• Is it possible in Scala to force the caller to specify a type parameter for a polymorphic method ?

  - by Alex Kravets

  //API class Node class Person extends Node object Finder { def find[T <: Node](name: String): T = doFind(name).asInstanceOf[T] } //Call site (correct) val person = find[Person]("joe") //Call site (dies with a ClassCast inside b/c inferred type is Nothing) val person = find("joe") In the code above the client site "forgot" to specify the type parameter, as the API writer I want that to mean "just return Node". Is there any way to define a generic method (not a class) to achieve this (or equivalent). Note: using a manifest inside the implementation to do the cast if (manifest != scala.reflect.Manifest.Nothing) won't compile ... I have a nagging feeling that some Scala Wizard knows how to use Predef.<:< for this :-) Ideas ?

• Prevent web2py from caching ?

  - by Joe

  Hi ! I'm working with web2py and for some reason web2py seems to fail to notice when code has changed in certain cases. I can't really narrow it down, but from time to time changes in the code are not reflected, web2py obviously has the old version cached somewhere. The only thing that helps is quitting web2py and restarting it (i'm using the internal server). Any hints ? Thank you !

• Why is my SSH session timing out in less than a minute?

  - by John Smith

  Within a minute of connecting to my remote Linux server through SSH, my session times out and I cannot contact the server until a few seconds have passed. Meanwhile, I'm connected to other servers without interruption. This is only happening when I establish connection from an hotel wireless AP. When I connect from my phone's Internet, the problem does not occur. Does anyone know what might be causing these unusual timeouts?

• No class def find error

  - by John Smith

  I have the following piece of code which helps me to read the paths of all the files in a directory and its subdirectories : File dir = new File("directory path"); try { System.out.println("Getting all files in " + dir.getCanonicalPath() + " including those in subdirectories"); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } List<File> files = (List<File>) FileUtils.listFiles(dir, TrueFileFilter.INSTANCE, TrueFileFilter.INSTANCE); for (File file : files) { try { System.out.println("file: " + file.getCanonicalPath()); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } } The problem is that I get a java.lang.NoClassDefFoundError: org/apache/commons/io/filefilter/TrueFileFilter error. I've imported the necessary libraries. I mention that I work on a plugin project. This code runs in a class with main function. I don't understand why it gave me this error. Thank you !

• SharePoint Returning a 401.1 for a Specific User/Computer

  - by Joe Gennari

  We have a SharePoint Services 3.0 site set up supporting about 300 users right now. This report is isolated and has never been duplicated. We have one AD user who cannot log into the SharePoint site with his account from his machine and is subsequently returned a 401.1 error. If any other user tries to log on with their account from his machine, it works okay. If he moves to another machine and logs on, it works okay. The only solution to this point has been to install FireFox on the machine. When he authenticates with FF, everything is okay. Remedies tried so far: Cleared cookies/cache Turned off/on Integrated Windows Authentication in IE Downgraded IE 8 to IE 6 Removed site from Intranet Sites zone Renamed the machine Disjoined/Rejoined Domain

• Get the co-ordinates of a touch event on Android

  - by Joe

  Hi, I'm new to Android, I've followed the hello world tutorial through and have a basic idea of what's going on. I'm particularly interested in the touch screen of my T-Mobile Pulse so just to get me started I want to be able to write the co-ordinates of a tocuh event on the screen, so say the user touched the co-ordinate 5,2 - a textview on the screen would display that. At present I have a simple program that just loads an xml file which contains the textview I intend to write the co-ordinates in. Thank you in advance, I did Google for help and searched stackoverflow but everything I found either went way over my head or wasn't suitable for this. Cheers.

• Language restrictions on iPhone lifted?

  - by John Smith

  Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

• Multiple PictureBoxs' C#

  - by Austin Smith

  I'm having a hard time figuring this out. I know pictureBox only lets you display one image a time. I'm trying to create a pictureBox for each image in my collection. For instance if I have ten images in my List, then the method should create ten pictureBox for those respective images so each one is displayes in a pictureBox. I'm not sure which would be better a for loop or a foreach loop instead. every time the loop increments both the varaiables XCoordinate and YCoordinate which are the location of the PictireBox shoulld increase so that the PictureBox won't overlap one another in the Form. The reason for the method is that the number of images in the collection can change everytime the application will run. That's why I'm not creating them manually. So after its done all the pictures in the list should appear in a picture.Box. The box should be all the same size the only difference is the location on the form and the images inside them. Please any help and I will be grateful

• Spring security with database and multiple roles?

  - by Joe

  I'm trying to make an application using spring 3.0. Now I've decided to try my hand at spring-security and hibernate. I've already seen that it's possible to back it with a databasem and I've seen a reference to defining your own queries? Now the problem I have is that the tutorials I've been finding aren't too clear and that they assume that a user can only have one role. I want to give some users multiple roles. So I was thinking about a database scheme along the lines of: User: user_id username password registrationDate User_Role: user_id role_id Role: role_id rolename Now I was wondering if anyone had some pointers to some usefull tutorials/advice/comments.

• hibernate many to many only save the new object and between table

  - by Joe

  I have the following tables: Student Student_Course Course Now when I create a student I only want to create a user and add a row to student_course. The "problem" I have is that when I set the set of courses in Student to cascade="save-update" that an update is also invoked on course. I was wondering if there was a way to prevent this.

• Load php file wth xml header

  - by John Smith

  I have a php file with an xml header and xml code, named test.php. How do I load this file as an xml? The following doesn't work: $xml = simplexml_load_file('test.php'); echo $xml; I just get a white page. The test file is saved as php, as it's dynamic. It's loading data from the tradedoubler api. The xml looks something like this: <voucherList> <voucher> <id>115</id> <programId>111</programId> <programName>Program 111</programName> <code>AF30C5</code> <updateDate>1332422674941</updateDate> <startDate>1332370800000</startDate> <endDate>1363906800000</endDate> <title>Voucher number one</title> <shortDescription>Short description of the voucher.</shortDescription> <description>This is a long version of the voucher description.</description> <voucherTypeId>1</voucherTypeId> <defaultTrackUri>http://clk.tradedoubler.com/click?a(222)p(111)ttid(13)</defaultTrackUri> <siteSpecific>True</siteSpecific> </voucher> <voucher> <id>116</id> <programId>111</programId> <programName>Program 111</programName> <code>F90Z4F</code> <updateDate>1332423212631</updateDate> <startDate>1332370800000</startDate> <endDate>1363906800000</endDate> <title>The second voucher</title> <shortDescription>Short description of the voucher.</shortDescription> <description>This is a long version of the voucher description.</description> <voucherTypeId>1</voucherTypeId> <defaultTrackUri>http://clk.tradedoubler.com/click?a(222)p(111)ttid(13)url(http://www.example.com/product?id=123)</defaultTrackUri> <siteSpecific>False</siteSpecific> <landingUrl>http://www.example.com/product?id=123</landingUrl> </voucher> </voucherList>

• How do I display each view once as they are loaded, in Android?

  - by Joe Masilotti

  I have an Android application that works off of a smaller database, around 300 entries. To view the database, I have created a custom view that contains individual rows of data. Then I query the database, and add each line to a newly created custom view. The problem is that it takes a little white for all of this to be created/loaded, so when you open the application, it sits for a few seconds. How can I load one line of data, then display it, then the next, append it, etc.?

• Java - How to pass a Generic parameter as Class<T> to a constructor

  - by Joe Almore

  I have a problem here that still cannot solve, the thing is I have this abstract class: public abstract class AbstractBean<T> { private Class<T> entityClass; public AbstractBean(Class<T> entityClass) { this.entityClass = entityClass; }... Now I have another class that inherits this abstract: @Stateless @LocalBean public class BasicUserBean<T extends BasicUser> extends AbstractBean<T> { private Class<T> user; public BasicUserBean() { super(user); // Error: cannot reference user before supertype contructor has been called. } My question is how can I make this to work?, I am trying to make the class BasicUserBean inheritable, so if I have class PersonBean which inherits BasicUserBean then I could set in the Generic the entity Person which also inherits the entity BasicUser. And it will end up being: @Stateless @LocalBean public class PersonBean extends BasicUserBean<Person> { public PersonBean() { super(Person.class); } ... I just want to inherit the basic functionality from BasicUserBean to all descendants, so I do not have to repeat the same code among all descendants. Thanks!.

• Is there a way to force Report Builder to use "WITH (NOLOCK)" in the queries it generates?

  - by Joe Pineda

  Hi. At work, users are very happy to generate their own reports using Reporting Services' Report Builder. But, alas, the queries it generates are very inefficient, and they don't use "WITH (NOLOCK)" - slowing down things for everyone. These are reports that really do need to be run using latest data - can't be offloaded to the reporting server. And since they query very specific, detailed data, hypercubes are of no use here. So the question is: Is there a way to configure Report Builder's Data Models so the queries it generates always use "WITH (NOLOCK)" when querying a table?

• How can I run Gcov over an installed Cocoa application?

  - by Joe

  I have a Cocoa application which uses an installer. I want to be able to run code coverage over the code (after it has been installed). This is not the usual unit-test scenario where a single binary will run a suite of tests. Rather, the tests in question will interact with the UI and the app back-end whilst it is running, so I ideally want to be able to start the application knowing that Gcov is profiling it and then run tests against it. Any ideas?

• Can freetextbox display links that were not explicitly added?

  - by Joe

  I would like to display links that are pasted in as links rather than text but freetextbox does not seem to do this. For instance, if somebody pastes in http://www.stackoverflow.com it looks like a link but shows up only as text. Do I need to convert this myself or is there a setting in the editor to take care of this?

• Trying to understand crash log output

  I'm trying to understand debug output from a crash log. I have the following line from the crashlog: 22 FG 0x00022b94 0x1000 + 138132 I understand how to use atos on 0x00022b94 to get the source code location. What I would like to know is why the crash log helpfully splits that number into 0x1000 + 138132? I have googled and the googles failed me.
