  • Changing Your Design for Testability

    Sometimes I come across a way of putting something that it is pithy good, not Hallmark trite, but an impactful and concise way of clarifying a previously obscure concept. A recent one of these happy occurrences was when I was reading the excellent Art of Unit Testing by Roy Osherove. After going through the basics of why youd want to test code and how to do it, Roy confronts a frequent objection to having unit tests, that it ends up changing how you design your components: When we write unit tests for our code, we are adding another end user (the test) to the object model. That end user is just as important as the original one, but it has different goals when using the model.  The test has specific requirements from the object model that seem to defy the basic logic behind a couple of object-oriented principles, mainly encapsulation. [emphasis added by me] When I read this, something clicked for me. I used to find it persuasive that because unit tests caused you to change your design they were more disruptive than they were worth. The counter argument I heard is that the disruption was OK, because testable design was just obviously better. That argument was not convincing as it seemed like delusional arrogance to suggest that any one of type of design was just inherently better for the particular applications I was building. What was missing was that I was not thinking of unit tests as an additional and equal end user to my design. If I accepted that proposition, than it was indeed obvious that a testable design was better because now all users of my component would be satisfied. Have I accepted that proposition? Id phrase it slightly different. I find more and more that having unit tests helps me write better, less buggy code before it gets to production or QA. As I write more unit tests, it gets easier to see how to create testable components, so I dont feel like its taking me as much extra time up front. I pick and choose components that seem most likely to benefit from automated tests and it is working out nicely. If you already implement Test Driven Development, this whole post was probably a waste of your time <g> If you hate the idea of unit tests, well, probably not a great value prop for you either. However, if you are somewhere in between, at least take a minute and check out a sample chapter from Roys book at: http://www.manning.com/osherove/.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • ResolveUrl() from WCF service

    - by Michael Freidgeim
    I wanted to ResolveUrl() from WCF service and foundhttp://www.west-wind.com/weblog/posts/2007/Sep/18/ResolveUrl-without-Page .However the function assumes that the call is synchronous, in asynchronous call (e.g called from TPL task) HttpContext.Current==null.I had to split my asynchronous method into two-a long asynchronous one, invoked as task and generating relative URL and a post-task, that is calling wwWebUtils.ResolveServerUrl(relativeUrL)The http://www.codeproject.com/Articles/205425/ASP-NET-ResolveUrl-Without-Page  article suggests to useSystem.Web.VirtualPathUtility.ToAbsolute("~/default.aspx");but i expect, it wouldn’t work from asynchronous thread as well.

  • What OpenGL version(s) to learn and/or use?

    - by zuko
    So, I'm new to OpenGL... I have general knowledge of game programming but little practical experience. I've been looking into various articles and books and trying to dive into OpenGL, but I've found the various versions and old vs new way of doing things confusing. I guess my first questions is does anyone know some figures about percentages of gamers that can run each version of OpenGL. What's the market share like? 2.x, 3.x, 4.x... I looked into the requirements for Half Life 2 since I know Valve updated it with OpenGL to run on Mac and I know they usually try to hit a very wide user-base, and they say a minimum of GeForce 8 Series. I looked at the 8800 GT on Nvidia's website and it listed support for OpenGL 2.1. Which, maybe I'm wrong, sounds ancient to me since there's already 4.x. I looked up a driver for 8800GT and it says it supports 4.2! A bit of a discrepancy there, lol. I've also read things like XP only supports up to a certain version, or OS X only supports 3.2, or all kinds of other things. Overall, I'm just confused as to how much support there is for various versions and what version to learn/use. I'm also looking for learning resources. My search results thus far have pointed me to the OpenGL SuperBible. The 4th edition has great reviews on Amazon, but it teaches 2.1. The 5th edition teaches 3.3 and there are a couple things in the reviews that mention the 4th edition is better and that the 5th edition doesn't properly teach the new features or something? Basically, even within learning material I'm seeing discrepancies and I just don't even know where to start. From what I understand, 3.x started a whole new way of doing things and I've read from various articles and reviews that you want to "stay away from deprecated features like glBegin(), glEnd()" yet a lot of books and tutorials I've seen use that method. I've seen people saying that, basically, the new way of doing stuff is more complicated yet the old way is bad . Just a side note, personally, I know I still have a lot to learn beforehand, but I'm interested in tessellation; so I guess that factors into it as well, because, as far as I understand that's only in 4.x? [just btw, my desktop supports 4.2]

  • How are people using virtualisation with SQL Server? Part 1

    - by GavinPayneUK
    Allow me to share with you the results of a survey I did about how people are using virtualisation with SQL Server. This is a three part series of articles sharing the results. In December 2010 I did a 10 question survey to see how people were using virtualisation with SQL Server and if they were changing their deployment and management processes as a result. 21 people responded from at least Europe, the US and Asia Pac. It’s not a massive number but it was large enough to see some trends and some...(read more)

  • Building a Store Locator ASP.NET Application Using Google Maps API

    The past couple of projects I've been working on have included the use of the Google Maps API and geocoding service in websites for various reasons. I decided to tie together some of the lessons learned, build an ASP.NETstore locator demo, and write about it on 4Guys. Last week I published the first article in what I think will be a three-part series: Building a Store Locator ASP.NET Application Using Google Maps (Part 1). Part 1 walks through creating a demo where a user can type in an address and any stores within a (roughly) 15 mile area will be displayed in a grid.The article begins with a look at the database used to power the store locator (namely, a single table that contains one row for every location, with each location storing its store number, address, and, most important, latitude and longitude coordinates) and then turns to usingGoogle's geocoding service to translatea user-entered address into latitude and longitude coordinates. The latitude and longitude coordinates are used to find nearby stores, which are then displayed in a grid. Part 2 looks at enhancing the search results to include a map with markers indicating the position of each nearby store location. The Google Maps API, along with a bit of client-side script and server-side logic, make this actually pretty straightforward and easy to implement. Here's a screen shot of the improved store locator results. Part 3, which I plan on publishing next week, looks at how to enhance the map by using information windows to display address information when clicking a marker. Additionally, I'll show how to use custom icons for the markers so that instead of having the same marker for each nearby location the markers will be images numbered 1, 2, 3, and so on, which will correspond to a number assigned to each search result in the grid. The idea here is that by numbering the search results in the grid and the markers on the map visitors will quickly be able to see what marker corresponds to what search result. This article and demo has been a lot of fun to write and create, and I hope you enjoy reading it, too.

  • The difference

    So with the CTP tools available, weve been building a few apps, just to get a feel for the tools and whats supported in the framework.  Whats been great is that everything is fairly familiar and consistent, largely to do with the .net framework and Microsofts focus on providing good tools.  Weve produced mobile applications, mostly in concept form, for Windows Phone Classic, iPhone and Android but never so quickly and not of such high quality and visual impression.  I attribute some of this obviously to our familiarity to the Microsoft platform and tools.  Though when you look at the designs our team has produced, it becomes clear that this is not just another mobile application container.                                                            The Metro design language implores content prominence with fluid motion and transitions, with a crisp font and easily organized features and services placement.  In addition to a purposeful right edge tease, where the intent is for users to discover new premium content and services.   The concept that enables this is called hubs, building application with hubs changes your thinking from a single mobile application task, to thinking creatively about a mobile experience. Its engaging to think of the other brands and industry verticals that will take advantage of this core feature.  Combine this with Windows Phone 7 live tiles, more on that later, and you have a recipe for a solid mobile services platform.                                                              This so much more fun and liberating than my icon on a gridDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • &quot;CLR Enabled&quot; is not required to use CLR built-ins

    - by AaronBertrand
    Books Online articles referencing built-in CLR functions (such as FORMAT() ) have a remark similar to the following: "FORMAT relies on the presence of .the .NET Framework Common Language Runtime (CLR)." A lot of people seem to interpret this as meaning: "You must enable the sp_configure option 'CLR enabled' in order to use FORMAT()." Some then go on and suggest you run code similar to the following before you play with these functions: EXEC sp_configure 'show advanced options' , 1 ; GO RECONFIGURE...(read more)
