  • Program crash for array copy with ifort

    - by Stefano Borini
    This program crashes with Illegal instruction: 4 on MacOSX Lion and ifort (IFORT) 12.1.0 20111011 program foo real, pointer :: a(:,:), b(:,:) allocate(a(5400, 5400)) allocate(b(5400, 3600)) a=1.0 b(:, 1:3600) = a(:, 1:3600) print *, a print *, b deallocate(a) deallocate(b) end program The same program works with gfortran. I don't see any problem. Any ideas ? Unrolling the copy and performing the explicit loop over the columns works in both compilers. Note that with allocatable instead of pointer I have no problems. The behavior is the same if the statement is either inside a module or not. I confirm the same behavior on Linux using ifort (IFORT) 12.1.3 20120130.

  • Are global comment systems a privacy concern?

    - by Stefano Borini
    I more and more see these global login-once comment-everywhere systems on every page. I didn't do my homework of tinkering debugging and search before asking, so my question is as follows: You login on site A and leave a comment. Now you go on site B, which uses the same global comment system. At the bottom of the page a request form with your name and data appears for you to add a comment on B page. You don't leave any comment and browse away. Does the global-comment provider get information about the fact that you visited page B, even if you don't leave any comment ? I will dig into the code as soon as I have time, but in the meanwhile I would like to ask your insights on this regard.

  • Start developing for macosx

    - by Stefano Borini
    hello, I would like to start developing for macosx. I need to create a small native application to help me do some stuff. I never developed in Objective-C, have no idea about cocoa, Xcode, NIB and similar stuff. I don't want to learn by slapping examples together though. This would probably make things done, but I would not learn anything. I'd prefer a guided tutorial (or book) to go from zero to release on the web of the application. Do you have anything to suggest ?

  • Python library to detect if a file has changed between different runs?

    - by Stefano Borini
    Suppose I have a program A. I run it, and performs some operation starting from a file foo.txt. Now A terminates. New run of A. It checks if the file foo.txt has changed. If the file has changed, A runs its operation again, otherwise, it quits. Does a library function/external library for this exists ? Of course it can be implemented with an md5 + a file/db containing the md5. I want to prevent reinventing the wheel.

  • axis2 web service behave differently when tested with web service client or with local test class

    - by Stefano
    Hello I need to update a facade to some web service proxy classes to a third party web service, and expose them as a service. This for two reason : to maintain the same interface for all application that need to use the system : actually its migrating and there are a few differences in the third party ws (method names); and to expose a simplified interface. The third party has provided me with a manual and some pregenerated proxy classes to their service (the java file says generated with axis2 1,4) . I've used netbeans 6.8 and the axis2 plugin to create an axis2 service . This service contains the proxy classes and the facade class which instantiate the web service proxy and calls its method; the facade class is exposed as service. I've used axis2 1.4 (at beginnig and later 1.5 ) and tomcat 6.0. The first test i did was to call the facede methods from inside the project itself and it worked. Then i've created a new project with a jax-ws web service client to call my class deployed on axis2. At this point has happened two strange thing : In the axis2 services page has appeared the third party proxy class as if it were a new service (if i try to get the wsdl axis raises an error ). eg. the proxy interface is named WebServiceAPI (_stub is the concrete class) and , after the first call to my service , i find a new "WebServicesAPI1272968932531_1" service inside axis . The call obvoiusly fail i've began to sniff soap messages with wireshark and i've found they differs when using proxy classes direclty from my facade test class by the messages created after being deployed on axis. i've noticed they differs for the presence of the soap header in the failing message. any help would be greatly appreciated : maybe i messed up something, there might be some incompatibilities or version mistakes? below i've added the signature of the third party proxy, its impementation and the different soap messages: /* * WebServicesAPI.java * This file was auto-generated from WSDL * by the Apache Axis2 version: 1.4 Built on : Apr 26, 2008 (06:24:30 EDT) */ package com.ibm.eci.wsapi;

    I'm looking for an algorithm that rotates an image by some degrees (input). public Image rotateImage(Image image, int degrees) (Image instances could be replaced with int[] containing each pixel RGB values, My problem is that i need to implement it for a JavaME MIDP 2.0 project so i must use code runnable on JVM prior to version 1.5 Can anyone help me out with this ? EDIT: I forgot to mention that i don't have SVG APIs available and that i need a method to rotate by arbitrary degree other than 90 - 180- 270 Also, no java.awt.* packages are available on MIDP 2.0

  • Updating DetailViewController from RootController

    - by Stefano Salmaso
    I'm trying to create an iPad application with a similar user interface to Apple's Mail application, i.e: RootView controller (table view) on the left hand side of the split view for navigation with a multiple view hierarchy. When a table cell is selected a new table view is pushed on the left hand side The new view on the left side can update the detail view. I can accomplish both tasks BUT NOT TOGETHER. I mean I can make a multi-level table view in the RootController.(HERE you can find the working source code). Or I can make a single-level table view in the RootController which can update the detailViewController (here there is the source code:http://www.megaupload.com/?d=D6L0463G). Can anyone tell me how to make a multi-level table in the RootController which can update a detailViewController? There is more source code at the link but below is the method in which I presume I have to declare a new detailViewController (which has to be put in the UISplitViewController): - (void)tableView:(UITableView *)TableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; // if([Children count] == 0) { /* Create and configure a new detail view controller appropriate for the selection. */ NSUInteger row = indexPath.row; UIViewController <SubstitutableDetailViewController> *detailViewController = nil; if (row == 0) { FirstDetailViewController *newDetailViewController = [[FirstDetailViewController alloc]initWithNibName:@"FirstDetailView" bundle:nil]; detailViewController = newDetailViewController; } if (row == 1) { SecondDetailViewController *newDetailViewController = [[SecondDetailViewController alloc]initWithNibName:@"SecondDetailView" bundle:nil]; detailViewController = newDetailViewController; } // Update the split view controller's view controllers array. NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil]; splitViewController.viewControllers = viewControllers//nothing happens..... [viewControllers release];// } else { //Prepare to tableview. RootViewController *rvController = [[RootViewController alloc]initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]]; //Increment the Current View rvController.current_level += 1; //Set the title; rvController.current_title = [dictionary objectForKey:@"Title"]; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController.tableView reloadData]; //without this instrucion,items won't be loaded inside the second level of the table [rvController release]; } }

  • Weird landscape UITabBarController Application startup

    - by Stefano Verna
    Hi there. My application is quite simple, but I have some problems when it starts. I setted in the Info.plist to be landscaped, but it seems to ignore the order. In fact, when the app is loading the Simulator is landscaped, but then it returns in portrait mode. This is the hierarchy of the views and controllers: MainViewController (extends UITabBarController just to override shouldAutorotateToInterfaceOrientation:) Three extended UITableViewControllers as tabs (also those have the shouldAutorotateToInterfaceOrientation correctly setted up). If I kinda force the orientation of the device to Landscape with: [[UIDevice currentDevice] setOrientation: UIInterfaceOrientationLandscapeRight]; Then for an instant the Simulator flashes in portrait mode, and then it goes landscaped. The problem is that in this way, the auto-rotation animations gets started, which is something I cannot tollerate. I just want a fixed, landscaped application. Any clues? Am I missing something?

    I'm using the code above to dynamically allocate an array, do some work inside the function, return an element of the array and free the memory outside of the function. But when I try to deallocate the array it doesn't free the memory and I have a memory leak. The debugger pointed to the myArray variable shows me the error CXX0030. Why? struct MYSTRUCT { char *myvariable1; int myvariable2; char *myvariable2; .... }; void MyClass::MyFunction1() { MYSTRUCT *myArray= NULL; MYSTRUCT *myElement = this->MyFunction2(myArray); ... delete [] myArray; } MYSTRUCT* MyClass::MyFunction2(MYSTRUCT *array) { array = (MYSTRUCT*)operator new(bytesLength); ... return array[X]; }

  • ERB doesnt get executed in javascript scripts

    - by Stefano
    Hi guys I have a select input on my page. this select input displays/hides fields in the form. This all works fine. But the problem is that if i submit the form and lack some necessary fields, it doesnt set the select to the right value afterwards. I just cant get the embedded ruby to work! it keeps escaping the whole thing... here my code: $(document).ready(function() { $("#profile_sex").val('<%= @profile.sex %>') $("#profile_sex").change(function(){ ($(this).val() == "Frau") ? $('#form-female').show() : $('#form-female').hide(); ($(this).val() == "Mann") ? $('#form-male').show() : $('#form-male').hide(); if ($(this).val() == "Paar") { $('#form-female').show(); $('#form-male').show(); } }); }); why doesnt this work??? I dont get any error or anything it just sets the value to "<%= @profile.sex =" I was googling and searching about on stack overflow and railscasts, the rails API, everything. Im seriously confused... thanks for your help.

  • How to expose a control collection to a property grid at design time

    - by Stefano Delendati
    I have a custom control that with a property that is a collection of custom object. This custom object hava a reference to some component/controls. When at design time I tray to add an item to the collection and select the object, VS tells me that the control is not serializable. This is the code (simplified version - but not to much): public class ViewRefObj { public control view { get; set; } public ViewRefObj() { } } private List<ViewRefObj> _controls=new List<ViewRefObj>(); public List<ViewRefObj> Views { get { return _controls; } }

  • SELECT product from subclass: How many queries do I need?

    - by Stefano
    I am building a database similar to the one described here where I have products of different type, each type with its own attributes. I report a short version for convenience product_type ============ product_type_id INT product_type_name VARCHAR product ======= product_id INT product_name VARCHAR product_type_id INT -> Foreign key to product_type.product_type_id ... (common attributes to all product) magazine ======== magazine_id INT title VARCHAR product_id INT -> Foreign key to product.product_id ... (magazine-specific attributes) web_site ======== web_site_id INT name VARCHAR product_id INT -> Foreign key to product.product_id ... (web-site specific attributes) This way I do not need to make a huge table with a column for each attribute of different product types (most of which will then be NULL) How do I SELECT a product by product.product_id and see all its attributes? Do I have to make a query first to know what type of product I am dealing with and then, through some logic, make another query to JOIN the right tables? Or is there a way to join everything together? (if, when I retrieve the information about a product_id there are a lot of NULL, it would be fine at this point). Thank you

    I have searched for PDF reader library that is licenced under LGPL or the like but could not find. I found only GPLs. Now I need a help to write my own library to read the PDF file and display it in my app. I have downloaded PDF Specs 1.7 from Adobe and I'm trying to search out a beginner tutorial but I'm yet to find one. Is there a beginner tutorial for writing my own reader library (only reader)? Thanks
