• How to convince boss to buy Visual Studio 2012 Professional

  - by Sam Leach

  The main advantage is the use of ReSharper and other add-ons but we need to make a convincing argument for the purchase of Visual Studio 2012 Professional. We are currently using Visual Studio 2012 Express for Windows. It is quite good but is hard to switch from using the full Professional version in the past. So far the team has compiled the following list: Extract Interface function missing. Very useful for clean SOLID code. No add-on support. Can’t install StyleCop or productivity tools. AnkhSvn, Spell checker, Productivity PowerTools, GhostDoc, Regex Editor, PowerCommands. The exception assistant is limited in Express edition. This is a big annoyance. See http://www.lifehacker.com.au/2013/01/ive-given-up-on-visual-studio-express-2012-for-windows-desktop-heres-why/ Different tools provided by MS like certificate generation. Possibility of create a Test project based on source code. We do server development in C# so any web add-ons or anything else is useless. The reason I am asking is I am sure that people have been in the same position. What approach did you use and can you think of additions or ammends to the above list? Thanks,

• Why is Quicksort called "Quicksort"?

  - by Darrel Hoffman

  The point of this question is not to debate the merits of this over any other sorting algorithm - certainly there are many other questions that do this. This question is about the name. Why is Quicksort called "Quicksort"? Sure, it's "quick", most of the time, but not always. The possibility of degenerating to O(N^2) is well known. There are various modifications to Quicksort that mitigate this problem, but the ones which bring the worst case down to a guaranteed O(n log n) aren't generally called Quicksort anymore. (e.g. Introsort). I just wonder why of all the well-known sorting algorithms, this is the only one deserving of the name "quick", which describes not how the algorithm works, but how fast it (usually) is. Mergesort is called that because it merges the data. Heapsort is called that because it uses a heap. Introsort gets its name from "Introspective", since it monitors its own performance to decide when to switch from Quicksort to Heapsort. Similarly for all the slower ones - Bubblesort, Insertion sort, Selection sort, etc. They're all named for how they work. The only other exception I can think of is "Bogosort", which is really just a joke that nobody ever actually uses in practice. Why isn't Quicksort called something more descriptive, like "Partition sort" or "Pivot sort", which describe what it actually does? It's not even a case of "got here first". Mergesort was developed 15 years before Quicksort. (1945 and 1960 respectively according to Wikipedia) I guess this is really more of a history question than a programming one. I'm just curious how it got the name - was it just good marketing?

• DNS: forward part of a managed domain to one host, but sub domain services to another (Google Apps)

  - by Paul Zee

  I was going to post this as a comment against DNS: Forward domain to another host, but I don't seem able to do that. I'm in a similar situation. I have a DNS registered/managed by enom, except with the slight twist that the domain was originally registered with enom through a Google Apps account creation. The domain currently supports a Google Apps site/account. I now want to direct the bare primary domain and www entries to a hosting provider for the website component, but leave the Google Apps setup intact for its services such as calendar, mail etc. For now, I'm leaving the domain managed by enom. Also note that when I registered my account with the hosting provider, I gave the same domain name as the existing domain (e.g. example.com), so at their end I'm working with the same domain name in cpanel, etc. In my case, the existing enom DNS entries don't have an A record for the www.example.com, or the bare example.com domain. Instead, there are 4 x @ records with the Google Apps IP Address, 2 x TXT records with what I assume are Google Apps site verification strings/tokens, and a bunch of CNAME records for the various features of Google Apps (mail, calendar, docs, sites, etc). So, my questions: How do I point the www.example.com and example.com DNS entries at enom to my web site hosting provider, while leaving the domain managed by enom, and the Google Apps services working as they are now (with the obvious exception of Google Sites)? How do I setup the example.com mail-related DNS records (MX, etc) at the web site hosting provider, so that outbound email to [email protected] gets correctly sent to the google apps mail account, and doesn't get trapped inside the pseudo domain within the hosting providers servers?

The key to successfully managing such an environment is middleware, and BI and EPM become increasingly middleware intensive. In fact, given the horizontal nature of BI and EPM, sitting on top of all business functions and applications, you could call them 'upperware.'" -- Frank Buytendijk (tags: oracle otn enterprisearchitecture bi)

• How to fix Failed to initialize Windows Azure storage emulator error

  - by ybbest

  When you press F5 to start debugging Azure project, you might get the following exception: If you go to the Output windows, you will see the detailed error message below: Windows Azure Tools: Failed to initialize Windows Azure storage emulator. Unable to start Development Storage. Failed to start Development Storage: the SQL Server instance ‘localhost\SQLExpress’ could not be found. Please configure the SQL Server instance for Development Storage using the ‘DSInit’ utility in the Windows Azure SDK. This is because by default, Azure uses the SQLExpress to start Development Storage. To fix this you can do the following: You need to open command prompt, and navigate to C:\Program Files\Windows Azure SDK\v1.4\bin\devstore (depending on your Azure version, the file path is slightly different.) Next, run DSInit /sqlInstance:. (. Means the SQL Server use the default instance, if you have name instance, you need to change. to the name of the SQL Server) After a short while, you should see the following windows showing the configuration succeeds. You can download a batch file here. References: http://msdn.microsoft.com/en-us/library/gg433132.aspx

• Difference between sh file.sh and file.sh

  - by RAS

  I have two questions : What is the difference between executing sh filename.sh and filename.sh? How can I make both of them giving me the same output ? I'm asking this question as right now I'm facing a problem. I'm trying to run a Java + SWT application from terminal. When I do filename.sh, it gives me the desired output. But when I do sh filename.sh or bash filename.sh, it throws me an error : Exception in thread "main" java.lang.NoClassDefFoundError: MainForm/java Caused by: java.lang.ClassNotFoundException: MainForm.java at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) Could not find the main class: MainForm.java. Program will exit. I know this question is already asked here but I'm still not clear about it. I have gone through the following links : What is the difference between ./ and sh to run a script? Can scripts run even when they are not set as executable? Can anyone help me with this?

• Java HttpURLConnection class Program

  - by pandu

  I am learning java. Here is the sample code of HttpURLConnection class usage in some text book import java.net.*; import java.io.*; import java.util.*; class HttpURLDemo { public static void main(String args[]) throws Exception { URL hp = new URL("http://www.google.com"); HttpURLConnection hpCon = (HttpURLConnection) hp.openConnection(); // Display request method. System.out.println("Request method is " + hpCon.getRequestMethod()); // Display response code. System.out.println("Response code is " + hpCon.getResponseCode()); // Display response message. System.out.println("Response Message is " + hpCon.getResponseMessage()); // Get a list of the header fields and a set // of the header keys. Map<String, List<String>> hdrMap = hpCon.getHeaderFields(); Set<String> hdrField = hdrMap.keySet(); System.out.println("\nHere is the header:"); // Display all header keys and values. for(String k : hdrField) { System.out.println("Key: " + k + " Value: " + hdrMap.get(k)); } } } Question is Why hpCon Object is declared in the following way? HttpURLConnection hpCon = (HttpURLConnection) hp.openConnection(); instead of declaring like this HttpURLConnection hpCon = new HttpURLConnection(); Author provided the following explanation. I cant understand Java provides a subclass of URLConnection that provides support for HTTP connections. This class is called HttpURLConnection. You obtain an HttpURLConnection in the same way just shown, by calling openConnection( ) on a URL object, but you must cast the result to HttpURLConnection. (Of course, you must make sure that you are actually opening an HTTP connection.) Once you have obtained a reference to an HttpURLConnection object, you can use any of the methods inherited from URLConnection

• Open Source Security packages for Rails

  - by Edwin

  I'm currently creating a complete web application using Rails 3 to familiarize myself with its inner workings and to gain a better appreciation of a working web application's moving parts. (Plus, since I'm still working on my degree, I hope that it will give me a better idea of what's BS in my education requirements and which weaknesses/skills I should focus on.) The example application I'm working on is an ecommerce site, and I've already configured the backend, routes, controllers, and so on. As part of the application, I'd like to integrate a second layer of security on top of the one Rails already provides for user authentication. However, I've been unable to find any on Google, with the exception of OAuth - which, from my understanding, is meant to secure API calls. While I could roll my own secure authentication system, I'm only in my second year of college and recognize that A) I know little about security, and B) there are developers that know much more about security that are working on open-source projects. What are some actively developed open-source security packages or frameworks that can be easily added to Rails? Pros and cons are not necessary, as I can do the research myself. P.S. I'm not sure whether I posted this in the right SE site; please migrate to SO or Security if it is more appropriate there.

• LWJGL SlickUtil Texture Binding

  - by Matthew Dockerty

  I am making a 3D game using LWJGL and I have a texture class with static variables so that I only need to load textures once, even if I need to use them more than once. I am using Slick Util for this. When I bind a texture it works fine, but then when I try to render something else after I have rendered the model with the texture, the texture is still being bound. How do I unbind the texture and set the rendermode to the one that was in use before any textures were bound? Some of my code is below. The problem I am having is the player texture is being used in the box drawn around the player after it the model has been rendered. Model.java public class Model { public List<Vector3f> vertices = new ArrayList<Vector3f>(); public List<Vector3f> normals = new ArrayList<Vector3f>(); public ArrayList<Vector2f> textureCoords = new ArrayList<Vector2f>();

• Team Foundation Server 2012 Build Global List Problems

  - by Bob Hardister

  My experience with the upgrade and use of TFS 2012 has been very positive. I did come across a couple of issues recently that tripped things up for a while. ISSUE 1 The first issue is that 2012 prior to Update 1 published an invalid build list item value to the collection global list. In 2010, the build global list, list item value syntax is an underscore between the build definition and the build number. In the 2012 RTM this underscore was replaced with a backslash, which is invalid.  Specifically, an upload of the global list fails when the backslash is followed at some point by a period. The error when using the API is: <detail ExceptionMessage="TF26204: The account you entered is not recognized. Contact your Team Foundation Server administrator to add your account." BaseExceptionName="Microsoft.TeamFoundation.WorkItemTracking.Server.ValidationException"><details id="600019" http://schemas.microsoft.com/TeamFoundation/2005/06/WorkItemTracking/faultdetail/03"http://schemas.microsoft.com/TeamFoundation/2005/06/WorkItemTracking/faultdetail/03" /></detail> when uploading the global list via the process editor the error is: This issue is corrected in Update1 as the backslash is changed to a forward slash. ISSUE 2 The second issue is that when upgrading from 2010 to 2012, the builds in 2010 are not published to the 2012 global list.  After the upgrade the 2012 global lists doesn’t have any builds and only builds run in 2012 are published to the global list. This was reported to the MSDN forums and Connect. To correct this I wrote a utility to pull all the builds and recreate the builds global list for each project in each collection.  This is a console application with a program.cs, a globallists.cs and a app.config (not published here). The utility connects to TFS 2012, loops through the collections or a target collection as specified in the app.config. Then loops through the projects, the build definitions, and builds.  It creates a global list for each project if that project has at least one build. Then it imports the new list to TFS.  Here’s the code for program and globalists classes. Program.CS using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.TeamFoundation.Framework.Client; using Microsoft.TeamFoundation.Framework.Common; using Microsoft.TeamFoundation.Client; using Microsoft.TeamFoundation.Server; using System.IO; using System.Xml; using Microsoft.TeamFoundation.WorkItemTracking.Client; using System.Diagnostics; using Utilities; using System.Configuration; namespace TFSProjectUpdater_CLC { class Program { static void Main(string[] args) { DateTime temp_d = System.DateTime.Now; string logName = temp_d.ToShortDateString(); logName = logName.Replace("/", "_"); logName = logName + "_" + temp_d.TimeOfDay; logName = logName.Replace(":", "."); logName = "TFSGlobalListBuildsUpdater_" + logName + ".log"; Trace.Listeners.Add(new TextWriterTraceListener(Path.Combine(ConfigurationManager.AppSettings["logLocation"], logName))); Trace.AutoFlush = true; Trace.WriteLine("Start:" + DateTime.Now.ToString()); Console.WriteLine("Start:" + DateTime.Now.ToString()); string tfsServer = ConfigurationManager.AppSettings["TargetTFS"].ToString(); GlobalLists gl = new GlobalLists(); //replace this with the URL to your TFS instance.

• WSDL-world vs CLR-world – some differences

  - by nmarun

  A change in mindset is required when switching between a typical CLR application and a web service application. There are some things in a CLR environment that just don’t add-up in a WSDL arena (and vice-versa). I’m listing some of them here. When I say WSDL-world, I’m mostly talking with respect to a WCF Service and / or a Web Service. No (direct) Method Overloading: You definitely can have overloaded methods in a, say, Console application, but when it comes to a WCF / Web Services application, you need to adorn these overloaded methods with a special attribute so the service knows which specific method to invoke. When you’re working with WCF, use the Name property of the OperationContract attribute to provide unique names. 1: [OperationContract(Name = "AddInt")] 2: int Add(int arg1, int arg2); 3:  4: [OperationContract(Name = "AddDouble")] 5: double Add(double arg1, double arg2); By default, the proxy generates the code for this as: 1: [System.ServiceModel.OperationContractAttribute( 2: Action="http://tempuri.org/ILearnWcfService/AddInt", 3: ReplyAction="http://tempuri.org/ILearnWcfService/AddIntResponse")] 4: int AddInt(int arg1, int arg2); 5: 6: [System.ServiceModel.OperationContractAttribute( 7: Action="http://tempuri.org/ILearnWcfServiceExtend/AddDouble", 8: ReplyAction="http://tempuri.org/ILearnWcfServiceExtend/AddDoubleResponse")] 9: double AddDouble(double arg1, double arg2); With Web Services though the story is slightly different. Even after setting the MessageName property of the WebMethod attribute, the proxy does not change the name of the method, but only the underlying soap message changes. 1: [WebMethod] 2: public string HelloGalaxy() 3: { 4: return "Hello Milky Way!"; 5: } 6:  7: [WebMethod(MessageName = "HelloAnyGalaxy")] 8: public string HelloGalaxy(string galaxyName) 9: { 10: return string.Format("Hello {0}!", galaxyName); 11: } The one thing you need to remember is to set the WebServiceBinding accordingly. 1: [WebServiceBinding(ConformsTo = WsiProfiles.None)] The proxy is: 1: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/HelloGalaxy", 2: RequestNamespace="http://tempuri.org/", 3: ResponseNamespace="http://tempuri.org/", 4: Use=System.Web.Services.Description.SoapBindingUse.Literal, 5: ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] 6: public string HelloGalaxy() 7:  8: [System.Web.Services.WebMethodAttribute(MessageName="HelloGalaxy1")] 9: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/HelloAnyGalaxy", 10: RequestElementName="HelloAnyGalaxy", 11: RequestNamespace="http://tempuri.org/", 12: ResponseElementName="HelloAnyGalaxyResponse", 13: ResponseNamespace="http://tempuri.org/", 14: Use=System.Web.Services.Description.SoapBindingUse.Literal, 15: ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] 16: [return: System.Xml.Serialization.XmlElementAttribute("HelloAnyGalaxyResult")] 17: public string HelloGalaxy(string galaxyName) 18:  You see the calling method name is the same in the proxy, however the soap message that gets generated is different. Using interchangeable data types: See details on this here. Type visibility: In a CLR-based application, if you mark a field as private, well we all know, it’s ‘private’. Coming to a WSDL side of things, in a Web Service, private fields and web methods will not get generated in the proxy. In WCF however, all your operation contracts will be public as they get implemented from an interface. Even in case your ServiceContract interface is declared internal/private, you will see it as a public interface in the proxy. This is because type visibility is a CLR concept and has no bearing on WCF. Also if a private field has the [DataMember] attribute in a data contract, it will get emitted in the proxy class as a public property for the very same reason. 1: [DataContract] 2: public struct Person 3: { 4: [DataMember] 5: private int _x; 6:  7: [DataMember] 8: public int Id { get; set; } 9:  10: [DataMember] 11: public string FirstName { get; set; } 12:  13: [DataMember] 14: public string Header { get; set; } 15: } 16: } See the ‘_x’ field is a private member with the [DataMember] attribute, but the proxy class shows as below: 1: [System.Runtime.Serialization.DataMemberAttribute()] 2: public int _x { 3: get { 4: return this._xField; 5: } 6: set { 7: if ((this._xField.Equals(value) != true)) { 8: this._xField = value; 9: this.RaisePropertyChanged("_x"); 10: } 11: } 12: } Passing derived types to web methods / operation contracts: Once again, in a CLR application, I can have a derived class be passed as a parameter where a base class is expected. I have the following set up for my WCF service. 1: [DataContract] 2: public class Employee 3: { 4: [DataMember(Name = "Id")] 5: public int EmployeeId { get; set; } 6:  7: [DataMember(Name="FirstName")] 8: public string FName { get; set; } 9:  10: [DataMember] 11: public string Header { get; set; } 12: } 13:  14: [DataContract] 15: public class Manager : Employee 16: { 17: [DataMember] 18: private int _x; 19: } 20:  21: // service contract 22: [OperationContract] 23: Manager SaveManager(Employee employee); 24:  25: // in my calling code 26: Manager manager = new Manager {_x = 1, FirstName = "abc"}; 27: manager = LearnWcfServiceClient.SaveManager(manager); The above will throw an exception saying: In short, this is saying, that a Manager type was found where an Employee type was expected! Hierarchy flattening of interfaces in WCF: See details on this here. In CLR world, you’ll see the entire hierarchy as is. That’s another difference. Using ref parameters: * can use ref for parameters, but operation contract should not be one-way (gives an error when you do an update service reference)   => bad programming; create a return object that is composed of everything you need! This one kind of stumped me. Not sure why I tried this, but you can pass parameters prefixed with ref keyword* (* terms and conditions apply). The main issue is this, how would we know the changes that were made to a ‘ref’ input parameter are returned back from the service and updated to the local variable? Turns out both Web Services and WCF make this tracking happen by passing the input parameter in the response soap. This way when the deserializer does its magic, it maps all the elements of the response xml thereby updating our local variable. Here’s what I’m talking about. 1: [WebMethod(MessageName = "HelloAnyGalaxy")] 2: public string HelloGalaxy(ref string galaxyName) 3: { 4: string output = string.Format("Hello {0}", galaxyName); 5: if (galaxyName == "Andromeda") 6: { 7: galaxyName = string.Format("{0} (2.5 million light-years away)", galaxyName); 8: } 9: return output; 10: } This is how the request and response look like in soapUI. As I said above, the behavior is quite similar for WCF as well. But the catch comes when you have a one-way web methods / operation contracts. If you have an operation contract whose return type is void, is marked one-way and that has ref parameters then you’ll get an error message when you try to reference such a service. 1: [OperationContract(Name = "Sum", IsOneWay = true)] 2: void Sum(ref double arg1, ref double arg2); 3:  4: public void Sum(ref double arg1, ref double arg2) 5: { 6: arg1 += arg2; 7: } This is what I got when I did an update to my service reference: Makes sense, because a OneWay operation is… one-way – there’s no returning from this operation. You can also have a one-way web method: 1: [SoapDocumentMethod(OneWay = true)] 2: [WebMethod(MessageName = "HelloAnyGalaxy")] 3: public void HelloGalaxy(ref string galaxyName) This will throw an exception message similar to the one above when you try to update your web service reference. In the CLR space, there’s no such concept of a ‘one-way’ street! Yes, there’s void, but you very well can have ref parameters returned through such a method. Just a point here; although the ref/out concept sounds cool, it’s generally is a code-smell. The better approach is to always return an object that is composed of everything you need returned from a method. These are some of the differences that we need to bear when dealing with services that are different from our daily ‘CLR’ life.

• SDL & Windows 8 Metro WinRT

  - by Adrian

  I am just beginning to dip my tow into game programming and have been reading up on SDL, SFML, OpenGL, XNA, MonoGame and of course DirectX. (Needless to say there are a lot of choices out there) As much as I like SFMLs syntax I have chosen to read up and start with SDL as it is pretty ubiquitous and available on every platform (Windows, Linux, Mac) and also available on portable devices (Android, iOS) with the current exception of WinPhone 7 After that pre-amble here is my question. I notice that the docs say that for the windows platform the SDL API calls through to DirectX for higher perf. ( http://www.libsdl.org/intro.en/whatplatforms.html ) Microsoft have said that for Metro Game Apps you can only use DirectX (which means no XNA, no OpenGL, no SFML, etc, etc) My question is: If SDL just wraps DirectX calls will I (we) be able to use SDL to bring games to the new Metro WinRT environment and Windows 8 marketplace? This would be great if possible. Additionally as WinPhone 8 is supposedly built on Win8 then this could mean SDL would be available on the win phone in the future too. Thanks for your time in responding to this question and I look forward to hearing your response. EDIT: Based on DeadMG's answer I have installed Visual Studio 11 (beta) in Windows 8 Consumer Preview (CP) and went file-New to check project types. The project types: "Blank Application", "Direct2D Application" and "Direct3D Application" look of interest. I have selected "Direct2D App" but SDL generates its own window when you call: SDL_INIT Is it possible to link/setup the SDL window to point to the Direct2D surface in the this project?

• How do I load tmx files with Slick2d?

  - by mbreen

  I just started using Slick2D and learned how simple it is to load in a tilemap and display it. I tried atleast a dozen different tmx files from numerous examples to see if it was the actual file that was corrupted. Everytime I get this error: Exception in thread "main" java.lang.RuntimeException: Resource not found: data/maps/desert.tmx at org.newdawn.slick.util.ResourceLoader.getResourceAsStream(ResourceLoader.java:69) at org.newdawn.slick.tiled.TiledMap.<init>(TiledMap.java:101) at game.Game.init(Game.java:17) at game.Tunneler.initStatesList(Tunneler.java:37) at org.newdawn.slick.state.StateBasedGame.init(StateBasedGame.java:164) at org.newdawn.slick.AppGameContainer.setup(AppGameContainer.java:390) at org.newdawn.slick.AppGameContainer.start(AppGameContainer.java:314) at game.Tunneler.main(Tunneler.java:29) Here is my Game class: package game; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.SlickException; import org.newdawn.slick.state.BasicGameState; import org.newdawn.slick.state.StateBasedGame; import org.newdawn.slick.tiled.TiledMap; public class Game extends BasicGameState{ private int stateID = -1; private TiledMap map = null; public Game(int stateID){ this.stateID = stateID; } public void init(GameContainer container, StateBasedGame game) throws SlickException{ map = new TiledMap("data/maps/desert.tmx","maps");//ERROR } public void render(GameContainer container, StateBasedGame game, Graphics g) throws SlickException{ //map.render(0,0); } public void update(GameContainer container, StateBasedGame game, int delta) throws SlickException{ } public int getID(){return stateID;} } I've tried to see if anyone else has had similar problems but haven't turned up anything. I am able to load other files, so I don't believe it's a compiler issue. My menu class can load images and display them just fine. Also, the filepath is correct. Please let me know if you have any pointers that might help me sort this out.

• Should certain math classes be required for a Computer Science degree?

  - by sunpech

  For a Computer Science (CS) degree at many colleges and universities, certain math courses are required: Calculus, Linear Algebra, and Discrete Mathematics are few examples. However, since I've started working in the real world as a software developer, I have yet to truly use some the knowledge I had at once acquired from taking those classes. Discrete Math might be the only exception. My questions: Should these math classes be required to obtain a computer science degree? Or would they be better served as electives? I'm challenging even that the certain math classes even help with required CS classes. For example, I never used linear algebra outside of the math class itself. I hear it's used in Computer Graphics, but I never took those classes-- yet linear algebra was required for a CS degree. I personally think it could be better served as an elective rather than requirement because it's more specific to a branch of CS rather than general CS. From a Slashdot post CS Profs Debate Role of Math In CS Education: 'For too long, we have taught computer science as an academic discipline (as though all of our students will go on to get PhDs and then become CS faculty members) even though for most of us, our students are overwhelmingly seeking careers in which they apply computer science.'

• Reflector – The King is Dead. Long Live the King.

  - by Sean Feldman

  There was enough of responses for Red Gate announcement about free version of .NET Reflector. Neither there’s a need to explain how useful the tool is for almost any .NET developer. There were a lot of talks about the price – $35 is it something to make noise about or just accept it and move on. Honestly, I couldn’t make my mind and was sitting on a fence. Today I learned some really exciting news – two (not one), two different initiatives to replace Reflector. A completely free ILSpy from SharpDevelop Commercial later to be stand-alone free decompiler tool from JetBrains These are great news. First – ILSpy is already doing what I need – you can download it and start using. Having experience with a few projects from SharpDevelop I believe it will be a great tool to have. One of immediate things that I found is reflecting obfuscated assemblies. Reflector blows up and closes, where ILSpy takes it gracefully and just shows an exception with no additional popup windows. JetBrains – company I highly respect. This is the case where I would continue paying money for their product and get more productivity. I am heavily relying on R# to do my job, and having a reflecting option would only add oil into fire of convincing others to use the tool. Though what I was excited was the statement JetBrains boldly put out: …it’s going to be released this year, and it’s going to be free of charge. And by saying “free”, we actually mean “free”.

• Extreme Optimization Numerical Libraries for .NET – Part 1 of n

  - by JoshReuben

  While many of my colleagues are fascinated in constructing the ultimate ViewModel or ServiceBus, I feel that this kind of plumbing code is re-invented far too many times – at some point in the near future, it will be out of the box standard infra. How many times have you been to a customer site and built a different variation of the same kind of code frameworks? How many times can you abstract Prism or reliable and discoverable WCF communication? As the bar is raised for whats bundled with the framework and more tasks become declarative, automated and configurable, Information Systems will expose a higher level of abstraction, forcing software engineers to focus on more advanced computer science and algorithmic tasks. I've spent the better half of the past decade building skills in .NET and expanding my mathematical horizons by working through the Schaums guides. In this series I am going to examine how these skillsets come together in the implementation provided by ExtremeOptimization. Download the trial version here: http://www.extremeoptimization.com/downloads.aspx Overview The library implements a set of algorithms for: linear algebra, complex numbers, numerical integration and differentiation, solving equations, optimization, random numbers, regression, ANOVA, statistical distributions, hypothesis tests. EONumLib combines three libraries in one - organized in a consistent namespace hierarchy. Mathematics Library - Extreme.Mathematics namespace Vector and Matrix Library - Extreme.Mathematics.LinearAlgebra namespace Statistics Library - Extreme.Statistics namespace System Requirements -.NET framework 4.0  Mathematics Library The classes are organized into the following namespace hierarchy: Extreme.Mathematics – common data types, exception types, and delegates.

• null pointers vs. Null Object Pattern

  - by GlenH7

  Attribution: This grew out of a related P.SE question My background is in C / C++, but I have worked a fair amount in Java and am currently coding C#. Because of my C background, checking passed and returned pointers is second-hand, but I acknowledge it biases my point of view. I recently saw mention of the Null Object Pattern where the idea is than an object is always returned. Normal case returns the expected, populated object and the error case returns empty object instead of a null pointer. The premise being that the calling function will always have some sort of object to access and therefore avoid null access memory violations. So what are the pros / cons of a null check versus using the Null Object Pattern? I can see cleaner calling code with the NOP, but I can also see where it would create hidden failures that don't otherwise get raised. I would rather have my application fail hard (aka an exception) while I'm developing it than have a silent mistake escape into the wild. Can't the Null Object Pattern have similar problems as not performing a null check? Many of the objects I have worked with hold objects or containers of their own. It seems like I would have to have a special case to guarantee all of the main object's containers had empty objects of their own. Seems like this could get ugly with multiple layers of nesting.
