  • Mobile location tracking on Google maps.

    - by Muhammad Umar Siddique
    I need to develop a feature for one of my website by which user can track any mobile number on Google maps just like the link below. Go o the following link and enter the 9810098109 number in textbox to find its location on map. http://wwwa.way2sms.com/jsp/LocateMobile.jsp I want to know either this page is using a third party tool to get the latitude and longitude along with service provider and draw the map accordingly or its some sort of feature provided by Google ? Is there any freeware services to get this done ?

  • How to find vector for the quaternion from X Y Z rotations

    - by can poyrazoglu
    I am creating a very simple project on OpenGL and I'm stuck with rotations. I am trying to rotate an object indepentdently in all 3 axes: X, Y, and Z. I've had sleepless nights due to the "gimbal lock" problem after rotating about one axis. I've then learned that quaternions would solve my problem. I've researched about quaternions and implementd it, but I havent't been able to convert my rotations to quaternions. For example, if I want to rotate around Z axis 90 degrees, I just create the {0,0,1} vector for my quaternion and rotate it around that axis 90 degrees using the code here: http://iphonedevelopment.blogspot.com/2009/06/opengl-es-from-ground-up-part-7_04.html (the most complicated matrix towards the bottom) That's ok for one vector, but, say, I first want to rotate 90 degrees around Z, then 90 degrees around X (just as an example). What vector do I need to pass in? How do I calculate that vector. I am not good with matrices and trigonometry (I know the basics and the general rules, but I'm just not a whiz) but I need to get this done. There are LOTS of tutorials about quaternions, but I seem to understand none (or they don't answer my question). I just need to learn to construct the vector for rotations around more than one axis combined. UPDATE: I've found this nice page about quaternions and decided to implement them this way: http://www.cprogramming.com/tutorial/3d/quaternions.html Here is my code for quaternion multiplication: void cube::quatmul(float* q1, float* q2, float* resultRef){ float w = q1[0]*q2[0] - q1[1]*q2[1] - q1[2]*q2[2] - q1[3]*q2[3]; float x = q1[0]*q2[1] + q1[1]*q2[0] + q1[2]*q2[3] - q1[3]*q2[2]; float y = q1[0]*q2[2] - q1[1]*q2[3] + q1[2]*q2[0] + q1[3]*q2[1]; float z = q1[0]*q2[3] + q1[1]*q2[2] - q1[2]*q2[1] + q1[3]*q2[0]; resultRef[0] = w; resultRef[1] = x; resultRef[2] = y; resultRef[3] = z; } Here is my code for applying a quaternion to my modelview matrix (I have a tmodelview variable that is my target modelview matrix): void cube::applyquat(){ float& x = quaternion[1]; float& y = quaternion[2]; float& z = quaternion[3]; float& w = quaternion[0]; float magnitude = sqrtf(w * w + x * x + y * y + z * z); if(magnitude == 0){ x = 1; w = y = z = 0; }else if(magnitude != 1){ x /= magnitude; y /= magnitude; z /= magnitude; w /= magnitude; } tmodelview[0] = 1 - (2 * y * y) - (2 * z * z); tmodelview[1] = 2 * x * y + 2 * w * z; tmodelview[2] = 2 * x * z - 2 * w * y; tmodelview[3] = 0; tmodelview[4] = 2 * x * y - 2 * w * z; tmodelview[5] = 1 - (2 * x * x) - (2 * z * z); tmodelview[6] = 2 * y * z - 2 * w * x; tmodelview[7] = 0; tmodelview[8] = 2 * x * z + 2 * w * y; tmodelview[9] = 2 * y * z + 2 * w * x; tmodelview[10] = 1 - (2 * x * x) - (2 * y * y); tmodelview[11] = 0; glMatrixMode(GL_MODELVIEW); glPushMatrix(); glLoadMatrixf(tmodelview); glMultMatrixf(modelview); glGetFloatv(GL_MODELVIEW_MATRIX, tmodelview); glPopMatrix(); } And my code for rotation (that I call externally), where quaternion is a class variable of the cube: void cube::rotatex(int angle){ float quat[4]; float ang = angle * PI / 180.0; quat[0] = cosf(ang / 2); quat[1] = sinf(ang/2); quat[2] = 0; quat[3] = 0; quatmul(quat, quaternion, quaternion); applyquat(); } void cube::rotatey(int angle){ float quat[4]; float ang = angle * PI / 180.0; quat[0] = cosf(ang / 2); quat[1] = 0; quat[2] = sinf(ang/2); quat[3] = 0; quatmul(quat, quaternion, quaternion); applyquat(); } void cube::rotatez(int angle){ float quat[4]; float ang = angle * PI / 180.0; quat[0] = cosf(ang / 2); quat[1] = 0; quat[2] = 0; quat[3] = sinf(ang/2); quatmul(quat, quaternion, quaternion); applyquat(); } I call, say rotatex, for 10-11 times for rotating only 1 degree, but my cube gets rotated almost 90 degrees after 10-11 times of 1 degree, which doesn't make sense. Also, after calling rotation functions in different axes, My cube gets skewed, gets 2 dimensional, and disappears (a column in modelview matrix becomes all zeros) irreversibly, which obviously shouldn't be happening with a correct implementation of the quaternions.

  • Change the get parameters in the address bar in jquery

    - by hao
    when you search on yelp, by adding additional search parameters the page does not reload. I think the results are changed based on ajax, however when you click on one of the restaruants and go back to the previous page. All of the parameters are still there. I noticed the address bars change as the parameters change. I found http://www.asual.com/jquery/address/ but it seems to add # at the end of the url. Is there a way to make it simply like index.php?xyz=1 without refreshing the page

  • CurvyCorners in Wordpress Theme only rounds some corners in IE - what am I doing wrong?

    - by user346602
    Hi, I'm implementing the CurvyCorners script on a blog I'm developing. The script works in IE on some parts of the blog, but not others. I've used the following code to add it to the functions.php file (as suggested by someone smarter than me): function load_curvy_corners() { wp_enqueue_script('curvycorners', get_bloginfo('stylesheet_directory') .'/scripts /curvycorners.src.js','','',true); } add_action('init', 'load_curvy_corners'); Here is the site I'm working on: http://www.bellissimafashions.com/blog/ The container and logo area appear rounded in IE, but the navigation area is still square and seems to take awhile to load now. I don't know if this has something to do with the fact the theme I'm using (Pure II by beathemes) has placed the left side in the footer.php?

  • When creating a dialog with jquery, how do I hide the dialog div?

    - by stormist
    I am creating a dialog like in this page: http://jqueryui.com/demos/dialog/#modal-confirmation (click view source) on the bottom is the div that gets placed in the dialog. The dialog works perfect when called by the javascript but the dialog is apparent at the bottom of the page when it loads. (minus all the styling that gets applied when it is called by the javascript function) How can I hide the div and still allow the dialog to use it? I have tried setting style="visibility:hidden" but that prevents it from being shown when called by the javascript.

  • Java App Engine - ranked counter

    - by Richard
    I understand the sharded counter, here: http://code.google.com/appengine/articles/sharding_counters.html The problem is that a simple counter will not work in my application. I am sorting my entities by a particular variable so I am returned not so much a count, but more of a rank. My current method is: SELECT COUNT(this) FROM Entity.class WHERE value <= ? Result + 1 is then the rank of the parameter in relation to the value variable in the persistent Entity objects. The limitation of this is the highest rank being returned is 1001 because count() can give a maximum of 1000. The reason I cannot store the rank on the Entity object is that the ranks are updated very often, and re-setting this rank variable would be much too costly. Any ideas on the best way to accomplish this?

  • Technologies used in Remote Administration applications(not RD)

    - by Michael
    I want to know what kind of technologies are used nowadays as underlying screen capture engine for remote administration software like VNC pcAnywhere TeamViewer RAC Remote Administrator etc.. The programming language is not so important as just to know whether a driver needs to be developed which is polling video memory 30 times per second or there are any com objects built in the Windows kernel to help doing this? I'm not interested in 3rd party components for doing this. Do I have to use DirectX facilities? Just want some start point to develop my own screen stream capture engine, which will be less CPU hog.

  • How to setup default attributes in a ruby model

    - by webdestroya
    I have a model User and when I create one, I want to pragmatically setup some API keys and what not, specifically: @user.apikey = Digest::MD5.hexdigest(BCrypt::Password.create("jibberish").to_s) I want to be able to run User.create!(:email=>"something@test.com") and have it create a user with a randomly generated API key, and secret. I currently am doing this in the controller, but when I tried to add a default user to the seeds.rb file, I am getting an SQL error (saying my apikey is null). I tried overriding the save definition, but that seemed to cause problems when I updated the model, because it would override the values. I tried overriding the initialize definition, but that is returning a nil:NilClass and breaking things. Is there a better way to do this?

  • Asynchronous email processing in Java web application

    - by Denise
    Hi everyone, I would like to implement asynchronous email sending in my web application when users register for a new account. This is so that if there is a problem or delay in sending the email message (e.g. the mail server is down or the network connection to the mail server is slow) the user won't be kept waiting for the sending to complete. My web app is built using Spring and Hibernate's implementation of JPA. What would be the best and most reliable way for me to implement asynchronous email processing in this web application? I am thinking about persisting the email information in a database table which is then regularly polled by a Quartz (http://www.opensymphony.com/quartz/) scheduled job for updates and when it finds new unsent emails, it attempts to send them. Is this a reasonable way of implementing what I want? Thanks.

  • How get Android 2.1 SDK to recognize new class: SignalStrength

    - by Doughy
    The new Android 2.1 SDK (version 7) has a new class called SignalStrength: http://developer.android.com/reference/android/telephony/SignalStrength.html I updated my SDK in Eclipse to include the 2.1 add-on, and now I am trying to use this new class. However, when I go to do an import android.telephony.SignalStrength, it can't find it. Do I have to somehow reset my project to refresh the SDK so it knows about the new libraries? How can I get it to recognize this new class? Thanks.

  • WCF to WCF communication 401, HttpClient

    - by youwhut
    I have a WCF REST service that needs to communicate with another WCF REST service. There are three websites: Default Web Site Website1 Website2 If I set up both services in Default Web Site and connect to the other (using HttpClient) using the URI http://localhost/service then everything is okay. The desired set-up is to move these two services to separate websites and rather than using the URI http://localhost/service, accessing the service via http://website1.domain.com/service still using HttpClient. I received the exception: System.ArgumentOutOfRangeException: Unauthorized (401) is not one of the following: OK (200), Created (201), Accepted (202), NonAuthoritativeInformation (203), NoContent (204), ResetContent (205), PartialContent (206) I can see this is a 401, but what is going on here? Thanks

  • TortoiseSVN 1.6.8 missing repository browser in Branch/Tag "To URL" dialog?

    - by Ash
    It seems that in TortoiseSVN 1.6.8 (on Windows), when you click the "To URL..." button in the Branch/Tag dialog, it now pops up a generic "browse for folders" dialog. It used to pop up a Repository Browser. Displaying a regular folder browser isn't much use, since you can't navigate to any of the tags/branches via the file system. Does anyone know if this is a regression or a deliberate change? Any possible workarounds (other than reverting to 1.6.7, which works fine)? Notes: I am running a repository on the local file system, which may yield different results to one going across a network. I'm definitely using an FSFS repository, so changes to BDB access via file:/// shouldn't apply. The only reference I could find to this problem is here: http://groups.google.com/group/tortoisesvn/browse_thread/thread/f3406d1bad89f1d9.

  • How to have a PHP Website tool with a version check

    - by Sara
    Hi, So I work on a small php website tool that a few people use and what I'm looking to have added is a little version checker in it. The tool is normally hosted by others on different servers/domains/whatever have you so I'm having a bit of a trouble figuring out how I can accomplish this and do so in the best possible method. So what I'm looking to do is have a webpage that just has a number on it which is the latest version. Lets say 3.2.2 is displayed on www.myawesomephptool.com/version.html in some way shape or form . Now on their installation when they open up their admin page it pulls in that 3.2.2 as the latest version to see if they are on that version. So trying to keep it simple on requirements too. Thanks for any help or suggestions, Sara

  • in TFS can we customize the merge algorithm (conflict resolution)

    - by Jennifer Zouak
    In our case we want to igonore changes in code comment headers for generated code. In Visual Studio, we can change the merge tool (GUI that pops up) and use a 3rd party tool that is able to be customized to ignore changes (http://msdn.microsoft.com/en-us/library/ms181446.aspx). Great, so a file comparison no longer highlights code comments as differences. However when it comes time to checkin, the TFS merge algorith is still prompting us to resolve conflicts. Is there any way to better inform the merge conflict resolution algorithm about which changes are actually important to us? Or can we replace the algorithm or otherwise have it subcontract its work to a 3rd party?

  • Google Bot information?

    - by Bub Bradlee
    Does anyone know any more details about google's web-crawler (aka GoogleBot)? I was curious about what it was written in (I've made a few crawlers myself and am about to make another) and if it parses images and such. I'm assuming it does somewhere along the line, b/c the images in images.google.com are all resized. It also wouldn't surprise me if it was all written in Python and if they used all their own libraries for most everything, including html/image/pdf parsing. Maybe they don't though. Maybe it's all written in C/C++. Thanks in advance-

  • How do I get google guice to inject a custom logger, say a commons-logging or log4j logger

    - by Miguel Silva
    Google guice has a built-in logger binding (http://code.google.com/p/google-guice/wiki/BuiltInBindings). But what if I want to use a commons-logging or log4j logger? Can I get guice to inject a Log created by LogFactory.getLog(CLASS.class) But having the same behavior as in built-in binding: The binding automatically sets the logger's name to the name of the class into which the Logger is being injected.. Does it even makes sense? Or shout I simply use the built-in java Logger? Or just use commons-logging without injections?

  • Inserting snippets from macros

    - by Matt
    In Visual Studio 2008 I had a macro which would insert a snippet and input today's date in one of the replacements. When I try to run this macro in VS 2010 it doesn't work. No matter how I try it will not insert a snippet. When I try the following command: DTE.ExecuteCommand("Edit.InvokeSnippetFromShortcut", "snippetName") This fails with error "Error HRESULT E_FAIL has been returned from a call to a COM component. I tried recording a new macro and when I pressed the keyboard shortcut for inserting a snippet (Ctrl+K, Ctrl+X) VS gave the error "The command Insert Snippet is not currently available." Did MS remove the ability to insert snippets from macros? If so this really is a shame because macros have functionality not found in snippets and vice versa.

    http://www.computerworld.com/s/article/9175783/Network_Solutions_sites_hacked_again One of our clients had a WordPress website on Network Solutions shared hosting. It got hacked. The resolution is to migrate the site over to one of our dedicated, private servers. This process will take 24-36 hours to complete. What do I say to my boss and client? Do I blame Network Solutions? Do I blame WordPress (we recommended it)? Do I just tell each person it is being fixed and everything is just fine?

  • What happens when I load an assembly?

    - by Baddie
    In my ASP.NET MVC application, I have the following setup: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="bin;extras"/> I have referenced assemblies located in the extras folder in the views and they have worked perfectly (using <%@ Import Namespace="myNameSpace" %>). My questions What happens when that line is called? Where is the assembly loaded? Why is it that I can't overwrite the assembly located in the extras folder that contains myNameSpace with a newer version? (I get an error saying that the assembly is "open" in another program) Is there a way to overwrite the assembly with a newer version without having the application restart?

  • Django BigInteger auto-increment field as primary key?

    - by Alex Letoosh
    Hi all, I'm currently building a project which involves a lot of collective intelligence. Every user visiting the web site gets created a unique profile and their data is later used to calculate best matches for themselves and other users. By default, Django creates an INT(11) id field to handle models primary keys. I'm concerned with this being overflown very quickly (i.e. ~2.4b devices visiting the page without prior cookie set up). How can I change it to be represented as BIGINT in MySQL and long() inside Django itself? I've found I could do the following (http://docs.djangoproject.com/en/dev/ref/models/fields/#bigintegerfield): class MyProfile(models.Model): id = BigIntegerField(primary_key=True) But is there a way to make it autoincrement, like usual id fields? Additionally, can I make it unsigned so that I get more space to fill in? Thanks!

  • How can I get the GUID from a PDB file?

    Hello, Does anyone know how to get the GUID from a PDB file? I'm using Microsoft's Debug Interface Access SDK http://msdn.microsoft.com/en-us/library/f0756hat.aspx and getting E_PDB_INVALID_SIG when passing in the GUID i expect when trying to load the PDB. I'd just like to know the GUID of the PDB so I can be certain that it's mismatching and not just a PDB that's perhaps corrupted somehow. Is there a tool that can do this? I've tried dia2dump and dumpbin, but with no joy... Many thanks, thoughton.

  • Cannot format first column in WxPython's ListCtrl

    If I set the format of the first column in a ListCtrl to align centre (or align right) nothing happens. It works for the other columns.
