• Drupal: FileFields... internal server error

  - by Patrick

  hi, I've moved my drupal installation to new server and the website works. HOwever I get an "internal server error" for each file field in my nodes. In other words, images and videos are not loaded. In Firebug, Net Tab I can see they cannot be retrieved from the server because of "internal server error". The only thing I changed with respect to the previous installation is commenting the following 2 lines in .htaccess # Don't show directory listings for URLs which map to a directory. #Options -Indexes # Follow symbolic links in this directory. #Options +FollowSymLinks Is this the issue ? How can I solve this ? thanks

• How do I add a function to an element via jQuery?

  - by Chad Johnson

  I want to do something like this: $('.dynamicHtmlForm').validate = function() { return true; } $('.dynamicHtmlForm .saveButton').click(function() { if (!$(this).closest('.dynamicHtmlForm').validate()) { return false; } return true; }); And then when I have a form of class dynamicHtmlForm, I want to be able to provide a custom validate() function: $('#myDynamicHtmlForm').validate = function() { // do some validation if (there are errors) { return false; } return true; } But I get this when I do this: $(this).closest(".dynamicHtmlForm").validate is not a function Is what I've described even possible? If so, what am I doing wrong?

• How can I find out how much memory an object (rather the instance of an object) of a C++ class consu

  - by Shadow

  Hi, I am developing a Graph-class, based on boost-graph-library. A Graph-object contains a boost-graph, so to say an adjacency_list, and a map. When monitoring the total memory usage of my program, it consumes quite a lot (checked with pmap). Now, I would like to know, how much of the memory is exactly consumed by a filled object of this Graph-class? With filled I mean when the adjacency_list is full of vertices and edges. I found out, that using sizeof() doesn't bring me far. Using valgrind is also not an alternative as there is quite some memory allocation done previously and this makes the usage of valgrind impractical for this purpose. I'm also not interested in what other parts of the program cost in memory, I want to focus on one single object. Thank you.

• How to avoid recursion in Java SecurityManager checkConnect?

  - by Zilupe

  I'm trying to take control of a Java code base that does lots of un-documented things. I'm using a custom SecurityManager to check permission requests. Specifically, my code is checking SocketPermission checks -- checkConnect. checkConnect is called when the application tries to resolve a host name to IP address and to connect to a specific IP address. The problem is that I don't know how to properly call host name resolution (InetAddress.getAddressByName) without falling into infinite recursion, because normally checkConnect is called even when I resolve the name from inside the SecurityManager.checkConnect. I have read on the web that I have to call the address resolution from a doPrivileged block, but no idea how. P.S. Is this possible without writing any policy files?

• Capistrano update causes C: to be placed in the current directory (cygwin)

  - by user321775

  When I run cap deploy:update in a directory on my local machine (via cygwin), "C:" magically appears in the directory. Sure enough, I can cd to it and it's my windows C: drive. Now I'm afraid to delete it, but I definitely don't want it in this directory (a rails project under /home/username/blah/blah). Here's my config/deploy.rb file. custom options set :application, "xyz.com" set :repository, "ssh://[email protected]:yyyy/home/git/xxx" set :user, "myname" set :runner, user set :use_sudo, false server "xxx.xxx.xxx.xxx:yyyy", :app, :web, :db, :primary = true deploy to set :deploy_to, "/home/myname/public_html/xyz" repository set :scm, :git set :deploy_via, :copy ssh options default_run_options[:pty] = true ssh_options[:paranoid] = false ssh_options[:port] = yyyy start passenger namespace :deploy do task :start do ; end task :stop do ; end task :restart, :roles = :app, :except = { :no_release = true } do run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}" end end Anyone see the problem? And does anyone know a safe way of getting rid of the C: drives that have already shown up (this has happened in a few directories)?

• Mysql search design

  - by neil

  I'm designing a mysql database, and i'd like some input on an efficient way to store blog/article data for searching. Right now, I've made a separate column that stores the content to be searched - no duplicate words, no words shorter than four letters, and no words that are too common. So, essentially, it's a list of keywords from the original article. Also searched would be a list of tags, and the title field. I'm not quite sure how mysql indexes fulltext columns, so would storing the data like that be ineffective, or redundant somehow? A lot of the articles are on the same topic, so would the score be hurt by so many of the rows having similar keywords? Also, for this project, solutions like sphinx, lucene or google custom seach can't be used -- only php & mysql. Thanks!

• how to create a auto-incremented attribute in xcode managed object model

  - by Mausimo

  Hey, what i want to do is to make a int that will be the ID of the entity and auto increment itself whenever a new entity is added (just like a SQL identity property). Is this possible? i tried using indexed (checked on attribute) however there is no description to what indexed even does. EDIT: I am adding annotations to a map, when you click the pin the annotationview with a chevron shows up. Now when you click this button i would like to load an associated picture. However the only way i know how to link the picture to this button is to give the picture a unique id, and then set the button.tag to this id and then load based on the button.tag.

• How to synchronize two (or n) replication processes for MS SQL databases?

  - by Yauheni Sivukha

  There are two master databases and two read-only copies updated by standard transactional replication. It is needed to map some entity from both read-only databases, lets say that A databases contains orders and B databases contains lines. The problem is that replication to one database can lag behind replication of second database, and at the moment of mapping R-databases will have inconsistent data. For example. We stored 2 orders with lines at 19:00 and 19:03. Mapping process started at 19:05, but to the moment of mapping A database replication processed all changes up to 19:03, but B database replication processed only changes up to 19:00. After mapping we will have order entity with order as of 19:03 and lines as of 19:00. The troubles are guaranteed:) In my particular case both databases have temporal model, so it is possible to fetch data for every time slice, but the problem is to identify time of latest replication. Question: How to synchronize replication processes for several databases to avoid situation described above?

• Looking for a new PHP website framework

  - by Glycerine

  I built many a website, and my own 'custom' framework is just a general box of scripts cobbled together with loose ideas. I would love to progress to a framework which allows me to pass it onto the client for freedom. Someone suggested using wordpress but I'm not sure how general this can be. A current site I need to build is a fancy kitchen company, price lists, flash gallery (with backend driven pics) and well designed home. How could I bend the the will of wordpress? Alternatively, does anyone have a suggestion for an alternative. Thanks in advance guys -

• Need new method for linking to native mapping from mobile web app

  - by Carter

  My mobile web apps use a map button which automatically starts the mapping features of Android and iPhone by simply linking to http://maps.google.com/maps?q=New+York. iOs 6 comes out, the links stop working, because Apple wants us to use "maps.APPLE.com". Turns out ANYTHING you send to "maps.apple.com" gets forwarded to "maps.google.com". So now I have to specially detect iOs 6 and swap out links just so Apple can forward everything back to Google anyway. Is there a clean way to open the device/native mapping app from a mobile web app that works on Android, iOs 6, and iOs pre-6, since iOs 6 nerfed it? Recently updated documentation on Apple dev site... http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/MapLinks.html#//apple_ref/doc/uid/TP40007894-SW1 Both these links go to the same place http://maps.google.com/maps?q=New+York http://maps.apple.com/maps?q=New+York

• Action method expected parameter named Id and nothing otherwise

  - by codingbiz

  The Error The parameters dictionary contains a null entry for parameter 'UserId' of non-nullable type 'System.Int64' for method 'System.Web.Mvc.ActionResult Predict(Int64)' in 'sportingbiz.Controllers.PredictionController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters This does not work. Throws the error mentioned above http://mysite/User/Profile/15 This works http://mysite/User/Profile/?UserID=15 The Controller Action public ActionResult Profile(long UserID) { } When I changed the parameter name to Id it works. I think it's because Id was specified in the route collection (Global.asax). Is it possible to tell MVC that UserId should map to Id without changing it in the Global.asax

• MVVM Binding To Property == Null

  - by LnDCobra

  I want to show some elements when a property is not null. What is the best way of achieving this? The following is my ViewModel: class ViewModel : ViewModelBase { public Trade Trade { get { return _trade; } set { SetField(ref _trade, value, () => Trade); } } private Trade _trade; } ViewModelBase inherits INotifyPropertyChanged and contains SetField() The Following is the Trade class: public class Trade : INotifyPropertyChaged { public virtual Company Company { get { return _company; } set { SetField(ref _company, value, () => Company); } } private Company _company; ...... } This is part of my View.xaml <GroupBox Visibility="{Binding Path=Trade.Company, Converter={StaticResource boolToVisConverter}}" /> I would like this groupbox to show only if Trade.Company is not null (so when a user selects a company). Would I need to create a custom converter to check for null and return the correct visibility or is there one in .NET?

• What is the recommended way to split messages in send pipelines?

  - by ToxicAvenger

  I need to split a bizTalk message in the send pipeline. This is easy with disassemblers in receive pipelines, but doesn't work in send pipelines (makes sense). So what is the recommended way to do it? The only easy way to do it is to write the outbound message to file, then reprocess it using a receive pipeline with a disassembler, and then send the generated messages through a outbound pipeline. Honestly, I don't need the additional roundtrip through the message box, but I don't want to create a custom send adapter. Any other suggestions? Any easy way to save messages with multiple parts using the ootb file adapter?

• Compute hex color code for an arbitrary string

• Spring FactoryBean and scopes working together

  - by TTar

  I'd like to use FactoryBeans and scopes together. Specifically, I'd like the object created and returned by a FactoryBean to be placed into a specified (perhaps custom) scope. The issue is that doing the following: <bean class="x.y.z.TestFactoryBean" scope="test" /> Results in the FactoryBean itself being scoped, and has somewhat unpredictable behaviour on the object created by the factory. I understand why this is; the factory itself is a first-class spring-managed bean, and has its own lifecycle. However, I can't find a way to specify that the object returned from the factory should itself be scoped. On the other hand, this does exactly what I want (as long as TestFactoryBean does NOT implement the FactoryBean interface): <bean class="x.y.z.TestFactoryBean" name="testFactory"> <bean class="x.y.z.TestBean" factory-bean="testFactory" factory-method="getObject" scope="test" /> So the real question is, how can I make Spring behave like it does for the 2nd example above, but using real FactoryBeans?

• How to enable an AdventureWorks database in a web application?

  - by salvationishere

  I am developing a C#/SQL ASP.NET web application in VS 2008. I want the users to be able to select an Adventureworks table and then an input file. The user is then able to map columns from the file with the selected table. This app works fine now in VS. But when I Browse in IIS, it doesn't show any of the tables. I think this is because currently Adventureworks connection string is integrated security (Windows authentication). If I want users to be able to select a table, do I have to change connection to SQL Server authentication? And if so, is the only way to do this to reinstall SQL Server? Or can I just reinstall Adventureworks? And if I reinstall SQL Server, do I need to reinstall VS also for this to work? This could be painful...

• ConcurentModificationException in Java HashMap

  - by Bear

  Suppose I have two methods in my classes, writeToMap() and processKey() and both methods are called by multiple threads. writeToMap is a method to write something in hashmap and processKey() is used to do sth based on the keySet of HashMap. Inside processKey, I first copy the originalMap before getting the key set. new HashMap<String, Map<String,String>(originalMap).get("xx").keySet(); But I am still getting ConcurrentModificationException even though I always copy the hashmap. Whats the problem?

• Passing around objects to network packet handlers ?

  - by xeross

  Hey, I've been writing a networking server for a while now in C++ and have come to the stage to start looking for a way to properly and easily handle all packets. I am so far that I can figure out what kind of packet it is, but now I need to figure out how to get the needed data to the handler functions. I had the following in mind: Have a map of function pointers with the opcode as key and the function pointer as value Have all these functions have 2 arguments, packet and ObjectAccessor ObjectAccessor class contains various functions to fetch various items such as users and alike Perhaps pass the user's guid too so we can fetch it from the objectaccessor I'd like to know the various implementations others have come up with, so please comment on this idea and reply with your own implementations. Thanks, Xeross

• Ruby on Rails ActiveScaffold: Showing {{model}} instead of model name?

  - by AnExtremelySmellyPerson

  Hi there, I'm using ActiveScaffold with Ruby on Rails and I'm loving it, however there is one weird thing. Whenever I hit "Edit" or "Create New" in my webapp's ActiveScaffold, it says "Create {{model}}" or "Update {{model}}" in the webapp rather than using the model's name. Why is this? I have an ads_controller.rb that includes this: active_scaffold :ad do |config| config.label = "Ads" config.columns = [:name, :description, :imageUrl, :linkUrl, :apps, :created_at, :updated_at] config.update.columns = [:name, :description, :imageUrl, :linkUrl, :apps] config.create.columns = config.update.columns list.sorting = {:created_at => 'DESC'} columns[:imageUrl].label = "Image URL" columns[:linkUrl].label = "Link URL" end And my routes.rb includes this: map.namespace :admin do |admin| admin.root :controller => 'admin_home', :action => 'index' admin.resources :ads, :active_scaffold => true end Any thoughts on why I'm seeing "Create {{model}}" instead of "Create ad" ?

• Should the name of my classes begin with 'Q' in Qt?

  - by Venemo

  Hello Everyone, When I first started working with Qt, it was extremely annoying that every class has a name beginning with 'Q', but now I've got used to it. I'm using Qt Creator, and it highlights code quite well. However, it only highlights class names beginning with 'Q'. And it highlights everything beginning with 'Q' even if there is no such type. It doesn't highlight custom class names. That makes me wonder, should I also begin all my class names with 'Q'? Or at least the reusable ones? (I mean, those that I put in a class library, or reuse in another app.) I've seen several places where they named their classes this way. Is it a good thing? I found this page about Qt's naming conventions, but it doesn't deal with this question. Also, I don't understand why Qt doesn't use namespaces.

• How to show raw_id value of a ManyToMany relation in the Django admin?

Unfortunatey, it doesn't work with ManyToMany. I've checked the code and I think that it is the normal behavior. However I would like to know if someone has an easy tip to change this behavior? Thanks in advance Update: I've tried to subclass the ManyToManyRawIdWidget but I don't know how to say that the raw_id_fields should use my custom widget. formfield_overrides doesn't seem to work with raw_id fields

• How to link to a folder in document library from sharepoint list item?

  - by kyrisu

  Hi, Background: I have an items on the sharepoint list. I also have a corresponding folder in a document library that contains documents about this item. I want to be able to get to this folder straight from the item properties. I have tried to create a lookup column containing folder ID, but that doesn't help cause folder is not a type and it just doesn't work. Other solution would be to create link column but if I will create it staticly - after creating alternative mapping (and getting to the page from the internet for example) it won't work. (so solution posted here won't work for me). I want to create this link from sharepoint workflow. I have a custom action that can return any info about the folder I want (ID, URL etc). Question: How to link from sharepoint list item to a folder in document library?
