• Alternatives to Pessimistic Locking in Cluster Applications

  - by amphibient

  I am researching alternatives to database-level pessimistic locking to achieve transaction isolation in a cluster of Java applications going against the same database. Synchronizing concurrent access in the application tier is clearly not a solution in the present configuration because the same database transaction can be invoked from multiple JVMs concurrently. Currently, we are subject to occasional race conditions which, due to the optimistic locking we have in place via Hibernate, cause a StaleObjectStateException exception and data loss. I have a moderately large transaction within the scope of my refactoring project. Let's describe it as updating one top-level table row and then making various related inserts and/or updates to several of its child entities. I would like to insure exclusive access to the top-level table row and all of the children to be affected but I would like to stay away from pessimistic locking at the database level for performance reasons mostly. We use Hibernate for ORM. Does it make sense to start a single (perhaps synchronous) message queue application into which this method could be moved to insure synchronized access as opposed to each cluster node using its own, which is a clear race condition hazard? I am mentioning this approach even though I am not confident in it because both the top-level table row and its children could also be updated from other system calls, not just the mentioned transaction. So I am seeking to design a solution where the top-level table row and its children will all somehow be pseudo-locked (exclusive transaction isolation) but at the application and not the database level. I am open to ideas and suggestions, I understand this is not a very cut and dried challenge.

• Best way to implement a simple bullet trajectory

  - by AirieFenix

  I searched and searched and although it's a fair simple question, I don't find the proper answer but general ideas (which I already have). I have a top-down game and I want to implement a gun which shoots bullets that follow a simple path (no physics nor change of trajectory, just go from A to B thing). a: vector of the position of the gun/player. b: vector of the mouse position (cross-hair). w: the vector of the bullet's trajectory. So, w=b-a. And the position of the bullet = [x=x0+speed*time*normalized w.x , y=y0+speed*time * normalized w.y]. I have the constructor: public Shot(int shipX, int shipY, int mouseX, int mouseY) { //I get mouse with Gdx.input.getX()/getY() ... this.shotTime = TimeUtils.millis(); this.posX = shipX; this.posY = shipY; //I used aVector = aVector.nor() here before but for some reason didn't work float tmp = (float) (Math.pow(mouseX-shipX, 2) + Math.pow(mouseY-shipY, 2)); tmp = (float) Math.sqrt(Math.abs(tmp)); this.vecX = (mouseX-shipX)/tmp; this.vecY = (mouseY-shipY)/tmp; } And here I update the position and draw the shot: public void drawShot(SpriteBatch batch) { this.lifeTime = TimeUtils.millis() - this.shotTime; //position = positionBefore + v*t this.posX = this.posX + this.vecX*this.lifeTime*speed*Gdx.graphics.getDeltaTime(); this.posY = this.posY + this.vecY*this.lifeTime*speed*Gdx.graphics.getDeltaTime(); ... } Now, the behavior of the bullet seems very awkward, not going exactly where my mouse is (it's like the mouse is 30px off) and with a random speed. I know I probably need to open the old algebra book from college but I'd like somebody says if I'm in the right direction (or points me to it); if it's a calculation problem, a code problem or both. Also, is it possible that Gdx.input.getX() gives me non-precise position? Because when I draw the cross-hair it also draws off the cursor position. Sorry for the long post and sorry if it's a very basic question. Thanks!

• Ubuntu Unity (64-bit) Bugs on Nvidia dual screen [closed]

  - by Kristofer

  On my work computer I have upgraded 10.04 to 10.10 and now to 11.04. Upgrades have mostly worked well and the dual screen setup is almost working. There are however a couple of annoying bugs which I tried to report but the bug reporting tool told me to ask about the bugs here. Here's what I have found: Auto-hide stops working. It doesn't seem to matter which application is maximised/covering the dock, it just stays on top. I have tested changing the autohide settings with no result. Scenario: One maximised window on each screen. If I now try to drag the window that doesn't have focus by dragging the top of the window nothing happens. I can also not give the window focus by clicking the top bar, I have to click inside the window and then I can drag the window. If I unmaximise the window with focus it does work and I can both change focus and drag the window directly by clicking the top of the maximised window. Any bug fixes coming for these issues? Any work-arounds?

• Are these non-standard applications of rendering practical in games?

  - by maul

  I've recently got into 3D and I came up with a few different "tricky" rendering techniques. Unfortunately I don't have the time to work on this myself, but I'd like to know if these are known methods and if they can be used in practice. Hybrid rendering Now I know that ray-tracing is still not fast enough for real-time rendering, at least on home computers. I also know that hybrid rendering (a combination of rasterization and ray-tracing) is a well known theory. However I had the following idea: one could separate a scene into "important" and "not important" objects. First you render the "not important" objects using traditional rasterization. In this pass you also render the "important" objects using a special shader that simply marks these parts on the image using a special color, or some stencil/depth buffer trickery. Then in the second pass you read back the results of the first pass and start ray tracing, but only from the pixels that were marked by the "important" object's shader. This would allow you to only ray-trace exactly what you need to. Could this be fast enough for real-time effects? Rendered physics I'm specifically talking about bullet physics - intersection of a very small object (point/bullet) that travels across a straight line with other, relatively slow-moving, fairly constant objects. More specifically: hit detection. My idea is that you could render the scene from the point of view of the gun (or the bullet). Every object in the scene would draw a different color. You only need to render a 1x1 pixel window - the center of the screen (again, from the gun's point of view). Then you simply check that central pixel and the color tells you what you hit. This is pixel-perfect hit detection based on the graphical representation of objects, which is not common in games. Afaik traditional OpenGL "picking" is a similar method. This could be extended in a few ways: For larger (non-bullet) objects you render a larger portion of the screen. If you put a special-colored plane in the middle of the scene (exactly where the bullet will be after the current frame) you get a method that works as the traditional slow-moving iterative physics test as well. You could simulate objects that the bullet can pass through (with decreased velocity) using alpha blending or some similar trick. So are these techniques in use anywhere, and/or are they practical at all?

• Internet Marketing Consultant Engagement

  I heard a great line from a colleague a while back say he has seen so many times where the consultant says I have the experience and the business owner had the money, when the relationship was over it seems like the consultant had the money and the business owner had the "experience." How many business owners do you think have been there before? This is why so many business owners are gun shy in dealing with internet marketing and marketing in general.

• PHP script keeps doing mmap/munmap

  - by Aurélien Momow

  Hello, My PHP script contains a loop, which does nothing much more than echoing and dereferencing pointers (like in $tab[$othertab[$i]]- stuff). It was working great until yesterday, when this script starting being VERY slow (like 50 times slower than before). After using strace, i figured out that 90% of the time, the script does mmap/munmap. Here is a random portion of the strace log : mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 munmap(0x7fac0156c000, 266240) = 0 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0152b000 mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac014ea000 Here is the result of the strace -c command : % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 82.77 0.004092 0 13542 mmap 9.69 0.000479 0 3642 write 7.54 0.000373 0 13541 munmap 0.00 0.000000 0 100 read 0.00 0.000000 0 88 poll 0.00 0.000000 0 25 4 access ------ ----------- ----------- --------- --------- ---------------- 100.00 0.004944 30938 4 total Here is the php script : function affAnnonce($tabAnnonces, $isDoublon = 0) { GLOBAL $db, $base, $tabDomaine, $doublon, $traduction, $tab_contrat, $tab_emploi, $tab_categ, $tab_metier, $tab_region, $tab_departement, $tab_secteur, $tab_experience, $calc_all, $tabLangues, $tabLanguesNiveau, $tabNoAffAnnonce, $tabHisto; foreach($tabAnnonces AS $tmp) { if (in_array($tmp['id'], $tabNoAffAnnonce) === true) { continue; } $value->host = "../"; foreach($tabDomaine AS $domaine => $valeur) { if ($domaine == $tmp['domaine']) { $value->host = $valeur->host; break; } } // Ordre // secteur;metier;contrat;emploi;region;langues;domaine $tabPushModif = array(); if ($tmp['push_preview'] != '') { $tabPushModif = explode(';', $tmp['push_preview']); $tabPushModif['secteur'] = $tabPushModif[0]; $tabPushModif['metier'] = $tabPushModif[1]; $tabPushModif['contrat'] = $tabPushModif[2]; $tabPushModif['id_emploi'] = $tabPushModif[3]; $tabPushModif['regions'] = $tabPushModif[4]; $tabPushModif['langues'] = $tabPushModif[5]; $tabPushModif['domaine'] = $tabPushModif[6]; } $infoSoc = get_nom_societe($tmp['id_societe']); $number = ($tmp['nb_preview_push'] != '' ? $tmp['nb_preview_push'] : '&nbsp;'); $secteurs = explode ("/", $tmp[secteur]); $sector = ""; $count_sect = count($secteurs); for ($k = 0; $k < $count_sect; $k++) { if ($secteurs[$k] != '') { $sector .= $tab_secteur[$secteurs[$k]].'/'; } } $tmp['poste'] = apresinsertion($tmp['poste']); $tmp['metier'] = $tab_metier[$tmp['metier']]; $tmp['region'] = $tab_region[$tmp['region']]; $tmp['departement'] = $tab_departement[$tmp['departement']]; $tmp['secteur'] = $sector; $tmp['id_contrat'] = $tmp['contrat']; $tmp['contrat'] = $tab_contrat[$tmp['contrat']]; $tmp['emploi'] = $tab_emploi[$tmp['id_emploi']]; $tmp['categorie'] = $tab_categ[$tmp['categorie']]; echo '<tr id="'.($isDoublon ?

• Pyramind of DIVs

  - by sebastian

  Hi there, I'm trying to build a pyramid that's made of 4 DIVs. The layout looks like this: ------ | #1 | ------ ---------------- | #2 | #3 | #4 | ---------------- Moreover I need 3 additional DIVs starting at the center DIV (#3) and containing either #1, #2 or #3 additionally. These DIVs are used the build a sliding effect with jQueryUI later on. It's supposed to look like #1, #2 and #4 slide out of #3. The margin between the DIVs is supposed to be 2 pixels. I also want the whole block to be centered. Even with display: inline; and position: absolute; enabled on the visible and invisible DIVs I can't get the layout right. I used some negative margins and when it looked ok for the first time I saw that my top DIV was positioned outside of the html body. I suppose there is a more simple and elegant way to achieve what I want. Thanks in advance Sebastian Here's what I've got so far: HTML: <div id="centerbox"> <div id="main">main</div> <div id="rail_top"> <div id="top">top</div> </div> <div id="rail_left"> <div id="left">left</div> </div> <div id="rail_right"> <div id="right">right</div> </div> </div> CSS: #centerbox { height: 602px; width: 904px; margin-top: 640px; margin-left: auto; margin-right: auto; } /* blue */ #main { background-color: #33F; height: 300px; width: 300px; margin: 2px; z-index: 9999; position: absolute; display: inline; margin-left: 302px; } /* green */ #top { background-color: #3F0; height: 300px; width: 300px; z-index: 1; position: absolute; display: inline; } /* pink */ #left { background-color: #F06; height: 300px; width: 300px; z-index: 1; } /* orange */ #right { background-color: #FC0; height: 300px; width: 300px; z-index: 1; margin-left: 302px; } #rail_top { height: 602px; width: 300px; display: inline; position: absolute; margin-top: -300px; margin-left: 302px; } #rail_left { height: 300px; width: 602px; float: left; position: absolute; display: inline; margin-top: 2px; } #rail_right { height: 300px; width: 602px; float: right; position: absolute; display: inline; margin-left: 302px; margin-top: 2px; }

• How the JOptionPane works

  - by DevAno1

  How can I control what happens with window after clicking JOPtionPane buttons ? I'm trying to implement simple file chooser. In my frame I have 3 buttons (OK, Cancel, Browse). Browse button opens file search window, and after picking files should return to main frame. Clicking OK will open a frame with the content of the file. Now porblem looks this way. With the code below, I can choose file but directly after that a new frame is created, and my frame with buttons dissapears : import java.io.File; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.awt.*; import javax.swing.*; import java.io.*; public class Main { public static void main(String args[]) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { show("Window"); } }); } public static void show(String frame_name){ JFrame frame = new JFrame(frame_name); frame.setPreferredSize(new Dimension(450, 300)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel top = new JPanel(); top.setLayout(new BoxLayout(top, BoxLayout.Y_AXIS)); JFileChooser fc = new JFileChooser(new File(".")); JPanel creator = new JPanel(); creator.setLayout(new BoxLayout(creator, BoxLayout.Y_AXIS)); creator.add(top); String[] buttons = {"OK", "Cancel", "Browse"}; int rc = JOptionPane.showOptionDialog( null, creator, frame_name, JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, buttons, buttons[0] ); String approveButt = ""; switch(rc){ case 0: break; case 1: break; case 2: approveButt = buttons[rc]; int retVal = fc.showDialog(null, approveButt); if (retVal == JFileChooser.APPROVE_OPTION) System.out.println(approveButt + " " + fc.getSelectedFile()); break; } frame.pack(); frame.setVisible(true); } } With the second code I can return to my menu, but in no way I am able to pop this new frame, which appeared with first code. How to control this ? What am I missing ? public class Main { public static void main(String args[]) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { show("Window"); } }); } public static void show(String frame_name){ JFrame frame = new JFrame(frame_name); frame.setPreferredSize(new Dimension(450, 300)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel top = new JPanel(); top.setLayout(new BoxLayout(top, BoxLayout.Y_AXIS)); JFileChooser fc = new JFileChooser(new File(".")); JPanel creator = new JPanel(); creator.setLayout(new BoxLayout(creator, BoxLayout.Y_AXIS)); creator.add(top); String[] buttons = {"OK", "Cancel", "Browse"}; String approveButt = ""; Plane m = null; int rc = -1; while (rc != 0) { rc = JOptionPane.showOptionDialog( null, creator, frame_name, JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, buttons, buttons[0] ); switch (rc) { case 0: m = new Plane(); case 1: System.exit(0); case 2: approveButt = buttons[rc]; int retVal = fc.showDialog(null, approveButt); if (retVal == JFileChooser.APPROVE_OPTION) System.out.println(approveButt + " " + fc.getSelectedFile()); break; default: break; } } addComponents(frame.getContentPane(), m); frame.pack(); frame.setVisible(true); } private static void addComponents(Container c, Plane e) { c.setLayout(new BoxLayout(c, BoxLayout.Y_AXIS)); c.add(e); } } class Plane extends JPanel { public Plane(){ } @Override public void paint(Graphics g){ g.setColor(Color.BLUE); g.fillRect(0, 0, 400, 250); } }

• Rogue PropertyChanged notifications from ViewModel

  - by user1886323

  The following simple program is causing me a Databinding headache. I'm new to this which is why I suspect it has a simple answer. Basically, I have two text boxes bound to the same property myString. I have not set up the ViewModel (simply a class with one property, myString) to provide any notifications to the View for when myString is changed, so even although both text boxes operate a two way binding there should be no way that the text boxes update when myString is changed, am I right? Except... In most circumstances this is true - I use the 'change value' button at the bottom of the window to change the value of myString to whatever the user types into the adjacent text box, and the two text boxes at the top, even although they are bound to myString, do not change. Fine. However, if I edit the text in TextBox1, thus changing the value of myString (although only when the text box loses focus due to the default UpdateSourceTrigger property, see reference), TextBox2 should NOT update as it shouldn't receive any updates that myString has changed. However, as soon as TextBox1 loses focus (say click inside TextBox2) TextBox2 is updated with the new value of myString. My best guess so far is that because the TextBoxes are bound to the same property, something to do with TextBox1 updating myString gives TextBox2 a notification that it has changed. Very confusing as I haven't used INotifyPropertyChanged or anything like that. To clarify, I am not asking how to fix this. I know I could just change the binding mode to a oneway option. I am wondering if anyone can come up with an explanation for this strange behaviour? ViewModel: namespace WpfApplication1 { class ViewModel { public ViewModel() { _myString = "initial message"; } private string _myString; public string myString { get { return _myString; } set { if (_myString != value) { _myString = value; } } } } } View: <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="MainWindow" Height="350" Width="525"> <Window.DataContext> <local:ViewModel /> </Window.DataContext> <Grid> <!-- The culprit text boxes --> <TextBox Height="23" HorizontalAlignment="Left" Margin="166,70,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding Path=myString, Mode=TwoWay}" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="166,120,0,0" Name="textBox2" VerticalAlignment="Top" Width="120" Text="{Binding Path=myString, Mode=TwoWay}"/> <!--The buttons allowing manual change of myString--> <Button Name="changevaluebutton" Content="change value" Click="ButtonUpdateArtist_Click" Margin="12,245,416,43" Width="75" /> <Button Content="Show value" Height="23" HorizontalAlignment="Left" Margin="12,216,0,0" Name="showvaluebutton" VerticalAlignment="Top" Width="75" Click="showvaluebutton_Click" /> <Label Content="" Height="23" HorizontalAlignment="Left" Margin="116,216,0,0" Name="showvaluebox" VerticalAlignment="Top" Width="128" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="116,245,0,0" Name="changevaluebox" VerticalAlignment="Top" Width="128" /> <!--simply some text--> <Label Content="TexBox1" Height="23" HorizontalAlignment="Left" Margin="99,70,0,0" Name="label1" VerticalAlignment="Top" Width="61" /> <Label Content="TexBox2" Height="23" HorizontalAlignment="Left" Margin="99,118,0,0" Name="label2" VerticalAlignment="Top" Width="61" /> </Grid> </Window> Code behind for view: namespace WpfApplication1 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { ViewModel viewModel; public MainWindow() { InitializeComponent(); viewModel = (ViewModel)this.DataContext; } private void showvaluebutton_Click(object sender, RoutedEventArgs e) { showvaluebox.Content = viewModel.myString; } private void ButtonUpdateArtist_Click(object sender, RoutedEventArgs e) { viewModel.myString = changevaluebox.Text; } } }

• How to hide jQuery Sub-Menus(ddsmoothmenu)?

  - by Tim

  I'm new to jQuery and i must admit that i've understood nothing yet, the syntax appears to me as an unknown language although i thought that i had my experiences with javascript. Nevertheless i managed it to implement this menu in my asp.net masterpage's header. Even got it to work that the content-page is loaded with ajax with help from here. But finally i'm failing with the menu to disappear when the new page was loaded asynchronously. I dont know how to hide this accursed jQuery Menu. Following the part of the js-file where the events are registered for hiding/disappearing. I dont know how to get the part that is responsible for it and even i dont know how to implement that part in my Anchor-onclick function where i dont have a reference to the jQuery Object. buildmenu:function($, setting){ var smoothmenu=ddsmoothmenu var $mainmenu=$("#"+setting.mainmenuid+">ul") //reference main menu UL $mainmenu.parent().get(0).className=setting.classname || "ddsmoothmenu" var $headers=$mainmenu.find("ul").parent() $headers.hover( function(e){ $(this).children('a:eq(0)').addClass('selected') }, function(e){ $(this).children('a:eq(0)').removeClass('selected') } ) $headers.each(function(i){ //loop through each LI header var $curobj=$(this).css({zIndex: 100-i}) //reference current LI header var $subul=$(this).find('ul:eq(0)').css({display:'block'}) $subul.data('timers', {}) this._dimensions={w:this.offsetWidth, h:this.offsetHeight, subulw:$subul.outerWidth(), subulh:$subul.outerHeight()} this.istopheader=$curobj.parents("ul").length==1? true : false //is top level header? $subul.css({top:this.istopheader && setting.orientation!='v'? this._dimensions.h+"px" : 0}) $curobj.children("a:eq(0)").css(this.istopheader? {paddingRight: smoothmenu.arrowimages.down[2]} : {}).append( //add arrow images '<img src="'+ (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[1] : smoothmenu.arrowimages.right[1]) +'" class="' + (this.istopheader && setting.orientation!='v'? smoothmenu.arrowimages.down[0] : smoothmenu.arrowimages.right[0]) + '" style="border:0;" />' ) if (smoothmenu.shadow.enable){ this._shadowoffset={x:(this.istopheader?$subul.offset().left+smoothmenu.shadow.offsetx : this._dimensions.w), y:(this.istopheader? $subul.offset().top+smoothmenu.shadow.offsety : $curobj.position().top)} //store this shadow's offsets if (this.istopheader) $parentshadow=$(document.body) else{ var $parentLi=$curobj.parents("li:eq(0)") $parentshadow=$parentLi.get(0).$shadow } this.$shadow=$('<div class="ddshadow'+(this.istopheader?

Thanks, Tim EDIT: thanks to Starx' private-lesson in jQuery for beginners i solved it: I forgot the # in $("#smoothmenu1"). After that it was not difficult to find and call the hover-function from the menu's headers to let them fade out smoothly: $("#smoothmenu1").find("ul").hover(); Regards, Tim

• How to archive data from a table to a local or remote database in SQL 2005 and SQL 2008

  - by simonsabin

  Often you have the need to archive data from a table. This leads to a number of challenges 1. How can you do it without impacting users 2. How can I make it transactionally consistent, i.e. the data I put in the archive is the data I remove from the main table 3. How can I get it to perform well Points 1 is very much tied to point 3. If it doesn't perform well then the delete of data is going to cause lots of locks and thus potentially blocking. For points 1 and 3 refer to my previous posts DELETE-TOP-x-rows-avoiding-a-table-scan and UPDATE-and-DELETE-TOP-and-ORDER-BY---Part2. In essence you need to be removing small chunks of data from your table and you want to do that avoiding a table scan. So that deals with the delete approach but archiving is about inserting that data somewhere else. Well in SQL 2008 they introduced a new feature INSERT over DML (Data Manipulation Language, i.e. SQL statements that change data), or composable DML. The ability to nest DML statements within themselves, so you can past the results of an insert to an update to a merge. I've mentioned this before here SQL-Server-2008---MERGE-and-optimistic-concurrency. This feature is currently limited to being able to consume the results of a DML statement in an INSERT statement. There are many restrictions which you can find here http://msdn.microsoft.com/en-us/library/ms177564.aspx look for the section "Inserting Data Returned From an OUTPUT Clause Into a Table" Even with the restrictions what we can do is consume the OUTPUT from a DELETE and INSERT the results into a table in another database. Note that in BOL it refers to not being able to use a remote table, remote means a table on another SQL instance. To show this working use this SQL to setup two databases foo and fooArchive create database foo go --create the source table fred in database foo select * into foo..fred from sys.objects go create database fooArchive go if object_id('fredarchive',DB_ID('fooArchive')) is null begin     select getdate() ArchiveDate,* into fooArchive..FredArchive from sys.objects where 1=2       end go And then we can use this simple statement to archive the data insert into fooArchive..FredArchive select getdate(),d.* from (delete top (1)         from foo..Fred         output deleted.*) d         go In this statement the delete can be any delete statement you wish so if you are deleting by ids or a range of values then you can do that. Refer to the DELETE-TOP-x-rows-avoiding-a-table-scan post to ensure that your delete is going to perform. The last thing you want to do is to perform 100 deletes each with 5000 records for each of those deletes to do a table scan. For a solution that works for SQL2005 or if you want to archive to a different server then you can use linked servers or SSIS. This example shows how to do it with linked servers. [ONARC-LAP03] is the source server. begin transaction insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*') d commit transaction and to prove the transactions work try, you should get the same number of records before and after. select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive   begin transaction insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*') d rollback transaction   select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive The transactions are very important with this solution. Look what happens when you don't have transactions and an error occurs   select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive   insert into fooArchive..FredArchive select getdate(),d.* from openquery ([ONARC-LAP03],'delete top (1)                     from foo..Fred                     output deleted.*                     raiserror (''Oh doo doo'',15,15)') d                     select (select count(1) from foo..Fred) fred        ,(select COUNT(1) from fooArchive..FredArchive ) fredarchive Before running this think what the result would be. I got it wrong. What seems to happen is that the remote query is executed as a transaction, the error causes that to rollback. However the results have already been sent to the client and so get inserted into the

• Writing to XML issue Unity3D C#

  - by N0xus

  I'm trying to create a tool using Unity to generate an XML file for use in another project. Now, please, before someone suggests I do it in something, the reason I am using Unity is that it allows me to easily port this to an iPad or other device with next to no extra development. So please. Don't suggest to use something else. At the moment, I am using the following code to write to my XML file. public void WriteXMLFile() { string _filePath = Application.dataPath + @"/Data/HV_DarkRideSettings.xml"; XmlDocument _xmlDoc = new XmlDocument(); if (File.Exists(_filePath)) { _xmlDoc.Load(_filePath); XmlNode rootNode = _xmlDoc.CreateElement("Settings"); // _xmlDoc.AppendChild(rootNode); rootNode.RemoveAll(); XmlElement _cornerNode = _xmlDoc.CreateElement("Screen_Corners"); _xmlDoc.DocumentElement.PrependChild(_cornerNode); #region Top Left Corners XYZ Values // indent top left corner value to screen corners XmlElement _topLeftNode = _xmlDoc.CreateElement("Top_Left"); _cornerNode.AppendChild(_topLeftNode); // set the XYZ of the top left values XmlElement _topLeftXNode = _xmlDoc.CreateElement("TopLeftX"); XmlElement _topLeftYNode = _xmlDoc.CreateElement("TopLeftY"); XmlElement _topLeftZNode = _xmlDoc.CreateElement("TopLeftZ"); // indent these values to the top_left value in XML _topLeftNode.AppendChild(_topLeftXNode); _topLeftNode.AppendChild(_topLeftYNode); _topLeftNode.AppendChild(_topLeftZNode); #endregion #region Bottom Left Corners XYZ Values // indent top left corner value to screen corners XmlElement _bottomLeftNode = _xmlDoc.CreateElement("Bottom_Left"); _cornerNode.AppendChild(_bottomLeftNode); // set the XYZ of the top left values XmlElement _bottomLeftXNode = _xmlDoc.CreateElement("BottomLeftX"); XmlElement _bottomLeftYNode = _xmlDoc.CreateElement("BottomLeftY"); XmlElement _bottomLeftZNode = _xmlDoc.CreateElement("BottomLeftZ"); // indent these values to the top_left value in XML _bottomLeftNode.AppendChild(_bottomLeftXNode); _bottomLeftNode.AppendChild(_bottomLeftYNode); _bottomLeftNode.AppendChild(_bottomLeftZNode); #endregion #region Bottom Left Corners XYZ Values // indent top left corner value to screen corners XmlElement _bottomRightNode = _xmlDoc.CreateElement("Bottom_Right"); _cornerNode.AppendChild(_bottomRightNode); // set the XYZ of the top left values XmlElement _bottomRightXNode = _xmlDoc.CreateElement("BottomRightX"); XmlElement _bottomRightYNode = _xmlDoc.CreateElement("BottomRightY"); XmlElement _bottomRightZNode = _xmlDoc.CreateElement("BottomRightZ"); // indent these values to the top_left value in XML _bottomRightNode.AppendChild(_bottomRightXNode); _bottomRightNode.AppendChild(_bottomRightYNode); _bottomRightNode.AppendChild(_bottomRightZNode); #endregion _xmlDoc.Save(_filePath); } } This generates the following XML file: <Settings> <Screen_Corners> <Top_Left> <TopLeftX /> <TopLeftY /> <TopLeftZ /> </Top_Left> <Bottom_Left> <BottomLeftX /> <BottomLeftY /> <BottomLeftZ /> </Bottom_Left> <Bottom_Right> <BottomRightX /> <BottomRightY /> <BottomRightZ /> </Bottom_Right> </Screen_Corners> </Settings> Which is exactly what I want. However, each time I press the button that has the WriteXMLFile() method attached to it, it's write the entire lot again. Like so: <Settings> <Screen_Corners> <Top_Left> <TopLeftX /> <TopLeftY /> <TopLeftZ /> </Top_Left> <Bottom_Left> <BottomLeftX /> <BottomLeftY /> <BottomLeftZ /> </Bottom_Left> <Bottom_Right> <BottomRightX /> <BottomRightY /> <BottomRightZ /> </Bottom_Right> </Screen_Corners> <Screen_Corners> <Top_Left> <TopLeftX /> <TopLeftY /> <TopLeftZ /> </Top_Left> <Bottom_Left> <BottomLeftX /> <BottomLeftY /> <BottomLeftZ /> </Bottom_Left> <Bottom_Right> <BottomRightX /> <BottomRightY /> <BottomRightZ /> </Bottom_Right> </Screen_Corners> <Screen_Corners> <Top_Left> <TopLeftX /> <TopLeftY /> <TopLeftZ /> </Top_Left> <Bottom_Left> <BottomLeftX /> <BottomLeftY /> <BottomLeftZ /> </Bottom_Left> <Bottom_Right> <BottomRightX /> <BottomRightY /> <BottomRightZ /> </Bottom_Right> </Screen_Corners> </Settings> Now, I've written XML files before using winforms, and the WriteXMLFile function is exactly the same. However, in my winform, no matter how much I press the WriteXMLFile button, it doesn't write the whole lot again. Is there something that I'm doing wrong or should change to stop this from happening?

• Why are pieces of my HTML showing up on the page and breaking it? Is it PHP related?

  - by Jason Rhodes

  I've been building a site in PHP, HTML, CSS, and using a healthy dose of jQuery javascript. The site looks absolutely fine on my Mac browsers, but for some reason, when my client uses PC Safari, she's seeing strange bits of my HTML show up on the page. Here are some (small) screenshot examples: Figure 1: This one is just a closing </li> tag that should've been on the Media li element. Not much harm done, but strange. Figure 2: Here this was part of <div class='submenu'> and since the div tag didn't render properly, the entire contents of that div don't get styled correctly by CSS. Figure 3: This last example shows what should have been <a class='top current' href=... but for some reason half of the HTML tag stops being rendered and just gets printed out.

• Multitask Like a Pro with AquaSnap

  - by Matthew Guay

  Are you tired of shuffling back and forth between windows?  Here’s a handy app that can help you keep all of your windows organized and accessible. AquaSnap is a great free utility that helps you use multiple windows at the same time easily and efficiently.  One of Windows 7’s greatest new features is Aero Snap, which lets you easily view windows side by side by simply dragging windows to side of your screen.  After using Windows 7 for the past year, Aero Snap is one of the features we really miss when using older versions of Windows. With AquaSnap, you now have all of the features of Aero Snap and more in Windows 2000, XP, Vista, and of course Windows 7.  Not only does it give you Aero Snap features, but AquaSnap also gives you more control over your windows to make you more productive. Getting Started AquaSnap is a a free download for Windows 2000, XP, Vista, and 7.  Download the small installer (link below) and install it with the default settings. AquaSnap automatically runs as soon as it is installed, and you will notice a new icon in your system tray. Now you can go ahead and put it to use.  Drag a window to any edge or corner of your desktop, and you will see an icon showing what part of the screen the window will cover. Dragging it to the side of the screen expanded the window to fill the right half of the screen, just like the default Aero Snap in Windows 7.  You can drag the window away to restore it to its former size. AquaSnap works on any corner of the screen too, so you can have 4 windows side-by-side.  We already have 3 windows snapped to the corners, and notice that we’re dragging a fourth window to the bottom right corner. You can also snap windows to the bottom and top of the screen.  Here we have Word snapped to the bottom half of the screen, and we’re dragging Chrome to the top. You can even snap internal windows in Multiple Document Interface (MDI) programs such as Excel.  Here we are snapping a workbook in Excel to the left to view 2 workbooks side-by-side.   Additionally, AquaSnap lets you keep any window always on top.  Simply shake any window, and it will turn semi-transparent and stay on top of all other windows.  Notice the transparent calculator here on top of Excel. All of AquaSnap’s features work great in Windows 2000, XP, and Vista too.  Here we are snapping IE6 to the left of the screen in XP. Here are 3 windows snapped to the sides in XP.  You can mix the snap modes, and have, for instance, two windows on the right side and one window on the left.  This is a great way to maximize productivity if you need more space in one of the windows. Even AquaShake works to keep a window transparent and on top in XP. Settings AquaSnap has a detailed settings dialog where you can tweak it to work exactly like you want.  Simply right-click on its icon in the taskbar, and select Settings. From the first screen, you can choose if you want AquaSnap to start with Windows, and if you want it to show an icon in the system tray.  If you turn off the system tray icon, you can access the AquaSnap settings from Start > All Programs > AquaSnap > Configuration (or simply search for Configuration in Vista or Windows 7). The second tab in settings lets you choose what you want each snapping region to do.  You can also choose two other presets, including AeroSnap (which works just like the default Aero Snap in Windows 7) and AquaSnap simple (which only snaps at the edges of the screen, not the corners). The third tab lets you increase or decrease the opacity of pinned windows when using AquaShake, and also lets you increase or decrease the shaking sensitivity.  Additionally, if you prefer the standard AeroShake functionality, which minimizes all other open windows when you shake a window, you can choose that too. The fourth tab lets you activate an optional feature, AquaGlass.  If you activate this, it will make windows turn transparent when you drag them across the screen.   Finally, the last tab lets you change the color and opacity of the preview rectangle, or simply turn it off. Or, if you want to temporarily turn AquaSnap off, simply right-click on its icon and select Off.  In Windows 7, turning off AquaSnap will restore your standard Windows Aero Snap functionality, and in other version of Windows it will stop letting you snap windows at all.  You can then repeat the steps and select On when you want to use AquaSnap again. Conclusion AquaSnap is a handy tool to make you more productive at your computer.  With a wide variety of useful features, there’s something here for everyone.  Download AquaSnap Similar Articles Productive Geek Tips How to Get Virtual Desktops on Windows XP TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 Out of band Security Update for Internet Explorer 7 Cool Looking Screensavers for Windows SyncToy syncs Files and Folders across Computers on a Network (or partitions on the same drive) If it were only this easy Classic Cinema Online offers 100’s of OnDemand Movies OutSync will Sync Photos of your Friends on Facebook and Outlook

• How to code Umbraco XSLT to retrieve Nodes from unrelated tree

  - by Phil.Wheeler

  I have an Umbraco site for personal use that I want to also use as a blog. I'm trying to put together the XSLT to grab the top three posts from the nodes in the Blog tree (node id = 1063) and display these on a tab page that is incorporated into the front page. The following image illustrates the node hierarchy: With my extremely limited appreciation of XSLT, I'm unable to grab the node ID of the "Blog" id and take the 3 pages below that to display in the "Top Posts" part of my site which is found under the "Frontpage Tabs" node. All the examples I find work with the "current page", which is typically the top-level node, "Personal Site". How should I accomplish this?

• Off center projection

  - by N0xus

  I'm trying to implement the code that was freely given by a very kind developer at the following link: http://forum.unity3d.com/threads/142383-Code-sample-Off-Center-Projection-Code-for-VR-CAVE-or-just-for-fun Right now, all I'm trying to do is bring it in on one camera, but I have a few issues. My class, looks as follows: using UnityEngine; using System.Collections; public class PerspectiveOffCenter : MonoBehaviour { // Use this for initialization void Start () { } // Update is called once per frame void Update () { } public static Matrix4x4 GeneralizedPerspectiveProjection(Vector3 pa, Vector3 pb, Vector3 pc, Vector3 pe, float near, float far) { Vector3 va, vb, vc; Vector3 vr, vu, vn; float left, right, bottom, top, eyedistance; Matrix4x4 transformMatrix; Matrix4x4 projectionM; Matrix4x4 eyeTranslateM; Matrix4x4 finalProjection; ///Calculate the orthonormal for the screen (the screen coordinate system vr = pb - pa; vr.Normalize(); vu = pc - pa; vu.Normalize(); vn = Vector3.Cross(vr, vu); vn.Normalize(); //Calculate the vector from eye (pe) to screen corners (pa, pb, pc) va = pa-pe; vb = pb-pe; vc = pc-pe; //Get the distance;; from the eye to the screen plane eyedistance = -(Vector3.Dot(va, vn)); //Get the varaibles for the off center projection left = (Vector3.Dot(vr, va)*near)/eyedistance; right = (Vector3.Dot(vr, vb)*near)/eyedistance; bottom = (Vector3.Dot(vu, va)*near)/eyedistance; top = (Vector3.Dot(vu, vc)*near)/eyedistance; //Get this projection projectionM = PerspectiveOffCenter(left, right, bottom, top, near, far); //Fill in the transform matrix transformMatrix = new Matrix4x4(); transformMatrix[0, 0] = vr.x; transformMatrix[0, 1] = vr.y; transformMatrix[0, 2] = vr.z; transformMatrix[0, 3] = 0; transformMatrix[1, 0] = vu.x; transformMatrix[1, 1] = vu.y; transformMatrix[1, 2] = vu.z; transformMatrix[1, 3] = 0; transformMatrix[2, 0] = vn.x; transformMatrix[2, 1] = vn.y; transformMatrix[2, 2] = vn.z; transformMatrix[2, 3] = 0; transformMatrix[3, 0] = 0; transformMatrix[3, 1] = 0; transformMatrix[3, 2] = 0; transformMatrix[3, 3] = 1; //Now for the eye transform eyeTranslateM = new Matrix4x4(); eyeTranslateM[0, 0] = 1; eyeTranslateM[0, 1] = 0; eyeTranslateM[0, 2] = 0; eyeTranslateM[0, 3] = -pe.x; eyeTranslateM[1, 0] = 0; eyeTranslateM[1, 1] = 1; eyeTranslateM[1, 2] = 0; eyeTranslateM[1, 3] = -pe.y; eyeTranslateM[2, 0] = 0; eyeTranslateM[2, 1] = 0; eyeTranslateM[2, 2] = 1; eyeTranslateM[2, 3] = -pe.z; eyeTranslateM[3, 0] = 0; eyeTranslateM[3, 1] = 0; eyeTranslateM[3, 2] = 0; eyeTranslateM[3, 3] = 1f; //Multiply all together finalProjection = new Matrix4x4(); finalProjection = Matrix4x4.identity * projectionM*transformMatrix*eyeTranslateM; //finally return return finalProjection; } // Update is called once per frame public void FixedUpdate () { Camera cam = camera; //calculate projection Matrix4x4 genProjection = GeneralizedPerspectiveProjection( new Vector3(0,1,0), new Vector3(1,1,0), new Vector3(0,0,0), new Vector3(0,0,0), cam.nearClipPlane, cam.farClipPlane); //(BottomLeftCorner, BottomRightCorner, TopLeftCorner, trackerPosition, cam.nearClipPlane, cam.farClipPlane); cam.projectionMatrix = genProjection; } } My error lies in projectionM = PerspectiveOffCenter(left, right, bottom, top, near, far); The debugger states: Expression denotes a `type', where a 'variable', 'value' or 'method group' was expected. Thus, I changed the line to read: projectionM = new PerspectiveOffCenter(left, right, bottom, top, near, far); But then the error is changed to: The type 'PerspectiveOffCenter' does not contain a constructor that takes '6' arguments. For reasons that are obvious. So, finally, I changed the line to read: projectionM = new GeneralizedPerspectiveProjection(left, right, bottom, top, near, far); And the error I get is: is a 'method' but a 'type' was expected. With this last error, I'm not sure what it is I should do / missing. Can anyone see what it is that I'm missing to fix this error?

• Telecomunication SID model and resources [on hold]

  - by andygluk

  There is a SID model well-known in telecom industry. Following this model you define resources as resources owned by your enterprise, and then you build resource-oriented services on top of it and then customer-oriented services and so on... So everything is based on enterprise-owned resources, which you have to identify first. What I am looking for and what I am asking is some alternative to this model, build not on enterprise-owned resources, but on resources sell by enterprise. Say, you are selling licenses for using your products. So instead of building model on top of enterprise resources you may be interested to build it on top of licenses you are selling.

• Maintain proper symbol order when applying an armature in flash

  - by Michael Taufen

  I am trying to animate a character's leg in flash CS 5.5 for a game I am working on. I decided to use the bone tool because it's awesome. The problem I am having, however, is that for my character to be animated properly, the symbols that make up his leg (upper leg, lower leg, and shoe) need to be on top of each other in a specific way (otherwise the shoe looks like its next to the leg, etc). Applying the bones results in the following problem: the first symbol I apply it to is placed in the rear on the armature layer, the next on top of it, and so on, until the final symbol is already on top. I need them to be in the opposite order, but arrange send to back does nothing on the armature layer. How can I fix this? tl;dr: The bone tool is not maintaining the stacking order of my objects, please help. Thanks for helping :).

• What does Avg Position from Google Webmaster really mean

  - by RandomBen

  I have a website I am tracking on Google's Webmaster tools. When I look at the Search queries page it shows me a graph of Impressions and clicks per day. Underneath that there is a table showing specific results. One of the columns is Avg Position. That columns seems to include paid ads. Is that correct, does the Avg Position also include the top result ads(the ads at the top of the search results)? I am asking because the company I work for has a not so common name and whenever I Google it our site is the #1 result 100% of the time. The only thing above it is 1 paid add. When I checkout Webmaster tools I notice that searching for our name returns with us at an Avg Position of 2.0. That seems like it would be only possible if paid top result ads were included in that position. Does anyone know?
