  • My Tech Ed North America Preview - Content Edition

    - by Chris Gardner
    As I promised in my last post, I feel the need to give you a rundown on all the technical content I am looking forward to checking out at Tech Ed this year. We shall start with the content I know I'll be able to see. This would be some demo stations in the Technical Learning Center. I will DEFINITELY be checking out the Windows Phone Device Bar. I will admit that I am a bit of a phone snob, and I just want to manhandle all that sexy, sexy tech. I am also planning on talking to the Windows Phone team and the Azure team. Year after year, I end up spending more time in either the TLC or taking certification tests than anywhere else. This leads me to the one "Exam Cram" session I hope to attend. There is a session to cram for 70-599: Designing and Developing Windows Phone Applications. I know this seems odd. I'm (sort of) an XNA guru. However, I'm not that up on my Silverlight. I know enough to add Silverlight to an XNA project. Now, let's talk breakout sessions. We always need to keep track of where we're going. I know, I talk about solving problems over forcing buzz words. However, it is important to know what those buzz words before you tell people not to use them. For this, we will look to the "What's New in Visual Studio 11" and "What's New in Microsoft .NET Framework 4.5." Of course, we do talk bad about buzz words around here. For this, I'm really looking forward to "Visual C#/Visual Basic: Becoming a Guru with Existing Features." I still have .NET 2 tricks that are crucial to my internal libraries. In depth knowledge will NEVER trump shortcut libraries. There is a session in ASP.NET for phones and tablets. For those of you that have not tried to use ASP.NET on a mobile device, there is one thing you really need to understand. Mobile devices don't use scroll bars. That's right; the thing with the least screen real estate doesn't use scroll bars. Thus, I am hoping this session will give some good advice in having an ASP.NET site target both mobile and desktop. The last "business only" session "The Accidental Team Foundation Server Admin." T & W Operations is a VERY small business. As such, I am the TFS admin because I'm the developer that is also the SQL Guru. I keep my server up, but it'd be nice to know some really cool tricks for the part time guy. This leads us the the fun sessions. Coding4Fun has a Kinect session. The Twitter followers will remember that I now have a Kinect for Windows sitting on my desk at work. I have gotten pretty handy with the device, but I KNOW I'm missing some good stuff. Finally, we come to Brian Prince's session on "Making Crazy Money with Games and the Cloud." Never mind the fact that we're using Azure at work. Never mind the fact that I'm actually using the cloud in a game. Never mind the fact that the session has the terms "Crazy Money" and "Games" in the title. If you've never seen Brian Prince speak, you're missing out. In the Hands-on-Labs, we are not allowed to make our own schedule. Instead, we're asked what sessions we can't miss, and they try to schedule around those times. This was the one session I said I couldn't miss. This should complete the technical content for the conference. Coming soon, I'll dig into the certifications I hope to attain. Then, we'll talk about the social activities for the week. Here's a preview of that. I am a member of The Krewe...

  • libimobiledevice wants to remove all my other packages

    - by Dror Cohen
    When running the command sudo apt-get remove libimobiledevice2 I get: The following packages will be REMOVED: ... gdm gdm-guest-session gnome-power-manager gnome-session gnome-session-bin gvfs-backends indicator-power indicator-session kde-plasma-desktop kde-standard libgpod-common libgpod4 libimobiledevice2 nautilus-share ubuntu-desktop upower` Is it really nessecary to remove all of my KDE and Gnome packages? The source of the problem is that the installed oneric package doesn't recognize my ios 5.1 - so I wanted to switch to the latest and greatest (1.0.7 and if that's not good enough I'll go to the dev version 1.1.2). I'm using oneric 64bit.

  • Umbraco Gold Partner and the last 6 months.

    - by Vizioz Limited
    As with a lot of blogs, unfortunately over the last 6 months our blog has been feeling some what neglected, the good news, is this has been due to us going from strength to strength :)In the last 6 months we have developed 5 more Microsites for Microsoft, we have helped a London agency fix a dire Umbraco implementation for a global drinks brand, built a great site for a famous food product range and most recently we are working with DairyMaster in Ireland building them a new website for their global distribution network and over the next couple of months we will be launching their new global marketing websites in 9 different languages.As well as working with these great clients, we also helped ResourceiT launch their new website in time for the Microsoft Global Partners conference.In December, Umbraco HQ launched their Umbraco Gold Partner programme, Vizioz was proud to be one of the first Gold Partners in the UK, showing our clients that we are investing our money in the product we promote, ensuring that Umbraco continues to go from strength to strength.

  • Gnome Terminal tabs ugly and oversized

    - by adamnfish
    Both gnome terminal and terminator (which I am using on my laptop these days) can be customised to look very pretty. By using full screen and keeping desktop clutter down to a minimum it's possible to get a good-sized area to work in, even on my little EeePC. However, there is one element that I don't seem to be able to control. Gnome's tabs are massively oversized and ugly at best. They don't fit into the theme at all which looks silly, but for me the biggest problem is the screen real estate that is wasted. On a small laptop screen in particular, it's a real problem. Is there a way to change these tabs? I realize it's possible to put them up the side of the window, but then they take up even more space! If this isn't possible with theme-ing or gnome configuration, are there any terminal programs like terminator that can handle the tabs themselves? (Ideally in a more elegant fashion!)

  • Devfish Joe Healy in Fort Lauderdale - Cloud Computing and Azure - 03/11/2010 MSDN Tiki Hut

    - by Rainer
    Devfish Joe Healy, Brian Hitney, and Herve Rogero presented excellent sessions on today's MSDN Tiki Hut Event about  Cloud Computing and Azure. This was an developer focused event, starting out with an overview about structure and platform, followed by working code samples running on the platform, and all needed information to get developers started on development for cloud applications. Participants had Q&A opportunities after each session and made good use of it. I am sure that a lot of developers will jump on the Azure train. Azure is on top of my dev project list after that great event! This platform offers endless opportunities for development and businesses. The cloud environment in general is safer, scales better, and is far more cost effective compared to run and maintain your own data center. Posted: Rainer Habermann

  • Would you go by WPF or WinForms? [on hold]

    - by Lorem Ipsum
    Consider the following project facts/requirements: Desktop app with try icon and notification system Forms over data Quick response needed Internal app in big corporation planned to be hosted on Windows Vista, later maybe Windows 8.x Operating system slowed down by many group policies (frequently changing GPO) No special graphic requirements So, would you go by WPF or WinForms? Edit: Please bear in mind the facts/requirements I mentioned above. The application will run on corporate machines which are very slow and without really good graphical acceleration. The crucial is to have really quick response and start time.

  • wordpress.com to self-hosted wordpress blog

    - by sAc
    Hello, I have been writing articles on the wordpress.com blog, now i am looking to move it to self-hosted wordpress blog but i wonder: 1) Should i move all my articles on the new blog or just put an article on my last blog that more articles will be posted on my new blog? 2) If i move all articles on my new blog, i am not sure about how google will react to it because there are articles with good number of visitors, won't this be seo-un-friendly because i am not sure but google will re-create page reputation stuff, etc or those articles will have same popularity even if i move elsewhere? 3) What are the implications and side-effects in moving from wordpress.com blog to self-hosted wordpress blog? Thanks

  • ATI proprietary driver performance?

    - by Axel
    I'm about to (at least, want to..) buy a laptop with an ATI Radeon HD 4250, and I haven't a good opinion on ATI's drivers. How is the actual performance of the open/proprietary driver (currently I have nVidia, and I'm very satisfied)? The intended use for the laptop is: watching videos, programming in Java/PHP/maybe Qt... but, I like to know if Compiz runs well. Yes, I'm a hardcore (?) programmer that uses Compiz. :P Someone has this GPU? Experiences? Thoughts? Thanks! :D

  • What’s the use of code reuse?

    - by Tony Davis
    All great developers write reusable code, don’t they? Well, maybe, but as with all statements regarding what “great” developers do or don’t do, it’s probably an over-simplification. A novice programmer, in particular, will encounter in the literature a general assumption of the importance of code reusability. They spend time worrying about DRY (don’t repeat yourself), moving logic into specific “helper” modules that they can then reuse, agonizing about the minutiae of the class structure, inheritance and interface design that will promote easy reuse. Unfortunately, writing code specifically for reuse often leads to complicated object hierarchies and inheritance models that are anything but reusable. If, instead, one strives to write simple code units that are highly maintainable and perform a single function, in a concise, isolated fashion then the potential for reuse simply “drops out” as a natural by-product. Programmers, of course, care about these principles, about encapsulation and clean interfaces that don’t expose inner workings and allow easy pluggability. This is great when it helps with the maintenance and development of code but how often, in practice, do we actually reuse our code? Most DBAs and database developers are familiar with the practical reasons for the limited opportunities to reuse database code and its potential downsides. However, surely elsewhere in our code base, reuse happens often. After all, we can all name examples, such as date/time handling modules, which if we write with enough care we can plug in to many places. I spoke to a developer just yesterday who looked me in the eye and told me that in 30+ years as a developer (a successful one, I’d add), he’d never once reused his own code. As I sat blinking in disbelief, he explained that, of course, he always thought he would reuse it. He’d often agonized over its design, certain that he was creating code of great significance that he and other generations would reuse, with grateful tears misting their eyes. In fact, it never happened. He had in his head, most of the algorithms he needed and would simply write the code from scratch each time, refining the algorithms and tailoring the code to meet the specific requirements. It was, he said, simply quicker to do that than dig out the old code, check it, correct the mistakes, and adapt it. Is this a common experience, or just a strange anomaly? Viewed in a certain light, building code with a focus on reusability seems to hark to a past age where people built cars and music systems with the idea that someone else could and would replace and reuse the parts. Technology advances so rapidly that the next time you need the “same” code, it’s likely a new technique, or a whole new language, has emerged in the meantime, better equipped to tackle the task. Maybe we should be less fearful of the idea that we could write code well suited to the system requirements, but with little regard for reuse potential, and then rewrite a better version from scratch the next time.

  • Talking JavaOne with Rock Star Martijn Verburg

    - by Janice J. Heiss
    JavaOne Rock Stars, conceived in 2005, are the top-rated speakers at each JavaOne Conference. They are awarded by their peers, who, through conference surveys, recognize them for their outstanding sessions and speaking ability. Over the years many of the world’s leading Java developers have been so recognized. Martijn Verburg has, in recent years, established himself as an important mover and shaker in the Java community. His “Diabolical Developer” session at the JavaOne 2011 Conference got people’s attention by identifying some of the worst practices Java developers are prone to engage in. Among other things, he is co-leader and organizer of the thriving London Java User Group (JUG) which has more than 2,500 members, co-represents the London JUG on the Executive Committee of the Java Community Process, and leads the global effort for the Java User Group “Adopt a JSR” and “Adopt OpenJDK” programs. Career highlights include overhauling technology stacks and SDLC practices at Mizuho International, mentoring Oracle on technical community management, and running off shore development teams for AIG. He is currently CTO at jClarity, a start-up focusing on automating optimization for Java/JVM related technologies, and Product Advisor at ZeroTurnaround. He co-authored, with Ben Evans, "The Well-Grounded Java Developer" published by Manning and, as a leading authority on technical team optimization, he is in high demand at major software conferences.Verburg is participating in five sessions, a busy man indeed. Here they are: CON6152 - Modern Software Development Antipatterns (with Ben Evans) UGF10434 - JCP and OpenJDK: Using the JUGs’ “Adopt” Programs in Your Group (with Csaba Toth) BOF4047 - OpenJDK Building and Testing: Case Study—Java User Group OpenJDK Bugathon (with Ben Evans and Cecilia Borg) BOF6283 - 101 Ways to Improve Java: Why Developer Participation Matters (with Bruno Souza and Heather Vancura-Chilson) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Kirk Pepperdine, Ellen Kraffmiller and Henri Tremblay) When I asked Verburg about the biggest mistakes Java developers tend to make, he listed three: A lack of communication -- Software development is far more a social activity than a technical one; most projects fail because of communication issues and social dynamics, not because of a bad technical decision. Sadly, many developers never learn this lesson. No source control -- Developers simply storing code in local filesystems and emailing code in order to integrate Design-driven Design -- The need for some developers to cram every design pattern from the Gang of Four (GoF) book into their source code All of which raises the question: If these practices are so bad, why do developers engage in them? “I've seen a wide gamut of reasons,” said Verburg, who lists them as: * They were never taught at high school/university that their bad habits were harmful.* They weren't mentored in their first professional roles.* They've lost passion for their craft.* They're being deliberately malicious!* They think software development is a technical activity and not a social one.* They think that they'll be able to tidy it up later.A couple of key confusions and misconceptions beset Java developers, according to Verburg. “With Java and the JVM in particular I've seen a couple of trends,” he remarked. “One is that developers think that the JVM is a magic box that will clean up their memory, make their code run fast, as well as make them cups of coffee. The JVM does help in a lot of cases, but bad code can and will still lead to terrible results! The other trend is to try and force Java (the language) to do something it's not very good at, such as rapid web development. So you get a proliferation of overly complex frameworks, libraries and techniques trying to get around the fact that Java is a monolithic, statically typed, compiled, OO environment. It's not a Golden Hammer!”I asked him about the keys to running a good Java User Group. “You need to have a ‘Why,’” he observed. “Many user groups know what they do (typically, events) and how they do it (the logistics), but what really drives users to join your group and to stay is to give them a purpose. For example, within the LJC we constantly talk about the ‘Why,’ which in our case is several whys:* Re-ignite the passion that developers have for their craft* Raise the bar of Java developers in London* We want developers to have a voice in deciding the future of Java* We want to inspire the next generation of tech leaders* To bring the disparate tech groups in London together* So we could learn from each other* We believe that the Java ecosystem forms a cornerstone of our society today -- we want to protect that for the futureLooking ahead to Java 8 Verburg expressed excitement about Lambdas. “I cannot wait for Lambdas,” he enthused. “Brian Goetz and his group are doing a great job, especially given some of the backwards compatibility that they have to maintain. It's going to remove a lot of boiler plate and yet maintain readability, plus enable massive scaling.”Check out Martijn Verburg at JavaOne if you get a chance, and, stay tuned for a longer interview yours truly did with Martijn to be publish on otn/java some time after JavaOne.

  • Why was Mr. Scott Scottish?

    - by iamjames
    It's a good question:  of all the engineers in the world, why choose a Scottish engineer?  The Gene Roddenberry probably chose a Scottish engineer because of this guy: That's James Watt, the same guy the unit of energy watt is named after.  He was a Scottish inventor and mechancial engineer who built the first made significant improvements to the steam engine.  Made sense in the 60's, however given the past hundred years if they were to make a new Star Trek they might have started with a German engineer (or maybe Japanese), but since World War II had ended barely 20 years earlier the 20-somethings that had survived the war were now 40-somethings and seeing a German engineer probably wouldn't have gone over too well.

  • Simple Excel Export with EPPlus

    - by Jesse Taber
    Originally posted on: http://geekswithblogs.net/GruffCode/archive/2013/10/30/simple-excel-export-with-epplus.aspxAnyone I’ve ever met who works with an application that sits in front of a lot of data loves it when they can get that data exported to an Excel file for them to mess around with offline. As both developer and end user of a little website project that I’ve been working on, I found myself wanting to be able to get a bunch of the data that the application was collecting into an Excel file. The great thing about being both an end user and a developer on a project is that you can build the features that you really want! While putting this feature together I came across the fantastic EPPlus library. This library is certainly very well known and popular, but I was so impressed with it that I thought it was worth a quick blog post. This library is extremely powerful; it lets you create and manipulate Excel 2007/2010 spreadsheets in .NET code with a high degree of flexibility. My only gripe with the project is that they are not touting how insanely easy it is to build a basic Excel workbook from a simple data source. If I were running this project the approach I’m about to demonstrate in this post would be front and center on the landing page for the project because it shows how easy it really is to get started and serves as a good way to ease yourself in to some of the more advanced features. The website in question uses RavenDB, which means that we’re dealing with POCOs to model the data throughout all layers of the application. I love working like this so when it came time to figure out how to export some of this data to an Excel spreadsheet I wanted to find a way to take an IEnumerable<T> and just have it dumped to Excel with each item in the collection being modeled as a single row in the Excel worksheet. Consider the following class: public class Employee { public int Id { get; set; } public string Name { get; set; } public decimal HourlyRate { get; set; } public DateTime HireDate { get; set; } } Now let’s say we have a collection of these represented as an IEnumerable<Employee> and we want to be able to output it to an Excel file for offline querying/manipulation. As it turns out, this is dead simple to do with EPPlus. Have a look: public void ExportToExcel(IEnumerable<Employee> employees, FileInfo targetFile) { using (var excelFile = new ExcelPackage(targetFile)) { var worksheet = excelFile.Workbook.Worksheets.Add("Sheet1"); worksheet.Cells["A1"].LoadFromCollection(Collection: employees, PrintHeaders: true); excelFile.Save(); } } That’s it. Let’s break down what’s going on here: Create a ExcelPackage to model the workbook (Excel file). Note that the ‘targetFile’ value here is a FileInfo object representing the location on disk where I want the file to be saved. Create a worksheet within the workbook. Get a reference to the top-leftmost cell (addressed as A1) and invoke the ‘LoadFromCollection’ method, passing it our collection of Employee objects. Behind the scenes this is reflecting over the properties of the type provided and pulling out any public members to become columns in the resulting Excel output. The ‘PrintHeaders’ parameter tells EPPlus to grab the name of the property and put it in the first row. Save the Excel file All of the heavy lifting here is being done by the ‘LoadFromCollection’ method, and that’s a good thing. Now, this was really easy to do, but it has some limitations. Using this approach you get a very plain, un-styled Excel worksheet. The column widths are all set to the default. The number format for all cells is ‘General’ (which proves particularly interesting if you have a DateTime property in your data source). I’m a “no frills” guy, so I wasn’t bothered at all by trading off simplicity for style and formatting. That said, EPPlus has tons of samples that you can download that illustrate how to apply styles and formatting to cells and a ton of other advanced features that are way beyond the scope of this post.

  • TDD and WCF behavior

    Some weeks ago I wanted to develop a WCF behavior using TDD. I have lost some time trying to use mocks. After a while i decided to just use a host and a client. I don’t like this approach but so far I haven’t found a good and fast solution to use Unit Test for testing a WCF behavior. To Implement my solution I had to : Create a Dummy Service Definition; Create the Dummy Service Implementation; Create a host; Create a client in my test; Create and Add the behavior; Dummy Service Definition This is just a simple service, composed of an Interface and a simple implementation. The structure is aimed to be easily customizable for my future needs.   Using Clauses : 1: using System.Runtime.Serialization; 2: using System.ServiceModel; 3: using System.ServiceModel.Channels; The DataContract: 1: [DataContract()] 2: public class MyMessage 3: { 4: [DataMember()] 5: public string MessageString; 6: } The request MessageContract: 1: [MessageContract()] 2: public class RequestMessage 3: { 4: [MessageHeader(Name = "MyHeader", Namespace = "http://dummyservice/header", Relay = true)] 5: public string myHeader; 6:  7: [MessageBodyMember()] 8: public MyMessage myRequest; 9: } The response MessageContract: 1: [MessageContract()] 2: public class ResponseMessage 3: { 4: [MessageHeader(Name = "MyHeader", Namespace = "http://dummyservice/header", Relay = true)] 5: public string myHeader; 6:  7: [MessageBodyMember()] 8: public MyMessage myResponse; 9: } The ServiceContract: 1: [ServiceContract(Name="DummyService", Namespace="http://dummyservice",SessionMode=SessionMode.Allowed )] 2: interface IDummyService 3: { 4: [OperationContract(Action="Perform", IsOneWay=false, ProtectionLevel=System.Net.Security.ProtectionLevel.None )] 5: ResponseMessage DoThis(RequestMessage request); 6: } Dummy Service Implementation 1: public class DummyService:IDummyService 2: { 3: #region IDummyService Members 4: public ResponseMessage DoThis(RequestMessage request) 5: { 6: ResponseMessage response = new ResponseMessage(); 7: response.myHeader = "Response"; 8: response.myResponse = new MyMessage(); 9: response.myResponse.MessageString = 10: string.Format("Header:<{0}> and Request was <{1}>", 11: request.myHeader, request.myRequest.MessageString); 12: return response; 13: } 14: #endregion 15: } Host Creation The most simple host implementation using a Named Pipe binding. The GetBinding method will create a binding for the host and can be used to create the same binding for the client. 1: public static class TestHost 2: { 3: 4: internal static string hostUri = "net.pipe://localhost/dummy"; 5:  6: // Create Host method. 7: internal static ServiceHost CreateHost() 8: { 9: ServiceHost host = new ServiceHost(typeof(DummyService)); 10:  11: // Creating Endpoint 12: Uri namedPipeAddress = new Uri(hostUri); 13: host.AddServiceEndpoint(typeof(IDummyService), GetBinding(), namedPipeAddress); 14:  15: return host; 16: } 17:  18: // Binding Creation method. 19: internal static Binding GetBinding() 20: { 21: NamedPipeTransportBindingElement namedPipeTransport = new NamedPipeTransportBindingElement(); 22: TextMessageEncodingBindingElement textEncoding = new TextMessageEncodingBindingElement(); 23:  24: return new CustomBinding(textEncoding, namedPipeTransport); 25: } 26:  27: // Close Method. 28: internal static void Close(ServiceHost host) 29: { 30: if (null != host) 31: { 32: host.Close(); 33: host = null; 34: } 35: } 36: } Checking the service A simple test tool check the plumbing. 1: [TestMethod] 2: public void TestService() 3: { 4: using (ServiceHost host = TestHost.CreateHost()) 5: { 6: host.Open(); 7:  8: using (ChannelFactory<IDummyService> channel = 9: new ChannelFactory<IDummyService>(TestHost.GetBinding() 10: , new EndpointAddress(TestHost.hostUri))) 11: { 12: IDummyService svc = channel.CreateChannel(); 13: try 14: { 15: RequestMessage request = new RequestMessage(); 16: request.myHeader = Guid.NewGuid().ToString(); 17: request.myRequest = new MyMessage(); 18: request.myRequest.MessageString = "I want some beer."; 19:  20: ResponseMessage response = svc.DoThis(request); 21: } 22: catch (Exception ex) 23: { 24: Assert.Fail(ex.Message); 25: } 26: } 27: host.Close(); 28: } 29: } Running the service should show that the client and the host are running fine. So far so good. Adding the Behavior Add a reference to the Behavior project and add the using entry in the test class. We just need to add the behavior to the service host : 1: [TestMethod] 2: public void TestService() 3: { 4: using (ServiceHost host = TestHost.CreateHost()) 5: { 6: host.Description.Behaviors.Add(new MyBehavior()); 7: host.Open();¨ 8: …  If you set a breakpoint in your behavior and run the test in debug mode, you will hit the breakpoint. In this case I used a ServiceBehavior. To add an Endpoint behavior you have to add it to the endpoints. 1: host.Description.Endpoints[0].Behaviors.Add(new MyEndpointBehavior()) To add a contract or an operation behavior a custom attribute should work on the service contract definition. I haven’t tried that yet.   All the code provided in this blog and in the following files are for sample use. Improvements I don’t like to instantiate a client and a service to test my behaviors. But so far I have' not found an easy way to do it. Today I am passing a type of endpoint to the host creator and it creates the right binding type. This allows me to easily switch between bindings at will. I have used the same approach to test Mex Endpoints, another post should come later for this. Enjoy !

  • Windows Azure Use Case: Agility

    - by BuckWoody
    This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx  Description: Agility in this context is defined as the ability to quickly develop and deploy an application. In theory, the speed at which your organization can develop and deploy an application on available hardware is identical to what you could deploy in a distributed environment. But in practice, this is not always the case. Having an option to use a distributed environment can be much faster for the deployment and even the development process. Implementation: When an organization designs code, they are essentially becoming a Software-as-a-Service (SaaS) provider to their own organization. To do that, the IT operations team becomes the Infrastructure-as-a-Service (IaaS) to the development teams. From there, the software is developed and deployed using an Application Lifecycle Management (ALM) process. A simplified view of an ALM process is as follows: Requirements Analysis Design and Development Implementation Testing Deployment to Production Maintenance In an on-premise environment, this often equates to the following process map: Requirements Business requirements formed by Business Analysts, Developers and Data Professionals. Analysis Feasibility studies, including physical plant, security, manpower and other resources. Request is placed on the work task list if approved. Design and Development Code written according to organization’s chosen methodology, either on-premise or to multiple development teams on and off premise. Implementation Code checked into main branch. Code forked as needed. Testing Code deployed to on-premise Testing servers. If no server capacity available, more resources procured through standard budgeting and ordering processes. Manual and automated functional, load, security, etc. performed. Deployment to Production Server team involved to select platform and environments with available capacity. If no server capacity available, standard budgeting and procurement process followed. If no server capacity available, systems built, configured and put under standard organizational IT control. Systems configured for proper operating systems, patches, security and virus scans. System maintenance, HA/DR, backups and recovery plans configured and put into place. Maintenance Code changes evaluated and altered according to need. In a distributed computing environment like Windows Azure, the process maps a bit differently: Requirements Business requirements formed by Business Analysts, Developers and Data Professionals. Analysis Feasibility studies, including budget, security, manpower and other resources. Request is placed on the work task list if approved. Design and Development Code written according to organization’s chosen methodology, either on-premise or to multiple development teams on and off premise. Implementation Code checked into main branch. Code forked as needed. Testing Code deployed to Azure. Manual and automated functional, load, security, etc. performed. Deployment to Production Code deployed to Azure. Point in time backup and recovery plans configured and put into place.(HA/DR and automated backups already present in Azure fabric) Maintenance Code changes evaluated and altered according to need. This means that several steps can be removed or expedited. It also means that the business function requesting the application can be held directly responsible for the funding of that request, speeding the process further since the IT budgeting process may not be involved in the Azure scenario. An additional benefit is the “Azure Marketplace”, In effect this becomes an app store for Enterprises to select pre-defined code and data applications to mesh or bolt-in to their current code, possibly saving development time.

  • What is your opinion on free software? [closed]

    - by Joe D
    I use mostly free software on my main machine, and most programs that I write come out under either the GPL or BSD. I dislike proprietary software and prefer not to use it if a free software alternative is viable (read as: good enough). What are your opinions on free software? Do you use or develop for it? Why do you use it? Why don't you? Are you as extremist as RMS, and use only free software?

  • The New Social Developer Community: a Q&A

    - by Mike Stiles
    In our last blog, we introduced the opportunities that lie ahead for social developers as social applications reach across every aspect and function of the enterprise. Leading the upcoming JavaOne Social Developer Program October 2 at the San Francisco Hilton is Roland Smart, VP of Social Marketing at Oracle. I got to ask Roland a few of the questions an existing or budding social developer might want to know as social extends beyond interacting with friends and marketing and into the enterprise. Why is it smart for developers to specialize as social developers? What opportunities lie in the immediate future that’s making this a critical, in-demand position? Social has changed the way we interact with brands and with each other across the web. As we acclimate to a new social paradigm we also look to extend its benefits into new areas of our lives. The workplace is a logical next step, and we're starting to see social interactions more and more in this context. But unlocking the value of social interactions requires technical expertise and knowledge of developing social apps that tap into the social graph. Developers focused on integrating social experiences into enterprise applications must be familiar with popular social APIs and must understand how to build enterprise social graphs of their own. These developers are part of an emerging community of social developers and are key to socially enabling the enterprise. Facebook rebranded their Preferred Developer Consultant Group (PDC) and the Preferred Marketing Developers (PMD) to underscore the fact developers are required inside marketing organizations to unlock the full potential of their platform. While this trend is starting on the marketing side with marketing developers, this is just an extension of the social developer concept that will ultimately drive social across the enterprise. What are some of the various ways social will be making its way into every area of enterprise organizations? How will it be utilized and what kinds of applications are going to be needed to facilitate and maximize these changes? Check out Oracle’s vision for the social-enabled enterprise. It’s a high-level overview of how social will impact across the enterprise. For example: HR can leverage social in recruiting and retentionSales can leverage social as a prospecting toolMarketing can use social to gain market insightCustomer support can use social to leverage community support to improve customer satisfaction while reducing service costOperations can leverage social improve systems That’s only the beginning. Once sleeves get rolled up and social developers and innovators get to work, still more social functions will no doubt emerge. What makes Java one of, if not the most viable platform on which to build these new enterprise social applications? Java is certainly one of the best platforms on which to build social experiences because there’s such a large existing community of Java developers. This means you can affordably recruit talent, and it's possible to effectively solicit advice from the community through various means, including our new Social Developer Community. Beyond that, there are already some great proof points Java is the best platform for creating social experiences at scale. Consider LinkedIn and Twitter. Tell us more about the benefits of collaboration and more about what the Oracle Social Developer Community is. What opportunities does that offer up and what are some of the ways developers can actively participate in and benefit from that community? Much has been written about the overall benefits of collaborating with other developers. Those include an opportunity to introduce yourself to the community of social developers, foster a reputation, establish an expertise, contribute to the advancement of the space, get feedback, experiment with the latest concepts, and gain inspiration. In short, collaboration is a tool that must be applied properly within a framework to get the most value out of it. The OSDC is a place where social developers can congregate to discuss the opportunities/challenges of building social integrations into their applications. What “needs” will this community have? We don't know yet. But we wanted to create a forum where we can engage and understand what social developers are thinking about, excited about, struggling with, etc. The OSDL can then step in if we can help remove barriers and add value in a serious and committed way so Oracle can help drive practice development.

  • Guidance for a C# developer to become better UI developer

    - by Pankaj Upadhyay
    I am a C# developer and had developed simple websites in regular asp.net(with asp.net controls) and a wpf application. Nowadays, I am trying myself in Asp.net MVC3 and been exposed to the HTML with Razor view Engine. To be honest, I am not too good or I should awful at my knowledge of HTML and CSS. Therefore, I keep posting questions now and then on SO for very simple tasks. This has made me very tired of the this Q&A development process. So, now i am thinking of learning the basics of HTML, CSS and maybe some Javascript. Therefore i would request you to guide me to become an efficient enough developer for these technologies. Something that won't take much time and get me up and running fast.

  • Sharing code in LGPL and proprietary software

    - by Martin
    Hi I'm working on a piece of software that'll be released as a dll under LGPL. The software interfaces with hardware from a small company that has provided me with the needed libraries and some code to use them correctly (not only headers but its all in a separate file). As far as i know, the same code is used in their proprietary software that they don't intend to open source but they'd be fine releasing the piece of code they've given me. Now here's the question: What license could be used on the code I got from the company? I guess using GPL or LGPL would make them violate GPL when using the same code in their other software. Is MIT a good idea? Is it ok to just include a file with MIT license on it in my otherwise LGPL:ed project? Since I'm not the copyright holder, I'd have to ask the company to apply the license obviously but that shouldn't be a problem. Thanks /Martin
