  • How to make a structure map powered viewengine in asp.net mvc

    - by Andrew Bullock
    My views extend a base view class ive made: public class BaseView : ViewPage At the moment im calling ObjectFactory.GetInstance inside this class' constructor to get some interface implementations but id like to use structuremap to inject them as constructor arguments. Im using a structuremapcontrollerfactory to create my controllers, but how can i do the same for views? I know i can implement a custom ViewEngine, but using reflector to look at the mvc default viewengine and its dependencies, it seems to go on and on and i'd rather not have to re-implement stuff thats already there. Has anyone got a cunning idea how to solve this? I know i could make things easier with setter instead of constructor injection but id rather avoid that if possible.

  • Project Euler 7 Scala Problem

    - by Nishu
    I was trying to solve Project Euler problem number 7 using scala 2.8 First solution implemented by me takes ~8 seconds def problem_7:Int = { var num = 17; var primes = new ArrayBuffer[Int](); primes += 2 primes += 3 primes += 5 primes += 7 primes += 11 primes += 13 while (primes.size < 10001){ if (isPrime(num, primes)) primes += num if (isPrime(num+2, primes)) primes += num+2 num += 6 } return primes.last; } def isPrime(num:Int, primes:ArrayBuffer[Int]):Boolean = { // if n == 2 return false; // if n == 3 return false; var r = Math.sqrt(num) for (i <- primes){ if(i <= r ){ if (num % i == 0) return false; } } return true; } Later I tried the same problem without storing prime numbers in array buffer. This take .118 seconds. def problem_7_alt:Int = { var limit = 10001; var count = 6; var num:Int = 17; while(count < limit){ if (isPrime2(num)) count += 1; if (isPrime2(num+2)) count += 1; num += 6; } return num; } def isPrime2(n:Int):Boolean = { // if n == 2 return false; // if n == 3 return false; var r = Math.sqrt(n) var f = 5; while (f <= r){ if (n % f == 0) { return false; } else if (n % (f+2) == 0) { return false; } f += 6; } return true; } I tried using various mutable array/list implementations in Scala but was not able to make solution one faster. I do not think that storing Int in a array of size 10001 can make program slow. Is there some better way to use lists/arrays in scala?

  • [ActionScript 3] Array subclasses cannot be deserialized, Error #1034

    - by aaaidan
    I've just found a strange error when deserializing from a ByteArray, where Vectors cannot contain types that extend Array: there is a TypeError when they are deserialized. TypeError: Error #1034: Type Coercion failed: cannot convert []@4b8c42e1 to com.myapp.ArraySubclass. at flash.utils::ByteArray/readObject() at com.myapp::MyApplication()[/Users/aaaidan/MyApp/com/myapp/MyApplication.as:99] Here's how: public class Application extends Sprite { public function Application() { // register the custom class registerClassAlias("MyArraySubclass", MyArraySubclass); // write a vector containing an array subclass to a byte array var vec:Vector.<MyArraySubclass> = new Vector.<MyArraySubclass>(); var arraySubclass:MyArraySubclass = new MyArraySubclass(); arraySubclass.customProperty = "foo"; vec.push(arraySubclass); var ba:ByteArray = new ByteArray(); ba.writeObject(arraySubclass); ba.position = 0; // read it back var arraySubclass2:MyArraySubclass = ba.readObject() as MyArraySubclass; // throws TypeError } } public class MyArraySubclass extends Array { public var customProperty:String = "default"; } It's a pretty specific case, but it seems very odd to me. Anyone have any ideas what's causing it, or how it could be fixed?

  • map xml element to xsd complexType based on attribute

    - by Joshua Johnson
    Assume there exists an XML instance document that looks like this: <root> <object type="foo"> <!-- ... --> </object> <object type="bar"> <!-- ... --> </object> </root> My goal is to have a small (static) schema that verifies proper <element type="xxx" /> syntax for objects, and another schema (more prone to change) that verifies the contents of each object element against a complexType that matches the type attribute: <complexType name="foo"><!--should match object with type="foo"--></complexType> <complexType name="bar"><!--should match object with type="bar"--></complexType> What is the best way to accomplish this (or something similar)?

  • calloc v/s malloc and time efficiency

    - by yCalleecharan
    Hi, I've read with interest the post "c difference between malloc and calloc". I'm using malloc in my code and would like to know what difference I'll have using calloc instead. My present (pseudo)code with malloc: Scenario 1 int main() { allocate large arrays with malloc INITIALIZE ALL ARRAY ELEMENTS TO ZERO for loop //say 1000 times do something and write results to arrays end for loop FREE ARRAYS with free command } //end main If I use calloc instead of malloc, then I'll have: Scenario2 int main() { for loop //say 1000 times ALLOCATION OF ARRAYS WITH CALLOC do something and write results to arrays FREE ARRAYS with free command end for loop } //end main I have three questions: Which of the scenarios is more efficient if the arrays are very large? Which of the scenarios will be more time efficient if the arrays are very large? In both scenarios,I'm just writing to arrays in the sense that for any given iteration in the for loop, I'm writing each array sequentially from the first element to the last element. The important question: If I'm using malloc as in scenario 1, then is it necessary that I initialize the elements to zero? Say with malloc I have array z = [garbage1, garbage2, garbage 3]. For each iteration, I'm writing elements sequentially i.e. in the first iteration I get z =[some_result, garbage2, garbage3], in the second iteration I get in the first iteration I get z =[some_result, another_result, garbage3] and so on, then do I need specifically to initialize my arrays after malloc?

  • EF4 CTP5 - Map foreign key without object references?

    - by anon
    I feel like this should have a simple answer, but I can't find it. I have 2 POCOs: public class Category { public int Id { get; set; } public string Name { get; set; } } public class Product { public int Id { get; set; } public int CategoryId { get; set; } } Notice that there are no object references on either POCO. With Code-First, how do I make EF4 CTP5 define a relationship between the two database tables? (I know this is an unusual scenario, but I am exploring what's possible and what's not with Code-First)

  • Convet long/lat to pixel x/y on a given picure.

    - by kalininew
    I have a city "map" (for example - Moscow). She in accuracy repeats the contours the given city in google maps (that is it is copied from google maps and it is a little processed, but the sense remained the same). Also I have object co-ordinates in a city (in co-ordinates of google). Problem: how to translate google co-ordinates to the co-ordinates of my picture (that is in pixels on OX and OY on a picture). That is I receive google-co-ordinates and it is necessary for me to draw this point on my picture. I know that on small scales (for example on city scales) it to make simply enough (it is necessary to learn what google-co-ordinates has one of picture corners, then to learn "price" of one pixel in google-co-ordinates on a picture on axes OX and OY separately). But on the big scales (country scale) "price" of one pixel will be not a constant, and will vary strongly enough and the method described above cannot be applied. How to solve a problem on country scales?

  • Map large integer to a phrase

    - by Alexander Gladysh
    I have a large and "unique" integer (actually a SHA1 hash). I want (for no other reason than to have fun) to find an algorithm to convert that SHA1 hash to a (pseudo-)English phrase. The conversion should be reversible (i.e., knowing the algorithm, one must be able to convert the phrase back to SHA1 hash.) The possible usage of the generated phrase: the human readable version of Git commit ID, like a motto for a given program version (which is built from that commit). (As I said, this is "for fun". I don't claim that this is very practical — or be much more readable than the SHA1 itself.) A better algorithm would produce shorter, more natural-looking, more unique phrases. The phrase need not make sense. I would even settle for a whole paragraph of nonsense. (Though quality — englishness — of a paragraph should probably be better than for a mere phrase.) A variation: it is OK if I will be able to work only with a part of hash. Say, first six digits is OK. Possible approach: In the past I've attempted to build a probability table (of words), and generate phrases as Markov chains, seeding the generator (picking branches from probability tree), according to the bits I read from the SHA. This was not very successful, the resulting phrases were too long and ugly. I'm not sure if this was a bug, or the general flaw in the algorithm, since I had to abandon it early enough. Now I'm thinking about attempting to solve the problem once again. Any advice on how to approach this? Do you think Markov chain approach can work here? Something else?

  • Mysteriously empty $_POST array

    - by Lex
    Hi all! I have the following HTML/PHP page: <?php if(empty($_SERVER['CONTENT_TYPE'])) { $type = "application/x-www-form-urlencoded"; $_SERVER['CONTENT_TYPE'] = $type; } echo "<pre>"; var_dump($_POST); var_dump(file_get_contents("php://input")); echo "</pre>"; ?> <form method="post" action="test.php"> <input type="text" name="test[1]" /> <input type="text" name="test[2]" /> <input type="text" name="test[3]" /> <input type="submit" name="action" value="Go" /> </form> As you can see, the form will submit and the expected output is a POST array with one array in it containing the filled in values and one entry "action" with the value "Go" (the button). However, no matter what values I enter in the fields; the result is always: array(2) { ["test"]=> string(0) "" ["action"]=> string(2) "Go" } string(16) "test=&action=Go&" Somehow, the array named test is emptied, the "action" variable does make it through. I've used the Live HTTP Headers extension for Firefox to check whether the POST fields get submitted, and they do. The relevant information from Live HTTP Headers (with a, b and c filled in as values in the textboxes): Content-Type: application/x-www-form-urlencoded Content-Length: 51 test%5B1%5D=a&test%5B2%5D=b&test%5B3%5D=c&action=Go Does anybody have any idea as to why this is happening? I'm freaking out on this one, it has cost me so much time already...

  • android custom map marker bounds

    - by max4ever
    Hello i am using a resized version of this marker( http://www.clker.com/clipart-orange-pin-4.html ) for showing markers in google maps on android. The problem is i don't know how to make the marker point match the coordinates. The arrow point is at about 1/5 of the Width coordinates and MAX of the Height. here is my class public class GestionaleItemizedOverlay extends com.google.android.maps.ItemizedOverlay { public GestionaleItemizedOverlay(Drawable defaultMarker, Context context) { //super(boundCenterBottom(defaultMarker)); super(boundCenter(defaultMarker)); this.mContext = context; } ... And this this.marker_poi = this.getContext().getResources().getDrawable(R.drawable.marker); this.marker_poi.setBounds(this.marker_poi.getIntrinsicWidth() / 2, this.marker_poi.getIntrinsicHeight(), this.marker_poi.getIntrinsicWidth() / 2, 0); new GestionaleItemizedOverlay(this.poi, this.context); Do i need to setBounds on the marker before passing it to the constructor? and why does super(defaultMarker) makes all the markers not to show ?

  • Iterating over a HashMap with JSTL, always getting last Object

    - by hkansal
    Hello, I have a Map, which I tried to iterate over with JSTL. Somehow I could not accomplish even this basic task. I also referred the questions here and here, but that is what I am already doing, still no success. What I tried to do was: <c:forEach items="${myMap}" var="myEntry"> ${myEntry.key} + ${myEntry.value} </c:forEach> But I always get the last object. Maybe I am missing something trivial, please advise. Thank You

  • kick off a map reduce job from my java/mysql webapp

    - by Brian
    Hi guys, I need a bit of archecture advice. I have a java based webapp, with a JPA based ORM backed onto a mysql relational database. Now, as part of the application I have a batch job that compares thousands of database records with each other. This job has become too time consuming and needs to be parallelized. I'm looking at using mapreduce and hadoop in order to do this. However, I'm not too sure about how to integrate this into my current architecture. I think the easiest initial solution is to find a way to push data from mysql into hadoop jobs. I have done some initial research on this and found the following relevant information and possibilities: 1) https://issues.apache.org/jira/browse/HADOOP-2536 this gives an interesting overview of some inbuilt JDBC support 2) This article http://architects.dzone.com/articles/tools-moving-sql-database describes some third party tools to move data from mysql to hadoop. To be honest I'm just starting out with learning about hbase and hadoop but I really don't know how to integrate this into my webapp. Any advice is greatly appreciated. cheers, Brian

  • How to insert an Array/Objet into SQL (bestpractice)

    - by Jason
    I need to store three items as an array in a single column and be able to quickly/easily modify that data in later functions. [---YOU CAN SKIP THIS PART IF YOU TRUST ME--] To be clear, I love and use x_ref tables all the time but an x_ref doesn't work here because this is not a one-to-many relationship. I am making a project management tool that among other things, assigns a user to a project and assigns hours to that project on a weekly basis, per user, sometimes for weeks many weeks into the future. Of course there are many projects, a project can have many team members, a team member can be involved with many projects at one time BUT its not one-to-many because a team member can be working many weeks on the same project but have different hours for different weeks. In other words, each object really is unique. Also/finally, this data can be changed at any time by any team-member - hence it needs to be easily to manipulate. Basically, I need to handle three values (the team member, the week we're talking about, and how many hours) dropped into a project row in the projects table (under the column for project team members) and treated as one item - a team member - that will actually be part of a larger array of all the team members involved on the project. [--END SKIP, START READING HERE :) --] So assuming that the application's general schema and relation tables aren't total crap and that we are in fact up against a wall in this one case to use an array/object as a value for this column, is there a best practice for that? Like a particular SQL data-type? A particular object/array format? CSV? JSON? XML? Most of the app is in C# but (for very odd reasons that I won't explain) we could really use any environment if there is a particular one that handles this well. For the moment, I am thinking either (webservice + JS/JSON) or PHP unserialize/serialize (but I am bit sketched out by the PHP solution because it seems a bit cumbersome when using ajax?) Thoughts anyone?

  • Error while trying to install Community Engine: NameError - "Undefined local variable or method 'map

    - by floatingfrisbee
    I'm trying to install Community Engine using the instructions here: http://github.com/bborn/communityengine At first I thought it might be because I had Rails 2.3.5 and desert 0.5.3 which were higher versions than what was mentioned on the installation site.

  • What next in the career map for a Lead QA Engineer

    - by chandran
    I am a Lead QA Engineer in a Software company and at a stage in my career wherein i need to plan my next move. Option 1: The very obvious move would be to stay as a QA Lead and eventually become a QA Manager. But i don't see very good prospects/future after that. Or am i wrong? Option 2: I love programming/coding, though i haven't spent a whole lot of time on that. So a direct move to becoming a Software Developer is not possible. Will moving to Test Automation eventually lead me to development. Even so, am i looking at step-down in pay and career-level. Option 3: Moving to Product Management. Is this even possible and if so what would be the best approach. Appreciate all your responses in advance. Thanks.
