40,897,840 | 0 | How to % encode single quotes when making jQuery AJAX call? <p>I am using $.ajax to send a SQL query to my web server. The query string contains several single quotes ('). I encountered a very messy problem on encoding single quotes.</p> <p>My code like this, please note the single quotes in query string:</p> <pre><code>var query = "select SID, age from Students where Name=\'Jason\'" + String.fromCharCode(10) + "order by age asc"; $.ajax({ url: "http://mywebserver/query", data: { env: "dbserver1", endTime: "getUTCDate()", startTime: "dateadd(hour, -336, getUTCDate())", text: query }, type: "GET", dataType: "json" }).done(function (datum) { }); </code></pre> <p>If I don't explicitly call encodeURIComponent before make AJAX call, jQuery will encode it for me, however, the single quotes are not encoded to %27 by default, so query doesn't work;</p> <p>If I pass an encoded query string to jQuery, it will encode again, that messes up the query string.</p> <p>The only solution i can imagine is, i have to overwrite the behavior how jQuery encodes URL, and replace all (') with %27. But I don't know if jQuery supports that. Does anyone have a solution for this?</p> |
24,968,975 | 0 | <blockquote> <p>Is it safe if I use the same variable to create another subprocess if previous subprocess finishes?</p> </blockquote> <p>Yes. It would also be safe if the subprocess <em>weren't</em> finished, since you're completely replacing the value stored in <code>p</code> with a new value (a new object reference).</p> <hr> <p><s>In fact, <em>your</em> assignment in the loop you've shown isn't overwriting the previous value at all. By the time a new iteration starts, since you've declared your variable <em>inside</em> the block, it's either a new variable on each iteration or it's treated as though it were (you can look at it either way, probably; the bytecode probably reflects the latter but I think theory reflects the former). <em>Your</em> assignment is giving the (new) variable an initial value, not overwriting the previous iteration's value. If you moved your <code>Process p</code> declaration outside the loop, <em>then</em> you'd be overwriting it. Which would still be fine. :-)</s></p> <p>The strikeout text above may be or may not be true in theory (I'd have to dig through the JLS), but it would appear <em>not</em> to be true in pragmatic JVM/bytecode terms: Test: <a href="http://pastie.org/9422290" rel="nofollow">http://pastie.org/9422290</a> Bytecode: <a href="http://pastie.org/9422293" rel="nofollow">http://pastie.org/9422293</a> (pasted below). We can see that the <code>Date</code> reference is stored on instruction 20 of <code>main</code> in local variable 2 (<code>astore_2</code>). We only write to it on the first iteration. It isn't cleared when starting the next iteration, so pragmatically, you're using the same variable and overwriting it.</p> <p><code>Temp.java</code>:</p> <pre><code>import java.util.Date; public class Temp { public static final void main(String[] args) { int counter; for (counter = 0; counter < 10; ++counter) { Date dt; if (counter < 1) { dt = new Date(); System.out.println(dt); } System.out.println("loop end"); } } } </code></pre> <p>Output of <code>javap -c Temp</code>:</p> <pre><code>public class Temp { public Temp(); Code: 0: aload_0 1: invokespecial #1 // Method java/lang/Object."<init>":()V 4: return public static final void main(java.lang.String[]); Code: 0: iconst_0 1: istore_1 2: iload_1 3: bipush 10 5: if_icmpge 42 8: iload_1 9: iconst_1 10: if_icmpge 28 13: new #2 // class java/util/Date 16: dup 17: invokespecial #3 // Method java/util/Date."<init>":()V 20: astore_2 21: getstatic #4 // Field java/lang/System.out:Ljava/io/PrintStream; 24: aload_2 25: invokevirtual #5 // Method java/io/PrintStream.println:(Ljava/lang/Object;)V 28: getstatic #4 // Field java/lang/System.out:Ljava/io/PrintStream; 31: ldc #6 // String loop end 33: invokevirtual #7 // Method java/io/PrintStream.println:(Ljava/lang/String;)V 36: iinc 1, 1 39: goto 2 42: return } </code></pre> |
17,594,551 | 0 | <p>In the XAML you're setting the property to the default value which will not cause the <code>PropertyChanged</code> handler to fire. The boilerplate Get and Set methods will never be called unless you call them from code because properties set in XAML call <code>GetValue</code> and <code>SetValue</code> directly (as is the case with wrapper properties on a normal DP).</p> <p>To ensure the change handler is always called when a value is set you could use a <code>Nullable<HorizontalAlignment></code> instead and set the default to <code>null</code>.</p> |
20,109,023 | 0 | <p>The problem is that your <code>fscanf</code> will never read the newline at the end of the first line. So when it is called the second time, it will fail (returning 0, not EOF) and read nothing, leaving <code>buffer</code> unchanged.</p> <p>You could add a call to <code>fscanf("%*[\n]");</code> at the end of your while loop to skip the newline (and any blank lines that might occur). Or you could just use <code>fgets</code> instead, which also makes it easier to avoid the potential buffer overflow problem.</p> |

A cache-miss is no reason to swap out a thread. A page-fault, where the desired page is not loaded into RAM at all, may cause a thread to be blocked until the page gets loaded from disk. The memory-management hardware does that by generating a hardware interrupt to an OS driver that handles the page-fault.</p> |

36,410,229 | 0 | Pattern for moving javascript out of the markup <p><strong>tl;dr</strong> How do I refactor a typical .NET+KnockoutJS site using lots of server generated blocks (controllers) into one where all js is loaded separately from the markup?</p> <p>Up until now all my foray into front-end development has been new projects, built from the ground using modern tooling and workflows, such as React, Redux, isomorphic rendering, etc. Yesterday a legacy project (ok, made three years ago) landed on my lap, and it features "blocks" (an EPi Server term basically meaning templates) such as this:</p> <p><strong>MySuperSlider.ascx</strong></p> <pre><code><!-- ko foreach: products() --> <div class="my-super-slider"> <a data-bind="attr: { href: ProductUrl }"> <h1 data-bind="text: name"></h1> <img src="" data-bind="attr: { src : image.uri }" </a> </div> <!-- /ko --> <script type="text/javascript"> // Make a call to the back-end to retrieve the product data used // in the KO template above and apply it ko.applyBindings(new SliderBlock( '<%# ProductsController.GetServiceUrl(ProductsController.BlockUrl, Request.Url)%>', '<%# CurrentPage.PageLink.ID %>', '<%# GetBlockId() %>', '<%# (CurrentPage as SitePageDataBase) == null?string.Empty:(CurrentPage as SitePageDataBase).ProductPageUrl %>?id=', '<%# ContentLanguageCode %>', "<%# SliderContentBlock.ClientID %>"), document.getElementById("<%# SliderContentBlock.ClientID %>")); </script> </code></pre> <p>Blocks, such as this one, are being reused all over the site, but with different settings (ref <code>SliderContentBlock.ClientID</code> which would fetch data for that current block). The fact that the referenced variables are unique for each block instance and rendered at runtime makes it impossible/hard to split the js out. Except possibly using some <code>data</code> attributes that could later be picked up?</p> <p><strong>Problem: <code><script></code> tags cannot be moved out of <code><head></code></strong></p> <p>It is currently impossible to move <code><script></code> tags out of <code><head></code>, thus blocking the rendering pipeline. Neither moving after them after <code><body></code> or using <code>async</code> or <code>defer</code> attributes is possible as this would make any inline <code><script></code> blocks referring to the <code>ko</code> variable break.</p> <p>So what is a good strategy for refactoring the above code into something that will work regardless of whether the knockout library has been loaded or not?</p> <p><strong>Hacky solution</strong></p> <p>The fastest (and probably most brittle) solution would be to create an array to hold initialization functions that could then be executed later on. Something like</p> <pre><code><head> <script>window.initFuncs = [];</script> </head> <body> ... <!-- inline code pushing init code in the queue --> ... <script>initFuncs.forEach( fn => fn() );</script> </body> </code></pre> <p>Then all I would need to do to defer execution of the above javascript would be to wrap it in a <code>window.initFuncs.push( () => { ko.applyBindings(/* js goes here */) })</code></p> <p>This would work, but does not exactly seem like the way to go. But this problem must have been solved a million times before (?). How does other Knockout developers do this?</p> <p>I cannot simply move <em>all</em> of the javascript (as it is) out into separate files, as variables are being inserted into the markup during server rendering.</p> <p><strong>Attempt at better solution</strong></p> <p>I am not a .NET developer, but I feel the logic in the template with all the variable substitution would be better done in the backing code, instead of pushing all the details into the front-end. Not sure how that would be done, though.</p> |

13,462,999 | 0 | <p>Dates in SQL are represented as #year/month/day#, eg. today's date would be #2012/11/19#, and to make DLookup work you have to use this syntax:</p> <pre><code>DLookup("HolidayDate", "Holidays", "HolidayDate=" & Format([EncDateTime],"\#yyyy/mm/dd\#")) </code></pre> <p>to check if today is holiday, you could use this:</p> <pre><code>DLookup("HolidayDate", "Holidays", "HolidayDate=" & Format(Date(),"\#yyyy/mm/dd\#")) </code></pre> <p>Yes, DLookup is slow, you should not use it in a query. To check if <code>EncDateTime</code> is a holiday, you should join <code>EncData</code> and <code>Holidays</code> togheter, with this SQL Code:</p> <pre><code>SELECT EncData.* FROM EncData INNER JOIN Holidays ON EncData.EncDateTime = Holidays.HolidayDate </code></pre> <p>This should return all EncData rows that are hoildays. It should, but it probably doesn't. Notice that EncDateTime contains not only the date, but also the time, so it doesn't match with HolidayDate that contains just the date. This works instead:</p> <pre><code>SELECT EncData.* FROM EncData INNER JOIN Holidays ON DateValue(EncData.EncDateTime) = Holidays.HolidayDate </code></pre> <p>And to extract all the rows in EncData, not just the holidays?</p> <pre><code>SELECT EncData.*, Holidays.HolidayDate FROM EncData LEFT JOIN Holidays ON DateValue(EncData.EncDateTime) = Holidays.HolidayDate </code></pre> <p>Notice that when HolidayDate contains a date only when that day is holiday, otherwise it will be NULL.</p> <p>These are just some basic ideas to start. But don't forget that you cans use wizards to make your query, then you can always see how your SQL code looks like.</p> |

27,610,914 | 0 | <p>It does not just happen for ng-repeat, this seems to happen for any other directives that creates a scope like <code>ng-if</code> as well. And it seems like, this is because the directive's isolated scope gets overwritten by the ng-repeat's child scope. And because of <code>replace:true</code> option ng-repeat becomes a part of the directive source element i.e <code><foo></foo></code> and the child scope of ng-repeat is calculated from the ultimate parent scope <code>MainCtrl</code> (Which appears to be wrong) and this causes the entire directive template to be bound to the child scope of controller and any interpolations are evaluated against that scope. Hence you see main controller's scope being expanded in the directive. This seems like a bug.</p> |

No, its not an actual date field unfortunately (ugghhh). What I need to do is make a view that has an exposed field that can pull content that is between 2 dates. For example I want to get all of the nodes who's date field is between 2012-09-01 and 2012-09-30. </p> <p>I'm guessing I could convert these fields using a computed field with <code>strtotime()</code>.

22,104,734 | 0 | Android Google Maps, how to create navigation between 2 points <p>I want to create a Map activity (FragmentActivity) that displays a Google Map and shows navigation between 2 points.</p> <p>I have one made that shows one location but I've no idea on how to create navigation to another point, every link I saw gives their web api as the solution (<a href="https://maps.google.com/maps?saddr=X,Y&daddr=X,Y" rel="nofollow">https://maps.google.com/maps?saddr=X,Y&daddr=X,Y</a>)</p> <p>and I want to do exactly what it does just programmatically through the activity and not just link into their webpage</p> <p>my code so far:</p> <pre><code>try{ bndl = getIntent().getExtras(); COORDS = new LatLng(bndl.getDouble("lat"), bndl.getDouble("long")); if (map == null) { map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap(); if (map != null) { map.setMapType(GoogleMap.MAP_TYPE_HYBRID); map.addMarker(new MarkerOptions().position(COORDS).title("Your parking spot!")); CameraPosition cameraPosition = new CameraPosition.Builder() .target(COORDS) .zoom(20) .bearing(90) .tilt(0) .build(); map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition)); } } } catch (Exception e){ Log.v("except", ""+e); } </code></pre> <p>now this only shows the one location (as it should do) but how to create another marker or something to navitage to? Is there a way to do this or do I HAVE to use their web api?</p> |

16,275,131 | 0 | <blockquote> <p>Am I missing something? How can I achieve the same thing in CodeIgniter?</p> <blockquote> <p><sub>if you want to learn how to truly approach MVC in PHP, you can learn it from Tom Butler <a href="http://r.je" rel="nofollow">articles</a></sub></p> </blockquote> </blockquote> <p>CodeIgniter implements Model-View-Presenter pattern, not MVC (even if it says so). If you want to implement a truly MVC-like application, you're on the wrong track.</p> <p>In MVP:</p> <ul> <li>View can be a class or a html template. View should never be aware of a Model.</li> <li>View should never contain business logic</li> <li>A Presenter is just a glue between a View and the Model. Its also responsible for generating output.</li> </ul> <blockquote> <blockquote> <p>Note: A model should never be <em>singular class</em>. Its a number of classes. I'll call it as "Model" just for demonstration.</p> </blockquote> </blockquote> <p>So it looks like as:</p> <pre><code>class Presenter { public function __construct(Model $model, View $view) { $this->model = $model; $this->view = $view; } public function indexAction() { $data = $this->model->fetchSomeData(); $this->view->setSomeData($data); echo $this->view->render(); } } </code></pre> <p>In MVC:</p> <ul> <li>Views are not HTML templates, but classes which are responsible for presentation logic</li> <li>A View has direct access to a Model</li> <li>A Controller should not generate a response, but change model variables (i.e assign vars from <code>$_GET</code> or <code>$_POST</code></li> <li>A controller should not be aware of a view</li> </ul> <p>For example,</p> <pre><code>class View { public function __construct(Model $model) { $this->model = $model; } public function render() { ob_start(); $vars = $this->model->fetchSomeStuff(); extract($vars); require('/template.phtml'); return ob_get_clean(); } } class Controller { public function __construct(Model $model) { $this->model = $model; } public function indexAction() { $this->model->setVars($_POST); // or something like that } } $model = new Model(); $view = new View($model); $controller = new Controller($model); $controller->indexAction(); echo $view->render(); </code></pre> |
1,298,071 | 0 | <p>You can do this easily in XeLaTeX:</p> <pre><code>\usepackage{fontspec} ... \fontspec[ItalicFont=*,ItalicFeatures=FakeSlant]{Minion Pro} </code></pre> <p>Highly undesirable, however, if there's any chance you can get a <a href="http://www.fonts.com/findfonts/detail.htm?pid=414411" rel="nofollow noreferrer">real italic</a>.</p> <p>Update: why undesirable? Because font outlines are not designed to be distorted! Any sort of transformation besides linear scaling in both directions will change the relationship between the inner/outer curves of the letters, effectively going against the wishes of the font designer.</p> <p>If you want to highlight something in a different font than the roman and not use italic, try something completely different like a harmonising sans serif, for example.</p> |
