• array and array_view from amp.h

  - by Daniel Moth

  This is a very long post, but it also covers what are probably the classes (well, array_view at least) that you will use the most with C++ AMP, so I hope you enjoy it! Overview The concurrency::array and concurrency::array_view template classes represent multi-dimensional data of type T, of N dimensions, specified at compile time (and you can later access the number of dimensions via the rank property). If N is not specified, it is assumed that it is 1 (i.e. single-dimensional case). They are rectangular (not jagged). The difference between them is that array is a container of data, whereas array_view is a wrapper of a container of data. So in that respect, array behaves like an STL container, whereas the closest thing an array_view behaves like is an STL iterator (albeit with random access and allowing you to view more than one element at a time!). The data in the array (whether provided at creation time or added later) resides on an accelerator (which is specified at creation time either explicitly by the developer, or set to the default accelerator at creation time by the runtime) and is laid out contiguously in memory. The data provided to the array_view is not stored by/in the array_view, because the array_view is simply a view over the real source (which can reside on the CPU or other accelerator). The underlying data is copied on demand to wherever the array_view is accessed. Elements which differ by one in the least significant dimension of the array_view are adjacent in memory. array objects must be captured by reference into the lambda you pass to the parallel_for_each call, whereas array_view objects must be captured by value (into the lambda you pass to the parallel_for_each call). Creating array and array_view objects and relevant properties You can create array_view objects from other array_view objects of the same rank and element type (shallow copy, also possible via assignment operator) so they point to the same underlying data, and you can also create array_view objects over array objects of the same rank and element type e.g.   array_view<int,3> a(b); // b can be another array or array_view of ints with rank=3 Note: Unlike the constructors above which can be called anywhere, the ones in the rest of this section can only be called from CPU code. You can create array objects from other array objects of the same rank and element type (copy and move constructors) and from other array_view objects, e.g.   array<float,2> a(b); // b can be another array or array_view of floats with rank=2 To create an array from scratch, you need to at least specify an extent object, e.g. array<int,3> a(myExtent);. Note that instead of an explicit extent object, there are convenience overloads when N<=3 so you can specify 1-, 2-, 3- integers (dependent on the array's rank) and thus have the extent created for you under the covers. At any point, you can access the array's extent thought the extent property. The exact same thing applies to array_view (extent as constructor parameters, incl. convenience overloads, and property). While passing only an extent object to create an array is enough (it means that the array will be written to later), it is not enough for the array_view case which must always wrap over some other container (on which it relies for storage space and actual content). So in addition to the extent object (that describes the shape you'd like to be viewing/accessing that data through), to create an array_view from another container (e.g. std::vector) you must pass in the container itself (which must expose .data() and a .size() methods, e.g. like std::array does), e.g.   array_view<int,2> aaa(myExtent, myContainerOfInts); Similarly, you can create an array_view from a raw pointer of data plus an extent object. Back to the array case, to optionally initialize the array with data, you can pass an iterator pointing to the start (and optionally one pointing to the end of the source container) e.g.   array<double,1> a(5, myVector.begin(), myVector.end()); We saw that arrays are bound to an accelerator at creation time, so in case you don’t want the C++ AMP runtime to assign the array to the default accelerator, all array constructors have overloads that let you pass an accelerator_view object, which you can later access via the accelerator_view property. Note that at the point of initializing an array with data, a synchronous copy of the data takes place to the accelerator, and then to copy any data back we'll see that an explicit copy call is required. This does not happen with the array_view where copying is on demand... refresh and synchronize on array_view Note that in the previous section on constructors, unlike the array case, there was no overload that accepted an accelerator_view for array_view. That is because the array_view is simply a wrapper, so the allocation of the data has already taken place before you created the array_view. When you capture an array_view variable in your call to parallel_for_each, the copy of data between the non-CPU accelerator and the CPU takes place on demand (i.e. it is implicit, versus the explicit copy that has to happen with the array). There are some subtleties to the on-demand-copying that we cover next. The assumption when using an array_view is that you will continue to access the data through the array_view, and not through the original underlying source, e.g. the pointer to the data that you passed to the array_view's constructor. So if you modify the data through the array_view on the GPU, the original pointer on the CPU will not "know" that, unless one of two things happen: you access the data through the array_view on the CPU side, i.e. using indexing that we cover below you explicitly call the array_view's synchronize method on the CPU (this also gets called in the array_view's destructor for you) Conversely, if you make a change to the underlying data through the original source (e.g. the pointer), the array_view will not "know" about those changes, unless you call its refresh method. Finally, note that if you create an array_view of const T, then the data is copied to the accelerator on demand, but it does not get copied back, e.g.   array_view<const double, 5> myArrView(…); // myArrView will not get copied back from GPU There is also a similar mechanism to achieve the reverse, i.e. not to copy the data of an array_view to the GPU. copy_to, data, and global copy/copy_async functions Both array and array_view expose two copy_to overloads that allow copying them to another array, or to another array_view, and these operations can also be achieved with assignment (via the = operator overloads). Also both array and array_view expose a data method, to get a raw pointer to the underlying data of the array or array_view, e.g. float* f = myArr.data();. Note that for array_view, this only works when the rank is equal to 1, due to the data only being contiguous in one dimension as covered in the overview section. Finally, there are a bunch of global concurrency::copy functions returning void (and corresponding concurrency::copy_async functions returning a future) that allow copying between arrays and array_views and iterators etc. Just browse intellisense or amp.h directly for the full set. Note that for array, all copying described throughout this post is deep copying, as per other STL container expectations. You can never have two arrays point to the same data. indexing into array and array_view plus projection Reading or writing data elements of an array is only legal when the code executes on the same accelerator as where the array was bound to. In the array_view case, you can read/write on any accelerator, not just the one where the original data resides, and the data gets copied for you on demand. In both cases, the way you read and write individual elements is via indexing as described next. To access (or set the value of) an element, you can index into it by passing it an index object via the subscript operator. Furthermore, if the rank is 3 or less, you can use the function ( ) operator to pass integer values instead of having to use an index object. e.g. array<float,2> arr(someExtent, someIterator); //or array_view<float,2> arr(someExtent, someContainer); index<2> idx(5,4); float f1 = arr[idx]; float f2 = arr(5,4); //f2 ==f1 //and the reverse for assigning, e.g. arr(idx[0], 7) = 6.9; Note that for both array and array_view, regardless of rank, you can also pass a single integer to the subscript operator which results in a projection of the data, and (for both array and array_view) you get back an array_view of rank N-1 (or if the rank was 1, you get back just the element at that location). Not Covered In this already very long post, I am not going to cover three very cool methods (and related overloads) that both array and array_view expose: view_as, section, reinterpret_as. We'll revisit those at some point in the future, probably on the team blog. Comments about this post by Daniel Moth welcome at the original blog.

• How do search engines handle hyphenated words?

  - by NinjaKC

  I am not sure my title fully explains what I mean. I thought this might be an interesting question. If I had a set of keywords, broken with a dash or 2, will search engines consider the dashed split keyword as maybe a full keyword? Say I have a site that sort of breaks words down, like the dictionary sites do. So a keyword for that page, might end up in the page, and / or the URL, as broken by dashes. Key-word = keyword Co-op-er-at-ive = cooperative Pho-to-gra-phy = Photography www.example.com/key-word/ www.example.com/co-op-er-at-ive/ www.example.com/pho-to-gra-phy/ I know search engines will consider a dash (at least Google) as a space, and understand it as multiple words. But in the English language, a dash can also break a word down (at least I think it can, can't it?), so will search engines also take this into consideration? I did a 'little' research, I Googled some words and placed random dashes, and it returned the words I searched for, but this could be considered a typo from the user on Google's search end, so really I am wondering if I can purposely put a dash in a keyword, and have the search engine spiders still catch that keyword as the real word without dashes? I've done a little Googling and looking here on Stackoverflow, but everything comes down to dashes for multiple words, not really the specific thing I'm trying to figure out. Hopefully that makes sense, I am not an expert in SEO, yet, but get the basics and have been playing, and this is just really a random question to satisfy my knowledge of playing :P

• Reset / Remove - Google Keywords

  - by Herr Kaleun

  Summary: My site is ranking for filthy keywords and i would like to remove them from google ranking/keywords. Background: My server was hacked using the timthumb exploit/security vulnerability, apparently i was the last person on earth to read the news about the exploit, several months after it appeared. Anyway, the "hacker" was so friendly to modify the index.php file in such a fashion, that it generated random sexual oriented keywords if the website is fetched as google-bot. So if you would fetch it as google bot/it gets indexed, you would get randomly generated keywords like: sex videos teenager teen sex adult sex preteen A LINK TO A RANDOM CONTENT OF MY WEBPAGE anime sex videos a rough list something similar to that, about 180-200 per page. I've discovered it far too late, so that google had me indexed for the words "sex" and certain adult oriented keywords, about roughly 2000. I've removed all the content, toke the site down, replaced the index.php with a static HTML and added a "ERROR 410" title to the website so that the content is no longer here and removed permanently. I've also applied for a manual review of my website, about 1.5 months ago but still, the keywords are there, and very strange, some of the keyword rankings actually "improve" over time. Here are some screenshots from webmasters tools: Question: How can i remove this filthy keywords and re-rank my website as a "normal" website on the fastest way? I want to "REMOVE" the keywords if possible. Please help me or point me into a direction. Thank you

• Newly installed Ubuntu 12.10 and weird graphics

  - by Benji Marshall

  My machine: 2 GB RAM Intel Pentium Dual core E2180 @ 2 GHz NVIDIA GeForce 6200 LE My friend had recommended Ubuntu to me and I thought I might as well get used to Linux in anticipation for my Raspberry Pi. He said that Wubi was the easiest way to install and I installed it using Wubi. On my first ever boot up of Ubuntu from the Windows Bootloader started normally, and I logged on in a normal fashion, and my desktop loaded normally. I then pressed the Windows key/Power key and everything went wrong. Random lines of yellow and blue appeared on my screen, and changed location when I moved my mouse. The lines stayed for a few seconds and then partially went to I could sort of use my computer. I tried moving my mouse and the entire desktop looked like it broke apart, fragments of it just scatter across my screen at random angles. I could move my mouse and the pointer would move but clicking did nothing. I had to turn off my machine by removing the plug. I would love to get off Windows, but at least the doesn't completely mess up the graphics, and is relatively usable. Please help me solve this....

• XNA Skinned Animated Mesh Rendering Exported from Maya

  - by Devin Garner

  I am working on translating an old RTS game engine I wrote from DirectX9 to XNA. My old models didn't have animation & are an old format, so I'm trying with an FBX file. I temporarily "borrowed" a model from League of Legends just to test if my rendering is working correctly. I imported the mesh/bones/skin/animation into Maya 2012 using an "unnamed" 3rd-party import tool. (obviously I'll have to get legit models later, but I just want to test if my programming is correct). Everything looks correct in maya and it renders the animations flawlessly. I exported everything into a single FBX file (with only a single animation). I then tried to load this model using the example at the following site: http://create.msdn.com/en-US/education/catalog/sample/skinned_model With my exported FBX, the animation looks correct for most of the frames, however at random times it screws up for a split second. Basically, the body/arms/head will look right, but the leg/foot will shoot out to a random point in space for a second & then go back to the normal position. The original FBX from the sample looks correct in my program. It seems odd that my model was imported into maya wrong, since it displays fine in Maya. So, I'm thinking either I'm exporting it wrong, or the sample code is bad & the model from the sample caters to the samples bad code. I'm new to 3D programming & maya, so chances are I'm doing something wrong in the export. I'm using mostly the defaults, but I've tried all 3 interpolation modes (quaternion, euler, resample). Thanks

• What is your most preferred method of site pagination?

  - by John Smith

  There seem to be quite a few implementations of this feature. Some sites like like Stackexchange have it laid out like this: [1][2][3][4][5] ... [954][Next] Other sites like game forums may have something like this: [1][2][3] ... [10] ... [50] ... [500] ... [954][Next] Some sites like webcomics (XKCD comes to mind) have it laid out like this: [Last][Prev][Random][Next][First] Reddit has a very simple pagination with only: [Prev][Next] Sites like Stackexchange and Google also allow you to change how many results you want per page. Personally, I have never used this feature. Is it even worth including or does it just further confuse the design with needless features? Personally, I have only ever seen the need for the webcomic style (without the random). If I need to go to a specific page (which is very, very rare) then I can just edit the address bar. Is it good design to make something more complex for rare occasions where it might make save the user some time? Is having to edit the address bar to navigate the site effectively in some circumstances bad design?

• Rendering a big game universe - bitmaps or vector graphics?

  - by user1641923

  I am new to an Android development, though I have much experience with Java, C++, PHP programming and a bit experience with vector graphics too (basic 3d Studio Max, Flash, etc). I am starting to work on an Android game. It is going to be a 2D space shooter/RPG, and I am not going to use any game engines and any 3D party libs. I really want to create a very large game universe, or even pseudo-infinite (without visible borders, as if it were a 2D projection of a sphere). It should include 10-12 clusters of 7-8 planets/other space objects and random amount of single asteroids/comets, which player can interact with and also not interactive background. I am looking for a least complicated aproach to create such a universe. My current ideas are: Simply create bitmaps with space scenery background so that they can be tiled seamlessly repeated and construct my 2D universe of this tiles, then place interactive objects (planets, other spaceships) on it. Using vector graphics. I would have a solid color background, some random background objects and gradients here and there. My problems here: Lack of knowledge of how well vector graphics is integrated in Android. Performance? Memory usage? Does Android manage big bitmaps well? Do all of the bitmaps have to be in memory during all game process? I am interested in technical details regarding each of the ideas and a suggestion, which I should go with.

• Windows Phone 7 : Dragging and flicking UI controls

  - by TechTwaddle

  Who would want to flick and drag UI controls!? There might not be many use cases but I think some concepts here are worthy of a post. So we will create a simple silverlight application for windows phone 7, containing a canvas element on which we’ll place a button control and an image and then, as the title says, drag and flick the controls. Here’s Mainpage.xaml, <Grid x:Name="LayoutRoot" Background="Transparent">   <Grid.RowDefinitions>     <RowDefinition Height="Auto"/>     <RowDefinition Height="*"/>   </Grid.RowDefinitions>     <!--TitlePanel contains the name of the application and page title-->   <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">     <TextBlock x:Name="ApplicationTitle" Text="KINETICS" Style="{StaticResource PhoneTextNormalStyle}"/>     <TextBlock x:Name="PageTitle" Text="drag and flick" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>   </StackPanel>     <!--ContentPanel - place additional content here-->   <Grid x:Name="ContentPanel" Grid.Row="1" >     <Canvas x:Name="MainCanvas" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">       <Canvas.Background>         <LinearGradientBrush StartPoint="0 0" EndPoint="0 1">           <GradientStop Offset="0" Color="Black"/>           <GradientStop Offset="1.5" Color="BlanchedAlmond"/>         </LinearGradientBrush>       </Canvas.Background>     </Canvas>   </Grid> </Grid> the second row in the main grid contains a canvas element, MainCanvas, with its horizontal and vertical alignment set to stretch so that it occupies the entire grid. The canvas background is a linear gradient brush starting with Black and ending with BlanchedAlmond. We’ll add the button and image control to this canvas at run time. Moving to Mainpage.xaml.cs the Mainpage class contains the following members, public partial class MainPage : PhoneApplicationPage {     Button FlickButton;     Image FlickImage;       FrameworkElement ElemToMove = null;     double ElemVelX, ElemVelY;       const double SPEED_FACTOR = 60;       DispatcherTimer timer; FlickButton and FlickImage are the controls that we’ll add to the canvas. ElemToMove, ElemVelX and ElemVelY will be used by the timer callback to move the ui control. SPEED_FACTOR is used to scale the velocities of ui controls. Here’s the Mainpage constructor, // Constructor public MainPage() {     InitializeComponent();       AddButtonToCanvas();       AddImageToCanvas();       timer = new DispatcherTimer();     timer.Interval = TimeSpan.FromMilliseconds(35);     timer.Tick += new EventHandler(OnTimerTick); } We’ll look at those AddButton and AddImage functions in a moment. The constructor initializes a timer which fires every 35 milliseconds, this timer will be started after the flick gesture completes with some inertia. Back to AddButton and AddImage functions, void AddButtonToCanvas() {     LinearGradientBrush brush;     GradientStop stop1, stop2;       Random rand = new Random(DateTime.Now.Millisecond);       FlickButton = new Button();     FlickButton.Content = "";     FlickButton.Width = 100;     FlickButton.Height = 100;       brush = new LinearGradientBrush();     brush.StartPoint = new Point(0, 0);     brush.EndPoint = new Point(0, 1);       stop1 = new GradientStop();     stop1.Offset = 0;     stop1.Color = Colors.White;       stop2 = new GradientStop();     stop2.Offset = 1;     stop2.Color = (Application.Current.Resources["PhoneAccentBrush"] as SolidColorBrush).Color;       brush.GradientStops.Add(stop1);     brush.GradientStops.Add(stop2);       FlickButton.Background = brush;       Canvas.SetTop(FlickButton, rand.Next(0, 400));     Canvas.SetLeft(FlickButton, rand.Next(0, 200));       MainCanvas.Children.Add(FlickButton);       //subscribe to events     FlickButton.ManipulationDelta += new EventHandler<ManipulationDeltaEventArgs>(OnManipulationDelta);     FlickButton.ManipulationCompleted += new EventHandler<ManipulationCompletedEventArgs>(OnManipulationCompleted); } this function is basically glorifying a simple task. After creating the button and setting its height and width, its background is set to a linear gradient brush. The direction of the gradient is from top towards bottom and notice that the second stop color is the PhoneAccentColor, which changes along with the theme of the device. The line,     stop2.Color = (Application.Current.Resources["PhoneAccentBrush"] as SolidColorBrush).Color; does the magic of extracting the PhoneAccentBrush from application’s resources, getting its color and assigning it to the gradient stop. AddImage function is straight forward in comparison, void AddImageToCanvas() {     Random rand = new Random(DateTime.Now.Millisecond);       FlickImage = new Image();     FlickImage.Source = new BitmapImage(new Uri("/images/Marble.png", UriKind.Relative));       Canvas.SetTop(FlickImage, rand.Next(0, 400));     Canvas.SetLeft(FlickImage, rand.Next(0, 200));       MainCanvas.Children.Add(FlickImage);       //subscribe to events     FlickImage.ManipulationDelta += new EventHandler<ManipulationDeltaEventArgs>(OnManipulationDelta);     FlickImage.ManipulationCompleted += new EventHandler<ManipulationCompletedEventArgs>(OnManipulationCompleted); } The ManipulationDelta and ManipulationCompleted handlers are same for both the button and the image. OnManipulationDelta() should look familiar, a similar implementation was used in the previous post, void OnManipulationDelta(object sender, ManipulationDeltaEventArgs args) {     FrameworkElement Elem = sender as FrameworkElement;       double Left = Canvas.GetLeft(Elem);     double Top = Canvas.GetTop(Elem);       Left += args.DeltaManipulation.Translation.X;     Top += args.DeltaManipulation.Translation.Y;       //check for bounds     if (Left < 0)     {         Left = 0;     }     else if (Left > (MainCanvas.ActualWidth - Elem.ActualWidth))     {         Left = MainCanvas.ActualWidth - Elem.ActualWidth;     }       if (Top < 0)     {         Top = 0;     }     else if (Top > (MainCanvas.ActualHeight - Elem.ActualHeight))     {         Top = MainCanvas.ActualHeight - Elem.ActualHeight;     }       Canvas.SetLeft(Elem, Left);     Canvas.SetTop(Elem, Top); } all it does is calculate the control’s position, check for bounds and then set the top and left of the control. OnManipulationCompleted() is more interesting because here we need to check if the gesture completed with any inertia and if it did, start the timer and continue to move the ui control until it comes to a halt slowly, void OnManipulationCompleted(object sender, ManipulationCompletedEventArgs args) {     FrameworkElement Elem = sender as FrameworkElement;       if (args.IsInertial)     {         ElemToMove = Elem;           Debug.WriteLine("Linear VelX:{0:0.00}  VelY:{1:0.00}", args.FinalVelocities.LinearVelocity.X,             args.FinalVelocities.LinearVelocity.Y);           ElemVelX = args.FinalVelocities.LinearVelocity.X / SPEED_FACTOR;         ElemVelY = args.FinalVelocities.LinearVelocity.Y / SPEED_FACTOR;           timer.Start();     } } ManipulationCompletedEventArgs contains a member, IsInertial, which is set to true if the manipulation was completed with some inertia. args.FinalVelocities.LinearVelocity.X and .Y will contain the velocities along the X and Y axis. We need to scale down these values so they can be used to increment the ui control’s position sensibly. A reference to the ui control is stored in ElemToMove and the velocities are stored as well, these will be used in the timer callback to access the ui control. And finally, we start the timer. The timer callback function is as follows, void OnTimerTick(object sender, EventArgs e) {     if (null != ElemToMove)     {         double Left, Top;         Left = Canvas.GetLeft(ElemToMove);         Top = Canvas.GetTop(ElemToMove);           Left += ElemVelX;         Top += ElemVelY;           //check for bounds         if (Left < 0)         {             Left = 0;             ElemVelX *= -1;         }         else if (Left > (MainCanvas.ActualWidth - ElemToMove.ActualWidth))         {             Left = MainCanvas.ActualWidth - ElemToMove.ActualWidth;             ElemVelX *= -1;         }           if (Top < 0)         {             Top = 0;             ElemVelY *= -1;         }         else if (Top > (MainCanvas.ActualHeight - ElemToMove.ActualHeight))         {             Top = MainCanvas.ActualHeight - ElemToMove.ActualHeight;             ElemVelY *= -1;         }           Canvas.SetLeft(ElemToMove, Left);         Canvas.SetTop(ElemToMove, Top);           //reduce x,y velocities gradually         ElemVelX *= 0.9;         ElemVelY *= 0.9;           //when velocities become too low, break         if (Math.Abs(ElemVelX) < 1.0 && Math.Abs(ElemVelY) < 1.0)         {             timer.Stop();             ElemToMove = null;         }     } } if ElemToMove is not null, we get the top and left values of the control and increment the values with their X and Y velocities. Check for bounds, and if the control goes out of bounds we reverse its velocity. Towards the end, the velocities are reduced by 10% every time the timer callback is called, and if the velocities reach too low values the timer is stopped and ElemToMove is made null. Here’s a short video of the program, the video is a little dodgy because my display driver refuses to run the animations smoothly. The flicks aren’t always recognised but the program should run well on an actual device (or a pc with better configuration), You can download the source code from here: ButtonDragAndFlick.zip

• The remote server returned an error: 227 Entering Passive Mode

  - by hmloo

  Today while uploading file to FTP sever, the codes throw an error - "The remote server returned an error: 227 Entering Passive Mode", after research, I got some knowledge in FTP working principle. FTP may run in active or passive mode, which determines how the data connection is established. Active mode: command connection: client >1024  -> server 21 data connection:    client >1024  <-  server 20 passive mode: command connection: client > 1024 -> server 21 data connection:    client > 1024 <- server > 1024 In active mode, the client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the client will use PORT command to tell the server:"hi, I opened port XXXX, please connect to me." and then server will use port 20 to initiate the data connection to that client port number. In passive mode, the client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the sever will tell the client:"hi, I opened port XXXX , please connect to me." and then client will initiate the data connection to that sever port number. In a nutshell, active mode is used to have the server connect to the client, and passive mode is used to have the client connect to the server. So if your FTP server is configured to work in active mode only or the firewalls between your client and the server are blocking the data port range, then you will get error message, to fix this issue, just set System.Net.FtpWebRequest property UsePassive = false. Hope this helps! Thanks for reading!

• How to implement smart card authentication with a .NET Fat client?

  - by John Nevermore

  I know very little about smart card authentication in general so please point out or correct me if anything below doesn't make sense. Lets say i have: A Certificate Authority "X"-s smart card (non-exportable private key) Drivers for that smart card written in C A smart card reader CA-s authentication OCSP web service A requirement to implement user authentication in a .NET fat client application via a smart card, that was given out by the CA "X". I tried searching info on the web but no prevail. What would the steps be ? My first thought was: Set up a web service, that would allow saving of (for example) scores of a ping pong game for each user. Each time someone tries to submit a score via the client application, he can only do so by inserting the smart card into the reader. Then the public key is read from the smart card by native c calls through .NET and sent to my custom web service, which in return uses the CA-s authentication OCSP web service to prove the validity of the public key/public certificate (?). If the public key is okay and valid, encrypt a random sequence of bytes with the public key and send it to the client application. If the client application sends back the correctly decrypted random sequence of bytes along with the score of the ping pong game, then the score is saved in the database for the given user. My question is, is this the correct way to do it ? What else should i know about smart card authentication ?

• Building a template engine - starting point

  - by Anirudh

  We're building a Django-based project with a template component. This component will be separate from the project as such and can be Django/Python, Node, Java or whatever works. The template has to be rendered into HTML. The templates will contain references to objects with properties that are defined in the DB, say, a Bus. For eg, it could be something like [object type="vehicle" weight="heavy"] and it would have to pull a random object from the DB fulfilling the criteria : type="vehicle" weight="heavy" (bus/truck/jet) and then substitute that tag with an image, say, of a Bus. Also it would have to be able to handle some processing. Eg: What is [X type="integer" lte="10"] + [Y type="integer" lte="10"] [option X+Y correct_ans="true"] [option X-Y correct_ans="false"] [option X+y+1 correct_ans="false"] The engine would be expected to fill in a random integer value <= 10 for X and Y and show radioboxes for each of the options. Would also have to store the fact that the first option is the correct answer. Does it to make sense to write something from the scratch? Or is it better to use an existing templating system (like Django's own templating system) as a starting point? Any suggestions on how I can approach this?

• External monitor problems with Asus UX32VD in 12.04

  - by rsilva

  I've posted this video where I show one of the problems I'm facing with my UX32VD in regard of external monitors. As you can see as soon as I plugged the external monitor the laptop screen goes black and the external monitor displays a single color (color changes between red, green and blue). However this does not always happen. For instance if I reboot the laptop with the external monitor already plugged in I get to use it but not the laptop screen. In the Displays settings the laptop screen it's not even listed. Other times it just works. The to screens, without any problems. I tried with other to different external monitor and all this apparently random issues repeat, I even tried using HDMI cable instead. Same random behavior. This question seams to cover one of this issues however the answer did not helped me. I was forced to use the 3.5.2 kernel in order to use the Intel graphics card else the Gallium something was used. Also I've Bumblebee installed.

• Limiting calls to WCF services from BizTalk

  - by IntegrationOverload

  ** WORK IN PROGRESS ** This is just a placeholder for the full article that is in progress. The problem My BTS solution was receiving thousands of messages at once. After processing by BTS I needed to send them on via one of several WCF services depending on the message content. The problem is that due to the asynchronous nature of BizTalk the WCF services were getting hammered and could not cope with the load. Note: It is possible to limit the SOAP calls in the BtsNtSvc.exe.Config file but that does not have the desired results for Net-TCP WCF services. The solution So I created a new MessageType for the messages in question and posted them to the BTS messaeg box. This schema included the URL they were being sent to as a promoted property. I then subscribed to the message type from a new orchestraton (that does just the WCF send) using the URL as a correlation ID. This created a singleton orchestraton that was instantiated when the first message hit the message box. It then waits for further messages with the same correlation ID and type and processs them one at a time using a loop shape with a timer (A pretty standard pattern for processing related messages) Image to go here This limits the number of calls to the individual WCF services to 1. Which is a good start but the service can handle more than that and I didn't want to create a bottleneck. So I then constructed the Correlation ID using the URL concatinated with a random number between 1 and 10. This makes 10 possible correlation IDs per URL and so 10 instances of the singleton Orchestration per WCF service. Just what I needed and the upper random number is a configuration value in SSO so I can change the maximum connections without touching the code.

• Calculating the correct particle angle in an outwards explosion

  - by Sun

  I'm creating a simple particle explosion but am stuck in finding the correct angle to rotate my particle. The effect I'm going for is similar to this: Where each particle is going outwards from the point of origin and at the correct angle. This is what I currently have: As you can see, each particle is facing the same angle, but I'm having a little difficulty figuring out the correct angle. I have the vector for the point of emission and the new vector for each particle, how can I use this to calculate the angle? Some code for reference: private Particle CreateParticle() { ... Vector2 velocity = new Vector2(2.0f * (float)(random.NextDouble() * 2 - 1), 2.0f * (float)(random.NextDouble() * 2 - 1)); direction = velocity - ParticleLocation; float angle = (float)Math.Atan2(direction.Y, direction.X); ... return new Particle(texture, position, velocity, angle, angularVelocity, color, size, ttl, EmitterLocation); } I am then using the angle created as so in my particles Draw method: spriteBatch.Draw(Texture, Position, null, Color, Angle, origin, Size, SpriteEffects.None, 0f);

• Yelp, Google's API for restaurants help

  - by chris

  Ok I have looked into this, and I'm not sure if anyone else has experience with it. I'm having termendous difficulties with Yelp and Google's API. To help explain what I am trying to do here is the concept of the website. We would have to pull restaurants based on user distance, and then randomize them based on quality of restaurant based on feedback from review websites (Yelp, Google, urbanspoon, zagat, opentable, kudzu, yahoo - doesn't have to be from all), and feedback from our users (on results page for the random restaurant users can select good recommendation/bad recommendation). There’s a lot we could calculate for our formula. Things that will dictate your results will be based on if you’re at home or work. If you’re at home you will have more time to drive out to the city to grab some dinner or lunch. If you’re at work we would have to recommend restaurants nearby as lunch is typically 30 minutes to a hour. A 30 minute lunch would require take out most likely or quick service. A hour lunch break you could dine in at a local fine dining restaurant. So in a nutshell, user comes to website. Select if they're at home or work, click submit and we will have a random restaurant selected for them to go. If they don't like it they can click retry and a new restaurant can show. The issue I am having is using the API to gather all the restaurants in the US. I know it can be done because there are similiar websites/apps that pull restaurants that are closest to you such as Ness, Alfred, and I believe there's two more but I can't remember the names. Anyone know if this can be accomplish?

• Android - big game universe

  - by user1641923

  I am new to an Android development, though I have much experience with Java, C++, PHP programming and a bit experience with vector graphics too (basic 3d Studio Max, Flash, etc). I am starting to work on an Android game. It is going to be a 2D space shooter/RPG, and I am not going to use any game engines and any 3D party libs. I really want to create a very large game universe, or even pseudo-infinite (without visible borders, as if it were a 2D projection of a sphere). It should include 10-12 clusters of 7-8 planets/other space objects and random amount of single asteroids/comets, which player can interact with and also not interactive background. I am looking for a least complicated aproach to create such a universe. My current ideas are: Simply create bitmaps with space scenery background so that they can be tiled seamlessly repeated and construct my 2D universe of this tiles, then place interactive objects (planets, other spaceships) on it. Using vector graphics. I would have a solid color background, some random background objects and gradients here and there. My problems here: Lack of knowledge of how well vector graphics is integrated in Android. Performance? Memory usage? Does Android manage big bitmaps well? Do all of the bitmaps have to be in memory during all game process? I am interested in technical details regarding each of the ideas and a suggestion, which I should go with.

• Creating deterministic key pairs in javascript for use in encrypting/decrypting/signing messages

  - by SlickTheNick

  So I have been searching everywhere and havn't been able to find anything with the sufficient information I need.. so Im a bit stumped on this one at the moment What I am trying to do is create a public/private key pair (like PGP) upon a users account creation, based on their passphrase and a random seed. The public key would be saved on the server, and ideally the private key would never be seen by the server whatsoever. The user could then sign in, and send a message to another user. Before the message is sent, the senders key pair would be re-generated on the fly based on their credentials (and maybe a password prompt) and used to encrypt the message. The receiver would then use their own re-generated private key to decrypt said message. The server itself should never see any plaintext passwords, private keys or readable messages. Bit unsure how on how I could go about implementing this. Iv been looking into PGP, specifically openPGP.js. The main trouble I am having is being able to regenerate the key-pair based off a specific seed. PGP seems to have a random output even if the inputs are the same. Storing the private key in a cookie or in HTML5 storage or something also isnt really an option, too unreliable. Can anyone point me in the right direction?

• Ubuntu 11.04 64bits Keeps Randomly Freezing

  - by user971602

  This has been a real headache for me since the number of freezes has increase from twice a week to about 1 or twice a day. The system just halts and nothing can be done but hitting the restart button. At the beginning I thought it was related to Flash since I was getting random freezes when playing full screen flash videos online. I also thought it could be the wireless pci card. But the system has freezed using browsing around GNOME. The truth is, the freezes are really random and strange. I checked this thread Ubuntu keeps randomly freezing and try to ssh my computer using another one, but I could not ssh since it was really totally frozen. NumLock or CapsLock wasn't responding or blinking. Since I could not ssh I, also ignored this article https://wiki.ubuntu.com/X/Troubleshooting/Freeze According to my wife, the system has also halted under Win7 Pro 64bit but with less frequency. Here is my system configuration Intel Core i7 2600k ASRock Z68 Extreme3 gen3 Motherboard Crucial M4 128GB CT128M4SSD2 SSD WD Caviar Green WD10EADS 1TB SATA II G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR2 OCZ ModXStream 600W Power Supply Rosewill RNX-N300X PCI Wireless Adapter No external Graphics Card I remove the Wireless card and used Ethernet to see if the problem was the that, but I got a freeze after doing that. I also ran memtest86 and everything was ok. The only other thing I might suspect of is the SSD. I will try to clone the SSD to a HDD to see if that solve the problem. At this point I am stuck with the freezes. Do anyone have a clue of why this is happening and how can i solve this?

• Facebook contest policy no-no?

  - by Fred

  I would like to post a link on a Facebook page where it will exit Facebook entirely and go to a client's website, where people will be on a page (client's) where they can enter their e-mail address to be entered in a temporary database file with rules and disclosures etc., for a draw once the number of entries reaches 100 for instance. Once the number of entries reaches 100, a random winner is picked and notified via E-mail. The functionality is as follows: A link is place on a Facebook page leading to an external page The page is a form to merely enter their email address for a contest The email is placed in a temporary file An automatic E-mail is sent to the address used for confirmation using SHAH-256 hash The person receives the Email saying something to the affect "Please confirm your Email address etc. - If you did not authorize this, simply ignore this message and no further action will be taken". If the person clicks on the confirmation link, the Email is then stored in the database and the person is again notified saying "Thank you for signing up etc." Once others do the same process and the database reaches a certain number, the form is no longer accessible and automatically picks a random Email. Once picked, an Email is automatically sent to the winner stating the instructions, and notifying me also. Once that person clicks yet another confirmation link, the database is then automatically deleted. I have built this myself and have no intentions of breaking any rules, nor jeopardize the work/time/energy I have put into this project. Is this allowed?

• Dropping multiple objects using an array in Actionscript?

  - by Eratosthenes

  I'm trying to get these fireBalls to drop more often, I'm not sure if I'm using Math.random correctly. Also, for some reason I'm getting a null reference because I think the fireBalls array waits for one to leave the stage before dropping another one? This is the relevant code: var sun:Sun=new Sun var fireBalls:Array=new Array() var left:Boolean; function onEnterFrame(event:Event){ if (left) { sun.x = sun.x - 15; }else{ sun.x = sun.x + 15; } if (fireBalls.length>0&&fireBalls[0].y>stage.stageHeight){ // Fireballs exit stage removeChild(fireBalls[0]); fireBalls.shift(); } for (var j:int=0; j<fireBalls.length; j++){ fireBalls[j].y=fireBalls[j].y+15; if (fireBalls[j].y>stage.stageHeight-fireBall.width/2){ } } if (Math.random()<.2){ // Fireballs shooting from Sun var fireBall:FireBall=new FireBall; fireBall.x=sun.x; addChild(fireBall); fireBalls.push(fireBall); } }

• Map rendering Libgdx Java

  - by user3165683

  Ok, so I am trying to create a 2D non-movable random tiled map. This is what I have so far: private void generateTile(){ System.out.print("tiletry1"); while(loadedTiles != 8100){ System.out.print("tiletry"); Texture currentTile = null; int tileX = 0; int tileY = 0; if (tileX == 120); tileY = 16; tileX = 0; game.batch.begin(); switch(MathUtils.random(2)){ case 0: //game.batch.draw(tile1, tileX, tileY); System.out.print("tile1"); currentTile = tile1; break; case 1: //game.batch.draw(tile2, tileX, tileY); System.out.print("tile2"); currentTile = tile2; break; case 2: //game.batch.draw(tile3, tileX, tileY); System.out.print("tile3"); currentTile = tile3; break; } tileX+=16; loadedTiles ++; game.batch.draw(currentTile, tileX, tileY); game.batch.end(); } } However, I can't see any of the tiles and the screen just looks green. This method is above my render method which I have: camera.update(); batch.setProjectionMatrix(camera.combined); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); game.batch.begin(); //other render stuff Why am I not able to see the tiles?

• How do I get the PreviewDialog of Apache FOP to actually display my document?

  - by JRSofty

  Search as I may I have not found a solution to my problem here and I'm hoping the combined minds of StackOverflow will push me in the right direction. My problem is as follows, I'm developing a print and print preview portion of a messaging system's user agent. I was given specific XSLT templates that after transforming XML will produce a Formatting Objects document. With Apache FOP I've been able to render the FO document into PDF which is all fine and good, but I would also like to display it in a print preview dialog. Apache FOP contains such a class called PreviewDialog which requires in its constructor a FOUserAgent, which I can generate, and an object implementing the Renderable Interface. The Renderable Interface has one implementing class in the FOP package which is called InputHandler which takes in its constructor a standard io File object. Now here is where the trouble begins. I'm currently storing the FO document as a temp file and pass this as a File object to an InputHandler instance which is then passed to the PreviewDialog. I see the dialog appear on my screen and along the bottom in a status bar it says that it is generating the document, and that is all it does. Here is the code I'm trying to use. It isn't production code so it's not pretty: import java.io.BufferedOutputStream; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import java.util.Random; import javax.xml.transform.Result; import javax.xml.transform.Source; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerConfigurationException; import javax.xml.transform.TransformerException; import javax.xml.transform.TransformerFactory; import javax.xml.transform.sax.SAXResult; import javax.xml.transform.stream.StreamResult; import javax.xml.transform.stream.StreamSource; import org.apache.fop.apps.FOPException; import org.apache.fop.apps.FOUserAgent; import org.apache.fop.apps.Fop; import org.apache.fop.apps.FopFactory; import org.apache.fop.cli.InputHandler; import org.apache.fop.render.awt.viewer.PreviewDialog; public class PrintPreview { public void showPreview(final File xslt, final File xmlSource) { boolean err = false; OutputStream out = null; Transformer transformer = null; final String tempFileName = this.getTempDir() + this.generateTempFileName(); final String tempFoFile = tempFileName + ".fo"; final String tempPdfFile = tempFileName + ".pdf"; System.out.println(tempFileName); final TransformerFactory transformFactory = TransformerFactory .newInstance(); final FopFactory fopFactory = FopFactory.newInstance(); try { transformer = transformFactory .newTransformer(new StreamSource(xslt)); final Source src = new StreamSource(xmlSource); out = new FileOutputStream(tempFoFile); final Result res = new StreamResult(out); transformer.transform(src, res); System.out.println("XSLT Transform Completed"); } catch (final TransformerConfigurationException e) { err = true; e.printStackTrace(); } catch (final FileNotFoundException e) { err = true; e.printStackTrace(); } catch (final TransformerException e) { err = true; e.printStackTrace(); } finally { if (out != null) { try { out.close(); } catch (final IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } System.out.println("Initializing Preview"); transformer = null; out = null; final File fo = new File(tempFoFile); final File pdf = new File(tempPdfFile); if (!err) { final FOUserAgent ua = fopFactory.newFOUserAgent(); try { transformer = transformFactory.newTransformer(); out = new FileOutputStream(pdf); out = new BufferedOutputStream(out); final Fop fop = fopFactory.newFop( MimeConstants.MIME_PDF, ua, out); final Source foSrc = new StreamSource(fo); final Result foRes = new SAXResult(fop.getDefaultHandler()); transformer.transform(foSrc, foRes); System.out.println("Transformation Complete"); } catch (final FOPException e) { err = true; e.printStackTrace(); } catch (final FileNotFoundException e) { err = true; e.printStackTrace(); } catch (final TransformerException e) { err = true; e.printStackTrace(); } finally { if (out != null) { try { out.close(); } catch (final IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } if (!err) { System.out.println("Attempting to Preview"); final InputHandler inputHandler = new InputHandler(fo); PreviewDialog.createPreviewDialog(ua, inputHandler, true); } } // perform the clean up // f.delete(); } private String getTempDir() { final String p = "java.io.tmpdir"; return System.getProperty(p); } private String generateTempFileName() { final String charset = "abcdefghijklmnopqrstuvwxyz1234567890abcdefghijklmnopqrstuvwxyz1234567890"; final StringBuffer sb = new StringBuffer(); Random r = new Random(); int seed = r.nextInt(); r = new Random(seed); for (int i = 0; i < 8; i++) { final int n = r.nextInt(71); seed = r.nextInt(); sb.append(charset.charAt(n)); r = new Random(seed); } return sb.toString(); } } Any help on this would be appreciated.
