  • Multiple Monitors

    - by mroberts
    At my workplace .Net developers get pretty much the same equipment. A decent Dell workstation / Desktop, mine is a Dell Precision 390. One dual core 2.40 GHz. Eight GB RAM. Windows 7 Enterprise 64-bit. Two Dell 20.1 Monitors. I'm happy with this.  The machine is about 3 years old but still runs with some decent speed. New developers are getting a Dell workstation with dual quad processors. I just put in a request for myself and three other developers for an upgraded video card and two additional monitors, for a total of four monitors per person.  We suggested this card, BTW, mainly for the cost.  The move from one monitor to two was fantastic (one might even say life (or work) changing) and truly did increase productivity. Now what about going from 2 monitors to 4?  I'm sure the change is not as dramatic as one to two, but I can't help but to think four monitors is better than two.  But if four is better than two, should we have asked for six?!? Also what about mixing monitor types?  Right now my monitors are the older square type vs. wide-screen.  It's been rumored that we will be getting monitors out of current stock and they will be 22 inch wide-screens.  I understand this, recession and all.  2-20 inch square monitors with 2-22 inch wide-screen monitors...hmmmmm.  I'm thinking I'd rather get 2 additional 17 inch square monitors to put on each side of my 20's. Also, a question was raised about the layout of four monitors. By default, my thought was I'll just put them all on my desk, kinda in a line. I've heard others say they want to stack them in a 2 x 2 square. BTW, loving multi monitor support in Visual studio 2010! I’d love some comments on your experience with one, two, four, or however many monitors from a developers perspective.

  • Slides and Code from my Silverlight MVVM Talk at DevConnections

    - by dwahlin
    I had a great time at the DevConnections conference in Las Vegas this year where Visual Studio 2010 and Silverlight 4 were launched. While at the conference I had the opportunity to give a full-day Silverlight workshop as well as 4 different talks and met a lot of people developing applications in Silverlight. I also had a chance to appear on a live broadcast of Channel 9 with John Papa, Ward Bell and Shawn Wildermuth, record a video with Rick Strahl covering jQuery versus Silverlight and record a few podcasts on Silverlight and ASP.NET MVC 2.  It was a really busy 4 days but I had a lot of fun chatting with people and hearing about different business problems they were solving with ASP.NET and/or Silverlight. Thanks to everyone who attended my sessions and took the time to ask questions and stop by to talk one-on-one. One of the talks I gave covered the Model-View-ViewModel pattern and how it can be used to build architecturally sound applications. Topics covered in the talk included: Understanding the MVVM pattern Benefits of the MVVM pattern Creating a ViewModel class Implementing INotifyPropertyChanged in a ViewModelBase class Binding a ViewModel declaratively in XAML Binding a ViewModel with code ICommand and ButtonBase commanding support in Silverlight 4 Using InvokeCommandBehavior to handle additional commanding needs Working with ViewModels and Sample Data in Blend Messaging support with EventBus classes, EventAggregator and Messenger My personal take on code in a code-beside file (I’m all in favor of it when used appropriately for message boxes, child windows, animations, etc.) One of the samples I showed in the talk was intended to teach all of the concepts mentioned above while keeping things as simple as possible.  The sample demonstrates quite a few things you can do with Silverlight and the MVVM pattern so check it out and feel free to leave feedback about things you like, things you’d do differently or anything else. MVVM is simply a pattern, not a way of life so there are many different ways to implement it. If you’re new to the subject of MVVM check out the following resources. I wish this talk would’ve been recorded (especially since my live and canned demos all worked :-)) but these resources will help get you going quickly.

  • SQL SERVER – 4 Tips for ETL Software IDE Developers

    - by pinaldave
    In a previous blog, I introduced the notion of Semantic Types. To an end-user, a seamlessly integrated semantic typing engine significantly increases the ease of use of an ETL IDE (integrated development environment, or developer studio). This led me to think about other ease-of-use issues I have encountered while building ETL applications. When I get stumped while programming, I find myself asking the variations on these questions: “How do I…?” “Now what?” “Why isn’t this working?” “Why do I have to redo the work I just did?” It seems to me that a good ETL IDE will anticipate these questions and seek to answer them before they are even asked. So here are my tips to help software vendors build developer IDEs that actually make development easier. How do I…? While developing an ETL application, have you ever asked yourself: “How do I set up the connection to my SQL Server database?”,“How do I import my table definitions from Access?”, etc. An easy answer might be “read the manual” but sometimes product manuals are not robust or easily accessible. So, integrating robust how-to instructions directly into your ETLstudio would help users get the information they need at the time they need it. Now what? IDEs in general know where you last clicked or performed an action using an input device such as a keyboard; so they should be able to reasonably predict the design context you are in and suggest the next steps accordingly. Context-sensitive suggestions based on the state of the user’s work will help users move forward in ETL application development. Why isn’t this working? Or why do I have to wait till I compile to be told about a critical design issue? If an ETL IDE is smart enough to signal to users what in their design structures is left to be completed or has been completed incorrectly, then the developer can spend much less time in the designàcompileàerror-correct loop. Just-in-time validation helps users detect and correct programming errors earlier in the ETL development life cycle. Why do I have to redo the work I just did? In ETL development, schemas, transformation rules, connectivity objects, etc., can be reused in various situations. Using mouse-clicks to build and manage libraries of reusable design objects implies that the application development effort should decrease over time and as the library acquires more objects. I met a great company at SQL Pass that is trying to address many of these usability issues. Check them out at www.expressor-software.com. What other ease-of-use suggestions do you have for ETL software vendors? Please post your valuable comments. ?Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Best Practices, Pinal Dave, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: ETL

  • What Every Developer Should Know About MSI Components

    - by Alois Kraus
    Hopefully nothing. But if you have to do more than simple XCopy deployment and you need to support updates, upgrades and perhaps side by side scenarios there is no way around MSI. You can create Msi files with a Visual Studio Setup project which is severely limited or you can use the Windows Installer Toolset. I cannot talk about WIX with my German colleagues because WIX has a very special meaning. It is funny to always use the long name when I talk about deployment possibilities. Alternatively you can buy commercial tools which help you to author Msi files but I am not sure how good they are. Given enough pain with existing solutions you can also learn the MSI Apis and create your own packaging solution. If I were you I would use either a commercial visual tool when you do easy deployments or use the free Windows Installer Toolset. Once you know the WIX schema you can create well formed wix xml files easily with any editor. Then you can “compile” from the wxs files your Msi package. Recently I had the “pleasure” to get my hands dirty with C++ (again) and the MSI technology. Installation is a complex topic but after several month of digging into arcane MSI issues I can safely say that there should exist an easier way to install and update files as today. I am not alone with this statement as John Robbins (creator of the cool tool Paraffin) states: “.. It's a brittle and scary API in Windows …”. To help other people struggling with installation issues I present you the advice I (and others) found useful and what will happen if you ignore this advice. What is a MSI file? A MSI file is basically a database with tables which reference each other to control how your un/installation should work. The basic idea is that you declare via these tables what you want to install and MSI controls the how to get your stuff onto or off your machine. Your “stuff” consists usually of files, registry keys, shortcuts and environment variables. Therefore the most important tables are File, Registry, Environment and Shortcut table which define what will be un/installed. The key to master MSI is that every resource (file, registry key ,…) is associated with a MSI component. The actual payload consists of compressed files in the CAB format which can either be embedded into the MSI file or reside beside the MSI file or in a subdirectory below it. To examine MSI files you need Orca a free MSI editor provided by MS. There is also another free editor called Super Orca which does support diffs between MSI and it does not lock the MSI files. But since Orca comes with a shell extension I tend to use only Orca because it is so easy to right click on a MSI file and open it with this tool. How Do I Install It? Double click it. This does work for fresh installations as well as major upgrades. Updates need to be installed via the command line via msiexec /i <msi> REINSTALL=ALL REINSTALLMODE=vomus   This tells the installer to reinstall all already installed features (new features will NOT be installed). The reinstallmode letters do force an overwrite of the old cached package in the %WINDIR%\Installer folder. All files, shortcuts and registry keys are redeployed if they are missing or need to be replaced with a newer version. When things did go really wrong and you want to overwrite everything unconditionally use REINSTALLMODE=vamus. How To Enable MSI Logs? You can download a MSI from Microsoft which installs some registry keys to enable full MSI logging. The log files can be found in your %TEMP% folder and are called MSIxxxx.log. Alternatively you can add to your msiexec command line the option msiexec …. /l*vx <LogFileName> Personally I find it rather strange that * does not mean full logging. To really get all logs I need to add v and x which is documented in the msiexec help but I still find this behavior unintuitive. What are MSI components? The whole MSI logic is bound to the concept of MSI components. Nearly every msi table has a Component column which binds an installable resource to a component. Below are the screenshots of the FeatureComponents and Component table of an example MSI. The Feature table defines basically the feature hierarchy.  To find out what belongs to a feature you need to look at the FeatureComponents table where for each feature the components are listed which will be installed when a feature is installed. The MSI components are defined in the  Component table. This table has as first column the component name and as second column the component id which is a GUID. All resources you want to install belong to a MSI component. Therefore nearly all MSI tables have a Component_ column which contains the component name. If you look e.g. a the File table you see that every file belongs to a component which is true for all other tables which install resources. The component table is the glue between all other tables which contain the resources you want to install. So far so easy. Why is MSI then so complex? Most MSI problems arise from the fact that you did violate a MSI component rule in one or the other way. When you install a feature the reference count for all components belonging to this feature will increase by one. If your component is installed by more than one feature it will get a higher refcount. When you uninstall a feature its refcount will drop by one. Interesting things happen if the component reference count reaches zero: Then all associated resources will be deleted. That looks like a reasonable thing and it is. What it makes complex are the strange component rules you have to follow. Below are some important component rules from the Tao of the Windows Installer … Rule 16: Follow Component Rules Components are a very important part of the Installer technology. They are the means whereby the Installer manages the resources that make up your application. The SDK provides the following guidelines for creating components in your package: Never create two components that install a resource under the same name and target location. If a resource must be duplicated in multiple components, change its name or target location in each component. This rule should be applied across applications, products, product versions, and companies. Two components must not have the same key path file. This is a consequence of the previous rule. The key path value points to a particular file or folder belonging to the component that the installer uses to detect the component. If two components had the same key path file, the installer would be unable to distinguish which component is installed. Two components however may share a key path folder. Do not create a version of a component that is incompatible with all previous versions of the component. This rule should be applied across applications, products, product versions, and companies. Do not create components containing resources that will need to be installed into more than one directory on the user’s system. The installer installs all of the resources in a component into the same directory. It is not possible to install some resources into subdirectories. Do not include more than one COM server per component. If a component contains a COM server, this must be the key path for the component. Do not specify more than one file per component as a target for the Start menu or a Desktop shortcut. … And these rules do not even talk about component ids, update packages and upgrades which you need to understand as well. Lets suppose you install two MSIs (MSI1 and MSI2) which have the same ComponentId but different component names. Both do install the same file. What will happen when you uninstall MSI2?   Hm the file should stay there. But the component names are different. Yes and yes. But MSI uses not use the component name as key for the refcount. Instead the ComponentId column of the Component table which contains a GUID is used as identifier under which the refcount is stored. The components Comp1 and Comp2 are identical from the MSI perspective. After the installation of both MSIs the Component with the Id {100000….} has a refcount of two. After uninstallation of one MSI there is still a refcount of one which drops to zero just as expected when we uninstall the last msi. Then the file which was the same for both MSIs is deleted. You should remember that MSI keeps a refcount across MSIs for components with the same component id. MSI does manage components not the resources you did install. The resources associated with a component are then and only then deleted when the refcount of the component reaches zero.   The dependencies between features, components and resources can be described as relations. m,k are numbers >= 1, n can be 0. Inside a MSI the following relations are valid Feature    1  –> n Components Component    1 –> m Features Component      1  –>  k Resources These relations express that one feature can install several components and features can share components between them. Every (meaningful) component will install at least one resource which means that its name (primary key to stay in database speak) does occur in some other table in the Component column as value which installs some resource. Lets make it clear with an example. We want to install with the feature MainFeature some files a registry key and a shortcut. We can then create components Comp1..3 which are referenced by the resources defined in the corresponding tables.   Feature Component Registry File Shortcuts MainFeature Comp1 RegistryKey1     MainFeature Comp2   File.txt   MainFeature Comp3   File2.txt Shortcut to File2.txt   It is illegal that the same resource is part of more than one component since this would break the refcount mechanism. Lets illustrate this:            Feature ComponentId Resource Reference Count Feature1 {1000-…} File1.txt 1 Feature2 {2000-….} File1.txt 1 The installation part works well but what happens when you uninstall Feature2? Component {20000…} gets a refcount of zero where MSI deletes all resources belonging to this component. In this case File1.txt will be deleted. But Feature1 still has another component {10000…} with a refcount of one which means that the file was deleted too early. You just have ruined your installation. To fix it you then need to click on the Repair button under Add/Remove Programs to let MSI reinstall any missing registry keys, files or shortcuts. The vigilant reader might has noticed that there is more in the Component table. Beside its name and GUID it has also an installation directory, attributes and a KeyPath. The KeyPath is a reference to a file or registry key which is used to detect if the component is already installed. This becomes important when you repair or uninstall a component. To find out if the component is already installed MSI checks if the registry key or file referenced by the KeyPath property does exist. When it does not exist it assumes that it was either already uninstalled (can lead to problems during uninstall) or that it is already installed and all is fine. Why is this detail so important? Lets put all files into one component. The KeyPath should be then one of the files of your component to check if it was installed or not. When your installation becomes corrupt because a file was deleted you cannot repair it with the Repair button under Add/Remove Programs because MSI checks the component integrity via the Resource referenced by its KeyPath. As long as you did not delete the KeyPath file MSI thinks all resources with your component are installed and never executes any repair action. You get even more trouble when you try to remove files during an upgrade (you cannot remove files during an update) from your super component which contains all files. The only way out and therefore best practice is to assign for every resource you want to install an extra component. This ensures painless updatability and repairs and you have much less effort to remove specific files during an upgrade. In effect you get this best practice relation Feature 1  –> n Components Component   1  –>  1 Resources MSI Component Rules Rule 1 – One component per resource Every resource you want to install (file, registry key, value, environment value, shortcut, directory, …) must get its own component which does never change between versions as long as the install location is the same. Penalty If you add more than one resources to a component you will break the repair capability of MSI because the KeyPath is used to check if the component needs repair. MSI ComponentId Files MSI 1.0 {1000} File1-5 MSI 2.0 {2000} File2-5 You want to remove File1 in version 2.0 of your MSI. Since you want to keep the other files you create a new component and add them there. MSI will delete all files if the component refcount of {1000} drops to zero. The files you want to keep are added to the new component {2000}. Ok that does work if your upgrade does uninstall the old MSI first. This will cause the refcount of all previously installed components to reach zero which means that all files present in version 1.0 are deleted. But there is a faster way to perform your upgrade by first installing your new MSI and then remove the old one.  If you choose this upgrade path then you will loose File1-5 after your upgrade and not only File1 as intended by your new component design.   Rule 2 – Only add, never remove resources from a component If you did follow rule 1 you will not need Rule 2. You can add in a patch more resources to one component. That is ok. But you can never remove anything from it. There are tricky ways around that but I do not want to encourage bad component design. Penalty Lets assume you have 2 MSI files which install under the same component one file   MSI1 MSI2 {1000} - ComponentId {1000} – ComponentId File1.txt File2.txt   When you install and uninstall both MSIs you will end up with an installation where either File1 or File2 will be left. Why? It seems that MSI does not store the resources associated with each component in its internal database. Instead Windows will simply query the MSI that is currently uninstalled for all resources belonging to this component. Since it will find only one file and not two it will only uninstall one file. That is the main reason why you never can remove resources from a component!   Rule 3 Never Remove A Component From an Update MSI. This is the same as if you change the GUID of a component by accident for your new update package. The resulting update package will not contain all components from the previously installed package. Penalty When you remove a component from a feature MSI will set the feature state during update to Advertised and log a warning message into its log file when you did enable MSI logging. SELMGR: ComponentId '{2DCEA1BA-3E27-E222-484C-D0D66AEA4F62}' is registered to feature 'xxxxxxx, but is not present in the Component table.  Removal of components from a feature is not supported! MSI (c) (24:44) [07:53:13:436]: SELMGR: Removal of a component from a feature is not supported Advertised means that MSI treats all components of this feature as not installed. As a consequence during uninstall nothing will be removed since it is not installed! This is not only bad because uninstall does no longer work but this feature will also not get the required patches. All other features which have followed component versioning rules for update packages will be updated but the one faulty feature will not. This results in very hard to find bugs why an update was only partially successful. Things got better with Windows Installer 4.5 but you cannot rely on that nobody will use an older installer. It is a good idea to add to your update msiexec call MSIENFORCEUPGRADECOMPONENTRULES=1 which will abort the installation if you did violate this rule.

  • [MISC GEEKERY] Lucid Lynx to Come Loaded with Ubuntu One Music Store

    - by Vivek
    Ubuntu 10.04 (code name Lucid Lynx) will come loaded with the Ubuntu One music store. Rhythmbox will have the Ubuntu One music store integrated in it. It’ll also allow users to download purchased music to their local machine. Ubuntu One Music Store Users will be able to access Ubuntu One music store from the sidebar of Rhythmbox. The music store is a web page that opens in the Rhythmbox player. There are albums listed on the home page of the Ubuntu One music store page. Ubuntu One music store is powered by 7digital, which is a leading digital B2B media delivery company based in London and operating globally. Canonical, the company behind Ubuntu, has partnered with 7digital to bring the music store to it’s users, integrating it with Rhythmbox and it’s cloud storage service UbuntuOne which was launched last year. The home screen of the Ubuntu One music store displays popular albums and functionality to browse and search. You can search for Artists, Tracks, Albums, or a combination of all three. Users will also be able to browse the store alphabetically, or based on different music genres. Once you select a specific artist, all their available albums are arranged in a grid. Once an album is selected, you’ll will be able to download specific songs or the whole album. You’ll also be allowed to preview different songs for 60 seconds. You’ll be able to buy tracks using a credit card or with PayPal. The purchased tracks will be visible under Library \ Purchased from Ubuntu One. The downloaded tracks are also synced with your UbuntuOne account. This means that you’ll be able to access your tracks from any where on the web. The default UbuntuOne account comes with 2 GB free storage, however, you can also purchase additional space if you need it.   All the music is in mp3 format which is not supported by default in Ubuntu. However, you can get mp3 playback functionality using GStreamer multimedia framework. Conclusion All in all the Ubuntu One music store is a positive move to enhance the user experience and also increase the popularity of Canonical in bringing Ubuntu closer to regular users. This would also provide Canonical to make some revenue in collaboration with 7digital.

  • How to add event receiver to SharePoint2010 content type programmatically

    - by ybbest
    Today , I’d like to show how to add event receiver to How to add event receiver to SharePoint2010 content type programmatically. 1. Create empty SharePoint Project and add a class called ItemContentTypeEventReceiver and make it inherit from SPItemEventReceiver and implement your logic as below public class ItemContentTypeEventReceiver : SPItemEventReceiver { private bool eventFiringEnabledStatus; public override void ItemAdded(SPItemEventProperties properties) { base.ItemAdded(properties); UpdateTitle(properties); } private void UpdateTitle(SPItemEventProperties properties) { SPListItem addedItem = properties.ListItem; string enteredTitle = addedItem["Title"] as string; addedItem["Title"] = enteredTitle + " Updated"; DisableItemEventsScope(); addedItem.Update(); EnableItemEventsScope(); } public override void ItemUpdated(SPItemEventProperties properties) { base.ItemUpdated(properties); UpdateTitle(properties); } private void DisableItemEventsScope() { eventFiringEnabledStatus = EventFiringEnabled; EventFiringEnabled = false; } private void EnableItemEventsScope() { eventFiringEnabledStatus = EventFiringEnabled; EventFiringEnabled = true; } } 2.Create a Site or Web(depending or your requirements) scoped feature and implement your feature event handler as below: public override void FeatureActivated(SPFeatureReceiverProperties properties) { SPWeb web = GetFeatureWeb(properties); //http://karinebosch.wordpress.com/walkthroughs/event-receivers-theory/ string assemblyName =  System.Reflection.Assembly.GetExecutingAssembly().FullName; const string className = "YBBEST.AddEventReceiverToContentType.ItemContentTypeEventReceiver"; SPContentType contentType= web.ContentTypes["Item"]; AddEventReceiverToContentType(className, contentType, assemblyName, SPEventReceiverType.ItemAdded, SPEventReceiverSynchronization.Asynchronous); AddEventReceiverToContentType(className, contentType, assemblyName, SPEventReceiverType.ItemUpdated, SPEventReceiverSynchronization.Asynchronous); contentType.Update(); } protected static void AddEventReceiverToContentType(string className, SPContentType contentType, string assemblyName, SPEventReceiverType eventReceiverType, SPEventReceiverSynchronization eventReceiverSynchronization) { if (className == null) throw new ArgumentNullException("className"); if (contentType == null) throw new ArgumentNullException("contentType"); if (assemblyName == null) throw new ArgumentNullException("assemblyName"); SPEventReceiverDefinition eventReceiver = contentType.EventReceivers.Add(); eventReceiver.Synchronization = eventReceiverSynchronization; eventReceiver.Type = eventReceiverType; eventReceiver.Assembly = assemblyName; eventReceiver.Class = className; eventReceiver.Update(); } 3.Deploy your solution and now you have a event receiver that attached to the Item contentType. You can download the complete source code here.You can also check how to add event receiver to a list using SharePoint event receiver item in Visual Studio2010 in my previous blog.

  • Reverse-engineer SharePoint fields, content types and list instance—Part3

    - by ybbest
    Reverse-engineer SharePoint fields, content types and list instance—Part1 Reverse-engineer SharePoint fields, content types and list instance—Part2 Reverse-engineer SharePoint fields, content types and list instance—Part3 In Part 1 and Part 2 of this series, I demonstrate how to reverse engineer SharePoint fields, content types. In this post I will cover how to include lookup fields in the content type and create list instance using these content types. Firstly, I will cover how to create list instance and bind the custom content type to the custom list. 1. Create a custom list using list Instance item in visual studio and select custom list. 2. In the feature receiver add the Department content type to Department list and remove the item content type. C# AddContentTypeToList(web, “Department”, ” Department”); private void AddContentTypeToList(SPWeb web,string listName, string contentTypeName) { SPList list = web.Lists.TryGetList(listName); list.OnQuickLaunch = true; list.ContentTypesEnabled = true; list.Update(); SPContentType employeeContentType = web.ContentTypes[contentTypeName]; list.ContentTypes.Add(employeeContentType); list.ContentTypes["Item"].Delete(); list.Update(); } Next, I will cover how to create the lookup fields. The difference between creating a normal field and lookup fields is that you need to create the lookup fields after the lists are created. This is because the lookup fields references fields from the foreign list. 1. In your solution, you need to create a feature that deploys the list before deploying the lookup fields. 2. You need to write the following code in the feature receiver to add the lookup columns in the ContentType. C# //add the lookup fields SPFieldLookup departmentField = EnsureLookupField(currentWeb, “YBBESTDepartment”, currentWeb.Lists["DepartmentList"].ID, “Title”); //add to the content types SPContentType employeeContentType = currentWeb.ContentTypes["Employee"]; //Add the lookup fields as SPFieldLink employeeContentType.FieldLinks.Add(new SPFieldLink(departmentField)); employeeContentType.Update(true); private static SPFieldLookup EnsureLookupField(SPWeb currentWeb, String sFieldName, Guid LookupListID, String sLookupField) { //add the lookup fields SPFieldLookup lookupField = null; try { lookupField = currentWeb.Fields[sFieldName] as SPFieldLookup; } catch (Exception e) { } if (lookupField == null) { currentWeb.Fields.AddLookup(sFieldName, LookupListID, true); currentWeb.Update(); lookupField = currentWeb.Fields[sFieldName] as SPFieldLookup; lookupField.LookupField = sLookupField; lookupField.Group = “YBBEST”; lookupField.Required = true; lookupField.Update(); } return lookupField; }

  • How to update all the SSIS packages&rsquo; Connection Managers in a BIDS project with PowerShell

    - by Luca Zavarella
    During the development of a BI solution, we all know that 80% of the time is spent during the ETL (Extract, Transform, Load) phase. If you use the BI Stack Tool provided by Microsoft SQL Server, this step is accomplished by the development of n Integration Services (SSIS) packages. In general, the number of packages made ??in the ETL phase for a non-trivial solution of BI is quite significant. An SSIS package, therefore, extracts data from a source, it "hammers" :) the data and then transfers it to a specific destination. Very often it happens that the connection to the source data is the same for all packages. Using Integration Services, this results in having the same Connection Manager (perhaps with the same name) for all packages: The source data of my BI solution comes from an Helper database (HLP), then, for each package tha import this data, I have the HLP Connection Manager (the use of a Shared Data Source is not recommended, because the Connection String is wired and therefore you have to open the SSIS project and use the proper wizard change it...). In order to change the HLP Connection String at runtime, we could use the Package Configuration, or we could run our packages with DTLoggedExec by Davide Mauri (a must-have if you are developing with SQL Server 2005/2008). But my need was to change all the HLP connections in all packages within the SSIS Visual Studio project, because I had to version them through Team Foundation Server (TFS). A good scribe with a lot of patience should have changed by hand all the connections by double-clicking the HLP Connection Manager of each package, and then changing the referenced server/database: Not being endowed with such virtues :) I took just a little of time to write a small script in PowerShell, using the fact that a SSIS package (a .dtsx file) is nothing but an xml file, and therefore can be changed quite easily. I'm not a guru of PowerShell, but I managed more or less to put together the following lines of code: $LeftDelimiterString = "Initial Catalog=" $RightDelimiterString = ";Provider=" $ToBeReplacedString = "AstarteToBeReplaced" $ReplacingString = "AstarteReplacing" $MainFolder = "C:\MySSISPackagesFolder" $files = get-childitem "$MainFolder" *.dtsx `       | Where-Object {!($_.PSIsContainer)} foreach ($file in $files) {       (Get-Content $file.FullName) `             | % {$_ -replace "($LeftDelimiterString)($ToBeReplacedString)($RightDelimiterString)", "`$1$ReplacingString`$3"} ` | Set-Content $file.FullName; } The script above just opens any SSIS package (.dtsx) in the supplied folder, then for each of them goes in search of the following text: Initial Catalog=AstarteToBeReplaced;Provider= and it replaces the text found with this: Initial Catalog=AstarteReplacing;Provider= I don’t enter into the details of each cmdlet used. I leave the reader to search for these details. Alternatively, you can use a specific object model exposed in some .NET assemblies provided by Integration Services, or you can use the Pacman utility: Enjoy! :) P.S. Using TFS as versioning system, before running the script I checked out the packages and, after the script executed succesfully, I checked in them.

  • Predicting Likelihood of Click with Multiple Presentations

    - by Michel Adar
    When using predictive models to predict the likelihood of an ad or a banner to be clicked on it is common to ignore the fact that the same content may have been presented in the past to the same visitor. While the error may be small if the visitors do not often see repeated content, it may be very significant for sites where visitors come repeatedly. This is a well recognized problem that usually gets handled with presentation thresholds – do not present the same content more than 6 times. Observations and measurements of visitor behavior provide evidence that something better is needed. Observations For a specific visitor, during a single session, for a banner in a not too prominent space, the second presentation of the same content is more likely to be clicked on than the first presentation. The difference can be 30% to 100% higher likelihood for the second presentation when compared to the first. That is, for example, if the first presentation has an average click rate of 1%, the second presentation may have an average CTR of between 1.3% and 2%. After the second presentation the CTR stays more or less the same for a few more presentations. The number of presentations in this plateau seems to vary by the location of the content in the page and by the visual attraction of the content. After these few presentations the CTR starts decaying with a curve that is very well approximated by an exponential decay. For example, the 13th presentation may have 90% the likelihood of the 12th, and the 14th has 90% the likelihood of the 13th. The decay constant seems also to depend on the visibility of the content. Modeling Options Now that we know the empirical data, we can propose modeling techniques that will correctly predict the likelihood of a click. Use presentation number as an input to the predictive model Probably the most straight forward approach is to add the presentation number as an input to the predictive model. While this is certainly a simple solution, it carries with it several problems, among them: If the model learns on each case, repeated non-clicks for the same content will reinforce the belief of the model on the non-clicker disproportionately. That is, the weight of a person that does not click for 200 presentations of an offer may be the same as 100 other people that on average click on the second presentation. The effect of the presentation number is not a customer characteristic or a piece of contextual data about the interaction with the customer, but it is contextual data about the content presented. Models tend to underestimate the effect of the presentation number. For these reasons it is not advisable to use this approach when the average number of presentations of the same content to the same person is above 3, or when there are cases of having the presentation number be very large, in the tens or hundreds. Use presentation number as a partitioning attribute to the predictive model In this approach we essentially build a separate predictive model for each presentation number. This approach overcomes all of the problems in the previous approach, nevertheless, it can be applied only when the volume of data is large enough to have these very specific sub-models converge.

  • cocos2dx - Custom Fragment Shader and CCRenderTexture

    - by saiy2k
    I have a CCRenderTexture that is filled with a sprite when the scene is loaded, as follows, canvas = CCRenderTexture::create(this->getContentSize().width, this->getContentSize().height); canvas->setPosition(data->position); canvas->beginWithClear(0.0, 0.0, 0.0, 0); this->visit(); canvas->end(); The above code is written within a class, which derives from CCSprite (Hence this). Then, in another function applyShader(), I create a sprite named splat, from the texture of CCRenderTexture *canvas. Thus splat will contain the whole texture of canvas. Now I apply a custom fragment shader to the splat by calling the function splat->renderShader(), which will modify some small portion of the whole texture. Then I draw the modified texture back to the CCRenderTexture *canvas. Hence, applyShader() will * take a texture from CCRenderTexture, * create a sprite based on it, * apply a fragment shader to it * and draw the modified texture back to CCRenderTexture. This applyShader() will be called repetitively and its code is as follows: splat = Splat::createWithTexture(art->canvas->getSprite()->getTexture()); splat->renderShader(); art->canvas->begin(); splat->visit(); art->canvas->end(); My shader code is (nothing fancy) precision mediump float; varying vec2 v_texCoord; uniform sampler2D u_texture; uniform sampler2D u_colorRampTexture; uniform float params[5]; void main() { gl_FragColor = texture2D(u_texture, v_texCoord); return; } So, with the above code I expect the original sprite this to get rendered over and over again without any visual changes. But on each call to applyShader(), the texture is getting stretched a little and the stretched image is getting rendered. After some 10 calls, the image gets so distorted. Can someone please tell me where I am going wrong? Thanks :-) PS: All code shown here is partial, not complete code. Edit: Adding Screens Update: The problem has nothing to do with shaders it seems. It happens even when I dont call renderShader(). The actual lines of code is: splat = Splat::createWithTexture(art->canvas->getSprite()->getTexture()); splat->setPosition( ccp( art->getContentSize().width * 0.5, art->getContentSize().height * 0.5 ) ); splat->setFlipY(true); art->canvas->begin(); splat->visit(); art->canvas->end();

  • BUILD 2013 - Microsoft Set to Unveil It&rsquo;s Reinvention

    - by D'Arcy Lussier
    Originally posted on: http://geekswithblogs.net/dlussier/archive/2013/06/24/153211.aspxSome thoughts as we head into BUILD this week… This week in San Francisco Microsoft will be hosting the BUILD conference. They’ll be talking up Windows 8.1 (Windows Blue), more Azure, some Windows Phone, XBox, Office 365… actually, they told us on the original BUILD announcement site what we’d be seeing:           While looking at this, consider a recent article from The Verge that talks about the speculation of a huge shake up at Microsoft . From the article: All Things D quotes one insider as saying they're "titanic" changes, noting they might be attached to Ballmer's legacy at the company. "It’s the first time in a long time that it feels like that there will be some major shifts, including some departures," says the alleged insider. Considering Ballmer let Sinofsky go right after the Windows 8 launch, the idea of Microsoft cutting loose some executives doesn’t seem to be big news. But the next piece of the article frames things more interestingly: Ballmer is reportedly considering a new structure that would create four separate divisions: enterprise business, hardware, applications and services, and an operating systems group. This statement got me thinking…what would this new structure look like? Below is one possibility: At a recent (this year or last year, I can’t recall which) Microsoft shareholder’s meeting, Ballmer made the statement that Microsoft is now a products and services company. At the time I don’t think I really let that statement sink in. Partially because I really liked the Microsoft of my professional youth – the one that was a software and platform company. In Canada, Microsoft has been pushing three platform areas: Lync, Azure, and SQL Server. I would expect those to change moving forward as Microsoft continues to look for Partners that will help them increase their Services revenue through solutions that incorporate/are based on Azure, Office 365, Lync, and Dynamics. I also wonder if we’re not seeing a culling of partners through changes to the Microsoft Partner Program. In addition to the changing certification requirements that align more to Microsoft’s goals (i.e. There is no desktop development based MCSD, only Windows 8 Store Apps), competencies that partners can qualify for are being merged, requirements changed, and licenses provided reduced. Ballmer warned as much at the last WPC though that they were looking for partners who were “all in” with Microsoft, and these programs seem to support that sentiment. Heading into BUILD this week, I’ll be looking to answer one question – what does it mean to be a Microsoft developer here in the 2010’s? What is the future of the Microsoft development platform? Sure, Visual Studio is still alive and well and Microsoft realizes that there’s a huge install base of .NET developers actively working on solutions. But they’ve ratcheted down the messaging around their development stack and instead focussed on promoting development for their platforms and services. Last year at BUILD with the release of Windows 8, Microsoft just breached the walls of its cocoon. After this BUILD and the organizational change announcements in July, we’ll see what Microsoft looks like fully emerged from its metamorphosis.

  • Stackify Aims to Put More ‘Dev’ in ‘DevOps’

    - by Matt Watson
    Originally published on VisualStudioMagazine.com on 8/22/2012 by Keith Ward.The Kansas City-based startup wants to make it easier for developers to examine the network stack and find problems in code.The first part of “DevOps” is “Dev”. But according to Matt Watson, Devs aren’t connected enough with Ops, and it’s time that changed.He founded the startup company Stackify earlier this year to do something about it. Stackify gives developers unprecedented access to the IT side of the equation, Watson says, without putting additional burden on the system and network administrators who ultimately ensure the health of the environment.“We need a product designed for developers, with the goal of getting them more involved in operations and app support. Now, there’s next to nothing designed for developers,” Watson says. Stackify allows developers to search the network stack to troubleshoot problems in their software that might otherwise take days of coordination between development and IT teams to solve.Stackify allows developers to search log files, configuration files, databases and other infrastructure to locate errors. A key to this is that the developers are normally granted read-only access, soothing admin fears that developers will upload bad code to their servers.Implementation starts with data collection on the servers. Among the information gleaned is application discovery, server monitoring, file access, and other data collection, according to Stackify’s Web site. Watson confirmed that Stackify works seamlessly with virtualized environments as well.Although the data collection software must be installed on Windows servers, it can monitor both Windows and Linux servers. Once collection’s finished, developers have the kind of information they need, without causing heartburn for the IT staff.Stackify is a 100 percent cloud-based service. The company uses Windows Azure for hosting, a decision Watson’s happy with. With Azure, he says, “It’s nice to have all the dev tools like cache and table storage.” Although there have been a few glitches here and there with the service, it’s run very smoothly for the most part, he adds.Stackify is currently in a closed beta, with a public release scheduled for October. Watson says that pricing is expected to be $25 per month, per server, with volume discounts available. He adds that the target audience is companies with at least five developers.Watson founded Stackify after selling his last company, VinSolutions, to AutoTrader.com for “close to $150 million”, according to press accounts. Watson has since  founded the Watson Technology Group, which focuses on angel investing.About the Author: Keith Ward is the editor in chief of Visual Studio Magazine.

  • Best of "The Moth" 2010

    - by Daniel Moth
    It is the time again (like in 2004, 2005, 2006, 2007, 2008, 2009) to look back at my blog for the past year and identify areas of interest that seem to be more prominent than others. After doing so, representative posts follow in my top 5 list (in random order). 1. This was the year where I had to move for the first time since 2004 my blog engine (blogger.com –> dasBlog), host provider (zen –> godaddy), web server technology and OS (apache on Linux –> IIS on Windows Server). My goal was not to break any permalinks or the look and feel of this website. A series of posts covered how I achieved that goal, culminating in a tool for others to use if they wanted to do the same: Tool to convert blogger.com content to dasBlog. Going forward I aim to be sharing more small code utilities like that one… 2. At work I am known for being fairly responsive on email, and more importantly never dropping email balls on the floor. This is due to my email processing system, which I shared here: Processing Email in Outlook. I will be sharing more tips with regards to making the best of the Office products. 3. There is no doubt in my mind that this is the year people will remember as the one where Microsoft finally fights back in the mobile space. Even though the new platform means my Windows Mobile book sales will dwindle :-), I am ecstatic about Windows Phone 7 both as a consumer and as a developer. On the release day, to get you started I shared the top 10 Windows Phone 7 developer resources. I will be sharing my tips from my experience in writing code for and consuming this new platform… 4. For my HPC developer friends using Visual Studio, I shared Slides and code for MPI Cluster Debugger and also gave you all the links you need for getting started with Dryad and DryadLINQ from MSR. Expect more from me on cluster development in the coming year… 5. Still in the HPC space, but actually also in the game and even mainstream development, the big disruption and opportunity comes in the form of GPGPU and, on the Microsoft platform, (currently) DirectCompute. Expect more from me on gpgpu development in the coming year… Subscribe via the link on the left to stay tuned for 2011… I wish you a very Happy New Year (with whatever definition of happiness works for you)! Comments about this post welcome at the original blog.

  • A few things I learned regarding Azure billing policies

    - by Vincent Grondin
    An hour of small computing time: 0,12$ per hour A Gig of storage in the cloud: 0,15$ per hour 1 Gig of relational database using Azure SQL: 9,99$  per month A Visual Studio Professional with MSDN Premium account: 2500$ per year Winning an MSDN Professional account that comes preloaded with 750 free hours of Azure per month:  PRICELESS !!!      But was it really free???? Hmmm… Let’s see.....   Here's a few things I learned regarding Azure billing policies when I attended a promotional training at Microsoft last week...   1)  An instance deployed in the cloud really means whatever you upload in there... it doesn't matter if it's in STAGING OR PRODUCTION!!!!   Your MSDN account comes with 750 free hours of small computing time per month which should be enough hours per month for one instance of one application deployed in the cloud...  So we're cool, the application you run in the cloud doesn't cost you a penny....  BUT the one that's in staging is still consuming time!!!   So if you don’t want to end up having to pay 42$ at the end of the month on your credit card like this happened to a friend of mine, DELETE them staging applications once you’ve put them in production! This also applies to the instance count you can modify in the configuration file… So stop and think before you decide you want to spawn 50 of those hello world apps  .     2) If you have an MSDN account, then you have the promotional 750 hours of Azure credits per month and can use the Azure credits to explore the Cloud! But be aware, this promotion ends in 8 months (maybe more like 7 now) and then you will most likely go back to the standard 250 hours of Azure credits. If you do not delete your applications by then, you’ll get billed for the extra hours, believe me…   There is a switch that you can toggle and which will STOP your automatic enrollment after the promotion and prevent you from renewing the Azure Account automatically. Yes the default setting is to automatically renew your account and remember, you entered your credit card information in the registration process so, yes, you WILL be billed…  Go disable that ASAP    Log into your account, go to “Windows Azure Platform” then click the “Subscriptions” tab and on the right side, you’ll see a drop down with different “Actions” into it… Choose “Opt out of auto renew” and, NOW you’re safe…   Still, this is a great offer by Microsoft and I think everyone that has a chance should play a bit with Azure to get to know this technology a bit more...     Happy Cloud Computing All

  • Ask the Readers: Do You Prefer Computers, Game Consoles, or Other Devices for Your Gaming Needs?

    - by Asian Angel
    Nearly everyone who has access to a computer will play games on it at some point, but many people also use a separate game platform as well. What we would like to know this week is if you prefer using a computer, game consoles, or other devices for your gaming needs. Photo of Faith and Kate Connors from Mirror’s Edge by Tamahikari Tammas. Video games are a perfect way to relax and have fun at home (or at work if you can sneak in some game time!). The increasing variety of devices available with each passing year are making it easier to have access to a gaming platform to suit your needs or “darkest gaming desires”. For many people their computers are the perfect platform…they can play Flash-based games in their browsers, use the default set of games that come with their system, and install any extras that catch their eyes. The added benefit is that when game time is over they can drop right into their browsing, e-mail, personal projects, or work without having to switch hardware. The convenience of the “all-in-one” platform is certainly appealing! Perhaps you prefer to use your computer for other activities outside of gaming and own one or more separate game consoles. You might have chosen an Xbox, Playstation, or Nintendo for example. Maybe a hand-held is preferable for its’ size and portability. Then there are mobile phones and the iPad… With so many options it may feel hard to choose the right platform(s) without a good bit of research regarding display, availability of games for a particular platform, how long before the platform starts to become “obsolete”, etc. What we would like to know this week is which gaming platform you prefer. Is there only one that you choose to use or do you use multiple platforms for gaming? Is there a particular reason such as convenience for your choices? You may even be keeping an older platform around just for a certain game (or games) made for it. Are there any recommendations or advice that you would like to share with your fellow readers?

  • The importance of Unit Testing in BI

    - by Davide Mauri
    One of the main steps in the process we internally use to develop a BI solution is the implementation of Unit Test of you BI Data. As you may already know, I’ve create a simple (for now) tool that leverages NUnit to allow us to quickly create Unit Testing without having to resort to use Visual Studio Database Professional: http://queryunit.codeplex.com/ Once you have a tool like this one, you can start also to make sure that your BI solution (DWH and CUBE) is not only structurally sound (I mean, the cube or the report gets processed correctly), but you can also check that the logical integrity of your business rules is enforced. For example let’s say that the customer tell you that they will never create an invoice for a specific product-line in 2010 since that product-line is dismissed and will never be sold again. Ok we know that this in theory is true, but a lot of this business rule effectiveness depends on the fact the people does not do a mistake while inserting new orders/invoices and the ERP used implements a check for this business logic. Unfortunately these last two hypotesis are not always true, so you may find yourself really having some invoices for a product line that doesn’t exists anymore. Maybe this kind of situation in future will be solved using Master Data Management but, meanwhile, how you can give and idea of the data quality to your customers? How can you check that logical integrity of the analytical data you produce is exactly what you expect? Well, Unit Testing of a DWH or a CUBE can be a solution. Once you have defined your test suite, by writing SQL and MDX queries that checks that your data is what you expect to be, if you use NUnit (and QueryUnit does), you can then use a tool like NUnit2Report to create a nice HTML report that can be shipped via email to give information of data quality: In addition to that, since NUnit produces an XML file as a result, you can also import it into a SQL Server Database and then monitor the quality of data over time. I’ll be speaking about this approach (and more in general about how to “engineer” a BI solution) at the next European SQL PASS Adaptive BI Best Practices http://www.sqlpass.org/summit/eu2010/Agenda/ProgramSessions/AdaptiveBIBestPratices.aspx I’ll enjoy discussing with you all about this, so see you there! And remember: “if ain't tested it's broken!” (Sorry I don’t remember how said that in first place :-)) Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • SQL SERVER – ColumnStore Index – Batch Mode vs Row Mode

    - by pinaldave
    What do you do when you are in a hurry and hear someone say things which you do not agree or is wrong? Well, let me tell you what I do or what I recently did. I was walking by and heard someone mentioning “Columnstore Index are really great as they are using Batch Mode which makes them seriously fast.” While I was passing by and I heard this statement my first reaction was I thought Columnstore Index can use both – Batch Mode and Row Mode. I stopped by even though I was in a hurry and asked the person if he meant that Columnstore indexes are seriously fast because they use Batch Mode all the time or Batch Mode is one of the reasons for Columnstore Index to be faster. He responded that Columnstore Indexes can run only in Batch Mode. However, I do not like to confront anybody without hearing their complete story. Honestly, I like to do information sharing and avoid confronting as much as possible. There are always ways to communicate the same positively. Well, this is what I did, I quickly pull up my earlier article on Columnstore Index and copied the script to SQL Server Management Studio. I created two versions of the script. 1) Very Large Table 2) Reasonably Small Table. I a query which uses columnstore index on both of the versions. I found very interesting result of the my tests. I saved my tests and sent it to the person who mentioned about that Columnstore Indexes are using Batch Mode only. He immediately acknowledged that indeed he was incorrect in saying that Columnstore Index uses only Batch Mode. What really caught my attention is that he also thanked me for sending him detail email instead of just having argument where he and I both were standing in the corridor and neither have no way to prove any theory. Here is the screenshots of the both the scenarios. 1) Columnstore Index using Batch Mode 2) Columnstore Index using Row Mode Here is the logic behind when Columnstore Index uses Batch Mode and when it uses Row Mode. A batch typically represents about 1000 rows of data. Batch mode processing also uses algorithms that are optimized for the multicore CPUs and increased memory throughput.  Batch mode processing spreads metadata access costs and overhead over all the rows in a batch.  Batch mode processing operates on compressed data when possible leading superior performance. Here is one last point – Columnstore Index can use Batch Mode or Row Mode but Batch Mode processing is only available in Columnstore Index. I hope this statement truly sums up the whole concept.

  • Backup Meta-Data

    - by BuckWoody
    I'm working on a PowerShell script to show me the trending durations of my backup activities. The first thing I need is the data, so I looked at the Standard Reports in SQL Server Management Studio, and found a report that suited my needs, so I pulled out the script that it runs and modified it to this T-SQL Script. A few words here - you need to be in the MSDB database for this to run, and you can add a WHERE clause to limit to a database, timeframe, type of backup, whatever. For that matter, I won't use all of the data in this query in my PowerShell script, but it gives me lots of avenues to graph: SELECT distinct t1.name AS 'DatabaseName' ,(datediff( ss,  t3.backup_start_date, t3.backup_finish_date)) AS 'DurationInSeconds' ,t3.user_name AS 'UserResponsible' ,t3.name AS backup_name ,t3.description ,t3.backup_start_date ,t3.backup_finish_date ,CASE WHEN t3.type = 'D' THEN 'Database' WHEN t3.type = 'L' THEN 'Log' WHEN t3.type = 'F' THEN 'FileOrFilegroup' WHEN t3.type = 'G' THEN 'DifferentialFile' WHEN t3.type = 'P' THEN 'Partial' WHEN t3.type = 'Q' THEN 'DifferentialPartial' END AS 'BackupType' ,t3.backup_size AS 'BackupSizeKB' ,t6.physical_device_name ,CASE WHEN t6.device_type = 2 THEN 'Disk' WHEN t6.device_type = 102 THEN 'Disk' WHEN t6.device_type = 5 THEN 'Tape' WHEN t6.device_type = 105 THEN 'Tape' END AS 'DeviceType' ,t3.recovery_model  FROM sys.databases t1 INNER JOIN backupset t3 ON (t3.database_name = t1.name )  LEFT OUTER JOIN backupmediaset t5 ON ( t3.media_set_id = t5.media_set_id ) LEFT OUTER JOIN backupmediafamily t6 ON ( t6.media_set_id = t5.media_set_id ) ORDER BY backup_start_date DESC I'll munge this into my Excel PowerShell chart script tomorrow. Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. Yes, there are always multiple ways to do things, and this script may not work in every situation, for everything. It’s just a script, people. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary. Void where prohibited. Offer good for a limited time only. Keep out of reach of small children. Do not operate heavy machinery while using this script. If you experience blurry vision, indigestion or diarrhea during the operation of this script, see a physician immediately.
