• Numerous Unexpected Obstacles Ruining any Project Plans

  - by Libor

  I am working as software developer and struggling with this problem time and time again for almost thirteen years. There seems not to be any way out of the following problem. And it happens with small projects as well. For example, I plan to write an extension for Microsoft Visual Studio. I dowload learning materials, get some book on the topic and allocate time for learning and development. However, during the development, many seemingly trivial problems arise, for example: Why the script refuses to delete the file? Why Visual Studio does not register the extension? (after two days) OK, it registers it, but now it got broken. How to fix it? each of these "small" obstacles usually take 1-5 days to resolve and the project finally consumes several times more man-hours than planned. Maybe it happens only because I am working on Microsoft platform and many of their Frameworks and architectures are bit confusing and badly documented. I would like to have most problems resolved by finding answer in a book or official documentation (MSDN), but the only answer I usually find is on some weird forum or personal blog googled after desperately searching for any relevant information on the topic. Do you have the same struggles? Do you have techniques on how to prevent these problems? I was thinking of simply multiplying projected time for a given project by some factor, but this does not help. Some projects get done briskly and some take months and the guiding factor here are these small "glitches" which take programmers whole weeks to resolve. I have to admit that lots of these obstacles demoralizes me and drains me of focus and joy of work (who likes to get back to work when he have to resolve some stupid registry problem or weird framework bug instead of doing creative work?) After the project is finally done, I am feeling like dying from thousand cuts.

• Windows Azure: Announcing release of Windows Azure SDK 2.2 (with lots of goodies)

  - by ScottGu

  Earlier today I blogged about a big update we made today to Windows Azure, and some of the great new features it provides. Today I’m also excited to also announce the release of the Windows Azure SDK 2.2. Today’s SDK release adds even more great features including: Visual Studio 2013 Support Integrated Windows Azure Sign-In support within Visual Studio Remote Debugging Cloud Services with Visual Studio Firewall Management support within Visual Studio for SQL Databases Visual Studio 2013 RTM VM Images for MSDN Subscribers Windows Azure Management Libraries for .NET Updated Windows Azure PowerShell Cmdlets and ScriptCenter The below post has more details on what’s available in today’s Windows Azure SDK 2.2 release.  Also head over to Channel 9 to see the new episode of the Visual Studio Toolbox show that will be available shortly, and which highlights these features in a video demonstration. Visual Studio 2013 Support Version 2.2 of the Window Azure SDK is the first official version of the SDK to support the final RTM release of Visual Studio 2013. If you installed the 2.1 SDK with the Preview of Visual Studio 2013 we recommend that you upgrade your projects to SDK 2.2.  SDK 2.2 also works side by side with the SDK 2.0 and SDK 2.1 releases on Visual Studio 2012: Integrated Windows Azure Sign In within Visual Studio Integrated Windows Azure Sign-In support within Visual Studio is one of the big improvements added with this Windows Azure SDK release.  Integrated sign-in support enables developers to develop/test/manage Windows Azure resources within Visual Studio without having to download or use management certificates.  You can now just right-click on the “Windows Azure” icon within the Server Explorer inside Visual Studio and choose the “Connect to Windows Azure” context menu option to connect to Windows Azure: Doing this will prompt you to enter the email address of the account you wish to sign-in with: You can use either a Microsoft Account (e.g. Windows Live ID) or an Organizational account (e.g. Active Directory) as the email.  The dialog will update with an appropriate login prompt depending on which type of email address you enter: Once you sign-in you’ll see the Windows Azure resources that you have permissions to manage show up automatically within the Visual Studio Server Explorer (and you can start using them): With this new integrated sign in experience you are now able to publish web apps, deploy VMs and cloud services, use Windows Azure diagnostics, and fully interact with your Windows Azure services within Visual Studio without the need for a management certificate.  All of the authentication is handled using the Windows Azure Active Directory associated with your Windows Azure account (details on this can be found in my earlier blog post). Integrating authentication this way end-to-end across the Service Management APIs + Dev Tools + Management Portal + PowerShell automation scripts enables a much more secure and flexible security model within Windows Azure, and makes it much more convenient to securely manage multiple developers + administrators working on a project.  It also allows organizations and enterprises to use the same authentication model that they use for their developers on-premises in the cloud.  It also ensures that employees who leave an organization immediately lose access to their company’s cloud based resources once their Active Directory account is suspended. Filtering/Subscription Management Once you login within Visual Studio, you can filter which Windows Azure subscriptions/regions are visible within the Server Explorer by right-clicking the “Filter Services” context menu within the Server Explorer.  You can also use the “Manage Subscriptions” context menu to mange your Windows Azure Subscriptions: Bringing up the “Manage Subscriptions” dialog allows you to see which accounts you are currently using, as well as which subscriptions are within them: The “Certificates” tab allows you to continue to import and use management certificates to manage Windows Azure resources as well.  We have not removed any functionality with today’s update – all of the existing scenarios that previously supported management certificates within Visual Studio continue to work just fine.  The new integrated sign-in support provided with today’s release is purely additive. Note: the SQL Database node and the Mobile Service node in Server Explorer do not support integrated sign-in at this time. Therefore, you will only see databases and mobile services under those nodes if you have a management certificate to authorize access to them.  We will enable them with integrated sign-in in a future update. Remote Debugging Cloud Resources within Visual Studio Today’s Windows Azure SDK 2.2 release adds support for remote debugging many types of Windows Azure resources. With live, remote debugging support from within Visual Studio, you are now able to have more visibility than ever before into how your code is operating live in Windows Azure.  Let’s walkthrough how to enable remote debugging for a Cloud Service: Remote Debugging of Cloud Services To enable remote debugging for your cloud service, select Debug as the Build Configuration on the Common Settings tab of your Cloud Service’s publish dialog wizard: Then click the Advanced Settings tab and check the Enable Remote Debugging for all roles checkbox: Once your cloud service is published and running live in the cloud, simply set a breakpoint in your local source code: Then use Visual Studio’s Server Explorer to select the Cloud Service instance deployed in the cloud, and then use the Attach Debugger context menu on the role or to a specific VM instance of it: Once the debugger attaches to the Cloud Service, and a breakpoint is hit, you’ll be able to use the rich debugging capabilities of Visual Studio to debug the cloud instance remotely, in real-time, and see exactly how your app is running in the cloud. Today’s remote debugging support is super powerful, and makes it much easier to develop and test applications for the cloud.  Support for remote debugging Cloud Services is available as of today, and we’ll also enable support for remote debugging Web Sites shortly. Firewall Management Support with SQL Databases By default we enable a security firewall around SQL Databases hosted within Windows Azure.  This ensures that only your application (or IP addresses you approve) can connect to them and helps make your infrastructure secure by default.  This is great for protection at runtime, but can sometimes be a pain at development time (since by default you can’t connect/manage the database remotely within Visual Studio if the security firewall blocks your instance of VS from connecting to it). One of the cool features we’ve added with today’s release is support that makes it easy to enable and configure the security firewall directly within Visual Studio.  Now with the SDK 2.2 release, when you try and connect to a SQL Database using the Visual Studio Server Explorer, and a firewall rule prevents access to the database from your machine, you will be prompted to add a firewall rule to enable access from your local IP address: You can simply click Add Firewall Rule and a new rule will be automatically added for you. In some cases, the logic to detect your local IP may not be sufficient (for example: you are behind a corporate firewall that uses a range of IP addresses) and you may need to set up a firewall rule for a range of IP addresses in order to gain access. The new Add Firewall Rule dialog also makes this easy to do.  Once connected you’ll be able to manage your SQL Database directly within the Visual Studio Server Explorer: This makes it much easier to work with databases in the cloud. Visual Studio 2013 RTM Virtual Machine Images Available for MSDN Subscribers Last week we released the General Availability Release of Visual Studio 2013 to the web.  This is an awesome release with a ton of new features. With today’s Windows Azure update we now have a set of pre-configured VM images of VS 2013 available within the Windows Azure Management Portal for use by MSDN customers.  This enables you to create a VM in the cloud with VS 2013 pre-installed on it in with only a few clicks: Windows Azure now provides the fastest and easiest way to get started doing development with Visual Studio 2013. Windows Azure Management Libraries for .NET (Preview) Having the ability to automate the creation, deployment, and tear down of resources is a key requirement for applications running in the cloud.  It also helps immensely when running dev/test scenarios and coded UI tests against pre-production environments. Today we are releasing a preview of a new set of Windows Azure Management Libraries for .NET.  These new libraries make it easy to automate tasks using any .NET language (e.g. C#, VB, F#, etc).  Previously this automation capability was only available through the Windows Azure PowerShell Cmdlets or to developers who were willing to write their own wrappers for the Windows Azure Service Management REST API. Modern .NET Developer Experience We’ve worked to design easy-to-understand .NET APIs that still map well to the underlying REST endpoints, making sure to use and expose the modern .NET functionality that developers expect today: Portable Class Library (PCL) support targeting applications built for any .NET Platform (no platform restriction) Shipped as a set of focused NuGet packages with minimal dependencies to simplify versioning Support async/await task based asynchrony (with easy sync overloads) Shared infrastructure for common error handling, tracing, configuration, HTTP pipeline manipulation, etc. Factored for easy testability and mocking Built on top of popular libraries like HttpClient and Json.NET Below is a list of a few of the management client classes that are shipping with today’s initial preview release: .NET Class Name Supports Operations for these Assets (and potentially more) ManagementClient Locations Credentials Subscriptions Certificates ComputeManagementClient Hosted Services Deployments Virtual Machines Virtual Machine Images & Disks StorageManagementClient Storage Accounts WebSiteManagementClient Web Sites Web Site Publish Profiles Usage Metrics Repositories VirtualNetworkManagementClient Networks Gateways Automating Creating a Virtual Machine using .NET Let’s walkthrough an example of how we can use the new Windows Azure Management Libraries for .NET to fully automate creating a Virtual Machine. I’m deliberately showing a scenario with a lot of custom options configured – including VHD image gallery enumeration, attaching data drives, network endpoints + firewall rules setup - to show off the full power and richness of what the new library provides. We’ll begin with some code that demonstrates how to enumerate through the built-in Windows images within the standard Windows Azure VM Gallery.  We’ll search for the first VM image that has the word “Windows” in it and use that as our base image to build the VM from.  We’ll then create a cloud service container in the West US region to host it within: We can then customize some options on it such as setting up a computer name, admin username/password, and hostname.  We’ll also open up a remote desktop (RDP) endpoint through its security firewall: We’ll then specify the VHD host and data drives that we want to mount on the Virtual Machine, and specify the size of the VM we want to run it in: Once everything has been set up the call to create the virtual machine is executed asynchronously In a few minutes we’ll then have a completely deployed VM running on Windows Azure with all of the settings (hard drives, VM size, machine name, username/password, network endpoints + firewall settings) fully configured and ready for us to use: Preview Availability via NuGet The Windows Azure Management Libraries for .NET are now available via NuGet. Because they are still in preview form, you’ll need to add the –IncludePrerelease switch when you go to retrieve the packages. The Package Manager Console screen shot below demonstrates how to get the entire set of libraries to manage your Windows Azure assets: You can also install them within your .NET projects by right clicking on the VS Solution Explorer and using the Manage NuGet Packages context menu command.  Make sure to select the “Include Prerelease” drop-down for them to show up, and then you can install the specific management libraries you need for your particular scenarios: Open Source License The new Windows Azure Management Libraries for .NET make it super easy to automate management operations within Windows Azure – whether they are for Virtual Machines, Cloud Services, Storage Accounts, Web Sites, and more.  Like the rest of the Windows Azure SDK, we are releasing the source code under an open source (Apache 2) license and it is hosted at https://github.com/WindowsAzure/azure-sdk-for-net/tree/master/libraries if you wish to contribute. PowerShell Enhancements and our New Script Center Today, we are also shipping Windows Azure PowerShell 0.7.0 (which is a separate download). You can find the full change log here. Here are some of the improvements provided with it: Windows Azure Active Directory authentication support Script Center providing many sample scripts to automate common tasks on Windows Azure New cmdlets for Media Services and SQL Database Script Center Windows Azure enables you to script and automate a lot of tasks using PowerShell.  People often ask for more pre-built samples of common scenarios so that they can use them to learn and tweak/customize. With this in mind, we are excited to introduce a new Script Center that we are launching for Windows Azure. You can learn about how to scripting with Windows Azure with a get started article. You can then find many sample scripts across different solutions, including infrastructure, data management, web, and more: All of the sample scripts are hosted on TechNet with links from the Windows Azure Script Center. Each script is complete with good code comments, detailed descriptions, and examples of usage. Summary Visual Studio 2013 and the Windows Azure SDK 2.2 make it easier than ever to get started developing rich cloud applications. Along with the Windows Azure Developer Center’s growing set of .NET developer resources to guide your development efforts, today’s Windows Azure SDK 2.2 release should make your development experience more enjoyable and efficient. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• Changing the default installation path to a newly installed hard disk

  - by mgj

  Hi, I am currently working on a dual-booted PC. I am using Windows XP and Ubuntu 10.04 Lucid Lynx released in April 2010. The allocated partition to Ubuntu that I am making use of has almost exhausted. Current memory allocations on the PC wrt Ubuntu OS looks like this: bodhgaya@pc146724-desktop:~$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 8.6G 8.0G 113M 99% / none 998M 268K 998M 1% /dev none 1002M 580K 1002M 1% /dev/shm none 1002M 100K 1002M 1% /var/run none 1002M 0 1002M 0% /var/lock none 1002M 0 1002M 0% /lib/init/rw /dev/sda1 25G 16G 9.8G 62% /media/C /dev/sdb1 37G 214M 35G 1% /media/ubuntulinuxstore bodhgaya@pc146724-desktop:~$ cd /tmp I am trying to mount a 40GB(/dev/sdb1 - given below) new hard disk along with my existing Ubuntu system to overcome with hard disk space related issues. I referred to the following tutorial to mount a new hard disk onto the system:- http://www.smorgasbord.net/how-to-in...untu-linux%20/ I was able to successfully mount this hard disk for Ubuntu 0S. I have this new hard disk setup in /media/ubuntulinuxstore directory. The current partition in my system looks like this: bodhgaya@pc146724-desktop:/media/ubuntulinuxstore$ sudo fdisk -l [sudo] password for bodhgaya: Disk /dev/sda: 40.0 GB, 40000000000 bytes 255 heads, 63 sectors/track, 4863 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x446eceb5 Device Boot Start End Blocks Id System /dev/sda1 * 2 3264 26210047+ 7 HPFS/NTFS /dev/sda2 3265 4385 9004432+ 83 Linux /dev/sda3 4386 4863 3839535 82 Linux swap / Solaris Disk /dev/sdb: 40.0 GB, 40000000000 bytes 255 heads, 63 sectors/track, 4863 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xfa8afa8a Device Boot Start End Blocks Id System /dev/sdb1 1 4862 39053983+ 7 HPFS/NTFS bodhgaya@pc146724-desktop:/media/ubuntulinuxstore$ Now, I have a concern wrt the "location" where the new softwares will be installed. Generally softwares are installed via the terminal and by default a fixed path is used to where the post installation set up files can be found (I am talking in context of the drive). This is like the typical case of Windows, where softwares by default are installed in the C: drive. These days people customize their installations to a drive which they find apt to serve their purpose (generally based on availability of hard disk space). I am trying to figure out how to customize the same for Ubuntu. As we all know the most softwares are installed via commands given from the Terminal. My road block is how do I redirect the default path set on the terminal where files get installed to this new hard disk. This if done will help me overcome space constraints I am currently facing wrt the partition on which my Ubuntu is initially installed. I would also by this, save time on not formatting my system and reinstalling Ubuntu and other softwares all over again. Please help me with this, your suggestions are much appreciated.

• OpenFilesView Displays All Open and Locked Files to Help Resolve In-Use Errors

  - by Jason Fitzpatrick

  Windows: You go to move a file and Windows throws up an “In Use” error. OpenFilesView shows you what application or system process is locking up the files you’re trying to move. Sometimes the culprit is obvious; if you go to move your media folder and you’ve got your media player open watching South Park then shutting down the media player is the obvious solution. Other times the culprit is less obvious; sometimes Windows processes and less-than-obvious applications are accessing your files in ways that aren’t apparent. The screenshot below showcases the “In Use” error: This is where OpenFilesView comes into play. Fire up the application to see a list of all active files on your system. The master list is a bit overwhelming (on our test system there were over 1200 open files) but you use the find command to drill down to specific file or folder names. Once you’ve found the locked file you can close the file handle, kill the process, or bring the process to the front (so you can examine the program, if possible, before terminating it). It’s much more efficient than rebooting in an attempt to shake the In-Use error. OpenFilesView is freeware and works on Windows XP through Windows 7.

• Transitioning from Oracle based CMS to MySQL based CMS

  - by KM01

  We're looking at a replacement for our CMS which runs on Oracle. The new CMSes that we've looked at can in theory run on Oracle, but most of the vendor's installs run off of MySQL vendor supports install of their CMS on MySQL, and a "theoretical" install on Oracle the vendor's dev shops use MySQL none of them develop/test against Oracle Our DBA team works exclusively with Oracle, and doesn't have the bandwidth to provide additional support for a highly available and performing MySQL setup. They could in theory go to training and get ramped up, but our time line is also short (surprise!). So ... I guess my question(s) are: If you've seen a situation like this, how have you dealt with it? What tipped the balance either way? What type of effort did it take? If you're to do it over, what would you do differently ... ? Thanks! KM

• Does it work when a developer is the project manager's boss?

  - by marabutt

  I am in the planning stage of a project and I am looking to hire a project manager. I would like to do some coding and keep eye on all parts of the project. However, i have a feeling that a project manager will get better results. I have the following options: 1) manage the project and not code 2) hire a project manager and code myself I am worried that the project manager will feel impeded by having the project owner in the development team. If I run the project, the team might fall apart causing the project to fail. To stick within budget, I have to be involved in one capacity or another. Does anyone have experience with this situation, any suggestions? more info: 4 in-house developers each responsible for a specific area. The developers can also outsource work if agreed to by the project manager.

• Login failed for user 'sa' because the account is currently locked out. The system administrator can

  - by cabhilash

  Login failed for user 'sa' because the account is currently locked out. The system administrator can unlock it. (Microsoft SQL Server, Error: 18486) SQL server has local password policies. If policy is enabled which locks down the account after X number of failed attempts then the account is automatically locked down.This error with 'sa' account is very common. sa is default administartor login available with SQL server. So there are chances that an ousider has tried to bruteforce your system. (This can cause even if a legitimate tries to access the account with wrong password.Sometimes a user would have changed the password without informing others. So the other users would try to lo) You can unlock the account with the following options (use another admin account or connect via windows authentication) Alter account & unlock ALTER LOGIN sa WITH PASSWORD='password' UNLOCK Use another account Almost everyone is aware of the sa account. This can be the potential security risk. Even if you provide strong password hackers can lock the account by providing the wrong password. ( You can provide extra security by installing firewall or changing the default port but these measures are not always practical). As a best practice you can disable the sa account and use another account with same privileges.ALTER LOGIN sa DISABLE You can edit the lock-ot options using gpedit.msc( in command prompt type gpedit.msc and press enter). Navigate to Account Lokout policy as shown in the figure The Following options are available Account lockout threshold This security setting determines the number of failed logon attempts that causes a user account to be locked out. A locked-out account cannot be used until it is reset by an administrator or until the lockout duration for the account has expired. You can set a value between 0 and 999 failed logon attempts. If you set the value to 0, the account will never be locked out. Failed password attempts against workstations or member servers that have been locked using either CTRL+ALT+DELETE or password-protected screen savers count as failed logon attempts. Account lockout duration This security setting determines the number of minutes a locked-out account remains locked out before automatically becoming unlocked. The available range is from 0 minutes through 99,999 minutes. If you set the account lockout duration to 0, the account will be locked out until an administrator explicitly unlocks it. If an account lockout threshold is defined, the account lockout duration must be greater than or equal to the reset time. Default: None, because this policy setting only has meaning when an Account lockout threshold is specified. Reset account lockout counter after This security setting determines the number of minutes that must elapse after a failed logon attempt before the failed logon attempt counter is reset to 0 bad logon attempts. The available range is 1 minute to 99,999 minutes. If an account lockout threshold is defined, this reset time must be less than or equal to the Account lockout duration. Default: None, because this policy setting only has meaning when an Account lockout threshold is specified.When creating SQL user you can set CHECK_POLICY=on which will enforce the windows password policy on the account. The following policies will be applied Define the Enforce password history policy setting so that several previous passwords are remembered. With this policy setting, users cannot use the same password when their password expires.  Define the Maximum password age policy setting so that passwords expire as often as necessary for your environment, typically, every 30 to 90 days. With this policy setting, if an attacker cracks a password, the attacker only has access to the network until the password expires.  Define the Minimum password age policy setting so that passwords cannot be changed until they are more than a certain number of days old. This policy setting works in combination with the Enforce password historypolicy setting. If a minimum password age is defined, users cannot repeatedly change their passwords to get around the Enforce password history policy setting and then use their original password. Users must wait the specified number of days to change their passwords.  Define a Minimum password length policy setting so that passwords must consist of at least a specified number of characters. Long passwords--seven or more characters--are usually stronger than short ones. With this policy setting, users cannot use blank passwords, and they have to create passwords that are a certain number of characters long.  Enable the Password must meet complexity requirements policy setting. This policy setting checks all new passwords to ensure that they meet basic strong password requirements.  Password must meet the following complexity requirement, when they are changed or created: Not contain the user's entire Account Name or entire Full Name. The Account Name and Full Name are parsed for delimiters: commas, periods, dashes or hyphens, underscores, spaces, pound signs, and tabs. If any of these delimiters are found, the Account Name or Full Name are split and all sections are verified not to be included in the password. There is no check for any character or any three characters in succession. Contain characters from three of the following five categories:  English uppercase characters (A through Z) English lowercase characters (a through z) Base 10 digits (0 through 9) Non-alphabetic characters (for example, !, $, #, %) A catch-all category of any Unicode character that does not fall under the previous four categories. This fifth category can be regionally specific.

• How do I (tactfully) tell my project manager or lead developer that the project's codebase needs serious work?

  - by Adam Maras

  I just joined a (relatively) small development team that's been working on a project for several months, if not a year. As with most developer joining a project, I spent my first couple of days reviewing the project's codebase. The project (a medium- to large-sized ASP.NET WebForms internal line of business application) is, for lack of a more descriptive term, a disaster. There are three immediately noticeable problems with the coding standards: The standard is very loose. It describes more of what not to do (don't use Hungarian notation, etc..) than what to do. The standard isn't always followed. There are inconsistencies with the code formatting everywhere. The standard doesn't follow Microsoft's style guidelines. In my opinion, there's no value in deviating from the guidelines that were set forth by the developer of the framework and the largest contributor to the language specification. As for point 3, perhaps it bothers me more because I've taken the time to get my MCPD with a focus on web applications (specifically, ASP.NET). I'm also the only Microsoft Certified Professional on the team. Because of what I learned in all of my schooling, self-teaching, and on-the-job learning (including my preparation for the certification exams) I've also spotted several instances in the project's code where things are simply not done in the best way. I've only been on this team for a week, but I see so many issues with their codebase that I imagine I'll be spending more time fighting with what's already written to do things in "their way" than I would if I were working on a project that, for example, followed more widely accepted coding standards, architecture patterns, and best practices. This brings me to my question: Should I (and if so, how do I) propose to my project manager and team lead that the project needs to be majorly renovated? I don't want to walk into their office, waving my MCTS and MCPD certificates around, saying that their project's codebase is crap. But I also don't want to have to stay silent and have to write kludgey code atop their kludgey code, because I actually want to write quality software and I want the end product to be stable and easily maintainable.

• Maintaining Revision Levels

  - by kyle.hatlestad

  A question that came up on an earlier blog post was how to limit the number of revisions on a piece of content. UCM does not inherently enforce any sort of limit on how many revisions you can have. It's unlimited. In some cases, there may be content that goes through lots of changes, but there just simply isn't a need to keep all of its revisions around. Deleting those revisions through the content information screen can be very cumbersome. And going through the Repository Manager applet can take time as well to filter and find the revisions to get rid of. But there is an easier way through the Archiver. The Export Query criteria in Archiver includes a very handy field called 'Revision Rank'. With revision labels, they typically go up as new revisions come in (e.g. 1, 2, 3, 4, etc...). But you can't really use this field to tell it to keep the top 5 revisions. Those top 5 revision numbers are always going up. But revision rank goes the opposite direction. The very latest revision is always 0. The previous revision to that is 1. Previous revision to that is 2. And so on and so forth. With revision rank, you can set your query to look for any Revision Rank greater or equal to 5. Now as older revisions move down the line, their revision rank gets higher and higher until they reach that threshold. Then when you run that archive export, you can choose to delete and remove those revisions. Running that export in Archiver is normally a manual process. But with Idc Command, you can script the process and have it run automatically from the server. Idc Command is a utility that allows you to run any of the content server services via the command line. You basically feed it a text file with the services and parameters defined along with the user to run it as. The Idc Command executable is located within the \bin\ directory: $ ./IdcCommand -f DeleteOlderRevisions.txt -u sysadmin -l delete_revisions.log In this example, our IdcCommand file to run the export and do the deletions would look like: IdcService=EXPORT_ARCHIVE aArchiveName=DeleteOlderRevisions aDoDelete=1 IDC_Name=idc dataSource=RevisionIDs <<EOD>> You can then use automated scheduling routines in the OS to run the command and command file at the frequency needed. Remember that you are deleting the revisions from within UCM, but they are still getting placed within the archive. So you will need to delete those batches to have them fully removed (or re-import if you need to recover them). For more information about Idc Command, you can find that in the Idc Command Reference Guide.

• SQL Server v.Next (Denali) : More on contained databases and "contained users"

  - by AaronBertrand

  One of the reasons for contained databases (see my previous post ) is to allow for a more seamless transition when moving a database from one server to another. One of the biggest complications in doing so is making sure that all of the logins are in place on the new server. Contained databases help solve this issue by creating a new type of user: a database-level user with a password. I want to stress that this is not the same concept as a user without a login , which serves a completely different...(read more)

  I'm writing a small research paper which involves software development methodologiess. I was looking into all the available methodology's and I was wondering, from all methodologies, are there any that have provided the foundations for the others? For an example, looking at the following methodologies: Agile, Prototyping, Cleanroom, Iterative, RAD, RUP, Spiral, Waterfall, XP, Lean, Scrum, V-Model, TDD. Can we say that: Prototyping, Iterative, Spiral and Waterfall are the "foundation" for the others? Or is there no such thing as "foundations" and does each methodology has it's own unique history? I would ofcourse like to describe all the methodology's in my research paper, but I simply don't have the time to do so and that is why I would like to know which methodologies can be seen as representatives.

• Master Data Services Employees Sample Model

  - by Davide Mauri

  I’ve been playing with Master Data Services quite a lot in those last days and I’m also monitoring the web for all available resources on it. Today I’ve found this freshly released sample available on MSDN Code Gallery: SQL Server Master Data Services Employee Sample Model http://code.msdn.microsoft.com/SSMDSEmployeeSample This sample shows how Recursive Hierarchies can be modeled in order to represent a typical organizational chart scenario where a self-relationship exists on the Employee entity.

• How to name a bug?

  - by Pieter

  Bugs usually receive a descriptive name: "That X-Y synchronization issue", "That crash after actions A, B and D but not C", "Yesterday's update problem". Even the JIRA issue tracker has a field "Summary" instead of "Name". In discussing "big" bugs, I actually use JIRA id's to prevent confusion. There's a few restrictions to take into account: When reporting a bug, only the consequence of a bug is known. The root cause might never even be found. Several reported bugs might be found out to be duplicates, or might be completely different consequences of the same bug. In large projects, bugs will come at you by the dozens every month. Now, how would you name a bug? Name them like hurricanes perhaps?

• dpkg E: Sub-process /usr/bin/dpkg returned an error

  - by user81269

  I decided to shift around my partitions on my hard drive for a fresh install of Kubuntu. I booted my Ubuntu 10.10 live disc, shifted everything around and attempted to install grub and it didn't work, so I burnt an Ubuntu 12.04 disc and installed it. I got the computer working and wanted to install some packages, but didn't have an internet connection at the time. So (I know this was stupid) I got some debs from previous versions of Ubuntu, as I needed my music, and the other install took a long of time to boot. Once I got my internet connection back, everything worked ok, for a little while. Then I stumbled upon this problem after removing ten broken packages using synaptic: drhax@Spamotard:~$ sudo apt-get install -f Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED: libgtk2.0-cil 0 upgraded, 0 newly installed, 1 to remove and 417 not upgraded. 1 not fully installed or removed.

• The Oracle Retail Week Awards - most exciting awards yet?

  - by sarah.taylor(at)oracle.com

  Last night's annual Oracle Retail Week Awards saw the UK's top retailers come together to celebrate the very best of our industry over the last year.  The Grosvenor House Hotel on Park Lane in London was the setting for an exciting ceremony which this year marked several significant milestones in British - and global - retail.  Check out our videos about the event at our Oracle Retail YouTube channel, and see if you were snapped by our photographer on our Oracle Retail Facebook page. There were some extremely hot contests for many of this year's awards - and all very deserving winners.  The entries have demonstrated beyond doubt that retailers have striven to push their standards up yet again in all areas over the past year.  The judging panel includes some of the most prestigious names in the retail industry - to impress the panel enough to win an award is a substantial achievement.  This year the panel included the likes of Andy Clarke - Chief Executive of ASDA Group; Mark Newton Jones - CEO of Shop Direct Group; Richard Pennycook - the finance director at Morrisons; Rob Templeman - Chief Executive of Debenhams; and Stephen Sunnucks - the president of Gap Europe.  These are retail veterans  who have each helped to shape the British High Street over the last decade.  It was great to chat with many of them in the Oracle VIP area last night.  For me, last night's highlight was honouring both Sir Stuart Rose and Sir Terry Leahy for their contributions to the retail industry.  Both have set the standards in retailing over the last twenty years and taken their respective businesses from strength to strength, demonstrating that there is always a need for innovation even in larger businesses, and that a business has to adapt quickly to new technology in order to stay competitive.  Sir Terry Leahy's retirement this year marks the end of an era of global expansion for the Tesco group and a milestone in the progression of British retail.  Sir Terry has helped steer Tesco through nearly 20 years of change, with 14 years as Chief Executive.  During this time he led the drive for international expansion and an aggressive campaign to increase market share.  He has led the way for High Street retailers in adapting to the rise of internet retailing and nurtured a very successful home delivery service.  More recently he has pioneered the notion of cross-channel retailing with the introduction of Tesco apps for the iPhone and Android mobile phones allowing customers to scan barcodes of items to add to a shopping list which they can then either refer to in store or order for delivery.  John Lewis Partnership was a very deserving winner of The Oracle Retailer of the Year award for their overall dedication to excellent retailing practices.  The business was also named the American Express Marketing/Advertising Campaign of the Year award for their memorable 'Never Knowingly Undersold' advert series, which included a very successful viral video and radio campaign with Fyfe Dangerfield's cover of Billy Joel's 'She's Always a Woman' used for the adverts.  Store Design of the Year was another exciting category with Topshop taking the accolade for its flagship Oxford Street store in London, which combines boutique concession-style stalls with high fashion displays and exclusive collections from leading designers.  The store even has its own hairdressers and food hall, making it a truly all-inclusive fashion retail experience and a global landmark for any self-respecting international fashion shopper. Over the next few weeks we'll be exploring some of the winning entries in more detail here on the blog, so keep an eye out for some unique insights into how the winning retailers have made such remarkable achievements.

• A Primer on Migrating Oracle Applications to a New Platform

  - by Nick Quarmby

  In Support we field a lot of questions about the migration of Oracle Applications to different platforms.  This article describes the techniques available for migrating an Oracle Applications environment to a new platform and discusses some of the common questions that arise during migration.  This subject has been frequently discussed in previous blog articles but there still seems to be a gap regarding the type of questions we are frequently asked in Service Requests. Some of the questions we see are quite abstract. Customers simply want to get a grip on understanding how they approach a migration. Others want to know if a particular architecture is viable. Other customers ask about mixing different platforms within a single Oracle Applications environment.    Just to clarify, throughout this article, the term 'platform' refers specifically to operating systems and not to the underlying hardware. For a clear definition of 'platform' in the context of Oracle Applications Support then Terri's very timely article:Oracle E-Business Suite Platform SmörgåsbordThe migration process is very similar for both 11i and R12 so this article only mentions specific differences where relevant.

• How to solve package issues/dependencies

  - by Wolfgang Kuehne

  Background info I am trying to install Veins simulation environment by following the tutorial provided by the author. In step 1 it is required to install some packages in Linux, the tutorial suggest this commands to be executed on Terminal: sudo apt-get install build-essential gcc g++ bison flex perl tcl-dev tk-dev blt libxml2-dev zlib1g-dev default-jre doxygen graphviz libwebkitgtk-1.0-0 openmpi-bin libopenmpi-dev libpcap-dev autoconf automake libtool libxerces-c2-dev proj libgdal1-dev libfox-1.6-dev When I execute this command, I immediately get: E: Package 'proj' has no installation candidate Then I remove the proj from the command and execute it again without proj in it, next I get: The following packages have unmet dependencies: libgdal1-dev : Depends: libgdal-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. So, I remove libgdal1-dev from the command as well. And it executes file, by downloading the remaining packages. To troubleshoot the problem with proj and libdgal1-dev I go to the Synaptic Package Manager. libgdal1-dev I search for libgdal1-dev in Synaptic Package Manager and I get an entry. I Mark for Installation and then Synaptic Package Manager suggests removing libxerces-c2-dev which is actually added via the initial command. Should I trust Synaptic Package Manager with this suggestion, and proceed further? proj What should I do about proj. There are some packages in Synaptic Package Manager such as proj-bin or libproj-dev. Should I install them? I think proj has to do with this and this What should I do to make sure that this simulation tool works fine?

• What, if anything, to do about bow-shaped burndowns?

  - by Karl Bielefeldt

  I've started to notice a recurring pattern to our team's burndown charts, which I call a "bowstring" pattern. The ideal line is the "string" and the actual line starts out relatively flat, then curves down to meet the target like a bow. My theory on why they look like this is that toward the beginning of the story, we are doing a lot of debugging or exploratory work that is difficult to estimate remaining work for. Sometimes it even goes up a little as we discover a task is more difficult once we get into it. Then we get into implementation and test which is more predictable, hence the curving down graph. Note I'm not talking about a big scale like BDUF, just the natural short-term constraint that you have to find the bug before you can fix it, coupled with the fact that stories are most likely to start toward the beginning of a two-week iteration. Is this a common occurrence among scrum teams? Do people see it as a problem? If so, what is the root cause and some techniques to deal with it?
