• ADF Mobile Released!!

  - by Denis T

  ADFmfAnnounce We are pleased to announce the general availability of the newest version of Oracle’s ADF Mobile framework. This new framework provides the much anticipated on-device capabilities that the latest mobile applications require.  Feature Highlights Java - Oracle brings a Java VM embedded with each application so you can develop all your business logic in the platform neutral language you know and love! (Yes, even iOS!) JDBC - Since we give you Java, we also provide JDBC along with a SQLite driver and engine that also supports encryption out of the box. Multi-Platform - Truly develop your application only once and deploy to multiple platforms. iOS and Android platforms are supported for both phone and tablet. Flexible - You can decide how to implement the UI: (a) Use existing server-based UI framework like JSF. (b) Use your own favorite HTML5 framework like JQuery. (c) Use our declarative HTML5 component set provided with the framework. ADF Mobile XML or AMX for short, provides all the normal input and layout controls you expect and we also add charts/maps/gauges along with it to provide a very comprehensive UI controls. You can also mix and match any of the three for ultimate flexibility! Device Feature Access - You can get access to device features from either Java or JavaScript to invoke features like camera, GPS, email, SMS, contacts, etc. Secure - ADF Mobile provides integrated security that works with your server back-end as well. Whether you’re using remote URLs, local HTML or AMX, you can secure any/all of your features with a single consistent login page. Since we also give you SQLite encryption, we are assured that your data is safe. Rapid - Using the same development techniques that ADF developers are already used to, you can quickly create mobile applications without ever learning another language! Architecture ADF Mobile is a “hybrid” architecture that employs a natively built “container” on each platform that hosts a number of browser windows that are used to display the application content. We add the Java VM as a natively built library to the container for business logic.   How To Get Started ADF Mobile is an extension to the recently released JDeveloper version 11.1.2.3.0. Simple get the latest JDeveloper from Oracle Technology Network and use the Check for Updates feature to get the ADF Mobile extension. Note: ADF Mobile does not require developers to learn any other languages or frameworks but to build/deploy to iOS, you must be on an Apple MacintoshTM and have Xcode installed. To build/deploy to Android™ you must have the Android SDK installed.

• Response: Agile's Second Chasm

  - by Malcolm Anderson

  William Pietri over at Agile Focus has written an interesting article entitled, "Agile’s Second Chasm (and how we fell in)" in which he talks about how agile development has fallen into a common trap where large companies are now spending a lot of money hiring agile (Scrum) consultants just so that they can say they are agile, but all the while avoiding any change that is required by Scrum.   It echoes the questions that I've been asking for a while, "Can a fortune 500 company actually do agile development?"  I'm starting to think that the answer is "usually not"   William ask 3 questions at the end of his article that I will answer here.   1) Have I seen agile development brought in and then preemptively customized (read: made into ScrummerFall)?   Yes, Scrum is hard and disruptive.  It's a spotlight on company dysfunction.  In a low trust environment like most fortune 500 companies Scrum will be subverted by anyone who has ever seen "transparency" translate into someone being laid off.   2) If I had to do it all over again, would I change anything?  No, this is a natural progression, but the agile principles are powerful enough, that the companies that don't adopt them will no longer be competitive and will start to fail.   3) Is this situation solvable?  I think it is.  I think that one of the issues is that you often see companies implementing Scrum, but avoiding the agile engineering practices.  I believe that you cannot do one without the other.  Scrum keeps the ship sailing in smooth deep waters.  The agile engineering practices keep the engine running smoothly and cleanly.  If you implement agile engineering practices without Scrum, you run the risk of ending up with a great running piece of software that is useful to no one.  On the other hand, implementing cargo-cult Scrum without the agile engineering practices and you end up (especially in a fortune 500 company) being steered in the right direction, but with your development practices coming to a dead halt because you have code that can not keep up with the changes in requirements.   If you are trying to do Scrum, make sure that you hire some agile engineering coaches, or else you may find your deveolpment engines grinding to a dead halt in the middle of the open ocean.

• How do you go from a so so programmer to a great one? [closed]

  - by Cervo

  How do you go from being an okay programmer to being able to write maintainable clean code? For example David Hansson was writing Basecamp when in the process he created Rails as part of writing Basecamp in a clean/maintainable way. But how do you know when there is value in a side project like that? I have a bachelors in computer science, and I am about to get a masters and I will say that colleges teach you to write code to solve problems, not neatly or anything. Basically you think of a problem, come up with a solution, and write it down...not necessarily the most maintainable way in the world. Also my first job was in a startup, and now my third is in a small team in a large company where the attitude was/is get it done yesterday (also most of my jobs are mainly database development with SQL with a few ASP.NET web pages/.NET apps on the side). So of course cut/paste is more favored than making things more cleanly. And they would rather have something yesterday even if you have to rewrite it next month rather than to have something in a week that lasts for a year. Also spaghetti code turns up all over the place, and it takes very smart people to write/understand/maintain spaghetti code...However it would be better to do things so simple/clean that even a caveman/woman could do maintenance. Also I get very bored/unmotivated having to go modify the same things cut/pasted in a few locations. Is this the type of skill that you need to learn by working with a serious software organization that has an emphasis on maintenance and maybe even an architect who designs a system architecture and reviews code? Could you really learn it by volunteering on an open source project (it seems to me that a full time programmer job is way more practice than a few hours a week on an open source project)? Is there some course where you can learn this? I can attest that graduate school and undergraduate school do not really emphasize clean software at all. They just teach the structures/algorithms and then send you off into the world to solve problems. Overall I think the first thing is learning to write clean/maintainable code within the bounds of the project in order to become a good programmer. Then the next thing is learning when you need to do a side project (like a framework) to make things more maintainable/clean even while you still deliver things for the deadline in order to become a great programmer. For example, you are making an SQL report and someone gives you 100 calculations for individual columns. At what point does it make sense to construct a domain specific language to encode the rules in simply and then generate all the SQL as opposed to cut/pasting the query from the table a bunch of times and then adjusting each query to do the appropriate calculations. This is the type of thing I would say a great programmer would know. He/she would maybe even know ways to avoid the domain specific language and to still do all the calculations without creating an unmaintainable mess or a ton of repetitive code to cut/paste everywhere.

• Event-Driven Debugging

  - by Brian Donahue

  Most application troubleshooting involves getting an error, analyzing the error message, and at worst, attaching a debugger to work out the real cause. What is not really covered is how to troubleshoot an applicaiton that is not errant, but is having a performance issue, and more than likely, in the middle of the night when you are snug in your bed, sawing logs. What you need is an ever-vigilant cyborg who never sleeps to sit in front of your server all night, but as SkyNet is not live yet, you can settle for the next-best thing. Windows provides performance counters and alerts that can tell you when an applicaiton reaches an unacceptable threshold of naughty behavior, but although it can tattle on your brainchild, it won't be the child psychiatrist that you need to tell you why he's pulling your server's pigtails and pulling faces at the teacher. What you need is to plug a debugger into performance monitor and have it tell you what's going on with your applicaiton at the time. For this purpose, I'd used Microsoft's MDbgEngine as the basis for an applicaiton that will dump a program's stacks, I call it Application Slicer Dicer Wonder Dumper Super Cyborg, or StackOMatic for short. StackOMatic can look at a program's behavior and tell you if the stacks are not moving, but it can also work on the command-line to dump all managed methods on the stack at will. Now that there is a command you can use to dump the stacks, all you need to do is politely tell Windows to run it when you're displeased with your creation as it's trashing the CPU of your server at 3 AM. The first step is to create a scheduled task to tell StackOMatic to dump your applicaiton. Start Task Scheduler and right-click Task Scheduler Library and then Create Task. For this exercise I'm creating a task that will dump the Red Gate SQL Monitor Base Monitor Service. In the Actions tab, I enter the path to StackOMatic and use the arguments to log the stack dump to a file: /PN:RedGate.Response.Engine.Alerting.Base.Service /OUT:c:\users\administrator\MonitorLog.txt Next, I go into Windows Server 2008's Reliability and Performance Monitor and add a new Data Collector Set. This set will produce an alert on the %Processor Time for the service. When the processor time breaches 50%, it will run the StackDumpBaseService task I created. Whenever the service misbehaves, it will append to the log file. Now when I go to work in the morning, I can see what the service was doing when it overloaded the processor and take action.

• Help yourself . if you like

  - by rachelp

  At Red Gate we enjoy talking to our customers. Really! If you've read recent blog posts by members of some of our customer-facing teams, you'll have spotted the pleasure they take in their work. In case you missed those posts, here they are: From our Finance team: Finance: Friends, not foes! From our reception desk: The Front line of Communication However, we recognise that sometimes our customers would like to be able to solve their problems or answer their questions without talking to us - they're in a hurry, it's outside office hours . or perhaps they just prefer not to pick up the phone and call.   Self-service customer care So we've begun a programme of work to enable more self-service; whether it's finding the answer to a "how do i.?" question or getting access to a record of what product licenses they own, we want to make it much easier for our customers to get hold of this information for themselves. If they want to.   Phase 1: make it easier to find information We decided to start by tackling findability. We've got loads of useful information on our website, but it's sometimes difficult to find, so we've been working on improving our site search. Step 1 has been to replace the search engine, clean up the search UI, and make it consistent across the site. We're nearly there! The idea is that if we improve the site search it will be easier - and much more pleasant - for people to find the information they need. The new search will go live some time in April, and then we'll be gathering feedback, looking at web analytics (more about this in an earlier article), and working out what improvements we still need to make. We'd love to hear what you think, so do give your feedback or drop us a line. Or pick up the phone and call, if you like.   What do you think? While I've got your attention, I'd love to hear what people think about self-service customer care. Do you like to call, email, live chat . or do you prefer to dig around and find out answers yourself? Who's getting it right: what self-service sites do you like? p.s. Watch this space for news of phase 2.

• Want to make RTS strategy game, good starting point...?

  - by NOLANDI

  everybody! I find this community because I did research about game developing topics. So I decide to register on this community and ask for your opinion. I am not begineer in computer stuffs, and I know logic of programming language. I have little knowlegde of C, C++, Started to learn C#...but I was always oriented about other areas of IT. Amateur for game making but not in IT general! I am interested to make RTS strategy video game, isometric camera view (like PC GAME COMMANDOS for example)...so I started to read many books about DirectX, XNA, OpenGL, C#, AI programming...so I want to know where is good starting point for making this game genre. I want to use C# for this project, not C++, since I always had trouble with it, because it is too complicated. I see good oportunity for learning C#, since it has more object-oriented concept, with much less code and easy readible code for writing. Beside of that I know that C++ is the more powerful language until today. So I want to use DirectX and C# for my project. But it will required more time for sure, to learn it. I have trouble with finding books for c# & DirectX (I found just one), but in every next book, it is programming in c++! I read many web sites and they mentioned Slim DX, and in generaly, other articles which I read tells that it is possible to make good game with combination c# and directX, but...I don't have enough information about all this stuffs, so I became confused! It is really hard to have wish to learn c++ from scratch, since I started c# and I like it really...I don't try OpenGL, but I am already familiar with DirectX (some beginning stuffs), and I think that it is good and interesting. So, I decide to choose between maybe Unity3d and XNA first. XNA...hm, it sound that it is not bad solution, but I heard that it is already overcome technology, and I think that it is better to wait with XNA, until I try to make something with DirectX and C#, at first. But I dont know it is possible to make strategy game in XNA?! Maybe I am wrong. I also, find Unity 3D game engine and I find that I could programming there in C#, but many all examples are written in Javascript (Digital tutors videos)...But I generaly have wish to learn it too, because it allows to export games to mobile phones, there a lot of documentations, it is free, etc... I want to find best way to learn C# and DirectX, and make this game, but I dont know if it's possible to combine?! But maybe is good to first try Unity and XNA, because I am beginner?! Thank you all! I am willing to hear your expirience.

• WCF ChannelFactory caching

  - by Myles J

  I've just read this great article on WCF ChannelFactory caching by Wenlong Dong. My question is simply how can you actually prove that the ChannelFactory is in fact being cached between calls? I've followed the rules regarding the ClientBase’s constructors. We are using the following overloaded constructor on our object that inherits from ClientBase: ClientBase(string endpointConfigurationName, EndpointAddress remoteAddress); In the article mentioned above it is stated that: For these constructors, all arguments (including default ones) are in the following list: · InstanceContext callbackInstance · string endpointConfigurationName · EndpointAddress remoteAddress As long as these three arguments are the same when ClientBase is constructed, we can safely assume that the same ChannelFactory can be used. Fortunately, String and EndpointAddress types are immutable, i.e., we can make simple comparison to determine whether two arguments are the same. For InstanceContext, we can use Object reference comparison. The type EndpointTrait is thus used as the key of the MRU cache. To test the ChannelFactory cache theory we are checking the Hashcode in the ClientBase constructor e.g. var testHash = RuntimeHelpers.GetHashCode(base.ChannelFactory); The hash value is different between calls which makes us think that the ChannelFactory isn't actually cached. Any thoughts? Regards Myles

• Using Visual Studio 2008 to Assemble, Link, Debug, and Execute MASM 6.11 Assembly Code

  - by Kreychek

  I would like to use Visual Studio 2008 to the greatest extent possible while effectively compiling/linking/building/etc code as if all these build processes were being done by the tools provided with MASM 6.11. The exact version of MASM does not matter, so long as it's within the 6.x range, as that is what my college is using to teach 16-bit assembly. I have done some research on the subject and have come to the conclusion that there are several options: Reconfigure VS to call the MASM 6.11 executables with the same flags, etc as MASM 6.11 would natively do. Create intermediary batch file(s) to be called by VS to then invoke the proper commands for MASM's linker, etc. Reconfigure VS's built-in build tools/rules (assembler, linker, etc) to provide an environment identical to the one used by MASM 6.11. Option (2) was brought up when I realized that the options available in VS's "External Tools" interface may be insufficient to correctly invoke MASM's build tools, thus a batch file to interpret VS's strict method of passing arguments might be helpful, as a lot of my learning about how to get this working involved my manually calling ML.exe, LINK.exe, etc from the command prompt. Below are several links that may prove useful in answering my question. Please keep in mind that I have read them all and none are the actual solution. I can only hope my specifying MASM 6.11 doesn't prevent anyone from contributing a perhaps more generalized answer. Similar method used to Option (2), but users on the thread are not contactable: http://www.codeguru.com/forum/archive/index.php/t-284051.html (also, I have my doubts about the necessity of an intermediary batch file) Out of date explanation to my question: http://www.cs.fiu.edu/~downeyt/cop3402/masmaul.html Probably the closest thing I've come to a definitive solution, but refers to a suite of tools from something besides MASM, also uses a batch file: http://www.kipirvine.com/asm/gettingStarted/index.htm#16-bit I apologize if my terminology for the tools used in each step of the code - exe process is off, but since I'm trying to reproduce the entirety of steps in between completion of writing the code and generating an executable, I don't think it matters much.

• SCons does not clean all files

  - by meowsqueak

  I have a file system containing directories of "builds", each of which contains a file called "build-info.xml". However some of the builds happened before the build script generated "build-info.xml" so in that case I have a somewhat non-trivial SCons SConstruct that is used to generate a skeleton build-info.xml so that it can be used as a dependency for further rules. I.e.: for each directory: if build-info.xml already exists, do nothing. More importantly, do not remove it on a 'scons --clean'. if build-info.xml does not exist, generate a skeleton one instead - build-info.xml has no dependencies on any other files - the skeleton is essentially minimal defaults. during a --clean, remove build-info.xml if it was generated, otherwise leave it be. My SConstruct looks something like this: def generate_actions_BuildInfoXML(source, target, env, for_signature): cmd = "python '%s/bin/create-build-info-xml.py' --version $VERSION --path . --output ${TARGET.file}" % (Dir('#').abspath,) return cmd bld = Builder(generator = generate_actions_BuildInfoXML, chdir = 1) env.Append(BUILDERS = { "BuildInfoXML" : bld }) ... # VERSION = some arbitrary string, not important here # path = filesystem path, set elsewhere build_info_xml = "%s/build-info.xml" % (path,) if not os.path.exists(build_info_xml): env.BuildInfoXML(build_info_xml, None, VERSION = build) My problem is that 'scons --clean' does not remove the generated build-info.xml files. I played around with env.Clean(t, build_info_xml) within the 'if' but I was unable to get this to work - mainly because I could not work out what to assign to 't' - I want a generated build-info.xml to be cleaned unconditionally, rather than based on the cleaning of another target, and I wasn't able to get this to work. If I tried a simple env.Clean(None, "build_info_xml") after but outside the 'if' I found that SCons would clean every single build-info.xml file including those that weren't generated. Not good either. What I'd like to know is how SCons goes about determining which files should be cleaned and which should not. Is there something funny about the way I've used a generator function that prevents SCons from recording this target as a Clean candidate?

• 301 Redirect adding incorrect extra segments to a url

  - by Pentland_web

  I need to 301 redirect one segment of a url to a new version of it. My aim is redirect www.domain.co.uk/farm/whatever/ to www.domain.co.uk/farm_cottages/whatever/ The rule I am using to do this is: RedirectMatch 301 ^/farm/ /farm_cottages/ However for some reason it partially works but appends ?/farm/ after farm_cottages/ in the final url ie. www.domain.co.uk/farm_cottages/?/farm/whatever/ Here is my entire rewrite rule set as I believe one of the rewrite rules could be interfering with the redirect rule. #redirect /farm/ to /farm_cottages/ RedirectMatch 301 ^/farm/ /farm_cottages/ <IfModule mod_rewrite.c> RewriteEngine on # no WWW to WWW RewriteCond %{HTTP_HOST} !^www.domain.co.uk$ [NC] RewriteRule ^(.*)$ http://www.domain.co.uk/$1 [R=301,L] # Force trailing slash on URLs RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} !(.*)/$ RewriteRule ^(.*)$ http://www.domain.co.uk/$1/ [L,R=301] #Remove index.php RewriteCond $1 !\.(gif|jpe?g|png)$ [NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /index.php?/$1 [L] RewriteCond %{THE_REQUEST} ^[^/]*/index\.php [NC] RewriteRule ^index\.php(.+) $1 [R=301,L] </IfModule> The site is built in Expressionengine and so the segments of url do not represent actual folders - I don't think this should matter though. Any ideas would be much appreciated! Thanks

• DRY Validation with MVC2

  - by Matthew

  Hi All, I'm trying to figure out how I can define validation rules for my domain objects in one single location within my application but have run in to a snag... Some background: My location has several parts: - Database - DAL - Business Logic Layer - SOAP API Layer - MVC website The MVC website accesses the database via the SOAP API, just as third parties would. We are using server and and client side validation on the MVC website as well as in the SOAP API Layer. To avoid having to manually write client side validation we are implementing strongly typed views in conjunction with the Html.TextBoxFor and Html.ValidationMessageFor HTML helpers, as shown in Step 3 here. We also create custom models for each form where one form takes input for multiple domain objects. This is where the problem begins, the HTML helpers read from the model for the data annotation validation attributes. In most cases our forms deal with multiple domain objects and you can't specify more than one type in the <%@Page ... Inherits="System.Web.Mvc.ViewPage" % page directive. So we are forced to create a custom model class, which would mean duplicating validation attributes from the domain objects on to the model class. I've spent quite some time looking for workarounds to this, such has referencing the same MetadataType from both the domain class and the custom MVC models, but that won't work for several reasons: You can only specify one MetadataType attribute per class, so its a problem if a model references multiple domain objects, each with their own metadata type. The data annotation validation code throws an exception if the model class doesn't contain a property that is specified in the referenced MetadataType which is a problem with the model only deals with a subset of the properties for a given domain object. I've looked at other solutions as well but to no avail. If anyone has any ideas on how to achieve a single source for validation logic that would work across MVC client and server side validation functionality and other locations (such as my SOAP API) I would love to hear it! Thanks in advance, Matthew

• What is best practice as far as using perl-isms (idiomatic expressions) in Perl?

  - by DVK

  A couple of years back I participated in writing the best practices/coding style for our (fairly large and often Perl-using) company. It was done by a committee of "senior" Perl developers. As anything done by consensus, it had parts which everyone disagreed with. Duh. The part that rubbed wrong the most was a strong recommendation to NOT use many Perlisms (loosely defined as code idioms not present in, say C++ or Java), such as "Avoid using '... unless X;' constructs". The main rationale posited for such rules as this one was that non-Perl developers would have much harder time with the Perl code base otherwise. The assumption here I guess is that Perl code jockeys are rarer breed overall - and among new hires to the company - than non-Perlers. I was wondering whether SO has any good arguments to support or reject this logic... it is mostly academic curiosity at this point as the company's Perl coding standard is ossified and will never be revised again as far as I'm aware. P.S. Just to be clear, the question is in the context I noted - the answer for an all-Perl smaller development shop is obviously a resounding "use Perl to its maximum capability".

• Using IIS Application Request Routing (ARR) for ASP.NET MVC

  - by Malcolm Frexner

  I use a simple ASP.NET MVC web (the template you use when you create a new site) and the web works as expected in my live environment. I now try to use IIS Application Request Routing version 2. I have a rule that send all reuqests to a different server that match a rule. The settings are a bit like this: http://blogs.iis.net/wonyoo/archive/2008/07/09/application-request-routing-arr-as-a-reverse-proxy.aspx My rule is just a bit different it is /shop(.*). Only requests that contain shop are send to a different server. I have to use rewrite, not redirect (The same as in the Picture) This works as long as the web the original requests go to is no ASP.NET MVC web. I tried to use a plain htm file in the webfolder and it worked. If put a compiled ASP.NET application into the webfolder it worked. But as soon as I put an ASP.NET MVC web into the folder, request arr served by this application. My understanding is that the ARR should kick in before the web application gets the chance to handle the request. Did anybody use ARR sucessfully as a reverse proxy for a ASP.NET MVC web? EDIT Here is the resulting web config when the rewrite roule is entered.

• Using jquery validate with multiple fields of the same name

  - by Matt H

  I am trying to get jquery validate to work on multiple fields. Reason being I have dynamically generated fields added and they are simply a list of numbers. So I thought I'd put together a basic example and followed the concept from the accepted answer in the following link: http://stackoverflow.com/questions/931687/using-jquery-validate-plugin-to-validate-multiple-form-fields-with-identical-name However, it's not doing anything useful. Why is it not working? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <script src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript" src="http://dev.jquery.com/view/trunk/plugins/validate/lib/jquery.delegate.js"></script> <script type="text/javascript" src="http://dev.jquery.com/view/trunk/plugins/validate/jquery.validate.js"></script> <script> $("#submit").click(function(){ $("field").each(function(){ $(this).rules("add", { required: true, email: true, messages: { required: "Specify a valid email" } }); }) }); $(document).ready(function(){ $("#myform").validate(); }); </script> </head> <body> <form id="myform"> <label for="field">Required, email: </label> <input class="left" id="field" name="field" /> <input class="left" id="field" name="field" /> <input class="left" id="field" name="field" /> <input class="left" id="field" name="field" /> <br/> <input type="submit" value="Validate!" id="submit" name="submit" /> </form> </body> </html>

• Spring MVC jQuery remote validation

  - by raulsan

  Hi, I am using Spring MVC on the server side, but in one of the pages I decided to create an AJAX validation with jQuery rather than the default Spring validation. Everything works great, except when I have to do a remote validation to check if a "title" already exists. For the javascript I have the following: var validator = $("form").validate({ rules: { title: { minlength: 6, required: true, remote: { url: location.href.substring(0,location.href.lastIndexOf('/'))+"/checkLocalArticleTitle.do", type: "GET" } }, html: { minlength: 50, required: true } }, messages: { title: { required: "A title is required.", remote: "This title already exists." } } }); Then, I use Spring-Json to make this validation and give a response: @RequestMapping("/checkLocalArticleTitle.do") public ModelAndView checkLocalArticleTitle(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { Map model = new HashMap(); String result = "FALSE"; try{ String title = request.getParameter("title"); if(!EJBRequester.articleExists(title)){ result = "TRUE"; } }catch(Exception e){ System.err.println("Exception: " + e.getMessage()); } model.put("result",result); return new ModelAndView("jsonView", model); } However, this does not work and the field "title" is never validated. I think the reason for this is that I am returning an answer in the manner: {result:"TRUE"} when in fact, the answer should be: {"TRUE"} I don't know how to return a single response like this one using a ModelAndView answer. Another thing that is not working is the customized message for the "remote" validation: messages: { title: { required: "A title is required.", remote: "This title already exists." } }, The required message works, but not the remote message. I looked around, but I didn't see many people using Spring and jQuery at the same time. I would appreciate some help here.

• Ivar definitions show 'long' type encoding as 'long long' type encoding

  - by Frank C.

  I've found what I think may be a bug with Ivar and Objective-C runtime. I'm using XCode 3.2.1 and associated libraries, developing a 64 bit app on X86_64 (MacBook Pro). Where I would expect the type encoding for the following "longVal" to be 'l', the Ivar encoding is showing a 'q' (which is a 'long long'). Anyone else seeing this? Simplified code and output follows: Code: #import <Foundation/Foundation.h> #import <objc/runtime.h> @interface Bug : NSObject { long longVal; long long longerVal; } @property (nonatomic,assign) long longVal; @property (nonatomic,assign) long long longerVal; @end @implementation Bug @synthesize longVal,longerVal; @end int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; unsigned int ivarCount=0; Ivar *ivars= class_copyIvarList([Bug class], &ivarCount); for(unsigned int x=0;x<ivarCount;x++) { NSLog(@"Name [%@] encoding [%@]", [NSString stringWithCString:ivar_getName(ivars[x]) encoding:NSUTF8StringEncoding], [NSString stringWithCString:ivar_getTypeEncoding(ivars[x]) encoding:NSUTF8StringEncoding]); } [pool drain]; return 0; } And here is output from debug console: This GDB was configured as "x86_64-apple-darwin".tty /dev/ttys000 Loading program into debugger… sharedlibrary apply-load-rules all Program loaded. run [Switching to process 6048] Running… 2010-03-17 22:16:29.138 ivarbug[6048:a0f] Name [longVal] encoding [q] 2010-03-17 22:16:29.146 ivarbug[6048:a0f] Name [longerVal] encoding [q] (gdb) continue Not a pretty picture! -- Frank

• JQuery Validate: only takes the last addMethod?

  - by Neuquino

  Hi, I need to add multiple custom validations to one form. I have 2 definitions of addMethod. But it only takes the last one... here is the code. $(document).ready(function() { $.validator.addMethod("badSelectionB",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_B_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) == -1){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $.validator.addMethod("badSelectionA",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_A_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) == -1){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $("#inscripcionForm").validate( { rules : { nombre : "required", apellido : "required", dni : { required: true, digits: true, }, mail : { required : true, email : true, }, comision_A_6: { badSelectionA:true, }, comision_B_6: { badSelectionB: true, } }, messages : { nombre : "Ingrese su nombre.", apellido : "Ingrese su apellido.", dni : { required: "Ingrese su dni.", digits: "Ingrese solo números.", }, mail : { required : "Ingrese su correo electrónico.", email: "El correo electrónico ingresado no es válido." } }, }); }); Do you have any clue of what is happening? Thanks in advance,

• Getting MSDeploy working on our build/integration server - Is an MSBuild upgrade necessary?

  - by Jeff D

  We have what I think is a fairly standard build process: 1. Developer: Check in code 2. Build: Polls repo, sees change, and kicks off build that: 3. Build: Updates from repo, Builds w/ MSBuild, Runs unit tests w/ nunit, 4. Build: creates installer package Our security team allows us to pull from the build server, but does not allow the build server to push. So we generally rdp in, d/l the installers, and run them, which rules out the slick deployment services, so I would need to generate packages instead. I'd like to use MSDeploy, except that we have the following issues: We're on .net 3.5, and the MSBuild target (Package) that uses MSDeploy requires 4.0. Is there anything I'd need to install other than .net 4.0 RC for this? (Would MSBuild be part of that upgrade?) When I generate packages with MSDeploy, I see that I don't have just 1 file. There's a zip, deploy.cmd, SourceManifest.xml, and SetParameters.xml. What are all the other files for, and why wouldn't they all be in the 'package'? It sounds as if you can create packages by telling the system to look at a working IIS site. But if the packages are build from a CI environment, aren't you basically out of luck here? It feels like they designed some of this for small-scale developers deploying from their dev environment. That's a fine use case, but I'm interested in see what everyone's enterprise-experience is with the tool Any suggestions?

• Support for nested model and class validation with ASP.NET MVC 2.0

  - by Diep-Vriezer

  I'm trying to validate a model containing other objects with validation rules using the System.ComponentModel.DataAnnotations attributes was hoping the default MVC implementation would suffice: var obj = js.Deserialize(json, objectInfo.ObjectType); if(!TryValidateModel(obj)) { // Handle failed model validation. } The object is composed of primitive types but also contains other classes which also use DataAnnotications. Like so: public class Entry { [Required] public Person Subscriber { get; set; } [Required] public String Company { get; set; } } public class Person { public String FirstName { get; set;} [Required] public String Surname { get; set; } } The problem is that the ASP.NET MVC validation only goes down 1 level and only evaluates the properties of the top level class, as can be read on digitallycreated.net/Blog/54/deep-inside-asp.net-mvc-2-model-metadata-and-validation. Does anyone know an elegant solution to this? I've tried xVal, but they seem to use a non-recursive pattern (http://blog.stevensanderson.com/2009/01/10/xval-a-validation-framework-for-aspnet-mvc/). Someone must have run into this problem before right? Nesting objects in your model doesn't seem so weird if you're designing a web service.

• Boosting my GA with Neural Networks and/or Reinforcement Learning

  - by AlexT

  As I have mentioned in previous questions I am writing a maze solving application to help me learn about more theoretical CS subjects, after some trouble I've got a Genetic Algorithm working that can evolve a set of rules (handled by boolean values) in order to find a good solution through a maze. That being said, the GA alone is okay, but I'd like to beef it up with a Neural Network, even though I have no real working knowledge of Neural Networks (no formal theoretical CS education). After doing a bit of reading on the subject I found that a Neural Network could be used to train a genome in order to improve results. Let's say I have a genome (group of genes), such as 1 0 0 1 0 1 0 1 0 1 1 1 0 0... How could I use a Neural Network (I'm assuming MLP?) to train and improve my genome? In addition to this as I know nothing about Neural Networks I've been looking into implementing some form of Reinforcement Learning, using my maze matrix (2 dimensional array), although I'm a bit stuck on what the following algorithm wants from me: (from http://people.revoledu.com/kardi/tutorial/ReinforcementLearning/Q-Learning-Algorithm.htm) 1. Set parameter , and environment reward matrix R 2. Initialize matrix Q as zero matrix 3. For each episode: * Select random initial state * Do while not reach goal state o Select one among all possible actions for the current state o Using this possible action, consider to go to the next state o Get maximum Q value of this next state based on all possible actions o Compute o Set the next state as the current state End Do End For The big problem for me is implementing a reward matrix R and what a Q matrix exactly is, and getting the Q value. I use a multi-dimensional array for my maze and enum states for every move. How would this be used in a Q-Learning algorithm? If someone could help out by explaining what I would need to do to implement the following, preferably in Java although C# would be nice too, possibly with some source code examples it'd be appreciated.

• SSRS 2008: is it possible to make a report parameter NOT query-based for some linked report?

  - by Stefan Mohr

  I suspect the answer is no, but here goes.. I'm using the WebForms Report Viewer on a public-facing website to allow users to report on themselves or their users (if the user is an admin user). A report has a parameter called Users where an admin can pick a user from the list and generate a report from it. Mundane users can also view this report, but I programmatically create a linked report for each user and set the UserID value to their ID so they can only view themselves. This works well except that the UserID parameter is query-based, and not every user is visible in the list using default settings (the user list is based off date range parameters can provide, and only users we consider 'active' during the date range are visible). This is blowing up for mundane users that are not active for the default date range (which is the previous month). I suspect the flow of execution is something like this: Report loads with default parameters The linked report rules are now applied and the value of the UserID is overridden with the ID in the linked report UserID field is now hidden to prevent the user from changing it SSRS can't find the UserID default value in the query results (that I didn't even want it to run) so it displays an error The 'UserID' parameter is missing a value Through some testing I've found a perfect correlation between users not inside the default date range and users who can't view the report. Can anyone suggest a way to make the report usable for those users that aren't in the default list? The reports are created programmatically so I do have a fair bit of control over the situation. I would love to simply be able to mark a parameter in a linked report as no longer being query-based, but those properties are all read-only. I really, really don't want to have to create duplicate reports to accommodate these users but I'm at a bit of a loss right now. Any suggestions are greatly appreciated!

• Complex SQL Query similar to a z order problem

  - by AaronLS

  I have a complex SQL problem in MS SQL Server, and in drawing on a piece of paper I realized that I could think of it as a single bar filled with rectangles, each rectangle having segments with different Z orders. In reality it has nothing to do with z order or graphics at all, but more to do with some complex business rules that would be difficult to explain. Howoever, if anyone has ideas on how to solve the below that will give me my solution. I have the following data: ObjectID, PercentOfBar, ZOrder (where smaller is closer) A, 100, 6 B, 50, 5 B, 50, 4 C, 30, 3 C, 70, 6 The result of my query that I want is this, in any order: PercentOfBar, ZOrder 50, 5 20, 4 30, 3 Think of it like this, if I drew rectangle A, it would fill 100% of the bar and have a z order of 6. 66666666666 AAAAAAAAAAA If I then layed out rectangle B, consisting of two segments, both segments would cover up rectangle A resulting in the following rendering: 4444455555 BBBBBBBBBB As a rule of thumb, for a given rectangle, it's segments should be layed out such that the highest z order is to the right of the lower Z orders. Finally rectangle C would cover up only portions of Rectangle B with it's 30% segment that is z order 3, which would be on the left. You can hopefully see how the is represented in the output dataset I listed above: 3334455555 CCCBBBBBBB Now to make things more complicated I actually have a 4th column such that this grouping occurs for each key: Input: SomeKey, ObjectID, PercentOfBar, ZOrder (where smaller is closer) X, A, 100, 6 X, B, 50, 5 X, B, 50, 4 X, C, 30, 3 X, C, 70, 6 Y, A, 100, 6 Z, B, 50, 2 Z, B, 50, 6 Z, C, 100, 5 Output: SomeKey, PercentOfBar, ZOrder X, 50, 5 X, 20, 4 X, 30, 3 Y, 100, 6 Z, 50, 2 Z, 50, 5 Notice in the output, the PercentOfBar for each SomeKey would add up to 100%. This is one I know I'm going to be thinking about when I go to bed tonight. Just to be explicit and have a question: What would be a query that would produce the results described above?

• Tables created programmatically don't appear in WebBrowser control

  - by John Hall

  I'm creating HTML dynamically in a WebBrowser control. Most elements seems to appear correctly, with the exception of a table. My code is: var doc = webBrowser1.Document; var body = webBrowser1.Document.Body; body.AppendChild(webBrowser1.Document.CreateElement("hr")); var div = doc.CreateElement("DIV"); var table = doc.CreateElement("TABLE"); var row1 = doc.CreateElement("TR"); var cell1 = doc.CreateElement("TD"); cell1.InnerText = "Cell 1"; row1.AppendChild(cell1); var cell2 = doc.CreateElement("TD"); cell2.InnerText = "Cell 2"; row1.AppendChild(cell2); table.AppendChild(row1); div.AppendChild(table); body.AppendChild(div); body.AppendChild(webBrowser1.Document.CreateElement("hr")); The HTML tags are visible in the OuterHTML property of the body, but all that appears in the browser are the two horizontal rules. If I replace div.AppendChild(table); with div.InnerHtml = table.OuterHtml then everything appears as expected.
