  • How to schedule a task X minutes after Windows Server 2003 starts?

    - by Joe Schmoe
    How to schedule a task X minutes after Windows Server 2003 starts? In "Scheduled Tasks" one can specify "When my computer starts" but I see no way to specify delay. What I am trying to achieve: there is a service (JIRA) that even though dependent on SQL Server service still doesn't wait long enough for SQL Server to become fully operational. So JIRA service fails to connect to the database and needs to be restarted manually after each server reboot. My plan is to add "SC stop" and "SC start" commands for JIRA service 3 minutes after server starts.

    We provide Email Marketing service through our online App. We have about 30 customers. And each one has it's own mailling list (5k to 20k emails each). What we really want is to distribute email's delivery between 2 or more servers. I was wondering What kind of aproach/solutions MailChimp , Constant Contact uses to provide a great service ? use many servers ? many IPs ? Our spam policy suspends ANY user/customer that gets 10% bounced .

  • Delay keyboard input help

    - by Stradigos
    I'm so close! I'm using the XNA Game State Management example found here and trying to modify how it handles input so I can delay the key/create an input buffer. In GameplayScreen.cs I've declared a double called elapsedTime and set it equal to 0. In the HandleInput method I've changed the Key.Right button press to: if (keyboardState.IsKeyDown(Keys.Left)) movement.X -= 50; if (keyboardState.IsKeyDown(Keys.Right)) { elapsedTime -= gameTime.ElapsedGameTime.TotalMilliseconds; if (elapsedTime <= 0) { movement.X += 50; elapsedTime = 10; } } else { elapsedTime = 0; } The pseudo code: If the right arrow key is not pressed set elapsedTime to 0. If it is pressed, the elapsedTime equals itself minus the milliseconds since the last frame. If the difference then equals 0 or less, move the object 50, and then set the elapsedTime to 10 (the delay). If the key is being held down elapsedTime should never be set to 0 via the else. Instead, after elapsedTime is set to 10 after a successful check, the elapsedTime should get lower and lower because it's being subtracted by the TotalMilliseconds. When that reaches 0, it successfully passes the check again and moves the object once more. The problem is, it moves the object once per press but doesn't work if you hold it down. Can anyone offer any sort of tip/example/bit of knowledge towards this? Thanks in advance, it's been driving me nuts. In theory I thought this would for sure work. CLARIFICATION Think of a grid when your thinking about how I want the block to move. Instead of just fluidly moving across the screen, it's moving by it's width (sorta jumping) to the next position. If I hold down the key, it races across the screen. I want to slow this whole process down so that holding the key creates an X millisecond delay between it 'jumping'/moving by it's width. EDIT: Turns out gameTime.ElapsedGameTime.TotalMilliseconds is returning 0... all of the time. I have no idea why.

  • Getting the executed output of an aspx page after a short delay

    - by Ankur
    Hi all, I have an aspx page which has some javascript code like <script> setTimeout("document.write('" + place.address + "');",1); </script> As it is clear from the code it will going to write something on the page after a very short delay of 1 ms. I have created an another page to get the page executed by some query string and get its output. The problem is I can not avoid the delay as simply writing document.write(place.address); will not print anything as it takes a little time to get values so if i set it in setTimeout for delayed output of 1 ms it always return me a value If I request the output from another page using System.Net.WebClient wc = new System.Net.WebClient(); System.IO.StreamReader sr = new System.IO.StreamReader(wc.OpenRead("http://localhost:4859/Default.aspx?lat=" + lat + "&lng=" + lng)); string strData = sr.ReadToEnd(); I get the source code of the document instead of the desired output can anyone help me out for either avoiding that delay or else delayed the client request ouput so that i get a desired value not the source code The js on default.aspx is <script type="text/javascript"> var geocoder; var address; function initialize() { geocoder = new GClientGeocoder(); var qs=new Querystring(); if(qs.get("lat") && qs.get("lng")) { geocoder.getLocations(new GLatLng(qs.get("lat"),qs.get("lng")),showAddress); } else { document.write("Invalid Access Or Not valid lat long is provided."); } } function getAddress(overlay, latlng) { if (latlng != null) { address = latlng; geocoder.getLocations(latlng, showAddress); } } function showAddress(r) { place = r.Placemark[0]; setTimeout("document.write('" + place.address + "');",1); //document.write(place.address); } </script> and the code on requestClient.aspx is as System.Net.WebClient wc = new System.Net.WebClient(); System.IO.StreamReader sr = new System.IO.StreamReader(wc.OpenRead("http://localhost:4859/Default.aspx?lat=" + lat + "&lng=" + lng)); string strData = sr.ReadToEnd();

  • Javascript library to reliably delay-load java applets

    - by paleozogt
    I'd like to delay-load a Java Applet in the same way that SwfObject loads Flash SWFs-- you supply it a div id and it replaces the div's contents. This would allow the whole page to load before the Applet starts. However, I'd also like to use a best-practices Javascript library like deployJava.js or applet-fu. The problem with these libraries is that they only use document.writeln-- if you use them after the DOM loads they will clobber the page. Are there any Applet-loading JavaScript libraries that allow for delay-loading?

  • Workflow 4.0 code activities calling other activites (persist, delay etc)

    - by Lygpt
    I have a bunch of Workflow foundation 4.0 RC code activities that consume web services and talk to databases that I want to add some error handling in. I would really like to be able to attempt to call my web service / db, catch any faults such as a communication failure and then retry the same operation in 1 hours time (after I have logged the exception). Is there a way of doing something like this? protected override void Execute(CodeActivityContext context) { Persist(); // I would like to invoke the persist activity like this if (!AttemptServiceCall()) { // I would like to invoke a delay activity like this Delay(new TimeSpan(0, 30, 0)); // wait 30 mins before trying again Execute(context); // call this activity again } } private bool AttemptServiceCall() { bool serviceCallSuccessful = true; try { myService.InvokeSomeMethod(); } catch (CommunicationException ex) { myEventLogger.Log(ex); serviceCallSuccessful = false; } return serviceCallSuccessful; }

  • The impossible inline Javascript delay/sleep

    - by trex005
    There is a JavaScript function, of which I have zero control of the code, which calls a function that I wrote. My function uses DOM to generate an iFrame, defines it's src and then appends it to another DOM element. However, before my function returns, and thus allows continued execution of the containing function, it is imperative that the iFrame be fully loaded. Here are the things that I have tried and why they do not work : 1. The SetTimeout option : 99.999% of the time, this is THE answer. As a matter of fact, in the past decade that I have been mentoring in JavaScript, I have always insisted that code could always be refactored to use this option, and never believed a scenario existed where that was not the case. Well, I finally found one! The problem is that because my function is being called inline, if the very next line is executed before my iFrame finishes loading, it totally neuters my script, and since the moment my script completes, the external script continues. A callback of sorts will not work 2. The "Do nothing" loop :This option you use while(//iFrame is not loaded){//do nothing}. In theory this would not return until the frame is loaded. The problem is that since this hogs all the resources, the iFrame never loads. This trick, although horribly unprofessional, dirty etc. will work when you just need an inline delay, but since I require an external thread to complete, it will not.In FF, after a few seconds, it pauses the script and an alert pops up stating that there is an unresponsive script. While that alert is up, the iFrame is able to load, and then my function is able to return, but having the browser frozen for 10 seconds, and then requiring the user to correctly dismiss an error is a no go. 3. The model dialogue : I was inspired by the fact that the FF popup allowed the iFrame to load while halting the execution of the function, and thinking about it, I realized that it is because the modal dialogue, is a way of halting execution yet allowing other threads to continue! Brilliant, so I decided to try other modal options. Things like alert() work beautifully! When it pops up, even if only up for 1/10th of a second, the iFrame is able to complete, and all works great. And just in case the 1/10 of a second is not sufficient, I can put the model dialogue in the while loop from solution 2, and it would ensure that the iFrame is loaded in time. Sweet right? Except for the fact that I now have to pop up a very unprofessional dialogue for the user to dismiss in order to run my script. I fought with myself about this cost/benefit of this action, but then I encountered a scenario where my code was called 10 times on a single page! Having to dismiss 10 alerts before acessing a page?! That reminds me of the late 90s script kiddie pages, and is NOT an option. 4. A gazillion other delay script out there:There are about 10 jQuery delay or sleep functions, some of them actually quite cleverly developed, but none worked. A few prototype options, and again, none I found could do it! A dozen or so other libraries and frameworks claimed they had what I needed, but alas they all conspired to give me false hope. I am convinced that since a built in model dialogue can halt execution, while allowing other threads to continue, there must be some code accessible way to do the same thing with out user input. The Code is literally thousands upon thousands of lines and is proprietary, so I wrote this little example of the problem for you to work with. It is important to note the ONLY code you are able to change is in the onlyThingYouCanChange function Test File : <html> <head> </head> </html> <body> <div id='iFrameHolder'></div> <script type='text/javascript'> function unChangeableFunction() { new_iFrame = onlyThingYouCanChange(document.getElementById('iFrameHolder')); new_iFrame_doc = (new_iFrame.contentWindow || new_iFrame.contentDocument); if(new_iFrame_doc.document)new_iFrame_doc=new_iFrame_doc.document; new_iFrame_body = new_iFrame_doc.body; if(new_iFrame_body.innerHTML != 'Loaded?') { //The world explodes!!! alert('you just blew up the world! Way to go!'); } else { alert('wow, you did it! Way to go!'); } } var iFrameLoaded = false; function onlyThingYouCanChange(objectToAppendIFrameTo) { iFrameLoaded = false; iframe=document.createElement('iframe'); iframe.onload = new Function('iFrameLoaded = true'); iframe.src = 'blank_frame.html'; //Must use an HTML doc on the server because there is a very specific DOM structure that must be maintained. objectToAppendIFrameTo.appendChild(iframe); var it = 0; while(!iFrameLoaded) //I put the limit on here so you don't { //If I was able to put some sort of delay here that paused the exicution of the script, but did not halt all other browser threads, and did not require user interaction we'd be golden! //alert('test'); //This would work if it did not require user interaction! } return iframe; } unChangeableFunction(); </script> </body> blank_frame.html : <html> <head> </head> <body style='margin:0px'>Loaded?</body> </html>

  • Delay-Load equivalent in unix based systems

    - by saran
    What is the delay load equivalent in unix based system. I have a code foo.cpp, While compiling with gcc I link it to shared objects(totally three .so files are there.).Each of the .so file for different option. ./foo -v needs libversion.so ./foo -update needs libupdate.so I need the symbol for those libraries should be resolved only at the run time. ./foo -v should not break even if libupdate.so library is not there. It is working in windows using the delay load option(in properties of dll). What is its equivalent in unix systems. Will '-lazy' option does the same in UNIX?. If so,Where to include this option? (in makefile or with linker ld). I am not good in unix. Please help me.. Thanks in advance.

  • In jquery Set a delay to fade out or fadeout right away on click

    - by JClu
    I am trying to right a script for a notification popup. I wan't the popup to fade out after X seconds or fadeout when the user clicks on the message. I can get both effects to work individually but when I try to combine them fadeOut works. This is my code so far: function notify(data, type) { switch(type) { case "success": $('#notify').html(data) .removeAttr("style") .addClass('notifySuccess') .click(function() { $("#notify").fadeOut(); }) .delay(5000).fadeOut(); break; case "error": $('#notify').html(data) .removeAttr("style") .addClass('notifyFailure') .click(function() { $("#notify").fadeOut(); }) .delay(5000).fadeOut(); break; } }

  • Using a .delay() function before .css() manipulation in jQuery

    - by Fabian
    I have this: var $ul = $(this).children("ul"); $ul.animate({opacity: 0}, 1000); $ul.delay(1000).css("display", "none") It's for my dropdown menu, and I want it to fade off before it disappears using the display: none; CSS property. However it appears that the .delay() cannot be used on the .css(); it doesn't work, the $ul just disappears right away. I can't use $ul.animate({opacity: 0, display: "none"}, 1000); either.

  • Perform tasks with delay, without delaying web response (ASP.NET)

    - by Tomas Lycken
    I'm working on a feature that needs to send two text messages with a 30 second delay, and it is crucial that both text messages are sent. Currently, this feature is built with ajax requests, that are sent with a 30 second javascript delay, but since this requires the user to have his browser open and left on the same page for at least 30 seconds, it is not a method I like. Instead, I have tried to solve this with threading. This is what I've done: Public Shared Sub Larma() Dim thread As New System.Threading.Thread(AddressOf Larma_Thread) thread.Start() End Sub Private Shared Sub Larma_Thread() StartaLarm() Thread.Sleep(1000 * 30) StoppaLarm() End Sub A web handler calls Larma(), and StartaLarm() and StoppaLarm() are the methods that send the first and second text messages respectively. However, I only get the first text message delivered - the second is never sent. Am I doing something wrong here? I have no deep understanding of how threading works in ASP.NET, so please let me know how to accomplish this.

  • Windows Azure: Import/Export Hard Drives, VM ACLs, Web Sockets, Remote Debugging, Continuous Delivery, New Relic, Billing Alerts and More

    - by ScottGu
    Two weeks ago we released a giant set of improvements to Windows Azure, as well as a significant update of the Windows Azure SDK. This morning we released another massive set of enhancements to Windows Azure.  Today’s new capabilities include: Storage: Import/Export Hard Disk Drives to your Storage Accounts HDInsight: General Availability of our Hadoop Service in the cloud Virtual Machines: New VM Gallery, ACL support for VIPs Web Sites: WebSocket and Remote Debugging Support Notification Hubs: Segmented customer push notification support with tag expressions TFS & GIT: Continuous Delivery Support for Web Sites + Cloud Services Developer Analytics: New Relic support for Web Sites + Mobile Services Service Bus: Support for partitioned queues and topics Billing: New Billing Alert Service that sends emails notifications when your bill hits a threshold you define All of these improvements are now available to use immediately (note that some features are still in preview).  Below are more details about them. Storage: Import/Export Hard Disk Drives to Windows Azure I am excited to announce the preview of our new Windows Azure Import/Export Service! The Windows Azure Import/Export Service enables you to move large amounts of on-premises data into and out of your Windows Azure Storage accounts. It does this by enabling you to securely ship hard disk drives directly to our Windows Azure data centers. Once we receive the drives we’ll automatically transfer the data to or from your Windows Azure Storage account.  This enables you to import or export massive amounts of data more quickly and cost effectively (and not be constrained by available network bandwidth). Encrypted Transport Our Import/Export service provides built-in support for BitLocker disk encryption – which enables you to securely encrypt data on the hard drives before you send it, and not have to worry about it being compromised even if the disk is lost/stolen in transit (since the content on the transported hard drives is completely encrypted and you are the only one who has the key to it).  The drive preparation tool we are shipping today makes setting up bitlocker encryption on these hard drives easy. How to Import/Export your first Hard Drive of Data You can read our Getting Started Guide to learn more about how to begin using the import/export service.  You can create import and export jobs via the Windows Azure Management Portal as well as programmatically using our Server Management APIs. It is really easy to create a new import or export job using the Windows Azure Management Portal.  Simply navigate to a Windows Azure storage account, and then click the new Import/Export tab now available within it (note: if you don’t have this tab make sure to sign-up for the Import/Export preview): Then click the “Create Import Job” or “Create Export Job” commands at the bottom of it.  This will launch a wizard that easily walks you through the steps required: For more comprehensive information about Import/Export, refer to Windows Azure Storage team blog.  You can also send questions and comments to the [email protected] email address. We think you’ll find this new service makes it much easier to move data into and out of Windows Azure, and it will dramatically cut down the network bandwidth required when working on large data migration projects.  We hope you like it. HDInsight: 100% Compatible Hadoop Service in the Cloud Last week we announced the general availability release of Windows Azure HDInsight. HDInsight is a 100% compatible Hadoop service that allows you to easily provision and manage Hadoop clusters for big data processing in Windows Azure.  This release is now live in production, backed by an enterprise SLA, supported 24x7 by Microsoft Support, and is ready to use for production scenarios. HDInsight allows you to use Apache Hadoop tools, such as Pig and Hive, to process large amounts of data in Windows Azure Blob Storage. Because data is stored in Windows Azure Blob Storage, you can choose to dynamically create Hadoop clusters only when you need them, and then shut them down when they are no longer required (since you pay only for the time the Hadoop cluster instances are running this provides a super cost effective way to use them).  You can create Hadoop clusters using either the Windows Azure Management Portal (see below) or using our PowerShell and Cross Platform Command line tools: The import/export hard drive support that came out today is a perfect companion service to use with HDInsight – the combination allows you to easily ingest, process and optionally export a limitless amount of data.  We’ve also integrated HDInsight with our Business Intelligence tools, so users can leverage familiar tools like Excel in order to analyze the output of jobs.  You can find out more about how to get started with HDInsight here. Virtual Machines: VM Gallery Enhancements Today’s update of Windows Azure brings with it a new Virtual Machine gallery that you can use to create new VMs in the cloud.  You can launch the gallery by doing New->Compute->Virtual Machine->From Gallery within the Windows Azure Management Portal: The new Virtual Machine Gallery includes some nice enhancements that make it even easier to use: Search: You can now easily search and filter images using the search box in the top-right of the dialog.  For example, simply type “SQL” and we’ll filter to show those images in the gallery that contain that substring. Category Tree-view: Each month we add more built-in VM images to the gallery.  You can continue to browse these using the “All” view within the VM Gallery – or now quickly filter them using the category tree-view on the left-hand side of the dialog.  For example, by selecting “Oracle” in the tree-view you can now quickly filter to see the official Oracle supplied images. MSDN and Supported checkboxes: With today’s update we are also introducing filters that makes it easy to filter out types of images that you may not be interested in. The first checkbox is MSDN: using this filter you can exclude any image that is not part of the Windows Azure benefits for MSDN subscribers (which have highly discounted pricing - you can learn more about the MSDN pricing here). The second checkbox is Supported: this filter will exclude any image that contains prerelease software, so you can feel confident that the software you choose to deploy is fully supported by Windows Azure and our partners. Sort options: We sort gallery images by what we think customers are most interested in, but sometimes you might want to sort using different views. So we’re providing some additional sort options, like “Newest,” to customize the image list for what suits you best. Pricing information: We now provide additional pricing information about images and options on how to cost effectively run them directly within the VM Gallery. The above improvements make it even easier to use the VM Gallery and quickly create launch and run Virtual Machines in the cloud. Virtual Machines: ACL Support for VIPs A few months ago we exposed the ability to configure Access Control Lists (ACLs) for Virtual Machines using Windows PowerShell cmdlets and our Service Management API. With today’s release, you can now configure VM ACLs using the Windows Azure Management Portal as well. You can now do this by clicking the new Manage ACL command in the Endpoints tab of a virtual machine instance: This will enable you to configure an ordered list of permit and deny rules to scope the traffic that can access your VM’s network endpoints. For example, if you were on a virtual network, you could limit RDP access to a Windows Azure virtual machine to only a few computers attached to your enterprise. Or if you weren’t on a virtual network you could alternatively limit traffic from public IPs that can access your workloads: Here is the default behaviors for ACLs in Windows Azure: By default (i.e. no rules specified), all traffic is permitted. When using only Permit rules, all other traffic is denied. When using only Deny rules, all other traffic is permitted. When there is a combination of Permit and Deny rules, all other traffic is denied. Lastly, remember that configuring endpoints does not automatically configure them within the VM if it also has firewall rules enabled at the OS level.  So if you create an endpoint using the Windows Azure Management Portal, Windows PowerShell, or REST API, be sure to also configure your guest VM firewall appropriately as well. Web Sites: Web Sockets Support With today’s release you can now use Web Sockets with Windows Azure Web Sites.  This feature enables you to easily integrate real-time communication scenarios within your web based applications, and is available at no extra charge (it even works with the free tier).  Higher level programming libraries like SignalR and socket.io are also now supported with it. You can enable Web Sockets support on a web site by navigating to the Configure tab of a Web Site, and by toggling Web Sockets support to “on”: Once Web Sockets is enabled you can start to integrate some really cool scenarios into your web applications.  Check out the new SignalR documentation hub on www.asp.net to learn more about some of the awesome scenarios you can do with it. Web Sites: Remote Debugging Support The Windows Azure SDK 2.2 we released two weeks ago introduced remote debugging support for Windows Azure Cloud Services. With today’s Windows Azure release we are extending this remote debugging support to also work with Windows Azure Web Sites. With live, remote debugging support inside of Visual Studio, you are able to have more visibility than ever before into how your code is operating live in Windows Azure. It is now super easy to attach the debugger and quickly see what is going on with your application in the cloud. Remote Debugging of a Windows Azure Web Site using VS 2013 Enabling the remote debugging of a Windows Azure Web Site using VS 2013 is really easy.  Start by opening up your web application’s project within Visual Studio. Then navigate to the “Server Explorer” tab within Visual Studio, and click on the deployed web-site you want to debug that is running within Windows Azure using the Windows Azure->Web Sites node in the Server Explorer.  Then right-click and choose the “Attach Debugger” option on it: When you do this Visual Studio will remotely attach the debugger to the Web Site running within Windows Azure.  The debugger will then stop the web site’s execution when it hits any break points that you have set within your web application’s project inside Visual Studio.  For example, below I set a breakpoint on the “ViewBag.Message” assignment statement within the HomeController of the standard ASP.NET MVC project template.  When I hit refresh on the “About” page of the web site within the browser, the breakpoint was triggered and I am now able to debug the app remotely using Visual Studio: Note above how we can debug variables (including autos/watchlist/etc), as well as use the Immediate and Command Windows. In the debug session above I used the Immediate Window to explore some of the request object state, as well as to dynamically change the ViewBag.Message property.  When we click the the “Continue” button (or press F5) the app will continue execution and the Web Site will render the content back to the browser.  This makes it super easy to debug web apps remotely. Tips for Better Debugging To get the best experience while debugging, we recommend publishing your site using the Debug configuration within Visual Studio’s Web Publish dialog. This will ensure that debug symbol information is uploaded to the Web Site which will enable a richer debug experience within Visual Studio.  You can find this option on the Web Publish dialog on the Settings tab: When you ultimately deploy/run the application in production we recommend using the “Release” configuration setting – the release configuration is memory optimized and will provide the best production performance.  To learn more about diagnosing and debugging Windows Azure Web Sites read our new Troubleshooting Windows Azure Web Sites in Visual Studio guide. Notification Hubs: Segmented Push Notification support with tag expressions In August we announced the General Availability of Windows Azure Notification Hubs - a powerful Mobile Push Notifications service that makes it easy to send high volume push notifications with low latency from any mobile app back-end.  Notification hubs can be used with any mobile app back-end (including ones built using our Mobile Services capability) and can also be used with back-ends that run in the cloud as well as on-premises. Beginning with the initial release, Notification Hubs allowed developers to send personalized push notifications to both individual users as well as groups of users by interest, by associating their devices with tags representing the logical target of the notification. For example, by registering all devices of customers interested in a favorite MLB team with a corresponding tag, it is possible to broadcast one message to millions of Boston Red Sox fans and another message to millions of St. Louis Cardinals fans with a single API call respectively. New support for using tag expressions to enable advanced customer segmentation With today’s release we are adding support for even more advanced customer targeting.  You can now identify customers that you want to send push notifications to by defining rich tag expressions. With tag expressions, you can now not only broadcast notifications to Boston Red Sox fans, but take that segmenting a step farther and reach more granular segments. This opens up a variety of scenarios, for example: Offers based on multiple preferences—e.g. send a game day vegetarian special to users tagged as both a Boston Red Sox fan AND a vegetarian Push content to multiple segments in a single message—e.g. rain delay information only to users who are tagged as either a Boston Red Sox fan OR a St. Louis Cardinal fan Avoid presenting subsets of a segment with irrelevant content—e.g. season ticket availability reminder to users who are tagged as a Boston Red Sox fan but NOT also a season ticket holder To illustrate with code, consider a restaurant chain app that sends an offer related to a Red Sox vs Cardinals game for users in Boston. Devices can be tagged by your app with location tags (e.g. “Loc:Boston”) and interest tags (e.g. “Follows:RedSox”, “Follows:Cardinals”), and then a notification can be sent by your back-end to “(Follows:RedSox || Follows:Cardinals) && Loc:Boston” in order to deliver an offer to all devices in Boston that follow either the RedSox or the Cardinals. This can be done directly in your server backend send logic using the code below: var notification = new WindowsNotification(messagePayload); hub.SendNotificationAsync(notification, "(Follows:RedSox || Follows:Cardinals) && Loc:Boston"); In your expressions you can use all Boolean operators: AND (&&), OR (||), and NOT (!).  Some other cool use cases for tag expressions that are now supported include: Social: To “all my group except me” - group:id && !user:id Events: Touchdown event is sent to everybody following either team or any of the players involved in the action: Followteam:A || Followteam:B || followplayer:1 || followplayer:2 … Hours: Send notifications at specific times. E.g. Tag devices with time zone and when it is 12pm in Seattle send to: GMT8 && follows:thaifood Versions and platforms: Send a reminder to people still using your first version for Android - version:1.0 && platform:Android For help on getting started with Notification Hubs, visit the Notification Hub documentation center.  Then download the latest NuGet package (or use the Notification Hubs REST APIs directly) to start sending push notifications using tag expressions.  They are really powerful and enable a bunch of great new scenarios. TFS & GIT: Continuous Delivery Support for Web Sites + Cloud Services With today’s Windows Azure release we are making it really easy to enable continuous delivery support with Windows Azure and Team Foundation Services.  Team Foundation Services is a cloud based offering from Microsoft that provides integrated source control (with both TFS and Git support), build server, test execution, collaboration tools, and agile planning support.  It makes it really easy to setup a team project (complete with automated builds and test runners) in the cloud, and it has really rich integration with Visual Studio. With today’s Windows Azure release it is now really easy to enable continuous delivery support with both TFS and Git based repositories hosted using Team Foundation Services.  This enables a workflow where when code is checked in, built successfully on an automated build server, and all tests pass on it – I can automatically have the app deployed on Windows Azure with zero manual intervention or work required. The below screen-shots demonstrate how to quickly setup a continuous delivery workflow to Windows Azure with a Git-based ASP.NET MVC project hosted using Team Foundation Services. Enabling Continuous Delivery to Windows Azure with Team Foundation Services The project I’m going to enable continuous delivery with is a simple ASP.NET MVC project whose source code I’m hosting using Team Foundation Services.  I did this by creating a “SimpleContinuousDeploymentTest” repository there using Git – and then used the new built-in Git tooling support within Visual Studio 2013 to push the source code to it.  Below is a screen-shot of the Git repository hosted within Team Foundation Services: I can access the repository within Visual Studio 2013 and easily make commits with it (as well as branch, merge and do other tasks).  Using VS 2013 I can also setup automated builds to take place in the cloud using Team Foundation Services every time someone checks in code to the repository: The cool thing about this is that I don’t have to buy or rent my own build server – Team Foundation Services automatically maintains its own build server farm and can automatically queue up a build for me (for free) every time someone checks in code using the above settings.  This build server (and automated testing) support now works with both TFS and Git based source control repositories. Connecting a Team Foundation Services project to Windows Azure Once I have a source repository hosted in Team Foundation Services with Automated Builds and Testing set up, I can then go even further and set it up so that it will be automatically deployed to Windows Azure when a source code commit is made to the repository (assuming the Build + Tests pass).  Enabling this is now really easy.  To set this up with a Windows Azure Web Site simply use the New->Compute->Web Site->Custom Create command inside the Windows Azure Management Portal.  This will create a dialog like below.  I gave the web site a name and then made sure the “Publish from source control” checkbox was selected: When we click next we’ll be prompted for the location of the source repository.  We’ll select “Team Foundation Services”: Once we do this we’ll be prompted for our Team Foundation Services account that our source repository is hosted under (in this case my TFS account is “scottguthrie”): When we click the “Authorize Now” button we’ll be prompted to give Windows Azure permissions to connect to the Team Foundation Services account.  Once we do this we’ll be prompted to pick the source repository we want to connect to.  Starting with today’s Windows Azure release you can now connect to both TFS and Git based source repositories.  This new support allows me to connect to the “SimpleContinuousDeploymentTest” respository we created earlier: Clicking the finish button will then create the Web Site with the continuous delivery hooks setup with Team Foundation Services.  Now every time someone pushes source control to the repository in Team Foundation Services, it will kick off an automated build, run all of the unit tests in the solution , and if they pass the app will be automatically deployed to our Web Site in Windows Azure.  You can monitor the history and status of these automated deployments using the Deployments tab within the Web Site: This enables a really slick continuous delivery workflow, and enables you to build and deploy apps in a really nice way. Developer Analytics: New Relic support for Web Sites + Mobile Services With today’s Windows Azure release we are making it really easy to enable Developer Analytics and Monitoring support with both Windows Azure Web Site and Windows Azure Mobile Services.  We are partnering with New Relic, who provide a great dev analytics and app performance monitoring offering, to enable this - and we have updated the Windows Azure Management Portal to make it really easy to configure. Enabling New Relic with a Windows Azure Web Site Enabling New Relic support with a Windows Azure Web Site is now really easy.  Simply navigate to the Configure tab of a Web Site and scroll down to the “developer analytics” section that is now within it: Clicking the “add-on” button will display some additional UI.  If you don’t already have a New Relic subscription, you can click the “view windows azure store” button to obtain a subscription (note: New Relic has a perpetually free tier so you can enable it even without paying anything): Clicking the “view windows azure store” button will launch the integrated Windows Azure Store experience we have within the Windows Azure Management Portal.  You can use this to browse from a variety of great add-on services – including New Relic: Select “New Relic” within the dialog above, then click the next button, and you’ll be able to choose which type of New Relic subscription you wish to purchase.  For this demo we’ll simply select the “Free Standard Version” – which does not cost anything and can be used forever:  Once we’ve signed-up for our New Relic subscription and added it to our Windows Azure account, we can go back to the Web Site’s configuration tab and choose to use the New Relic add-on with our Windows Azure Web Site.  We can do this by simply selecting it from the “add-on” dropdown (it is automatically populated within it once we have a New Relic subscription in our account): Clicking the “Save” button will then cause the Windows Azure Management Portal to automatically populate all of the needed New Relic configuration settings to our Web Site: Deploying the New Relic Agent as part of a Web Site The final step to enable developer analytics using New Relic is to add the New Relic runtime agent to our web app.  We can do this within Visual Studio by right-clicking on our web project and selecting the “Manage NuGet Packages” context menu: This will bring up the NuGet package manager.  You can search for “New Relic” within it to find the New Relic agent.  Note that there is both a 32-bit and 64-bit edition of it – make sure to install the version that matches how your Web Site is running within Windows Azure (note: you can configure your Web Site to run in either 32-bit or 64-bit mode using the Web Site’s “Configuration” tab within the Windows Azure Management Portal): Once we install the NuGet package we are all set to go.  We’ll simply re-publish the web site again to Windows Azure and New Relic will now automatically start monitoring the application Monitoring a Web Site using New Relic Now that the application has developer analytics support with New Relic enabled, we can launch the New Relic monitoring portal to start monitoring the health of it.  We can do this by clicking on the “Add Ons” tab in the left-hand side of the Windows Azure Management Portal.  Then select the New Relic add-on we signed-up for within it.  The Windows Azure Management Portal will provide some default information about the add-on when we do this.  Clicking the “Manage” button in the tray at the bottom will launch a new browser tab and single-sign us into the New Relic monitoring portal associated with our account: When we do this a new browser tab will launch with the New Relic admin tool loaded within it: We can now see insights into how our app is performing – without having to have written a single line of monitoring code.  The New Relic service provides a ton of great built-in monitoring features allowing us to quickly see: Performance times (including browser rendering speed) for the overall site and individual pages.  You can optionally set alert thresholds to trigger if the speed does not meet a threshold you specify. Information about where in the world your customers are hitting the site from (and how performance varies by region) Details on the latency performance of external services your web apps are using (for example: SQL, Storage, Twitter, etc) Error information including call stack details for exceptions that have occurred at runtime SQL Server profiling information – including which queries executed against your database and what their performance was And a whole bunch more… The cool thing about New Relic is that you don’t need to write monitoring code within your application to get all of the above reports (plus a lot more).  The New Relic agent automatically enables the CLR profiler within applications and automatically captures the information necessary to identify these.  This makes it super easy to get started and immediately have a rich developer analytics view for your solutions with very little effort. If you haven’t tried New Relic out yet with Windows Azure I recommend you do so – I think you’ll find it helps you build even better cloud applications.  Following the above steps will help you get started and deliver you a really good application monitoring solution in only minutes. Service Bus: Support for partitioned queues and topics With today’s release, we are enabling support within Service Bus for partitioned queues and topics. Enabling partitioning enables you to achieve a higher message throughput and better availability from your queues and topics. Higher message throughput is achieved by implementing multiple message brokers for each partitioned queue and topic.  The  multiple messaging stores will also provide higher availability. You can create a partitioned queue or topic by simply checking the Enable Partitioning option in the custom create wizard for a Queue or Topic: Read this article to learn more about partitioned queues and topics and how to take advantage of them today. Billing: New Billing Alert Service Today’s Windows Azure update enables a new Billing Alert Service Preview that enables you to get proactive email notifications when your Windows Azure bill goes above a certain monetary threshold that you configure.  This makes it easier to manage your bill and avoid potential surprises at the end of the month. With the Billing Alert Service Preview, you can now create email alerts to monitor and manage your monetary credits or your current bill total.  To set up an alert first sign-up for the free Billing Alert Service Preview.  Then visit the account management page, click on a subscription you have setup, and then navigate to the new Alerts tab that is available: The alerts tab allows you to setup email alerts that will be sent automatically once a certain threshold is hit.  For example, by clicking the “add alert” button above I can setup a rule to send myself email anytime my Windows Azure bill goes above $100 for the month: The Billing Alert Service will evolve to support additional aspects of your bill as well as support multiple forms of alerts such as SMS.  Try out the new Billing Alert Service Preview today and give us feedback. Summary Today’s Windows Azure release enables a ton of great new scenarios, and makes building applications hosted in the cloud even easier. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. 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

  • Snow Leopard takes a long time to connect to Windows/Samba server

    - by hood
    We run a very heterogeneous network here: There is some XP, Vista, 7, Leopard, Snow Leopard clients, and Windows 2003 (one remaining legacy app), 2008, and Linux servers. The main file server runs Ubuntu Linux and has been added to the Windows Domain and has been used for many years; SBS 2008 is the PDC (the 2003 and 2008 are on the domain also). In Leopard there were no problems at all authenticating to the file servers. We've upgraded one of the Leopard iMacs to Snow Leopard, though the same problem occurs in a new MBP which came with the newer OS as well as a clean install on another iMac. It does not matter whether connected through wired or wireless. In the Finder when clicking on the server - whether on first boot or after it is connected - it will display "Connecting..." for up to a few minutes before either generally working (if username/password in keychain) or displaying "Connection Failed" - at which time clicking "Connect As" and typing in the username/password will take some more time and eventually work. Sometimes it will display "Connecting..." indefinitely. (I've left it as long as 15 minutes before trying something else) Accessing shares on the the 2003 and SBS servers have the problem (so I don't think it's a Samba server issue). The Server 2008 Standard is connecting instantly at the moment. Accessing the share through an alias/stacks doesn't have this problem. Leopard and Windows clients still have no problem. I've searched Google but hasn't yielded any working result. How do I get rid of this delay?

  • postfix takes 60-90ms to queue email -- normal?

    - by Jeff Atwood
    We're seeing some (maybe?) strange delays when submitting individual emails to our local Postfix server. To help diagnose the issue, I wrote a little test program which sends 5 emails: get smtp 1ms ( 1 ms) email 0 677ms (676 ms) email 1 802ms (125 ms) email 2 890ms ( 88 ms) email 3 973ms ( 83 ms) email 4 1088ms (115 ms) Discounting the handshaking in the first email, that's about 90ms per email. These timings have also been corroborated with another test app written by someone else using a different codepath, so it appears to be server related. I turned on detailed logging and I can see that the delay is between the end of message \r\n\r\n and the receive: [16:31:29.95] [SEND] \r\n.\r\n [16:31:30.05] [RECV] 250 2.0.0 Ok: queued as B128E1E063\r\n [16:31:30.08] [SEND] \r\n.\r\n [16:31:30.17] [RECV] 250 2.0.0 Ok: queued as 4A7DE1E06E\r\n [16:31:30.19] [SEND] \r\n.\r\n [16:31:30.27] [RECV] 250 2.0.0 Ok: queued as 68ACC1E072\r\n [16:31:30.28] [SEND] \r\n.\r\n [16:31:30.34] [RECV] 250 2.0.0 Ok: queued as 7EFFE1E079\r\n [16:31:30.39] [SEND] \r\n.\r\n [16:31:30.45] [RECV] 250 2.0.0 Ok: queued as 9793C1E07A\r\n The time intervals tell the story (discounting the handshaking required for the initial email) -- each email is waiting about 60-90 milliseconds for postfix to queue! This seems .. excessive .. to me. Is it "normal" for postfix to take 60-90 ms for every email you send it? Or do I just have unreasonable expectations? I would expect the local postfix server to queue the email in about 20ms, tops!

  • MS hotfix delayed delivery.

    - by MOE37x3
    I just requested a hotfix from support.microsoft.com and put in my email address, but I haven't received the email yet. The splash page I got after I requested the hotfix said: Hotfix Confirmation We will send these hotfixes to the following e-mail address: (my correct email address) Usually, our hotfix e-mail is delivered to you within five minutes. However, sometimes unforeseen issues in e-mail delivery systems may cause delays. We will send the e-mail from the “[email protected]” e-mail account. If you use an e-mail filter or a SPAM blocker, we recommend that you add “[email protected]” or the “microsoft.com” domain to your safe senders list. (The safe senders list is also known as a whitelist or an approved senders list.) This will help prevent our e-mail from going into your junk e-mail folder or being automatically deleted. I'm sure that the email is not getting caught in a spam catcher. How long does it normally take to get one of these hotfixes? Am I waiting for some human to approve it, or something? Should I just give up and try to get the file I need some other way? (Update: Replaced "[email protected]" with "(my correct email address)" to resolve Martín Marconcini's ambiguity.)

  • Emails from Google Apps to custom SMTP server delayed by 1 hour consistently

    - by vimalk
    The outgoing mails from Google Apps/Gmail to our own custom SMTP server are getting delayed by 1 hour consistently. mxtoolbox.com diagnostics of our custom SMTP server are looking OK. Our custom SMTP server is receiving emails from other sources (yahoo, hotmail etc.) on time. Looking at the SMTP logs show a delay in a google intermediate SMTP server. Received: by qwi2 with SMTP id 2so1989393qwi.3 for <[email protected]>; Thu, 27 Jan 2011 03:54:23 -0800 (PST) MIME-Version: 1.0 Received: by 10.224.19.203 with SMTP id c11mr1587082qab.170.1296125657457; Thu, 27 Jan 2011 02:54:17 -0800 (PST) This setup has been working fine for a year though our custom email server was missing a reverse DNS entry and SPF records.

  • Jetty startup delay

    - by Tauren
    I'm trying to figure out what would be causing a 1 minute delay in the startup of Jetty. Is it a configuration problem, my application, or something else? I have Jetty 7 (jetty-7.0.1.v20091125 25 November 2009) installed on a server and I deploy a 45MB ROOT.war file into the webapps directory. This is the only webapp configured in Jetty. I then start Jetty with the command: java -DSTOP.PORT=8079 -DSTOP.KEY=mystopkey -Denv=stage -jar start.jar etc/jetty-logging.xml etc/jetty.xml & I get two lines of output right after doing this: 2010-03-07 14:20:06.642:INFO::Logging to StdErrLog::DEBUG=false via org.eclipse.jetty.util.log.StdErrLog 2010-03-07 14:20:06.710:INFO::Redirecting stderr/stdout to /home/zing/jetty-distribution-7.0.1.v20091125/logs/2010_03_07.stderrout.log When I press the enter key, I get my command prompt back. Looking at the log file (logs/2010_03_07.stderrout.log), I see the following at the beginning: 2010-03-07 14:08:50.396:INFO::jetty-7.0.1.v20091125 2010-03-07 14:08:50.495:INFO::Extract jar:file:/home/zing/jetty-distribution-7.0.1.v20091125/webapps/ROOT.war!/ to /tmp/Jetty_0_0_0_0_8080_ROOT.war___.8te0nm/webapp 2010-03-07 14:08:52.599:INFO::NO JSP Support for , did not find org.apache.jasper.servlet.JspServlet 2010-03-07 14:09:51.379:INFO::Set web app root system property: 'webapp.root' = [/tmp/Jetty_0_0_0_0_8080_ROOT.war___.8te0nm/webapp] 2010-03-07 14:09:51.585:INFO::Initializing Spring root WebApplicationContext INFO - ContextLoader - Root WebApplicationContext: initialization started INFO - XmlWebApplicationContext - Refreshing Root WebApplicationContext: startup date [Sun Mar 07 14:09:51 PST 2010]; root of context hierarchy ... Notice the 1 minute long pause between the 3rd and 4th lines. What is Jetty doing at this point? What other things could be going on? It doesn't even look like it has started my Spring initialization yet. Note that I checked my /tmp directory to see if it was simply the time to unpack my war file, but the file had been completely unpacked even at the start of this 1 minute delay.

  • jquery delay a link from being followed

    - by Dan Sinker
    I have a short css-based animation that I want to play out before a link is followed (a card that swooped in on page load swoops out after click). Currently, however, the page called loads too quickly. I want to be able to briefly delay the href from being followed. Here's what I've got: $(document).ready(function() { $("#card").css("top","0px"); $(".clickit").click(function() { $("#card").css("top","-500"); }); }); The first line swoops the card in on page load. After that is the click call that modifies the CSS, but like I said there needs to be some kind of delay in there because the page loads immediately, instead of after the animation. The CSS that is modified looks like this: #card { width: 400px; height: 500px; position: relative; top: -500px; -webkit-transition:all .5s; } (yes, I know this is webkit-only right now) This is a problem very similar to this question from 2008, but I know jQuery has been updated significantly since then, so I wanted to see if there was a more modern solution. Thank you!

  • Scheduling a Delay Job on Heroku with a Worker Dyno

    - by user1524775
    I'm currently using Heroku's scheduler to run a script. However, the time that the script takes to run is going to increase from a few milliseconds to a few minutes. I'm looking at using the delayed_job gem to push this process off to a Worker Dyno. I want to continue to run this script once-a-day, just offload it to the worker. My current rake task is: desc "This task updates some stuff for you." task :update_some_stuff => :environment do puts "Updating some stuff ..." SomeClass.new.process puts "... done." end Once the gem is installed, migration run, and worker dyno started, will the script just need to change to: desc "This task updates some stuff for you." task :update_some_stuff => :environment do puts "Updating some stuff ..." SomeClass.new.delay.process puts "... done." end With this task still being a rake task scheduled by Heroku's Scheduler, is the only thing that needs to happen here the introduction of the delay method to put this in the Worker's queue? Thanks in advance for any help.
