  • Detecting if an object is following a path

    - by justin.m.chase
    I am attempting to take GPS data and track it on a map and see if it follows a given path. I have the path as a set of points and the GPS data streams in as a similar set of points. I am attempting to track the progression of the current position across the path and I am wondering if there are any well known algorithms for this. I have come up with my own that works ok but it is a complex enough problem that I would like to minimize the amount of re-inventing of the wheel that I do. What approach or algorithm would you recommend taking for this problem?

  • How to "translate" interdependent object states in code?

    - by Earl Grey
    I have the following problem. My UI interace contains several buttons, labels, and other visual information. I am able to describe every possible workflow scenario that should be be allowed on that UI. That means I can describe it like this - when button A is pressed, the following should follow - In the case of that A button, there are three independent factors that influence the possible result when pushing the A button. The state of the session (blank, single, multi, multi special), the actual work that is being done by the system at the moment of pressing the A button (nothing was happening, work was being done, work was paused) and a separate UI element that has two states (on , off)..This gives me a 3 dimensional cube with 24 possible outcomes. I could write code for this using if cycles, switch cycles etc....but the problem is, I have another 7 buttons on that ui, I can enter this UI from different states..some buttons change the state, some change parameters... To sum up, the combinations are mindbogling and I am not able come up with a methodology that scales and is systematically reliable. I am able to describe EVERY workflow with words, I am sure my description is complete and without logical errors. But I am not able to translate that into code. I was trying to draw flowcharts but it soon became visually too complicated due to too many if "emafors". Can you advice how to proceeed?

  • How to remove the graphical user interface?

    - by Praveen Kumar
    Ok my question is that, I want to run a heavy application, on a Virtual Machine (VirtualBox) with just 2 GB RAM (Windows 7 32Bit Host has 4 GB, 3.5 GB effective). Initially I thought of installing Ubuntu Server 12.04.1, which doesn't come with a GUI, so I thought it would be efficient in performance, but I have only Ubuntu 12.04 Desktop. My question is, is it possible to remove the GUI parts in Ubuntu 12.04 Desktop (Not Server), keeping only the core OS, after installation in a virtual machine? Or, is there anyway to improve the performance of the OS? If you need more information, I am ready to provide. I don't want the GUI or anything, even a small terminal window is fine for me, I can access files through FTP.

  • Creating user UI using Flixel

    - by Jamie Read
    I am new to game development but familiar with programming languages. I have started using Flixel and have a working Breakout game with score and lives. What I am trying to do is add a Start Screen before actually loading the game. I have a create function that adds all the game elements to the stage: override public function create():void // all game elements { How can I add this pre-load Start Screen? I'm not sure if I have to add in the code to this create function or somewhere else and what code to actually add. Eventually I would also like to add saving, loading, options and upgrades too. So any advice with that would be great. Here is my main game.as: package { import org.flixel.*; public class Game extends FlxGame { private const resolution:FlxPoint = new FlxPoint(640, 480); private const zoom:uint = 2; private const fps:uint = 60; public function Game() { super(resolution.x / zoom, resolution.y / zoom, PlayState, zoom); FlxG.flashFramerate = fps; } } } Thanks.

  • Securely automount encrypted drive at user login

    - by Tom Brossman
    An encrypted /home directory gets mounted automatically for me when I log in. I have a second internal hard drive that I've formatted and encrypted with Disk Utility. I want it to be automatically mounted when I login, just like my encrypted /home directory is. How do I do this? There are several very similar questions here, but the answers don't apply to my situation. It might be best to close/merge my question here and edit the second one below, but I think it may have been abandoned (and therefore never to be marked as accepted). This solution isn't a secure method, it circumvents the encryption. This one requires editing fstab, which necessitates entering an additional password at boot. It's not automatic like mounting /home. This question is very similar, but does not apply to an encrypted drive. The solution won't work for my needs. Here is one but it's for NTFS drives, mine is ext4. I can re-format and re-encrypt the second drive if a solution requires this. I've got all the data backed up elsewhere.

  • Great User Group if based near Gloucester + Links from Entity Framework 4.0 session

    - by Eric Nelson
    I had a really fun evening doing “my final” EF 4.0 session last night (26th May 2010) at GL.NET based out of Gloucester (although secretly I made it into a IronRuby and Windows Azure session). They are a great crowd and Jimmy makes for a fantastic host + it is a very nice venue (Symantec offices in Gloucester, lots of parking, good room etc) + free pizza + free SWAG + trip to pub afterwards (the topics were very varied!). What more could you ask for? The next session is June 16th and will be on multi-tenanted ASP.NET MVC and comes highly recommended. Links from my session: Entity Framework 4 Resources http://bit.ly/ef4resources Entity Framework Team Blog http://blogs.msdn.com/adonet Entity Framework Design Blog http://blogs.msdn.com/efdesign/ The must have LINQPad http://www.linqpad.net Entity Framework Profile http://efprof.com/  IronRuby info on my blog http://geekswithblogs.net/iupdateable/category/10076.aspx

  • How to force user to use subdomain?

    - by David Stockinger
    I am hosting a webshop with OpenCart and its current URL is e.g. http://mydomain.com/shop/ I have created two subdomains ( http://pg.mydomain.com/ and http://shop.mydomain.com/ ) and both subdomains are already working as they should. However, can I restrict direct access to mydomain.com/shop/ while leaving all the files (index.php, etc.) there? Since both subdomains are pointing to http://mydomain.com/shop/, I thought this would restrict all access. So in the end, I would like my two shops to be accessable through http://pg.mydomain.com/ and http://shop.mydomain.com/, but not http://mydomain.com/shop/ while leaving all the files in http://mydomain.com/shop/.

  • Communication between Page and User Controls

    - by Narmatha Balasundaram
    I have a main page that has multiple user controls on it. All the user controls have static text and some data to be retrieved from the DB. The aysnchronous DB call is clubbed at the page level and one call is made to avoid multiple calls (in the different user controls) to get the same data. I want the page and user controls to load initially with the static text and later refresh the contents obtained from the server. To sum it all up, Page Loads = Asyn calls fired on page load = Data received back from the server (XML/text/whatever) = User controls to load with this data using AJAX. What methods do I have to let the user controls know that I have the data from the server and they need to update with this data?

  • install software in linux as a non root user

    - by Aki
    Hi, What is the best way to install software in a linux machine if you dont have root permissions. I know that we can use few variables like PKG_CONFIG_PATH and switches like --prefix with configure to get a software installed in a local directory, but sometimes when there are recursive dependencies it is becoming tough for me to install all the packages manually. Is there a better automated way? Update: What i meant by recursive dependencies is: to install package A, i should install package B, which in turn requires package C to be installed

  • Blender: How to "meshify" an object I made from Bezier curves

    - by capcom
    I made a star shape using Bezier curves, and extruded it (see pic below): What I want to do is give it a rounder look - not just around the edges by using beveling. I want it to kind of look like this (well, that shape anyway): How would I go about doing this? Please keep in mind that I am extremely new to Blender. I thought that I could somehow turn this star into those default shapes that have tonnes of squares which I could pull out, and apply a mirror to it so that the same thing happens on both sides. I really don't know how to do it, and would appreciate your help.

  • Installing MoinMoin -wiki to my user directory on a server with no root access

    - by deiga
    Hello all, I've been trying to install MoinMoin -wiki on this webserver, where I have no root access. The server doesn't support wsgi, but it does support cgi/fcgi/etc. I've scoured google for a simple guide on how to accomplish this, but the only guides I found were from the year 2004 or so. Other guides always assumed that one has root access. So can anyone link a good tutorial for my question or just help me out here? Your help is appreciated :) P.S. Sorry if this is the wrong stack -page

    One of new functionalities introduced in SharePoint 2013 Preview is new theming engine. Themes that are managed by this new engine don’t use Office Theme .thmx format and can’t be created using PowerPoint like it was case before. New themes are based on set of xml files stored in Theme Gallery “15” subfolder (on relative path _catalogs/theme/15): .spcolor files  which define color palettes for components of SharePoint interface .spfont files which contain set of predefined font schemes.

  • Object detection in bitmap JavaScript canvas

    - by fallenAngel
    I want to detect clicks on canvas elements which are drawn using paths. So far I have stored element paths in a JavaScript data structure and then check the coordinates of hits which match the element's coordinates. Rendering each element path and checking the hits would be inefficient when there are a lot of elements. I believe there must be an algorithm for this kind of coordinate search, can anyone help me with this?

  • How to manage product backlog/user stories

    - by Andrew Stephens
    We're about to start a new project using Agile (using TFS), and I have a couple of "good practice" questions regarding the product backlog:- When we first start adding users stories, is it a good idea to put them in (say) a "Backlog" iteration, or just leave their iteration blank? Obviously when the time comes to start work on a US it would be moved into the appropriate iteration backlog. When breaking an epic down into smaller USs, would I simply close the original epic, as it's no longer required? Or should I create the new USs as children of the epic? (it's then someone's responsibility to close the epic once all child USs have been completed). Lastly, should the product backlog list all USs regardless of status, or only those that have not been started (i.e in my proposed "Backlog" iteration)? I realise these questions aren't life-or-death, but it would be nice to know how other people manage their product backlogs so we can organise things properly from the start.

  • Access Violation when trying to bind Vertex Object Array

    - by Paul
    I've just started digging into OpenGL and I've run into a problem trying to set a VOA. It's giving me a run-time error of : An unhandled exception of type 'System.AccessViolationException' At // Create and bind a VAO GLuint vao; glGenVertexArrays(1, &vao); glBindVertexArray(vao); I have searched the internet high and low for a solution and I haven't found one. The rest of my function looks like this: int main(array<System::String ^> ^args) { // Initialise GLFW if( !glfwInit() ) { fprintf( stderr, "Failed to initialize GLFW\n" ); return -1; } glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 0); // 4x antialiasing glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3); // We want OpenGL 3.3 glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3); glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); //We don't want the old OpenGL // Open a window and create its OpenGL context if( !glfwOpenWindow( 800, 600, 0,0,0,0, 32,0, GLFW_WINDOW ) ) { fprintf( stderr, "Failed to open GLFW window\n" ); glfwTerminate(); return -1; } // Initialize GLEW if (glewInit() != GLEW_OK) { fprintf(stderr, "Failed to initialize GLEW\n"); return -1; } glfwSetWindowTitle( "Game Engine" ); // Create and bind a VAO GLuint vao; glGenVertexArrays(1, &vao); glBindVertexArray(vao); glfwEnable( GLFW_STICKY_KEYS );

  • Methodology for designing user controls

    - by zSysop
    Hi all, I want to able to create reusable user controls within my web app and i'm wondering on how to go about doing so. Should a user controls properties be visible to a form that's using it? What's the best way to go about loading the controls on the user control from the form thats using it? Should there be a public method within the control that allows you to load it from an external form or should the user control be loaded in the page load event Is it okay to nest user controls within user controls? etc... Thanks for any advice

  • User eXperience

    - by Daniel Moth
    The last few months I have been spending a lot of time designing (and help design) the developer experience for the areas I contribute to (in future versions of Visual Studio). As a technical person who defines feature sets, it is easy to get engulfed in the pure technical side of things and ignore the details that ultimately make users "love" using the product to achieve their goal, instead of just "having to use" it. Engaging in UX design helps me escape that trap. In case you are also interested in the UX side of development, I thought I'd share an interesting site I came across: UX myths. In particular, I recommend reading myths 9, 10, 12, 13, 14, 15 and 21. Let me know if there are other UX resources you recommend… Comments about this post welcome at the original blog.
