  • Proving that a function f(n) belongs to a Big-Theta(g(n))

    - by PLS
    Its a exercise that ask to indicate the class Big-Theta(g(n)) the functions belongs to and to prove the assertion. In this case f(n) = (n^2+1)^10 By definition f(n) E Big-Theta(g(n)) <= c1*g(n) < f(n) < c2*g(n), where c1 and c2 are two constants. I know that for this specific f(n) the Big-Theta is g(n^20) but I don't know who to prove it properly. I guess I need to manipulate this inequality but I don't know how

  • RIA Services: custom autorization

    - by Budda
    Here is a good example how to create custom autorization for RIA services: http://stackoverflow.com/questions/1195326/ria-services-how-can-i-create-custom-authentication In my case a silverlight-pages will be displayed as a part of HTML-content and user authorisation is already implemented on the server-side (ASP.NET Membership is not used). It is required to show on the silverlight pages different information for authorised and non-authorised users. Is there any possibility to track on the Silverlight side if user is already authorized on the server side (on the usual ASP.NET web-site)? Please adivse how to do this. Thank you in advance.

  • Is it safe to use Select Top and Delete Top in sequence?

    - by Rob Nicholson
    I often write T-SQL loops that look like this While Exists (Select * From #MyTable) Begin Declare @ID int, @Word nvarchar(max) Select Top 1 @ID=ID, @Word=[Word] From #MyTable -- Do something -- Delete #MyTable Where ID=@ID End Works a treat but I noticed the new Delete Top function which would be useful when #MyTable is just a list of strings. In this case, would this work: While Exists (Select * From #MyTable) Begin Declare @Word nvarchar(max) Select Top 1 @Word=[Word] From #MyTable -- Do something -- Delete Top(1) #MyTable End Well yes, it works in my test script but is this safe? Will Select Top 1 and Delete Top(1) always refer to the same record or is Top a little more vague. Thanks, Rob.

  • Why can't the JVM just make autoboxing "just work"?

    - by Pyrolistical
    Autoboxing is rather scary. While I fully understand the difference between == and .equals I can't but help have the follow bug the hell out of me: final List<Integer> foo = Arrays.asList(1, 1000); final List<Integer> bar = Arrays.asList(1, 1000); System.out.println(foo.get(0) == bar.get(0)); System.out.println(foo.get(1) == bar.get(1)); That prints true false Why did they do it this way? It something to do with cached Integers, but if that is the case why don't they just cache all Integers used by the program? Or why doesn't the JVM always auto unbox to primitive? Printing false false or true true would have been way better.

  • How does Entity Framework 4.0 determine which parameters are required for the factory method of an e

    - by Scott Davies
    Hi, I am working with Entity Framework 4.0 (VS 2010 Beta 2, NOT RC). I can model the EDM and produce the required database. When I ask VS to generate the code for the model, it generates the expected .designer.cs file. When I look at the factory methods for each entity that the designer has generated, I've noticed that it doesn't include all of the properties of the entity. Is it correct to say that the factory method only includes properties that cannot be null ? This appears to be the case, but I'm not entirely sure. Thanks, Scott

  • AS3 Font embedding problem in ComboBox on a loaded movie clip

    - by Arafat
    Hi all, I have three movie clips, say, LoaderMC, ChildMC1, and ChildMC2. ChildMC1 has TLFTextfields in it with embedded fonts. ChildMC2 has both TLFTextfields as well as combo boxes.(with embedded fonts) When I compile those movieclips separately, I can view the combo box texts without any problem. If I load the ChildMC1 and ChildMC2 into the LoaderMC, the texts doesn't appear at all on both TLFtextfields and Combo Boxes. I tried embedding the fonts in the LoaderMC, then, TLFTextfields was able to show the texts but still the ComboBoxes couldn't display the text. If I don't embed the fonts in the combo box, I can able to view the texts. What could be the problem? I read an article which says, "No one has completely understood the font embedding in flash AS3, we just have to do trial and error, to get it done" I don't know how far it is true, but in my case it seems, I should agree! Please help me...

  • Drupal: Create custom search

    - by Dr. Hfuhruhurr
    I'm trying to create a custom search but getting stuck. What I want is to have a dropdownbox so the user can choose where to search in. These options can mean 1 or more content types. So if he chooses options A, then the search will look in node-type P,Q,R. But he may not give those results, but only the uid's which will be then themed to gather specific data for that user. To make it a little bit clearer, Suppose I want to llok for people. The what I'm searching in is 2 content profile types. But ofcourse you dont want to display those as a result, but a nice picture of the user and some data. I started with creating a form with a textfield and the dropdown box. Then, in the submit handler, i created the keys and redirected to another pages with those keys as a tail. This page has been defined in the menu hook, just like how search does it. After that I want to call hook_view to do the actual search by calling node_search, and give back the results. Unfortunately, it goes wrong. When i click the Search button, it gives me a 404. But am I on the right track? Is this the way to create a custom search? Thx for your help. Here's the code for some clarity: <?php // $Id$ /* * @file * Searches on Project, Person, Portfolio or Group. */ /** * returns an array of menu items * @return array of menu items */ function vm_search_menu() { $subjects = _vm_search_get_subjects(); foreach ($subjects as $name => $description) { $items['zoek/'. $name .'/%menu_tail'] = array( 'page callback' => 'vm_search_view', 'page arguments' => array($name), 'type' => MENU_LOCAL_TASK, ); } return $items; } /** * create a block to put the form into. * @param $op * @param $delta * @param $edit * @return mixed */ function vm_search_block($op = 'list', $delta = 0, $edit = array()) { switch ($op) { case 'list': $blocks[0]['info'] = t('Algemene zoek'); return $blocks; case 'view': if (0 == $delta) { $block['subject'] = t(''); $block['content'] = drupal_get_form('vm_search_general_form'); } return $block; } } /** * Define the form. */ function vm_search_general_form() { $subjects = _vm_search_get_subjects(); foreach ($subjects as $key => $subject) { $options[$key] = $subject['desc']; } $form['subjects'] = array( '#type' => 'select', '#options' => $options, '#required' => TRUE, ); $form['keys'] = array( '#type' => 'textfield', '#required' => TRUE, ); $form['submit'] = array( '#type' => 'submit', '#value' => t('Zoek'), ); return $form; } function vm_search_general_form_submit($form, &$form_state) { $subjects = _vm_search_get_subjects(); $keys = $form_state['values']['keys']; //the search keys //the content types to search in $keys .= ' type:' . implode(',', $subjects[$form_state['values']['subjects']]['types']); //redirect to the page, where vm_search_view will handle the actual search $form_state['redirect'] = 'zoek/'. $form_state['values']['subjects'] .'/'. $keys; } /** * Menu callback; presents the search results. */ function vm_search_view($type = 'node') { // Search form submits with POST but redirects to GET. This way we can keep // the search query URL clean as a whistle: // search/type/keyword+keyword if (!isset($_POST['form_id'])) { if ($type == '') { // Note: search/node can not be a default tab because it would take on the // path of its parent (search). It would prevent remembering keywords when // switching tabs. This is why we drupal_goto to it from the parent instead. drupal_goto($front_page); } $keys = search_get_keys(); // Only perform search if there is non-whitespace search term: $results = ''; if (trim($keys)) { // Log the search keys: watchdog('vm_search', '%keys (@type).', array('%keys' => $keys, '@type' => $type)); // Collect the search results: $results = node_search('search', $type); if ($results) { $results = theme('box', t('Zoek resultaten'), $results); } else { $results = theme('box', t('Je zoek heeft geen resultaten opgeleverd.')); } } } return $results; } /** * returns array where to look for * @return array */ function _vm_search_get_subjects() { $subjects['opdracht'] = array('desc' => t('Opdracht'), 'types' => array('project') ); $subjects['persoon'] = array('desc' => t('Persoon'), 'types' => array('types_specialisatie', 'smaak_en_interesses') ); $subjects['groep'] = array('desc' => t('Groep'), 'types' => array('Villamedia_groep') ); $subjects['portfolio'] = array('desc' => t('Portfolio'), 'types' => array('artikel') ); return $subjects; }

  • Accessing the constructor by using Reflection

    - by Md. Rashim Uddin
    Assume the class is public and and the constructor is internal like as Public class A { private string text; internal A(string submittedText); public string StrText { get; } } In this case how could I Access the constructor by using Reflection. What I have done so far Type[] pTypes = new Type[1]; pTypes[0] = typeof(object); object[] argList = new object[1]; argList[0] = "Some Text"; ConstructorInfo c = typeof(A).GetConstructor (BindingFlags.NonPublic | BindingFlags.Instance, null, pTypes, null); A foo = (A)c.Invoke(BindingFlags.NonPublic, null, argList, Application.CurrentCulture); But it shows an error.

  • Is it viable and necessary to encrypt bytes?

    - by Shervin
    We have a requirement from customer that if someone gets access to the database, all data that includes personal information should be encrypted, so that when they do select calls, they shouldn't be able to see anything in clear text. Now this isn't any problem for Strings, but what about bytearrays? (that can potentially be quite huge (several 100mb)) When you do a select call, you get gibberish anyways. Is it possible for a hacker to somehow read the bytes and get the sensitive information without knowing how the structure of the object it is mapped against is? Because if that is the case, then I guess we should encrypt those bytes, even if they can potentially be quite huge. (I am guessing adding encryption will make them even bigger)

  • Reading HttpURLConnection InputStream - manual buffer or BufferedInputStream?

    - by stormin986
    When reading the InputStream of an HttpURLConnection, is there any reason to use one of the following over the other? I've seen both used in examples. Manual Buffer: while ((length = inputStream.read(buffer)) > 0) { os.write(buf, 0, ret); } BufferedInputStream is = http.getInputStream(); bis = new BufferedInputStream(is); ByteArrayBuffer baf = new ByteArrayBuffer(50); int current = 0; while ((current = bis.read()) != -1) { baf.append(current); } EDIT I'm still new to HTTP in general but one consideration that comes to mind is that if I am using a persistent HTTP connection, I can't just read until the input stream is empty right? In that case, wouldn't I need to read the message length and just read the input stream for that length? And similarly, if NOT using a persistent connection, is the code I included 100% good to go in terms of reading the stream properly?

  • How GC collects resources in a static member in C#?

    - by carter-boater
    Dear all, I have a piece of code like this: Class Program { static StreamReader sr = null; static int var=0; static Program() { sr = new StreamReader("input.txt") } ~Program() { sr.Dispose(); } static void main(string args[]) { //do something with input here } } This may not be a good practice, but I just want to use this example to ask how the deconstructor and GC works. My question is: Will ~Program() get called at a non-determined time or it won't be called at all in this case. If the deconstructor won't get called, then how GC collect the unmanaged resources and managed resources. Thank you very much!

  • Why doesn't Visual Studio show an exception message when my exception occurs in a static constructor

    - by Tim Goodman
    I'm running this C# code in Visual Studio in debug mode: public class MyHandlerFactory : IHttpHandlerFactory { private static Dictionary<string, bool> myDictionary = new Dictionary<string, bool>(); static MyHandlerFactory() { myDictionary.Add("someKey",true); myDictionary.Add("someKey",true); // fails due to duplicate key } } Outside of the static constructor, when I get to the line with the error Visual Studio highlights it and pops up a message about the exception. But in the static constructor I get no such message. I am stepping through line-by-line, so I know that I'm getting to that line and no further. Why is this? (I have no idea if that fact that my class implements IHttpHandlerFactory matters, but I included it just in case.) This is VS2005, .Net 2.0

  • dynamic log4net appender name?

    Let's say i have 3 smtp appenders in same log4net file whose names are: <appender name = "emailDevelopment".. /> <appender name = "emailBeta".. /> <appender name = "emailProduction".. /> Let's say i have 3 different servers(Dev, Beta, Production). Depending upon the server, i want to fire the log. In case of Development server, it would fire log from "emailDevelopment". I have a system variable in each server named "ApplicationEnvironment" whose value is Development, Beta, Production based on the server names. Now is there anyway i can setup root in log4net so that it fires email depending upon the server name. <root> <priority value="ALL" /> <appender-ref ref="email<environment name from whose appender should be used>" /> </root>

  • How to rotate 4 images, fading between each one?

    - by Darryl Hein
    I have 4 images, which I want to fade between each other in a loop. I have something like the following: <img src="/images/image-1.jpg" id="featureImg1" /> <img src="/images/image-2.jpg" id="featureImg2" style="display:none;" /> <img src="/images/image-3.jpg" id="featureImg3" style="display:none;" /> <img src="/images/image-4.jpg" id="featureImg4" style="display:none;" /> I am up for revisions to the HTML, although I cannot use absolute positioning in this case. I am using jQuery else where on the site, so it's available. I also need to deal with an image not being loaded right away as the images are larger.

  • removing pairs of elements from numpy arrays that are NaN (or another value) in Python

    - by user248237
    I have an array with two columns in numpy. For example: a = array([[1, 5, nan, 6], [10, 6, 6, nan]]) a = transpose(a) I want to efficiently iterate through the two columns, a[:, 0] and a[:, 1] and remove any pairs that meet a certain condition, in this case if they are NaN. The obvious way I can think of is: new_a = [] for val1, val2 in a: if val2 == nan or val2 == nan: new_a.append([val1, val2]) But that seems clunky. What's the pythonic numpy way of doing this? thanks.

  • MFMailComposeViewController broke CSS styles in html template

    I use MFMailComposeViewController to send a message in html format. If my html template contains the css styles: <div class="margin:10 10 10 0"> <a href="domain.name">Go To</a></div> In this case it works good. But if I send: <a href="domain.name">Go&nbsp;To</a> then I see the letter that comes with broken styles as there (3D is not my misprint) <div style=3D"margin:10 10 10 10;"><a href=3D"www.google.com">Go=C2=A0To</a></div> Well as the letter goes broken when I insert in the template symbols from national alphabets. Somebody can tell what the problem and check with yourself?

  • Determine fonts used in postscript (.ps) file

    - by Bernard Vander Beken
    Given a postscript file that has the following header %!PS-Adobe-3.0 I would like to list all fonts used in the file. The output does not have to be perfect, but I need to make sure I get all references to any font being used. I am aware there are different types of fonts, and that a font may or may not be embedded in the postscript file. My current best idea is to grep/search for the word Font case insensitively and go from there. Will this get me all the font references? Any better way to achieve this? I tend to use .NET/C# for development purposes, but any solution is appreciated. Thanks, Bernard

  • How to dynamically choose two fields from a Linq query as a result

    - by Dr. Zim
    If you have a simple Linq query like: var result = from record in db.Customer select new { Text = record.Name, Value = record.ID.ToString() }; which is returning an object that can be mapped to a Drop Down List, is it possible to dynamically specify which fields map to Text and Value? Of course, you could do a big case (switch) statement, then code each Linq query separately but this isn't very elegant. What would be nice would be something like: (pseudo code) var myTextField = db.Customer["Name"]; // Could be an enumeration?? var myValueField = db.Customer["ID"]; // Idea: choose the field outside the query var result = from record in db.Customer select new { Text = myTextField, Value = myValueField };
