    ajax silverlight flex 2014-2-16 12:06:08
    Ajax, Flex and Silverlight are a few ways to make more interactive web applications. What kinds of factors would you consider when deciding which to use for a new web application? Does any one of them offer better cross-platform compatibility, performance, developer tools or community support?

    asp.net ajax silverlight 2014-2-16 9:44:42
    What’s the advantage of one over the other? I am so tempted to implement everything in silverlight now, so is ASP.NET, in particular, with Ajax, going to be dead?For an enterprise solution especially, with 100+ views and 1000+ pages, is it still feasible?Why isn’t silverlight adopted that much by most enterprises? It is mostly used for videos and galleries, etc.Cheers

    I’m trying to create a tile based world map like Tribal Wars has or The-West games. I created a little bit of it but it loads too slow when you drag the map with your mouse.My algorithm works like this:On page load:load the tiles from 1 to 19(x1 to y1 and x2 to y2) via JQuery’s $.post method(I need the screen’s width and height for that 19=1900/tile_width, because I want the map to fill the entire page) append the returned data(tiles) to the screen (so far so good)On map drag:load again via .pos

    c++ arrays vector c++11 stdvector 2014-2-17 0:48:43
    I’d like to use std::array from C++11 as a field of my own class. It takes two template parameters (first defines type of data, second defines size of an array).But I know the second parameter only in constructor. I’m not familiar with C++11 standard, but I suppose that it’s impossible to set a template parameter during execution.Are there any alternatives for std::array? std::vector is probably a little too much, cause I will never change the size of it.

    I am trying to create an array of arrays of arrays etc…, except I don’t know how many nested levels deep it needs to be until runtime.Depending on the input, I might need either int[], int[][], int[][][][][][], or anything else. (For context, I am trying to construct an N-dimensional grid for a cellular automaton, where N is passed as a parameter.)I don’t have any code for you because I have no idea how to go about this; I suspect is not possible at all using just arrays.

    arrays algorithm time-complexity space-complexity 2014-2-16 21:25:58
    You are given an array of integers. You have to output the largest range so that all numbers in the range are present in the array. The numbers might be present in any order. For example, suppose that the array is{2, 10, 3, 12, 5, 4, 11, 8, 7, 6, 15}Here we find two (nontrivial) ranges for which all the integers in these ranges are present in the array, namely [2,8] and [10,12]. Out of these [2,8] is the longer one. So we need to output that.When I was given this question, I was asked to do th

    I am working with data from netcdf files, with multi-dimensional variables, read into numpy arrays. I need to scan all values in all dimensions (axes in numpy) and alter some values. But, I don’t know in advance the dimension of any given variable. At runtime I can, of course, get the ndims and shapes of the numpy array. How can I program a loop thru all values without knowing the number of dimensions, or shapes in advance? If I knew a variable was exactly 2 dimensions, I would doshp=myarray.sha

    In knockout-2.2.d.ts we have:interface KnockoutObservableAny extends KnockoutObservableBase {(): any;(value): void; }I understand that (): is used to declare a function with an empty parameter list and a return type after the colon.However I don’t understand the lack of a function identifier in front of the brackets.I would have expected something like functionName(): any; What does this “anonymous” function mean? How do I interpret this nameless function, thanks.

    javascript asp.net-mvc-4 knockout.js razor-2 2014-2-10 20:43:01
    First off, this code does work, but it gives me a low level of annoyance that I’d like to be rid of. I have a .cshtml page that is built using the razor syntax. There is a big, nasty, knockout object living behind the scenes to which many things on the page are bound. Currently, when instantiating that knockout model, I’m doing so by serializing the C# viewmodel object in question within a string literal like below.<script type=”text/javascript”>$(document).ready(function() {var data = @Ht

    I like knockout.js, the only problem is Visual Studio knows nothing about this framework, so it does not prevent me from silly things like assigning some value to observable property with ‘=’ operator which makes it regular property, and it’s not easy to reveal at compile time and often at runtime even. I wonder is there any syntax checker/highlighter for Visual Studio 2010 that helps me prevent faults like this? What about VS 2011? It might be a great help for developers who are new to knockou
