  • WebLogic history an interview with Laurie Pitman by Qualogy

    - by JuergenKress
    All those years that I am working with WebLogic, the BEA and Oracle era are the most well known about WebLogic evolving into a worldwide Enterprise platform for Java applications, being used by multinationals around the globe. But how did it all begin? Besides from the spare info you find on some Internet pages, I was eager to hear it in person from one of the founders of WebLogic back in 1995, before the BEA era, Laurie Pitman. Four young people, Carl Resnikoff, Paul Ambrose, Bob Pasker, and Laurie Pitman, became friends and colleagues about the time of the first release of Java in 1995. Between the four of them, they had an MA in American history, an MA in piano, an MS in library systems, a BS in chemistry, and a BS in computer science. They had come together kind of serendipitously, interested in building some web tools exclusively in Java for the emerging Internet web application market. They found many things to like about each other, some overlap in our interests, but also a lot of well-placed differences which made a partnership particularly interesting. They made it formal in January 1996 by incorporating. Read the complete article here.

  • Methodology behind fetching large XML data sets in pieces

    - by Jerry Dodge
    I am working on an HTTP Server in Delphi which simply sends back a custom XML dataset. I am not following any type of standard formatting, such as SOAP. I have the system working seamlessly, except one small flaw: When I have a very large dataset to send back to the client, it might take up to 2 minutes for all the data to be transferred. The HTTP Server I'm building is essentially an XML Data based API around a database, implementing the common business rule - therefore, the requests are specific to the data behind the system. When, for example, I fetch a large set of product data, I would like to break this down and send it back piece by piece. However, a single HTTP request calls for a single response. I can't necessarily keep feeding the client with multiple different XML packets unless the client explicitly requests it. I don't have any session management, but rather an API Key. I know if I had sessions, I could keep-alive a dataset temporarily for a client, and they could request bits and pieces of it. However, without session management, I would have to execute the SQL query multiple times (for each chunk of data), and in the mean-time, if that data changes, the "pages" might get messed up, therefore causing items to show on the wrong pages, after navigating to a different page. So how is this commonly handled? What's the methodology behind breaking down a large XML dataset into chunks to save the load?

  • make-like build tools for data?

    - by miku
    Make is a standard tools for building software. But make decides whether a target needs to be regenerated by comparing file modification times. Are there any proven, preferably small tools that handle builds not for software but for data? Something that regenerates targets not only on mod times but on certain other properties (e.g. completeness). (Or alternatively some paper that describes such a tool.) As illustration: I'd like to automate the following process: get data (e.g. a tarball) from some regularly updated source copy somewhere if it's not there (based e.g. on some filename-scheme) convert the files to different format (but only if there aren't successfully converted ones there - e.g. from a previous attempt - custom comparison routine) for each file find a certain data element and fetch some additional file from say an URL, but only if that hasn't been downloaded yet (decide on existence of file and file "freshness") finally compute something (e.g. word count for something identifiable and store it in the database, but only if the DB does not have an entry for that exact ID yet) Observations: there are different stages each stage is usually simple to compute or implement in isolation each stage may be simple, but the data volume may be large each stage may produce a few errors each stage may have different signals, on when (re)processing is needed Requirements: builds should be interruptable and idempotent (== robust) when interrupted, already processed objects should be reused to speedup the next run data paths should be easy to adjust (simple syntax, nothing new to learn, internal dsl would be ok) some form of dependency graph, that describes the process would be nice for later visualizations should leverage existing programs, if possible I've done some research on make alternatives like rake and have worked a lot with ant and maven in the past. All these tools naturally focus on code and software build, not on data builds. A system we have in place now for a task similar to the above is pretty much just shell scripts, which are compact (and are a ok glue for a variety of other programs written in other languages), so I wonder if worse is better?

  • 4 Top Tips from the Exceptional DBA Award judges

    - by Rebecca Amos
    There's still time to celebrate your achievements as a DBA – or those of a DBA you know – by submitting a nomination for the Exceptional DBA Awards 2011. To help you get started, here are some top tips from the judges on what they're looking for from this year's winner [hint: it's very likely you're already exceptional!]: "An Exceptional DBA must be able to communicate effectively and clearly with both technical people and the client." Steve Jones. "Exceptional DBAs are like police officers: we're here to serve and protect. Both serving and protecting are vital parts of the job, and we can't just focus on one." Brent Ozar "DBA work can be routine. Exceptional DBAs are enthusiastic about their work and are rarely bored, as there is always something new to learn and master." Brad McGehee. "Remember that cost is an important factor for your company. The ability to save your company money with a different technical solution will make you an Exceptional DBA, and can make you exceptionally well liked." Rodney Landrum. So whether you've brought a team together for a project, taken steps to protect the security of your servers, or learnt a new topic to understand an element of your job better, it's likely you’re already taking the steps that make you the Exceptional DBA the judges are looking for.

  • SharePoint Apps and Windows Azure

    - by ScottGu
    Last Monday I had an opportunity to present as part of the keynote of this year’s SharePoint Conference.  My segment of the keynote covered the new SharePoint Cloud App Model we are introducing as part of the upcoming SharePoint 2013 and Office 365 releases.  This new app model for SharePoint is additive to the full trust solutions developers write today, and is built around three core tenants: Simplifying the development model and making it consistent between the on-premises version of SharePoint and SharePoint Online provided with Office 365. Making the execution model loosely coupled – and enabling developers to build apps and write code that can run outside of the core SharePoint service. This makes it easy to deploy SharePoint apps using Windows Azure, and avoid having to worry about breaking SharePoint and the apps within it when something is upgraded.  This new loosely coupled model also enables developers to write SharePoint applications that can leverage the full capabilities of the .NET Framework – including ASP.NET Web Forms 4.5, ASP.NET MVC 4, ASP.NET Web API, EF 5, Async, and more. Implementing this loosely coupled model using standard web protocols – like OAuth, JSON, and REST APIs – that enable developers to re-use skills and tools, and easily integrate SharePoint with Web and Mobile application architectures. A video of my talk + demos is now available to watch online: In the talk I walked through building an app from scratch – it showed off how easy it is to build solutions using new SharePoint application, and highlighted a web + workflow + mobile scenario that integrates SharePoint with code hosted on Windows Azure (all built using Visual Studio 2012 and ASP.NET 4.5 – including MVC and Web API). The new SharePoint Cloud App Model is something that I think is pretty exciting, and it is going to make it a lot easier to build SharePoint apps using the full power of both Windows Azure and the .NET Framework.  Using Windows Azure to easily extend SaaS based solutions like Office 365 is also a really natural fit and one that is going to offer a bunch of great developer opportunities.  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

  • DEEP DIVE MVVM at #MIX11

    - by Laurent Bugnion
    The public (you!) has spoken, and “Deep Dive MVVM” was selected (along with 11 other open call talks) out of 217 proposals. There were 17’000 votes! These are pretty amazing numbers, and believe me when I tell you that I still didn’t completely realize what just happened! I want to really underline the outstanding quality of many of the talks that were proposed. I decided not to reveal my votes, because I just know too many of the candidates and I had only 10 votes but let’s just say that some of my favorites were picked, and some were not, and I really wish that I can see them all either at MIX or in another conference. I already started putting down ideas for the talk (not too many, because I didn’t want to jinx it) and it should be a really great session. We will, as the title shows, dive deep into the subtleties of MVVM, and explore some techniques that allow to overcome some of the hurdles presented by this pattern. This session will be shaped by many emails that I received over the past year, since “Understanding the MVVM pattern” was presented, and offered, for many, a first look into Model-View-ViewModel. So now’s the chance, comment and let me know what topics you would like to discuss. If you had not done so before, go ahead and watch last year’s session, it will be a great preparation. Let’s talk real life development, let’s explore the problems and find solutions. I already have a nice collection of emails asking questions around MVVM and my goal is to answer as many as I can. Leave a comment and I will do my best to answer these as well. The date/time was not announced yet, so watch this space for details. I am really looking forward to seeing many of you in Las Vegas, and for those who cannot make it, don’t worry, all the sessions will be published in video by the amazing MIX team a few hours after the session actually takes place. Thanks for your confidence and in the meantime, Happy Coding! Laurent Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

It would eventually start working after I messed around with the audio settings, but it happened every restart. I eventually switched to SMPlayer, but now I need some of the features that VLC offers, but I still can't use VLC. At this point, the audio can not be heard at all, and the method I used before, messing around with the audio settings, isn't getting me anywhere.

  • MSCC: Purpose and benefits of Version Control Systems (VCS)

    You're working in IT and not using any kind of version control system? Sorry, then you're doing something wrong! RSVP for MSCC meetup of June This month's meetup will be an introduction into the mechanics of version control systems (VCS) like git, Mercurial, TFS, and others in general. VCS are not optional but compulsory in any area of IT. Whether you're developing source code for the next buzz app, writing SQL scripts for your database, or automating your administrative tasks with shell scripts it's better to have a "time machine" in order to keep multiple version, stay organised and leverage the power of differences. git - a modern approach to VCS - Nayar Nayar is going to give us a brief overview of the basic principles of working with git. Which are the necessary steps to get started and which are the usual commands in order to get the most out of git. Visual Studio Online (VSO) - Jochen Are you mainly rooted on the Windows platform and looking for a good alternative to Team Foundation Services (TFS), then VSO might give you hand at achieving this. Similar to git VSO is an open infrastructure but plays very well together with the Microsoft Azure cloud infrastructure. Recent and upcoming events in Mauritius Let's have a chat about recent events like WebCup 2014 or Emtel Knowledge Series and have a head start on upcoming events like Code Challenge, and others to come. Networking and general discussions Of course, there will be plenty of time to chat and exchange with other like-minded craftsmen. Bring your topics and discuss various issues with other professionals. Share your experience and use the ability to learn from others. Looking forward to meet soon.

  • How to use semantic markup and Google Places to assist in local search SEO?

    - by ElHaix
    In this article, adding additional localized markup is supposed to help your site's SEO. ie. <div itemscope itemtype="http://data-vocabulary.org/Organization"> <span itemprop="name">Search Engine People</span> <span itemprop="address" itemscope itemtype="http://data-vocabulary.org/Address"> <span itemprop="street-address">100 Westney Road South Unit 200, Building E</span> <span itemprop="locality">Ajax</span>, <span itemprop="region">ON</span> <span itemprop="country-name">Canada</span> <span itemprop="postal-code">L1S 7H3</span> </div> What about a site that contains valid localized results, where the actual business location is not relevant. For example, a site with valid local results from San Francisco, CA and Phoenix, AZ. Should these tags be added to the localized results, and has anyone got any experience with how much adding these tags have improved results? In terms of Google Places, however, they seem to ask for the business' actual physical location. Is there a way to use Google Places in the aforementioned example to assist in SEO?

  • When Your Boss Doesn't Want you to Succeed

    - by Phil Factor
    You're working hard to get an application finished. You are programming long into the evenings sometimes, and eating sandwiches at your desk instead of taking a lunch break. Then one day you glance up at the IT manager, serene in his mysterious round of meetings, and think 'Does he actually care whether this project succeeds or not?'. The question may seem absurd. Of course the project must succeed. The truth, as always, is often far more complex. Your manager may even be doing his best to make sure you don't succeed. Why? There have always been rich pickings for the unscrupulous in IT.  In extreme cases, where administrators struggle with scarcely-comprehended technical issues, huge sums of money can be lost and gained without any perceptible results. In a very few cases can fraud be proven: most of the time, the intricacies of the 'game' are such that one can do little more than harbor suspicion.  Where does over-enthusiastic salesmanship end and fraud begin? The Business of Information Technology provides rich opportunities for White-collar crime. The poor developer has his, or her, hands full with the task of wrestling with the sheer complexity of building an application. He, or she, has no time for following the complexities of the chicanery of the management that is directing affairs.  Most likely, the developers wouldn't even suspect that their company management had ulterior motives. I'll illustrate what I mean with an entirely fictional, hypothetical, example. The Opportunist and the Aged Charities often do good, unexciting work that is funded by the income from a bequest that dates back maybe hundreds of years.  In our example, it isn't exciting work, for it involves the welfare of elderly people who have fallen on hard times.  Volunteers visit, giving a smile and a chat, and check that they are all right, but are able to spend a little money on their discretion to ameliorate any pressing needs for these old folk.  The money is made to work very hard and the charity averts a great deal of suffering and eases the burden on the state. Daisy hears the garden gate creak as Mrs Rainer comes up the path. She looks forward to her twice-weekly visit from the nice lady from the trust. She always asked ‘is everything all right, Love’. Cheeky but nice. She likes her cheery manner. She seems interested in hearing her memories, and talking about her far-away family. She helps her with those chores in the house that she couldn’t manage and once even paid to fill the back-shed with coke, the other year. Nice, Mrs. Rainer is, she thought as she goes to open the door. The trustees are getting on in years themselves, and worry about the long-term future of the charity: is it relevant to modern society? Is it likely to attract a new generation of workers to take it on. They are instantly attracted by the arrival to the board of a smartly dressed University lecturer with the ear of the present Government. Alain 'Stalin' Jones is earnest, persuasive and energetic. The trustees welcome him to the board and quickly forgive his humorless political-correctness. He talks of 'diversity', 'relevance', 'social change', 'equality' and 'communities', but his eye is on that huge bequest. Alain first came to notice as a Trotskyite union official, who insinuated himself into one of the duller Trades Unions and turned it, through his passionate leadership, into a radical, headline-grabbing organization.  Middle age, and the rise of European federal socialism, had brought him quiet prosperity and charcoal suits, an ear in the current government, and a wide influence as a member of various Quangos (government bodies staffed by well-paid unelected courtiers).  He was employed as a 'consultant' by several organizations that relied on government contracts. After gaining the confidence of the trustees, and showing a surprising knowledge of mundane processes and the regulatory framework of charities, Alain launches his plan.  The trust will expand their work by means of a bold IT initiative that will coordinate the interventions of several 'caring agencies', and provide  emergency cover, a special Website so anxious relatives can see how their elderly charges are doing, and a vastly more efficient way of coordinating the work of the volunteer carers. It will also provide a special-purpose site that gives 'social networking' facilities, rather like Facebook, to the few elderly folk on the lists with access to the internet. The trustees perk up. Their own experience of the internet is restricted to the occasional scanning of railway timetables, but they can see that it is 'relevant'. In his next report to the other trustees, Alain proudly announces that all this glamorous and exciting technology can be paid for by a grant from the government. He admits darkly that he has influence. True to his word, the government promises a grant of a size that is an order of magnitude greater than any budget that the trustees had ever handled. There was the understandable proviso that the company that would actually do the IT work would have to be one of the government's preferred suppliers and the work would need to be tendered under EU competition rules. The only company that tenders, a multinational IT company with a long track record of government work, quotes ten million pounds for the work. A trustee questions the figure as it seems enormous for the reasonably trivial internet facilities being built, but the IT Salesmen dazzle them with presentations and three-letter acronyms until they subside into quiescent acceptance. After all, they can’t stay locked in the Twentieth century practices can they? The work is put in hand with a large project team, in a splendid glass building near west London. The trustees see rooms of programmers working diligently at screens, and who talk with enthusiasm of the project. Paul, the project manager, looked through his resource schedule with growing unease. His initial excitement at being given his first major project hadn’t lasted. He’d been allocated a lackluster team of developers whose skills didn’t seem right, and he was allowed only a couple of contractors to make good the deficit. Strangely, the presentation he’d given to his management, where he’d saved time and resources with a OTS solution to a great deal of the development work, and a sound conservative architecture, hadn’t gone down nearly as big as he’d hoped. He almost got the feeling they wanted a more radical and ambitious solution. The project starts slipping its dates. The costs build rapidly. There are certain uncomfortable extra charges that appear, such as the £600-a-day charge by the 'Business Manager' appointed to act as a point of liaison between the charity and the IT Company.  When he appeared, his face permanently split by a 'Mr Sincerity' smile, they'd thought he was provided at the cost of the IT Company. Derek, the DBA, didn’t have to go to the server room quite some much as he did: but It got him away from the poisonous despair of the development group. Wave after wave of events had conspired to delay the project.  Why the management had imposed hideous extra bureaucracy to cover ISO 9000 and 9001:2008 accreditation just as the project was struggling to get back on-schedule was  beyond belief.  Then  the Business manager was coming back with endless changes in scope, sorrowing saying that the Trustees were very insistent, though hopelessly out in touch with the reality of technical challenges. Suddenly, the costs mount to the point of consuming the government grant in its entirety. The project remains tantalizingly just out of reach. Alain Jones gives an emotional rallying speech at the trustees review meeting, urging them not to lose their nerve. Sadly, the trustees dip into the accumulated capital of the trust, the seed-corn of all their revenues, in order to save the IT project. A few months later it is all over. The IT project is never delivered, even though it had seemed so incredibly close.  With the trust's capital all gone, the activities it funded have to be terminated and the trust becomes just a shell. There aren't even the funds to mount a legal challenge against the IT company, even had the trust's solicitor advised such a foolish thing. Alain leaves as suddenly as he had arrived, only to pop up a few months later, bronzed and rested, at another charity. The IT workers who were permanent employees are dispersed to other projects, and the contractors leave to other contracts. Within months the entire project is but a vague memory. One or two developers remain  puzzled that their managers had been so obstructive when they should have welcomed progress toward completion of the project, but they put it down to incompetence and testosterone. Few suspected that they were actively preventing the project from getting finished. The relationships between the IT consultancy, and the government of the day are intricate, and made more complex by the Private Finance initiatives and political patronage.  The losers in this case were the taxpayers, and the beneficiaries of the trust, and, perhaps the soul of the original benefactor of the trust, whose bid to give his name some immortality had been scuppered by smooth-talking white-collar political apparatniks.  Even now, nobody is certain whether a crime was ever committed. The perfect heist, I guess. Where’s the victim? "I hear that Daisy’s cottage is up for sale. She’s had to go into a care home.  She didn’t want to at all, but then there is nobody to keep an eye on her since she had that minor stroke a while back.  A charity used to help out. The ‘social’ don’t have the funding, evidently for community care. Yes, her old cat was put down. There was a good clearout, and now the house is all scrubbed and cleared ready for sale. The skip was full of old photos and letters, memories. No room in her new ‘home’."

  • Nice take on Open Source

    - by EmbeddedInsider
    I just revisited the “Micro Framework”- Microsoft’s bootable runtime, essentially an OS that allows managed code to run on small 32bit CPUs, even without Memory Management.  Things are happening http://msdn.microsoft.com/en-us/netframework/bb267253.aspx Abstract The Microsoft .NET Micro Framework is a bootable runtime module that brings the advantages of .NET programming to devices too resource-constrained to run other Microsoft embedded platforms. The benefits of developing with the .NET Micro Framework include the C# programming language, a managed execution environment, a substantial subset of the .NET libraries, and Visual Studio™ deployment and debugging. In this white paper we explain why the .NET Micro Framework is an ideal choice for embedded development and provide technical details of the platform’s Hardware Abstraction Layer (HAL) and Common Language Runtime (CLR). “Micro Framework” is an interesting product, it is very low cost, like zero. And it is largely community controlled under the Apache License.  A partner network is building, and the application environment is .NET. I have been following this for some time, and the community open source approach seems to be working.  There are new features/packages emerging, for example an F# programming language (ARGH! I am still wresting with VB and C#). Anyway, what I found most interesting was a port to Tron.  Tron is a very popular Japanese open source intuitive.  It is a very real time, very compact kernel, and is, like the Micro Framework, ‘free as beer’.  One limit on MF was it was not real time.  But the merger with Tron may eliminate that problem.  Certainly, if I were dealing with a consumer product with quantities in the millions (like a SmartGrid device, or a toy) I would seriously consider something out of this technology pool.

  • Mission 26 Captures Endeavour’s Last Trip in Stop Motion

    - by Jason Fitzpatrick
    On September 21, 2012 the Space Shuttle Endeavour was delivered to the Los Angeles International Airport and spent the next three days being slowly transported 12 miles to the California Science Center. One dedicated team of photographers captured the whole thing. Lead by Matthew Givot, the group followed the shuttle for three straight days, photographing it around the clock. The Endeavor started on Thursday night and went on until Sunday night, with very little sleep to no sleep. The only thing that kept us going was pure love of the art and adrenaline. One thing that stood out the most for me, while I was shooting, was the people of Los Angeles. It was so powerful to see the excitement on peoples faces and the pride of their home town. No matter how many times I would see the Shuttle it would never get old. This has been an amazing experience that I will never forget. My hope is that this film will show you the amount of dedicated people and teamwork that it took to get the Endeavour to its new home. Enjoy. The end result of their labor is the above video, a beautiful time-lapse video of Endeavour’s journey from the airport to its hanger at the California Science Center.

    I tried installing fbreader, following all the steps, but ended up with unmet dependencies, i also think a file is referenced in two locations at once and hence killing it.. any ideas how I can fix it? i've done alot of research and tried: simon@simon-Studio-1558:~$ sudo apt-get -f install Reading package lists...

  • New Whitepaper: Best Practices for Gathering EBS Database Statistics

    - by Elke Phelps (Oracle Development)
    Most Oracle Applications DBAs and E-Business Suite users understand the importance of accurate database statistics.  Missing, stale or skewed statistics can adversely affect performance.  Oracle E-Business Suite statistics should only be gathered using FND_STATS or the Gather Statistics concurrent request. Gathering statistics with DBMS_STATS or the desupported ANALYZE command may result in suboptimal executions plans for E-Business Suite. Our E-Business Suite Performance Team has been busy implementing and testing new features for gathering statistics using FND_STATS in Oracle E-Business Suite databases.  The new features and guidelines for when and how to gather statistics are published in the following whitepaper: Best Practices for Gathering Statistics with Oracle E-Business Suite (Note 1586374.1) The new white paper details the following options for gathering statistics using FND_STATS and the Gather Statistics concurrent request:: History Mode - backup existing statistics prior to gather new statistics GATHER_AUTO Option - gather statistics for tables based upon % change Histograms - collect statistics for histograms AUTO Sampling - use the new FND_STATS feature that supports the AUTO option for using AUTO sample size Extended Statistics - use the new FND_STATS feature that supports the creation of column groups and automatic statistics collection on the column groups when table statistics are gathered Incremental Statistics - gather incremental statistics for partitioned tables The new white paper also includes examples and performance test cases for the following: Extended Optimizer Statistics Incremental Statistics Gathering Concurrent Statistics Gathering This white paper includes details about the standalone Oracle E-Business Suite Release 11i and 12 patches that are required to take advantage of this new functionality. Your feedback is welcome We would be very interested in hearing about your experiences with these new options for gathering statistics.  Please feel free to post your comments here or drop us a line privately.Related Oracle OpenWorld 2013 Session Getting Optimal Performance from Oracle E-Business Suite (CON8485) Related My Oracle Support Notes Collecting Statistics with Oracle EBS 11i and R12 (Note 368252.1) Non-EBS Related Blogs, White Papers and My Oracle Support Notes  Oracle Optimizer Blog Understanding Optimizer Statistic (white paper) Fixed Objects Statistics(GATHER_FIXED_OBJECTS_STATS) Considerations (Note 798257.1)

  • Windows Azure Evolution &ndash; TFS Integration (WAWS Part 2)

    - by Shaun
    So this is the fourth blog post about the new features of Windows Azure and the second part of Windows Azure Web Sites. But this is not just focus on the WAWS since the function I’m going to introduce is available in both Windows Azure Web Sites and Windows Azure Cloud Service (a.k.a. hosted service). In the previous post I talked about the Windows Azure Web Sites and how to use its gallery to build a WordPress personal blog without coding. Besides the gallery we can create an empty web site and upload our website from vary approaches. And one of the highlighted feature here is that, we can make our web site integrated with a source control service, such as TFS and Git, so that it will be deployed automatically once a new commit or build available.   Create New Empty Web Site In the developer portal when creating a new web site, we can select QUICK CREATE item. This will create an empty web site with only one shared instance without any database associated. Let’s specify the URL, region and subscription and click OK. After a few seconds our website will be ready. And now we can click the BROWSE button to open this empty website. As you can see there is a welcome page available in my website even thought I didn’t upload or deploy anything. This means even though the website will be charged even before anything was deployed, similar as the cloud service (hosted service). It is because once we created a website, Windows Azure platform had arranged a hosting process (w3wp.exe) in the group of virtual machines.   Create Project in TFS Preview Service and Setup Link Currently the Windows Azure Web Sites can integrate with TFS and Git as its deployment source, and it only support the Microsoft TFS Preview Service for now. I will not deep into how to use the TFS preview service in this post but once we click into the website we had just created and then clicked the “Set up TFS publishing”, there will be a dialog helping us to connect to this service. If you don’t have an account you can click the link shown below to request one. Assuming we have already had an account of TFS service then we need to create a new project firstly. Go to your TFS service website and create a new project, giving the project name, description and the process template. Then, back to the developer portal and clicked the “Set up TFS publishing” link. In the popping up window I will provide my TFS service URL and click the “Authorize now” link. Click “Accept” button to allow my windows azure to connect to my TFS service. Then it will be back to the developer portal and list all projects in my account. Just select the one I had just created and click OK. Then our website is linking to the TFS project I specified and finally it will show similar like this below. This means the web site had been linked to the TFS successfully.   Work with TFS Preview Service in VS2010 In the figure above there are some links to guide us how to connect to the TFS server through Visual Studio 2010 and 2012 RC. If you are using Visual Studio 2012 RC, you don’t need any extension. But if you are using Visual Studio 2010 you must have SP1 and KB2581206 installed. To connect to my TFS service just open the Visual Studio and in the Team Explorer, we can add a new TFS server and paste the URL of my TFS service from the developer portal. And select the project I had just created, then it will be listed in my Team Explorer. Now let’s start to build our website. Since the website we are going to build will be deployed to WAWS, it’s NOT a cloud service, NOT a web role. So in this case we need to create a normal ASP.NET web application. For example, an ASP.NET MVC 3 web application. Next, right click on the solution and select “Add Solution to Source Control”, select the project I had just created. Then check my code in. Once the check-in finished we can see that there is a build running in the TFS server. And if we back to the developer portal, we will see in our web site deployment page there’s a deployment running. In fact, once we linked our web site to our TFS then it will create a new build definition in our TFS project. It will be triggered by each check-in and deploy to the web site we linked automatically. So that when our code had been compiled it will be published to our web site from our TFS server. Once the build and deployment finished we can see it’s now active on our developer portal. Now we can see the web site that created from my Visual Studio and deployed by my TFS.   Continue Deployment through VS and TFS A big benefit when using TFS publishing is the continue deployment. Now if I changed some code in my Visual Studio, for example update some text on the home page and check in my changes, then it will trigger an new build and deploy to my WAWS automatically. And even more, if we wanted to rollback to a previous version we can just select an existing deployment listed in the portal and click REDEPLOY at the bottom.   Q&A: Can Web Site use Storage work with a Worker Role? Stacy asked a question in my previous post, which was “can a web site use Windows Azure Storage and furthermore working with a worker role”. Since the web site is deployed on the windows azure virtual machines in data center, it must be able to use all windows azure features such as the storage, SQL databases, CDN, etc.. But since when using web site we normally have a standard ASP.NET web application, PHP website or NodeJS, the windows azure SDK was not referenced by default. But we can add them by ourselves. In our sample project let’s right click on my MVC project and clicked the “Manage NuGet packages”. And in the dialog I will search windows azure packages and select the “Windows Azure Storage” to install. Then we will have the assemblies to access windows azure storage such as tables, queues and blobs. Since I have a storage account already, let’s have a quick demo, just to list all blobs in a container. The code would be like this. 1: using System; 2: using System.Collections.Generic; 3: using System.Linq; 4: using System.Web; 5: using System.Web.Mvc; 6: using Microsoft.WindowsAzure; 7: using Microsoft.WindowsAzure.StorageClient; 8:  9: namespace WAASTFSDemo.Controllers 10: { 11: public class HomeController : Controller 12: { 13: public ActionResult Index() 14: { 15: ViewBag.Message = "Welcome to Windows Azure!"; 16:  17: var credentials = new StorageCredentialsAccountAndKey("[STORAGE_ACCOUNT]", "[STORAGE_KEY]"); 18: var account = new CloudStorageAccount(credentials, false); 19: var client = account.CreateCloudBlobClient(); 20: var container = client.GetContainerReference("shared"); 21: ViewBag.Blobs = container.ListBlobs().Select(b => b.Uri.AbsoluteUri); 22:  23: return View(); 24: } 25:  26: public ActionResult About() 27: { 28: return View(); 29: } 30: } 31: } 1: @{ 2: ViewBag.Title = "Home Page"; 3: } 4:  5: <h2>@ViewBag.Message</h2> 6: <p> 7: To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website">http://asp.net/mvc</a>. 8: </p> 9: <div> 10: <ul> 11: @foreach (var blob in ViewBag.Blobs) 12: { 13: <li>@blob</li> 14: } 15: </ul> 16: </div> And then just check in the code, it will be deployed to my web site. Finally we can see the blobs in my storage.   This is just an example but it proves that web sites can connect to storage, table, blob and queue as well. So the answer to Stacy should be “yes”. The web site can use queue storage to work with worker role.   Summary In this post I demonstrated how to integrate with TFS from Windows Azure Web Sites. You can see our website can be built, uploaded and deployed automatically by TFS service. All we need to do is to provide the TFS name and select the project. Not only the Windows Azure Web Site, in this upgrade the Windows Azure Cloud Services (hosted service) can be published through TFS as well. Very similar as what we have shown below. But currently, only Microsoft TFS Service Preview can be integrated with Windows Azure. But I think in the future we can link the TFS in our enterprise and some 3rd party TFS such as CodePlex to Windows Azure.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.
