• Do I have to worry about escaping XML reserved characters before I return a DataContract object from

  - by Brett Widmeier

  Hi, I am pretty inexperienced with WCF. I have a DataContract that implements the IExtensibleDataObject interface. Some of the members of this object are populated from freetext input and could contain XML reserved characters ('', for example). I imagine that I get escaping of these characters for free with WCF, but I have been looking around and could not find anything commenting on this one way or another. Is this the case? I have set my service to log the messages that it sends and receives for viewing in the Trace Viewer. Part of a message that my service returns looks like this: <sInstructions>"></sInstructions> Now, I have a couple questions about this. 1) Is it actually transmitting "&gt; and just showing it in a more readable form in the trace viewer? 2) If it is actually is transmitting ">, is this legal XML?

• Starting a browser from a textbox via Intent - Is http:// required?

  - by VitalyB

  Hi, I have the following code: /** Open a browser on the URL specified in the text box */ private void openBrowser() { Uri uri = Uri.parse(urlText.getText().toString()); Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent); } When I input "http://www.google.com" to the textbox, it works fine. However, when I try something like "www.google.com" it crashes with: No Activity found to handle Intent { act=android.intent.action.VIEW dat=www.google.com } Am I using Uri wrong? Is there a way to extract full address from it? Or am I supposed to write code that adds http manually? e.g, if not starts with http://, add http://. Thanks!

• Radius of multiple latitude/longitude points

  - by zekial

  I have a program that takes as input an array of lat/long points. I need to perform a check on that array to ensure that all of the points are within a certain radius. So, for example, the maximum radius I will allow is 100 miles. Given an array of lat/long (coming from a MySQL database, could be 10 points could be 10000) I need to figure out if they will all fit in a circle with radius of 100 miles. Kinda stumped on how to approach this. Any help would be greatly appreciated.

• How to find the largest square in the number (Java)

  - by Ypsilon IV

  Hello everyone, I want to find the largest square in the number, but I am stuck at some point. I would really appreciate some suggestions. This is what I've done so far: I take the number on the input, factorize into prime numbers, and put the sequence of prime numbers to ArrayList. Numbers are sorted, in a sense, thus the numbers in the sequence are increasing. For example, 996 is 2 2 3 83 1000 is 2 2 2 5 5 5 100000 is 2 2 2 2 2 5 5 5 5 5 My idea now is to count number of occurrences of each elements in the sequence, so if the number of occurrences is divisible by two, then this is the square. In this way, I can get another sequence, where the right most element divisible by two is the largest square. What is the most efficient way to count occurrences in the ArrayList? Or is there any better way to find the largest square? Many thanks in advance!

• php $_POST array empty upon form submission...

  - by Mike D

  Hi folks, I'm baffled on this after much googling. This issue is simple, I have a custom CMS i've built that works perfectly on my dev box (Ubuntu/PHP5+/MySQL5+). I just moved it up to the production box for my client and now all form submissions are showing up as empty $_POST arrays. I found a trick to verify the data is actually being passed using "file_get_contents('php://input');" and the data is showing up fine there -- the $_POST/$_REQUEST arrays are always empty. I've also verified the content-type headers are correct as well via firebug (application/x-www-form-urlencoded; charset=utf-8). This issue is happening regardless of whether a form is submitting via AJAX or a regular form submit. Any help is greatly appreciated!

• Why is $file empty in custom symfony file validator?

  - by codecowboy

  I am setting a custom file validator for a file input field in Symfony 1.4 (Doctrine) $this-setValidator('filename', new sfValidatorFile(array( 'mime_types' = 'web_images', 'path' = sfConfig::get('sf_upload_dir').'/animals', 'validated_file_class' = 'CustomValidatedFile', 'required' =false ))); I then want to override the save method to generate some thumbnails: class CustomValidatedFile extends sfValidatedFile { private $savedFilename; // Override sfValidatedFile's save method public function save($file = null, $fileMode = 0666, $create = true, $dirMode = 0777) { $this-savedFilename = $this-generateFilename(); // This makes sure we use only one savedFilename (it will be the first) if ($this-savedFilename === null ) { $this-savedFilename = $file; } $thumbnail = new sfThumbnail(150,150); $thumbnail-loadFile($this-getTempName()); $thumbnail-save(sfConfig::get('sf_upload_dir').'/thumbnails/thumb_'.$this-savedFilename); // Let the original save method do its magic :) return parent::save($this->savedFilename, $fileMode, $create, $dirMode); } } This fails with the error "The file "" is not readable." This is coming from sfThumbnailPlugin because the value of $file is null. My question is why is $file null?

• Map Reduce job on Amazon: argument for custom jar

  - by zero51

  Hi all, This is one of my first try with Map Reduce on AWS in its Management Console. Hi have uploaded on AWS S3 my runnable jar developed on Hadoop 0.18, and it works on my local machine. As described on documentation, I have passed the S3 paths for input and output as argument of the jar: all right, but the problem is the third argument that is another path (as string) to a file that I need to load while the job is in execution. That file resides on S3 bucket too, but it seems that my jar doesn't recognize the path and I got a FileNotFound Exception while it tries to load it. That is strange because this is a path exactly like the other two... Anyone have any idea? Thank you Luca

• Minimizing Java Thread Context Switching Overhead

  - by binil

  I have a Java application running on Sun 1.6 32-bit VM/Solaris 10 (x86)/Nahelem 8-core(2 threads per core). A specific usecase in the application is to respond to some external message. In my performance test environment, when I prepare and send the response in the same thread that receives the external input, I get about 50 us advantage than when I hand off the message to a separate thread to send the response. I use a ThreadPoolExecutor with a SynchronousQueue to do the handoff. In your experience what is the acceptable delay between scheduling a task to a thread pool and it getting picked up for execution? What ideas had worked for you in the past to try improve this?

• How to get the records using order by and so on

  - by paulrajj

  I have a table categories containing categories id having the records of 1 to 20. when i am doing the search query by using the IN function in mysql i got the results. but i am struggling to get the results using order by. The limit may be vary for every search as this is one of the input value. For example I have tried this query to find out the search results, select * from categories where category in (20,16,12,8) order by rand(), id limit 0,6 this query is executed and the results are in random category_id. the results will be, 8 12 16 20 and following this, another two records must be 8 12 If category_id contains only one record for 8 then, it should follow from 12,16. How can i achieve this ? thanks in advance.

• Does Len function only evaluate numerical results?

• Mutually exclusive regular expressions

  - by CaptnCraig

  If I have a list of regular expressions, is there an easy way to determine that no two of them will both return a match for the same string? That is, the list is valid if and only if for all strings a maximum of one item in the list will match the entire string. It seems like this will be very hard (maybe impossible?) to prove definitively, but I can't seem to find any work on the subject. The reason I ask is that I am working on a tokenizer that accepts regexes, and I would like to ensure only one token at a time can match the head of the input.
