  • Instantiate a model when the kind of model needed is represented as a string argument

    - by indiehacker
    My input data is a string representing the kind of datastore model I want to make. In python, I am using the eval() function to instantiate the model (below code), but this seems overly complex so I was wondering if there is a simpler way people normally do this? >>>model_kind="TextPixels" >>>key_name_eval="key_name" >>>key_name="key_name" >>>kwargs {'lat': [0, 1, 2, 3], 'stringText': 'boris,ted', 'lon': [0, 1, 2, 8], 'zooms': [0, 10]} >>>obj=eval( model_type + '(key_name='+tester+ ',**kwargs )' ) >>>obj <datamodel.TextPixels object at 0xed8808c>

  • deep or shallow copying?

    - by Dervin Thunk
    Dear all. I was wondering if there are examples of situations where you would purposefully pass an argument by value (deep copy) in C. For instance, passing a char to a function is usually cheaper in space than passing a char* (if there's no need to share the value), since char is 1 byte and pointers are, well, whatever they are in the architecture (4 in my 32 bit machine). ?(When) do you want to pass (big) deep copies to functions? if so, why?

  • F# mutual recursion between modules

    - by rwallace
    For recursion in F#, existing documentation is clear about how to do it in the special case where it's just one function calling itself, or a group of physically adjacent functions calling each other. But in the general case where a group of functions in different modules need to call each other, how do you do it?

  • In node.js slow readable stream attached to a faster pushing message queue eats up memory

    - by Vishal
    In my node.js program I have a response stream attached to a message queue (zeromq) delivering data at a very high rate. Due to slow network connection the response stream and its underlying implementation is unable to consume data at that pace thus occupying a lot of memory. Do you have any suggestion to solve this problem. For reference please see the code snippet below: zmq.on("message", function(data) { res.write(data); // End response on some event });

  • foo and _foo - about variables inside a class

But where does it come from? self._foo and self.foo are different, aren't they?

  • AS3: How can I require a method argument to implement multiple interfaces?

    - by Anders
    The argument to my method func() must implement the two unrelated interfaces IFoo and IBar. Is there a better way of doing this than declaring another interface only for this purpose that inherits from IFoo and IBar and using that interface as the argument type? public interface IFooBar implements IFoo, IBar { } public function func(arg:IFooBar):void { } I'm developing for Flash Player 9.

  • ASP.NET MVC 3 NOT showing appropriate view, action called using jquery

    - by TunAntun
    I have a small problem. My action is : public ViewResult SearchForRooms(int HotelDDL) { List<Room> roomsInHotel = bl.ReturnRoomsPerHotel(HotelDDL); return View(roomsInHotel); } Here is the jquery that is calling the action: <script type="text/javascript" language="javascript"> $(document).ready(function () { $("#HotelDDL").change(function () { var text = $("#HotelDDL option:selected").text(); var value = $("#HotelDDL option:selected").val(); alert("Selected text=" + text + " Selected value= " + value); $.post("/Home/SearchForRooms", { HotelDDL: $("#HotelDDL option:selected").val() }); }); }); </script> And finally, here is the View that should be called: @model IEnumerable<RoomReservation.Entities.Entities.Room> @{ ViewBag.Title = "Search"; } <h2>Result</h2> <table> <tr> <th> City </th> <th> Hotel </th> <th> Room label </th> <th> Number of beds </th> <th> Price per night </th> <th></th> </tr> @foreach (var item in Model) { <tr> <td> @Html.DisplayFor(modelitem=>item.Hotel.City.Name) </td> <td> @Html.DisplayFor(modelItem => item.Hotel.Name) </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> <td> @Html.DisplayFor(modelItem => item.NumberOfBeds) </td> <td> @Html.DisplayFor(modelItem => item.PricePerNight) </td> </tr> } </table> Everthing is working ok (databse return all rooms correctly) except final view rendering. I have tried Phil's tool but it doesn't give me any suspicious hints: RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes); So, why is it not showing after jscript send it's post method to SearchForRooms()? Thank you P.S. If you need any other piece of code please just say so.

  • Approaching Java from a Ruby perspective

    - by Travis
    There are plenty of resources available to a Java developer for getting a jump-start into Ruby/Rails development. The reverse doesn't appear to be true. What resources would you suggest for getting up-to-date on the current state of java technologies? How about learning how to approach DRY (don't repeat yourself) without the use of metaprogramming? Or how to approach various scenarios where a ruby developer is used to passing in a function (proc/lambda/block) as an argument (callbacks, etc)?

  • Should I consider memmove() O(n) or O(1) ?

    - by Andrei Ciobanu
    Hello, this may be a silly question, but I want to calculate the complexity of one of my algorithms, and I am not sure what complexity to consider for the memmove() function. Can you please help / explain ? void * memmove ( void * destination, const void * source, size_t num ); So is the complexity O(num) or O(1). I suppose it's O(num), but I am not sure as I lack for now the understanding of what's going on under the hood.
