  • Kanban Tools Review

    - by GeekAgilistMercenary
    The first two sessions on Sunday were Collaboration and why it is so hard and the following, which was a perfect following session was on Kanban.  While in that second session two online Saas Style Tools were mentioned; AgileZen and Leankit.  I decided right then and there that I would throw together some first impressions and setup some sample projects.  I did this by setting up an account and creating the projects. Agile Zen Account Creation Setting up the initial account required an e-mail verification, which is understandable.  Within a few seconds it was mailed out and I was logged in. Setting Up the Kanban Board The initial setup of the board was pretty easy.  I maybe clicked around an extra few times, but overall everything I needed to use the tool was immediately available.  The representation of everything was very similar to what one expects in a real Kanban Board too.  This is a HUGE plus, especially if a team is smart and places this tool in a centrally viewable area to allow for visibility. Each of the board items is just like a post it, being blue, grey, green, pink, or one of another few colors.  Dragging them onto each swim lane on the board was flawless, making changes through the work super easy and intuitive. The other thing I really liked about AgileZen is that the Kanban Board had the swim lanes setup immediately.  One can change them, but when you know you immediately need a Ready Lane, Working Lane, and a Complete Lane it is nice to just have them right in front of you in the interface.  In addition, the Backlog is simply a little tab on the left hand side.  This is perfect for the Backlog Queue.  Out of the way, with the focus on the primary items. Once  I got the items onto the board I was easily able to get back to the actual work at hand versus playing around with the tool.  The fact that it was so easy to use, fast and easy UX, and overall a great layout put me back to work on things I needed to do versus sitting a playing with the tool.  That, in the end is the key to using these tools. LeanKit Kanban Account Creation Setting up the account got me straight into the online tool.  This I thought was pretty cool. Setting Up the Kanban Board Setting up the Kanban Board within Leankit was a bit of trouble.  There were multiple UX issues in regard to process and intuitiveness.  The Leankit basically forces one to design the whole board first, making no assumptions about how the board should look.  The swim lanes in my humble opinion should be setup immediately without any manipulation with the most common lanes;  ready, working, and complete. The other UX hiccup that I had a problem with is that as soon as I managed to get the swim lanes into place, I wanted to remove the redundant Backlog Lane.  The Backlog Lane, or Backlog Bucket should be somewhere that I accidentally added as a lane.  Then on top of that I screwed up and added an item inside the lane, which then prevented me from deleting the lane.  I had to go back out of the lane manipulation, remove the item, and then remove the excess lane.  Summary Leankit wasn't a bad interface, it just wasn't as good as AgileZen.  The AgileZen interface was just better UX design overall.  AgileZen also presents a much better user interface graphical design all together.  It is much closer to what the Kanban Board would look like if it were a physical Kanban Board.  Since one of the HUGE reasons for Kanban is to increase visibility, the fact the design is similar to what a real Kanban Board is actually a pretty big deal. This is an image (click for larger) that shows the two Kanban Boards side by side.  The one on the left is AgileZen and the right is Leankit. Original Entry

  • Miami 311: Built on Windows Azure

    - by Josh Holmes
    This is a cool use of Azure. The city of Miami tool their “311” data around potholes, trash pickup issues, recycling issues, broken sidewalks and the like and put that data in Azure. The next step is that they leveraged Bing Maps and Silverlight to visualize those issues spread on a map of the city. The solution takes advantage of virtually unlimited storage and processing power, provides the ability to quickly address service requests and implement updates even during peak times such as hurricane season. If things change, the City can bring the solution on site or move to a physical facility, all based on  need and cost-effectiveness. As a result, residents logging on to Miami 311 can see on average 4,500 issues in progress - not represented as a ‘list', but located on a map in relation to other projects in their neighborhood .  A simple click on the map allows them to easily drill down to more and more specific details if they want. In short, they have turned what used to be represented by a meaningless list of data into useful information, and created  actionable and consumable knowledge that is relevant to the citizens of Miami. For Miami, their ‘service call to the city' becomes an interactive process they can follow - and the City has a new tool to manage and deliver outcomes. … When the city made the move to the web, they chose tools they knew and software they trust. The Microsoft Windows Azure cloud platform made it easy to do, and they used both Bing mapping and Silverlight to build a user friendly front end. According to Port25 (Miami 311: Built on Windows Azure - Port 25: The Open Source Community at Microsoft), it took two people 8 days to implement the whole system and they are going to open source their solution so that other cities can leverage it. I haven’t seen yet where and how they are going to release it but I’ll keep you posted if I find out.

  • 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.

  • Prioritizing Product Features

    - by Robert May
    A very common task in Agile Environments is prioritization.  Teams that are functioning well will prioritize new features, old features, the backlog, and any other source of stories for the team, and they’ll do it regularly. Not all teams are good at prioritizing according to the real return on investment that building stories will yield to the company.  This is unfortunate.  Too often, teams end up building features that are less valuable, and everyone seems to know it except perhaps the product owner!  Most features built into software are never even used.  Clearly, not much return for features that go unused. So how does a company avoid building features that add little value to the company?  This is a tough question to answer, but usually, this prioritization starts at the top with the executives of the company.  After all, they’re responsible for the overall vision of the company. Here’s what I recommend: Know your market. Know your customers and users. Know where you’re going and what you want to achieve. Implement the Vision Know Your Market We often see companies that don’t know their market.  Personally, I’m surprised by this.  These companies don’t know who their competitors are, don’t know what features make their product desirable in the market, and in many cases, get by with saying, “I’ve been doing this for XX years.  I know what the market wants!”  In many cases, they equate “marketing” with “advertising” and don’t understand the difference. This is almost never true.  Good companies will spend significant amounts of time and money finding out who they’re competing against and what makes their competitors successful in the marketplace.  Good companies understand that marketing involves more than just advertising.  Often, marketing is mostly research and analysis, not sales.  Until you understand your market, you cannot know what features will give you the best return on your investment dollar. Good companies have a marketing department and can answer the next important step which is to know your customers and your users. Know your Customers and Users First, note that I included both customers and users.  They’re often not the same thing.  Users use the product that you build.  Customers buy the product that you build.  It’s a subtle difference, but too often, I’ve seen companies that focus exclusively on one or the other and are not successful simply because they ignore an important part of the group. If your company is doing appropriate marketing, you know that these are two different aspects of your product and that both deserve attention to have a product that is successful in your target market.  Your marketing department should be spending a lot of time understanding these personas and then conveying that information to the company. I’m always surprised when development teams think that they can build a product that people want to use without understanding the users of that product.  Developers think differently than most people in the world.  They know what the computer is doing.  The computer isn’t magic to them.  So when they assume that they know how to build something, they bring with them quite a bit of baggage.  Never assume that you know your customer unless you’re regularly having interaction with them.  Also, don’t just leave this to Marketing or Product Management.  Take them time to get your developers out with the customers as well.  Developers are very smart people, and often, seeing how someone uses their software inspires them to make a much better product. Very often, because the users and customers aren’t know, teams will spend a significant amount of time building apps that are super flexible and configurable so that any possible combination of feature can be used.  This demonstrates a clear lack of understanding of the customer.  Most configuration questions can quickly be answered by talking to the customer.  In most cases, if your software requires significant setup and configuration before its usable, you probably don’t know your customers and users very well. Until you know your customers, you cannot know what features will be most valuable to your customers and you cannot build those features in a way that your customers can use. Know Where You’re Going and What You Want to Achieve Many companies suffer from not having a plan.  Executives will tell the team to make them a plan.  The team, not knowing their market and customers and users, will come up with a plan that doesn’t reflect reality and doesn’t consider ROI.  Management then wonders why the product is doing poorly in the market place. Instead of leaving this up to the teams, as executives, work with Marketing to understand what broad categories of features will sell the most product in the marketplace.  Then, once you’ve determined that, give this vision to the team and let them run with it.  Revise the vision as needed, but avoid changing streams frequently.  Sure, sometimes you need to, but often, executives will change priorities many times a month, leading to nothing more than confusion.  If the team has a vision, they’ll be able to execute that vision far better than they could otherwise. By knowing what products are most important, you can set budgetary goals and guidelines that will help you achieve the vision that was created. Implement the Vision Creating the vision is often where the general executives stop participating in the plan.  The team is responsible for implementing that vision.  Executives should attend showcases and and should remain aware of the progress that the team is making towards meeting the vision, however. Once a broad vision has been created, the team should break that vision down into minimal market features (MMF).  These MMFs should be sized using story points so that, using the team’s velocity, an estimated cost can be determined for each feature.  The product management team should then try to quantify the relative value of the MMFs based on customer feedback and interviews.  Once the value and cost of creating the feature is understood, a return on investment can be calculated.  The features should then be prioritized with the MMF’s that have the highest value and lowest cost rising to the top of features to implement.  Don’t let politics get in the way! Once the MMF’s have been prioritized, they should go through release planning to schedule them for implementation. Conclusion By having a good grasp on the strategy of the company, your Agile teams can be much more effective.  Each and every story the team is implementing will roll up into features that matter to the company and provide ROI to them.  The steps outlined in this post should be repeated on a regular basis.  I recommend reviewing them at least once per quarter to make sure that the vision hasn’t shifted and that the teams are still working on what matters most to the company.

  • Don&rsquo;t Kill the Password

    - by Anthony Trudeau
    A week ago Mr. Honan from Wired.com penned an article on security he titled “Kill the Password: Why a String of Characters Can’t Protect Us Anymore.” He asserts that the password is not effective and a new solution is needed. Unfortunately, Mr. Honan was a victim of hacking. As a result he has a victim’s vendetta. His conclusion is ill conceived even though there are smatterings of truth and good advice. The password is a security barrier much like a lock on your door. In of itself it’s not guaranteeing protection. You can have a good password akin to a steel reinforced door with the best lock money can buy, or you can have a poor password like “password” which is like a sliding lock like on a bathroom stall. But, just like in the real world a lock isn’t always enough. You can have a lock, security system, video cameras, guard dogs, and even armed security guards; but none of that guarantees your protection. Even top secret government agencies can be breached by someone who is just that good (as dramatized in movies like Mission Impossible). And that’s the crux of it. There are real hackers out there that are that good. Killer coding ninja monkeys do exist! We still have locks on our doors, because they still serve their role. Passwords are no different. Security doesn’t end with the password. Most people would agree that stuffing your mattress with your life savings isn’t a good idea even if you have the best locks and security system. Most people agree its safest to have the money in a bank. Essentially this is compartmentalization. Compartmentalization extends to the online world as well. You’re at risk if your online banking accounts are linked to the same account as your social networks. This is especially true if you’re lackadaisical about linking those social networks to outside sources including apps. The object here is to minimize the damage that can be done. An attacker should not be able to get into your bank account, because they breached your Twitter account. It’s time to prioritize once you’ve compartmentalized. This simply means deciding how much security you want for the different compartments which I’ll call security zones. Social networking applications like Facebook provide a lot of security features. However, security features are almost always a compromise with privacy and convenience. It’s similar to an engineering adage, but in this case it’s security, convenience, and privacy – pick two. For example, you might use a safe instead of bank to store your money, because the convenience of having your money closer or the privacy of not having the bank records is more important than the added security. The following are lists of security do’s and don’ts (these aren’t meant to be exhaustive and each could be an article in of themselves): Security Do’s: Use strong passwords based on a phrase Use encryption whenever you can (e.g. HTTPS in Facebook) Use a firewall (and learn to use it properly) Configure security on your router (including port blocking) Keep your operating system patched Make routine backups of important files Realize that if you’re not paying for it, you’re the product Security Don’ts Link accounts if at all possible Reuse passwords across your security zones Use real answers for security questions (e.g. mother’s maiden name) Trust anything you download Ignore message boxes shown by your system or browser Forget to test your backups Share your primary email indiscriminately Only you can decide your comfort level between convenience, privacy, and security. Attackers are going to find exploits in software. Software is complex and depends on other software. The exploits are the responsibility of the software company. But your security is always your responsibility. Complete security is an illusion. But, there is plenty you can do to minimize the risk online just like you do in the physical world. Be safe and enjoy what the Internet has to offer. I expect passwords to be necessary just as long as locks.

  • A Closer Look at the HiddenInput Attribute in MVC 2

    - by Steve Michelotti
    MVC 2 includes an attribute for model metadata called the HiddenInput attribute. The typical usage of the attribute looks like this (line #3 below): 1: public class PersonViewModel 2: { 3: [HiddenInput(DisplayValue = false)] 4: public int? Id { get; set; } 5: public string FirstName { get; set; } 6: public string LastName { get; set; } 7: } So if you displayed your PersonViewModel with Html.EditorForModel() or Html.EditorFor(m => m.Id), the framework would detect the [HiddenInput] attribute metadata and produce HTML like this: 1: <input id="Id" name="Id" type="hidden" value="21" /> This is pretty straight forward and allows an elegant way to keep the technical key for your model (e.g., a Primary Key from the database) in the HTML so that everything will be wired up correctly when the form is posted to the server and of course not displaying this value visually to the end user. However, when I was giving a recent presentation, a member of the audience asked me (quite reasonably), “When would you ever set DisplayValue equal to true when using a HiddenInput?” To which I responded, “Well, it’s an edge case. There are sometimes when…er…um…people might want to…um…display this value to the user.” It was quickly apparent to me (and I’m sure everyone else in the room) what a terrible answer this was. I realized I needed to have a much better answer here. First off, let’s look at what is produced if we change our view model to use “true” (which is equivalent to use specifying [HiddenInput] since “true” is the default) on line #3: 1: public class PersonViewModel 2: { 3: [HiddenInput(DisplayValue = true)] 4: public int? Id { get; set; } 5: public string FirstName { get; set; } 6: public string LastName { get; set; } 7: } Will produce the following HTML if rendered from Htm.EditorForModel() in your view: 1: <div class="editor-label"> 2: <label for="Id">Id</label> 3: </div> 4: <div class="editor-field"> 5: 21<input id="Id" name="Id" type="hidden" value="21" /> 6: <span class="field-validation-valid" id="Id_validationMessage"></span> 7: </div> The key is line #5. We get the text of “21” (which happened to be my DB Id in this instance) and also a hidden input element (again with “21”). So the question is, why would one want to use this? The best answer I’ve found is contained in this MVC 2 whitepaper: When a view lets users edit the ID of an object and it is necessary to display the value as well as to provide a hidden input element that contains the old ID so that it can be passed back to the controller. Well, that actually makes sense. Yes, it seems like something that would happen *rarely* but, for those instances, it would enable them easily. It’s effectively equivalent to doing this in your view: 1: <%: Html.LabelFor(m => m.Id) %> 2: <%: Model.Id %> 3: <%: Html.HiddenFor(m => m.Id) %> But it’s allowing you to specify it in metadata on your view model (and thereby take advantage of templated helpers like Html.EditorForModel() and Html.EditorFor()) rather than having to explicitly specifying everything in your view.

    I am scheduled to share on NuGet (http://nuget.codeplex.com/) at the Deerfield Beach Coder’s Café on March 1st, 2011. My goal for this talk is to present demos and content covering how to leverage this new neat utility to easily “package” .Net-based binaries or tools and share them with others, who in-turn, can just as easy reference and readily use that same package in their Visual Studio 2010 .Net projects. Scott Hanselman has recently blogged in great detail on creating NuGet packages. For hosting a local NuGet package repository, Jon Galloway has a nice article update with a complete PowerShell script to simplify downloading the default feed packages which can be accessed here. Information on my upcoming talk can be found at: http://www.fladotnet.com/Reg.aspx?EventID=514 The following is a brief abstract of the talk: NuGet (formerly known as NuPack) is a free, open source developer focused package management system for the .NET platform intent on simplifying the process of incorporating third party libraries into a .NET application during development. NuGet is a member of the ASP.NET Gallery in the Outercurve Foundation. In this session we will: Discuss the concept, vision and goal behind NuGet See NuGet in action within an ASP.Net MVC project Look at the NuGet integration in Microsoft WebMatrix Create a NuGet package for our demo library Explore the NuGet Project site Configure a NuGet package feed for a local network Solicit attendees input and feedback on the tool  Look forward to meeting you all there. --Sam

  • Integrating Windows Form Click Once Application into SharePoint 2007 &ndash; Part 1 of 2

    - by Kelly Jones
    Last year, I had the opportunity to build a solution that involved integrating a Windows Form application into a SharePoint 2007 (WSS version 3.0). In this post, I’ll layout our architecture thinking and in part two, I’ll describe the technical details. Business Case Our challenge was this: we needed an easy way for a small group of our users to upload documents, in batches.  They also needed to quickly set the meta data values, as well as set security on individual files. Using the out of the box uploads just didn’t fit.  The single file upload allows set the meta data, but our users would be uploading dozens of files.  The multiple upload would allow our users to upload batches of files, but it doesn’t allow them to set the meta data during upload.  Also, neither upload method allows the users to set the permissions on the file. Our Solution We looked into building a web control of some kind, but ruled that out due to security complexities (if I remember correctly).  Another option would have been using a technology like Silverlight (or Flash?), but our team didn’t have the skills necessary to build with these. So, after looking at what was technically possible, and also what skills our team had, we settled on a Windows Form application.  We also decided to deliver it to the clients via Click Once, so we would have the ability to easily update the application in the future. Lessons Learned After deploying our solution, we’ve learned a few lessons.  First, you’ll need to have the .Net Framework installed on the client computers.  We knew this, but we still ran into issues making sure our users had the proper framework version installed.  Second, we had issues with authentication.  Our issues were due to our testing domain being a separate Active Directory domain from the domain that our end users and their workstations were members of.  (See my earlier post about Clearing Saved Passwords for the fix to our problem). Our third issue was how we dealt with uploading files that were named the same.  Our application would replace the existing file with the new file, which is the way we expected it to work.  However, our users wanted to upload weekly reports, named the same as the previous week.  We solved this by using folders within the document library to keep the sets of reports separate from previous weeks. One last thing to consider before implementing a solution like this, is what browsers and platforms your users will be working from.  We only needed to support IE and Windows, which works fine.  However, if you need to support Firefox, there are add-ons that allow Click Once to work with Firefox.  This is still a Windows only solution though.  In order to support Macs, you’d have to focus on either browser techniques (AJAX?) or Silverlight/Flash. Summary Our users are happy with the Click Once app.  It allowed them to move all of their content to our SharePoint site in under a couple hours, which they were thrilled with.  We’re happy because we can easily deploy updates, our development time was small, and we met all of our business requirements.

  • MVVM Light Toolkit V3 SP1 for Windows Phone 7

    - by Laurent Bugnion
    He he I start to sound like Microsoft… Anyway… I just released a service pack (SP1) for MVVM Light Toolkit V3. Why? Well mostly because I worked a bit more with the Windows Phone 7 tools that were released at MIX0, and I noticed a few things that could be better in the Windows Phone 7 template. Also, I only found out at MIX that you can actually install custom project templates for Visual Studio Express. For some reason I thought it was not possible. The best way to solve these issues is through a service pack, which consists of a few zip files. Simply follow the instructions on the “Installing Manually” page. You can go ahead and overwrite the files that were installed with V3, all the file structure and names are exactly the same. What? So what do you get in this service pack that was not already in V3? (for more info about what’s new in V3, check the What’s New page). Project and Item templates for Visual Studio 10 Express (phone edition). Unzip these files in your “My Documents” folder, and you can now create a new MVVM Light application in the WinPhone7 version of Visual Studio 2010 Express. Signed assemblies: All the assemblies are now signed, which is a requirement in certain build configurations. XML documentation files: Thanks to Matt Casto for pinging me and reminding me that I had forgotten to include them (doh). New and improved Windows Phone 7 assemblies and templates: This one deserves its own section (see below). What was wrong with the old Silverlight 3 assemblies in Windows Phone 7 projects? It was kind of weird. Functionality wise, it was working just right. However, if you noticed, the EventToCommand behavior was not visible in the Assets tab of Expression Blend, under Behaviors, where it should normally have been. The reason was that even though the Windows Phone 7 is using Silverlight 3, the System.Windows.Interactivity that Blend was expecting is the version that is normally used in Silverlight 4. Yeah, I know, it’s weird. This led me to create a specific version of these assemblies for the phone. The assemblies are located into C:\Program Files\Laurent Bugnion (GalaSoft)\Mvvm Light Toolkit\Binaries\WP7. There are 3 DLLs: GalaSoft.MvvmLight.WP7.dll with RelayCommand, Messenger and ViewModelBase GalaSoft.MvvmLight.Extras.WP7.dll with EventToCommand and DispatcherHelper System.Windows.Interactivity.dll which is the same DLL installed in the Blend SDK, and which is needed for the EventToCommand behavior to work. Happy coding! That’s all! Download and install the service pack according to the instructions on the Installation page, and create your first MVVM Light application for the phone (a blog post will follow later with more details).   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

    Today i played a little bit with IFeature-sequences and piping data. The result was a calculator of the bounding box around all features in a feature class. Maybe a little bit dirty, but for learning was it OK. ;-) open System;; #I "C:\Program Files\ArcGIS\DotNet";; #r "ESRI.ArcGIS.System.dll";; #r "ESRI.ArcGIS.DataSourcesGDB.dll";; #r "ESRI.ArcGIS.Geodatabase.dll";; #r "ESRI.ArcGIS.Geometry.dll";; open ESRI.ArcGIS.esriSystem;; open ESRI.ArcGIS.DataSourcesGDB;; open ESRI.ArcGIS.Geodatabase;; open ESRI.ArcGIS.Geometry; let aoInitialize = new AoInitializeClass();; let status = aoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeArcEditor);; let workspacefactory = new SdeWorkspaceFactoryClass();; let connection = "SERVER=okul;DATABASE=p;VERSION=sde.default;INSTANCE=sde:sqlserver:okul;USER=s;PASSWORD=g";; let workspace = workspacefactory.OpenFromString(connection, 0);; let featureWorkspace = (box workspace) :?> IFeatureWorkspace;; let featureClass = featureWorkspace.OpenFeatureClass("Praxair.SFG.BP_L_ROHR");; let queryFilter = new QueryFilterClass();; let featureCursor = featureClass.Search(queryFilter, true);; let featureCursorSeq (featureCursor : IFeatureCursor) = let actualFeature = ref (featureCursor.NextFeature()) seq { while (!actualFeature) <> null do yield actualFeature do actualFeature := featureCursor.NextFeature() };; let min x y = if x < y then x else y;; let max x y = if x > y then x else y;; let info s (x : IEnvelope) = printfn "%s xMin:{%f} xMax: {%f} yMin:{%f} yMax: {%f}" s x.XMin x.XMax x.YMin x.YMax;; let con (env1 : IEnvelope) (env2 : IEnvelope) = let env = (new EnvelopeClass()) :> IEnvelope env.XMin <- min env1.XMin env2.XMin env.XMax <- max env1.XMax env2.XMax env.YMin <- min env1.YMin env2.YMin env.YMax <- max env1.YMax env2.YMax info "Intermediate" env env;; let feature = featureClass.GetFeature(100);; let ext = feature.Extent;; let BoundingBox featureClassName = let featureClass = featureWorkspace.OpenFeatureClass(featureClassName) let queryFilter = new QueryFilterClass() let featureCursor = featureClass.Search(queryFilter, true) let featureCursorSeq (featureCursor : IFeatureCursor) = let actualFeature = ref (featureCursor.NextFeature()) seq { while (!actualFeature) <> null do yield actualFeature do actualFeature := featureCursor.NextFeature() } featureCursorSeq featureCursor |> Seq.map (fun feature -> (!feature).Extent) |> Seq.fold (fun (acc : IEnvelope) a -> info "Intermediate" acc (con acc a)) ext ;; let boundingBox = BoundingBox "Praxair.SFG.BP_L_ROHR";; info "Ende-Info:" boundingBox;;

  • MAXDOP in SQL Azure

    - by Herve Roggero
    In my search of better understanding the scalability options of SQL Azure I stumbled on an interesting aspect: Query Hints in SQL Azure. More specifically, the MAXDOP hint. A few years ago I did a lot of analysis on this query hint (see article on SQL Server Central:  http://www.sqlservercentral.com/articles/Configuring/managingmaxdegreeofparallelism/1029/).  Here is a quick synopsis of MAXDOP: It is a query hint you use when issuing a SQL statement that provides you control with how many processors SQL Server will use to execute the query. For complex queries with lots of I/O requirements, more CPUs can mean faster parallel searches. However the impact can be drastic on other running threads/processes. If your query takes all available processors at 100% for 5 minutes... guess what... nothing else works. The bottom line is that more is not always better. The use of MAXDOP is more art than science... and a whole lot of testing; it depends on two things: the underlying hardware architecture and the application design. So there isn't a magic number that will work for everyone... except 1... :) Let me explain. The rules of engagements are different. SQL Azure is about sharing. Yep... you are forced to nice with your neighbors.  To achieve this goal SQL Azure sets the MAXDOP to 1 by default, and ignores the use of the MAXDOP hint altogether. That means that all you queries will use one and only one processor.  It really isn't such a bad thing however. Keep in mind that in some of the largest SQL Server implementations MAXDOP is usually also set to 1. It is a well known configuration setting for large scale implementations. The reason is precisely to prevent rogue statements (like a SELECT * FROM HISTORY) from bringing down your systems (like a report that should have been running on a different in the first place) and to avoid the overhead generated by executing too many parallel queries that could cause internal memory management nightmares to the host Operating System. Is summary, forcing the MAXDOP to 1 in SQL Azure makes sense; it ensures that your database will continue to function normally even if one of the other tenants on the same server is running massive queries that would otherwise bring you down. Last but not least, keep in mind as well that when you test your database code for performance on-premise, make sure to set the DOP to 1 on your SQL Server databases to simulate SQL Azure conditions.

  • Microsoft Test Manager error in displaying test steps caused by malware

    - by terje
    Sometimes the tool is blamed for errors which are not the fault of the tool – this is one such story.  It was however, not so easy to get to the bottom of it, so I hope sharing this story can help some others. One of our test developers started to get this message inside the test steps part of a test case in the MTM. saying “Could not load file or assembly ‘0 bytes from System, Version=4.0.0.0,……..” The same error came up inside Visual Studio when we opened a test case there. Then we noted a similar error on another piece of software – this error: A System.BadImageFormatException, and same message as above, but just for framework 2.0. We found this  description which pointed to a malware problem (See bottom of that post), that is a fake anti-spyware program called “Additional Guard”.  We checked the computer in question using Malwarebytes Anti-Malware tool.  It found and cleaned out 753 registry keys!!  After this cleanup operation the error was gone.  This is a great tool !  The “Additional Guard” program had been inadvertently installed, and then uninstalled afterwards, but the corrupted keys were of course not removed.  We also noted that this computer had full corporate virus scanning and malware protection, but still this nasty little thing still slipped through.

  • A BYOD World in Mobile Enterprise Brings the Need to Adapt

    - by Webgui
    Yesterday brought a lot of news coverage that Cisco has stopped funding and planning its Cius enterprise-grade tablet.  Citing “market transitions” in which an increasing number of people b ring their own smartphones and tablets to work, Cisco General Manager OJ Winge said in a post on the company's official blog that “Cisco will no longer invest in the Cisco Cius tablet form factor, and no further enhancements will be made to the current Cius endpoint beyond what’s available today.”  Employees are “bringing their preferences to work” and collaboration “has to happen beyond a walled garden,” he said.The blog post also cited a recently released Cisco study which found that 95% of organizations surveyed allow employee-owned devices in some way, shape or form in the office, and, 36% of surveyed enterprises provide full support for employee-owned devices.   How is Cisco planning to move forward to adapt to this changing business environment?  Instead of focusing on tablets for enterprise customers, Cisco will instead "double down" on software that works across a variety of operating systems and smart phones and tablets, Winge said.See the post from the Cisco blog here - http://blogs.cisco.com/collaboration/empowering-choice-in-collaboration/ We at Gizmox recognize this need to adapt to the changing environment.  Our Enterprise Mobile solution is designed and built for that post-PC, BYOD business world.  We recognized the importance of providing a cross-platform solution that can easily target different devices and operating systems. We went with a web-based mobile application approach in order to achieve that and we decided to go with the new open web standard - HTML5.Our solution however provides both client and the server side programming and its uniqueness is that it allows those cross-platform HTML5 mobile applications while developing within Visual Studio using classic visual form based development. As a result, .NET developers can build secure, efficient, data-centric enterprise mobile application for cross platform mobile devices with their existing skills and tools.  See our new video about our EnterpriseMobile solution Enterprise applications today need to work on all devices, across different platforms and OS’s.  It’s just a fact of life.  How about you – do you bring your own device to work?  What’s your company’s BYOD policy?

  • 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

  • WSS 3.0/MOSS 2007 Active Directory Forms Based Authentication PeoplePicker no users found

    - by John Haigh
    WSS 3.0/MOSS 2007 Active Directory Forms Based Authentication PeoplePicker no users found After finding these steps online from http://dattard.blogspot.com/2008/11/active-directory-forms-based.html in order to setup Active Directory Forms Based Authentication I was all set to complete this task, except for one problem. These steps are missing one very important vital step in order for FBA to work with Active Directory. A supplement to step 3 before granting access in step 5 through the people picker. You need to specify the Active Directory Provider Name to the people picker, otherwise you will not be able specify users through the Policy for Web Application. <PeoplePickerWildcards>       <clear />          <add key="ADMembershipProvider" value="%" />     </PeoplePickerWildcards> Recently we needed to use Forms Based Authentication with Active Directory from an Extranet. This is how we got it to work. 1. Extend the Web Application Instead of tweaking the internal web app, Extend the web application you want to expose to the Extranet, giving it the required host headers etc. 2. Configure SharePoint Central Admin to use FBA for the "new" Web Applications Login to SharePoint Central Admin Go to Application Management / Application Security / Authentication Providers and Change the Web Application to the one which needs to be configured for Forms Based Authentication Click zone / default, change authentication type to forms and enter ActiveDirectoryMemebershipProvider under membership provider name ( for example , "ADMembershipProvider") and save this change 3. Update the web.config of SharePoint Central admin site under configuration node <connectionStrings> <add name="ADConnectionString" connectionString="LDAP://DynamicsAX.local/CN=Users,DC=DynamicsAX,DC=local /> </connectionStrings> under system.web node <membership defaultProvider="ADMembershipProvider"> <providers> <add name="ADMembershipProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider,System.Web,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ADConnectionString" connectionUsername="xxx" connectionPassword="yyy" enableSearchMethods="true" attributeMapUsername="sAMAccountName"/> </providers> </membership> 4.Update the web.config of SharePoint Web application Repeat step 3 for the web.config of the SharePoint webapplication to be configured for Forms Based Authentication Change the authentication in web.config to <authentication mode="Forms"> <forms loginUrl="/_layouts/login.aspx"></forms> </authentication> 5. Grant Access on the extended Web Application Your extranet web application is now configured to use FBA. However, until users, who will be accessing the site via FBA, are given permissions for the site, it will be inaccessible to them. To get started, open your browser and navigate to your farm’s Central Administration site. Click on Application Management and then click on Policy for Web Application. Make sure that you are working on the extranet web application. Do the following steps: Click on Add Users. In the Zones drop down, select the appropriate Extranet zone. IMPORTANT: If you select the incorrect zone, you may not be able to resolve user names. Hence, the zone you select must match the zone of the web application that is configured to use FBA. Click the Next button. In the Users edit box, type the name of the FBA user whom you wish to have full control for the site. Click the Resolve link next to the Users edit box. If the web application's FBA information has been configured correctly, the name will resolve and become underlined. Check the Full Control checkbox. Click the Finish button.

  • BDD IS Different to TDD

    - by Liam McLennan
    One of this morning’s sessions at Alt.NET 2010 discussed BDD. Charlie Pool expressed the opinion, which I have heard many times, that BDD is just a description of TDD done properly. For me, the core principles of BDD are: expressing behaviour in terms that show the value to the system actors Expressing behaviours / scenarios in a format that clearly separates the context, the action and the observations. If we go back to Kent Beck’s TDD book neither of these elements are mentioned as being core to TDD. BDD is an evolution of TDD. It is a specialisation of TDD, but it is not the same as TDD. Discussing BDD, and building specialised tools for BDD, is valuable even though the difference between BDD and TDD is subtle. Further, the existence of BDD does not mean that TDD is obsolete or invalidated.

  • Getting Started With Sinatra

    - by Liam McLennan
    Sinatra is a Ruby DSL for building web applications. It is distinguished from its peers by its minimalism. Here is hello world in Sinatra: require 'rubygems' require 'sinatra' get '/hi' do "Hello World!" end A haml view is rendered by: def '/' haml :name_of_your_view end Haml is also new to me. It is a ruby-based view engine that uses significant white space to avoid having to close tags. A hello world web page in haml might look like: %html %head %title Hello World %body %div Hello World You see how the structure is communicated using indentation instead of opening and closing tags. It makes views more concise and easier to read. Based on my syntax highlighter for Gherkin I have started to build a sinatra web application that publishes syntax highlighted gherkin feature files. I have found that there is a need to have features online so that customers can access them, and so that they can be linked to project management tools like Jira, Mingle, trac etc. The first thing I want my application to be able to do is display a list of the features that it knows about. This will happen when a user requests the root of the application. Here is my sinatra handler: get '/' do feature_service = Finding::FeatureService.new(Finding::FeatureFileFinder.new, Finding::FeatureReader.new) @features = feature_service.features(settings.feature_path, settings.feature_extensions) haml :index end The handler and the view are in the same scope so the @features variable will be available in the view. This is the same way that rails passes data between actions and views. The view to render the result is: %h2 Features %ul - @features.each do |feature| %li %a{:href => "/feature/#{feature.name}"}= feature.name Clearly this is not a complete web page. I am using a layout to provide the basic html page structure. This view renders an <li> for each feature, with a link to /feature/#{feature.name}. Here is what the page looks like: When the user clicks on one of the links I want to display the contents of that feature file. The required handler is: get '/feature/:feature' do @feature_name = params[:feature] feature_service = Finding::FeatureService.new(Finding::FeatureFileFinder.new, Finding::FeatureReader.new) # TODO replace with feature_service.feature(name) @feature = feature_service.features(settings.feature_path, settings.feature_extensions).find do |feature| feature.name == @feature_name end haml :feature end and the view: %h2= @feature.name %pre{:class => "brush: gherkin"}= @feature.description %div= partial :_back_to_index %script{:type => "text/javascript", :src => "/scripts/shCore.js"} %script{:type => "text/javascript", :src => "/scripts/shBrushGherkin.js"} %script{:type => "text/javascript" } SyntaxHighlighter.all(); Now when I click on the Search link I get a nicely formatted feature file: If you would like see the full source it is available on bitbucket.
