• New version of SQL Server Data Tools is now available

  - by jamiet

  If you don’t follow the SQL Server Data Tools (SSDT) blog then you may not know that two days ago an updated version of SSDT was released (and by SSDT I mean the database projects, not the SSIS/SSRS/SSAS stuff) along with a new version of the SSDT Power Tools. This release incorporates a an updated version of the SQL Server Data Tier Application Framework (aka DAC Framework, aka DacFX) which you can read about on Adam Mahood’s blog post SQL Server Data-Tier Application Framework (September 2012) Available. DacFX is essentially all the gubbins that you need to extract and publish .dacpacs and according to Adam’s post it incorporates a new feature that I think is very interesting indeed: Extract DACPAC with data – Creates a database snapshot file (.dacpac) from a live SQL Server or Windows Azure SQL Database that contains data from user tables in addition to the database schema. These packages can be published to a new or existing SQL Server or Windows Azure SQL Database using the SqlPackage.exe Publish action. Data contained in package replaces the existing data in the target database. In short, .dacpacs can now include data as well as schema. I’m very excited about this because one of my long-standing complaints about SSDT (and its many forebears) is that whilst it has great support for declarative development of schema it does not provide anything similar for data – if you want to deploy data from your SSDT projects then you have to write Post-Deployment MERGE scripts. This new feature for .dacpacs does not change that situation yet however it is a very important pre-requisite so I am hoping that a feature to provide declaration of data (in addition to declaration of schema which we have today) is going to light up in SSDT in the not too distant future.

• Examining ASP.NET's Membership, Roles, and Profile - Part 18

  Membership, in a nutshell, is a framework build into the .NET Framework that supports creating, authenticating, deleting, and modifying user account information. Each user account has a set of core properties: username, password, email, a security question and answer, whether or not the account has been approved, whether or not the user is locked out of the system, and so on. These user-specific properties are certainly helpful, but they're hardly exhaustive - it's not uncommon for an application to need to track additional user-specific properties. For example, an online messageboard site might want to also also associate a signature, homepage URL, and IM address with each user account. There are two ways to associate additional information with user accounts when using the Membership model. The first - which affords the greatest flexibility, but requires the most upfront effort - is to create a custom data store for this information. If you are using the SqlMembershipProvider, this would mean creating an additional database table that had as a primary key the UserId value from the aspnet_Users table and columns for each of the additional user properties. The second option is to use the Profile system, which allows additional user-specific properties to be defined in a configuration file. (See Part 6 for an in-depth look at the Profile system.) This article explores how to store additional user information in a separate database table. We'll see how to allow a signed in user to update these additional user-specific properties and how to create a page to display information about a selected user. What's more, we'll look at using ASP.NET Routing to display user information using an SEO-friendly, human-readable URL like www.yoursite.com/Users/username. Read on to learn more! Read More >

• HTML5 Form Validation

  - by Stephen.Walther

  The latest versions of Google Chrome (16+), Mozilla Firefox (8+), and Internet Explorer (10+) all support HTML5 client-side validation. It is time to take HTML5 validation seriously. The purpose of the blog post is to describe how you can take advantage of HTML5 client-side validation regardless of the type of application that you are building. You learn how to use the HTML5 validation attributes, how to perform custom validation using the JavaScript validation constraint API, and how to simulate HTML5 validation on older browsers by taking advantage of a jQuery plugin. Finally, we discuss the security issues related to using client-side validation. Using Client-Side Validation Attributes The HTML5 specification discusses several attributes which you can use with INPUT elements to perform client-side validation including the required, pattern, min, max, step, and maxlength attributes. For example, you use the required attribute to require a user to enter a value for an INPUT element. The following form demonstrates how you can make the firstName and lastName form fields required: <!DOCTYPE html> <html > <head> <title>Required Demo</title> </head> <body> <form> <label> First Name: <input required title="First Name is Required!" /> </label> <label> Last Name: <input required title="Last Name is Required!" /> </label> <button>Register</button> </form> </body> </html> If you attempt to submit this form without entering a value for firstName or lastName then you get the validation error message: Notice that the value of the title attribute is used to display the validation error message “First Name is Required!”. The title attribute does not work this way with the current version of Firefox. If you want to display a custom validation error message with Firefox then you need to include an x-moz-errormessage attribute like this: <input required title="First Name is Required!" x-moz-errormessage="First Name is Required!" /> The pattern attribute enables you to validate the value of an INPUT element against a regular expression. For example, the following form includes a social security number field which includes a pattern attribute: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Pattern</title> </head> <body> <form> <label> Social Security Number: <input required pattern="^\d{3}-\d{2}-\d{4}$" title="###-##-####" /> </label> <button>Register</button> </form> </body> </html> The regular expression in the form above requires the social security number to match the pattern ###-##-####: Notice that the input field includes both a pattern and a required validation attribute. If you don’t enter a value then the regular expression is never triggered. You need to include the required attribute to force a user to enter a value and cause the value to be validated against the regular expression. Custom Validation You can take advantage of the HTML5 constraint validation API to perform custom validation. You can perform any custom validation that you need. The only requirement is that you write a JavaScript function. For example, when booking a hotel room, you might want to validate that the Arrival Date is in the future instead of the past: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Constraint Validation API</title> </head> <body> <form> <label> Arrival Date: <input id="arrivalDate" type="date" required /> </label> <button>Submit Reservation</button> </form> <script type="text/javascript"> var arrivalDate = document.getElementById("arrivalDate"); arrivalDate.addEventListener("input", function() { var value = new Date(arrivalDate.value); if (value < new Date()) { arrivalDate.setCustomValidity("Arrival date must be after now!"); } else { arrivalDate.setCustomValidity(""); } }); </script> </body> </html> The form above contains an input field named arrivalDate. Entering a value into the arrivalDate field triggers the input event. The JavaScript code adds an event listener for the input event and checks whether the date entered is greater than the current date. If validation fails then the validation error message “Arrival date must be after now!” is assigned to the arrivalDate input field by calling the setCustomValidity() method of the validation constraint API. Otherwise, the validation error message is cleared by calling setCustomValidity() with an empty string. HTML5 Validation and Older Browsers But what about older browsers? For example, what about Apple Safari and versions of Microsoft Internet Explorer older than Internet Explorer 10? What the world really needs is a jQuery plugin which provides backwards compatibility for the HTML5 validation attributes. If a browser supports the HTML5 validation attributes then the plugin would do nothing. Otherwise, the plugin would add support for the attributes. Unfortunately, as far as I know, this plugin does not exist. I have not been able to find any plugin which supports both the required and pattern attributes for older browsers, but does not get in the way of these attributes in the case of newer browsers. There are several jQuery plugins which provide partial support for the HTML5 validation attributes including: · jQuery Validation — http://docs.jquery.com/Plugins/Validation · html5Form — http://www.matiasmancini.com.ar/jquery-plugin-ajax-form-validation-html5.html · h5Validate — http://ericleads.com/h5validate/ The jQuery Validation plugin – the most popular JavaScript validation library – supports the HTML5 required attribute, but it does not support the HTML5 pattern attribute. Likewise, the html5Form plugin does not support the pattern attribute. The h5Validate plugin provides the best support for the HTML5 validation attributes. The following page illustrates how this plugin supports both the required and pattern attributes: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>h5Validate</title> <style type="text/css"> .validationError { border: solid 2px red; } .validationValid { border: solid 2px green; } </style> </head> <body> <form id="customerForm"> <label> First Name: <input id="firstName" required /> </label> <label> Social Security Number: <input id="ssn" required pattern="^\d{3}-\d{2}-\d{4}$" title="Expected pattern is ###-##-####" /> </label> <input type="submit" /> </form> <script type="text/javascript" src="Scripts/jquery-1.4.4.min.js"></script> <script type="text/javascript" src="Scripts/jquery.h5validate.js"></script> <script type="text/javascript"> // Enable h5Validate plugin $("#customerForm").h5Validate({ errorClass: "validationError", validClass: "validationValid" }); // Prevent form submission when errors $("#customerForm").submit(function (evt) { if ($("#customerForm").h5Validate("allValid") === false) { evt.preventDefault(); } }); </script> </body> </html> When an input field fails validation, the validationError CSS class is applied to the field and the field appears with a red border. When an input field passes validation, the validationValid CSS class is applied to the field and the field appears with a green border. From the perspective of HTML5 validation, the h5Validate plugin is the best of the plugins. It adds support for the required and pattern attributes to browsers which do not natively support these attributes such as IE9. However, this plugin does not include everything in my wish list for a perfect HTML5 validation plugin. Here’s my wish list for the perfect back compat HTML5 validation plugin: 1. The plugin would disable itself when used with a browser which natively supports HTML5 validation attributes. The plugin should not be too greedy – it should not handle validation when a browser could do the work itself. 2. The plugin should simulate the same user interface for displaying validation error messages as the user interface displayed by browsers which natively support HTML5 validation. Chrome, Firefox, and Internet Explorer all display validation errors in a popup. The perfect plugin would also display a popup. 3. Finally, the plugin would add support for the setCustomValidity() method and the other methods of the HTML5 validation constraint API. That way, you could implement custom validation in a standards compatible way and you would know that it worked across all browsers both old and new. Security It would be irresponsible of me to end this blog post without mentioning the issue of security. It is important to remember that any client-side validation — including HTML5 validation — can be bypassed. You should use client-side validation with the intention to create a better user experience. Client validation is great for providing a user with immediate feedback when the user is in the process of completing a form. However, client-side validation cannot prevent an evil hacker from submitting unexpected form data to your web server. You should always enforce your validation rules on the server. The only way to ensure that a required field has a value is to verify that the required field has a value on the server. The HTML5 required attribute does not guarantee anything. Summary The goal of this blog post was to describe the support for validation contained in the HTML5 standard. You learned how to use both the required and the pattern attributes in an HTML5 form. We also discussed how you can implement custom validation by taking advantage of the setCustomValidity() method. Finally, I discussed the available jQuery plugins for adding support for the HTM5 validation attributes to older browsers. Unfortunately, I am unaware of any jQuery plugin which provides a perfect solution to the problem of backwards compatibility.

• How Can I Install LibreOffice Base?

  Useful info: I have tried running sudo dpkg --configure -a and sudo apt-get install -f with no result. I am running Kubuntu 11.10 (the updater is far too unreliable to ever be trusted with performing a version upgrade) The rest of LibreOffice seems to work fine (apart from an annoying bug where tooltips are shown as black text on black background...)

• scheme vs common lisp: war stories

  - by SuperElectric

  There are no shortage of vague "Scheme vs Common Lisp" questions on StackOverflow, so I want to make this one more focused. The question is for people who have coded in both languages: While coding in Scheme, what specific elements of your Common Lisp coding experience did you miss most? Or, inversely, while coding in Common Lisp, what did you miss from coding in Scheme? I don't necessarily mean just language features. The following are all valid things to miss, as far as the question is concerned: Specific libraries. Specific features of development environments like SLIME, DrRacket, etc. Features of particular implementations, like Gambit's ability to write blocks of C code directly into your Scheme source. And of course, language features. Examples of the sort of answers I'm hoping for: "I was trying to implement X in Common Lisp, and if I had Scheme's first-class continuations, I totally would've just done Y, but instead I had to do Z, which was more of a pain." "Scripting the build process in Scheme project, got increasingly painful as my source tree grew and I linked in more and more C libraries. For my next project, I moved back to Common Lisp." "I have a large existing C++ codebase, and for me, being able to embed C++ calls directly in my Gambit Scheme code was totally worth any shortcomings that Scheme may have vs Common Lisp, even including lack of SWIG support." So, I'm hoping for war stories, rather than general sentiments like "Scheme is a simpler language" etc.

• Book Review: Getting Started With Window 8 Apps By Ben Dewey

  - by Tim Murphy

  When O’Reilly gave me an opportunity to review this book I was excited.  It gave me a reason to finally put some time into this new platform and what developers will need to learn in order to be successful. This book by Ben Dewey is only 92 pages long, so if you were looking for an in-depth treatment of Windows 8 development you will need supplemental materials.  It is also due for an update from the perspective of recent changes made by Microsoft prior to the final release of the OS and tools.  This causes a few issues if you try to run the code samples because of namespace changes. I was encouraged by the fact that the author didn’t do the typical “hello world” app.  He uses a lot of pattern based development techniques and hits many of the main topics including: Application lifecycle Charms integration Tiles Sensors The lifecycle is critical for anyone who hasn’t done mobile development before.  Limited resources on these devices mean that the OS can suspend or kill your app altogether if it decides it needs to.  He covers tombstoning which is the key to Windows 8 and Windows Phone lifecycle management. He also dedicates a chapter to marketing and distributing the application you build.  From my experience with Windows Phone development this is crucial information.  You need to know how to test your application so that it is going to pass certification and present your app so that it is going to get noticed amongst thousands of other apps. The main things that I wish had been in the book explanations of more of the common controls and more complete explanation of patterns that were implemented. In the end this book is a good foundation getting exposure to the concepts that underlie this new version of the Windows platform and how it effects developers.  It isn’t a book that I would suggest for someone just getting into development with no understanding of pattern based development. del.icio.us Tags: Windows 8,O'Reilly,Ben Dewey,Book Review,Review

• Methodology behind fetching large XML data sets in pieces

  - by Jerry Dodge

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

• C#/.NET Little Wonders: The EventHandler and EventHandler&lt;TEventArgs&gt; delegates

  - by James Michael Hare

  Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. In the last two weeks, we examined the Action family of delegates (and delegates in general), and the Func family of delegates and how they can be used to support generic, reusable algorithms and classes. So this week, we are going to look at a handy pair of delegates that can be used to eliminate the need for defining custom delegates when creating events: the EventHandler and EventHandler<TEventArgs> delegates. Events and delegates Before we begin, let’s quickly consider events in .NET.  According to the MSDN: An event in C# is a way for a class to provide notifications to clients of that class when some interesting thing happens to an object. So, basically, you can create an event in a type so that users of that type can subscribe to notifications of things of interest.  How is this different than some of the delegate programming that we talked about in the last two weeks?  Well, you can think of an event as a special access modifier on a delegate.  Some differences between the two are: Events are a special access case of delegates They behave much like delegates instances inside the type they are declared in, but outside of that type they can only be (un)subscribed to. Events can specify add/remove behavior explicitly If you want to do additional work when someone subscribes or unsubscribes to an event, you can specify the add and remove actions explicitly. Events have access modifiers, but these only specify the access level of those who can (un)subscribe A public event, for example, means anyone can (un)subscribe, but it does not mean that anyone can raise (invoke) the event directly.  Events can only be raised by the type that contains them In contrast, if a delegate is visible, it can be invoked outside of the object (not even in a sub-class!). Events tend to be for notifications only, and should be treated as optional Semantically speaking, events typically don’t perform work on the the class directly, but tend to just notify subscribers when something of note occurs. My basic rule-of-thumb is that if you are just wanting to notify any listeners (who may or may not care) that something has happened, use an event.  However, if you want the caller to provide some function to perform to direct the class about how it should perform work, make it a delegate. Declaring events using custom delegates To declare an event in a type, we simply use the event keyword and specify its delegate type.  For example, let’s say you wanted to create a new TimeOfDayTimer that triggers at a given time of the day (as opposed to on an interval).  We could write something like this: 1: public delegate void TimeOfDayHandler(object source, ElapsedEventArgs e); 2:  3: // A timer that will fire at time of day each day. 4: public class TimeOfDayTimer : IDisposable 5: { 6: // Event that is triggered at time of day. 7: public event TimeOfDayHandler Elapsed; 8:  9: // ... 10: } The first thing to note is that the event is a delegate type, which tells us what types of methods may subscribe to it.  The second thing to note is the signature of the event handler delegate, according to the MSDN: The standard signature of an event handler delegate defines a method that does not return a value, whose first parameter is of type Object and refers to the instance that raises the event, and whose second parameter is derived from type EventArgs and holds the event data. If the event does not generate event data, the second parameter is simply an instance of EventArgs. Otherwise, the second parameter is a custom type derived from EventArgs and supplies any fields or properties needed to hold the event data. So, in a nutshell, the event handler delegates should return void and take two parameters: An object reference to the object that raised the event. An EventArgs (or a subclass of EventArgs) reference to event specific information. Even if your event has no additional information to provide, you are still expected to provide an EventArgs instance.  In this case, feel free to pass the EventArgs.Empty singleton instead of creating new instances of EventArgs (to avoid generating unneeded memory garbage). The EventHandler delegate Because many events have no additional information to pass, and thus do not require custom EventArgs, the signature of the delegates for subscribing to these events is typically: 1: // always takes an object and an EventArgs reference 2: public delegate void EventHandler(object sender, EventArgs e) It would be insane to recreate this delegate for every class that had a basic event with no additional event data, so there already exists a delegate for you called EventHandler that has this very definition!  Feel free to use it to define any events which supply no additional event information: 1: public class Cache 2: { 3: // event that is raised whenever the cache performs a cleanup 4: public event EventHandler OnCleanup; 5:  6: // ... 7: } This will handle any event with the standard EventArgs (no additional information).  But what of events that do need to supply additional information?  Does that mean we’re out of luck for subclasses of EventArgs?  That’s where the generic for of EventHandler comes into play… The generic EventHandler<TEventArgs> delegate Starting with the introduction of generics in .NET 2.0, we have a generic delegate called EventHandler<TEventArgs>.  Its signature is as follows: 1: public delegate void EventHandler<TEventArgs>(object sender, TEventArgs e) 2: where TEventArgs : EventArgs This is similar to EventHandler except it has been made generic to support the more general case.  Thus, it will work for any delegate where the first argument is an object (the sender) and the second argument is a class derived from EventArgs (the event data). For example, let’s say we wanted to create a message receiver, and we wanted it to have a few events such as OnConnected that will tell us when a connection is established (probably with no additional information) and OnMessageReceived that will tell us when a new message arrives (probably with a string for the new message text). So for OnMessageReceived, our MessageReceivedEventArgs might look like this: 1: public sealed class MessageReceivedEventArgs : EventArgs 2: { 3: public string Message { get; set; } 4: } And since OnConnected needs no event argument type defined, our class might look something like this: 1: public class MessageReceiver 2: { 3: // event that is called when the receiver connects with sender 4: public event EventHandler OnConnected; 5:  6: // event that is called when a new message is received. 7: public event EventHandler<MessageReceivedEventArgs> OnMessageReceived; 8:  9: // ... 10: } Notice, nowhere did we have to define a delegate to fit our event definition, the EventHandler and generic EventHandler<TEventArgs> delegates fit almost anything we’d need to do with events. Sidebar: Thread-safety and raising an event When the time comes to raise an event, we should always check to make sure there are subscribers, and then only raise the event if anyone is subscribed.  This is important because if no one is subscribed to the event, then the instance will be null and we will get a NullReferenceException if we attempt to raise the event. 1: // This protects against NullReferenceException... or does it? 2: if (OnMessageReceived != null) 3: { 4: OnMessageReceived(this, new MessageReceivedEventArgs(aMessage)); 5: } The above code seems to handle the null reference if no one is subscribed, but there’s a problem if this is being used in multi-threaded environments.  For example, assume we have thread A which is about to raise the event, and it checks and clears the null check and is about to raise the event.  However, before it can do that thread B unsubscribes to the event, which sets the delegate to null.  Now, when thread A attempts to raise the event, this causes the NullReferenceException that we were hoping to avoid! To counter this, the simplest best-practice method is to copy the event (just a multicast delegate) to a temporary local variable just before we raise it.  Since we are inside the class where this event is being raised, we can copy it to a local variable like this, and it will protect us from multi-threading since multicast delegates are immutable and assignments are atomic: 1: // always make copy of the event multi-cast delegate before checking 2: // for null to avoid race-condition between the null-check and raising it. 3: var handler = OnMessageReceived; 4: 5: if (handler != null) 6: { 7: handler(this, new MessageReceivedEventArgs(aMessage)); 8: } The very slight trade-off is that it’s possible a class may get an event after it unsubscribes in a multi-threaded environment, but this is a small risk and classes should be prepared for this possibility anyway.  For a more detailed discussion on this, check out this excellent Eric Lippert blog post on Events and Races. Summary Generic delegates give us a lot of power to make generic algorithms and classes, and the EventHandler delegate family gives us the flexibility to create events easily, without needing to redefine delegates over and over.  Use them whenever you need to define events with or without specialized EventArgs.   Tweet Technorati Tags: .NET, C#, CSharp, Little Wonders, Generics, Delegates, EventHandler

• Help with a simple incremental backup script

  - by Evan

  I'd like to run the following incomplete script weekly in as a cron job to backup my home directory to an external drive mounted as /mnt/backups #!/bin/bash # TIMEDATE=$(date +%b-%d-%Y-%k:%M) LASTBACKUP=pathToDirWithLastBackup rsync -avr --numeric-ids --link-dest=$LASTBACKUP /home/myfiles /mnt/backups/myfiles$TIMEDATE My first question is how do I correctly set LASTBACKUP to the the the directory in /backs most recently created? Secondly, I'm under the impression that using --link-desk will mean that files in previous backups will not will not copied in later backups if they still exist but will rather symbolically link back to the originally copied files? However, I don't want to retain old files forever. What would be the best way to remove all the backups before a certain date without losing files that may think linked in those backups by currents backups? Basically I'm looking to merge all the files before a certain date to a certain date if that makes more sense than the way I initially framed the question :). Can --link-dest create hard links, and if so, just deleting previous directories wouldn't actually remove linked file? Finally I'd like to add a line to my script that compresses each newly created backup folder (/mnt/backups/myfiles$TIMEDATE). Based on reading this question, I was wondering if I could just use this line gzip --rsyncable /backups/myfiles$TIMEDATE after I run rsync so that sequential rsync --link-dest executions would find already copied and compressed files? I know that's a lot, so many thanks in advance for your help!!

• No USB 04b4:0307 mike input after 10.04

  - by Papou

  I am using an USB phone that is in fact a so-called "sound card" based on the 04b4:0307 chip. In fact, I have two different phones using 04b4:0307 and in fact I have a sound USB key too. This, I believe, is the start of why they call 04b4:0307 "ubiquitous" (instead of oh four bee...). But not "eternal". The mike worked in Ubuntu 9.10 and 10.04 but not later ([email protected]). "not working" means that 04b4:0307 shows in Sound Preference but that its vu-meter is mute. I have posted the full lsusb and the result of tests in various systems here: http://www.papou.byethost9.com/tmp/1043601.html Note: Tests done on VirtualBox (thankfully). But UbuntUnity no longer works on VB, so I used the LinuxMint equivalent. ?hat's fate. I could not find any problem report close enough. What should be my next step? I believe the problem occurs in module snd-usb-audio. One thing I might try if I knew how is hacking a DEB with its 10.04's source. I can hack DEBs. Any hint welcome on how to make a DEB overriding a kernel packed module. I mean that the newly installed module should have precedence, be loaded instead, the module installed with the kernel. TIA !

• Slide-decks from recent Adelaide SQL Server UG meetings

  - by Rob Farley

  The UK has been well represented this summer at the Adelaide SQL Server User Group, with presentations from Chris Testa-O’Neill (isn’t that the right link? Maybe try this one) and Martin Cairney. The slides are available here and here. I thought I’d particularly mention Martin’s, and how it’s relevant to this month’s T-SQL Tuesday. Martin spoke about Policy-Based Management and the Enterprise Policy Management Framework – something which is remarkably under-used, and yet which can really impact your ability to look after environments. If you have policies set up, then you can easily test each of your SQL instances to see if they are still satisfying a set of policies as defined. Automation (the topic of this month’s T-SQL Tuesday) should mean that your life is made easier, thereby enabling to you to do more. It shouldn’t remove the human element, but should remove (most of) the human errors. People still need to manage the situation, and work out what needs to be done, etc. We haven’t reached a point where computers can replace people, but they are very good at replace the mundaneness and monotony of our jobs. They’ve made our lives more interesting (although many would rightly argue that they have also made our lives more complex) by letting us focus on the stuff that changes. Martin named his talk Put Your Feet Up, which nicely expresses the fact that managing systems shouldn’t be about running around checking things all the time. It must be about having systems in place which tell you when things aren’t going well. It’s never quite as simple as being able to actually put your feet up, but certainly no system should require constant attention. It’s definitely a policy we at LobsterPot adhere to, whether it’s an alert to let us know that an ETL package has run successfully, or a script that generates some code for a report. If things can be automated, it reduces the chance of error, reduces the repetitive nature of work, and in general, keeps both consultants and clients much happier.

• Different Means Better with the new Windows Phone Developer Experience

  - by Nikita Polyakov

  If you are interested in the building mobile applications or have been in the past you might want to check out this blog post: Charlie Kindel - Different Means Better with the new Windows Phone Developer Experience What does this mean? Let me take some out takes and highlight them for you. It won’t come as a surprise to many to learn that the Windows Phone 7 developer experience builds upon the following GIANTS (among others): .NET Silverlight XNA platform Microsoft’s developer tools Web 2.0 standards and To enable the fantastic user experiences you’ve seen in the Windows Phone 7 Series demos so far we’ve had to break from the past. To deliver what developers expect in the developer platform we’ve had to change how phone apps were written. One result of this is previous Windows mobile applications will not run on Windows Phone 7 Series. To be clear, we will continue to work with our partners to deliver new devices based on Windows Mobile 6.5 and will support those products for many years to come, so it’s not as though one line ends as soon as the other begins. Once again, more details at MIX10. Start watching the @WP7Dev twitter account for more info.

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

  Unfortunately, there was no monthly meetup during May. Which means that it was even more important and interesting to go forward with a great topic for this month. Earlier this year I already spoke to Nayar Joolfoo about doing a presentation on version control systems (VCS), and he gladly agreed since then. It was just about finding the right date for the action. Furthermore, it was also a great coincidence that Avinash Meetoo announced on social media networks that Knowledge 7 is about to have a new training on "Effective git" - which correlates to a book title Avinash is currently working on - all the best with your approach on this and reach out to our MSCC craftsmen for recessions. Once again a big Thank you to Orange Ebene Accelerator on providing the venue for us, and the MSCC members involved on securing the time slot for our event. Unfortunately, it's kind of tough to get an early confirmation for our meetups these days. I'll keep you posted on that one as there are some interesting and exciting options coming up soon. Okay, let's talk about the meeting and version control systems again. As usual, I'm going to put my first impression of the meetup: "Absolutely great topic, questions and discussions on version control systems, like git or VSO. I was also highly pleased by the number of first timers and female IT geeks. Hopefully, we will be able to keep this trend for future get-togethers." And I really have to emphasise the amount of fresh blood coming to our gathering. Also, during the initial phase it was surprising to see that exactly those first-timers, most of them students at various campuses here on the island, had absolutely no idea about version control systems. More about further down... Reactions of other attendees If I counted correctly, we had a total of 17 attendees this month, and I'd like to give you feedback from some of them: "Inspiring. Helped me understand more about GIT." -- Sean on event comments "Joined the meetup today with literally no idea what is a version control system. I have several reasons why I should be starting to use VCS as from NOW in my projects. Thanks Nayar, Jochen and other participants :)" -- Yudish on event comments "Was present today and I'm very satisfied.I was not aware if there was a such tool like git available. Thanks to those who contributed for this meetup.It was great. Learned a lot from this meetup!!" -- Leonardo on event comments "Seriously, I can see how it’s going to ease my task and help me save time. Gone are the issues with files backups.  And since I’ll be doing my dissertation this year, using Git would help me a lot for my backups and I’m grateful to Nayar for the great explanation." -- Swan-Iyah on MSCC meetup : Version Controls Hopefully, I'll be able to get some other sources - personal blogs preferred - on our meeting. Geeks, thank you so much for those encouraging comments. It's really great to experience that we, all members of the MSCC, are doing the right thing to get more IT information out, and to help each other to improve and evolve in our professional careers. Our agenda of the day Honestly, we had a bumpy start... First, I was battling a little bit with the movable room divider in order to maximize the space. I mean, we had 24 RSVPs and usually there might additional people coming along. Then, for what ever reason, we were facing power outages - actually twice in short periods. Not too good for the projector after all, but hey it went smooth for the rest of the time being. And last but not least... our first speaker Nayar got stuck somewhere on the road. ;-) Anyway, not a real show-stopper and we used the time until Nayar's arrival to introduce ourselves a little bit. It is always important for me to get to know the "newbies" a little bit, and as a result we had lots of students of university - first year, second year and recent graduates - among them. Surprisingly, none of them was ever in contact with version control systems at all. I mean, this is a shocking discovery! Similar to the ability of touch-typing I'd say that being able to use (and master) any kind of version control system is compulsory in any job in the IT industry. Seriously, I'm wondering what is being taught during the classes on the campus. All of them have to work on semester assessments or final projects, even in small teams of 2-4 people. That's the perfect occasion to get started with VCS. Already in this phase, we had great input from more experienced VCS users, like Sean, Avinash and myself. git - a modern approach to VCS - Nayar What a tour! Nayar gave us the full round of git from start to finish, even touching some more advanced techniques. First, he started to explain about the importance of version control systems as an essential tool for software developers, even working alone on a project, and the ability to have a kind of "time machine" that allows you to inspect and revert to a previous version of source code at any time. Then he showed how easy it is to install git on an Ubuntu based system but also mentioned that git is literally available for any operating system, like Windows, Mac OS X and of course other Linux distributions. Next, he showed us how to set the initial configuration values of user name and email address which simplifies the daily usage of the git client while working with your repositories. Then he initialised and added a new repository for some local development of a blogging software. All commands were done using the command line interface (CLI) so that they can be repeated on any system as reference. The syntax and the procedure is always the same, and Nayar clearly mentioned this to the attendees. Now, having a git repository in place it was about time to work on some "important" changes on the blogging software - just for the sake of demonstrating the ease of use and power of git. One interesting question came very early: "How many commands do we have to learn? It looks quite difficult at the moment" - Well, rest assured that during daily development circles you will need less than 10 git commands on a regular base: git add, commit, push, pull, checkout, and merge And Nayar demo'd all of them. Much to the delight of everyone he also showed gitk which is the git repository browser. It's an UI tool to display changes in a repository or a selected set of commits. This includes visualizing the commit graph, showing information related to each commit, and the files in the trees of each revision. Using gitk to display and browse information of a local git repository And last but not least, we took advantage of the internet connectivity and reached out to various online portals offering git hosting for free. Nayar showed us how to push the local repository into a remote system on github. Showing the web-based git browser and history handling, and then also explained and demo'd on how to connect to existing online repositories in order to get access to either your own source code or other people's open source projects. Next to github, we also spoke about bitbucket and gitlab as potential online platforms for your projects. Have a look at the conditions and details about their free service packages and what you can get additionally as a paying customer. Usually, you already get a lot of services for up to five users for free but there might be other important aspects that might have an impact on your decision. Anyways, moving git-based repositories between systems is a piece of cake, and changing online platforms is possible at any stage of your development. Visual Studio Online (VSO) - Jochen Well, Nayar literally covered all elements of working with git during his session, including the use of external online platforms. So, what would be the advantage of talking about Visual Studio Online (VSO)? First of all, VSO is "just another" online platform for hosting and managing git repositories on remote systems, equivalent to github, bitbucket, or any other web site. At the moment (of writing), Microsoft also provides a free package of up to five users / developers on a git repository but there is more in that package. Of course, it is related to software development on the Windows systems and the bonds are tightened towards the use of Visual Studio but out of experience you are absolutely not restricted to that. Connecting a Linux or Mac OS X machine with a git client or an integrated development environment (IDE) like Eclipse or Xcode works as smooth as expected. So, why should one opt in for VSO? Well, one of the main aspects that I would like to mention here is that VSO integrates the Application Life Cycle Methodology (ALM) of Microsoft in their platform. Meaning that you get agile project management with Backlogs, Sprints, Burn-down charts as well as the ability to track tasks, bug reports and work items next to collaborative team chats. It's the whole package of agile development you'll get. And, something I mentioned briefly during the begin of our meeting, VSO gives you the possibility of an automated continuous integrated (CI) process which builds and can run tests of your source code after each commit of changes. Having a proper CI strategy is also part of the Clean Code Developer practices - on Level Green actually -, and not only simplifies your life as a software developer but also reduces the sources of potential errors. Seamless integration and automated deployment between Microsoft Azure Web Sites and git repository But my favourite feature is the seamless continuous deployment to Microsoft Azure. Especially, while working on web projects it's absolutely astounishing that as soon as you commit your chances it just takes a couple of seconds until your modifications are deployed and available on your Azure-hosted web sites. Upcoming Events and networking Due to the adjusted times, everybody was kind of hungry and we didn't follow up on networking or upcoming events - very unfortunate to my opinion and this will have an impact on future planning of our meetups. Because I rather would like to see more conversations during and at the end of our meetings than everyone just packing their laptops, bags and accessories and rush off to grab some food. I was hoping to get some information regarding this year's Code Challenge - supposedly to be organised during July? Maybe someone could leave a comment on that - but I couldn't get any updates. Well, I'll keep digging... In case that you would like to get more into git and how to use it effectively, please check out Knowledge 7's upcoming course on "Effective git". Thanks Avinash for your vital input into today's conversation and I'm looking forward to get a grip on your book title very soon. My resume of the day Do not work in IT without any kind of version control system! Seriously, without a VCS in place you're doing it wrong. It's like driving a car without seat belts attached or riding your bike without safety helmet. You don't do that! End of discussion. ;-) Nowadays, having access to free (as in cost) tools to install on your machine and numerous online platforms to host your source code for free for up to five users it's a no-brainer to get yourself familiar with VCS. Today's sessions gave a good overview on how to start using git and how to connect to various remote services like github or VSO.

• How to learn ASP.NET MVC without learning ASP.NET Web forms

  - by Naif

  First of all, I am not a web developer but I can say that I understand in general the difference between PHP, ASP.NET, etc. I have played a little with ASP.NET and C# as well, however, I didn't continue the learning path. Now I'd like to learn ASP.NET MVC but there is no a book for a beginner in ASP.NET MVC so I had a look at the tutorials but it seems that I need to learn C# first and SQL Server and HTML, am I right? So please tell me how can I learn ASP.NET MVC directly (I mean without learning ASP.NET Web forms). What do I need to learn (You can assume that I am an absolute beginner). Update: It is true that i can find ASP.NET MVC tutorial that explain ASP.NET MVC, but I used to find ASP.NET web forms books that explain SQL and C# at the same time and take you step by step. In ASP.NET MVC I don't know how can I start! How can I learn SQL in its own and C# in its own and then combine them with ASP.NET MVC!

• Stage3D Camera problem

  - by Thomas Versteeg

  I am trying to create a 2D Stage3D game where you can move the camera around the level in an RTS style. I thought about using Orthographic Matrix3D functions for this but when I try to scroll the whole "stage" also scrolls. This is the Camera code: public function Camera2D(width:int, height:int, zoom:Number = 1) { resize(width, height); _zoom = zoom; } public function resize(width:Number, height:Number):void { _width = width; _height = height; _projectionMatrix = makeMatrix(0, width, 0, height); _recalculate = true; } protected function makeMatrix(left:Number, right:Number, top:Number, bottom:Number, zNear:Number = 0, zFar:Number = 1):Matrix3D { return new Matrix3D(Vector.<Number>([ 2 / (right - left), 0, 0, 0, 0, 2 / (top - bottom), 0, 0, 0, 0, 1 / (zFar - zNear), 0, 0, 0, zNear / (zNear - zFar), 1 ])); } public function get viewMatrix():Matrix3D { if (_recalculate) { _recalculate = false; _viewMatrix.identity(); _viewMatrix.appendTranslation( -_width / 2 - _x, -_height / 2 - y, 0); _viewMatrix.appendScale(_zoom, _zoom, 1); _renderMatrix.identity(); _renderMatrix.append(_viewMatrix); _renderMatrix.append(_projectionMatrix); } return _renderMatrix; } Here are two screenshots to show what I mean: How do I only let the inside of the stage3D scroll and not the whole stage?

• Leaving Microsoft

  - by Stephen Walther

  After two and a half years working with the ASP.NET team, I’ve decided that this is the right time to leave Microsoft and, with the help of some friends, re-launch my ASP.NET training and consulting company. The company has the modest name Superexpert. While working on my Ph.D. at MIT, I was surrounded by professors and students who were passionate about knowledge. During the Internet boom, I was lucky enough to work side-by-side with some very smart and hard-working people to create several successful startups. However, the people I worked with at Microsoft were among the smartest and hardest working. Microsoft hires a small number of people and gives them huge responsibilities. It continues to amaze me that so few people work on the ASP.NET team when you consider how much the team produces. I had the opportunity to work with a number of inspiring people at Microsoft. I’ll miss working with Scott Hunter, Dave Reed, Boris Moore, Eilon Lipton, Scott Guthrie, James Senior, Jim Wang, Phil Haack, Damian Edwards, Vishal Joshi, Mike Pope, Jon Young, Dmitry Robsman, Simon Calvert, Stefan Schackow, and many others. I’m proud of what we accomplished while I was working at Microsoft. We reached out to the jQuery team and changed direction from Microsoft Ajax to jQuery. We successfully contributed several important new features to the open-source jQuery project including jQuery Templates, jQuery Data-Linking, jQuery Globalization, and (as John Resig announced at the last jQuery conference) jQuery Require. I’m looking forward to returning to training and consulting. We want to focus on providing consulting on the “right way” of building ASP.NET websites, which we call Modern ASP.NET applications. By Modern ASP.NET applications, I mean applications built with ASP.NET MVC, jQuery, HTML5, and Visual Studio ALM. Additionally, we want to help companies that have existing ASP.NET Web Forms applications migrate to ASP.NET MVC. If you are interested in having us provide training for your company or you need help building a custom ASP.NET application then please contact us at [email protected] or visit our website at Superexpert.com.

• Speaking at DevReach

  - by Sahil Malik

  Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Next week, I will be speaking at Devreach on the following topics - Authoring custom WCF services in SharePoint Sahil Malik, Level 400 We live in a different world today! Gone are the times when you built your webparts around postbacks! Welcome silverlight, jquery, bing maps, google maps, and many others! And there are many enhancements in SharePoint 2010 that let you build such applications, the question is which is right for you? In this session Sahil compares WCF REST Services in SharePoint, The client object model, and custom WCF services, and then dives deep into the WCF aspects of SharePoint. All code, very few slides!   Scalability and Performance of SharePoint 2010 Sahil Malik, Level 400 If there is a topic that has more misinformation than anything else, it has to be the scalability and performance aspects of SharePoint. Did you know, SharePoint 2010 has some real world, under the covers improvement that help it perform and scale better? This session involves taking a deep look under the covers into the specific improvements Microsoft has made between SharePoint 2007 and SharePoint 2010 that truly qualifies SharePoint 2010 as an enterprise scalable product. This doesn't mean the product doesn't have limits - but this session is a lot more than just limits written on a powerpoint slide. This presentation is a true under the scenes look at specific improvements!   Devreach is a premier conference, check out their very impressive speaker and sessions line up.

  Andy Mulholland: We need innovation! What does that mean? "The most common response would seem to be ‘I will know it when I see it’, which suggests business success is based on ‘getting lucky’. As you might expect business schools don’t agree with this and as A G Lafley, author of several works on the topic comments: 'Innovation is risky, but it’s not random. Innovators have a disciplined invention process.'" Capgemini CTO blogger Andy Mulholland.
