Hello Guys!
I've two MS SQL tables: Category, Question. Each Question is assigned to exactly one Category. One Category may have many subcategories.
Category
Id : bigint (PK)
Name : nvarchar(255)
AcceptQuestions : bit
IdParent : bigint (FK)
Question
Id : bigint (PK)
Title : nvarchar(255)
...
IdCategory : bigint (FK)
How do I recursively count all Questions for a given Category (including questions in subcategories). I've tried it already based on several tutorials but still can't figure it out :(

From what I gather, there are two major methods to perform alignment on point clouds, Iterative Closest Point (ICP) and Particle Filtering. What are the advantages of each method? And can someone point me some good tutorials.
For what I am currently doing, I think ICP would be easier, I can't seem to find any simple reference implementations online for 2d point sets. Has anyone seen (psuedo)code for ICP with details on the transformation step?
Thanks in advance.

The Boost.Test documentation and examples don't really seem to contain any non-trivial examples and so far the two tutorials I've found here and here while helpful are both fairly basic.
I would like to have a master test suite for the entire project, while maintaining per module suites of unit tests and fixtures that can be run independently. I'll also be using a mock server to test various networking edge cases.
I'm on Ubuntu 8.04, but I'll take any example Linux or Windows since I'm writing my own makefiles anyways.
Right now, I'm more into design & maintenance of MFC based application. I'm seeing good progress and requirement for C#.Net application.

I'm trying to get jQuery to play a sound on element hover/click. (It's like a flash website without flash)
I've tried the methods recommended in Cross-platform, cross-browser way to play sound from Javascript?, the jQuery Sound plugin and a couple of other tutorials without any success. I'm assuming this is because they haven't been updated since 2008.
Does anyone have any recommendations?
I've been reading all kinds of tutorials on how to deploy rails apps on heroku from windows.
I've tried installing git, heroku gem, generating ssh keys and setting paths and everything...
I get either public key error (without putty) or fatal no auth found (with putty)...
I googled for some books on jquery and i got these
Jquery Books from learningjquery.com
and some video series from net.tutsplus.com and certainly some tutorials from Learningjquery.com for beginner...
But still a good book would do a lot in my learing... Any books that you would recommend for beginner in jquery to have a crack at it?
Anybody got any good reading articles and tutorials on custom installers
as most on the web seem to be outdated?
The MS e-book for the 70-536 exam covers this but very lightly, as it does not cover the use of the ServiceProcessInstaller class or something like that??? I'm mentioning this here because I have seen this on quite a few exams.
Possible Duplicates:
What is the easiest language to start with?
What programming language should I choose for an independent study language?
Well as the title says what language is good for a beginner and for a hobby? I'll probably be making some games or desktop apps with a gui most likely. I'll be working in Windows and Linux. Oh and could you also give some links to tutorials for the language?
