9,704,131 | 0 | <p>You can make new union case values based on existing value of the same union case using Reflection. In order to achieve this just add instance member <code>Same</code> to your discriminated union, which first derives specific union case from the instance <code>self</code> and then constructs a new instance by the same union case, but now populated with <code>newVal</code>:</p> <pre><code>open Microsoft.FSharp.Reflection type Currency = | Dollar of int | Euro of int member self.Same newVal : Currency = FSharpValue.MakeUnion(fst (FSharpValue.GetUnionFields(self, typeof<Currency>)), [|newVal|]) |> unbox </code></pre> <p>Now applying it to <code>lowPrice</code> value below</p> <pre><code>let lowPrice = Euro(100) let highPrice = lowPrice.Same 200 </code></pre> <p>you'll get <code>highPrice : Currency = Euro 200</code></p> |
31,280,140 | 0 | <p>As @CBroe points out, this isn't supported by the Facebook Graph API. (It can be done using <a href="https://developers.facebook.com/docs/reference/fql/" rel="nofollow">FQL</a>, but that's deprecated and won't be supported for much longer).</p> <p>That said, with some creativity (and a bit extra code) a similar effect can be achieved by combining a couple of queries. </p> <p>In my application, I perform a query with the following parameters:</p> <ul> <li><code>until=2015-07-07</code> (or whatever the <code>since</code> date would have been)</li> <li><code>fields=updated_time</code> (to keep the query fast and the payload small)</li> <li><code>limit=5000</code> (or some similarly large page size, as I'm only grabbing one field)</li> </ul> <p>I then evaluate each post that has an <code>updated_time</code> greater than the would-be <code>since</code> date, and throw those posts into a queue to download the entirety of the post content. </p> <blockquote> <p><em>Note:</em> If you're dealing with content where there are frequent updates on past content, you'd likely want to use the Graph API's <a href="https://developers.facebook.com/docs/graph-api/making-multiple-requests" rel="nofollow">Batch Requests feature</a>, as opposed to downloading each post individually.</p> </blockquote> <p>So, for example, if the <code>until</code> (and, thus, <code>since</code>) date is <code>2015-07-07</code> and the <code>updated_time</code> on a post is <code>2015-10-15</code>, then I know that post was created prior to <code>2015-07-07</code> but updated afterwards. It won't get picked up in a <code>since</code> query, but I can easily download it individually to synchronize my cache.</p> |

9,910,853 | 0 | <p>Android reserves the right to kill any application or component that isn't visible to the user (even those can be killed, but it's a rare occurrence). Most often, this is due to memory pressure, and the system kills applications to free up resources.</p> <p>If you have a long-running process that runs in the background and it should run continuously, your best bet is to make it a <a href="http://developer.android.com/reference/android/app/Service.html#startForeground%28int,%20android.app.Notification%29" rel="nofollow">foreground service</a>. This will put the service at a higher priority than a background service, and should be interrupted less by the system.</p> <p>However, unless your service NEEDS to run in the foreground, you should implement your service to gracefully handle being torn down and built up by the system, since it usually kills the service for a good reason. Forcing your service into the foreground might increase the risk of hurting overall device performance, and it does force the presence of a persistent notification in the notification bar, which annoys some users (at least me).</p> |

8,593,533 | 0 | <p>This is a fairly common problem.</p> <p>One often used solution is to have pipes as a communication mechanism from worker threads back to the I/O thread. Having completed its task a worker thread writes the pointer to the result into the pipe. The I/O thread waits on the read end of the pipe along with other sockets and file descriptors and once the pipe is ready for read it wakes up, retrieves the pointer to the result and proceeds with pushing the result into the client connection in non-blocking mode.</p> <p>Note, that since pipe reads and writes of less then or equal to <code>PIPE_BUF</code> are atomic, the pointers get written and read in one shot. One can even have multiple worker threads writing pointers into the same pipe because of the atomicity guarantee.</p> |

30,010,264 | 0 | <p>I'm just messing around with the Gdriv.es service and the link you posted. Thanks for sending me down the rabbit-hole... </p> <p>Google Drive folders seem to either have 28 or 72 character long ids. Most of your product subfolders have the 28 character id format. Interestingly, there are some other folders that show up in your posted link that don't if you go in a different way to the same folder <a href="https://drive.google.com/drive/folders/0ByX-7AGzNtLkfnJDcC0tRm5xcE9aYlp3akljS3p4OWxpeDNId0FlaEdONFVTak0xeld4NGc" rel="nofollow">https://drive.google.com/drive/folders/0ByX-7AGzNtLkfnJDcC0tRm5xcE9aYlp3akljS3p4OWxpeDNId0FlaEdONFVTak0xeld4NGc</a></p> <p>Going through my own drive, what I'm seeing is that all of the older folders I have from 2009 and earlier have the 72 character id format. Folders from 2012 are 28 character ids. Unfortunately, I don't have anything in mine between summer 2009 and 2012.</p> <p>A quick twitter search shows a <a href="https://twitter.com/vivekhaldar/status/275090459867635713" rel="nofollow">Dec 2012 tweet</a> that kind of looks like an announcement.</p> <p>My guess is there was some sort of API change with Google Drive from the 72 to the 28 character ids before then, and Gdriv.es doesn't support the old format. Maybe if your root folder was created before that change, you could create a new root folder and shift your content over?</p> |

The IBAction can create an instance of the New Person VC.</p> <p>If you need to predefine some of the fields for the new contact, you will need to create an ABRecordRef and set the properties you want to be in the new contact.

20,534,760 | 0 | <p>You can use Householder elimination to get the QR decomposition of <code>delta0</code>. Then the determinant of the Q part is +/-1 (depending on whether you did an even or odd number of reflections) and the determinant of the R part is the product of the diagonal elements.

4,402,288 | 0 | <p>I'm not an expert in hard real-time scheduling, but this is what your algorithm sounds like to me.</p> <p>It bears very strong resemblance with what happens in aerospace systems. Your system looks more flexible, but basically it all grinds down to knowing in advance that you have the resources to run the tasks that you need to run.</p> <p>Critical embedded aerospace systems prefer to be deterministic, but as a protection against potential flaws (tasks can run longer than allocated, if let), the tasking engine will interrupt those tasks to let other taks complete. Any free cycle left can sometimes be used to complete the interrupted tasks, or the task is deemed to have failed.</p> <p>Note that you can only fail tasks that are not critical, so you must construct your critical tasks carefully, or have a priority system whereby critical tasks have a chance to complete no matter what.</p> <p>You're now back to square one: you need to make sure that the ressources are sufficient to run the tasks required in advance.</p> <p>hth,<br> asoundmove.</p> |

23,207,215 | 0 | Free scrolling and parallax issue (jQuery Scroll Path + Parallax) <p>in a project where I need to build something like the famous parallax-powered Mario Kart Wii Experience site, which also comes with horizontal and vertical scroll (if you haven't seen it, here it is: <a href="http://www.nintendo.com.au/gamesites/mariokartwii/#home" rel="nofollow">http://www.nintendo.com.au/gamesites/mariokartwii/#home</a>)</p> <p>For the scrolling effect, I grabbed the JQuery Scroll Path plugin (website here: <a href="http://joelb.me/scrollpath/" rel="nofollow">http://joelb.me/scrollpath/</a>), and it seems to suit my needs concerning the free scrolling. </p> <p>The problem comes when I try to include some plugin to generate the parallax effect. I tried several plugins (including Stellar.js, jInvertScroll, Parallax.js, Parallax-JS), but none of them seem to work properly. I assume that there's some kind of relationship between the custom scroll that comes with the Scroll Path plugin and the need of the parallax plugins of working with the navigator scroll to make the effect work.</p> <p>I searched in Google for some similar situation (i.e., implementing Scroll Path with some parallax plugin) but I didn't find anyone in my current situation, and it seems that the Scroll Path plugin isn't maintained anymore.</p> <p>Any idea for making it work would be appreciated!</p> <p>PS: Sorry for the grammar mistakes, I'm still in process of learning english.</p> |

36,665,346 | 0 | <p>Two notes: such more complex query conditions cannot be written using symbols, you have to use string notation instead. And, secondly, a scope does not need to have a parameter, your <code>latest</code> scope is one of them, as you simply compare the <em>database</em> <code>created_at</code> time with the current time shifted by 5 days. So, the correct scope should be something like:</p> <pre><code>scope :latest, -> { where("created_at >= ?", Time.now - 5.days) } </code></pre> <p>and you call it simply:</p> <pre><code>@workers = Worker.company_id(@company.id).latest </code></pre> |

21,677,171 | 0 | <p>If you're using 11g or later version of Oracle, the easiest way to transpose rows into columns is PIVOT operator (<a href="http://www.oracle-base.com/articles/11g/pivot-and-unpivot-operators-11gr1.php" rel="nofollow">documentation</a>). For example, consider this query - it'll give you the table of all roles and privileges with corresponding values for them:</p> <pre><code>SELECT * FROM (SELECT fj.role_name, fj.priv_name, DECODE(rp.val,1,'YES',0,'NO','-') VAL FROM (SELECT r.id role_id, r.name role_name, p.id priv_id, p.name priv_name FROM ROLE r, PRIVILEGE p) fj LEFT JOIN ROLE_PRIV rp ON fj.role_id = rp.role_id AND fj.priv_id = rp.priv_id) PIVOT (MAX(VAL) FOR PRIV_NAME IN (list_of_privileges)) ORDER BY ROLE_NAME </code></pre> <p>But there is a catch with such solution: you need to name each privilige in IN clause (or use XML keyword, but it'll mess up the result), but, considering that list of priviliges supposed to change not so frequently, it shouldn't be a problem. The following example:</p> <pre><code>WITH ROLE AS (SELECT 1 ID, 'ROLE1' NAME FROM DUAL UNION SELECT 2 ID, 'ROLE2' NAME FROM DUAL UNION SELECT 3 ID, 'ROLE3' NAME FROM DUAL), PRIVILEGE AS (SELECT 1 ID, 'READ' NAME FROM DUAL UNION SELECT 2 ID, 'WRITE' NAME FROM DUAL UNION SELECT 3 ID, 'EXECUTE' NAME FROM DUAL), ROLE_PRIV AS (SELECT 1 ROLE_ID, 1 PRIV_ID, 1 VAL FROM DUAL UNION SELECT 1 ROLE_ID, 2 PRIV_ID, 0 VAL FROM DUAL UNION SELECT 2 ROLE_ID, 1 PRIV_ID, 1 VAL FROM DUAL UNION SELECT 2 ROLE_ID, 2 PRIV_ID, 0 VAL FROM DUAL UNION SELECT 3 ROLE_ID, 1 PRIV_ID, 0 VAL FROM DUAL UNION SELECT 3 ROLE_ID, 3 PRIV_ID, 1 VAL FROM DUAL) SELECT * FROM (SELECT fj.role_name, fj.priv_name, DECODE(rp.val,1,'YES',0,'NO','-') VAL FROM (SELECT r.id role_id, r.name role_name, p.id priv_id, p.name priv_name FROM ROLE r, PRIVILEGE p) fj LEFT JOIN ROLE_PRIV rp ON fj.role_id = rp.role_id AND fj.priv_id = rp.priv_id) PIVOT (MAX(VAL) FOR PRIV_NAME IN ('READ','WRITE','EXECUTE')) ORDER BY ROLE_NAME </code></pre> <p>Will give you the following result:</p> <pre><code>ROLE_NAME 'READ' 'WRITE' 'EXECUTE' ROLE1 YES NO - ROLE2 YES NO - ROLE3 NO - YES </code></pre> <p>If you're using the earlier version of Oracle, you can consider alternative solutions (<a href="http://asktom.oracle.com/pls/apex/f?p=100:11:0%3a%3a%3a%3aP11_QUESTION_ID:31263576751669#76663048528720" rel="nofollow">like this one</a>).</p> <hr> <p>Well, if you can't use PIVOT operation, the simplest way to get the desired output would be this query:</p> <pre><code>SELECT p.name, DECODE((SELECT VAL FROM ROLE_PRIV rp WHERE rp.role_id = (SELECT ID FROM ROLE r WHERE r.name = :ROLE_NAME) AND rp.priv_id = p.id), 1, 'YES', 0, 'NO', '-') :ROLE_NAME FROM PRIVILEGE p </code></pre> <p>You can add addtional roles to this query by just adding another column. For example, take a look at this query:</p> <pre><code>WITH ROLE AS (SELECT 1 ID, 'ROLE1' NAME FROM DUAL UNION SELECT 2 ID, 'ROLE2' NAME FROM DUAL UNION SELECT 3 ID, 'ROLE3' NAME FROM DUAL), PRIVILEGE AS (SELECT 1 ID, 'READ' NAME FROM DUAL UNION SELECT 2 ID, 'WRITE' NAME FROM DUAL UNION SELECT 3 ID, 'EXECUTE' NAME FROM DUAL), ROLE_PRIV AS (SELECT 1 ROLE_ID, 1 PRIV_ID, 1 VAL FROM DUAL UNION SELECT 1 ROLE_ID, 2 PRIV_ID, 0 VAL FROM DUAL UNION SELECT 2 ROLE_ID, 1 PRIV_ID, 1 VAL FROM DUAL UNION SELECT 2 ROLE_ID, 2 PRIV_ID, 1 VAL FROM DUAL UNION SELECT 3 ROLE_ID, 1 PRIV_ID, 0 VAL FROM DUAL UNION SELECT 3 ROLE_ID, 3 PRIV_ID, 1 VAL FROM DUAL) SELECT p.name, DECODE((SELECT VAL FROM ROLE_PRIV rp WHERE rp.role_id = (SELECT ID FROM ROLE r WHERE r.name = 'ROLE1') AND rp.priv_id = p.id), 1, 'YES', 0, 'NO', '-') ROLE1, DECODE((SELECT VAL FROM ROLE_PRIV rp WHERE rp.role_id = (SELECT ID FROM ROLE r WHERE r.name = 'ROLE2') AND rp.priv_id = p.id), 1, 'YES', 0, 'NO', '-') ROLE2, DECODE((SELECT VAL FROM ROLE_PRIV rp WHERE rp.role_id = (SELECT ID FROM ROLE r WHERE r.name = 'ROLE3') AND rp.priv_id = p.id), 1, 'YES', 0, 'NO', '-') ROLE3 FROM PRIVILEGE p </code></pre> <p>It will provide you result for three roles.</p> <hr> <p>Something like this should work:</p> <pre><code>SELECT p.name, DECODE((SELECT COUNT(1) FROM ROLE_PRIV rp WHERE rp.role_id = (SELECT ID FROM ROLE r WHERE r.name = 'ROLE1') AND rp.priv_id = p.id), 0, 'NO', 'YES') ROLE1 FROM PRIVILEGE p </code></pre> |

I managed to show the <code>$categoryName</code> and the <code>$SubCategoryName</code> with this function:</p> <pre><code>function showMenuCategory(){ $db = db_connect(); $query = "SELECT * FROM Category"; $stmt = $db->prepare($query); $stmt->execute(); $stmt->bind_result($id,$categoryName,$description,$pic,$active); while($stmt->fetch()) { echo'<li><a href="#">'.$categoryName.'</a> <!-- start mega menu --> <div class="cols3"> <div class="col1"> <ol>'; $dba = db_connect(); $Subquery = "SELECT * FROM Subcategory WHERE CategoryId = '".$id."'"; $Substmt = $dba->prepare($Subquery); $Substmt->execute(); $Substmt->bind_result($Subid,$CatId,$SubCategoryName,$SubDescription); while($Substmt->fetch()) { echo' <li><a href="#">'.$SubCategoryName.'</a></li>'; } echo' </ol> </div> <!-- end mega menu --> </li>'; } } </code></pre> <p>The only problem is that it returns all the subcategories on the the same <code><div class="col1"></code>:</p> <p><img src="https://i.stack.imgur.com/9ChgN.png" alt="enter image description here"></p> <p>what I would like to obtain is count the subcategories and if the result is more than 4 return the other items in the second and third column. </p> <p>UPDATE***: thanks to the answer below now the menu looks like this:</p> <p><img src="https://i.stack.imgur.com/mqKp4.png" alt="enter image description here"></p> <p>thanks!</p> |
1,398,344 | 0 | <p>Aside from changing your entity name, your options are really limited to name-aliasing and/or fully-qualifying the two colliding names, as you are already doing.</p> <p>My personal preference would be fully-qualifying both type names throughout the source. Your current approach is a mix of both aliasing and qualifying. You can also alternatively alias both types to something like:</p> <pre><code>using EntityImage = myCMS.Entities.Image; using DrawingImage = System.Drawing.Image; </code></pre> |
23,097,162 | 0 | <p>As suggested in the comments, the Array <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter" rel="nofollow">filter</a> method should give you what you want. Here's a start:</p> <pre><code>var filteredFilms = films.filter(function(film) { return parseInt(film.duration) > 150 && film.genre === 'Crime'; }); </code></pre> |
1,725,514 | 0 | Help me remove a Singleton: looking for an alternative <p>Background: I have some classes implementing a subject/observer design pattern that I've made thread-safe. A <code>subject</code> will notify it's <code>observers</code> by a simple method call <code>observer->Notified( this )</code> if the <code>observer</code> was constructed in the same thread as the notification is being made. But if the <code>observer</code> was constructed in a different thread, then the notification will be posted onto a <code>queue</code> to be processed later by the thread that constructed the <code>observer</code> and then the simple method call can be made when the notification event is processed.</p> <p>So… I have a map associating threads and queues which gets updated when threads and queues are constructed and destroyed. This map itself uses a mutex to protect multi-threaded access to it. </p> <p>The map is a singleton. </p> <p>I've been guilty of using singletons in the past because "there will be only one in this application", and believe me - I have paid my penance!</p> <p>One part of me can't help thinking that there really will be only one queue/thread map in an application. The other voice says that singletons are not good and you should avoid them. </p> <p>I like the idea of removing the singleton and being able to stub it for my unit tests. Trouble is, I'm having a hard time trying to think of a good alternative solution.</p> <p>The "usual" solution which has worked in the past is to pass in a pointer to the object to use instead of referencing the singleton. I think that would be tricky in this case, since observers and subjects are 10-a-penny in my application and it would very awkward to have to pass a queue/thread map object into the constructor of every single observer.</p> <p>What I appreciate is that I may well have only one map in my application, but it shouldn't be in the bowels of the subject and observer class code where that decision is made.</p> <p>Maybe this is a valid singleton, but I'd also appreciate any ideas on how I could remove it.</p> <p>Thanks.</p> <p>PS. I have read <a href="http://stackoverflow.com/questions/1300655/whats-alternative-to-singleton">What's Alternative to Singleton</a> and <a href="http://googletesting.blogspot.com/2008/08/where-have-all-singletons-gone.html" rel="nofollow noreferrer">this article</a> mentioned in the accepted answer. I can't help thinking that the ApplicationFactory it just yet another singleton by another name. I really don't see the advantage.</p> |
32,433,237 | 0 | <p>If you have associative array than You can use php built in function <code>extract()</code>. </p> <p>Example:</p> <pre><code>$abc = array('var1'=>2, 'var2'=>4, 'var3'=>6); extract($abc); echo $var1.$var2.$var3; //Outputs 246 </code></pre> |
36,406,419 | 0 | <p>u can use isEnabled() to verify whether it is enabled or disable.it returns boolean .if it returns true the element is enabled if it returns false the element is disabled.</p> |
40,701,314 | 0 | <p>You called a method that basically calls another method of the same signature </p> <pre><code>@Override public String userSignIn(String email, String password, String authType) throws Exception { login(email, password, authType, new OnLoginResponseCallback() { @Override </code></pre> <p>Instead, wherever you would call <code>userSignIn</code>, you call <code>login</code>, and pass in that anonymous class. You can't return from these inner methods, because that isn't how callbacks work. You use the parameters of the interface methods to "continue" your logic. Like, do login, callback to the main function with some user info, use this info to make a new request, have a callback waiting for that data, that passes back data to some other method. It's all <code>void</code> methods calling other methods. No <code>return</code> statements </p> <p>Although, in Javascript, you can read this </p> <p><a href="http://stackoverflow.com/questions/6847697/how-to-return-value-from-an-asynchronous-callback-function">How to return value from an asynchronous callback function?</a></p> |
33,371,936 | 0 | <p>No, a static method cannot call a non-static method.</p> <p>Consider that you have objects <code>a</code> and <code>b</code>, both instances of <code>Currency</code>. <code>currencyValidator</code> exists on those two objects. Now <code>store()</code> belongs to the class <code>Currency</code> itself, not one of those objects. So, in <code>Currency.store()</code>, how does it know which object to call <code>currencyValidator()</code> on? The simple answer is it doesn't so it can't. This is one of the pitfalls of using static methods and one of the reasons people often urge against them.</p> <p>Regardless, you can get around this by passing <code>a</code> into <code>Currency.store()</code>, and calling <code>a.currencyValidator()</code> instead.</p> |
1,195,551 | 0 | <p>I understand your concern. Even for trusted sources, PHP provides more access than is necessary to the whole environment of the web request. Even if the scripters are trusted and even if they can only harm themselves with a scripting error, a more constrained scripting environment would be easier for them to use and easier for you to support.</p> <p>You want something that can be sandboxed off, that can only access resources you explicitly assign to its scope, and that executes in a "play within a play" runtime environment rather than in PHP's own.</p> <p>One approach is to use a web templating language for user-submitted scripts. These provide a certain amount of control (variable assignment for example), and close off other options, for example you can't write an infinite loop. I've used Velocity for this purpose in Java applications; I think something like Smarty might work in PHP, but I don't have direct experience of using it for that purpose. </p> <p>Another approach, if what the scripts are required to do is constrained by the domain, is to implement a Domain Specific Language (DSL). I mentioned that in <a href="http://stackoverflow.com/questions/1171485/interpret-text-input-as-php/1172023#1172023">this answer</a>.</p> <p>Apart from that, I don't know of any pure-PHP implementations of scripting languages. It's something I'd be interested in myself.</p> |
364,590 | 0 | <p>Of additional interest is probably how good of a fit the line is. For that, use the Pearson correlation, here in a PHP function:</p> <pre><code>/** * returns the pearson correlation coefficient (least squares best fit line) * * @param array $x array of all x vals * @param array $y array of all y vals */ function pearson(array $x, array $y) { // number of values $n = count($x); $keys = array_keys(array_intersect_key($x, $y)); // get all needed values as we step through the common keys $x_sum = 0; $y_sum = 0; $x_sum_sq = 0; $y_sum_sq = 0; $prod_sum = 0; foreach($keys as $k) { $x_sum += $x[$k]; $y_sum += $y[$k]; $x_sum_sq += pow($x[$k], 2); $y_sum_sq += pow($y[$k], 2); $prod_sum += $x[$k] * $y[$k]; } $numerator = $prod_sum - ($x_sum * $y_sum / $n); $denominator = sqrt( ($x_sum_sq - pow($x_sum, 2) / $n) * ($y_sum_sq - pow($y_sum, 2) / $n) ); return $denominator == 0 ? 0 : $numerator / $denominator; } </code></pre> |
