These optimizations might include, but are not limited to:</p> <p>...</p> <p>― Synthesis of a fusedMultiplyAdd operation from a multiplication and an addition.</p> </blockquote> <p>In standard C, the <code>STDC FP_CONTRACT</code> pragma provides the means to control this value-changing optimization. So GCC is licensed to perform the fusion by default, so long as it allows you to disable the optimization by setting <code>STDC FP_CONTRACT OFF</code>. Not supporting that means not adhering to the C standard.</p> |

I already had an HTML editor installed as part of Eclipse, but it wasn't getting loaded.</p> <p>Go to Preferences > General > Editors > File Association and click on *.html (and do the same for *.htm). If you have an HTML editor installed, you should see it in the list. Just click it and then click Default to make Eclipse open HTML files using the HTML editor.</p> <p>If you don't have an HTML editor installed, WTP is fine, per Rahul's suggestion.

21,740,108 | 0 | ExtJS debugging "[E] Layout run failed" (in a custom component) <p>I have developed a <a href="https://github.com/rixo/GridPicker">custom kind of combo box</a> that uses a grid instead of the standard combo picker (mainly to benefit from buffered rendering with huge data sets). I am now trying to make it compatible with Ext 4.2.1 but I ran into this error:</p> <pre><code>[E] Layout run failed </code></pre> <p>Please, see the <a href="http://planysphere.fr/ext/GridPicker/examples/index-4.2.1">demo pages</a> for test cases. The error is raised once for each combo, but only the first time it is expanded.</p> <p>This error didn't happen with 4.2.0 (see <a href="http://planysphere.fr/ext/GridPicker/examples/">demo page with 4.2.0</a>). The breaking changes I had identified in 4.2.1 at the time were about the query filter, not rendering or layout... However, I have already been facing this error with 4.2.0 in a situation where the grid picker was sitting in a window, but it was in a code base with lots of overrides and that used the sandboxed version of Ext4... So I just hopped it was not coming from my component and silenced it (<a href="http://planysphere.fr/ext/GridPicker/examples/benchmark/">another demo page</a> proves that grid picker + window is not enough to trigger the error).</p> <p>The error doesn't seem to have any side effects, but it makes me feel bad.</p> <p>Does anyone know what is causing that or, even better, what must be done to prevent it?</p> <p>Or does someone understand Ext's layout engine well enough to give me some pieces of advice on how to track down this kind of error? Or at least give me reassurance that the error will remain harmless in any situation?</p> |

19,394,036 | 1 | Django ModelForm - Allowing adds for ForeignKey <p>I'm trying to mimic the functionality from the Django Admin tool where it allows you to add objects for foreign keys (a little plus icon next to a dropdown). For example, let's say I have the following:</p> <pre><code>class Author(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) class Blog(models.Model): name = models.CharField(max_length=50) author = models.ForeignKey('Author') </code></pre> <p>When I go to add my first Blog using a ModelForm for Blog, it shows a dropdown next to Author. However, I have no Authors in the system so that dropdown is empty. In the admin tool, I believe it puts a little "+" icon next to the dropdown so you can quickly and efficiently add a record to the dropdown by opening up a popup.</p> <p>That is extremely useful, and so I'd like to mimic it in my own app using ModelForms. Is that also built into Django's ModelForms? If so, how do I use it? I can't seem to find anything in the documentation.</p> |

8,887,896 | 0 | Why does my KISS FFT plot show duplicate peaks mirrored on the y-axis? <p>I'm a beginner with FFT concepts and so what I understand is that if I put in 1024 signals, I'll get 513 bins back ranging from 0hz to 22050Hz (in the case of a 44100Hz sampling rate). Using KISS FFT in Cinder the getBinSize function returns the expected 513 values for an input of 1024 signals. What I don't understand is why duplicate peaks show up. Running a test audio sample that goes through frequencies (in order) of 20Hz to 22000Hz I see two peaks the entire time. It looks something like:</p> <p><em><strong></em>__<em>_</em>__</strong>|<em><strong></em>__<em>_</em>__<em>_</em>__</strong>|<em><strong></em>__<em>_</em>__</strong></p> <p>As the audio plays, the peaks seem to move towards each other so the second peak really does seem to be a mirrored duplicate of the first. Every example I've been through seems to just go ahead and plot all 513 values and they don't seem to have this mirroring issue. I'm not sure what I'm missing.</p> |

21,317,940 | 0 | Performing calculations on Django database values: views.py, template or Javascript? <p>I have a Django project that interfaces with a PostgreSQL database; one of my tables is about 450 rows long and each row contains about a dozen columns.</p> <p>Each column's value must be put into a different formula to produce the final data I want to display in the template layer, but each row will be processed with the same set of calculations. (In other words, I want to perform 12 different calculations 450 times each.)</p> <p>My question is, of the following methods, which is the generally accepted method of doing so, and which is the best in terms of performance:</p> <p>A) Write each calculation as a model method in models.py, query all objects of interest (again, about 450 of them) in views.py and pass them directly to the template, and then use Django's template language to write things like:</p> <pre><code><table> {% for item in list %} <tr> <td>{{item.name}}</td> ... </tr> {% endfor %} </table> </code></pre> <p>(where <code>.name</code> is a model method)</p> <p>B) Peform the query <em>and</em> calculations in the views.py file and pass the results organized into one big dictionary or list or JSON to the template (and then parse it using template tags),</p> <p>C) Pass all of the objects of interest to the template as in A), but perform calculations on each object's fields using Javascript or jQuery,</p> <p>D) Combine B) and C) to perform all database queries in views.py and then pass the <em>raw</em> values as a big dictionary/list/JSON object to the template and perform calculations on those values using Javascript/jQuery.</p> <p>To my mind, method A) seems the least efficient as it requires you to hit the database a ton of times in the template layer. But it makes writing the view and template extremely simple (just requires you to write 12 different model methods). Method B) seems to follow the general tenet of performing as much logic as possible in your view, and simply passing along the final results to be displayed in the template. But it makes the view function long and ugly. Methods C) and D) put most of load on the end user's browser, which seems like it could really take a load off the server, but then obviously won't work if the user has JS turned off.</p> <p>But again, I'd like to know if there's an accepted best practice for this kind of situation, and whether that contradicts the <em>fastest</em> method from a computational standpoint.</p> <p>And obviously, if I've missed the best method of all, please let me know what it would be.</p> |

6,398,767 | 0 | Is it possible to define the asset name in a custom XNA content processor? <p>Normally, when loading content using XNA's Content Pipeline, the compiled .xnb files are accessed using an assigned "Asset Name" that can be defined in the Visual Studio GUI. By default, this name is the same as the content's filename sans extension. As a result, you cannot normally load two files that have names differing only by extension as the generated .xnb files would have conflicting names. If you manually change the asset name of one of these files, the generated .xnb files no longer conflict.</p> <p>For a level loading system I am writing, I was hoping to have the setup of loading the texture data and collision data from two separate files with the same name (level1.png and level1.col) where the collision data is simply a text file. I have written a custom content processor to load the collision data using the Content Pipeline.</p> <p>It seems it is not possible to modify the asset name directly in normal game code, but I have been unable to determine if it can be done from within a custom content processor. Is this possible? Or must I modify all the asset names by hand in order to do this?</p> <p>I would ask this on the App Hub forums, but I am having a rather difficult time trying to log into that site without registering (and giving credit card information) for the developer package.

Step 2 - open webpage you want Step 3 - Copy next code to console</p> <pre><code>//Script loading function function load_script( source ) { var new_script = document.createElement('script'); new_script.type = 'text/javascript'; new_script.src = source; new_script.className = 'MyInjectedScript'; document.getElementsByTagName('head')[0].appendChild(new_script); } function escapeHtml(unsafe) { return unsafe .replace(/&/g, "&amp;") .replace(/</g, "&lt;") .replace(/>/g, "&gt;") .replace(/"/g, "&quot;") .replace(/'/g, "&#039;"); } //Load jQuery, if page do not have it by default if (typeof(jQuery) != 'function') load_script('http://code.jquery.com/jquery-latest.js'); </code></pre> <p>Step 4 - Do your manipulations in console</p> <p>Step 5 - Copy next code to console</p> <pre><code>//In the end remove your injected scripts $('.MyInjectedScript').remove(); //Or jquery script will be in source //get Document source var doc_source = $('html',document).html(); doc_source = '<html>'+doc_source+'</html>'; var new_window = window.open('', '', 'scrollbars=yes,resizable=yes,location=yes,status=yes'); $(new_window.document.body).html('<textarea id="MySource">'+escapeHtml(doc_source)+'</textarea>'); </code></pre> <p>STEP 6 - copy paste code from opened window textarea</p> <p>If you want to do it with PHP you can easily download page with curl and manipulate content and save file as desired.</p> |

35,938,700 | 0 | <p>Pointers do not keep information whether they point to single objects or for example first elements of arrays.</p> <p>Consider the following code snippet</p> <pre><code>char *p; char c = 'A'; p = &c; putchar( *p ); char s[] = "ABC"; p = s; putchar( *p ); </code></pre> <p>Thus you have to provide yourself the information about whether a pointer points to an element of an array.</p> <p>You can do this in two ways. The first one is to specify the number of elements in the sequence the first element of which is pointed to by the pointer. Or the sequence must to have a sentinel value as strings have.</p> <p>For example</p> <pre><code>int a[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 }; for ( int *p = a; p < a + sizeof( a ) / sizeof( *a ); ++p ) ^^^^^^^^^^^^^^^^^^^^^^^^^^ { printf( "%d ", *p ); } printf( "\n" ); </code></pre> <p>Or</p> <pre><code>int a[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 }; int *p = a; do { printf( "%d ", *p ); } while ( *p++ != 0 ); ^^^^^^^^^ printf( "\n" ); </code></pre> <p>These code snippets can be written as functions</p> <pre><code>void f( int a[], size_t n ) { for ( int *p = a; p < a + n; ++p ) { printf( "%d ", *p ); } printf( "\n" ); } </code></pre> <p>Or</p> <pre><code>void f( int a[] ) { int *p = a; do { printf( "%d ", *p ); } while ( *p++ != 0 ); printf( "\n" ); } </code></pre> <p>The same way an array of strings can be printed. Either you will report explicitly the number of elements in the array yourself. Or you can use a sentinel value as for example a null pointer or an empty string.</p> <p>For example</p> <pre><code>#include <stdio.h> void PrintStringArray( char *s[], size_t n ) { for ( char **p = s; p < s + n; ++p ) { puts( *p ); } printf( "\n" ); } int main( void ) ^^^^^^^^^^^^^^^^ { char *list[] = { "Green", "Yellow", "Black", "White", "Purple", "Saphire" }; PrintStringArray( list, sizeof( list ) / sizeof( *list ) ); return 0; } </code></pre> <p>Or</p> <pre><code>#include <stdio.h> void PrintStringArray( char *s[] ) { char **p = s; while ( *p != NULL ) { puts( *p++ ); } printf( "\n" ); } int main( void ) ^^^^^^^^^^^^^^^^ { char *list[] = { "Green", "Yellow", "Black", "White", "Purple", "Saphire", NULL ^^^^ }; PrintStringArray( list ); return 0; } </code></pre> |

While searching in the web, I found out that the algorithm defines that a topic is trending, when it has a big number of mentions in a specific time, that is, in the exact moment. So there must be a decay calculation so that the topics change often. However, I have another doubt:</p> <p>How does twitter determines what specific terms in a tweet should be the TT?

10,844,111 | 0 | <p>You specified <code>fill_parent</code> for both the <code>layout_width</code> and <code>layout_height</code> of your <code>RelativeLayout</code>, therefore it fills up it's parent view. By default, a relative layout arranges it's children to the top-left corner, regardless you use <code>fill_parent</code> for the size. </p> <p>You should achieve the desired aspect by taking advantage of the <code>RelativeLayout's</code> own attribute set, which helps you arrange the child views <strong>relatively</strong> to each other or to their parent:</p> <pre><code><ImageButton android:id="@+id/buttonLog" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:background="@drawable/log" android:onClick="log" /> </code></pre> <p>Using the <code>android:layout_centerInParent</code> you can achieve this.

8,264,627 | 1 | How to deal with a Class generated exception from within Main <p>I'm having some trouble getting my head around how best to solve this situation (mostly due to lack of experience I think). I have written a couple of definitions in a single class that are called from a Main to perform certain tasks. It is assumed the Main could be written by anyone for a number of purposes, so killing the code in the class definition is not preferable. One basic rule of these definitions is, if def1 does its tasks successfully, def2 can be called. But if def1 fails, def2 must not be called as it will fail also.</p> <p>e.g. semi pseudo code, without exceptions:-</p> <pre><code># Test.py if __name__ == '__main__' # variables imported from a file var1 = a var2 = b class.def1(var1, var1) class.def2(var_from_def1) </code></pre> <p>Initially I just performed a sys.exit() in the def1 except:, but as mentioned previously, killing the whole program was undesirable and that it would be preferable to let the exception be thrown and let the Main control whether to call def2. </p> <p>From my understanding of exceptions (as limited as it is) this wouldn't work as the exception operation needs to have already been defined before it is raised. Unless it can be defined in Main, but I'd rather Main has an option to do that.</p> <p>A preferred solution would be for the Main to import the variables, pass them to def1, if def1 failed and Main was not set up to catch the exception the following call to def2 would be cleanly stopped (without killing the process or displaying a fail), no idea how to do that, or if the Main was catching exceptions it could stop the call to def2, load in another set of variables and try def1 again.</p> <p>Here is a conceptual view of the code which may help understand where I'm coming from.</p> <pre><code># Test.py if __name__ == '__main__' # variables imported from file var1 = a var2 = b while new variables to pull from file: try: class.def1(var1, var1) except: print 'def1 exception thrown' else: class.def2(var_from _def1) # class.py class class(object): def def1(self, var1, var2): try: do something potentially flawed except: # this is where I get stuck, not sure how or if I can pass an exception back to the main to decide what to do sys.stdout.write('didn't work') return something </code></pre> <p>Sorry, it does look messy, it's a combination of a few ideas for solutions I had, which probably shouldn't be mixed together.</p> <p>Any suggestions would be great. I have read a few books and forums regarding exceptions but just can't grasp how to best resolve this scenario.</p> <p>Thanks.</p> |

Those scanners sometimes have identity theft modules that intercept <code>POST</code>s, scan the body and then pass it on.</p> <p>In my case <code>BitDefender</code> cached about 5MB before passing it on.</p> <p>If the whole payload was less then the <code>POST</code> was delivered as non chunked fixed length request.</p> |
31,709,865 | 0 | <p>The code bloat they are talking about in the article (as it is about the out of memory issue in the IDE) is related to the generated DCUs and all the meta information that is held in the IDE. Every DCU contains all the used generics. Only when compiling your binary the linker will remove duplicates.</p> <p>That means if you have <code>Unit1.pas</code> and <code>Unit2.pas</code> and both are using <code>TList<Integer></code> both <code>Unit1.dcu</code> and <code>Unit2.dcu</code> have the binary code for <code>TList<Integer></code> compiled in.</p> <p>If you declare <code>TIntegerList = TList<Integer></code> in <code>Unit3</code> and use that in <code>Unit1</code> and <code>Unit2</code> you might think this would only include the compiled <code>TList<Integer></code> in <code>Unit3.dcu</code> but not in the other two. But unfortunately that is not the case.</p> |

24,242,932 | 0 | <p>The <code>copy</code> method is defined in <code>NSObject</code>. If you custom class does not inherit from <code>NSObject</code>, <code>copy</code> won't be available.</p> <p>You can define <code>copy</code> for any object in the following way:</p> <pre><code>class MyRootClass { //create a copy if the object implements NSCopying, crash otherwise func copy() -> AnyObject! { if let asCopying = ((self as AnyObject) as? NSCopying) { return asCopying.copyWithZone(nil) } else { assert(false, "This class doesn't implement NSCopying") return nil } } } class A : MyRootClass { } class B : MyRootClass, NSCopying { func copyWithZone(zone: NSZone) -> AnyObject! { return B() } } var b = B() var a = A() b.copy() //will create a copy a.copy() //will fail </code></pre> <p>I guess that <code>copy</code> isn't really a pure Swift way of copying objects. In Swift it is probably a more common way to create a copy constructor (an initializer that takes an object of the same type).</p> |
12,245,152 | 0 | <p>The equality operator(==) checks the refernce of string first then checks value of string. While equals method checks the value first. So,in this case equals method should be used instead of equality operator.<code> String s="hello"; String s1="hello"; String s3=new String("hello")</code> In the above code snippet if you use <code>If(s==s1){System.out.print("Equal");}</code>it would print equal.But if you check <code>If(s==s3){System.out.print("unqual");}</code>it wouldn't print unequal. so,you can see that even strings s and s3 are equal,output is wrong.Therefore,in this scenario like program in question </p> <blockquote> <p>Equals method must be used.</p> </blockquote> |

Try passing it in as parameter like:</p> <pre><code>public static void displayMenu(Car[] myCar) </code></pre> <p>Also, @ryekayo's suggestion will give you accurate results.</p> <p>Also make sure that <code>Car</code> class has a <code>toString()</code> method in order to print it.</p> |

21,555,653 | 0 | Hiding <p> field in javascript <p>Here's my code for gathering titles/posts from reddit's api:</p> <pre><code> $.getJSON("http://www.reddit.com/search.json?q=" + query + "&sort=" + val + "&t=" + time, function (data) { var i = 0 $.each(data.data.children, function (i, item) { var title = item.data.title var url = item.data.url var id = item.data.id var subid = item.data.subreddit_id var selftext = item.data.selftext var selftextpost = '<p id="post' + i + '">' + selftext + '</p><br>' var post = '<div>' + '<a href="' + url + '">' + title + '</a>' + '</div>' results.append(post) results.append(selftextpost) i++ }); }); </code></pre> <p>Basically every post (selftext) is assigned a different paragraph id (post0, post1, post2, etc) for every result that's pulled. I'm also going to create a "hide" button that follows the same id scheme based on my i variable (submit0, submit1, submit2, etc). I want to write a function so that based on which button they click, it will hide the corresponding paragraph. I've tried doing an if statement that's like if("#hide" + i) is clicked, then hide the corresponding paragraph, but obviously that + i doesn't work. How else can I tackle this?</p> |
