• Deserialising Json to derived types in Asp.Net Web API

  - by IoChaos

  I'm calling a method of my WebAPI sending a json that I would like to match (or bind) with a model. In the controller I have a method like: public Result Post([ModelBinder(typeof(CustomModelBinder))]MyClass model); 'MyClass', wich is given as a parameter is an abstract class. I would like that at, depending of the type of json passed, the correct inherited class is instantiated. To achieve it, I'm trying to implement a custom binder. The problem is that (I don't know if it's very basic but I can't find anything) I don't know how to retrieve the raw Json (or better, some kind of serialization) that comes in the request. I see: actionContext.Request.Content But all methods are exposed as async. I don't know who this fits with passing the generate model to the controller method... Thanks a lot!

• How to store Hierarchical K-Means tree for a large number of images, using Opencv?

  - by AquaAsh

  I am trying to make a program that will find similar images from a dataset of images. The steps are 1)extract SURF descriptors for all images 2)store the descriptors 3)Apply knn on the stored descriptors 4)Match the stored descriptors to the query image descriptor using KNN Now each images SURF descriptor will be stored as Hierarchical k means tree, now do I store each tree as a separate file or is it possible to build some sort of single tree with all the images descriptors and updated as images are added to dataset. This is the paper I am basing the program on www.ijest.info/docs/IJEST10-02-03-13.pdf.

• mysql left join

  - by user1019538

  I have two table one is index and another is the price structure as under table : index : column : trandate ,indexcode Table : price : Column: trandate,symbol,price i want to know the missing price. I issue the query select i.trandate,i.indexcode,p.trandate,p.price from index i left join price p on i.trandate = p.trandate where p.symbol='ABC' and indexcode="New" the above query does not show the null date even though various price in missing in price table. Only reason i understand is that the index table does not have the symbol field that's why...but as per theory if you want to show all the rows of one table and only the match value of another table then use the left or right join query...please anybody can help

• Magento - Mage::getModel not working on remote server

  - by Diego

  I'm struggling with an issue for which I can't find an explanation. I have two development environments that I use for my projects. I created a simple module for Magento and I tested it on one environment. After overcoming all Magento's complications, the module works as expected. This is on XAMPP. I then copied the module to the development Linux environment, on a hosted server, and it crashes miserably. I did some debugging, and I found out that a call to Mage::getModel() returns bool(false) instead of the instance of the Model I requested. I double checked all files and directories, and they match. Database is not involved (not from my side, at least, I don't need tables) and both environments have only me as a User, with Admin permissions. Any suggestion on where should I start looking is welcome, thanks.

• Efficient way to combine results of two database queries.

  - by ensnare

  I have two tables on different servers, and I'd like some help finding an efficient way to combine and match the datasets. Here's an example: From server 1, which holds our stories, I perform a query like: query = """SELECT author_id, title, text FROM stories ORDER BY timestamp_created DESC LIMIT 10 """ results = DB.getAll(query) for i in range(len(results)): #Build a string of author_ids, e.g. '1314,4134,2624,2342' But, I'd like to fetch some info about each author_id from server 2: query = """SELECT id, avatar_url FROM members WHERE id IN (%s) """ values = (uid_list) results = DB.getAll(query, values) Now I need some way to combine these two queries so I have a dict that has the story as well as avatar_url and member_id. If this data were on one server, it would be a simple join that would look like: SELECT * FROM members, stories WHERE members.id = stories.author_id But since we store the data on multiple servers, this is not possible. What is the most efficient way to do this? Thanks.

• Why doesn't Python's `re.split()` split on zero-length matches?

  - by Tim Pietzcker

  One particular quirk of the (otherwise quite powerful) re module in Python is that re.split() will never split a string on a zero-length match, for example if I want to split a string along word boundaries: >>> re.split(r"\s+|\b", "Split along words, preserve punctuation!") ['Split', 'along', 'words,', 'preserve', 'punctuation!'] instead of ['', 'Split', 'along', 'words', ',', 'preserve', 'punctuation', '!'] Why does it have this limitation? Is it by design? Do other regex flavors behave like this?

• How to get attributes values separately for each container present on the webpage in jquery ?

  - by Rachel

  This question is in continuation to How to get attributes of container in jquer, I have different containers on my webpage and all of them have <div id = "some values"> now how can I get attributes values separately for each component ? Is there any way I can know which attribute id belong to which container div ? Currently I am using : var id = $( '.promotion' ).attr( 'id' ); But if I have multiple promotional components on page and all have same div attribute as id than how can I relate that this particular attribute id belonged to this specific container ? Update: I am having a function which is called for each container present on the page and so if I am using above mentioned code than will it not always return me the first match for id in the div and would never go to other divs and so I will always get same value for id which is for the first container ? If so than what is the work around for this ? Hope this question is clear.

• Is there any way to prevent the display of unmatched xml tags using xslt?

  - by StevenWilkins

  Here is a contrived example of an xml document. In my real world case, the xml is fairly complex with multiple nested levels. <alphabet> <a>A</a> <b>B</b> <c>C</c> ... and so on </alphabet> Using xslt, I want to transform the document so that only the vowels are printed. In my real world case, we're using empty template match tags to block the display. But that's too verbose for my liking.

• How to code an efficient blacklist filter function in php?

  - by achairapart

  So, I have three arrays like this: [items] => Array ( [0] => Array ( [id] => someid [title] => sometitle [author] => someauthor ... ) ... ) and also a string with comma separated words to blacklist: $blacklist = "some,words,to,blacklist"; Now I need to match these words with (as they can be one of) id, title, author and show results accordingly. I was thinking of a function like this: $pattern = '('.strtr($blacklist, ",", "|").')'; // should return (some|words|etc) foreach ($items as $item) { if ( !preg_match($pattern,$item['id']) || !preg_match($pattern,$item['title']) || !preg_match($pattern,$item['author']) ) { // show item } } and I wonder if this is the most efficient way to filter the arrays or I should use something with strpos() or filter_var with FILTER_VALIDATE_REGEXP ... Note that this function is repeated per 3 arrays. However, each array will not contain more than 50 items.

• Is it possible to write a Java printf statement that prints the statement itself?

  - by polygenelubricants

  Is it possible to have a Java printf statement, whose output is the statement itself? Some snippet to illustrate: // attempt #1 public class Main { public static void main(String[] args) { System.out.printf("something"); } } This prints something. So the output of attempt #1 is not quite exactly the printf statement in attempt #1. We can try something like this: // attempt #2 public class Main { public static void main(String[] args) { System.out.printf("System.out.printf(\"something\");"); } } And now the output is System.out.printf("something"); So now the output of attempt #2 matches the statement in output #1, but we're back to the problem we had before, since we need the output of attempt #2 to match the statement in attempt #2. So is it possible to write a one-line printf statement that prints itself?

• How to create a gesture controlled rotating image for a UI

  - by ocdtrekkie

  I'm trying to figure out the best way to make an image rotate along with a user's finger dragging it left or right. I want to try and match the rate a user's finger is moving with the rate the image is rotating. I've got the basic setup for my application going, with the menus and whatnot I want to have, and that's all running great on the emulator, I'm just not sure how to approach this part. I can code all the logic I need for my app, I'm just not doing to well designing the UI, I have a picture in mind, I've actually made a couple mock images of it, I just can't figure out how to get it going in Android, and any help would be appreciated.

• Java, searching within a list of objects?

  - by Rick

  I'm a bit lost on the way to make this happen the fastest. I have a large list of objects that have basic variable attributes (with getters / setters) and I need to do a search in this list to find the objects within the list that match a given parameter I have found how to do a regular list search but I need to, for example search for the value of the result of doing a call getName() for each object in the list and get objects that have a result that matches my input. Something like below where the third argument is the result of the method call and the second is what I am trying to find. int index = Collections.binarySearch(myList, "value", getName()); Any advice is appreciated

• Java Program Compiles and Runs, but doesn't work

  - by Richard Long

  When I run this program I enter information in a text box, push the search button, but nothing happens. The program just sits there until I press Cntrl C to break it. It looks like it should work, but I can't figure out what is hanging the program up. Here is the code: First class: import java.io.*; import java.awt.*; import javax.swing.*; import java.awt.event.*; import java.util.*; public class NameGameFrame extends JFrame { public static String name; static JTextField textfield = new JTextField(20); static JTextArea textarea = new JTextArea(30,30); public static String num; public static String [] fields; public static int [] yearRank; public static boolean match; public static int getInts, marker, year, max; public static void main( String[] args) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setTitle("Name Game"); frame.setLocation(500,400); frame.setSize(800,800); JPanel panel = new JPanel(new GridBagLayout()); GridBagConstraints c = new GridBagConstraints(); JLabel label = new JLabel("Enter the Name or Partial Name to search:"); c.gridx = 0; c.gridy = 0; c.insets = new Insets(2,2,2,2); panel.add(label,c); c.gridx = 0; c.gridy = 1; panel.add(textarea,c); JButton button = new JButton("Search"); c.gridx = 1; c.gridy = 1; panel.add(button,c); c.gridx = 1; c.gridy = 0; panel.add(textfield,c); frame.getContentPane().add(panel, BorderLayout.NORTH); frame.pack(); frame.setVisible(true); button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent ae) { name = textfield.getText(); java.io.File file = new java.io.File("namesdata.txt"); try { Scanner input = new Scanner(file); num = input.nextLine(); NameRecord nr = new NameRecord(name); while (input.hasNext()) { if(match = num.toLowerCase().contains(name.toLowerCase())) { nr.getRank(); nr.getBestYear(marker); } } } catch(FileNotFoundException e) { System.err.format("File does not exist\n"); } textarea.setText(fields[0]); } }); } } This is the second class: import java.io.*; import java.util.*; public class NameRecord { public NameRecord( String name) { } public static int getBestYear(int marker) { switch (marker) { case 1: year = 1900; break; case 2: year = 1910; break; case 3: year = 1920; break; case 4: year = 1930; break; case 5: year = 1940; break; case 6: year = 1950; break; case 7: year = 1960; break; case 8: year = 1970; break; case 9: year = 1980; break; case 10: year = 1990; break; case 11: year = 2000; break; } return year; } public static int getRank() { fields = num.split(" "); max = 0; for (int i = 1; i<12; i++) { getInts = Integer.parseInt(fields[i]); if(getInts>max) { max = getInts; marker = i; } } return max; } }

• What wiki tools exist to generate shippable user doc from a wiki?

  - by tletnes

  I am looking into using a wiki (prefer mediawiki, but not a req.) as the repository for developer generated documentation (User Guides, Release Notes, Application Notes, Errata, etc.) from a collaborative/easy-to-update point of view a wiki seems like a good match, however since this documentation will ultimately ship to customers we want to be able to export the documents in their final state (e.g. during the release cycle) to static versions that no longer include histories. Ideally the export would leave the document n a form where errors could be easily fixed by a non-programmer It would be good if niceties like section ordering and table of contents were available, or easy to add after the fact. Are any tools with features like these avalible?

• C++ - Print Out Objects From Set

  - by John Smith

  If I have a C++ set, declaration set personList; with iterator, set::const_iterator location; how can I print out the contents of the set? They are all person objects, and I have overridden the operator<< for Person. The line that errors is: cout << location and it's in a basic for loop. Netbeans gives the following error: proj.cpp:78: error: no match for ‘operator<<’ in ‘std::cout << location’ so it looks like it wants an override for the iterator's <<. Basically, I am taking objects that used to be stored in an array format, but are now in a set. What is the equivalent to cout << array[i] for sets?

• Grep for multiple patterns over multiple files

  - by prelic

  I've been googling around, and I can't find the answer I'm looking for. Say I have a file, text1.txt, in directory mydir whose contents are: one two and another called text2.txt, also in mydir, whose contents are: two three four I'm trying to get a list of files (for a given directory) which contain all (not any) patterns I search for. In the example I provided, I'm looking for output somewhere along the lines of: ./text1.txt or ./text1.txt:one ./text1.txt:two The only things I've been able to find are concerning matching any patterns in a file, or matching multiple patterns in a single file (which I tried extending to a whole directory, but received grep usage errors). Any help is much appreciated. Edit-Things I've tried grep "pattern1" < ./* | grep "pattern2" ./* "ambiguous redirect" grep 'pattern1'|'pattern2' ./* returns files that match either pattern

• Examining a lambda expression at runtime in C#

  - by Ben Aston

  I have a method Get on a type MyType1 accepting a Func<MyType2, bool> as a parameter. An example of its use: mytype1Instance.Get(x => x.Guid == guid)); I would like create a stub implementation of the method Get that examines the incoming lambda expression and determines what the value of guid is. Clearly the lambda could be "anything", but I'm happy for the stub to make an assumption about the lambda, that it is trying to match on the Guid property. How can I do this? I suspect it involves the use of the built-in Expression type?

• MVC route with id and sub-action

  - by Dan Revell

  I can't figure out what I need to do with MVC routing to make this work Here's my one route: routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "{controller}/{id}/{action}", defaults: new { id = RouteParameter.Optional, action = RouteParameter.Optional } ); The request /Shipments/ works great. The request /Shipments/3/Packages works great. The request /Shipments/3 however fails with the error: Multiple actions were found that match the request: System.Linq.IQueryable`1[Api.Controllers.RequisitionsController+PackageRequisitionWithTracking] GetPackageRequisitions(Int32) on type Api.Controllers.RequisitionsController Api.Models.ShipmentRequisition GetShipmentRequisitions(Int32) on type Api.Controllers.RequisitionsController It can't seem to differentiate between: public ShipmentRequisition GetShipmentRequisitions(int id) and [ActionName("Packages")] public IQueryable<PackageRequisitionWithTracking> GetPackageRequisitions(int id) I would have thought the lack of action name on the get shipment by id would allow that route to work.

• Document/Scripts management for R code

  - by harshsinghal

  Hi useRs, I am looking for a solution that allows me to keep a track of a multitude of R scripts that I create for various projects and purposes. Some scripts are easily tracked to specific projects, whereas others are "convenience" functions created to serve a set of tasks. Is there a way I can create a central DB and query it to find which scripts match most appropriately? I could create a system using a DBMS manually, but are users aware of anything in general or specific to R, that comes in the form of a software tool (maybe FOSS) ?

How can I have multiple where condition clauses in the THEN of the the same CASE? How can I make this work?
