<p>I don't think your problem is the OR operator, but the <a href="http://www.regular-expressions.info/repeat.html#greedy">greediness</a> of the <code>.*</code>. It will match your full string, and then <em>back</em>-track until the following expressions match. The first match in this backtracking process will be <code>'He said, "You're cool."' , 'Rawr</code>+<code>')</code>. Try <code>.*?</code> instead!</p>

<p>Firstly, I agree with the previous answer that you should be using the strict equality operator. Secondly, you are using incorrect syntax - where you have data-bind should be ko, i.e.:</p> <pre><code>&lt;!-- ko if: header.current_collection.url_type === 'stories' --&gt; &lt;p&gt;text&lt;/p&gt; &lt;!-- /ko --&gt; </code></pre> <p>You can find the <a href="http://knockoutjs.com/documentation/if-binding.html" rel="nofollow noreferrer">knockout if binding docs here</a></p>

<p>A very "dirty" solution would be to systematically check that the function's local environment is not changed after the "preamble". </p> <pre><code>fun &lt;- function(x) { a &lt;- x ls1 &lt;- ls() if (a&lt;0) { if (a &gt; -50) x &lt;- -1 else x &lt;- -2 } ls2 &lt;- ls() print(list(c(ls1,"ls1"),ls2)) if (!setequal(c(ls1,"ls1"), ls2)) stop("Something went terribly wrong!") return(x) } fun.typo &lt;- function(x) { a &lt;- x ls1 &lt;- ls() if (a&lt;0) { if (a &gt; -50) x &lt;- -1 else X &lt;- -2 } ls2 &lt;- ls() print(list(c(ls1,"ls1"),ls2)) if (!setequal(c(ls1,"ls1"), ls2)) stop("Something went terribly wrong!") return(x) } </code></pre> <p>With this "solution", <code>fun.typo(-60)</code> no longer silently gives a wrong answer...</p>

Appcelerator ImageView, changing image on android blinks / flickers <p>I have 20 images which I cycle through to show a fitness exercise. When updating the image (i.e going from frame 1 to frame 2) the entire imageView blinks. This only happens on Android, on iOS it works fine. </p> <p>Here is a video of it happening <a href="https://youtu.be/-CufuQErQ58" rel="nofollow">https://youtu.be/-CufuQErQ58</a> This is on emulator but its also happening on all android devices i've tested on. </p> <p>I tried changing the imageView to just a view with a backgroundImage, and this works without blinking however it runs very slowly and uses a lot more memory and often crashes.</p> <pre><code>exports.imagesWindow = function(exercise, noOfImages) { var win = new SS.ui.win('landscape'); var imgCount = 0; var header = new SS.ui.view(win, '10%', '100%'); header.top = 0; header.visible = true; header.backgroundColor = SS.ui.colors[0]; var cueText = new SS.ui.normalLabel(header, "some text", 7); cueText.color = 'white'; //var imgLeft = new SS.ui.responsiveImage({container:win, top:'10%', left:'2%', height: '75%', width: '30%', zoom: 0.3}); //var imgCenter = new SS.ui.responsiveImage({container:win, top: '10%', left: '35%', height: '75%', width: '30%', zoom: 0.3}); //var imgRight = new SS.ui.responsiveImage({container:win, top:'10%', left: '68%', height:'75%', width:'30%', zoom: 0.3}); if (noOfImages === 3) { imgLeft = new ImagePanel(win, '17%'); imgCenter = new ImagePanel(win, '50%'); imgRight = new ImagePanel(win, '83%'); } else { imgLeft = new ImagePanel(win, '30%'); imgRight = new ImagePanel(win, '70%'); } function updateImages() { cueText.text = (eval(exercise + "Cues"))[imgCount]; instructionNumber.text = (imgCount+1) + "/20"; if (noOfImages === 3) { imgLeft.image = '/images/instructionImages/' + exercise + "/" + exercise + '_front_' + imgCount + '.jpg'; imgCenter.image = '/images/instructionImages/' + exercise + "/" + exercise + '_side_' + imgCount + '.jpg'; imgRight.image = '/images/instructionImages/' + exercise + "/" + exercise + '_back_' + imgCount + '.jpg'; //SS.log("image updated: " + imgLeft.image + " " + imgCenter.image + " " + imgRight.image); } else { imgLeft.image = '/images/instructionImages/' + exercise + "/" + exercise + '_front_' + imgCount + '.jpg'; imgRight.image = '/images/instructionImages/' + exercise + "/" + exercise + '_side_' + imgCount + '.jpg'; } } //view.add(win); var homeView = new SS.ui.view(win, '12%', '30%'); homeView.center = {x: '5%', y: '92%'}; homeView.visible = true; var home = new SS.ui.dateButton(homeView, 'footer/home'); home.addEventListener('click', function(){ if (start){ clearInterval(start); }; win.close(); }); var footerView = new SS.ui.view(win, '12%', '30%'); footerView.center = {x: '50%', y: '92%'}; footerView.visible = true; var prevImg = new SS.ui.dateButton(footerView, 'footer/prevFrame'); prevImg.left = 0; //prevImg.height = Ti.UI.SIZE;prevImg.width = Ti.UI.SIZE; prevImg.addEventListener('click', goToPrev); var nextImg = new SS.ui.dateButton(footerView, 'footer/nextFrame'); //nextImg.height = Ti.UI.SIZE; nextImg.width = Ti.UI.SIZE; nextImg.addEventListener('click', goToNext); nextImg.right = 0; var stopPlayBtn = new SS.ui.dateButton(footerView, 'footer/playVideo'); //stopPlayBtn.height = Ti.UI.SIZE;stopPlayBtn.width = Ti.UI.SIZE; stopPlayBtn.addEventListener('click', stopPlay); var numberView = new SS.ui.view(win, '12%', '30%'); numberView.center = {x: '95%', y: '92%'}; numberView.visible = true; var instructionNumber = new SS.ui.normalLabel(numberView, (imgCount+1) + "/20", 5); updateImages(); var start; function stopPlay() { // start videos if (stopPlayBtn.image.indexOf('play')&gt;=0) { cueText.visible = false; start = setInterval(goToNext, 200); stopPlayBtn.image = '/images/footer/stopVideo.png';} // stop vidoes else { clearInterval(start); cueText.visible = true; stopPlayBtn.image = '/images/footer/playVideo.png'; } } function goToPrev() { if (imgCount &gt; 0) { imgCount--; } else { imgCount = 19; }; SS.log("imgCount: " + imgCount); updateImages(); } function goToNext() { if (imgCount &lt; 19) { imgCount++; } else { imgCount = 0; }; SS.log("imgCount: " + imgCount); updateImages(); } return win; }; var ImagePanel = function(viewToAdd, cX) { var imageView = Ti.UI.createImageView({ width: '30%', borderColor: 'white', center: {x: cX, y: '50%'} }); viewToAdd.add(imageView); //resize for tablets if(Ti.Platform.osname.indexOf('ipad') &gt;=0) { imageView.height = '45%'; imageView.borderWidth = 8; imageView.borderRadius = 12; } else { imageView.height = '65%'; imageView.borderWidth = 4; imageView.borderRadius = 6; } return imageView; }; </code></pre> <p>EDIT</p> <p>So after a bit more digging I found this article - <a href="http://docs.appcelerator.com/platform/latest/#!/guide/Image_Best_Practices" rel="nofollow">http://docs.appcelerator.com/platform/latest/#!/guide/Image_Best_Practices</a></p> <p>It seems on android that the image size is the limiting factor, and reducing the size of the images helped fix this, although it still blinks on the first cycle of images.</p>

<p>There error is the two dimensional array in the <code>columns</code> function is not being set correctly. The variable name is missing and in the incorrect place for each column.</p> <p>Either you can set the columns like this:</p> <pre><code>public function columns() { return array( 'Title' =&gt; array( 'title'=&gt;_t('PageListByTypeReport.PageName', 'Page name') ), 'ClassName' =&gt; array( 'title'=&gt;_t('PageListByTypeReport.ClassName', 'Page type') ) ); } </code></pre> <p>Or even simpler like this:</p> <pre><code>public function columns() { return array( 'Title' =&gt; _t('PageListByTypeReport.PageName', 'Page name'), 'ClassName' =&gt; _t('PageListByTypeReport.ClassName', 'Page type') ); } </code></pre> <p>The current <code>sourceRecords</code> function will work, although we can make this much simpler by just returning the results of <code>Page::get()</code> like this:</p> <pre><code>public function sourceRecords($params = array(), $sort = null, $limit = null) { $pages = Page::get()-&gt;sort($sort); return $pages; } </code></pre> <p>Here is a working and simplified version of the Report code: </p> <pre class="lang-php prettyprint-override"><code>class PageListByType extends SS_Report { function title() { return 'Page List by Type'; } function description() { return 'List all the pages in the site, along with their page type'; } public function sourceRecords($params = array(), $sort = null, $limit = null) { $pages = Page::get()-&gt;sort($sort); return $pages; } public function columns() { return array( 'Title' =&gt; _t('PageListByTypeReport.PageName', 'Page name'), 'ClassName' =&gt; _t('PageListByTypeReport.ClassName', 'Page type') ); } } </code></pre>

how to covert PST to IST Using javascript <p>i get PST date formate from Database and i need to convert IST formate. But my system also in IST Formate. please check this <a href="http://jsfiddle.net/sfcdD/9/" rel="nofollow">http://jsfiddle.net/sfcdD/9/</a>. </p> <pre><code> var date = "2012-12-12 05:18:28.541"; // PST date formate fetch from db var offset = (3600000*(+5.30)); // IST gmtOffset value var dateformate = 'dd/mm/yyyy "at" h:MM TT'; var dateArray = (date).split(' '); var year = dateArray[0].split('-'); var time = dateArray[1].split(':'); var d = new Date($.trim(year[0]), $.trim(year[1]-1), $.trim(year[2]), $.trim(time[0]), $.trim(time[1])); utc = d.getTime() +(d.getTimezoneOffset()*60000); //d.getTimezoneOffset() is taking local timezone nd = new Date(utc + parseInt(offset)); alert(dateFormat(nd,dateformate)); // dispaly 12/12/2012 at 5:06 AM but need to display 12/12/2012 at 7:48 PM </code></pre> <p>so my conversion is not work. it display wrong date.</p>

Junit for spring security <p>I've used the spring security http element to enforce security, in the securityContext.xml. I am able to successful secure my web app. I want to write a junit for the same. Will I be able to write it.</p>

<p>Following lines of javascript worked for me.</p> <pre><code>Date utcDate; /*utcDate = your own initialisation statement here;*/ Date localDate = new Date(utcDate.getTime() + TimeZone.getDefault().getRawOffset()); </code></pre> <p>Alternatively you can try <a href="http://momentjs.com/" rel="nofollow noreferrer">moment.js</a> which won't add time offset automatically.</p> <p>Cheers!</p>

<p>This is because <code>image.Pointer()</code> is a smart pointer object, a wrapper around the read pointer to your data. You must pass <code>image.Pointer().GetPointer()</code> to fftw.</p>

onDraw() not being called <p>I am working on fixing someone's Android app. It was originally made for 2.1 and I am trying to get it work to 4.0+. Unfortunately the person who made the app is not around so I am stuck with his code.</p> <p>The app implements custom sliders, a horizontal and vertical. I got the vertical slider fixed, but I cannot get the horizontal slider to work. It is not calling <code>onDraw()</code>: When the view loads, <code>onDraw()</code> gets called and I see both of my sliders initialized, then when I move my horizontal slider it moves and calls <code>onDraw()</code> once, but never again will it call it, unlike the vertical slider which does call it.</p> <p>Here is the code:</p> <pre><code>public class PanSeekBar extends RelativeLayout { private RelativeLayout layout1;

How to publish Actions to Facebook Graph API with parameters in call URL <p>To begin, Ive spent several hours looking for an answer and have come CLOSE but havent found a full answer.</p> <p>So Im trying to publish actions using Facebook's Graph API and want to send parameters in the URL when initially calling it with the Facebook Javascript SDK.</p> <p>Here is a call that WORKS:</p> <pre><code> function postNewAction() { passString = '&amp;object=http://mysite.com/appnamespace/object.php'; FB.api('/me/APP_NAMESPACE:ACTION' + passString,'post', function(response) { if (!response || response.error) { alert(response.error.message); } else { alert('Post was successful! Action ID: ' + response.id); } } ); } </code></pre> <p>With object.php looking like so:</p> <pre><code> &lt;head xmlns:enemysearch="http://apps.facebook.com/APP_NAMESPACE/ns#"&gt; &lt;meta property="fb:app_id" content="APP_ID" /&gt; &lt;meta property="og:type" content="APP_NAMESPACE:object" /&gt; &lt;meta property="og:title" content="some title" /&gt; &lt;meta property="og:description" content="some description"/&gt; &lt;meta property="og:locale" content="en_US" /&gt; &lt;meta property="og:url" content="http://www.mysite.com/appnamespace/object.php"/&gt; &lt;/head&gt; </code></pre> <p>So obviously the above will post some sort of action to Facebook that will be the same every time object.php is called.</p> <p>This is not ideal for my purposes.</p> <p>So I took a look at <a href="http://stackoverflow.com/questions/8431694/dynamic-generation-of-facebook-open-graph-meta-tags">this thread</a> and it helped but as you will see, doesnt answer everything.</p> <p>So if I change object.php to include dynamically generated meta tags by using content from either GET or POST and use the <a href="http://developers.facebook.com/tools/debug" rel="nofollow">Object Debugger</a> with a matching URL format to the one provided in og:url, the debugger shows everything as working as I would expect with now warnings. Here is what the dynamically generated object.php looks like:</p> <pre><code> &lt;?php if(count($_GET) &gt; 0) { $userName = (int)$_GET['userName']; } else { $userName = (int)$_POST['userName']; } ?&gt; &lt;head xmlns:enemysearch="http://apps.facebook.com/APP_NAMESPACE/ns#"&gt; &lt;meta property="fb:app_id" content="APP_ID" /&gt; &lt;meta property="og:type" content="APP_NAMESPACE:object" /&gt; &lt;meta property="og:title" content=" &lt;?php echo $userName; ?&gt;" /&gt; &lt;meta property="og:description" content="Click to view more from &lt;?php echo $userName; ?&gt;"/&gt; &lt;meta property="og:locale" content="en_US" /&gt; &lt;meta property="og:url" content="http://mysite.com/appnamespace/object.php?userName=&lt;?php echo $userName; ?&gt;"/&gt; &lt;/head&gt; </code></pre> <p>SO, what I need to know is how to send url parameters in the initial call. If I use the debugger and enter something to the effect of <a href="http://mysite.com/appnamespace/object.php?userName=Brad" rel="nofollow">http://mysite.com/appnamespace/object.php?userName=Brad</a> everything works fine and the meta tags return content with that name inside of them. However if I try to pass the same url in the Javascript Call, it returns an error saying that my meta property og:type needs to be 'APP_NAMESPACE:object' (which as you see above, is what I have) instead of 'website' (which as you can see above, is something I am not using). Here is what that broken call would look like:</p> <pre><code> function postNewAction(userName) { passString = '&amp;object=http://mysite.com/appnamespace/object.php?userName=' + userName; FB.api('/me/APP_NAMESPACE:ACTION' + passString,'post', function(response) { if (!response || response.error) { alert(response.error.message); } else { alert('Post was successful! Action ID: ' + response.id); } } ); } </code></pre> <p>To be clear, the userName variable is only for example.</p> <p>Any thoughts?</p>

<blockquote> <p>However upon setting the static property, the original closure gets executed. It's not the case for lazy instance properties. Why is that?</p> </blockquote> <p>What answer would satisfy you? Are you asking for someone to read Apple's mind? You're as capable of reading the Swift source code as anyone else, so go read it and see what it does. Personally, I agree with your expectation. In my opinion this behavior is a bug, and I've filed a bug report with Apple. If you agree, file one too. But I wouldn't expect anything to change if I were you. And regardless, your question can appeal only to opinion, which is not a good fit for Stack Overflow.</p> <p>In case you're curious, my bug report is number 19085421, and reads, in part:</p> <blockquote> <p><strong>Summary:</strong> A lazy var's initializer should not be evaluated at all if the var is written to without being read first. But that is what a global var does.</p> <p><strong>Steps to Reproduce:</strong> Run the enclosed project.</p> <p><strong>Expected Results:</strong> I am assigning to the global var before anyone ever reads its value. Therefore I expect that its initializer will <em>never</em> be evaluated.</p> <p><strong>Actual Results:</strong> Its initializer <em>is</em> evaluated, as the logging in the console proves. This defeats, to some extent, the purpose of laziness.</p> </blockquote>

<p>I use <a href="https://github.com/mirek/CoreWebSocket" rel="nofollow">CoreWebSocket!</a>. It's pretty good so far. Best of all, i found it very easy to understand. It might be a good place to start.</p> <p>I also know of <a href="https://github.com/square/SocketRocket" rel="nofollow">SocketRocket</a>. Which I'm told is actually better. But I've been working with CoreWebSocket for a while now, and its working just fine to me. </p> <p>Both are pretty well documented. So I think these would be a good place to start. Let me know if you need anything else.</p> <p>Thats just the sockets though. I also have an 'always online' based application. Where the users are always online. The good thing is, sockets are persistent in the sense that you make the connection only once. For this you need some kind of turn server to figure out who's online and their credentials to connect. Once connected you can seamlessly send receive data between them with out involving an in-between server. </p> <p>If you need to be aware of what the users are sending and receiving, then its a good idea to have a server in-between, Where data is sent to the server first, and then forwarded to the appropriate users.</p> <p>The libraries above have some documentation on how they work, so you can use it to figure out some kind of architecture before you pick one of them to use.</p> <p>Good luck!</p> <p>EDIT: To be honest, sockets are meant for (in my opinion) live connections. So if you want to send and receive controls for a game or something of that sorts. The idea is that you don't need establish a new connection every time you want to send data. You make a connection once, and you can send and receive until it is closed. Is this the kind of application you're trying to make? </p>

<p>You can use javascript to submit the form.

How to find the kth smallest element within an interval of an array <p>Suppose I have an unsorted integer array a[] with length N. Now I want to find the kth smallest integer within a given interval a[i]-aj. Ex: I have an array a[10]={10,15,3,8,17,11,9,25,38,29}. Now I want to find the 3rd smallest element within [2,7] interval. The answer is 9. I know this can be done by sorting that interval. But this costs O(MlogM)(M=j-i+1) time. I also know that, this can be done by segment tree. But I can't understand how to modify it to handle such query.</p>

python cache dictionary - counting number of hits <p>I'm implementing a caching service in python. I'm using a simple dictionary so far. What I'd like to do is to count number of hits (number of times when a stored value was retrieved by the key). Python builtin dict has no such possibility (as far as I know). I searched through 'python dictionary count' and found <code>Counter</code> (also on stackoverflow), but this doesn't satisfy my requirements I guess. I don't need to count what already exists. I need to increment something that come from the outside. And I think that storing another dictionary with hits counting only is not the best data structure I can get :)</p> <p>Do you have any ideas how to do it efficiently?</p>

Golang: what's the point of interfaces when you have multiple inheritence <p>I'm a Java programmer, learning to program in Go. So far I really like the language.

You need to take into account performance though. If your xml files are large this won't perform as well I guess. If you only have small files the simplicity of this outweighs the small performance penalty. </p>

jquery form validation using groups <p>I have an order form, one part of the form is the address. It contains Company, Street-Address, ZIP, Town, Country with a simple jquery form validation with every field required, and ZIP validated for number. Now what I want is to group them and only have one field showing "valid address" on success, or "address wrong" on error.</p> <p>This is a part of my js code:</p> <pre><code>$("#pageform").validate( { messages: { company_from: addressError, //addressError is a JS var for the error message street_from: addressError, zip_from: addressError, town_from: addressError, country_from: addressError }, groups: { from: "company_from street_from zip_from town_from country_from" }, errorPlacement: function(error, element) { if (element.attr("name") == "company_from" || element.attr("name") == "street_from" || element.attr("name") == "zip_from" || element.attr("name") == "town_from" || element.attr("name") == "country_from" ) { $("#error_from").append(error); } }, success: function(label) { var attribute = $(label[0]).attr("for"); $(".err-ok-" + attribute + " .ok").css("display", "block").css("visibility", "visible"); } } ); </code></pre> <p>This is a part of the corresponding HTML code:</p> <pre><code>&lt;input type="text" name="company_from" id="company_from" class="required default input-s8" maxlength="255" /&gt; &lt;input type="text" name="street_from" id="street_from" class="required default input-s8" maxlength="255" /&gt; &lt;input type="text" name="zip_from" id="zip_from" class="required digits default input-s8" maxlength="5" onblur="checkCalculation()" /&gt; &lt;input type="text" name="town_from" id="town_from" class="required default input-s8" maxlength="255" /&gt; &lt;!-- and a select list for the country --&gt; </code></pre> <p>You do not need to take a closer look on how I show the error and so on, my problem is, that <strong>I do not know when to show the error label and when the success label</strong>. When I enter a letter for the ZIP code, my errorPlacement function and the success function is called (and the errorPlacement first), so I guess it's always calling the success if there is at least one field correct. </p> <p>Please ask if there are any questions, and I am pretty sure there are... :-)</p>

MySQL --> MongoDB: Keep IDs or create mapping? <p>We are going to migrate our database from MySQL to MongoDB. Some URLs pointing at our web application use database IDs (e.g. <a href="http://example.com/post/5" rel="nofollow">http://example.com/post/5</a>) At the moment I see two possibilities:</p> <p>1) Keep existing MySQL IDs and use them as MongoDB IDs. IDs of new documents will get new MongoDB ObjectIDs.</p> <p>2) Generate new MongoDB ObjectIDs for all documents and create a mapping with MySQLId --> MongoDBId for all external links with old IDs in it.</p> <p>2 will mess up my PHP app a little, but I could imagine that #1 will cause problems with indexes or sharding? What is the best practice here to avoid problems?</p>

<p>I found the quickest solution was to create a sql database with different tables for each type( Vehicles, Lookups etc.). When I just loaded all the data in and queried with a bunch of joins it took over a minute. But by creating foreign key references, indexes and adding primary keys to the table I got it down to less than a second. So I create the query from my c# Code and get back an object that contains all the information I need from each table.</p>

Wordpress Rest Api ionic app loading <p>I'm developing a Wordpress Ionic application using the Wordpress REST API and Jetpack. I followed a tutorial <a href="https://www.youtube.com/watch?v=jbopML8dnqg" rel="nofollow noreferrer">Hybrid Mobile Application with Ionic/Cordova</a>, but ran into an ugly problem. When I enter my REST API link in <code>$http.get()</code> and try it in my browser it keeps loading like this:</p> <p><a href="https://i.stack.imgur.com/tAY9L.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tAY9L.png" alt="http://imgur.com/gallery/6lqUK2M/"></a></p> <p>On the other hand, the <a href="http://But%20when%20I%20but%20freshly-press%20api%20it%20works" rel="nofollow noreferrer">Freshy-Pressed Api</a> works, though I don't know why.</p> <p>Here is the HTML and JavaScript I'm using:</p> <pre class="lang-js prettyprint-override"><code>var FPApp = angular.module("FPApp", ["ionic"]); FPApp.service("FPSvc", ["$http", "$rootScope", FPSvc]); FPApp.controller("FPCtrl", ["$scope", "$sce", "$ionicLoading", "$ionicListDelegate", "$ionicPlatform", "FPSvc", FPCtrl]); function FPCtrl($scope, $sce, $ionicLoading, $ionicListDelegate, $ionicPlatform, FPSvc) { $ionicLoading.show({template: "Loading blogs..."}); $scope.deviceReady = false; $ionicPlatform.ready(function() { $scope.$apply(function() { $scope.deviceReady = true; }); }); $scope.blogs = []; $scope.params = {}; $scope.$on("FPApp.blogs", function(_, result) { result.posts.forEach(function(b) { $scope.blogs.push({ name: b.author.name, avatar_URL: b.author.avatar_URL, title: $sce.trustAsHtml(b.title), URL: b.URL, featured_image: b.post_thumbnail.URL }); }); $scope.params.before = result.date_range.oldest; $scope.$broadcast("scroll.infiniteScrollComplete"); $scope.$broadcast("scroll.refreshComplete"); $ionicLoading.hide(); }); $scope.loadMore = function() { FPSvc.loadBlogs($scope.params); } $scope.reload = function() { $scope.blogs = []; $scope.params = {}; FPSvc.loadBlogs(); } $scope.show = function($index) { cordova.InAppBrowser.open($scope.blogs[$index].URL, "_blank", "location=no"); } $scope.share = function($index) { $ionicListDelegate.closeOptionButtons(); window.socialmessage.send({ url: $scope.blogs[$index].URL }); } } function FPSvc($http, $rootScope) { this.loadBlogs = function(params) { $http.get("https://public-api.wordpress.com/rest/v1/sites/100060382/posts/", { params: params}) .success(function(result) { $rootScope.$broadcast("FPApp.blogs", result); }); } } </code></pre> <pre class="lang-html prettyprint-override"><code>&lt;html lang="en" data-ng-app="FPApp"&gt; &lt;head&gt; &lt;meta charset="UTF-8"&gt; &lt;title&gt;Document&lt;/title&gt; &lt;!--Setup Cordova--&gt; &lt;meta http-equiv="Content-Security-Policy" content="default-src *;"&gt; &lt;script src="cordova.js"&gt;&lt;/script&gt; &lt;!--Setup Ionic--&gt; &lt;link rel="stylesheet" href="lib/ionic/css/ionic.css"&gt; &lt;script src="lib/ionic/js/ionic.bundle.js"&gt;&lt;/script&gt; &lt;!--Setup Application--&gt; &lt;link rel="stylesheet" href="index.css"&gt; &lt;script src="index.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body data-ng-controller="FPCtrl"&gt; &lt;ion-pane&gt; &lt;div class="bar bar-header bar-energized"&gt; &lt;h1 class="title"&gt;ZahranPress&lt;/h1&gt; &lt;/div&gt; &lt;ion-content class="background"&gt; &lt;ion-refresher pulling-text="Pull" on-refresh="reload()"&gt; &lt;/ion-refresher&gt; &lt;div class="list card" data-ng-repeat="b in blogs"&gt; &lt;div class="item item-avatar"&gt; &lt;img data-ng-src="{{b.avatar_URL}}" alt=""&gt; &lt;h2 data-ng-bind-html="b.title"&gt;&lt;/h2&gt; &lt;p&gt; {{ b.name }} &lt;/p&gt; &lt;/div&gt; &lt;div class="item item-body"&gt; &lt;img data-ng-if="b.featured_image" data-ng-src="{{ b.featured_image }}" alt="" class="full-image"&gt; &lt;/div&gt; &lt;div class="item tabs tabs-secondary tabs-icon-left"&gt; &lt;a class="tab-item" data-ng-click="show($index)"&gt; &lt;i class="icon ion-ios-book"&gt;&lt;/i&gt; Read &lt;/a&gt; &lt;a class="tab-item" data-ng-click="share($index)"&gt; &lt;i class="icon ion-share"&gt;&lt;/i&gt; Share &lt;/a&gt; &lt;/div&gt; &lt;/div&gt; &lt;ion-infinite-scroll on-infinite="loadMore()" ng-if="deviceReady"&gt;&lt;/ion-infinite-scroll&gt; &lt;/ion-content&gt; &lt;/ion-pane&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>How do I resolve this problem?</p>

<p>You could do something like this:</p> <pre><code>select ID, max(case when CVG = 'A' then 'TRUE' else 'FALSE' end), max(case when CVG = 'B' then 'TRUE' else 'FALSE' end), max(case when CVG = 'C' then 'TRUE' else 'FALSE' end), from table group by ID </code></pre> <p>The case + max will select the true if even one row is found for that ID, otherwise false.</p>

Using IF EXISTS with a CTE <p>I want to check if a CTE table has record or null. But I always get error message 'Incorrect syntax near the keyword 'IF'' for the SQL below. Now there is no matching record in ADMISSION_OUTSIDE TABLE. The result of the SQl should print 'NOT OK'. Thanks,</p> <pre><code>WITH ADMISSION_OUTSIDE AS ( ..... ..... ) IF EXISTS (SELECT * FROM ADMISSION_OUTSIDE) PRINT 'OK' ELSE PRINT 'NOT OK' </code></pre>

<p>Make the first function call the next one and add this to your HTML :</p> <pre><code> &lt;input&gt; type=button onclick="validateForm(); return false;" &lt;/input&gt; </code></pre> <p>Putting 'return false' will prevent redirection and will give time for your function to execute.</p> <pre><code>function validateForm(){ var email = document.forms["form"]["Email"].value; if(email == null || email == ""){ alert("Email must be filled out"); return false; } else redirect(); } </code></pre> <p>Additionally, I'd recommend to abstain from putting any code in your HTML. It is considered a "bad practice". However, if you still want to put your code, it'll be more appropriate to put it in the form as an "onsubmit" action:</p> <pre><code>&lt;form onsubmit="validateForm()"&gt; </code></pre> <p>If you want the function to execute when the submit button is clicked, you can just add an event listener in your script and an id to your button, like this:</p> <pre><code>var button = document.getElementById("submit"); button.onclick = function validateForm() { /*same code as above..*/ }; </code></pre> <p>Hope it helps!</p>

Advice about INSERT statement performance in SQL Server <p>I need to generate random numbers in SQL Server and write these codes into the table. I used the SQL statement as follows:</p> <pre><code>while (select count(code) from tb_random) &lt;1000000 begin SET NOCOUNT ON declare @r int set @r = rand()*10000000 insert into tb_random values(@r) end </code></pre> <p>It takes over 20h to complete this query. Could you give me an idea to solve this performance problem?</p>

<p>An alternative solution might be to create a database view on table1, with a field called something like <code>title_Name</code> (defined as table1.Name for version #1, and as table1.title for version #2), and use the database view instead of table1 in your query, joined like so:</p> <pre><code>INNER JOIN table3 t3 on t1.title_Name = t3.Name </code></pre>

Figuring out an offset in assembly with OllyDBG <p>Relevant assembly:</p> <pre><code>$ &gt; 94D3A705 PUSH hw.05A7D394 ; ASCII "glBegin" $+5 &gt; E8 99C80500 CALL &lt;JMP.&amp;SDL2.SDL_GL_GetProcAddress&gt; $+A &gt; 83C4 04 ADD ESP,4 $+D &gt; A3 04E03B06 MOV DWORD PTR DS:[63BE004],EAX $+12 &gt; 8B0D 04E03B06 MOV ECX,DWORD PTR DS:[63BE004] ; OPENGL32.glBegin $+18 &gt; 890D 38E83B06 MOV DWORD PTR DS:[63BE838],ECX </code></pre> <p>The first line pushes a string address onto stack as function argument. And the last line copy's value from ECX to this DWORD data object. This address is my target. I want to replace the containing DWORD value.</p> <p>In my C++ code I first obtain the address for the first line's push function and then I add an offset. By adding the offset 0x1A the code works, but when I try adding + 0x18 then it doesn't work.</p> <p>I don't fancy testing this for every function, what is the underlying idea that I'm missing?</p>

Show progress while running python unittest? <p>I have a very large TestSuite that I run with <code>TextTestRunner</code> from the python unittest framework. Unfortunately I have no idea how many tests are already done while the test are running.</p> <p>Basically I'd like to convert this output:</p> <pre><code>test_choice (__main__.TestSequenceFunctions) ... ok test_sample (__main__.TestSequenceFunctions) ... ok test_shuffle (__main__.TestSequenceFunctions) ... ok ---------------------------------------------------------------------- Ran 3 tests in 0.110s OK </code></pre> <p>to</p> <pre><code>[1/3] test_choice (__main__.TestSequenceFunctions) ... ok [2/3] test_sample (__main__.TestSequenceFunctions) ... ok [3/3] test_shuffle (__main__.TestSequenceFunctions) ... ok ---------------------------------------------------------------------- Ran 3 tests in 0.110s OK </code></pre> <p>Do I have to subclass <code>TextTestRunner</code> to achieve this and if yes, how?</p> <p><em>Note: I'm aware of nose and the available plugins, but it does not quite fit in my application and I'd like to avoid the dependency.</em></p> <p><strong>EDIT</strong> Why I'd like to avoid <em>nose</em>:</p> <p>My Application is basically an additional framework for the tests. It select the correct test cases, provides library functions for them and executes the tests multiple times for long term testing. (the tests run against an external machine)</p> <p>So here is how I run my tests right now:</p> <pre><code># do all sort of preperations [...] test_suite = TestSuite() repeatitions = 100 tests = get_tests() for i in range(0, repeatitions): test_suite.addTests(tests) TextTestRunner(verbosity=2).run(test_suite) </code></pre> <p>My problem with nose is, that it is designed to discover the tests from the filesystem and I was unable to find a clear documentation how to run it on a particular TestSuite directly from python.</p>

Creating library project and integrating into existing project in android <p>I have an application that has got two basic screens, a home page and a sliding drawer menu fragment to the left of home page like the facebook sliding drawer. Now I am planning to create another page to the right of the home page that appears by sliding to the other side. i would like to create this as a library project and just import it to the existing project. how can I do this. I need to display the the new menu drawer on sliding after adding the library project. How can I achieve this ? That is, I will be having a fragment in the library project that populates data by all necessary api calls from server, and I need to inflate the fragment by sliding in the main project.</p>

How to build cross-IDE java GUI's using "interface builders"? <p>In a Java project with developers that use different IDEs, say Eclipse and IntelliJ, what's the best way of developing visual components using the tools offered by the IDEs ("<a href="http://eclipse.org/vep/" rel="nofollow noreferrer">Visual Editor Project</a>" for Eclipse and "<a href="http://www.jetbrains.com/idea/features/gui_builder.html" rel="nofollow noreferrer">Swing GUI Designer</a>" for IntelliJ)?</p> <p>If a developer using Eclipse needs to make changes to a GUI written by another developer in IntelliJ (and vice versa) he will have quite a hard time and maybe even make the code incompatible with the original tool that built it.</p> <p>Is there a solution or do all developer just need to use the same tool?</p>

<p>Your only option in JSON for a null value is <code>null</code>. <code>""</code> isn't null, it's an empty string. <code>{}</code> is an empty object. <code>[]</code> is an empty array. I would use those where it was appropriate to have empty strings, objects, or arrays, but for null I'd use <code>null</code>.</p> <p>I don't like just leaving the property off entirely (which is what I think you mean by #3), because I prefer that the JSON structure be clear even when a value is omitted. But that's a subjective response, and people can have different opinions about it.</p>

PHP Related items from database <p>I have been googling for a while and searching SO but I still can't find an answer.</p> <p>So my problem is that I want to pull related content from mySQL database on what id is currently being displayed on the page. In the database I have a column dedicated to keywords, and I am using the LIKE query to pull id's based on those keywords. However, I get only one id because the LIKE query looks at the keyword literally. For example, keyword1 = 'apples berries oranges' is not the same as keywords2 = 'apples' 'berries' 'oranges'. I want the latter so it can pull in more related data.</p> <p>I also think I may be approaching this wrong, but I don't know any other way to pull related items.</p> <p>Here's my code...</p> <pre><code>&lt;?php include 'data/data_connect.php'; if ($sugg_qs = $db-&gt;query("SELECT * FROM questions WHERE keywords LIKE '$keywords' LIMIT 4")) { if ($q_count = $sugg_qs-&gt;num_rows) { echo $q_count; while($row = $sugg_qs-&gt;fetch_assoc()) { echo $row-&gt;title; } $sugg_qs-&gt;free(); } else { die('error'); } } else { die('error'); } ?&gt; </code></pre> <hr> <p>UPDATE</p> <pre><code>if ($sugg_qs = $db-&gt;query("SELECT * FROM questions WHERE keywords LIKE CONCAT('%', '$keywords' ,'%') LIMIT 3")) { if ($q_count = $sugg_qs-&gt;num_rows) { $row = $sugg_qs-&gt;fetch_all(MYSQLI_ASSOC); foreach ($row as $rows) { echo $rows['title']; } } else { die('error'); } </code></pre> <p>This code does work with id's that only have one keyword. So I guess a possible (but undesired) solution would be to create a new column for each new keyword and use LIKE for each keyword.</p> <p>Is there a way to avoid creating more columns?</p> <p>THANKS for those who helped already :)</p> <hr> <p>FINAL UPDATE? Ok. So I figured it out in probably the messiest way to write code, but apparently it works for me. So first of all I standardized my table where each element is limited to only 5 keywords and 1 category. So in the query I call for items with similar keywords, and if there aren't similar results I then call for items from the same category from the original item. </p> <p>Here is the (messy) code for those looking for a solution!</p> <pre><code>$q_kw_arr = explode(' ', $keywords); if ($sugg_qs = $db-&gt;query("SELECT keywords, category, title FROM questions WHERE keywords LIKE CONCAT('%', '$q_kw_arr[0]' ,'%') OR CONCAT('%', '$q_kw_arr[1]' ,'%') OR CONCAT('%', '$q_kw_arr[2]' ,'%') OR CONCAT('%', '$q_kw_arr[3]' ,'%') OR CONCAT('%', '$q_kw_arr[4]' ,'%') OR category= '$category' LIMIT 4")) { if ($q_count = $sugg_qs-&gt;num_rows) { $row = $sugg_qs-&gt;fetch_all(MYSQLI_ASSOC); foreach ($row as $rows) { echo $rows['title']; } } else { echo 'error'; } } </code></pre> <p>SPECIAL THANKS TO..</p> <p>Terminus, Grzegorz J, and infidelsawyer</p>

A kernel module to transparently detour packets coming from a NIC and TCP application. Is it possible to make it done? <p>Is it possible for a Linux kernel module to transparently detour the packet coming from upper layer (i.e. L2,L3) and NIC? For example, <strong>1)</strong> a packet arrives from a NIC, the module gets the packet (do some processing on it) and delivers back to tcp/ip stack or <strong>2)</strong> an app sends data, the module gets the packet (do some processing) and then, delivers the packet to an output NIC.</p> <p>It is not like a sniffer, in which a copy of the packet is captured while the actual packet flow continues. </p> <p>I thought on some possibilities to achieve my goal. I thought in registering a <strong>rx_handler</strong> in the kernel to get access to the incoming packets (coming from a NIC), but how to delivers back to the kernel stack? I mean, to allow the packet to follow the path that it should have taken without the module in the middle.</p> <p>Moreover, let's say an app is sending a packet through TCP protocol. How the module could detour the packet (to literally get the packet)? Is it possible? In order to send it out through the NIC, I think <strong>dev_queue_xmit()</strong> does the job, but I'm not sure.</p> <p>Does anyone know a possible solution? or any tips? </p> <p>Basically, I'd like to know if there is a possibility to put a kernel module between the NIC and the MAC layer.. or in the MAC layer to do what I want. In positive case, does anyone has any hint like main kernel functions to use for those purposes?</p> <p>Thanks in advance. </p>

How to create a strict 4-digit PIN input in plain JavaScript? <p>I'm trying to create a PIN input, wherein the user may only use 4 digits.</p> <p>In my code, I have managed to exclude A-Z and any other keys like curly braces, colons and so on, but I have faced some trouble with excluding the special characters (shift + 0-9).</p> <p>Regarding the length, I have successfully set it to 4, but if 4 is reached and one wants to delete it doesn't go past 3.</p> <p>My code:</p> <pre><code>var pin = document.forms.RegForm.pin; pin.onkeydown = function(key) { var allowedkeys = [], auxkeys = [8, 13, 17, 18, 46], specChars = "!@#$%^&amp;*()", keypressed = String.fromCharCode(key.which); allowedkeys.push(auxkeys); for (var i = 37; i &lt; 41; i++) allowedkeys.push(i); for (var i = 48; i &lt; 58; i++) allowedkeys.push(i); for (var i = 96; i &lt; 106; i++) allowedkeys.push(i); if (this.value.length &lt;= 3) { if (specChars.indexOf(keypressed) !== -1 || (key.which &lt; 48 || key.which &gt; 57) &amp;&amp; (key.which &lt; 96 || key.which &gt; 105)) key.preventDefault(); } else { if (auxkeys.indexOf(key.which) === -1) return false; } }; </code></pre> <p>I know the length can easily be done with maxlength = "4" in HTML, but for the purpose of getting to know JavaScript better, I would prefer an 'in JavaScript' solution.</p> <p>Should you provide an answer or a link to a similar question, if there is one, I would appreciate it.

<p><code>void checkCollisions();</code> (in <code>moveBalls</code>) is a function prototype, not a function call. Remove the <code>void</code>.</p>

<p>The best way to do this is to use something like <a href="http://nuget.org/packages/MoreLinq.Source.MoreEnumerable.Batch/" rel="nofollow">the <code>Batch</code> method from <code>MoreLinq</code></a>.</p> <p>This lets you partition the items in a sequence into batches of a specified size.</p> <p>If you want a simple approach which doesn't need to be threadsafe (i.e. you don't need to use it with <code>Parallel.ForEach()</code> for example) then you can use the following extension method.</p> <p>It has the advantage that you can produce all the batches without calling Skip multiple times:</p> <pre><code>public sealed class Batch&lt;T&gt; { public readonly int Index; public readonly IEnumerable&lt;T&gt; Items; public Batch(int index, IEnumerable&lt;T&gt; items) { Index = index; Items = items; } } public static class EnumerableExt { // Note: Not threadsafe, so not suitable for use with Parallel.Foreach() or IEnumerable.AsParallel() public static IEnumerable&lt;Batch&lt;T&gt;&gt; Partition&lt;T&gt;(this IEnumerable&lt;T&gt; input, int batchSize) { var enumerator = input.GetEnumerator(); int index = 0; while (enumerator.MoveNext()) yield return new Batch&lt;T&gt;(index++, nextBatch(enumerator, batchSize)); } private static IEnumerable&lt;T&gt; nextBatch&lt;T&gt;(IEnumerator&lt;T&gt; enumerator, int blockSize) { do { yield return enumerator.Current; } while (--blockSize &gt; 0 &amp;&amp; enumerator.MoveNext()); } } </code></pre> <p>And you use it like:</p> <pre><code> var items = Enumerable.Range(100, 510); // Pretend we have 50 items. int itemsPerPage = 20; foreach (var page in items.Partition(itemsPerPage)) { Console.Write("Page " + page.Index + " items: "); foreach (var i in page.Items) Console.Write(i + " "); Console.WriteLine(); } </code></pre> <p>But if you need threadsafe partitioning, use the MoreLinq Batch method I linked above.</p>

<p>Instead of increasing the indentation level with each request, you can return the request to the original promise chain and add a <code>then</code> there. Like this:</p> <pre><code>fetchUserById = function(id) { var user = {}; return knex_instance('user_info').where('id', id).first() .then(function(data) { if (!data) return null; user.info = data; return knex_instance('user_table').where('id', id).first(); }) .then(function(values) { if (!values) return null; user.values = values; return user; }); .catch(errorHandler('fetchUserById', id)); } </code></pre> <p>Problem with this approach, the <code>null</code> that can be returned by the first <code>then</code> must be passed through the second one (and the third, fourth, etc, if you had some). An alternate method would have been to use exceptions instead of returning null:</p> <pre><code>fetchUserById = function(id) { var user = {}; return knex_instance('user_info').where('id', id).first() .then(function(data) { if (!data) throw "NO_USER_INFO"; user.info = data; return knex_instance('user_table').where('id', id).first(); }) .then(function(values) { user.values = values; return user; }); .catch(function(err) { if (err==="NO_USER_INFO") return null; else return errorHandler('fetchUserById', id); } } </code></pre>
