseMove: function(event) { var target = event.srcElement || event.target; var object = getAncestorByClass(target, "objectLink-element"); object = object ? object.repObject : null; if(object && instanceOf(object, "Element") && object.nodeType == 1) { if(object != lastHighlightedObject) { Firebug.Inspector.drawBoxModel(object); object = lastHighlightedObject; } } else Firebug.Inspector.hideBoxModel(); }, I'm thinking that maybe when the mousemove or mouseover event fires for the highlighter node I can somehow pass it along instead? Maybe to node it's covering...?

  • How do I.. get a value for time at 9:00am local, regardless of the timezone?

    - by ander163
    In my app, I need to set a variable for a start time to be 9:00 a.m. local, wherever the user is located. I have a timezone variable for each user and the save and retrieve are all working. But I need to set a variable when I create a new event to be 9:00 am in the user's local time zone. My current method uses the local time of the server, then makes the adjustments for the individual user's time zone. I don't know what I don't know - is there a command to create the value for "Today's date at 9:00 am where you are"? My current code is: t = Time.now.to_date.beginning_of_day + 11.hours (forcing the 2 hour offset between my primary user and the server in a different timezone).

    I am trying to add the SQL_CALC_FOUND_ROWS into a query (Please note this isn't for pagination) please note I am trying to add this to a cakePHP query the code I currently have is below: return $this->find('all', array( 'conditions' => $conditions, 'fields'=>array('SQL_CALC_FOUND_ROWS','Category.*','COUNT(`Entity`.`id`) as `entity_count`'), 'joins' => array('LEFT JOIN `entities` AS Entity ON `Entity`.`category_id` = `Category`.`id`'), 'group' => '`Category`.`id`', 'order' => $sort, 'limit'=>$params['limit'], 'offset'=>$params['start'], 'contain' => array('Domain' => array('fields' => array('title'))) )); Note the 'fields'=>array('SQL_CALC_FOUND_ROWS',' this obviously doesn't work as It tries to apply the SQL_CALC_FOUND_ROWS to the table e.g. SELECTCategory.SQL_CALC_FOUND_ROWS, Is there anyway of doing this? Any help would be greatly appreciated, thanks.

  • How to zoom in google map (J2ME)

    - by Nivek
    Hi all, I am trying to develop a J2ME application that could retrieve the google map by passing in the GPS coordinates. From http://wiki.forum.nokia.com/index.php/Google_Maps_API_in_Java_ME, it provides the Utility method for map scrolling. Basically it states that i need to include MicroFloat library in my project. Here's what i did (Not sure if i am doing it right) Create a project, build the code. Add the jar file into my current project lib. but i am still getting error from codes. Example double LToY(double y) { return Math.round( offset - radius * Double.longBitsToDouble(MicroDouble.log( Double.doubleToLongBits( (1 + Math.sin(Math.toRadians(y))) / (1 - Math.sin(Math.toRadians(y))) ) )) / 2); } Am i missing any import statment??? Btw i am using netbeans 6.5. Thanks for any guidance... Kevin

  • Are there any syntax errors in the code snippet here?

    - by Mask
    typedef union YYSTYPE { int64_t iConst; // constant value float fConst; // constant value int iAttrLocator; // attribute locator (rowitem for int/float; offset+size for bits) int iFunc; // function id int iNode; // node index } YYSTYPE; It looks valid to me,but the cdt reports the following for the line int64_t iConst;: Multiple markers at this line: - syntax error before "int64_t" - no semicolon at the end of structure or union There are two files that defines int64_t,one is within the project itself(sphinxstd.h),the other is the MinGW/include/stdint.h,is it caused by this conflict?
