Hi,
I'm starting learning Ruby on Rails. So my application, like every Rails app, has three databases:
Development
Test
Production
And the question is: how do i switch from a db to another?
Thanks
I'm a Java developer looking to learn some C#/ASP.NET. One thing I've never liked about .NET from the get-go was that it didn't have support for MVC. But now it does! So I was wondering if anybody knew where to get started learning C# MVC.
Also, do you need the non-free version of developer-studio to do this?
I'm trying to use Eclipse + PyDev for studying OpenGL programming but when I type
from OpenGL.GL import *
from OpenGL.GLUT import *
IDE becomes extremely slow!
Ok. It isn't a smart idea import to much useless things but it's so useful for learning a new library!
Any help?
PS: I use Ubuntu with Eclipse Galileo.
I am learning objective c and am making some small programs. for my current project i am taking a NSBox and changing it's location based on a random number. How do I change the box's location? With C# it was a simple "box.location = anotherLocation" but I can't figure out how to do this in objective c. Any help would be greatly appreciated.
Thanks.
I'm learning Node.js and looking forward to create a simple web application which will be based on Express
and I was thinking of something like creating user groups and each group has its own users and each group has its own permissions
(Just like ACL in Cakephp)
So can anyone recommend a good module or whatever to do so ?
Also I'm a little curious about security and how these passwords are going to be saved and what type of encryption the passwords will be encrypted in.
Thanks :)

Are there any books on debugging techniques? A friend of mine is learning to code and he asked me this question. I told him I don't know of any. Is it that you just have to go through the School of Hard Knocks to learn?
What should I learn after learning C++?
I have read C++ from books like C++ Primer, Effective C++ etc but now I want to learn some advanced topics.
So what should I learn now,any suggestions?

I'm learning Ruby on Rails.
I'm using some associations (has_many :through, ...)
But i'm having some problems with it when i'm combining my views.
How exactly do i combine these nested forms? Can i do this with partial forms and where do i have to write extra code for this? I have seen examples only use the "view" and others also edit the controller....
An example would be very nice :-)
I understand that there are already alot of web server out there.
But i feel like creating one for learning purpose.
Is it something i should try to figure out and any guides or tutorials on this?
I'm interested in learning about algorithms, both conceptually and practically, as a beginner. I want to learn about binary search trees and similar.
What tutorials and example programs, preferably in Python or Java, will help me?
My friend has convinced me to start learning some C++, so my question is simple: where can I find some good tutorials for it?
But please don't link me to the usual dry boring tutorials that only tells you the function syntax, I need more thorough explanations. I get sidetracked very easily, and I need tutorials that are more on a human level, that I'll not only learn from, but enjoy reading as well.
So I'd appreciate any links that would help :)
As someone who is interested in learning more about the security side of technology, I ask you all the following questions:
How is it that crackers crack software? What techniques are used to do so? I would imagine that the cracking methods depend upon the language the software is written in, right? Aside from using something like cloud-based security for SaaS ((software as a service) which isn't always an option), what choices does one have to prevent their software from being compromised?
I'm learning to use the PHP interactive shell, but I'm having trouble with multi-line code.
Using backslashes like in the UNIX shells doesn't seem to work. What am I doing wrong ?
php > function test(){\
php { echo "test";\
php { }\
php > test();
PHP Parse error: syntax error, unexpected T_ECHO, expecting T_STRING in php shell code on line 2
I want to start learning C++, so I downloaded Microsoft Visual Studio 2010 Express, and the entire application freezes and crashes every time I try to compile (debug and release build) something (I have tried running it in Admin Mode). Is there a good alternative compiler that I could still use VS 2010 as the IDE?
I'm interested in writing a chess engine (mostly as a learning exercise) and would be interested in any resources that people know of that could be of interest or use, anything really: Papers, Books, Theory, Tutorials, anything that could be useful.
Learning the basics of XML for the first time from W3C tutorials. How are most XML files generated? Does the server side application usually print a complete XML file to be parsed each time there is new data?
I have a CGI application in C and it includes the SQLite API. Is the best way to do some sort of printf to a XML file (using my data from the database) so it can be parsed?
Thanks.
I am new to design and learning the design principles.
It says deriving square from rectangle is a classic example of violation of Liskov's Substitution Principle.
If that's the case, what should be the correct design?

I am from a Java background and is learning C++. I encountered the following C++ code:
String source = String::New("'Hello' + ', World'");
As what I understand so far, this should be a call to static member function 'New' of class 'String'. But, I've searched through the whole header file defining 'String', there is not any static member named 'New' in the String class or its super classes. Is there any special meaning attached to String class or the New member function in C++?
Please give me some suggestions regarding a project topic in the TLA+ language. I'm taking a course on the language, it's the first year I'm learning about specification and verification and I have no clue what to choose to implement in two weeks time. Any ideas?
