How to create a UserProfile form in Django with first_name, last_name modifications ?

- by Natim

If think my question is pretty obvious and almost every developer working with UserProfile should be able to answer it. However, I could not find any help on the django documentation or in the Django Book. When you want to do a UserProfile form in with Django Forms, you'd like to modify the profile fields as well as some User field. But there is no forms.UserProfileForm (yet?) ! How do you do that ?

ASP.NET MVC hosting problem, routing, handlers and modules

- by johnabs

Hi, This is one of them again, hosting with fasthosts. I recently purchased a windows developer package from them. When I tried to deploy my ASP.NET 3.5 MVC project, which was working fine with the same host on a reseller account, it is not working. The reason to move from reseller to a normal Windows Developer package is, the MS-SQL server database is too expensive in a reseller account, strange! I contact them, and they are saying they upgraded the control panel. The technical support said, I need to disable the Modules and Handlers from the web.config file. Also I need to deploy them as .dll files. I am not sure how to do that. The website is partially working now. I think the problem is now with the routing. I have not deployed any .dlls apart from the System.Web.Mvc.dll, System.Web.Routing.dll and System.Web.Abstractions.dll. I have not got a clue on how to deploy the Modules and Handlers. The code that I commented on the web.config file is as follows.  Anybody got any ideas please. Thank you for your time.

API to determine cell carrier?

- by Chris Lively

Is there a free API or some other way to determine what carrier a cell phone number is registered with? I'd like my application to broadcast text messages without them picking their carrier from a list. UPDATE: Interestingly, a coworker found the answer: http://developer.whitepages.com/ UPDATE2: Well the whitepages license agreement is so restrictive that you can't build an app for it. Any other ideas?

What are some viable alternatives to BizTalk Server?

- by Kilhoffer

In evaluating different systems integration strategies, I've come across some words of encouragement, but also some words of frustration over BizTalk Server. What are some pros and cons to using BizTalk Server (both from a developer standpoint and a business user), and should companies also consider open source alternatives? What viable alternatives are out there? EDIT: Jitterbit seems like an interesting choice. Open Source and seems to be nicely engineered. Anyone on here have any experience working with it?

Abstraction is for lame programmers ? [closed]

- by Zaban Khuli

Hi, there's this senior developer in my company who's (in his own opinion) a pretty good C programmer. I happen to be from functional background (ML, to be specific) and so for me composition and abstraction are the two basic elements of programming. But this MrSmartyPants has got some kind of superiority complex and he'd always argue with me that abstraction is for lame programmers and _real_ programmers do not need it. Is it a problem with this guy or all C programmers have this opinion that abstraction is for lame programmers?

How to make an eclipse plugin for text comparison of two files

- by Snehal

I plan to make a text comparison plugin for eclipse which basically provides a visual aid for changes that are required in the file and allows the user to accept or reject them. It is very much in lines of subclipse for svn or any other code comparison tools. I already found a good source to perform the text comparison but I'm looking for some pointers regarding the implementation of the UI in eclipse.

How to generate function call graphs for JavaScript?

- by Jeremy Rudd

Are there softwares that can generate graphs that show which functions call which functions? I need to analyze JavaScript source code, a language which Doxygen/Graphviz does not support, though it does support C++ and others. If there are no tools that support JavaScript out-of-the-box, is there a way to convert JS to C++ so I can use Doxygen itself?

How is parsing phase in a compiler different from a rule engine ?

- by abhinav

Hi, I have a rough understanding of how the compilers work (I mean languages, grammars, lexical analysis, parsing etc). The rule engines have various rules and associated action, just like you have rules in the grammars and you can associate actions with them in parser-generator tools like ANTLR. So I am a bit confused on how to differentiate between these two. Could anyone give a clearer, more formal explanation for the differences ? Thanks, Abhinav.

ORM market analysis

- by bonefisher

I would like to see your experience with popular ORM tools outhere, like NHibernate, LLBLGen, EF, S2Q, Genom-e, LightSpeed, DataObjects.NET, OpenAccess, ... From my exp: - Genom-e is quiet capable of Linq & performance, dev support - EF lacks on some key features like lazy loading, Poco support, pers.ignorance... but in 4.o it may have overcome .. - DataObjects.Net so far good, althrough I found some bugs - NHibernate steep learning curve, no 100% Linq support (like in Genom-e and DataObjects.Net), but very supportive, extensible and mature

What does it mean to "preconcat" a matrix?

- by Brad Hein

In reviewing: http://developer.android.com/reference/android/graphics/Canvas.html I'm wondering translate(): "preconcat the current matrix with the specified translation" -- what does this mean? I can't find a good definition of "preconcat" anywhere on the internet! The only place I can find it is in the Android Source - I'm starting to wonder if they made it up? :) I'm familiar with "concat" or concatenate, which is to append to, so what is a pre-concat?

java.sql.SQLException: Parameter number X is not an OUT parameter

- by Frederik

Hi guys, I'm struggling with getting the result OUT variable from a MySQL stored procedure. I get the following error: java.sql.SQLException: Parameter number 3 is not an OUT parameter The stored procedure looks like this: CREATE DEFINER=`cv_admin`@`localhost` PROCEDURE `CheckGameEligibility`( IN gID INT(10), IN uID INT(10), OUT result TINYINT(1) ) BEGIN # Do lots of stuff, then eventually: SET result = 1; END My java function takes an array of strings* and creates the CallableStatement object dynamically: public static int callAndReturnResult( String sql , String[] values ) { int out = 0 ; try { // construct the SQL. Creates: CheckGameEligibility(?, ?, ?) sql += "(" ; for( int i = 0 ; i < values.length ; i++ ) { sql += "?, " ; } sql += "?)" ; System.out.println( "callAndReturnResult("+sql+"): constructed SQL: " + sql ); // Then the statement CallableStatement cstmt = DB.prepareCall( sql ); for( int i = 0 ; i < values.length ; i++ ) { System.out.println( " " + (i+1) + ": " + values[ i ] ) ; cstmt.setString(i+1, values[ i ] ); } System.out.println( " " + (values.length+1) + ": ? (OUT)" ) ; cstmt.registerOutParameter( values.length + 1 , Types.TINYINT ); cstmt.execute(); out = cstmt.getInt( values.length ); cstmt.close(); } catch( Exception e ) { System.out.println( "*** db trouble: callAndReturnResult(" + sql + " failed: " + e ); e.printStackTrace() ; } return out ; } *) I suppose I should be using an int array instead of a string array, but it doesn't seem to be what the error message was about. Anyway, here's the output it generates: callAndReturnResult(CheckGameEligibility(?, ?, ?)): constructed SQL: CheckGameEligibility(?, ?, ?) 1: 57 2: 29 3: ? (OUT) *** db trouble: callAndReturnResult(CheckGameEligibility(?, ?, ?) failed: java.sql.SQLException: Parameter number 3 is not an OUT parameter at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1075) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:989) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:984) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:929) at com.mysql.jdbc.CallableStatement.checkIsOutputParam(CallableStatement.java:692) at com.mysql.jdbc.CallableStatement.registerOutParameter(CallableStatement.java:1847) at org.apache.commons.dbcp.DelegatingCallableStatement.registerOutParameter(DelegatingCallabl>eStatement.java:92) at Tools.callAndReturnResult(Tools.java:156) Any ideas what might be the problem? :) Thanks in advance!

Create an Xml file from an object

- by remi bourgarel

I work as a web developer with a web designer and we usually do like this : - I create the system , I generate some Xml files - the designer display the xml files with xslt Nothing new. My problem is that I use Xml Serialization to create my xml files, but I never use Deserialization. So I'd like to know if there is a way to avoid fix like these : empty setter for my property empty parameter-less constructor implement IXmlSerializable and throw "notimplementedexception" on deserialization do a copy of the class with public fields
