• How many per-core licenses do I need?

  - by GavinPayneUK

    With SQL Server 2012, your licensing requirements can chose to use or be required to use a per-core model depending on the edition you’re deploying. This is a change to previous editions which used a per-CPU socket model that made counting how many per-CPU licences you needed easier – cores and HyperThreading didn’t influence the CPU socket count.  Any complications which people did have typically came from running SQL Server in a virtualised environment, was a vCPU a socket or did licensing...(read more)

• Should I use JavaFx properties?

  - by Mike G

  I'm usually very careful to keep my Model, View, and Controller code separate. The thing is JavaFx properties are so convenient to bind them all together. The issue is that it makes my entire code design dependent on JavaFx, which I feel I should not being doing. I should be able to change the view without changing too much of the model and controller. So should I ignore the convenience of JavaFx properties, or should I embrace them and the fact that it reduces my codes flexibility.

• Addressing threats introduced by the BYOD trend

  - by kyap

  With the growth of the mobile technology segment, enterprises are facing a new type of threats introduced by the BYOD (Bring Your Own Device) trend, where employees use their own devices (laptops, tablets or smartphones) not necessarily secured to access corporate network and information.In the past - actually even right now, enterprises used to provide laptops to their employees for their daily work, with specific operating systems including anti-virus and desktop management tools, in order to make sure that the pools of laptop allocated are spyware or trojan-horse free to access the internal network and sensitive information. But the BYOD reality is breaking this paradigm and open new security breaches for enterprises as most of the username/password based systems, especially the internal web applications, can be accessed by less or none protected device.To address this reality we can adopt 3 approaches:1. Coué's approach: Close your eyes and assume that your employees are mature enough to know what he/she should or should not do.2. Consensus approach: Provide a list of restricted and 'certified' devices to the internal network. 3. Military approach: Access internal systems with certified laptop ONLYIf you choose option 1: Thanks for visiting my blog and I hope you find the others entries more useful :)If you choose option 2: The proliferation of new hardware and software updates every quarter makes this approach very costly and difficult to maintain.If you choose option 3: You need to find a way to allow the access into your sensitive application from the corporate authorized machines only, managed by the IT administrators... but how? The challenge with option 3 is to find out how end-users can restrict access to certain sensitive applications only from authorized machines, or from another angle end-users can not access the sensitive applications if they are not using the authorized machine... So what if we find a way to store the applications credential secretly from the end-users, and then automatically submit them when the end-users access the application? With this model, end-users do not know the username/password to access the applications so even if the end-users use their own devices they will not able to login. Also, there's no need to reconfigure existing applications to adapt to the new authenticate scheme given that we are still leverage the same username/password authenticate model at the application level. To adopt this model, you can leverage Oracle Enterprise Single Sign On. In short, Oracle ESSO is a desktop based solution, capable to store credentials of Web and Native based applications. At the application startup and if it is configured as an esso-enabled application - check out my previous post on how to make Skype essso-enabled, Oracle ESSO takes over automatically the sign-in sequence with the store credential on behalf of the end-users. Combined with Oracle ESSO Provisioning Gateway, the credentials can be 'pushed' in advance from an actual provisioning server, like Oracle Identity Manager or Tivoli Identity Manager, so the end-users can login into sensitive application without even knowing the actual username and password, so they can not login with other machines rather than those secured by Oracle ESSO.Below is a graphical illustration of this approach:With this model, not only you can protect the access to sensitive applications only from authorized machine, you can also implement much stronger Password Policies in terms of Password Complexity as well as Password Reset Frequency but end-users will not need to remember the passwords anymore.If you are interested, do not hesitate to check out the Oracle Enterprise Single Sign-on products from OTN !

• Should I use AND or should I use OR

  - by BDotA

  An order can be in the "status" of Completed, Corrected or some other stratus. I saw some code that is checking it like this, the purpose is to disable some stuff when the status is in Completed or Corrected status. if (model.CurrentStatus != DSRHelper.OrderStatusEnum.Complete && model.CurrentStatus != DSRHelper.OrderStatusEnum.Corrected) I can't get it why the engineer has used "AND" for this, shouldn't it be an "OR"?

• Need to make animation whereby the character shatters into a bunch of pieces

  - by theprojectabot

  I would like to take a 3d character model, cut out a bunch of shapes (or a bunch of triangles in the shape of the pieces I want) and then have the pieces separate from each other at the beginning of the animation and fall apart with gravity so it looks like the model is falling apart in shattered pieces. Is there a way to run a script on a mesh, cut out these pieces, instantiate all of them as separate models and then run gravity on them during the simulation?

• Welcome to ubiquitous file sharing (December 08, 2009)

  - by user12612012

  The core of any file server is its file system and ZFS provides the foundation on which we have built our ubiquitous file sharing and single access control model.  ZFS has a rich, Windows and NFSv4 compatible, ACL implementation (ZFS only uses ACLs), it understands both UNIX IDs and Windows SIDs and it is integrated with the identity mapping service; it knows when a UNIX/NIS user and a Windows user are equivalent, and similarly for groups.  We have a single access control architecture, regardless of whether you are accessing the system via NFS or SMB/CIFS.The NFS and SMB protocol services are also integrated with the identity mapping service and shares are not restricted to UNIX permissions or Windows permissions.  All access control is performed by ZFS, the system can always share file systems simultaneously over both protocols and our model is native access to any share from either protocol.Modal architectures have unnecessary restrictions, confusing rules, administrative overhead and weird deployments to try to make them work; they exist as a compromise not because they offer a benefit.  Having some shares that only support UNIX permissions, others that only support ACLs and some that support both in a quirky way really doesn't seem like the sort of thing you'd want in a multi-protocol file server.  Perhaps because the server has been built on a file system that was designed for UNIX permissions, possibly with ACL support bolted on as an add-on afterthought, or because the protocol services are not truly integrated with the operating system, it may not be capable of supporting a single integrated model.With a single, integrated sharing and access control model: If you connect from Windows or another SMB/CIFS client: The system creates a credential containing both your Windows identity and your UNIX/NIS identity.  The credential includes UNIX/NIS IDs and SIDs, and UNIX/NIS groups and Windows groups. If your Windows identity is mapped to an ephemeral ID, files created by you will be owned by your Windows identity (ZFS understands both UNIX IDs and Windows SIDs). If your Windows identity is mapped to a real UNIX/NIS UID, files created by you will be owned by your UNIX/NIS identity. If you access a file that you previously created from UNIX, the system will map your UNIX identity to your Windows identity and recognize that you are the owner.  Identity mapping also supports access checking if you are being assessed for access via the ACL. If you connect via NFS (typically from a UNIX client): The system creates a credential containing your UNIX/NIS identity (including groups). Files you create will be owned by your UNIX/NIS identity. If you access a file that you previously created from Windows and the file is owned by your UID, no mapping is required. Otherwise the system will map your Windows identity to your UNIX/NIS identity and recognize that you are the owner.  Again, mapping is fully supported during ACL processing. The NFS, SMB/CIFS and ZFS services all work cooperatively to ensure that your UNIX identity and your Windows identity are equivalent when you access the system.  This, along with the single ACL-based access control implementation, results in a system that provides that elusive ubiquitous file sharing experience.

• Rendering My Fault Message

  - by onefloridacoder

  My coworkers setup  a nice way to get the fault messages from our service layer all the way back to the client’s service proxy layer.  This is what I needed to work on this afternoon.  Through a series of trials and errors I finally figured this out. The confusion was how I was looking at the exception in the quick watch viewer.  It appeared as though the EventArgs from the service call had somehow magically been cast back to FaultException(), not FaultException<T>.  I drilled into the EventArgs object with the quick watch and I copied this code to figure out where the Fault message was hiding.  Further, when I copied this quick watch code into the IDE I got squigglies.  Poop. 1: ((System 2: .ServiceModel 3: .FaultException<UnhandledExceptionFault>)(((System.Exception)(e.Result)).InnerException)).Detail.FaultMessage I wont bore you with the details but here’s how it turned out.   EventArgs which I’m calling “e” is not the result such as some collection of items you’re expecting.  It’s actually a FaultException, or in my case FaultException<T>.  Below is the calling code and the callback to handle the expected response or the fault from the completed event. 1: public void BeginRetrieveItems(Action<ObservableCollection<Model.Widget>> FindItemsCompleteCallback, Model.WidgetLocation location) 2: { 3: var proxy = new MyServiceContractClient(); 4:  5: proxy.RetrieveWidgetsCompleted += (s, e) => FindWidgetsCompleteCallback(FindWidgetsCompleted(e)); 6:  7: RetrieveWidgetsRequest request = new RetrieveWidgetsRequest { location.Id }; 8:  9: proxy.RetrieveWidgetsAsync(request); 10: } 11:  12: private ObservableCollection<Model.Widget> FindItemsCompleted(RetrieveWidgetsCompletedEventArgs e) 13: { 14: if (e.Error is FaultException<UnhandledExceptionFault>) 15: { 16: var fault = (FaultException<UnhandledExceptionFault>)e.Error; 17: var faultDetailMessage = fault.Detail.FaultMessage; 18:  19: UIMessageControlDuJour.Show(faultDetailMessage); 20: return new ObservableCollection<BinInventoryItemCountInfo>(); 21: } 22:  23: var widgets = new ObservableCollection<Model.Widget>(); 24:  25: if (e.Result.Widgets != null) 26: { 27: e.Result.Widgets.ToList().ForEach(w => widgets.Add(this.WidgetMapper.Map(w))); 28: } 29:  30: return widgets; 31: }

• What is the architectural name for the set of data that enables UI choices?

  - by Richard Collette

  I have separate service methods that fetch business object data and the data for UI selection input such as radio buttons, check-boxes, combo-boxes, etc. I want to name my service methods that fetch the selection data appropriately. I am assuming that Model and ViewModel would not be part of the name because the selection data is but a portion of the Model or ViewModel. What might this set of data be named such that I can name my service method?

• Help with calculation to steer ship in 3d space

  - by Aaron Anodide

  I'm a beginner using XNA to try and make a 3D Asteroids game. I'm really close to having my space ship drive around as if it had thrusters for pitch and yaw. The problem is I can't quite figure out how to translate the rotations, for instance, when I pitch forward 45 degrees and then start to turn - in this case there should be rotation being applied to all three directions to get the "diagonal yaw" - right? I thought I had it right with the calculations below, but they cause a partly pitched forward ship to wobble instead of turn.... :( Here's current (almost working) calculations for the Rotation acceleration: float accel = .75f; // Thrust +Y / Forward if (currentKeyboardState.IsKeyDown(Keys.I)) { this.ship.AccelerationY += (float)Math.Cos(this.ship.RotationZ) * accel; this.ship.AccelerationX += (float)Math.Sin(this.ship.RotationZ) * -accel; this.ship.AccelerationZ += (float)Math.Sin(this.ship.RotationX) * accel; } // Rotation +Z / Yaw if (currentKeyboardState.IsKeyDown(Keys.J)) { this.ship.RotationAccelerationZ += (float)Math.Cos(this.ship.RotationX) * accel; this.ship.RotationAccelerationY += (float)Math.Sin(this.ship.RotationX) * accel; this.ship.RotationAccelerationX += (float)Math.Sin(this.ship.RotationY) * accel; } // Rotation -Z / Yaw if (currentKeyboardState.IsKeyDown(Keys.K)) { this.ship.RotationAccelerationZ += (float)Math.Cos(this.ship.RotationX) * -accel; this.ship.RotationAccelerationY += (float)Math.Sin(this.ship.RotationX) * -accel; this.ship.RotationAccelerationX += (float)Math.Sin(this.ship.RotationY) * -accel; } // Rotation +X / Pitch if (currentKeyboardState.IsKeyDown(Keys.F)) { this.ship.RotationAccelerationX += accel; } // Rotation -X / Pitch if (currentKeyboardState.IsKeyDown(Keys.D)) { this.ship.RotationAccelerationX -= accel; } I'm combining that with drawing code that does a rotation to the model: public void Draw(Matrix world, Matrix view, Matrix projection, TimeSpan elsapsedTime) { float seconds = (float)elsapsedTime.TotalSeconds; // update velocity based on acceleration this.VelocityX += this.AccelerationX * seconds; this.VelocityY += this.AccelerationY * seconds; this.VelocityZ += this.AccelerationZ * seconds; // update position based on velocity this.PositionX += this.VelocityX * seconds; this.PositionY += this.VelocityY * seconds; this.PositionZ += this.VelocityZ * seconds; // update rotational velocity based on rotational acceleration this.RotationVelocityX += this.RotationAccelerationX * seconds; this.RotationVelocityY += this.RotationAccelerationY * seconds; this.RotationVelocityZ += this.RotationAccelerationZ * seconds; // update rotation based on rotational velocity this.RotationX += this.RotationVelocityX * seconds; this.RotationY += this.RotationVelocityY * seconds; this.RotationZ += this.RotationVelocityZ * seconds; Matrix translation = Matrix.CreateTranslation(PositionX, PositionY, PositionZ); Matrix rotation = Matrix.CreateRotationX(RotationX) * Matrix.CreateRotationY(RotationY) * Matrix.CreateRotationZ(RotationZ); model.Root.Transform = rotation * translation * world; model.CopyAbsoluteBoneTransformsTo(boneTransforms); foreach (ModelMesh mesh in model.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.World = boneTransforms[mesh.ParentBone.Index]; effect.View = view; effect.Projection = projection; effect.EnableDefaultLighting(); } mesh.Draw(); } }

• Is there a factory pattern to prevent multiple instances for same object (instance that is Equal) good design?

  - by dsollen

  I have a number of objects storing state. There are essentially two types of fields. The ones that uniquely define what the object is (what node, what edge etc), and the others that store state describing how these things are connected (this node is connected to these edges, this edge is part of these paths) etc. My model is updating the state variables using package methods, so all these objects act as immutable to anyone not in Model scope. All Objects extend one base type. I've toyed with the idea of a Factory approach which accepts a Builder object and constructs the applicable object. However, if an instance of the object already exists (ie would return true if I created the object defined by the builder and passed it to the equal method for the existing instance) the factory returns the current object instead of creating a new instance. Because the Equal method would only compare what uniquely defines the type of object (this is node A to node B) but won't check the dynamic state stuff (node A is currently connected to nodes C and E) this would be a way of ensuring anyone that wants my Node A automatically knows its state connections. More importantly it would prevent aliasing nightmares of someone trying to pass an instance of node A with different state then the node A in my model has. I've never heard of this pattern before, and it's a bit odd. I would have to do some overriding of serialization methods to make it work (ensure that when I read in a serilized object I add it to my facotry list of known instances, and/or return an existing factory in its place), as well as using a weakHashMap as if it was a weakHashSet to know whether an instance exists without worrying about a quasi-memory leak occuring. I don't know if this is too confusing or prone to its own obscure bugs. One thing I know is that plugins interface with lowest level hardware. The plugins have to be able to return state that is different than my memory; to tell my memory when its own state is inconsistent. I believe this is possible despite their fetching objects that exist in my memory; we allow building of objects without checking their consistency with the model until the addToModel is called anyways; and the existing plugins design was written before all this extra state existed and worked fine without ever being aware of it. Should I just be using some other design to avoid this crazyness? (I have another question to that affect that I'm posting).

• Entity and pattern validation vs DB constraint

  - by Joerg

  When it comes to performance: What is the better way to validate the user input? If you think about a phone number and you only want numbers in the database, but it could begin with a 0, so you will use varchar: Is it better to check it via the entity model like this: @Size(min = 10, max = 12) @Digits(fraction = 0, integer = 12) @Column(name = "phone_number") private String phoneNumber; Or is it better to use on the database side a CHECK (and no checking in the entity model) for the same feature?

• Get selected object from TreeView

  I've been working on a minor (first time) app with quickly and hit a hurdle - how do I get the selected row (the data) from a TreeView? The data to the TreeView is passed from a list of files in a directory, and I need to know which rows were selected (and thus which files were). What is the best way to do that? Here's the current code: self.treeview = self.builder.get_object("treeview") select = self.treeview.get_selection() select.connect("changed", self.on_tree_selection_changed) def on_tree_selection_changed(selection): model, treeiter = self.treeview.selection-get() if treeiter != None: print "You selected", model[treeiter][0]

• Cloud Fact for Business Managers #3: Where You Data Is, and Who Has Access to It Might Surprise You

  - by yaldahhakim

  Written by: David Krauss While data security and operational risk conversations usually happen around the desk of a CCO/CSO (chief compliance and/or security officer), or perhaps the CFO, since business managers are now selecting cloud providers, they need to be able to at least ask some high-level questions on the topic of risk and compliance.  While the report found that 76% of adopters were motivated to adopt cloud apps because of quick access to software, most of these managers found that after they made a purchase decision their access to exciting new capabilities in the cloud could be hindered due to performance and scalability constraints put forth  by their cloud provider.  If you are going to let your business consume their mission critical business applications as a service, then it’s important to understand who is providing those cloud services and what kind of performance you are going to get.  Different types of departments, companies and industries will all have unique requirements so it’s key to take this also into consideration.   Nothing puts a CEO in a bad mood like a public data breach or finding out the company lost money when customers couldn’t buy a product or service because your cloud service provider had a problem.  With 42% of business managers having seen a data security breach in their department associated directly with the use of cloud applications, this is happening more than you think.   We’ve talked about the importance of being able to avoid information silos through a unified cloud approach and platform.  This is also important when keeping your data safe and secure, and a key conversation to have with your cloud provider.  Your customers want to know that their information is protected when they do business with you, just like you want your own company information protected.   This is really hard to do when each line of business is running different cloud application services managed by different cloud providers, all with different processes and controls.   It only adds to the complexity, and the more complex, the more risky and the chance that something will go wrong. What about compliance? Depending on the cloud provider, it can be difficult at best to understand who has access to your data, and were your data is actually stored.  Add to this multiple cloud providers spanning multiple departments and it becomes very problematic when trying to comply with certain industry and country data security regulations.  With 73% of business managers complaining that having cloud data handled externally by one or more cloud vendors makes it hard for their department to be compliant, this is a big time suck for executives and it puts the organization at risk. Is There A Complete, Integrated, Modern Cloud Out there for Business Executives?If you are a business manager looking to drive faster innovation for your business and want a cloud application that your CIO would approve of, I would encourage you take a look at Oracle Cloud.  It’s everything you want from a SaaS based application, but without compromising on functionality and other modern capabilities like embedded business intelligence, social relationship management (for your entire business), and advanced mobile.  And because Oracle Cloud is built and managed by Oracle, you can be confident that your cloud application services are enterprise-grade.  Over 25 Million users and 10 thousands companies around the globe rely on Oracle Cloud application services everyday – maybe your business should too.  For more information, visit cloud.oracle.com.

  I'm developing a C# game engine and have hit a snag trying to add physics. I'm using XNA for graphics and Jitter for physics. I am trying to split the XNA model into it's meshes, then create a ConvexHull for each mesh. I then attempt to combine those into a CompoundObject, this however isn't working and depending upon the model the meshes are offset by different amounts.

• Hoster not fulfilling contract: how to get money back?

  - by plua

  For several years, we have as a small webdesign company rented a dedicated server at a large hosting provider. They had several support levels. When we signed up for this, we had very limited in-house knowledge about server maintenance, and were very worried about the security of our server. We therefore took one of the more expensive support packages. An important aspect in this were these claims: [PROVIDER] verifies the availability of the latest security updates and sends you a notification to see if you are interested to have them installed [PROVIDER] verifies the availability of the latest supported software updates and sends you a notification to see if you are interested to have them installed These items were clearly stated on their website as being part of the advantage of this package.; With not enough knowledge about installing and updating such software on a Linux server, we decided to go for this package. We paid a premium of $50 per month over the maintenance package that is next in line ($100 vs $50). Over the years, we have paid several thousand dollars for this service. Then came the moment that I learned more and more about server management. And I found out step by step that our server was horrendously outdated! We had an OS that was hardly updated, our anti-virus was not working because it needed certain more recent packages on the OS, and in general there were a whole bunch of security vulnerabilities and fixes that were lacking. Shocked, I wrote the provider. Turns out, they decided unilaterally that they would not send out any notifications to clients because clients would get too many e-mails. This is a quote from their explanation: [...] We have decided not to spam its clients with OS and security updates and only install them whenever asked by the client I was shocked! They had never mentioned that they would drop this service, and in fact the claims about updating their clients through e-mail was still on their website, after they apparently stopped doing this years ago! Upon finding this out, I requested they refund all that we have paid as a premium over the other package, and make it available as future credit with their own company. I thought this was a very reasonable request. However, they said they would only go back one year and provide credit for this one year. Mails went back and forth, but they were not willing to give credit for the whole period, which I felt I was entitled to. So ultimately I left the hosting company, and filed a complaint with the BBB a while ago. Now, I am not the kind of person who runs to a lawyer for any minor thing, but in this case I am really considering taking action. I have been paying for years for a service I did not receive (the premium package had a few other pluses, but we took it primarily for these two points, and I can prove that we did not use the other benefits). For our small company the hosting costs were a very large part of our budget, and I feel it is very unfair how this large provider just does not care about not fulfilling its obligations. So my question is: what action should I take? Is a lawyer the only next step, or are there other suggestions? And am I right here to claim this money, or are they right that there is some sort of statue of limitations on such claims? Any feedback is appreciated.

• The need to reduce mesh count

  - by OJW

  In Panda3d, I load a model and place 10000 references to it in the scene-graph. It runs at (say) 2Hz. I load a 3d model containing 10000 copies of that exact same object, and it runs at (say) 60Hz. As does using the flattenStrong() command which is effectively the same thing but at runtime. So the question is: is this behaviour a peculiarity of Panda3d, or is it a fundamental law which applies to all games engines?

• Interoperability between Weblogic 10.3.1 and Oracle BPM 10.3.1

  - by alfredozn

  Hi, Im migrating an ALBPM 6.5 running on a WLS 10.0 to an Oracle BPM 10.3.1 running on WLS 10.3.1 I got some problems with the Oracle driver because the old driver (weblogic.jdbcx.oracle.OracleDataSource) was definitely removed from the server and is not longer supported. Instead I used the thin driver (oracle.jdbc.xa.OracleXADataSource), the database migration was executed succesfully but after that, when I try to deploy the engine ear in WebLogic I got exceptions asociated to the driver: [ (cont) ] Main: Caused by: weblogic.application.ModuleException: [HTTP:101216]Servlet: "engineStartup" failed to preload on startup in Web application: "/albpmServices/albpm_engine". [ (cont) ] Main: fuego.directory.DirectoryRuntimeException: Exception [java.sql.SQLException: Invalid column type]. [ (cont) ] Main: at fuego.directory.DirectoryRuntimeException.wrapException(DirectoryRuntimeException.java:85) [ (cont) ] Main: at fuego.directory.provider.jdbc.oracle.OraclePersistenceManager.mapSQLException(OraclePersistenceManager.java:145) [ (cont) ] Main: at fuego.directory.provider.jdbc.datadirect.oracle.DataDirectOraclePersistenceManager.mapSQLException(DataDirectOraclePersistenceManager.java:51) [ (cont) ] Main: at fuego.directory.provider.jdbc.JDBCServiceAccessor.mapSQLException(JDBCServiceAccessor.java:78) [ (cont) ] Main: at fuego.directory.provider.jdbc.JDBCObjectPropertiesAccessor.fetchAllDirectoryProperties(JDBCObjectPropertiesAccessor.java:442) [ (cont) ] Main: at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) I was looking around for a solution but all is pointing to use the old driver, I think isn't a good practice to force the server to use this driver after Oracle remove it completely. Any suggestions or similar experiences??

• trying to get the most accurate device location from GPS or Network in Android

  - by arc

  I am trying to determine the most accurate location of a device, in the shortest time possible. I am storing the data as a geopoint, and have it displayed on a mapview. The last time I activated the GPS on my device and let it get a location lock, i was approx 80 miles from where I am now. I have a location manager setup and a location listener. If I do this, I get NULL. myLocOverlay = new MyLocationOverlay(this, mapView); GeoPoint test = myLocOverlay.getMyLocation(); but in the next couple of lines; myLocOverlay.enableMyLocation(); mapView.getOverlays().add(myLocOverlay); With this, the overlay on the map shows the current location. It is using the Network provider, but is also attempting to get a GPS fix (it can't as I am indoors and no where near the top floor). If I construct the geopoint like this; if(lm.getLastKnownLocation("gps") != null) { test = new GeoPoint( (int) (lm.getLastKnownLocation("gps").getLatitude() * 1E6), (int) (lm.getLastKnownLocation("gps").getLongitude() * 1E6)); } else { if(lm.getLastKnownLocation("network") != null) { test = new GeoPoint( (int) (lm.getLastKnownLocation("network").getLatitude() * 1E6), (int) (lm.getLastKnownLocation("network").getLongitude() * 1E6)); } //bad things } Then I get confusing results. If I disable the devices GPS provider then the code moves onto the Network Provider and gives me a fairly accurate result. If I enable the GPS provider, then the geopoint comes back as the last place I allowed the device to get a GPS lock. I want to avoid the above results, and so was looking at using; GeoPoint test = myLocOverlay.getMyLocation(); BUT as I said above, I just get NULL from that. Short of getting the geopoints from both GPS and Network and then comparing them, and disregarding the GPS result if it is say 1 mile out of the Network location - i'm a bit stuck. why doesn't getMyLocation() work, shouldnt that return the GeoPoint of what myLocOverlay is showing on the mapview?

• Creating custom IP-STS for sharepoint foundation 2010 without ADFS

  - by user252229

  I plan to create very simple custom IP-STS for SharePoint foundation 2010 without ADFS server so anyone can integrate Windows Live ID to SharePoint foundation 2010 simply without ADFS, I can't use ADFS server because it could not install on Windows Web Server 2008 (Web Edition), also I found many article use LDAP provider but it does not exists in SharePoint Foundation too (it requires Sharepoint Server Edition). After too much searching I just found the following article and find all technique except one problem. 1) Creating Custom Claim Provider: blogs.technet.com/b/speschka/archive/2010/03/13/writing-a-custom-claims-provider-for-sharepoint-2010-part-1.aspx 2) Creating Custom STS Provider: http://blogs.msdn.com/b/chunliu/archive/2010/04/02/how-to-make-use-of-a-custom-ip-sts-with-sharepoint-2010-part-1.aspx Only one step remains: I got following error after enter username in STS site and redirect to localhost/_trust/default.aspx , ( I leave EncryptingCertificateName empty). Operation is not valid due to the current state of the object I expect to get access denied error instead of that error. 1.Is it possible anyway? 2.Can anyone help me where can I find working article to create custom IP-STS without ADFS server Any idea will help me Thanks
