  • Backing up my locally hosted rails apps in preparation for OS upgrade

    - by stephen murdoch
    I have some apps running on Heroku. I will be upgrading my OS in two weeks. The last time I upgraded though (6 months ago) I ran into some problems. Here's what I did: copied all my rails apps onto DVD upgraded OS transferred rails apps from DVD to new OS Then, after setting up new SSH-keys I tried to push to some of my heroku apps and, whilst I can't remember the exact error message off-hand, it more or less amounted to "fatal exception the remote end hung up" So I know that I'm doing something wrong here. First of all, is there any need for me to be putting my heroku hosted rails apps onto DVD? Would I be better just pulling all my apps from their heroku repos once I've done the upgrade? What do others do here? The reason I stuck them on DVD is because I tend to push a specific production branch to Heroku and sometimes omit large development files from it... Secondly, was this problem caused by SSH keys? Should I have backed up the old keys and transferred them from my old OS to my new one too, or is Heroku perfectly happy to let you change OS's like that? My solution in the end was to just create new heroku apps and reassign the custom domain names in heroku add-ons menu... I never actually though of pulling from the heroku repos as I tend to push a specific branch to heroku and that branch doesn't always have all the development files in it... I realise that the error message I mentioned doesn't particularly help anyone but I didn't think to remember it 6 months ago. Any advice would be appreciated PS - when I say upgrade, I mean full install of the new version with full format of the HDD.

  • Flash AS3 load file xml

    - by Elias
    Hello, I'm just trying to load an xml file witch can be anywere in the hdd, this is what I have done to browse it, but later when I'm trying to load the file it would only look in the same path of the swf file here is the code package { import flash.display.Sprite; import flash.events.; import flash.net.; public class cargadorXML extends Sprite { public var cuadro:Sprite = new Sprite(); public var file:FileReference; public var req:URLRequest; public var xml:XML; public var xmlLoader:URLLoader = new URLLoader(); public function cargadorXML() { cuadro.graphics.beginFill(0xFF0000); cuadro.graphics.drawRoundRect(0,0,100,100,10); cuadro.graphics.endFill(); cuadro.addEventListener(MouseEvent.CLICK,browser); addChild(cuadro); } public function browser(e:Event) { file = new FileReference(); file.addEventListener(Event.SELECT,bien); file.browse(); } public function bien(e:Event) { xmlLoader.addEventListener(Event.COMPLETE, loadXML); req=new URLRequest(file.name); xmlLoader.load(req); } public function loadXML(e:Event) { xml=new XML(e.target.data); //xml.name=file.name; trace(xml); } } } when I open a xml file that isnt it the same directory as the swf, it gives me an unfound file error. is there anything I can do? cause for example for mp3 there is an especial class for loading the file, see http://www.flexiblefactory.co.uk/flexible/?p=46 thanks

  • how to get the sql connection

    FS_Setting is a VB class which has all the details of the connections ie: Public Class FS_Setting Public Function Get_RS_Connection() As SqlConnection Try Get_RS_Connection = New SqlConnection("Data Source=***********;User ID=sa;Password=*****;database=*********") Catch ex As System.Exception Throw New System.Exception("Get_RS_Connection Error:" + ex.Message) End Try End Function I need to call the function Get_RS_Connection() in a different class instead of getting the connection all the way again and hard coding....

  • A queue in C using structs and dynamic memory allocation (linked list)

    - by Martin Pugh
    I am tasked with making a queue data structure in C, as a linked list. Our lecturer gave us a large amount of code to implement a stack, but we have to adapt it to create a queue. The code our lecturer gave us ends up not compiling and segfaulting at the exact same point as the code I wrote for the queue. I'm very new to structs, malloc and C in general, so there could be something painfully obvious I've overlooked. Here is the code I am using: #include <stdio.h> #include <stdlib.h> struct node{ int data; //contains the actual data struct node *prev; //pointer to previous node (Closer to front) struct node *next; //pointer to next node (Closer to back) }; typedef struct node *Nodepointer; struct queue{ Nodepointer front; Nodepointer back; }; typedef struct queue *Queuepointer; main(){ Queuepointer myqueue; //create a queue called myqueue init(myqueue); //initialise the queue Nodepointer new = (Nodepointer)malloc(sizeof(struct node)); myqueue->front = new; } int init(Queuepointer q){ q = (Queuepointer)malloc(sizeof(struct queue)); q->front = NULL; q->back = NULL; } The idea is that the queue struct 'contains' the first and last nodes in a queue, and when a node is created, myqueue is updated. However, I cannot even get to that part (pop and push are written but omitted for brevity). The code is segfaulting at the line myqueue->front = new; with the following gdb output: Program received signal SIGSEGV, Segmentation fault. 0x08048401 in main () at queue.c:27 27 myqueue->front = new; Any idea what I'm doing wrong?

  • create board for game with events support

    - by netmajor
    How can I create board for simple game, looks like for chess,but user could dynamically change number of column and rows? In cells I could insert symbol of pawn, like small image or just ellipse or rectangle with fill. This board should have possibility add and remove pawn from cells and move pown from one cell to another. My first idea was Grid. I do it in code behind, but it's hurt to implement events or everything in runtime create board :/ int size = 12; Grid board = new Grid(); board.ShowGridLines = true; for (int i = 0; i < size;i++ ) { board.ColumnDefinitions.Add(new ColumnDefinition()); board.RowDefinitions.Add(new RowDefinition()); } //komputer Rectangle ai = new Rectangle(); ai.Height = 20; ai.Width = 20; ai.AllowDrop = true; ai.Fill = Brushes.Orange; Grid.SetRow(ai, 0); Grid.SetColumn(ai,0); //czlowiek Rectangle hum = new Rectangle(); hum.Height = 20; hum.Width = 20; hum.AllowDrop = true; hum.Fill = Brushes.Green; Grid.SetRow(hum,size); Grid.SetColumn(hum,size); board.Children.Add(ai); board.Children.Add(hum); this.Content = board; It's a way to do this dynamically col and row change in XAML ? It's better way to implement that board create and implement events on move pawn from one cell to another ?

  • Odd performance with C# Asynchronous server socket

    - by The.Anti.9
    I'm working on a web server in C# and I have it running on Asynchronous socket calls. The weird thing is that for some reason, when you start loading pages, the 3rd request is where the browser won't connect. It just keeps saying "Connecting..." and doesn't ever stop. If I hit stop. and then refresh, it will load again, but if I try another time after that it does the thing where it doesn't load again. And it continues in that cycle. I'm not really sure what is making it do that. The code is kind of hacked together from a couple of examples and some old code I had. Any miscellaneous tips would be helpful as well. Heres my little Listener class that handles everything (pastied here. thought it might be easier to read this way) using System; using System.Collections.Generic; using System.Net; using System.Net.Sockets; using System.Text; using System.Threading; namespace irek.Server { public class Listener { private int port; private Socket server; private Byte[] data = new Byte[2048]; static ManualResetEvent allDone = new ManualResetEvent(false); public Listener(int _port) { port = _port; } public void Run() { server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPEndPoint iep = new IPEndPoint(IPAddress.Any, port); server.Bind(iep); Console.WriteLine("Server Initialized."); server.Listen(5); Console.WriteLine("Listening..."); while (true) { allDone.Reset(); server.BeginAccept(new AsyncCallback(AcceptCon), server); allDone.WaitOne(); } } private void AcceptCon(IAsyncResult iar) { allDone.Set(); Socket s = (Socket)iar.AsyncState; Socket s2 = s.EndAccept(iar); SocketStateObject state = new SocketStateObject(); state.workSocket = s2; s2.BeginReceive(state.buffer, 0, SocketStateObject.BUFFER_SIZE, 0, new AsyncCallback(Read), state); } private void Read(IAsyncResult iar) { try { SocketStateObject state = (SocketStateObject)iar.AsyncState; Socket s = state.workSocket; int read = s.EndReceive(iar); if (read > 0) { state.sb.Append(Encoding.ASCII.GetString(state.buffer, 0, read)); if (s.Available > 0) { s.BeginReceive(state.buffer, 0, SocketStateObject.BUFFER_SIZE, 0, new AsyncCallback(Read), state); return; } } if (state.sb.Length > 1) { string requestString = state.sb.ToString(); // HANDLE REQUEST HERE // Temporary response string resp = "<h1>It Works!</h1>"; string head = "HTTP/1.1 200 OK\r\nContent-Type: text/html;\r\nServer: irek\r\nContent-Length:"+resp.Length+"\r\n\r\n"; byte[] answer = Encoding.ASCII.GetBytes(head+resp); // end temp. state.workSocket.BeginSend(answer, 0, answer.Length, SocketFlags.None, new AsyncCallback(Send), state.workSocket); } } catch (Exception) { return; } } private void Send(IAsyncResult iar) { try { SocketStateObject state = (SocketStateObject)iar.AsyncState; int sent = state.workSocket.EndSend(iar); state.workSocket.Shutdown(SocketShutdown.Both); state.workSocket.Close(); } catch (Exception) { } return; } } } And my SocketStateObject: public class SocketStateObject { public Socket workSocket = null; public const int BUFFER_SIZE = 1024; public byte[] buffer = new byte[BUFFER_SIZE]; public StringBuilder sb = new StringBuilder(); }

  • When to use MEF

    - by cmaduro
    I tried Unity and MEF and plain old new. And I am a bit confused as to when exactly you need to use any of these "patterns". Why would I choose to use MEF or Unity if using new is simpler and satisfies my needs. MyObject a = new MyObject(); In other words, what needs justify the use of MEF or Unity?

  • Invert linear linked list

    - by ArtWorkAD
    Hi, a linear linked list is a set of nodes. This is how a node is defined (to keep it easy we do not distinguish between node an list): class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } public String toString(){ if(this.link != null){ return this.data.toString() + this.link.toString(); }else{ return this.data.toString() ; } } public void inc(){ this.data = new Integer((Integer)this.data + 1); } public void lappend(Node list){ Node child = this.link; while(child != null){ child = child.link; } child.link = list; } public Node copy(){ if(this.link != null){ return new Node(new Integer((Integer)this.data), this.link.copy()); }else{ return new Node(new Integer((Integer)this.data), null); } } public Node invert(){ Node child = this.link; while(child != null){ child = child.link; } child.link = this;.... } } I am able to make a deep copy of the list. Now I want to invert the list so that the first node is the last and the last the first. The inverted list has to be a deep copy. I started developing the invert function but I am not sure. Any Ideas? Update: Maybe there is a recursive way since the linear linked list is a recursive data structure. I would take the first element, iterate through the list until I get to a node that has no child and append the first element, I would repeat this for the second, third....

  • Android animation's first frame is applied too early on ImageView

    - by Robert
    I have the following View setup in one of my Activities: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/photoLayout" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/photoImageView" android:src="@drawable/backyardPhoto" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:scaleType="centerInside" android:padding="45dip" > </ImageView> </LinearLayout> Without an animation set, this displays just fine. However I want to display a very simple animation. So in my Activity's onStart override, I have the following: @Override public void onStart() { super.onStart(); mPhotoImageView = (ImageView) findViewById(R.id.photoImageView); float offset = -25; int top = mPhotoImageView.getTop(); TranslateAnimation anim1 = new TranslateAnimation( Animation.ABSOLUTE, 0, Animation.ABSOLUTE, 0, Animation.ABSOLUTE, top, Animation.ABSOLUTE, offset); anim1.setInterpolator(new AnticipateInterpolator()); anim1.setDuration(1500); anim1.setStartOffset(5000); TranslateAnimation anim2 = new TranslateAnimation( Animation.ABSOLUTE, 0, Animation.ABSOLUTE, 0, Animation.ABSOLUTE, offset, Animation.ABSOLUTE, top); anim2.setInterpolator(new BounceInterpolator()); anim2.setDuration(3500); anim2.setStartOffset(6500); mBouncingAnimation = new AnimationSet(false); mBouncingAnimation.addAnimation(anim1); mBouncingAnimation.addAnimation(anim2); mPhotoImageView.setAnimation(mBouncingAnimation); } The problem is that when the Activity displays for the first time, the initial position of the photo is not in the center of the screen with padding around. It seems like the first frame of the animation is loaded already. Only after the animation is completed, does the photoImageView "snap" back to the intended location. I've looked and looked and could not find how to avoid this problem. I want the photoImageView to start in the center of the screen, and then the animation to happen, and return it to the center of the screen. The animation should happen by itself without interaction from the user.

  • Incremental PCA

    - by smichak
    Hi, Lately, I've been looking into an implementation of an incremental PCA algorithm in python - I couldn't find something that would meet my needs so I did some reading and implemented an algorithm I found in some paper. Here is the module's code - the relevant paper on which it is based is mentioned in the module's documentation. I would appreciate any feedback from people who are interested in this.

Martin "Incremental Eigenalysis for Classification" which appeared in British Machine Vision Conference, volume 1, pages 286-295, September 1998. Principal components are updated sequentially as new observations are introduced. Each new observation (x) is projected on the eigenspace spanned by the current principal components (U) and the residual vector (r = x - U(U.T*x)) is used as a new principal component (U' = [U r]). The new principal components are then rotated by a rotation matrix (R) whose columns are the eigenvectors of the transformed covariance matrix (D=U'.T*C*U) to yield p + 1 principal components. From those, only the first p are selected.

  • ObjectContext disposed puzzle

    - by jaklucky
    Hi, I have the follwing method. public List<MyEntity> GetMyEntities(MyObjectContext objCtx) { using(MyObjectContext ctx = objCtx ?? new MyObjectContext()) { retun ctx.MyEntities.ToList(); } } The idea is, user of this method can pass in the objectcontext if they have. If not then a new objectcontext will be created. If I am passing an object context to it, then it is getting disposed after the method is done. I was expecting only "ctx" variable gets disposed. If I write a small app, to know the using and dispose mechanism. It is acting differently. class TestClass : IDisposable { public int Number { get; set; } public string Str { get; set; } public ChildClass Child { get; set; } #region IDisposable Members public void Dispose() { Console.WriteLine("Disposed is called"); } #endregion } class ChildClass : IDisposable { public string StrChild { get; set; } #region IDisposable Members public void Dispose() { Console.WriteLine("Child Disposed is called"); } #endregion } class Program { static void Main(string[] args) { TestClass test = null; test = new TestClass(); test.Child = new ChildClass(); using (TestClass test1 = test ?? new TestClass()) { test1.Number = 1; test1.Str = "hi"; test1.Child.StrChild = "Child one"; test1.Child.Dispose(); } test.Str = "hi"; test.Child.StrChild = "hi child"; Console.ReadLine(); } } In this example, "test1"gets disposed but not "test".

  • Rails "NoMethodError" with sub-resources

    - by Tchock
    Hi. I'm a newbie Rails developer who is getting the following error when trying to access the 'new' action on my CityController: undefined method `cities_path' for #<#<Class:0x104608c18>:0x104606f08> Extracted source (around line #2): 1: <h1>New City</h1> 2: <%= form_for(@city) do |f| %> 3: <%= f.error_messages %> 4: 5: <div class="field"> As some background, I have a State model with many Cities. I'm getting this error after clicking on the following link coming from a State show page: <p>Add a city: <%= link_to "Add city", new_state_city_path(@state) %></p> When I run 'rake:routes' it says this is a legit route... For more background, here is the CityController 'new' action: def new @city = City.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @city } end end Here is the (complete) form in the view: <%= form_for(@city) do |f| %> <%= f.error_messages %> <div class="field"> <%= f.label :name %><br /> <%= f.text_field :name %> </div> <div class="actions"> <%= f.submit %> </div> <% end %> This initially made me think that it's a resources/routes issue since it came back with a mention of 'cities_path' (in fact, that's what another person posting to Stack Overflow had wrong (http://stackoverflow.com/questions/845315/rails-error-nomethoderror-my-first-ruby-app). However, that doesn't seem to be the case from what I can see. Here are how my resources look in my routes file: resources :states do resources :cities end I can get it working when they are not sub-resources, but I really need to keep them as sub-resources for my future plans with the app. Any help would be very much appreciated, since I've been racking my brains on this for more hours than I would care to admit... Thanks! (Not sure this matters at all, but I'm running the very latest version of Rails 3 beta2).

  • split string error in a compiled VB.NET class

    - by Andy Payne
    I'm having some trouble compiling some VB code I wrote to split a string based on a set of predefined delimeters (comma, semicolon, colon, etc). I have successfully written some code that can be loaded inside a custom VB component (I place this code inside a VB.NET component in a plug-in called Grasshopper) and everything works fine. For instance, let's say my incoming string is "123,456". When I feed this string into the VB code I wrote, I get a new list where the first value is "123" and the second value is "456". However, I have been trying to compile this code into it's own class so I can load it inside Grasshopper separately from the standard VB component. When I try to compile this code, it isn't separating the string into a new list with two values. Instead, I get a message that says "System.String []". Do you guys see anything wrong in my compile code? You can find an screenshot image of my problem at the following link: click to see image This is the VB code for the compiled class: Public Class SplitString Inherits GH_Component Public Sub New() MyBase.New("Split String", "Split", "Splits a string based on delimeters", "FireFly", "Serial") End Sub Public Overrides ReadOnly Property ComponentGuid() As System.Guid Get Return New Guid("3205caae-03a8-409d-8778-6b0f8971df52") End Get End Property Protected Overrides ReadOnly Property Internal_Icon_24x24() As System.Drawing.Bitmap Get Return My.Resources.icon_splitstring End Get End Property Protected Overrides Sub RegisterInputParams(ByVal pManager As Grasshopper.Kernel.GH_Component.GH_InputParamManager) pManager.Register_StringParam("String", "S", "Incoming string separated by a delimeter like a comma, semi-colon, colon, or forward slash", False) End Sub Protected Overrides Sub RegisterOutputParams(ByVal pManager As Grasshopper.Kernel.GH_Component.GH_OutputParamManager) pManager.Register_StringParam("Tokenized Output", "O", "Tokenized Output") End Sub Protected Overrides Sub SolveInstance(ByVal DA As Grasshopper.Kernel.IGH_DataAccess) Dim myString As String DA.GetData(0, myString) myString = myString.Replace(",", "|") myString = myString.Replace(":", "|") myString = myString.Replace(";", "|") myString = myString.Replace("/", "|") myString = myString.Replace(")(", "|") myString = myString.Replace("(", String.Empty) myString = myString.Replace(")", String.Empty) Dim parts As String() = myString.Split("|"c) DA.SetData(0, parts) End Sub End Class This is the custom VB code I created inside Grasshopper: Private Sub RunScript(ByVal myString As String, ByRef A As Object) myString = myString.Replace(",", "|") myString = myString.Replace(":", "|") myString = myString.Replace(";", "|") myString = myString.Replace("/", "|") myString = myString.Replace(")(", "|") myString = myString.Replace("(", String.Empty) myString = myString.Replace(")", String.Empty) Dim parts As String() = myString.Split("|"c) A = parts End Sub ' ' End Class

  • Making swap faster, easier to use and exception-safe

    - by FredOverflow
    I could not sleep last night and started thinking about std::swap. Here is the familiar C++98 version: template <typename T> void swap(T& a, T& b) { T c(a); a = b; b = c; } If a user-defined class Foo uses external ressources, this is inefficient. The common idiom is to provide a method void Foo::swap(Foo& other) and a specialization of std::swap<Foo>. Note that this does not work with class templates since you cannot partially specialize a function template, and overloading names in the std namespace is illegal. The solution is to write a template function in one's own namespace and rely on argument dependent lookup to find it. This depends critically on the client to follow the "using std::swap idiom" instead of calling std::swap directly. Very brittle. In C++0x, if Foo has a user-defined move constructor and a move assignment operator, providing a custom swap method and a std::swap<Foo> specialization has little to no performance benefit, because the C++0x version of std::swap uses efficient moves instead of copies: #include <utility> template <typename T> void swap(T& a, T& b) { T c(std::move(a)); a = std::move(b); b = std::move(c); } Not having to fiddle with swap anymore already takes a lot of burden away from the programmer. Current compilers do not generate move constructors and move assignment operators automatically yet, but as far as I know, this will change. The only problem left then is exception-safety, because in general, move operations are allowed to throw, and this opens up a whole can of worms. The question "What exactly is the state of a moved-from object?" complicates things further. Then I was thinking, what exactly are the semantics of std::swap in C++0x if everything goes fine? What is the state of the objects before and after the swap? Typically, swapping via move operations does not touch external resources, only the "flat" object representations themselves. So why not simply write a swap template that does exactly that: swap the object representations? #include <cstring> template <typename T> void swap(T& a, T& b) { unsigned char c[sizeof(T)]; memcpy( c, &a, sizeof(T)); memcpy(&a, &b, sizeof(T)); memcpy(&b, c, sizeof(T)); } This is as efficient as it gets: it simply blasts through raw memory. It does not require any intervention from the user: no special swap methods or move operations have to be defined. This means that it even works in C++98 (which does not have rvalue references, mind you). But even more importantly, we can now forget about the exception-safety issues, because memcpy never throws. I can see two potential problems with this approach: First, not all objects are meant to be swapped. If a class designer hides the copy constructor or the copy assignment operator, trying to swap objects of the class should fail at compile-time. We can simply introduce some dead code that checks whether copying and assignment are legal on the type: template <typename T> void swap(T& a, T& b) { if (false) // dead code, never executed { T c(a); // copy-constructible? a = b; // assignable? } unsigned char c[sizeof(T)]; std::memcpy( c, &a, sizeof(T)); std::memcpy(&a, &b, sizeof(T)); std::memcpy(&b, c, sizeof(T)); } Any decent compiler can trivially get rid of the dead code. (There are probably better ways to check the "swap conformance", but that is not the point. What matters is that it's possible). Second, some types might perform "unusual" actions in the copy constructor and copy assignment operator. For example, they might notify observers of their change. I deem this a minor issue, because such kinds of objects probably should not have provided copy operations in the first place. Please let me know what you think of this approach to swapping. Would it work in practice? Would you use it? Can you identify library types where this would break? Do you see additional problems? Discuss!

  • SQLite Modify Column

    - by Nathan
    I need to modify a column in a SQLite database but I have to do it programatically due to the database already being in production. From my research I have found that in order to do this I must do the following. Create a new table with new schema Copy data from old table to new table Drop old table Rename new table to old tables name That seems like a ridiculous amount of work for something that should be relatively easy. Is there not an easier way? All I need to do is change a constraint on a existing column and give it a default value.

  • Android Augmented Reality

    - by Azooz Totti
    I'm working on my first Android Augmented Reality application. The application works pretty good if the ARActivity runs as the first class (android.intent.category.LAUNCHER) in the manifest file. But when I added a splash screen which means the ARActivity will be the second to run(android.intent.category.DEFAULT), the camera seems not detecting the marker. I believe the problem is all in the manifest file. Any suggestions ?

  • improving conversions to binary and back in C#

    - by Saad Imran.
    I'm trying to write a general purpose socket server for a game I'm working on. I know I could very well use already built servers like SmartFox and Photon, but I wan't to go through the pain of creating one myself for learning purposes. I've come up with a BSON inspired protocol to convert the the basic data types, their arrays, and a special GSObject to binary and arrange them in a way so that it can be put back together into object form on the client end. At the core, the conversion methods utilize the .Net BitConverter class to convert the basic data types to binary. Anyways, the problem is performance, if I loop 50,000 times and convert my GSObject to binary each time it takes about 5500ms (the resulting byte[] is just 192 bytes per conversion). I think think this would be way too slow for an MMO that sends 5-10 position updates per second with a 1000 concurrent users. Yes, I know it's unlikely that a game will have a 1000 users on at the same time, but like I said earlier this is supposed to be a learning process for me, I want to go out of my way and build something that scales well and can handle at least a few thousand users. So yea, if anyone's aware of other conversion techniques or sees where I'm loosing performance I would appreciate the help. GSBitConverter.cs This is the main conversion class, it adds extension methods to main datatypes to convert to the binary format. It uses the BitConverter class to convert the base types. I've shown only the code to convert integer and integer arrays, but the rest of the method are pretty much replicas of those two, they just overload the type. public static class GSBitConverter { public static byte[] ToGSBinary(this short value) { return BitConverter.GetBytes(value); } public static byte[] ToGSBinary(this IEnumerable<short> value) { List<byte> bytes = new List<byte>(); short length = (short)value.Count(); bytes.AddRange(length.ToGSBinary()); for (int i = 0; i < length; i++) bytes.AddRange(value.ElementAt(i).ToGSBinary()); return bytes.ToArray(); } public static byte[] ToGSBinary(this bool value); public static byte[] ToGSBinary(this IEnumerable<bool> value); public static byte[] ToGSBinary(this IEnumerable<byte> value); public static byte[] ToGSBinary(this int value); public static byte[] ToGSBinary(this IEnumerable<int> value); public static byte[] ToGSBinary(this long value); public static byte[] ToGSBinary(this IEnumerable<long> value); public static byte[] ToGSBinary(this float value); public static byte[] ToGSBinary(this IEnumerable<float> value); public static byte[] ToGSBinary(this double value); public static byte[] ToGSBinary(this IEnumerable<double> value); public static byte[] ToGSBinary(this string value); public static byte[] ToGSBinary(this IEnumerable<string> value); public static string GetHexDump(this IEnumerable<byte> value); } Program.cs Here's the the object that I'm converting to binary in a loop. class Program { static void Main(string[] args) { GSObject obj = new GSObject(); obj.AttachShort("smallInt", 15); obj.AttachInt("medInt", 120700); obj.AttachLong("bigInt", 10900800700); obj.AttachDouble("doubleVal", Math.PI); obj.AttachStringArray("muppetNames", new string[] { "Kermit", "Fozzy", "Piggy", "Animal", "Gonzo" }); GSObject apple = new GSObject(); apple.AttachString("name", "Apple"); apple.AttachString("color", "red"); apple.AttachBool("inStock", true); apple.AttachFloat("price", (float)1.5); GSObject lemon = new GSObject(); apple.AttachString("name", "Lemon"); apple.AttachString("color", "yellow"); apple.AttachBool("inStock", false); apple.AttachFloat("price", (float)0.8); GSObject apricoat = new GSObject(); apple.AttachString("name", "Apricoat"); apple.AttachString("color", "orange"); apple.AttachBool("inStock", true); apple.AttachFloat("price", (float)1.9); GSObject kiwi = new GSObject(); apple.AttachString("name", "Kiwi"); apple.AttachString("color", "green"); apple.AttachBool("inStock", true); apple.AttachFloat("price", (float)2.3); GSArray fruits = new GSArray(); fruits.AddGSObject(apple); fruits.AddGSObject(lemon); fruits.AddGSObject(apricoat); fruits.AddGSObject(kiwi); obj.AttachGSArray("fruits", fruits); Stopwatch w1 = Stopwatch.StartNew(); for (int i = 0; i < 50000; i++) { byte[] b = obj.ToGSBinary(); } w1.Stop(); Console.WriteLine(BitConverter.IsLittleEndian ? "Little Endian" : "Big Endian"); Console.WriteLine(w1.ElapsedMilliseconds + "ms"); } Here's the code for some of my other classes that are used in the code above. Most of it is repetitive.
