  • how to remove all text nodes and only preserve structure information of a html page with nokogiri

    - by user58948
    I want to remove all text from html page that I load with nokogiri. For example, if a page has the following: <body><script>var x = 10;</script><div>Hello</div><div><h1>Hi</h1></div></body> I want to process it with Nokogiri and return html like the following after stripping the text like so: <body><script>var x = 10;</script><div></div><div><h1></h1></div></body> (THat is, remove the actual h1 text, text between divs, text in p elements etc, but keep the tags. also, dont remove text in the script tags.) How can I do that?

  • Javascript: move the "view point" of the browser

    - by ArchJ
    I have a page with many out-of-bounds contents and since I set body{overflow:hidden}, they are not outside the viewport. So I want to attach a function to a button which would move the PoV of the browser so that the out-of-bounds contents would come into the viewport. What I can think of now is to set body{position:relative} and use jQuery to animate() the body instead. But in terms of performance, is there a better way to achieve that?

  • Is there a way to optimise finding text items on a page (not regex)

    - by Jeepstone
    After seeing several threads rubbishing the regexp method of finding a term to match within an HTML document, I've used the Simple HTML DOM PHP parser (http://simplehtmldom.sourceforge.net/) to get the bits of text I'm after, but I want to know if my code is optimal. It feels like I'm looping too many times. Is there a way to optimise the following loop? //Get the HTML and look at the text nodes $html = str_get_html($buffer); //First we match the <body> tag as we don't want to change the <head> items foreach($html->find('body') as $body) { //Then we get the text nodes, rather than any HTML foreach($body->find('text') as $text) { //Then we match each term foreach ($terms as $term) { //Match to the terms within the text nodes $text->outertext = str_replace($term, '<span class="highlight">'.$term.'</span>', $text->outertext); } } } For example, would it make a difference to determine check if I have any matches before I start the loop maybe?

  • Should a "script" tag be allowed to remove itself?

    - by Nischal
    We've been having a discussion at our workplace on this with some for and some against the behavior. Wanted to hear views from you guys : <html> <body> <div> Test! <script> document.body.removeChild(document.getElementsByTagName('div')[0]); </script> </div> </body> </html> Should the above script work and do what it's supposed to do? First, let's see what's happening here : I have a javascript that's inside the <div> element. This javascript will delete the child node within body which happens to hold the div inside which the script itself exists. Now, the above script works fine in Firefox, Opera and IE8. But IE6 and IE7 give an alert saying they cannot open the page. Let's not debate on how IE should have handled this (they've accepted it as a bug and hence fixed it in IE8). The point here is since the 'SCRIPT' tag itself is a part of DOM, should it be allowed to do something like this? Should it even exist after such an operation? Edit: Firefox, Opera, IE9 etc. do not remove the 'script' tag if I run the above code. But, document.getElementsByTagName('script').length returns 0! To understand what I mean, add alert(document.getElementsByTagName('script').length); before and after document.body.removeChild(document.getElementsByTagName('div')[0]); in the code above.

  • How to save links with tags and parameters in TextField

    - by xRobot
    I have this simple Post model: class Post(models.Model): title = models.CharField(_('title'), max_length=60, blank=True, null=True) body = models.TextField(_('body')) blog = models.ForeignKey(Blog, related_name="posts") user = models.ForeignKey(User) I want that when I insert in the form the links, then these links are saved in the body from this form: http://www.example.com or www.example.com to this form ( with tag and rel="nofollow" parameter ): <a href="http://www.example.com" rel="nofollow">www.example.com</a> How can I do this ?

  • Sending E-Mail in C#

    - by pm_2
    I’m using .NET 3.5, and I want to automatically send a mail. I’m currently using the following: Microsoft.Office.Interop.Outlook.MailItem mailMsg = (Microsoft.Office.Interop.Outlook.MailItem)outlookApplication.CreateItem( Microsoft.Office.Interop.Outlook.OlItemType.olMailItem); mailMsg.To = recipient; mailMsg.Subject = subject; mailMsg.Body = body; mailMsg.Send(); However, I’ve found several articles that seem to imply I should be using the following method: System.Net.Mail.MailMessage mailMsg = new System.Net.Mail.MailMessage(); mailmsg.To = recipient; mailmsg.Subject = subject; mailmsg.Body = body; Can anyone tell me what the difference between the two namespaces if, and why you might want to use one over the other?

  • Adding Content to a Randomized Background

    - by user2903815
    On refresh my background image changes. I need to add a header to change with each background. How would I add an h1 tag to the php. I am unfamiliar with php but I feel like this should be an easy fix. Here's my script: <script type="text/javascript"> var bgcount = 3; function changebg() { var num = Math.ceil( Math.random() * bgcount ); document.body.background = 'bgs/'+num+'.jpg'; document.body.style.backgroundRepeat = "no-repeat"; document.body.style.backgroundAttachment = "fixed"; document.body.style.backgroundSize = "cover"; } </script> Thanks!

  • Expressjs route param as variable in main app

    - by MoDFoX
    For my app I have two route set up, app.get('/', routes.index); app.get('/:name', routes.index); I would like it to be so that if I don't specify a param, say just go to appurl.com (localhost:3000), it would load a default user, but if I do specify a param(localhost:3000/user), use that as the variable "username" in the following function (placed after my routes). (function getUser(){ var body = '', username = 'WillsonSM', options = { host: 'ws.audioscrobbler.com', port: 80, path: '/2.0/?method=user.gettopartists&user=' + username + '&format=json&limit=20&api_key=APIKEYGOESHERE' }; require('http').request(options, function(res) { res.setEncoding('utf8'); res.on('data', function(chunk) { body += chunk; }); res.on('end', function() { body = JSON.parse(body); artists = body.topartists.artist; }); }).end(); })(); Along with this I have my route set up like so: exports.index = function(req, res){ res.render('index', { title: 'LasTube' }); username = req.params.name; console.log(username); }; unfortunately setting username there to req.params.name does not seem to be accessible from the main app function. My question is: How can I set expressjs/nodejs to use the parameter set via /name when available, and just use a default - in this example "WillsonSM" if not available. I've tried taking "username" out of the main app, and just leaving it in the function, but username becomes undefined, as it is inaccessible from the route, and the app will not run. I can spit out "username" via the routes console.log, so assigning it there is not an issue, but as I am new to expressjs, I am unaware of how I should go about doing this. I have tried all I can think of and find from looking around the internet. Also, if there is a better way of doing this, or I am doing something wrong, please let me know. If I've left out any information, just throw in a comment and I'll try to address it.

  • Any way to hide elements from webview? (android)

    - by ajent
    There's a webpage I pull up with webview, however i'd like to hide the 1 text link at the top. Is there a way to do this? The link is in the body, so I can't hide the body element in whole. The webpage is all text, and one tiny image at the bottom, but the text is generated each time you load it, so I can't just copy/paste the body. Thanks

  • Ogre 3d and bullet physics interaction

    - by Tim
    I have been playing around with Ogre3d and trying to integrate bullet physics. I have previously somewhat successfully got this functionality working with irrlicht and bullet and I am trying to base this on what I had done there, but modifying it to fit with Ogre. It is working but not correctly and I would like some help to understand what it is I am doing wrong. I have a state system and when I enter the "gamestate" I call some functions such as setting up a basic scene, creating the physics simulation. I am doing that as follows. void GameState::enter() { ... // Setup Physics btBroadphaseInterface *BroadPhase = new btAxisSweep3(btVector3(-1000,-1000,-1000), btVector3(1000,1000,1000)); btDefaultCollisionConfiguration *CollisionConfiguration = new btDefaultCollisionConfiguration(); btCollisionDispatcher *Dispatcher = new btCollisionDispatcher(CollisionConfiguration); btSequentialImpulseConstraintSolver *Solver = new btSequentialImpulseConstraintSolver(); World = new btDiscreteDynamicsWorld(Dispatcher, BroadPhase, Solver, CollisionConfiguration); ... createScene(); } In the createScene method I add a light and try to setup a "ground" plane to act as the ground for things to collide with.. as follows. I expect there is issues with this as I get objects colliding with the ground but half way through it and they glitch around like crazy on collision. void GameState::createScene() { m_pSceneMgr->createLight("Light")->setPosition(75,75,75); // Physics // As a test we want a floor plane for things to collide with Ogre::Entity *ent; Ogre::Plane p; p.normal = Ogre::Vector3(0,1,0); p.d = 0; Ogre::MeshManager::getSingleton().createPlane( "FloorPlane", Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, p, 200000, 200000, 20, 20, true, 1, 9000,9000,Ogre::Vector3::UNIT_Z); ent = m_pSceneMgr->createEntity("floor", "FloorPlane"); ent->setMaterialName("Test/Floor"); Ogre::SceneNode *node = m_pSceneMgr->getRootSceneNode()->createChildSceneNode(); node->attachObject(ent); btTransform Transform; Transform.setIdentity(); Transform.setOrigin(btVector3(0,1,0)); // Give it to the motion state btDefaultMotionState *MotionState = new btDefaultMotionState(Transform); btCollisionShape *Shape = new btStaticPlaneShape(btVector3(0,1,0),0); // Add Mass btVector3 LocalInertia; Shape->calculateLocalInertia(0, LocalInertia); // CReate the rigid body object btRigidBody *RigidBody = new btRigidBody(0, MotionState, Shape, LocalInertia); // Store a pointer to the Ogre Node so we can update it later RigidBody->setUserPointer((void *) (node)); // Add it to the physics world World->addRigidBody(RigidBody); Objects.push_back(RigidBody); m_pNumEntities++; // End Physics } I then have a method to create a cube and give it rigid body physics properties. I know there will be errors here as I get the items colliding with the ground but not with each other properly. So I would appreciate some input on what I am doing wrong. void GameState::CreateBox(const btVector3 &TPosition, const btVector3 &TScale, btScalar TMass) { Ogre::Vector3 size = Ogre::Vector3::ZERO; Ogre::Vector3 pos = Ogre::Vector3::ZERO; Ogre::Vector3 scale = Ogre::Vector3::ZERO; pos.x = TPosition.getX(); pos.y = TPosition.getY(); pos.z = TPosition.getZ(); scale.x = TScale.getX(); scale.y = TScale.getY(); scale.z = TScale.getZ(); Ogre::Entity *entity = m_pSceneMgr->createEntity( "Box" + Ogre::StringConverter::toString(m_pNumEntities), "cube.mesh"); entity->setCastShadows(true); Ogre::AxisAlignedBox boundingB = entity->getBoundingBox(); size = boundingB.getSize(); //size /= 2.0f; // Only the half needed? //size *= 0.96f; // Bullet margin is a bit bigger so we need a smaller size entity->setMaterialName("Test/Cube"); Ogre::SceneNode *node = m_pSceneMgr->getRootSceneNode()->createChildSceneNode(); node->attachObject(entity); node->setPosition(pos); //node->scale(scale); // Physics btTransform Transform; Transform.setIdentity(); Transform.setOrigin(TPosition); // Give it to the motion state btDefaultMotionState *MotionState = new btDefaultMotionState(Transform); btVector3 HalfExtents(TScale.getX()*0.5f,TScale.getY()*0.5f,TScale.getZ()*0.5f); btCollisionShape *Shape = new btBoxShape(HalfExtents); // Add Mass btVector3 LocalInertia; Shape->calculateLocalInertia(TMass, LocalInertia); // CReate the rigid body object btRigidBody *RigidBody = new btRigidBody(TMass, MotionState, Shape, LocalInertia); // Store a pointer to the Ogre Node so we can update it later RigidBody->setUserPointer((void *) (node)); // Add it to the physics world World->addRigidBody(RigidBody); Objects.push_back(RigidBody); m_pNumEntities++; } Then in the GameState::update() method which which runs every frame to handle input and render etc I call an UpdatePhysics method to update the physics simulation. void GameState::UpdatePhysics(unsigned int TDeltaTime) { World->stepSimulation(TDeltaTime * 0.001f, 60); btRigidBody *TObject; for(std::vector<btRigidBody *>::iterator it = Objects.begin(); it != Objects.end(); ++it) { // Update renderer Ogre::SceneNode *node = static_cast<Ogre::SceneNode *>((*it)->getUserPointer()); TObject = *it; // Set position btVector3 Point = TObject->getCenterOfMassPosition(); node->setPosition(Ogre::Vector3((float)Point[0], (float)Point[1], (float)Point[2])); // set rotation btVector3 EulerRotation; QuaternionToEuler(TObject->getOrientation(), EulerRotation); node->setOrientation(1,(Ogre::Real)EulerRotation[0], (Ogre::Real)EulerRotation[1], (Ogre::Real)EulerRotation[2]); //node->rotate(Ogre::Vector3(EulerRotation[0], EulerRotation[1], EulerRotation[2])); } } void GameState::QuaternionToEuler(const btQuaternion &TQuat, btVector3 &TEuler) { btScalar W = TQuat.getW(); btScalar X = TQuat.getX(); btScalar Y = TQuat.getY(); btScalar Z = TQuat.getZ(); float WSquared = W * W; float XSquared = X * X; float YSquared = Y * Y; float ZSquared = Z * Z; TEuler.setX(atan2f(2.0f * (Y * Z + X * W), -XSquared - YSquared + ZSquared + WSquared)); TEuler.setY(asinf(-2.0f * (X * Z - Y * W))); TEuler.setZ(atan2f(2.0f * (X * Y + Z * W), XSquared - YSquared - ZSquared + WSquared)); TEuler *= RADTODEG; } I seem to have issues with the cubes not colliding with each other and colliding strangely with the ground. I have tried to capture the effect with the attached image. I would appreciate any help in understanding what I have done wrong. Thanks. EDIT : Solution The following code shows the changes I made to get accurate physics. void GameState::createScene() { m_pSceneMgr->createLight("Light")->setPosition(75,75,75); // Physics // As a test we want a floor plane for things to collide with Ogre::Entity *ent; Ogre::Plane p; p.normal = Ogre::Vector3(0,1,0); p.d = 0; Ogre::MeshManager::getSingleton().createPlane( "FloorPlane", Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, p, 200000, 200000, 20, 20, true, 1, 9000,9000,Ogre::Vector3::UNIT_Z); ent = m_pSceneMgr->createEntity("floor", "FloorPlane"); ent->setMaterialName("Test/Floor"); Ogre::SceneNode *node = m_pSceneMgr->getRootSceneNode()->createChildSceneNode(); node->attachObject(ent); btTransform Transform; Transform.setIdentity(); // Fixed the transform vector here for y back to 0 to stop the objects sinking into the ground. Transform.setOrigin(btVector3(0,0,0)); // Give it to the motion state btDefaultMotionState *MotionState = new btDefaultMotionState(Transform); btCollisionShape *Shape = new btStaticPlaneShape(btVector3(0,1,0),0); // Add Mass btVector3 LocalInertia; Shape->calculateLocalInertia(0, LocalInertia); // CReate the rigid body object btRigidBody *RigidBody = new btRigidBody(0, MotionState, Shape, LocalInertia); // Store a pointer to the Ogre Node so we can update it later RigidBody->setUserPointer((void *) (node)); // Add it to the physics world World->addRigidBody(RigidBody); Objects.push_back(RigidBody); m_pNumEntities++; // End Physics } void GameState::CreateBox(const btVector3 &TPosition, const btVector3 &TScale, btScalar TMass) { Ogre::Vector3 size = Ogre::Vector3::ZERO; Ogre::Vector3 pos = Ogre::Vector3::ZERO; Ogre::Vector3 scale = Ogre::Vector3::ZERO; pos.x = TPosition.getX(); pos.y = TPosition.getY(); pos.z = TPosition.getZ(); scale.x = TScale.getX(); scale.y = TScale.getY(); scale.z = TScale.getZ(); Ogre::Entity *entity = m_pSceneMgr->createEntity( "Box" + Ogre::StringConverter::toString(m_pNumEntities), "cube.mesh"); entity->setCastShadows(true); Ogre::AxisAlignedBox boundingB = entity->getBoundingBox(); // The ogre bounding box is slightly bigger so I am reducing it for // use with the rigid body. size = boundingB.getSize()*0.95f; entity->setMaterialName("Test/Cube"); Ogre::SceneNode *node = m_pSceneMgr->getRootSceneNode()->createChildSceneNode(); node->attachObject(entity); node->setPosition(pos); node->showBoundingBox(true); //node->scale(scale); // Physics btTransform Transform; Transform.setIdentity(); Transform.setOrigin(TPosition); // Give it to the motion state btDefaultMotionState *MotionState = new btDefaultMotionState(Transform); // I got the size of the bounding box above but wasn't using it to set // the size for the rigid body.

The objects now collide with the ground and each other appropriately.

  • Using rounded corners in modern websites with CSS3

    - by nikolaosk
    This is going to be the sixth post in a series of posts regarding HTML 5. You can find the other posts here , here, here , here and here.In this post I will provide a hands-on example on how to use rounded corners (rounded corners in CSS3) in your website. I think this is the feature that is most required in the new modern websites.Most websites look great with their lovely round panels and rounded corner tab style menus. We could achieve that effect earlier but we should resort to complex CSS rules and images. I will show you how to accomplish this great feature with the power of CSS 3.We will not use Javascript.Javascript is required for IE 7, IE 8 and the notorious IE 6. The best solution for implementing corners using CSS and Javascript without using images is Nifty corners cube. There are detailed information how to achieve this in the link I provided. This solution is tested in earlier vesrions of IE (IE 6,IE 7,IE 8) and Opera,Firefox,Safari. In order to be absolutely clear this is not (and could not be) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School.Another excellent resource is HTML 5 Doctor.Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here.Before I go on with the actual demo I will use the (http://www.caniuse.com) to see the support for web fonts from the latest versions of modern browsers.Please have a look at the picture below. We see that all the latest versions of modern browsers support this feature.We can see that even IE 9 supports this feature.  Let's move on with the actual demo. This is going to be a rather simple demo.I create a simple HTML 5 page. The markup follows and it is very easy to use and understand <!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">       </head>  <body>      <div id="header">      <h1>Learn cutting edge technologies</h1>    </div>        <div id="main">          <h2>HTML 5</h2>                        <p id="panel1">            HTML5 is the latest version of HTML and XHTML. The HTML standard defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML.          </p>      </div>             </body>  </html>Then I need to write the various CSS rules that style this markup. I will name it style.css   body{        line-height: 38px;        width: 1024px;        background-color:#eee;        text-align:center;      }#panel1 { margin:auto; text-align:left; background-color:#77cdef;width:400px; height:250px; padding:15px;font-size:16px;font-family:tahoma;color:#fff;border-radius: 20px;}Have a look below to see what my page looks like in IE 10. This is possible through the border-radious property. The colored panel has all four corners rounded with the same radius.We can add a border to the rounded corner panel by adding this property declaration in the #panel1,  border:4px #000 solid;We can have even better visual effects if we specify a radius for each corner.This is the updated version of the style.css. body{        line-height: 38px;        width: 1024px;        background-color:#eee;        text-align:center;      }#panel1 { margin:auto; text-align:left; background-color:#77cdef;border:4px #000 solid;width:400px; height:250px; padding:15px;font-size:16px;font-family:tahoma;color:#fff;border-top-left-radius: 20px;border-top-right-radius: 70px;border-bottom-right-radius: 20px;border-bottom-left-radius: 70px;} This is how my page looks in Firefox 15.0.1  In this final example I will show you how to style with CSS 3 (rounded corners) a horizontal navigation menu. This is the new version of the HTML markup<!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">       </head>  <body>      <div id="header">      <h1>Learn cutting edge technologies</h1>    </div>        <div id="nav"><ul><li><a class="mymenu" id="activelink" href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8934038#">Main</a></li><li><a class="mymenu" href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8934038#">HTML 5</a></li><li><a class="mymenu" href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8934038#">CSS 3</a></li><li><a class="mymenu" href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8934038#">JQuery</a></li></ul></div>        <div id="main">          <h2>HTML 5</h2>                        <p id="panel1">            HTML5 is the latest version of HTML and XHTML.

    Deployed bundle:~makyo/openstack/2/openstack, on top of 7 physical boxes and 3 virtual ones. After changing vip_iface strings to point to right devices, e.g., br0 instead of eth0, and defining "/mnt/loopback|30G", in Cinder's block-device string, am able to navigate through openstack dashboard, error free. Following http://docs.openstack.org/grizzly/openstack-compute/install/apt/content/running-an-instance.html instructions, attempted to launch cirros 0.3.1 image; however, novalist shows the instance in error state. ubuntu@node7:~$ nova --debug boot --flavor 1 --image 28bed1bc-bc1c-4533-beee-8e0428ad40dd --key_name key2 --security_group default cirros REQ: curl -i http://keyStone.IP:5000/v2.0/tokens

  • Windows Azure Mobile Services: New support for iOS apps, Facebook/Twitter/Google identity, Emails, SMS, Blobs, Service Bus and more

    - by ScottGu
    A few weeks ago I blogged about Windows Azure Mobile Services - a new capability in Windows Azure that makes it incredibly easy to connect your client and mobile applications to a scalable cloud backend. Earlier today we delivered a number of great improvements to Windows Azure Mobile Services.  New features include: iOS support – enabling you to connect iPhone and iPad apps to Mobile Services Facebook, Twitter, and Google authentication support with Mobile Services Blob, Table, Queue, and Service Bus support from within your Mobile Service Sending emails from your Mobile Service (in partnership with SendGrid) Sending SMS messages from your Mobile Service (in partnership with Twilio) Ability to deploy mobile services in the West US region All of these improvements are now live in production and available to start using immediately. Below are more details on them: iOS Support This week we delivered initial support for connecting iOS based devices (including iPhones and iPads) to Windows Azure Mobile Services.  Like the rest of our Windows Azure SDK, we are delivering the native iOS libraries to enable this under an open source (Apache 2.0) license on GitHub.  We’re excited to get your feedback on this new library through our forum and GitHub issues list, and we welcome contributions to the SDK. To create a new iOS app or connect an existing iOS app to your Mobile Service, simply select the “iOS” tab within the Quick Start view of a Mobile Service within the Windows Azure Portal – and then follow either the “Create a new iOS app” or “Connect to an existing iOS app” link below it: Clicking either of these links will expand and display step-by-step instructions for how to build an iOS application that connects with your Mobile Service: Read this getting started tutorial to walkthrough how you can build (in less than 5 minutes) a simple iOS “Todo List” app that stores data in Windows Azure.  Then follow the below tutorials to explore how to use the iOS client libraries to store data and authenticate users. Get Started with data in Mobile Services for iOS Get Started with authentication in Mobile Services for iOS Facebook, Twitter, and Google Authentication Support Our initial preview of Mobile Services supported the ability to authenticate users of mobile apps using Microsoft Accounts (formerly called Windows Live ID accounts).  This week we are adding the ability to also authenticate users using Facebook, Twitter, and Google credentials.  These are now supported with both Windows 8 apps as well as iOS apps (and a single app can support multiple forms of identity simultaneously – so you can offer your users a choice of how to login). The below tutorials walkthrough how to register your Mobile Service with an identity provider: How to register your app with Microsoft Account How to register your app with Facebook How to register your app with Twitter How to register your app with Google The tutorials above walkthrough how to obtain a client ID and a secret key from the identity provider. You can then click on the “Identity” tab of your Mobile Service (within the Windows Azure Portal) and save these values to enable server-side authentication with your Mobile Service: You can then write code within your client or mobile app to authenticate your users to the Mobile Service.  For example, below is the code you would write to have them login to the Mobile Service using their Facebook credentials: Windows Store App (using C#): var user = await App.MobileService                     .LoginAsync(MobileServiceAuthenticationProvider.Facebook); iOS app (using Objective C): UINavigationController *controller = [self.todoService.client     loginViewControllerWithProvider:@"facebook"     completion:^(MSUser *user, NSError *error) {        //... }]; Learn more about authenticating Mobile Services using Microsoft Account, Facebook, Twitter, and Google from these tutorials: Get started with authentication in Mobile Services for Windows Store (C#) Get started with authentication in Mobile Services for Windows Store (JavaScript) Get started with authentication in Mobile Services for iOS Using Windows Azure Blob, Tables and ServiceBus with your Mobile Services Mobile Services provide a simple but powerful way to add server logic using server scripts. These scripts are associated with the individual CRUD operations on your mobile service’s tables. Server scripts are great for data validation, custom authorization logic (e.g. does this user participate in this game session), augmenting CRUD operations, sending push notifications, and other similar scenarios.   Server scripts are written in JavaScript and are executed in a secure server-side scripting environment built using Node.js.  You can edit these scripts and save them on the server directly within the Windows Azure Portal: In this week’s release we have added the ability to work with other Windows Azure services from your Mobile Service server scripts.  This is supported using the existing “azure” module within the Windows Azure SDK for Node.js.  For example, the below code could be used in a Mobile Service script to obtain a reference to a Windows Azure Table (after which you could query it or insert data into it):     var azure = require('azure');     var tableService = azure.createTableService("<< account name >>",                                                 "<< access key >>"); Follow the tutorials on the Windows Azure Node.js dev center to learn more about working with Blob, Tables, Queues and Service Bus using the azure module. Sending emails from your Mobile Service In this week’s release we have also added the ability to easily send emails from your Mobile Service, building on our partnership with SendGrid. Whether you want to add a welcome email upon successful user registration, or make your app alert you of certain usage activities, you can do this now by sending email from Mobile Services server scripts. To get started, sign up for SendGrid account at http://sendgrid.com . Windows Azure customers receive a special offer of 25,000 free emails per month from SendGrid. To sign-up for this offer, or get more information, please visit http://www.sendgrid.com/azure.html . One you signed up, you can add the following script to your Mobile Service server scripts to send email via SendGrid service:     var sendgrid = new SendGrid('<< account name >>', '<< password >>');       sendgrid.send({         to: '<< enter email address here >>',         from: '<< enter from address here >>',         subject: 'New to-do item',         text: 'A new to-do was added: ' + item.text     }, function (success, message) {         if (!success) {             console.error(message);         }     }); Follow the Send email from Mobile Services with SendGrid tutorial to learn more. Sending SMS messages from your Mobile Service SMS is a key communication medium for mobile apps - it comes in handy if you want your app to send users a confirmation code during registration, allow your users to invite their friends to install your app or reach out to mobile users without a smartphone. Using Mobile Service server scripts and Twilio’s REST API, you can now easily send SMS messages to your app.  To get started, sign up for Twilio account. Windows Azure customers receive 1000 free text messages when using Twilio and Windows Azure together. Once signed up, you can add the following to your Mobile Service server scripts to send SMS messages:     var httpRequest = require('request');     var account_sid = "<< account SID >>";     var auth_token = "<< auth token >>";       // Create the request body     var body = "From=" + from + "&To=" + to + "&Body=" + message;       // Make the HTTP request to Twilio     httpRequest.post({         url: "https://" + account_sid + ":" + auth_token +              "@api.twilio.com/2010-04-01/Accounts/" + account_sid + "/SMS/Messages.json",         headers: { 'content-type': 'application/x-www-form-urlencoded' },         body: body     }, function (err, resp, body) {         console.log(body);     }); I’m excited to be speaking at the TwilioCon conference this week, and will be showcasing some of the cool scenarios you can now enable with Twilio and Windows Azure Mobile Services. Mobile Services availability in West US region Our initial preview of Windows Azure Mobile Services was only supported in the US East region of Windows Azure.  As with every Windows Azure service, overtime we will extend Mobile Services to all Windows Azure regions. With this week’s preview update we’ve added support so that you can now create your Mobile Service in the West US region as well: Summary The above features are all now live in production and are available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using Mobile Services today. Visit the Windows Azure Mobile Developer Center to learn more about how to build apps with Mobile Services. We’ll have even more new features and enhancements coming later this week – including .NET 4.5 support for Windows Azure Web Sites.  Keep an eye out on my blog for details as new features become available. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • set proxy in apache for XMPP chat

    - by Hunt
    I want to setup a proxy settings in Apache to use Facebook XMPP Chat So far I have setup ejabber server and I am able to access xmpp service using http://mydomain.com:5280/xmpp-http-bind I am able to create Jabber Account too. Now as I want to integrate Facebook XMPP chat , I want my server to sit in between client and chat.facebook.com because I want to implement Facebook chat and custom chat too. So I have read this article and come to know that I need to serve BOSH Service as a proxy in apache to access Facebook Chat service. So I don't know how to set up a proxy in a apache httpd.conf as I have tried following <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /xmpp-httpbind http://www.mydomain.com:5280/xmpp-http-bind ProxyPassReverse /xmpp-httpbind http://www.mydomain.com:5280/xmpp-http-bind But whenever I request http://www.mydomain.com:5280/xmpp-http-bind from strophe.js I am getting following response from server <body type='terminate' condition='internal-server-error' xmlns='http://jabber.org/protocol/httpbind'> BOSH module not started </body> and server log says following E(<0.567.0:ejabberd_http_bind:1239) : You are trying to use BOSH (HTTP Bind) in host "chat.facebook.com", but the module mod_http_bind is not started in that host. Configure your BOSH client to connect to the correct host, or add your desired host to the configuration, or check your 'modules' section in your ejabberd configuration file. here is my existing settings of ejabberd.cfg , but still no luck {5280, ejabberd_http, [ {access,all}, {request_handlers, [ {["pub", "archive"], mod_http_fileserver}, {["xmpp-http-bind"], mod_http_bind} ]}, captcha, http_bind, http_poll, register, web_admin ]} ]}. in a module section {mod_http_bind, [{max_inactivity, 120}]}, and whenever i fire http://www.mydomain.com:5280/xmpp-http-bind url independently am getting following message ejabberd mod_http_bind An implementation of XMPP over BOSH (XEP-0206) This web page is only informative. To use HTTP-Bind you need a Jabber/XMPP client that supports it. I have added chat.facebook.com in a list of host in ejabber.cfg as follows {hosts, ["localhost","mydomain.com","chat.facebook.com"]} and now i am getting following response <body xmlns='http://jabber.org/protocol/httpbind' sid='710da2568460512eeb546545a65980c2704d9a27' wait='300' requests='2' inactivity='120' maxpause='120' polling='2' ver='1.8' from='chat.facebook.com' secure='true' authid='1917430584' xmlns:xmpp='urn:xmpp:xbosh' xmlns:stream='http://etherx.jabber.org/streams' xmpp:version='1.0'> <stream:features xmlns:stream='http://etherx.jabber.org/streams'> <mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'> <mechanism>DIGEST-MD5</mechanism> <mechanism>PLAIN</mechanism> </mechanisms> <c xmlns='http://jabber.org/protocol/caps' hash='sha-1' node='http://www.process-one.net/en/ejabberd/' ver='yy7di5kE0syuCXOQTXNBTclpNTo='/> <register xmlns='http://jabber.org/features/iq-register'/> </stream:features> </body> if i use valid BOSH service created my jack moffit http://bosh.metajack.im:5280/xmpp-httpbind then i am getting following valid XML from facebook , but from my server i am not getting this <body xmlns='http://jabber.org/protocol/httpbind' inactivity='60' secure='true' authid='B8732AA1' content='text/xml; charset=utf-8' window='3' polling='15' sid='928073b02da55d34eb3c3464b4a40a37' requests='2' wait='300'> <stream:features xmlns:stream='http://etherx.jabber.org/streams' xmlns='jabber:client'> <mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'> <mechanism>X-FACEBOOK-PLATFORM</mechanism> <mechanism>DIGEST-MD5</mechanism> </mechanisms> </stream:features> </body> Can anyone please help me to resolve the issue

  • Apache sends plain-text response when accessing SSL-enabled site without HTTPS

    - by animuson
    I've never encountered something such as this before. I was attempting to simply redirect the page to the HTTPS version if it determined that HTTPS was off, but instead it's displaying an HTML page rather than actually redirecting; and even odder, it's displaying it as text/plain! The VirtualHost Declaration (Sort of): ServerAdmin [email protected] DocumentRoot "/path/to/files" ServerName example.com SSLEngine On SSLCertificateFile /etc/ssh/certify/example.com.crt SSLCertificateKeyFile /etc/ssh/certify/example.com.key SSLCertificateChainFile /etc/ssh/certify/sub.class1.server.ca.pem <Directory "/path/to/files/"> AllowOverride All Options +FollowSymLinks DirectoryIndex index.php Order allow,deny Allow from all </Directory> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule .* https://example.com:6161 [R=301] The Page Output: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>301 Moved Permanently</title> </head><body> <h1>Moved Permanently</h1> <p>The document has moved <a href="https://example.com:6161">here</a>.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> I've tried moving the Rewrite stuff up above the SSL stuff hoping it'd do something and nothing happens. If I view the page with via HTTPS, it displays fine like it should. It's obviously detecting that I'm trying to rewrite the path, but it's not acting. The Apache error log does not indicate anything to me that might have gone wrong. When I remove the RewriteRules: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Reason: You're speaking plain HTTP to an SSL-enabled server port.<br /> Instead use the HTTPS scheme to access this URL, please.<br /> <blockquote>Hint: <a href="https://example.com/"><b>https://example.com/</b></a></blockquote></p> <p>Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> I get the standard "you can't do this because you're not using SSL" response, which is also provided in text/plain rather than being rendered as HTML. This would make sense, it should only work for HTTPS-enabled connections, but I still want to redirect them to the HTTPS connection when it determines that it is not enabled. Thinking I could circumvent the system: I tried adding a ErrorDocument 400 https://example.com:6161 to the config file instead of using RewriteRules, and that just gave me a new message, still no cheese. <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>302 Found</title> </head><body> <h1>Found</h1> <p>The document has moved <a href="https://example.com:6161">here</a>.</p> <hr> <address>Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/1.0.0e DAV/2 Server at example.com Port 443</address> </body></html> How can I force Apache to actually redirect rather than displaying a "301" page that shows HTML in plain-text format?

  • Oracle Announces Availability of Oracle Exaskeleton with Extreme Scale

    - by J Swaroop
    Re-posting Bruce Tierney's original post - albeit a day late: I reckon this is Oracle's most interesting launch this year. Enjoy! The World’s First Human Scale Body Surface (HSBS) Designed to Toughen Spineless Wimps April 1, 2012 Building on the success of Oracle Exalogic, Oracle Exadata, and Oracle Exalytics, Oracle today announced the general availability of Oracle Exaskeleton, toughening up spineless wimps across the globe through the introduction of extreme scalability over the human body leveraging a revolutionary new technology called Human Scale Body Surface (HSBS). First Customer Ship (FCS) was received by the little known and mostly unsuccessful superhero Awkwardman. After applying Oracle Exaskeleton with extreme scale, he has since rebranded himself as Aquaman. Said Aquaman, “I used to feel so helpless in my skin…now I feel like…well…a highly scaled Engineered System thanks to Oracle!” Thousand of meek and mild individuals eagerly lined up outside Oracle Corporation’s Redwood Shores office to purchase the new Oracle Exaskeleton, with the hope of finally gaining the spine they never had. Unfortunately for the individuals, a bully was spotted allegedly kicking the sand covering the beaches of Redwood Shores into the still spineless Exaskeleton hopefuls. Supporting Quotes “Industry analysts are inquiring if Oracle Exaskeleton is a radical departure from Oracle’s traditional enterprise focus into new markets”, said Oracle representative Sabrina Twich, “Oracle has extensive expertise in unified backbone solutions for application infrastructures…this is simply a new port to the human body combining our Business Intelligence (BI) and RDBC (Remote Direct Brain Cell) technologies.” “With this release of Oracle Exaskeleton, Oracle has redefined scalability. Software and hardware vendors had it all wrong” said the Director of Oracle Exaskeleton, “Scalability for hardware is like…um…you know…so scale-ful. No, wait…can I say that again? I didn’t get that right…Scalability is hardware-on-demand with public and private…hybrid clouds, no…<long pause>…Scalability for… nevermind, I don’t want to be in this stupid press release anyway” Releases An upcoming Oracle Exaskeleton service pack release will include a new datasheet with an extensive library of three-letter acronyms (TLAs) as well as the introduction of more four-letter acronyms (FLAs) since technologies vendors have used up almost all of the 17,576 TLA permutations (TLAPs). About Oracle Oracle engineers hardware and software to work together in the cloud and in your data center. It would be an amazing coincidence if any of this is true in some secret Oracle lab, but I doubt it. Trademarks Really…you’re still reading this? Cool!
