• Unresolved symbol when inheriting interface

  - by LeopardSkinPillBoxHat

  It's late at night here and I'm going crazy trying to solve a linker error. If I have the following abstract interface: class IArpPacketBuilder { public: IArpPacketBuilder(const DslPortId& aPortId); virtual ~IArpPacketBuilder(); // Other abstract (pure virtual methods) here... }; and I instantiate it like this: class DummyArpPacketBuilder : public IArpPacketBuilder { public: DummyArpPacketBuilder(const DslPortId& aPortId) : IArpPacketBuilder(aPortId) {} ~DummyArpPacketBuilder() {} }; why am I getting the following error when linking? Unresolved symbol references: IArpPacketBuilder::IArpPacketBuilder(DslPortId const&): ppc603_vxworks/_arpPacketQueue.o IArpPacketBuilder::~IArpPacketBuilder(): ppc603_vxworks/_arpPacketQueue.o typeinfo for IArpPacketBuilder: ppc603_vxworks/_arpPacketQueue.o *** Error code 1 IArpPacketBuilder is an abstract interface, so as long as I define the constructors and destructions in the concrete (derived) interface, I should be fine, no? Well it appears not.

• Remove all references to a DLL across all application domains

  - by ck

  I have a web application that dynamically loads assemblies based on database configuration entries to perform certain actions (dynamic plugin style architecture). The calls to the objects are in a Factory Pattern implementation, and the object is cached (in a static dictionary< within the Factory) as the calls can be made many thousands of times in a minute. The calls to this factory are made from both the main web application and a number of webservices, some in different assemblies/projects. When I need to update one of these DLLs, I have to recycle IIS to get the DLL released. As this has an impact on another application on the server, I wanted to know if there was a way I could release the DLL without restarting IIS?

• Parsing dbpedia JSON in Python

  - by givp

  Hello, I'm trying to get my head around the dbpedia JSON schema and can't figure out an efficient way of extracting a specific node: This is what dbpedia gives me: http://dbpedia.org/data/Ceramic_art.json I've got the whole thing as a JSON object in Python but don't really understand how to get the english abstract from this data. I've gotten this far: u = "http://dbpedia.org/data/Ceramic_art.json" data = urlfetch.fetch(url=u) json_data = json.loads(data.content) for j in json_data["http://dbpedia.org/resource/Ceramic_art"]: if(j == "http://dbpedia.org/ontology/abstract"): print "it's here" Not sure how to proceed from here. As you can see there are multiple languages. I need to get the english abstract. Thanks for your help, g

• C# where keyword

  - by Carra

  Our Indian overseas developers have written the following piece of code (C# 2.0): public abstract class ObjectMapperBase<T> where T : new() { internal abstract bool UpdateObject(T plainObjectOrginal, T plainObjectNew, WebMethod fwm, IDbTransaction transaction); } Inheritor example: public abstract class OracleObjectMapperBase<T> : ObjectMapperBase<T> where T : new() { internal override bool UpdateObject(T plainObjectOrginal, T plainObjectNew, WebMethod fwm, IDbTransaction transaction) { //Fancy Reflection code } } I've never seen the where keyword before after the class name. What does this do?

• Address calling class

  - by Samuel

  I have an abstract class Moveable with the method abstract void move() which is extended by the class Bullet and the abstract class Character, and Character is extended by the class Survivor and the class Zombie. In Survivor and Bullet the move() method doesnt require any parameters while in the class Zombie the move() method depends on the actual position of the survivor. The survivor and multiple zombies are created in the class Gui. I wanted to access the survivor in Zombie - what's the best way of doing this? In Gui i wrote a method getSurvivor() but i don't see how to access this method in Zombie? I am aware that as a workaround i could just pass a [Survivor survivor] as parameter in move() and ignore it in Bullet and Survivor, but that feels so ... bad practice.

• grep only returns help text

  - by Pete Mancini

  Well, I am perplexed. I am working with an Ubuntu server and I type in grep 'bash' *.sh BUT fgrep 'bash' *.sh works like a champ. which grep and which fgrep both point to their respective executables in /bin. I am perplexed as to what I am doing wrong. EXAMPLE output: $ grep -F 'grounding' repl.clj Usage: grep [OPTION]... PATTERN [FILE]... Search for PATTERN in each FILE or standard input. PATTERN is, by default, a basic regular expression (BRE). Example: grep -i 'hello world' menu.h main.c $ fgrep 'grounding' repl.clj (p/concepts-for-grounding-term imp1 "PERSON" "summary") See? grep is failing but fgrep is working fine. That is why I am perplexed.

• C# - Why can't I enforce derived classes to have parameterless constructors?

  - by FrisbeeBen

  I am trying to do the following: public class foo<T> where T : bar, new { _t = new T(); private T _t; } public abstract class bar { public abstract void someMethod(); // Some implementation } public class baz : bar { public overide someMethod(){//Implementation} } And I am attempting to use it as follows: foo<baz> fooObject = new foo<baz>(); And I get an error explaining that 'T' must be a non-abstract type with a public parameterless constructor in order to use it as parameter 'T' in the generic type or method. I fully understand why this must be, and also understand that I could pass a pre-initialized object of type 'T' in as a constructor argument to avoid having to 'new' it, but is there any way around this? any way to enforce classes that derive from 'bar' to supply parameterless constructors?

• C# memory / allocation cleanup

  - by Number8

  Some near-code to try to illustrate the question, when are objects marked as available to be garbage-collected -- class ToyBox { public List<Toy> Toys = new List<Toy>(); } class Factory { public ToyBox GetToys() { ToyBox tb = new ToyBox(); tb.Toys.Add(new Toy()); tb.Toys.Add(new Toy()); return tb; } } main() { ToyBox tb = Factory.GetToys(); // After tb is used, does all the memory get cleaned up when tb goes out of scope? } Factory.GetToys() allocates memory. When is that memory cleaned up? I assume that when Factoy.GetToys() returns the ToyBox object, the only reference to the ToyBox object is the one in main(), so when that reference goes out of scope, the Toy objects and the ToyBox object are marked for garbage collection. Is that right? Thanks for any insights...

• Is it possible in Gnumeric to paste-special only background colors w/o overwriting foregroudn colors, boldness, etc?

  - by darenw

  I've written a huge complex spreadsheet in Gnumeric, with areas of different background and foreground colors, text and numbers in bold or various colors to indicate meanings. Certain cells ise a diagonal pattern combining the surrounding background color with black - this warns me not to alter those cells when I haven't had my morning coffee. Big problem is changing just the background color of an area - to do so wipes out boldness, foreground colors and the diagonal-pattern cells. I use "Paste Special" and choose Format to copy-paste colors from one area to another, or make the pattern of bold/normal of several rows match one that's done right. What I'd like "paste special - just the background colors (but preserve patterns and 2nd colors of backgrounds)" and "paste special - just the text style/fonts" but I've never encountered any such thing. Are the effects I want possible?

• Why are Java primitive types' modifiers `public`, `abstract`, & `final`?

  - by oconnor0

  In the process of doing some reflection on Java types, I came across an oddity that I do not understand. Inspecting int for its modifiers returns public, abstract, and final. I understand public and final, but the presence of abstract on a primitive type is non-obvious to me. Why is this the case? Edit: I am not reflecting on Integer but on int: import java.lang.reflect.Modifier; public class IntegerReflection { public static void main(final String[] args) { System.out.println(String.format("int.class == Integer.class -> %b", int.class == Integer.class)); System.out.println(String.format("int.class modifiers: %s", Modifier.toString(int.class.getModifiers()))); System.out.println(String.format("Integer.class modifiers: %s", Modifier.toString(Integer.class.getModifiers()))); } } The output when run: int.class == Integer.class -> false int.class modifiers: public abstract final Integer.class modifiers: public final

• Why does GetExportedValues<T>() no longer work after using the .net 4 final version of MEF?

  - by BigJason

  I have been developing a managed extensibility framework application for the last several months using the community preview. I have been using the GetExportedValues() method and the PartCreationPolicy(CreationPolicy.NonShared) to fake a class factory (since only the silverlight version supports a factory). This was working great until I upgraded the project to use .net 4.0. There is no error, it just doesn't work. So why did this code stop working? The code follows: The factory method: public static IEnumerable<DataActionBase> GetActionsFromDirectory(string PluginsFolder) { IEnumerable<DataActionBase> result = null; var catalog = new DirectoryCatalog(PluginsFolder); var container = new CompositionContainer(catalog: catalog); result = container.GetExportedValues<DataActionBase>(); return result; } Example Export Class: [Export(typeof(DataActionBase))] [PartCreationPolicy(CreationPolicy.NonShared)] public class AnAction : DataActionBase { .... }

• Why isn't the new() generic constraint satisfied by a class with optional parameters in the construc

  - by Joshua Flanagan

  The following code fails to compile, producing a "Widget must be a non-abstract type with a public parameterless constructor" error. I would think that the compiler has all of the information it needs. Is this a bug? An oversight? Or is there some scenario where this would not be valid? public class Factory<T> where T : new() { public T Build() { return new T(); } } public class Widget { public Widget(string name = "foo") { Name = name; } public string Name { get; set; } } public class Program { public static void Main() { var widget = new Widget(); // this is valid var factory = new Factory<Widget>(); // compiler error } }

• Spring MVC managing multiple views with single controller

  - by Sudhir

  I am trying to implement order management module. There are different order types (approximately about 15). Each order has a seperate view. But the actions performed on UI are same irrespective of order type. Below is the structure of my DTO abstract class Order abstract class SecurityOrder extends Order abstract class TermDepositOrder extends Order ..... ..... ..... I am trying to implement a single controller capable of managing all views. Something similar to the one below: @Controller public class OrderController<F extends Order> { public F validate(F order) { } public F insert(F order) { } } I am not sure how spring mvc would be able to map request parameters properly to the order instance as it doesn't know which order instance to populate. Is it possible to achieve this with single controller or should I go with a controller for each order type and duplicate same code across all controllers?

• Java: Best approach to have a long list of variables needed all the time without consuming memory?

  - by evilReiko

  I wrote an abstract class to contain all rules of the application because I need them almost everywhere in my application. So most of what it contains is static final variables, something like this: public abstract class appRules { public static final boolean IS_DEV = true; public static final String CLOCK_SHORT_TIME_FORMAT = "something"; public static final String CLOCK_SHORT_DATE_FORMAT = "something else"; public static final String CLOCK_FULL_FORMAT = "other thing"; public static final int USERNAME_MIN = 5; public static final int USERNAME_MAX = 16; // etc. } The class is big and contains LOTS of such variables. My Question: Isn't setting static variables means these variables are floating in memory all the time? Do you suggest insteading of having an abstract class, I have a instantiable class with non-static variables (just public final), so I instantiate the class and use the variables only when I need them. Or is what am I doing is completely wrong approach and you suggest something else?

• Part 2: Career development as a Software Developer without becoming a manager.

  - by albertpascual

  Seems like my previous post inspired by the work of Michael “Doc” Norton was a great success for the amount of emails I have received. Yet amazed how many people didn’t want to discuss their questions in the comments  sections. I would encourage people to be more public, still I would like to reply to all of you on this public media. I still welcome those emails. What I found out is that many people feels like me, they want to be developers and still be compensated for their experience without wanting to take a job as a manager. Their perfect day is a full day of coding and learning. Many believe their companies will never pay a manager’s salary to a developer no matter what. Most of you ask how to get the ball rolling. And is the later that I’m addressing here, the previous group, will never try. What companies understand developers value and where can I find them? This is a very difficult question to ask, I don’t have a list of those companies or departments, I have seen in my past signs in companies bending backwards to compensate, in more ways the monetary, a developer that is a good resource to them. Allowing the person to move out of the state and still let them work for the company from home is a sign that company goes by individual cases. Allowing them to go to conference that will not benefit the company is another big sign. Simple signs like flexible hours and letting some people work from home. To see those signs you need to be working in that company for awhile and look at the departments where the manager is taking care of their employees in individual cases. Look for the department where people get quiet extra perks, where some people in the department work from home or remotely. In my experience, but not always true, medium to big companies, are prompt to recognize good developers. Then again, some companies just don’t get it and is when you see many technical people managing developers. For all the people that email me stating that developers can also be very good managers, I do not disagree, I just think that a good developers loves writing code, when you remove that part the better salary isn’t enough to keep a developer happy. Burned out developers appreciate being promoted to managers. How do I know I work in a bad company? In my experience I have been a consultant and seen many companies, a few signs I have learned about companies that will not recognize good developers are: When the turn over is pretty high, when developers are moving out in a big rate, no rocket scientist needs to tap you in the shoulder. When the company is looking always to outsource their development resources. The product is not that interesting nor the company cares too much for their final result and support. Code sweat shops. You’ll know when you start working in one of those. Run for the hills! Where do I start? Disclaimer: I have only based this post on Michael “Doc” Norton, this is just my interpretation and ideas. First thing is to look at Michael “Doc” Norton presentation Take Control of Your Development Career http://docondev.blogspot.com/ That should be the first thing any developer should look and follow like it was a pattern. I would personally recommend to find some language or pattern you are interested with and learn it, learn something that will make you happy. Second, join a User Group and get involve in the community. There are hundreds of user groups, and I’m sure you’ll find one in your city or near you town. Code Camps are Developers Meet Ups are also good resources. Third, I would join a open source project you are interested or better yet, create a new open source project with the new technology that you have learn and get coding. Fourth, create a Twitter account and follow the people that talks about the technology you are interested on. If you follow this 4 steps above I think you’ll be on your way, after they are complete, when you release your Open Source project you can say that you accomplished the first steps. Now, do not expect anything to change in your career life, you are changing and should not expect anything in return, besides borrowing some time from sleeping and your family. Creating a good schedule may help you, I find wasted time in many places that I use. Flying for work is actually one of those that allows me to do my best work on a airplane, don’t need to borrow time from anywhere else. Making sure you always have a light, charged laptop is so important. Next steps following the Michael “Doc” Norton Pattern or my interpretation of. First, help run a user group or better yet, start a new user group. I’ll add, as well, go to one conference a year and free development events around your city; Code Camps, Geek Dinners, etc. There are many free events sponsored by different companies for developers to get to know their products, I highly recommend those as the way to get connected. Second, chose a mentor, this is a very hard thing to do I experienced, find an expert in the technology you are learning that has the time for you, it is difficult, I wish you best of luck. Third, learn another technology or pattern, open your horizons a little bit more. Why not, if you had fun previously, keep doing it. Fourth, get involved in forums to answer and ask questions, getting notice in public forums is rewarding for your ego after such a long journey. Final steps following the Michael “Doc” Norton Pattern Teach what you know, become humble on your knowledge, find as many opportunities to teach and to get involved with the community, bring all that to your day job. Mr. Norton talks about getting naked, expose yourself to others in your knowledge and what you do not know. You are never too important for small opportunities, yet don’t  be afraid to take anything big and learn from the experience. Anytime you have the opportunity to talk to somebody that has reach the point the community knows his or her name, means that you should learn from it. Take opportunities that won’t make you money, yet will make you happy. Sometimes you need to spend money and time. Register talks in Code Camps and Dev Meet Ups, those are free, also go to Conference, Development Summits and Geek Diners for example. One day, people will pay you to attend. When will all these pay off? I don’t know. I’m still in the path, there are a few things that during your journey you may get little acknowledgements that you are in the correct path. In my case I think those are the little signs that tells you about your journey. I got awarded the Microsoft Most Valuable Professional for ASP.NET in 2007, 2008, 2009 and 2010. I got selected to speak at the DevConnections in Las Vegas in 2010 and Orlando 2011. I do believe that I do have a long way to go, yet what I do makes me happy and I hope I can keep doing for years to come. Every year I can see an improvement on my code, and more frameworks and languages are under my belt, I learn to embrace them all as well as in my daily job, I have been able to work in a few projects beyond my department. I’m a learner and believer of the Michael “Doc” Norton pattern. Looking forward to learn more about it to be able to apply it better. In my short journey I now see my mistakes, I did a few things right, I have been listening the intelligent people and not being afraid to move along the technology changes. In my professional life, I have tried to avoid being placed in only one technology and product. I have always share my code and never confused anybody that wanted to take over any of my projects, I didn’t think anything I created as my own nor care too much when politics didn’t see my vision. I stayed flexible, ready and visible, yet humble. I keep my head just below the clouds, and avoided managers meetings. I credit my manager for my success, and I faulted publicly only myself for the failures. Hope this helps. Cheers, Al Follow me in Twitter  Read my previous post tweetmeme_url = 'http://weblogs.asp.net/albertpascual/archive/2010/12/09/part-2-career-development-as-a-software-developer-without-becoming-a-manager.aspx'; tweetmeme_source = 'alpascual';

• C# 4.0: Alternative To Optional Arguments

  - by Paulo Morgado

  Like I mentioned in my last post, exposing publicly methods with optional arguments is a bad practice (that’s why C# has resisted to having it, until now). You might argument that your method or constructor has to many variants and having ten or more overloads is a maintenance nightmare, and you’re right. But the solution has been there for ages: have an arguments class. The arguments class pattern is used in the .NET Framework is used by several classes, like XmlReader and XmlWriter that use such pattern in their Create methods, since version 2.0: XmlReaderSettings settings = new XmlReaderSettings(); settings.ValidationType = ValidationType.Auto; XmlReader.Create("file.xml", settings); With this pattern, you don’t have to maintain a long list of overloads and any default values for properties of XmlReaderSettings (or XmlWriterSettings for XmlWriter.Create) can be changed or new properties added in future implementations that won’t break existing compiled code. You might now argue that it’s too much code to write, but, with object initializers added in C# 3.0, the same code can be written like this: XmlReader.Create("file.xml", new XmlReaderSettings { ValidationType = ValidationType.Auto }); Looks almost like named and optional arguments, doesn’t it? And, who knows, in a future version of C#, it might even look like this: XmlReader.Create("file.xml", new { ValidationType = ValidationType.Auto });

• Wrong perspective is showing in Eclipse plugin project [closed]

  I am working in Eclipse Modeling Framework (Eclipse plugin development) in my project the tool(project i am working) provides three perspectives. 1.Accelerator Analyst perspective 2.Contract Validation and 3.Underwriter rules Editor...

As all perspective (Class, Id and Name) is define only inside Plugin.XML as it is the task of org.eclipse.ui.perspective that that perspective name should be come forefront.

• CQRS without using others patterns

  - by John Smith

  I would like to explain CQRS to my team of developers. I just can't figure out how to explain it in the simplest way so they can implement the pattern rapidly without any others frameworks. I've read a lot of resources including video and articles but I don't find how to implement CQRS without using others patterns like a service Bus, event sourcing pattern, domain driven design. I know the purpose of these pattern but for the first step, I don't want them to think CQRS and theses patterns must be tied together. My first idea is to say that CQRS is about separating the read part and the write part. The read part is composed only of the UI project, and DAL project. Then the write part is composed of a typical multilayer architecture: UI/BLL/DAL. Then, does CQRS say we must also have two datastore ? What about the notion of commands which reveal the user's intention, is it also something part of CQRS or DDD ? Basically, how to implement CQRS without using others patterns. I concede it's also not that clear in my mind because I've used to work with NCQRS/DDD/Event Sourcing/ServiceBus in my personal project. Thanks

• Developing a feature which sole purpose to be taken out?

  - by adib

  What is the name of the pattern in which individual contributors (programmers/designers) developed an artifact for the sole purpose is to serve as a diversion so that management can remove that feature in the final product? This is a folklore I heard from an ex-colleague who used to work at a large game development company. At that company, it is well known that middle management is pressurized to "give inputs" and "make changes" to the product otherwise they risk being seen as not contributing to the project. This situation have delayed many projects because of these superfluous "management inputs". In one project at the above company, the artists and developers created a supernumerary animated character that appears in every cutscene and sticks out like a sore thumb. They designed it in such a way that it can be easily removed before the game is shipped (this was when games were still sold in physical media and not a downloadable product). Obviously the management then voted to remove the animation. On the positive side, management didn't introduced any unnecessary changes that would have delayed the project because they have shown that they provided constructive inputs to the product. This process pattern has a name among game programmers that work in corporates, but I forgot what was the actual name. I believe it's duck-something. Anybody can help pointing out the name and perhaps some rather credible reference to how the pattern develops?.

• New features for Expression Blend 4 Release Candidate

  - by kaleidoscope

  With Microsoft Expression Blend 4, you can create websites and applications based on Microsoft Silverlight 3 and Microsoft Silverlight 4, and desktop applications based on Windows Presentation Foundation (WPF) 3.5 with Service Pack 1 (SP1) and WPF4. Expression Blend provides new support for prototyping, interactivity through behaviors, special Silverlight functionality, and on-the-fly sample data generation. Expression Blend includes new behaviors that are quickly and easily configured Expression Blend offers new sample data, behaviors, and features of project templates to support the Model-View-ViewModel (MVVM) pattern The MVVM pattern is a way to structure a Silverlight or WPF application so that user interface (UI) objects are as decoupled as possible from the application's data and behavior. This makes it easier for design tasks and development tasks to be performed independently and without breaking each other. Essentially, your UI is the View. You bind objects in the View to properties and commands of the ViewModel, and the View can also call methods on the ViewModel. Compatible with Silverlight 3 and WPF 3.5 with Service Pack 1 (SP1) Interoperate able with Visual Studio. Included New Shapes: The Assets panel in Expression Blend contains a new Shapes category, including presets for the easy creation of arcs, arrows, callouts, and polygons. New Controls: Expression Blend has tooling support for the RichTextBox control in Silverlight. XAML cleanliness :Expression Blend generates less XAML with respect to animations and animation-related properties. MVVM project template: Expression Blend includes a new project template that offers a basic starting point for Model-View-ViewModel pattern applications. Run project with CTRL+F5:To improve consistency with Visual Studio, you can now invoke the Run Project command by pressing either CTRL+F5 or F5 Technorati Tags: Rituraj,Features of Expression Blend4 RC
