I am going to design a DW and I heard about materialized views. Actually I want to create a view and it should update automatically when base tables are changed. Can anyone explain with an query example..
I've written this really simple console based UI for a project. It seems to work fine but for some reason, it gets caught in an infinite loop somehow once the user inputs a non-String response to the menu selection.
void selection() {
System.out.println("\nSelection[1,2,3,4,5,0]: ");

So I've completely changed how BrainfuckSharp does things, and added some features. This is obviously a follow up to: Interpreting Brainfuck code to C#, then compiling to a .exe
It now features an OptimizationLevel (currently hardcoded, will fix for the future) that allows you to indicate how fa...
In this question I explain an issue I'm seeing with Powershell version 3 (which looks like a bug but I'm not sure what's going on yet) when I try to enable debug tracing (with Set-PSDebug -Trace 2).
Is there a better (perhaps more idiomatic) way to write this sort of filtering pipeline.
I have ...

I am creating a GUI application to run a calculator using Python. I've followed the majority of programming from the book. When I execute this code, it gives me the name error that self is not defined. This is confusing this it was introduced in the functions. Below is my code. This has been puzz...
I took a code from this website and I wanted to understand it and go throught it my question :
what does it mean to have this lines in the code
len_old = len(A)
(A, activated_nodes_of_this_round, cur_tried_edges) = \
_diffuse_one_round(G, A, tried_edges)
Well, there is a lot to talk about here...
I can't speak specifically about memory leaks here. I'm not sure how you're writing or compiling this code. But it's important to note that the iOS SDK absolutely does not automatically deallocate objects for you. Objective-C (in contrast to C#) is d...
I think the below code is difficult to understand. I also feel it abuses Java's ternary operator.

I developed a javascript component to display a tree, based on D3.js
I'm not sure how clean my code is, I'm not used to code a lot of javascript and I'm constrained to write everything in 1 file.
So I'd take every advice on how to make this code better.
And in particular, there's a behaviour I ...
The game itself works but i'm looking how to improve to computer generated choices. Random int gives the same choices a lot.

p_choice = raw_input('Choose rock, paper or scissors: ')
if p_choice.lower() in {'rock', 'paper', 'scissors'}:
