• Definition of the job titles involved in a software development process.

  - by Rafael Romão

  I have seen many job titles for people involved in a software development process, but never found a consensus about they mean. I know many of them are equivalent, and found some other questions about that here in SO, but I would like to know your definitions and comments about them. I want not only to know if there is really a consensus, but also to know if what I suppose to be a Software Architect, is really a Software Architect, and so on. The job titles I mean are: Developer; System Analyst; Programmer; Analyst Programmer; Software Engineer; Software Architect; Designer; Software Designer; Business Manager; Business Analyst; Program Manager; Project Manager; Development Manager; Tester; Support Analyst; Please, feel free to add more titles to this list in your answers. It would be very helpful.

• Gallio MbUnit and Team City problem

  - by Bernard Larouche

  I asked a question this morning about an integration problem between Gallio and Team City. I changed the msbuild file to use the proper syntax with the latest Gallio build script API. Thank you for that Jeff Brown but now when I tried to build the application on Team City I get the following error : An unexpected error occurred during execution of the Gallio task.[16:19:49]: [Project "CoderForTraders.msbuild.teamcity.patch.tcprojx" (RebuildSolution;RunTests target(s)):] C:\TeamCity\buildAgent\work\fa1d38b0af329d65\CoderForTraders.msbuild(9, 9): FilterParseException: Colon expected Here's line 9 : <Gallio IgnoreFailures="true" Filter="Type=SomeFixture" Files="@(TestFile)"> and here is the whole file : <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <!-- This is needed by MSBuild to locate the Gallio task --> <UsingTask AssemblyFile="C:\Gallio\bin\Gallio.MSBuildTasks.dll" TaskName="Gallio" /> <!-- Specify the test files and assemblies --> <ItemGroup> <TestFile Include="C:\_CBL\CBL\CoderForTraders\Source\trunk\UnitTest\DomainModel.Tests\bin\Debug\CBL.CoderForTraders.DomainModel.Tests.dll" /> </ItemGroup> <Target Name="RunTests"> <Gallio IgnoreFailures="true" Filter="Type=SomeFixture" Files="@(TestFile)"> <!-- This tells MSBuild to store the output value of the task's ExitCode property into the project's ExitCode property --> <Output TaskParameter="ExitCode" PropertyName="ExitCode"/> </Gallio> <Error Text="Tests execution failed" Condition="'$(ExitCode)' != 0" /> </Target> <Target Name="RebuildSolution"> <Message Text="Starting to Build"/> <MSBuild Projects="CoderForTraders.sln" Properties="Configuration=Debug" Targets="Rebuild" /> </Target> </Project> Do you have an idea about the possible problem ?

• How to avoid XCode framework weak-linking problems?

  - by Frank R.

  Hi, I'm building an application that takes advantage of Mac OS X 10.6-only technologies, but without giving up backwards compatibility to 10.5 Leopard. The way I do this is by setting the 10.6 SDK as the base SDK, weak-linking all frameworks and setting the deployment target to 10.5 as described in: http://developer.apple.com/mac/library/DOCUMENTATION/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html This works fine; before making a call that is Snow Leopard-only I need to check that the selector or indeed the class actually exist. Or I can just check the OS version before making the call. The problem is that this is incredibly fragile. If I make a single call that is 10.6 only I blow Leopard-compatibility. So using even the normal code code completion feature can be dangerous. My question: is there any way of checking which calls are not defined on 10.5 before doing a release build? Some kind of static analysis, or even just a trick (a target set the other SDK?) would do. I obviously should test on a Leopard machine before releasing anything, but even so I can't possibly go through all paths of the program before every release. Any advice would be appreciated. Best regards, Frank

• Indy Write Buffering / Efficient TCP communication

  - by Smasher

  I know, I'm asking a lot of questions...but as a new delphi developer I keep falling over all these questions :) This one deals with TCP communication using indy 10. To make communication efficient, I code a client operation request as a single byte (in most scenarios followed by other data bytes of course, but in this case only one single byte). Problem is that var Bytes : TBytes; ... SetLength (Bytes, 1); Bytes [0] := OpCode; FConnection.IOHandler.Write (Bytes, 1); ErrorCode := Connection.IOHandler.ReadByte; does not send that byte immediately (at least the servers execute handler is not invoked). If I change the '1' to a '9' for example everything works fine. I assumed that Indy buffers the outgoing bytes and tried to disable write buffering with FConnection.IOHandler.WriteBufferClose; but it did not help. How can I send a single byte and make sure that it is immediatly sent? And - I add another little question here - what is the best way to send an integer using indy? Unfortunately I can't find function like WriteInteger in the IOHandler of TIdTCPServer...and WriteLn (IntToStr (SomeIntVal)) seems not very efficient to me. Does it make a difference whether I use multiple write commands in a row or pack things together in a byte array and send that once? Thanks for any answers! EDIT: I added a hint that I'm using Indy 10 since there seem to be major changes concerning the read and write procedures.

• What are some strategies for maintaining a common database schema with a team of developers and no D

  - by Mahmoud Abdelkader

  I'm curious about how others have approached the problem of maintaining and synchronizing database changes across many (10+) developers without a DBA? What I mean, basically, is that if someone wants to make a change to the database, what are some strategies to doing that? (i.e. I've created a 'Car' model and now I want to apply the appropriate DDL to the database, etc..) We're primarily a Python shop and our ORM is SQLAlchemy. Previously, we had written our models in such a way to create the models using our ORM, but we recently ditched this because: We couldn't track changes using the ORM The state of the ORM wasn't in sync with the database (e.g. lots of differences primarily related to indexes and unique constraints) There was no way to audit database changes unless the developer documented the database change via email to the team. Our solution to this problem was to basically have a "gatekeeper" individual who checks every change into the database and applies all accepted database changes to an accepted_db_changes.sql file, whereby the developers who need to make any database changes put their requests into a proposed_db_changes.sql file. We check this file in, and, when it's updated, we all apply the change to our personal database on our development machine. We don't create indexes or constraints on the models, they are applied explicitly on the database. I would like to know what are some strategies to maintain database schemas and if ours is seems reasonable. Thanks!

• Create System.Data.Linq.Table in Code for Testing

  - by S. DePouw

  I have an adapter class for Linq-to-Sql: public interface IAdapter : IDisposable { Table<Data.User> Activities { get; } } Data.User is an object defined by Linq-to-Sql pointing to the User table in persistence. The implementation for this is as follows: public class Adapter : IAdapter { private readonly SecretDataContext _context = new SecretDataContext(); public void Dispose() { _context.Dispose(); } public Table<Data.User> Users { get { return _context.Users; } } } This makes mocking the persistence layer easy in unit testing, as I can just return whatever collection of data I want for Users (Rhino.Mocks): Expect.Call(_adapter.Users).Return(users); The problem is that I cannot create the object 'users' since the constructors are not accessible and the class Table is sealed. One option I tried is to just make IAdapter return IEnumerable or IQueryable, but the problem there is that I then do not have access to the methods ITable provides (e.g. InsertOnSubmit()). Is there a way I can create the fake Table in the unit test scenario so that I may be a happy TDD developer?

• What are some Java memory management best practices?

  - by Ascalonian

  I am taking over some applications from a previous developer. When I run the applications through Eclipse, I see the memory usage and the heap size increase a lot. Upon further investigation, I see that they were creating an object over-and-over in a loop as well as other things. I started to go through and do some clean up. But the more I went through, the more questions I had like "will this actually do anything?" For example, instead of declaring a variable outside the loop mentioned above and just setting its value in the loop... they created the object in the loop. What I mean is: for(int i=0; i < arrayOfStuff.size(); i++) { String something = (String) arrayOfStuff.get(i); ... } versus String something = null; for(int i=0; i < arrayOfStuff.size(); i++) { something = (String) arrayOfStuff.get(i); } Am I incorrect to say that the bottom loop is better? Perhaps I am wrong. Also, what about after the second loop above, I set "something" back to null? Would that clear out some memory? In either case, what are some good memory management best practices I could follow that will help keep my memory usage low in my applications? Update: I appreciate everyones feedback so far. However, I was not really asking about the above loops (although by your advice I did go back to the first loop). I am trying to get some best practices that I can keep an eye out for. Something on the lines of "when you are done using a Collection, clear it out". I just really need to make sure not as much memory is being taken up by these applications.

• Sentiment analysis for twitter in python

  - by Ran

  I'm looking for an open source implementation, preferably in python, of Textual Sentiment Analysis (http://en.wikipedia.org/wiki/Sentiment_analysis). Is anyone familiar with such open source implementation I can use? I'm writing an application that searches twitter for some search term, say "youtube", and counts "happy" tweets vs. "sad" tweets. I'm using Google's appengine, so it's in python. I'd like to be able to classify the returned search results from twitter and I'd like to do that in python. I haven't been able to find such sentiment analyzer so far, specifically not in python. Are you familiar with such open source implementation I can use? Preferably this is already in python, but if not, hopefully I can translate it to python. Note, the texts I'm analyzing are VERY short, they are tweets. So ideally, this classifier is optimized for such short texts. BTW, twitter does support the ":)" and ":(" operators in search, which aim to do just this, but unfortunately, the classification provided by them isn't that great, so I figured I might give this a try myself. Thanks! BTW, an early demo is here and the code I have so far is here and I'd love to opensource it with any interested developer.

• NSURL Connection will/won't load data

  - by jkap

  So here's my issue: I followed the NSURLConnection tutorial in the iPhone Developer Documentation almost to the T, and it only kinda works. Here's where it all goes wrong: The object seems to be created correctly and delegates to connectionDidFinishLoading, but with any URL I try to load the response data always ends up only being 0 bytes. I am running in the simulator if that makes any difference. Here's my relevant code: - (void)viewDidLoad { [super viewDidLoad]; self.title = @"WVFS Player"; //create a request NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://wvfs.josh-kaplan.com/nowPlaying.php"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; // create a connection NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if(theConnection) { // create the datum responseData=[[NSMutableData data] retain]; } else { // code this later } } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [responseData setLength:0]; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { // make it work NSLog(@"Succeeded! Received %d bytes of data:",[responseData length]); // release it [connection release]; [responseData release]; } And here's my log output: [Session started at 2010-03-14 09:01:09 -0400.] 2010-03-14 09:01:14.784 WVFS[19571:207] Succeeded! Received 0 bytes of data: Any ideas? Thanks, Josh

• DDMS won't load (or doesn't parse?) KML file

  - by nderraugh

  I can't get DDMS to load any KML files. I have a KML file for example with the following in it: <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://www.opengis.net/kml/2.2"> <Placemark> <name>Simple placemark</name> <description>Attached to the ground. Intelligently places itself at the height of the underlying terrain.</description> <Point> <coordinates>-122.0822035425683,37.42228990140251,0</coordinates> </Point> </Placemark> </kml> The docs at http://developer.android.com/guide/developing/tools/ddms.html seem to indicate that I only need to launch my app and fire up DDMS and load the KML. That doesn't work. I even tried the Google Earth solution suggested at the same link. I'm using SDK 1.5_r2. I am doing something wrong or missing something?

• Android/Java -- Post simple text to Facebook wall?

  - by borg17of20

  Hello all, I'm trying to integrate posting to one's wall from within my app. I already have an area where the user can save his/her username and password (encrypted). I would like my program to recall the saved username and password, pass that to Facebook for authentication, and then allow the app to post simple text (maybe a link too) to the user's wall. That said, I've read everything on the developer pages at Facebook (the api looks completely foreign to me... I've never don't any type of web app development before... just desktop apps), and experimented with the Java libraries here: http://wiki.developers.facebook.com/index.php/User:Java but to be honest, I don't understand any of the various implementations. Some claim to be simple to use, but apparently they are all way above my head. I've even tried messing with the official Facebook Android SDK, but that uses a webview interface, and I can't pass in the username and password for easy authentication. Plus, I'm still clueless as to how to post to the wall even after correct authentication. Please help. Thanks. Oh, btw I already have a Facebook API key and Application ID.

• Bluetooth on 2.0+

  - by awiden

  I'm doing bluetooth development for connecting with a PC. I've basicly used the BTChatExample and changed the UUID to the standard PC SPP-profile. Trying to close a bluetooth application during a blocking read, by closing the BluetoothSocket will leave the Bluetooth stack in a unusable state. This can only be fixed by disabling and enabling bluetooth and restarting the application. Checking logcat, you can see that some of the internal methods are failing, leaving a open port. Any information on this? First of all there seams to be differences on how bluetooth is implemented on N1 and HTC Legend/Desire both running 2.1, do you know anything about this? Connecting isn't 100% reliable, sometimes I get a warning saying ~PortSystemContext init: FAILED. This leaves bluetooth unusable, and restarting is needed. Am I right in assuming that SPP is the only profile supported for use with the APIs? That's what the docs on the BluetoothAdapter says. I would love to discuss issues on bluetooth with a developer and iron out these bugs so that Android can have good proper BT support it deserves.

• Getting a gestureoverlayview

  - by Codejoy

  I have been using some nice tutorials on drawing graphics on my android. I wanted to also add in the cool gesture demo found here: http://developer.android.com/resources/articles/gestures.html That takes these lines of code: GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); This is fine and dandy yet I realize in my demo i'm trying to build using code from "Playing with Graphics in Android". The demos make sense, everything makes sense but I found out by using: setContentView(new Panel(this)); as is required by the Playing With Graphics tutorials, then the findViewById seems to no longer be valid and returns null. At first I was about to post a stupider question as to why this is happening, a quick test of playing with the setContentView made me realize the cause of findViewById returning null, I just do not know how to remedy this issue. Whats the key I am missing here? I realize that the new Panel is doinking some reference up but I am not sure how to make the connection here. THe: R.id.gestures is defined right int he main.xml as: (just like the tutorial) Thanks, Shane p.s. im new here be gentle.

• Useful training courses that aren't specific to a single technology

  - by Dave Turvey

  I have possibly the best problem in the world. I have about £1600 left in a training budget and I need to find something to spend it on. I can spend it on anything that could be considered training. Books, courses, conferences, etc. I would like to find a course that would benifit a software developer but is not about learning a specific programming technology. I don't really want to spend it on a technical training course. These topics are usually best learned with a good book and some trial and error. I have also already been on a general business/management training course and a PRINCE2 project management course. I am currently working on a project on my own so am responsible for communicating with the client, requirements gathering, project management, etc., as well as the coding. What training have you found useful outside the usual technical stuff? Has anyone done any business analysis courses? What were they like? Are there any courses on some of the practicalities of working with software, e.g. automated test and deployment strategies, handling technical support? I would prefer a course in the UK but I can travel if necessary.

• Why can't I send SOAP requests to Ebay finding API with this php?

• Nested instances in C#

  - by user32848

  I'm trying to translate some C++ code for a neural net into C#. I first took the C++ code, from a 1993 book, and ran it. Then translated it using the STL and it ran again. Now I'm trying to get it into C# with Visual Web Developer 2008 Express. The original code used "friend" classes and I'm just trying to do the same making everything "public". The following code compiles but only gives null references when run: public class ineuron { public Double weight, activation; public ineuron(Double set_wt) { weight = set_wt; } ... public class netwrk { public oneuron onrn; public ineuron in1, in2, in3, in4; public netwrk( Double inp_1, Double inp_2, Double inp_3, Double inp_4 ) { ineuron in1 = new ineuron(inp_1); ineuron in2 = new ineuron(inp_2); ... and later, in some code called by a button push: netwrk ntw = new netwrk(i_n1, i_n2, i_n3, i_n4); Unfortunately, trying to use: ntw.in1.activation etc. leads to null reference runtime errors. What am I forgetting to do? Barney

• Eclipse Plug-In Installation Issues

  - by Mudu

  Hi all I'm beginning to work with Eclipse for some Java development. I'm quite new to Eclipse, as I am a Visual Studio developer normally. I tried to install the CheckStyle Eclipse Plug-In and Subversive, using the Eclipse "Install new Software" feature. No errors, everything seems to have worked well. Clicking on "What software is already installed?" in the Install-dialogue shows me a list of installed plug-ins. Both Subversive and CheckStyle for Eclipse are listed. My only problem is that neither of them "work", that means I cannot see any new UI elements. According to the manual I have, I should see a new node "CheckStyle" in a project's properties. I haven't. I don't know exactly what Subversive looks like, but I'm sure there's a way to conveniently perform check-out operations etc. Manually copying the downloaded plug-in to the dropins-folder and restarting Eclipse subsequently does not help either. Is there a way to reliably find out whether there occurred any errors - I have no error message at all, what drives me crazy and makes the problem pretty difficult to describe/Google... Any help would be very cool! Cheers Matthias

• is struts2 Framework dead? if so, which direction to go from here?

  - by Omnipresent

  I've been working in struts2 framework for the past year and a half. As I look around SO it seems like struts2 questions get the least amount of hits. At first I thought it was because the SO community is not much into struts2, but this is the case in other forums as well. Only the struts2 mailing list is pretty active. I think struts2 is slowly becoming a dinosaur framework and I want to move on. I've dabbled a little with other stuff like RoR, Grails, Django, .NET MVC but I've never really committed and made a pact with myself to sit down and learn these. Maybe its the fact that I dont know the languages that these frameworks are built on. Spending a day or two with RoR makes me want to choke some of the JAR files and struts2 html tags and .NET MVC looks promising but not knowing c# ties me back. My question is, have you been on the same path? Did anyone used to do struts2 before and now changed to something new? What would you suggest I learn after Struts2? And lastly, as a developer how do you motivate yourself to learn a new framework, or a language? for me, just typing the code provided in the book is dead boring.

• Can a call to WaitHandle.SignalAndWait be ignored for performance profiling purposes?

  - by Dan Tao

  I just downloaded the trial version of ANTS Performance Profiler from Red Gate and am investigating some of my team's code. Immediately I notice that there's a particular section of code that ANTS is reporting as eating up to 99% CPU time. I am completely unfamiliar with ANTS or performance profiling in general (that is, aside from self-profiling using what I'm sure are extremely crude and frowned-upon methods such as double timeToComplete = (endTime - startTime).TotalSeconds), so I'm still fiddling around with the application and figuring out how it's used. But I did call the developer responsible for the code in question and his immediate reaction was "Yeah, that doesn't surprise me that it says that; but that code calls SignalAndWait [which I could see for myself, thanks to ANTS], which doesn't use any CPU, it just sits there waiting for something to do." He advised me to simply ignore that code and look for anything ELSE I could find. My question: is it true that SignalAndWait requires NO CPU overhead (and if so, how is this possible?), and is it reasonable that a performance profiler would view it as taking up 99% CPU time? I find this particularly curious because, if it's at 99%, that would suggest that our application is often idle, wouldn't it? And yet its performance has become rather sluggish lately. Like I said, I really am just a beginner when it comes to this tool, and I don't know anything about the WaitHandle class. So ANY information to help me to understand what's going on here would be appreciated.

• Visual Studio template not showing

  - by David

  Hi all I've followed this tutorial to try to add a template to Visual Studio: http://www.switchonthecode.com/tutorials/visual-studio-how-to-create-item-templates The template I have created is designed to add one predefined .aspx and one predefined .aspx.cs file to the project. The folder contains the following files: MoosePage.aspx MoosePage.aspx.cs MoosePage.vstemplate MoosePageItemTemplateIcon.ico The .vstemplate file looks like this: <VSTemplate Type="Item" Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005"> <TemplateData> <Name>MoosePage</Name> <Description>MoosePage Template</Description> <DefaultName>NewMoosePage</DefaultName> <ProjectType>CSharp</ProjectType> <Icon>MoosePageItemTemplateIcon.ico</Icon> </TemplateData> <TemplateContent> <ProjectItem TargetFileName="$fileinputname$.aspx" ReplaceParameters="true"> MoosePage.aspx </ProjectItem> <ProjectItem TargetFileName="$fileinputname$.aspx.cs" ReplaceParameters="true"> MoosePage.aspx.cs </ProjectItem> </TemplateContent> </VSTemplate> I have zipped the files up (.zip not .zipx) and placed the zip folder in My Documents\Visual Studio 2008\Templates\ItemTemplates\VisualWebDeveloper. I have restarted Visual Studio. When I go into my website project and choose Add New Item, I don't see my new template. Can anyone suggest what might have gone wrong? Thanks David

• Cocoa NSStream TCP connection to FTP

  - by Chuck

  Hi, I'm new to Cocoa, but not to programming. Recently I decided I wanted to write a FTP client for Mac, and so I first made it in the language I'm most comfortable in (on Windows), and then moved on to Cocoa when I had the workings of FTP communications down. My question is (apparently) a bit controversial: How do I establish a read/writeable connection to (a ftp server)? What I have so far (non working obviously): NSInputStream *iStream; NSOutputStream *oStream; NSHost *host = [NSHost hostWithAddress:@"127.0.0.1"]; [NSStream getStreamsToHost:host port:3333 inputStream:&iStream outputStream:&oStream]; // ftp port: 3333 [iStream retain]; [oStream retain]; [iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [oStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [iStream setDelegate:self]; [oStream setDelegate:self]; // which is not implemented apparently [iStream open]; [oStream open]; // .... [iStream write: (const uint8_t *)buf maxLength:8]; Which is partially based on http://developer.apple.com/mac/library/documentation/cocoa/Conceptual/Streams/Articles/NetworkStreams.html Now, why have I chosen NSStream? Because while this question is merely about how to connect to a FTP stream, my whole project will also include SSL and as far as I've been able to search here and on google, NSStream is capable of "switching" to a SSL connection. I've not been able to see the connection being made (which I'm usually able to do), but I also heard something about having to write to the stream before the stream will open? Any pointers are greatly appreciated, and sorry if my question is annoying - I'm new to Cocoa :)

• Assigning console.log to another object (Webkit issue)

  - by Trevor Burnham

  I wanted to keep my logging statements as short as possible while preventing console from being accessed when it doesn't exist; I came up with the following solution: var _ = {}; if (console) { _.log = console.debug; } else { _.log = function() { } } To me, this seems quite elegant, and it works great in Firefox 3.6 (including preserving the line numbers that make console.debug more useful than console.log). But it doesn't work in Safari 4. [Update: Or in Chrome. So the issue seems to be a difference between Firebug and the Webkit console.] If I follow the above with console.debug('A') _.log('B'); the first statement works fine in both browsers, but the second generates a "TypeError: Type Error" in Safari. Is this just a difference between how Firebug and the Safari Web Developer Tools implement console? If so, it is VERY annoying on Apple's Webkit's part. Binding the console function to a prototype and then instantiating, rather than binding it directly to the object, doesn't help. I could, of course, just call console.debug from an anonymous function assigned to _.log, but then I'd lose my line numbers. Any other ideas?

• oracle pl/sql bug: can't put_line more than 2000 characters

  - by FrustratedWithFormsDesigner

  Has anyone else noticed this phenomenon where dbms_output.put_line is unable to print more than 2000 characters at a time? Script is: set serveroutput on size 100000; declare big_str varchar2(2009); begin for i in 1..2009 loop big_str := big_str||'x'; end loop; dbms_output.put_line(length(big_str)); dbms_output.put_line(big_str); end; / I copied and pasted the output into an editor (Notepad++) which told me there were only 2000 characters, not 2009 which is what I think should have been pasted. This also happens with a few of my test scripts - only 2000 characters get printed. I have a workaround to print like this: dbms_output.put_line(length(big_str)); dbms_output.put_line(substr(big_str,1,1999)); dbms_output.put_line(substr(big_str,2000)); This adds new lines to the output, makes it hard to read when the text you're working with is preformatted. Has anyone else noticed this? Is it really a bug or some sort of obscure feature? Is there a better workaround? Is there any other information on this out there? Oracle version is: 10.2.0.3.0, using PL/SQL Developer (from Allround Automation).

  I worked on a fairly large project a while back where we modeled the classes in Enterprise Architect and generated the (partial) POCO classes (complete with model-driven business rule validations), persistence (NHibernate mapping file) and DDL. Based on certain model attributes we could flag alternate generation strategies or indicate that a particular portion would be entirely hand-coded. There was a good deal of initial investment, but it paid large dividends over the lifetime of a 15 developer, 3 year project. I'm investigating doing something similar with the current Microsoft technology stack. The place I'm stuck is that class modeling is done with the VS 2010 UML tools, but logical data modeling is done with Entity Data Modeler. Is it a reasonable path to use VS 2010 UML as the "single source of truth" and code generate the edmx files based on the class model? That's the inverse of the common path to create the entity model and use a POCO generator to generate classes. However, a good class model can be used to generate much more than just the properties so I tend to view it as a better choice than the entity model.

• Question about Multicast Delegates?

  - by IbrarMumtaz

  I am going through some exam questions for the 70-536 exam and an actual question one developer posted on his blog has popped up in my exam questions. I cannot remember what his answer was .... but below is the question: You need to write a multicast delegate that accepts a DateTime argument and returns a bool value. Which code segment should you use? A: public delegate int PowerDeviceOn(bool, DateTime) B: public delegate bool PowerDeviceOn(Object, EventArgs) C: public delegate void PowerDeviceOn(DateTime) D: public delegate bool PowerDeviceOn(DateTime) The answer is A. Can someone please explain why? As I already did some research into this question a while ago and so I was sure that it was C, obviously now looking back at the question its clear that I did not read properly. As i was sure I had seen the same one before so I jumped to the most obvious one. A variation on this question: You need to write a multicast delegate that accepts a DateTime argument. Which code segment should you use? A: public delegate int PowerDeviceOn(bool, DateTime) B: public delegate bool PowerDeviceOn(Object, EventArgs) C: public delegate void PowerDeviceOn(DateTime) D: public delegate bool PowerDeviceOn(DateTime) Now this is another variation on this question, it still has the same bogus sample answers, as they still kind work in throwing the exam taker off. Notice how by simply keeping the sample answers the same and by removing a small portion of the question text, the answer is C and not A. The variation has no official answer as I just conjured it up using the exam question as a baseplate. The answer is definitely C. This time round its easy to see why C is correct but the very first question I have an inkling but as you know an inkling is not good enough in passing exams. Thanks For Reading.
