10,004,738 | 0 | Entity Framework: Get Model with Linked Models in Many to Many Relationship <p>I'm coming from TSQL + C# land and have been trying to adapt to linq and EF. Many-to-many relationships have been tripping me up. I have models with many-to-many relationships that I want to query from a database. Such as:</p> <pre><code> class Product{ public int ID {get;set;} public string ProductName {get;set;} public virtual ICollection<Tag> Tags {get;set;} } class Tag { public int ID {get;set;} public string TagName {get;set;} public virtual ICollection<Product> Products {get;set;} } </code></pre> <p>I'm able to get a product itself out of the DbContext, and then later fetch it's associated Tags like this:</p> <pre><code>// product exists in memory as a Product with an empty product.Tags var query = from p in db.Product from t in db.Tags where p.ID == product.ID select p.Tags; </code></pre> <p>Then I can assign the product.Tags with the fetched Tags. Obviously, this is very inefficient when dealing with multiple products if I have to query for every product.</p> <p>With linq and EF, I want to be able to get a Product with all of its associated Tags in one round trip to the database. Also, I want to be able to get all Products and their associated Tags (or a filtered list of Products). How do would the linq look?</p> <p>Edit:</p> <p>Ok, after some more fiddling around, I've got this:</p> <pre><code>var query = db.Product.Include("Tags") .Where(p => p.Tags.Any(t => t.Products.Select(m => m.ID).Contains(p.ID))); </code></pre> <p>This is almost what I need. The results are all products with tags. Missing are the products that don't have tags. I think of this as the equivalent of a SQL inner join. I want to left outer join the tags to the product, and return all products with tags optional. How to get all products with their associated tags without excluding products that have no tags?</p> <p>Edit:</p> <p>This was easier than I thought.</p> <pre><code>var query2 = db.Product.Include("Tags").DefaultIfEmpty(); </code></pre> <p>This gets all the products and their respective tags, including products without tags. Hopefully it works for the right reasons...</p> |

16,886,701 | 0 | <p>You have both the option. You could stream data directly from Amazon S3 or first copy it to HDFS and then process it locally. The first way is good if you only intend to read the data once. And if your plan is to query the same input data multiple times, then you'd probably want to copy it to HDFS first.</p> <p>And yes, by using S3 as an input to MapReduce you lose the data locality optimization. Also, if your plan is to use S3 as a replacement for HDFS, I would recommend you to go with <code>S3 Block FileSystem</code> instead of <code>S3 Native FileSystem</code> as it imposes a limit of 5GB on file size.</p> <p>HTH</p> |
24,801,216 | 0 | Error: [$rootScope:inprog] $digest already in progress using angular.copy <p>I have an input field with a ng-blur function. My blur function uses Restangular to do a customPUT to the server and then does an angular.copy. It seems the line that causes the error is the angular.copy.</p> <p>Input field:</p> <pre><code><input type="text" ng-model="le.instance.from" ng-blur="blurField(le.instance.from, $event)"> </code></pre> <p>Blur handler</p> <pre><code>$scope.blurField = function (fieldNewValue, event) { $scope.le.instance.customPUT({markSaved: true}).then(function(){ angular.copy($scope.le.instance, $scope.leSaved); }); }; </code></pre> <p>The line causing the problem is the angular.copy one.

In that case I don't use the minified CSS and edit it, commenting out the part where the glyphicons generally are defined (references to the font resources). As the icons are the same in every theme you can get this won't do any harm and the icons keep working.

7,772,630 | 0 | Preventing browser loop <p>I've created an app that opens when clicking a specific URL. Obviously I've got something like this:</p> <pre><code> <intent-filter> <data android:scheme="http" android:host="example.com"/> <action android:name="android.intent.action.VIEW"/> <category android:name="android.intent.category.BROWSABLE"/> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </code></pre> <p>So that's all great, whenever somebody clicks a link with <a href="http://example.com/whatever/stuff" rel="nofollow">http://example.com/whatever/stuff</a>... it'll open my app. However, within my app, after doing some stuff, I want to send the suer back to the default browser (or whichever browser/web view they were using when they clicked the link to begin with). My problem is that I end up creating a loop:</p> <ol> <li>User clicks link <a href="http://example.com/xxx" rel="nofollow">http://example.com/xxx</a> and my app opens.</li> <li>My app does stuff, and now wants to send the user to a different URL, eg. <a href="http://example.com/yyy" rel="nofollow">http://example.com/yyy</a></li> <li><p>The intent that my app sends, ends up just going back to itself (my app).</p> <pre><code>Intent httpIntent = new Intent(Intent.ACTION_VIEW); String theNewURL = http://example.com/yyy; httpIntent.setData(Uri.parse(theNewURL)); startActivity(httpIntent); </code></pre></li> </ol> <p>How can I get my <code>httpIntent</code> to use the default browser (or wherever the user came from to begin with) instead of calling my app again?</p> <p>Edit: I've been able to solve the problem in a make-shift way, by making a CNAME record of one of my own domains (as a sort of alias) that goes to the same spot as <a href="http://example.com" rel="nofollow">http://example.com</a>. It sucks because the user now sees a different URL, but it still works in that it doesn't invoke the intent. (Am I even using the right language when I talk about intents?)</p> |

18,265,067 | 0 | <blockquote> <p>But why does writing to the index of "b" change the id.</p> </blockquote> <p>Because they're different things now. If you were to check <code>a</code>, <code>a[0]</code> is still <code>1</code> rather than <code>99</code> because <code>b</code> was a copy. If you didn't want this behavior, you wouldn't do the copy:</p> <pre><code>>>> a = [1,2,3] >>> b = a >>> b[0] = 99 >>> a[0] 99 </code></pre> <p>instead, you have this:</p> <pre><code>>>> a = [1,2,3] >>> b = a[:] >>> b[0] = 99 >>> a[0] 1 </code></pre> <p>Since you tagged <code>deepcopy</code>...it's something that only matters if your lists themselves contain mutable arguments. Say, for instance, you had:</p> <pre><code>>>> from copy import deepcopy >>> a = [[1,2],[3,4]] >>> b = a >>> c = a[:] >>> d = deepcopy(a) </code></pre> <p>So <code>a</code> is <code>b</code>, <code>c</code> is a shallow copy, and <code>d</code> is a deep copy.</p> <pre><code>>>> b[0] = 3 >>> a [3, [3,4]] >>> c [[1,2], [3,4]] >>> d [[1,2], [3,4]] </code></pre> <p><code>b</code> is the same as <code>a</code>, but the copies were unaffected.</p> <pre><code>>>> c[1][1] = 'hi' >>> a [3, [3, 'hi']] >>> c [[1, 2], [3, 'hi']] </code></pre> <p>If you replace the entries of <code>c</code>, <code>a</code> is unaffected. But if you still have the original lists <em>within</em> the entries, modifying one still shows up in the other. The nested lists are still the same.</p> <pre><code>>>> d[1][1] = 10 >>> a [3, [3, 'hi']] >>> d [[1, 2], [3, 10]] </code></pre> <p>Since <code>d</code> was a deep copy, it copied the list as well as its nested lists, so we can modify it <em>and its elements</em> at will without worry about messing up the other copies.</p> |

7,116,644 | 0 | <p>Like most programming techniques, nested functions should be used when and only when they are appropriate.</p> <p>You aren't forced to use this aspect, but if you want, nested functions reduce the need to pass parameters by directly accessing their containing function's local variables. That's convenient. Careful use of "invisible" parameters can improve readability. Careless use can make code much more opaque.</p> <p>Avoiding some or all parameters makes it harder to reuse a nested function elsewhere because any new containing function would have to declare those same variables. Reuse is usually good, but many functions will never be reused so it often doesn't matter.</p> <p>Since a variable's type is inherited along with its name, reusing nested functions can give you inexpensive polymorphism, like a limited and primitive version of templates.</p> <p>Using nested functions also introduces the danger of bugs if a function unintentionally accesses or changes one of its container's variables. Imagine a for loop containing a call to a nested function containing a for loop using the same index without a local declaration. If I were designing a language, I would include nested functions but require an "inherit x" or "inherit const x" declaration to make it more obvious what's happening and to avoid unintended inheritance and modification.</p> <p>There are several other uses, but maybe the most important thing nested functions do is allow internal helper functions that are not visible externally, an extension to C's and C++'s static not extern functions or to C++'s private not public functions. Having two levels of encapsulation is better than one. It also allows local overloading of function names, so you don't need long names describing what type each one works on.</p> <p>There are internal complications when a containing function stores a pointer to a contained function, and when multiple levels of nesting are allowed, but compiler writers have been dealing with those issues for over half a century. There are no technical issues making it harder to add to C++ than to C, but the benefits are less.</p> <p>Portability is important, but gcc is available in many environments, and at least one other family of compilers supports nested functions - IBM's xlc available on AIX, Linux on PowerPC, Linux on BlueGene, Linux on Cell, and z/OS. See <a href="http://publib.boulder.ibm.com/infocenter/comphelp/v8v101index.jsp?topic=%2Fcom.ibm.xlcpp8a.doc%2Flanguage%2Fref%2Fnested_functions.htm" rel="nofollow">http://publib.boulder.ibm.com/infocenter/comphelp/v8v101index.jsp?topic=%2Fcom.ibm.xlcpp8a.doc%2Flanguage%2Fref%2Fnested_functions.htm</a></p> <p>Nested functions are available in some new (eg, Python) and many more traditional languages, including Ada, Pascal, Fortran, PL/I, PL/IX, Algol and COBOL. C++ even has two restricted versions - methods in a local class can access its containing function's static (but not auto) variables, and methods in any class can access static class data members and methods. The upcoming C++ standard has lamda functions, which are really anonymous nested functions. So the programming world has lots of experience pro and con with them.</p> <p>Nested functions are useful but take care. Always use any features and tools where they help, not where they hurt.</p> |

I wrote myself a little C# application with an async server and I understand most of it, except for the following:</p> <p>So the server has a port it listens on for connections then when it receives a connection it creates a different socket to do the communication on. This it what I dont understand... How does the communication happen between the client and the server when in theory the client has no idea what port has been elected for this new connection?</p> <p>Thanks for all your answers</p> <p>Edit: As far as I understand the listening thread listens on the default port, but all messages are then handled on a different socket for each client?</p> <p>Edit Again: Some how you guys are misunderstanding my question. I understand normal socket communication. My problem is with an async server where the listening socket is different from the connecting socket. Ie. </p> <ol> <li>Server listens on default port</li> <li>Client attrmpts to connect.</li> <li>Server receiver request.</li> <li><strong>Server then creates a communication socket between client and server and continues listening on the default port.</strong></li> </ol> <p>My problem is at the last step. How does the client now know how to communicate on the new socket?

When I test the application using chrome, with no security (chromium-browser --allow-file-access-from-files --disable-web-security) I get an 406 error from the API.</p> <p>I've performed some tests, and the problem is solved when I add ".json" to the url, however, this is not easy to manage inside backbone.</p> <p>Any one has experienced the same error?</p> <p>UPDATE solution found at: <a href="http://stackoverflow.com/questions/9241045/backbone-client-with-a-remote-rails-server">BackBone client with a remote Rails Server</a></p> |

I have not installed the Windows 7 SDK, as <a href="http://blogs.msdn.com/windowssdk/archive/2009/06/15/installing-win-7-sdk-rc-and-vs2008-rtm-can-disable-vc-configuration-platform-choices.aspx" rel="nofollow noreferrer">Microsoft suggests might be the issue</a>. The problem is that there are no x64/64-bit choices in the Configuration Manager of Visual Studio. </p> <p>I do not have the "Microsoft Visual C++ Compilers 2008 Standard Edition" suggested in the link above installed on my computer. Any ideas what might fix this?</p> <p>I have checked that I have the x64 compiler and tools installed with Visual Studio.</p> <p><strong>Solution found</strong>: Uninstall VS completely and reinstall. Issue resolved after SP1 installed (again). Very strange.</p> |
37,508,854 | 0 | <p><code>replace()</code> will return a new <code>String</code> where ALL occurrences of a particular character are changed, not just a character at a particular position. So your problem is that the repeated <code>replace()</code> statements are effectively modifying the values back and forth.</p> <p>Because a <code>String</code> is immutable, you cannot simply replace its characters with others dynamically. So, convert your code to use a <code>StringBuilder</code> instead.</p> <pre><code>StringBuilder buildSample = new StringBuilder(); buildSample.append(sample); </code></pre> <p>Now you can use <code>setCharAt()</code> instead of <code>replace()</code> to change the character at one position at a time.</p> <pre><code>buildSample.setCharAt(i, 'A'); </code></pre> <p>At the end, you can return <code>buildSample.toString()</code>.</p> <p>As for changing each letter A to F to its complement, if only these six letters are required, a hard-coded function with a <code>switch</code> statement would do. Otherwise you can use a function like <code>complementaryLetter()</code> below, which returns the complement after checking the ASCII value of the character. This will work for all characters. You can add code to handle invalid cases, for non-character input.</p> <p><strong>A complete working code:</strong></p> <pre><code>public class Replace { public static void main(String[] args) { String s1 = "ABCDEFA"; System.out.println(s1); s1 = changeSample(s1); System.out.println(s1); } public static char complementaryLetter(char letter) { char retChar = 'A'; if ((int) letter % 2 == 0) retChar = (char) ((int)letter - 1); else retChar = (char) ((int) letter + 1); return retChar; } public static String changeSample(String sample) { StringBuilder buildSample = new StringBuilder(); buildSample.append(sample); for (int i = 0; i < sample.length(); i++) { buildSample.setCharAt(i, complementaryLetter(sample.charAt(i))); } return buildSample.toString(); } } </code></pre> |

3,488,578 | 0 | Is SMS data 8 bits until transmitted? <p>A lot of what I have recently read about SMS uses a specification of 140 octet characters, where most uses of SMS I am aware of use 160 septet characters. A UDH is 5 octets long, meaning if I want to send concatenated SMS I would only have 135 octet characters for my message data. This would allow me 154 septet characters after the UDH. </p> <p>Do I take a 154 octet character message, append it to the 5 octet UDH, and send this to the modem as the message text, or do I have to encode my 154 message octet characters into a 7 bit character string, encode the UDH as a 7 bit string, concatenate the two, and send that text to the modem?</p> |
5,367,067 | 0 | Do share buttons (facebook, stumbleupon, twitter, etc) incur a page-load penalty from Google? <p><strong>Our site saw traffic from Google drop significantly yesterday (only 5% traffic left in overnight)</strong>. I asked around. People say that site loading performance could caused the issue.</p> <p>I've looked at the performance. Site is loading in 1 or 2 seconds if no external links such as Google ads or share button. I cannot improve the Google Ads.</p> <p>For the share button, if you view the site <strong>Multiple Share buttons</strong> are loaded and it takes long time to load all of them. But, <strong>All of them are loaded in iframe</strong> (iframe page to different page but in same domain) to avoid slowing down page load.</p> <p>I think users are OK with this because all pages are loaded fast except the share buttons which come from each service site.</p> <p>But, my concern is that if <strong>Google care about all site loading including those in iframe</strong>, then it's big problem since it takes 10 seconds. If not, I will keep those share buttons.</p> <p><strong>Should I keep the share buttons or need to get rid of those?</strong> (I used addthis, it's super slow. And I added each buttons myself)</p> |

10,383,742 | 0 | <p>glPushClientAttrib(GL_CLIENT_VERTEX_ARRAY_BIT) saves all the client side states for all vertex array attributes. So everything you set with the glEnableClientState/glDisableClientState and gl*Pointer functions. It won't copy the actual data. It also won't save anything set with glBindBuffer/glBufferData because those would be server side states. There's probably an enum for glPushAttrib for that in normal OpenGL (no glPushAttrib in OpenGL ES either).</p> <p>I'm guessing that the difference between VBO and vertex array here is that VBOs have their actual data in graphics memory, while vertex arrays have to be streamed to the graphics card when you draw them. Pointers and enabled flags will still be saved with glPushClientAttrib when you are using VBOs, though.</p> <p>For OpenGL ES you have to keep track of the states yourself if you want to return to the last state. Or better, set everything to default values after you are finished with it (calling glDisableClient for all enabled vertex arrays should be enough).</p> |

I've created sandbox "subscribe" buttons. When I click the button, I'm taken to the sandbox Paypal site, I enter my sandbox buyer information, and the payment gets processed.</p> <p>Everything seems to work fine, but that's where it ends. I'm left on a page that says the payment is complete. Nowhere in this process does Paypal seem to send any kind of request to my specified IPN landing page.</p> <p>At the top of the PHP code where I receive the IPN, I have a simple mail() function, just for testing to let me know the code has been triggered. I know it works because if I just run it directly in the browser, I get the mail. I do not get the mail when I go through the Paypal sandbox transaction.</p> <p>All indications are that I have not set up Paypal correctly so that it knows I want it to send an IPN notification during the transaction.</p> <p>Do I need a particular button (none of them explicitly say "IPN capable" or anything like that, so my default assumption was that any of them would work.)?</p> <p>In my profile I've specified the page to go to for the IPN message, but perhaps there is another setting that also needs to be configured?</p> <hr> <p><em><strong>Update:</em></strong></p> <p>Here is the code for my button.

7,150,906 | 0 | PHP mail() function causing slow page loads <p>I've been writing a number of PHP pages that involve using mail(). For the most part, it works well. However, occasionally (I'd say about 10-20% of the time), the mail() function causes the page to load exceptionally slowly, if at all. </p> <p>I haven't been able to find a similar problem on forums anywere. Just to reiterate, the mail() function works fine and sends mail, but when calling scripts with the mail() function in it, it occasionally causes slow page load times.</p> <p>Here's the important bits of what the pages look like.

12,015,918 | 0 | <p>To represent the character you can use Universal Character Names (UCNs). The character 'ф' has the Unicode value U+0444 and so in C++ you could write it '\u0444' or '\U00000444'. Also if the source code encoding supports this character then you can just write it literally in your source code.</p> <pre><code>// both of these assume that the character can be represented with // a single char in the execution encoding char b = '\u0444'; char a = 'ф'; // this line additionally assumes that the source character encoding supports this character </code></pre> <p>Printing such characters out depends on what you're printing to. If you're printing to a Unix terminal emulator, the terminal emulator is using an encoding that supports this character, and that encoding matches the compiler's execution encoding, then you can do the following:</p> <pre><code>#include <iostream> int main() { std::cout << "Hello, ф or \u0444!\n"; } </code></pre> <p>This program <em>does not</em> require that 'ф' can be represented in a single char. On OS X and most any modern Linux install this will work just fine, because the source, execution, and console encodings will all be UTF-8 (which supports all Unicode characters).</p> <p>Things are harder with Windows and there are different possibilities with different tradeoffs.</p> <p>Probably the best, if you don't need portable code (you'll be using wchar_t, which should really be avoided on every other platform), is to set the mode of the output file handle to take only UTF-16 data.</p> <pre><code>#include <iostream> #include <io.h> #include <fcntl.h> int main() { _setmode(_fileno(stdout), _O_U16TEXT); std::wcout << L"Hello, \u0444!\n"; } </code></pre> <p>Portable code is more difficult.</p> |

36,993,563 | 0 | <p>It's fine to return a reference as long as the object referred to is not destroyed before control leaves the function (<em>i.e.</em>, an automatic local variable or parameter, or a temporary created inside the function).</p> <p>In this case, you are potentially returning a reference to the temporary <code>Foo()</code> in the <em>calling</em> context, which is fine because that temporary is guaranteed to survive until the end of the full-expression containing the call. However, the reference would become dangling after the full-expression, <em>i.e.</em>, the lifetime of the <code>Foo()</code> temporary is not extended, so care must be taken not to access it again after that point.</p> |

856,569 | 0 | <p>My tests show that <code>z-index: 2147483647</code> is the maximum value, tested on FF 3.0.1 for OS X. I discovered a integer overflow bug: if you type <code>z-index: 2147483648</code> (which is 2147483647 + 1) the element just goes behind all other elements. At least the browser doesn't crash.</p> <p>And the lesson to learn is that you should beware of entering too large values for the <code>z-index</code> property because they wrap around.</p> |

8,924,973 | 0 | <p>Many of the answers have mentioned using a static readonly lock.</p> <p>However, you really should try to avoid this static lock. It would be easy to create a deadlock where multiple threads are using the static lock.</p> <p>What you could use instead is one of the .net 4 concurrent collections, these do provide some thread synchronisation on your behalf, so that you do not need to use the locking.</p> <p>Take a look at the <code>System.collections.Concurrent</code> namespace. For this example, you could use the <code>ConcurrentBag<T></code> class.</p> |
