• URL valid characters. java to validate.

  - by Chez

  a string like: 'www.test.com' is good. a string like: 'www.888.com' is good. a string like: 'stackoverflow.com' is good. a string like: 'GOoGle.Com' is good. why ? because those are valid urls. it does not necessarely matter if they have been registered or not. now bad strings are: 'goog*d\x' 'manydots...com' why because you can't register those urls. if I have a string in java which is supposed to be a good url what's the best way to validate it ? thanks a lot

• Jquery ajax load of JSON in unit tests

  - by wmitchell

  I'm trying to load a dataset in jasmine for my tests like such ... However as its a json call I cant seem to always get the test denoted by "it" to wait till the JSON call has finished before using its array. I tried using the ajaxStop function to no avail. Any ideas ? describe("simple checks", function() { var exampleArray = new Array(); beforeEach(function(){ $(document).ajaxStop(function() { $(this).unbind("ajaxStop"); $.getJSON('/jasmine/obj.json', function(data) { $.each( json.jsonattr, function(i, widgetElement) { exampleArray.push(new widget(widgetElement)); }); }); }); }); it("use the exampleArray", function() { doSomething(exampleArray[0]); // frequently this is coming up as undefined });

• Xhtml instead of Php?

  - by ihaveitnow

  I want to develop a site that will allow be to publish information to users, and give them and opportunity to subscribe to a mailing list so they can be updated each time I make a change to the site. *Add new information, etc. I also would like for the users to be able to add comments about reviews posted, and give me suggestions...Things that will encourage user interaction I understand that this is possible with php... But I do not know php, and to learn and test it I apparently need a domain to begin with...etc. Is it possible that I use Xhtml/Html to get the same results? -- I know I can use the <a href="mailto:[email protected]"; subject="Email from Site user">Mail</a> but that would also leave my email open to spam...Any suggestions? And I do apologize if this question has been posted before, I did some research and found no such thing. All helpful responses are appreciated.

• Java regex basic usage problem

  - by Ernelli

  The following code works: String str= "test with foo hoo"; Pattern pattern = Pattern.compile("foo"); Matcher matcher = pattern.matcher(str); if(matcher.find()) { ... } But this example does not: if(Pattern.matches("foo", str)) { ... } And neither this version: if(str.matches("foo")) { ... } In the real code, str is a chunk of text with multiple lines if that is treated differently by the matcher, also in the real code, replace will be used to replace a string of text. Anyway, it is strange that it works in the first version but not the other two versions.

• Best Practices for Content Types in SharePoint

  - by Anna Karin

  Hi all, Recently, we came across a severe problem in production farm with the Content Types. I would like to explain the background of this problem first. We have nice working feature for Content Types installation in production and test farms. We developed and deployed (using wsps) this SharePoint feature in Visual studio. We are using the publishing pages using page layouts and Content Types to help content editors to quickly publish the web pages. Unfortunately, some Content Types have been manually updated/added by some people in the production, so whenever I (developer) make some changes to the existing Content Types (using Visual Studio and feature activation/deactivation) , SharePoint removes one or two columns (during feature activation/deactivation) from Content Types; or the columns which have not been added in a best practice way. I think the best practice is to update Content Types using Visual Studio. Now, I wish to ensure that site columns shouldn't get removed from Content Types upon feature activation/deactivation. Note: Our feature for Content Type activation/deactivation doesn't hold any activation dependencies in the feature.xml

• Numpy modify array in place?

  - by User

  I have the following code which is attempting to normalize the values of an m x n array (It will be used as input to a neural network, where m is the number of training examples and n is the number of features). However, when I inspect the array in the interpreter after the script runs, I see that the values are not normalized; that is, they still have the original values. I guess this is because the assignment to the array variable inside the function is only seen within the function. How can I do this normalization in place? Or do I have to return a new array from the normalize function? import numpy def normalize(array, imin = -1, imax = 1): """I = Imin + (Imax-Imin)*(D-Dmin)/(Dmax-Dmin)""" dmin = array.min() dmax = array.max() array = imin + (imax - imin)*(array - dmin)/(dmax - dmin) print array[0] def main(): array = numpy.loadtxt('test.csv', delimiter=',', skiprows=1) for column in array.T: normalize(column) return array if __name__ == "__main__": a = main()

• treating json like an array

  - by tawheed

  I was doing some test with json and ran into serveral issues. hope somebody on this mailing list can help out. localStorage[LOC] = JSON.stringify(track); var boy = localStorage[LOC]; alert(boy); This is the data I get back [{"lat":42.5877511,"lng":-71.7873177,"acc":67,"date":"Sat Apr 14 2012 01:03:46 GMT-0400 (EDT)"}] I was wondering how I could access the json objects like we do in a regular array. For debugging purposes I did something like, alert(boy[0].lat); But the result I got back was undefined

• ASP.NET and SQL server with huge data sets

  - by Jake Petroules

  I am developing a web application in ASP.NET and on one page I am using a ListView with paging. As a test I populated the table it draws from with 6 million rows. The table and a schema-bound view based off it have all the necessary indexes and executing the query in SQL Server Management Studio with SELECT TOP 5 returned in < 1 second as expected. But on the ASP.NET page, with the same query, it seems to be selecting all 6 million rows without any limit. Shouldn't the paging control limit the query to return only N rows rather than the entire data set? How can I use these ASP.NET controls to handle huge data sets with millions of records? Does SELECT [columns] FROM [tablename] quite literally mean that for the ListView, and it doesn't actually inject a TOP <n> and does all the pagination at the application level rather than the database level?

• How to find item selected from customContextMenuRequested() on QTreeView item?

  - by vinaym

  I have implemented contextual menus in QTreeView items with the following code MyDerivedQTreeView->setModel(MyDerivedQAbstractItemModel); MyDerivedQTreeView->setContextMenuPolicy(Qt::CustomContextMenu); connect(MyDerivedQTreeView, SIGNAL(customContextMenuRequested(const QPoint &)), MyDerivedQAbstractItemModel(), SLOT(contextualMenu(const QPoint &))); void MyDerivedQAbstractItemModel::contextualMenu(const QPoint& point) { QMenu *menu = new QMenu; menu->addAction(QString("Test Item"), this, SLOT(test_slot())); menu->exec(MyDerivedQTreeView->mapToGlobal(point)); } MyDerivedQAbstractItemModel::contextualMenu() gets called and I can see the contextual menu. Problem is contextual menu should be visible only if user right-clicks on an item and it should be customized as per the item selected. How do I get whether/which item is selected from QPoint information? I am on Qt 4.5.3.

• Develop applications to mobiles

  - by muek

  Hi there, I have very easy question, but I simply have any idea of the answer. I have developed a small mobile-application using java, for my nokia. The problem is that when installed on my samsung the application simply crashed. Then I tried on my other nokia but different model, and I didn't got the normal behavior. So my question is, does anyone have any idea how companies that develop mobiles applications/games test their software. Does they have to have all models for all mobiles phones??

• JTextArea thread safe?

  - by Dhaivat Pandya

  Hello everyone, I have some code that does some initialization (including making a JTextArea object), starts three seperate threads, and then these threads try to update the JTextArea (i.e. append() to it), but its not working at all. Nothing shows up on the JTextArea (however, during the initialzation, I print some test lines onto it, and that works fine). What's going on? How can I fix this? Also, each of those threads sleeps a random amount of time every time it has to update the JTextArea. Sorry I haven't provided any code, its all spread out over several files.

• Why compressed xps are corrupt?

  - by Gio

  compressed xps documents do not pass isxps.exe test and do not display in xpsviewer. i'm using Windows 7 and vs2010. Dim ms = New MemoryStream() Dim P As Package = Package.Open(ms, FileMode.Create, FileAccess.ReadWrite) Dim DocumentUri As Uri = New Uri("pack://document.xps") PackageStore.AddPackage(DocumentUri, P) Dim document As XpsDocument = New XpsDocument(P, CompressionOption.Maximum, DocumentUri.AbsoluteUri) If i change CompressionOption.Maximum to CompressionOption.None all works perfectly. IsXps.exe says "Unable to open Zip archive Error code: 0x8000FFFF", same with default W7 XpsViewer. what i'm doing wrong? (i've also installed latest 7zip program, but i do not think that it may corrupt the default windows zip capability......or not?)

• Configuring Warden for use in RSpec controller specs

  - by Chris Peters

  I was able to use Devise's sign_in method to log in a user in my controller specs. But now that I'm removing Devise from my application, I'm not quite sure how to get similar functionality working with just Warden on its own. How should I go about setting up spec/spec_helper.rb and related spec/support/*.rb files to get Warden running within controller specs sufficiently? I've tried setting up a file at spec/support/warden.rb with these contents: RSpec.configure do |config| config.include Warden::Test::Helpers config.after do Warden.test_reset! end end Then I have before calls similar to this to authenticate a user factory: before { login_as FactoryGirl.create(:user) } But here is the error that I keep seeing: NameError: undefined method `user' for nil:NilClass This error traces back to my authenticate_user! method in the controller: def authenticate_user! redirect_to login_path, notice: "You need to sign in or sign up before continuing." if env['warden'].user.nil? end I'd appreciate any guidance that anyone could provide.

• Arrays/Lists and computing hashvalues (VB, C#)

  - by Jeffrey Kern

  I feel bad asking this question but I am currently not able to program and test this as I'm writing this on my cell-phone and not on my dev machine :P (Easy rep points if someone answers! XD ) Anyway, I've had experience with using hashvalues from String objects. E.g., if I have StringA and StringB both equal to "foo", they'll both compute out the same hashvalue, because they're set to equal values. Now what if I have a List, with T being a native data type. If I tried to compute the hashvalue of ListA and ListB, assuming that they'd both be the same size and contain the same information, wouldn't they have equal hashvalues as well? Assuming as sample dataset of 'byte' with a length of 5 {5,2,0,1,3}

• Check whether a string is a valid filename with Qt

  - by ereOn

  Hi, Is there a way with Qt 4.6 to check if a given QString is a valid filename (or directory name) on the current operating system ? I want to check for the name to be valid, not for the file to exist. Examples: // Some valid names test under_score .dotted-name // Some specific names colon:name // valid under UNIX OSes, but not on Windows what? // valid under UNIX OSes, but still not on Windows How would I achieve this ? Is there some Qt built-in function ? I'd like to avoid creating an empty file, but if there is no other reliable way, I would still like to see how to do it in a "clean" way. Many thanks.

• Find out 20th, 30th, nth prime number. (I'm getting 20th but not 30th?) [Python]

  - by gsin

  The question is to find the 1000th prime number. I wrote the following python code for this. The problem is, I get the right answer for the 10th , 20th prime but after that each increment of 10 leaves me one off the mark. I can't catch the bug here :( count=1 #to keep count of prime numbers primes=() #tuple to hold primes candidate=3 #variable to test for primes while count<20: for x in range(2,candidate): if candidate%x==0: candidate=candidate+2 else : pass primes=primes+(candidate,) candidate=candidate+2 count=count+1 print primes print "20th prime is ", primes[-1] In case you're wondering, count is initialised as 1 because I am not testing for 2 as a prime number(I'm starting from 3) and candidate is being incremented by 2 because only odd numbers can be prime numbers. I know there are other ways of solving this problem, such as the prime number theorem but I wanna know what's wrong with this approach. Also if there are any optimisations you have in mind, please suggest. Thank You

• CSS dropdowns on touch-based clients. Are pure CSS dropdowns going to become extinct?

  - by Galen

  My company is starting to move toward adding the iPad as a browser i have to test my work on. This got me thinking... Since touch-based clients don't have a :hover state are pure CSS dropdowns going to go away? Then i thought even if you add some javascript to make the menus popup on click... What happens when the menu item (that expands to another menu) is also a link. How do you tell the difference between a click to see the menu or a click to go to that link?

• Track status of Microsoft TTS output to wav file

  - by user325478

  I'm trying to track the status of my applications TTS output to a wav file. When speaking the text (to the speaker) the expected events (StartStream, Word, EndStream) are fired, however, no events are fired when outputing to a wave file. SpVoice vox = new SpVoice(); vox.Word += VoxWord; // Handle word processed event SpFileStream voxStream = new SpFileStream(); voxStream.Open(@"c:\test.wav", SpeechStreamFileMode.SSFMCreateForWrite, false); vox.AudioOutputStream = voxStream; vox.Speak("Hello World. Please track my status!", SpeechVoiceSpeakFlags.SVSFlagsAsync); Is it possible to asynchronously know the status of TTS output to wav?

• Android insert into sqlite database

  - by Josh

  I know there is probably a simple thing I'm missing, but I've been beating my head against the wall for the past hour or two. I have a database for the Android application I'm currently working on (Android v1.6) and I just want to insert a single record into a database table. My code looks like the following: //Save information to my table sql = "INSERT INTO table1 (field1, field2, field3) " + "VALUES (" + field_one + ", " + field_two + ")"; Log.v("Test Saving", sql); myDataBase.rawQuery(sql, null); the myDataBase variable is a SQLiteDatabase object that can select data fine from another table in the schema. The saving appears to work fine (no errors in LogCat) but when I copy the database from the device and open it in sqlite browser the new record isn't there. I also tried manually running the query in sqlite browser and that works fine. The table schema for table1 is _id, field1, field2, field3. Any help would be greatly appreciated. Thanks!

• StructureMap: Wiring (generic) implementations to an implementation of another type

  - by Jeremy Frey

  If I have an interface: public interface IRepository<T> And an abstract class: public abstract class LinqToSqlRepository<T, TContext> : IRepository<T> where T : class where TContext : DataContext And a whole bunch of implementations of IRepository / LinqToSqlRepository (e.g. AccountRepository, ContactRepository, etc.), what's the best way to to use StructureMap (2.5.3) to generically wire them all up? e.g., I want this code to pass: [Test] public void ShouldWireUpAccountRepositories { var accountRepo = ObjectFactory.GetInstance<IRepository<Account>>(); Assert.IsInstanceOf<AccountRepository>(accountRepo); } Without explicitly writing this: ObjectFactory.Configure(x => x.ForRequestedType<IRepository<Account>>() .TheDefaultIsConcreteType<AccountRepository>()); In the past, we've always created a specific interface on each repository that inherited from the generic one, and used the default scanner to automatically wire all of those instances, but I'd like to be able to ask specifically for an IRepository<Account> without cluttering up the project with additional interfaces / configurations.

• Reading JSON with JQuery
