6,289,547 | 0 | <p>Sorry I did not replay earlier. Quickly, I'll would like to present one way of catching this for your consideration. For simplicity, I'll just concentrate on caching your outputs using Output frontend. </p> <p>In you application.ini you can setup your catching as follows: </p> <pre><code>resources.cachemanager.myviewcache.frontend.name = Output resources.cachemanager.myviewcache.frontend.customFrontendNaming = false resources.cachemanager.myviewcache.frontend.options.lifetime = 7200 resources.cachemanager.myviewcache.frontend.options.caching = true resources.cachemanager.myviewcache.frontend.options.automatic_serialization = true resources.cachemanager.myviewcache.backend.name = Apc </code></pre> <p>Note, that I use Apc as a backend. You may use file backend if you don't have or don't want Apc.</p> <p>With this, I would cache your posts and comments separately. For example, in <code>_posts.phtml</code> you could do something similar to the following:</p> <pre><code>// first cache an output related to the body of your post with key being associated // with your post. if (!($this->viewCache()->start('post_' . (string) $this->object->post_id))) { echo $this->object->title; echo $this->object->text; } // now I cache an output of a comments associated with a give post if (!($this->viewCache()->start('post_comments_' . (string) $this->object->post_id))) { echo $this->partialLoop('_comments.phtml',$this->object->getComments()); } </code></pre> <p>In this example, viewCache() view helper is as follows:</p> <pre><code>class My_View_Helper_ViewCache extends Zend_View_Helper_Abstract { /** * * @return Zend_Cache_Frontend_Output */ public function viewCache() { return Zend_Registry::get('outputCache'); } } </code></pre> <p>Whereas I set <code>outputCache</code> into registry in the Bootstrap.php:</p> <pre><code>protected function _initPutChachesIntoRegistry() { $this->bootstrap('cachemanager'); $cacheManager = $this->getResource('cachemanager'); Zend_Registry::set('outputCache', $cacheManager->getCache('myviewcache')); } </code></pre> <p>Notice that caches are associated with keys which in turn relate to a given post and its comments. With this, when you get a new comment, you just reset a cache related to the given post. For example, in an action, you can remove comment cache for a post with $post_id=5 as follows:</p> <pre><code>$this->view->viewCache()->remove('post_comments_' . $post_id); </code></pre> <p>Hope that this will help you or at least give you some ideas how to make it. </p> |

20,627,067 | 0 | <p>Your code isn't compilable. Here is the reasons:</p> <ol> <li>The conditions must be placed into some method</li> <li>The declaration of event handler must be moved out from the condition scope</li> </ol> <p>Here is the workable code:</p> <pre><code>namespace WindowsFormsApplication1 { public partial class Form1 : Form { private int flag; FileSystemWatcher watcher = new FileSystemWatcher(); public Form1() { InitializeComponent(); watcher.Path = @"C:\"; watcher.Filter = "test.txt"; watcher.Changed += watcher_Changed; watcher.EnableRaisingEvents = true; } private void SetFlag() { FileInfo info = new FileInfo("c:\\test.txt"); if (info.Length > 0) flag= 1; } private void CheckFlag() { if(flag==1) { button1.PerformClick(); } } private void button1_Click(object sender, EventArgs e) { //Code for Redirection to New Form } void watcher_Changed(object sender, FileSystemEventArgs e) { SetFlag(); CheckFlag(); } } } </code></pre> <p>And now you can call method <code>SetFlag()</code> to set flag. And use method <code>CheckFlag()</code> to check flag. In this example I use <code>FileSystemWatcher</code> to catch all file changes and call <code>SetFlag()</code> and <code>CheckFlag()</code> inside the handler of event <code>Changed</code></p> <p>Instead of <code>button1.PerformClick()</code> you can use <code>button1_Click(this, EventArgs.Empty)</code></p> |

11,952,033 | 0 | <p>I suppose <a href="http://en.wikipedia.org/wiki/Singleton_pattern" rel="nofollow">Singleton</a> should help you managing it better, so you dont have to pass the pointer around. Practically, <code>mpi_glob</code> does the same, <code>Singleton</code> is just more accustomed way.</p> <p>Alternatively, you can still resort to global variables - they are not bad as such. If you want to emphasize one-time assignment you can declare them <code>const</code> and set them via static initializer like this:</p> <pre><code>const int number_of_tasks = get_preconfigured_number_of_tasks(); </code></pre> <p>If your global variables are used to hold compile time constants, then it is perfectly fine to replace them with <code>enum</code> members or preprocessor defines. Doing so will ease up on compiler, because it can use immediate value in-place without memory access.</p> <hr> <p>Credit goes to Pete Becker for pointing Singleton issues in his comment. If those issues bother you too, then totally different approach can be taken.</p> <p>Remember how Java programs are implemented? There is main class with main method and all program's work runs from inside that main method. Main is still member function, i.e. it can exclusively access some private fields of the main class (they have to be static in case of Java, but this is not the main point here).</p> <p>We can further extend the concept to <a href="http://en.wikipedia.org/wiki/Command_pattern" rel="nofollow">Command</a>-like implementation. The difference with conventional Java is that your main method equivalent is not static and your global variables with values specific to contained program are non-static member variables. All functions that need access to global state data are to be converted into member functions. This is possible, because main method is also member function.</p> <p>This way, I think, you can achieve better encapsulation and data safety.</p> |
1,964,450 | 0 | <p>Here's a more idiomatic and generic approach:</p> <pre><code>template<typename K, typename T> class AVLTree { ... template <typename Comparer> void foo(Comparer cmp) { ... int res = cmp(key1, key2); ... } ... }; </code></pre> <p>Comparer should not be a type that defines a static <code>Compare</code> method. It should be a type which can be called with function call syntax. That allows you to use function pointers of function objects, and it allows you to reuse the comparers already defined in the standard library, or in pretty much any other nontrivial C++ application. It allows you to use lambdas when they're added in C++0x.</p> <p>As for forcing <code>Comparer</code> to behave as expected? The line <code>int res = cmp(key1, key2);</code> already ensures that. If you try to pass a type that can't be called in this way, you get a compile error.</p> <p>The same was the case in your original code. If you passed a type that didn't have a static <code>Compare</code> method, you'd get a compile error. So your original code already solved the problem.</p> |

My goal is to get a list of flickr images based on location and take the image IDs returned from the request and pass them into another request to get more information for each photo to be displayed in the results. Here is what I have but I can't seem to get the correct value returned from my second search function. Although this seems like a long question, I really just want to know how to get the correct value in my second function so I can assign it to my results. </p> <p>This is in my services.js</p> <pre><code>//flickr location search APIRequest.fkrSearch = function(lat, lon, rad){ fkrAPI = $resource('https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=5956ffe850b325e0b121525800af5b31&lat='+lat+'&lon='+lon+'&radius=5km&format=json&nojsoncallback=1', { dataType: 'jsonp', jsonp: 'jsoncallback' }); return fkrAPI.get().$promise.then(function (data){ console.log(data); return data; }); }; </code></pre> <p>Here is my request within my controller.</p> <pre><code>$scope.resultPosts = []; //global variable to hold results if ($scope.locationSearch.dataSource.fkr){ $scope.fkrLoading = true; console.log('search Flickr'); OSINTAPIRequest.fkrSearch($scope.lat, $scope.lng, $scope.radius).then(function(data){ if (data.error){ toastr.error(data.error.error_msg, 'Flickr Error['+data.error.error_code+']'); } else { if (data.photos.photo.length > 0){ var fkrAppend = 0; for(var i=0; i < data.photos.photo.length; i++){ fkrAppend++; var fkrImageId = data.photos.photo[i].id; $scope.resultPosts.push({ SourcePostID: data.photos.photo[i].id, Timestamp: '', PostLatitude: $scope.fkrGetLatLng(data.photos.photo[i].id), PostLongitude: $scope.fkrGetLatLng(data.photos.photo[i].id), PostMedia: 'https://farm'+data.photos.photo[i].farm+'.staticflickr.com/'+data.photos.photo[i].server+'/'+data.photos.photo[i].id+'_'+data.photos.photo[i].secret+'.jpg', PostType: 'image', PostAvatar: 'https://pingendo.github.io/pingendo-bootstrap/assets/user_placeholder.png', PostMarker: 'assets/img/fkrMarker.png', DataSource: 'flickr', Display:$scope.resultFilter.fkr }); } </code></pre> <p>This function returns a list of the image Ids for the photos geotagged in the give lat/long, but does not return the actual location data in the results for me to pass to the results and plot the point on the map. So you'll see that in my resultsPosts.push I'm trying to pass the returned image Id to the fkrGetLatLng function with this line <code>(PostLatitude: $scope.fkrGetLatLng(data.photos.photo[i].id))</code>... the function looks like this. </p> <pre><code>$scope.fkrGetLatLng = function (fkrImageId){ OSINTAPIRequest.fkrGetLatLong(fkrImageId).then(function(data){ var fkrLat = data.photo.location.latitude; var fkrLng = data.photo.location.latitude; //console.log (fkrLat+','+fkrLng); return fkrLat; }); } </code></pre> <p>And this is the request in the services JS. I'm getting the correct data back for each request, but it's not assigning the PostLatitude the correct value (or any value at all).</p> <pre><code> //flickr location search - get lat long APIRequest.fkrGetLatLong = function(fkrImageId){ fkrAPI = $resource('https://api.flickr.com/services/rest/?method=flickr.photos.geo.getLocation&api_key=5956ffe850b325e0b121525800af5b31&photo_id='+fkrImageId+'&format=json&nojsoncallback=1', { dataType: 'jsonp', jsonp: 'jsoncallback' }); return fkrAPI.get().$promise.then(function (data){ //console.log(data); return data; }); }; </code></pre> |

27,654,734 | 0 | <p>I had a similar issue. It was not really an issue with Gmail or with PHP. The issue, in my case, was that when PHP generated the email message from my PHP source file, like the one above, it interpreted the end of lines in some way that Gmail did not like, perhaps it sent a LF instead of CRLF, some thing like that. I did not look at the details. What I know is that, given that the default on my emails was CRLF for an end of line, I wrote explicitly all end of lines using <code><?php echo "\r\n"; ?></code>, instead of relying on empty lines in the file and then Gmail interpreted correctly the message. It is likely that the issue was specific to the editor I used to write the PHP source file. In my case it was Notepad++. Perhaps it was not configured properly. It does not matter, now, just to be on the safe side, I always explicitly enter the end of lines in my email messages, at the least for the part that must be understood by MTAs and MUAs, the Content-Type, the boundary, etc. </p> |

31,252,223 | 0 | <p>First, <code>open()</code> is used for files. What you want is <code>opendir()</code>. Next, when you use <code>opendir(), readdir()</code>, it doesn't keep the path information, so you need to prepend it to the files you're renaming. Third, it's more common to use lexical handles as opposed to bare names. Lastly, always <code>use strict;</code> and <code>use warnings;</code> which would have pointed you directly to the problem.</p> <p>Here's a slightly updated version of your code:</p> <pre><code>#!/usr/bin/perl use warnings; use strict; my $dir = "/path/to/dir"; opendir(my $dh, $dir) or die $!; while ( my $file = readdir($dh) ) { next if ( $file =~ m/(^\.)/ ); next unless -f $file; if ( $file !~ m/csv$/ ) { print "*** renaming file $file ***\n"; my $oldfile = $file; $file =~ s/\..*$/.csv/; print "$oldfile => $file\n"; rename "$dir/$oldfile", "$dir/$file"; print "Done\n"; } } </code></pre> <p>Another way to do this is use a file glob (per suggestion by Sobrique):</p> <pre><code>#!/usr/bin/perl use warnings; use strict; my @files = </path/to/dir/*>; for my $file (@files){ next unless -f $file; if ($file !~ /\.csv$/){ print "*** renaming file $file ***\n"; my $oldfile = $file; $file =~ s/\..*$/.csv/; print "$oldfile => $file\n"; rename $oldfile, $file; print "Done!\n"; } } </code></pre> |

32,260,332 | 1 | Defining a constructor for ponyorm's Entities results in TypeError <p>i just wanted to try out the pony orm mapper for a small personal web application. Everything works fine except for defining a custom constructor for an entity.</p> <p>In the following code i created a simple entity with a string field <code>name</code> and defined a constructor which does nothing but redirect the arguments to the parent constructor (in my real app i change some of the arguments bevor passing them to the parent constructor). After that i create one <code>User</code> and print its name.</p> <pre><code>from pony.orm import Database, Required, db_session, commit db = Database("sqlite", ":memory:", create_db=True) class User(db.Entity): def __init__(self, *args, **kwargs): super(User, self).__init__(*args, **kwargs) name = Required(str) db.generate_mapping(create_tables=True) with db_session: u = User(name="Admin") commit() print(u, u.name) </code></pre> <p>The error message is <code>TypeError: object.__init__() takes no parameters</code> in the same line as the <code>super()</code>call. It looks like the keyword arguments are sent to <code>object</code> instead of <code>db.Entity</code>. When i remove the constructor everything works</p> <p>So why doesn't it work. Shouldn't a constructor like the one in my example just always work (and do nothing of course)? Is there something in ponyorm that prevents it from working or am i missing something here?</p> <p>For completeness sake my entity definition actually looks like this</p> <pre><code>class User(db.Entity): def __init__(self, *args, **kwargs): if "password" not in kwargs: raise ValueError("password is required") kwargs["password"] = werkzeug.security.generate_password_hash(kwargs["password"]) super().__init__(*args, **kwargs) name = Required(str) password = Required(str) </code></pre> <p>It produces the same results.</p> <p>Also in the official documentation it says that method creation in entities is allowed at least. <a href="http://doc.ponyorm.com/entities.html#adding-custom-methods-to-entities" rel="nofollow">http://doc.ponyorm.com/entities.html#adding-custom-methods-to-entities</a> .

3,451,451 | 0 | Why do people spend so much time searching for, and hacking around with, "free" toolsets when superior pay ones are available? <p><strong>Clarification:</strong> I'm referring to companies that pay developers, professionally. I understand why a "hobby" or "for fun" developer wouldn't want to (or couldn't afford) a fully-features pay tool, and may prefer to tinker. I'm talking about situations where a deadline is bearing down on a developer/company and development time is diverted away from the goal in pursuit of a "Free" tool to accomplish what a pay one is available to do.</p> <hr> <p>I've noticed a number of Stack Overflow questions recently (they're not new, I've just recently taken notice) where people are searching for free alternatives to popular development tools for things like <a href="http://en.wikipedia.org/wiki/Application_lifecycle_management" rel="nofollow noreferrer">ALM</a>, database comparison, and other functions for which there's a trivially costly pay alternative. The "Free" tag on Stack Overflow has 350 questions, and it doesn't take long to see dozens of examples of "Is there a FREE tool to do X?" followed by discussions that must have taken the asker hours to research and participate in.</p> <p>It's not just about paying less - I'm often amazed at the hoops that some developers (or, perhaps more accurately, their companies) will go through to avoid paying for something - in some cases, a pay solution will be avoided in favor of a poorly documented, buggy, feature-incomplete open-source solution that results in dozens of hours of work that could have been avoided.</p> <p>I understand the most obvious reasons:</p> <ul> <li>Company is short on cash</li> <li>Don't pay for something when a (functionally-comparable) free alternative is available</li> <li>"Hobby" developers don't have the cash to spare, and since they're just learning, it doesn't make sense to pay for a toolset they're only tinkering with</li> </ul> <p>However, I think the "short on cash" reasoning is completely bogus - as a developer not long out of college, I made about $50K annually, or $200/day (meaning my company probably paid close to $300/day to have me in my chair, all considered). When you compare that price to a $300 tool, the obvious answer is "if it's going to waste more than a day of your time, you should buy it instead and get back to work". However, that's not what I observe - people seem willing to kill dozens of hours to avoid paying for something that only costs $50.</p> <p>Help me understand - as a developer myself of tools I'd like to one day sell, I want to understand the mentality. Have I been spoiled by working at a company that's not afraid to spend? Is there an ingrained reason developers (or their companies) don't want to spend money? Can people not accurately estimate the costs of "Free" tools in terms of lost productivity?</p> <hr> <p>I'm not referring to instances where a great free alternative is available. For example, <a href="http://stackoverflow.com/questions/662956/most-useful-free-net-libraries">any of these tools</a> is a great example of something you shouldn't pay for. However, let's say one of those lacks a key feature you need, and which a pay version of the same library provides - people seem to lean towards hacking around with the free version to add the needed functionality (or scaffold in the needed functionality) instead of ditching the free tool in favor of the pay (and feature-complete) version. I'm not saying that's the wrong choice, but it's just a choice I want to understand the reasoning to. The important point is that I'd like to - my intent is not to be argumentative.</p> |

36,883,973 | 0 | html5 multiple file upload with spring mvc 4 and spring boot <p>I'm trying to upload multiple files using spring mvc 4, spring boot and thymeleaf as template engine, but i'm not able to access the uploaded files, the files are dealt with as one multipart file with content type application/octet-stream. here's my front-end code:</p> <pre><code> <form name="offer-form" th:action="@{/submit-property}" method="POST" enctype="multipart/form-data"> <!-- .. other inputs .. --> <div class="col-xs-12 margin-top-60"> <input id="file-upload"name="files[]" type="file" multiple="multiple"/> </div> <div class="col-xs-12"> <div class="center-button-cont margin-top-60"> <button type="submit" class="button-primary button-shadow"> <span>submit property</span> <div class="button-triangle"></div> <div class="button-triangle2"></div> <div class="button-icon"><i class="fa fa-lg fa-home"></i></div> </button> </div> </div> </form> </code></pre> <p>And the controller code:</p> <pre><code>import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import org.apache.tomcat.util.http.fileupload.IOUtils; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.core.io.FileSystemResource; import org.springframework.core.io.Resource; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.ModelAttribute; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.multipart.MultipartFile; import com.aq.domain.Property; import com.aq.service.AddPropertyFormDataInitializerService; @Controller public class PorpertySubmissionController { public static final Resource PICTURES_DIR = new FileSystemResource("./uploadedPictures"); //some unrelated code @RequestMapping(value="/submit-property", method=RequestMethod.GET) public String getSubmitPropertyForm(Model model) { model.addAttribute("property", new Property()); return "submit-property"; } @RequestMapping(value="/submit-property", method=RequestMethod.POST) public String submitProperty ( @ModelAttribute(value="property") Property property, @RequestParam("files[]") MultipartFile[] uploadedImages ) { //some unrelated code if(uploadedImages != null && uploadedImages.length > 0) { System.out.println("uploadedImages length: " + uploadedImages.length); for(MultipartFile imageFile : uploadedImages) { try { copyFileToPictures(imageFile); System.out.println("copied File: " + imageFile.getOriginalFilename() + " successfully."); } catch (IOException e) { System.err.println(e.getMessage()); e.printStackTrace(); } } } else { System.out.println("no images were uploaded"); } return "redirect:/submit-property"; } private Resource copyFileToPictures(MultipartFile file) throws IOException { System.out.println("File Original Name: " + file.getOriginalFilename()); System.out.println("File Name: " + file.getName()); System.out.println("File size: " + file.getSize()); System.out.println("File Content type: " + file.getContentType()); String fileExtension = getFileExtension(file.getOriginalFilename()); File tempFile = File.createTempFile("pic", fileExtension, PICTURES_DIR.getFile()); try (InputStream in = file.getInputStream(); OutputStream out = new FileOutputStream(tempFile)) { IOUtils.copy(in, out); } return new FileSystemResource(tempFile); } private static String getFileExtension(String name) { return name.substring(name.lastIndexOf(".")); } } </code></pre> <p>the output of the sysout:</p> <p>uploadedImages length: 1 (even though i upload multiple files)</p> <p>File Original Name (using getOriginalFileName): </p> <p>File Name (using getName): files[]</p> <p>File size: 0</p> <p>File Content type: application/octet-stream</p> <p>and then an exception when subsctring is called on the empty original file name.</p> <p>I tried to add commons file upload to my POM and configured CommonsMultipartResolver bean, but then it always prints that there are no uploaded images (which means it's null or length=0)</p> |
16,395,726 | 0 | <p>Unlike what everyone else tells you, this is unrelated to Windows and <code>File.separator</code>.</p> <p><code>String DIR_PATH = "a/b/c/"</code> is just a String, neither Java nor the compiler make any attempt to understand what it could mean, so you get the same value both on Windows and Linux.</p> <p>Also note that <code>/</code> works as a file separator both on Unix and Windows, so this isn't an issue either. When necessary, Java will convert <code>/</code> to <code>\</code>.</p> <p><code>File DIR_FILE = new File(DIR_PATH);</code> is a constant but <code>new File()</code> is still executed by the VM at runtime when the class is loaded. So the path is <strong>not</strong> converted to Windows format while the <em>compiler</em> generates byte code.</p> <p>So the problem you describe must be elsewhere or an important part of the code example you posted was changed when you simplified it for the question. My guess is that someone put a Windows-style path into the code elsewhere or maybe the config and you overlooked this.</p> <p>That said, a safe way to build paths is to use <code>File(File, String)</code>:</p> <pre><code>File DIR_PATH = new File( "a", new File( "b", "c" ) ); </code></pre> <p>This will always build a path that works, no matter what the file separator is. If you must, you can use</p> <pre><code>File DIR_PATH = "a" + File.separator + "b" + File.separator + "c"; </code></pre> <p>but that can fail for more complex examples and it's more text to read.</p> |
