  • How to return proper 404 for google while providing user friendly content to the user?

    - by Marek
    I am bouncing between posting this here and on Superuser. Please excuse me if you feel this does not belong here. I am observing the behavior described here - Googlebot is requesting random urls on my site, like aecgeqfx.html or sutwjemebk.html. I am sure that I am not linking these urls from anywhere on my site. I suspect this may be google probing how we handle non existent content - to cite from an answer to the linked question: [google is requesting random urls to] see if your site correctly handles non-existent files (by returning a 404 response header) We have a custom page for nonexistent content - a styled page saying "Content not found, if you believe you got here by error, please contact us", with a few internal links, served (naturally) with a 200 OK. The URL is served directly (no redirection to a single url). I am afraid this may discriminate the site at google - they may not interpret the user friendly page as a 404 - not found and may think we are trying to fake something and provide duplicate content. How should I proceed to ensure that google will not think the site is bogus while providing user friendly message to users in case they click on dead links by accident?

  • How do I prevent a C# method from executing using an attribute validator?

    - by Boydski
    I'd like to create an attribute-based validator that goes a few steps beyond what I've seen in examples. It'll basically prevent methods or other functionality from executing. Please be aware that I'm having to use AzMan since I have no availability to Active Directory in this scenario. Here's some pseudo code of what what I'm looking for: // Attribute validator class AttributeUsage is arbitrary at this point and may include other items [AttributeUsage( AttributeTargets.Method | AttributeTargets.Property, AllowMultiple = true, Inherited = true )] public class PermissionsValidatorAttribute : Attribute { public PermissionsValidatorAttribute(PermissionEnumeration permission){...} public bool UserCanCreateAndEdit(){...} public bool UserCanDelete(){...} public bool UserCanUpload(){...} } Here's a sample of a class/member that'll be decorated. The method will not be executed at all if the PermissionValidator.UserCanDelete() doesn't return true from wherever it's executed: public class DoStuffNeedingPermissions { [PermissionValidator(PermissionEnumeration.MustHaveDeletePermission)] public void DeleteSomething(){...} } I know this is a simple, incomplete example. But you should get the gist of what I'm needing. Make the assumption that DeleteSomething() already exists and I'm preferring to NOT modify the code within the method at all. I'm currently looking at things like the Validation Application Block and am messing with custom attribute POC's. But I'd love to hear opinions with code samples from everyone out there. I'm also certainly not opposed to other methods of accomplishing the same thing such as extension methods or whatever may work to accomplish the same thing. Please remember I'm making the attempt to minimize changes to existing DoStuffNeedingPermissions code. Thanks everyone!

  • NAnt errors when generating assembly info after project is upgraded to VS2010

    - by Grant Palin
    I have a project I recently upgraded to VS2010 - the project/solution files are updated, but I'm still targeting .NET 3.5. Until now, my standard NAnt build script has not given me any trouble. However, it appears that after updating the project, and updating the NAnt config to be aware of the new tooling, I am now receiving an error when autogenerating assembly information, which fails the build. The relevant build task is below: <asminfo output="${dir.src}\${file.commonAssemblyInfo}" language="${project.codeLanguage}"> <imports> <import namespace="System.Reflection" /> </imports> <attributes> <attribute type="AssemblyVersionAttribute" value="${project.fullversion}" /> <attribute type="AssemblyFileVersionAttribute" value="${project.fullversion}" /> <attribute type="AssemblyInformationalVersionAttribute" value="${project.fullversion}" /> <attribute type="AssemblyCopyrightAttribute" value="${assembly.copyright}" /> <attribute type="AssemblyCompanyAttribute" value="${assembly.company}" /> <attribute type="AssemblyConfigurationAttribute" value="${project.config}" /> <attribute type="AssemblyTrademarkAttribute" value="${assembly.trademark}" /> <attribute type="AssemblyProductAttribute" value="${assembly.product}" /> </attributes> </asminfo> The error is highlighted for the first line of the asminfo task. It reads: AssemblyInfo file 'C:\Users\Grant\Projects\VisualStudio\Checklist\src\CommonAssemblyInfo.cs' could not be generated. This method implicitly uses CAS policy, which has been obsoleted by the .NET Framework. In order to enable CAS policy for compatibility reasons, please use the NetFx40_LegacySecurityPolicy configuration switch. Please see http://go.microsoft.com/fwlink/?LinkID=155570 for more information. I've gathered so far that this is something new to .NET 4. Has anyone had to address this error before? Does anyone know what it is about asminfo that may be triggering the error?

  • Filling SWT table object using a separated thread class ...

    - by erlord
    Hi all I've got a code snippet by the swt team that does exactly what I need. However, there is a part I want to separate into another class, in particular, the whole inline stuff. In response to my former question, it has been suggested that Callable should be used in order to implement threaded objects. It is suggested to make use of an implementation of runnable or better callable, since I do need some kind of return. However, I don't get it. My problems are: In the original code, within the inline implementation of the method run, some of the parents objects are called. How would I do this when the thread is separated? Pass the object via the C'tor's parameter? In the original code, another runnable object is nested within the runnable implementation. What is it good for? How to implement this when having separated the code? Furthermore, this nested runnable again calls objects created by the main method. Please, have mercy with me, but I am still quite a beginner and my brain is near collapsing :-( All I want is to separate all the threaded stuff into another class and make the program do just the same thing as it already does. Help please! Again thank you very much in advance for any useful suggestions, hints, examples etc... Regs Me

    - by Shrewd Demon
    hi i have an application wherein i am accessing the Session object in the CommonCode.cs file that resides in the App_Code folder. But when the session object is accessed the application throws me an error: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive.

  • Disturbing or politically incorrect classes

    - by Jonas B
    Please don't take this seriously! - Community wikied Satire is always fun. Try to come up with the most shocking, disturbing or politically incorrect class you can think of. (But please no racism or anything seriously offensive or anything that can't be interpeted as satire). I'll go first with my example: public class Person { public bool Female; public Person(bool female) { Female = female; } public static bool operator <(Person j1, Person j2) { if (j1.Female && !j2.Female) return true; else return false; } public static bool operator >(Person j1, Person j2) { if (!j1.Female && j2.Female) return true; else return false; } public static bool operator <=(Person j1, Person j2) { if ((j1.Female == j2.Female) || (j1.Female && !j2.Female)) return true; else return false; } public static bool operator >=(Person j1, Person j2) { if ((j1.Female == j2.Female) || (!j1.Female && j2.Female)) return true; else return false; } }

  • extern and global in c

    - by JPro
    Can anyone please tell me is there any special requirement to use either EXTERN or GLOBAL variables in a C program? I do not see any difference in a program like below, if I change from gloabl to extern. #include <stdio.h> #include <stdlib.h> int myGlobalvar = 10; int main(int argc, char *argv[]) { int myFunc(int); int i; i = 12; myGlobalvar = 100; printf("Value of myGlobalvar is %d , i = %d\n", myGlobalvar, i); i = myFunc(10); printf("Value of passed value : %d\n",i); printf("again Value of myGlobalvar is %d , i = %d\n", myGlobalvar, i); system("PAUSE"); return 0; } int myFunc(int i) { i = 20 + 1000; //extern int myGlobalvar; myGlobalvar = 20000; // printf("Value of passed value : %d",i); return i; } If uncomment extern int myGlobalvar, the value does not change. Is there any correct difference between both? Can anyone please correct me?

  • Re-tweets and replies with JTwitter

    - by Samuh
    I have not used Twitter enough to become familiar with its terminology or the way it works, so please help me in understanding the problem I have at hand. I am getting last 20 status updates posted by some Twitter user via RSS feed, the feed XML is parsed and the statuses are displayed in a ListView. Which means that I have the original tweet in a String variable(row of ListView). When I click a ListView item, I get the option of "Re-tweeting" and "post reply". As, I understand it, when re-tweeting I will have to just update my *status* as: RT @orig-poster <original tweet> and when posting a reply I will have to just update my status as: @orig-poster <my tweet> I skimmed through the JavaDocs of the Jwitter library(Twitter class) and found a setStatus(String) method. I dont think I will have to make use of retweet() or reply() functions of the Twitter class in JTwitter library. Is my understanding correct? Please correct me if I am wrong here or missing anything. Thanks!

  • How to extract a 2x2 submatrix from a bigger matrix

    - by ZaZu
    Hello, I am a very basic user and do not know much about commands used in C, so please bear with me...I cant use very complicated codes. I have some knowledge in the stdio.h and ctype.h library, but thats about it. I have a matrix in a txt file and I want to load the matrix based on my input of number of rows and columns For example, I have a 5 by 5 matrix in the file. I want to extract a specific 2 by 2 submatrix, how can I do that ? I created a nested loop using : FILE *sample sample=fopen("randomfile.txt","r"); for(i=0;i<rows;i++){ for(j=0;j<cols;j++){ fscanf(sample,"%f",&matrix[i][j]); } fscanf(sample,"\n",&matrix[i][j]); } fclose(sample); Sadly the code does not work .. If I have this matrix : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 3.00 4.00 23.00 5.00 2.00 352.00 6.00 And inputting 3 for row and 3 for column, I get : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 Not only this isnt a 2 by 2 submatrix, but even if I wanted the first 3 rows and first 3 columns, its not printing it correctly.... I need to start at row 3 and col 3, then take the 2 by 2 submatrix ! I should have ended up with : 4.00 23.00 352.00 6.00 I heard that I can use fgets and sscanf to accomplish this. Here is my trial code : fgets(garbage,1,fin); sscanf(garbage,"\n"); But this doesnt work either :( What am I doing wrong ? Please help. Thanks !

  • Calculate an Internet (aka IP, aka RFC791) checksum in C#

    - by Pat
    Interestingly, I can find implementations for the Internet Checksum in almost every language except C#. Does anyone have an implementation to share? Remember, the internet protocol specifies that: "The checksum field is the 16 bit one's complement of the one's complement sum of all 16 bit words in the header. For purposes of computing the checksum, the value of the checksum field is zero." More explanation can be found from Dr. Math. There are some efficiency pointers available, but that's not really a large concern for me at this point. Please include your tests! (Edit: Valid comment regarding testing someone else's code - but I am going off of the protocol and don't have test vectors of my own and would rather unit test it than put into production to see if it matches what is currently being used! ;-) Edit: Here are some unit tests that I came up with. They test an extension method which iterates through the entire byte collection. Please comment if you find fault in the tests. [TestMethod()] public void InternetChecksum_SimplestValidValue_ShouldMatch() { IEnumerable<byte> value = new byte[1]; // should work for any-length array of zeros ushort expected = 0xFFFF; ushort actual = value.InternetChecksum(); Assert.AreEqual(expected, actual); } [TestMethod()] public void InternetChecksum_ValidSingleByteExtreme_ShouldMatch() { IEnumerable<byte> value = new byte[]{0xFF}; ushort expected = 0xFF; ushort actual = value.InternetChecksum(); Assert.AreEqual(expected, actual); } [TestMethod()] public void InternetChecksum_ValidMultiByteExtrema_ShouldMatch() { IEnumerable<byte> value = new byte[] { 0x00, 0xFF }; ushort expected = 0xFF00; ushort actual = value.InternetChecksum(); Assert.AreEqual(expected, actual); }

  • MySQL INJECTION Solution...

    - by Val
    I have been bothered for so long by the MySQL injections and was thinking of a way to eliminate this problem all together. I have came up with something below hope that many people will find this useful. The only Draw back I can think of this is the partial search: Jo =returns "John" by using the like %% statement. Here is a php solution: <?php function safeQ(){ $search= array('delete','select');//and every keyword... $replace= array(base64_encode('delete'),base64_encode('select')); foreach($_REQUEST as $k=>$v){ str_replace($search, $replace, $v); } } foo(); function html($str){ $search= array(base64_encode('delete'),base64_encode('select')); $replace= array('delete','select');//and every keyword... str_replace($search, $replace, $str); } //example 1 ... ... $result = mysql_fetch_array($query); echo html($result[0]['field_name']); //example 2 $select = 'SELECT * FROM safeQ($_GET['query']) '; //example 3 $insert = 'INSERT INTO .... value(safeQ($_GET['query']))'; ?> I know, I know that you still could inject using 1=1 or any other type of injections... but this I think could solve half of your problem so the right mysql query is executed. So my question is if anyone can find any draw backs on this then please feel free to comment here. PLEASE GIVE AN ANSWER only if you think that this is a very useful solution and no major drawbacks are found OR you think is a bad idea all together...

  • How can I create "glass" effect on my own UIViews?

    - by lindes
    Hi there, I'm working on an iPhone app that has some non-rectangular UI elements. Currently, I'm subclassing UIView, and in drawRect I'm using a CGPathRef to draw black border and a color-filled interior. I'd like to make these items look more like "buttons", though, so I'd like to have some of the same sort of "glass effects" that are used on e.g. the icons for an iPhone app (when you don't set UIPrerenderedIcon to true), or in other buttons. I hunted around, and found this, which seems to be close to what I need: http://stackoverflow.com/questions/422066/gradients-on-uiview-and-uilabels-on-iphone But I'm having difficulty figuring out how to clip the gradient to my shape. It seems like the mask property on the view would be the right place to go, which seems like it would call for me to create a new CALayer object, with the clipping somehow applied to it. I'm hoping there's some nice convenience function for doing this, though if I need to write something more complicated, that's OK, too. I'm just having difficulty figuring out how to apply the path as a mask. I'm unsure if I need to create a new drawing context and draw the path into it? And then use CGContextClip? I think I've got a lot of the right pieces figured out, I'm just having difficulty understanding how to assemble them. Could someone please point me in the right direction? (I'm happy to read more in the docs, just point me in the right direction, please.)

  • No transperancy in Bitmap loading from MemoryStream

    - by Jogi Joseph George
    Please see the C# code. When i am writing a Bitmap to a file and read from the file, i am getting the transperancy correctly. using (Bitmap bmp = new Bitmap(2, 2)) { Color col = Color.FromArgb(1, 2, 3, 4); bmp.SetPixel(0, 0, col); bmp.Save("J.bmp"); } using (Bitmap bmp = new Bitmap("J.bmp")) { Color col = bmp.GetPixel(0, 0); // ------------------------------ // Here col.A is 1. This is right. // ------------------------------ } But if I write the Bitmap to a MemoryStream and read from that MemoryStream, the transperancy has been removed. All Alpha values become 255. MemoryStream ms = new MemoryStream(); using (Bitmap bmp = new Bitmap(2, 2)) { Color col = Color.FromArgb(1, 2, 3, 4); bmp.SetPixel(0, 0, col); bmp.Save(ms, ImageFormat.Bmp); } using (Bitmap bmp = new Bitmap(ms)) { Color col = bmp.GetPixel(0, 0); // ------------------------------ // But here col.A is 255. Why? i am expecting 1 here. // ------------------------------ } I wish to save the Bitmap to a MemoryStream and read it back with transperancy. Could you please help me?

    - by Peeyush
    I want to use Festival TTS with my C++ programme. So i have downloaded all files form http://www.cstr.ed.ac.uk/downloads/festival/2.0.95/ then i start reading manual(http://www.cstr.ed.ac.uk/projects/festival/manual/festival_28.html) for C++ API but in manual they says that: In order to use Festival you must include festival/src/include/festival.h' which in turn will include the necessary other include files infestival/src/include' and speech_tools/include' you should ensure these are included in the include path for you your program. Also you will need to link your program withfestival/src/lib/libFestival.a', speech_tools/lib/libestools.a',speech_tools/lib/libestbase.a' and `speech_tools/lib/libeststring.a' as well as any other optional libraries such as net audio. " I am using UBUNTU 10.04(festival package is by default installed and i can use it form terminal by festival command) and GCC 4.4.3 but the problem is that i am new to GCC and i am not understanding which files i have to include in order to run my C++ code and i also don't know how to link libraries with my c++ code. So please tell me exactly which files i have to include and how to link with libraries if anyone already use festival tts with c++ then please post your code Thanks

  • Rails: Multi-Step New User Signup Form (FSM?)

    - by neezer
    I've read the "Create Multi-Step Wizard" in Advanced Rails Recipes. I've also read and re-read the documentation for the updated FSM I'm using called Workflow, and looked here and here. The Advanced Rails Recipe focuses on records (quizzes) that already exist, and doesn't cover creating new ones. The Workflow docs don't cover any code for controllers or views, so I've no idea what to do with all this model magic, and the last two links barely touch on implementation either. From the aforementioned resources, I have a good understanding of what a FSM in Rails is and how to play with it in the console or IRB, but I've got very little direction or understanding how to implement one into my Rails app. What I would like is this: a simple, multi-step user signup process. Step 1: User enters in their critical details (with validations). Step 2: User enters in their search criteria, for their profile (with validations). Step 3: User agrees to the Terms of Service (with validations). Step 4: User is greeted by a confirmation page, including a link that takes them to their newly created account. I'd also like full navigation between the steps and full capture (saves to the database) with each transition. Can someone please give me a clear implementation of something similar to this? I would LOVE an example app that includes a multi-step signup process where I can look at the code (FULL source code--models AND controllers and views) under the hood, but I've been unable to find anything like that. Any guidance would be appreciated! EDIT: Please help make this a Railscast! Ryan B. (a.k.a. Superman), if you're reading this, we need you! http://feedback.railscasts.com/forums/77-episode-suggestions/suggestions/35553-multi-step-forms-and-wizards

  • ipad tabbar rotation

    - by MaKo
    hi, please help with this noob questions but really making me go crazy if I create a project from scratch (using windows based app) for the ipad, and add a tabbar , with firstviewController, and secondviewController, it works fine, starts in landscape mode, but in info.plist I set it to Landscape(left home button), but really in simulator starts with the button on the right side! in the FirstViewController.m (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight) return YES; else { return NO; }} so it starts in landscape, and rotates as the simulator rotates, but if I create a template app for iphone tabbar, set the info.plist Initial interface orientation Landscape (left home button) and add the code above, IT DOESNT WORK!!! simulator starts with button at left but tab bar on the side, same problem that I had with an app that Im porting from iphone to ipad, (landscape intended) I get to the landscape start mode, but the tab bar remains on the side! also the only way to make the old ported app to show the simulator on the side was with UIInterfaceOrientation UIIntefaceOrientationLandscapeLeft (didnt work with Initial interface orientation), does not let me choose the value for the key, but it shows the simulator on landscape,, so,, what can I do please to show the tab bar on landscape mode??? the tabbar from scratch was made to see if the code will work , but it didnt?? why does it work in the tab bar made from windows app and not tab bar app? I just want the tab bar to show in landscape ahhh, thanks

  • Using ScriptingBridge framework for communicating with Entourage

    - by Subramanian Ganapathy
    Hi, The motivation for my question is the following doc, which describes how mail.app could be integrated using ScriptingBridge: http://developer.apple.com/mac/library/samplecode/SBSendEmail/Introduction/Intro.html I tried to apply a similar technique with Entourage as well but could not get any results so far. I understand that using AppleScript would help me solve my problem and mactech.com has extensive documentation for doing so. But i find this ScriptingBridge technique elegant and want to figure why it is not working for me with Entourage. The biggest problem seems to be my inability to create Scripting classes based on their names as it happens in Mail because Entourage has a different interface than Mail as their headers indicate. Could someone please tell me what I am missing or provide any sort of hint on why this wont work? I am also adding sample code ` MicrosoftEntourageApplication * mail = [SBApplication applicationWithBundleIdentifier:@"com.Microsoft.Entourage"]; MicrosoftEntourageOutgoingEmailMessage * emailMessage = [[[mail classForScriptingClass:@"outgoing message"] alloc] initWithProperties: [NSDictionary dictionaryWithObjectsAndKeys: @"my sample subject", @"subject", @"my sample body", @"content", nil]]; //then i create a set of recipients and try to use "to recipient" as the string scripting class id, but MicrosoftEntourageRecipient is returned as nil MicrosoftEntourageRecipient * theRecipient = [[[mail classForScriptingClass:@"to recipient"] alloc] initWithProperties: [NSDictionary dictionaryWithObjectsAndKeys: @"[email protected]", @"address", nil]]; ` I am trying to make the simple thing work, I am not even concentrating on the task I am supposed to do now. I am a Cocoa beginner( and willing to learn ), please excuse an syntactic naivetes and do point them out in the sample code, in addition to answering my question. Best Regards, Subramanian

But, one thing that i don't understand is that why should i use them ? Can't i simply check directly against my database of users? and once they successfully login to the site, i store some variable in session as a flag. And probably check that session variable on all restricted pages (I mean keep a filter for restricted resources url pattern).If the flag doesn't exist simply redirect the user to login page. Is this approach correct?Does this approch sound correct? If yes, then why did all this JAAS and jdbcRealm came into existence? Secondly, I am trying to completely implement SAS(Software as service) in my web application, meaning everything is done through web services.If i use webservices, is it possible to use jdbcRealm? If not, then is it possible to use JAAS? If yes, then please show me some example which uses mySql as a database and then authenticates and authorizes. I even heard about Spring Security. But, i am confused about that too in the sense that how do i use webservice with Spring Security. Please help me. I am really very confused. I read sun's tutorials but they only keep talking about theories. For programmers to understand a simple concept, they show a 100 page theory first before they finally come to one example.

I am still not clear what should i start with 1)My main is build website in Java because someone told me that there are some machine learning or AI libraries available in java which i can use in java. so i decided to use that as it can reduce my work. Now i don't know java at all some people say following are used to build websites like 1)Servelts alone can build webiste 2)JSP alone can also build webiste 3)Struts 4)Spring with Hibernate 5)SEAM 6)JEE also for webistes Now guys i am confused where should i start from. Where does core JAVA fits in here. i was thinking of perhaps learning python as i know i have to learn Python only not its variations SO please guide me one thing which can solve my basic purpose of using ready made libraries of AI If i can do that with JSP then i will start with that. But i need to learn all of them then its better if can start learning python. I have 5 months to finish webiste. I really don't know why there are many braches of java for doing one thing Please help me.

  • Timeout error occurred trying to start MySQL Daemon. CentOS 5

    - by epema
    I ran into troubles with MySQL on my CentOS. I had some problems and backed up my database and removed mysql with all dependencies. After that I ran reinstalled: yum groupinstall "MySQL Database" Installed without errors. Running the mysql daemon: service mysqld start Timeout error occurred trying to start MySQL Daemon. Starting MySQL: [FAILED] I also ran # /usr/bin/mysql_install_db --user=mysql Installing MySQL system tables... 120112 1:49:44 [ERROR] Error message file '/usr/share/mysql/english/errmsg.sys' had only 480 error messages, but it should contain at least 481 error messages. Check that the above file is the right version for this program! 120112 1:49:44 [ERROR] Aborting Installation of system tables failed! Examine the logs in /var/lib/mysql for more information. You can try to start the mysqld daemon with: /usr/libexec/mysqld --skip-grant & and use the command line tool /usr/bin/mysql to connect to the mysql database and look at the grant tables: shell> /usr/bin/mysql -u root mysql mysql> show tables Try 'mysqld --help' if you have problems with paths. Using --log gives you a log in /var/lib/mysql that may be helpful. The latest information about MySQL is available on the web at http://www.mysql.com Please consult the MySQL manual section: 'Problems running mysql_install_db', and the manual section that describes problems on your OS. Another information source is the MySQL email archive. Please check all of the above before mailing us! And if you do mail us, you MUST use the /usr/bin/mysqlbug script! Checking the logs: less /var/log/mysqld.log Log file is empty. I don't even know how to debug it and not sure what to do. Any recommendations? Thank you
