• Impressions of Pivotal Tracker

  Pivotal Tracker is a free, online agile project management system. Ive been using it recently to better communicate to customers about the current state of our project. In Pivotal Tracker, the unit of work is a story and stories are arranged into iterations or delivery cycles. Stories can be any level of granularity you want, but the idea is to use stories to communicate clearly to customers, so you dont want to write a novel. You especially dont want to write a list of detailed programming tasks. A good story for a point of sale system might be: Allow managers to override the price of an item while ringing up a customer. A less useful story: Script out the process of adding a manager flag to the user table and stage that script into the deploy directory. Stories are estimated using a point scale, by default 1, 2 or 3. Iterations are then automatically laid out by combining enough tasks to fill the point total for that period of time. You have to start with a guess on how many points your team can do in an iteration, then adjust with real data as you complete iterations. This is basic agile methodology, but where Pivotal Tracker adds value is that it automatically and graphically lays out iterations for you on your project site. This makes communication and planning easy. Compiling release notes is no longer painful as it has been clear from the outset what work is going on. While I much prefer Pivotal Trackers customer facing interface over what we used previously (TFS), I see a couple of gaps. First, I have not able to make much headway with the reporting tools. Despite my complaints about TFS, it can produce some nice reports. Second, its not clear where if at all, Id keep track of purely internal tasks. Im talking about server maintenance, cleaning up source control, checking back on some code which you never quite felt right about. Theres no purpose in cluttering up an iteration backlog with these items, but if you dont track them, you lose them. Im not sure what a good answer for that is. One gap I thought Id see, which I dont, is more granular dev tasks. If Im implementing a story, Ill write out the steps and track my progress, but really, those steps arent useful to anybody but me. The only time Ive found that level of detail really useful is when my tasks are defined at too high a level anyway or when Im working with someone who needs more coaching and might not be able to finish a story in time without some scaffolding to get them going. You can learn more about Pivotal Tracker at: http://www.pivotaltracker.com/learnmore.   --- Relevant Links --- A good intro to stories: http://www.agilemodeling.com/artifacts/userStory.htmDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• A developer&rsquo;s WBS &ndash; 3 factors of 5

  - by johndoucette

  As a development manager, I have requested work breakdown structures (WBS) many times from the dev leads. Everyone has their own approach and why it takes sometimes days to get this simple list is often frustrating. Here is a simple way to get that elusive WBS done in 30 minutes and have 125 items in your list – well, 126. The WBS is made up of parent-child entities representing the overall outcome of the project. At the bottom of the hierarchical list should be the task item that a developer would perform in support of the branch in the list or WBS. Because I work with different dev leads on every project, I always ask the “what time value would you like to see at the lowest task in order to assign it to a developer and ensure it gets done within the timeframe”. I am particular to a task being 8 hours. Some like 8 to 24 hours. Stay away from tasks defaulting to 1 week. The task becomes way to vague and hard to manage completeness, especially on short budgets. As a developer, your focus is identifying the tasks you to accomplish in order to deliver the product. As a project manager, you will take the developer's WBS and add all the “other stuff” like quality testing, meetings, documentation, transition to maintenance, etc… Start your exercise with the name of the product you are delivering as a result of the project. You should be able to represent what you are building and deploying with one to three words. Example; XYZ Public Website Middleware BizTalk Application The reason you start with that single identifier is to always see the list as the product. It helps during each of the next three passes. Now, choose 5 tasks which in their entirety represent the product you will be delivering and add them to list under the product name you created earlier; Public Website     Security     Sites     Infrastructure     Publishing     Creative Continue this concept of seeing the list as the complete picture and decompose it one more level. You should have 25 items. Public Website     Security         Authentication         Login Control         Administration         DRM         Workflow     Sites         Masterpages         Page Layouts         Web Parts (RIA, Multimedia)         Content Types         Structures     Infrastructure         ...     Publishing         ...     Creative         ... And one more time for a total of 125 items. The top item makes the list 126. Public Website     Security         Authentication             Install (AD/ADAM/LDAP/SQL)             Configuration             Management             Web App Configuration             Implement Provider         Login Control             Login Form             Login/Logoff             pw change             pw recover/forgot             email verification         Administration             ...         DRM             ...         Workflow             ...     Sites         Masterpages         Page Layouts         Web Parts (RIA, Multimedia)         Content Types         Structures     Infrastructure         ...     Publishing         ...     Creative         ... The next step is to make sure the task at the bottom of every branch represents the “time value” you planned for the project. You can add more to the WBS and of course if you can’t find 5 items, 4 is fine. If a task can be done in a fraction of the time value you determined for the project, try to roll it up into a larger task. In the task actions (later when the iteration is being planned), decompose the details back to the simple tasks. Now, go estimate!

• Planning in the Cloud - For Real

  - by jmorourke

  One of the hottest topics at Oracle OpenWorld 2012 this week is “the cloud”.  Over the past few years, Oracle has made major investments in cloud-based applications, including some acquisitions, and now has over 100 applications available through Oracle Cloud services.  At OpenWorld this week, Oracle announced seven new offerings delivered via the Oracle Cloud services platform, one of which is the Oracle Planning and Budgeting Cloud Service.  Based on Oracle Hyperion Planning, this service is the first of Oracle’s EPM applications to be to be offered in the Cloud.    This solution is targeted to organizations that are struggling with spreadsheets or legacy planning and budgeting applications, want to deploy a world class solution for financial planning and budgeting, but are constrained by IT resources and capital budgets. With the Oracle Planning and Budgeting Cloud Service, organizations can fast track their way to world-class financial planning, budgeting and forecasting – at cloud speed, with no IT infrastructure investments and with minimal IT resources. Oracle Hyperion Planning is a market-leading budgeting, planning and forecasting application that is used by over 3,300 organizations worldwide.  Prior to this announcement, Oracle Hyperion Planning was only offered on a license and maintenance basis.  It could be deployed on-premise, or hosted through Oracle On-Demand or third party hosting partners.  With this announcement, Oracle’s market-leading Hyperion Planning application will be available as a Cloud Service and through subscription-based pricing. This lowers the cost of entry and deployment for new customers and provides a scalable environment to support future growth. With this announcement, Oracle is the first major vendor to offer one of its core EPM applications as a cloud-based service.  Other major vendors have recently announced cloud-based EPM solutions, but these are only BI dashboards delivered via a cloud platform.   With this announcement Oracle is providing a market-leading, world-class financial budgeting, planning and forecasting as a cloud service, with the following advantages: ·                     Subscription-based pricing ·                     Available standalone or as an extension to Oracle Fusion Financials Cloud Service ·                     Implementation services available from Oracle and the Oracle Partner Network ·                     High scalability and performance ·                     Integrated financial reporting and MS Office interface ·                     Seamless integration with Oracle and non-Oracle transactional applications ·                     Provides customers with more options for their planning and budgeting deployment vs. strictly on-premise or cloud-only solution providers. The OpenWorld announcement of Oracle Planning and Budgeting Cloud Service is a preview announcement, with controlled availability expected in calendar year 2012.  For more information, check out the links below: Press Release Web site If you have any questions or need additional information, please feel free to contact me at [email protected].

• My .NET Technology picks for 2011

  - by shiju

  My Technology predictions for 2011 Cloud computing and Mobile application development will be the hottest trends for 2011. I hope that Windows Azure will be very hot in year 2011 and lot of cloud computing adoption will be happen with Windows Azure on 2011. Web application scalability will be the big challenge for Architects in the next year and architecture approaches like CQRS will get some attention on next year. Architects will look on different options for web application scalability and adoption of NoSQL and Document databases will be more in the year 2011. The following are the my technology picks for .Net stack Windows Azure Windows Azure will be one of the hottest technologies of 2011. Adoption of Cloud and Windows Azure will get big attention on next year. The Windows Azure platform is a flexible cloud–computing platform that lets you focus on solving business problems and addressing customer needs. No need to invest upfront on expensive infrastructure. Pay only for what you use, scale up when you need capacity and pull it back when you don’t. We handle all the patches and maintenance — all in a secure environment with over 99.9% uptime. Silverlight 5 Silverlight is becoming a common technology for variety of development platforms. You can develop Silverlight applications for web, desktop and windows phone. The new Silverlight 5 beta will be available during the starting quarter of the next year with new capabilities and lot of new features. Silverlight 5 will be powerful development platform for both web-based business apps and rich media solutions. We can expect final version of Silverlight 5 on end of 2011. Windows Phone 7 Development Tools Mobile application development will be very hot in year 2011 and Windows Phone 7 will be one of the hottest technologies of next year. You can get introduction on Windows Phone 7 Development Tools from somasegar’s blog post and MSDN documentation available from here. EF Code First I am a big fan of Entity Framework’s Code First approach and hope that Code First approach will attract more people onto Entity Framework 4. EF Code First lets you focus on domain model which will enable Domain-Driven Development for applications. I hope that DDD fans will love the EF Code First approach. The Entity Framework 4 now supports three types of approaches and these will attract different types of developer audience. ASP.NET MVC 3 The ASP.NET MVC 3 will be the hottest technology of Microsoft web stack on the next year. ASP.NET developers will widely move to the ASP.NET MVC Framework from their WebForms development. The new Razor view engine is great and it will increase the adoption of ASP.NET MVC 3. Razor the will improve the productivity when working with ASP.NET MVC 3 Views. You can build great web applications using ASP.NET MVC 3 and jQuery with better maintainability, generation of clean HTML and even better performance. In my opinion, the best technology stack for web development is ASP.NET MVC 3 and Entity Framework 4 Code First as ORM. On the next year, you can expect more articles from my blog on ASP.NET MVC 3 and Entity Framework 4 Code First. RavenDB NoSQL and Document databases will get more attention on the coming year and RavenDB will be the most notable document database in the .NET stack. RavenDB is an Open Source (with a commercial option) document database for the .NET/Windows platform developed by Ayende Rahien. RavenDB is .NET focused document database which comes with a fully functional .NET client API and supports LINQ. I have written few articles on RavenDB and you can read it from here. Managed Extensibility Framework (MEF) Many people didn't realized the power of MEF. The MEF lets you create extensible applications and provides a great solution for the runtime extensibility problem. I hope that .NET developers will more adopt the MEF on the next year for their .NET applications. You can get an excellent introduction on MEF from Anoop Madhusudanan’s blog post MEF or Managed Extensibility Framework – Creating a Zoo and Animals

• PaaS, DBaaS and the Oracle Database Cloud Service

This variation is evident in one of the key misunderstandings about the Oracle Database Cloud Service. People could be forgiven for thinking that the Database Cloud Service was a Database-as-a-Service (DBaaS), but this is actually not true. The Database Cloud Service is a Platform-as-a-Service, which presents a different user and developer interface and has a different set of qualities. A good way to think about the difference between these two varieties of Cloud offerings is that you, the customer, have to deal with things at the level of the offering, but not for anything below it. In practice, this means that you do not have to deal with hardware or system software, including installation and maintenance, for DBaaS. You also do not have much control over configuration of these options. For PaaS, you don’t have to deal with hardware, system software, or database software – and also do not have control over these levels in the stack. So you cannot modify configuration parameters for the database with the Database Cloud Service – your interface is through SQL and PL/SQL, with Application Express, included in the Database Cloud Service, or through JDBC for Java apps running in the Java Cloud Service, or through RESTful Web Services. You will notice what is not mentioned there – SQL*Net. You cannot access your Oracle Database Cloud Service by changing an entry in the TNSNames file and using SQL*Net. So the effort involved in migrating an existing Oracle Database in your data center to the Database Cloud Service may be prohibitive. The good news is that Application Express and the RESTful Web Services wizard in the Database Cloud Service allow you to develop new applications very quickly, and, of course, the provisioning of the entire Database Cloud Service takes only minutes.

• Openmatics Revolutionizes Fleet Management with Standards-Based Vehicle Telematics Platform

  - by Michael Snow

  Openmatics s.r.o. was founded in 2010 as a subsidiary of ZF Friedrichshafen AG, a global player in driveline and chassis technology. Oracle Customer:  Openmatics s.r.o.Location:  Pilsen, Czech RepublicIndustry:  AutomotiveEmployees:  70 Its goal was to develop and operate a flexible, open telematics platform for automotive applications, which is independent from vehicle and component suppliers—recognizing that the fragmented telematics market was not meeting today’s fleet management needs. Openmatics provides a rich product portfolio, and customers can extend the platform, as required, to meet their needs. Partners and third-parties can develop their own applications using the Openmatics’ software development kit and can sell them via the Openmatics app shop.ZF Friedrichshafen AG is a global player in driveline and chassis technology. With 121 production companies and 650 service partners in 26 countries, ZF is among the top 10 largest automotive suppliers worldwide. Founded in 1915 to develop and produce transmissions for airships and vehicles, the group’s product offerings now include transmissions and steering systems as well as chassis components and complete axle systems and modules.  A word from Openmatics s.r.o.  “Oracle WebCenter Portal, together with the underlying Oracle Application Development Framework, provided the fundamental infrastructure for the Openmatics platform. Fleet managers can now reduce fuel consumption and operating costs, and more efficiently manage vehicle usage, maintenance, and safety. The standards-based platform allows third-party suppliers to deploy their own vehicle telematics services as Openmatics apps and creates a de facto standard for the automotive industry, independent from a single manufacturer or service provider.” – Gero Strobel, Head of Development, Openmatics s.r.o. Challenges Create an industry standard for vehicle telematics by establishing a customizable platform that enables access to telematics information, such as current and past fuel consumption, through a web browser to better meet automotive market and customer needs Reduce fleet-management costs by eliminating the need to invest in isolated telematics hardware and software solutions per vehicle brand and vehicle component manufacturer Establish an open platform where third-party providers—such as original equipment manufacturers (OEM), insurers, fleet operators, and individual developers—can deploy their own vehicle telematics services Allow users to purchase targeted telematics services as single apps to reduce costs and ensure rapid growth of telematics services available on the platform Enable users to configure their telematics apps with ease to make sure the platform meets individual fleet management requirements, such as analyzing past and current fuel consumption of a truck fleet Solutions Deployed Oracle WebCenter Portal as a foundation for Openmatics, a standards-based automotive telematics platform that provides next-generation fleet management with unified digital communication from and to vehicles on the move Used Oracle Application Development Framework as the development framework for Oracle WebCenter Portal’s components and services, providing developers with ready-to-use software development kits with application programming interfaces, design templates, and visual tools that accelerated time to market Used Oracle Enterprise Pack for Eclipse to simplify telematics application development in Java Enabled fleet monitoring by recording vehicle data—such as fuel consumption information—through onboard units, delivering the information to Oracle Database, and making it accessible through a customizable app portfolio on any web browser Stored vehicle telematics data—sent as encrypted information—in Oracle Database, ensuring data integrity and immediate availability for the platform’s telematics applications Enabled a wide range of telematics services suppliers, from vehicle component manufacturers to fleet application developers, to offer vehicle telematics services on the Openmatics platform, ensuring platform independence from OEMs Provided Openmatics customers with the means to individually select the automotive telematics services that are relevant to their business requirements, eliminating the need to pay for superfluous information and reducing fleet management costs Oracle Products & Services Oracle Application Development Framework Oracle WebCenter Portal Oracle SOA Suite Oracle Enterprise Pack for Eclipse Oracle Database Oracle Consulting &amp;amp;amp;amp;amp;amp;amp;&amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;gt;amp;&amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;gt;lt;p&amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;lt;/p&amp;amp;amp;amp;amp;amp;amp;amp;gt;

• Columnstore Case Study #1: MSIT SONAR Aggregations

  - by aspiringgeek

  Preamble This is the first in a series of posts documenting big wins encountered using columnstore indexes in SQL Server 2012 & 2014.  Many of these can be found in this deck along with details such as internals, best practices, caveats, etc.  The purpose of sharing the case studies in this context is to provide an easy-to-consume quick-reference alternative. Why Columnstore? If we’re looking for a subset of columns from one or a few rows, given the right indexes, SQL Server can do a superlative job of providing an answer. If we’re asking a question which by design needs to hit lots of rows—DW, reporting, aggregations, grouping, scans, etc., SQL Server has never had a good mechanism—until columnstore. Columnstore indexes were introduced in SQL Server 2012. However, they're still largely unknown. Some adoption blockers existed; yet columnstore was nonetheless a game changer for many apps.  In SQL Server 2014, potential blockers have been largely removed & they're going to profoundly change the way we interact with our data.  The purpose of this series is to share the performance benefits of columnstore & documenting columnstore is a compelling reason to upgrade to SQL Server 2014. App: MSIT SONAR Aggregations At MSIT, performance & configuration data is captured by SCOM. We archive much of the data in a partitioned data warehouse table in SQL Server 2012 for reporting via an application called SONAR.  By definition, this is a primary use case for columnstore—report queries requiring aggregation over large numbers of rows.  New data is refreshed each night by an automated table partitioning mechanism—a best practices scenario for columnstore. The Win Compared to performance using classic indexing which resulted in the expected query plan selection including partition elimination vs. SQL Server 2012 nonclustered columnstore, query performance increased significantly.  Logical reads were reduced by over a factor of 50; both CPU & duration improved by factors of 20 or more.  Other than creating the columnstore index, no special modifications or tweaks to the app or databases schema were necessary to achieve the performance improvements.  Existing nonclustered indexes were rendered superfluous & were deleted, thus mitigating maintenance challenges such as defragging as well as conserving disk capacity. Details The table provides the raw data & summarizes the performance deltas. Logical Reads (8K pages) CPU (ms) Durn (ms) Columnstore 160,323 20,360 9,786 Conventional Table & Indexes 9,053,423 549,608 193,903 ? x56 x27 x20 The charts provide additional perspective of this data.  "Conventional vs. Columnstore Metrics" document the raw data.  Note on this linear display the magnitude of the conventional index performance vs. columnstore.  The “Metrics (?)” chart expresses these values as a ratio. Summary For DW, reports, & other BI workloads, columnstore often provides significant performance enhancements relative to conventional indexing.  I have documented here, the first in a series of reports on columnstore implementations, results from an initial implementation at MSIT in which logical reads were reduced by over a factor of 50; both CPU & duration improved by factors of 20 or more.  Subsequent features in this series document performance enhancements that are even more significant.

When the focus is on speed, it can be easy to continue to use old style, point-to-point custom scripts that grow organically to the point where they are unmanageable and too costly to maintain. As data volumes, data sources, and end users grow, uncoordinated data integration efforts create significant inefficiencies for both IT and business users. In addition to losing IT productivity due to maintaining spaghetti architecture, data integrity becomes a concern as well. Errors caused by inconsistent, data and manual data entry can prove very costly for companies and disrupt business activities. Many industry leaders recognize now that data should be moved in an automated and reliable manner across all platforms to have one version of the truth. By simplifying their data integration architecture and standardizing on a centralized approach, IT teams now accelerate time to market. Especially, using a centralized, shared-service approach brings agility, increases IT productivity, and frees up resources for innovation.

• MySQL Enterprise Backup 3.8.2 has been released!

  - by Hema Sridharan

  MySQL Enterprise Backup v3.8.2, a maintenance release of online MySQL backup tool, is now available for download from My Oracle Support  (MOS) website as our latest GA release.  It will also be available via the Oracle Software Delivery Cloud in approximately 1-2 weeks. A brief summary of the changes in MySQL Enterprise Backup version 3.8.2 is given below.   A. Functionality Added or Changed:  MySQL Enterprise Backup has a new --on-disk-full command line option. mysqlbackup could hang when the disk became full, rather than detecting the low space condition. mysqlbackup now monitors disk space when running backup commands, and users can now specify the action to take at a disk-full condition with the --on-disk-full option. For more details, refer this page MySQL Enterprise Backup has a new progress report feature, which periodically outputs short progress indicators on its  operations to user-selected destinations (for example, stdout, stderr, a file, or other choices). For more details on progress report options, refer here   B. Bugs Fixed: When --innodb-file-per-table=ON, if a table was renamed and backup-to-image was in progress, apply-log would fail when being run on the backup. (Bug #16903973)   MySQL Server failed to start after a backup was restored if  there had been online DDL transactions on partitioned tables during the time of backup. (Bug #16924499)   apply-log failed if ALTER TABLE ... REORGANIZE PARTITION was applied to partitioned InnoDB tables during backup. (Bug #16721824, Bug #16903951)  apply-incremental-backup might fail with an assertion error if  the InnoDB tables being backed up were created in Barracuda format and with their KEY_BLOCK_SIZE  values  different from the innodb_page_size . This fix ensures that different KEY_BLOCK_SIZE  values are handled properly during incremental backup and apply-incremental-backup operations.  If a table was renamed following a full backup, a subsequent incremental backup could copy the .frm file with the new name, but not the associated .ibd file with the new name. After a  restore, the InnoDB data dictionary could be in an  inconsistent state. This issue primarily occurred if the table  was not changed between the full backup and the subsequent  incremental backup. Bug #16262690)  After a full backup, if a table was renamed and modified,  apply-incremental-backup would crash when run on the backup directory. (Bug #16262609) The value of the binary log position in backup_variables.txt  could be different from the output displayed during the   backup-and-apply-log operation. (This issue did not occur if  the backup and apply-log steps were done separately.) (Bug  #16195529) When using the --only-innodb-with-frm option, MySQL Enterprise Backup tried to create temporary files at unintended locations in the file system, which might cause a failure when, for example, the user had no write privilege for those locations.   This fix makes sure the paths for the temporary files are  correct. (Bug #14787324)  A backup process might hang when it ran into an LSN mismatch between a data file  and the redo log. This fix makes sure the process does not hang and it displays an error message showing the  name of the problematic data file (Bug #14791645) Please post your questions / comments about Backup in forums. Thanks, MEB Team

• Spotlight on Oracle Social Relationship Management. Social Enable Your Enterprise with Oracle SRM.

  - by Pat Ma

  Facebook is now the most popular site on the Internet. People are tweeting more than they send email. Because there are so many people on social media, companies and brands want to be there too. They want to be able to listen to social chatter, engage with customers on social, create great-looking Facebook pages, and roll out social-collaborative work environments within their organization. This is where Oracle Social Relationship Management (SRM) comes in. Oracle SRM is a product that allows companies to manage their presence with prospects and customers on social channels. Let's talk about two popular use cases with Oracle SRM. Easy Publishing - Companies now have an average of 178 social media accounts - with every product or geography or employee group creating their own social media channel. For example, if you work at an international hotel chain with every single hotel creating their own Facebook page for their location, that chain can have well over 1,000 social media accounts. Managing these channels is a mess - with logging in and out of every account, making sure that all accounts are on brand, and preventing rogue posts from destroying the brand. This is where Oracle SRM comes in. With Oracle Social Relationship Management, you can log into one window and post messages to all 1,000+ social channels at once. You can set up approval flows and have each account generate their own content but that content must be approved before publishing. The benefits of this are easy social media publishing, brand consistency across all channels, and protection of your brand from inappropriate posts. Monitoring and Listening - People are writing and talking about your company right now on social media. 75% of social media users have written a negative post about a brand after a poor customer service experience. Think about all the negative posts you see in your Facebook news feed about delayed flights or being on hold for 45 minutes. There is so much social chatter going on around your brand that it's almost impossible to keep up or comprehend what's going on. That's where Oracle SRM comes in. With Social Relationship Management, a company can monitor and listen to what people are saying about them on social channels. They can drill down into individual posts or get a high level view of trends and mentions. The benefits of this are comprehending what's being said about your brand and its competitors, understanding customers and their intent, and responding to negative posts before they become a PR crisis. Oracle SRM is part of Oracle Cloud. The benefits of cloud deployment for customers are faster deployments, less maintenance, and lower cost of ownership versus on-premise deployments. Oracle SRM also fits into Oracle's vision to social enable your enterprise. With Oracle SRM, social media is not just a marketing channel. Social media is also mechanism for sales, customer support, recruiting, and employee collaboration. For more information about how Oracle SRM can social enable your enterprise, please visit oracle.com/social. For more information about Oracle Cloud, please visit cloud.oracle.com.

• Path Not Found error when opening VB6 project from a shared folder on Virtual PC 2007 (XP sp3)

  - by law1185

  I currently work on a small software team that primarily maintains legacy software. I am trying to set up a VirtualPC that we can use to do this maintenance. Specifically, I would like to be able to debug and run VB6 web apps from a folder on the host pc. My constraints are as follows: The VirtualPC will not be registered on the domain. The server that hosts our Subversion repository does not run the subversion service so the only way to interact with the repository is through "file:\\", which requires domain authentication. It is not possible to debug/run VB6 web apps that are located on mapped network drives, because IIS requires that the VirtualPC be on the same domain as the network drive I would like to avoid having to copy the folder from the host pc to the VirtualPC and then copying it back in order to have the latest revision from Subversion So, I am trying to use VirtualPC's shared folder feature to share the host machine's Subversion directory and open the project in VB6 on the VirtualPC. Problem is that Visual Basic throws the error: "Path not found: '\\C:\\Subversion\Path\Project.vbp'" when I try to open it. Folder C:\Subversion on the host machine is mapped to G: on the VirtualPC. If anyone can help me resolve this error or find some other way to accomplish this, I would be deeply grateful. Oh, both host and virtual OS is Windows XP sp3. Using VB 6.0, IIS v5.1. I can manipulate files in the shared directory freely from the VirtualPC ie. copy, paste, delete, etc. Edit: Link to screenshot: http://img190.imageshack.us/img190/5439/vpcscreen.png

• TF203015 The Item $/path/file has an incompatible pending change. While trying to unshelve.

  - by drachenstern

  I'm using Visual Studio 2010 Pro against Team Server 2010 and I had my project opened (apparently) as a solution from the repo, but I should've opened it as "web site". I found this out during compile, so I went to shelve my new changes and deleted the project from my local disk, then opened the project again from source (this time as web site) and now I can't unshelve my files. Is there any way to work around this? Did I blow something up? Do I need to do maintenance at the server? I found this question on SO #2332685 but I don't know what cache files he's talking about (I'm on XP :\ ) EDIT: Found this link after posting the question, sorry for the delay in researching, still didn't fix my problem Of course I can't find an error code for TF203015 anywhere, so no resolution either (hence my inclusion of the number in the title, yeah?) EDIT: I should probably mention that these files were never checked in in the first place. Does that matter? Can you shelve an unchecked item? Is that what I did wrong? EDIT: WHAP - FOUND IT!!! Use "Undo" on the items that don't exist because they show up in pending changes as checkins.

• Selectively suppress XML Code Comments in C#?

  - by Mike Post

  We deliver a number of assemblies to external customers, but not all of the public APIs are officially supported. For example, due to less than optimal design choices sometimes a type must be publicly exposed from an assembly for the rest of our code to work, but we don't want customers to use that type. One part of communicating the lack of support is not provide any intellisense in the form of XML comments. Is there a way to selectively suppress XML comments? I'm looking for something other than ignoring warning 1591 since it's a long term maintenance issue. Example: I have an assembly with public classes A and B. A is officially supported and should have XML documentation. B is not intended for external use and should not be documented. I could turn on XML documentation and then suppress warning 1591. But when I later add the officially supported class C, I want the compiler to tell me that I've screwed up and failed to add the XML documentation. This wouldn't occur if I had suppressed 1591 at the project level. I suppose I could #pragma across entire classes, but it seems like there should be a better way to do this.

• XtraGrid Suite - is there a way to add a button or hyperlink to a cell?

  - by calico-cat

  I'm working with the XtraGrid Suite made by DevExpress. I can't find any sort of functionality to do this, but I'm curious if you can add a button or hyperlink to a grid cell. Context: I've got an Events list. Each Event has a Time, Start/End, and a Category (Utility and Maintenance). There can be Start events and Stop events. Having done my analysis of the problem, I've decided that having a StartTime and EndTime for each event would not work. So if an event starts, I'd record the current time to the Event object, and set it as a 'Start' event. I'd like to add a "Stop" button/hyperlink to a cell in that row. If the user wishes to log an Ends event, the event type, etc would be copied to a new Event with the type 'Stop' and the button would disappear. I hope this makes sense. EDIT: Aaronaught's answer is actually better than what I was originally asking (a button) so I've updated the question. That way, anyone looking for putting a hyperlink in a cell can benefit from his example : )

• Default Transaction Timeout

  - by MattH

  I used to set Transaction timeouts by using TransactionOptions.Timeout, but have decided for ease of maintenance to use the config approach: <system.transactions> <defaultSettings timeout="00:01:00" /> </system.transactions> Of course, after putting this in, I wanted to test it was working, so reduced the timeout to 5 seconds, then ran a test that lasted longer than this - but the transaction does not appear to abort! If I adjust the test to set TransactionOptions.Timeout to 5 seconds, the test works as expected After Investigating I think the problem appears to relate to TransactionOptions.Timeout, even though I'm no longer using it. I still need to use TransactionOptions so I can set IsolationLevel, but I no longer set the Timeout value, if I look at this object after I create it, the timeout value is 00:00:00, which equates to infinity. Does this mean my value set in the config file is being ignored? To summarise: Is it impossible to mix the config setting, and use of TransactionOptions If not, is there any way to extract the config setting at runtime, and use this to set the Timeout property [Edit] OR Set the default isolation-level without using TransactionOptions

• Unit testing Monorail's RenderText method

  - by MikeWyatt

  I'm doing some maintenance on an older web application written in Monorail v1.0.3. I want to unit test an action that uses RenderText(). How do I extract the content in my test? Reading from controller.Response.OutputStream doesn't work, since the response stream is either not setup properly in PrepareController(), or is closed in RenderText(). Example Action public DeleteFoo( int id ) { var success= false; var foo = Service.Get<Foo>( id ); if( foo != null && CurrentUser.IsInRole( "CanDeleteFoo" ) ) { Service.Delete<Foo>( id ); success = true; } CancelView(); RenderText( "{ success: " + success + " }" ); } Example Test (using Moq) [Test] public void DeleteFoo() { var controller = new FooController (); PrepareController ( controller ); var foo = new Foo { Id = 123 }; var mockService = new Mock < Service > (); mockService.Setup ( s => s.Get<Foo> ( foo.Id ) ).Returns ( foo ); controller.Service = mockService.Object; controller.DeleteTicket ( foo.Id ); mockService.Verify ( s => s.Delete<Foo> ( foo.Id ) ); Assert.AreEqual ( "{success:true}", GetResponse ( Response ) ); } // response.OutputStream.Seek throws an "System.ObjectDisposedException: Cannot access a closed Stream." exception private static string GetResponse( IResponse response ) { response.OutputStream.Seek ( 0, SeekOrigin.Begin ); var buffer = new byte[response.OutputStream.Length]; response.OutputStream.Read ( buffer, 0, buffer.Length ); return Encoding.ASCII.GetString ( buffer ); }

• [Linq to SQL] Multiple foreign keys to the same table

  - by cdonner

  I have a reference table with all sorts of controlled value lookup data for gender, address type, contact type, etc. Many tables have multiple foreign keys to this reference table I also have many-to-many association tables that have two foreign keys to the same table. Unfortunately, when these tables are pulled into a Linq model and the DBML is generated, SQLMetal does not look at the names of the foreign key columns, or the names of the constraints, but only at the target table. So I end up with members called Reference1, Reference2, ... not very maintenance-friendly. Example: <Association Name="tb_reference_tb_account" Member="tb_reference" <====== ThisKey="shipping_preference_type_id" OtherKey="id" Type="tb_reference" IsForeignKey="true" /> <Association Name="tb_reference_tb_account1" Member="tb_reference1" <====== ThisKey="status_type_id" OtherKey="id" Type="tb_reference" IsForeignKey="true" /> I can go into the DBML and manually change the member names, of course, but this would mean I can no longer round-trip my database schema. This is not an option at the current stage of the model, which is still evolving. Splitting the reference table into n individual tables is also not desirable. I can probably write a script that runs against the XML after each generation and replaces the member name with something derived from ThisKey (since I adhere to a naming convention for these types of keys). Has anybody found a better solution to this problem?

• What are common anti-patterns when using VBA

  - by Ahmad

  I have being coding a lot in VBA lately (maintenance and new code), specifically with regards to Excel automation etc. = macros. Typically most of this has revolved around copy/paste, send some emails, import some files etc. but eventually just ends up as a Big ball of mud As a person who values clean code, I find it very difficult to produce 'decent' code when using VBA. I think that in most cases, this is a direct result of the macro-recorder. Very helpful to get you started, but most times, there are one too many lines of code that achieve the end result. Edit: The code from the macro-recorder is used as a base to get started, but is not used in its entirety in the end result I have already created a common addin that has my commonly used subroutines and some utility classes in an early attempt to enforce some DRYness - so this I think is a step in the right direction. But I feel as if it's a constant square peg, round hole situation. The wiki has an extensive list of common anti-patterns and what scared me the most was how many I have implemented in one way or another. The question Now considering, that my mindset is OO design, what some common anti-patterns and the possible solutions when designing a solution (think of this - how would designing a solution using Excel and VBA be different from say a .net/java/php/.../ etc solution) ; and when doing common tasks like copying data, emailing, data importing, file operations... etc An anti-pattern as defined by Wikipedia is: In software engineering, an anti-pattern (or antipattern) is a pattern that may be commonly used but is ineffective and/or counterproductive in practice

• Java EE suitablity for a social network using Cassandra datastore ??

  - by Marcos

  We are in the process of making some important technology decisions for a social networking application. We're planning to have Cassandra(a NoSQL database to support efficient data storage). We would be using Hector(a Java client) to interact with Cassandra. 1.) Would Java EE be a good choice over PHP for a social networking application in terms of performance, scalabilty & complexities? 2.) Another possible implementation strategy, Is it suitable to have backend alone in Java and rest in PHP? 3.) What differences(as compared to PHP) it makes in terms of costs at various stages of application development, deployment and maintenance ? 4.) What are the things to keep in mind as we move along with Java development& deployment(as we are relatively new to the Java background) ? 5.) If you could list some major production deployments of similar type(social network) applications in Java. Thank you!

• nHibernate strategies in a web farm

  - by Pete Nelson

  Our current project at work is a new MVC web site that will use a WCF service primarily to access a 3rd party billing system via a web service as well as a small SQL database for user personalization. The WCF service uses nHibernate for the SQL database. We'd like to implement some sort of web farm for load balancing as well as failover and maintenance. I'm trying to decide the best way to handle nHibernate's caching and database concurrency if there are multiple WCF services running. Some scenarios I've been thinking about... 1) Multiple IIS servers, one WCF server. With this setup, the WCF server would be a single point of failure, but there would be no issues with nHibernate caching or database concurrency. 2) Multiple IIS servers, each with it's own WCF service. This removes a single point of failure, but now nHibernate on one machine would not know about database changes done by another machine. Some solutions to number 2 would be to use an IStatelessSession so we're not doing any caching and nHibernate is always fetching directly from the database. This might be the most feasible as our personalization database has very few objects in it. I'm also considering a 2nd-level cache such as memcached or Velocity, but it may be overkill for this system. I'm putting this out there to see if anyone has experience doing this sort of architecture and to get some ideas for a solution. Thanks!

• To Ajax or Not to Ajax a listing page

  - by kaivalya

  Here i am talking about product listing pages where there are multiple filters that filter the list of products appearing on the page like product types, categories price range etc. I have done such pages using both ajax and no ajax way in the past. What I like about using ajax in such page is that, when filters are selected I only update the section that contains the product list. There is no need to refresh the whole page which could end up re-loading the images on top bar, banners etc and slow down the user performance. Ajax way in my opinion becomes more compact and responsive from user experience. Down side for ajax route for me is; since filter states are not maintained in the URL I end up maintaining them on the server. This becomes complicated if I want to handle multi window scenarios and it is also costly to maintain such state on server memory for each session. Not using ajax and simply keeping all filter values on url and refreshing the page is quite simple but the luxury of refreshing only the pane that really needs to be refreshed is lost. Lately I am seeing a lot of large scale e-commerce sites that are using non-ajax approach on their listing pages and this is making me question one more time if it might be more efficient to build non-ajax listing make due to the long term maintenance ease and sacrifice a little bit from user experience. I am about to start implementing a new listing page for a product which I have the flexibility to go either way and I would appreciate your inputs.
