• Unexpected generics behaviour

  - by pronicles

  I found strange generics behaviour. In two words - thing I realy want is to use ComplexObject1 in most general way, and the thing I realy missed is why defined generic type(... extends BuisnessObject) is lost. The discuss thread is also awailable in my blog http://pronicles.blogspot.com/2010/03/unexpected-generics-behaviour.html. public class Test { public interface EntityObject {} public interface SomeInterface {} public class BasicEntity implements EntityObject {} public interface BuisnessObject<E extends EntityObject> { E getEntity(); } public interface ComplexObject1<V extends SomeInterface> extends BusinessObject<BasicEntity> {} public interface ComplexObject2 extends BuisnessObject<BasicEntity> {} public void test(){ ComplexObject1 complexObject1 = null; ComplexObject2 complexObject2 = null; EntityObject entityObject1 = complexObject1.getEntity(); //BasicEntity entityObject1 = complexObject1.getEntity(); wtf incompatible types!!!! BasicEntity basicEntity = complexObject2.getEntity(); } }

• htaccess handler

  - by Steve

  Hi Everyone, I have strange problem that need help. It is about rewrite using apache. Here my .htaccess content file: Options +FollowSymLinks ## This is an example .htaccess-file ## To get everything automatically parsed, the following line is needed #set link auto on ##From now on, every RewriteRule gets recognised. RewriteEngine on RewriteRule captcha(\.html){0,1}$ captcha.php [QSA,L] RewriteCond %{SCRIPT_FILENAME} !-s RewriteCond %{SCRIPT_FILENAME} !-d RewriteCond %{SCRIPT_FILENAME} !-f Rewriterule (.*) handler.php ##You can also change the text before the real link by the following line With this rule, I am hoping that all request except there is exists in file or directory will be directed to my custom handler: handler.php.

• iPhone: fast hash function for storing web images (url) as files (hashed filenames)

  - by Stefan Klumpp

  What is a fast hash function available for the iPhone to hash web urls (images)? I'd like to store the cached web image as a file with a hash as the filename, because I suppose the raw web url could contain strange characters that could cause problems on the file system. The hash function doesn't need to be cryptographic, but it definitely needs to be fast. Example: Input: http://www.calumetphoto.com/files/iccprofiles/icc-test-image.jpg Output: 3573ed9c4d3a5b093355b2d8a1468509 This was done by using MD5(), but since I don't know much about that topic I don't know if it is overkill (- slow).

• IE 8 dialog windows not decompressing files

  - by Mike

  Hi, I've got a website where we have pre-compressed all of our HTML files. In general this works fine, but since IE 8 has come out some people are finding that they can not use some parts of the website. We've used the showModalDialog command to open a dialog window and pointing to one of our pre-compressed files but it displays it just show up as strange characters (ie not decompressed). Now it only happens in the dialog. I'm pretty sure our compression is all fine because the page they are viewing to open the dialog is also compressed. Has anyone else come across this or got any suggestions cuz i'm stumped??? Thanks, Mike

• Loading an OverlayView from XIB -vs- programmatically for use with UIImagePickerController

  - by PLG

  I am currently making a camera app for iPhone and I have a strange phenomenon that I can't figure out. I would appreciate some help understanding. When recreating an overlay view for passing to UIImagePickerController, I have been successfully been able to create the view programmatically. What I haven't been able to do is create the view with/without controller in IB, load it and pass it to the overlay pointer successfully. If I do it via IB, the view is not opaque and obscures the view of the camera completely. I can not figure out why. I was thinking that the normal view pointer might be assigned when loading from XIB and therefore overwrite the camera's view, but I have an example programmatically where view and overlayView are set equal in the controller class. Perhaps the load order is overwriting a pointer? Help would be appreciated... kind regards.

• Are Sphinx & thinking_sphinx really stable? Not indexing Columns

  - by seb

  I'm encountering strange behaviour from thinking_sphinx/sphinx. My define_index block is about 100 lines, so quite a lot of columns i'm indexing. For full-text searching I only need about 10 attributes, for sorting and filtering I have another approximately 50 columns, mostly floats and integers. By filtering I mean using the "with" or "without" options. Searching does not really work consistently. All of a sudden, one attribute fails to filter. Or if I add a new one, it does not work. Only after a lot of tinkering it suddenly starts working. I cannot really reproduce it. Steps I that sometimes lead me to success where: rm -rf db/sphinx change the attribute definition e.g. has some_attribute = has some_attribute, :sortable = true or = has some_attribute, :sortable = true, :as = "some_attribute" restarting the server assigning a new :as name = has some_attribute, :as = "some_attribute_new" (yes, I did rake ts:rebuild or rake ts:in after every step) Does anybody else encounter similar problems?

• Sharepoint Blog Category view - Pagination issue...

  - by hemalshah

  Folks, I am facing a rather strange issue. In my Sharepoint Blog, I am not able to view more than 10 posts when I click on the Category filter page. The page only shows the latest 10 posts and when I click on the pagination for the next 10, it simply says that "There are no posts in this category." I tried searching online and some one had a solution to it too, but that is with the Query String (URL) Filter which is not available in MOSS2007 Standard edition... How can I get around this? Any help would be greatly appreciated...

  - by Nickson

  Am adding an Entity Data Model to an ASP.NET website. When i Add New Item to the website and select ADO.NET Entity Data Model, am asked for the model name and language. I go a head and select Visual Basic as the language, the model is added and the site can compile with out any issues. however, the model it adds a ModelName.Designer.cs source file, instead of a ModelName.Designer.vb source file. am thinking this is strange as its happening with only one of my website. my other sites have .vb designer source file for their Entity Data Models. The site still compiles with out any errors but am afraid some thing is not right. any one experienced this?, is this normal behavior?

• Changing property type in class that implements interface with object type property.

  - by used2could

  I know the title is a bit confusing but bare with me. (I'm up for suggestions on a new title lol) I'm writing a TemplateEngine that will allow me to use my own markup in text based files. I'm wanting to add controls as plugins as the application matures. Currently i've got a structure like the following: interface IControl string Id object Value class Label : IControl string Id string Value class Repeater : IControl string Id List<IControl> Value Now you'll see the strange part right away in the Repeater class with the Value property. I was hoping that having the Value type as object in the interface would allow me the flexibility to expand the controls as i go along. The compiler doesn't like this and for good reason i guess. Does anyone have any suggestions how to accomplish this? Note: Please don't go into suggesting things like use Spark View Engine for templating. There is a reason i'm creating extra work for myself.

• JSF, actionlistener at facelets

  - by asrijaal

  Hi there, I'm using JSF (Mojarra 1.2) with Richfaces (3.3.2) within some facelets which are used as portlets (I'm using the Jboss Portlet Bridge 2.0 here). Now I'm facing something strange: I've got an actionlistener on my <h:commandButton> which is triggered, when the button is clicked but when I simply reload the page, the action is executed everytime I load the page again. This happens only if I already triggered the action before. Is this behaviour normal? I should notice that Spring 2.5 is used to manage my beans, the mentioned beans are session-scope beans, maybe this is a interessting point?!

• Has anyone noticed that a WPF file dialog will pass a click through to the UI when double clicking t

  - by Ben

  I have some buttons on my WPF UI and I also need to choose files from time to time. I kept noticing strange problems where when I double-click an item in the file dialog, a button on the main UI would also get clicked. After experimenting, it seems that if you line up an item in the file dialog with a button behind it on the main UI and double click to select the file, it will single-click the button behind it as well. Has anyone else noticed this, or is it just a freak bug with the way I have my UI laid out?

• Simple Android OpenGL App Lag

  - by Eugene

  Hi, I have an Android OpenGL application which simply draws 2D squares (using 2 triangles) and animates them moving down the screen. I essentially do this by running: glLoadIdentity(), then glTranslatef, and finally glDrawElements all in a for loop. (The for loop is to draw all 10 blocks on the screen for every frame). In every drawFrame, the y-position of the blocks increments for the animation. The problem I'm having is strange. I run the application and the animation is laggy and not smooth. Then I re-run the application and I get a smooth animation. If I run again, I may get a smooth animation, or possibly not. Is my method correct, or is there a better way of doing this animation? Thanks for the help!

• Convert wife/husband/partner to a programmer.

  - by Stefan

  originally posted by Stefan: How many of you have had the thought of educate your partner and invite him/her to the beautiful world of programming? I once started to give my wife lessons twice a week, It was a competition between me and another programmer, we thought it would be nice to have our wives understand why we work as programmers and also have it as a hobby sitting all night long. Maybe we could get our wives to feel the power too? After a couple of months my wife didn't like the idea any more, it was too hard to understand she thought, same for my friends wife. So now we are thinking of some project that would be too fun for our wives to turn down just to get the spirit up again. It would be nice to hand over a project to my wife, "Can you debug this for me, please? There are some strange error on module xxx." :) Maybe I'm crazy, what do you think?

• fileinfo and mime types I've never heard of

  - by Jim

  I'm not a stranger to mime types but this is strange. Normally, a text file would have been considered to be of text/plain mime but now, after implementing fileinfo, this type of file is now considered to be "text/x-pascal". I'm a little concerned because I need to be sure that I get the correct mime types set before allowing users to upload with it. Is there a cheat sheet that will give me all of the "common" mimes as they are interpreted by fileinfo? Sinan provided a link that lists all of the more common mimes. If you look at this list, you will see that a .txt file is of text/plain mime but in my case, a plain-jane text file is interpreted as text/pascal.

  - by RRUZ

  I have found an strange behavior when use the open file dialog in c#. If use this code in Windows XP the current working directory changes to the path of the selected file, however if you run this code in windows 7 the current working directory does not change. private void button1_Click(object sender, EventArgs e) { MessageBox.Show(string.Format("Current Directory {0}",Directory.GetCurrentDirectory()), "My Application",MessageBoxButtons.OK, MessageBoxIcon.Asterisk); DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog and get result. if (result == DialogResult.OK) { } MessageBox.Show(string.Format("Current Directory {0}", Directory.GetCurrentDirectory()), "My Application", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); } Anybody know the reason for this behavior? Why the current directoiry changes in XP and not in windows 7?

• Some unclear PHP syntax

  - by serhio

  I am a PHP beginner and saw on the forum this PHP expression: $regex = <<<'END' / ( [\x00-\x7F] # single-byte sequences 0xxxxxxx | [\xC0-\xDF][\x80-\xBF] # double-byte sequences 110xxxxx 10xxxxxx | [\xE0-\xEF][\x80-\xBF]{2} # triple-byte sequences 1110xxxx 10xxxxxx * 2 | [\xF0-\xF7][\x80-\xBF]{3} # quadruple-byte sequence 11110xxx 10xxxxxx * 3 ) | ( [\x80-\xBF] ) # invalid byte in range 10000000 - 10111111 | ( [\xC0-\xFF] ) # invalid byte in range 11000000 - 11111111 /x END; Is this code correct? What do these strange (for me) constructions like <<<, 'END', /, /x, and END; mean? I recieve: Parse error: syntax error, unexpected T_SL in /home/vhosts/mysite.com/public_html/mypage.php on line X Thanks

• GWT application throws an exception when run on Google Chrome with compiler output style set to 'OBF

  - by Elifarley

  I'd like to know if you guys have faced the same problem I'm facing, and how you are dealing with it. Sometimes, a small and harmless change in a Java class ensues strange errors at runtime. These errors only happen if BOTH conditions below are true: 2) the application is run on Google Chrome, and 1) the GWT JavaScript compiler output style is set to 'OBF'. So, running the application on Firefox or IE always works. Running with the output style set to 'pretty' or 'detailed' always works, even on Google Chrome. Here's an example of error message that I got: "((TypeError): Property 'top' of object [object DOMWindow] is not a function stack" And here's what I have: - GWT 1.5.3 - GXT 1.2.4 - Google Chrome 4 and 5 - Windows XP In order to get rid of this Heisenbug, I have to either deploy my application without obfuscation or endure a time-consuming trial-and-error process in which I re-implement the change in slightly different ways and re-run the application, until the GWT compiler is happy with my code. Would you have a better idea on how to avoid this?

• javafx 2, CSS and focus disappearing

  - by AgostinoX

  I've created a very simple CSS that styles two buttons. To the first has just been added a padding. To the second has been set the -fx-background-color, but the value is taken from caspian.css, that is the value it should have before it had been set. .first-style { -fx-padding: 20 5 1 5; } .second-style { -fx-background-color: -fx-shadow-highlight-color, -fx-outer-border, -fx-inner-border, -fx-body-color; } At this point i experience a strange behavior: the focus decoration stops working, and the second button doesn't get its blue border when focused. What's happening?

• "No context-sensitive help installed" , "user32.dll" and "uxtheme.dll" AV errors on Delphi with no reason

  - by Javid

  This is very strange guys. I wrote a simple application. When I make my commands executed fast by moving mouse (event is on mouse move), I experience the following errors if I run my application without debugger (if I do, application just hangs and nothing happens): 1- "No context-sensitive help installed" however i haven't used help in my app. 2- Access violation errors from "uxtheme.dll" and "user32.dll" libraries! well, i think these errors happen when Windows Messages are sent quickly one after another. I came across these errors a while ago in a huge application. In both application I used SendMessage command, but what am i doing wrong? I'm now using Delphi 2010 Has anyone ever experienced this?!

• iOS localization inconsistency

  - by Joe Völker

  I'm localizing an iPhone app for the first time. I've put all my strings into a Localizable.strings file, accessing them via NSLocalizedString from within my code. Works fine. Next, I have a file called info.html that contains the flesh of a UIWebView that I use as an About box. I've put it in the language folders (en.lproj and de.lproj), and added them to my Resources in Xcode. Now, in Simulator, both the Strings, and the html file display in the appropriate language. However, on the device, the Strings appear localized while the html file remains untranslated. This is a strange inconsistency between Simulator and Device! Anybody know of a workaround? (...other than defying the localization system, and using NSLocalizedString to call de_info.html, en_info.html etc. by hand.)

• Error calling webservice from JQuery

  - by Robban

  I have a strange problem when I'm trying to call a simple webservice method from Jquery. Locally it works fine, but on my test-server it does not. The jquery request looks like this (only showing the actual request and not the rest of the method): $.ajax({ type: "POST", url: "/Service/Service.asmx/AddTab", data: "tab=" + element.innerHTML, success: function(msg) { alert('success'); } }); When I run this locally from the test-server it works fine, which has me wondering if it could be some setting that I've missed in the IIS. If I navigate to the .asmx file and click the AddTab method I get a list of SOAP 1.1 and SOAP 1.2 XML, but not the HTTP POST request. If I navigate to it locally I get all three (SOAP 1.1, SOAP 1.2 and HTTP Post) The service is set up as follows: [WebService(Namespace = "mynamespace")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] [ScriptService()] public class Service : System.Web.Services.WebService { [WebMethod(EnableSession=true)] [ScriptMethod()] public void AddTab(string tab) { //Some code to add a tab which evidently works locally... } } Anyone have a clue what I'm missing here?

• Resharper Autocomplete Issue

  - by Gene

  Hi All, I've been using resharper with the resharper automplete off (just find VS better for my purposes currently), but despite trying every setting I've tried, whenever I use a resharper template (such as tab-completing an if - if block), the resharper autocomplete dialog comes up in addition to the visual studio dialog (thus if they don't autocomplete to the same thing, or I accidentally hit enter, whatever I originally typed is replaced with the wrong resharper suggestion, effectively highlighting why I turned it off in the first place). A. Has anyone every seen this before? (I ask since I might have turned on/off a number of settings in a strange/incompatible way and perhaps a clean install might clear it up.) B. Any suggestions? :) (Visual Studio 08 SP1, Resharper 4.5.2 - only other tools installed are DevExpress, but they have long since been disabled) Thanks all!

• wp_redirect acting weird. requires die() afterward?

  - by Joseph Carrington

  I am writing a wordpress plugin that redirects the user. for some reason, wp_redirect does not work as think it should, namely: it seems not to redirect the user at all, unless I put a die command in directly after. here is some code: switch($_GET['wp_favorites_tax']) { case 'post_tag': wp_redirect(add_query_arg('tag', $_GET['wp_favorites_term'], get_bloginfo('url'))); die(); break; case 'category': wp_redirect(add_query_arg('cat', $_GET['wp_favorites_term'], get_bloginfo('url'))); die(); break; default: wp_redirect(get_bloginfo('url')); die(); } It seems really strange to me that I should have to tell my script to die so that the redirect can work. I have also tried a basic header("Location: $location); to similar ends, ie: it still requires the die() in order to work. really perplexing me. Thanks.

• Timer in windows service

  - by Markus

  Hi. I have an issue with System.Threading.Timer. I am scheduling some actions using a time in a windows service. The timer starts executing the callback after a specified dueTime period. The windows service starts up after reboot automatically. However, I have observed a strange thing after a system reboot- the callback method starts executing itself 3 or 4 minutes before the specified period. What might be the reason for such behavior? Here is the sample code: TimeSpan timeToWait = this.StartTime - DateTime.Now; Int64 msToSleep = (Int64)Math.Round(timeToWait.TotalMilliseconds); _timer = new Timer(callback_method, null, msToSleep, MinutesScheduledInterval * 60000); where _timer is a member variable, StartTime - the time when the timer should first fire.
