• F#: Advantages of converting top-level functions to member methods?

  - by J Cooper

  Earlier I requested some feedback on my first F# project. Before closing the question because the scope was too large, someone was kind enough to look it over and leave some feedback. One of the things they mentioned was pointing out that I had a number of regular functions that could be converted to be methods on my datatypes. Dutifully I went through changing things like let getDecisions hand = let (/=/) card1 card2 = matchValue card1 = matchValue card2 let canSplit() = let isPair() = match hand.Cards with | card1 :: card2 :: [] when card1 /=/ card2 -> true | _ -> false not (hasState Splitting hand) && isPair() let decisions = [Hit; Stand] let split = if canSplit() then [Split] else [] let doubleDown = if hasState Initial hand then [DoubleDown] else [] decisions @ split @ doubleDown to this: type Hand // ...stuff... member hand.GetDecisions = let (/=/) (c1 : Card) (c2 : Card) = c1.MatchValue = c2.MatchValue let canSplit() = let isPair() = match hand.Cards with | card1 :: card2 :: [] when card1 /=/ card2 -> true | _ -> false not (hand.HasState Splitting) && isPair() let decisions = [Hit; Stand] let split = if canSplit() then [Split] else [] let doubleDown = if hand.HasState Initial then [DoubleDown] else [] decisions @ split @ doubleDown Now, I don't doubt I'm an idiot, but other than (I'm guessing) making C# interop easier, what did that gain me? Specifically, I found a couple *dis*advantages, not counting the extra work of conversion (which I won't count, since I could have done it this way in the first place, I suppose, although that would have made using F# Interactive more of a pain). For one thing, I'm now no longer able to work with function "pipelining" easily. I had to go and change some |> chained |> calls to (some |> chained).Calls etc. Also, it seemed to make my type system dumber--whereas with my original version, my program needed no type annotations, after converting largely to member methods, I got a bunch of errors about lookups being indeterminate at that point, and I had to go and add type annotations (an example of this is in the (/=/) above). I hope I haven't come off too dubious, as I appreciate the advice I received, and writing idiomatic code is important to me. I'm just curious why the idiom is the way it is :) Thanks!

• Facebook Graph API and ActionScript

  - by dani

  I'm setting out to develop a number of Facebook applications/games, which make use of some Facebook user information and stores game info in a database backend etc, in ActionScript 3.0. How can one leverage the new Graph API Should I use JavaScript or PHP as a "middle layer" or should I go with the ActionScript Client Library? Are there other libraries (Facebook / database / multiplayer related.) that could simplify the development of these Facebook games?

• (RAD Studio) Virtual TreeView: how to initialize all nodes at once?

  - by Andrew

  Hi, I just discovered this component and started working with it. I understand that the whole concept of it is to initialize nodes on the go as they are needed but I need all of them to initialize instantly. What is the smart way to do it? The only thing I came up with is to use GetLast() after adding nodes. I believe, there is a better way, or not?

• XAML ToolTip + IsHitTestVisible="False"

  - by Sean

  We need to have mouse clicks and drags "ignored" by our View1 but the ToolTip must still function in that view. The reason is View1 is above View2 in Z-Order, so View1 can tint View2 a red color and show a warning via ToolTip; however the ToolTip accompanying View1 will not work if IsHitTestVisible="False". Anyone know a work around so the ToolTip will display on mouse move/over and the rest of mouse events are ignored by View1 and go to View2? Thanks, Sean

• Best tool for DOM manipulation ?

  - by Olivier Lalonde

  I'm working on a web scraper which will aggregate data from various websites. I've started using PHP's built in DOM functions but after running into a couple of issues (especially regarding malformed markup and character encoding), I've chosen to ditch PHP. I was thinking of server side Javascript but am open to other suggestions. If I go with Javascript, which interpreter should I use?

• When should the BDD test scenarios be written?

  - by Si Keep

  I am looking into BDD testing within a scrum scenario and realise that the BDD scenarios are more akin to specifications than tests. Therefore should they be written before the developers go into pre-planning so that all of the functionality has been identified which would allow better estimating, prioritisation etc in that meeting?

• Client-side policy error using JacORB (Java/CORBA) with SSL

  - by jason

  I'm trying to add SSL to an existing CORBA app, and I keep getting this error: org.omg.CORBA.NO_PERMISSION: Client-side policy requires SSL/TLS, but server doesn't support it vmcid: 0x0 minor code: 0 completed: No at org.jacorb.orb.iiop.ClientIIOPConnection.checkSSL(ClientIIOPConnection.java:535) at org.jacorb.orb.iiop.ClientIIOPConnection.connect(ClientIIOPConnection.java:144) at org.jacorb.orb.giop.GIOPConnection.sendMessage(GIOPConnection.java:835) at org.jacorb.orb.giop.GIOPConnection.sendRequest(GIOPConnection.java:805) at org.jacorb.orb.giop.ClientConnection.sendRequest(ClientConnection.java:302) at org.jacorb.orb.giop.ClientConnection.sendRequest(ClientConnection.java:282) at org.jacorb.orb.Delegate.invoke_internal(Delegate.java:919) at org.jacorb.orb.Delegate.invoke(Delegate.java:868) at org.jacorb.orb.Delegate.is_a(Delegate.java:1268) at org.omg.CORBA.portable.ObjectImpl._is_a(ObjectImpl.java:112) at databridge.autogen.ILoginManagerHelper.narrow(ILoginManagerHelper.java:57) at databridge.test.Client.main(Client.java:59) I have generated keystores for both client and server and exchanged the keys between the two. Using this setup, I can get the demo application that came in the JacORB download to run successfully. The only difference I can tell is that my test is using the Tie method to get the POA. There are some policies that go into that, but I can't find any information on what policies need to go in there to enable SSL, if any. I'm not even sure that's the problem as the JacORB demo doesn't set any policies on the server or poa. When I run the -Djavax.net.debug=ssl, I can see the keystores load up the trusted certs on both the client and the server. I'm just not sure what policies are being referred to here, but it's odd that the demo works and the test doesn't using the exact same keystores and properties. I've emailed the mailing list, but I'm not holding out much hope as that doesn't seem to be very active. Any help would be greatly appreciated. Below are my properties files.

• Unity framework - creating & disposing Entity Framework datacontexts at the appropriate time

  - by TobyEvans

  Hi there, With some kindly help from StackOverflow, I've got Unity Framework to create my chained dependencies, including an Entity Framework datacontext object: using (IUnityContainer container = new UnityContainer()) { container.RegisterType<IMeterView, Meter>(); container.RegisterType<IUnitOfWork, CommunergySQLiteEntities>(new ContainerControlledLifetimeManager()); container.RegisterType<IRepositoryFactory, SQLiteRepositoryFactory>(); container.RegisterType<IRepositoryFactory, WCFRepositoryFactory>("Uploader"); container.Configure<InjectedMembers>() .ConfigureInjectionFor<CommunergySQLiteEntities>( new InjectionConstructor(connectionString)); MeterPresenter meterPresenter = container.Resolve<MeterPresenter>(); this works really well in creating my Presenter object and displaying the related view, I'm really pleased. However, the problem I'm running into now is over the timing of the creation and disposal of the Entity Framework object (and I suspect this will go for any IDisposable object). Using Unity like this, the SQL EF object "CommunergySQLiteEntities" is created straight away, as I've added it to the constructor of the MeterPresenter public MeterPresenter(IMeterView view, IUnitOfWork unitOfWork, IRepositoryFactory cacheRepository) { this.mView = view; this.unitOfWork = unitOfWork; this.cacheRepository = cacheRepository; this.Initialize(); } I felt a bit uneasy about this at the time, as I don't want to be holding open a database connection, but I couldn't see any other way using the Unity dependency injection. Sure enough, when I actually try to use the datacontext, I get this error: ((System.Data.Objects.ObjectContext)(unitOfWork)).Connection '((System.Data.Objects.ObjectContext)(unitOfWork)).Connection' threw an exception of type 'System.ObjectDisposedException' System.Data.Common.DbConnection {System.ObjectDisposedException} My understanding of the principle of IoC is that you set up all your dependencies at the top, resolve your object and away you go. However, in this case, some of the child objects, eg the datacontext, don't need to be initialised at the time the parent Presenter object is created (as you would by passing them in the constructor), but the Presenter does need to know about what type to use for IUnitOfWork when it wants to talk to the database. Ideally, I want something like this inside my resolved Presenter: using(IUnitOfWork unitOfWork = new NewInstanceInjectedUnitOfWorkType()) { //do unitOfWork stuff } so the Presenter knows what IUnitOfWork implementation to use to create and dispose of straight away, preferably from the original RegisterType call. Do I have to put another Unity container inside my Presenter, at the risk of creating a new dependency? This is probably really obvious to a IoC guru, but I'd really appreciate a pointer in the right direction thanks Toby

• How do I create midi data to trigger an Ultrabeat pattern in Logic?

  - by user289581

  I've made some Ultrabeat patterns but I can't figure out how to trigger them. I make the pattern on C-1, then I go back to the arrange window and hit record and then hit C1 on my keyboard, and it doesn't play the pattern, it just plays a single note. I have Pattern Mode enabled on Ultrabeat and I'm using a one-shot trigger but I can't seem to trigger my pattern to play at all. What am I doing wrong?
