• RSA Factorization problem

  - by dada

  At class we found this programming problem, and currently, we have no idea how to solve it. The positive integer n is given. It is known that n = p * q, where p and q are primes, p<=q and |q-k*p|<10^5 for some given positive integer k. You must find p and q. Input: 35 1 121 1 1000730021 9 Output: 5 * 7 11 * 11 10007 * 100003 It's not a homework, we are just trying to solve some interesting problems. If you have some ideas, please post them here so we can try something, thanks.

• Can MySQL / SQL's short hand of "Using" be used without saying "Inner Join" ?

• Bind WCF webservice to specific network interface / IP

  - by Markus

  On a machine with multiple network cards I need to bind a WCF webservice to a specific network interface. It seems that the default is to bind on all network interfaces. The machine has two network adapters with the IPs 192.168.0.10 and 192.168.0.11. I have an Apache running that binds on 192.168.0.10:80 and need to run the webservice on 192.168.0.11:80. (Due to external circumstances I cannot choose another port.) I tried the following: string endpoint = "http://192.168.0.11:80/SOAP"; ServiceHost = new ServiceHost(typeof(TService), new Uri(endpoint)); ServiceHost.AddServiceEndpoint(typeof(TContract), Binding, ""); // or: ServiceHost.AddServiceEndpoint(typeof(TContract), Binding, endpoint); But it doesn't work; netstat -ano -p tcp always shows the webservice listening on 0.0.0.0:80, which is all interfaces (if I got that correct). When I start Apache first, it correctly binds to the other interface, which in turn prevents the WCF service to bind to "all". Any ideas?

• Drawing graphs in MS Excel somehow got complicated

  - by Ivan

  I want to draw several graphs and combine them into one figure. I will explain the problem in an example. Let's say that I want to draw two graphs with these points: Graph #1 (X and Y are defining a coordinate). X - Y _____ 1 - 5 2 - 5 5 - 7 9 - 10 Graph #2 X - Y _____ 6 - 8 8 - 12 9 - 7 12 - 8 15 - 11 21 - 11 What I do is that I create a chart and click on "Select Data". There I create two series and choose X and Y values. However, this doesn't work since it doesn't allow me to choose different X values for different graphs. Although I choose different for these two series, the second one is chosen for both. This is how it looks like in the end: Do you know how to fix this? I'm using Excel 2008 for Mac.

• Core-Data Can't pass managedObjectContext from app delegate to view controller

  I'm making a core-data application that is view based. I can create the managedObjectContext and 'use' it in the app delegate, but can not pass it to the mainviewcontroller.

• How to count incrementally in SQL SERVER

  - by joe

  Hi Folks, I am assigned a problem which i am not sure how to write it in SQL SEVER (version 5/8) yet. Here is the simple query and its output: Select location, date_time, Item_sold From Product Location Date_time Item_sold VA 12/10/2010 1:30:00 PM Candy VA 12/10/2010 3:30:00 PM Chips VA 12/13/2010 12:50:00 AM Wine DC 12/13/2010 8:00:00 AM Gum DC 12/13/2010 12:30:00 PM Bags DC 12/13/2010 1:16:00 PM Cheese DC 12/13/2010 12:00:00 AM Hotdog NJ 12/15/2010 12:00:00 AM Coffee NJ 12/15/2010 1:15:00 PM Beers NJ 12/15/2010 3:45:00 AM Cream Here is my desired output, which I guess a while/for loop or a pivot function could do the job but my experience is not there yet. Basically, I need to count the number of item sold from the Item_sold column incrementally (base line date starts from 12/8 to 12/9, 12/8 to 12/10, 12/8 to 12/11, 12/8 to 12/12...) I was wondering if anyone could edcuate and solve this problem. Many thanks in advance, Joe Location 12/8 |12/8-12/9 |12/8-12/10 |12/8 - 12/11 |12/8 - 12/12 |12/8 - 12/13 VA 0 0 2 0 0 3 DC 0 0 0 0 0 4

• Can a Domain Specific Language (DSL) be localized?

  - by michielvoo

  I have never written a DSL, but I am considering it as a feature for a new project (hypothetical). It would be for end users to be able to express in natural language concepts such as weekdays between 10 and 11 except on the first monday of the month. Dutch users might write weekdagen tussen 10 en 11 behalve op de eerste maandag van de maand. In this case the position of the words seems to match, but there may be expressions where the position of verbs/nouns etc. could be different between languages. I realise the obvious answer (it depends). I am a .NET developer and I consider using Boo but I'm open to suggestions. I need to understand wether each translation requires rewriting a part of the implementation (which part) or if there is a way to do actual translations, maybe in some sort of preprocessor. Thanks!

• CakePHP. How can i make a model test in a table with another primary key?

  - by Marcelo

  I have this table CREATE TABLE myexamples.problems ( id INT, name VARCHAR(45) NULL , pk_id INT AUTO_INCREMENT PRIMARY KEY ); But when I try test a model in cakephp, it fails because the table has two autoincrement attributes. The following query CREATE TABLE `test_suite_problems` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(45) DEFAULT NULL, `pk_id` int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (`pk_id`) ) DEFAULT CHARSET=latin1, COLLATE=latin1_swedish_ci, ENGINE=InnoDB; raise this error: "1075: Incorrect table definition; there can be only one auto column and it must be defined as a key" I have in the model class <?php class Problem extends AppModel { var $name = 'Problem'; var $displayField = 'name'; var $primaryKey='problems'; } ?> But I don't know how to make the field ID not having an autoincrement attribute, and I can't change the table structure.

• How to make awkward pivot of sql table in SQL Server 2005?

  I have to rotate a given table from an SQL Server but a normal pivot just doesn't work (as far as i tried). So has anybody an idea how to rotate the table into the desired format?

• Segmentation fault when accessing a PHP page

  - by Justin Ethier

  Sometimes when one of our Apache web servers is restarted, we experience segmentation faults when any PHP page is subsequently accessed. The following line is printed in the httpd error_log: [Wed Jun 16 10:59:33 2010] [notice] child pid 31513 exit signal Segmentation fault (11) There will be one of these lines for each PHP page that is accessed. This appears to happen randomly - the "workaround" to-date is to restart httpd, which eventually fixes the problem (almost always after a single restart). Although we only see this happen rarely, it still happens frequently enough to be of concern. So my question is, why is this happening in the first place? Is this a known bug with the version of Apache / PHP / Linux / etc that we are using? Any ideas? The environment is: Fedora 11 Apache 2.2.15 (Default settings) PHP 5.2.13 I can provide more information if that would help narrow things down, since this error message is rather generic... Any help is appreciated.

• Export products and variants from MSSQL

  - by mickyjtwin

  I have a SQL DB that has a table of products, and another table which contains a list of the sku variants of each product if it has one. I want to export all the products and their SKU's into excel. At the moment, I have a helper SQL function which performs the subquery against a product_id and concatenates all the SKU's into a comma-delimited string, e.g: Product Code, Name, SKUs 111 P1 77, 22, 11 Is there an easier way to do this, so that each SKU is a row which the associated product code as well, i.e: Product Code, Name, SKUs 111 P1 77 111 P1 22 111 P1 11

• MinGW and "delcaration does not declare anything"

  - by Bob Somers

  I'm working on converting a Linux project of mine to compile on Windows using MinGW. It compiles and runs just fine on Linux, but when I attempt to compile it with MinGW it bombs out with the following error message: camera.h:11: error: declaration does not declare anything camera.h:12: error: declaration does not declare anything I'm kind of baffled why this is happening, because I'm using the same version of g++ (4.4) on both Linux and Windows (via MinGW). The contents of camera.h is absurdly simple. Here's the code. It's choking on lines 11 and 12 where float near; and float far; are defined. #include "Vector.h" #ifndef _CAMERA_H_ #define _CAMERA_H_ class Camera{ public: Vector eye; Vector lookAt; float fov; float near; float far; }; #endif Thanks for your help.

• Dynamically removing records when certain columns = 0; data cleansing

  I have a simple card table: CREATE TABLE `users_individual_cards` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` char(36) NOT NULL, `individual_card_id` int(11) NOT NULL, `own` int(10) unsigned NOT NULL, `want` int(10) unsigned NOT NULL, `trade` int(10) unsigned NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `user_id` (`user_id`,`individual_card_id`), KEY `user_id_2` (`user_id`), KEY `individual_card_id` (`individual_card_id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1; I have ajax to add and remove the records based on OWN, WANT, and TRADE. However, if the user removes all of the OWN, WANT, and TRADE cards, they go to zero but it will leave the record in the database. I would prefer to have the record removed. Is checking after each "update" to see if all the columns = 0 the only way to do this? Or can I set a conditional trigger with something like: //psuedo sql AFTER update IF (OWN = 0, WANT = 0, TRADE = 0) DELETE What is the best way to do this? Can you help with the syntax?

• MySQL storing negative and positive decimals

  - by Shishant

  Hello, I want to be able to store -11.99 and +11.99 kind of values in mysql db I am thinking of decimals instead of varchar. But reading mysql site I found out that its incompatible with older versions of mysql As a result of the change from string to numeric format for DECIMAL storage, DECIMAL columns no longer store a leading + or - character or leading 0 digits. Before MySQL 5.0.3, if you inserted +0003.1 into a DECIMAL(5,1) column, it was stored as +0003.1. As of MySQL 5.0.3, it is stored as 3.1. For negative numbers, a literal - character is no longer stored. Applications that rely on the older behavior must be modified to account for this change. So what should be the data type, If I have to give up varchar and make it compatible with older versions too?

• Can't access annotation property of subclassed uibutton - editted

  - by Tzur Gazit

  Below is my original question. I kept investigating and found out that the type of the button I allocate is of type UIButton instead of the subclassed type CustomButton. the capture below is the allocation of the button and connection to target. I break immediately after the allocation and check the button type (po rightButton at the debugger console). It's turned out tht the type is UIButton instead of CustomButton. CustomButton* rightButton = [CustomButton buttonWithType:UIButtonTypeDetailDisclosure]; [rightButton addTarget:self action:@selector(showDetails:) forControlEvents:UIControlEventTouchUpInside]; I have a mapView to which I add annotations. The pin's callout have a button (rightCalloutAccessoryView). In order to be able to display various information when the button is pushed, i've subclassed uibutton and added a class called "Annotation". @interface CustomButton : UIButton { NSIndexPath *indexPath; Annotation *mAnnotation; } @property (nonatomic, retain) NSIndexPath *indexPath; @property (nonatomic, copy) Annotation *mAnnotation; - (id) setAnnotation2:(Annotation *)annotation; @end Here is "Annotation": @interface Annotation : NSObject <MKAnnotation> { CLLocationCoordinate2D coordinate; NSString *mPhotoID; NSString *mPhotoUrl; NSString *mPhotoName; NSString *mOwner; NSString *mAddress; } @property (nonatomic, assign) CLLocationCoordinate2D coordinate; @property (nonatomic, copy) NSString *mPhotoID; @property (nonatomic, copy) NSString *mPhotoUrl; @property (nonatomic, copy) NSString *mPhotoName; @property (nonatomic, copy) NSString *mOwner; @property (nonatomic, copy) NSString *mAddress; - (id) initWithCoordinates:(CLLocationCoordinate2D)coordinate; - (id) setPhotoId:(NSString *)id url:(NSString *)url owner:(NSString *)owner address:(NSString *)address andName:(NSString *)name; @end I want to set the annotation property of the uibutton at - (MKAnnotationView *)mapView:(MKMapView *)pMapView viewForAnnotation:(id )annotation, in order to refer to it at the button push handler (-(IBAction) showDetails:(id)sender). The problem is that I can't set the annotation property of the button.

  I am using a custum UITableViewCell , which has some labels , buttons imageviews to be displayed.There is one label in the cell whose text is a NSString object and the length of string could be variable , due to this i cannot set a constant height to the cell in UITableViews : heightForCellAtIndex method.The ceels height depends on the labels height , whcich can be determined using the NSStrings sizeWithFont method . i tried using it , but looks like i m going wrong somewhere . Can anyone help me out in this , adding the code used in iniatilizing the cell if (self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier]) { self.selectionStyle = UITableViewCellSelectionStyleNone; UIImage *image = [UIImage imageNamed:@"dot.png"]; imageView = [[UIImageView alloc] initWithImage:image]; imageView.frame = CGRectMake(45.0,10.0,10,10); headingTxt = [[UILabel alloc] initWithFrame: CGRectMake(60.0,0.0,150.0,post_hdg_ht)]; [headingTxt setContentMode: UIViewContentModeCenter]; headingTxt.text = postData.user_f_name; headingTxt.font = [UIFont boldSystemFontOfSize:13]; headingTxt.textAlignment = UITextAlignmentLeft; headingTxt.textColor = [UIColor blackColor]; dateTxt = [[UILabel alloc] initWithFrame:CGRectMake(55.0,23.0,150.0,post_date_ht)]; dateTxt.text = postData.created_dtm; dateTxt.font = [UIFont italicSystemFontOfSize:11]; dateTxt.textAlignment = UITextAlignmentLeft; dateTxt.textColor = [UIColor grayColor]; NSString * text1 = postData.post_body; NSLog(@"text length = %d",[text1 length]); CGRect bounds = [UIScreen mainScreen].bounds; CGFloat tableViewWidth; CGFloat width = 0; tableViewWidth = bounds.size.width/2; width = tableViewWidth - 40; //fudge factor //CGSize textSize = {width, 20000.0f}; //width and height of text area CGSize textSize = {245.0, 20000.0f}; //width and height of text area CGSize size1 = [text1 sizeWithFont:[UIFont systemFontOfSize:11.0f] constrainedToSize:textSize lineBreakMode:UILineBreakModeWordWrap]; CGFloat ht = MAX(size1.height, 28); textView = [[UILabel alloc] initWithFrame:CGRectMake(55.0,42.0,245.0,ht)]; textView.text = postData.post_body; textView.font = [UIFont systemFontOfSize:11]; textView.textAlignment = UITextAlignmentLeft; textView.textColor = [UIColor blackColor]; textView.lineBreakMode = UILineBreakModeWordWrap; textView.numberOfLines = 3; textView.autoresizesSubviews = YES; [self.contentView addSubview:imageView]; [self.contentView addSubview:textView]; [self.contentView addSubview:webView]; [self.contentView addSubview:dateTxt]; [self.contentView addSubview:headingTxt]; [self.contentView sizeToFit]; [imageView release]; [textView release]; [webView release]; [dateTxt release]; [headingTxt release]; } textView = [[UILabel alloc] initWithFrame:CGRectMake(55.0,42.0,245.0,ht)]; this is the label whose height and widh are going wrong

• Dynamically register constructor methods in an AbstractFactory at compile time using C++ templates

  - by Horacio

  When implementing a MessageFactory class to instatiate Message objects I used something like: class MessageFactory { public: static Message *create(int type) { switch(type) { case PING_MSG: return new PingMessage(); case PONG_MSG: return new PongMessage(); .... } } This works ok but every time I add a new message I have to add a new XXX_MSG and modify the switch statement. After some research I found a way to dynamically update the MessageFactory at compile time so I can add as many messages as I want without need to modify the MessageFactory itself. This allows for cleaner and easier to maintain code as I do not need to modify three different places to add/remove message classes: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <inttypes.h> class Message { protected: inline Message() {}; public: inline virtual ~Message() { } inline int getMessageType() const { return m_type; } virtual void say() = 0; protected: uint16_t m_type; }; template<int TYPE, typename IMPL> class MessageTmpl: public Message { enum { _MESSAGE_ID = TYPE }; public: static Message* Create() { return new IMPL(); } static const uint16_t MESSAGE_ID; // for registration protected: MessageTmpl() { m_type = MESSAGE_ID; } //use parameter to instanciate template }; typedef Message* (*t_pfFactory)(); class MessageFactory· { public: static uint16_t Register(uint16_t msgid, t_pfFactory factoryMethod) { printf("Registering constructor for msg id %d\n", msgid); m_List[msgid] = factoryMethod; return msgid; } static Message *Create(uint16_t msgid) { return m_List[msgid](); } static t_pfFactory m_List[65536]; }; template <int TYPE, typename IMPL> const uint16_t MessageTmpl<TYPE, IMPL >::MESSAGE_ID = MessageFactory::Register( MessageTmpl<TYPE, IMPL >::_MESSAGE_ID, &MessageTmpl<TYPE, IMPL >::Create); class PingMessage: public MessageTmpl < 10, PingMessage > {· public: PingMessage() {} virtual void say() { printf("Ping\n"); } }; class PongMessage: public MessageTmpl < 11, PongMessage > {· public: PongMessage() {} virtual void say() { printf("Pong\n"); } }; t_pfFactory MessageFactory::m_List[65536]; int main(int argc, char **argv) { Message *msg1; Message *msg2; msg1 = MessageFactory::Create(10); msg1->say(); msg2 = MessageFactory::Create(11); msg2->say(); delete msg1; delete msg2; return 0; } The template here does the magic by registering into the MessageFactory class, all new Message classes (e.g. PingMessage and PongMessage) that subclass from MessageTmpl. This works great and simplifies code maintenance but I still have some questions about this technique: Is this a known technique/pattern? what is the name? I want to search more info about it. I want to make the array for storing new constructors MessageFactory::m_List[65536] a std::map but doing so causes the program to segfault even before reaching main(). Creating an array of 65536 elements is overkill but I have not found a way to make this a dynamic container. For all message classes that are subclasses of MessageTmpl I have to implement the constructor. If not it won't register in the MessageFactory. For example commenting the constructor of the PongMessage: class PongMessage: public MessageTmpl < 11, PongMessage > { public: //PongMessage() {} /* HERE */ virtual void say() { printf("Pong\n"); } }; would result in the PongMessage class not being registered by the MessageFactory and the program would segfault in the MessageFactory::Create(11) line. The question is why the class won't register? Having to add the empty implementation of the 100+ messages I need feels inefficient and unnecessary.

• How to access a grid inside of a RichTextBox in Silverlight 4?

  - by benrick

  I am trying to allow a user to create a table inside of a RichTextBox. I can create a Grid inside of the RichTextBox, but I am having some issues with it. I start with this XAML in the Grid. <RichTextBox Name="TB1" AcceptsReturn="True"> <Paragraph TextAlignment="Center"> Hi everybody </Paragraph> <Paragraph> <InlineUIContainer> <Grid Background="Black"> <Grid.RowDefinitions> <RowDefinition Height="10" /> <RowDefinition Height="10" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="10" /> <ColumnDefinition Width="10" /> </Grid.ColumnDefinitions> </Grid> </InlineUIContainer> </Paragraph> <Paragraph> How are you today? </Paragraph> </RichTextBox> Then when I get the XAML out using the Xaml property of the RichTextBox I get this XAML. <Section xml:space="preserve" HasTrailingParagraphBreakOnPaste="False" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> <Paragraph FontSize="11" FontFamily="Portable User Interface" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Center"> <Run Text="Hi everybody" /> </Paragraph> <Paragraph FontSize="11" FontFamily="Portable User Interface" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left"> <Run /> </Paragraph> <Paragraph FontSize="11" FontFamily="Portable User Interface" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left"> <Run Text="How are you today?" /> </Paragraph> </Section> Notice here that the Grid has turned into an empty Run element. Anyone know why this happens?
