• Weird output as the numbers get bigger in Fibonacci sequence

  - by Jon

  I noticed in my fibonacci sequence that I'm getting negative numbers after a certain point. Does this have to do with the limited range of "int"? or is there something wrong with my code? Here is the code: using std::cout; int main() { int n = 50, f1 = 0, f2 = 1, fn = 0, i = 0; cout << "0 "; for (i = 0; i < n; i++) { fn = f1 + f2; f2 = f1; f1 = fn; cout << fn << " "; }

• Linq - Grouping where items fall in multiple groups?

  - by PirateKitten

  Is it possible using Linq to create a group where items fall into more than one group? Using the following trivial example: public class Data { public string ID; public int From; public int To; } And this list: List<Data> data = new List<Data>() { new Data() { ID = "A", From = 1, To = 3 }, // Call this A new Data() { ID = "B", From = 1, To = 2 }, // Call this B new Data() { ID = "C", From = 2, To = 3 } // Call this C }; I'd like to group by each possible integer in the ranges From and To (though instead of finding the min + max I could supply the query with the range I want, for example 1 to 3), and in each group would be a reference to the Data instance where the grouping int fits in its range. Hard to explain, easier to show each group and the instances I'd expect in each: [Group 1] 1 - A, B [Group 2] 2 - A, B, C [Group 3] 3 - A, C Is this possible? Or must groups be mutually exclusive?

• Cutting Row with Data and moving to different sheet VBA

  - by user3709645

  I'm trying to cut a row that has the specified cell blank and then paste it into another sheet in the same workbook. My coding works fine to delete the row but everything I've tried to cut and paste keeps giving me errors. Here's the working code that deletes the rows: Sub Remove() 'Remove No Denovo &/or No Peak Seq Dim n As Long Dim nLastRow As Long Dim nFirstRow As Long Dim lastRow As Integer ActiveSheet.UsedRange Set r = ActiveSheet.UsedRange nLastRow = r.rows.Count + r.Row - 1 nFirstRow = r.Row For n = nLastRow To nFirstRow Step -1 If Cells(n, "G") = "" Then Cells(n, "G").EntireRow.Delete Next n End Sub Thanks for any help!

• concatenation output problem (toString Array) - java

  - by dowln

  Hello, I am trying to display the output as "1(10) 2(23) 3(29)" but instead getting output as "1 2 3 (10)(23)(29)". I would be grateful if someone could have a look the code and possible help me. I don't want to use arraylist. the code this // int[] Groups = {10, 23, 29}; in the constructor public String toString() { String tempStringB = ""; String tempStringA = " "; String tempStringC = " "; for (int x = 1; x<=3; x+=1) { tempStringB = tempStringB + x + " "; } for(int i = 0; i < Group.length;i++) { tempStringA = tempStringA + "(" + Groups[i] + ")"; } tempStringC = tempStringB + tempStringA; return tempStringC; }

• Generics not so generic !!

  - by Aymen

  Hi I tried to implement a generic binary search algorithm in scala. Here it is : type Ord ={ def <(x:Any):Boolean def >(x:Any):Boolean } def binSearch[T <: Ord ](x:T,start:Int,end:Int,t:Array[T]):Boolean = { if (start > end) return false val pos = (start + end ) / 2 if(t(pos)==x) true else if (t(pos) < x) binSearch(x,pos+1,end,t) else binSearch(x,start,pos-1,t) } everything is OK until I tried to actually use it (xD) : binSearch(3,0,4,Array(1,2,5,6)) the compiler is pretending that Int not a member of Ord, well what shall I do to solve this ? Thanks

• C++ file including C header file

  - by fdeslaur

  I need to include a C header file in my C++ project but g++ throws "not declared in this scope" errors. I read that i need to use extern "C" keyword to fix it but it didn't seem to work for me. Here is a dummy example triggering this error. main.cpp: #include <iostream> extern "C" { #include "includedFile.h" } int main() { int a = 2; int b = 1212; std::cout<< "Hello World!\n"; return 0; } includedFile.h #include <stdint.h> enum TypeOfEnum { ONE, TWO, THREE, FOUR = INT32_MAX, }; The error thrown is : $> g++ main.cpp In file included from main.cpp:4:0: includedFile.h:7:9: error: ‘INT32_MAX’ was not declared in this scope FOUR = INT32_MAX, I saw on this post that I may need #define __STDC_LIMIT_MACROS without any success. Any help is welcome!

• any other way to find char array length?

  - by user2785137

  public static int getLenth(char[] t) { int i=0; int count=0; try { while(t[i]!='\0') { ++count; i++; } return count; } catch(ArrayIndexOutOfBoundsException aiobe) { return count; } } This method returns length of charArray. But my question is, is there is some other "ways" to find the length of charArray without using this try, catch statements & all ?? Thanks in advance :)

• C++ problem with assimp 3D model loader

  - by Brendan Webster

  In my game I have model loading functions for Assimp model loading library. I can load the model and render it, but the model displays incorrectly. The models load in as if they were using a seperate projection matrix. I have looked over my code over and over again, but I probably keep on missing the obvious reason why this is happening. Here is an image of my game: It's simply a 6 sided cube, but it's off big time! Here are my code snippets for rendering the cube to the screen: void C_MediaLoader::display(void) { float tmp; glTranslatef(0,0,0); // rotate it around the y axis glRotatef(angle,0.f,0.f,1.f); glColor4f(1,1,1,1); // scale the whole asset to fit into our view frustum tmp = scene_max.x-scene_min.x; tmp = aisgl_max(scene_max.y - scene_min.y,tmp); tmp = aisgl_max(scene_max.z - scene_min.z,tmp); tmp = (1.f / tmp); glScalef(tmp/5, tmp/5, tmp/5); // center the model //glTranslatef( -scene_center.x, -scene_center.y, -scene_center.z ); // if the display list has not been made yet, create a new one and // fill it with scene contents if(scene_list == 0) { scene_list = glGenLists(1); glNewList(scene_list, GL_COMPILE); // now begin at the root node of the imported data and traverse // the scenegraph by multiplying subsequent local transforms // together on GL's matrix stack. recursive_render(scene, scene->mRootNode); glEndList(); } glCallList(scene_list); } void C_MediaLoader::recursive_render (const struct aiScene *sc, const struct aiNode* nd) { unsigned int i; unsigned int n = 0, t; struct aiMatrix4x4 m = nd->mTransformation; // update transform aiTransposeMatrix4(&m); glPushMatrix(); glMultMatrixf((float*)&m); // draw all meshes assigned to this node for (; n < nd->mNumMeshes; ++n) { const struct aiMesh* mesh = scene->mMeshes[nd->mMeshes[n]]; apply_material(sc->mMaterials[mesh->mMaterialIndex]); if(mesh->mNormals == NULL) { glDisable(GL_LIGHTING); } else { glEnable(GL_LIGHTING); } for (t = 0; t < mesh->mNumFaces; ++t) { const struct aiFace* face = &mesh->mFaces[t]; GLenum face_mode; switch(face->mNumIndices) { case 1: face_mode = GL_POINTS; break; case 2: face_mode = GL_LINES; break; case 3: face_mode = GL_TRIANGLES; break; default: face_mode = GL_POLYGON; break; } glBegin(face_mode); for(i = 0; i < face->mNumIndices; i++) { int index = face->mIndices[i]; if(mesh->mColors[0] != NULL) glColor4fv((GLfloat*)&mesh->mColors[0][index]); if(mesh->mNormals != NULL) glNormal3fv(&mesh->mNormals[index].x); glVertex3fv(&mesh->mVertices[index].x); } glEnd(); } } // draw all children for (n = 0; n < nd->mNumChildren; ++n) { recursive_render(sc, nd->mChildren[n]); } glPopMatrix(); } Sorry there is so much code to look through, but I really cannot find the problem, and I would love to have help.

• FrameBuffer Render to texture not working all the way

  - by brainydexter

  I am learning to use Frame Buffer Objects. For this purpose, I chose to render a triangle to a texture and then map that to a quad. When I render the triangle, I clear the color to something blue. So, when I render the texture on the quad from fbo, it only renders everything blue, but doesn't show up the triangle. I can't seem to figure out why this is happening. Can someone please help me out with this ? I'll post the rendering code here, since glCheckFramebufferStatus doesn't complain when I setup the FBO. I've pasted the setup code at the end. Here is my rendering code: void FrameBufferObject::Render(unsigned int elapsedGameTime) { glBindFramebuffer(GL_FRAMEBUFFER, m_FBO); glClearColor(0.0, 0.6, 0.5, 1); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // adjust viewport and projection matrices to texture dimensions glPushAttrib(GL_VIEWPORT_BIT); glViewport(0,0, m_FBOWidth, m_FBOHeight); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0, m_FBOWidth, 0, m_FBOHeight, 1.0, 100.0); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); DrawTriangle(); glPopAttrib(); // setting FrameBuffer back to window-specified Framebuffer glBindFramebuffer(GL_FRAMEBUFFER, 0); //unbind // back to normal viewport and projection matrix //glViewport(0, 0, 1280, 768); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(45.0, 1.33, 1.0, 1000.0); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glClearColor(0, 0, 0, 0); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); render(elapsedGameTime); } void FrameBufferObject::DrawTriangle() { glPushMatrix(); glBegin(GL_TRIANGLES); glColor3f(1, 0, 0); glVertex2d(0, 0); glVertex2d(m_FBOWidth, 0); glVertex2d(m_FBOWidth, m_FBOHeight); glEnd(); glPopMatrix(); } void FrameBufferObject::render(unsigned int elapsedTime) { glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, m_TextureID); glPushMatrix(); glTranslated(0, 0, -20); glBegin(GL_QUADS); glColor4f(1, 1, 1, 1); glTexCoord2f(1, 1); glVertex3f(1,1,1); glTexCoord2f(0, 1); glVertex3f(-1,1,1); glTexCoord2f(0, 0); glVertex3f(-1,-1,1); glTexCoord2f(1, 0); glVertex3f(1,-1,1); glEnd(); glPopMatrix(); glBindTexture(GL_TEXTURE_2D, 0); glDisable(GL_TEXTURE_2D); } void FrameBufferObject::Initialize() { // Generate FBO glGenFramebuffers(1, &m_FBO); glBindFramebuffer(GL_FRAMEBUFFER, m_FBO); // Add depth buffer as a renderbuffer to fbo // create depth buffer id glGenRenderbuffers(1, &m_DepthBuffer); glBindRenderbuffer(GL_RENDERBUFFER, m_DepthBuffer); // allocate space to render buffer for depth buffer glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH_COMPONENT, m_FBOWidth, m_FBOHeight); // attaching renderBuffer to FBO // attach depth buffer to FBO at depth_attachment glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, m_DepthBuffer); // Adding a texture to fbo // Create a texture glGenTextures(1, &m_TextureID); glBindTexture(GL_TEXTURE_2D, m_TextureID); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA8, m_FBOWidth, m_FBOHeight, 0, GL_RGBA, GL_UNSIGNED_BYTE, 0); // onlly allocating space glBindTexture(GL_TEXTURE_2D, 0); // attach texture to FBO glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, m_TextureID, 0); // Check FBO Status if( glCheckFramebufferStatus(GL_FRAMEBUFFER) != GL_FRAMEBUFFER_COMPLETE) std::cout << "\n Error:: FrameBufferObject::Initialize() :: FBO loading not complete \n"; // switch back to window system Framebuffer glBindFramebuffer(GL_FRAMEBUFFER, 0); } Thanks!

• Child transforms problem when loading 3DS models using assimp

  - by MhdSyrwan

  I'm trying to load a textured 3d model into my scene using assimp model loader. The problem is that child meshes are not situated correctly (they don't have the correct transformations). In brief: all the mTansform matrices are identity matrices, why would that be? I'm using this code to render the model: void recursive_render (const struct aiScene *sc, const struct aiNode* nd, float scale) { unsigned int i; unsigned int n=0, t; aiMatrix4x4 m = nd->mTransformation; m.Scaling(aiVector3D(scale, scale, scale), m); // update transform m.Transpose(); glPushMatrix(); glMultMatrixf((float*)&m); // draw all meshes assigned to this node for (; n < nd->mNumMeshes; ++n) { const struct aiMesh* mesh = scene->mMeshes[nd->mMeshes[n]]; apply_material(sc->mMaterials[mesh->mMaterialIndex]); if (mesh->HasBones()){ printf("model has bones"); abort(); } if(mesh->mNormals == NULL) { glDisable(GL_LIGHTING); } else { glEnable(GL_LIGHTING); } if(mesh->mColors[0] != NULL) { glEnable(GL_COLOR_MATERIAL); } else { glDisable(GL_COLOR_MATERIAL); } for (t = 0; t < mesh->mNumFaces; ++t) { const struct aiFace* face = &mesh->mFaces[t]; GLenum face_mode; switch(face->mNumIndices) { case 1: face_mode = GL_POINTS; break; case 2: face_mode = GL_LINES; break; case 3: face_mode = GL_TRIANGLES; break; default: face_mode = GL_POLYGON; break; } glBegin(face_mode); for(i = 0; i < face->mNumIndices; i++)// go through all vertices in face { int vertexIndex = face->mIndices[i];// get group index for current index if(mesh->mColors[0] != NULL) Color4f(&mesh->mColors[0][vertexIndex]); if(mesh->mNormals != NULL) if(mesh->HasTextureCoords(0))//HasTextureCoords(texture_coordinates_set) { glTexCoord2f(mesh->mTextureCoords[0][vertexIndex].x, 1 - mesh->mTextureCoords[0][vertexIndex].y); //mTextureCoords[channel][vertex] } glNormal3fv(&mesh->mNormals[vertexIndex].x); glVertex3fv(&mesh->mVertices[vertexIndex].x); } glEnd(); } } // draw all children for (n = 0; n < nd->mNumChildren; ++n) { recursive_render(sc, nd->mChildren[n], scale); } glPopMatrix(); } What's the problem in my code ? I've added some code to abort the program if there's any bone in the meshes, but the program doesn't abort, this means : no bones, is that normal? if (mesh->HasBones()){ printf("model has bones"); abort(); } Note: I am using openGL & SFML & assimp

• Problems extracting information from RSS feed description field

  - by Graeme

  Hi, I've built an iPhone application using the parsing code from the TopSongs sample iPhone application. I've hit a problem though - the feed I'm trying to parse data from doesn't have a separate field for every piece of information (i.e. if it was for a feed about dogs, all the information such as dog type, dog age and dog price is contained in the feed. However, the TopSongs app relies on information having its own tags, so instead of using it uses and . So my question is this. How do I extract this information from the description field so that it can be parsed using the TopSongs parser? Can you somehow extract the dog age, price and type information using Yahoo Pipes and use that RSS feed for the feed? Or is there code that I can add to do it in application? Update: To view the code of my application parser (based on the TopSongs Core Data Apple provided application, see below. Here's a sample of one item from the the actual RSS feed I'm using (the description is longer, and has status,size, and a couple of other fields, but they're all formatted the same.: <item> <title>MOE, MARGRET STREET</title> <description> <b>District/Region:</b>&nbsp;REGION 09</br><b>Location:</b>&nbsp;MOE</br><b>Name:</b>&nbsp;MARGRET STREET</br></description> <pubDate>Thu,11 Mar 2010 05:43:03 GMT</pubDate> <guid>1266148</guid> </item> /* File: iTunesRSSImporter.m Abstract: Downloads, parses, and imports the iTunes top songs RSS feed into Core Data.

• Developer Dashboard in SharePoint 2010

  - by jcortez

  Introducing the Developer Dashboard As a SharePoint developer (or IT Professional), how many times have you had the pleasure of figuring out why a particular page on your site is taking too long to render? I'm sure one of the techniques you have employed in troubleshooting is the process of elimination - removing individual web parts from the page hoping to identify which web part is misbehaving. One of the new features of SharePoint 2010 is the Developer Dashboard. This dashboard provides tracing and performance information that can be useful when you are trying to troubleshoot pages that are loading too slow. The Developer Dashboard is turned off by default and I'll go over 3 different ways to display it. Here is a screenshot of what the Developer Dashboard looks like when displayed at the bottom of the page:   You can see on the left side the different events that fired during the page processing pipeline and how long these events took. This is where you will see individual web parts being processed and how long it took to complete (obviously the kind of processing depends on what the web part does). On the right side you would see the different database calls issued through the SharePoint Object Model to process the page. You will notice that each of these database queries are actually a hyperlink and clicking on it displays a pop-up window that shows the actual SQL Query Text, the Call Stack that triggered the database call, and the IO statistics of that query. Enabling the Developer Dashboard Option 1: Managed Code   The Developer Dashboard is a farm-wide setting and the code above won't work if it is used within a web part hosted on any non-Central Admin site. The SPDeveloperDashboardLevel enum has three possible values: On, Off, and OnDemand. Setting it to On will always display the Developer Dashboard at the bottom of the page. Setting it Off will hide the Developer Dashboard. Setting it to OnDemand will add an icon at the top right corner of the page (see screenshot below) where a Site Collection Admin can toggle the display of the Developer Dashboard for a particular site collection. In my opinion, OnDemand is the best setting when troubleshooting a page or during development since a Site Collection Admin can turn it on or off and for a particular site only. The first cool thing about this is that the Site Collection Admin that turned it on will be the only one to see the Developer Dashboard output. Everyday users won't see the Developer Dashboard output even if it was turned on by a Site Collection Admin. If you need more flexibility on who gets to see the Developer Dashboard output, you can set the SPDeveloperDashboardSettings.RequiredPermissions to control which group of users will have the permission to see the output. Option 2: Using stsadm Using stsadm, you can run the following command to configure the Developer Dashboard: STSADM –o setproperty –pn developer-dashboard –pv OnDemand To successfully execute this command, be sure you that are running as a Farm Admin. Option 3: Using PowerShell For all scripts in SharePoint 2010, I prefer writing them as PowerShell scripts. Though the stsadm command is less verbose, the PowerShell equivalent is pretty straightforward and uses the SharePoint Object Model: You can of course parameterized the value that gets assigned to the DisplayLevel property so you can turn it On, Off or OnDemand depending on the parameter. Events and the Developer Dashboard  Now, don't assume that all the code inside your web part or page will show up in the Developer Dashboard complete with all the great troubleshooting information. Only a finite set of events are monitored by default (for a web part it will events in the base web part class). Let's say you have a click event that could take some time, for example a web service call. And you want to include troubleshooting information for this event in the Developer Dashboard. Enter SPMonitoredScope which is also a new feature in SharePoint 2010. In SharePoint 2010, everything is executed within a "Monitored Scope". And each scope has a set of "Monitors" that measures and counts calls and timings which appears in the Developer Dashboard. Below is an example on how to get your custom code to get included in the Developer Dashboard by wrapping it inside a new monitored scope: The code above would include your new scope "My long web service call" into the Developer Dashboard and would log the time it took to complete processing. In my opinion, wrapping your custom code in a SPMonitoredScope is a SharePoint development best practice since it provides you visibility and a better understanding on the performance of your components.

• How to fix Monogame WP8 Touch Position bug?

  - by Moses Aprico

  Normally below code will result in X:Infinity, Y:Infinity TouchCollection touchState = TouchPanel.GetState(); foreach (TouchLocation t in touchState) { if (t.State == TouchLocationState.Pressed) { vb.ButtonTouched((int)t.Position.X, (int)t.Position.Y); } } Then, I followed this https://github.com/mono/MonoGame/issues/1046 and added below code at the first line in update method. (I still don't know how it's worked, but it fixed the problem) if (_firstUpdate) { typeof(Microsoft.Xna.Framework.Input.Touch.TouchPanel).GetField("_touchScale",System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Static).SetValue(null, Vector2.One); _firstUpdate = false; } And then, when I randomly testing something, there are several area that won't read the user touch. The tile with the purple dude is the area which won't receive user input (It don't even detect "Pressed", the TouchCollection.Count = 0) Any idea how to fix this? UPDATE 1 : The second attempt in recompiling The difference is weird. Dunno why the consistent clickable area is just 2/3 area to the left UPDATE 2 : After trying to rotate to landscape and back to portrait to randomly testing, then the outcome become :

• SQL SERVER – Server Side Paging in SQL Server 2011 – A Better Alternative

  - by pinaldave

  Ranking has improvement considerably from SQL Server 2000 to SQL Server 2005/2008 to SQL Server 2011. Here is the blog article where I wrote about SQL Server 2005/2008 paging method SQL SERVER – 2005 T-SQL Paging Query Technique Comparison (OVER and ROW_NUMBER()) – CTE vs. Derived Table. One can achieve this using OVER clause and ROW_NUMBER() function. Now SQL Server 2011 has come up with the new Syntax for paging. Here is how one can easily achieve it. USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 5 SELECT * FROM Sales.SalesOrderDetail ORDER BY SalesOrderDetailID OFFSET @PageNumber*@RowsPerPage ROWS FETCH NEXT 10 ROWS ONLY GO I consider it good enhancement in terms of T-SQL. I am sure many developers are waiting for this feature for long time. We will consider performance different in future posts.

• Visual Studio 2010 SP1 Beta supports IIS Express

  - by DigiMortal

  Visual Studio 2010 SP1 Beta and ASP.NET MVC 3 RC2 were both announced today. I made a little test on one of my web applications to see how Visual Studio 2010 works with IIS Express. In this posting I will show you how to make your ASP.NET MVC 3 application work with IIS Express. Installing new stuff You can install IIS Express using Web Platform Installer. It is not part of WebMatrix anymore and you can just install IIS Express without WebMatrix. NB! You have to install IIS Express using Web Platform installer because IIS Express is not installed by SP1. After installing Visual Studio 2010 SP1 Beta on my machine (it took a long-long-long time to install) I installed also ASP.NET MVC 3 RC2. If you have Async CTP installed on your machine you have to uninstall it to get ASP.NET MVC 3 RC2 installed and run without problems. Screenshot on right shows what kinf of horrors my old laptop had to survive to get all new stuff installer. Setting IIS Express as server for web application Now, when you right-click on some web project you should see new menu item in context menu – Use IIS Express…. If you click on it you are asked for confirmation and if you say Yes then your web application is reconfigured to use IIS Express. After configuration you will see dialog box like this. And you are done. You can run your application now. Running web application When you run your application it is run on IIS Express. You can see IIS Express icon on taskbar and when you click it you can open IIS Express settings. If you closed your application in browser you can open it again from IIS Express icon. Modifying IIS Express settings for web application You can modify IIS Express settings for your application. Just open your project properties and move to Web tab. IIS and IIS Express are using same settings. The difference is if you make check to Use IIS Express checkbox or not. Switching back to Visual Studio Development Server If you don’t want or you can’t use IIS Express for some reason you can easily switch back to Visual Studio Development Server. Just right-click on your web application project and select Use Visual Studio Development Server from context menu. Conclusion IIS Express is more independent than full version of IIS and it can be also installed and run on machines where are very strict rules (some corporate and academic environments by example). IIS Express was previously part of WebMatrix package but now it is separate product and Visual Studio 2010 has very nice support for it thanks to SP1. You can easily make your web applications use IIS Express and if you want to switch back to development server it is also very easy.

• Benchmarking Linux flash player and google chrome built in flash player

  - by Fischer

  I use xubuntu 14.04 64 bit, I installed flash player from software center and xubuntu-restricted-extras too Are there any benchmarks on Linux flash player and google chrome built in flash player? I just want to see their performance because in theory google's flash player should be more updated and have better performance than the one we use in Firefox. (that's what I read everywhere) I have chrome latest version installed and Firefox next, and I found that flash videos in Chrome are laggy and they take long time to load. While the same flash videos load much faster in Firefox and I tend to prefer watching flash videos in firefox, especially the long ones because it loads them so much faster. I can't believe these results on my PC, so is there any way to benchmark flash players performance on both browsers?
