wcf - Server Architecture of Real-Time Updates App -

-

I am creating a stock ticker which requires continuous real time updates Network speakers with WCF 4.5 Javascript on the client, which introduced support for WebSockets.

Users' feeds vary widely; for example, many users adhere to popular large caps like FB, GOOG and MSFT, but each user follows several other "niche" shares which are for them Can be unique.

We all know that some options are refreshing the browser in real-time.

  1. Polling Professionals: Easy implementation Cons: Primitive, primitive, do not scale the waste bandwidth and chakras.

  2. Long time voting professionals: skilled, scalable. Cons: Old?

  3. WebSocket Professionals Efficient, scalable Opposition: Nobody can think that they support them as the most modern browsers.

    Can anyone choose anything more than 3?

    3. With, how is the track of open connection of the server kept? For example, if we design such that we maintain a pool of FB "followers" (i.e., customer connections interested in change in value of FB), then we know that when the price changes, So how is this pool maintained? From a service that keeps running in memory? In addition, if an FB follower closes his or her browser, does the service need to capture this event and update FB's follower pool? This is where I get fuzzy quickly.

    Check out this post about the hard sides of long posting:

    < P> How is the track of open connection of the server kept?

    Perhaps there is a way to connect and disconnect in WCF websacettes, if not, should definitely keep an eye on other frameworks I took a look at WCF websites some time ago, and Nothing looks like what I would like to use, by putting aside one, you will need Windows 8 or Windows 2012 to use it.

    You should like websites just and closing points, you should develop your stock ticker software with an event-driven architecture approach, and then provide an end point to receive / obtain the event, Which will be a totally different part of the app. I advise you for event management.

    When you have this clear, you can determine how the user will engage with your service and interact with it. In the architecture operated by web events, websites make great sense because it has full duplex, constant connection and widely supported web standards.

    To provide web cachet to .NET, WCF is not the only option, and it may not be best to add a websocket endpoint to your architecture, I recommend you use the webcott There is a very small component to provide the capability (Disclaimer: I have developed it), or if you want a more complex solution that does many things. See this example made with XSocket.NET:

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
