• WCF Security Transport Security Questions

  - by shyneman

  I'm writing a set of WCF services that rely on transport security with Windows Authentication using the trusted subsystem model. However, I want to perform authorization based on the original client user that initiated the request (e.g. a user from a website with a username/password). I'm planning to achieve this by adding the original user's credentials in the header before the client sends the message and then the service will use the supplied credentials to authorize the user. So I have a few questions about this implementation: 1) using transport security with windows auth, I do NOT need to worry about again encrypting the passed credentials to ensure the validity... WCF automatically takes care of this - is this correct? 2) how does this implementation prevent a malicious service, running under some windows account within the domain, to send a message tagged with spoofed credentials. for e.g. a malicious service replaces the credentials with an Admin user to do something bad? Thanks for any help.

• Strange exception when connecting to a WCF service via a proxy server

  - by Slauma

  The exception "This operation is not supported for a relative URI." occurs in the following situation: I have a WCF service: [ServiceContract(ProtectionLevel=ProtectionLevel.None)] public interface IMyService { [OperationContract] [FaultContract(typeof(MyFault))] List<MyDto> MyOperation(int param); // other operations } public class MyService : IMyService { public List<MyDto> MyOperation(int param) { // Do the business stuff and return a list of MyDto } // other implementations } MyFault and MyDto are two very simple classes marked with [DataContract] attribute and each only having three [DataMember] of type string, int and int?. This service is hosted in IIS 7.0 on a Win 2008 Server along with an ASP.NET application. I am using an SVC file MyService.svc which is located directly in the root of the web site. The service configuration in web.config is the following: <system.serviceModel> <services> <service name="MyServiceLib.MyService"> <endpoint address="" binding="wsHttpBinding" bindingConfiguration="wsHttpBindingConfig" contract="MyServiceLib.IMyService" /> </service> </services> <bindings> <wsHttpBinding> <binding name="wsHttpBindingConfig"> <security mode="None"> <transport clientCredentialType="None" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior> <serviceMetadata httpGetEnabled="false"/> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> This seems to work so far as I can enter the address http://www.domain.com/MyService.svc in a browser and get the "This is a Windows Communication Foundation Service"-Welcome page. One of the clients consuming the service is a console application: MyServiceClient aChannel = new MyServiceClient("WSHttpBinding_IMyService"); List<MyDto> aMyDtoList = aChannel.MyOperation(1); It has the following configuration: <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_IMyService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="true" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="false" proxyAddress="10.20.30.40:8080" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="None"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://www.domain.com/MyService.svc" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IMyService" contract="MyService.IMyService" name="WSHttpBinding_IMyService" /> </client> </system.serviceModel> When I run this application at a production server at a customer site calling aChannel.MyOperation(1) throws the following exception: This operation is not supported for a relative URI. When I run this client application on my development PC with exactly the same config, with the exception that I remove proxyAddress="10.20.30.40:8080" from the bindings the operation works without problems. Now I really don't know what specifying a proxy server address might have to do with absolute or relative URIs. The use of the proxy server or not is the only difference I can see when running the client on the production or on the development machine. Does someone have an idea what this exception might mean in this context and how possibly to solve the problem? Thank you in advance for help!

• How to handle Booleans/CheckBoxes in ASP.NET MVC 2 with DataAnnotations?

  - by asp_net

  I've got a view model like this: public class SignUpViewModel { [Required(ErrorMessage = "Bitte lesen und akzeptieren Sie die AGB.")] [DisplayName("Ich habe die AGB gelesen und akzeptiere diese.")] public bool AgreesWithTerms { get; set; } } The view markup code: <%= Html.CheckBoxFor(m => m.AgreesWithTerms) %> <%= Html.LabelFor(m => m.AgreesWithTerms)%> The result: No validation is executed. That's okay so far because bool is a value type and never null. But even if I make AgreesWithTerms nullable it won't work because the compiler shouts "Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions." So, what's the correct way to handle this?

• django admin: Add a "remove file" field for Image- or FileFields

  - by w-

  I was hunting around the net for a way to easily allow users to blank out imagefield/filefields they have set in the admin. I found this http://www.djangosnippets.org/snippets/894/ What was really interesting to me here was the code posted in the comment by rfugger remove_the_file = forms.BooleanField(required=False) def save(self, *args, **kwargs): object = super(self.__class__, self).save(*args, **kwargs) if self.cleaned_data.get('remove_the_file'): object.the_file = '' return object When i try to use this in my own form I basically added this to my admin.py which already had a BlahAdmin class BlahModelForm(forms.ModelForm): class Meta: model = Blah remove_img01 = forms.BooleanField(required=False) def save(self, *args, **kwargs): object = super(self.__class__, self).save(*args, **kwargs) if self.cleaned_data.get('remove_img01'): object.img01 = '' return object when i run it I get this error maximum recursion depth exceeded while calling a Python object at this line object = super(self.__class__, self).save(*args, **kwargs) When i think about it for a bit, it seems obvious that it is just infinitely calling itself causing the error. My problem is i can't figure out what is the correct way i should be doing this. Any suggestions? thanks

• Entity Framework - SaveChanges with GUID as EntityKey

  - by MissingLinq

  I have a SQL Server 2008 database table that uses uniqueidentifier as a primary key. On inserts, the key is generated on the database side using the newid() function. This works fine with ADO.NET. But when I set up this table as an entity in an Entity Framework 4 model, there's a problem. I am able to query the entity just fine, but when creating a new entity and invoking SaveChanges() on the context, the generated uniqueidentifier on the database is all zeros. I understand there was an issue with EF v1 where this scenario did not work, requiring creating the GUID on the client prior to calling SaveChanges. However, I had read in many places that they were planning to fix this in EF 4. My question -- is this scenario (DB-side generation of uniqueidentifier) still not supported in EF4? Are we still stuck with generating the GUID on the client?

• Single Sign On with Forms Authentication

  - by Christo Fur

  I am trying to set up Single sign on for 2 websites that reside on the same domain e.g. http://mydomain (top level site that contains a forms-auth login page) http://mydomain/admin (seperately developed website residing in a Virtual Application within the parent website) Have read a few articles on Single Sign on e.g. http://www.codeproject.com/KB/aspnet/SingleSignon.aspx And they seem to suggest it is just a case of having the same machinekey section in each web.config so that the cookie encryprion and decryption is the same for each application I have set this up and I never get prompted for credentials in the sub-website (the virtual application) I always get prompted in the parent site. In addition to having the same machinekey I've also tried adding the same <authentication> and <authorisation> elements Any idea what I could be missing?

• Why aren't we programming on the GPU???

  - by Chris

  So I finally took the time to learn CUDA and get it installed and configured on my computer and I have to say, I'm quite impressed! Here's how it does rendering the Mandelbrot set at 1280 x 678 pixels on my home PC with a Q6600 and a GeForce 8800GTS (max of 1000 iterations): Maxing out all 4 CPU cores with OpenMP: 2.23 fps Running the same algorithm on my GPU: 104.7 fps And here's how fast I got it to render the whole set at 8192 x 8192 with a max of 1000 iterations: Serial implemetation on my home PC: 81.2 seconds All 4 CPU cores on my home PC (OpenMP): 24.5 seconds 32 processors on my school's super computer (MPI with master-worker): 1.92 seconds My home GPU (CUDA): 0.310 seconds 4 GPUs on my school's super computer (CUDA with static domain decomposition): 0.0547 seconds So here's my question - if we can get such huge speedups by programming the GPU instead of the CPU, why is nobody doing it??? I can think of so many things we could speed up like this, and yet I don't know of many commercial apps that are actually doing it. Also, what kinds of other speedups have you seen by offloading your computations to the GPU?

• Consuming "Event Tracing for Windows" events

  - by Paul Baker

  An answer to this question has led me to look into using "Event Tracing for Windows" for our tracing needs. I have come across NTrace, which seems to be a good way to produce ETW events from C# code (using the XP-compatible "classic provider" model). However, I am unable to find an easy way to consume these events - to see them in real-time and/or log them to a file. The only way I have found is that described in the NTrace documentation: using a tool which is only available as part of the Windows DDK. In the case of a complex problem in the field, we may need to ask the user to produce a file containing a trace. We can't ask users to download the DDK or carry out a number of complex operations in order to do this. Is there a straightforward, user-friendly way to log ETW events to a file? Also, is it possible for someone to consume ETW events on Windows Vista/7 if they are not running as administrator?

• RPG Game loop and class structure (cocos2D for iPhone)

  - by mac_55

  I'm looking to make an RPG with Cocos2D on the iPhone. I've done a fair bit of research, and I really like the model Cocos2D uses for scenes. I can instantiate a scene, set up my characters etc. and it all works really nicely... what I have problems with is structuring a game loop and separating the code from the scenes. For example, where do I put my code that will maintain the state of the game across multiple scenes? and do I put the code for events that get fired in a scene in that scene's class? or do I have some other class that separates the init code from the logic? Also, I've read a lot of tutorials that mention changing scenes, but I've read none that talk about updating a scene - taking input from the user and updating the display based on that. Does that happen in the scene object, or in a separate display engine type class. Thanks in advance!

• problem with jsf / icefaces depended form fields and validation

  - by hubertg

  Hi, I have a form with 3 fields (simplyfied example). The first one is a checkbox. <ice:selectBooleanCheckBox value=#{backingBean.bean.visible} ID=checkbox1 partialSubmit=true> The second one is a <ice:inputText ID=text1> The third one is also a <ice:inputText ID=text2> text1 should only be visible when checkbox1 is checked. text2 is a required field. So my first approach with just using #{backingBean.bean.visible} failed because text2 has is required and a validation message appeared (after the checkbox was clicked) when the text2 field is empty. Because of ths valdation error the form was never completely submitted such that the visible property is set (update model phase was never reached). So my question: how can I make sure text1 is only visible when checkbox1 is clicked? Thanks.

• Symfony dynamic subdomains

  - by Jamie

  Hi all, I'm trying to match subdomains to a customer id in symfony. i.e. i have customer1.example.com and customer2.example.com Domains are stored in a table. When a user goes to customer1.example.com, I would like to get the subdomain, look up the domain name in the database, once matched, it will then deploy the app config for that customer and then store the customer_Id in a global attribute so i know exactly which customer I'm dealing with througout the whole application. The virtual host will have the relevant wildcard servername. Have you managed to achieve this, and if so, how? If not, any ideas would be a great help! I'm thinking about using a filter to do it. :-)

• MVC Ajax.ActionLink doesn't find POST method

If I remove the POST restriction from the UpdateComments method in the controller, it works fine. What am I missing?

• Webmail client that can open multiple email addresses at once like a desktop client

  - by Trent

  I've got 5 email domains with multiple email addresses on each domain. Traditional webmail clients only seem to allow you to browse a single account at a time (ie, you log into that account). With over 20 email addresses I need to monitor, this is obviously a major time sink. Is there a (preferably OSS, unix-based) webmail client that simulates a desktop email client, ie I log in once and can access all the email addresses from a central control panel? I've considered using a ticket system but that is overkill and not really used to my needs.

• ajax call through cas

  - by manu1001

  I need to write a google gadget that reads feeds from google groups. Trouble is I'm making an ajax call to retrieve the feeds and our google apps domain is protected by CAS (central authentication service). So, I'm getting a 400 bad request on making the call. I suspect that the browser is not sending the cookie when making ajax call. How do I ensure that the cookie is also sent with the ajax call? OR if that's not supposed to be the problem, what do i need to do?

• ItemsControl.ItemsSource MVVM perormance

  - by bitbonk

  I have an (non-virtualized) ItemsControl that binds its ItemsSource to a ObeservableCollection of ViewModel instances. Now once the large amount Model instances is loaded all the ViewModel complemnents needs to be added to that ObservableCollection. How can I add a large amount of ViewModels without making the UI Thread hang? I suppose the UI Thread hangs because each time a new item is added the ItemsControl needs to update itself and does layout etc. over and over again. Should I suspend the binding add all items and then resume? If so, how? Should I override the ObservableCollection to implement an AddRange so only 1 CollectionChanged Event is fired for adding multiple items? Or alternatively just replace the whole collection? Or is it better to add each items separately and call Dispatcher.Invoke for each item separately? So I would unblock frequently. How do you handle large dynamic lists that can not be virtualized?

• Translate query to NHibernate

  - by Rob Walker

  I am trying to learn NHibernate, and am having difficulty translating a SQL query into one using the criteria API. The data model has tables: Part (Id, Name, ...), Order (Id, PartId, Qty), Shipment (Id, PartId, Qty) For all the parts I want to find the total quantity ordered and the total quantity shipped. In SQL I have: select shipment.part_id, sum(shipment.quantity), sum(order.quantity) from shipment cross join order on order.part_id = shipment.part_id group by shipment.part_id Alternatively: select id, (select sum(quantity) from shipment where part_id = part.id), (select sum(quantity) from order where part_id = part.id) from part But the latter query takes over twice as long to execute. Any suggestions on how to create these queries in (fluent) NHibernate? I have all the tables mapped and loading/saving/etc the entities works fine.

• Graphing perpendicular offsets in a least squares regression plot in R

• Getting ActiveRecord (Rails) to_xml to use xsi:nil and xsi:type instead of nil and type

  - by nbeyer

  The default behavior of XML serialization (to_xml) for ActiveRecord objects will emit 'type' and 'nil' attributes that are similar to XML Schema Instance attributes, but aren't set in a XML Namespace. For example, a model might produce an output like this: <user> <username nil="true" /> <first-name type="string">Name</first-name> </user> Is there anyway to get to_xml to utilize the XML Schema Instance namespace and prefix the attributes and the values? Using the above example, I'd like to produce the following: <user xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:xs="http://www.w3.org/1999/XMLSchema"> <username xsi:nil="true" /> <first-name xsi:type="xs:string">Name</first-name> </user>
