• Stream Music and Video Over the Internet with Windows Media Player 12

  - by DigitalGeekery

  A new feature in Windows Media Player 12, which is included with Windows 7, is being able to stream media over the web to other Windows 7 computers.  Today we will take a look at how to set it up and what you need to begin. Note: You will need to perform this process on each computer that you want to use. What You’ll Need Two computers running Windows 7 Home Premium, Professional, or Ultimate. The host, or home computer that you will be streaming the media from, cannot be on a public network or part of domain. Windows Live ID UPnP or Port Forwarding enabled on your home router Media files added to your Windows Media Player library Windows Live ID Sign up online for a Windows Live ID if you do not already have one. See the link below for a link to Windows Live.   Configuring the Windows 7 Computers Open Windows Media Player and go to the library section. Click on Stream and then “Allow Internet access to home media.”   The Internet Home Media Access pop up window will prompt you to link your Windows Live ID to a user account. Click “Link an online ID.” If you haven’t already installed the Windows Live ID Sign-In Assistant, you will be taken to Microsoft’s website and prompted to download it. Once you have completed the Windows Live download assistant install, you will see Windows Live ID online provider appear in the “Link Online IDs” window. Click on “Link Online ID.” Next, you’ll be prompted for a Windows Live ID and password. Enter your Windows Live ID and password and click “Sign In.” A pop up window will notify you that you have successfully allowed Internet access to home media. Now, you will have to repeat the exact same configuration on the 2nd Windows 7 computer. Once you have completed the same configuration on your 2nd computer, you might also need to configure your home router for port forwarding. If your router supports UPnP, you may not need to manually forward any ports on your router. So, this would be a good time to test your connection. Go to a nearby hotspot, or perhaps a neighbor’s house, and test to see if you can stream your media. If not, you’ll need to manually forward the ports. You can always choose to forward the ports anyway, just in case. Note: We tested on a Linksys WRT54GL router, which supports UPnP, and found we still needed to manually forward the ports. Finding the ports to forward on the router Open Windows Media Player and make sure you are in Library view. Click on “Stream” on the top menu, and select “Allow Internet access to home media.”   On the “Internet Home Media Access” window, click on “Diagnose connections.” The “Internet Streaming Diagnostic Tool” will pop up. Click on “Port forwarding information” near the bottom.   On the “Port Forwarding Information” window you will find both the Internal and External Port numbers you will need to forward on your router. The Internal port number should always be 10245. The external number will be different depending on your computer. Microsoft also recommends forwarding port 443. Configuring the Router Next, you’ll need to configure Port Forwarding on your home router. We will show you the steps for a Linksys WRT54GL router, however, the steps for port forwarding will vary from router to router. On the Linksys configuration page, click on the Administration Tab along the top, click the “Applications & Gaming Tab, and then the “Port Range Forward” tab below it. Under “Application,” type in a name. It can be any name you choose. In both the “Start” and “End” boxes, type the port number. Enter the IP address of your home computer in the IP address column. Click the check box under “Enable.” Do this for both the internal and external port numbers and port 443. When finished, click the “Save Settings” button. Note: It’s highly recommended that you configure your home computer with a static IP address When you’re ready to play your media over the Internet, open up Windows Media Player and look for your host computer and username listed under “Other Libraries.” Click on it expand the list to see your media libraries. Choose a library and a file to play. Now you can enjoy your streaming media over the Internet. Conclusion We found media streaming over the Internet to work fairly well. However, we did see a loss of quality with streaming video. Also, Recorded TV .wtv and dvr-ms files did not play at all.

• Customize your icons in Windows 7 and Vista

  - by Matthew Guay

  Want to change out the icons on your desktop and more?  Personalizing your icons is a great way to make your PC uniquely yours,, and today we show you how to grab unique icons, and default Winnows. to be your own. Change the icon for Computer, Recycle Bin, Network, and your User folder Right-click on the desktop, and select Personalize. Now, click the “Change desktop icons” link on the left sidebar in the Personalization window. The window looks slightly different in Windows Vista, but the link is the same. Select the icon you wish to change, and click the Change Icon button.  In Windows 7, you will also notice a box to choose whether or not to allow themes to change icons, and you can uncheck it if you don’t want themes to change your icon settings. You can select one of the other included icons, or click browse to find the icon you want.  Click Ok when you are finished. Change Folder icons You can easily change the icon on most folders in Windows Vista and 7.  Simply right-click on the folder and select properties. Click the Customize tab, and then click the Change Icon button.  This will open the standard dialog to change your icon, so proceed as normal. This basically just creates a hidden desktop.ini file in the folder containing the following or similar data: [.ShellClassInfo]IconFile=%SystemRoot%\system32\SHELL32.dllIconIndex=20 You could manually create or edit the file if you choose, instead of using the dialogs. Simply create a new text file named desktop.ini with this same information, or edit the existing one.  Change the IconFile line to the location of your icon. If you are pointing to a .ico file you should change the IconIndex line to 0 instead. Note that this isn’t available for all folders, for instance you can’t use this to change the icon for the Windows folder.   In Windows 7, please note that you cannot change the icon of folder inside a library.  So if you are browsing your Documents library and would like to change an icon in that folder, right-click on it and select Open folder location.  Now you can change the icon as above. And if you would like to change a Library’s icon itself, then check out this tutorial: Change Your Windows 7 Library Icons the Easy Way Change the icon of any file type Want to make you files easier to tell apart?  Check out our tutorial on how to simply do this: Change a File Type’s Icon in Windows 7 Change the icon of any Application Shortcut To change the icon of a shortcut on your desktop, start menu, or in Explorer, simply right-click on the icon and select Properties. In the Shortcut tab, click the Change Icon button. Now choose one of the other available icons or click browse to find the icon you want. Change Icons of Running Programs in the Windows 7 taskbar If your computer is running Windows 7, you can customize the icon of any program running in the taskbar!  This only works on applications that are running but not pinned to the taskbar, so if you want to customize a pinned icon you may want to unpin it before customizing it.  But the interesting thing about this trick is that it can customize any icon anything running in the taskbar, including things like Control Panel! Right-click or click and push up to open the jumplist on the icon, and then right-click on the program’s name and select Properties.  Here we are customizing Control Panel, but you can do this on any application icon. Now, click Change Icon as usual. Select an icon you want (We switched the Control Panel icon to the Security Shield), or click Browse to find another icon.  Click Ok when finished, and then close the application window. The next time you open the program (or Control Panel in our example), you will notice your new icon on its taskbar icon. Please note that this only works on applications that are currently running and are not pinned to the taskbar.  Strangely, if the application is pinned to the taskbar, you can still click Properties and change the icon, but the change will not show up. Change the icon on any Drive on your Computer You can easily change the icon on your internal hard drives and portable drives with the free Drive Icon Changer application.  Simply download and unzip the file (link below), and then run the application as administrator by right-clicking on the icon and selecting “Run as administrator”. Now, select the drive that you want to change the icon of, and select your desired icon file. Click Save, and Drive Icon Changer will let you know that the icon has been changed successfully. You will then need to reboot your computer to complete the changes.  Simply click Yes to reboot. Now, our Drive icon is changed from this default image: to a Laptop icon we chose! You can do this to any drive in your computer, or to removable drives such as USB flash drives.  When you change these drives icons, the new icon will appear on any computer you insert the drive into.  Also, if you wish to remove the icon change, simply run the Drive Icon Changer again and remove the icon path. Download Drive Icon Changer This application actually simply creates or edits a hidden Autorun.inf file on the top of your drive.  You can edit or create the file yourself by hand if you’d like; simply include the following information in the file, and save it in the top directory of your drive: [autorun]ICON=[path of your icon] Remove Arrow from shortcut icons Many people don’t like the arrow on the shortcut icon, and there are two easy ways to do this. If you’re running the 32 bit version of Windows Vista or 7, simply use the Vista Shortcut Overlay Remover. If your computer is running the 64 bit version of Windows Vista or 7, use the Ultimate Windows Tweaker instead.  Simply select the Additional Tweaks section, and check the “Remove arrows from Shortcut Icons.” For more info and download links check out this article: Disable Shortcut Icon Arrow Overlay in Windows 7 or Vista Closing: This gives you a lot of ways to customize almost any icon on your computer, so you can make it look just like you want it to.  Stay tuned for more great desktop customization articles from How-to Geek!

• Recover Deleted Files on an NTFS Hard Drive from a Ubuntu Live CD

  - by Trevor Bekolay

  Accidentally deleting a file is a terrible feeling. Not being able to boot into Windows and undelete that file makes that even worse. Fortunately, you can recover deleted files on NTFS hard drives from an Ubuntu Live CD. To show this process, we created four files on the desktop of a Windows XP machine, and then deleted them. We then booted up the same machine with the bootable Ubuntu 9.10 USB Flash Drive that we created last week. Once Ubuntu 9.10 boots up, open a terminal by clicking Applications in the top left of the screen, and then selecting Accessories > Terminal. To undelete our files, we first need to identify the hard drive that we want to undelete from. In the terminal window, type in: sudo fdisk –l and press enter. What you’re looking for is a line that ends with HPSF/NTFS (under the heading System). In our case, the device is “/dev/sda1”. This may be slightly different for you, but it will still begin with /dev/. Note this device name. If you have more than one hard drive partition formatted as NTFS, then you may be able to identify the correct partition by the size. If you look at the second line of text in the screenshot above, it reads “Disk /dev/sda: 136.4 GB, …” This means that the hard drive that Ubuntu has named /dev/sda is 136.4 GB large. If your hard drives are of different size, then this information can help you track down the right device name to use. Alternatively, you can just try them all, though this can be time consuming for large hard drives. Now that you know the name Ubuntu has assigned to your hard drive, we’ll scan it to see what files we can uncover. In the terminal window, type: sudo ntfsundelete <HD name> and hit enter. In our case, the command is: sudo ntfsundelete /dev/sda1 The names of files that can recovered show up in the far right column. The percentage in the third column tells us how much of that file can be recovered. Three of the four files that we originally deleted are showing up in this list, even though we shut down the computer right after deleting the four files – so even in ideal cases, your files may not be recoverable. Nevertheless, we have three files that we can recover – two JPGs and an MPG. Note: ntfsundelete is immediately available in the Ubuntu 9.10 Live CD. If you are in a different version of Ubuntu, or for some other reason get an error when trying to use ntfsundelete, you can install it by entering “sudo apt-get install ntfsprogs” in a terminal window. To quickly recover the two JPGs, we will use the * wildcard to recover all of the files that end with .jpg. In the terminal window, enter sudo ntfsundelete <HD name> –u –m *.jpg which is, in our case, sudo ntfsundelete /dev/sda1 –u –m *.jpg The two files are recovered from the NTFS hard drive and saved in the current working directory of the terminal. By default, this is the home directory of the current user, though we are working in the Desktop folder. Note that the ntfsundelete program does not make any changes to the original NTFS hard drive. If you want to take those files and put them back in the NTFS hard drive, you will have to move them there after they are undeleted with ntfsundelete. Of course, you can also put them on your flash drive or open Firefox and email them to yourself – the sky’s the limit! We have one more file to undelete – our MPG. Note the first column on the far left. It contains a number, its Inode. Think of this as the file’s unique identifier. Note this number. To undelete a file by its Inode, enter the following in the terminal: sudo ntfsundelete <HD name> –u –i <Inode> In our case, this is: sudo ntfsundelete /dev/sda1 –u –i 14159 This recovers the file, along with an identifier that we don’t really care about. All three of our recoverable files are now recovered. However, Ubuntu lets us know visually that we can’t use these files yet. That’s because the ntfsundelete program saves the files as the “root” user, not the “ubuntu” user. We can verify this by typing the following in our terminal window: ls –l We want these three files to be owned by ubuntu, not root. To do this, enter the following in the terminal window: sudo chown ubuntu <Files> If the current folder has other files in it, you may not want to change their owner to ubuntu. However, in our case, we only have these three files in this folder, so we will use the * wildcard to change the owner of all three files. sudo chown ubuntu * The files now look normal, and we can do whatever we want with them. Hopefully you won’t need to use this tip, but if you do, ntfsundelete is a nice command-line utility. It doesn’t have a fancy GUI like many of the similar Windows programs, but it is a powerful tool that can recover your files quickly.

• HPC Server Dynamic Job Scheduling: when jobs spawn jobs

  - by JoshReuben

  HPC Job Types HPC has 3 types of jobs http://technet.microsoft.com/en-us/library/cc972750(v=ws.10).aspx · Task Flow – vanilla sequence · Parametric Sweep – concurrently run multiple instances of the same program, each with a different work unit input · MPI – message passing between master & slave tasks But when you try go outside the box – job tasks that spawn jobs, blocking the parent task – you run the risk of resource starvation, deadlocks, and recursive, non-converging or exponential blow-up. The solution to this is to write some performance monitoring and job scheduling code. You can do this in 2 ways: manually control scheduling - allocate/ de-allocate resources, change job priorities, pause & resume tasks , restrict long running tasks to specific compute clusters Semi-automatically - set threshold params for scheduling. How – Control Job Scheduling In order to manage the tasks and resources that are associated with a job, you will need to access the ISchedulerJob interface - http://msdn.microsoft.com/en-us/library/microsoft.hpc.scheduler.ischedulerjob_members(v=vs.85).aspx This really allows you to control how a job is run – you can access & tweak the following features: max / min resource values whether job resources can grow / shrink, and whether jobs can be pre-empted, whether the job is exclusive per node the creator process id & the job pool timestamp of job creation & completion job priority, hold time & run time limit Re-queue count Job progress Max/ min Number of cores, nodes, sockets, RAM Dynamic task list – can add / cancel jobs on the fly Job counters When – poll perf counters Tweaking the job scheduler should be done on the basis of resource utilization according to PerfMon counters – HPC exposes 2 Perf objects: Compute Clusters, Compute Nodes http://technet.microsoft.com/en-us/library/cc720058(v=ws.10).aspx You can monitor running jobs according to dynamic thresholds – use your own discretion: Percentage processor time Number of running jobs Number of running tasks Total number of processors Number of processors in use Number of processors idle Number of serial tasks Number of parallel tasks Design Your algorithms correctly Finally , don’t assume you have unlimited compute resources in your cluster – design your algorithms with the following factors in mind: · Branching factor - http://en.wikipedia.org/wiki/Branching_factor - dynamically optimize the number of children per node · cutoffs to prevent explosions - http://en.wikipedia.org/wiki/Limit_of_a_sequence - not all functions converge after n attempts. You also need a threshold of good enough, diminishing returns · heuristic shortcuts - http://en.wikipedia.org/wiki/Heuristic - sometimes an exhaustive search is impractical and short cuts are suitable · Pruning http://en.wikipedia.org/wiki/Pruning_(algorithm) – remove / de-prioritize unnecessary tree branches · avoid local minima / maxima - http://en.wikipedia.org/wiki/Local_minima - sometimes an algorithm cant converge because it gets stuck in a local saddle – try simulated annealing, hill climbing or genetic algorithms to get out of these ruts   watch out for rounding errors – http://en.wikipedia.org/wiki/Round-off_error - multiple iterations can in parallel can quickly amplify & blow up your algo ! Use an epsilon, avoid floating point errors,  truncations, approximations Happy Coding !

• Now Available &ndash; Windows Azure SDK 1.6

  - by Shaun

  Microsoft has just announced the Windows Azure SDK 1.6 and the Windows Azure Tools for Visual Studio 1.6. Now people can download the latest product through the WebPI. After you downloaded and installed the SDK you will find that The SDK 1.6 can be stayed side by side with the SDK 1.5, which means you can still using the 1.5 assemblies. But the Visual Studio Tools would be upgraded to 1.6. Different from the previous SDK, in this version it includes 4 components: Windows Azure Authoring Tools, Windows Azure Emulators, Windows Azure Libraries for .NET 1.6 and the Windows Azure Tools for Microsoft Visual Studio 2010. There are some significant upgrades in this version, which are Publishing Enhancement: More easily connect to the Windows Azure when publish your application by retrieving a publish setting file. It will let you configure some settings of the deployment, without getting back to the developer portal. Multi-profiles: The publish settings, cloud configuration files, etc. will be stored in one or more MSBuild files. It will be much easier to switch the settings between vary build environments. MSBuild Command-line Build Support. In-Place Upgrade Support.   Publishing Enhancement So let’s have a look about the new features of the publishing. Just create a new Windows Azure project in Visual Studio 2010 with a MVC 3 Web Role, and right-click the Windows Azure project node in the solution explorer, then select Publish, we will find the new publish dialog. In this version the first thing we need to do is to connect to our Windows Azure subscription. Click the “Sign in to download credentials” link, we will be navigated to the login page to provide the Live ID. The Windows Azure Tool will generate a certificate file and uploaded to the subscriptions those belong to us. Then we will download a PUBLISHSETTINGS file, which contains the credentials and subscriptions information. The Visual Studio Tool will generate a certificate and deployed to the subscriptions you have as the Management Certificate. The VS Tool will use this certificate to connect to the subscription in the next step. In the next step, I would back to the Visual Studio (the publish dialog should be stilling opened) and click the Import button, select the PUBLISHSETTINGS file I had just downloaded. Then all my subscriptions will be shown in the dropdown list. Select a subscription that I want the application to be published and press the Next button, then we can select the hosted service, environment, build configuration and service configuration shown in the dialog. In this version we can create a new hosted service directly here rather than go back to the developer portal. Just select the <Create New …> item in the hosted service. What we need to do is to provide the hosted service name and the location. Once clicked the OK, after several seconds the hosted service will be established. If we went to the developer portal we will find the new hosted service in my subscription. a) Currently we cannot select the Affinity Group when create a new hosted service through the Visual Studio Publish dialog. b) Although we can specify the hosted service name and DNS prefixing through the developer portal, we cannot do so from the VS Tool, which means the DNS prefixing would be the same as what we specified for the hosted service name. For example, we specified our hosted service name as “Sdk16Demo”, so the public URL would be http://sdk16demo.cloudapp.net/. After created a new hosted service we can select the cloud environment (production or staging), the build configuration (release or debug), and the service configuration (cloud or local). And we can set the Remote Desktop by check the related checkbox as well. One thing should be note is that, in this version when we set the Remote Desktop settings we don’t need to specify a certificate by default. This is because the Visual Studio will generate a new certificate for us by default. But we can still specify an existing certificate for RDC, by clicking the “More Options” button. Visual Studio Tool will create another certificate for the Remote Desktop connection. It will NOT use the certificate that managing the subscription. We also can select the “Advanced Settings” page to specify the deployment label, storage account, IntelliTrace and .NET profiling information, etc.. Press Next button, the dialog will display all settings I had just specified and it will save them as a new profile. The last step is to click the Publish button. Since we enabled the Remote Desktop feature, the first step of publishing was uploading the certificate. And then it will verify the storage account we specified and upload the package, then finally created the website in Windows Azure.   Multi-Profiles After published, if we back to the Visual Studio we can find a AZUREPUBXML file under the Profiles folder in the Azure project. It includes all settings we specified before. If we publish this project again, we can just use the current settings (hosted service, environment, RDC, etc.) from this profile without input them again. And this is very useful when we have more than one deployment settings. For example it would be able to have one AZUREPUBXML profile for deploying to testing environment (debug building, less roles with RDC and IntelliTrace) and one for production (release building, more roles but without IntelliTrace).   In-Place Upgrade Support Let’s change some codes in the MVC pages and click the Publish menu from the azure project node. No need to specify any settings,  here we can use the pervious settings by loading the azure profile file (AZUREPUBXML). After clicked the Publish button the VS Tool brought a dialog to us to indicate that there’s a deployment available in the hosted service environment, and prompt to REPLACE it or not. Notice that in this version, the dialog tool said “replace” rather than “delete”, which means by default the VS Tool will use In-Place Upgrade when we deploy to a hosted service that has a deployment already exist. After click Yes the VS Tool will upload the package and perform the In-Place Upgrade. If we back to the developer portal we can find that the status of the hosted service was turned to “Updating…”. But in the previous SDK, it will try to delete the whole deployment and publish a new one.   Summary When the Microsoft announced the features that allows the changing VM size via In-Place Upgrade, they also mentioned that in the next few versions the user experience of publishing the azure application would be improved. The target was trying to accomplish the whole publish experience in Visual Studio, which means no need to touch developer portal any more. In the SDK 1.6 we can see from the new publish dialog, as a developer we can do the whole process, includes creating hosted service, specifying the environment, configuration, remote desktop, etc. values without going back the the developer portal.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• A Small Utility to Delete Files recursively by Date

  - by Rick Strahl

  It's funny, but for me the following seems to be a recurring theme: Every few months or years I end up with a host of files on my server that need pruning selectively and often under program control. Today I realized that my SQL Server logs on my server were really piling up and nearly ran my backup drive out of drive space. So occasionally I need to check on that server drive and clean out files. Now with a bit of work this can be done with PowerShell or even a complicated DOS batch file, but heck, to me it's always easier to just create a small Console application that handles this sort of thing with a full command line parser and a few extra options, plus in the end I end up with code that I can actually modify and add features to as is invariably the case. No more searching for a script each time :-) So for my typical copy needs the requirements are: Need to recursively delete files Need to be able to specify a filespec (ie. *.bak) Be able to specify a cut off date before which to delete files And it'd be nice to have an option to send files to the Recycle bin just in case for operator error :-)(and yes that came in handy as I blew away my entire database backup folder by accident - oops!) The end result is a small Console file copy utility that I popped up on Github: https://github.com/RickStrahl/DeleteFiles The source code is up there along with the binary file you can just run. Creating DeleteFiles It's pretty easy to create a simple utility like DeleteFiles of course, so I'm not going to spend any talking about how it works. You can check it out in the repository or download and compile it. The nice thing about using a full programming language like C over something like PowerShell or batch file is that you can make short work of the recursive tree walking that's required to make this work. There's very little code, but there's also a very small, self-contained command line parser in there that might be useful that can be plugged into any project - I've been using it quite a bit for just about any Console application I've been building. If you're like me and don't have the patience or the persistence (that funky syntax requires some 'sticking with it' that I simply can't get over) to get into Powershell coding, having an executable file that I can just copy around or keep in my Utility directory is the only way I'll ever get to reuse this functionality without going on a wild search each time :-) Anyway, hope some of you might find this useful. © Rick Strahl, West Wind Technologies, 2005-2012Posted in Windows  CSharp   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Where should I start with debugging my exchange server?

  - by joadha

  I'm (foolishly?) attempting to install Exchange on top of Windows Server 2008 (64-bit) over Virtual Box running on Mac OSX Lion. Everything went smoothly until I got to the "Readiness Checks" tab. Readiness failed spectacularly on Hub Transport Role and Mailbox Role prereqs. Before I go too far down the rabbit hole in attempting to remedy this, I was hoping I could get some input on where to start in all of this. I already set up the following Active Directory roles, but it didn't seem to help: Active Directory Domain Services Active Directory Lightweight Directory Services I also enabled an Application Server role. Those three are the only roles I've set up-- I cannot locate within Server Manager the Organization Manager role or any of the other roles referenced in the list of borkedness below. Is this a typical experience in Exchange installation? Is there a tutorial created by somebody outside of Microsoft?

• How do you keep code with continuations/callbacks readable?

  - by Heinzi

  Summary: Are there some well-established best-practice patterns that I can follow to keep my code readable in spite of using asynchronous code and callbacks? I'm using a JavaScript library that does a lot of stuff asynchronously and heavily relies on callbacks. It seems that writing a simple "load A, load B, ..." method becomes quite complicated and hard to follow using this pattern. Let me give a (contrived) example. Let's say I want to load a bunch of images (asynchronously) from a remote web server. In C#/async, I'd write something like this: disableStartButton(); foreach (myData in myRepository) { var result = await LoadImageAsync("http://my/server/GetImage?" + myData.Id); if (result.Success) { myData.Image = result.Data; } else { write("error loading Image " + myData.Id); return; } } write("success"); enableStartButton(); The code layout follows the "flow of events": First, the start button is disabled, then the images are loaded (await ensures that the UI stays responsive) and then the start button is enabled again. In JavaScript, using callbacks, I came up with this: disableStartButton(); var count = myRepository.length; function loadImage(i) { if (i >= count) { write("success"); enableStartButton(); return; } myData = myRepository[i]; LoadImageAsync("http://my/server/GetImage?" + myData.Id, function(success, data) { if (success) { myData.Image = data; } else { write("error loading image " + myData.Id); return; } loadImage(i+1); } ); } loadImage(0); I think the drawbacks are obvious: I had to rework the loop into a recursive call, the code that's supposed to be executed in the end is somewhere in the middle of the function, the code starting the download (loadImage(0)) is at the very bottom, and it's generally much harder to read and follow. It's ugly and I don't like it. I'm sure that I'm not the first one to encounter this problem, so my question is: Are there some well-established best-practice patterns that I can follow to keep my code readable in spite of using asynchronous code and callbacks?

• More Great Improvements to the Windows Azure Management Portal

  - by ScottGu

  Over the last 3 weeks we’ve released a number of enhancements to the new Windows Azure Management Portal.  These new capabilities include: Localization Support for 6 languages Operation Log Support Support for SQL Database Metrics Virtual Machine Enhancements (quick create Windows + Linux VMs) Web Site Enhancements (support for creating sites in all regions, private github repo deployment) Cloud Service Improvements (deploy from storage account, configuration support of dedicated cache) Media Service Enhancements (upload, encode, publish, stream all from within the portal) Virtual Networking Usability Enhancements Custom CNAME support with Storage Accounts All of these improvements are now live in production and available to start using immediately.  Below are more details on them: Localization Support The Windows Azure Portal now supports 6 languages – English, German, Spanish, French, Italian and Japanese. You can easily switch between languages by clicking on the Avatar bar on the top right corner of the Portal: Selecting a different language will automatically refresh the UI within the portal in the selected language: Operation Log Support The Windows Azure Portal now supports the ability for administrators to review the “operation logs” of the services they manage – making it easy to see exactly what management operations were performed on them.  You can query for these by selecting the “Settings” tab within the Portal and then choosing the “Operation Logs” tab within it.  This displays a filter UI that enables you to query for operations by date and time: As of the most recent release we now show logs for all operations performed on Cloud Services and Storage Accounts.  You can click on any operation in the list and click the “Details” button in the command bar to retrieve detailed status about it.  This now makes it possible to retrieve details about every management operation performed. In future updates you’ll see us extend the operation log capability to apply to all Windows Azure Services – which will enable great post-mortem and audit support. Support for SQL Database Metrics You can now monitor the number of successful connections, failed connections and deadlocks in your SQL databases using the new “Dashboard” view provided on each SQL Database resource: Additionally, if the database is added as a “linked resource” to a Web Site or Cloud Service, monitoring metrics for the linked SQL database are shown along with the Web Site or Cloud Service metrics in the dashboard. This helps with viewing and managing aggregated information across both resources in your application. Enhancements to Virtual Machines The most recent Windows Azure Portal release brings with it some nice usability improvements to Virtual Machines: Integrated Quick Create experience for Windows and Linux VMs Creating a new Windows or Linux VM is now easy using the new “Quick Create” experience in the Portal: In addition to Windows VM templates you can also now select Linux image templates in the quick create UI: This makes it incredibly easy to create a new Virtual Machine in only a few seconds. Enhancements to Web Sites Prior to this past month’s release, users were forced to choose a single geographical region when creating their first site.  After that, subsequent sites could only be created in that same region.  This restriction has now been removed, and you can now create sites in any region at any time and have up to 10 free sites in each supported region: One of the new regions we’ve recently opened up is the “East Asia” region.  This allows you to now deploy sites to North America, Europe and Asia simultaneously.  Private GitHub Repository Support This past week we also enabled Git based continuous deployment support for Web Sites from private GitHub and BitBucket repositories (previous to this you could only enable this with public repositories).  Enhancements to Cloud Services Experience The most recent Windows Azure Portal release brings with it some nice usability improvements to Cloud Services: Deploy a Cloud Service from a Windows Azure Storage Account The Windows Azure Portal now supports deploying an application package and configuration file stored in a blob container in Windows Azure Storage. The ability to upload an application package from storage is available when you custom create, or upload to, or update a cloud service deployment. To upload an application package and configuration, create a Cloud Service, then select the file upload dialog, and choose to upload from a Windows Azure Storage Account: To upload an application package from storage, click the “FROM STORAGE” button and select the application package and configuration file to use from the new blob storage explorer in the portal. Configure Windows Azure Caching in a caching enabled cloud service If you have deployed the new dedicated cache within a cloud service role, you can also now configure the cache settings in the portal by navigating to the configuration tab of for your Cloud Service deployment. The configuration experience is similar to the one in Visual Studio when you create a cloud service and add a caching role.  The portal now allows you to add or remove named caches and change the settings for the named caches – all from within the Portal and without needing to redeploy your application. Enhancements to Media Services You can now upload, encode, publish, and play your video content directly from within the Windows Azure Portal.  This makes it incredibly easy to get started with Windows Azure Media Services and perform common tasks without having to write any code. Simply navigate to your media service and then click on the “Content” tab.  All of the media content within your media service account will be listed here: Clicking the “upload” button within the portal now allows you to upload a media file directly from your computer: This will cause the video file you chose from your local file-system to be uploaded into Windows Azure.  Once uploaded, you can select the file within the content tab of the Portal and click the “Encode” button to transcode it into different streaming formats: The portal includes a number of pre-set encoding formats that you can easily convert media content into: Once you select an encoding and click the ok button, Windows Azure Media Services will kick off an encoding job that will happen in the cloud (no need for you to stand-up or configure a custom encoding server).  When it’s finished, you can select the video in the “Content” tab and then click PUBLISH in the command bar to setup an origin streaming end-point to it: Once the media file is published you can point apps against the public URL and play the content using Windows Azure Media Services – no need to setup or run your own streaming server.  You can also now select the file and click the “Play” button in the command bar to play it using the streaming endpoint directly within the Portal: This makes it incredibly easy to try out and use Windows Azure Media Services and test out an end-to-end workflow without having to write any code.  Once you test things out you can of course automate it using script or code – providing you with an incredibly powerful Cloud Media platform that you can use. Enhancements to Virtual Network Experience Over the last few months, we have received feedback on the complexity of the Virtual Network creation experience. With these most recent Portal updates, we have added a Quick Create experience that makes the creation experience very simple. All that an administrator now needs to do is to provide a VNET name, choose an address space and the size of the VNET address space. They no longer need to understand the intricacies of the CIDR format or walk through a 4-page wizard or create a VNET / subnet. This makes creating virtual networks really simple: The portal also now has a “Register DNS Server” task that makes it easy to register DNS servers and associate them with a virtual network. Enhancements to Storage Experience The portal now lets you register custom domain names for your Windows Azure Storage Accounts.  To enable this, select a storage resource and then go to the CONFIGURE tab for a storage account, and then click MANAGE DOMAIN on the command bar: Clicking “Manage Domain” will bring up a dialog that allows you to register any CNAME you want: Summary The above features are all now live in production and available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using them today.  Visit the Windows Azure Developer Center to learn more about how to build apps with it. One of the other cool features that is now live within the portal is our new Windows Azure Store – which makes it incredibly easy to try and purchase developer services from a variety of partners.  It is an incredibly awesome new capability – and something I’ll be doing a dedicated post about shortly. 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

• Is there an appropriate coding style for implementing an algorithm during an interview?

  - by GlenPeterson

  I failed an interview question in C years ago about converting hex to decimal by not exploiting the ASCII table if (inputDigitByte > 9) hex = inputDigitByte - 'a'. The rise of Unicode has made this question pretty silly, but the point was that the interviewer valued raw execution speed above readability and error handling. They tell you to review algorithms textbooks to prepare for these interviews, yet these same textbooks tend to favor the implementation with the fewest lines of code, even if it has to rely on magic numbers (like "infinity") and a slower, more memory-intensive implementation (like a linked list instead of an array) to do that. I don't know what is right. Coding an algorithm within the space of an interview has at least 3 constraints: time to code, elegance/readability, and efficiency of execution. What trade-offs are appropriate for interview code? How much do you follow the textbook definition of an algorithm? Is it better to eliminate recursion, unroll loops, and use arrays for efficiency? Or is it better to use recursion and special values like "infinity" or Integer.MAX_VALUE to reduce the number of lines of code needed to write the algorithm? Interface: Make a very self-contained, bullet-proof interface, or sloppy and fast? On the one extreme, the array to be sorted might be a public static variable. On the other extreme, it might need to be passed to each method, allowing methods to be called individually from different threads for different purposes. Is it appropriate to use a linked-list data structure for items that are traversed in one direction vs. using arrays and doubling the size when the array is full? Implementing a singly-linked list during the interview is often much faster to code and easier remember for recursive algorithms like MergeSort. Thread safety - just document that it's unsafe, or say so verbally? How much should the interviewee be looking for opportunities for parallel processing? Is bit shifting appropriate? x / 2 or x >> 1 Polymorphism, type safety, and generics? Comments? Variable and method names: qs(a, p, q, r) vs: quickSort(theArray, minIdx, partIdx, maxIdx) How much should you use existing APIs? Obviously you can't use a java.util.HashMap to implement a hash-table, but what about using a java.util.List to accumulate your sorted results? Are there any guiding principals that would answer these and other questions, or is the guiding principal to ask the interviewer? Or maybe this should be the basis of a discussion while writing the code? If an interviewer can't or won't answer one of these questions, are there any tips for coaxing the information out of them?

• MiniMax function throws null pointer exception

  - by Sven

  I'm working on a school project, I have to build a tic tac toe game with the AI based on the MiniMax algorithm. The two player mode works like it should. I followed the code example on http://ethangunderson.com/blog/minimax-algorithm-in-c/. The only thing is that I get a NullPointer Exception when I run the code. And I can't wrap my finger around it. I placed a comment in the code where the exception is thrown. The recursive call is returning a null pointer, what is very strange because it can't.. When I place a breakpoint on the null return with the help of a if statement, then I see that there ARE still 2 to 3 empty places.. I probably overlooking something. Hope someone can tell me what I'm doing wrong. Here is the MiniMax code (the tic tac toe code is not important): /* * To change this template, choose Tools | Templates * and open the template in the editor. */ package MiniMax; import Game.Block; import Game.Board; import java.util.ArrayList; public class MiniMax { public static Place getBestMove(Board gameBoard, Block.TYPE player) { Place bestPlace = null; ArrayList<Place> emptyPlaces = gameBoard.getEmptyPlaces(); Board newBoard; //loop trough all the empty places for(Place emptyPlace : emptyPlaces) { newBoard = gameBoard.clone(); newBoard.setBlock(emptyPlace.getRow(), emptyPlace.getCell(), player); //no game won and still room to move if(newBoard.getWinner() == Block.TYPE.NONE && newBoard.getEmptyPlaces().size() > 0) { //is an node (has children) Place tempPlace = getBestMove(newBoard, invertPlayer(player)); //ERROR is thrown here! tempPlace is null. emptyPlace.setScore(tempPlace.getScore()); } else { //is an leaf if(newBoard.getWinner() == Block.TYPE.NONE) { emptyPlace.setScore(0); } else if(newBoard.getWinner() == Block.TYPE.X) { emptyPlace.setScore(-1); } else if(newBoard.getWinner() == Block.TYPE.O) { emptyPlace.setScore(1); } //if this move is better then our prev move, take it! if((bestPlace == null) || (player == Block.TYPE.X && emptyPlace.getScore() < bestPlace.getScore()) || (player == Block.TYPE.O && emptyPlace.getScore() > bestPlace.getScore())) { bestPlace = emptyPlace; } } } //This should never be null, but it does.. return bestPlace; } private static Block.TYPE invertPlayer(Block.TYPE player) { if(player == Block.TYPE.X) { return Block.TYPE.O; } return Block.TYPE.X; } }

• Organizing Git repositories with common nested sub-modules

  - by André Caron

  I'm a big fan of Git sub-modules. I like to be able to track a dependency along with its version, so that you can roll-back to a previous version of your project and have the corresponding version of the dependency to build safely and cleanly. Moreover, it's easier to release our libraries as open source projects as the history for libraries is separate from that of the applications that depend on them (and which are not going to be open sourced). I'm setting up workflow for multiple projects at work, and I was wondering how it would be if we took this approach a bit of an extreme instead of having a single monolithic project. I quickly realized there is a potential can of worms in really using sub-modules. Supposing a pair of applications: studio and player, and dependent libraries core, graph and network, where dependencies are as follows: core is standalone graph depends on core (sub-module at ./libs/core) network depdends on core (sub-module at ./libs/core) studio depends on graph and network (sub-modules at ./libs/graph and ./libs/network) player depends on graph and network (sub-modules at ./libs/graph and ./libs/network) Suppose that we're using CMake and that each of these projects has unit tests and all the works. Each project (including studio and player) must be able to be compiled standalone to perform code metrics, unit testing, etc. The thing is, a recursive git submodule fetch, then you get the following directory structure: studio/ studio/libs/ (sub-module depth: 1) studio/libs/graph/ studio/libs/graph/libs/ (sub-module depth: 2) studio/libs/graph/libs/core/ studio/libs/network/ studio/libs/network/libs/ (sub-module depth: 2) studio/libs/network/libs/core/ Notice that core is cloned twice in the studio project. Aside from this wasting disk space, I have a build system problem because I'm building core twice and I potentially get two different versions of core. Question How do I organize sub-modules so that I get the versioned dependency and standalone build without getting multiple copies of common nested sub-modules? Possible solution If the the library dependency is somewhat of a suggestion (i.e. in a "known to work with version X" or "only version X is officially supported" fashion) and potential dependent applications or libraries are responsible for building with whatever version they like, then I could imagine the following scenario: Have the build system for graph and network tell them where to find core (e.g. via a compiler include path). Define two build targets, "standalone" and "dependency", where "standalone" is based on "dependency" and adds the include path to point to the local core sub-module. Introduce an extra dependency: studio on core. Then, studio builds core, sets the include path to its own copy of the core sub-module, then builds graph and network in "dependency" mode. The resulting folder structure looks like: studio/ studio/libs/ (sub-module depth: 1) studio/libs/core/ studio/libs/graph/ studio/libs/graph/libs/ (empty folder, sub-modules not fetched) studio/libs/network/ studio/libs/network/libs/ (empty folder, sub-modules not fetched) However, this requires some build system magic (I'm pretty confident this can be done with CMake) and a bit of manual work on the part of version updates (updating graph might also require updating core and network to get a compatible version of core in all projects). Any thoughts on this?

• Creating SharePoint sites from xml using Powershell

  - by Norgean

  It is frequently useful to create / delete web applications in a development environment. If you need to create a structure, this can quickly become tedious. Enter Powershell, xml and recursive functions. Create the structure in xml. Something like: <Sites>     <Site Name="Test 1" Url="Test1" />     <Site Name="Test 2" Url="Test2" >         <Site Name="Test 2 1" Url="Test21" >             <Site Name="Test 2 1 1" Url="Test211" />             <Site Name="Test 2 1 2" Url="Test212" />         </Site>     </Site>     <Site Name="Test 3" Url="Test3" >         <Site Name="Test 3 1" Url="Test31" />         <Site Name="Test 3 2" Url="Test32" />         <Site Name="Test 3 3" Url="Test33" >             <Site Name="Test 3 3 1" Url="Test331" />             <Site Name="Test 3 3 2" Url="Test332" />         </Site>         <Site Name="Test 3 4" Url="Test34" />     </Site> </Sites> Read this structure in Powershell, and recursively create the sites. Oh, and have cool progress dialogs, too. $snap = Get-PSSnapin | Where-Object { $_.Name -eq "Microsoft.SharePoint.Powershell" } if ($snap -eq $null) {     Add-PSSnapin "Microsoft.SharePoint.Powershell" } function CreateSites($baseUrl, $sites, [int]$progressid) {     $sitecount = $sites.ChildNodes.Count     $counter = 0     foreach ($site in $sites.Site)     {         Write-Progress -ID $progressid -Activity "Creating sites" -status "Creating $($site.Name)" -percentComplete ($counter / $sitecount*100)         $counter = $counter + 1         Write-Host "Creating $($site.Name) $($baseUrl)/$($site.Url)"         New-SPWeb -Url "$($baseUrl)/$($site.Url)" -AddToQuickLaunch:$false -AddToTopNav:$false -Confirm:$false -Name "$($site.Name)" -Template "STS#0" -UseParentTopNav:$true         if ($site.ChildNodes.Count -gt 0)         {             CreateSites "$($baseUrl)/$($site.Url)" $site ($progressid +1)         }         Write-Progress -ID $progressid -Activity "Creating sites" -status "Creating $($site.Name)" -Completed     } } # read an xml file $xml = [xml](Get-Content "C:\Projects\Powershell\sites.xml") $xml.PreserveWhitespace = $false CreateSites "http://$($env:computername)" $xml.Sites 1 Easy! Sensible real life implementations will also include templateid in the xml, will check for existence of a site before creating it, etc.

• Finding work as a college student

  - by lightburst

  I'm a 3rd year CS student. I'm currently really, really, bored and tired of cheap school programming(I go to a fairly respectable(albeit not top) university in my country, but, really, it's not MIT) so I've been thinking about getting a part-time dev job for a long while now. I'm not some hotshot programmer or anything, but "Add/Delete XYZ class objects to list" or "Do this web feature/pattern in PHP" does get old after a few semesters. I also only learned(heard?) of programming when I entered college, so the duration of me being in contact with any code is short. I can't really apply as an intern as I have not accumulated the necessary credits yet to do that so I was thinking of selling myself as a part-time dev. I still need to go to school, and don't want to subject myself to living two lives. Plus, I think I'd have better chances considering my lack of things to write on the resume. The only language I know at heart is C (I've written several pointer-oriented stuff on my freshman year, which is apparently pretty leet(for some reason), or so Joel says. That sort of boosted my morale a bit) but I've worked with several other languages only for the sake of course work such as C#/Java/PHP/ASM. My only user-worthy project was a recursive quicksort simulator I wrote for class using GTK+ that used a textbox to output the progress. I also have not taken the compiler theory class yet, or my thesis. All that being said, I wonder if any legitimate software company(big or small) would hire somebody like me considering all that. If there are companies that do accept anybody like me, would I be doing programming or maybe just be a tester or something? Would anybody hire me as a dev at all? I know I don't have much(not even a degree) but what I lack in experience, I compensate with interest? I am less interested in websites and 'management' software(no offense or anything. also, most of the places here ONLY have those), and more into 'process driven'(I'm not sure how to call it) and system software. I have my eyes on a startup that sells basically an extension of Google Drive, but I feel like I'm too 'risky' for them. Oh, I'm also 19 if that means anything. We're not K-12 so kids go to college earlier than in the US.

• How to make sprint planning fun

  - by Jacob Spire

  Not only are our sprint planning meetings not fun, they're downright dreadful. The meetings are tedious, and boring, and take forever (a day, but it feels like a lot longer). The developers complain about it, and dread upcoming plannings. Our routine is pretty standard (user story inserted into sprint backlog by priority story is taken apart to tasks tasks are estimated in hours repeat), and I can't figure out what we're doing wrong. How can we make the meetings more enjoyable? ... Some more details, in response to requests for more information: Why are the backlog items not inserted and prioritized before sprint kickoff? User stories are indeed prioritized; we have no idea how long they'll take until we break them down into tasks! From the (excellent) answers here, I see that maybe we shouldn't estimate tasks at all, only the user stories. The reason we estimate tasks (and not stories) is because we've been getting story-estimates terribly wrong -- but I guess that's the subject for an altogether different question. Why are developers complaining? Meetings are long. Meetings are monotonous. Story after story, task after task, struggling (yes, struggling) to estimate how long it will take and what it involves. Estimating tasks makes user-story-estimation seem pointless. The longer the meeting, the less focus in the room. The less focused colleagues are, the longer the meeting takes. A recursive hate-spiral develops. We've considered splitting the meeting into two days in order to keep people focused, but the developers wouldn't hear of it. One day of planning is bad enough; now we'll have two?! Part of our problem is that we go into very small detail (in order to get more accurate estimations). But when we estimate roughly, we go way off the mark! To sum up the question: What are we doing wrong? What additional ways are there to make the meeting generally more enjoyable?

• INS-40719 error when Install Oracle RAC?

  - by Data-Base

  I'm tying to (learn how to) install Oracle RAC 11g on CentOS 6 all went OK so far but I get INS-40719 Error message regarding SCAN Name I do not have DNS server and I'm not going to try to use it on this setup I add this line to /etc/hosts 192.168.244.100 rac-cluster then used "rac-cluster" as the SCAN name and it's still not working with the same error message! any one can guide me on how to make it work? 1- do I have to add "192.168.244.100 rac-cluster" to /etc/hosts on both nodes? 2- do I need to edit/add any thing else on the nodes? cheers

• How to resolve "svn: Can't find a temporary directory: Internal error"?

  - by HorusKol

  I have already googled the message, and I have plenty of disk space available on the SVN server (it's about 4% usage of 150 GB). I have noticed that when I try echo $TMPDIR at the command prompt on the SVN server I get nothing. What is making this a little confusing is that I only get this message from one location when I do an svn diff (that I've tested so far) - this error is not coming up when I try from three other computers (one of which is testing against the exact same repository, the other two are different repositories on the same svn server). About the only difference I can see is that the broken working copy is connecting to the server by an IP address where all the others are using a server name (although this resolves over DNS to the same IP Address). I'm hoping that I don't have to scratch the broken working copy and checkout a new one - unfortunately, this is a legacy project and not all changes have been properly revisioned.

• FIM 2010 GAL MA - It appears this forest is not exchange enabled.

  - by WooYek

  I am trying to configure a Management Agent (MA) for Global Address List (GAL) sync in FIM 2010. I cannot move to the next step from "Configure GAL" because of an error message saying "It appears this forest is not exchange enabled". Nothing I change on "Configure GAL" step is changing this behavior. I'am configuring a standalone test lab. I have a Windows 2008 R2 x64 Server, promoted to a DC and SQL 2008 SP1 installed, DNS is also running locally. I have tried to install Exchange 2010 and 2007, but there is no difference. AD MA works fine. Any ideas what did I screw up?

• Static IP settings on Windows 2003 server not getting saved

  - by Prashant Mandhare

  We have a Dell PowerEgde 1950 server with Broadcom NetXtreme gigabit ethernet card, and we are facing a strange problem with static IP assignment. When we assign a static IP to this broadcom NIC, settings are not getting saved. Following are the steps to reproduce problem open TCP/IP properties window for broadcom NIC manually enter static IP address and other details like gateway, DNS, etc. apply and close properties dialog. re-open TCP/IP properties windows, you will see your static IP settings lost and changed to "obtain IP address manually" but when checked using ipconfig command, you will still see your same static IP settings but, when checked using ipconfig command after rebooting server, these static ip settings are completely gone and automatically obtained IP is assigned Supplementary information: Recently we had formatted this server and installed windows 2003 from OEM windows setup CD (not from OS installation CD received from Dell). After windows installation was over, broadcom NIC drivers were installed.

• ASA hairpining: I basicaly want to allow 2 spokes to be able to communicate with each other.

  - by Thirst4Knowledge

  ASA Spoke to Spoke Communication I have been looking at spke to spoke comms or "hairpining" for months and have posted on numerouse forums but to no avail. I have a Hub and spoke network where the HUB is an ASA Firewall version 8.2 * I basicaly want to allow 2 spokes to be able to communicate with each other. I think that I have got the concept of the ASA Config for example: same-security-traffic permit intra-interface access-list HQ-LAN extended permit ip ASA-LAN 255.255.248.0 HQ-LAN 255.255.255.0 access-list HQ-LAN extended permit ip 192.168.99.0 255.255.255.0 HQ-LAN 255.255.255.0 access-list no-nat extended permit ip ASA_LAN 255.255.248.0 HQ-LAN 255.255.255.0 access-list no-nat extended permit ip HQ-LAN 255.255.255.0 192.168.99.0 255.255.255.0 access-list no-nat extended permit ip 192.168.99.0 255.255.255.0 HQ-LAN 255.255.255.0 I think my problem may be that the other spokes are not CIsco Firewalls and I need to work out how to do the alternative setups. I want to at least make sure that my firewall etup is correct then I can move onto the other spokes here is my config: Hostname ASA domain-name mydomain.com names ! interface Ethernet0/0 speed 100

• What can cause a DirectAccess IPSec Main Mode Error "no policy configured"

  - by Mike Haboustak

  We have Microsoft's DirectAccess VPN set up on Server 2008 R2 with end-to-edge security, and we're having trouble with the manage-out tunnel. The DirectAccess client has DC/DNS and intranet connectivity, it can ping/rdp/etc to intranet hosts. However connections originating from those same intranet hosts can only intermittently reach the client. At times it works fine, other times it doesn't. When an inbound (intranet to client) connection is attempted there's an IPSec Main Mode failure logged: Event 4653 with a failure reason of "No Policy Configured". I think that it may be related to the state of the intranet (corp) access tunnel, and an overlap in the configured subnets for those polices. I haven't figured out exactly what's different in the scenario where the connection works and where it does not.
