  • Can Spring.Net function as PostSharp?

    - by Alex K
    A few months back I've discovered PostSharp, and for a time, it was good. But then legal came back with an answer saying that they don't like the licence of the old versions. Then the department told me that 2.0's price was unacceptably high (for the number of seats we need)... I was extremely disapponted, but not disheartened. Can't be the only such framework, I thought. I kept looking for a replacement, but most of it was either dead, ill maintained (especially in documentation department), for academic use, or all of the above (I'm looking at you Aspect.Net) Then I've discovered Spring.Net, and for a time, it was good. I've been reading the documentation and it went on to paint what seemed to be a supperior picture of an AOP nirvana. No longer was I locked to attributes to mark where I wanted code interception to take place, but it could be configured in XML and changes to it didn't require re-compile. Great. Then I looked at the samples and saw the following, in every single usage scenario: // Create AOP proxy using Spring.NET IoC container. IApplicationContext ctx = ContextRegistry.GetContext(); ICommand command = (ICommand)ctx["myServiceCommand"]; command.Execute(); if (command.IsUndoCapable) { command.UnExecute(); } Why must the first two lines of code exist? It ruins everything. This means I cannot simply provide a user with a set of aspects and attributes or XML configs that they can use by sticking appropriate attributes on the appropriate methods/classes/etc or editing the match pattern in XML. They have to modify their program logic to make this work! Is there a way to make Spring.Net behave as PostSharp in this case? (i.e. user only needs to add attributes/XML config, not edit content of any methods. Alternatively, is there a worthy and functioning alternative to PostSharp? I've seen a few question titled like this on SO, but none of them were actually looking to replace PostSharp, they only wanted to supplement its functionality. I need full replacement.

  • Best programming aids for a quadriplegic programmer

    - by Peter Rowell
    Before you jump to conclusions, yes, this is programming related. It covers a situation that comes under the heading of, "There, but for the grace of God, go you or I." This is brand new territory for me so I'm asking for some serious help here. A young man, Honza Ripa, in a nearby town did the classic Dumb Thing two weeks after graduating from High School -- he dove into shallow water in the Russian River and had a C-4/C-5 break, sometimes called a Swimming Pool break. In a matter of seconds he went from an exceptional golfer and wrestler to a quadriplegic. (Read the story ... all of us should have been so lucky as to have a girlfriend like Brianna.) That was 10 months ago and he has regained only tiny amounts of control of his right index finger and a couple of other hand/foot motions, none of them fine-grained. His total control of his computer (currently running Win7, but we can change that as needed) is via voice command. Honza's not dumb. He had a 3.7 GPA with AP math and physics. The Problems: Since all of his input is via voice command, he is concerned that the predominance of special characters in programming will require vast amount of verbose commands. Does anyone know of any well done voice input system specifically designed for programmers? I'm thinking about something that might be modal--e.g. you say "Python input" and it goes into a macro mode for doing class definitions, etc. Given all of the RSI in programmer-land there's got to be something out there. What OS(es) does it run on? I am planning on teaching him Python, which is my preferred language for programming and teaching. Are there any applications / whatevers that are written in Python and would be a particularly good match for engaging him mentally while supporting his disability? One of his expressed interests is in stock investing, but that not might be a good starting point for a brand-new programmer. There are a lot of environments (Flash, JavaScript, etc) that are not particularly friendly to people with accessibility challenges. I vaguely remember (but cannot find) a research project that basically created an overlay system on top of a screen environment and then allowed macro command construction on top of the screen image. If we can get/train this system, we may be able to remove many hurdles to using the net. I am particularly interested in finding open source Python-based robotics and robotic prostheses projects so that he can simultaneously learn advanced programming concepts while learning to solve some of his own immediate problems. I've done a ton of googling on this, but I know there things I'm missing. I'm asking the SO community to step up to the plate here. I know this group has the answers, so let me hear them! Overwhelm me with the opportunities that any of us might have/need to still program after such a life-changing event.

  • Single Sign On for a Web App

    - by Jeremy Goodell
    I have been trying to understand how this problem is solved for over a month now. I really need to come up with a general approach that works -- I'm basically the only resource who can do it. I have a theory, but I'm just not sure it's the easiest (or correct) approach and I haven't been able to find any information to support my ideas. Here's the scenario: 1) You have a complex web application that offers secure content on a subscription basis. 2) Users are required to log in to your application with user name and password. 3) You sell to large corporations, which already have a corporate authentication technology (for example, Active Directory). 4) You would like to integrate with the corporate authentication mechanism to allow their users to log onto your Web App without having to enter their user name and password. Now, any solution you come up with will have to provide a mechanism for: adding new users removing users changing user information allowing users to log in Ideally, all these would happen "automagically" when the corporate customer made the corresponding changes to their own authentication. Now, I have a theory that the way to do this (at least for Active Directory) would be for me to write a client-side app that integrates with the customer's Active Directory to track the targeted changes, and then communicate those changes to my Web App. I think that if this communication were done via Web Services offered by my web app, then it would maintain an unhackable level of security, which would obviously be a requirement for these corporate customers. I've found some information about a Microsoft product called Active Directory Federation Service (ADFS) which may or may not be the right approach for me. It seems to be a bit bulky and have some requirements that might not work for all customers. For other existing ID scenarios (like Athens and Shibboleth), I don't think a client application is necessary. It's probably just a matter of tying into the existing ID services. I would appreciate any advice anyone has on anything I've mentioned here. In particular, if you can tell me if my theory is correct about providing a client-side app that communicates with server-side Web Services, or if I'm totally going in the wrong direction. Also, if you could point me at any web sites or articles that explain how to do this, I'd really appreciate it. My research has not turned up much so far. Finally, if you could let me know of any Web applications that currently offer this service (particularly as tied to a corporate Active Directory), I would be very grateful. I am wondering if other B2B Web app's like salesforce.com, or hoovers.com offer a similar service for their corporate customers. I hate being in the dark and would greatly appreciate any light you can shed ... Jeremy

  • javax.servlet.ServletException - how could i get to the cause?

    - by Michal
    Hi, i'm getting a very strange error while opening one of the pages in my web app. The application is built on Seam 2.2 and is using JSF (RichFaces) as a view technology. I run it on Tomcat 6. The error i'm describing doesn't occur on my machine (Mac OS X), but it does on my client's dev machines (Windows) and on the server (Linux Debian). I'm sure i'm running the same version on each system and i have tried connecting to the same database... In logs everything looks fine - each next JSF Phase executes normally, and after the last one, there is this moment when the request starts processing for the SEAM debug page... And this is the stack trace i see on the debug page (nothing is logged): Exception during request processing: Caused by javax.servlet.ServletException with message: "Servlet execution threw an exception" org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:313) org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:83) org.jboss.seam.web.IdentityFilter.doFilter(IdentityFilter.java:40) org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) org.jboss.seam.web.MultipartFilter.doFilter(MultipartFilter.java:90) org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:64) org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:45) org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:178) org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:290) org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:388) org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:515) org.jboss.seam.web.Ajax4jsfFilter.doFilter(Ajax4jsfFilter.java:56) org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) org.jboss.seam.web.LoggingFilter.doFilter(LoggingFilter.java:60) org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) org.jboss.seam.web.HotDeployFilter.doFilter(HotDeployFilter.java:53) org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:158) org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) pl.mgibowski.alterium.util.LoggingFilter.doFilter(LoggingFilter.java:18) org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:465) org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) java.lang.Thread.run(Thread.java:619) Exception without any cause... I was trying to catch the exception with my custom Filter (LoggingFilter.java that you can see on the strack trace), using this code: try { filterChain.doFilter(servletRequest, servletResponse); } catch (Throwable e) { e.printStackTrace(); System.out.println("Stack trace:"); System.out.println(e.getStackTrace()); System.out.println("Cause:"); System.out.println(e.getCause()); } But it doesn't catch anything, the line 18 from the stack trace is this one: filterChain.doFilter(servletRequest, servletResponse); nothing gets caught by the try block. Anybody has any ideas about how could i get closer to the real cause?

  • Why is code quality not popular?

    - by Peter Kofler
    I like my code being in order, i.e. properly formatted, readable, designed, tested, checked for bugs, etc. In fact I am fanatic about it. (Maybe even more than fanatic...) But in my experience actions helping code quality are hardly implemented. (By code quality I mean the quality of the code you produce day to day. The whole topic of software quality with development processes and such is much broader and not the scope of this question.) Code quality does not seem popular. Some examples from my experience include Probably every Java developer knows JUnit, almost all languages implement xUnit frameworks, but in all companies I know, only very few proper unit tests existed (if at all). I know that it's not always possible to write unit tests due to technical limitations or pressing deadlines, but in the cases I saw, unit testing would have been an option. If a developer wanted to write some tests for his/her new code, he/she could do so. My conclusion is that developers do not want to write tests. Static code analysis is often played around in small projects, but not really used to enforce coding conventions or find possible errors in enterprise projects. Usually even compiler warnings like potential null pointer access are ignored. Conference speakers and magazines would talk a lot about EJB3.1, OSGI, Cloud and other new technologies, but hardly about new testing technologies or tools, new static code analysis approaches (e.g. SAT solving), development processes helping to maintain higher quality, how some nasty beast of legacy code was brought under test, ... (I did not attend many conferences and it propably looks different for conferences on agile topics, as unit testing and CI and such has a higer value there.) So why is code quality so unpopular/considered boring? EDIT: Thank your for your answers. Most of them concern unit testing (and has been discussed in a related question). But there are lots of other things that can be used to keep code quality high (see related question). Even if you are not able to use unit tests, you could use a daily build, add some static code analysis to your IDE or development process, try pair programming or enforce reviews of critical code.

  • Salesforce/PHP - Bulk Outbound message (SOAP), Time out issue

    - by Phill Pafford
    Salesforce can send up to 100 requests inside 1 SOAP message. While sending this type of Bulk Ooutbound message request my PHP script finishes executing but SF fails to accept the ACK used to clear the message queue on the Salesforce side of things. Looking at the Outbound message log (monitoring) I see all the messages in a pending state with the Delivery Failure Reason "java.net.SocketTimeoutException: Read timed out". If my script has finished execution, why do I get this error? I have tried these methods to increase the execution time on my server as I have no access on the Salesforce side: set_time_limit(0); // in the script max_execution_time = 360 ; Maximum execution time of each script, in seconds max_input_time = 360 ; Maximum amount of time each script may spend parsing request data memory_limit = 32M ; Maximum amount of memory a script may consume I used the high settings just for testing. Any thoughts as to why this is failing the ACK delivery back to Salesforce? Here is some of the code: This is how I accept and send the ACK file for the imcoming SOAP request $data = 'php://input'; $content = file_get_contents($data); if($content) { respond('true'); } else { respond('false'); } The respond function function respond($tf) { $ACK = <<<ACK <?xml version = "1.0" encoding = "utf-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <notifications xmlns="http://soap.sforce.com/2005/09/outbound"> <Ack>$tf</Ack> </notifications> </soapenv:Body> </soapenv:Envelope> ACK; print trim($ACK); } These are in a generic script that I include into the script that uses the data for a specific workflow. I can process about 25 requests (That are in 1 SOAP response) but once I go over that I get the timeout error in the Salesforce queue. for 50 requests is usually takes my PHP script 86.77 seconds. Could it be Apache? PHP? I have also tested just accepting the 100 request SOAP response and just accepting and sending the ACK the queue clears out, so I know it's on my side of things. I show no errors in the apache log, the script runs fine. Thanks for any insight into this, --Phill

    This project in Vs2008 targeting .net 3.5 used to compile views.

The compile is a success but it does not catch the view compilation errors. I have Vs2010 ultimate, vs 2008 developer+database edition on this machine. So either it compiles ignoring the errors with some combinations of the fixes I've tried, or it errors with Error 410 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.

  • Why not .NET-style delegates rather than closures in Java?

    - by h2g2java
    OK, this is going to be my beating a dying horse for the 3rd time. However, this question is different from my earlier two about closures/delegates, which asks about plans for delegates and what are the projected specs and implementation for closures. This question is about - why is the Java community struggling to define 3 different types of closures when we could simply steal the whole concept of delegates lock, stock and barrel from our beloved and friendly neighbour - Microsoft. There are two non-technical conclusions I would be very tempted to jump into: The Java community should hold up its pride, at the cost of needing to go thro convoluted efforts, by not succumbing to borrowing any Microsoft concepts or otherwise vindicate Microsoft's brilliance. Delegates is a Microsoft patented technology. Alright, besides the above two possibilities, Q1. Is there any weakness or inadequacy in msft-styled delegates that the three (or more) forms of closures would be addressing? Q2. I am asking this while shifting between java and c# and it intrigues me that c# delegates does exactly what I needed. Are there features that would be implemented in closures that are not currently available in C# delegates? If so what are they because I cannot see what I need more than what C# delegates has adequately provided me? Q3. I know that one of the concerns about implementing closures/delegates in java is the reduction of orthogonality of the language, where more than one way is exposed to perform a particular task. Is it worth the level convolution and time spent to avoid delegates just to ensure java retains its level of orthogonality? In SQL, we know that it is advisable to break orthogonality by frequently adequately satisfying only the 2nd normal form. Why can't java be subjected to reduction of orthogonality and OO-ness for the sake of simplicity? Q4. The architecture of JVM is technically constrained from implementing .NET-styled delegates. If this reason WERE (subjunctive to emphasize unlikelihood) true, then why can't the three closures proposals be hidden behind a simple delegate keyword or annotation: if we don't like to use @delegate, we could use @method. I cannot see how delegate statement format is more complex than the three closure proposals.

  • Union struct produces garbage and general question about struct nomenclature

    - by SoulBeaver
    I read about unions the other day( today ) and tried the sample functions that came with them. Easy enough, but the result was clear and utter garbage. The first example is: union Test { int Int; struct { char byte1; char byte2; char byte3; char byte4; } Bytes; }; where an int is assumed to have 32 bits. After I set a value Test t; t.Int = 7; and then cout cout << t.Bytes.byte1 << etc... the individual bytes, there is nothing displayed, but my computer beeps. Which is fairly odd I guess. The second example gave me even worse results. union SwitchEndian { unsigned short word; struct { unsigned char hi; unsigned char lo; } data; } Switcher; Looks a little wonky in my opinion. Anyway, from the description it says, this should automatically store the result in a high/little endian format when I set the value like Switcher.word = 7656; and calling with cout << Switcher.data.hi << endl The result of this were symbols not even defined in the ASCII chart. Not sure why those are showing up. Finally, I had an error when I tried correcting the example by, instead of placing Bytes at the end of the struct, positioning it right next to it. So instead of struct {} Bytes; I wanted to write struct Bytes {}; This tossed me a big ol' error. What's the difference between these? Since C++ cannot have unnamed structs it seemed, at the time, pretty obvious that the Bytes positioned at the beginning and at the end are the things that name it. Except no, that's not the entire answer I guess. What is it then?

  • How much abstraction is too much?

    - by Daniel Bingham
    In an Object Oriented Program: How much abstraction is too much? How much is just right? I have always been a nuts and bolts kind of guy. I understood the concept behind high levels of encapsulation and abstraction, but always felt instinctively that adding too much would just confuse the program. I always tried to shoot for an amount of abstraction that left no empty classes or layers. And where in doubt, instead of adding a new layer to the hierarchy, I would try and fit something into the existing layers. However, recently I've been encountering more highly abstracted systems. Systems where everything that could require a representation later in the hierarchy gets one up front. This leads to a lot of empty layers, which at first seems like bad design. However, on second thought I've come to realize that leaving those empty layers gives you more places to hook into in the future with out much refactoring. It leaves you greater ability to add new functionality on top of the old with out doing nearly as much work to adjust the old. The two risks of this seem to be that you could get the layers you need wrong. In this case one would wind up still needing to do substantial refactoring to extend the code and would still have a ton of never used layers. But depending on how much time you spend coming up with the initial abstractions, the chance of screwing it up, and the time that could be saved later if you get it right - it may still be worth it to try. The other risk I can think of is the risk of over doing it and never needing all the extra layers. But is that really so bad? Are extra class layers really so expensive that it is much of a loss if they are never used? The biggest expense and loss here would be time that is lost up front coming up with the layers. But much of that time still might be saved later when one can work with the abstracted code rather than more low level code. So when is it too much? At what point do the empty layers and extra "might need" abstractions become overkill? How little is too little? Where's the sweet spot? Are there any dependable rules of thumb you've found in the course of your career that help you judge the amount of abstraction needed?

  • An existing connection was forcibly closed by the remote host

    - by George
    I have a fat VB.NET Winform client that is using the an old asmx style web service. Very often, when I perform query that takes a while, I get the subject error. The error happenes The error seems to occur in < 1 min, which is far less that the web service timeout value that I have set or the timeout value on the ADO Command object that is performing the query within the web server. It seems to occur whenever I am performing a large query that expects to return a lot of rows or when I am sending up a large amount of data to the web service. For example, it just occurred when I was passing a large dataset to the web server: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at Smit.Pipeline.Bo.localhost.WsSR.SaveOptions(String emailId, DataSet dsNeighborhood, DataSet dsOption, DataSet dsTaskApplications, DataSet dsCcUsers, DataSet dsDistinctUsers, DataSet dsReferencedApplications) in C:\My\Code\Pipeline2\Smit.Pipeline.Bo\Web References\localhost\Reference.vb:line 944 at Smit.Pipeline.Bo.Options.Save(TaskApplications updatedTaskApplications) in I've been looking a tons of postings on this error and it is surprising at how varied the circumstances which cause this error are. I've tried messing with Wireshark, but I am clueless how to use it. This application only has about 20 users at any one time and I am able to reproduce this error in the middle of the night when probably no one is using the app, so I don't think that the number of requests to the web server or to the database is high. It's probably one right now when I just got the error now. It seems to have to do everything with the amt of data being passed in either direction. This error is really chronic and killing me. Please help.

  • JQuery Tooltip Plugin from Jorn

    - by Jeff Ancel
    I am thinking someone may have run across this one, but not sure. From a high level, I am trying to roll over a input [type=text] and display a tool tip (with the contained value) using the plugin available at http://bassitance.de. I have to use titles and classes for validation on the specific elements, so I put a blank div to hold the input [type=text] value for the roll over. Issue: It won't hold the value of 2 text boxes at once. Once I put a value in the box on the right, the tooltip on the left goes away. Same thing if I switch it aroun. I can't keep a tooltip on more than one element. Here is the code (Note: You will have to download the plugins in the source as I am not sure where the live versions are if there are any). <link rel="stylesheet" href="/scripts/jquery-tooltip/jquery.tooltip.css" /> <script type="text/javascript" src="/scripts/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="/scripts/jquery-tooltip/jquery.tooltip.min.js"></script> <script type="text/javascript"> $(function(){ $("input").change(function(){ var newTitle = $(this).val(); $(this).parent().attr("title",newTitle); // re-init tool tip reload(); }); // Init tooltip reload(); }); reload = function(){ $("div").tooltip(); } </script> <body> <table border="1px solid black"> <tr> <td title="hello"> <div> <input type="text" value=""/> </div> </td> <td> <div> <input type="text" value=""/> </div> </td> </tr> </table> <div id="debug"></div> </body> </html>

  • Strategy pattern and "action" classes explosion

    - by devoured elysium
    Is it bad policy to have lots of "work" classes(such as Strategy classes), that only do one thing? Let's assume I want to make a Monster class. Instead of just defining everything I want about the monster in one class, I will try to identify what are its main features, so I can define them in interfaces. That will allow to: Seal the class if I want. Later, other users can just create a new class and still have polymorphism by means of the interfaces I've defined. I don't have to worry how people (or myself) might want to change/add features to the base class in the future. All classes inherit from Object and they implement inheritance through interfaces, not from mother classes. Reuse the strategies I'm using with this monster for other members of my game world. Con: This model is rigid. Sometimes we would like to define something that is not easily achieved by just trying to put together this "building blocks". public class AlienMonster : IWalk, IRun, ISwim, IGrowl { IWalkStrategy _walkStrategy; IRunStrategy _runStrategy; ISwimStrategy _swimStrategy; IGrowlStrategy _growlStrategy; public Monster() { _walkStrategy = new FourFootWalkStrategy(); ...etc } public void Walk() { _walkStrategy.Walk(); } ...etc } My idea would be next to make a series of different Strategies that could be used by different monsters. On the other side, some of them could also be used for totally different purposes (i.e., I could have a tank that also "swims"). The only problem I see with this approach is that it could lead to a explosion of pure "method" classes, i.e., Strategy classes that have as only purpose make this or that other action. In the other hand, this kind of "modularity" would allow for high reuse of stratagies, sometimes even in totally different contexts. What is your opinion on this matter? Is this a valid reasoning? Is this over-engineering? Also, assuming we'd make the proper adjustments to the example I gave above, would it be better to define IWalk as: interface IWalk { void Walk(); } or interface IWalk { IWalkStrategy WalkStrategy { get; set; } //or something that ressembles this } being that doing this I wouldn't need to define the methods on Monster itself, I'd just have public getters for IWalkStrategy (this seems to go against the idea that you should encapsulate everything as much as you can!) Why? Thanks

  • C# Confusing Results from Performance Test

    - by aip.cd.aish
    I am currently working on an image processing application. The application captures images from a webcam and then does some processing on it. The app needs to be real time responsive (ideally < 50ms to process each request). I have been doing some timing tests on the code I have and I found something very interesting (see below). clearLog(); log("Log cleared"); camera.QueryFrame(); camera.QueryFrame(); log("Camera buffer cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); Each time the log is called the time since the beginning of the processing is displayed. Here is my log output: [3 ms]Log cleared [41 ms]Camera buffer cleared [41 ms]Sx: 589 Sy: 414 [112 ms]Camera output acuired for processing The timings are computed using a StopWatch from System.Diagonostics. QUESTION 1 I find this slightly interesting, since when the same method is called twice it executes in ~40ms and when it is called once the next time it took longer (~70ms). Assigning the value can't really be taking that long right? QUESTION 2 Also the timing for each step recorded above varies from time to time. The values for some steps are sometimes as low as 0ms and sometimes as high as 100ms. Though most of the numbers seem to be relatively consistent. I guess this may be because the CPU was used by some other process in the mean time? (If this is for some other reason, please let me know) Is there some way to ensure that when this function runs, it gets the highest priority? So that the speed test results will be consistently low (in terms of time). EDIT I change the code to remove the two blank query frames from above, so the code is now: clearLog(); log("Log cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); The timing results are now: [2 ms]Log cleared [3 ms]Sx: 589 Sy: 414 [5 ms]Camera output acuired for processing The next steps now take longer (sometimes, the next step jumps to after 20-30ms, while the next step was previously almost instantaneous). I am guessing this is due to the CPU scheduling. Is there someway I can ensure the CPU does not get scheduled to do something else while it is running through this code?

  • Classic ASP vs. ASP.NET encryption options

    - by harrije
    I'm working on a web site where the new pages are ASP.NET and the legacy pages are Classic ASP. Being new to development in the Windows env, I've been studying the latest technology, i.e. .NET and I become like a deer in headlights when ever legacy issues come up regarding COM objects. Security on the website is an abomination, but I've easily encrypted the connectionStrings in the web.config file per http://www.4guysfromrolla.com/articles/021506-1.aspx based on DPAPI machine mode. I understand this approach is not the most secure, but it's better than nothing which is what it was for the ASP.NET pages. Now, I question how to do similar encryption for the connection strings used by the Classic ASP pages. A complicating factor is that the web sited is hosted where I do not have admin permissions or even command line access, just FTP. Moreover I want to avoid managing the key. My research has found: DPAPI with COM interop. Seems like this should already be available, but the only thing I could find discussing this is CyptoUtility (see http://msdn.microsoft.com/en-us/magazine/cc163884.aspx) which is not installed on the hosting server. There are plenty of other third party COM objects, e.g. Crypto from Dalun Software http://www.dalun.com, but these aren't on the hosted server either, and they look to me to require you to do some kind of key management. There is CAPICOM on the hosted server, but M$ has deprecated it and many report it is not the easiest to use. It is not clear to me whether I can avoid key management with CAPICOM similar to using DPAPI for ASP.NET. If anyone happens to know, please clue me in. I could write an web service in ASP.NET and have the classic ASP pages use it to get the decrypted connection strings and then store those in an application variable. I would not need to use SSL since I could use localhost and nothing would be sent over the internet. In the simpliest form I could implement what someone termed a poor man's version based on a simple XML stream, however, I really was looking to avoid any development since I find it hard to believe there is not a simple solution for Classic ASP like there is for ASP.NET. Maybe I'm missing some options... Recommendations are requested...

  • AutoScaleMode problems with changed default font

    - by Doc Brown
    Hi, I have some problems with the Form.AutoScaleMode property together with fixed size controls, when using a non-default font. I boiled it down to a simple test application (WinForms 2.0) with only one form, some fixed size controls and the following properties: class Form1 : Form { // ... private void InitializeComponent() { // ... this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi; this.Font = new System.Drawing.Font("Tahoma", 9.25F); // ... } } Under 96dpi, Windows XP, the form looks correctly like this 96 dpi example. Under 120 dpi, Windows XP, the the Windows Forms autoscaling feature produces this 120 dpi example. As you can see, groupboxes, buttons, list or tree views are scaled correctly, multiline text boxes get too big in the vertical axis, and a fixed size label does not scale correctly in both vertical and horizontal direction. Seems to be bug in the .NET framework? Using the default font (Microsoft Sans Serif 8.25pt), this problem does not occur. Using AutoScaleMode=Font (with adequate AutoScaleDimensions, of course) either does not scale at all or scales exactly like seen above, depending on when the Font is set (before or after the change of AutoScaleMode). The problem is not specific to the "Tahoma" Font, it occurs also with Microsoft Sans Serif, 9.25pt. And yes, i already read this SO post http://stackoverflow.com/questions/2114857/high-dpi-problems but it does not really help me. Any suggestions how to come around this? EDIT: I changed my image hoster, hope this one works better. EDIT2: Some additional information about my intention: I have about 50 already working fixed size dialogs with several hundreds of properly placed, fixed size controls. They were migrated from an older C++ GUI framework to C#/Winforms, that's why they are all fixed-size. All of them look fine with 96 dpi using a 9.25pt font. Under the old framework, scaling to 120 dpi worked fine - all fixed size controls scaled equal in both dimensions. Last week, we detected this strange scaling behaviour under WinForms when switching to 120 dpi. You can imagine that most of our dialogs now look very bad under 120 dpi. We are looking for a solution that avoids a complete redesign all those dialogs.

  • NSXMLParser Memory Allocation Efficiency for the iPhone

    - by Staros
    Hello, I've recently been playing with code for an iPhone app to parse XML. Sticking to Cocoa, I decided to go with the NSXMLParser class. The app will be responsible for parsing 10,000+ "computers", all which contain 6 other strings of information. For my test, I've verified that the XML is around 900k-1MB in size. My data model is to keep each computer in an NSDictionary hashed by a unique identifier. Each computer is also represented by a NSDictionary with the information. So at the end of the day, I end up with a NSDictionary containing 10k other NSDictionaries. The problem I'm running into isn't about leaking memory or efficient data structure storage. When my parser is done, the total amount of allocated objects only does go up by about 1MB. The problem is that while the NSXMLParser is running, my object allocation is jumping up as much as 13MB. I could understand 2 (one for the object I'm creating and one for the raw NSData) plus a little room to work, but 13 seems a bit high. I can't imaging that NSXMLParser is that inefficient. Thoughts? Code... The code to start parsing... NSXMLParser *parser = [[NSXMLParser alloc] initWithData: data]; [parser setDelegate:dictParser]; [parser parse]; output = [[dictParser returnDictionary] retain]; [parser release]; [dictParser release]; And the parser's delegate code... -(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { if(mutableString) { [mutableString release]; mutableString = nil; } mutableString = [[NSMutableString alloc] init]; } -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(self.mutableString) { [self.mutableString appendString:string]; } } -(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if([elementName isEqualToString:@"size"]){ //The initial key, tells me how many computers returnDictionary = [[NSMutableDictionary alloc] initWithCapacity:[mutableString intValue]]; } if([elementName isEqualToString:hashBy]){ //The unique identifier if(mutableDictionary){ [mutableDictionary release]; mutableDictionary = nil; } mutableDictionary = [[NSMutableDictionary alloc] initWithCapacity:6]; [returnDictionary setObject:[NSDictionary dictionaryWithDictionary:mutableDictionary] forKey:[NSMutableString stringWithString:mutableString]]; } if([fields containsObject:elementName]){ //Any of the elements from a single computer that I am looking for [mutableDictionary setObject:mutableString forKey:elementName]; } } Everything initialized and released correctly. Again, I'm not getting errors or leaking. Just inefficient. Thanks for any thoughts!

  • Contract developer trying to get outsourcing contract with current client.

    - by Mike
    I work for a major bank as a contract software developer. I've been there a few months, and without exception this place has the worst software practices I've ever seen. The software my team makes has no formal testing, terrible code (not reusable, hard to read, etc), minimal documentation, no defined development process and an absolutely sickening amount of waste due to bureaucratic overhead. Part of my contract is to maintain a group of thousands of very poorly written batch jobs. When one of the jobs fails (read: crashes), it's a developers job to look at the source, figure out what's wrong, fix it, and check it in. There is no quality assurance process or auditing of the results whatsoever. Once the developer says "it works" a manager signs off and it goes into production. What's disturbing is that these jobs essentially grab market data and put it into a third-party risk management system, which provides the bank with critical intelligence. I've discovered the disturbing truth that this has been happening since the 90s and nobody really has evidence the system is getting the correct data! Without going into details, an issue arose on Friday that was so horrible I actually stormed out of the place. I was ready to quit, but I decided to just get out to calm my nerves and possibly go back Monday. I've been reflecting today on how to handle this. I have realized that, in probably less than 6 months, I could (with 2 other developers) remake a large component of this system. The new system would provide them with, as primary benefits, a maintainable codebase less prone to error and a solid QA framework. To do it properly I would have to be outside the bank, the internal bureaucracy is just too much. And moreover, I think a bank is fundamentally not a place that can make good software. This is my plan. Write a report explaining in depth all the problems with their current system Explain why their software practices fail and generate a tremendous amount of error and waste. Use this as the basis for claiming the project must be developed externally. Write a high level development plan, including what resources I will require Hand 1,2,3 to my manager, hopefully he passes it up the chain. Worst case he fires me, but this isn't so bad. Convinced Executive decides to award my company a contract for the new system I have 8 years experience as a software contractor and have delivered my share of successful software products, but all working in-house for small/medium sized companies. When I read this over, I think I have a dynamite plan. But since this is the first time doing something this bold so I have my doubts. My question is, is this a good idea? If you think not, please spare no detail.

  • Is this asking too much of a browser?

    - by Matt Ball
    I'm embedding a large array in <script> tags in my HTML, like this (nothing surprising): <script> var largeArray = [/* lots of stuff in here */]; </script> In this particular example, the array has 210,000 elements. That's well below the theoretical maximum of 231 - by 4 orders of magnitude. Here's the fun part: if I save JS source for the array to a file, that file is 44 megabytes (46,573,399 bytes, to be exact). If you want to see for yourself, you can download it from my Dropbox. (All the data in there is canned, so much of it is repeated. This will not be the case in production.) Now, I'm really not concerned about serving that much data. My server gzips its responses, so it really doesn't take all that long to get the data over the wire. However, there is a really nasty tendency for the page, once loaded, to crash the browser. I'm not testing at all in IE (this is an internal tool). My primary targets are Chrome 8 and Firefox 3.6. In Firefox, I can see a reasonably useful error in the console: Error: script stack space quota is exhausted In Chrome, I simply get the sad-tab page: Cut to the chase, already Is this really too much data for our modern, "high-performance" browsers to handle? Is there anything I can do* to gracefully handle this much data? Incidentally, I was able to get this to work (read: not crash the tab) on-and-off in Chrome. I really thought that Chrome, at least, was made of tougher stuff, but apparently I was wrong... Edit 1 @Crayon: I wasn't looking to justify why I'd like to dump this much data into the browser at once. Short version: either I solve this one (admittedly not-that-easy) problem, or I have to solve a whole slew of other problems. I'm opting for the simpler approach for now. @various: right now, I'm not especially looking for ways to actually reduce the number of elements in the array. I know I could implement Ajax paging or what-have-you, but that introduces its own set of problems for me in other regards. @Phrogz: each element looks something like this: {dateTime:new Date(1296176400000), terminalId:'terminal999', 'General___BuildVersion':'10.05a_V110119_Beta', 'SSM___ExtId':26680, 'MD_CDMA_NETLOADER_NO_BCAST___Valid':'false', 'MD_CDMA_NETLOADER_NO_BCAST___PngAttempt':0} @Will: but I have a computer with a 4-core processor, 6 gigabytes of RAM, over half a terabyte of disk space ...and I'm not even asking for the browser to do this quickly - I'm just asking for it to work at all! ? *other than the obvious: sending less data to the browser

  • Mixing application modules between Silverlight and ASP.NET

    - by jkohlhepp
    Background: I work in a suite of ASP.NET applications that have several different "modules". The applications all share a main menu, so they all link to one-another. The modules are the high-level areas of the application. So, for example, it might be Payments, Orders, Customers, Products, etc. And Payments and Orders are in one app and Products and Customers are in another. Some of these menu links are "deep links", for example it might be a link to a particular page within the Customers module, such as Create New Customer. The issue: We are about to start a project that will add several more modules to this suite, probably as a new .NET application. I'm thinking about doing these new modules in Silverlight (for various reasons that are not material to the question). If I were to do that, I need to make the menu look the same as the menu in ASP.NET, as the users still need to feel like they are inside one "application". My questions: How should I organize the Silverlight project(s) so that I can "deep link" from ASP.NET pages into particular modules in the Silverlight app? What is even the best idea for creating these different Silverlight "modules"? If I had something that would've been a page in ASP.NET (for example - Create Customer), should each one of those be a separate Silverlight app? Or should it be a separate User Control? Or something else? Should I reuse our shared ASP.NET menu, and deep link to different Silverlight "modules" even within the new application? Or should I reimplement the menu in Silverlight for navigation within the app? Are there menu controls for Silverlight that look similar to ASP.NET menus (with flyout submenus in this case)? Could I maybe even share a SiteMap XML file between them? Edit: After looking around a bit more, it seems like PRISM might be the answer for some of my issues. It would allow me to modularize the different chunks of Silverlight that I have. And it would allow me to define a "master page" in Silverlight where I could host the menu. Do I have this right?

  • Is One Tool or a Suite of Tools Better for Scrum?

    - by Rob Wells
    G'day, Edit: We've been using Scrum very successfully for several years on several projects of varying sizes. In fact, our team developed the successful iPlayer project for the BBC using a classical Scrum approach. After using various combinations of tools, some high-tech, some low-tech, across these projects we now wish to try adopting a suitable tool suite. Our manager is to some extent attempting to force the adoption of a single suite of tools for Scrum. I've looked at the SO question "Best Scrum tools" and most people seem to recommend either: a suite of low-tech solutions, e.g. whiteboards, post-its, index cards, etc., or a monolithic tool that tries to satisfy as much as possible of the process, e.g. Agilo, Mingle, ScrumWorks, Target Process, etc. Our team is currently evaluating several different Scrum tools. However, we are looking at selecting a single, monolithic tool, e.g. Agilo. All of the "one-stop" solutions have their strengths and weaknesses with the serious enterprise type solutions being the best sort of fit. But all have some short comings. After reading the paper "Peer Code Review: An Agile Process" over at SmartBear I started wondering if we were trying to force adoption of a tool on a "best fit" basis. I think you can take a couple of reference artefacts of the Scrum development process, say user stories, epics and themes, and the code base which must use a well-known SCM, e.g. SVN, Hg, etc. Then if we take that as the common reference points for the tools employed then we would be able to use a group of tools to handle the different aspects of the Scrum process rather than try forcing a fit of a single tool would is a bit like forcing a square peg into the round hole. In this way, providing you've agreed your common reference points, you can use several tools, each performing their role better than a could be done by a single component in a monolithic tool suite. Is this a more sensible approach? Are the two reference points I mentioned above suitable, or is their a better choice of points where the tools would meet? cheers,

  • C# - Coding a nested stateflow diagram

    - by weberc2
    I have the following state diagram. I know how to make a simple state machine that transitions between non-nested states; however, I don't know how to transition between nested states. Could someone explain how to do this at an appropriately high level (i.e., you don't need to write the code for me--unless you're feeling particularly generous :P). State Diagram [EDIT: The bottom "A", "C", and "E" should be "B", "D", and "F" respectively; sorry!] What I know how to do public class MyState : State // State enumeration { public static MyState A = new MyState("State A"); public static MyState B = new MyState("State B"); public static MyState C = new MyState("State C"); public static MyState D = new MyState("State D"); public static MyState E = new MyState("State E"); public static MyState F = new MyState("State F"); public static MyState NEUT = new MyState("Neutral"); public static MyState P = new MyState("P"); protected MyState(string name) : base(name) { } } public class MyEvent : Event // Event enumeration { public static MyEvent X_POS = new MyEvent("X+"); public static MyEvent X_NEG = new MyEvent("X-"); public static MyEvent Y_POS = new MyEvent("Y+"); public static MyEvent Y_NEG = new MyEvent("Y-"); protected MyEvent(string name) : base(name) { } } public class MyStateMachine : StateMachine<MyState, MyEvent> // State Machine implementation { public MyStateMachine() : base(MyState.P) // MyState.P = initial state { // Set up the transition table // P this.addTransition(MYState.P, MyState.NEUT, MyEvent.Y_NEG); // NEUTRAL this.addTransition(MyState.NEUT, MyState.P, MyEvent.Y_POS); this.addTransition(MyState.NEUT, MyState.A, MyEvent.Y_NEG); this.addTransition(MyState.NEUT, MyState.B, MyEvent.Y_POS); this.addTransition(MyState.NEUT, MyState.C, MyEvent.Y_NEG); this.addTransition(MyState.NEUT, MyState.D, MyEvent.Y_POS); this.addTransition(MyState.NEUT, MyState.E, MyEvent.Y_NEG); this.addTransition(MyState.NEUT, MyState.F, MyEvent.Y_POS); // A this.addTransition(MyState.A, MyState.NEUT, MyEvent.Y_POS); // B this.addTransition(MyState.B, MyState.NEUT, MyEvent.Y_NEG); // C this.addTransition(MyState.C, MyState.NEUT, MyEvent.Y_POS); // D this.addTransition(MyState.D, MyState.NEUT, MyEvent.Y_NEG); // E this.addTransition(MyState.E, MyState.NEUT, MyEvent.Y_POS); // F this.addTransition(MyState.F, MyState.NEUT, MyEvent.Y_NEG); } public void move(MyEvent eevent) { try { this.moveNext(eevent); } catch (Exception e) { } } }
