27,316,625 | 0 | Loop through element of a defined size in Jquery? <p>I'm creating an animation for my website where I got different divs containing an image and an aside where I put my text describing something related to the image. The aside is a little bit wider than my picture and what happens is that when I hover it, it slides to the right and has his width increased. </p> <p>When I hover another one the first one goes back to its initial position. So I found a solution that obliged me to naturally loop through all the divs that are not hovered, but the problem now is since every divs (including the one hovered last) is not hovered, they all get the animation (thus creating a visual bug because the aside is placed absolute and behind the image) while i'd like it to be only on the first one. </p> <p>So I thought I should loop through all the divs that are not hovered AND got a defined sized (the one they got after they are behind shown), but I couldnt get it work, neither did I find a solution to loop through elements with the each function... </p> <p>Here is my HTML code : </p> <pre><code> <div class="partenaires-wrapper"> <img src="http://mylor.fr/mauro/wp-content/uploads/2014/08/sharks.png" alt="" width="223" height="138" /> <div class="partenaires-aside"> Sed rutrum elementum odio, ut efficitur magna efficitur sit amet.

Yes, it will take longer (XML is more verbose), but it's not going to be something that the user will notice.</p> <p>The real issue, in my opinion, is support for XML within JavaScript. <a href="http://en.wikipedia.org/wiki/ECMAScript_for_XML" rel="nofollow">E4X</a> is nice, but it isn't supported by Microsoft.

1,565,205 | 0 | How to extend / amend OSGi lifecycle management? <p>I have a modular application that uses OSGi for lifecycle and dependency management. However, some of the bundles require some time after startup to be ready, for example, because they have to acquire data from somewhere. Also, they might be unable to process certain calls during a configuration update, for example a bundle that keeps a connection to a db can't send queries while it is updating the connection parameters.</p> <p>So, it seems to me that a bundle can have more subtle states than those managed by the OSGi container, and since they affect bundle interaction, there needs to be some handling. I can see three basic strategies for doing this:</p> <ul> <li>screw subtlety, and for example put all initialization code into <code>BundleActivator.start()</code>. If it takes forever to acquire that data, well then the bundle just won't be started forever. I'm not 100% sure that this would cover all cases, and it seems slightly wrong.</li> <li>fit my bundles with an additional event system that they use to notify each other of more subtle states like "momentarily unavailable" or "really ready now". This might simply be unnecessary overhead.</li> <li>have the bundle keep its more subtle state changes to itself and just take calls anyway, deferring them internally if necessary. This might not be appropriate when the caller could actually handle unavailability better.</li> </ul> <p><strong>Do you have any general advice on that? Is there even something in OSGi that I could use?</strong></p> |

1,918,219 | 0 | <p>You can have each tab be a real view controller with nib and everything. The only catch is that you must forward on the standard view controller calls you want to receive (viewWillAppear, etc) but it makes the coding much cleaner since you code just as you would for any other view (although for a smaller space). </p> <p>You call each controllers "view" property to get out the view, which you add as a subview of a container view you have under the tabs.</p> |
24,750,005 | 0 | how to retain the animated position in opengl es 2.0 <p>I am doing frame based animation for 300 frames in opengl es 2.0</p> <p>I want a rectangle to translate by +200 pixels in X axis and also scaled up by double (2 units) in the first 100 frames. For example, the initial value (frame 0) of the rectangle's centre point is at 100 pixels (i.e. rectCenterX = 100) on the screen; At 100th frame, rectCenterX = 300 (100 + 200) pixels. Also the rect size is doubled the original size.</p> <p>Then, the animated rectangle has to stay there for the next 100 frames (without any animation). i.e. the rectCenterX = 300 pixels for frames 101 to 200. At 101st frame, rectCenterX = 300 pixels. the rect size is double the original size. At 200th frame, rectCenterX = 300 pixels. the rect size is double the original size.</p> <p>Then, I want the same animated rectangle to translate by +200 pixels in X axis and also scaled down by half (0.5 units) in the last 100 frames. At 300th frame, rectCenterX = 500 pixels.the rect size is again as the original size.</p> <p>I am using simple linear interpolation to calculate the delta-animation value for each frame.</p> <p>In short,</p> <pre><code>Animation-Type Animation-Value Start-Frame End-Frame 1.Translate +200 0 100 2.Scale +2 0 100 3.Translate +200 201 300 4.Scale +0.5 201 300 </code></pre> <p>Pseudo code: The below drawFrame() is executed for 300 times (300 frames) in a loop.</p> <pre><code>float RectMVMatrix[4][4] = {1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 }; // identity matrix int totalframes = 300; float translate-delta; // interpolated translation value for each frame float scale-delta; // interpolated scale value for each frame // The usual code for draw is: void drawFrame(int iCurrentFrame) { // mySetIdentity(RectMVMatrix); // comment this line to retain the animated position. mytranslate(RectMVMatrix, translate-delta, X_AXIS); // to translate the mv matrix in x axis by translate-delta value myscale(RectMVMatrix, scale-delta); // to scale the mv matrix by scale-delta value ... // opengl calls glDrawArrays(...); eglswapbuffers(...); } </code></pre> <p>The above code will work fine for first 100 frames. in order to retain the animated rectangle during the frames 101 to 200, i removed the "mySetIdentity(RectMVMatrix);" in the above drawFrame().</p> <p>Now on entering the drawFrame() for the 2nd frame, the RectMVMatrix will have the animated value of first frame</p> <p>e.g. RectMVMatrix[4][4] = { 1.01, 0, 0, 2, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1 };// 2 pixels translation and 1.01 units scaling after first frame This RectMVMatrix is used for mytranslate() in 2nd frame. The translate function will affect the value of "RectMVMatrix[0][0]". Thus translation affects the scaling values also.</p> <p>Eventually output is getting wrong.</p> <p>How to retain the animated position without affecting the current ModelView matrix?</p> |

4,250,568 | 0 | <p>I use successfully the following procedure to get images with SmartGWT working.</p> <p>At the same level as the <code>client</code> package of your GWT module I create a folder named <code>public</code>. (In Eclipse you cannot create a package named <code>public</code> because this is not a valid package name. You have to create it explicitly as a folder.) This directory with name <code>public</code> is treated special by GWT. The GWT compiler copies all the included content to the resulting main module directory. So I usually create a subdirectory <code>images</code> under <code>public</code> and put all the images belonging to my GWT module in there.</p> <p>For example:</p> <pre><code>com/stuff client Main.java ... public images a.png b.png mainmodule.gwt.xml </code></pre> <p>Then right at the beginning of the entry point I tell SmartGWT to look at the <code>images</code> subdirectory for the images (in this example is <code>mainmodule</code> the name of my main GWT module):</p> <pre><code>public void onModuleLoad() { Page.setAppImgDir("[APP]/mainmodule/images/"); ... } </code></pre> <p>The <code>[APP]</code> part of the path is special SmartGWT syntax.</p> <p>Later I am able to create an IButton like so:</p> <pre><code>final IButton aBtn = new IButton("A Button"); aBtn.setIcon("a.png"); </code></pre> <p>Sometimes it is necessary to create the URL to an image not for SmartGWT but for plain GWT or plain HTML. For these cases you can create the URL with</p> <pre><code>final String bUrl = GWT.getModuleBaseURL() + "images/b.png"; </code></pre> |

In other words, the values associated with select-list expressions aren't available yet.</p> <p>You can use column aliases in the <code>GROUP BY</code>, <code>HAVING</code>, and <code>ORDER BY</code> clauses.

16,993,902 | 0 | <p>IMHO, the concept is wrong. You dont need to use merge-sort here. Try searching for PriorityQueue or actually BinaryHeap in order to solve this task. Secondly, merge sort on linked list is not a good idea since it will not be efficient at all. I think you should totally rework your solution.</p> <p>NB. Just implement the operation YourLinkedList.getByIndex() for convinience, add the size atribute to hold the number of items in the linked list, then create one more linkedList and perform the bottom-up merge-sort like you would do with a simple array.</p> <p>Structures:</p> <pre><code>public class Item { private String word; private Item next; public Item(String word) { this.word = word; } public Item getNext() { return next; } public void setNext(Item next) { this.next = next; } public String getWord() { return word; } public void setWord(String word) { this.word = word; } } </code></pre> <p>Linked List:</p> <pre><code>public class LinkedList { private int size = 0; private Item first = null; public void swapFragment(LinkedList list, int from, int to) { if (from >= 0 && to < size) { list.get(to-from).setNext(this.get(to+1)); if (from > 0) { this.get(from-1).setNext(list.get(0)); } else { this.first = list.get(0); } } } public void addItem(String word) { if (first == null) { first = new Item(word); } else { Item item = first; while (item.getNext() != null) { item = item.getNext(); } item.setNext(new Item(word)); } this.size++; } public Item get(int index) { if (index >= size) { return null; } else { Item item = first; for(int i = 1; i <= index; i++) { item = item.getNext(); } return item; } } public int getSize() { return size; } public void setSize(int size) { this.size = size; } public String toString() { Item item = first; String message = null; if (item != null) { message = item.getWord() + " "; } else { return null; } while (item.getNext() != null) { item = item.getNext(); message = message + item.getWord() + " "; } return message; } } </code></pre> <p>Merge Sort:</p> <pre><code>public class ListMergeSort { public void sort(LinkedList list, int lo, int hi) { if (hi <= lo) { return; } int mid = lo + (hi-lo)/2; sort(list, lo, mid); sort(list, mid+1, hi); merge(list, lo, hi, mid); } private void merge(LinkedList list, int lo, int hi, int mid) { int i = lo; int j = mid+1; LinkedList newList = new LinkedList(); for (int k = lo; k <= hi; k++) { if (i > mid) { newList.addItem(list.get(j).getWord()); j++; } else if (j > hi) { newList.addItem(list.get(i).getWord()); i++; } else if (list.get(i).getWord().compareTo(list.get(j).getWord()) < 0) { newList.addItem(list.get(i).getWord()); i++; } else { newList.addItem(list.get(j).getWord()); j++; } } list.swapFragment(newList, lo, hi); } } </code></pre> <p>Test Class for Strings:</p> <pre><code>import org.junit.*; public class MergeTest { @Test public void testWords() { LinkedList list = new LinkedList(); list.addItem("word"); list.addItem("pipe"); list.addItem("trainer"); list.addItem("stark"); list.addItem("33"); list.addItem("dmitry"); ListMergeSort lms = new ListMergeSort(); lms.sort(list, 0, list.getSize()-1); } } </code></pre> <p>Now you just need to create a class which receives a string as an argument, splits it with String.split() and adds the resulting words into the internal LinkedList datastructure. Then you sort them inside with the merge sort and you get the result.</p> |

37,200,924 | 0 | Update Realm relationship with primary ids <p>Is it possible to update a Realm object's relationships by passing only the ids of the relationships?</p> <p>If I have a <code>Library</code> class that has a <code>List<Books></code> relationship and I wanted to merge two <code>Libraries</code> together, I would presume that could be done like:</p> <pre><code>let bookIds = (firstLibrary.books.toArray() + secondLibrary.books.toArray).map { $0.id } </code></pre> <p>Then I use ObjectMapper & SugarRecord:</p> <pre><code>let changes = ["books": bookIds] Mapper<T>().map(changes, toObject: secondLibrary) let realm = self.realm realm.add(secondLibrary, update: true) </code></pre> <p>But the list of books doesn't get updated.

13,186,580 | 0 | Using boost::ref to indicate intention in coding conventions <p>When functions take non-const refs as arguments, it can create hard-to-read code because at the calling site it is not obvious which inputs might be changed.

6,175,408 | 0 | Is it possible to change mouse cursor when handling drag (from DragOver event)? <p>We need to display a feedback to the user when he drags-in items into our application.

The <code>GiveFeedbackEventArgs</code> allows us to specify <code>UseDefaultCursors</code> property - setting this to false allows us to override the cursor.</p> <p>However, the <code>DragOver</code> event handler argument, which is the equivalent of <code>GiveFeedback</code>, does not have <code>UseDefaultCursors</code> property and changing the cursor from there does not have any effect.</p> <p><strong>Sample (this has no effect):</strong></p> <pre><code>private void browser_DragOver(object sender, DragEventArgs e) { Cursor.Current = Cursors.WaitCursor; } </code></pre> <p>The drag operation originates from outside our app. (for in-app drag, it works using the <code>GiveFeedback</code> event.</p> <p>How to change the cursor when receiving a drag?

316,863 | 0 | <p>One solution that I feel strikes the right balance in the Framework/Roll-your-own dilemma is the use of three key perl modules: <a href="http://cpan.uwinnipeg.ca/htdocs/CGI.pm/CGI.pm.html#ABSTRACT" rel="nofollow noreferrer">CGI.pm</a>, <a href="http://www.tt2.org/" rel="nofollow noreferrer">Template Toolkit</a> , and <a href="http://cpan.uwinnipeg.ca/htdocs/DBI/DBI/FAQ.html#Basic_Information_amp_Information_So" rel="nofollow noreferrer">DBI</a>. With these three modules you can do elegant MVC programming that is easy to write and to maintain.</p> <p>All three modules are very flexible with Template Toolkit (TT) allowing you to output data in html, XML, or even pdf if you need to. You can also include perl logic in TT, even add your database interface there. This makes your CGI scripts very small and easy to maintain, especially when you use the "standard" pragma. </p> <p>It also allows you to put JavaScript and AJAXy stuff in the template itself which mimics the separation between client and server. </p> <p>These three modules are among the most popular on CPAN, have excellent documentation and a broad user base. Plus developing with these means you can rather quickly move to mod_perl once you have prototyped your code giving you a quick transition to Apache's embedded perl environment.</p> <p>All in all a compact yet flexible toolset.</p> |
