• Running Jetty under Windows Azure Using RoleEntryPoint in a Worker Role

  - by Shawn Cicoria

  This post is built upon the work of Mario Kosmiskas and David C. Chou’s prior postings – from here: http://blogs.msdn.com/b/mariok/archive/2011/01/05/deploying-java-applications-in-azure.aspx  http://blogs.msdn.com/b/dachou/archive/2010/03/21/run-java-with-jetty-in-windows-azure.aspx As Mario points out in his post, when you need to have more control over the process that starts, it generally is better left to a RoleEntryPoint capability that as of now, requires the use of a CLR based assembly that is deployed as part of the package to Azure. There were things I liked especially about Mario’s post – specifically, the ability to pull down the JRE and Jetty runtimes at role startup and instantiate the process using the extracted bits.  The way Mario initialized the java process (and Jetty) was to take advantage of a role startup task configured as part of the service definition.  This is a great quick way to kick off processes or tasks prior to your role entry point.  However, if you need access to service configuration values or role events, that’s where RoleEntryPoint comes in.  For this PoC sample I moved the logic for retrieving the bits for the jre and jetty to the worker roles OnStart – in addition to moving the process kickoff to the OnStart method.  The Run method at this point is there to loop and just report the status of the java process. Beyond just making things more parameterized, both Mario’s and David’s articles still form the essence of the approach. The solution that accompanies this post provides all the necessary .NET based Visual Studio project.  In addition, you’ll need: 1. Jetty 7 runtime http://www.eclipse.org/jetty/downloads.php 2. JRE http://www.oracle.com/technetwork/java/javase/downloads/index.html Once you have these the first step is to create archives (zips) of the distributions.  For this PoC, the structure of the archive requires that the root of the archive looks as follows: JRE6.zip jetty---.zip Upload the contents to a storage container (block blob), and for this example I used /archives as the location.  The service configuration has several settings that allow, which is the advantage of using RoleEntryPoint, the ability to provide these things via native configuration support from Azure in a worker role. Storage Explorer You can use development storage for testing this out – the zipped version of the solution is configured for development storage.  When you’re ready to deploy, you update the two settings – 1 for diagnostics and the other for the storage container where the /archives are going to be stored. <?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="HostedJetty" osFamily="2" osVersion="*"> <Role name="JettyWorker"> <Instances count="1" /> <ConfigurationSettings> <!--<Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="DefaultEndpointsProtocol=https;AccountName=<accountName>;AccountKey=<accountKey>" />--> <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" /> <Setting name="JettyArchive" value="jetty-distribution-7.3.0.v20110203b.zip" /> <Setting name="StartRole" value="true" /> <Setting name="BlobContainer" value="archives" /> <Setting name="JreArchive" value="jre6.zip" /> <!--<Setting name="StorageCredentials" value="DefaultEndpointsProtocol=https;AccountName=<accountName>;AccountKey=<accountKey>"/>--> <Setting name="StorageCredentials" value="UseDevelopmentStorage=true" />   For interacting with Storage you can use several tools – one tool that I like is from the Windows Azure CAT team located here: http://appfabriccat.com/2011/02/exploring-windows-azure-storage-apis-by-building-a-storage-explorer-application/  and shown in the prior picture At runtime, during role initialization and startup, Azure will call into your RoleEntryPoint.  At that time the code will do a dynamic pull of the 2 archives and extract – using the Sharp Zip Lib <link> as Mario had demonstrated in his sample.  The only different here is the use of CLR code vs. PowerShell (which is really CLR, but that’s another discussion). At this point, once the 2 zips are extracted, the Role’s file system looks as follows: Worker Role approot From there, the OnStart method (which also does the download and unzip using a simple StorageHelper class) kicks off the Java path and now you have Java! Task Manager Jetty Sample Page A couple of things I’m working on to enhance this is to extract the jre and jetty bits not to the appRoot but to a resource location defined as part of the service definition. ServiceDefinition.csdef <?xml version="1.0" encoding="utf-8"?> <ServiceDefinition name="HostedJetty" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition"> <WorkerRole name="JettyWorker"> <Imports> <Import moduleName="Diagnostics" /> <Import moduleName="RemoteAccess" /> <Import moduleName="RemoteForwarder" /> </Imports> <Endpoints> <InputEndpoint name="JettyPort" protocol="tcp" port="80" localPort="8080" /> </Endpoints> <LocalResources> <LocalStorage name="Archives" cleanOnRoleRecycle="false" sizeInMB="100" /> </LocalResources>   As the concept matures a bit, being able to update dynamically the content or jar files as part of a running java solution is something that is possible through continued enhancement of this simple model. The Visual Studio 2010 Solution is located here: HostingJavaSln_NDA.zip

• Simple-Talk development: a quick history lesson

  - by Michael Williamson

  Up until a few months ago, Simple-Talk ran on a pure .NET stack, with IIS as the web server and SQL Server as the database. Unfortunately, the platform for the site hadn’t quite gotten the love and attention it deserved. On the one hand, in the words of our esteemed editor Tony “I’d consider the current platform to be a “success”; it cost $10K, has lasted for 6 years, was finished, end to end in 6 months, and although we moan about it has got us quite a long way.” On the other hand, it was becoming increasingly clear that it needed some serious work. Among other issues, we had authors that wouldn’t blog because our current blogging platform, Community Server, was too painful for them to use. Forgetting about Simple-Talk for a moment, if you ask somebody what blogging platform they’d choose, the odds are they’d say WordPress. Regardless of its technical merits, it’s probably the most popular blogging platform, and it certainly seemed easier to use than Community Server. The issue was that WordPress is normally hosted on a Linux stack running PHP, Apache and MySQL — quite a difference from our Microsoft technology stack. We certainly didn’t want to rewrite the entire site — we just wanted a better blogging platform, with the rest of the existing, legacy site left as is. At a very high level, Simple-Talk’s technical design was originally very straightforward: when your browser sends an HTTP request to Simple-Talk, IIS (the web server) takes the request, does some work, and sends back a response. In order to keep the legacy site running, except with WordPress running the blogs, a different design is called for. We now use nginx as a reverse-proxy, which can then delegate requests to the appropriate application: So, when your browser sends a request to Simple-Talk, nginx takes that request and checks which part of the site you’re trying to access. Most of the time, it just passes the request along to IIS, which can then respond in much the same way it always has. However, if your request is for the blogs, then nginx delegates the request to WordPress. Unfortunately, as simple as that diagram looks, it hides an awful lot of complexity. In particular, the legacy site running on IIS was made up of four .NET applications. I’ve already mentioned one of these applications, Community Server, which handled the old blogs as well as managing membership and the forums. We have a couple of other applications to manage both our newsletters and our articles, and our own custom application to do some of the rendering on the site, such as the front page and the articles. When I say that it was made up of four .NET applications, this might conjure up an image in your mind of how they fit together: You might imagine four .NET applications, each with their own database, communicating over well-defined APIs. Sadly, reality was a little disappointing: We had four .NET applications that all ran on the same database. Worse still, there were many queries that happily joined across tables from multiple applications, meaning that each application was heavily dependent on the exact data schema that each other application used. Add to this that many of the queries were at least dozens of lines long, and practically identical to other queries except in a few key spots, and we can see that attempting to replace one component of the system would be more than a little tricky. However, the problems with the old system do give us a good place to start thinking about desirable qualities from any changes to the platform. Specifically: Maintainability — the tight coupling between each .NET application made it difficult to update any one application without also having to make changes elsewhere Replaceability — the tight coupling also meant that replacing one component wouldn’t be straightforward, especially if it wasn’t on a similar Microsoft stack. We’d like to be able to replace different parts without having to modify the existing codebase extensively Reusability — we’d like to be able to combine the different pieces of the system in different ways for different sites Repeatable deployments — rather than having to deploy the site manually with a long list of instructions, we should be able to deploy the entire site with a single command, allowing you to create a new instance of the site easily whether on production, staging servers, test servers or your own local machine Testability — if we can deploy the site with a single command, and each part of the site is no longer dependent on the specifics of how every other part of the site works, we can begin to run automated tests against the site, and against individual parts, both to prevent regressions and to do a little test-driven development In the next part, I’ll describe the high-level architecture we now have that hopefully brings us a little closer to these five traits.

• Responsible BI for Excel, Even for Older Versions

  - by andrewbrust

  On Wednesday, I will have the honor of co-presenting, for both The Data Warehouse Institute (TDWI) and the New York Technology Council. on the subject of Excel and BI. My co-presenter will be none other than Bill Baker, who was a Microsoft Distinguished Engineer and, essentially, the father of BI at that company.  Details on the events are here and here. We'll be talking about PowerPivot, of course, but that's not all. Probably even more important than any one product, will be our discussion of whether the usual characterization of Excel as the nemesis of IT, the guilty pleasure of business users and the antithesis of formal BI is really valid and/or hopelessly intractable. Without giving away our punchline, I'll tell you that we are much more optimistic than that. There are huge upsides to Excel and while there are real dangers to using it in the BI space, there are standards and practices you can employ to ensure Excel is used responsibly. And when those practices are followed, Excel becomes quite powerful indeed. One of the keys to this is using Excel as a data consumer rather than data storage mechanism. Caching data in Excel is OK, but only if that data is (a) not modified and (b) configured for automated periodic refresh. PowerPivot meets both criteria -- it stores a read-only copy of your data in the form of a model, and once workbook containing a PowerPivot model is published to SharePoint, it can be configured for scheduled data refresh, on the server, requiring no user intervention whatsoever. Data refresh is a bit like hard drive backup: it will only happen reliably if it's automated, and super-easy to configure. PowerPivot hits a real home run here (as does Windows Home Server for PC backup, but I digress). The thing about PowerPivot is that it's an add-in for Excel 2010. What if you're not planning to go to that new version for quite a while? What if you’ve just deployed Office 2007 in your organization? What if you're still on Office 2003, or an even earlier version? What can you do immediately to share data responsibly and easily? As it turns out, there's a feature in Excel that's been around for quite a while, that can help: Web Queries.  The Web Query feature was introduced, ostensibly, to allow Excel to pull data in from Internet Web pages…for example, data in a stock quote history table will come in nicely, as will any data in a Web page that is displayed in an HTML table.  To use the feature In Excel 2007 or 2010, click the Data Tab or the ribbon and click the “From Web” button towards the left; in older versions use the corresponding option in  the menu or  toolbars.  Next, paste a URL into the resulting dialog box and tap Enter or click the Go button.  A preview of the Web page will come up, and the dialog will allow you to select the specific table within the page whose data you’d like to import.  Here’s an example: Now just click the table, click the Import button, and the Import Data dialog appears.  You can simply click OK to bring in your data or you can first click the Properties… button and configure the data import to be refreshed at an interval in minutes that you select.  Now your data’s in the spreadsheet and ready to worked with: Your data may be vulnerable to modification, but if you’ve set up the data refresh, any accidental or malicious changes will be corrected in time anyway. The thing about this feature is that it’s most useful not for public Web pages, but for pages behind the firewall.  In effect, the Web Query feature provides an incredibly easy way to consume data in Excel that’s “published” from an application.  Users just need a URL.  They don’t need to know server and database names and since the data is read-only, providing credentials may be unnecessary, or can be handled using integrated security.  If that’s not good enough, the Web Query can be saved to a special .iqy file, which can be edited to provide POST parameter data. The only requirement is that the data must be provided in an HTML table, with the first row providing the column names.  From an ASP.NET project, it couldn’t be easier: a simple bound GridView control is totally compatible.  Use a data source control with it, and you don’t even have to write any code.  Users can link to pages that are part of an application’s UI, or developers can create pages that are specially designed for the purpose of providing an interface to the Web Query import feature.  And none of this is Microsoft- or .NET-specific.  You can create pages in any language you want (PHP comes to mind) that output the result set of a query in HTML table format, and then consume that data in a Web Query.  Then build PivotTables and charts on the data, and in Excel 2007 or 2010 you can use conditional formatting to create scorecards and dashboards. This strategy allows you to create pages that function quite similarly to the OData XML feeds rendered when .NET developers create an “Astoria” WCF Data Service.  And while it’s cool that PowerPivot and Excel 2010 can import such OData feeds, it’s good to know that older versions of Excel can function in a similar fashion, and can consume data produced by virtually any Web development platform. As a final matter, instead of just telling you that “older versions” of Excel support this feature, I’ll be more specific.  To discover what the first version of Excel was to support Web queries, go to http://bit.ly/OldSchoolXL.

• Announcing the New Windows Azure Web Sites Shared Scaling Tier

  - by Clint Edmonson

  Windows Azure Web Sites has added a new pricing tier that will solve the #1 blocker for the web development community. The shared tier now supports custom domain names mapped to shared-instance web sites. This post will outline the plan changes and elaborate on how the new pricing model makes Windows Azure Web Sites an even richer option for web development shops of all sizes. Free Shared Reserved # of Sites 10 100 100 Egress 165MB/Day 5GB/Month Included 5GB/Month Included Storage 1GB 1GB 10GB Throttling CPU/Memory/Egress CPU/Memory Unlimited Price Free $.02/hr per site, per instance $.08/hr per core Setting the Stage In June, we released the first public preview of Windows Azure Web Sites, which gave web developers a great platform on which to get web sites running using their web development framework of choice. PHP, Node.js, classic ASP, and ASP.NET developers can all utilize the Windows Azure platform to create and launch their web sites. Likewise, these developers have a series of data storage options using Windows Azure SQL Databases, MySQL, or Windows Azure Storage. The Windows Azure Web Sites free offer enabled startups to get their site up and running on Windows Azure with a minimal investment, and with multiple deployment and continuous integration features such as Git, Team Foundation Services, FTP, and Web Deploy.  The response to the Windows Azure Web Sites offer has been overwhelmingly positive. Since the addition of the service on June 12th, tens of thousands of web sites have been deployed to Windows Azure and the volume of adoption is increasing every week. Preview Feedback In spite of the growth and success of the product, the community has had questions about features lacking in the free preview offer. The main question web developers asked regarding Windows Azure Web Sites relates to the lack of the free offer’s support for domain name mapping. During the preview launch period, customer feedback made it obvious that the lack of domain name mapping support was an area of concern. We’re happy to announce that this #1 request has been delivered as a feature of the new shared plan. New Shared Tier Portal Features In the screen shot below, the “Scale” tab in the portal shows the new tiers – Free, Shared, and Reserved – and gives the user the ability to quickly move any of their free web sites into the shared tier. With a single mouse-click, the user can move their site into the shared tier. Once a site has been moved into the shared tier, a new Manage Domains button appears in the bottom action bar of the Windows Azure Portal giving site owners the ability to manage their domain names for a shared site. This button brings up the domain-management dialog, which can be used to enter in a specific domain name that will be mapped to the Windows Azure Web Site. Shared Tier Benefits Startups and large web agencies will both benefit from this plan change. Here are a few examples of scenarios which fit the new pricing model: Startups no longer have to select the reserved plan to map domain names to their sites. Instead, they can use the free option to develop their sites and choose on a site-by-site basis which sites they elect to move into the shared plan, paying only for the sites that are finished and ready to be domain-mapped Agencies who manage dozens of sites will realize a lower cost of ownership over the long term by moving their sites into reserved mode. Once multi-site companies reach a certain price point in the shared tier, it is much more cost-effective to move sites to a reserved tier.  Long-term, it’s easy to see how the new Windows Azure Web Sites shared pricing tier makes Windows Azure Web Sites it a great choice for both startups and agency customers, as it enables rapid growth and upgrades while keeping the cost to a minimum. Large agencies will be able to have all of their sites in their own instances, and startups will have the capability to scale up to multiple-shared instances for minimal cost and eventually move to reserved instances without worrying about the need to incur continually additional costs. Customers can feel confident they have the power of the Microsoft Windows Azure brand and our world-class support, at prices competitive in the market. Plus, in addition to realizing the cost savings, they’ll have the whole family of Windows Azure features available. Continuous Deployment from GitHub and CodePlex Along with this new announcement are two other exciting new features. I’m proud to announce that web developers can now publish their web sites directly from CodePlex or GitHub.com repositories. Once connections are established between these services and your web sites, Windows Azure will automatically be notified every time a check-in occurs. This will then trigger Windows Azure to pull the source and compile/deploy the new version of your app to your web site automatically. Walk-through videos on how to perform these functions are below: Publishing to an Azure Web Site from CodePlex Publishing to an Azure Web Site from GitHub.com These changes, as well as the enhancements to the reserved plan model, make Windows Azure Web Sites a truly competitive hosting option. It’s never been easier or cheaper for a web developer to get up and running. Check out the free Windows Azure web site offering and see for yourself.

• OS Analytics with Oracle Enterprise Manager (by Eran Steiner)

  - by Zeynep Koch

  Oracle Enterprise Manager Ops Center provides a feature called "OS Analytics". This feature allows you to get a better understanding of how the Operating System is being utilized. You can research the historical usage as well as real time data. This post will show how you can benefit from OS Analytics and how it works behind the scenes. The recording of our call to discuss this blog is available here: https://oracleconferencing.webex.com/oracleconferencing/ldr.php?AT=pb&SP=MC&rID=71517797&rKey=4ec9d4a3508564b3Download the presentation here See also: Blog about Alert Monitoring and Problem Notification Blog about Using Operational Profiles to Install Packages and other content Here is quick summary of what you can do with OS Analytics in Ops Center: View historical charts and real time value of CPU, memory, network and disk utilization Find the top CPU and Memory processes in real time or at a certain historical day Determine proper monitoring thresholds based on historical data Drill down into a process details Where to start To start with OS Analytics, choose the OS asset in the tree and click the Analytics tab. You can see the CPU utilization, Memory utilization and Network utilization, along with the current real time top 5 processes in each category (click the image to see a larger version):  In the above screen, you can click each of the top 5 processes to see a more detailed view of that process. Here is an example of one of the processes: One of the cool things is that you can see the process tree for this process along with some port binding and open file descriptors. Next, click the "Processes" tab to see real time information of all the processes on the machine: An interesting column is the "Target" column. If you configured Ops Center to work with Enterprise Manager Cloud Control, then the two products will talk to each other and Ops Center will display the correlated target from Cloud Control in this table. If you are only using Ops Center - this column will remain empty. The "Threshold" tab is particularly helpful - you can view historical trends of different monitored values and based on the graph - determine what the monitoring values should be: You can ask Ops Center to suggest monitoring levels based on the historical values or you can set your own. The different colors in the graph represent the current set levels: Red for critical, Yellow for warning and Blue for Information, allowing you to quickly see how they're positioned against real data. It's important to note that when looking at longer periods, Ops Center smooths out the data and uses averages. So when looking at values such as CPU Usage, try shorter time frames which are more detailed, such as one hour or one day. Applying new monitoring values When first applying new values to monitored attributes - a popup will come up asking if it's OK to get you out of the current Monitoring Policy. This is OK if you want to either have custom monitoring for a specific machine, or if you want to use this current machine as a "Gold image" and extract a Monitoring Policy from it. You can later apply the new Monitoring Policy to other machines and also set it as a default Monitoring Profile. Once you're done with applying the different monitoring values, you can review and change them in the "Monitoring" tab. You can also click the "Extract a Monitoring Policy" in the actions pane on the right to save all the new values to a new Monitoring Policy, which can then be found under "Plan Management" -> "Monitoring Policies". Visiting the past Under the "History" tab you can "go back in time". This is very helpful when you know that a machine was busy a few hours ago (perhaps in the middle of the night?), but you were not around to take a look at it in real time. Here's a view into yesterday's data on one of the machines: You can see an interesting CPU spike happening at around 3:30 am along with some memory use. In the bottom table you can see the top 5 CPU and Memory consumers at the requested time. Very quickly you can see that this spike is related to the Solaris 11 IPS repository synchronization process using the "pkgrecv" command. The "time machine" doesn't stop here - you can also view historical data to determine which of the zones was the busiest at a given time: Under the hood The data collected is stored on each of the agents under /var/opt/sun/xvm/analytics/historical/ An "os.zip" file exists for the main OS. Inside you will find many small text files, named after the Epoch time stamp in which they were taken If you have any zones, there will be a file called "guests.zip" containing the same small files for all the zones, as well as a folder with the name of the zone along with "os.zip" in it If this is the Enterprise Controller or the Proxy Controller, you will have folders called "proxy" and "sat" in which you will find the "os.zip" for that controller The actual script collecting the data can be viewed for debugging purposes as well: On Linux, the location is: /opt/sun/xvmoc/private/os_analytics/collect If you would like to redirect all the standard error into a file for debugging, touch the following file and the output will go into it: # touch /tmp/.collect.stderr   The temporary data is collected under /var/opt/sun/xvm/analytics/.collectdb until it is zipped. If you would like to review the properties for the Analytics, you can view those per each agent in /opt/sun/n1gc/lib/XVM.properties. Find the section "Analytics configurable properties for OS and VSC" to view the Analytics specific values. I hope you find this helpful! Please post questions in the comments below. Eran Steiner

• Windows Azure Recipe: Enterprise LOBs

  - by Clint Edmonson

  Enterprises are more and more dependent on their specialized internal Line of Business (LOB) applications than ever before. Naturally, the more software they leverage on-premises, the more infrastructure they need manage. It’s frequently the case that our customers simply can’t scale up their hardware purchases and operational staff as fast as internal demand for software requires. The result is that getting new or enhanced applications in the hands of business users becomes slower and more expensive every day. Being able to quickly deliver applications in a rapidly changing business environment while maintaining high standards of corporate security is a challenge that can be met right now by moving enterprise LOBs out into the cloud and leveraging Azure’s Access Control services. In fact, we’re seeing many of our customers (both large and small) see huge benefits from moving their web based business applications such as corporate help desks, expense tracking, travel portals, timesheets, and more to Windows Azure. Drivers Cost Reduction Time to market Security Solution Here’s a sketch of how many Windows Azure Enterprise LOBs are being architected and deployed: Ingredients Web Role – this will host the core of the application. Each web role is a virtual machine hosting an application written in ASP.NET (or optionally php, or node.js). The number of web roles can be scaled up or down as needed to handle peak and non-peak traffic loads. Many Java based applications are also being deployed to Windows Azure with a little more effort. Database – every modern web application needs to store data. SQL Azure databases look and act exactly like their on-premise siblings but are fault tolerant and have data redundancy built in. Access Control – this service is necessary to establish federated identity between the cloud hosted application and an enterprise’s corporate network. It works in conjunction with a secure token service (STS) that is hosted on-premises to establish the corporate user’s identity and credentials. The source code for an on-premises STS is provided in the Windows Azure training kit and merely needs to be customized for the corporate environment and published on a publicly accessible corporate web site. Once set up, corporate users see a near seamless single sign-on experience. Reporting – businesses live and die by their reports and SQL Azure Reporting, based on SQL Server Reporting 2008 R2, can serve up reports with tables, charts, maps, gauges, and more. These reports can be accessed from the Windows Azure Portal, through a web browser, or directly from applications. Service Bus (optional) – if deep integration with other applications and systems is needed, the service bus is the answer. It enables secure service layer communication between applications hosted behind firewalls in on-premises or partner datacenters and applications hosted inside Windows Azure. The Service Bus provides the ability to securely expose just the information and services that are necessary to create a simpler, more secure architecture than opening up a full blown VPN. Data Sync (optional) – in cases where the data stored in the cloud needs to be shared internally, establishing a secure one-way or two-way data-sync connection between the on-premises and off-premises databases is a perfect option. It can be very granular, allowing us to specify exactly what tables and columns to synchronize, setup filters to sync only a subset of rows, set the conflict resolution policy for two-way sync, and specify how frequently data should be synchronized Training Labs These links point to online Windows Azure training labs where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure (16 labs) Windows Azure is an internet-scale cloud computing and services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services which can be used individually or together. It gives developers the choice to build web applications; applications running on connected devices, PCs, or servers; or hybrid solutions offering the best of both worlds. New or enhanced applications can be built using existing skills with the Visual Studio development environment and the .NET Framework. With its standards-based and interoperable approach, the services platform supports multiple internet protocols, including HTTP, REST, SOAP, and plain XML SQL Azure (7 labs) Microsoft SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. Windows Azure Services (9 labs) As applications collaborate across organizational boundaries, ensuring secure transactions across disparate security domains is crucial but difficult to implement. Windows Azure Services provides hosted authentication and access control using powerful, secure, standards-based infrastructure. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

• OpenGL (glx) not working with ubuntu 12.10

  - by user26766

  It all started when I installed nvidia's own (download from website) driver. Uninstalling it and reverting back to nvidia-current didn't solve the problem, so I have been playing with this for a while. It seems glx support is missing, and my intel graphics is not responding. gnome loads only in fallback mode. Here are some outputs: glxinfo name of display: :0.0 Error: couldn't find RGB GLX visual or fbconfig glxgears Error: couldn't get an RGB, Double-buffered visual optirun glxgears works fine lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev ff) Here's the content of log file when just after running glxinfo: less /var/log/Xorg.0.log | grep gl [ 112.156] (II) LoadModule: "glx" [ 112.157] (II) Loading /usr/lib/xorg/modules/extensions/libglx.so [ 112.157] (II) Module glx: vendor="X.Org Foundation" [ 112.157] (II) UnloadModule: "glx" [ 112.157] (II) Unloading glx [ 112.157] (EE) Failed to load module "glx" (module requirement mismatch, 0) Some more info... lsmod Module Size Used by bbswitch 13612 0 pci_stub 12623 1 vboxpci 23195 0 vboxnetadp 25671 0 vboxnetflt 23480 0 vboxdrv 320372 3 vboxpci,vboxnetadp,vboxnetflt parport_pc 32689 0 ppdev 17074 0 bnep 18141 2 rfcomm 46620 12 binfmt_misc 17501 1 snd_hda_codec_hdmi 32049 1 snd_hda_codec_realtek 78147 1 joydev 17458 0 uvcvideo 76750 0 videobuf2_core 32852 1 uvcvideo videodev 120310 2 uvcvideo,videobuf2_core videobuf2_vmalloc 12861 1 uvcvideo videobuf2_memops 13405 1 videobuf2_vmalloc snd_hda_intel 33492 3 coretemp 13401 0 kvm_intel 132760 0 arc4 12530 2 snd_hda_codec 134213 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel kvm 414111 1 kvm_intel iwlwifi 386837 0 i915 520799 2 snd_hwdep 17699 1 snd_hda_codec snd_pcm 96668 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec psmouse 100389 0 drm_kms_helper 49113 1 i915 ghash_clmulni_intel 13221 0 snd_seq_midi 13325 0 snd_rawmidi 30513 1 snd_seq_midi btusb 22475 0 drm 288436 3 i915,drm_kms_helper serio_raw 13216 0 snd_seq_midi_event 14900 1 snd_seq_midi snd_seq 61555 2 snd_seq_midi,snd_seq_midi_event mac80211 535936 1 iwlwifi bluetooth 209249 22 bnep,rfcomm,btusb snd_timer 29426 2 snd_pcm,snd_seq snd_seq_device 14498 3 snd_seq_midi,snd_rawmidi,snd_seq snd 78921 16 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device cfg80211 206797 2 iwlwifi,mac80211 aesni_intel 51038 1 cryptd 20404 2 ghash_clmulni_intel,aesni_intel aes_x86_64 17256 1 aesni_intel dell_wmi 12682 0 sparse_keymap 13891 1 dell_wmi dcdbas 14439 0 i2c_algo_bit 13414 1 i915 microcode 22804 0 lpc_ich 17062 0 soundcore 15048 1 snd snd_page_alloc 18485 2 snd_hda_intel,snd_pcm video 19391 1 i915 mac_hid 13206 0 wmi 19071 1 dell_wmi mei 40691 0 lp 17760 0 parport 46346 3 parport_pc,ppdev,lp ahci 25721 3 libahci 31192 1 ahci atl1c 41102 0 how can I fix this? any ideas?

However I didn't find any obvious link to /lib/nvidia-current in /etc/ld.so.conf (where the directories containing the shared libraries are listed). I don't know if there's anything missing or if this is normal. thanks, UPDATE: The problem was solved by updating to Ubuntu 13.04. It seems bumblebee was to blame, but I'm not sure what was going wrong...

• Career guidance/advice for Junior-level Software Engineer [closed]

  - by John Do

  I have quite a few questions on my mind, so please bare with me. Please don't feel obligated to answer all of them, any as you choose will do. I'd appreciate if you could share some insight on any of these. Before I begin, some context: I currently have almost two years of professional experience as a Software Engineer, mainly developing software in Java. At this point, I feel that I have reached the peak in my career growth at the current company I am at and therefore I am looking for a new job, ideally again, as a Software Engineer. I have been interviewing for the past few months casually but have not had luck with companies I have a passion for. So, in no particular order - 1) In general, what are your thoughts on having graduate degrees in CS / Software Engineering. How much does it influence a salary increase, and do you think it's beneficial when working on real-world problems? I get the sense that a graduate degree in the field is trivial unless you really have a passion for research. 2) In general, in professional practice, how often had you have to write your own data structures and "complex" algorithms from scratch? In my own work, I have found myself relying mainly on third-party frameworks and the Java standard library to implement solutions as per business requirements. What are your thoughts on this? 3) In terms of resume, I feel the most ambivalent here. I want to be able to "blemish" my resume to a certain extent so that it stands out from others', but at the same time I do not want to over-exagerate my abilities. How do you strike a balance here? For example: I say that I am proficient in Java with data structures and algorithms. This is obviously a subjective and relative statement. I've taken the classes in my undergrad, and I've applied it in my work experience. What I feel as "prociency" can be seen as junior-level to others. How do you know what to say? Most of the time, recruiters (with no technical background) will be looking for keywords that stand out. This leads me to my next question (4). 4) Just from interviewing for the past few months (and getting plenty of rejections), I've come to realize that I may not be as proficient in data structures and algorithms as I thought I was. Do you think it's a good idea to remove the "proficient in java/data structure and algorithms"? I feel that being too hoenst on the resume will impede me from scoring opportunities to even have an interview with top-notch companies. What are your thoughts? 5) What is the absolute "must-have" knowledge going into a technical interview? I've been practicing several algorithmic and data sturcture problems now, and I feel that my abilities to solve arbitrary problems efficiently has not gotten significantly better. Do you think these abilities are something innate - it's either you have in you, or you don't? How can you teach yourself to learn, if you will? 6) How easy is it to go from industry/function to the next? I work mainly with backend technologies and I'm now interested in working with the frontend, i.e javascript,jquery,php or even mobile development. In your own experience, how did you not get pidgeon holed in your career? I feel that the choices you make now ultimately decide your future. As cliche as it sounds, I think it may be true. Here's what I mean: you've worked mainly as a backend engineer, people are interested in you doing the same thing since you've already accumulated experience in that function. How do get experience in a new function if people won't accept you because you don't already have it? It's a catch 22, you see... Are side projects the only real way to help you move from one function to another that you're truly interested in? For example: I could start writing my own mobile applications, even though I've worked mainly on the backend. Thanks so much for the long read. As a relatively new engineer to the real world, I am very humble and would like those who are experienced to shed some light. Thank you so much.

• Modularity through HTTP

  - by Michael Williamson

  As programmers, we strive for modularity in the code we write. We hope that splitting the problem up makes it easier to solve, and allows us to reuse parts of our code in other applications. Object-orientation is the most obvious of many attempts to get us closer to this ideal, and yet one of the most successful approaches is almost accidental: the web. Programming languages provide us with functions and classes, and plenty of other ways to modularize our code. This allows us to take our large problem, split it into small parts, and solve those small parts without having to worry about the whole. It also makes it easier to reason about our code. So far, so good, but now that we’ve written our small, independent module, for example to send out e-mails to my customers, we’d like to reuse it in another application. By creating DLLs, JARs or our platform’s package container of choice, we can do just that – provided our new application is on the same platform. Want to use a Java library from C#? Well, good luck – it might be possible, but it’s not going to be smooth sailing. Even if a library exists, it doesn’t mean that using it going to be a pleasant experience. Say I want to use Java to write out an XML document to an output stream. You’d imagine this would be a simple one-liner. You’d be wrong: import org.w3c.dom.*; import java.io.*; import javax.xml.transform.*; import javax.xml.transform.dom.*; import javax.xml.transform.stream.*; private static final void writeDoc(Document doc, OutputStream out) throws IOException { try { Transformer t = TransformerFactory.newInstance().newTransformer(); t.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, doc.getDoctype().getSystemId()); t.transform(new DOMSource(doc), new StreamResult(out)); } catch (TransformerException e) { throw new AssertionError(e); // Can't happen! } } Most of the time, there is a good chance somebody else has written the code before, but if nobody can understand the interface to that code, nobody’s going to use it. The result is that most of the code we write is just a variation on a theme. Despite our best efforts, we’ve fallen a little short of our ideal, but the web brings us closer. If we want to send e-mails to our customers, we could write an e-mail-sending library. More likely, we’d use an existing one for our language. Even then, we probably wouldn’t have niceties like A/B testing or DKIM signing. Alternatively, we could just fire some HTTP requests at MailChimp, and get a whole slew of features without getting anywhere near the code that implements them. The web is inherently language agnostic. So long as your language can send and receive text over HTTP, and probably parse some JSON, you’re about as well equipped as anybody. Instead of building libraries for a specific language, we can build a service that almost every language can reuse. The text-based nature of HTTP also helps to limit the complexity of the API. As SOAP will attest, you can still make a horrible mess using HTTP, but at least it is an obvious horrible mess. Complex data structures are tedious to marshal to and from text, providing a strong incentive to keep things simple. By contrast, spotting the complexities in a class hierarchy is often not as easy. HTTP doesn’t solve every problem. It probably isn’t such a good idea to use it inside an inner loop that’s executed thousands of times per second. What’s more, the HTTP approach might introduce some new problems. We often need to add a thin shim to each application that we wish to communicate over HTTP. For instance, we might need to write a small plugin in PHP if we want to integrate WordPress into our system. Suddenly, instead of a system written in one language, we’re maintaining a system with several distinct languages and platforms. Even then, we should strive to avoid re-implementing the same old thing. As programmers, we consistently underestimate both the cost of building a system and the ongoing maintenance. If we allow ourselves to integrate existing applications, even if they’re in unfamiliar languages, we save ourselves those development and maintenance costs, as well as being able to pick the best solution for our problem. Thanks to the web, HTTP is often the easiest way to get there.

• Building a plug-in for Windows Live Writer

  - by mbcrump

  This tutorial will show you how to build a plug-in for Windows Live Writer. Windows Live Writer is a blogging tool that Microsoft provides for free. It includes an open API for .NET developers to create custom plug-ins. In this tutorial, I will show you how easy it is to build one. Open VS2008 or VS2010 and create a new project. Set the target framework to 2.0, Application Type to Class Library and give it a name. In this tutorial, we are going to create a plug-in that generates a twitter message with your blog post name and a TinyUrl link to the blog post.  It will do all of this automatically after you publish your post. Once, we have a new projected created. We need to setup the references. Add a reference to the WindowsLive.Writer.Api.dll located in the C:\Program Files (x86)\Windows Live\Writer\ folder, if you are using X64 version of Windows. You will also need to add a reference to System.Windows.Forms System.Web from the .NET tab as well. Once that is complete, add your “using” statements so that it looks like whats shown below: Live Writer Plug-In "Using" using System; using System.Collections.Generic; using System.Text; using WindowsLive.Writer.Api; using System.Web; Now, we are going to setup some build events to make it easier to test our custom class. Go into the Properties of your project and select Build Events, click edit the Post-build and copy/paste the following line: XCOPY /D /Y /R "$(TargetPath)" "C:\Program Files (x86)\Windows Live\Writer\Plugins\" Your screen should look like the one pictured below: Next, we are going to launch an external program on debug. Click the debug tab and enter C:\Program Files (x86)\Windows Live\Writer\WindowsLiveWriter.exe Your screen should look like the one pictured below:   Now we have a blank project and we need to add some code. We start with adding the attributes for the Live Writer Plugin. Before we get started creating the Attributes, we need to create a GUID. This GUID will uniquely identity our plug-in. So, to create a GUID follow the steps in VS2008/2010. Click Tools from the VS Menu ->Create GUID It will generate a GUID like the one listed below: GUID <Guid("56ED8A2C-F216-420D-91A1-F7541495DBDA")> We only want what’s inside the quotes, so your final product should be: "56ED8A2C-F216-420D-91A1-F7541495DBDA". Go ahead and paste this snipped into your class just above the public class. Live Writer Plug-In Attributes [WriterPlugin("56ED8A2C-F216-420D-91A1-F7541495DBDA",    "Generate Twitter Message",    Description = "After your new post has been published, this plug-in will attempt to generate a Twitter status messsage with the Title and TinyUrl link.",    HasEditableOptions = false,    Name = "Generate Twitter Message",    PublisherUrl = "http://michaelcrump.net")] [InsertableContentSource("Generate Twitter Message")] So far, it should look like the following: Next, we need to implement the PublishNotifcationHook class and override the OnPostPublish. I’m not going to dive into what the code is doing as you should be able to follow pretty easily. The code below is the entire code used in the project. PublishNotificationHook public class Class1 :  PublishNotificationHook  {      public override void OnPostPublish(System.Windows.Forms.IWin32Window dialogOwner, IProperties properties, IPublishingContext publishingContext, bool publish)      {          if (!publish) return;          if (string.IsNullOrEmpty(publishingContext.PostInfo.Permalink))          {              PluginDiagnostics.LogError("Live Tweet didn't execute, due to blank permalink");          }          else          {                var strBlogName = HttpUtility.UrlEncode("#blogged : " + publishingContext.PostInfo.Title);  //Blog Post Title              var strUrlFinal = getTinyUrl(publishingContext.PostInfo.Permalink); //Blog Permalink URL Converted to TinyURL              System.Diagnostics.Process.Start("http://twitter.com/home?status=" + strBlogName + strUrlFinal);            }      } We are going to go ahead and create a method to create the short url (tinyurl). TinyURL Helper Method private static string getTinyUrl(string url) {     var cmpUrl = System.Globalization.CultureInfo.InvariantCulture.CompareInfo;     if (!cmpUrl.IsPrefix(url, "http://tinyurl.com"))     {         var address = "http://tinyurl.com/api-create.php?url=" + url;         var client = new System.Net.WebClient();         return (client.DownloadString(address));     }     return (url); } Go ahead and build your project, it should have copied the .DLL into the Windows Live Writer Plugin Directory. If it did not, then you will want to check your configuration. Once that is complete, open Windows Live Writer and select Tools-> Options-> Plug-ins and enable your plug-in that you just created. Your screen should look like the one pictured below: Go ahead and click OK and publish your blog post. You should get a pop-up with the following: Hit OK and It should open a Twitter and either ask for a login or fill in your status as shown below:   That should do it, you can do so many other things with the API. I suggest that if you want to build something really useful consult the MSDN pages. This plug-in that I created was perfect for what I needed and I hope someone finds it useful.

• SOA, Governance, and Drugs

  Why is IT governance important in service oriented architecture (SOA)? IT Governance provides a framework for making appropriate decisions based on company guidelines and accepted standards. This framework also outlines each stakeholder’s responsibilities and authority when making important architectural or design decisions. Furthermore, this framework of governance defines parameters and constraints that are used to give context and perspective when making decisions. The use of governance as it applies to SOA ensures that specific design principles and patterns are used when developing and maintaining services. When governance is consistently applied systems the following benefits are achieved according to Anne Thomas Manes in 2010. Governance makes sure that services conform to standard interface patterns, common data modeling practices, and promotes the incorporation of existing system functionality by building on top of other available services across a system. Governance defines development standards based on proven design principles and patterns that promote reuse and composition. Governance provides developers a set of proven design principles, standards and practices that promote the reduction in system based component dependencies.  By following these guidelines, individual components will be easier to maintain. For me personally, I am a fan of IT governance, and feel that it valuable part of any corporate IT department. However, depending on how it is implemented can really affect the value of using IT governance.  Companies need to find a way to ensure that governance does not become extreme in its policies and procedures. I know for me personally, I would really dislike working under a completely totalitarian or laissez-faire version of governance. Developers need to be able to be creative in their designs and too much governance can really impede the design process and prevent the most optimal design from being developed. On the other hand, with no governance enforced, no standards will be followed and accepted design patterns will be ignored. I have personally had to spend a lot of time working on this particular scenario and I have found that the concept of code reuse and composition is almost nonexistent.  Based on this, too much time and money is wasted on redeveloping existing aspects of an application that already exist within the system as a whole. I think moving forward we will see a staggered form of IT governance, regardless if it is for SOA or IT in general.  Depending on the size of a company and the size of its IT department,  I can see IT governance as a layered approach in that the top layer will be defined by enterprise architects that focus on abstract concepts pertaining to high level design, general  guidelines, acceptable best practices, and recommended design patterns.  The next layer will be defined by solution architects or department managers that further expand on abstracted guidelines defined by the enterprise architects. This layer will contain further definitions as to when various design patterns, coding standards, and best practices are to be applied based on the context of the solutions that are being developed by the department. The final layer will be defined by the system designer or a solutions architect assed to a project in that they will define what design patterns will be used in a solution, naming conventions, as well as outline how a system will function based on the best practices defined by the previous layers. This layered approach allows for IT departments to be flexible in that system designers have creative leeway in designing solutions to meet the needs of the business, but they must operate within the confines of the abstracted IT governance guidelines.  A real world example of this can be seen in the United States as it pertains to governance of the people in that the US government defines rules and regulations in the abstract and then the state governments take these guidelines and applies them based on the will of the people in each individual state. Furthermore, the county or city governments are the ones that actually enforce these rules based on how they are interpreted by local community.  To further define my example, the United States government defines that marijuana is illegal. Each individual state has the option to determine this regulation as it wishes in that the state of Florida determines that all uses of the drug are illegal, but the state of California legally allows the use of marijuana for medicinal purposes only. Based on these accepted practices each local government enforces these rules in that a police officer will arrest anyone in the state of Florida for having this drug on them if they walk down the street, but in California if a person has a medical prescription for the drug they will not get arrested.  REFERENCESThomas Manes, Anne.

• www.domain redirecting to google?

  - by aayush

  Note: A while back i had no place to host my domain, then via namecheap i set it to forward my domain to google I bought webhosting again today and everything was working fine. I set up vhosts and set up www.domain as the server alias. Both worked. Then i tried to set up a alternate subdomain test.domain, but failed (I did it by creating a alternate vhost right below the current one) as it kept redirecting to google. As a test, i replaced the www with test in serveralias, it still redirected to google but now even www redirects to google. I am using cloudflare, and i am really confused how to go about this. I tried listing www as a cname and as a A record, still redirecting to google. I tried checking via proxies e.t.c, its universal and hence not a problem of my PC. Please help, i am really distressed by this. I am running a ubuntu 13.10 x32 stack with LAMP. Here is what my domain.com.conf file looks like <VirtualHost *:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly. ServerName domain.com ServerAlias www.domain.com ServerAdmin webmaster@localhost DocumentRoot /var/www/domain.com/public_html # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the loglevel for particular # modules, e.g. #LogLevel info ssl:warn ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined # For most configuration files from conf-available/, which are # enabled or disabled at a global level, it is possible to # include a line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally disabled with "a2disconf". #Include conf-available/serve-cgi-bin.conf </VirtualHost> There is a valid index.php file at the end of the documentroot aswell. The website in question is aayushagra.com Edit: On cloudflare i tried removing the www entirely, and it still sent me to google Edit: Zone file ;; Domain: aayushagra.com ;; Exported: 2013-11-03 07:37:52 ;; ;; This file is intended for use for informational and archival ;; purposes ONLY and MUST be edited before use on a production ;; DNS server.

• Is there a Math.atan2 substitute for j2ME? Blackberry development

  - by Kai

  I have a wide variety of locations stored in my persistent object that contain latitudes and longitudes in double(43.7389, 7.42577) format. I need to be able to grab the user's latitude and longitude and select all items within, say 1 mile. Walking distance. I have done this in PHP so I snagged my PHP code and transferred it to Java, where everything plugged in fine until I figured out J2ME doesn't support atan2(double, double). So, after some searching, I find a small snippet of code that is supposed to be a substitute for atan2. Here is the code: public double atan2(double y, double x) { double coeff_1 = Math.PI / 4d; double coeff_2 = 3d * coeff_1; double abs_y = Math.abs(y)+ 1e-10f; double r, angle; if (x >= 0d) { r = (x - abs_y) / (x + abs_y); angle = coeff_1; } else { r = (x + abs_y) / (abs_y - x); angle = coeff_2; } angle += (0.1963f * r * r - 0.9817f) * r; return y < 0.0f ? -angle : angle; } I am getting odd results from this. My min and max latitude and longitudes are coming back as incredibly low numbers that can't possibly be right. Like 0.003785746 when I am expecting something closer to the original lat and long values (43.7389, 7.42577). Since I am no master of advanced math, I don't really know what to look for here. Perhaps someone else may have an answer. Here is my complete code: package store_finder; import java.util.Vector; import javax.microedition.location.Criteria; import javax.microedition.location.Location; import javax.microedition.location.LocationException;

You can see the SQL query commented out to know how I plan on using the min and max lat and long values. Any help is appreciated. Thanks

• Referencing movie clips from within an actionscript class

  - by Ant

  Hi all, I have been given the task of adding a scoring system to various flash games. This simply involves taking input, adding functionality such as pausing and replaying and then outputting the score, time left etc. at the end. I've so far successfully edited two games. Both these games used the "actions" code on frames. The latest game I'm trying to do uses an actionscript class which makes it both easier and harder. I'm not very adept at flash at all, but I've worked it out so far. I've added various movie clips that are to be used for displaying the pause screen background, buttons for replaying etc. I've been showing and hiding these using: back._visible = true; //movie clip, instance of back (back.png) I doubt it's best practice, but it's quick and has been working. However, now with the change of coding style to classes, this doesn't seem to work. I kinda understand why, but I'm now unsure how to hide/show these elements. Any help would be greatly appreciated :) I've attached the modified AS. class RivalOrbs extends MovieClip { var infinite_levels, orbs_start, orbs_inc, orbs_per_level, show_timer, _parent, one_time_per_level, speed_start, speed_inc_percent, max_speed, percent_starting_on_wrong_side, colorize, colors, secs_per_level; function RivalOrbs() { super(); mc = this; this.init(); } // End of the function function get_num_orbs() { if (infinite_levels) { return (orbs_start + (level - 1) * orbs_inc); } else if (level > orbs_per_level.length) { return (0); } else { return (orbs_per_level[level - 1]); } // end else if } // End of the function function get_timer_str(secs) { var _loc2 = Math.floor(secs / 60); var _loc1 = secs % 60; return ((_loc2 > 0 ?

• Passing data between android ListActivities in Java

  - by Will Janes

  I am new to Android! I am having a problem getting this code to work... Basically I Go from one list activity to another and pass the text from a list item through the intent of the activity to the new list view, then retrieve that text in the new list activity and then preform a http request based on value of that list item.

• Facebook Oauth Logout

  - by Derek Troy-West

  I have an application that integrates with Facebook using Oauth 2. I can authorize with FB and query their REST and Graph APIs perfectly well, but when I authorize an active browser session is created with FB. I can then log-out of my application just fine, but the session with FB persists, so if anyone else uses the browser they will see the previous users FB account (unless the previous user manually logs out of FB also). The steps I take to authorize are: Call [LINK: graph.facebook.com/oauth/authorize?client_id...] This step opens a Facebook login/connect window if the user's browser doesn't already have an active FB session. Once they log-in to facebook they redirect to my site with a code I can exchange for an oauth token. Call [LINK: graph.facebook.com/oauth/access_token?client_id..] with the code from (1) Now I have an Oauth Token, and the user's browser is logged into my site, and into FB. I call a bunch of APIs to do stuff: i.e. [LINK: graph.facebook.com/me?access_token=..] Lets say my user wants to log out of my site. The FB terms and conditions demand that I perform Single Sign Off, so when the user logs out of my site, they also are logged out of Facebook. There are arguments that this is a bit daft, but I'm happy to comply if there is any way of actually achieving that. I have seen suggestions that: A. I use the Javascript API to logout: FB.Connect.logout(). Well I tried using that, but it didn't work, and I'm not sure exactly how it could, as I don't use the Javascript API in any way on my site. The session isn't maintained or created by the Javascript API so I'm not sure how it's supposed to expire it either. B. Use [LINK: facebook.com/logout.php]. This was suggested by an admin in the Facebook forums some time ago. The example given related to the old way of getting FB sessions (non-oauth) so I don't think I can apply it in my case. C. Use the old REST api expireSession or revokeAuthorization. I tried both of these and while they do expire the Oauth token they don't invalidate the session that the browser is currently using so it has no effect, the user is not logged out of Facebook. I'm really at a bit of a loose end, the Facebook documentation is patchy, ambiguous and pretty poor. The support on the forums is non-existant, at the moment I can't even log in to the facebook forum, and aside from that, their own FB Connect integration doesn't even work on the forum itself. Doesn't inspire much confidence. Ta for any help you can offer. Derek ps. Had to change HTTPS to LINK, not enough karma to post links which is probably fair enough.

• Facebook Connect icon isn't showing up in Internet Explorer

  - by John Duff

  I'm working on a site that is using Facebook Connect and recently made some changes so that the main pages are cached and if you are not logged in (checked with an ajax call) it loads the Facebook Connect javascript and renders the connect button into the page. This works perfectly everywhere except Internet Explorer 7 and 8. The weird part is I render the buttons into a hidden Sign Up / Sign In form and when you show either of those the Connect buttons appear. You can take a look here and you will see the button in Firefox and not Internet Explorer. If you click Sign In the button will show up. This is a Rails app so on the server-side we're responding to an ajax call with rjs like this: page['signin-status'].replace(:partial => "common/layout/signin_menu") page.select('.facebook-connect').each do |value, index| value.replace(render(:partial => '/facebook/signin')) end page << <<-eos LazyLoader.load('http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php', function(){ FB.init('#{Facebooker.api_key}','/xd_receiver.html'); }); eos The first line is replacing the header, the second is the Connect buttons in the Modal dialogs. The partial being rendered into the header looks like this: <span id='signin-status'> <%= fb_login_button(remote_function(:url => "/facebook/connect"))%> | <%= link_to_function "Sign In", "showSignInForm();", :id => "signin" %> | <%= link_to_function "Sign Up", "showSignUpForm();", :id => "signup" %> </span> The Partial being rendered into the Modal dialogs looks like this: <div class='facebook-connect'> <div id="FB_HiddenContainer" style="position:absolute; top:-10000px; width:0px; height:0px;" ></div> <label>Or sign in with your Facebook account</label> <%= fb_login_button(remote_function(:url => "/facebook/connect"))%> </div> I find it very strange that showing the Modal dialog causes all the icons to show. Does anyone have any ideas or suggestions about what's going on?

• Facebook Javascript SDK's FB.ui Bug in IE8

  - by Lukas

  hi everyone i have found a bug in IE8 using the new Facebook Javascript SDK. i call a Post dialog using: FB.ui( { method: 'stream.publish', display: 'dialog', message: 'test', attachment: { name: 'test', caption: 'test', media: [ {type: 'image', src: site_url+'test.jpg', href: site_url} ], description: ( 'test' ), href: site_url } }, my html structure is: <body> <div id="content"></div> <script type="text/javascript"> var params = { wmode: 'opaque', allowScriptAccess: 'always', quality: 'high', allowFullScreen: "true" }; var attributes = { id: 'test' }; swfobject.embedSWF("frontend/swf/stage.swf", "content", "100%", "100%", "10", params, attributes); var site_url = 'http://test.com'; </script> <div id="fb-root"></div> <script type="text/javascript" src="http://connect.facebook.net/en_US/all.js"></script> <div id="like-dialog" style="display:none;"> <div id="like-dialog-wrapper"> <div id="like-dialog-close"></div> <iframe src="http://www.facebook.com/plugins/likebox.php?id=99999999999&amp;width=292&amp;connections=0&amp;stream=true&amp;header=false&amp;height=395" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:292px; height:395px;"></iframe> </div> </div> </body> the css: html, #content, body { margin: 0; height: 100%; overflow: hidden; } #content { z-index: 1; } what i do is: i embed my stage i call the FB.init function and then call FB.ui function to overlay my flash. it works in every common browser except IE8. in IE8 the div containing the iframe is behind the div where i embed flash, although i set the z-index and position the dialog absolute. any ideas? thanks in advance

• qT quncompress gzip data

  - by talei

  Hello, I stumble upon a problem, and can't find a solution. So what I want to do is uncompress data in qt, using qUncompress(QByteArray), send from www in gzip format. I used wireshark to determine that this is valid gzip stream, also tested with zip/rar and both can uncompress it. Code so far, is like this: static const char dat[40] = { 0x1f, 0x8b, 0x08, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x03, 0xaa, 0x2e, 0x2e, 0x49, 0x2c, 0x29, 0x2d, 0xb6, 0x4a, 0x4b, 0xcc, 0x29, 0x4e, 0xad, 0x05, 0x00, 0x00, 0x00, 0xff, 0xff, 0x03, 0x00, 0x2a, 0x63, 0x18, 0xc5, 0x0e, 0x00, 0x00, 0x00 }; //this data contains string: {status:false}, in gzip format QByteArray data; data.append( dat, sizeof(dat) ); unsigned int size = 14; //expected uncompresed size, reconstruct it BigEndianes //prepand expected uncompressed size, last 4 byte in dat 0x0e = 14 QByteArray dataPlusSize; dataPlusSize.append( (unsigned int)((size >> 24) & 0xFF)); dataPlusSize.append( (unsigned int)((size >> 16) & 0xFF)); dataPlusSize.append( (unsigned int)((size >> 8) & 0xFF)); dataPlusSize.append( (unsigned int)((size >> 0) & 0xFF)); QByteArray uncomp = qUncompress( dataPlusSize ); qDebug() << uncomp; And uncompression fails with: qUncompress: Z_DATA_ERROR: Input data is corrupted. AFAIK gzip consist of 10 byte header, DEFLATE peyload, 12 byte trailer ( 8 byte CRC32 + 4 byte ISIZE - uncompresed data size ). Striping header and trailer should leave me with DEFLATE data stream, qUncompress yields same error. I checked with data string compressed in PHP, like this: $stringData = gzcompress( "{status:false}", 1); and qUncompress uncompress that data.(I didn't see and gzip header though i.e. ID1 = 0x1f, ID2 = 0x8b ) I checked above code with debug, and error occurs at: if ( #endif ((BITS(8) << 8) + (hold >> 8)) % 31) { //here is error, WHY? long unsigned int hold = 35615 strm->msg = (char *)"incorrect header check"; state->mode = BAD; break; } inflate.c line 610. I know that qUncompress is simply a wrapper to zlib, so I suppose it should handle gzip without any problem. Any comments are more then welcome. Best regards

• getting autodiscover URL from Exchange email address

  - by Anthony

  I'm starting with an address for an Exchange 2007 server: [email protected] And I attempted to send an autodiscover request, as documented at MSDN. I attempted to use the generic autodiscover address documented at the TechNet White Paper. So, using curl on PHP, I sent the following request: <Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/outlook/requestschema/2006"> <Request> <EMailAddress>[email protected]</EMailAddress> <AcceptableResponseSchema> http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a </AcceptableResponseSchema> </Request> </Autodiscover> to the following URL: https://domain.exchangeserver.org/autodiscover/autodiscover.xml But got no response, just an eventual timeout. I also tried: https://autodiscover.domain.exchangeserver.org/autodiscover/autodiscover.xml With the same result. Now, since my larger goal is to use Autodiscover with Exchange Web Services, and since all of the EWS URLs start with the same sub-domain as the Outlook Web Access address, I thought I'd give that a try: OWA: https://wmail.domain.exchangeserver.org So I tried: https://wmail.domain.exchangeserver.org/autodiscover/autodiscover.xml And sure enough, I got back the expected response. However, I only knew the OWA sub-domain because it's the server I have access to and that I'm using to test everything. I would not know it for sure or be able to guess it if this were a live app and the user was entering in their own Exchange email. I know that whatever generic autodiscover settings must be turned on, because I can enter: [email protected] into Apple Mail on Snow Leopard and it finds everything without trouble. So the question is... Should https://domain.exchangeserver.org/autodiscover/autodiscover.xml have worked, and I just missed a step when trying to connect to it? Or, Is there some trick (maybe involving pinging the email address?) that Apple Mail and other clients use to resolve the address to the OWA subdomain before sending the autodiscover request? Thanks to anyone who knows or can take a wild guess.
